Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a patient lifting system for supporting intraoperative replacement of a bed surface. Background Art

[0002] When the existing composite operating table is used to replace the bed surface during surgery, the patient is carried to the side of the operating table and waits for the bed surface replacement to be completed before being carried back to the bed surface. In this way, the patient will temporarily leave the relatively sterile area, which not only increases the time and complexity of the operation, but also may destroy the sterile environment of the surgical field and increase the risk of intraoperative infection. The existing operating table can only be replaced manually, which is time-consuming and labor-intensive, and has significant intraoperative risks. During the operation, the patient needs to leave the relatively sterile area when the existing composite operating table is used to replace the bed surface, which not only increases the time and complexity of the operation, but also may destroy the sterile environment of the operating room and increase the risk of infection for the patient.
