Uterine fibroids or uterine corpus rotary cutting morcellator

Abstract

The invention provides a uterine fibroid or uterine body rotary cutting grinder and aims to provide a uterine fibroid grinder which can prevent damage of a grinding bag and is simple and convenient to operate. The uterine fibroid or uterine body rotary cutting grinder comprises a circular tube rotary cutting grinding cutter matched with a sheath; the sheath comprises a sheath body (4) in the shape of a funnel, a thread insert (2) fixed at the upper end opening of the sheath body, an upper sealing cap (1) fixed at the top end of the thread insert, and a lower air cap (3) fixed at the bottom end of the thread insert. The rotary cutting grinding cutter comprises a cutter tube (8) provided with a cutting edge at the front end tube opening, and a cutter tube base (10) fixed on the cutter tube. At least one valve (9) is fixed to the sheath body (4). The lower end opening (5) of the sheath body is n inclined groove or an inward-bending curved groove. The front end tube opening of the cutter tube (8) is located between the lowest portion and the highest portion of the lower end opening. The uterine fibroid or uterine body rotary cutting grinder is simple in structure, convenient to operate and high in safety, and is used for rotary cutting and grinding of uterine fibroid in laparoscopic minimally invasive operations.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a uterine fibroid or uterine corpuscle rotary cutter, which belongs to medical instruments. Background technique [0002] As we all know, laparoscopic subtotal hysterectomy or myomectomy has been popularized and used clinically for many years due to its advantages of small opening and fast recovery; Whole uterus. The hysteromyoma pulverizer usually consists of a funnel-shaped scabbard and a circular tube-shaped rotary cutting pulverizer located in the scabbard. Driven by the motor, the rotary cutting comminutor can remove the fibroids from the body, avoiding the long surgical incision caused by traditional laparotomy. However, during the operation, the fibroids are performed under unprotected conditions (that is, the rotary knife is performed under the condition that the fibroid specimens are completely exposed to the abdominal cavity), and the detachment of fibroid cells, cell clusters...

AI Technical Summary

Problems solved by technology

[0005] However, when using a conventional uterine fibroid pulverizer for surgery, since the length of the knife tube is greater than the length of the scabbard, the cutting edge of the knife tube will protrude from the lower port of the sheath body; Fibroid cells, cell clusters or tissue fragments leak and scatter in the abdominal cavity by breaking the crushed bag, causing contamination; there are defects such as difficult operation and high risk of contamination

In addition, the sheath of the uterine fibroid pulverizer of the traditional structure is not provided with an air inlet and an exhaust port, and the rotary cutting pulverizer must be taken out of the scabbard before it can be inflated into the pulverizing bag through the upper port of the scabbard; not only The operation is cumbersome, and it is impossible to supply or exhaust air into the crushing bag during the fibroid crushing process
