Uterus expanding gun

Abstract

The invention discloses a uterus expanding gun. The uterus expanding gun comprises a gun tube and a gun handle. The front end of the gun tube is provided with a rugby-shaped expanding ball, the expanding ball is enclosed by a plurality of strip pieces, the front ends of the strip pieces are fixed to a push-pull ring, the gun tube is internally provided with a push-pull tube, the front end of the push-pull tube is fixed to the push-pull ring, and the rear portion of the push-pull tube is in threaded connection with a manual adjustment nut. The expanding ball with diameter variable is adopted for replacing many sizes of expanding rods used in traditional operations, the rods do not need to be changed frequently during the operations, the operation time is saved, and the disadvantages of a friction tissue surface caused by replacement of the rods are reduced. The expanding ball is gradually enlarged according to set gears, so that the phenomenon of manually taking the wrong rods in traditional operations is avoided. At the same time, the gun tube and the expanding ball are heated so that ice tingling feeling brought by stainless steel expanding rods to people can be avoided. The uterus expanding gun has both a manual mode and an electric mode and is easy and convenient to operate, the operation efficiency is greatly improved, and meanwhile a comfortable experience is brought to surgery accepters.

Description

technical field [0001] The invention relates to a medical device, in particular to a uterine expansion gun. Background technique [0002] As a gynecological medical device, the uterine dilator is widely used in dilating the cervix in uterine surgery in obstetrics and gynecology. A set of uterine expansion sticks to be used in a complete uterine dilation process is usually 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc., the number is large, and it needs to be used from small to small during the operation. Changing from one size to another size will not only waste the operation time, but also increase the pain of the patient and cause damage to the cervix. There are too many types of dilating sticks in use, and it is easy to use the wrong ones during the operation. It not only delays the operation, but also brings harm to the recipient. In addition, most of the uterine expansion rods used in current operations are made of stainless steel, which is very cold, and directl...

A set of uterine expansion sticks to be used in a complete uterine dilation process is usually 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc., the number is large, and it needs to be used from small to small during the operation. Changing from one size to another size will not only waste the operation time, but also increase the pain of the patient and cause damage to the cervix. There are too many types of dilating sticks in use, and it is easy to use the wrong ones during the operation. It not only delays the operation, but also brings harm to the patients; in addition, most of the uterine expansion rods used in current operations are made of stainless steel, which is very cold, and directly used in internal operations will cause adverse stimulation to human organs

In order to solve the trouble of frequent replacement of uterine dilation rods, save operation time, and bring comfortable experience to the patients, a simple and easy-to-use uterine dilation device is urgently needed.
