Description
Technical field
This utility model relates to a kind of wolf tooth nipper, is used for the organ-tissue of pathological changes in the human body and flesh stayed to undergo surgery tearing up and excising, 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 wolf tooth 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 wolf tooth 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; Have at the head of last clamp and to press from both sides tooth, the head of infra clamp has down the folder tooth, on press from both sides tooth and down the folder tooth cooperate.
This utility model all has release groove on last clamp and following clamp.
This utility model compared with prior art has following advantage and effect: 1, reasonable in design; 2, tear up and excise the organ-tissue that grasps pathological changes and flesh being stayed undergo surgery, can not damage other healthy organ tissues, operation use make things convenient for, 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 that the B of clamp of Fig. 1 is to the partial structurtes sketch map.
Fig. 4 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. 4, 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.
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.
Clamp 9 comprises clamp 10 and following clamp 12, and last clamp 10 and following clamp 12 cooperate.Have folder tooth 17 at the head of last clamp 10, the head of infra clamp 12 has down folder tooth 18, on press from both sides tooth 17 and down 18 interlocks of folder tooth cooperate, on press from both sides tooth 17 and press from both sides tooth 18 down and be the wolf tooth profile of tooth.
On last clamp 10 and following clamp 12, all have release groove 19.
In to human body the organ-tissue of pathological changes and flesh stay undergo surgery tear up with resection operation in, the wolf tooth profile of tooth go up folder tooth 17 and down folder tooth 18 organ-tissue and the flesh that grasp pathological changes stay firmly, tear up and excise firmly effective, can not damage other health tissues.The effect of release groove 19 is in extracting is torn up and excised, and can discharge by residual liquid.
