Lithotomy position operating bed

Abstract

Two front wheels and two universal trundles are installed on the lower side of a chassis, the chassis, an upper connecting plate, a lower connecting plate and a triangular frame form a parallelogram structure, the height and pitching angle of the operating bed can be adjusted, the inclination angle of a backrest can also be adjusted, armrests or bandages can be installed on the two sides of a backrest plate according to needs, and the operating bed is convenient to use. The backrest cushion and the backrest plate form a moving pair through the bottom plate, the seat cushion is installed on the seat plate, the backrest cushion does not interfere with the seat cushion when the angle of the backrest changes, the two supporting leg mechanisms are installed on the two sides of the seat plate, the seat cushion and the backrest cushion are both made of soft silica gel materials, a cavity structure in the seat cushion and the backrest cushion is filled with paraffin materials, and a heat exchange pipe is further arranged in the cavity structure. A heating device and a cooling device are integrated in the variable-temperature bin, the variable-temperature bin is communicated with the heat exchange pipes in the cushion and the backrest cushion through four pipelines respectively, and the variable-temperature bin takes a refrigerant as a heat transfer substance to enable paraffin in the cushion and the backrest cushion to be converted between a solid state and a liquid state.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a lithotomy position operating bed. Background technique [0002] The lithotomy position is a commonly used position in general surgery, gynecology, urology and other departments. It is characterized by the patient lying on his back, moving his buttocks to the bedside, and placing his legs on the leg rest. In uterine surgery, rectal surgery, urological surgery, cystoscopy surgery, etc.; surgical patients under anesthesia, due to partial or complete loss of consciousness, muscle relaxation and weakness, weakened or lost protective reflexes, have basically lost their normal adjustment This position is also the surgical position that is likely to cause complications, and it is the most likely to cause injury clinically and bring unnecessary pain to the patient; when the lithotomy position is used, the pressure parts of the patient's body are in the sacrum, shoulders, spine and oth...

Problems solved by technology

[0002] The lithotomy position is a commonly used position in general surgery, gynecology, urology and other departments. It is characterized by the patient lying on his back, moving his buttocks to the bedside, and placing his legs on the leg rest. In uterine surgery, rectal surgery, urological surgery, cystoscopy surgery, etc.; surgical patients under anesthesia, due to partial or complete loss of consciousness, muscle relaxation and weakness, weakened or lost protective reflexes, have basically lost their normal adjustment This position is also the surgical position that is likely to cause complications, and it is the most likely to cause injury clinically and bring unnecessary pain to the patient; when the lithotomy position is used, the pressure parts of the patient's body are in the sacrum, shoulders, spine and other parts , are all places where the bone prominence and the muscle and fat are thin. During the long-term operation, due to the extrusion of the patient's own body weight and the conduction of the force applied during the operation, the microcirculation of the tissue at the compressed part is obstructed, and it is easy to lead to pressure sores

[0003] Intraoperative pressure sores usually manifest as local tissue damage but intact epidermis or open ulcers, accompanied by pain. Most pressure sore injuries suffered by patients during surgery show symptoms 1-3 days after surgery; intraoperative pressure sores and The operation time is positively correlated. If the patient maintains a surgical position for more than 2 hours, irreversible damage may occur, and the incidence of pressure injury increases by 33% every 30 minutes, and pressure sore injury will inevitably occur after 4 hours; Similarly, this leads to the fact that the matching gel cushion is not completely suitable for all patients, and pressure sores will also appear in varying degrees when the cushion is pressed for a long time. The lithotomy position operating table is of great significance in reducing or eliminating intraoperative pressure sores
