Ablation tool array device for tissue resection and control method thereof

Abstract

The invention provides an ablation tool array device for tissue resection and a control method thereof. The ablation tool array device comprises a plurality of ablation tool modules controlled by a control unit; each ablation tool module comprises a driving motor, a tool driving part and an ablation tool controlled by the control unit, and an energy emitting port is formed in the front end of each ablation tool; the driving motor controls the corresponding ablation tool to move through the corresponding tool driving part; and the ablation tools of the plurality of ablation tool modules can move independently and can work simultaneously. The ablation tool array device has the advantages of being high in cutting efficiency, high in cutting precision, simple in structure, easy and convenient to operate, thorough in focus excision, high in safety and the like.

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
