In the preferred embodiment, the position chair is fixed on the operating bed rail by using the transversely adjustable bed rail fixing module 060. After the position chair is fixed on the operating bed, the doctor can adjust the angle between the back of the operator and the operating bed by adjusting the gas spring elevation angle adjustment module 050 according to the operator's position requirements; in addition, by adjusting the head fixed adjustable ball head double joint universal adjustment structure 012, the height and direction angle of the head fixing module 010 are adjusted according to the operator's height and head fixed posture, allowing various inclination angles, rotations, and forward and backward sliding, so as to ensure that the operator's head maintains a suitable position and direction during surgery. After the head position and direction are fixed, the locking nut of the head fixing structure is locked, and the gas spring adjustment control lever is loosened after the operator's lying elevation angle and head position are adjusted and fixed, and the position chair backrest elevation angle, body position and head are fixed. Then, according to the width between the upper limb shoulder and elbow of the operator, the upper limb transverse adjustable structure module 030 is adjusted to a suitable position and then locked and fixed by locking the upper limb transverse adjustable hexagonal shaft locking nut 033. The shoulder backrest board 021 can be adjusted laterally according to the surgeon's left or right shoulder. When the left shoulder is operated, the shoulder backrest board 021 is adjusted to the right to expose the left shoulder operation area.

Through the universal adjustment structure of the double joint ball head device 012, the universal direction of the two-way bending connecting rod 0137 and the arc sponge pad 0131 for fixing the head can be adjusted, and the head fixing adjustable double joint locking nut 014 can be locked after adjusting to the appropriate position. When the head fixing structure locking nut 011 is loosened, the double bending connecting rod 0137 will drive the arc sponge pad 0131 fixed thereto to move forward and backward along the axis of the two-way bending connecting rod 0137, and then the head fixing structure locking nut 011 is locked after moving to the appropriate position. Here, after the head-fixing adjustable double-joint locking nut 014 and the head-fixing structure locking nut 011 are locked, the position and direction of the head-fixing module are completely fixed. The square openings on both sides of the arc-shaped gasket 0134 are designed to facilitate the insertion of the head-fixing belt structure. The openings on both sides of the upper end are for fixing the forehead bandage connection and fixation, and the openings on both sides of the lower end are for fixing the chin bandage connection and fixation. The double-bend connecting rod 0137 is designed with a hexagonal structural profile to prevent radial rotation of the fixed head module, thereby affecting the overall fixation of the operator's head. During the operation, the medical staff will loosen or lock the head-fixing adjustable double-joint locking nut 014 and the head-fixing structure locking nut 011 according to the patient and surgical needs, and at the same time adjust the head arc sponge pad to the appropriate position and then fix the locking nuts 014 and 011, thereby achieving the positioning of the head fixation module 010.

When sliding, the two slide left and right together along the slider 023. The back cushion 026 is bonded to the back backboard 021 by adhesive strips, and there will be no movement or axial displacement between the two after bonding. The shoulder backboard 024 and the back backboard 022 are fixed to the overall support structure such as the support structure reinforcement structure 041, the support shoulder and back fixing block 046 and other structures by threaded connection. Therefore, when the gas spring elevation adjustment structure module 050 is working, the back cushion 026 and the shoulder back cushion 025 will be driven by the overall support structure 040 to achieve the elevation adjustment of the operator.

To prevent axial rotation along the axis of the adjustment fixing plate connecting plate 034, two fixing screws 036 are used for threaded fixation; the adjustment fixing plate connecting plate 034 and the upper limb transversely adjustable hexagonal shaft 031 are connected and fixed by a threaded structure by the arm connecting plate fixing screws 038; the upper limb transversely adjustable hexagonal shaft 031 adopts a hexagonal equilateral structure design, which can prevent the arm cushion 035 from rotating as a whole in the radial direction of the upper limb transversely adjustable hexagonal shaft 031; The upper limb transverse adjustable hexagonal shaft 031 and the upper limb transverse adjustable hexagonal shaft fixing block 032 are locked and fixed by the upper limb transverse adjustable hexagonal shaft locking nut 033 with a threaded structure; the upper limb transverse adjustable hexagonal shaft fixing block 032 is fixed on the support rod 045 through a round hole structure; when the upper limb transverse adjustable hexagonal shaft locking nut 033 is loosened, the arm cushion 035 can move in both directions of the hexagonal shaft through the gap between the upper limb transverse adjustable hexagonal shaft 031 and the upper limb transverse adjustable hexagonal shaft fixing block 032. During the operation, the medical staff adjusts the upper limb transverse adjustable hexagonal shaft to a suitable position according to the surgeon's body shape and surgical needs, and then locks the upper limb transverse adjustable hexagonal shaft locking nut 033, thereby realizing the position fixation of the upper limb transverse adjustable structure module 030. See for details. Figure 3 .

