Description

Technical field [0001] The invention relates to a medical article, in particular to a ring pusher. Background technique [0002] In recent years, the application of the levonorgestrel intrauterine birth control system brand name Mirena, or IUS, is relatively mature. 111 countries around the world have approved the use of this birth control system, which is mainly used for contraception, idiopathic menorrhagia, and hormone replacement therapy HRT , And treatment of gynecological diseases such as dysmenorrhea caused by adenomyosis. There are data showing that patients with dysmenorrhea and heavy menstrual flow have a higher probability of levonorgestrel intrauterine contraceptive system shifting and prolapse. On the one hand, patients with a lower birth control system have lower abdominal pain and increased menstrual flow. On the other hand, they worry about contraception failure or interruption of treatment after the birth control system breaks out. With the development of socie...

Problems solved by technology

However, the purpose of intrauterine foreign body forceps is mainly to take out IUDs or intrauterine residual bone fragments, etc., and there are 5 deficiencies in the process of pushing IUDs for such surgical instruments: 1. The toothed surfaces of this type of surgical forceps are all flat , while Mirena's hormone storage is a cylindrical structure and polyethylene material, it is easy to squeeze the hormone storage capsule when pushing, resulting in deformation or damage of the part, leakage of hormone drugs, etc.; 2. The clamp head of this type of instrument The length of the bit is 20mm, while the length of Mirena’s ring body is 32mm. The birth control system exceeds the length of the surgical instrument, and there is a risk of uterine perforation during the pushing process; 3. The flat mouth design is prone to vertical axis rotation during the pushing process; 4. Palace The cavity foreign body forceps has no lock design, and the Mirena slips halfway during the pushing process. The doctor cannot use the strength of the wrist but the strength of the arm during the operation, which is time-consuming and laborious to operate; 5. Release the ring body after pushing it in place Difficult, due to the friction between the toothed structure and the ring body, the ring body sticks to the foreign body forceps
