The elastic connector and the endoscope provided by the embodiment of the application are described in detail below by referring to fig. 1 to 8, and specific embodiments and application scenes thereof.
The present embodiment provides an elastic connection.
The elastic connector of the present embodiment is used for an endoscope, and can be used as a connector between the insertion portion 20 and the cable 30 and the handle 10, as shown in fig. 1 and 2. The endoscope of the present embodiment may be a disposable endoscope, a limited-time multiplexing endoscope, or an infinite-time multiplexing endoscope. The endoscope of the present embodiment may be a bronchoscope, a nephroscope, a esophagoscope, a gastroscope, a enteroscope, an otoscope, a rhinoscope, a stomatoscope, a laryngoscope, a colposcope, a laparoscope, an arthroscope, or the like. The present embodiment does not particularly limit the kind of endoscope.
The elastic connector of the present embodiment includes an elastic body 110, as shown in fig. 3 to 5. The elastic body 110 is made of a material having elasticity, such as silica gel, rubber, etc. The elastic body 110 may serve as a mounting base for the insertion portion 20 and the cable 30.
In some embodiments, the resilient body 110 is in sealing engagement with the housing 11 of the handle 10 of the endoscope. Illustratively, the elastic body 110 may be disposed at the distal end of the handle 10, and the elastic body 110 may not only serve as a mounting base for the insertion portion 20 and the cable 30, but also may serve as a sealing function for the distal end of the handle 10, as shown in fig. 1 and 2. Illustratively, the elastomeric body 110 is formed of a resilient material such that a sealed connection is achieved by an interference fit between the elastomeric body 110 and the end of the housing 11
In some embodiments, the elastic body 110 is provided with a first channel 111, as shown in fig. 3 and 5. The first channel 111 penetrates the elastic body 110, and the first channel 111 is used for mounting the insertion portion 20 of the endoscope, as shown in fig. 1 to 3 and 5. After the insertion portion 20 is mounted in the first channel 111, the proximal end of the insertion portion 20 may be placed in communication with the lumen of the handle 10 so that the instrument operation, negative pressure suction, etc. may be performed.
In some embodiments, the first channel 111 is in sealing connection with the insert 20. Illustratively, the sealed connection of the first channel 111 and the insert 20 may be achieved by an interference fit therebetween. Alternatively, a sealing ring may be provided between the first passage 111 and the insertion portion 20, by which sealing ring a sealing connection of the two is achieved.
In some embodiments, the elastic body 110 is provided with a second channel 112, as shown in fig. 3 and 5. The second channel 112 penetrates the elastic body 110, and the second channel 112 is used for installing the cable 30 of the endoscope, as shown in fig. 1-3 and 5. After the cable 30 is installed in the second channel 112, the proximal end of the cable 30 can be communicated with the inner cavity of the handle 10, so that the cable 30 can be connected with the chip in the inner cavity, and the image collected by the insertion portion 20 can be displayed on the display device.
In some embodiments, the second channel 112 is sealingly connected to the cable 30. By way of example, a sealed connection of the second channel 112 and the cable 30 may be achieved by an interference fit of the two. Alternatively, a sealing ring may be provided between the second channel 112 and the cable 30, by means of which sealing ring a sealing connection of the two is achieved.
Compared with the prior art in which the insertion portion 20 and the cable 30 are directly matched with the harder housing 11, the insertion portion 20 and the cable 30 of the embodiment are mounted on the elastic body 110 with elasticity, when the insertion portion 20 is bent, part of energy can be absorbed through deformation of the elastic body 110, so that the influence of bending of the insertion portion 20 on the sealing performance of the joint between the elastic body 110 and the insertion portion 20 can be reduced, and similarly, the influence of pulling action of the cable 30 on the sealing performance of the joint between the elastic body 110 and the cable 30 can be reduced through the elastic body 110. The elastic connector of the embodiment is used in an endoscope, so that the sealing performance of the endoscope can be improved.
That is, the elastic connector of the present embodiment solves the technical problem that the tightness of the housing 11 of the handle 10 in the related art is easily affected by the pulling action of the insertion portion 20 and the cable 30 by the elastic body 110.