[0047] Furthermore, the transversely adjustable bed rail fixing module 060 includes: a transversely adjustable bed rail hexagonal shaft 061 and a transversely adjustable bed rail fixing clamp 062; the transversely adjustable bed rail hexagonal shaft 061 is connected to the gas spring adjustment module fixing seat 052; the transversely adjustable bed rail fixing clamp 062 is connected to the transversely adjustable bed rail hexagonal shaft 061.

The head fixing module 010 is provided with a double-joint locking nut 014. The backrest module 020 includes: a shoulder-rest backrest plate 021 and a backrest connecting support rod structure 022; the shoulder-rest backrest plate 021 and the backrest connecting support rod structure 022 are respectively connected to the overall support structure module 040. In the preferred example, the overall support structure module 040 includes: support structure reinforcement ribs 041, support structure fixing seat 042, support structure vertical bottom plate 043, support structure horizontal bottom plate 044, and support rod 045. The overall support structure is composed of two support structure fixing seats 042, two support rods 045 and three support structure reinforcement ribs 041 connected by threads. The reinforcement ribs are used to enhance the stability of the body position chair structure and connect other components at the same time. The gas spring elevation adjustment structure module 050 includes: a gas spring adjustment control handle 051, a gas spring adjustment module fixing seat 052, a handle connecting rod 053, a handle connecting rod locking screw 0507, a locking screw gasket 0508, a handle connecting rod fixing seat 0505, a handle connecting rod slot block 054, a slot block locking screw 0506, a slot block locking nut 055, a piston rod 057, a cylinder 058, a piston rod nut 175, a cylinder 177, a piston rod connecting fixing piece 178, a gas spring fixing base 179, a gas spring fixing nut 0509, a base fixing plate 044, a base fixing nut 0503, and a ground contact base plate 043. The gas spring is an accessory that can perform functions such as support, buffering, braking, height adjustment and angle adjustment. The invented product uses a self-locking gas spring structure to adjust the backrest elevation angle: when the gas spring adjustment control handle 051 is pressed down, the gas spring is in a free movable state, and the overall backrest elevation angle can be adjusted to any angle within 90°, and then the locking and fixing is stopped. Then the control handle 051 is released, and the backrest elevation angle adjustment is completed. When the control handle 051 is pressed down, the piston rod 057 is in a free state and can be extended or shortened. When extended, the overall backrest elevation angle becomes smaller. At this time, the gas spring fixed base 052 hinged to the piston rod 057 drives the base fixing plate 044 fixed thereto and the base plate 043 in contact with the ground to move upward, thereby causing the backrest elevation angle to become smaller. Conversely, the backrest elevation angle becomes larger. Medical staff will adjust the backrest elevation angle to a reasonable position according to the operator's surgical needs and the doctor's surgical operation, thereby ensuring the smooth completion of the operator's surgery. For details, see Figure 4. In the preferred embodiment, the guide rail slider 1081 is installed on the bed rail fixing module.

Before the operation, the medical staff lifts the position chair, aligns the fixed rails 187 on both sides and the bed rail locking slots 181 with the operating bed rails, and pushes the position chair forward along the operating bed rails. When it cannot be pushed further, adjust the bed rail locking slots 181 to the appropriate position of the operating bed rails, tighten the bed rail locking nuts 186, and tighten the slot locking nut handles 185 clockwise at the same time, and then place the slot locking nut handles 185 in the operating bed rails. Figure 5 At the position shown, the locking nut 183 is rotated clockwise along the radial direction of the slot to lock it. After the bed rail locking nut 186 and the slot locking nut 183 are locked at the same time, the position chair will be fixed on the operating table without movement or shaking. The size design of the bed rail locking slot 181 is suitable for all operating tables on the market, increasing the market share of the invented product.
