Prostate coagulated tissue digging tool for prostate digging operation

Abstract

According to the technical scheme, a prostate coagulated tissue digging tool for the prostate digging operation is provided with an insulating hollow catheter capable of penetrating into the prostate through the urethra, a rotary knife tube capable of rotating is installed at the front end of the catheter, a knife hole is formed in the rotary knife tube, and a needle-knife mechanism capable of stretching out and drawing back along the knife hole is arranged in the rotary knife tube. A power shaft capable of moving and rotating along the catheter is arranged along the hollow catheter, the needle-knife mechanism is controlled by the front end of the power shaft to enable a needle-knife to extend out of a knife hole of the rotary knife tube, and meanwhile, the front end of the power shaft is in transmission fit with the rotary knife tube to rotate to drive the extending needle-knife to quickly cut off coagulated and necrotic prostate tissue. The tool has the beneficial effects that equipment operation is realized in the prostate digging operation, so that the accuracy of the digging operation is improved, the operation difficulty is reduced, the operation time is shortened, the digging operation becomes simple, and the operation risk and the operation cost of the prostatic hyperplasia digging operation are reduced.

Description

technical field [0001] The invention belongs to the technical field of surgical equipment, and in particular relates to a prostatic coagulated tissue excavation tool used in prostatic excavation surgery. Background technique [0002] Prostatic hyperplasia is a relatively common disease among middle-aged and elderly men. The harm is that the hyperplastic gland is located in the bladder neck, which will narrow the urinary tract and in severe cases make the urinary tract obstructed, resulting in frequent urination and dysuria for patients. For patients with severe benign prostatic hyperplasia who are unable to urinate normally, the existing relatively common treatment method is transurethral resection of the prostate. Transurethral resection of the prostate is a minimally invasive surgery that requires general anesthesia for the patient. The prostatic resectoscope is inserted from the urethra to excavate the blockage of the prostate. However, the thickness of the excavation can...
