The orthopaedic orthopedic surgical drill comprises a drill rod, a drill rod handle and a drill bit blade; the drill bit blade is located at the front end of the drill rod, the drill rod handle is connected with the otherend of the drill rod; the top of the drill bit blade is provided with a center point, both sides of the center point are connected with main cutting blades, and the back part of the main cutting blades are provided with secondary cutting blades; the excircle edge of the drill bit blade is provided with cutting blades, and the end surface of the drill bit blade is mounted with finishing blades; the main cutting blades, the secondary cutting blades, the cutting blades and the finishing blades are symmetrically arranged at the top of the drill bit blade. The orthopaedic orthopedic surgical drillhas simple structure, accurate positioning, sharp blade cutting, and small resistance; meanwhile the utility model can effectively reduce the postoperative pain of the patients, and can effectively decrease surface temperature and internal temperature of drilling under different conditions, and also can relieve the fatigue and the burden of the doctors during surgery.
Description
Technical field
The orthopedic orthopaedics surgical bur of this utility model belongs to the machining tool field, particularly relates to the drill bit that uses in a kind of orthopaedics surgical operation.
Background technology
The drill bit that in the orthopaedics surgical operation, uses, require cutting sharp, resistance is little, can effectively reduce the pain of postoperative patient, can effectively reduce drilling surface temperature and internal temperature under the different condition, alleviate fatigue and the burden of doctor when operation, but at the general drill bit that uses the inlet edge chipping of holing appears easily, main cause is the centering effect of drill bit and the not performance of fixed circle effect of cutting edge, and the quality of influence operation is brought certain influence to postoperative rehabilitation.
Summary of the invention
The purpose of this utility model is to provide a kind of accurate positioning, and boring import and outlet edge is smooth, cut sharp, the orthopedic orthopaedics surgical bur that resistance is little.
The purpose of this utility model reaches by following measure, it is by drilling rod, drilling rod handle and drill bit blade are formed, the drill bit blade is at the front end of drilling rod, the drilling rod handle is connected the other end of drilling rod, on the top of drill bit blade the middle apex of the heart is arranged, the both sides of the middle apex of the heart connect main cutting edge, and the main cutting edge rear portion is a front cutting edge, is to cut sword in drill bit blade outer circular edge, the end face of drill bit blade is provided with the polishing sword, main cutting edge, front cutting edge, cut sword, the polishing sword is symmetrical arranged on the top of drill bit blade, and the middle apex of the heart is a cusp, and the center sword plays the centering effect, cusp centering location, accurate positioning.Main cutting edge and front cutting edge mainly play and disperse the cutting resistance effect, cut sharply, and resistance is little.The polishing sword is modified hole wall surface.Cut sword and play fixed circle effect, cut sword and make the boring edge not have chipping, the edge does not have sudden and violent skin and defective such as tears.
This utility model main cutting edge, front cutting edge, cut sword, polishing sword and be provided with, form 8 cutting edges and a middle apex of the heart cutting edge at the top of drill bit blade symmetrical centre point.
This utility model is simple in structure, accurate positioning, boring import and outlet edge are smooth, boring edge quality height can not produce chipping, and the cutting edge cutting is sharp, resistance is little, can effectively reduce the pain of postoperative patient, can effectively reduce drilling surface temperature and internal temperature under the different condition, also can alleviate fatigue and the burden of doctor when operation.
