A tissue resection system and method for determining cutting parameters thereof

Abstract

The present invention provides a tissue resection system and a method for determining cutting parameters, comprising the following steps: acquiring a three-dimensional ultrasonic image of a target tissue; slicing the three-dimensional ultrasonic image according to a preset step length to obtain a plurality of two-dimensional slice images; determining Target tissue contour information and ablation tool contour information in the two-dimensional slice image; determining cutting parameters based on the determined target tissue contour information and ablation tool contour information, the cutting parameters at least include: cutting position parameters (L), One of the cutting depth parameter (R) and cutting angle parameter (β). The present invention can calculate cutting parameters more efficiently, and can more accurately plan a more reasonable and larger cutting range, taking into account cutting efficiency, cutting area and safety.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a tissue cutting system and a method for determining cutting parameters thereof. Background technique [0002] Benign prostatic hyperplasia (BPH), also known as benign prostatic hyperplasia, is located in the bladder neck, obstructing the urinary tract, causing frequent urination and dysuria, and seriously affecting the quality of life of patients. It is a common disease of middle-aged and elderly men, also known as benign Prostatic hypertrophy ranks second only to urolithiasis among inpatients in urology. For hyperplastic tissue or cancer tissue, in addition to drug treatment, traditional surgical resection or partial resection has been commonly used for a long time. This method generally relies on open incisions, and has the disadvantages of strong invasiveness, large trauma, and long recovery period. . Post-minimally invasive excision therapy has been widely used in this fie...

Problems solved by technology

The defect of this method is obvious. Due to the dependence on the participation of doctors, on the one hand, in view of the objective influence of image quality and manual operation errors, there is a lot of uncertainty in the determination of cutting parameters. When the doctor has less experience, the plan will be difficult to carry out. Or it is difficult to obtain the expected resection effect, or lead to the occurrence of undesired surgical accidents. On the other hand, manual indexing increases the workload of medical staff, cumbersome operations also make the surgical process lengthy, and the patient’s surgical experience deteriorates. More rejection or rejection of such surgery, delaying treatment
