Description

A kind of scalpel

Technical field

The utility model is related to a kind of medical instruments, and in particular to a kind of scalpel.

Background technology

Scalpel is one of the indispensable instrument for implementing general surgical operation, is mainly used for cutting skin surface and cutting group in operation It knits.Although medical science and technology development of today is very rapid, the type and performance of scalpel oneself through achieving significant progress, Effect of the coventional scalpel in surgical operation is still that can not replace.There are the following problems for existing general surgical operation knife：One, hand The length of art knife cutter hub is changeless, cannot meet the needs of the variation of surgical field, for example small-sized cutter can not be to big face Product depth position is effectively treated；Large-scale cutter can not accomplish perfection in face of small area superficial type wound；And it is frequent Replacement cutter be likely to affect procedure efficiency again, bring life danger to patient；Two, due to the body item for the doctor that operates Part and work habit are multifarious, are unfavorable for giving full play to for doctor's medical level using unified scalpel.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of scalpel.

The purpose of this utility model is achieved through the following technical solutions, a kind of scalpel, including inner hollow Handle of a knife, the scalpel further include the knife tail for being set to handle of a knife end, and the handle of a knife is internally provided with to be extended by knife Caudad point of a knife Internal thread, the knife tail include the part sliding slot that extend into handle of a knife and be rotatably assorted with handle of a knife, the sliding slot from knife tail end to Point of a knife end extends, and the outer wall of the sliding slot is adapted with the inner wall of handle of a knife, and movable block is provided on the sliding slot at knife tail, The side of movable block outer wall coordinates with sliding slot, and the other side of movable block is provided with and the matched external screw thread of internal thread on handle of a knife.

Further, the protrusion extended by knife Caudad point of a knife is relatively set with sliding slot, which is compatible with handle of a knife Cambered surface is provided with protrusion on the protrusion, and position corresponding with protrusion is provided with annular groove on the handle of a knife inner wall.

Further, sliding slot is inserted into movable block, knife for placing scalpel blade, the inner hollow of movable block, blade end Piece end is interference fitted with movable block.

The utility model has the advantage of：

When using scalpel provided by the utility model, operator doctor can as needed operative site actual conditions with And the work habit of oneself carries out arbitrary adjusting to the length of scalpel.

Specific implementation mode

Below with reference to attached drawing, the preferred embodiment of the utility model is described in detail；It should be appreciated that preferably real Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.

A kind of scalpel includes the handle of a knife 1 of inner hollow, which further includes the knife tail 2 for being set to 1 end of handle of a knife, The handle of a knife is internally provided with the internal thread 11 extended by knife Caudad point of a knife, the knife tail include part extend into handle of a knife and with The sliding slot 23 that handle of a knife is rotatably assorted, the sliding slot are extended from knife tail end to point of a knife end, the outer wall of the sliding slot and the inner wall of handle of a knife It is adapted, movable block 3 is provided on the sliding slot at knife tail, side and the sliding slot of movable block outer wall coordinate, movable block The other side is provided with and the matched external screw thread of internal thread on handle of a knife 31.

Sliding slot is for placing scalpel blade 4, and the inner hollow of movable block, blade end is inserted into movable block, in order to make knife Piece will not skid off the opening of point of a knife because of self gravitation effect, and blade end is interference fitted with movable block.

In the present embodiment, it is relatively set with the protrusion 21 extended by knife Caudad point of a knife with sliding slot, which is and handle of a knife The compatible cambered surface of inner wall, is provided with protrusion 22 on the protrusion, position setting corresponding with protrusion on the handle of a knife inner wall There is annular groove.When installation, protrusion is caught in annular groove, and when rotating knife tail 2, protrusion 22 is slided in annular groove.

In use, by rotating knife tail, the sliding slot at the lower end of knife tail is made to be rotated in handle of a knife, to drive on sliding slot Movable block is moved up and down along handle of a knife, and the point of a knife part for the blade being equipped with movable block is extended or retracted.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, it is clear that this field Technical staff spirit and scope of the various modification and variations without departing from the utility model can be carried out to the utility model.This Sample, if these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology range it Interior, then the utility model is also intended to include these modifications and variations.
