In the actual operation process, the operation table surface is often disordered due to a plurality of pipelines, and the cleanliness of the operation table surface is affected. At ordinary times, surgeons often hold a plurality of pipelines into bundles, wrap the bundles with outer layers of towel, and finally clamp the bundles with pliers to ensure the tidy operation table surface. Vascular clamps, towel clamps and the like are most commonly used as pliers at present to fix the pipeline, but the fixing manner cannot provide enough clamping force, so that the pipeline is not firmly fixed, and can easily slide in the use process, even slide from a sterile area to a contaminated area, or conversely, the pipeline in the contaminated area is pulled back to the sterile area, so that the risk of cross infection is increased.

In order to solve the above-mentioned problems, referring to fig. 1 to 7, the present embodiment provides a pipeline fixing clamp for an operating table, which includes a clamp body 1, two outer sheaths 2 and two adjusting assemblies 3;

one end of the pliers body 1 is provided with two first clamping parts 11 which can be relatively close to or far away from each other;

the two outer sheaths 2 are respectively provided with a second clamping part 21 on one side close to each other, each first clamping part 11 is sleeved with one outer sheath 2, and the two second clamping parts 21 are close to each other along with the two first clamping parts 11 so as to clamp the cloth wrapping the pipeline;

the adjusting component 3 is disposed between the outer sheath 2 and the first clamping portion 11, and is used for adjusting the position of the outer sheath 2 along the length direction of the first clamping portion 11, and one adjusting component 3 corresponds to one outer sheath 2.

When it is desired to secure the line, the surgeon first wraps the line in a clean cloth and places it between the first gripping portions 11 of the clamp body 1. By operating the handle portions of the clamp body 1, the first clamping portions 11 are brought close to each other, and the cloth surrounding the pipeline is preliminarily clamped. Next, the position of the outer sheath 2 is adjusted by the adjustment assembly 3. The adjustment assembly 3 allows the outer sheath 2 to be moved outwardly along the length of the primary clamping portion 11. The second clamping portion 21 will further tighten the tubing as the sheath 2 moves, providing a stronger clamping force, as shown in fig. 7. The design not only improves the reliability of fixation, but also reduces the risk of infection caused by the sliding of the pipeline, and is convenient for a surgeon to fix the pipeline firmly more conveniently.

Referring to fig. 3 and 4, in the present embodiment, the first clamping portion 11 has a toothed structure 111 along a length direction, the adjusting assembly 3 includes a first connecting member 31, a second connecting member 32 and an elastic member 33, the first connecting member 31 is located in the outer sheath 2 and hinged to the outer sheath 2, one end of the first connecting member 31 has a pawl 311 for adapting to the toothed structure 111, one end of the second connecting member 32 is hinged to the other end of the first connecting member 31, the second connecting member 32 is hinged to the outer sheath 2, the other end of the second connecting member 32 extends out of the outer sheath 2, and the elastic member 33 is disposed between the first connecting member 31 and the second connecting member 32 for making the pawl 311 close to the toothed structure 111.

The end of the second connecting piece 32 extending out of the outer sheath 2 is pressed by external force, the pawl 311 is driven to tilt up to avoid the toothed structure 111, the outer sheath 2 moves inwards on the first clamping part 11, the elastic piece 33 compresses and stores elastic potential energy, and after the second connecting piece 32 is not stressed, the elastic piece 33 releases the elastic potential energy, so that the pawl 311 is close to the teeth of the toothed structure 111.

The outer sheath 2 is pulled outwards, the pawl 311 moves along with the movement of the outer sheath 2, and the pawl 311 moves to the next stage tooth of the tooth-shaped structure 111 together with the elastic piece 33 to limit the inner movement of the outer sheath 2 on the first clamping part 11.

The surgeon presses the portion of the second coupling member 32 protruding from the outer sheath 2 to tilt the pawl 311 and avoid the toothed structure 111, so that the outer sheath 2 can be easily moved to adjust the position, which allows the outer sheath 2 to be moved inward. Once the second connector 32 is released, the resilient member 33 urges the pawl 311 back into engagement with the toothed structure 111, ensuring that the sheath 2 is secured in the desired position and that the sheath 2 cannot move inwardly.

The pawl 311 and the toothed structure 111 cooperate to effectively prevent the sheath 2 from sliding reversely under the action of external force, enhance the stability of fixation and reduce the risk caused by the sliding of the pipeline. The pawl 311 is a bent pawl and is integrally formed with the first connecting member 31. The first and second connection members 31 and 32 may be plastic members.

