Abstract
The utility model discloses a medical hand-operated dismountable skull drill which is composed of a handle, a connecting bar and a drill, wherein two ends of the connecting bar are respectively connected with the handle and the dismountable drill, a fixing threaded sleeve is connected to the connecting bar, and the fixing threaded sleeve is externally sleeved with a movable threaded sleeve. When the utility model is used for craniotomy drilling, the size of the opening of the skull can be adjusted according to the size (type) of the external diameter of the dismountable drill, and the length of the projecting portion of the drill can be simultaneously adjusted by adjusting the movable threaded sleeve to control the drilling depth, thereby being favorable for the safety, convenience, duration and application of the skull-drilling operation.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is that a kind of medical detachable awl cranium bores.
Background technology
Present medical awl cranium bores, and its structure ties up to and fixes a connecting rod on its handle, tipped drill on the connecting rod, and perhaps connecting rod adopts screw to fixedly connected with drill bit.During use, use and bore an aperture on this skull that is drilled in patient, to implement operation.But, because boring three parts, this awl cranium links with fixed form, outside diameter is fixed, can't adjust the size of perforate, repeatedly uses back drill bit rust simultaneously, can't continue to use, and has many deficiencies.
The utility model content
This utility model has overcome above-mentioned shortcoming, has proposed a kind of novel detachable awl cranium and has bored.This bore to enlarge awl cranium operation scope of application, and has prolonged service life by bit change more, guarantees safe handling simultaneously.
The technical scheme in the invention for solving the technical problem is: change original fixedly connected drill bit into removably and link, rely on the size of outside diameter (model) simultaneously, adjust the size of perforate.
Medical detachable awl cranium of the present utility model bores to be made up of handle, connecting rod and drill bit, and the two ends of connecting rod connect handle and drill bit respectively.Handle links to each other with connecting rod by straight pin, makes the spill opening in another termination of connecting rod, links with removably with the handle of drill bit.By being connected a fixing swivel nut on swivel nut and the connecting rod, its effect is fixed on drill bit on the connecting rod.Fixedly be with a movable swivel nut outside the swivel nut, its effect is a length of adjusting the drill bit exposed parts.Drill bit is removably and links to each other with connecting rod.
Fixedly swivel nut seesaws along connecting rod, and drill bit is fixed on the connecting rod.Movable swivel nut seesaws along connecting rod, is used to adjust the length of drill bit exposed parts, goes into the degree of depth of intracranial when opening cranium with control.
Advantage of the present utility model is: according to the size of outside diameter (model), adjust and open the size in cranium aperture, thereby strengthen the range of application of this drill bit, drill bit can be changed simultaneously, has prolonged service life, and guarantees safety.

The specific embodiment
Embodiment 1
As shown in Figure 1 to Figure 3, this medical drill bit bore is made up of handle 1, connecting rod 3 and drill bit 6, one end of connecting rod 3 is connected with handle 1, the handle of the other end of connecting rod 3 and drill bit 6 is hard binding, and improvements of the present utility model are to make spill opening 7 at connecting rod 3 other ends, the effect by fixing swivel nut 4 and the handle of drill bit are removably and link, and fixedly being with a movable swivel nut 5 outside the swivel nut 4, are used to adjust the length of drill bit extension.
Handle with drill bit 6 during use is inserted in the spill opening 7 of connecting rod 3, and fixedly swivel nut 4 moves to handle 1 direction on connecting rod 3 again, tightens drill bit 6 is fixed on the connecting rod 3.Described connecting rod 3 is provided with a straight pin 2 that connecting rod 3 can be fixed on handle 1.Movable swivel nut 5 seesaws in the direction of connecting rod 3, with the length of control drill bit 6 sponsons, thus the degree of depth that the control operation needs.
More than medical detachable awl cranium provided by the utility model bored be described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
Claims (2)
1. a medical detachable awl cranium bores, and is made up of handle, connecting rod and drill bit, and the two ends of connecting rod connect handle and drill bit respectively, it is characterized in that: the fixing swivel nut of connection one on the connecting rod, this fixedly swivel nut be with a movable swivel nut outward.
