Uterine cavity cutter knife and connecting method of uterine cavity cutter knife

Abstract

The invention discloses a uterine cavity cutter knife, which solves problems of complicated structure, difficult operation, large injury, long operation time and expensive cost and the problem that the damage can be caused easily of using hard shears or semi-hard shears in the prior art. The uterine cavity cutter knife mainly consists of an operating rod (1), a handle (2) and a cutter blade (3), wherein the handle (2) is arranged at the first end part of the operating rod (1), and the cutter blade (3) is arranged at and detachably connected to the second end part of the operating rod (1), the included angle between the cutter point of the cutter blade (3) and the operating rod (1) is 45-90 degrees; and the cutter blade (3) is in detachably connected with the operating rod (1) through a card slot or / and threads. On the basis of the structure, the invention also discloses a connecting method of the uterine cavity cutter knife. The uterine cavity cutter knife is simple in structure, low in cost and easy in operation, thereby being suitable for popularization.

Description

technical field [0001] The invention relates to a surgical appliance, in particular to a uterine cavity cutting knife and a connection method thereof. Background technique [0002] Intrauterine adhesions are one of the common factors leading to infertility. At present, intrauterine adhesions often advocate the use of "cold knife" for cutting intrauterine adhesions. However, there is no real "cold knife" for uterine adhesions in the prior art. Cavity sticking, doctors generally use hard scissors or semi-hard scissors instead of "cold knife" when performing surgery. [0003] When using hard scissors, the hard scissors are usually fixed on the uterine operating mirror. Due to the large diameter of the operating mirror sheath, it is necessary to dilate the cervix to the No. 10 probe during the operation. Cervical damage is greater; while the structure of semi-hard scissors such as figure 1 As shown, it is an inner core structure, one end of the inner core is connected to the o...

AI Technical Summary

Problems solved by technology

This kind of scissors is expensive, the price of a pair of scissors is more than 10,000 yuan, and the operation is very difficult, the operation time is long, and the operator's skill requirements are very high; and this kind of semi-hard scissors is easy to damage, and only five cases can be done Left and right surgery, the scissors will be broken or broken, not only the maintenance time is long, it is inconvenient to maintain, but also the repair and maintenance costs are relatively expensive, which leads to the high cost of surgery, which brings a serious financial burden to most infertile women

[0004] On the other hand, if a pair of hard scissors or semi-hard scissors is used repeatedly, especially the scissors part responsible for the main work, because it will directly contact the tissue in the uterine cavity (adhesion), bacteria or viruses will inevitably adhere to the scissors part , although the current disinfection technology is very advanced and the disinfection effect is relatively thorough, it is impossible to change one person at a time. For patients and doctors, there are also potential safety hazards.
