An ablation tool array device for tissue resection and its control method

Abstract

The present invention provides an ablation tool array device for tissue resection and a control method thereof, comprising a plurality of ablation tool modules respectively controlled by a control unit, the ablation tool modules including a driving motor and a tool driving component controlled by the control unit and an ablation tool, the front end of the ablation tool is provided with an energy output port; the drive motor controls the movement of the ablation tool through the tool driving component; the ablation tools of the plurality of ablation tool modules can move independently of each other and can be performed simultaneously Work. The ablation tool array device of the present invention has beneficial effects such as high cutting efficiency, high cutting precision, simple structure, easy operation, thorough lesion excision, and high safety.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an ablation tool array device for tissue resection and a control method thereof. Background technique [0002] For the treatment of proliferative tissue or cancer tissue, such as benign prostatic hyperplasia (BPH), prostate cancer, etc., in addition to drug therapy, traditional surgical resection or partial resection has been commonly used for a long time, which generally relies on open incisions , has the disadvantages of strong invasiveness, large trauma, and long recovery period. Post-minimally invasive resection therapy is widely used in this field, such as using energy such as laser, water jet, and optical fiber as fluid flow to resect and / or cauterize lesions or hyperplastic tissues on tissues such as the prostate, which generally enters through the urethra without The open incision has the advantage of less trauma. [0003] The prior art prostatectomy device includes a p...

AI Technical Summary

Problems solved by technology

However, the above-mentioned prior art is a single ablation tool system. Since the shape of hyperplasia and tumor tissue is usually irregular, after the above-mentioned resection equipment enters the human body, its cutting range is limited. Constantly adjust the nozzle / orifice angle, cutting depth, energy intensity and other working parameters in stages, resulting in low cutting efficiency, prolonged operation time, and poor patient experience

At the same time, there is also the problem of tissue collapse after partial tissue resection, which has an adverse effect on the resection of other tissues to be cut, which may lead to incomplete resection

As an improved existing technology, there are also multi-nozzle structural designs. Although this type of technical solution can improve cutting efficiency to a certain extent, it still has the following defects: the operator cannot individually control the cutting parameters of one of the nozzles, and cannot Separately control the position and movement of a single nozzle. When cutting irregular tissues such as hyperplastic tissue or tumor tissue, not only the cutting accuracy is poor, but also the safety is problematic.

More seriously, when it is used for BPH resection, it is very easy to touch sensitive parts such as the spermary caruncle, and the wrong removal of this part will cause serious damage to the health of the patient
