Targeted ablation needle control system

Abstract

The invention discloses a targeted ablation needle control system, and relates to the technical field of medical devices. The targeted ablation needle control system comprises a first needle rod withthe expanded end connected with an ablation needle and the long and thin end connected with a needle handle, and a second needle rod sleeving the long and thin end of the first needle rod and connected with the needle handle. A liquid inlet pipe and a liquid outlet pipe are spirally connected between the first needle rod and the second needle rod and communicated with each other. The liquid inletpipe penetrates out of the needle handle to be communicated with a cooling water pump. The end, penetrating out of the needle handle, of the liquid outlet pipe is provided with a water stop clamp andcommunicated with a cooling water tank. The cooling water tank is communicated with the cooling water pump. A microwave coaxial cable connected with the ablation needle is arranged in the first needlerod. A microwave radiation antenna and a first controller which are electrically connected are arranged on the needle handle. The microwave radiation antenna is electrically connected with the microwave coaxial cable. The first controller is electrically connected with a second controller and a control module of the cooling water pump. The problem is solved that the temperature of the ablation needle is transmitted along the outer surface of the needle rods towards the needle handle and burns the normal tissue around the needle rods during the ablation of the ablation needle.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a targeted ablation needle control system. Background technique [0002] At present, the microwave ablation equipment on the market is mainly to set a cooling circulation channel in the needle tube, pass water or gas into the cooling circulation channel, and control the temperature of the rod by means of forced convection heat exchange with the tube wall. During the ablation of the ablation needle, although the cooling circulation channel inside the needle shaft can reduce the temperature of the needle shaft, there is a risk that the temperature of the ablation needle head will be transmitted along the outer surface of the needle shaft to the needle shaft, thereby burning the normal tissues around the needle shaft. Contents of the invention [0003] In view of the above-mentioned prior art, the present invention is to provide a targeted ablation needle control system ...