Referring to fig. 4, in the present embodiment, the second clamping portion 21 includes a protrusion 211 integrally formed with the outer sheath 2. The integrally formed arrangement avoids additional connection points or seams and enhances the strength and durability of the overall structure. The design of the protrusions 211 may be of various shapes (e.g. arc, trapezoid, etc.) to ensure an optimal clamping effect. The protrusions 211 are located on the opposite sides of the two second clamping portions 21. The provision of the protrusions 211 enables a better alignment and clamping of the pipeline, preventing the pipeline and cloth from falling out.

Referring to fig. 5, in the present embodiment, the second clamping portion 21 further includes a non-slip pad 212 located on the protrusion 211. The anti-slip pad 212 may be made of rubber, silicone or other materials having a high coefficient of friction, and the surface may have a concave-convex structure to enhance friction during clamping. Ensure that the cloth wrapping the pipeline is firmly fixed and prevented from sliding.

Referring to fig. 4, in the present embodiment, an end of the second connecting member 32 extending out of the outer sheath 2 is tilted upward to form a pressing portion 321. The pressing portion 321 generally has an ergonomic design, such as an arc shape, to improve the transmission efficiency of the pressing force and the comfort of the user. The pressing portion 321 is designed such that a user can easily press the portion by a finger, thereby operating the adjustment assembly 3.

Referring to fig. 4, in the present embodiment, the elastic member 33 is a coil spring, one end of which is disposed on the first connecting member 31, and the other end of which is disposed on the second connecting member 32. As a common elastic member 33, a coil spring has good elasticity and durability, and can effectively store and release elastic potential energy. One end of the coil spring can be fixed on the first connecting piece 31 through a buckle or other mechanical modes, and the other end of the coil spring is also fixed on the second connecting piece 32, so that when the second connecting piece 32 is stressed, the spring can be compressed and store energy, and when the coil spring is released, the spring can be restored to the original state and push the pawl 311 of the first connecting piece 31 to reset.

Referring to fig. 6, in the present embodiment, the first clamping portion 11 is provided with a sliding slot 112, and the sheath 2 is slidably connected to the sliding slot 112. The sheath 2 is provided with a slide matching the chute 112 so that the sheath 2 can slide freely within the chute 112. The design of the chute 112 ensures that the sheath 2 always moves along a predetermined path during sliding, avoiding the phenomenon of deflection.

Referring to fig. 6, in the present embodiment, two side walls of the first clamping portion 11 are respectively provided with a sliding groove 112, and two side walls of the outer sheath 2 are respectively provided with a sliding block, wherein one sliding block corresponds to one sliding groove 112.

In this embodiment, in order to prevent the sheath 2 from being accidentally separated from the primary holding portion 11, an anti-separation structure is provided between the sheath 2 and the primary holding portion 11, and the anti-separation structure can prevent the sheath 2 from being separated from the jaw where the primary holding portion 11 is located in the longitudinal direction of the jaw body 1. As an alternative embodiment, the anti-falling structure includes an anti-falling groove 113 provided in the sliding groove 112, and an anti-falling protrusion 22 provided on the sliding block of the sheath 2, as shown in fig. 8, the anti-falling protrusion 22 is slidably connected in the anti-falling groove 113, so that the sheath 2 can freely slide in the sliding groove 112, and simultaneously limit the anti-falling protrusion through two ends of the anti-falling groove, thereby accurately controlling the displacement degree of the sheath 2 on the first clamping portion 11 and preventing the sheath from being separated from each other. As an alternative embodiment, the end wall of the chute 112 forms a drop-off prevention feature, which is located at the end of the chute 112 near the binding clip. When the user pulls the sheath 2 outwards, the portion of the sheath 2 will be held against the end wall, preventing further displacement thereof, and thus preventing the sheath 2 from disengaging from the primary gripping portion 11. This design is simple and efficient and reduces the need for additional components.

Referring to fig. 1, in this embodiment, the pliers body 1 includes two levers connected by a pivot, one end of the lever is a first clamping portion 11, and the other end of the lever has a handle, and when a hand force is applied to the two handles, the jaw portion (a position between the two first clamping portions 11) is closed, thereby realizing the function thereof.

Finally, it should be noted that, although the embodiments have been described in the text and the drawings, the scope of the application is not limited thereby. The technical scheme generated by replacing or modifying the equivalent structure or equivalent flow by utilizing the content recorded in the text and the drawings of the specification based on the essential idea of the application, and the technical scheme of the embodiment directly or indirectly implemented in other related technical fields are included in the patent protection scope of the application.
