A medical intelligent auxiliary bone drill

Abstract

A medical intelligent auxiliary bone drill, comprising: a fixed seat part, an electric rotation part, an expansion mechanism and a telescopic mechanism, the electric rotation part is slidably installed on the fixed seat part; the expansion mechanism is installed in the telescopic mechanism; the lower fixed ring and the upper fixed ring The inner side is provided with a rubber ring; the present invention connects the lower fixing ring and the upper fixing ring of the fixed seat part, and clamps the arm or leg that needs to be punched through the lower fixing ring and the upper fixing ring; prevents the drilling from being crooked, and then improves Improve the quality of work; By setting the positioning ruler and the clamping block, manually pulling the clamping block and then adjusting the position of the positioning ruler to locate the drilling depth of the electric rotation part, so as to prevent the patient from being injured due to excessive drilling due to uneven force.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical intelligent auxiliary bone drill. Background technique [0002] Bone drill is a commonly used bone drilling instrument, which is often used in neurosurgery, cardiothoracic surgery, orthopaedics, burns, etc. The existing bone drills are usually electric, and the rotation of the drill bit is controlled by a motor to drill the corresponding bone. However, due to the lack of supporting auxiliary devices during operation, the phenomenon of drilling deviation is easy to occur, and then medical accidents occur. [0003] For example: Chinese invention patent No. 2017109552805 discloses a medical bone drill, which includes: a handle, a drill body and a drill bit, the handle and the drill bit are respectively fixed on the drill body, the drill bit is provided with a motor, and the drill bit is provided with The fixed seat and the drill bit are detachably connected, the s...

Problems solved by technology

[0002] Bone drill is a commonly used bone drilling instrument. It is often used in neurosurgery, cardiothoracic surgery, orthopedics, burns, etc. Existing bone drills are usually electric, and a motor controls the rotation of the drill bit and then drills on the corresponding bone. Drilling, but due to the lack of supporting auxiliary devices during operation, drilling deviation is easy to occur, and medical accidents occur

[0003] For example: the Chinese invention patent with the patent number of 2017109552805 discloses a medical bone drill, which includes: a handle, a drill body and a drill bit, the handle and the drill bit are respectively fixed on the drill body, the drill bit is provided with a motor, and the drill bit is provided with The fixed seat and the drill bit are detachably connected. The fixed seat includes a recessed fixed seat shell, and the middle of the fixed seat shell is provided with a rotating rod and a motor connection. When drilling with a medical bone drill, it is easy to cause drilling deviation, which in turn causes medical accidents

[0004] After further searching, it was found that the Chinese invention patent with the patent number of 2018102773962 discloses a medical intelligent drilling guide device, which includes a machine base, a support frame is fixed on the side of the machine base, and an open source single-chip microcomputer and a wireless computer are respectively installed on one side of the support frame. Control device, an adjustment mechanism is installed on the other side of the support frame, a medical bone drill and a positioning device are respectively installed at the end of the adjustment mechanism, and a pressure monitoring device is installed at the connection between the adjustment mechanism and the medical bone drill, and the input end of the open-source single-chip microcomputer The output end of the external power supply is electrically connected, and the output end of the open-source single-chip microcomputer is electrically connected to the input end of the medical bone drill. The medical intelligent drilling guide device locates the working position of the medical bone drill through the positioning device; but the invention uses the open-source single-chip microcomputer and the Controlled by a wireless control device, when the program is wrong or the power is accidentally cut off, the drilling deviation will still be caused. Therefore, there is an urgent need for a medical intelligent auxiliary bone drill that can be operated manually and mechanically while ensuring the accuracy of the drilling operation to solve the above problems.
