Tumor ablation therapy mechanical device having force/position control protection function

Abstract

The invention provides a tumor ablation therapy mechanical device having a force / position control protection function. The tumor ablation therapy mechanical device comprises a lifting degree-of-freedom module, a force / position control module and a treatment module, wherein the lifting degree-of-freedom module has a vertical lifting degree of freedom, and the lifting degree-of-freedom module is in charge of offering a lifting motion to the treatment module; by virtue of the force / position control module, the force / position control protection function is achieved, and the treatment module can rotate and swing left and right; and the treatment module, which can perpendicularly rotate around an axle and can rotate and swing front and back, has one degree of freedom of rotating and swinging left and right, one degree of freedom of rotating and swinging front and back, one degree of freedom of perpendicularly rotating around the axle and one degree of freedom of lifting. The mechanical device provided by the invention, when applied to ultrasonic ablation therapy, can automatically regulate contract force between a water bag and the abdomen of a patient in accordance with patient's feeling; and corresponding motions are stopped when the contact force reaches preset force, so that safety protection on patient contact is achieved.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to a tumor ablation treatment device, in particular to a tumor ablation treatment mechanical device with a force position control and protection function. Background technique [0002] Uterine fibroids are a common benign tumor in women. When they grow to a certain extent, they need to be treated. Ultrasonic ablation is a method that uses two technical tools, including ultrasonic focused knife and ultrasonic knife. Ultrasonic focused knife can focus energy through human tissue through ultrasonic waves, and generate high temperature to destroy tumor tissue. It is also called ablation. Its characteristic is that the treatment is relatively thorough, and has the advantages of no trauma, no bleeding, and no anesthesia. [0003] After retrieval, Chinese invention patents with publication numbers CN104013444A and CN203988158U relate to a phased array high-intensity focused ultras...
