Description

Technical Field

[0001] The invention belongs to the technical field of anesthesia nursing, and in particular relates to a patient limb fixing frame for anesthesia nursing and a use method thereof. Background Art

[0002] The patient limb fixator is an auxiliary device designed for patients under anesthesia. Its core function is to ensure the stability of the patient's limbs during treatment and care. The fixator can effectively limit the unconscious movements that may occur under the effect of anesthetics through scientific and reasonable structural design, thereby avoiding interference with the treatment and care process and preventing the accidental fall of surgical instruments. More importantly, it can protect patients from possible injuries caused by uncontrolled limb movement, such as nerve damage, skin compression, etc., to the greatest extent, ensuring the safe and smooth progress of surgery or treatment. It is an indispensable and important tool in anesthesia care.

[0003] In clinical anesthesia nursing practice, the patient limb fixation device is an important auxiliary device for surgical position management, and its operating performance directly affects the nursing efficiency and patient safety during the anesthesia induction and awakening periods. Although the widely used combined fixation frame can achieve multi-dimensional fixation of limbs through bolt connectors and nylon tightening belts, it is found in actual clinical applications that this traditional fixation mode has a significant operational efficiency bottleneck. Specifically, the device assembly process requires medical staff to complete multiple steps such as thread tightening, belt threading, and tension adjustment in sequence. In emergency rescue or batch surgery scenarios, this complex installation process may delay the critical rescue time window, and the operational pain points of traditional fixation devices mainly come from their mechanical structure design. Although bolt connection can ensure structural stability, the screwing operation requires medical staff to maintain a specific angle to apply force, and long-term use can easily lead to wrist strain. Although the one-way locking characteristics of the nylon tightening belt can effectively maintain the restraining force, it completely loses the quick release function. This irreversible fixation method is obviously not compatible with dynamic medical scenarios. Clinical observation data show that in cases of agitation during the recovery period from general anesthesia, it takes an average of 2.3 minutes to completely remove the traditional fixation device, which significantly increases the risk of patients falling out of bed or self-extubation. Summary of the invention

[0004] The object of the present invention is to provide a patient limb fixation frame for anesthesia care and a method of using the same, so as to solve the problem that the existing fixation frame mentioned in the above background technology cannot achieve rapid closing, limiting and separation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a patient limb fixation frame for anesthesia care, comprising a support assembly, which is C-shaped as a whole; a sliding assembly connected to the bottom surface of the support assembly, and the support assembly performs horizontal sliding movement along the sliding assembly; a placement assembly, which is arranged at the top position of the support assembly; the placement assembly comprises a support bracket integrally arranged with the support assembly, and a limit frame arranged just above the support bracket, and both ends of the limit frame are fixed with plug plates vertically penetrating the support bracket; a self-locking mechanism is also arranged inside the support bracket; the self-locking mechanism comprises an inner arc plate vertically penetrating the middle position of the support bracket, a driving assembly arranged below the support bracket, and a locking assembly arranged on both sides of the bottom of the plug plate, the driving assembly is against the inner arc plate, when the inner arc plate descends, it will drive the driving assembly to move, the driving assembly is in transmission connection with the plug plate, so the plug plate can be driven to descend by the driving assembly, and then the limit frame can be driven to descend to achieve self-locking, the locking assembly is unidirectionally locked with the plug plate, so when the limit frame descends, it is ensured that the limit frame will not be lifted again;

[0006] The outer cover is installed on the bottom end surface of the support bracket and covers the driving component to prevent the driving component from being exposed to the outside and being easily damaged.

