Description

Universal scalpel

Technical field

This utility model belongs to medical surgical instrument, specifically a kind of universal scalpel.

Background technology

Scalpel is a kind of very important operating theater instruments in surgical operation, and at present, the scalpel using clinically, is comprised of handle of a knife and blade, and blade is connected with the head end of handle of a knife, and blade angle can not regulate.In operation, when needs cuttings organize position of living in comparatively narrow and small time, due to the obstruction of handle of a knife, cutter head cannot contact need the tissue of cutting, handle of a knife also can hinder doctor's sight line sometimes, cutting is got up comparatively hard, even cannot cut, cause operating time to extend, increase corrective surgery risk, in order to save rescue time, doctor often takes off blade, hands pinch blade operates under narrow and small environment, and careless slightly easy incised wound doctor, causes infection.

Utility model content

This utility model is that the technical scheme that its technical problem of solution is taked is, design a kind of universal scalpel, its structure comprises: handle of a knife, blade and universal joint, described handle of a knife is cylindrical knife shank, surface is provided with anti-slip veins, described universal joint is by ball cover, hinged ball and ball cap form, on hinged ball, be connected with dwang, the inner chamber of ball cover and ball cap is and the corresponding spherical groove of hinged ball sphere, the crown place of ball cap offers rotation hole, described hinged ball is arranged in the spherical inner chamber of ball cover and ball cap formation actively, between ball cover and ball cap, be threaded connection fixing, in the rotation hole of described dwang from ball cap, stretch out, described ball cover is connected with the front end of handle of a knife, in handle of a knife, be provided with an internal thread through hole, one end opening of this internal thread through hole is positioned at the rear end of handle of a knife, other end opening is connected with the spherical inner chamber that ball cover and ball cap form, at described internal thread through hole female thread, be connected with a locking screw, the end of locking screw holds out against described hinged ball, described blade is connected on described dwang, the surface of blade is provided with scale value, also comprise an illuminator, this illuminator is comprised of battery, switch, clip, LED lamp, and described battery, switch, LED lamp are sequentially composed in series loop, and described battery and switch are arranged on described handle of a knife, clip is on described blade, and LED lamp is fixed on the clamp holder of clip.

The beneficial effects of the utility model: owing to being provided with a universal joint between handle of a knife and blade, can blade carry out angular adjustment, specifically first unclamp locking screw, after blade angle regulates, rotary locking screw holds out against the hinged ball fixed blade position in universal joint again, easy to operate, use flexibility and reliability, especially the cutting operation under small space, effective speed is fast, can obviously save operating time, the illuminator arranging, structure is ingenious, utilize clip that LED lamp is fixed on blade, doctor can be according to actual needs by the clamping position at needs of LED lamp, or even on patient tissue, LED lamp is auxiliary to be irradiated, can make doctor carry out more accurately hands art, further improved operation quality.
