Description
Technical field
The present invention relates to a kind of medicine equipment, specifically refer to a kind of ceramic scalpel.
Background technology
Currently used scalpel includes stainless steel blade and handle two parts, stainless steel blade can be gradually reduced with its sharpness of abrasion during using, after edges dull, stripping, excision to tissue impact, and are easy to rust corrosion after stainless steel blade abrasion simultaneously in disinfecting process.Along with the exploitation of new material, a kind of scalpel appearance produced with ceramic material, the scalpel that this material makes is corrosion-resistant, wear-resistant, be difficult to pollution, and it has enough sharpness simultaneously, it is possible to fully meet the needs performed the operation.But its toughness of knife blade with ceramic making is poor, can produce certain difficulty with handle when installing.Patent 201320194446.3 discloses a kind of disposable ceramic scalpel, and its shank end is provided with slot, and slot is inverted trapezoidal, and the afterbody design of cutter head is closed with the matching form of slot, and cutter head and slot use interference fit to install.For further enhancing the combination between cutter head and slot, by medical adhesive hydropexis between cutter head and slot.It can thus be seen that, do not ensure that cutter head is securely fixed in slot by interference fit between its cutter head and slot, and use medical adhesive hydropexis can produce certain difficulty when unloading cutter head, therefore there is bigger technological deficiency in mounting means disclosed in this patent.Patent 200410044047.4 discloses the clamping device of a kind of ceramic scalpel, it is made up of handle cap, handle neck, handle neck is contained in the endoporus of handle cap, it is connected by the thread spindle on handle neck and the screwed hole in handle cap are fixing, the left end of handle neck has cone, the left end of the endoporus on handle cap has the taper hole cooperated with the cone on handle neck, and the right-hand member of handle neck has shank body, and the left end shaft of thread spindle is provided with the square clip slot of fixing knife blade in the axial direction.This clamping device one is that structure is complicated, and two is that after handle front end arranges excessively complicated device, its end diameter becomes big, and the surgical field of view of doctor can produce impact, being smoothed out of impact operation when being operated.
Summary of the invention
For the technical problem overcoming current ceramic scalpel blade and handle to produce when being fixed, the present invention is supplied to the ceramic scalpel of a kind of compact conformation, easy installation and removal.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: a kind of ceramic scalpel, including ceramic tip and handle, it is characterised in that: described ceramic tip includes blade part and afterbody, is provided with through hole on the cutter blade of afterbody；The shank body sidepiece of described handle front end is provided with the mounting groove caved in along handle trend, the bottom land of mounting groove is positioned at inside handle handlebody, the shank body of handle front end is divided into upper shank body portion and lower handle portion by mounting groove, it is provided with, in the bottom of upper shank body portion tail end, the rotating shaft pointed in mounting groove, leaves blade bottom rotating shaft and between lower handle portion and insert space；An elastic clip moved towards along handle it is provided with in mounting groove, elastic clip is adjacent to upper shank body portion on the whole, elastic clip is fixed with surface, lower handle portion near one end of rotating shaft, after ceramic tip is positioned at mounting groove inside, rotating shaft is clamped with upper shank body portion through the through hole of ceramic tip afterbody, the afterbody of ceramic tip by elastic clip.
Further, the surface of described elastic clip is provided with some positioning convex strips, and positioning convex strip is vertically arranged with handle trend, is provided with the detent corresponding with positioning convex strip at the back side of ceramic tip afterbody, after ceramic tip is clamped by elastic clip, positioning convex strip is positioned at detent.
Further, being provided with key in mounting groove, key is between elastic clip and lower handle portion, and its front end is hinged with lower handle portion by jointed shaft, and key can rotate into around jointed shaft or produce mounting groove.
The length of described mounting groove and width are consistent with the length of ceramic tip afterbody, width respectively.
Described ceramic tip uses zirconium oxide or aluminium oxide ceramics to be made.
After the ceramic scalpel that the present invention provides uses said structure, the installation of ceramic tip and dismounting become very convenient, and it is firmly combined with being not susceptible to loosen with handle, it is possible to ensure being smoothed out of operation.The thickness of handle front end is basically identical with routine operation handle thickness simultaneously, the surgical field of view of doctor will not be caused obstruction in operation.This ceramic scalpel compact conformation is reasonable, easy to use, can be widely used in all kinds of operation technique.
