Currently, cone cranium operation is to treat the common operation of the intracerebral lesions such as hypertensive cerebral hemorrhage, hydrocephalus, with micro-
The advantages that creating, be efficient.Sphenotresia tool used at present includes: hand drill, cranium cone, electronic automatic stop craniotomy drill etc..Above-mentioned hand
Art instrument it is easy to use degree, safely, avoid bone bits retain, in terms of there are respective disadvantages: one, hand drill: skin is soft
Tissue cut, skull bone hole are excessive, and operation is time-consuming, and anesthesia, aseptic condition require high；Two, cranium is bored since its head end is three prismatic,
Skull clast can not be removed, often brings skull clast in brain tissue into, increases damage and postoperative infection chance；Its prevention and treatment is too deep
Sting device is mostly screw, and only frictionally stops cone cranium too deep, and is not easy to quantization drill bit and enters depth；And extracting cranium
There is displacement after cone between skin and skull, causes drainage tube merging difficult, using effect is poor；Three, electronic auto-stop cranium bit: it cannot
Bone bits are removed, the automatic stop protection of bit contact skin often interference skull punching causes operation Back Analysis of Actual Safety Degree decline, electric drill
Maintenance degree is big, battery maintenance frequency is high, disinfection is cumbersome, is easy to appear because the control undue influence emergency treatment of certain link uses,
In addition its cost of equipment is high, often the needs because of equipment disinfection without being able to satisfy linked-together selling.
Existing cone cranium hand drill is other than above-mentioned respective defect, and there are one common shortcomings, that is, hand drill
After cone cranium drilling is completed to exit, since scalp tissue is different with the softness of skull, the retraction displacement of scalp and muscle, often
It can often make the drilling in drilling and skull on scalp misplace, be not easy to follow-up clinical operation.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of the utility model is to provide one kind can be avoided drilling dislocation
And the remaining cone cranium hand drill of intracerebral bone slag, solve drilling and cranium of the cone cranium hand drill in the prior art during exiting on scalp
The technical issues of drilling on bone misplaces.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution is achieved:
A kind of cone cranium hand drill can be avoided drilling dislocation, including drilling rod, one end of drilling rod are provided with handle, drilling rod it is another
One end is provided with drill bit, and sleeve is set on drilling rod, and limit keyway is offered on the inner wall of sleeve, is provided on the outer wall of drilling rod
The positive stop key matched with limit keyway, limit keyway and positive stop key make relatively unrotatable between sleeve and drilling rod；
The sleeve between one end and drill bit of drill bit rounding off be arranged, the sleeve close to handle one
End is withstood in the retention bead being fixed on drilling rod；
External screw thread is machined on the outer wall of the sleeve.
The utility model also has following technical characteristic:
The external screw thread is processed on the outer wall in sleeve close to drill bit.
Scale slot and scale marker line are additionally provided on the outer wall of the sleeve.
The drilling rod and drill bit is hollow structure, and clast storage is provided on the inner wall of the hollow cavity in drilling rod
Deposit slot.
The drill bit is wedging bit or conic drill.
The utility model compared with prior art, has the following technical effect that
Sleeve can be retained on skull by the hand drill of the utility model during exiting, so that drilling and cranium on scalp
Drilling on bone is not in dislocation, greatly facilitates the subsequent operation of cone cranium operation.
The hand drill structure of the utility model is simple, very convenient using carrying, and is convenient for clinical expansion and industrialized production.
