Abstract

The utility model relates to a skin tissue pathological specimen collecting tool, in particular to a novel skin inspection sampling trepan, which comprises a cylindrical trepan body, wherein the two ends of the trepan body are provided with openings, and the front end of the trepan body is an annular ring cutter. The novel skin inspection sampling trepan is characterized in that a circular rubber piston is arranged in the trepan body, the front end of a pull rod is hinged and connected with the rubber piston, the back end of the pull rod extends out of the back end of the trepan body, and a graduated scale is arranged on the trepan body. The novel skin inspection sampling trepan has the advantages that the structure is simple, the operation is simple and stable, the edges of sampled specimens are regular, the thickness is easy to control, the specimens are prevented from getting tissue damage through being extruded by tweezers, the quality of the specimens is improved, the structural design is reasonable, the operation time is shortened, and the pain of patients is reduced.

Description

A kind of novel skin check sampling trepan

Technical field

This utility model relates to a kind of skin histopathology collection of specimens instrument, particularly relates to a kind of novel skin check sampling trepan.

Background technology

There is important value in skin histopathology to dermopathic diagnosis, to the generation of understanding disease, develop, lapse to, body general body state and all significant to the selection of Therapeutic Method.Seek out the high pathology picture of value regular BIAO and BEN must be arranged.The method of collection of specimens at present mainly the perform the operation method of cutting, trepan method and cut method.Wherein, it all is directly the skin of morbidity to be cut down and directly obtains BIAO and BEN with scalpel with the method that cuts that operation cuts method, because of big, hemorrhage many, the operative scar of wound than in clinical practice, being restricted greatly, generally be not used.Generally adopt the trepan method at various big hospital at present, be adapted to less early stage skin lesion especially or be confined to show shallow place or operation cuts difficult person; Corneal trephine is that department of dermatologry is got one of the most frequently used instrument of Pathologic specimen, and this trepan front end has circular cutter, after trepan is got into patient's subcutaneous tissue, takes off trepan, clamps BIAO and BEN with tweezers, cuts BIAO and BEN with knife or scissors at fat deposit; Ring cutting causes the BIAO and BEN incisxal edge not sharp keen neat repeatedly, and the tangent plane shape is owed drawbacks such as regular, influence the pathological observation result, causes acatalepsia or difficult diagnosis, simultaneously the operating time longer, patient's stress is also just bigger; Because of trepan does not have depth sign, the thickness of the BIAO and BEN that is easy to get is not up to standard.

Summary of the invention

The technical problem that this utility model will solve is; To the deficiency of prior art and a kind of technical scheme of novel skin check sampling trepan is provided; This scheme can make the skin histology collection of specimens easily and fast, and the BIAO and BEN thickness qualification rate that collects is high, can reduce patient's misery.

This utility model is achieved in that a kind of novel skin check sampling trepan, and it comprises the cylindrical shape trepan body of both ends open; Trepan body front end is the Ring-shape cutter of annular; It is characterized in that, in the trepan body, be provided with the round rubber piston, pull bar front end and rubber piston are hinged; Back end of tie rod stretches out trepan body rear end, and said trepan body is provided with rule.

Said Ring-shape cutter lateral surface is perpendicular to the plane at blade place, and the angle between medial surface and the lateral surface is 1～2 degree.

Said trepan body rear end is provided with hand-held retaining head, and said pull bar is any one of triangular type or four rib types, and back end of tie rod is provided with handle.

The beneficial effect of this utility model is, this utility model is simple in structure, and simple to operate stable, BIAO and BEN neat in edge, the thickness of getting is easy to control, avoids BIAO and BEN to receive the tweezers extruding to cause tissue damaged, improved specimen quality; Reasonable in design has shortened operating time, has reduced patient's misery.

Description of drawings

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

Wherein, 1-handle, 2-pull bar, 3-hand-held retaining head, 4-trepan body, 5-rubber piston, 6-rule, 7-Ring-shape cutter.

The specific embodiment

Further specify below in conjunction with the concrete structure and the principle of accompanying drawing this utility model.

As shown in the figure, a kind of novel skin check sampling trepan of this utility model, it comprises the cylindrical shape trepan body 4 of both ends open; Trepan body 4 front ends are the Ring-shape cutter 7 of annular; It is characterized in that, in trepan body 4, be provided with round rubber piston 5, pull bar 2 front ends and rubber piston 5 are hinged; Trepan body 4 rear ends are stretched out in pull bar 2 rear ends, and said trepan body 4 is provided with rule 6; Said Ring-shape cutter 7 lateral surface are perpendicular to the plane at blade place, and the angle between medial surface and the lateral surface is 1～2 degree; Said trepan body 4 rear ends are provided with hand-held retaining 3, and said pull bar 2 is any one of triangular type or four rib types, and pull bar 2 rear ends are provided with handle 1.

When using this utility model; Pull bar 2 shifted onto between the blade that correct position makes rubber piston 5 and Ring-shape cutter 7 has a segment distance to be enough to fill the skin biopsy tissue; Hand-held trepan body 4; Make directly contact patient skin of Ring-shape cutter 7, Ring-shape cutter 7 also is drilled into subcutaneous tissue rapidly perpendicular to patient typical case skin lesion place, control the degree of depth of ring cutting through the rule 6 on the observation trepan body 4; Hands grasps trepan body 4 through hand-held retaining 3 behind the ring cutting, and the handle 1 on the other hands pull pull bar 2, pull bar 2 drive rubber pistons 5 and rise to make and form stronger negative pressure in the trepan body 4 with the BIAO and BEN sucking-off.

Stability when the pull bar 2 of this utility model is designed to triangular type or four rib types and has kept pull in use, apostle's hand operated is more stable; Ring-shape cutter 7 lateral surface of this utility model are perpendicular to the plane at blade place; Angle between medial surface and the lateral surface is 1～2 degree; Such design both can make blade sharper, can prevent that again skin sample cutting-out back from causing the defective of leaking gas and can not inhale because of contraction; BIAO and BEN is controlled the degree of depth of ring cutting through observing rule 6 on the trepan body 4 in gatherer process, BIAO and BEN neat in edge, the thickness got are qualified, make BIAO and BEN for pathological diagnosis provides high-quality.Operating process is simple and direct, easy, convenient, has shortened operating time, has reduced patient's misery.
