Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a liver membrane dissection separator. Background Art

[0002] Tissue separator is one of the commonly used instruments in surgical operations, used to separate tissues so that surgeons can better observe and handle the surgical area, and can pull tissues so that surgeons can better operate and handle the surgical area. The existing tissue separation forceps are mainly composed of a stainless steel sheet structure, and the rear end pulls the four-bar hinge mechanism through the handle traction wire to control the opening and closing of the clamp, thereby achieving the purpose of pulling and separating tissues; because the four-bar hinge is relatively small, it is difficult to manufacture, but in the process of multiple pulling and separation, the four-bar hinge is easy to be damaged during use, and because the separator is relatively small, it is inconvenient to replace. Usually, after the four-bar hinge is damaged, the entire tissue separator needs to be replaced with a new four-bar hinge, which increases the production cost; and the tissue separator of the prior art, in order to avoid the clamp damaging human tissue during tissue traction and separation, but in the separation operation for the human liver membrane, the outer end of the clamp is set in an arc shape, and the outer wall of the clamp is easy to push against the liver membrane, pushing the already slippery liver membrane open, resulting in the inability to separate the liver membrane, affecting the surgical operation;

[0003] In summary, it is necessary to design a liver membrane dissection separator to solve the problems in the prior art that the tissue separator is easily damaged, has high production costs, and the outer side of the clamp is arc-shaped, which may lead to failure of liver membrane separation.

In this embodiment, the traditional arc clamp is abandoned and a clamping mechanism 1 is provided. The clamping mechanism 1 includes a clamp 101, a clamp 102 and an elastic element 103. The clamp 101 and the clamp 102 are arc clamps, and the front ends are hingedly mounted on a round rod provided at the front end of a shell 3. The outer wall is a smooth arc surface for facilitating the opening of the separated liver membrane. The outer side of the rear part is movably connected to the inner wall of the shell 3 through the elastic element 103, and the inner side of the rear part is fixedly connected to the traction mechanism 2:

[0031] In this embodiment, under normal conditions, the elastic element 103 pulls clamp 101 and clamp 102 to close clamp 101 and clamp 102. When clamp 101 and clamp 102 are stretched outward, the front ends of clamp 101 and clamp 102 first contact the liver membrane, and the handle 201 is held tightly to open clamp 101 and clamp 102 to separate the liver membrane. This solves the problem in the prior art that when the arc-shaped clamp is stretched outward to open the wind-force liver membrane, the front end contacts the liver membrane, and the two sides of the arc-shaped clamp first push the liver membrane open, resulting in separation failure.

When no external force is applied, the elastic element 103 tightens the clamp 1 101 and the clamp 2 102 to close the clamping mechanism 1.

[0034] When in use, the grip 201 is gripped and pressed, driving the Y-shaped traction rope 201 to move backward, pulling the rear ends of the clamp 101 and the clamp 2 102 closer together, and the front ends of the clamp 101 and the clamp 2 102 open, thereby stretching the liver membrane;

[0035] In this embodiment, a traction mechanism 2 is provided, which includes a handle 201 and a Y-shaped traction rope 201. The traditional four-bar hinge for controlling the opening and closing of the clamp is abandoned, and the Y-shaped traction rope 201 which is easy to replace and relatively cheap is used instead, so as to solve the problem in the prior art that the four-bar hinge in the tissue separator is easily damaged during repeated use and has high production cost.

[0036] In summary, the liver membrane dissection separator disclosed in the utility model comprises: a housing 3, a clamping mechanism 1, and a traction mechanism 2. In a normal state, the clamp 101 and the clamp 202 are clamped and closed, and the handle 201 is pressed by hand to drive the Y-shaped traction rope 201 to move backward in the housing 3, and the clamp 101 and the clamp 202 are controlled to open to separate the liver membrane;

[0037] A traction mechanism 2 is provided, and the traction mechanism 2 includes: a handle 201 and a Y-shaped traction rope 201. The traditional four-bar hinge is abandoned to control the opening and closing of the clamp, and the Y-shaped traction rope 201 which is easy to replace and relatively cheap is used instead, so as to solve the problem that the four-bar hinge in the tissue separator in the prior art is easy to be damaged during repeated use and the production cost is high;

[0038] An arc-shaped triangular clamp is provided. When the clamp 101 and the clamp 102 are closed, the clamp 101 and the clamp 102 are arc-shaped clamps, and the outer wall is a smooth arc surface for facilitating the opening and separation of the liver membrane. When opening outward, the front end of the clamp 101 and the clamp 102 first contacts the liver membrane, and the handle 201 is held tightly, and the clamp 101 and the clamp 102 are opened to separate the liver membrane, thereby solving the problem in the prior art that when the arc-shaped clamp opens the wind-force liver membrane outward, the front end contacts the liver membrane, and the two sides of the arc-shaped clamp first push the liver membrane open, resulting in separation failure.
