Description
Technical Field
The invention relates to the field of medical instruments, in particular to an operation table for an lithotomy position.
Background
The lithotomy position is a body position commonly used in department operations such as general surgery, gynecology, urology and the like, and is characterized in that a patient lies on the back, the hip is moved to the bedside, and the two legs are placed on a leg frame, so that the lithotomy position is commonly used in operations such as gynecological perineum and laparoscopic surgery, rectal surgery, urological surgery, cystoscope surgery and the like; the operation patient in the anesthesia state basically loses the normal adjusting capability due to partial or whole loss of consciousness, muscle relaxation and no force, and the weakening or loss of protective reflex action, and the body position is also an operation body position which is easy to cause complications, is most easy to cause injury in clinic and brings unnecessary pain to the patient; when the lithotomy position is adopted, the pressed parts of the body of a patient are all the parts with thin muscles and fat at the sacral caudal part, the shoulders, the spine and the like, and in the long-time operation process, the microcirculation of the tissues of the pressed parts is obstructed due to the extrusion of the body weight of the patient and the conduction of force application in the operation, so that the formation of pressure sores is easily caused.
Intraoperative pressure sores usually appear as local tissue damage but with intact or open skin ulceration, with pain, and most intraoperative pressure sore lesions present with symptoms for 1-3 days post-surgery; during operation, pressure sores are positively correlated with operation time, irreversible injury can occur when a patient keeps an operation position for more than 2 hours, the occurrence rate of pressure injury is increased by 33% every 30 minutes, and pressure sore injury inevitably occurs after the operation lasts for 4 hours; because the patients are different in body types, the matched gel cushion cannot be completely suitable for all patients, and the cushion pressing cushion can generate pressure sore injuries of different degrees for a long time, so that the development of the lithotomy position operating bed which can adapt to various body types of the patients and can reduce or eliminate the pressure sore in the operation has obvious significance.
