Description

Novel surgical knife

Technical Field

The utility model relates to a medical appliance, in particular to a novel surgical scalpel.

Background

Since the electric knife is widely used, the current surgical knife is mainly used for cutting the skin, the traditional surgical knife comprises a knife handle 1 and a knife edge 2 (see fig. 1), the cutting depth is not well controlled during the skin cutting, particularly, a plurality of cuts only need to cut the dermis, the thickness of the dermis is about 0.1-3mm according to different parts, and even a very experienced surgeon cannot ensure that only the dermis is cut uniformly and accurately. Beginners often make multiple cuts in the skin, causing some unwanted damage.

Disclosure of Invention

An object of the utility model is to provide a novel surgical knife, can adjust the length that exposes of cutting edge as required.

Novel surgical knife, including handle of a knife and the cutting edge of setting at the handle of a knife front end the guide slot has been seted up along length direction in the handle of a knife be equipped with the separation blade in the guide slot, seted up a plurality of locating holes along length direction on this separation blade, the draw-in groove has been seted up to a side of guide slot, and the upper and lower edge of this draw-in groove has the sawtooth groove be provided with the locking block in the draw-in groove, the locking block is fixed on the locating hole of separation blade through its inboard reference column, the upper and lower both sides of locking block with the sawtooth groove cooperation.

Preferably, the front end of the blocking piece is provided with a folded limiting part.

Preferably, the bottoms of the left end and the right end of the locking block are provided with inclined plane notches.

Preferably, the outer side surface of the locking block is provided with anti-slip threads.

Preferably, the positioning column of the locking block is in interference fit with the baffle positioning hole.

The utility model discloses simple structure, convenient to use can adjust the length that exposes of cutting edge as required at will to accurate, and the even skin that opens of degree of depth when guaranteeing to cut the skin, the vice damage when preventing to cut the skin.

Detailed Description

The present invention will be further explained in detail with reference to the drawings and examples, which are only used for explaining the present invention and do not limit the scope of the present invention.

The novel surgical scalpel shown in fig. 2, 3 and 4 comprises a scalpel handle 1 and a cutting edge 2 arranged at the front end of the scalpel handle, wherein a guide groove is formed in the scalpel handle along the length direction, a blocking piece 3 is assembled in the guide groove, and the length of the guide groove is greater than that of the blocking piece. The stopper 3 is provided with a plurality of positioning holes 301 along the longitudinal direction. A clamping groove is formed in one side face of the guide groove, and a sawtooth groove 101 is formed in the upper edge and the lower edge of the clamping groove.

The locking piece 4 is arranged in the clamping groove, the upper side and the lower side of the locking piece are matched with the sawtooth grooves, the locking piece is fixed on two corresponding positioning holes of the separation blade through two positioning columns 401 on the inner side of the locking piece, and the positioning columns and the positioning holes are in interference fit, so that the separation blade is guaranteed against loosening. The outer side surface of the locking block is provided with uneven anti-slip lines 402.

Referring to fig. 5, the front end of the blocking sheet is provided with a vertically folded limiting portion 302, and the limiting portion 302 is widened relative to the rear portion of the blocking sheet, so that the limiting portion can completely shield the cutting edge. When the operation is carried out, the limiting part at the front end of the baffle sheet is abutted against the body surface, so that the incision with the same depth can be formed.

Referring to fig. 4, the bottom of the left end and the right end of the locking block 4 are provided with inclined plane notches 403, so as to facilitate the locking block to be pulled out by pinching the inclined plane notches at the two ends of the locking block with fingers, thereby removing or adjusting the position of the blocking piece.

When the scalpel is used, the length of the guide groove extending out of the separation blade is adjusted as required, so that the size of the knife edge exposed from the front end of the separation blade meets the requirement, the locking block is pressed into the clamping groove of the scalpel handle, the positioning column of the locking block is inserted into the positioning hole of the separation blade, the separation blade is fixed, and the scalpel is convenient and fast to install.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
