When scalpel slip after also easily cause patient's secondary injury.
Generally require to prepare the hand of various length and current scalpel major part length is unadjustable, when operation
Art knife, this not only adds the cost of medical apparatus, and frequent tool changing also easily malfunctions during operation, adds the wind of operation
Danger.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of adjustable operation knife, can effectively solve scalpel knife
The exposed easily incised wound medical worker of piece and the problem of cleanup crew, ensures the safety of medical worker and patient, while the length of scalpel
Degree can be adjusted, and avoided frequent tool changing, tried to gain time precious to one for operation patients.
The present invention is achieved in that a kind of adjustable operation knife, including sheath body and handle of a knife, the sheath body
Bottom is connected with handle of a knife by oat tail groove structure, and the setting of described sheath body both sides is fluted, and the handle of a knife is by stretching
Contracting spring is connected with sheath body end, and chute is provided with two closing pieces on the handle of a knife, compression is provided between the closing piece
Spring, skewed slot is provided with described closing piece, brake key is provided with above the sheath body, described brake key includes two transmissions
Bar and at least one locating rod, spring stop is fixed with the drive link, and be provided with returning spring.
Further, described drive link end set has slope.
Further, described returning spring one end is connected with fixed spring stop, the other end and sheath body top
Connection.
Preferably, described brake key includes two locating rods, it is provided with the handle of a knife and locating rod
Two positioning holes coordinated.
Preferably, described sheath body both sides are provided with the first groove, the second groove, the 3rd groove.
The invention has the advantages that：Simple in construction, blade extension can be adjusted, and can be flexibly applied to each
Kind operation, and scalpel blade exposed easily incised wound medical worker and cleanup crew are solve thed problems, such as, so as to ensure that
The safety of medical worker.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
A kind of adjustable operation knife, including sheath body 1 and handle of a knife 7, the bottom of sheath body 1 is coordinated with handle of a knife 7 by oat tail groove structure
Connection, the setting of the described both sides of sheath body 1 is fluted, and the handle of a knife 7 is connected by adjustable spring 2 with the end of sheath body 1, the handle of a knife
Two closing pieces 12 are provided with by chute 14 on 7, are provided with compression spring 11 between the closing piece 12, on described closing piece 12
It is provided with skewed slot, the top of sheath body 1 is provided with brake key 6, and described brake key 6 includes two drive links 9 and at least one
Locating rod, be fixed with spring stop 10 on the drive link 9, and be provided with returning spring 13, described one end of returning spring 13 with
Fixed spring stop 10 is connected, and the other end is connected with the top of sheath body 1.
Described brake key 6 is to include two drive links 9 and the cross-shaped configuration of two locating rods, wherein drive link 9
End set has slope, and the gradient coordinates with the skewed slot gradient on closing piece 12, and two coordinated with locating rod are provided with the handle of a knife 7
Individual positioning hole 15,
The described both sides of sheath body 1 are respectively symmetrically provided with the first groove 3, the second groove 4, the 3rd groove 5.
The present invention have it is standby, partly use, use three kinds of states completely, three kinds of states can be changed mutually.Standby shape
Under state, adjustable spring 2 is relaxed, and blade 8 is contracted in sheath body 1, and closing piece 12 is fastened in the first groove 3, and blade will not outer open trauma
People；When operative space is small, needs partly to use blade, brake key 6 is pressed, returning spring 13 stretches, and drive link 9 moves straight down
Dynamic, under the guide effect on slope, two closing pieces 12 of compressing are compressed to intermediary movements, compression spring 11, and closing piece 12 departs from first
Groove 3, touches forward handle of a knife 7, and handle of a knife 7 when reaching the second groove 4, take-off the brake key 6, is replied by dovetail groove forward slip
Spring 13 is shunk, and brake key 6 resets, and compression spring 11 extends, and closing piece 12 is caught in the second groove 4, and blade section spills sheath body
1；When needing to use blade completely, ibid, closing piece 12 is caught in the 3rd groove 5, when need not use scalpel, or will
When scalpel is transmitted, brake key 6 is pressed, under the elastic force effect of adjustable spring 2, handle of a knife 7 returns to stand-by state, ensures knife
Piece will not exposed injury medical worker.