In some embodiments, a first socket 1111 is disposed at a distal end of the first channel 111, and the first socket 1111 communicates with the first channel 111, as shown in fig. 3-5. Illustratively, the first socket 1111 may be formed with the first channel 111 extending distally. The first socket 1111 may be, for example, a structure integrally provided on the elastic body 110. The first socket 1111 and the first channel 111 are integrally formed.
In this embodiment, the first socket 1111 is disposed at the distal end of the first channel 111, and when the insertion portion 20 is bent, the first socket 1111 may bend along with the bending of the insertion portion 20, and the energy transferred from the distal end to the proximal end of the insertion portion 20 may be absorbed by the first socket 1111, so that the influence of the bending of the insertion portion 20 on the sealing property of the connection between the elastic body 110 and the housing 11 may be reduced.
In some embodiments, a second socket 1121 is further disposed at the distal end of the second channel 112, and the second socket 1121 communicates with the second channel 112, as shown in fig. 3-5. Illustratively, the second socket 1121 may be distally extending from the second channel 112. The second socket 1121 may be a structure integrally provided on the elastic body 110, for example. The second socket 1121 and the second channel 112 are integrally formed.
In this embodiment, the second sleeve joint portion 1121 is disposed at the distal end of the second channel 112, and when the cable 30 is pulled, the second sleeve joint portion 1121 can bend along with the pulling of the cable 30, and the second sleeve joint portion 1121 can absorb part of the energy transferred from the distal end to the proximal end of the cable 30, so as to reduce the influence of the pulling of the cable 30 on the tightness of the connection between the elastic body 110 and the housing 11.
In some embodiments, the first socket 1111 is further provided with a first slot 1111a, and/or the second socket 1121 is further provided with a second slot 1121a, as shown in fig. 4. Fig. 4 shows a schematic view of the first socket 1111 further provided with a first slot 1111a, and the second socket 1121 provided with a second slot 1121a. Without being limited thereto, the first slot 1111a may be provided only on the first socket 1111, or the second slot 1121a may be provided only on the second socket 1121.
In some embodiments, the first slot 1111a may be disposed along an axial direction of the first socket 1111, or may be disposed along a radial direction of the first socket 1111. The first slot 1111a may be one or more.
In some embodiments, the second slot 1121a may be disposed along an axial direction of the second socket 1121, or may be disposed along a radial direction of the second socket 1121. The second slot 1121a may be one or more.
The first slot 1111a is provided on the first socket portion 1111 in this embodiment, so that the problem that the first socket portion 1111 restricts the proximal end of the insertion portion 20 from bending due to the excessive hardness of the first socket portion 1111 can be avoided. In this embodiment, the second slot 1121a is provided on the second sleeve portion 1121, so that the problem that the proximal end of the cable 30 is easily broken due to limited bending of the proximal end of the cable 30 caused by excessive hardness of the second sleeve portion 1121 can be avoided.
In some embodiments, the elastic body 110 is further provided with a clamping portion 113, as shown in fig. 3 and 4. The locking portion 113 is disposed along an axial direction of the elastic body 110, and locks the locking portion 113 with the housing 11, as shown in fig. 1 and 2. Correspondingly, the shell 11 is provided with a notch 11-5, as shown in fig. 8. The notch 11-5 is configured to receive the clamping portion 113, as shown in fig. 2. By the arrangement of the clamping portion 113, the elastic body 110 and the housing 11 not only have connection in the circumferential direction but also have connection in the axial direction, and the clamping portion 113 can also play a guiding role when the elastic body 110 is mounted.
In some embodiments, the clamping portion 113 is further provided with a protruding portion 1131, as shown in fig. 3 and 4. The protruding portion 1131 protrudes from the surface of the elastic body 110, and the first channel 111 and/or the second channel 112 are at least partially located at the protruding portion 1131. Illustratively, the height of the protrusion 1131 protruding from the surface of the elastic body 110 gradually increases from the proximal end to the distal end, as shown in fig. 3 and 4. Illustratively, the clamping portion 113 is disposed on a side of the elastic body 110 having the first channel 111, where the first channel 111 is at least partially located at the protrusion 1131, and/or the clamping portion 113 is disposed on a side of the elastic body 110 having the second channel 112, where the second channel 112 is at least partially located at the protrusion 1131.
