Abstract
The utility model relates to a drill bit for drilling coaxial holes with different diameters on bones when the fracture of a long bone is treated. The utility model is formed in the way that the top end of the cutting part of a medical drill bit of a twist drill bit of which the diameter is 4.5 mm is in the length of 2 cm and is reduced to the drill bit with the diameter which is 3.2 mm, and the variable diameter position is in a ladder shape. The drill bit has the advantages of simple refit, convenient use, good effect on fixing a steel plate, reduces operation time, reduces patients' bleeding amount, and decreases the infection rate.
Description
This utility model belongs to the treatment fracture, when using blade plate, and the medical apparatus that uses when coaxial reducing is holed on sclerotin.
At present, the long tubular bone fracture most common therapeutic method is fixed for the open reduction steel plate.Report according to comparatively authoritative in the world " AO " school: be the most effective fixation of performance steel plate, should be when on the backbone, holing at first with the saturating nearly steel plate side seam cortex of the bit drills of diameter 4.5mm, insert the sleeve pipe of external diameter 4.5mm, internal diameter 3.2mm then, change the drill bit of diameter 3.2mm, bore saturating steel plate side seam cortex far away, behind the screw tap mantle fiber of reuse diameter 4.5mm, be screwed into the screw of diameter 4.5mm, backbone and steel plate are connected as a single entity, reach purpose stable between fracture site, this boring method more bit change adds sleeve pipe, and operating procedure is loaded down with trivial details, and operating time is long.
This utility model provides a kind of can overcome the prior art shortcoming, makes the boring once-forming, reduces operating procedure, shortens the coaxial reducing drill bit of operating time.
Above-mentioned purpose of the present utility model is achieved in that with diameter to be the medical spiral bit of 4.5mm, and diameter reduction processes to 3.2mm in the length of the top 2cm of cutting portion, and the reducing place is stepped.
This utility model transformation of the way is easy, the boring once-forming, and can guarantee the concentricity in two holes steel plate contact firmly with key, the operation facility has shortened operating time, thereby has reduced the blood loss of patient when performing the operation, has reduced the infection probability.Better through clinical result of use.
