Description

A kind of tissues of experimental animals tweezer

Technical field

This utility model relates to a kind of tweezers, particularly a kind of laboratory animal tissue clamps.

Background technology

In laboratory animal experiment, the tissue clamps that grasping tissue is used is common tool.The rear end of tissue clamps two side arms links together, and the front end of two side arms is corresponding gib head and hook groove, by gib head and hook groove, completes clamping task.

The meshing jaws of existing tissue clamps is the meshing jaws of single head, and a tooth is to a groove, if want, two skins is picked up simultaneously, easily occurs slip phenomenon, clamp firmly not, and wound is identical not accurate enough simultaneously, and repetitive operation is many, and efficiency is low.

Utility model content

This utility model has overcome the shortcoming of prior art, provide the meshing jaws of a kind of double end, two teeth to two grooves, and can be convenient for changing the laboratory animal tissue clamps of tweezer head, for capturing continuously wound both sides tissue, so that wound is sewn, device is accurately caught and closure.This closing course can be operated separately by those skilled in the art, thereby can effectively shorten operating time.Different animals sometimes needs different tweezer heads, often occurs changing the situation of tweezer head in experiment.

A kind of tissues of experimental animals tweezer of the present utility model, comprise: side arm one, side arm two, intermediate arm, tweezer are first, tweezer head two, double head hook groove, bottom, described intermediate arm is in the middle of side arm one and side arm two, and one end of side arm one, side arm two and intermediate arm links together, and forms bottom; The free end of side arm one is that tweezer is first, and the free end of side arm two is that the free end of tweezer head two, intermediate arm is double head hook groove, and tweezer is first corresponding closed with double head hook groove respectively with tweezer head two;

Tweezer is first, tweezer head two, double head hook groove are detachably connected by shell fragment and draw-in groove with corresponding side arm one, side arm two, intermediate arm respectively.

Wherein, at side arm one and side arm two outer surface middle parts, be provided with anti-slip tank, anti-slip tank is many parallel groove structures.

Side arm one of the present utility model, side arm two and intermediate arm can converge at some when closed.Side arm one and side arm two are positioned at the both sides of intermediate arm, and wherein, when side arm one is closed with intermediate arm, the locating piece on side of the locating slot on side arm one and intermediate arm is fastened togather; When side arm two is closed with intermediate arm, the locating piece on another side of the locating slot on side arm two and intermediate arm is fastened togather; Operator can selectively capture the tissue of wound both sides, make the better more effective closure of wound of stiching instrument energy, thereby can guarantee that wound coincide accurately.And the design that tweezer is first, tweezer head two, double head hook groove are detachably connected by shell fragment and draw-in groove with corresponding side arm one, side arm two, intermediate arm respectively, can need to change easily tweezer head according to experiment.

This utility model, in skin closure process, can disposablely be clamped two skins simultaneously, makes clamping firmly, and wound coincide accurately, shortens operating time, improves operation efficiency.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the side arm one tweezer head disassembling part structural representation first with tweezer;

In figure 1, side arm one; 2, side arm two; 3, intermediate arm; 4, bottom; 5, tweezer is first; 6, tweezer head two; 7, double head hook groove; 8, anti-slip tank; 9, tweezer head disassembling part; 10 draw-in grooves, 11 shell fragments.

The specific embodiment

Embodiment:

As depicted in figs. 1 and 2, a kind of tissues of experimental animals tweezer of the present utility model, comprise: side arm one, side arm two, intermediate arm, tweezer are first, tweezer head two, double head hook groove, bottom, described intermediate arm is in the middle of side arm one and side arm two, one end of side arm one, side arm two and intermediate arm links together, and forms bottom; The free end of side arm one is that tweezer is first, and the free end of side arm two is that the free end of tweezer head two, intermediate arm is double head hook groove, and tweezer is first corresponding closed with double head hook groove respectively with tweezer head two;

Tweezer is first, tweezer head two, double head hook groove are detachably connected by shell fragment and draw-in groove with corresponding side arm one, side arm two, intermediate arm respectively.

Wherein, at side arm one and side arm two outer surface middle parts, be provided with anti-slip tank, anti-slip tank is many parallel groove structures.

Side arm one of the present utility model, side arm two and intermediate arm can converge at some when closed.Side arm one and side arm two are positioned at the both sides of intermediate arm, and wherein, when side arm one is closed with intermediate arm, the locating piece on side of the locating slot on side arm one and intermediate arm is fastened togather; When side arm two is closed with intermediate arm, the locating piece on another side of the locating slot on side arm two and intermediate arm is fastened togather; Operator can selectively capture the tissue of wound both sides, make the better more effective closure of wound of stiching instrument energy, thereby can guarantee that wound coincide accurately.And the design that tweezer is first, tweezer head two, double head hook groove are detachably connected by shell fragment and draw-in groove with corresponding side arm one, side arm two, intermediate arm respectively, can need to change easily tweezer head according to experiment.

The tweezer head disassembling part structure that side arm one is first with tweezer is identical with the tweezer head disassembling part structure of tweezer head disassembling part structure, intermediate arm and the double head hook groove of tweezer head two with side arm two.2, accompanying drawing is listed the side arm one tweezer head disassembling part structure chart first with tweezer.
