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 fol...

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.

[0022] Examples:

[0023] See figure 1 with figure 2 , A catheter 1 with a catheter lumen 11 formed in the center of the length direction is given. The left end of the catheter 1 is formed with a hook head 12 for hooking the intrauterine device, and the hook head 12 is formed with a hook groove 121, An operating handle 13 is inherently sheathed at the right end of the catheter 1.

[0024] As the technical point of the technical solution provided by the present invention: the structural system of the aforementioned visual intrauterine device removal device also includes a miniature camera 2 which is arranged on the end of the aforementioned hook 12 facing away from the hook groove 121 The end surface is fixed on the left end surface of the hook 12, and the micro camera 2 is led out from the right end of the catheter cavity 11 by the micro camera transmission line 21 (also called the micro camera data transmission line) after passing through the catheter cavity 11 The video device is electrically connected, wherein: a physiological arc bending section 14 is formed at the left end of the catheter 1, and the aforementioned hook 12 is formed at the left end of the physiological arc bending section 14. The video device mentioned here refers to the image acquisition system, and the physiological curvature curved section 14 mentioned here is curved in a circular arc shape, and the degree of curvature is compatible with the physiological curvature of the female reproductive system. , Enter the uterine cavity in the state of the posterior wall, it is not easy to damage the uterine wall.

[0025] Preferably, a sleeve 15 (also called a tip) is placed on the catheter 1 and at a position corresponding to the right end of the catheter lumen 11, and the micro camera transmission line of the micro camera 2 passes through the sleeve 15 and then communicates with the aforementioned The video device is electrically connected.

[0026] Preferably, a scale mark 16 is formed on the outer wall of the aforementioned catheter 1 and in the area between the operating handle 13 and the physiological curvature section 14 for prompting the surgeon the depth of insertion of the catheter 1 into the subject, and the surgeon can According to the scale mark 16, the depth of the catheter 1 entering the uterine cavity is judged.

[0027] In this embodiment, the outer diameter of the aforementioned catheter 1 is preferably 3-10 mm, preferably 5-8 mm, more preferably 6-7 mm, and most preferably 6.5 mm. In this embodiment, 6.5 mm is selected. It can be seen that the catheter 1 is relatively slender, and this slender catheter 1 is beneficial to decompress the uterine cavity during the operation and reduce damage.

[0028] by figure 1 with figure 2 As shown, an angle is formed between the hook head 12 and the hook groove 121, that is, the hook groove 121 has an angle, and the angle is an acute angle. In the use state, both sides of the hook groove 121 can be used as focus points to increase the contact area with the IUD. After the IUD enters the hook groove 121, there will be no slippage phenomenon, which can avoid intrauterine birth control. The repeated hooking of the organ damages the uterine wall of the uterus.

[0029] Preferably, a transmission line plug 211 is connected to the right end of the aforementioned micro camera transmission line 21, which is electrically connected to the aforementioned video device; a mesh anti-slip thread 131 is formed on the outer wall of the aforementioned handle 13 by means of a mesh The non-slip thread 131 is convenient for the surgeon to hold and apply force.

[0030] Preferably, the aforementioned catheter 1 is a compliant medical plastic tube, specifically a medical grade PVC tube, and is disposable to avoid cross-infection.

[0031] In addition, by figure 1 with figure 2 As shown, the surfaces of the aforementioned hook 12 and the micro-camera 2 that are in contact with the uterus in use are very smooth, so as to avoid scratching the uterine wall during the operation of removing the intrauterine device. The aforementioned catheter 1 Especially the bending section of physiological arc is the same.
