Visible intrauterine device extracting instrument

Abstract

The invention relates to a visible intrauterine device extracting instrument, and belongs to the technical field of medical instruments. The visible intrauterine device extracting instrument comprises a catheter which is provided with a catheter cavity formed in the center in the length direction. A hook head is formed at the left end of the catheter. A hook groove is formed by the hook head. The right end of the catheter is fixedly sleeved with an operating handle. The visible intrauterine device extracting instrument is characterized by further comprising a micro camera. The micro camera is arranged on the end face of one end, with the back facing the hook groove, of the hook head. After passing through the catheter cavity and being extracted from the right end of the catheter cavity, the micro camera is electrically connected with a video device through a micro camera transmission line. A physiological curvature bending section is formed at the left end of the catheter. The hook head is formed at the left end of the physiological curvature bending section. An intrauterine device can be extracted from the body of an accepter in a visible state, the blind operation can be avoided, the accurateness of an operation is guaranteed, and the difficulty of the operation is lowered; the operation time is shortened, and the operation efficiency is improved; the pain inflicted on the accepter is alleviated, and wounds dealt to the accepter and complications are reduced; the comfort feeling of the accepter is enhanced; the structure is succinct, manufacturing is convenient, and the cost paid by the accepter is lowered.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a visual intrauterine device removal device. Background technique [0002] The intrauterine device is customarily called the contraceptive ring (hereinafter the same), and it is the contraceptive tool mainly chosen by women of childbearing age in my country with the characteristics of safety, effectiveness, economy, simplicity and reversibility. However, women who use the intrauterine device sometimes suffer from The IUD needs to be removed or replaced due to circumstances such as IUD ectopia, shedding, endometrial injury, infection and bleeding, ectopic pregnancy (pregnancy with a device), menopause, complications or side effects. Therefore, IUD removal Surgery is a relatively common operation in family planning. [0003] Taking out the intrauterine device with the ring hook has the advantages of short operation time, high efficiency, low equipment cost, and ...

AI Technical Summary

Problems solved by technology

Although the removal operation under the guidance of B-ultrasound, hysteroscopy or similar equipment can avoid blindness to a certain extent, it is not conducive to saving precious medical resources and the operation time is long because of the expensive equipment. The medical expenses paid by the recipient are high, and on the other hand, it is easy to aggravate the suffering of the recipient and even cause other complications

[0004] In the published Chinese patent literature, it can be seen that all the technical information about the IUD pick-and-place device, such as CN203634355U recommends "a device for taking out the IUD", although this patent scheme can reflect its specification No. The technical effect recorded in paragraph 0009, but because it does not have a visual function, it is not conducive to reducing the difficulty of IUD removal surgery, not enough to ensure the accuracy of the operation and reduce the pain of the recipient

[0005] A typical example is the "Visible Multifunctional IUD Placement and Take-Out Device" provided by the authorized announcement number CN2805723Y. The internal contraceptive device has both, so there are the following shortcomings: one, because the overall structure is complex, so the manufacturing and use costs are higher; The clamping and fixed end on the upper part is matched with the structure, so it is operable to implant the IUD into the uterine cavity, but it is difficult to take out the IUD, because it needs to be clamped by clamping the movable end and clamping The reliable cooperation of the fixed end can clamp and take out the IUD with a pliers-like effect, and there is a risk of the IUD breaking away from the clamping movable end and clamping the fixed end during the removal process. It can be operated again, which not only affects the operation efficiency, but also increases the pain of the recipient; thirdly, because women's reproductive organs have a specific physiological curvature, the patent adopts a straight structure (when clamping the movable end and clamping When the fixed ends are closed to each other, they are in the same straight line as the clip body and the main tube), so the operation effect will be affected because the operation cannot follow the aforementioned physiological arc, and it will also aggravate the pain of the patient
