Abstract
The utility model relates to an osteotome bit which is provided with a connection rod and a blade part. A milling groove is arranged in the connection rod; a hole is opened on the rod wall of the connection rod close to the tail end of the milling groove, and the tail end of the milling groove is communicated with the hole; and the diameter of the hole opened on the rod wall of the connection rod ranges from 0.5 millimeters to 2.5 millimeters. By means of the osteotome bit, cooling water can be injected into the bit directly through the connection rod to form a cold cutting mode.
Description
Technical field
This utility model relates to a kind of osteotomy cutter head, belongs to the medical operation instrument.
Background technology
China in Recent Years amputation knife machine industry has obtained very large development, and osteotome is based on surgical operation the needs of accuracy and safety are occurred, and is used for the Medical orthopaedic operation.For satisfying the needs of each position osteotomy, the osteotomy cutter head that present clinical operation is used has miscellaneous; For easy to operate, present osteotomy cutter head gradient cutter head, the sizes and the cutting edge shape also difference along with different use positions of adopting more.
Yet no matter be which type of cutter head, all temperature rising problem can appear inevitably at work.Work under the hot environment and can cause tissue in various degree to burn, the coking tissue is many during cutting, and amount of smoke is large, burning after the cutting, the position is difficult recovers, particularly at the position of neural and blood vessel high concentration, can improve like this risk of operation, increase patient's operation wound.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of osteotomy cutter head is provided.
The technical scheme that realizes this utility model purpose is: there is a groove milling inside of the connecting rod on the osteotomy cutter head; Have an aperture at the terminal close connecting rod bar wall of groove milling, the end of groove milling communicates with aperture.
The described osteotomy cutter head of technique scheme, the hole diameter of opening on its bar wall is 0.5mm ~ 2.5mm.
The utlity model has positive effect:
This utility model can make cooling water be injected on the cutter head, forms cold cut and cuts pattern, can guarantee accuracy and safety maximum in the operation process.At present, its existing more application in the bone surgery of oral cavity.
