Microwave ablation needle and microwave ablation therapeutic instrument thereof

Abstract

The invention discloses a microwave ablation needle and a microwave ablation therapeutic instrument thereof. The microwave ablation needle comprises an ablation needle body, a depth adjusting device,a first angle adjusting device, a second angle adjusting device, a bottom plate and a therapeutic instrument body, wherein the ablation needle body is slidably connected to the inner part of the depthadjusting device, and the needle tip of the ablation needle body is arranged downwards; and the lower end of the depth adjusting device is arranged in the upper end of the first angle adjusting device, and the second angle adjusting device is arranged behind the first angle adjusting device. The depth adjusting device, the first angle adjusting device and the second angle adjusting device can automatically and accurately control the depth and angle of the ablation needle inserted into a focus of a tumor, the accuracy of the position of the ablation needle is guaranteed, then a good treatmenteffect is guaranteed, besides, adjustment of the depth and angle of the ablation needle is reduced, and the operation time is shortened. The work intensity and technical and psychological quality requirements of doctors are reduced, and fear and worry of patients and family members are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, the invention relates to a microwave ablation needle and a microwave ablation treatment instrument thereof. Background technique [0002] At present, microwave ablation needles and microwave ablation therapy instruments are more and more used in tumor ablation due to their remarkable curative effect, easy operation, and small wounds; Under the monitoring or guidance of the guiding device, the ablation needle is manually inserted into the center of the tumor lesion. The angle and depth of the ablation needle insertion need to be manually controlled by the doctor, which is difficult to control and requires a high technical level of the doctor. When the technical level is not enough, when the ablation needle insertion angle or depth error is large, manual adjustment is required, and the operation time is longer; especially when the ablation needle angle error is large,...

AI Technical Summary

Problems solved by technology

[0002] At present, microwave ablation needles and microwave ablation therapy instruments are more and more used in tumor ablation due to their remarkable curative effect, easy operation, and small wounds; Under the monitoring or guidance of the guiding device, the ablation needle is manually inserted into the center of the tumor lesion. The angle and depth of the ablation needle insertion need to be manually controlled by the doctor, which is difficult to control and requires a high technical level of the doctor. When the technical level is not enough, when the ablation needle insertion angle or depth error is large, manual adjustment is required, and the operation time is longer; especially when the ablation needle angle error is large, the reinsertion of the ablation needle requires a stable psychological quality of the doctor. If there is another problem with the insertion angle or depth, it needs to be adjusted again, and the operation time will be further extended, and the doctor's work intensity will increase, and the patient and family members will be afraid and worried; Can effectively solve the above problems, therefore, it is necessary to propose a microwave ablation needle and a microwave ablation therapy instrument thereof, to at least partly solve the problems existing in the prior art
