AI Technical Summary

Problems solved by technology

Its shortcomings are: (1) it will slip from time to time during the operation grinding, or deviate from the inferior turbinate to the left or right and damage the mucous periosteum of the inferior turbinate
(2) Since each helical thread is in a right-handed self-tapping state when rotating, the adjacent helical grinding teeth are filled with bone meal, resulting in the grinding head becoming blunt

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings. An inferior turbinate grinding drill bit, which is composed of a straight shank 1 and a grinding head 3 integrally connected to the end of the straight shank; the surface of the grinding head 3 has grinding teeth; its characteristic is that the side of the grinding head 3 is a cylindrical surface , the end face is a concave end face 32; the side grinding teeth are long straight teeth;

[0019] Straight handle 1 is long 14cm, and diameter 3mm; Grinding head (3) is long 4.5mm, and diameter 4.5mm, and the concave end face 32 of grinding head is concave the deepest 1.5mm. The side straight grooves are 1mm deep. The minimum tooth width is 0.10~1.5mm. When processing and manufacturing the drill bit of the present invention, no sharp edge should appear at the intersection of each surface, and the transition should be smooth. The straight handle 1 needs to be 5cm long for bei...

Abstract

The invention relates to a grinding drill for inferior turbinate bone, applied to grind inferior turbinate bone of a patient. The drill comprises a straight handle and a grinding head integrally connected onto the end of the straight handle; grinding teeth are provided on the surface of the grinding head; the drill is characterized in that the side surface the grinding head is columniform, the end surface is concave, the grinding teeth on the side surface are long straight teeth; an cut angle at the roots of adjacent straight teeth is an obtuse angle. The invention has advantages of little tunica mucosa trauma, high grinding stability of a drill fork on the inferior turbinate, and the invention is in favor of fluent execution of operations.

Description

technical field [0001] The invention relates to an inferior turbinate grinding drill bit, which is used for grinding patients' inferior turbinates. Background technique [0002] For patients with inferior turbinate hypertrophy or chronic hypertrophic rhinitis, clinical treatment proves that the method of grinding the inferior turbinate bone can be used. The method is: make a 1 cm long straight or L-shaped incision at the front end of the inferior turbinate, insert a 30,000 rpm high-speed electric drill bit into the incision to reach the inferior turbinate bone of the inferior turbinate mucous periosteum, and grind from bottom to top and from front to back , Stop when it reaches the back end of the inferior turbinate bone, and then flush the operation cavity with saline. [0003] The drill bit structure used in the above method is composed of a straight shank and an integrally connected grinding head at the end of the straight shank; the surface of the grinding head has grin...
