Description

Technical Field

[0001] The present invention relates to the technical field of adjustable-angle surgical patient position fixing devices, and particularly to an adjustable-angle surgical patient position fixing device. Background Art

[0002] During the surgical process, the precise fixation of the patient's position is of utmost importance. A suitable and stable position not only provides a clear view for surgical operations, facilitating the doctor to perform the surgery precisely, but also maximally ensures the comfort and safety of the patient during the operation. However, traditional surgical patient position fixing devices have many drawbacks. Traditional fixing devices are extremely limited in terms of angle adjustment and are difficult to meet the diverse needs of different surgical types and doctors' operating habits for the patient's position. For example, in some complex orthopedic surgeries, doctors need to precisely adjust the angle of the patient's limb according to the location of bone lesions and the surgical approach, but traditional devices cannot flexibly achieve multi-angle and high-precision adjustment, resulting in inconvenient surgical operations, prolonged surgical time, and increased surgical risks. The fixing effect of traditional fixing devices is not ideal. During a long surgical process, the patient may experience a shift in position due to muscle relaxation, natural body movement, etc., affecting the surgical process. Especially in some large-scale surgeries that require the patient to maintain a specific position for several hours, traditional fixing devices cannot effectively maintain the patient's position, easily causing changes in the surgical field of view, interfering with the doctor's operation, and even potentially leading to surgical mistakes. Based on this, an adjustable-angle surgical patient position fixing device is proposed to solve the above problems. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides an adjustable-angle surgical patient position fixing device, which solves the problem that during a long surgical process, the patient may experience a shift in position due to muscle relaxation, natural body movement, etc., affecting the surgical process.

By adjusting the position of the second limiting rod in the limiting holes evenly opened in the transverse sliding rod, the transverse position of the transverse sliding rod in the sliding rod can be adjusted.

[0012] By means of the above technical solutions, the present invention provides an adjustable-angle surgical patient body position fixing device, which has at least the following beneficial effects: 1. In the adjusting assembly of the present invention, the longitudinal sliding sleeve can flexibly adjust the height of the sliding rod through the first limiting rod, and the transverse sliding rod at the top of the sliding rod can also achieve transverse position adjustment through the second limiting rod; in the limiting assembly, the hinge seat enables the semi-circular clamping plate to rotate around it, and the distance between the semi-circular clamping plates can also be adjusted through the fastening bolts.

[0013] 2. The supporting legs and supporting stand of the receiving assembly of the present invention provide a stable supporting foundation for the entire device; the design of the limiting assembly further strengthens the fixing effect. When the patient's body position changes slightly, the movable sliding rod on the inner wall of the mounting frame, under the action of the limiting spring, through the cooperation of the connecting rod, the limiting connecting rod, the rotating plug block and the rotating sleeve, enables the receiving pad to adaptively adjust the angle, always closely fit the patient's body, and effectively prevent the patient's body position from shifting during the operation. This can not only avoid interference with the doctor's operation due to changes in body position, but also reduce surgical risks, ensure the safety of patients during surgery, and ensure that the operation can be smoothly implemented according to the predetermined plan.

[0014] 3. The design of the movable assembly of the present invention makes it easy and convenient to adjust the position of the device in the operating room. The movable slider in the limit slide can flexibly drive the movable slide to move. When the position needs to be fixed, the insertion rod can be quickly inserted into the limit hole of the limit slide, and the operation is simple and fast. The height and lateral position adjustment of the adjustment assembly, as well as the angle and spacing adjustment of the limit assembly, can be completed by simply screwing the limit rod and tightening the bolts.
