Abstract
The invention provides a skin tissue pathological sample collecting tool, relates to a hand pressure rotation type skin trepan, and belongs to the technical field of medical apparatus and instruments. The hand pressure rotation type skin trepan comprises a pressing handle, a outer sleeve nut, a reset spring, a central rotating lever, an outer sleeve, an annular cutting tool bit, a depth regulating sleeve and a cross shaft. The hand pressure rotation type skin trepan is characterized in that the depth regulating sleeve is screwed at the lower end of the outer sleeve; the pressing handle is movably arranged at the upper end of the central rotating lever through the outer sleeve nut; the annular cutting toll bit is screwed at the lower end of the central rotating lever; the upper end of the central rotating lever is provided with the reset spring and the outer sleeve nut in a sleeving manner which are arranged inside the outer sleeve in a penetrating manner; the cross shaft of a spiral groove penetrating through the central rotating lever is arranged at the upper end of the outer sleeve; the outer sleeve nut is screwed at the upper end of the outer sleeve so as to prevent the cross shaft from being taken off. The hand pressure rotation type skin trepan adopts hand pressure rotation feeding and a cylindrical stalloy annular cutting tool bit, and the outer sleeve is provided with a depth dividing ruler, so that samples are easier to sample during sampling, the edges of sampled samples are in good order, the depth is controllable, and the sampling success rate is improved.
Description
Technical field
The invention belongs to medical instruments field, particularly relate to a kind of skin histopathology sample collection instrument---the rotary skin trepan of hand.
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, provide a kind of simple in structure, easy to operate hand rotary skin trepan.
The present invention solves its technical problem and is achieved through the following technical solutions:
The rotary skin trepan of a kind of hand, comprises and presses handle, cap nut, back-moving spring, central rotation bar, outer sleeve, girdling cutter head, depth adjustment sleeve and transverse axis.It is characterized in that: described depth adjustment sleeve is screwed on outer sleeve lower end, press handle and pass through cap nut removable mounting in central rotation bar upper end, girdling cutter head is screwed on central rotation bar lower end, central rotation bar upper end is set with back-moving spring and cap nut is installed in outer sleeve, outer sleeve upper end is provided with through the spiral fluted transverse axis on central rotation bar, cap nut is screwed on outer sleeve upper end, to prevent that transverse axis from deviating from.
And, described in to press handle upper end be bulb-type, lower end is cylindrical, cylindrical portion is arranged with external screw thread, cylindrical tip is provided with a conical counterbore.
And described central rotation bar is cylinder, top symmetric position has the helicla flute isometric with depth adjustment sleeve, top system one cone, and lower tip is provided with a circular counter bore, and counterbore inwall has tap.
And described girdling cutter head is cylindrical shape stalloy, one end is fixed with and is provided with externally threaded cylindrical knife shank, be provided with an air-vent near handle of a knife place, 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, and blade is waveform.
Advantage of the present invention and beneficial effect are:
The rotary skin trepan of this hand adopts hand rotation feed, and cylindrical shape stalloy girdling cutter head, arranges deep calibration chi on outer sleeve, lighter when sampling, to get specimen neat in edge, is standard cylindrical, and the degree of depth is controlled, greatly improve sampling success rate.Reasonable in design of the present invention, has increased the stability operating, and has shortened operating time, reduces patient's misery, and operating process is simple and convenient, is suitable for clinical application.