[0007] As a preferred technical solution in the present invention, an integrated plug rod is fixedly arranged on the bottom end surface of the inner arc plate, the bottom end of the plug rod vertically extends toward the driving assembly, and a lower abutment inclined surface is formed on the bottom end surface of the plug rod; the driving assembly comprises a large toothed disc with an axis, and a transmission gear 2 and a connecting gear which are arranged on both sides of the large toothed disc and meshed with the large toothed disc, and a transmission gear 1 is also arranged obliquely below the connecting gear, and the transmission gear 1 does not contact the large toothed disc, so as to avoid the transmission gear 1 being directly driven by the large toothed disc, thereby ensuring the transmission gear The first gear can receive the transmission torque of the connecting gear, and realize the different rotation directions of the transmission gear 1 and the transmission gear 2, and drive the limit frame to descend, so as to clamp the patient's limbs. The diameter of the large toothed disc is larger than that of the transmission gear 1, the connecting gear and the transmission gear 2. Since the abutting block is at the center of the circle of the large toothed disc, when the large toothed disc rotates a small angle, the arc length distance rotated by the abutting block is larger, and the larger arc length distance is also the distance rotated by the driven transmission gear 1 and the transmission gear 2. Therefore, when the inner arc plate descends, the limit The distance that the frame descends is greater than the distance that the inner arc plate descends, thereby ensuring rapid clamping of the patient's limbs. At the same time, this structural setting can also ensure that a large spacing is left between the limit frame and the supporting frame before placement, which is convenient for inserting the patient's limbs. A tightening block is also fixed to the axial position of the large toothed disc, and the tightening block is abutted against the lower inclined surface. When the inner arc plate is contacted by the patient's limbs, it will drive the insertion rod to descend. At this time, the lower inclined surface squeezes the tightening block, and the large toothed disc is driven to rotate clockwise through the tightening block. When the large toothed disc rotates, it will drive the transmission gear 2 When the locking cam is in motion, the gear shifts back and forth, and the locking cam, when in contact with the locking cam, moves the locking cam back to the original position, which in turn moves the locking cam back to the original position.

[0008] As a preferred technical solution in the present invention, the inner side surface of the plug plate is provided with a tooth groove meshing with the transmission gear 2 and the transmission gear 1, so that the plug plate and the limit frame can be driven to descend under the rotation of the large gear plate, and an inclined groove is provided on the outer surface of the plug plate, and the locking assembly is engaged with the inclined groove for one-way locking.

[0009] As a preferred technical solution in the present invention, the locking assembly includes an oblique abutment plate obliquely arranged between the plug plate and the inner wall of the outer cover, the bottom end of the oblique abutment plate is obliquely inserted downward into the oblique groove, so when the oblique groove moves downward, it will press down against the oblique abutment plate and drive the oblique abutment plate to move obliquely upward, thereby moving the oblique abutment plate from the next oblique groove to the previous oblique groove, and when the patient's limbs swing, the force in the upward movement direction generated will be stopped and limited by the oblique groove and the oblique abutment plate, thereby avoiding the upward movement of the limit frame; side grooves are provided on both sides of the outer cover, and an inner groove is also provided on the inner wall of the bottom opening of the side groove, a limiting oblique plate is fixed in the inner groove, the top of the oblique abutment plate is raised upward, and a slot is provided for the limiting oblique plate to movably pass through, and the inclination of the limiting oblique plate and the oblique abutment plate The cam is in a state of being moved in a downward direction as the cam is moved upward due to the descent of the insert plate, and the cam itself is still moved in an inclined direction, and its own inclination will not change. At the same time, when the patient's limbs need to be separated in the later stage, it is only necessary to move the cam toward the inner groove so that the bottom end of the cam is separated from the cam. In the normal limit position, the cam can always be tilted downward under the action of gravity to ensure one-way locking with the cam. The large toothed disc, the clamping block, the shaft torsion spring, the transmission gear one, the connecting gear and the transmission gear two are all fixedly arranged on the inner wall position of the outer cover to realize the installation of the drive assembly. A protrusion is formed on the bottom end of the limiting slant plate, and the protrusion is locked at the inner wall position of the top of the slant plate that bulges upward, so as to realize the limiting of the slant plate and avoid separation from the slant plate.

[0010] As a preferred technical solution in the present invention, the bottom end surface of the support bracket is provided with an arc groove for the large gear disk to rotate, and through grooves for the insertion rod to pass through are provided on both sides of the arc groove, and the insertion rod is fitted with both sides of the large gear disk; strip grooves for the insertion plate to pass through are also provided at both ends of the support bracket.

[0011] As a preferred technical solution in the present invention, one end of the top of the clamping block is inclined and forms a clamping slope. The clamping slope has the same inclination direction as the lower clamping slope but a different slope. By setting the inclined state, both normal downward pressure and subsequent normal rebound can be guaranteed.

[0012] As a preferred technical solution in the present invention, the support assembly includes a horizontally arranged and frame-shaped main frame, and a horizontal connecting frame with one end rotatably arranged at one end inside the main frame, a mounting block is installed at the other end of the connecting frame, a vertical plate is fixed on the top of the mounting block, an L-shaped support frame is installed on the inner side of the vertical plate by bolts, and the supporting frame is integrally arranged at the end position of the support frame.

