Abstract

The utility model discloses a biopsy forceps, which comprises forceps holders, connecting plates, a binding clip base, a forceps lever, an insulation sleeve, a forceps base, a pull rod base, a fixed handle, a movable handle, a pull rod connecting shaft, a pull rod, a rotating wheel and a rotating wheel sleeve. The two forceps holders intercrossing each other are fixed to the binding clip base via a forceps holder connecting pin and are also fixed to the two connecting plates via the connecting pin. The two connecting plates are fixed to the pull rod via a pull rod connecting pin. The biopsy forceps is characterized by also comprising a compression spring, a rolling ball, a fixed hub and a rotating shaft. The fixed hub is equipped with limit seats and the rotating shaft is sleeved inside the fixed hub. One end of the rotating shaft is connected with a nut and the fixed hub clamped with the fixed handle is fixedly connected with the fixed handle. The compression spring and the rolling ball are arranged inside the rotating wheel sleeve. The rotating wheel sleeve sleeved inside the other end of the rotating shaft is fixedly connected with the rotating shaft. The rolling ball is pressed on the limit seats by the compression spring. Each of the two forceps holders is equipped with an elliptical clamping bowl. The biopsy forceps equipped with eight limit seats is reasonable in structural design. Since the forceps holders are equipped with the elliptical clamping bowls, the bite-cutting, the sampling, the testing and the analyzing of focus positions can be effectively performed. The biopsy forceps is better in application effect, convenient and safe.

Description

Biopsy forceps

Technical field

This utility model relates to a kind of direct-view the straight and is exclusively used in human abdominal cavity inner disease foci position in the operation in the little otch human abdominal cavity and stings the biopsy forceps that cuts the sample assay.

Background technology

In direct-view peritoneoscope human abdominal cavity, in the operation, need sting human abdominal cavity inner disease foci position and cut the sample assay, help the diagnosis of the state of an illness and normally carrying out of operation.Prior art is in operation, cuts with common nipper and scalpel and grasps sample examination and analysis, and its defective is that the sampling operation is loaded down with trivial details, and nipper grasps and easily comes off, and easily causes secondary to grasp operation, does not satisfy ideal surgical effect.

The utility model content

The purpose of this utility model is the weak point that overcomes original technology, and provides a kind of direct-view the straight to be exclusively used in human abdominal cavity inner disease foci position in the operation in the little otch human abdominal cavity and to sting the biopsy forceps that cuts the sample assay.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this biopsy forceps, comprise clamp, connecting plate, the binding clip seat, claw beam, insulation sleeve, the pincers seat, draw-bar seat, fixed handle, flexible handle, the pull bar connecting axle, pull bar, runner, rotaring wheeling sleeve, flexible handle has pull rod slot, fixed handle is connected with connecting bolt with flexible handle, the pull bar connecting axle is fixedlyed connected with draw-bar seat, the pull bar connecting axle is inserted in fixed handle, draw-bar seat cooperates with pull rod slot, two clamps cross one another and are fixed on the binding clip seat with the clamp connecting pin, two clamps are fixed on two connecting plates with the connecting plate pin, two connecting plates are fixed on the pull bar with link pin, the binding clip seat is fixedlyed connected with claw beam, insulation sleeve is inserted in claw beam to be fixed, it is fixedly connected that the pincers cover for seat is gone into runner, the pincers seat, runner is inserted in insulation sleeve, the pincers seat is fixedlyed connected with insulation sleeve, pull bar is inserted in claw beam, pull bar is inserted in pull bar connecting axle and fixedly connected, it is fixedly connected that runner is inserted in rotaring wheeling sleeve, it is characterized in that also being provided with stage clip, ball, fixed cover, rotating shaft, fixed cover has limit base, fixed cover is inserted in rotating shaft, rotating shaft one end is connected with nut, it is fixedly connected that fixed cover snaps in fixed handle, stage clip, ball is installed in the rotaring wheeling sleeve, and it is fixedly connected that rotaring wheeling sleeve is inserted in the other end of rotating shaft, ball is pressed on the limit base by stage clip, all has ellipse folder bowl on two clamps.

Limit base described in the utility model is eight.

This utility model reasonable in design, the art designs of clamp are used ellipse folder bowl, carry out the kitchen range position effectively and sting and cut the sample chemical examination and analyze, and result of use is good, convenient and safe.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

The specific embodiment

Referring to Fig. 1, this utility model biopsy forceps comprises clamp 1, connecting plate 2, ellipse folder bowl 3, link pin 4, clamp connecting pin 5, binding clip seat 6, claw beam 7, insulation sleeve 8, pincers seat 9, runner 10, rotaring wheeling sleeve 11, stage clip 12, ball 13, fixed cover 14, limit base 15, rotating shaft 16, nut 17, draw-bar seat 18, pull rod slot 19, connecting bolt 20, fixed handle 21, flexible handle 22, pull bar connecting axle 23, pull bar 24, connecting plate pin 25, flexible handle 22 has pull rod slot 19, and fixed handle 21 and flexible handle 22 usefulness connecting bolts 20 are connected and fixed and can rotate; Pull bar connecting axle 23 is fixing with draw-bar seat 18 welding, and pull bar connecting axle 23 is inserted in fixed handle 21, and draw-bar seat 18 snaps in 19 identical connections of pull rod slot just; Fixed cover 14 has (eight) limit base 15, and rotating shaft 16 is inserted in fixed cover 14 and can be rotated, and rotating shaft 16 1 ends are tightened with nut 17; It is fixing that fixed cover 14 snaps in fixed handle 21; Stage clip 12 and ball 13 are installed in the rotaring wheeling sleeve 11, and the other end that rotaring wheeling sleeve 11 is inserted in rotating shaft 16 is tightened fixing, and ball 13 is stuck in limit base 15 just and coincide under the effect of stage clip 12, and rotaring wheeling sleeve 11 has eight orientations in rotation.

All have ellipse folder bowl 3 on two clamps 1, coincide into ellipsoid during clamping mutually, two clamps 1 cross one another, be fixed on the binding clip seat 6 and can rotate with clamp connecting pin 5 at infall, two clamp 1 usefulness connecting plate pins 25 are fixed on two connecting plates 6 and can rotate, two connecting plate 2 usefulness link pins 4 are fixed on the pull bar 24, and binding clip seat 6 is fixedlyed connected with claw beam 7; It is fixing that insulation sleeve 8 is inserted in claw beam 7, pincers seat 9 is inserted in 10 runners to be tightened fixingly, and it is fixing with insulation sleeve 8 gummeds that pincers seat 9 and 10 runners are inserted in insulation sleeve 8 forceps major seats 9, and pull bar 24 is inserted in claw beam 7, it is fixing that pull bar 24 is inserted in pull bar connecting axle 23 gummeds, and runner 10 is inserted in rotaring wheeling sleeve 11 to be tightened fixing.
