Scalpel medical in the market and blade; great majority do not have safety guard; blade is exposed; very easily incised wound medical worker and cleanup crew; easily causing medical worker and the threat of cleanup crew's blood-borne pathogens infection, scalpel also very easily causes patient's secondary injury after slipping even sometimes.
And current scalpel major part length is unadjustable, generally requires the scalpel preparing various length when operation, this not only adds the cost of medical apparatus, and when performing the operation, frequent tool changing also easily makes mistakes, add the risk of operation.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of adjustable operation cutter, the problem that can effectively solve the exposed easy incised wound medical worker of scalpel blade and cleanup crew, ensure the safety of medical worker and patient, the length of scalpel can regulate simultaneously, avoid frequent tool changing, try to gain time precious to one for surgical patient.
This utility model is achieved in that a kind of adjustable operation cutter, including sheath body and handle of a knife, described sheath body
Bottom and handle of a knife are connected by oat tail groove structure, described sheath body both sides are provided with groove, described handle of a knife is connected with sheath body end by coil tension spring, described handle of a knife is provided with two lock dogs by chute, is provided with compression spring between described lock dog, described lock dog is provided with skewed slot, described sheath body is provided above brake key, described brake key comprises two drive links and at least one location bar, described drive link is fixed with spring stop, and is provided with returning spring.
Further, described drive link end is provided with slope.
Further, described returning spring one end is connected with fixing spring stop, the other end and sheath body top
Connect.
As preferably, described brake key includes two location bars, described handle of a knife is provided with and positions bar
The hole, two location coordinated.
As preferably, described sheath body both sides are provided with the first groove, the second groove, the 3rd groove.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of adjustable operation cutter, including sheath body 1 and handle of a knife 7, it is connected by oat tail groove structure with handle of a knife 7 bottom described sheath body 1, described sheath body 1 both sides are provided with groove, described handle of a knife 7 is connected with sheath body 1 end by coil tension spring 2, described handle of a knife 7 is provided with two lock dogs 12 by chute 14, compression spring 11 it is provided with between described lock dog 12, described lock dog 12 is provided with skewed slot, described sheath body 1 is provided above brake key 6, described brake key 6 comprises two drive links 9 and at least one location bar, described drive link 9 is fixed with spring stop 10, and it is provided with returning spring 13, described returning spring 13 one end is connected with fixing spring stop 10, the other end is connected with sheath body 1 top.
Described brake key 6 is the cross-shaped configuration including two drive links 9 and two location bars, and wherein drive link 9 end is provided with slope, and the gradient coordinates with the skewed slot gradient on lock dog 12, described handle of a knife 7 is provided with and positions the hole 15, two location that bar coordinates,
Described sheath body 1 both sides are respectively symmetrically and are provided with first groove the 3, second groove the 4, the 3rd groove 5.
This utility model has standby, part use, completely three kinds of states of use, and three kinds of states can be changed mutually.Under resting state, coil tension spring 2 relaxes, and blade 8 is contracted in sheath body 1, and lock dog 12 is fastened in the first groove 3, and blade will not expose hurts sb.'s feelings；When operative space is little, when needing part to use blade, press lower brake key 6, returning spring 13 stretches, and drive link 9 moves straight down, under the guide effect on slope, oppress two lock dogs 12 to intermediary movements, compression spring 11 is compressed, and lock dog 12 departs from the first groove 3, touches forward handle of a knife 7, handle of a knife 7 is by dovetail groove forward slip, when arriving the second groove 4, take-off the brake key 6, returning spring 13 shrinks, brake key 6 resets, compression spring 11 extends, and lock dog 12 snaps in the second groove 4, and blade section spills sheath body 1；When needs use blade completely, ibid, lock dog 12 is snapped in the 3rd groove 5, when using scalpel, when maybe being transmitted by scalpel, press lower brake key 6, under the elastic force effect of coil tension spring 2, handle of a knife 7 returns to resting state, it is ensured that blade will not expose injury medical worker.
