Abstract

The utility model relates to direct-vision minimally-invasive object taking forceps specially used for taking out stones in human bodies. The forceps comprise a fixed forceps holder, a movable forceps holder, a forceps rod, a push rod, a movable handle, a clamping spring, a fixed handle, a washing piece, stone taking bowls, a rotator, a fixing sleeve, a steel ball, a steel ball positioning piece, a connecting sleeve, a rotating body and a push rod seat, and is characterized in that the bowl-shaped stone taking bowls are formed on both the fixed and the movable forceps holders; and when the two forceps holders are folded, the peripheries thereof are closed, and an ellipse is formed in the middle of the two forceps holders. The forceps have the advantages of reasonable structural design, bowl-shaped forceps holder, effective grasping and taking of stones in the abdominal cavities of the human bodies, good object taking effect, and convenient and safe surgical use.

Description

The thing pincers are got by direct-view Wicresoft

Technical field

This utility model relates to a kind of pincers, and the thing pincers are got by particularly a kind of direct-view Wicresoft, and it is exclusively used in the taking-up to the inside of human body calculus, belongs to technical field of medical instruments.

Background technology

In in direct-view Wicresoft peritoneoscope human abdominal cavity, performing the operation, need be to finding calculus in the human abdominal cavity, need to take out, prior art: carry out horsestone with general pincers and take out, its defective is: the intraperitoneal calculus has granular pattern, and granule varies, and general pincers carry out horsestone, gravelstone easily comes off, and Da Shi easily presss from both sides broken; Particularly cholelithiasis has the granular pattern calculus, and the mud type calculus is also arranged, with general pincers more difficulty get stone, and operating time is long, the operation trouble.

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 a kind of reasonable in design is provided, and calculus grasps effective direct-view Wicresoft and gets the thing pincers.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this direct-view Wicresoft gets thing pincers and comprises fixedly clamp, active clamp, claw beam, push rod, flexible handle, jump ring, fixed handle, rinse piece, gets stone bowl, rotator, fixed cover, steel ball, steel ball spacer, adapter sleeve, rotary body and draw-bar seat, it is characterized in that: what all have bowl-type on described fixedly clamp and active clamp gets the stone bowl, sealing around when two clamps close up, the centre of two clamps is ellipsoid.

This utility model compared with prior art has following positive effect: reasonable in design, and clamp is bowl-type, and the calculus that can carry out effectively in the human abdominal cavity grasps, and gets effective, the safety easy to use of performing the operation of thing.

Description of drawings

Fig. 1 is a structural representation front view of the present utility model.

Structural representation when Fig. 2 closes up for A place among Fig. 1.

Among the figure: 1 fixedly stone bowl, 12 rotator, 13 fixed covers, 14 steel balls, 15 steel ball spacers, 16 adapter sleeves, 17 rotary bodies, 18 clamp steady pins, 19 connecting pins, 20 draw-bar seats, 21 pull rod slot are got in clamp, 2 active clamps, 3 claw beams, 4 push rods, 5 hold-down screws, 6 flexible handles, 7 hold-down screws, 8 jump rings, 9 fixed handles, 10 flushing holes, 11.

The specific embodiment

Referring to Fig. 1-Fig. 2, fixed handle 9 of the present utility model is connected with flexible handle 6 usefulness hold-down screws 5, can rotate; Flexible handle 6 is one with pull rod slot 21; Article two, an end of jump ring 8 is fixed on fixed handle 9 and the flexible handle 6 with handle hold-down screw 7, and the other end withstands mutually, has elasticity.

Claw beam 3 is fixing with rotary body 17 welding, and rinse piece 10 is fixed on the rotator 12; Rotator 12 is inserted in fixed cover 13 and is inserted in claw beam 3, with steel ball 14 be pressed in rotator 12 and rotary body 17 on one side between after, rotator 12 is fixed on the claw beam 3; The another side of rotary body 17 also is inserted in steel ball 14 usefulness steel ball spacers 15 and is fixed, and compresses with adapter sleeve 16; The outer ring of adapter sleeve 16 is fixed on the fixed cover 13, and inner ring is fixed on the fixed handle 9.

Fixedly clamp 1 and active clamp 2 have the symmetrical stone bowl 11 of getting, and active clamp 2 lower ends are fixed on fixedly on the clamp 1 with clamp steady pin 18 on one side, and another side is fixed on the push rod 4 with connecting pin 19.

One end and the active clamp 2 of push rod 4 are connected and fixed, and an end has draw-bar seat 20; Push rod 4 penetrates claw beam 3, passes rotator 12, rotary body 17 and fixed handle 1, and it is identical fixing that draw-bar seat 20 is inserted in pull rod slot 21, and fixedly the afterbody of clamp 1 and claw beam 3 are connected and fixed.As long as at this moment hold handle with a firm grip, flexible handle 6 pulling push rods 4, push rod 4 pulling active clamps 2, binding clip closure; Decontrol handle, binding clip opens under the effect of jump ring 8.

Above-described annexation forms gall stone-removing clippers.

Push rod 4 of the present utility model is promote to clamp in the clamping process of clamp, and the promotion of push rod 4 is from flexible handle 6, the effect of flexible handle 6: the one, in the clamping process action stable, can arbitrarily not move; The 2nd, clamp great efforts, be difficult to take out gallbladder if cholelithiasis is excessive, calculus can be pressed from both sides broken back and from gallbladder, take out.

Clamp of the present utility model has gets stone bowl 11, be bowl-type in the clamp, two clamps clamp sealing around the back, the space of two clamps is ellipsoid 20, because the granule of calculus varies, especially cholelithiasis has mud type, and the application of clamp is both can to take out by horsestone, also calculus can be pressed from both sides broken back and take out, the mud type calculus can also be clipped in the spatial ellipsoid 20 and take out.

Direct-view described in the utility model Wicresoft is meant in the operation process to undergo surgery under direct-view without pneumoperitoneum certain space not to be arranged in the human body body.

Claims

1. the thing pincers are got by a direct-view Wicresoft, comprise fixedly clamp, active clamp, claw beam, push rod, flexible handle, jump ring, fixed handle, rinse piece, get stone bowl, rotator, fixed cover, steel ball, steel ball spacer, adapter sleeve, rotary body and draw-bar seat, it is characterized in that: what all have bowl-type on described fixedly clamp and active clamp gets the stone bowl, sealing around when two clamps close up, the centre of two clamps is ellipsoid.
