Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of obstetrics scalpel.
Background technology
At present, clinically, at the scalpel carrying out to patient using when woman produces operation primarily of cutter head and handle of a knife composition, cutter head and handle of a knife mostly are grafting and fix, when dismantling cutter head after operation is finished using, cutter head need be clamped with pliers cutter head is taken off from handle of a knife, there is following defect in this process, one is a kind of appurtenance pliers of many uses, and two is because cutter head is sharper, easily there is scuffing accident during process cutter head, there is great potential safety hazard.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of obstetrics scalpel, this scalpel structure advantages of simple, and cutter head and handle of a knife convenient separation do not need to use other appurtenances again, handling safety.
A kind of obstetrics described in the utility model scalpel, include handle of a knife, cutter head, push rod and back-moving spring, handle of a knife is made up of upper handle of a knife and lower handle of a knife, described upper handle of a knife and described lower handle of a knife connect and fix, the front end prolongation of described lower handle of a knife is provided with prolonging handle, prolonging handle is provided with chute, the front end of described prolonging handle is provided with fixed leg A, handle of a knife is provided with stopper slot on described, push rod is provided with between described upper handle of a knife and described lower handle of a knife, described push rod front end is embedded in described prolonging handle chute, and slide in described chute, the tail end of described push rod is provided with pushing hands, described pushing hands is stretched out in the stopper slot of described upper handle of a knife, described push rod is provided with limited block, back-moving spring is provided with between described limited block and described lower handle of a knife, the top of described push rod is provided with fixed leg B, described cutter head is provided with locating slot.During installation, upwardly pushing hands, drives push rod to move, is enclosed within the locating slot of cutter head by fixed leg A and fixed leg B, unclamp pushing hands, push rod resets and moves downward under the effect of back-moving spring, and fixed leg A and fixed leg B is stuck in the two ends of cutter head locating slot, thus cutter head and handle of a knife is fixed, during dismounting, upwardly pushing hands, the spacing between fixed leg B and fixed leg A reduces, and cutter head departs from from handle of a knife.
A kind of obstetrics described in the utility model scalpel, simple and reasonable, good stability, by promoting pushing hands, drives push rod fixed with handle of a knife by cutter head under the effect of back-moving spring or be separated, handling safety, easy to use, easy to utilize.
