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 operation process,, need excision in case find focus in the human body body, in inadvertent closure, intracorporeal organ need separate searches lesions position, and prior art is to carry out pneumoperitoneum in the human body body, make operation that certain space be arranged, search lesions position with the common separation pincers.Its defective is usefulness pneumoperitoneum operation, and operating time is long, and it is slow that patient feels bad wound healing, if the weak wound healing effect of patient body is just poorer; The 2nd, common separation pincers application point limits to some extent, 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 right angle elastic separating plier that wound is little are provided.

The technical scheme that its technical problem that solves this utility model adopts is: this direct-view Wicresoft right angle elastic separating plier comprises fixed handle, flexible handle, active clamp, fixedly clamp, bearing holder (housing, cover), bearing block, pull bar, rotator, claw beam and irrigator, described active clamp and fixedly clamp be right angle forceps, it is characterized in that: also be provided with back-moving spring, rest pad, pull rod slot, draw-bar seat and fixture block, described back-moving spring is installed between fixed handle and the flexible handle, rest pad and fixed handle fuse, and pull rod slot is opened on flexible handle; One end of described pull bar is connected with active clamp, and the other end and draw-bar seat are fixed; Draw-bar seat is inserted in pull rod slot and coincide fixingly, and an end of fixture block snaps in bearing holder (housing, cover) and fixes, and the other end is fixed on the rest pad.

Back-moving spring described in the utility model has two, and they compress mutually, and is fixed on described fixed handle and the flexible handle with steady pin respectively.

This utility model compared with prior art its beneficial effect is: reasonable in design, and safe in utilization, effective; 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.

Fig. 2 is the structure for amplifying sketch map (when closing up) at A place among Fig. 1.

Fig. 3 is the elevational schematic view of Fig. 2.

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 poor, the 13 active clamp steady pins of clamp, 12 clamps, 14 active clamp 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.Active clamp 2 wherein and fixedly clamp 1 be right angle forceps.

Fixed handle 1 of the present utility model fuses with rest pad 5, and 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 the other end is fixed on the rest pad 5; Irrigator 21 is fixed on the rotator 15.Fixedly to be provided with clamp poor 12 for clamp 11 and active clamp 10, and the binding clip of active clamp 10 is with fixedly clamp 11 couplings are identical; The pincers tail of active clamp 10 is fixed on fixedly on the clamp 11 with active clamp steady pin 13 on one side and can rotates, and another side is fixed on the pull bar 7 with active clamp connecting pin 14 and can rotates.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, and passes rot 15, bearing block 17 and rest pad 5; Draw-bar seat 8 is inserted in pull bar 6 grooves and coincide fixing.Fixed handle 1 and fixed handle 2 as long as at this moment hold 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.Between fixed handle 1 and the flexible handle 2 back-moving spring 3 is installed, as long as hold fixed handle 1 and flexible handle 2 with a firm grip, active clamp 10 will clamp, release handle, and fixed handle 1 and flexible handle 2 automatically reset under the effect of back-moving spring 3.

During use, can carry out the focus search to the human body intracorporeal organ, separate the bonding of intracorporeal organ, reach the purpose of operation with this utility model.Promptly can rotate by 360 degree, the right angle elastic separating plier is inserted in the human body body,, adjust the direction of binding clip, improve its effect, reach the multifunctionality of application according to the human body intracorporeal organ of need search by rotator 15.

Direct-view described in the utility model Wicresoft is meant in operation process to undergo surgery under direct field of vision without pneumoperitoneum certain space not to be arranged in the human body body.And direct-view Wicresoft right angle elastic separating plier is to be exclusively used in the direct-view Minimally Invasive Surgery, carries out the focus search in the human body body, according to the search angle of intracorporeal organ, uses the right angle elastic separating plier intracorporeal organ is separated, and these pincers are the isolating special vices of intracorporeal organ.
