Direct-view Wicresoft ligaturing forceps

Technical field

This utility model relates to a kind of ligaturing forceps, and particularly a kind of direct-view Wicresoft ligaturing forceps is exclusively used in the ligaturing forceps of inside of human body operation stitching, belongs to medical instruments field.

Background technology

Traditional surgical operation generally all will cut otch one on patient's skin and flesh, short then 6-10 centimetre, long then 10-15 centimetre or longer.In the human body minimal invasive surgical procedures, in case in the human body body, find focus, need excision, in inadvertent closure, organ needs to sew up in the body, stitching thread needs knotting in sewing process, prior art: the one, in operation process, need in the human body body, carry out pneumoperitoneum, and make operation that certain space be arranged; The 2nd, tie a knot with general pincers, the operation trouble, knotting speed is slow, does not satisfy ideal surgical effect.

Summary of the invention

The purpose of this utility model is to overcome existing the problems referred to above in the prior art, and a kind of reasonable in design, direct-view Wicresoft ligaturing forceps that wound is little are provided.

The technical scheme that its technical problem that solves this utility model adopts is: this direct-view Wicresoft ligaturing forceps comprises fixed handle, flexible handle, back-moving spring, rest pad, pull bar, draw-bar seat, claw beam, active clamp, fixedly clamp, rotator, bearing holder (housing, cover), bearing block, fixture block and irrigator, it is characterized in that: on described fixedly clamp and adjustable clamp, have the knotting hook, on described flexible handle, have pull rod slot, be positioned at this pull rod slot with the fixed draw-bar seat of pull bar.

Knotting hook described in the utility model is opened in the fixing corner of clamp and adjustable clamp.

This utility model compared with prior art its beneficial effect is: reasonable in design, only need to cut 2-3 centimetre, use special-purpose drag hook that otch is stretched, the cold light source light beam is focused in the human body body by light guide bundles, both can make operative doctor clearly directly see each position in the body clearly, and lower infected danger again because of otch is little.Good operation effect, safety easy to use.

Among the figure: 1 fixed handle, 2 flexible handles, 3 back-moving springs, 4 steady pins, 5 rest pads, 6 pull rod slot, 7 pull bars, 8 draw-bar seats, 9 claw beams, 10 active clamps, 11 are clamp, 12 knotting hooks, 13 steady pins, 14 connecting pins, 15 rotator, 16 bearing holder (housing, cover)s, 17 bearing blocks, 18 fixture blocks, 19 bearings, 20 set bolts, 21 irrigators fixedly.

The specific embodiment

Referring to Fig. 1-Fig. 3, this utility model is mainly by fixed handle 1, flexible handle 2, back-moving spring 3, rest pad 5, pull bar 7, draw-bar seat 8, claw beam 9, active clamp 10, fixedly clamp 11, rotator 15, bearing holder (housing, cover) 16, bearing block 17, fixture block 18 and irrigator 21 are formed.

Fixed handle 1 of the present utility model is connected with rest pad 5 and fuses, fixed handle 1 is connected with flexible handle 2 usefulness set bolts 20 and can rotates, article two, back-moving spring 3 compresses mutually, is fixed on fixed handle 1 and the flexible handle 2 with steady pin 4 respectively, and has elasticity; Flexible handle 2 is one with pull rod slot 6.Rotator 15 is fixed on the bearing block 17, and claw beam 9 penetrates rotator 15 and is fixed on the bearing block 17, and two bearings 19 are inserted in bearing block 17, and bearing holder (housing, cover) 16 and bearing block 17 tighten and be fixed on the rest pad 5 mutually; It is fixing that one end of fixture block 18 snaps in bearing holder (housing, cover) 16, and an end is fixed on the rest pad 5; Irrigator 21 is fixed on the rotator 15.Fixedly an end of clamp 11 and active clamp coupling is coincide and is formed binding clip, and the other end of active clamp 10 is fixed on fixedly on the clamp 11 with steady pin 13 on one side and can rotates, and another side is fixed on the pull bar with connecting pin 14 and can rotates; Fixedly clamp 11 and active clamp 10 are 90 degree bendings; Knotting hook 12 is opened in the fixing corner of clamp 11 and active clamp 10, is exclusively used in the hook line of tiing a knot.One end of pull bar 7 is connected with active clamp 10, and the other end and draw-bar seat 8 are fixing; Pull bar 7 penetrates claw beam 9, passes rotator 15, bearing block 17 and rest pad 5; Draw-bar seat 8 is inserted in pull rod slot 6 and coincide fixing; Fixedly the afterbody of clamp 11 and claw beam 9 are connected and fixed.

Rot 15 of the present utility model is connected and fixed with claw beam 9, and can rotate by 360 degree, and under direct field of vision, ligaturing forceps inserts in the human body body, sews up the position of knotting as required, adjusts the direction of active clamp 10.Irrigator 21 is installed in rotator 15, when disinfectant solution injects irrigator 21, can wash claw beam 9 interior human body residual liquids and manage interior sterilization, also can use high-temperature sterilization.

During use, as long as hold fixed handle 1 and fixed handle 2 with a firm grip, pull rod slot 6 pulling pull bars 7, pull bar 7 pulling active clamps 10, active clamp 10 and fixedly clamp 11 coincide sting tight; Decontrol fixed handle 1 and fixed handle 2, under the effect of two back-moving springs 3, active clamp 10 and fixedly clamp 11 reset.

Direct-view described in the utility model Wicresoft, be in operation process without pneumoperitoneum, under direct-view, undergo surgery, certain space need not arranged in the human body body.And direct-view Wicresoft ligaturing forceps is to be exclusively used in the direct-view Minimally Invasive Surgery, and the human body intracorporeal organ needs to sew up in the body, the knotting special vice that stitching thread need be tied a knot in sewing process.
