AI Technical Summary
Existing positioning frames are difficult to adjust during use, cannot meet the needs of patients with different body types and sizes, and have low practicality.
An adjustable positioning frame was designed, including components such as a connecting seat, an arc-shaped positioning rail, an angle rod, a positioning pin, a connecting pin shaft, a transmission link, a return spring, a paddle, and an upper limb fixation groove. By adjusting the angle rod, the connecting tube, and the universal ball joint, various configuration methods can be achieved to adapt to different patients.
The adaptability and ease of adjustment of the positioning frame have been improved, ensuring the reliability of fixation and the user experience.

Abstract
Claims
1. An adjustable body positioner characterized by, include Connecting seat (2), which is fixed to the bed body; Arc-shaped positioning bar (3), which is fixed to the connecting seat, and has multiple positioning teeth arranged at intervals along the circumferential direction on the lower periphery; Angle rod (4), the bottom end of which is hinged to the connecting seat, the hinge axis coincides with the center of the arc-shaped tooth row formed by the positioning teeth on the arc-shaped positioning rail; The positioning pin (5) is hinged to the angle rod in the middle. One end of the positioning pin is bent to form an insertion end that can be inserted into the gap between the positioning teeth. The other end is connected to a connecting pin. The connecting pin is connected to one end of the transmission link and one end of the return spring respectively. The transmission link (64) and the return spring (53) extend from the connecting pin in opposite directions respectively. The other end of the transmission link is hinged to the lever, and the lever is hinged to the angle rod. By moving the lever, the positioning pin can be flipped through the transmission link so that its insertion end is disengaged from the tooth gap. The other end of the return spring is sleeved on the fixing bolt screwed to the bottom end of the angle rod, and is always in a tensile state; A connecting tube is fixed to the top of the angle rod, and a locking bolt is screwed onto the connecting tube. It also includes an upper limb fixation groove (9), which is connected to an upper limb connecting rod.
2. The adjustable body positioner of claim 1, wherein: There are two arc-shaped positioning rails, which are fixed side by side with a fixed gap between them, and the angle rod passes through the gap between the two arc-shaped positioning rails.
3. The adjustable body positioner of claim 1, wherein: A bushing is fixed to the bottom end of the angle rod. The bushing is rotatably sleeved on the pin, and the pin is fixed on the connecting seat.
4. The adjustable body positioner of claim 1, wherein: There are two positioning pins, symmetrically arranged on both sides of the angle rod; the insertion ends of the two positioning pins are integrally connected and fixed, and the other ends are respectively connected to the two ends of the connecting pin shaft.
5. The adjustable body positioner of claim 1, wherein: The paddle includes a main body, from which two branches extend: a first branch and a second branch. The top of the first branch is hinged to the angle rod via a first branch pin, and the top of the second branch is connected to a second branch pin, which is connected to the top of the transmission link.
6. The adjustable body positioner of claim 1, wherein: The connecting seat is C-shaped, including a lower horizontal plate, a middle vertical plate, and an upper horizontal plate. The lower horizontal plate is equipped with at least one set of lifting clamping units. The lifting clamping unit includes a lifting clamping piece located between the upper and lower horizontal plates. The lifting clamping piece is rotatably connected to the top end of a lifting screw. The lifting screw is screwed through the lower horizontal plate. A toggle rod is passed through the bottom end of the lifting screw. The lifting clamping piece is also fixed to the top end of at least one guide rod. The guide rod slides through the lower horizontal plate and is parallel to the axis of the lifting screw.
7. The adjustable body positioner of claim 1, wherein: The upper limb connecting rod consists of a vertical rod and a horizontal rod. The vertical rod is used to fit into the connecting tube, and the outer end of the horizontal rod is connected to the upper limb fixing groove through a universal joint.
8. The adjustable body positioner of claim 1, wherein: The upper limb fixation groove has multiple holes for threading the restraint straps.
9. The adjustable body positioner of claim 1, wherein: An insulating pad is also adhered to and covered on the inner wall of the upper limb fixation groove.
10. The adjustable body positioner of claim 1, wherein: An intermediate connecting rod is added between the connecting tube of the angle rod and the upper limb connecting rod. The intermediate connecting rod includes a vertical rod body and a horizontal rod body. The vertical rod body is used to fit into the connecting tube of the angle rod. The end of the horizontal rod body of the intermediate connecting rod is fixed to a second connecting tube. The second connecting tube is also equipped with a locking bolt for locking the second connecting tube to the upper limb connecting rod.
