A contraceptive device insertion device and its operating method

Abstract

The invention belongs to a medical device, and discloses a device for inserting a birth control device, which includes a handle rod composed of a rod part and a handle part. The front side wall of the rod part is provided with a wire inlet hole, and the rear end of the handle part is provided with a wire outlet hole. The wire inlet hole and the wire outlet hole are connected through the fixed cable channel; the fork is installed on the front end of the handle rod, which has two fork arms, and the front end of the fork arm is provided with brackets; The two sides of the cable are bypassed, and then penetrate the fixed cable channel through the cable inlet hole, and lead out from the cable outlet hole; the crimping plug is inserted into the cable outlet hole, and the two ends of the fixed cable are pressed and fixed; the cable guide wire is used to guide the fixed cable. The structure is simple, the cost is low, and it is suitable for one-time use, safe and hygienic, and the operation is convenient and fast; it has good applicability and can be used for any shape of the birth control device; it is convenient to adjust the direction of the birth control device in the uterine cavity, and can be stably placed in the most Optimum position, thus ensuring the birth control effect.

Description

technical field [0001] The invention relates to a medical device, in particular to an insertion device applicable to birth control devices of various shapes. 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 interference of chemical substances. Since it does not inhibit ovulation, it does not affect women. The endocrine system avoids the adverse reactions of general drug contraception, and it is economical and effective, and the operation is easy to take and put, so it has become one of the most commonly used contraceptive measures, especially in my country. The operation of inserting the IUD into the uterus is commonly known as "upper ring", which usually requires the help of upper ring fork, upper ring forceps or sleeve-shaped insertion device to complete the operation.

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
