Radiofrequency ablation device for spinal tumor treatment

Abstract

The invention discloses a radiofrequency ablation device for spinal neoplasms operation. The radiofrequency ablation device comprises a radiofrequency electrode for ablating the neoplasms and a conveying component for conveying the radiofrequency electrode to the position of the neoplasms. The conveying component is provided with a bendable part and a telescopic part. The device further comprises a bending control assembly for controlling the bendable part to be bent and a telescopic control assembly for controlling the telescopic component to stretch out or draw back. The bending control assembly and the telescopic control component can convert rotating movement into linear movement so as to control the bendable part to be bent and the telescopic control assembly to stretch out and draw back. The radiofrequency ablation device for the spinal neoplasms operation can position the radiofrequency electrode to the portion where the neoplasms is located precisely, and the neoplasms of different sizes and in different shapes can be ablated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a radiofrequency ablation device for spinal tumor treatment; the device provided by the invention is mainly used in minimally invasive surgery for treating metastatic spinal tumors. Background technique [0002] At present, the domestic methods for spinal metastatic tumors and osteoid osteoma mainly use percutaneous vertebroplasty (PVP) to inject bone cement into the vertebral body through the skin and through the pedicle or pedicle. , the bone cement releases heat during polymerization and solidification, and inactivates both tumor cells and normal cells around the cavity. The key step of percutaneous vertebroplasty is to establish a passage through the skin, pedicle (or outside the pedicle), and inside the vertebral body by puncture method, and then inject bone into the vertebral body through this passage. cement. After the bone cement is injected, its mechanical action can int...

AI Technical Summary

Problems solved by technology

However, due to the differences between the human body's soft tissue and vertebral bone tissue, there are not many studies and applications of this technology in the treatment of spinal metastatic tumors and osteoid osteoma. The main problem is the presence of tumor cells at the edge of the ablation focus residual problems, or significant damage to spinal tissue due to overheating

[0007] Therefore, those skilled in the art are committed to developing a radiofrequency ablation device for spinal tumors, how to solve the above-mentioned problem that the effect of tumor inactivation is not complete, the problem that the tumor cannot be completely inactivated, or to prevent overheating of normal cells and tissue damage, also requiring improved ablation effects, as well as accuracy and controllability issues
