Microwave radiofrequency ablation body surface cooling patch

Abstract

The invention provides a microwave radiofrequency ablation body surface cooling patch. The microwave radiofrequency ablation body surface cooling patch comprises a transparent dressing patch, whereina bonding layer is arranged on the back surface of the transparent dressing patch, a containing cylinder which is rolled into a cylindrical structure by a sheet material is arranged on the surface, facing away from the bonding layer, of the transparent dressing patch, and the lower end of the containing cylinder is in heat-seal butt joint with the transparent dressing patch; the containing cylinder comprises an inner cylinder and an outer cylinder which are concentrically arranged, the lower end of the inner cylinder is in heat-seal butt joint with the lower end of the outer cylinder and thenis connected with the transparent dressing patch, the upper end of the inner cylinder is in heat-seal butt joint with the upper end of the outer cylinder, and a plurality of heat-seal lines which areuniformly distributed and arranged in the circumferential direction of the containing cylinder, are in heat-seal in the axial direction of the containing cylinder and enable the outer wall of the inner cylinder to be attached to the inner wall of the outer cylinder are arranged between the cylinder wall of the inner cylinder and the cylinder wall of the outer cylinder; and an inflation port is further formed in the upper end of the inner cylinder and the upper end of the outer cylinder, and a one-way membrane is arranged in the inflation port. The microwave radiofrequency ablation body surfacecooling patch has the advantages that the skin temperature during microwave radiofrequency ablation at a superficial position can be effectively reduced, and skin scalding and ulcer are avoided.

Description

technical field [0001] The invention relates to the field of radiofrequency ablation, in particular to a body surface cooling patch for microwave radiofrequency ablation. Background technique [0002] Microwave curing and radiofrequency ablation are emerging technologies in recent years. Radiofrequency ablation uses a radiofrequency needle to puncture into the tumor and emit radiofrequency waves. The radiofrequency waves oscillate violently in the tumor to generate high temperature and necrosis of tumor cells. To achieve the purpose of treatment, the treatment principle of microwave curing is similar to that of radiofrequency ablation, but the skin will be burned in the superficial position, forming a wound or ulcer, so it is necessary to design a device that reduces burns and avoids ulcers, thereby reducing the number of patients. pain. Contents of the invention [0003] Based on the above problems, the object of the present invention is to provide a microwave radiofrequ...