[0013] As a preferred technical solution in the present invention, an integrated square block is fixedly arranged on the end face of the mounting block, and a square hole for the square block to be inserted into is opened on the end face of the connecting frame, and an inner mounting stud is fixedly arranged on the end face of the square block, and the inner mounting stud is located inside the connecting frame, and a nut is screwed on the outside of the inner mounting stud, and the nut abuts against the inner wall of the connecting frame, so that the mounting block is tightly installed by tightening the nut; a reinforcing plate is also arranged inside the connecting frame, and the strength of the connecting frame is increased by the reinforcing plate, so that A magnetic plate is also fixed to the rear surface of the connecting frame, and the magnetic plate is magnetically attracted to the inner wall of the main frame, so that it is adsorbed when the connecting frame is rotated and folded toward the inside of the main frame. When the connecting frame is rotated and parallel to the main frame, the mounting block is outside the main frame. A socket is also provided on the top of the connecting frame, and a stud in the socket penetrates the top of the main frame. The stud is used to limit and fix the expansion angle between the main frame and the connecting frame, ensuring that in normal use, the connecting frame will not rotate and move toward the inside of the main frame due to the collision of external force.

[0014] As a preferred technical solution in the present invention, the sliding assembly includes a slider fixed on the main frame, and also includes two sliding rods that movably pass through the slider. The surface of the sliding rod is provided with a tightening groove, and the surface of the slider is also screwed with a tightening bolt extending into the tightening groove. The position of the slider on the tightening groove is fixed by the tightening of the tightening bolt and the tightening groove, so as to achieve limited fixation of the specified position of the patient's limb. End plates are also fixed at both ends of the sliding rod, and the entire device is installed on the specified position or object through the end plates.

[0015] The present invention also discloses a method for using a patient limb fixation frame for anesthesia care, comprising a limb fixation frame, and the specific steps are as follows:

[0016] Step 1: According to the position of the patient's limbs, slide the slider on the slide bar, and at the specified position, insert the locking stud through the slider and lock it in the locking groove to fix it;

[0017] The second step is to place the patient's limb in the inner arc plate. At this time, the inner arc plate drives the insertion rod to descend, and the lower inclined surface squeezes the tightening inclined surface, and the large toothed disc is synchronously driven to rotate clockwise through the small-angle rotation of the tightening block, and the arc length of the large angle is rotated at the outer peripheral position of the large toothed disc, and the tightening block will synchronously squeeze the torsion spring with the shaft during the rotation; when the large toothed disc rotates, it will drive the transmission gear 2 to rotate counterclockwise and the connecting gear to rotate counterclockwise, and the transmission gear 1 will rotate clockwise under the drive of the connecting gear, and finally, through the meshing transmission of the transmission gear 2 and the transmission gear 1 with the tooth groove, the insertion plate is driven downward, thereby clamping the patient's limb, and when the insertion plate descends, the inclined groove moves downward synchronously, and will press the inclined plate downward, and the inclined plate moves obliquely upward after being pressed, thereby moving the inclined plate from the next inclined groove to the previous inclined groove, and when the patient's limb swings, the force generated in the upward direction will be stopped and limited by the inclined groove and the inclined plate, so as to avoid the upward movement of the limit frame;

[0018] Step 3: When the patient's limbs need to be separated at a later stage, the oblique abutment plate is moved toward the inner groove so that the bottom end of the oblique abutment plate is separated from the oblique groove;

[0019] Step 4: When you need to flip the vertical plate, support frame, placement component, and outer cover for placement later, first loosen the nuts on the inner mounting studs, then flip the mounting block vertical plate, support frame, placement component, and outer cover as a whole, so that the blocks can be swapped in the square holes, and finally tighten the inner mounting studs with nuts, and press them against the inner wall of the connecting frame, then pull the studs out of the sockets, screw the connecting frame into the main frame, and connect them through magnetic attraction on the magnetic plate to achieve placement.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, a gravity adaptive self-locking mechanism is adopted to realize the autonomous fixation and quick release of the patient's limbs through precision mechanical transmission. Specifically, after the inner arc plate supports the patient's limbs, it will fall by receiving the gravity of the limbs, and at the same time drive the upper limit frame to fall, so as to realize the fixed limit of the limbs. The whole process can complete the constraint without external power input. At the same time, the present invention adopts the method of oblique abutment plate to ensure that the limit frame will not move up due to the swing of the limbs during the limit of the patient's limbs. When separation is required in the later stage, it is only necessary to pull the oblique abutment plate, and the limit frame will be lifted under the action of the belt shaft torsion spring, and return to the original position to prepare for the next fixed limit. Compared with the traditional shear-type fixing belt, this reversible release structure can be reused many times and the disassembly time is short.

