Description

The not damaged nipper

Technical field

This utility model relates to a kind of medical calm, and particularly a kind of not damaged nipper is exclusively used in the direct-view peritoneoscope abdominal operation, and the organ pipe tissue of human body larger volume grasps, and belongs to medical instruments field.

Background technology

In the operation of direct-view peritoneoscope human abdominal cavity, need the organ pipe of organizing of intraperitoneal larger volume be grasped, so that operation is carried out smoothly.Prior art is to adopt common nipper that the organ pipe of organizing of larger volume is grasped; Its defective is that the design of common nipper clamp tooth is interconnected general flute profile; Unshielded radian release groove, grip main point damaged tissue organ pipe during extracting, grip Xiao Yi comes off; Also might cause the secondary wound, be difficult to obtain ideal surgical effect.

Summary of the invention

This utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and a kind of not damaged nipper is provided, and what make larger volume in the direct-view peritoneoscope abdominal operation organizes the organ pipe grip good.

This utility model solves the problems of the technologies described above the technical scheme of being taked: this not damaged nipper; Comprise fixed handle, flexible handle, back-moving spring, tooth bar, latch, shell fragment, binding clip pulling seat, draw-bar seat, pull bar, rest pad, claw beam, bearing block, bearing holder (housing, cover), fixture block, bearing, irrigator, two clamps, clamp holder and two connecting plates; Its construction features is: described two clamps are installed on the clamp holder through the clamp pin is active; The tail end of two clamps is separately fixed on two connecting plates with two connecting plate steady pins, and the other end of two connecting plates is installed on the pull bar with stay rod pin is active; Be fixed with rotator on the described bearing block, claw beam penetrates rotator and is fixed on the bearing block.

This utility model not damaged nipper, described two clamps are provided with not damaged type tooth and protection radian release groove, and when two clamps clamped, not damaged type tooth coincide mutually with protection radian release groove.

This utility model is compared with prior art; Have the following advantages and effect: reasonable in design, not damaged type tooth that is provided with on the clamp and protection radian release groove are used the not damaged nipper in direct-view peritoneoscope abdominal operation; The organ pipe of organizing that can carry out larger volume effectively grasps; Not damaged, grip is good, the safety easy to use of performing the operation.

Fig. 1 is the overall structure sketch map of this utility model embodiment not damaged nipper, the band broken section;

Fig. 2 overlooks enlarged diagram for binding clip position among Fig. 1, the band broken section.

Among the figure: 1 fixed handle, 2 flexible handles, 3 back-moving springs, 4 steady pins, 5 tooth bars, 6 latches, 7 shell fragments; 8 connecting pins, 9 binding clip pulling seats, 10 draw-bar seats, 11 pull bars, 12 rest pads, 13 claw beams, 14 rotator; 15 bearing blocks, 16 bearing holder (housing, cover)s, 17 fixture blocks, 18 bearings, 19 irrigators, 20 clamps, 21 not damaged type teeth; 22 clamp pins, 23 clamp holders, 24 connecting plates, 25 connecting plate steady pins, 26 stay rod pins, 27 protection radian release grooves.

The specific embodiment

Embodiment to this utility model is described further below in conjunction with accompanying drawing, and present embodiment provides detailed embodiment and concrete operating process, but the protection domain of this utility model is not limited to following embodiment.

Referring to Fig. 1, Fig. 2, the fixed handle 1 of present embodiment and flexible handle 4 active connections of 2 usefulness steady pins can rotate, and two rubber-like back-moving springs 3 compress mutually, are separately fixed on fixed handle 1 and the flexible handle 2; Tooth bar 5 usefulness connecting pins 8 are fixed on the flexible handle 2, and shell fragment 7 is connected as a single entity with the back-moving spring 3 that is fixed on the flexible handle 2, and withstands on the tooth bar 5, makes tooth bar 5 have elasticity; Latch 6 is connected as a single entity with fixed handle 1, and tooth bar 5 coincide with latch 6 couplings; Have binding clip pulling seat 9 on the flexible handle 2.

Rest pad 12 and the fixed handle 1 of embodiment are connected as a single entity; Rotator 14 is fixed on the bearing block 15; Claw beam 13 penetrates rotator 14 and is fixed on the bearing block 15, and two bearings 18 are inserted in bearing block 15, and bearing holder (housing, cover) 16 is inserted in bearing 18 and bearing block 15 chuckings; It is fixing that one end of fixture block 17 snaps in bearing holder (housing, cover) 16, and the other end is fixed on the rest pad 12; The irrigator 19 of band flushing hole is fixed on the rotator 14.

Two clamps 20 of embodiment are provided with not damaged type tooth 21 and protection radian release groove 27, and when two clamps 20 clamped, not damaged type tooth 21 coincide mutually with protection radian release groove 27; Two clamp 20 usefulness clamp pins 22 active being installed on the clamp holder 23; Can rotate; The tail end of two clamps 20 is separately fixed on two connecting plates 24 with two connecting plate steady pins 25, and the other end of two connecting plates 24 can rotate with stay rod pin 26 active being installed on the pull bar 11.
