Abstract
The utility model discloses a drill bit for orthopedic operations, belonging to a medical tool for an orthopedic department. The drill bit comprises a drill bit handle and a drill bit body, wherein in the position where is near a drill bit tip and occupies 1/5-1/3 length of the whole drill bit, the drill bit gradually and linearly becomes thinner to a drill bit tip direction; the area of the drill bit tip is 1/9-1/4 of the cross section area of the drill bit body; and in the region where the drill bit begins to become thinner, a cutter blade and a bone powder channel are distributed on the side wall of the drill bit. By the adoption of the novel drill bit disclosed by the utility model, the situations that a drill hole becomes larger and the surfaces of bones around the drill hole are scratched can be effectively prevented, so that the secondary damage on a patient in the operation process is relieved, therefore the health of the patient is protected.
Description
Technical field
A kind of bone surgery belongs to the orthopaedic medical treatment apparatus with drill bit.
Background technology
The prior art drill bit follows the drill bit thickness identical from drill bit, and this drill bit is applied in the orthopaedic medical treatment process; At the boring initial stage; Because drill bit can't locate, drill bit is slided near the position that institute should hole, not only cause jewel hole to become greatly easily; And cause the scuffing of jewel hole surrounding bone head surface easily, further damaged patient's health.In addition, the bone bits under boring cause visual disorder to the doctor easily owing to there is not suitable eliminating channel, are unfavorable for patient's treatment.
Summary of the invention
In order to address the above problem, the utility model discloses a kind of bone surgery and use drill bit, this drill bit can effectively avoid jewel hole to become big, and jewel hole surrounding bone head surface is scratched, and alleviates in the operation process patient's secondary injury, has protected patient's health.
This utility model is achieved in that
A kind of bone surgery is used drill bit; Comprise bit sub and drill bit body; Near drill bit and account for the position of whole drill bit 1/5 ~ 1/3 length, drill bit to the direction of drill bit gradually linearity attenuate, the drill bit area is 1/9 ~ 1/4 of a drill bit body cross-sectional area; In the zone that drill bit begins to attenuate, the drill bit sidewall has blade and bone meal passage.
Above-mentioned a kind of bone surgery is used drill bit, and drill bit is planar.
Above-mentioned a kind of bone surgery is used drill bit, and drill bit is taper, and cone angle is 90 ° ~ 150 °.
Prior art is compared; This utility model drill bit is near drill bit and account for the position of whole drill bit 1/5 ~ 1/3 length; Drill bit to the direction of drill bit gradually linearity attenuate, therefore can effectively avoid jewel hole to become big, and jewel hole surrounding bone head surface is scratched; Alleviate in the operation process secondary injury, protected patient's health the patient.
Description of drawings
Fig. 1 is the projection outline figure of this utility model drill bit.
Among the figure: 1 bit sub, 2 drill bit bodies.
The specific embodiment
Below in conjunction with accompanying drawing this utility model specific embodiment is described in further detail.
A kind of bone surgery is used drill bit, comprises bit sub 1 and drill bit body 2, at drill bit body 2 near drill bit and account for 1/5 extension position of whole drill bit body 2; Drill bit to the direction of drill bit gradually linearity attenuate; The drill bit area is 1/4 of drill bit body 2 cross-sectional areas, experiment showed, that this yardstick can locate affected part preferably; Thereby alleviate surface tear, alleviate patient's misery; In the zone that drill bit body 2 begins to attenuate, the drill bit sidewall has blade and bone meal passage 3, and the bone meal passage can be got rid of the bone bits preferably, ensures for performing the operation successfully to increase.Wherein, drill bit is the plane, and figure is as shown in Figure 1 for its projection outline.