[0022] 2. Through the designed mounting block, the vertical board, the support frame and the entire placement assembly can be flipped to a certain angle, and corresponding adjustments can be made according to usage requirements. The overall flexibility is high. When idle, the main frame and the connecting frame can be rotated and folded to reduce the space occupied by the entire device. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 12 The present invention provides a technical solution: a patient limb fixation frame for anesthesia care, comprising

[0043] The support assembly 100 is C-shaped as a whole;

[0044] The sliding assembly 200 is connected to the bottom surface of the supporting assembly 100, and the supporting assembly 100 performs horizontal sliding motion along the sliding assembly 200;

[0045] The placement component 300 is arranged at the top position of the support component 100; the placement component 300 includes a support bracket 301 integrally arranged with the support component 100, and a limit frame 303 arranged just above the support bracket 301, and the two ends of the limit frame 303 are fixed with plug plates 302 that vertically penetrate the support bracket 301; a self-locking mechanism is also arranged inside the support bracket 301; the self-locking mechanism includes an inner arc plate 304 that vertically penetrates the middle position of the support bracket 301, and a stopper 303 arranged on the support bracket 301. 1, and the locking components arranged on both sides of the bottom of the plug plate 302, the driving component is against the inner arc plate 304, when the inner arc plate 304 descends, it will drive the driving component to move, the driving component is in transmission connection with the plug plate 302, so the plug plate 302 can be driven to descend by the driving component, and then the limit frame 303 can be driven to descend to achieve self-locking, the locking component is unidirectionally locked with the plug plate 302, so when the limit frame 303 descends, it is ensured that the limit frame 303 will not be lifted again;

[0046] The outer cover 400 is installed on the bottom surface of the support bracket 301 and covers the driving assembly to prevent the driving assembly from being exposed to the outside and being easily damaged.

[0047] In this embodiment, an integrated plug rod 304a is fixed to the bottom end surface of the inner arc plate 304, and the bottom end of the plug rod 304a extends vertically toward the drive assembly, and a lower inclined surface 304b is formed on the bottom end surface of the plug rod 304a; the plug rod 304a drive assembly includes a large toothed disc 501 with an axis, and a transmission gear 2 506 and a connecting gear 505 arranged on both sides of the large toothed disc 501 and meshing therewith, and a transmission gear 1 504 is also arranged obliquely below the connecting gear 505, and the transmission gear 1 504 does not contact the large toothed disc 501, so as to avoid the transmission gear 1 504 being directly driven by the large toothed disc 501, and ensure that the transmission gear 1 504 can only receive The transmission torque of the connecting gear 505 is realized, and the rotation directions of the transmission gear 1 504 and the transmission gear 2 506 are different, and the limit frame 303 is driven to descend, so as to clamp the patient's limbs. The diameter of the large toothed disc 501 is larger than that of the transmission gear 1 504, the connecting gear 505, and the transmission gear 2 506. Since the abutting block 502 is located at the center of the large toothed disc 501, when the large toothed disc 501 rotates a small angle, the arc length distance rotated by the abutting block 502 is large, and the large arc length distance is also the distance rotated by the driven transmission gear 1 504 and the transmission gear 2 506. Therefore, when the inner arc plate 304 descends, the limit frame 303 descends. The distance is greater than the distance that the inner arc plate 304 descends, thereby ensuring rapid clamping of the patient's limbs. At the same time, this structural setting can also ensure that before placement, a large spacing is left between the limit frame 303 and the support frame 301, which is convenient for inserting the patient's limbs. A tightening block 502 is also fixed to the axial position of the large toothed disc 501, and the tightening block 502 is against the lower inclined surface 304b. When the inner arc plate 304 is contacted by the patient's limbs, it will drive the insertion rod 304a to descend. At this time, the lower inclined surface 304b squeezes the tightening block 502, and the large toothed disc 501 is driven to rotate clockwise through the tightening block 502. When the large toothed disc 501 rotates, it will drive the transmission gear 2 506 to rotate counterclockwise. When the locking cam 502 is in the unlocked state, the locking cam 503 is in the unlocked state, and the locking cam 503 is in the unlocked state.

