Detailed Description

The technical solution in the embodiment of the present invention will be described below with reference to the drawings in the embodiment of the present invention.

Firstly, relevant definition:

the near end is the near end and the far end is the far end.

The upper and lower limiting refers to cross limiting in the upper and lower directions; wherein the up-down direction refers to a direction perpendicular to the relative motion direction of the two clip sides of the aneurysm.

II, the working principle is as follows:

when the surgical clip is in an initial state, under the action of elastic force of the elastic element, the two clamping arms of the aneurysm clip are in parallel contact and have initial pretightening force, and the object clamping sides of the two clamping arms are in a closed state and face to each other.

When the surgical clip is in a working state, the clip application forceps clip the operating ends of the two clamping arms of the surgical clip and apply acting force to the operating ends, so that the clamping ends of the two clamping arms of the surgical clip are forced to open, and the purpose of clamping and clamping objects is achieved.

In the process of opening the clamping ends of the two clamping arms of the surgical clamp, the limiting pin shaft is always positioned in the limiting groove, so that the limiting grooves of the two clamping arms are forced to be vertically crossed and attached together, the situation of dislocation of the two clamping arms can be effectively prevented, and the situation of untight foreign matter clamping is avoided.

Thirdly, working process:

as shown in figure 1, when the clamp application forceps continuously apply pressure to the surgical clamp to clamp a clamped object, the clamp application forceps are released, the surgical clamp is clamped on the clamped object, and due to the resilience force of the elastic element, the angle of the clamping end of the surgical clamp is continuously reduced, so that the clamped object is gradually and stably clamped until the clamped object is completely clamped. At the moment, the limiting pin shaft is finally fixed at a position after sliding in the limiting groove of the limiting part, the limiting pin shaft stops moving, and meanwhile, the rotating motion of the clamping arm around the elastic element also stops correspondingly, so that the limiting effect of the motion of the clamping arm is achieved.

The clamping ends of the two clamping arms of the surgical clamp are continuously opened along with continuous pressure applied to the surgical clamp by the clamp application forceps, at the moment, the limiting pin shaft continuously slides in the limiting groove of the limiting part, when the limiting pin shaft slides to the end part of the limiting groove, the movement of the limiting pin shaft is limited, the movement range of the limiting pin shaft reaches the limit, the limiting pin shaft stops moving, and meanwhile, the rotary movement of the clamping arms around the elastic element also correspondingly stops, so that the limiting effect of movement of the clamping arms is achieved.

specifically, the structure has two parallel structures:

wherein the elastic element is an elastic element, such as a spring with 1.5 turns or other elastic wire, plate material, etc.

Structure 1: the limiting part comprises a first limiting groove arranged at the far end of the operating end of the first clamping arm, a second limiting groove arranged at the far end of the operating end of the second clamping arm and a movable limiting pin shaft.

The end part of the limiting pin shaft sliding in the first or second limiting groove is a structure with a flanging, a bolt, a nut or other step-shaped limiting structures, and one of the following concentrated conditions is adopted:

11) the limiting pin shaft is a pin shaft and is arranged on the structure of flanging at two ends of the pin shaft:

the limiting pin shaft clamps the two clamping arms in the vertical direction through the pin shaft and flanges at two ends of the pin shaft; the surgical clamp is provided with a sunken area which is used for enabling the end surface position of the limiting pin shaft to be lower than the contour surface of the clamping arm on a plane perpendicular to the motion planes of the two clamping arms. The effective length of the pin shaft is larger than the distance between the two clamping arms in the vertical direction (the vertical direction refers to the direction vertical to the motion plane of the two clamping arms), namely, allowance for enabling the limiting pin shaft to slide in the first limiting groove and the second limiting groove is reserved.

12) The limiting pin shaft is of a bolt and nut matched structure:

the end part of the bolt and the nut form a limiting and fixing structure, and the two clamping arms are arranged between the end part of the bolt and the nut; the surgical clamp is provided with a sunken area, and the end surface position of the limiting pin shaft is lower than the contour surfaces of the two clamping arms of the surgical clamp. The length of a bolt column between the nut and the bolt is larger than (the distance between the two clamping arms in the vertical direction and the distance between the two clamping arms in the vertical direction of the nut), namely, a margin for enabling the limiting pin shaft to slide in the limiting groove is reserved.

13) In the same way, the limiting pin shaft is a pin shaft structure with one end part turned over and the other end part matched with the nut;

the end part of the nut and the flanging form a limiting and fixing structure, and the two clamping arms are arranged between the end part of the nut and the flanging; the surgical clamp is provided with a sunken area which is used for enabling the end surface position of the limiting pin shaft to be lower than the contour surface of the clamping arm on a plane perpendicular to the motion planes of the two clamping arms.

21) when the two clamping arms are provided with the limiting grooves, the limiting pin shaft slides in the first limiting groove and the second limiting groove simultaneously, and the object clamping side opening position is kept to form a symmetrical structure by taking the axis of the surgical clamp as a central line. The reason for realizing the symmetrical opening is that the clamp is in a symmetrical structure, so when external force is applied to the clamping end by the application clamp, the opening position of the clamping end can automatically keep symmetrical.

22) When a single clamping arm is provided with a limiting groove, the limiting pin shaft is fixed on one clamping arm, and when the limiting pin shaft slides in the limiting groove of the other clamping arm, the object clamping side opening position is kept to form a symmetrical structure by taking the axis of the surgical clamp as the center line. (symmetric opening is realized because the clamp has a symmetric structure, so when external force is applied to the clamping end by using the clamp, the opening position of the clamping end can automatically keep symmetric)

Example three: the limit pin shaft slides in the limit groove and comprises two conditions:

31) when the surgical clip is used, the opening angles of the two clamping arms, namely the opening angles of the clamping ends of the surgical clip, are set according to the diameters of clamped objects, and the synchronous automatic sliding of the limiting pin shaft in the first limiting groove and the second limiting groove is accompanied.

32) When the surgical clip is used, the opening angles of the two clamping arms, namely the opening angles of the clamping ends of the surgical clip, are set according to the diameters of clamped objects, and the synchronous automatic sliding of the limiting pin shaft in the limiting groove on one side is accompanied.
