Problems solved by technology

[0005] The purpose of the present invention is to provide a prostate PFA ablation catheter to solve the problem that the existing prostate ablation proposed in the background technology usually uses 3-6 single needles to ablate the enlarged prostate area through the perineal puncture through the template. This method has troublesome operation, Difficulty in puncturing to the target area, long puncture channel and great damage to the patient

Embodiment example 1

[0024] see Figure 1-3 , the present invention provides a technical solution: a prostate PFA ablation catheter, including an outer catheter 1, an inner catheter 2 is sleeved inside the outer catheter 1, and several groups of memory ablation needle groups 3 are arranged on the inner catheter 2 , the memory ablation needle set 3 is composed of several memory ablation electrode needles 4 uniformly arranged on the inner catheter 2 in a circumferential manner.

[0025] Specifically, the memory ablation electrode needle 4 is made of memory alloy, and the cross section of the memory ablation electrode needle 4 is a hemispherical, polygonal or oval flat structure.

[0026] Specifically, the surface of the memory ablation electrode needle 4 has no insulating coating, and the width of the memory ablation electrode needle 4 is 0.1-5mm. The front end of the electrode is a tip, preferably a Mitsubishi structure tip. The electrode needles can be divided into 1 group, 2 groups or more grou...

Embodiment example 2

[0028] see Figure 1-3 , the present invention provides a technical solution: a prostate PFA ablation catheter, including an outer catheter 1, an inner catheter 2 is sleeved inside the outer catheter 1, and several groups of memory ablation needle groups 3 are arranged on the inner catheter 2 , the memory ablation needle set 3 is composed of several memory ablation electrode needles 4 uniformly arranged on the inner catheter 2 in a circumferential manner.

[0029] Specifically, the outer catheter 1, the inner catheter 2 and the memory ablation electrode needle 4 are all biocompatible materials.

[0030] Specifically, when the memory ablation needle group 3 of the inner catheter 2 extends out of the outer catheter 1 , the memory ablation electrode needles 4 are all perpendicular to the inner catheter 2 .

[0031] In practical application, when the PFA ablation catheter of the present invention is applied to prostate ablation, the ablation catheter is inserted from the urethra,...

Abstract

The invention discloses a prostate PFA ablation catheter which comprises an outer catheter, an inner catheter is sleeved with the outer catheter, a plurality of memory ablation needle sets are arranged on the inner catheter, and each memory ablation needle set is composed of a plurality of memory ablation electrode needles circumferentially and evenly arranged on the inner catheter; the memory ablation electrode needle is made of a memory alloy material, and the section of the memory ablation electrode needle is of a hemispherical, polygonal or elliptical flat structure; the surface of the memory ablation electrode needle is not provided with an insulating coating, and the width of the memory ablation electrode needle is 0.1-5 mm; the outer catheter, the inner catheter and the memory ablation electrode needles are made of biocompatible materials; and when the memory ablation needle group of the inner catheter extends out of the outer catheter, the memory ablation electrode needles are perpendicular to the inner catheter. When the PFA ablation catheter is used in an operation, damage is small, important tissues such as blood vessels, nerves and sphincter are not damaged, the sexual function and the urine control function can be reserved, and the operation is simple and rapid.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prostate PFA ablation catheter. Background technique [0002] At present, there are two treatment techniques for prostatic hypertrophy, drug therapy and surgical treatment. Drug treatment has many side effects and is prone to dependence. After taking it for a long time, it will cause great harm to the cardiovascular and cerebrovascular systems and the immune system. Moreover, the treatment is mainly to improve and relieve symptoms, rather than radically cure benign prostatic hyperplasia. [0003] Prostate ablation is a commonly used method in current surgical treatment. Existing prostate ablation generally uses 3-6 single needles to puncture the hypertrophic area of ​​the prostate through the template through the perineum. The problem of long and large patient injury. [0004] Based on this, the present invention designs a prostate PFA ablation catheter. Contents of...
