Description

Technical Field

[0001] The utility model relates to an auxiliary instrument for an operating room, and more specifically, to a multifunctional traction auxiliary device during surgery. Background Art

[0002] Orthopedic surgery can be roughly divided into two categories: spine surgery and limb surgery. Due to the influence of surgical incisions, intraoperative reduction, internal fixation, intraoperative traction, radiography, etc., orthopedic patients have relatively high requirements for surgical positions, requiring full exposure of the surgical field to ensure smooth operation. One of the surgical characteristics of orthopedic surgery is that it is often necessary to adjust the patient's position during surgery (such as traction, correction of deformities, fracture reduction, and temporary extension of incisions, etc.). Therefore, it is necessary for circulating nurses to place and change the position at any time before and during surgery according to the operator's habits and the patient's actual state, so as to facilitate the operator's operation. In limb surgeries, especially joint surgeries, it is often necessary to adjust the angle and height of the upper or lower limbs according to the patient's surgical site and the operator's habits. The existing traction or lifting devices for patients' limbs cannot achieve the function of adjusting the limb state, and nurses are required to manually place, or even lift and maintain the patient's limb state. However, due to the limited physical strength of clinical nurses, they are unable to maintain a stable position during surgery. Even considering the patient's body shape, sometimes they need the assistance of multiple medical staff to complete the adjustment of the patient's surgical posture, which greatly affects the progress of the operation.
