Specifically, a kind ofly be convenient to change and the scalpel of locking scalpel blade and handle of a knife angle, similar with current coventional scalpel, also scalpel blade is comprised and by fastening for the scalpel blade flat strip handle of a knife being installed on its front, in addition, being described below with the difference technical characteristic of coventional scalpel of the scalpel changing also locking scalpel blade and handle of a knife angle is convenient to described in.
The scalpel blade of the scalpel provided for making this utility model patent can change the angle between itself and handle of a knife, described handle of a knife front end is hinged with by universal scalpel blade by the fastening plug-in mounting of the mounting groove on blade knife rest thereon, and described knife rest can rotate around the hinged place with handle of a knife.Like this then can reach by rotating described knife rest the object changing scalpel blade and handle of a knife angle.
To make surgeon can grip scalpel smoothly, surgical operation is carried out to patient in order to be locked by the angle between plug-in mounting scalpel blade thereon and handle of a knife by knife rest locking thus firmly, the hinged place outer surface of described knife rest and handle of a knife front end has the regular polygon boss structure of line centered by jointed shaft axial line, described handle of a knife front end sleeve be equipped with for by described knife rest locking to make the knife rest rotary locking clamping plate that the not revolvable cross section of knife rest and plug-in mounting scalpel blade is thereon U-shaped, described handle of a knife front end has the knife rest rotary locking clamping plate slippage guide ledges for being set with described knife rest rotary locking clamping plate.Described knife rest rotary locking clamping plate slippage guide ledges is positioned at described handle of a knife outer surface, profile is that straight strip is protruding, the central authorities of described knife rest rotary locking clamping plate have the slippage gathering sill suitable with described knife rest rotary locking clamping plate slippage guide ledges, and described knife rest rotary locking clamping plate are set on described knife rest rotary locking clamping plate slippage guide ledges by its slippage gathering sill.The length of the slippage gathering sill of described knife rest rotary locking clamping plate is greater than the length of the described knife rest rotary locking clamping plate slippage guide ledges of handle of a knife outer surface thus guarantees that described knife rest rotary locking clamping plate can carry out slippage along the described knife rest rotary locking clamping plate slippage guide ledges of handle of a knife outer surface.For no reason come off from handle of a knife to prevent described knife rest rotary locking clamping plate, after described knife rest rotary locking plywood sleeve is loaded in described knife rest rotary locking clamping plate slippage guide ledges, utilizes the two panels external diameter being anchored on described knife rest rotary locking clamping plate slippage guide ledges two ends to be greater than the flat shim of the groove width of described slippage gathering sill and screw and described knife rest rotary locking clamping plate are limited on handle of a knife make it be unlikely to drop from handle of a knife.In order to make described knife rest rotary locking clamping plate can by teamed with the angle between locking knife rest and handle of a knife for two sides of the relative edge of the regular polygon boss of knife rest, the both sides up and down of described knife rest rotary locking clamping plate all have the boss opposite side locking clamping plate to handle of a knife outer surface direction bending projection, when the knife rest direction of described knife rest rotary locking clamping plate to handle of a knife front end is passed, two sides of a pair relative edge of the described regular polygon boss of knife rest can sandwich thus the related described knife rest of described regular polygon boss cannot be rotated around the hinged place of knife rest and handle of a knife by two described boss opposite side locking clamping plate.Gap between described knife rest rotary locking clamping plate slippage guide ledges on the conduit inwall of the slippage gathering sill of described knife rest rotary locking clamping plate and handle of a knife is little not too much thus guarantee that described knife rest rotary locking clamping plate can carry out slippage along described knife rest rotary locking clamping plate slippage guide ledges smoothly, simultaneously also large not too much thus guarantee that described knife rest rotary locking clamping plate can not rotate with the rotation of the regular polygon boss of the knife rest of sandwiched locking easily.Like this then when described knife rest rotary locking clamping plate forward slippage the regular polygon boss of knife rest is teamed by the boss opposite side locking clamping plate of upper and lower both sides after, described knife rest and on scalpel blade namely cannot rotate, namely angle between described scalpel blade and handle of a knife is fixed, as long as and make the slippage backward of described knife rest rotary locking clamping plate, make after the regular polygon boss of knife rest departs from the double team of boss opposite side locking clamping plate of the upper and lower both sides of described knife rest rotary locking clamping plate, described knife rest can rotate freely, just can be adjusted by swivelling tool-holder and change the angle between scalpel blade and handle of a knife.And when the angle of scalpel blade and handle of a knife adjusts complete, only need again by described knife rest rotary locking clamping plate forward slippage the regular polygon boss of knife rest can be reappeared the angle between locking knife rest and handle of a knife by the boss opposite side locking clamping plate of upper and lower both sides are teamed thus are fixed up by the angle between scalpel blade and handle of a knife, then surgeon just successfully can carry out surgical operation with scalpel.
In order to ensure the regular polygon boss of scalpel knife rest when normally using at ordinary times by the firm clamping locking of described knife rest rotary locking clamping plate, described knife rest rotary locking clamping plate are welded with one piece of spring limiting board towards the inner surface rear end of described handle of a knife, described handle of a knife outer surface has the spring inserting groove inserting a spring, described spring limiting board stretches among described spring inserting groove, described spring one end props up described spring limiting board, the other end props up the end of the described spring inserting groove of handle of a knife outer surface, its elastic force keeps the trend of two sides of a pair relative edge of the regular polygon boss of the teamed described knife rest of boss opposite side locking clamping plate described knife rest rotary locking clamping plate being made the upper and lower both sides of described knife rest rotary locking clamping plate along described knife rest rotary locking clamping plate slippage guide ledges to the front end slippage of handle of a knife.As long as like this then at ordinary times cannot by the slippage backward of described knife rest rotary locking clamping plate, under the elastic force effect of spring, described knife rest rotary locking clamping plate will be in the position clamped two sides of a pair relative edge of the regular polygon boss of knife rest always, thus the angle firmly between locking scalpel blade and handle of a knife, to guarantee that surgeon can grip scalpel normally for patient and carry out surgical operation.And surgeon is when the scalpel holding with a hand this utility model patent and provide carries out surgical operation for patient, unless deliberately, otherwise its to scalpel grip normally can not produce make described knife rest rotary locking clamping plate backward slippage to remove the active force of the locking of the regular polygon boss of cutter setting frame, therefore this utility model patent provides scalpel is completely can normal use as common scalpel, and the angle that can also suitably change compared with coventional scalpel between scalpel blade and handle of a knife, to facilitate surgeon to the surgical operation at some particular pathologies positions.
Drop in the spring inserting groove handle of a knife to prevent described spring, the welding position of described spring limiting board has certain distance to drop in described spring inserting groove to prevent spring apart from described knife rest rotary locking clamping plate towards the edge of the inner surface rear end of described handle of a knife, and outside the end of described spring inserting groove, also fastening cover is equipped with one piece of spring bumper cover and prevents described spring from dropping in described spring inserting groove further.Like this then one end of spring has described knife rest rotary locking clamping plate to block, and can not drop out after within the described spring inserting groove that the other end has described spring bumper cover to block can to ensure it to be plugged on handle of a knife in conduit.
