AI Technical Summary

Technical Problem

In existing vertebroplasty surgery, it is very difficult to manually push the split vertebral shaping tool into the lesion vertebral body, time-consuming and labor-intensive, and there is a risk of impulse injury, which increases the difficulty of the operation and the radiation dose to the patient.

Method used

A power drive channel is designed, including a central structure, a sleeve and a clamp. The central structure passes through the intermediate through hole of the clamp. The clamp is connected to the side wall of the sleeve. The power system drives the overall rotation. The variable diameter area of ​​the clamp is pressurized and fixed when it abuts the inner wall of the sleeve to form a high-speed rotating channel, and polishes the bone along the planned path to establish a working channel.

Benefits of technology

Through the use of the power-driven channel device, working channels can be quickly and efficiently established, shortening the surgical time, reducing the difficulty of surgery, reducing radiation damage to patients, and improving the accuracy and efficiency of working channels.

Abstract

The invention discloses a power-driven channel device for vertebroplasty, the channel device is composed of a central structure, a sleeve and a clamping device, the central structure and the clamping device are located in the sleeve, the central structure penetrates through the clamping device through a middle through hole of the clamping device, and the clamping device is connected with the side wall of the sleeve. The central structure comprises a grinding head and a rod body, the rear end of the rod body can be externally connected with a power system, the power system drives the central structure, the sleeve and the clamp holder to rotate, and when the reducing area of the clamp holder abuts against the inner wall of the second-class conical pipe of the sleeve, the interior of the clamp holder pressurizes the central structure and is fixedly connected with the clamp holder and the central structure. Therefore, the central structure, the sleeve and the clamping device are connected into a whole, and under the driving of the power system, the channel device which is integrally formed rotates along a planned path at a high speed to grind sclerotin and establish a working channel, so that time and labor are saved, and the establishment efficiency of the working channel is improved.
