Description

Technical Field

[0001] The invention relates to the medical field, and in particular to an automatic pessary taking and placing device for patients with uterine prolapse. Background Art

[0002] Uterine prolapse refers to the descent of the normal position of the uterus along the vagina, with the external opening of the cervix reaching below the level of the ischial spine, or even the entire uterus protruding from the vaginal opening. Its clinical manifestations include vaginal prolapse, lower abdominal distension, lumbar pain, increased vaginal discharge, and abnormal urination and defecation, which seriously affect the patient's quality of life. The disease mainly occurs in middle-aged and elderly women, and its onset is related to malnutrition or multiple births, women who do physical labor, and relaxation of the ligaments supporting the uterus or weakened pelvic floor support. Although it will not endanger the patient's life, its symptoms are severe, treatment is difficult, and the recurrence rate is high, which seriously affects the patient's quality of life. With the aggravation of the aging of the population, the incidence of uterine prolapse will also show an increasing trend year by year.

[0003] At present, treatment methods are divided into surgical treatment and conservative treatment. Although surgical treatment can achieve good results, there are many postoperative complications and there are great risks in surgery, which limits its clinical application. The main method of conservative treatment is to place a pessary in the vagina, which is a reversible conservative treatment method. Compared with surgical treatment, conservative treatment has satisfactory efficacy, can relieve the patient's pain in a short period of time, has high clinical application value, and is acceptable to patients who cannot tolerate surgery or are older. It can also be used for those who have fertility requirements and can effectively reduce the occurrence of complications. However, during conservative treatment, it is necessary to strictly follow the standardized operation methods, especially the correct placement of the pessary, in order to effectively reduce the rate of pessary shedding and the incidence of complications, and significantly improve the clinical treatment effect; and currently, the wearing and removal of the pessary is mainly done by the patient himself or with the assistance of his family. Considering that the patients with uterine prolapse are mainly elderly patients, it is difficult to operate by themselves, and most of them need to be completed with the assistance of their family members, which brings a lot of inconvenience and embarrassment. In addition, there are many problems such as infection caused by poor disinfection when removing the pessary by hand. Currently, there is no device that can assist in wearing and removing a pessary in clinical practice, so it is of great significance to design a device that focuses on helping patients wear and remove a pessary.

[0022] like Figure 1-3 As shown, an embodiment of the present invention relates to an automatic pessary removal and placement device for patients with uterine prolapse, including a shell 4, a clamp 8 and a push plate 9, wherein a screw 11 is axially arranged horizontally inside the shell 4, one end of the screw 11 is fixedly connected to a clamp frame 3, and a clamp 8 is arranged on the clamp frame 3 to extend outwardly and rotate, the push plate 9 passes through the clamp 8 and is slidably installed in the shell 4 so that the clamp frame 3 is placed inside the push plate 9, and the other end of the screw 11 is sleeved with a screw gear 14 and is connected to a motor 6.

[0023] The clips 8 are arranged in a cross shape, and the clip guide rails 7 are sleeved on the outside of the clips 8 .

[0024] A clamp limit baffle 1 is fixedly installed inside the push plate 9. One end of the clamp limit baffle 1 is open and a clamp 8 extends outward from the open end.

[0025] A clip spring 2 is connected between the clip 8 and the clip frame 3 .

[0026] The screw rod 11 is provided with a first limit baffle 10 , a second limit baffle 12 and a third limit baffle 15 in sequence along its axial direction.

[0027] The motor 6 is powered by a battery pack 16 arranged on one side thereof. A motor gear 5 is installed at the front end of the motor 6 . The motor gear 5 is meshed with a screw gear 14 . The screw gear 14 is arranged in a gear fixing seat 13 located at one end of the screw 11 .

[0028] Example

[0029] like Figure 4 , a pessary 17 (the pessary 17 is made of silicone. Silicone is soft, has no special smell, is easy to clean, etc., so that patients are not likely to feel uncomfortable after wearing it. In addition, the pessary 17 exerts little pressure on the patient's vagina and does not affect the discharge of the patient's vaginal secretions, which has great advantages). Currently, there are mainly stem-type and ring-filled types in clinical practice, with diameters including 51mm, 57mm, 64mm, 70mm, and 76mm. According to the patient's condition, a suitable model is selected and lubricant is applied to the edge of the pessary 17. The pessary 17 with the selected model and lubricant is placed on the port of the device, and the forward motor 6 is started. The screw gear 14 is driven by the motor gear 5, so that the screw 11 moves under the rotation of the screw gear 14, thereby driving the clamp frame 3 to move, and the clamp 8 quickly clamps the pessary 17 due to the clamp limit baffle 1; Figure 5 When the screw rod 11 moves, the clamp frame 3 drags the pessary 17 into the device, and at the same time drags the push plate 9 into the device. When the pessary 17 is dragged to the outer edge and only a small semicircle is left, the motor 6 automatically stops rotating in the forward direction under the action of the first limit baffle 10.

[0030] like Figure 6 , reversely start the forward motor 6, and drive the screw gear 14 through the motor gear 5, so that the screw 11 moves under the rotation of the screw gear 14, and the push plate 9 and the clamp frame 3 are pushed to move under the action of the first limit baffle 10. As the clamp frame 3 moves, the clamp 8 is quickly opened; Figure 7 As the screw 11 moves, the push plate 9 gradually pushes the pessary 17 out of the device. At the same time, the patient separates her labia by herself, presses the posterior wall of the vagina lightly with her left hand, and inserts the pessary 17 into her vagina with her right hand. After the insertion is completed, the patient completes the actions of sitting, squatting, sitting, standing, walking, urinating, etc. by herself. The patient is observed for 30 minutes. If the pessary 17 does not slip off, urinates independently, and there is no pressure or pain, the insertion is successful. The pessary 17 is inserted in the morning every day and taken out in the evening. It needs to be cleaned regularly. Similarly, when the pessary 17 is taken out of the vagina, follow the Figure 7 , Figure 6 , Figure 5 , Figure 4During use, please note that the direction and depth of the device in the vagina should be basically consistent to avoid affecting personal safety.

[0031] The second limiting baffle 12 and the third limiting baffle 15 limit the lateral movement distance of the screw 11, so that the pessary 17 is dragged inward to a position such as Figure 5 state, and push outward to Figure 7 status, while ensuring the work quality, improving work efficiency.
