Myoma rotary-cutting extractor

Abstract

The invention discloses a myoma rotary-cutting extractor. The myoma rotary-cutting extractor comprises a myoma rotary-sending device and a myoma turning-cutting device, wherein the myoma rotary-sending device comprises a handle I, a rotary-sending cutter and a rear seat; the handle I is located at one end of the rear seat, and is fixedly connected with the rear seat, a gear decelerating thrust boosting mechanism I and an electric motor I are arranged in the rear seat, and the gear decelerating thrust boosting mechanism I is connected with the rotary-sending cutter and the electric motor I; anopening is formed in the side surface of the rear seat, and is a discharging opening; the myoma turning-cutting device comprises a handle II, a turning cylinder and a cylinder seat, wherein the handleII is fixedly connected with the cylinder seat, the turning cylinder sleeves the inner surface of the cylinder seat, an electric motor II is arranged in the handle II, and a gear decelerating thrustboosting mechanism II is arranged in the cylinder seat and is connected with the turning cylinder and the electric motor II; and a zigzag edge opening and tooth sharpening structure is arranged at oneend of the turning cylinder. Compared with a conventional myoma drill, the myoma rotary-cutting extractor disclosed by the invention has obvious advantages, and the myoma rotary-cutting extractor hasthe advantages of being simple to operate, high in efficiency, high in safety, broad in application range and the like, and is broad in application prospects.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for removing hysteromyoma by rotary cutting. Background technique [0002] Uterine fibroids are the most common benign tumors of the female reproductive system, accounting for about 1 / 5 of women of childbearing age. The surgical treatment methods include simple uterine fibroid excavation or total hysterectomy. With the improvement of people's requirements for minimally invasive surgery, laparoscopy is more and more widely used in uterine fibroid surgery, because the laparoscopic minimally invasive abdominal incision is as small as 1cm, but it makes it difficult to remove the fibroids. At present, fibroids are commonly used to drill fibroids in clinical practice. This device is only suitable for use in areas with large spaces such as the pelvis and abdomen. When using it, it is necessary to fix the fibroids with clamps, and then cut the fibroids. The f...

With the improvement of people's requirements for minimally invasive surgery, laparoscopy is more and more widely used in uterine fibroid surgery, because the laparoscopic minimally invasive abdominal incision is as small as 1cm, but it makes it difficult to remove the fibroids

At present, fibroids are commonly used to drill fibroids in clinical practice. This device is only suitable for use in areas with large spaces such as the pelvis and abdomen. When using it, it is necessary to fix the fibroids with clamps, and then cut the fibroids. The clamps are not secure and easy to slip. Due to the design defect of the device, the cut fibroid tissue is likely to be broken, and the cut tissue cannot be taken out this time.

In addition, if the fibroids are potentially malignant, taking the fibroids with this device can easily cause iatrogenic tumor dissemination and planting

Therefore, for fibroids that are suspected of being malignant, they are often put into a pick-up bag after surgical stripping, and the mouth of the pick-up bag is lifted out of the abdominal cavity through the incision of the abdominal wall. Due to the narrow space in the pick-up bag, traditional myoma drills cannot complete the removal of fibroids. Clamping and cutting. At present, only manual clamping and scalpel cutting methods can be used to remove fibroids. There are difficulties in clamping. Only broken fibroids the size of corn kernels can be removed each time. The time taken for fibroids often occupies the entire operation. and more than half of the anesthesia time, so the efficiency is extremely low, which not only wastes time, consumes physical strength, makes the operator physically and mentally exhausted, but also increases the anesthesia cost and risk of the patient
