Suction catheter for hysteromyomectomy

Abstract

The invention discloses a suction catheter for hysteromyomectomy. The suction catheter is characterized in that the cavity of a guiding part communicates with that of an excision part, a catheter is connected to the end of the guiding part, a negative pressure machine is connected to the end of the catheter, the excision part is provided with a spherical cavity, an infrared sensor is arranged on the inner layer of the excision part , and the infrared sensor is connected to a microprocessor; the inner layer of the excision part is a diameter-adjustable cavity wall composed of snake bones, all snake bones are arranged longitudinally and formed the spherical cavity, an adjusting line is arranged at the end of each of the snake bones, a knife edge is formed by the bottom surface of a posteriorsegment of each of the snake bones, a rotating ring knife is arranged at the lower part of the posterior segment of each of the snake bones, and the rotating ring knifes and the bottom surfaces of the posterior segments of the snake bones form a cutting surface. According to the present invention, with the suction catheter, the problem that doctors use scalpels or scissors to remove tissue incompletely is solved, the recurrence of hyperplasia caused by remaining myoma is avoided, resected myoma is directly discharged from an affected area by using the guiding part, the catheter and the negative pressure machine, and myoma slipping to other organs due to untimely treatment after removal is avoided.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a suction catheter for hysteromyomectomy. Background technique [0002] Uterine fibroids are the most common benign tumors in female reproductive organs and one of the most common tumors in the human body. They are also called fibroids and uterine fibroids; , in which a small amount of fibrous connective tissue exists as a supporting tissue, it is also called uterine leiomyoma. [0003] For the treatment of uterine fibroids, follow-up observation, drug therapy and surgical treatment are commonly used in the prior art. Among them, surgical treatment has the fastest effect, and most patients can recover only through myomectomy and healthy post-treatment , Myomectomy can help patients preserve the uterus. Myomectomy usually removes myoma through the abdomen, and usually uses a scalpel or surgical scissors to remove it; however, using a scalpel or surgical scissors often cannot compl...

AI Technical Summary

Problems solved by technology

Myomectomy usually removes myoma through the abdomen, and usually uses a scalpel or surgical scissors to remove it; however, using a scalpel or surgical scissors often cannot completely remove the myoma, and may even damage normal smooth muscle; because during the operation, the myoma It is mostly a small piece of polyp, but when the doctor uses a scalpel or surgical scissors, the scalpel or surgical scissors cannot be completely perpendicular to the polyp root. After the first removal, fibroids often leave some remaining fibroids that cannot be removed due to oblique cutting or oblique cutting, and the remaining part of fibroids is often difficult to resect, and can only be removed by Drug treatment; if the patient does not recover well, it will easily cause recurrence and hyperplasia, which will increase the patient's pain and economic expenditure
