Intra uterine device place-in apparatus and operation method thereof

Abstract

The invention belongs to the medical apparatus, and discloses an Intra uterine device place-in apparatus comprising a handle bar formed by a bar portion and a handle portion; a side wall of the front portion of the rod portion is provided with a wire inlet; the rear end of the handle portion is provided with a wire outlet; the wire inlet is connected with the wire outlet through a fixing stay wire channel; a fork head is arranged on the front end of the handle bar, comprises two fork arms, and the front end of the fork arm is provided with a holder slot; two ends of the fixing stay wire respectively turn around two sides of the rear end of the Intra uterine device, the fixing stay wire then enters the fixing stay wire channel through the wire inlet, and exits the wire outlet; a press wire plug inserts the wire outlet so as to tighten and fix two ends of the fixing stay wire; a stay wire guide wire is used for guiding the fixing stay wire. The Intra uterine device place-in apparatus is simple in structure, low in cost, is disposable, safe and clean, convenient and fast in operation, good in applicability, and can be applied to Intra uterine devices of random shapes; the Intra uterine device place-in apparatus can adjust a direction of the Intra uterine device in the uterine cavity, so the Intra uterine device can be placed in a best position, thus ensuring birth control effect.

Description

technical field [0001] The present invention relates to a medical instrument, in particular to an implantation device which can be applied to various shapes of contraceptive devices. Background technique [0002] The IUD is a contraceptive device placed in the uterine cavity. It is placed in the uterine cavity of women of childbearing age to achieve the purpose of abortion and contraception through mechanical stimulation and chemical interference. Because it does not inhibit ovulation, it does not affect women. Endocrine system, avoiding the adverse reactions of general drug contraception, coupled with its economical and effective, easy to pick and place, and thus become one of the most commonly used contraceptive measures, especially in my country. The operation of placing the IUD in the uterus is commonly known as "upper ring", which usually requires the use of an upper ring fork, upper ring forceps or a cannula-like insertion device to complete the operation.

AI Technical Summary

Problems solved by technology

[0003] Among them, the front end of the upper ring fork is the fork head and the rear end is the handle. It is used by many doctors because of its simple structure and smooth operation. However, during the operation process, the IUD cannot be fixed. It is easy to slip off and has a low success rate; it is usually only suitable for ring-shaped IUDs, but it is not suitable for Y-shaped and M-shaped IUDs that appear later. When using the IUD, the placement direction of the IUD in the uterine cavity cannot be ensured, which will affect the effect of birth control

[0004] The upper ring forceps are hinged by two forceps arms through the rotating shaft to form a pincer shape. During operation, the forceps head is used to hold the IUD into the uterine cavity. When the upper ring forceps is moved out, it is difficult to ensure that the forceps head is completely separated from the IUD. During the process, the IUD is firmly clamped, and the two usually have a large clamping contact area. Therefore, during the removal process of the upper ring forceps, the clamp head is easy to carry the IUD and cause displacement, which makes the IUD break away from the expected correct position. Affects the placement effect of the IUD; at the same time, it has a better clamping effect for the ring-shaped IUD, but for non-ring-shaped IUDs such as M-shaped and Y-shaped, there is no better clamping position , its operating effect is not good, and it is even unsuitable; in addition, it is a slender pliers device, and the pliers head needs to be opened during the operation, which requires a large operating space and is inconvenient to use. Only metal materials can realize its structure and function, and most of them are made of stainless steel, which is not disposable and has potential safety hazards

[0005] The sleeve-shaped insertion device is usually composed of a sleeve and its internal core tube. During the operation, the IUD is gathered at the front end of the sleeve in advance. After reaching the uterine cavity, the core tube is used to push the IUD from the front end of the sleeve. Return to the normal shape to complete the insertion operation. Although it is convenient to use and does not need to expand the cervix during the operation, but because the IUD needs to be forcibly folded in the sleeve before insertion, the deformation is relatively large, with IUDs with metal components are prone to permanent deformation and cannot return to their original optimal state, thereby affecting the birth control effect; at the same time, when the IUD is released from the sleeve, it will jump under the action of elastic force, It is difficult to ensure that the IUD is in the best placement position and placement direction, which also has a considerable impact on the birth control effect