The first channel 111 and/or the second channel 112 of the present embodiment are at least partially located at the protruding portion 1131, so as to further reduce the influence of bending of the insertion portion 20 and/or pulling action of the cable 30 on the sealing performance at the connection between the elastic body 110 and the housing 11.
In some embodiments, the elastic body 110 is further provided with a first clamping groove 114 and a second clamping groove 115, as shown in fig. 4. The housing 11 includes a first housing 11-1 and a second housing 11-2 as shown in fig. 2. The first housing 11-1 is provided with a first clamping block 11-3, and the second housing 11-2 is provided with a second clamping block 11-4, as shown in fig. 6-8. The first clamping groove 114 is clamped with the first clamping block 11-3, and the second clamping groove 115 is clamped with the second clamping block 11-4. Through the first clamping groove 114 and the first clamping block 11-3 in clamping connection, the second clamping groove 115 and the second clamping block 11-4 in clamping connection can be connected through the elastic body 110 and the structure of the shell 11, and the connection stability between the elastic body 110 and the shell 11 can be enhanced.
In some embodiments, the first clamping groove 114 and/or the second clamping groove 115 are disposed obliquely in the radial direction of the housing 11. As shown in fig. 4, in the radial direction of the housing 11, the first clamping groove 114 and the second clamping groove 115 are both provided obliquely. Referring again to fig. 4, the first and second catching grooves 114 and 115 are inclined downward in the direction from the proximal end face to the distal end face of the elastic body 110, and in the mounting direction of the second housing 11-2 (also referred to as the upper side to the lower side direction of the elastic body 110).
The first clamping groove 114 and the second clamping groove 115 of the embodiment are obliquely arranged, which is favorable for the clamping connection between the first clamping groove 114 and the first clamping block 11-3 when the elastic body 110 is assembled on the first shell 11-1, and is favorable for the clamping connection between the second clamping groove 115 and the second clamping block 11-4 when the second shell 11-2 is assembled on the elastic body 110. On the other hand, the first clamping groove 114 and the second clamping groove 115 of the present embodiment are disposed obliquely, so as to further enhance the connection stability between the elastic body 110 and the housing 11.
In some embodiments, a first sealant layer is further disposed in the first clamping groove 114, and the first clamping groove 114 is fixedly connected with the first clamping block 11-3 through the first sealant layer, so that the connection stability of the elastic body 110 and the first housing 11-1 can be further enhanced.
In some embodiments, a second sealant layer is disposed in the second clamping groove 115, and the second clamping groove 115 is fixedly connected with the second clamping block 11-4 through the second sealant layer, so as to further enhance the connection stability of the elastic body 110 and the second housing 11-2.
In some embodiments, the elastic body 110 is further provided with an abutment surface 116, as shown in fig. 3. When the elastic body 110 is engaged with the housing 11, the distal end surface of the housing 11 abuts against the abutment surface 116, as shown in fig. 2. By providing the contact surface 116, the positioning function can be performed when the elastic body 110 is assembled, and the sealing property between the housing 11 and the elastic body 110 can be enhanced by the contact of the housing 11 and the contact surface 116.
In some embodiments, the elastic body 110 is further provided with a notch 117, as shown in fig. 3. The number of notches 117 is one or more. In this embodiment, the arrangement of the notch 117 can reduce the material consumption and reduce the production cost when the elastic body 110 is manufactured, and on the other hand, the arrangement of the notch 117 can increase the elasticity of the elastic body 110, so that the elastic body 110 has a larger deformation capability, the influence of the bending of the insertion portion 20 on the tightness of the connection between the elastic body 110 and the insertion portion 20 can be further reduced, and the influence of the pulling action of the cable 30 on the tightness of the connection between the elastic body 110 and the cable 30 can be further reduced.
The embodiment also provides an endoscope.
The endoscope of the present embodiment includes a handle 10, an insertion portion 20, and a cable 30, and both the insertion portion 20 and the cable 30 are connected to the handle 10 as shown in fig. 1. The endoscope further comprises an elastic connection according to any of the aspects of the present embodiments, which is provided at the distal end of the handle 10, as shown in fig. 1.
The endoscope of the present embodiment can reduce the influence of bending of the insertion portion 20 on the sealing property of the connection between the elastic body 110 and the insertion portion 20 and also reduce the influence of the pulling action of the cable 30 on the sealing property of the connection between the elastic body 110 and the cable 30.
