Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a shoulder support for surgical positioning. Background Technology

[0002] A shoulder support for surgical positioning is a medical assistive device mainly used to help patients maintain a specific position during surgery, especially when the surgery involves the shoulder, neck, chest and abdomen. By supporting and fixing the shoulder, it ensures the exposure of the surgical operating space, the stability and comfort of the patient's position, and reduces the risk of pressure sores and nerve damage caused by prolonged fixation.

[0003] However, existing shoulder supports for surgical positioning have the following drawbacks:

[0004] (1) The existing shoulder support used for surgical positioning has a weak function of flexible adjustment. The existing device cannot be rotated and adjusted flexibly at multiple angles, which may prevent the device from accurately fitting the patient's shoulder position and may cause poor device positioning effect.

[0005] (2) The existing shoulder support for positioning patients in surgery has a weak anti-slip function. The existing device needs to be installed at the edge of the bed, which may cause the device to fall off accidentally due to accidental contact or instability during installation.

[0015] 1. The shoulder support used for positioning patients during surgery is designed with a fixed rod, a fixed shaft, a connecting shaft, positioning bolts, a universal ball joint, a movable sleeve, a fixed sleeve, and a shoulder support plate. During use, after medical staff install the device, they rotate the connecting shaft inside the fixed shaft on the fixed rod, causing the connecting shaft to rotate the connecting rod at an angle. The positioning bolts are then screwed into the connecting shaft and the fixed shaft to fix their angles. Next, the movable sleeve on the universal ball joint at one end of the connecting rod is rotated, causing the movable sleeve to rotate the shoulder support plate at an angle, allowing the shoulder support plate to fit against the patient's shoulder. The fixed sleeve is then screwed onto the movable sleeve to fix the angle of the universal ball joint and the shoulder support plate. This design allows medical staff to easily adjust the device at multiple angles, ensuring the shoulder support plate stably fits against the patient's shoulder.

[0016] 2. The shoulder support used for positioning patients during surgery is configured with a positioning plate, threaded rod, connecting plate, connecting cylinder, positioning cylinder, adjusting bolt, and pressure ball. During use, medical staff place the positioning plate against the edge of the bed, pass the connecting plate through the threaded rod, and screw the connecting cylinder onto the threaded rod, clamping the positioning plate and connecting plate against the edge of the bed. After installation, rotating the adjusting bolt on the top of the positioning cylinder on the positioning plate and connecting plate moves the pressure ball, clamping it firmly onto the bed. This configuration uses a double positioning structure to install the device on the bed, preventing accidental detachment or damage. Attached Figure Description
