Description
Technical field
The invention belongs to medical instruments field, particularly relate to a kind of skin histopathology sample collection instrument---pressing type skin biopsy Ring-shape cutter.
Background technology
At present, along with the raising of economic development and living standards of the people, people more and more pay attention to the health requirements of self skin.There is important value in skin histopathology to dermopathic diagnosis, meanwhile, to understand disease generation, develop, lapse to, body general body state and all significant to the selection of Therapeutic Method.Want to obtain the pathological picture that value is higher, must have regular specimen.The method of dermatological specimens collection has three kinds: operation harvesting, trepan method and cut method.Wherein, operation harvesting and to cut method be directly the skin of morbidity to be cut down and directly obtains sample with scalpel, because of wound large, hemorrhage many, operative scar is larger, in clinical practice, be restricted.Trepan method generally adopts at various big hospital at present, is specially adapted to less early stage skin lesion or is 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 pathology sample, and this trepan front end has circular cutter, trepan is got into after patient's subcutaneous tissue, takes off trepan, clamps sample with tweezers, cuts sample with knife or shears at fat deposit.The weak point of this trepan is: on Ring-shape cutter, there is no scale, the degree of depth that makes to draw materials is wayward, as inadequate in the degree of depth, can cause and draw materials unsuccessfully; The manual spiral mode that enters skin is taked in drilling through of operation trepan, and greatly random, accuracy is inadequate.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, a kind of simple in structure, easy to operate pressing type skin biopsy Ring-shape cutter is provided.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of pressing type skin biopsy Ring-shape cutter, comprises and presses handle, central slide bar, back-moving spring, outer sleeve, middle sleeve, cutter head sheath and girdling cutter head.It is characterized in that: described outer sleeve and cutter head sheath are screwed on respectively on middle sleeve, press handle and girdling cutter head and be screwed on respectively on central slide bar, central slide bar is arranged on the inside of middle sleeve by back-moving spring.The center of described outer sleeve is circular hollow inner chamber shape, has long screw stricture of vagina on one end of its inwall.One end, center of described middle sleeve is circular hollow inner chamber shape, and the other end is to have corner angle to have the hollow lumen shape of plane, and all there is tap at outer wall two ends, and wherein long screw stricture of vagina one end is provided with deep calibration chi.The center of described cutter head sheath is circular hollow inner chamber shape, on one end of inwall, has tap.One end of described central slide bar is cylindrical, is provided with external screw thread, and the other end is to have corner angle to have the cylindrical body of plane, and cylindrical body top is provided with a circular counter bore, and counterbore inwall has tap, and central slide bar is provided with Anti-extrusion projection.The described handle of pressing is to establish female cap-like structure.Described girdling cutter head is cylindrical shape stalloy, and one end is fixed with and is provided with externally threaded cylindrical knife shank, is provided with an air-vent near handle of a knife place, and other end lateral surface is perpendicular to the plane at blade place, and the angle between medial surface and lateral surface is 2～3 degree.
Advantage of the present invention and beneficial effect are:
This pressing type skin biopsy Ring-shape cutter adopts cylindrical shape stalloy girdling cutter head, and middle sleeve outer wall is provided with deep calibration chi, and the specimen neat in edge of getting, is standard cylindrical, and the degree of depth is controlled, has greatly improved sampling success rate.Reasonable in design of the present invention, has increased the stability operating, and has shortened operating time simultaneously, reduces patient's misery, and operating process is simple and convenient, is suitable for clinical application.
