Among the figure: 1 fixed handle, 2 flexible handles, 3 back-moving springs, 4 fixed screws, 5 tooth plates, 6 clamps, 7 clamp fixed screws, 8 reseting pressuring springs, 9 stage clip fixed screws, 10, limit base, 11 steady pins, 12 rest pads, 13 set bolts, 14 irrigators, 15 claw beams, 16 pull bars, 17 stay rod pins, 18 are clamp, 19 active clamps, 20 clamp steady pins, 21 clamp connecting pins, 22 clamp plates fixedly.

The specific embodiment

Referring to Fig. 1-Fig. 2, this utility model is mainly by fixed handle 1, flexible handle 2, back-moving spring 3, tooth plate 5, clamp 5, reseting pressuring spring 8, limit base 10, rest pad 12, irrigator 14, claw beam 15, pull bar 16, fixedly clamp 18, active clamp 19 and clamp plate 22 are formed.

Fixed handle 1 is connected with flexible handle 2 usefulness steady pins 11 and can rotates; Article two, back-moving spring 3 compresses mutually, is connected and fixed on handle 1 and the flexible handle 2 with fixed screw 4 respectively, and has elasticity; Fixed handle 1 usefulness set bolt 13 is connected and fixed with rest pad 12 and is one; Tooth plate 5 is fixed on the fixed handle 1, and clamp 6 usefulness clamp fixed screws 7 are fixed on the flexible handle 2 and can rotate; Reseting pressuring spring 8 usefulness stage clip fixed screws 9 are fixed on the flexible handle 2 and withstand clamp 6, and clamp 6 has elasticity; Tooth plate 5 blocks identical mutually with clamp 6; Limit base 10 is welded on the flexible handle 2; Claw beam 15 and irrigator 14 are fixed on the rest pad 12.

One side of movable binding clip 19 1 ends is fastened on the fixed pliers head 18 with clamp connecting pin 21 and can rotates, being fastened on clamp steady pin 20 on one side can be movable on the pull bar 16, and the other end of movable binding clip 19 and the fixed pliers head 18 identical folder pins that form are sewed up binding clip; Be welded with clamp plate 22 on fixed pliers head 18 and the movable binding clip 19, this clamp plate 22 is a hard clamp plate, strengthens the hardness of sewing up binding clip.

One end of pull bar 16 penetrates claw beam 15 and rest pad 12, is inserted in flexible handle 2 usefulness stay rod pins 17 and is connected and fixed, and the other end is connected with movable binding clip 19; The pincers tail of fixed pliers head 18 is fixed on the claw beam 15.As long as at this moment hold handle with a firm grip, tooth plate 5 and clamp 6 chucking that under the effect of reseting pressuring spring 8, coincide mutually, flexible handle 2 pulling pull bars 16, pull bar 16 pulling active clamps 19, active clamp 19 and fixedly clamp 18 coincide sting tight; Decontrol handle, press clamp 6, under the effect of two back-moving springs 3, clamp opens and resets.

In the operation application process, decontrol handle, tooth plate 5 and clamp 6 are under the effect of reseting pressuring spring 8, and binding clip is still stung tight sewing needle, and the healthcare givers carries out operation stitching in the human abdominal cavity under the situation of direct-view; And by irrigator 14, can inject in the claw beam 15 with disinfectant solution, the sterilization of flushing residual liquid, folder pin stitching clamp is that metal is made, and also can use high-temperature sterilization.

Direct-view described in the utility model Wicresoft is meant in surgical procedures, for the more accurate focus of more clearly looking at straight, with the more small wound and the direct visual field, undergos surgery.And this utility model is the needle holder that is exclusively used in the direct-view Minimally Invasive Surgery.
