Medical multifunctional drill bit protector

Abstract

A medical multifunctional drill bit protector comprises an inner tube and an outer tube, the inner tube is provided with locking holes, square locking holes and an inner tube scale, the outer tube hasa locking window, and the locking window is provided with a scale; the inner tube is matched in the outer tube, and can be pulled and moved; and the locking holes and the square locking holes are matched with depth limiting rods, and the depth limiting rods can be flexibly inserted in and taken out of the locking holes and the square locking holes. The medical multifunctional drill bit protectorhas the following advantages: the depth of the inner tube entering the outer tube, which is a difference between scale values before and after hole drilling, is used as the hole drilling depth, so thedepth determination result is accurate and reliable, the inconvenience and unreliability of the determination of the depth by a depth measuring ruler are avoided, and the operation time is saved; andthe hole drilling depth can be directly locked through the reliable fixation of the depth limiting rods by an assistant, so a drilling bit is avoided from stabbing too much or too deep during drilling of opposite cortexes, thereby the safety of the operation is improved.

Description

technical field [0001] The invention relates to a medical drill bit protection device, in particular to a medical multifunctional drill bit protection device. Background technique [0002] At present, in the known open reduction plate internal fixation operation for extremity fractures, it is necessary to use an electric drill to drill holes on the bone and measure the drilling depth to select a steel nail of appropriate length for fixation. The drill bit protection commonly used in the drilling process cannot measure the drilling depth. After the drilling is completed, use the depth gauge to measure the drilling depth and select the screw of the corresponding length. Contents of the invention [0003] In order to solve the problem that the drill bit protection commonly used in the drilling process cannot measure the drilling depth, after the drilling is completed, the depth gauge should be used to measure the drilling depth and then the screw of the corresponding length s...

Problems solved by technology

[0003] In order to solve the problem that the drill bit protection commonly used in the drilling process cannot measure the drilling depth, after the drilling is completed, the depth gauge should be used to measure the drilling depth and then the screw of the corresponding length should be selected. In addition to protecting the surrounding soft tissue and limiting the drilling depth, the designed and manufactured medical multifunctional drill protector can also measure the drilling depth.
