Description

Scalpel protection device

Technical Field

The utility model relates to the field of medical technology, especially, relate to a scalpel protection device.

Background

The surgical blade is always exposed, career exposure occurs carelessly when the blade is transferred between nursing staff in an operation, so that doctors or nurses are scratched by the blade, and infectious diseases can be transmitted if the doctors or nurses encounter infectious diseases.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a scalpel protection device to solve the current scalpel blade that mentions among the above-mentioned background art and be in naked state, lead to the technical problem of doctor or nurse fish tail easily.

The utility model provides a technical scheme is: the utility model provides a scalpel protection device, includes the handle of a knife, the blade, handle of a knife one side fixed connection blade holder, blade holder one side is equipped with the blade, be equipped with the pivot on the blade holder, pivot swing joint safety cover, be equipped with C type groove on the blade holder, sliding connection stopper in the C type groove, stopper fixed connection safety cover is inboard, one side is equipped with the spring on the blade holder, the spring with safety cover fixed connection.

Preferably, the anti-slip lines are arranged on the knife handle, so that the scalpel is prevented from slipping off from a hand, the friction force between the hand and the knife handle is increased, and the safety is improved.

Preferably, C type groove both ends are equipped with the draw-in groove, the draw-in groove with the stopper phase-match, draw-in groove and stopper can play the joint effect, guarantee the safety cover stability when closing and opening.

Preferably, the protective cover is 2-3 cm longer than the blade, and can completely cover the blade to avoid scratches.

The utility model has the advantages that: the blade can be effectively prevented from being exposed by the protective cover, and the blade is prevented from being scratched; the limiting block slides in the C-shaped groove and is in interference fit with the clamping groove, so that the folding angle of the protective cover can be limited, and a proper operation visual angle is provided. The utility model has the advantages of simple structure, strong practicability and the like.

In the figure: 1. the cutter comprises a cutter handle, 2. a blade, 3. a cutter holder, 4. a rotating shaft, 5. a protective cover, 6. a C-shaped groove, 7. a limiting block and 8. a spring.

Detailed Description

All of the features disclosed in this specification or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations where mutually exclusive features and/or steps are present. Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

As shown in figures 1-4, a scalpel protection device comprises a scalpel handle 1 and a scalpel blade 2, wherein the scalpel handle 1 is provided with anti-skid lines to prevent a scalpel from slipping off a hand, so that friction between the hand and the scalpel handle 1 is increased, safety is improved, one side of the scalpel handle 1 is fixedly connected with a scalpel base 3, one side of the scalpel base 3 is provided with the scalpel blade 2, the scalpel base 3 is provided with a rotating shaft 4, the rotating shaft 4 is movably connected with a protective cover 5, the protective cover 5 is 2-3 cm longer than the scalpel blade 2 and can comprehensively cover the scalpel blade 2 to avoid being scratched by personnel, the scalpel base 3 is provided with a C-shaped groove 6, the C-shaped groove 6 is in sliding connection with a limiting block 7, the limiting block 7 is fixedly connected with the inner side of the protective cover 5, clamping grooves are arranged at two ends of the C-shaped groove 6 and are matched with the limiting block 7, the clamping grooves and the limiting, and a spring 8 is arranged on one side of the cutter holder 3, and the spring 8 is fixedly connected with the protective cover 5.

The utility model discloses a theory of operation is: as shown in fig. 2, the protection cover 5 is in a state when not opened, and at this time, the limiting block 7 (at a black point) is located in the clamping groove at the lower end of the C-shaped groove, and due to interference fit between the clamping groove and the limiting block 7, the spring can be compressed in a clamping state to protect the blade 2, thereby effectively avoiding scratching when a user transfers the scalpel; when the blade 2 needs to be used, force is applied to the front end of the protection cover 5 slightly, namely the force is greater than the force of interference fit between the clamping groove and the limiting block 7, and the blade is lifted upwards, because the protection cover 5 is 2-3 cm longer than the blade 2, a user cannot be injured, the protection cover 5 drives the limiting block 7 to slide in the C-shaped groove under the elastic force action of the spring 8, and the limiting block 7 (at a black point) is located in the clamping groove at the upper end of the C-shaped groove, as shown in fig. 1, so that the blade 2 is in an exposed usable state. The utility model is provided with the protective cover 5 which can effectively prevent the blade 2 from being exposed and scratch; stopper 7 that is equipped with slides in C type groove 6 and with draw-in groove interference fit, can restrict the folding angle of safety cover 5, provide suitable operation visual angle.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
