Hysteromyoma rotary cutter

Abstract

The present invention discloses a hysteromyoma rotary cutter. The hysteromyoma rotary cutter comprises an electric device, a drilling cylinder, a connecting cylinder, a bottom plate, a connecting plate, a covering device and a push rod. The connecting cylinder sleeves outside the drilling cylinder; the connecting cylinder is a double-layer cylinder and comprises an inner cylinder and an outer cylinder, and two ends of the outer cylinder are connected with side walls of two ends of the inner cylinder to form a cavity; the bottom plate is positioned right under a cutting end of the drilling cylinder at intervals; one end of the connecting plate is connected with one side of the connecting cylinder, and the other end of the connecting plate is connected with an edge of the bottom plate; the covering device comprises a push plate, a cover body and support rods, the cover body is an inverted cone-shaped body, the support rods are uniformly arranged along the outer cylinder at intervals, oneend of each support rod is connected with a top end of the cover body, the other end of each support rod is connected to the push plate, and when the push plate moves towards a direction close to thebottom plate, the support rods can be driven to be dispersed outwards to open the cover body; and a tail end of the push rod is connected to the push plate and the other end of the push rod extends out of the connecting cylinder. The hysteromyoma rotary cutter can prevent fragments from scattering in a pelvic cavity in a hysteromyoma cutting process and avoids occurrence of planting cancer.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a rotary cutter for uterine fibroids. Background technique [0002] With the development of modern medicine, laparoscopic surgery has the advantages of less trauma and faster recovery, and has been widely used in gynecological clinics. Laparoscopic myomectomy is to open a hole of 1-5 cm on the abdominal wall, through which the instrument enters the abdominal cavity, and under the action of the laparoscope, the uterine fibroids are separated from the endometrium and the fibroids are removed through this hole. take out. However, when the diameter of the fibroid is relatively large (more than 5 cm), the entire uterine fibroid cannot be removed through the hole in the abdominal wall. The existing solution is the use of hysteromyoma rotary excision, that is, the uterine fibroids are cut into strips through a rotating drill cylinder, and the strip-shaped slices are discharged through the dri...

AI Technical Summary

Problems solved by technology

However, for some uterine fibroids, it is difficult to determine whether they are benign fibroids before the operation. This kind of laparoscopic myomectomy may easily cause uterine fibroid fragments to scatter in the abdominal and pelvic cavity during the cutting process, which may cause implantation and spread
