Problems solved by technology

[0004] However, due to individual differences, for example, during perineal prostate ablation, the lesion area of ​​some patients may be blocked by the pubic bone
At this time, the needle insertion angle at this site is not parallel to that of other unobstructed sites, and the puncture needle needs to be tilted up or down at a certain angle. The traditional parallel guide hole puncture template cannot insert multiple puncture needles at different angles at the same time. , at this time, the traditional puncture template not only cannot improve the puncture accuracy, but also prevents the puncture needle from tilting up or down to enter the lesion position blocked by the pubic bone, making the operation unable to proceed smoothly

Abstract

The invention relates to an angle adjustable puncture template which comprises a template main body and one or more guide wheel. Each guide wheel is rotatably arranged in the template main body; eachguide wheel is provided with a first guide hole for a puncture needle to pass through; and the axis direction of the first guide hole is changed along with rotation of the corresponding guide wheel. By arranging each guide wheel, the angle adjustable puncture template disclosed by the embodiment of the invention can be adapted to different angles of puncture demands and improves efficiency and puncture accuracy of minimally invasive therapies such as puncture ablation, seed implantation and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an angle-adjustable puncture template. Background technique [0002] Cancer is a major disease that endangers human health. The traditional cancer treatment method and the newly developed thermal ablation therapy characterized by minimally invasive ablation, as well as ablation therapy such as particle implantation, are limited by indications, contraindications, side effects of treatment, thermal effects and other factors, making their clinical application subject to certain limitations. In recent years, with the continuous development of pulsed bioelectricity, electric field pulses have received extensive attention for their non-thermal, minimally invasive biomedical utility, and have been gradually applied to the clinical treatment of tumors. [0003] The above-mentioned minimally invasive therapy often needs to reach the lesion area in the human body through a punctu...