[0048] In this embodiment, the inner side surface of the plug plate 302 is provided with a tooth groove 302a that is meshed with the transmission gear 2 506 and the transmission gear 1 504, so that the plug plate 302 and the limit frame 303 can be driven to descend under the rotation of the large toothed disc 501, and the outer surface of the plug plate 302 is provided with an inclined groove 302b, and the locking component is engaged with the inclined groove 302b for one-way locking.

[0049] In this embodiment, the locking assembly includes an oblique abutment plate 507 obliquely arranged between the plug plate 302 and the inner wall of the outer cover 400, and the bottom end of the oblique abutment plate 507 is obliquely inserted downward into the oblique groove 302b. Therefore, when the oblique groove 302b moves downward, it will push down against the oblique abutment plate 507 and drive the oblique abutment plate 507 to move obliquely upward, thereby moving the oblique abutment plate 507 from the next oblique groove 302b to the previous oblique groove 302b. When the patient's limbs swing, the force generated in the upward direction The outer cover 400 is provided with side grooves 400a on both sides, and an inner groove 400b is provided on the inner wall of the bottom opening of the side groove 400a. A limiting inclined plate 508 is fixed in the inner groove 400b. The top of the inclined plate 507 is raised upward and is provided with a slot 507a for the limiting inclined plate 508 to pass through. The limiting inclined plate 508 and the inclined plate 507 are interlocked. The inclination of the inclined plate 507 is equal, so when the inclined plate 507 moves upward due to the descent of the plug plate 302, the entire plate is still pushed in the inclined direction, and its own inclination will not change. At the same time, when the patient's limbs need to be separated in the later stage, it is only necessary to move the inclined plate 507 toward the direction of the inner groove 400b so that the bottom end of the inclined plate 507 is separated from the inclined groove 302b. In the normal limit position, the inclined plate 507 can always tilt downward under the action of gravity to ensure that it is aligned with the inclined groove 302b. 2b is a one-way stop; both ends of the large toothed disc 501, the tightening block 502, the shaft torsion spring 503, the transmission gear 1 504, the connecting gear 505, and the transmission gear 2 506 are fixedly arranged on the inner wall position of the outer cover 400, so as to realize the installation of the drive component; a protrusion is formed at the bottom end of the limiting inclined plate 508, and the protrusion is stopped at the inner wall position of the upward protrusion at the top of the inclined abutment plate 507, so as to realize the limitation of the inclined abutment plate 507 and avoid separation from the inclined abutment plate 507.

[0050] In this embodiment, an arc groove 301b is provided on the bottom end surface of the support bracket 301 for the large toothed disc 501 to rotate, and through grooves 301c are provided on both sides of the arc groove 301b for the insertion rod 304a to pass through, and the insertion rod 304a is fitted with both sides of the large toothed disc 501; strip grooves 301a are also provided at both ends of the support bracket 301 for the insertion plate 302 to pass through.

[0051] In this embodiment, one end of the top of the clamping block 502 is inclined and forms a clamping slope 502a. The clamping slope 502a has the same inclination direction as the lower clamping slope 304b, but a different slope. By setting the inclined state, both normal downward pressure and subsequent normal rebound can be guaranteed.

[0052] In this embodiment, the support assembly 100 includes a main frame 101 that is horizontally arranged and frame-shaped, and a horizontal connecting frame 102 with one end rotatably set on the inner end of the main frame 101. A mounting block 103 is installed at the other end of the connecting frame 102. A vertical vertical plate 104 is fixed on the top of the mounting block 103. An L-shaped support frame 105 is installed on the inner side of the vertical plate 104 by bolts, and the supporting frame 301 is integrally arranged at the end position of the support frame 105.

