Description
Technical field
The invention belongs to medical instruments field, particularly relate to a kind of skin histopathology sample collection instrument---elastic press 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 elastic press 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 elastic press type skin biopsy Ring-shape cutter, comprises outer sleeve, middle sleeve, depth adjustment sleeve, center slide bar, reset cutting ferrule, bayonet lock, compression spring, back-moving spring, girdling cutter head, outer cuff, release-push and deep calibration chi.It is characterized in that: described depth adjustment sleeve is screwed on middle sleeve, center slide bar is installed in middle sleeve, reset cutting ferrule is contained in slide bar upper end, center by compression spring and back-moving spring cunning, outer sleeve is screwed on reset of card and puts, girdling cutter head is screwed on slide bar lower end, center, outer cuff is packed on middle sleeve, and release-push is placed between outer cuff and middle sleeve.Described outer sleeve is circular hollow cap-like structure, and its inwall is provided with one end tap.Described middle sleeve is circular hollow inner chamber shape, and one end is to have corner angle to have the hollow lumen shape of plane, and the outer wall of the other end is provided with a long screw stricture of vagina, makes one section of deep calibration chi on long screw stricture of vagina, middle part system one square opening.The center of described depth adjustment sleeve is circular hollow inner chamber shape, has long screw stricture of vagina on one end of inwall.One end of described center slide bar is to have corner angle to have the cylindrical body of plane, cylindrical body end is provided with Anti-extrusion projection and a groove, one end of back-moving spring is installed in groove, the other end of center slide bar is cylindrical, head is provided with a circular counter bore, counterbore inwall has tap, is shaped with an elastic bayonet lock on the slide bar of center.One end of described reset cutting ferrule is circular hollow inner chamber shape, and the other end is to have corner angle to have the hollow lumen shape of plane.Described girdling cutter head is cylindrical shape stalloy, and one end is fixed with and is shaped 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.Described outer cuff is circular hollow inner chamber shape, system one square opening on it.Described release-push is square prism, and edge, middle part is shaped with Anti-extrusion projection.
Advantage of the present invention and beneficial effect are:
This elastic press type skin biopsy Ring-shape cutter adopts and suppresses mode, and moment completes feed, has greatly shortened operating time, has reduced patient's misery.Meanwhile, adopt cylindrical shape stalloy girdling cutter head, middle sleeve outer wall arranges deep calibration chi, makes the specimen neat in edge got, be standard cylindrical, and the degree of depth is controlled.Reasonable in design of the present invention, has increased the stability operating, and operating process is simple and convenient, is suitable for clinical application.
