Visible multi-functional intrauterine contraceptive ring extracting method and contraceptive ring extractor

Abstract

The invention discloses a visible multi-functional intrauterine contraceptive ring extracting method, comprising the following steps of stretching a contraceptive ring extractor body into the uterus, and injecting normal saline into a one-way valve of a uterus swelling instrument to swell a balloon; observing the intrauterine condition through an endoscope, and finding an intrauterine device or a foreign matter; clamping the target object through a clamping instrument. The invention also discloses a visible multi-functional intrauterine contraceptive ring extractor which comprises the uterus swelling instrument, the endoscope and the clamping instrument, wherein the clamping component of the clamping instrument and the uterus component of the uterus swelling instrument are both arranged on the endoscope. The uterine cavity is enlarged through the uterus swelling instrument, the storage condition of a contraceptive ring in the uterus is observed through the endoscope, the intrauterine device is extracted or the foreign object is cleaned by the clamping instrument, operation can be carried out under the visible condition, the operation time is greatly shortened, the pain of a patient is relieved, the dependence on doctor technology is reduced, the accuracy and success rat of operation can be improved, and in addition, the uterus swelling instrument is a disposable accessory so as to prevent cross infection.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a visible and multifunctional intrauterine ring removal method and a ring removal device. Background technique [0002] The intrauterine device is a contraceptive device placed in the uterine cavity. Because most of the devices used in the early stage are ring-shaped, they are usually called birth control rings. The birth control ring has less interference to the whole body, acts on the local area, and does not affect fertility after being taken out. It has the advantages of safety, effectiveness, reversibility, simplicity, and economy. It is one of the most commonly used birth control devices. An IUD is usually placed in a woman's uterus to prevent pregnancy. Birth control rings come in various shapes, including circular rings, T-shaped rings, and triangular rings. The positions and shapes of birth control rings in the uterine cavity are different, and the placement time is also ...

Problems solved by technology

Birth control rings come in various shapes, including circular rings, T-shaped rings, and triangular rings. The positions and shapes of birth control rings in the uterine cavity are different, and the placement time is also different. The long ones can reach 20 to 30 years, and the short ones Only 3 to 5 years, or less; some birth control rings are incarcerated in the uterine cavity, and it is very difficult to remove

[0003] The existing devices and devices for extracting the IUD basically include two types: one is the blind extraction of the IUD, and the blind extraction of the IUD The hook is made of stainless steel wire with a diameter of 3 mm. The diameter of the steel wire at the head is 1.3 mm. Some hooks have a radius of about 1.8 mm. , in the process of removing the contraceptive ring, it is difficult to find the contraceptive ring, the operation time is long, it is easy to damage the normal tissue, and even cause uterine perforation, it is difficult to remove the contraceptive ring with serious incarceration, and other methods or even surgery are required. pain to the patient

The other is a device for visually removing the birth control ring. Although it is operated under visible conditions, the design of the ring removal hook on the head of the sheath of the multifunctional intrauterine ring removal device with visibility is defective. The head end of the endoscope is formed by the mirror sheath body. The main disadvantage is that the ring-taking hook is too close to the head and away from the field of view of the endoscope. The ring-taking hook cannot be seen at all by the endoscope. The relative position of the ring hook and the birth control ring cannot be found, so that the operation of visually removing the birth control ring cannot be realized

Another shortcoming of this visible device for extracting the birth control ring is that the head of the ring hook and the outer diameter of the mirror sheath are at the same height, so it is difficult to hook the birth control ring during the operation, which is very inconvenient to operate and difficult to ensure the safety of the operation and effectiveness, it is easy to damage normal tissues and cause surgical accidents