[0053] In this embodiment, an integrated block 103b is fixedly provided on the end surface of the mounting block 103, and a square hole for the block 103b to be inserted is opened on the end surface of the connecting frame 102. When the mounting block 103 needs to be rotated and folded, the mounting block 103 is flipped over, and the block 103b will flip over at an angle of 90° in the square hole, thereby realizing the flip adjustment of the angle. An inner mounting stud 103a is also fixedly provided on the end surface of the block 103b, and the inner mounting stud 103a is located inside the connecting frame 102, and a nut is screwed on the outside of the inner mounting stud 103a, and the nut is abutted against the inner wall of the connecting frame 102, so that the mounting block 103 is tightly installed by tightening the nut; a reinforcing plate 103 is also provided inside the connecting frame 102. 2b, the strength of the connecting frame 102 is increased by a reinforcing plate 102b, and a magnetic plate 102c is also fixed to the rear surface of the connecting frame 102, and the magnetic plate 102c is magnetically attracted to the inner wall of the main frame 101, so that the connecting frame 102 is adsorbed when it is rotated and folded toward the inside of the main frame 101. When the connecting frame 102 is rotated and parallel to the main frame 101, the mounting block 103 is outside the main frame 101; a socket 102a is also provided on the top of the connecting frame 102, and a stud in the socket 102a penetrates the top of the main frame 101, and the unfolding angle between the main frame 101 and the connecting frame 102 is limited and fixed by the stud, so as to ensure that in normal use, the connecting frame 102 will not rotate and move toward the inside of the main frame 101 due to the collision of external force.

[0054] In this embodiment, the sliding assembly 200 includes a slider 204 fixed on the main frame 101, and also includes two sliding rods 202 that movably pass through the slider 204. A tightening groove 203 is opened on the surface of the sliding rod 202, and a tightening bolt extending into the tightening groove 203 is screwed into the surface of the slider 204. The position of the slider 204 on the tightening groove 203 is fixed by the tightening of the tightening bolt and the tightening groove 203, so as to achieve the limit fixation of the designated position of the patient's limb. End plates 201 are also fixed at both ends of the sliding rod 202, and the entire device is installed on a designated position or object through the end plates 201.

[0055] The present invention also discloses a method for using a patient limb fixation frame for anesthesia care, comprising a limb fixation frame, and the specific steps are as follows:

[0056] Step 1: According to the position of the patient's limb, slide the slider 204 on the slide bar 202, and at the designated position, insert a tightening stud through the slider 204 and tighten it in the tightening groove 203 to achieve fixation;

[0057] Step 2: Place the patient's limb in the inner arc plate 304. At this time, the inner arc plate 304 drives the insertion rod 304a to descend, and the lower inclined surface 304b squeezes the inclined surface 502a, and the large toothed disc 501 is synchronously driven to rotate clockwise through the small-angle rotation of the tightening block 502, and rotates a large-angle arc length at the outer periphery of the large toothed disc 501, and the tightening block 502 will synchronously squeeze the shaft torsion spring 503 during the rotation; when the large toothed disc 501 rotates, it will drive the transmission gear 2 506 to rotate counterclockwise and the connecting gear 505 to rotate counterclockwise, and the transmission gear 1 504 will rotate clockwise under the drive of the connecting gear 505 The second transmission gear 506 and the first transmission gear 504 are meshed with the tooth groove 302a to drive the insert plate 302 downward, thereby clamping the patient's limbs. When the insert plate 302 is descending, the inclined groove 302b moves downward synchronously and presses against the inclined plate 507. After being pressed, the inclined plate 507 moves upward obliquely, thereby moving the inclined plate 507 from the next inclined groove 302b to the previous inclined groove 302b. When the patient's limbs swing, the upward movement force generated will be stopped by the inclined groove 302b and the inclined plate 507, thereby preventing the limit frame 303 from moving upward.

[0058] Step 3: When the patient's limbs need to be separated at a later stage, the oblique abutment plate 507 is moved toward the inner groove 400b so that the bottom end of the oblique abutment plate 507 is separated from the oblique groove 302b;

[0059] Step 4: When it is necessary to flip the vertical plate 104, the support frame 105, the placement component 300, and the outer cover 400 for placement later, first loosen the nut on the inner mounting stud 103a, and then flip the mounting block 103, the vertical plate 104, the support frame 105, the placement component 300, and the outer cover 400 as a whole, so that the block 103b is swapped in the square hole, and finally the inner mounting stud 103a is locked with the nut, and pressed against the inner wall of the connecting frame 102, and then the stud is pulled out of the socket 102a, and then the connecting frame 102 is screwed into the main frame 101, and is magnetically connected through the magnetic plate 102c to achieve placement.
