Illustratively, the first connector 14 is a circular ring structure, and the first conduit 24 is sealable to plug into the circular ring structure.
As shown in fig. 6 to 15, the endoscope 8 is fixed inside the puncture needle 1 by a support 7, wherein the support 7 comprises an arc-shaped bending part 75, a left abutting part 71, a right abutting part and a groove 751 for placing the endoscope 8 is formed on one surface of the arc-shaped bending part 75;
The arc-shaped bent portion 75 is elastically deformable, and the left abutting portion 71 and the right abutting portion 72 are abutted against the inner wall of the puncture needle 1 by the force generated by the deformation of the arc-shaped bent portion 75. The support 7 of the present invention may be made of, for example, polytetrafluoroethylene (PTFE), polyethylene (PE), polypropylene (PP), rubber (RU), etc.
The left abutting portion 71 includes a left arc segment 711, a left horizontal segment 712, and a left vertical segment 713, the radius of curvature of the left arc segment 711 is substantially identical to the radius of curvature of the inner wall of the puncture needle 1, and the right abutting portion 72 includes a right arc segment 721, a right horizontal segment 722, and a right vertical segment 723, the radius of curvature of the right arc segment 721 is substantially identical to the radius of curvature of the inner wall of the puncture needle 1. The support 7 further includes a front stopper 73 for restricting the front end position of the endoscope 8 and a rear stopper 74 for restricting the rear end position of the endoscope 8.
The left abutting portion 71 has a structure with a small top and a large bottom, and the right abutting portion 72 has a structure with a small top and a large bottom. As shown in fig. 8, the above structure allows the support 7 to be firmly fixed to the inside of the puncture needle 1.

The left abutting portion 71 and the right abutting portion 72 are thereby firmly abutted against the inner wall of the puncture needle 1 by the elastic force.
As shown in fig. 6 to 9, an illumination light source and a camera head are formed on the endoscope 8. The endoscope 8 is of a conventional structure and will not be described in detail herein.
As shown in Figs. 1-15, the needle 11 of the puncture needle 1 of the present invention has a diameter of 1.6-2.0mm, and may be 1.8mm in particular, and the needle 11 has a length of 60-80mm. When the endoscope 8 is installed, the endoscope 8 is placed in the groove 751 of the support 7, the limit of the endoscope 8 can be conveniently carried out through the front baffle and the rear baffle, and the support 7 is extruded and deformed by medical forceps or forceps, so that the support 7 and the endoscope 8 are pushed to the position of the puncture needle 1 close to the opening together. When the puncture needle 1 is used, the position can be observed in real time through the endoscope 8, so that the risk to the heart is avoided.
The endoscope 8 is integrated in the puncture needle 1, so that small wounds are generated, and the postoperative recovery of a patient is facilitated. Simultaneously, the endoscope 8 is firmly fixed in the puncture needle 1 through the support piece 7, so that the shaking of the endoscope 8 during puncture is avoided, and the operation of doctors is influenced. By means of the elasticity of the support 7 and the structural arrangement of the left abutment 71 comprising the left arc segment 711, the left horizontal segment 712 and the left vertical segment 713, and the right abutment 72 comprising the right arc segment 721, the right horizontal segment 722 and the right vertical segment 723, a stable position locking can be achieved without the need for a Y-or T-shaped support structure as usual, thereby reducing the space occupied by the support, leaving sufficient effusion extraction space at the opening, reducing the possibility of pericardial effusion blockage while reducing the wounds.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes may be made and equivalents may be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
