Abstract

The utility model relates to a V-shaped nipper, comprising nipper clamps, a pull-rod connecting pin, a nipper clamp connecting pin, a nipper clamp seat, a nipper rod, an insulating sleeve, a nipper seat, a rotary wheel, a rotary wheel sleeve, a pressing spring, a rolling ball, a fixed sleeve, a limiting seat, a rotary shaft, a nut, a pull-rod seat, a pull-rod groove, a connecting bolt, a fixed handle, a movable handle, a pull-rod connecting shaft, a pull rod, connecting plate pins and connecting plates. The V-shaped nipper is characterized in that the number of the nipper clamps is two; the nipper clamps are opened and closed in a V shape; one end of each nipper clamp is provided with nondestructive teeth, and all the nondestructive teeth of the nipper clamps are mutually coincided; the nipper clamps are provided with release grooves; the other ends of the two nipper clamps are mutually crossed; the crossed position is rotatably arranged on the nipper clamp seat by the nipper clamp connecting pin; the nipper clamp seat is connected with the nipper rod; the bottom ends of the two nipper clamps are respectively and rotatably arranged on the two connecting plates by the connecting plate pins; and the connecting plates are fixed on the pull rod by the pull-rod connecting pin. In the V-shaped nipper, the pipe-shaped organs can be effectively dragged and separated, and the use in the operation is convenient and safe.

Description

The V-type nipper

Technical field

This utility model relates to and a kind ofly in the operation, draws and free V-type nipper the genus technical field of medical instruments specially for the pipe of people's internal lesions position periphery in direct-view peritoneoscope human body.

Background technology

In direct-view peritoneoscope human body in the operation, need draw and dissociate the pipe of human abdominal cavity inner disease foci position periphery, so that operative site has the operation that undergos surgery of enough spaces.Prior art is to adopt common nipper that the pipe of lesions position periphery is drawn and dissociate, because of common nipper does not have special-purpose clamp design, also not harmless flute profile and release groove design very easily cause the damage of organ pipe, do not satisfy ideal surgical effect.

The utility model content

Technical problem to be solved in the utility model is to overcome deficiency of the prior art and provide a kind of effectively pipe to be drawn and to dissociate the safe V-type nipper easy to use of performing the operation.

The technical scheme in the invention for solving the above technical problem is: this V-type nipper, comprise clamp, link pin, the clamp connecting pin, the clamp seat, claw beam, insulation sleeve, the pincers seat, runner, rotaring wheeling sleeve, stage clip, ball, fixed cover, limit base, rotating shaft, nut, draw-bar seat, pull rod slot, connecting bolt, fixed handle, flexible handle, the pull bar connecting axle, pull bar, connecting plate pin and connecting plate, it is characterized in that: described clamp has two, the V-shaped folding of clamp, two clamp one ends have the harmless tooth that coincide mutually, have release groove on the clamp, two clamp other ends cross one another, infall rotates by the clamp connecting pin and is arranged on the clamp seat, the clamp seat is connected with claw beam, the bottom of two clamps is rotated respectively by the connecting plate connecting pin and is arranged on two connecting plates, and connecting plate is fixed on the pull bar by link pin.

The space is left in the clamp stage casing during two clamp interlocks described in the utility model.

Release groove described in the utility model is an oblong.

This utility model compared with prior art has the following advantages: clamp of the present utility model is V-shaped and movable flexible, and design has harmless tooth and release groove on the clamp, and during the clamp interlock, the space is left in the clamp stage casing, provides certain space for clamping organ.The flute profile of harmless tooth is rounded, can not damage organ pipe during clamping.The art designs of release groove makes the organ pipe clamping plane littler, simultaneously also more difficult injury organ.

Fig. 3 is an A portion enlarged drawing among Fig. 1.

The specific embodiment

Referring to Fig. 1-Fig. 3, this utility model comprises clamp 1, release groove 2, harmless tooth 3, link pin 4, clamp connecting pin 5, clamp 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, connecting plate 26.

Have pull rod slot 19 on the flexible handle 22, fixed handle 21 and flexible handle 22 usefulness connecting bolts 20 are rotationally connected.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.Have a plurality of limit bases 15 on the fixed cover 14, fixed cover 14 is inserted in rotating shaft 16, and can rotate in fixed cover 14, and rotating shaft 16 1 ends are tightened with nut 17, and 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 snaps in limit base 15 just under the effect of stage clip 12, and rotaring wheeling sleeve 11 has a plurality of orientations in rotation.

Have release groove 2 on two clamps 1, one end of clamp 1 has harmless tooth 3, harmless tooth 3 coincide mutually when clamping, clamp 1 other end crosses one another, be arranged on the clamp seat 6 with 5 rotations of clipper joint pin at infall, clamp seat 6 is connected with claw beam 7, and space 1-1 is left in the stage casing of clamp during two clamp 1 interlocks.The bottom of two clamps 1 is rotated with connecting plate pin 25 and is arranged on two connecting plates 26, and two connecting plate 26 usefulness link pins 4 are fixed on the pull bar 24.It is fixing that insulation sleeve 8 is inserted in claw beam 7, pincers seat 9 is inserted in runner 10 to be tightened fixing, after pincers seat 9 and runner 10 integral body are inserted in insulation sleeve 8, pincers seat 9 is fixing with insulation sleeve 8 gummeds, pull bar 24 is inserted in claw beam 7, and pull bar 24 1 ends are connected with connecting plate 26, and pull bar 24 other ends are inserted in pull bar connecting axle 23 and gummed is fixing, runner 10 is inserted in rotaring wheeling sleeve 11 to be tightened fixingly, and runner 10 is connected with fixed handle 21.

When this utility model uses, the flexible handle 22 of holding with a firm grip, flexible handle 22 pushing drawing rods 24, pull bar 24 promotes clamp 1, clamp 1 closure.Decontrol flexible handle 22, clamp 1 opens.Clamp 1 of the present utility model can rotate by 360 degree, and what be convenient to perform the operation carries out smoothly, reaches its multifunctionality.And whole metal and the exotic material of adopting made, and can use the disinfectant solution irrigation and disinfection, also can use high-temperature sterilization.
