Abstract
The utility model discloses a novel surgical knife handle, and belongs to the technical field of medical apparatuses and instruments. The novel surgical knife handle comprises a knife handle body, wherein the knife handle body is provided with a limiting boss and a sliding groove, the sliding groove is a trapezoidal groove, a U-shaped sliding rod is installed in the sliding groove, the front end of the U-shaped sliding rod is of an arc shape, a threaded hole is formed in the front end of the U-shaped sliding rod, a ball stud is screwed into the threaded hole through threads, an upper sliding groove is formed in the part, above the sliding groove, of the knife handle body, a threaded rod in the middle of the bulb stud can slide front and back in the upper sliding groove, the shape of the limiting boss is basically the same as the shape of a fixing groove of a common surgical blade except that the top end of the limiting boss is slightly longer than the fixing groove of the surgical blade, a limiting groove is formed in the slightly longer part of the top end of the limiting boss, and the whole limiting boss has the same shape as the surgical blade fixing groove except for the slightly longer part at the top end of the limiting groove. The novel surgical knife handle solves the problems that in the process of assembly and disassembly between a surgical blade and a knife handle, overlarge manual force is applied, operation is difficult, and the potential safety hazards usually exist.
Description
Technical field
This utility model relates to a kind of novel operation handle of a knife, belongs to technical field of medical instruments.
Background technology
The scalpel that current basic surgical operation uses is made up of blade and handle of a knife two parts, and blade is disposable, and handle of a knife is not.The model of conventional blade holder is J11010 3#, J11020 3L#, J11030 4# and J11040 4L#.When in blade holder technical specification, major requirement handle of a knife coordinates with knife blade, dismounting should be light.The installation of standard is a hand-held handle of a knife, another for hands needle forceps (needle holder) clamp blade, embed the recess of handle of a knife front end, then use needle forceps (needle holder) that blade is clipped and can be used.But in actual use, while using above-mentioned handle of a knife to coordinate with blade, dismantle not light.Because while installation there is reason that could be fixing after slight deformation in blade; cause setter to go to install by larger power; in anatomy experiment class hour, student often can scratch hands; be easy to make people to produce fatigue and carry out repetitive operation in operating set-up procedure in hospital; decrease in efficiency, the used time is long.For this sport technique segment of racing against time of operation, obviously also there are improved needs in this blade holder.
Summary of the invention
The deficiency existing in order to solve above-mentioned prior art, this utility model provides a kind of novel operation handle of a knife, and this blade holder meets the technical specification of blade holder, without making blade generation deformation can install knife blade.
This utility model solves the technical scheme that its technical problem adopts: a kind of novel operation handle of a knife comprises handle of a knife, handle of a knife is provided with positive stop lug boss and chute, chute is a dovetail groove, U-shaped slide bar is installed in chute, U-shaped slide bar front end is camber, which is provided with a screwed hole, and ball stud is threaded in screwed hole, chute top handle of a knife is provided with a upper hopper chute, and ball stud middle screw rod can be slided front and back in upper hopper chute; Positive stop lug boss shape and conventional knife blade holddown groove shape are basic identical, just the holddown groove of knife blade is slightly longer than on top, slightly long part below, positive stop lug boss top is provided with a stopper slot, removes the slightly long part in stopper slot top, and whole positive stop lug boss is identical with knife blade holddown groove shape.
The vertical center of described stopper slot 7 is the vertical center of whole handle of a knife 5.
Described U-shaped slide bar 2 one end slide bars are longer than other end slide bar.
The beneficial effects of the utility model are: this utility model solved knife blade coordinate with handle of a knife in unloading process artificial too much firmly, bad operation, easily there is the problem of potential safety hazard, simple in structure, easy to operate, when installation there is not deformation in blade, improve work efficiency, ensure operator's safety, reasonable in design, reusable.
