Description

Sew up nipper

Technical field

This utility model relates to a kind of stitching nipper, is used for human body intracorporeal organ tissue cut and grasps the location so that sew up, and belongs to medical instruments field.

Background technology

In human body, open in the abdomen operation, need internal organ-tissue otch to grasp the location so that sew up.Prior art does not have special-purpose apparatus forceps class, substitutes with general instruments pincers class the organ-tissue otch is grasped the location.General instruments pincers class operation is used and is not matched, and easily causes the organ-tissue damage, does not satisfy ideal surgical effect.

The utility model content

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and the stitching nipper of a kind of reasonable in design, good operation effect is provided.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of stitching nipper is characterized in that: comprise fixed handle, flexible handle, rotator, fixed cover, bearing holder (housing, cover), fixture block, claw beam, pincers seat, clamp, pull bar; Fixed handle and flexible handle are rotationally connected; The rotator suit is fixed on the fixed cover; Fixture block is fixedlyed connected with bearing holder (housing, cover) with fixed handle respectively; Bearing holder (housing, cover) is sleeved on the fixed cover; Claw beam one end and fixed cover are fixed, and the other end is fixing with the pincers seat; Clamp is rotatably connected on the pincers seat; Pull bar one end and flexible handle are rotationally connected, and the other end and clamp are rotationally connected; Clamp comprises clamp and following clamp, and last clamp and following clamp cooperate.

This utility model have on the last clamp waist shape release groove and on circular release groove.

Have down waist shape release groove and following circular release groove on this utility model infra clamp.

This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, can not damage organ-tissue in grasping the location, operation is used convenient, effective.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is that the A of clamp of Fig. 1 is to the partial structurtes sketch map.

Fig. 3 is this utility model embodiment partial structurtes sketch maps.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.

Embodiment: referring to Fig. 1～Fig. 3, fixed handle 1 and flexible handle 2 are rotationally connected.

Article two, back-moving spring 3 compresses mutually, is separately fixed on fixed handle 1 and the flexible handle 2, and has elasticity.Tooth bar 5 is fixed on the flexible handle 2.A back-moving spring 3 withstands on the tooth bar 5, makes tooth bar 5 have elasticity.Have latch 6 on fixed handle 1, tooth bar 5 coincide with latch 6 couplings.Fixed handle 1 and flexible handle 2 as long as hold with a firm grip, tooth bar 5 and latch 6 tighten automatically under the effect of back-moving spring 3; Press tooth bar 5, fixed handle 1 and flexible handle 2 automatically reset under the effect of back-moving spring 3.

Rotator 14 suits are fixed on the fixed cover 8.Fixture block 13 is fixedlyed connected with bearing holder (housing, cover) 4 with fixed handle 1 respectively.Bearing holder (housing, cover) 4 is sleeved on the fixed cover 8, between bearing holder (housing, cover) 4 and fixed cover 8 bearing is installed.Flushing hole 15 is fixed on the rotator 14, can wash the residual liquid sterilization with disinfectant solution, also can use high-temperature sterilization.

Claw beam 7 one ends and fixed cover 8 are fixing, and the other end is fixing with pincers seat 16.Clamp 9 is rotatably connected on the pincers seat 16.Pull bar 11 1 ends pass fixture block 13, rotator 14, fixed handle 1 back and flexible handle 2 and are rotationally connected, and the other end and clamp 9 are rotationally connected.

Open in the abdomen operation process in that human body intracorporeal organ tissue cut is grasped localized direct-view, rotator 14 can drive clamp 9 and do 360 degree rotations, improves its effect, reaches the multifunctionality of application.

Have folder tooth 19 on clamp 9, folder tooth 19 is harmless folder tooth.Clamp 9 comprises clamp 10 and following clamp 12, and last clamp 10 and following clamp 12 cooperate.Have on the last clamp 10 waist shape release groove 17 and on circular release groove 18, have down waist shape release groove and time circular release groove on the infra clamp 12.When

last clamp

10 and 12 clampings of following clamp, the middle part of clamp 9 forms a cavity 20.

The organ-tissue otch grasps localized direct-view and opens in the abdomen operation process in to human body, clamp 9 grasps the organ tissue cut, can not damage under the effect of folder tooth 19 waist shape release groove 17 on the organ-tissue, on circular release groove 18, down waist shape release groove, the art designs of circular release groove down, it is littler to make clamp 9 grasp area, residual liquid can flow out from four release grooves in the human body body, and the organ-tissue damage is littler.The art designs of cavity 20, clamp 9 grasps in the organ tissue cut, and incision at cavity 20 positions, can arbitrarily not damaged just.
