Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind of neurosurgery scalpel.
Background technology
At present, the scalpel that the clinician uses when doing neurosurgery mainly consists of cutter hub and handle of a knife, in needing to be placed on disinfectant solution before to patient, carrying out neurosurgery, sterilizes, and is easy to like this bump with other operating theater instruments, cause the cutter hub rust, be unfavorable for performing an operation.Notification number: CN201977887U for example; a kind of neurosurgery scalpel is disclosed; front end at handle of a knife is provided with folding, is provided with baffle in folding, utilizes baffle to be protected cutter hub; but when reality is used; baffle is both sides in cutter hub all the time not necessarily, if skew has occurred in the position of baffle, just can't be protected cutter hub; and, in when operation, baffle can hinder doctor's scalpel of taking.
Summary of the invention
Technical assignment of the present utility model is a kind of neurosurgery scalpel provided for above the deficiencies in the prior art.
This utility model solves the technical scheme that its technical problem adopts: a kind of neurosurgery scalpel, comprise handle of a knife and cutter hub, inside at described handle of a knife is provided with sliding tray, described cutter hub is positioned at sliding tray, middle part at described cutter hub is provided with boss, between the port of described boss and sliding tray, is provided with Compress Spring, on described handle of a knife, is provided with chute, be provided with fork shift in described chute, described fork shift is connected with the end of cutter hub.
Described chute is L-shaped.
End at described chute is provided with draw-in groove.During use, can prevent that the doctor from encountering fork shift because of carelessness, cutter hub is rebounded, the process of impact operation.
The utility model has the advantage of simple in structurely, reasonable in design, the time cutter hub can be recoiled in handle in sterilization, avoid the cutter hub rust, do not affect doctor's normal use in operation, can also effectively prevent from recoiling in handle because maloperation causes cutter hub.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, this utility model is described below.
As shown in the figure, a kind of neurosurgery scalpel, comprise handle of a knife 1 and cutter hub 2, be provided with sliding tray 3 in the inside of described handle of a knife 1, described cutter hub 2 is positioned at sliding tray 3, at the middle part of described cutter hub 2, is provided with boss 4, be provided with Compress Spring 5 between the port of described boss 4 and sliding tray 3, be provided with chute 6 on described handle of a knife 1, in described chute 6, be provided with fork shift 7, described fork shift 7 is connected with the end of cutter hub 2.
Described chute 6 is L-shaped.
End at described chute 6 is provided with draw-in groove 8.During use, can prevent that the doctor from encountering fork shift 7 because of carelessness, cutter hub 2 is rebounded, the process of impact operation.
When carrying out disinfection to scalpel, by fork shift 7, cutter hub 2 is recoiled in handle 1, just can avoid cutter hub 2 rusts.During operation, stir fork shift 7 to the draw-in groove 8 of chute 6, make cutter hub 2 stretch out handle 1 and performed the operation, can effectively prevent from like this recoiling in handle 1 because maloperation causes cutter hub 2, and affect doctor's normal use.
