Myomectomy Device

Abstract

The invention discloses a device for removing a myoma, and the device is to solve the problem that the existing myoma-removing device is difficult to precision operation due to a heavy front end. The device for removing myoma comprises a transmission component connected with a power source and arranged in a base, an inner pipe combined with the transmission component and passed through the base, and an outer pipe sleeved in the inner pipe, wherein one end of the inner pipe is provided with a cutting part while the other end thereof is provided with a clearance hole; the inner pipe is configured with a guide groove on an internal periclinal wall between the cutting part and the clearance hole; one end of the outer pipe is connected with the base by a flexible control component and the displacement of the outer pipe versus the inner pipe is controlled.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a myomectomy device for removing myoma. Background technique [0002] Nodules are often formed when muscle cells or connective tissue cells in human organs proliferate abnormally. After a period of development and growth, nodules often become larger fibroids, which in turn affect the normal function of the organ or surrounding organs ; For example, the clinically more common fibroids are uterine fibroids (Myoma), and because uterine fibroids are the most common type of tumors in women, hysterectomy has been performed in the world including Taiwan. It is listed as the most common obstetrics and gynecology operation except caesarean section, and the main reason for hysterectomy is uterine fibroids. [0003] Please refer to figure 1 , is the myomectomy device 9 disclosed in the patent case of China Taiwan Publication No. 201223495 "Surgical Resection Device". This existing myomectomy devic...

Problems solved by technology

[0005] However, because the existing myomectomy device 9 is provided with the guide rod 93, the weight of the front end of the myomectomy device 9 (that is, the "part penetrating into the patient's body") is increased, thereby affecting the myomectomy The operational flexibility of the device 9 makes the myomectomy device 9 have the disadvantage of being difficult to precisely control

In addition, the existing myomectomy device 9 is blocked by the guide rod 93, so that the inside of the outer tube 92 is difficult to clean; in operation, the lock ring 921 needs to be loosened, and the outer tube 92 and The guide rod 93 is disassembled and separated from the base 91, and the cleaning work can be carried out separately

[0006] Furthermore, because the cutting portion 931 directly exposes and protrudes from one end of the outer tube 92 to cut the fibroid, the exposed cutting portion 931 will be easy to cut when the outer tube 92 is inserted into the patient's body. Delimited to the position other than the affected part, making the use safety of this existing myomectomy device 9 questionable
