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

Abstract

An embodiment of the invention relates to an adjustable puncture template. The adjustable puncture template comprises a rotary template assembly and a template frame body, wherein a through hole penetrating through a front surface and a rear surface of the template frame body is formed in the template frame body; the rotary template assembly is arranged in the through hole and can rotate based ona central shaft of the rotary template assembly, and a guide hole for a puncture needle to pass through is formed in the rotary template assembly; and an axial direction of the rotary template assembly is parallel to an axial direction of the through hole. The adjustable puncture template can flexibly adjust a puncture position, adapt to puncture requirements of different angles, expand puncture range, and improve efficiency and puncture precision of minimally invasive therapies such as puncture ablation and particle implantation. The puncture template is particularly suitable for prostate biopsy or puncture therapy and tissue biopsy of other parts.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an 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 puncture nee...
