Problems solved by technology

Although this automatic bone drilling device greatly saves the operation time, not only is the stability not high due to the too long operating part of the Kirschner wire, but also the clamping method is easy to be unstable. It is a disposable instrument, and the bolt disassembly is too c

Abstract

The invention discloses an automatic bone drilling device. The device comprises a feeding mechanism (3), a rotating mechanism (2) installed on the feeding mechanism (3), and a Kirschner wire (1) installed on the rotating mechanism (2); and the rotating mechanism (2) has a hollow structure, the Kirschner wire (1) is fixed after being inserted into the rotating mechanism (2), and the insertion depthof the Kirschner wire (1) is adjustable. According to the device, the rotating mechanism is set as the hollow structure, so that the exposed length of the operation part of the Kirschner wire can beadjusted, and the device is simple and convenient to operate without being assembled and disassembled by bolts; and in addition, the feeding mechanism and the rotating mechanism of the device are improved in structure, the volume and mass are greatly reduced, and the device can realize fully automatic operation of spinal bone drilling.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an automatic bone drilling device. Background technique [0002] Vertebral body enhancement is a technique that injects bone cement or artificial bone into the diseased vertebral body through percutaneous puncture under the guidance of medical imaging images to strengthen the vertebral body. Most of the existing spine drilling devices are manual, and the manual puncture device includes a puncture needle, a working channel, a guide pin and a hand drill, wherein the puncture needle includes a needle tube and a needle inserted in the needle tube. During the puncture process, the doctor needs to cut an incision on the patient's skin first; then insert the puncture needle into the lesion of the patient, then take out the needle and keep the needle tube; then insert the guide needle into the needle tube of the puncture needle, keep the guide needle and take out the needle tube of the...
