Tumor ablation needle with blood coagulation function

Abstract

The invention relates to the field of medical apparatus and instruments, in particular to a tumor ablation needle with a blood coagulation function. An existing ablation needle has a single function and can not eliminate a phenomenon of bleeding caused in a surgical puncture and treatment process. The invention provides the tumor ablation needle with the blood coagulation function. The tumor ablation needle comprises a metal needle with a hollow pipe cavity, wherein the front end of the metal needle is a puncture tip; the surface of the middle segment of the metal needle is provided with an insulation coating; a handle is sheathed out of the tail end of the metal needle; the metal needle is provided with a temperature sensor; a heat generation component is sheathed in the pipe cavity of the metal needle and comprises an insulation heat conduction body spliced in the pipe cavity and an electric conduction heat generation element arranged in the insulation heat conduction body; the electric conduction heat generation element is connected with two heating connection points arranged on the tail end of the handle through a guide wire; two heating connection points can be connected withan external high-voltage pulse generator through the guide wire; the high-voltage pulse generator is connected with a computer; and the computer is connected with the temperature sensor. The tumor ablation needle can carry out heating and blood coagulation on the surrounding tissues of a puncture needle passage so as to eliminate the phenomenon of bleeding which generates in the puncture and treatment process.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a tumor ablation needle with blood coagulation function. Background technique [0002] In recent years, electric pulse non-thermal ablation has shown a wide range of clinical application value in the treatment of tumors. Compared with traditional ablation methods, the biggest advantage of using high-voltage pulsed electric field technology is that it is effective on blood vessels, biliary tract, pancreatic duct, nerves, etc. during treatment. For selective protection, especially for the treatment of tumors close to important parts, electric pulse athermal ablation is extremely advantageous. During surgical ablation, it is necessary to perform percutaneous puncture into the treatment site through an electrode needle under the guidance of B-ultrasound or CT images. Patients with poor function have a certain risk. The existing electrode needles have a single function and cannot solve...

Problems solved by technology

[0003] The present invention overcomes the problem that the existing ablation needle has a single function, cannot deal with the bleeding caused by surgical puncture and treatment, and needs to use additional hemostatic devices to bring inconvenience, etc. The present invention provides a tumor ablation needle with blood coagulation function. The needle can rely on its own structural design to heat and coagulate the surrounding tissue of the puncture needle path, so as to solve the bleeding problem during puncture or treatment
