Abstract

The utility model relates to the technical field of medical apparatus, and discloses a forceps-type tissue samples shearing device which can cut and take cancer tissues, adjacent tissues and normal tissues once, and comprises a forceps clip (1) and a shear head (2), wherein the forceps clip (1) comprises a pair of shear forceps limbs (1.1) and a connecting shaft (1.2), and the two shear forceps limbs are connected by the connecting shaft in a cross shape. The shear head (2) is fixed on the top ends of front arms of the shear forceps limbs, and comprises a shear tool holder (2.1) and a shear tool gasket (2.2), wherein a shear tool (2.3) is vertically fixed on the inner surface of the shear tool holder (2.1) in a square frame shape or a hollow cylindrical shape, each tool holder is connected and provided with three uniformity shear tools in parallel, and the tool holder is provided with a square or a round hole (2.4) which is matched with an inner cavity of the shear tool. The inner surface of the shear tool gasket (2.2) is flat, and the shear tool holder (2.1) and the shear tool gasket (2.2) are meshed when the shear head (2) is closed. The forceps-type tissue samples shearing device has simple structure, convenient operation and safe use, tissue mass which are cut and taken are structured, and tissue cells can not be mutually polluted, thereby leading experimental results to be more reliable.

Description

A kind of jaw type tissue specimen cutting device

Technical field

This utility model relates to tissue specimen and cuts technical field, is a kind of jaw type tissue specimen cutting device that can disposablely cut cancerous tissue, cancer beside organism and normal structure.

Background technology

Clinically, the tissue that excision is got off need cut tissue specimen usually and be used for pathology and differentiate or be used for pathogenic mechanism research, especially need cut cancerous tissue, cancer beside organism and contiguous normal structure simultaneously as specimen to the tumor tissues of excision.What be used at present that specimen cuts is scalpel, promptly draw by cutter from left to right along cancerous tissue, cancer beside organism and adjacent normal structure direction earlier and draw with scalpel, serve as the cutting of sign row vertical direction with cancer peplos again, obtain cancerous tissue piece, cancer beside organism's piece and normal structure piece respectively, need respectively cut 6-10 block organization usually.Not only complex operation is wasted time and energy, and the specimen that cuts out-of-shape often, not of uniform size, especially as quality such as liver organization softer organize more difficult operation, organizing sometimes of cutting can not be used, because nonstandard tissue specimen can cause inaccuracy to experiment; Draw in the process of drawing by cutter at scalpel simultaneously, cause the mutual pollution of cell between the different tissues easily, also can influence experimental data; Moreover operator are easy to sustain damage when using the scalpel cutting, might cause nosocomial infection.

Summary of the invention

The purpose of this utility model provides and a kind ofly easy and simple to handlely saves time, the regular standardized jaw type tissue specimen cutting device of specimen.

This utility model is made up of clamp and cutting head, and clamp is made up of a pair of cutting nipper limbs and a connecting axle, and connecting axle is with two cross-shaped connections of cutting nipper limbs; Cutting head is individually fixed in the top of two cutting nipper limbs forearms, by shearing knife rest and forming with the shears pad of this shearing knife rest coupling, shears with square frame or open circles tubular vertical fixing in the inner face of shearing knife rest, laterally be provided with three sheaves of the same form on the knife rest side by side, knife rest is provided with the square or circular port that is complementary with the shears inner chamber, so that the piece of tissue of shearing is taken out from the shears inner chamber.Said shears pad inner face is smooth, with it tissue to be cut is held up, and when cutting head closes up, shears knife rest and the interlock of shears pad, and shears just will be organized cutting-out, cutting head be opened again, and take out piece of tissue respectively.

During use, to wait that cutting tissue shakeouts into certain thickness, with clamp cutting head is opened routinely, with cancer peplos serves as that sign inserts under the tissue to be cut with the shears pad, make cancer peplos be in first and second two shears intersections, two cutting nipper limbs of clamp are folded, the shears of cutting head and the mutual interlock of shears pad, downcut cancerous tissue, cancer beside organism and three piece of tissue of normal structure simultaneously, after taking out the tissue specimen piece, reach successively, repetitive operation is 6-10 time as stated above, is easy to obtain required tissue specimen.

This utility model is simple in structure, and is easy to operate, safe in utilization, and the piece of tissue that cuts is regular standardized, and histiocyte can not pollute mutually, makes experimental result more reliable.

The specific embodiment

Now in conjunction with the accompanying drawings and embodiments this utility model is described in detail.

This utility model is made up of clamp 1 and cutting head 2, and clamp 1 is made up of a pair of cutting nipper limbs 1.1 and a connecting axle 1.2, and connecting axle is with two cross-shaped connections of cutting nipper limbs; Cutting head 2 is fixed in the forearm top of cutting nipper limbs, by shearing knife rest 2.1 and forming with the shears pad 2.2 of its coupling, shears 2.3 with square frame shape or open circles tubular vertical fixing in the inner face of shearing knife rest 2.1, laterally be provided with three sheaves of the same form on the knife rest side by side, knife rest is provided with the square or circular port 2.4 that is complementary with the shears inner chamber, so that the piece of tissue of shearing is taken out from the shears inner chamber; Shears pad 2.2 inner faces are smooth, with it tissue to be cut held up, and when cutting head closes up, shear knife rest 2.1 and 2.2 interlocks of shears pad, and shears 2.3 just will be organized cutting-out, cutting head be opened again, and respectively piece of tissue be taken out.

Embodiment 1.

A pair of cutting nipper limbs 1.1 forearms of the present utility model are convexly curved, ovalize when closing up, cutting head 2 is fixed in the forearm top of shearing clamp, shear knife rest 2.1 and be prolate side's bodily form, long 3 centimetres, wide 1 centimetre, thick 0.8 centimetre, be provided with three square holes of the same form side by side, 0.3 centimetre of every hole length of side, perpendicular three square frame shape shears 2.3 inner chambers that are fixed in this communicate, and each frame type shears length of side is 0.8 centimetre, high 0.8 centimetre, shears pad 2.2 and the flat cuboid coupling of shearing knife rest 2.1.

Basis is practical can make different specifications and models on demand.
