Uterine Inversion correcting and resetting machine

Abstract

The invention discloses a uterine inversion correcting and resetting machine. The uterine inversion correcting and resetting machine comprises a silica gel guide barrel, a piston head and a push rod; the silica gel guide barrel is provided with a skeleton support with a straight barrel type structure, an inner cavity of the skeleton support is provided with a plurality of linkage supporting plates, the bottoms of the linkage supporting plates are in sliding connection with the surface of the inner cavity of the skeleton support through linkage supporting plate guide grooves formed in the skeleton support in the axial direction; the outer surface of the skeleton support is coated with a silica gel guide barrel silica gel layer, the upper end of the silica gel guide barrel silica gel layer adopts a flared structure which is internally provided with tractive positioning points and extends outwards, and the tractive positioning points are connected with the bottom ends of the linkage supporting plates through steel wires; and the piston head is arranged in the barrel-shaped inner cavity of the skeleton support and positioned above the linkage supporting plates. The uterine inversion correcting and resetting machine is convenient to operate, and can prevent endometrium from being folded excessively and reduce the infection probability on the premise of successfully pushing the inversed uterus tissue into an abdominal cavity, thereby being particularly suitable for uterine inversion operation in case that the placenta is positioned near the bottom of the uterus.

Description

technical field [0001] The invention relates to a medical correction and reset device, in particular to a uterine inversion correction and reset device, which belongs to the technical field of medical devices. Background technique [0002] Uterine inversion refers to the lesion in which the bottom of the uterus sinks into the uterine cavity, or even turns out from the cervix. This is a rare and serious complication during childbirth. Most of them occur in the third stage of labor. Hemorrhage leads to maternal death within 3 to 4 hours. Timely detection and diagnosis of uterine inversion is the basis of treatment. Patients with uterine inversion often have clinical manifestations such as severe pain, bleeding, infection, and shock during the diagnosis and treatment process. Therefore, Active pain relief, control of bleeding, infection, and shock are the prerequisites for the treatment of uterine inversion. [0003] Factors leading to uterine inversion, in addition to materna...

Problems solved by technology

[0005] Among them, in the uterine preservation treatment measures, the uterine reset is usually when the cervical ring is not tight, there is no severe bleeding, shock infection, and the bottom of the uterine tissue that has been everted to the outside of the birth canal can be immediately held by the palm of the hand and retracted. When the reduction is difficult to expand by hand, it usually needs to be performed under anesthesia. The surgeon usually needs to rely on medical image guidance, tactile sensation and clinical experience for this manual reduction method. On the one hand, the surgical operation needs to be performed gently in a small space , Higher skill requirements for physicians. On the other hand, in the process of uterine reduction, the uterine tissue that has been everted to the outside of the birth canal is usually pushed into the birth canal with the palm of the hand, and then pushed into the abdominal cavity with a fist Internal, but not only is it prone to infection during the push-in process, but also the forearm with larger peripheral size increases the pain of the puerpera during the process of extending the arm into the abdominal cavity. Move inside to ensure the complete reset of the inner wall of the uterus, especially before it is pushed to the cervix, it is easy to cause the inner wall of the uterus to fold too much, so that the inner wall of the uterus and the inner wall of the birth canal will rub against the inner wall of the uterus, causing damage to the inner wall of the uterus, which will further increase the chance of infection
