Description

Myoma grasping forceps

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a myoma nipper is related to.

Background

The myoma grasping forceps are tools for laparoscopic myoma removal, the existing laparoscopic surgery is small in wound and fast in recovery, the myoma is widely applied to clinic, the myoma is a frequently encountered disease and is mostly benign, and the hysteromyoma patient is very wide in hysteromyoma removal reserved surgery. The myoma grasping forceps realize the purpose of grasping and stripping the hysteromyoma by separating the occlusion of the fixed forceps clip and the movable forceps clip. The existing uterine fibroid grasping forceps have the following problems: 1. the tooth portion of binding clip is shorter, and it is relatively poor to insert the nature, easy slippage, to the myoma that needs certain dynamics to strip than fixed, has the slippage many times, probably has the vice condition such as damage, increase operation time. 2. For deep myoma, because the binding clip is the crew cut structure, it is comparatively inconvenient to snatch the myoma.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art not enough, provide a myoma nipper.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a myoma grasping forceps comprises a fixed forceps clip and a movable forceps clip which are connected in a rotating way, and a forceps body which is fixedly connected with one end of the fixed forceps clip, locate the fixed binding clip that the pincers body kept away from fixed binding clip one end, keep away from the movable binding clip that fixed binding clip one end rotation is connected with the pincers body, the pivot department that movable binding clip is connected with the pincers body is equipped with the torsional spring that resets movable binding clip, fixed binding clip and movable binding clip are crooked arcuation structure, fixed binding clip and pincers body are on same straight line, be equipped with first gyro wheel on the movable binding clip, first gyro wheel rotates with fixed binding clip to be connected, the one end that movable binding clip is close to the pincers body articulates there is the connecting rod, be equipped with waist shape hole in the connecting rod, be equipped with the fixed block in the pincers body, the fixed block passes waist shape hole and is connected with the connecting rod rotation, be fixed with wire rope between the one end that movable binding clip was kept away from to the connecting rod and the first gyro wheel, when the connecting rod rotates to the level, movable binding clip and fixed binding clip can interlock each other.

And a second roller is further arranged in the fixed clamp, the second roller is in meshing transmission with the first roller, a third roller is arranged in the clamp body, and the steel wire rope is positioned at the axis of the clamp body after being guided by the third roller and the second roller.

Spring pieces are fixed on the opposite surfaces of the fixed jaw and the movable jaw.

The utility model has the advantages that: the clamp head is set to be of an arc-shaped structure, myoma is conveniently clamped, the length of the clamp head is lengthened by the arc-shaped fixed clamp head and the arc-shaped movable clamp head, the embedding performance of the clamp head is better, and the myoma is fixed and is not easy to slip.

in the figure: the clamp comprises a fixed clamp 1, a movable clamp 2, a spring piece 3, a first roller 4, a clamp body 5, a fixed clamp head 6, a movable clamp head 7, a torsion spring 71, a second roller 8, a steel wire rope 9, a connecting rod 10, a waist-shaped hole 11, a fixed block 12 and a third roller 13.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 3, the myoma grasping forceps comprises a fixed forceps jaw 1 and a movable forceps jaw 2 which are rotatably connected, a forceps body 5 fixedly connected with one end of the fixed forceps jaw 1, a fixed forceps head 6 arranged at one end of the forceps body 5 far away from the fixed forceps jaw 1, and a movable forceps head 7 rotatably connected with one end of the forceps body 5 far away from the fixed forceps jaw 1, wherein a torsion spring 71 for resetting the movable forceps head 7 is arranged at a rotating shaft where the movable forceps head 7 is connected with the forceps body 5, spring leaves 3 are fixed on opposite surfaces of the fixed forceps jaw 1 and the movable forceps jaw 2, after the operation is finished, the movable forceps jaw 2 is released, the spring leaves 3 serve the movable forceps jaw 2, and the torsion spring 71 resets the movable forceps head 7;

the fixed binding clip 6 and the movable binding clip 7 are of curved arc-shaped structures, when the fixed binding clip 6 and the movable binding clip 7 are meshed, the tip ends of the fixed binding clip 6 and the movable binding clip 7 are matched to form an arc-shaped plane, myomas are clamped by the tip ends of the fixed binding clip 6 and the movable binding clip 7 and are sleeved in the arc-shaped plane, the myomas can be well grabbed, the operation is convenient, the length of the binding clip is lengthened by the arc-shaped fixed binding clip 6 and the arc-shaped movable binding clip 7, so that the embedding performance of the binding clip is better, and the myomas is not easy to slip after being fixed; the fixed forceps holder 1 and the forceps body 5 are on the same straight line, the movable forceps holder 2 is provided with a first roller 4, the first roller 4 is rotatably connected with the fixed forceps holder 1, one end of the movable forceps head 7, which is close to the forceps body 5, is hinged with a connecting rod 10, a waist-shaped hole 11 is arranged in the connecting rod 10, a fixed block 12 is arranged in the forceps body 5, the fixed block 12 is rotatably connected with the connecting rod 10 after penetrating through the waist-shaped hole 11, a steel wire rope 9 is fixed between one end of the connecting rod 10, which is far away from the movable forceps head 7, and the first roller 4, a rotating shaft at the hinged part of the fixed block 12, the movable forceps head 7 and the forceps body 5 is positioned at the axis of the forceps body 5, when the movable forceps holder 2 rotates, the first roller 4 is driven to rotate, so that the right end of the steel wire rope 9 is wound on the first roller 4, the left end of the steel wire rope 9 drives the connecting rod 10 to rotate and move rightwards, so that after the movable forceps head 7 rotates, when the connecting rod 10 rotates to be horizontal, the movable forceps head 7 is engaged with the fixed forceps head 6, the separation distance between the movable tong head and the fixed tong head is not too large.
