[0029] like Fig.12 As shown, it also includes a second elastic wedge block 1001, and the inner wall of the thigh support 203 is slidably connected to the second elastic wedge block 1001. The other side of the arc-shaped pad 204 is provided with a second slot for use with the second elastic wedge block 1001. When the second elastic wedge block 1001 is inserted into the second slot, the arc-shaped pad 204 can be limited.

[0030] Initially, the two plug-in frames 201 are respectively inserted into the two slots on the front side of the seat cushion 1, and the bottom surfaces of the two thigh supports 203 are both in contact with the top surface of the seat cushion 1. The hip support pad is divided into two forms according to the patient's usage posture. The first form is the supine posture form. First, the first pressing block 302 is pressed toward the side close to the thigh support 203. The first pressing block 302 drives the wedge-shaped strip 301 to slide horizontally. The second elastic member is forced to shrink. The wedge-shaped surface of the wedge-shaped strip 301 is squeezed against the outer wall of the horizontal axis on the adjacent first elastic limiting pin 304. The horizontal axis is forced to shrink and the first elastic limiting pin 304 is disengaged from the corresponding first limiting grooves of the limiting plate 306 after shrinkage. At the same time, the wedge strip 301 drives the protruding plate 504 to squeeze the outer wall of the horizontal plate 502, and the horizontal plate 502 is forced to drive the second pin 503 to move, and the fourth elastic member is forced to contract. After the second pin 503 moves, it disengages from the plug-in slot of the thigh support 203, and then lifts the rear part of the thigh support 203 upward. The thigh support 203 is forced to drive the corresponding connecting frame 202 to rotate through the guide column 501, and the connecting frame 202 drives the U-shaped frame 303 to rotate upward with the connection point of the corresponding limit plate 306 as the center of the circle. At the same time, according to the patient's thigh length, the thigh support 203 is pulled to the side away from the connecting frame 202, and the thigh support 203 drives the corresponding extension through the rotating rod 205 thereon. The rod 206 moves, and the two adjacent extension rods 206 jointly drive the corresponding elastic retractable belt 207 to move. After the thigh support 203 is moved to the appropriate position, the first pressing block 302 is no longer pressed, and the second elastic member is released and drives the wedge strip 301 to slide and reset through the first pressing block 302. The wedge surface of the wedge strip 301 no longer squeezes the outer wall of the transverse axis on the adjacent first elastic limiting pin 304. The first elastic limiting pin 304 is released to drive the transverse axis to slide and reset, and is stuck in several first limiting grooves of the corresponding limiting plate 306. The first elastic limiting pin 304 limits the adjacent connecting frame 202 through the U-shaped frame 303, and the connecting frame 202 is relatively fixed through two guide columns 501. The adjacent thigh support 203 is limited, and the thigh support 203 is restricted to remain in an inclined state. When the wedge strip 301 is reset, it drives the protruding plate 504 to slide and reset. The protruding plate 504 no longer presses the outer wall of the cross plate 502. The fourth elastic member is released and drives the second pin 503 to move and reset through the cross plate 502. After the second pin 503 is reset, it is inserted into the plug-in slot of the thigh support 203, thereby limiting the thigh support 203 and maintaining a distance between the thigh support 203 and the adjacent connecting frame 202. Through the above steps, the position of the thigh support 203 can be adjusted according to the patient's thigh length, so that the patient's thigh is more comfortable when placed on the thigh support 203.

[0031] Then, the second pressing block 401 is pressed, and the second pressing block 401 is forced to drive the sliding frame 403 to slide through the first sliding shaft 402, and the third elastic member is forced to shrink, and the sliding frame 403 squeezes the outer wall of the convex shaft of the first latch 404 through the first inclined groove therein, and the convex shaft is forced to drive the first latch 404 to slide to the side away from the rotating column 305, and the first latch 404 slides and disengages from the second limiting groove of the rotating column 305. At the same time, the sliding frame 403 squeezes the outer wall of the second sliding shaft 406 through the second inclined groove therein, so that the two adjacent limiting blocks 405 slide close to each other, and the sliding The bracket 403 drives the corresponding wedge-shaped rod 602 to slide horizontally. After the wedge-shaped rod 602 slides, it squeezes the inclined surface of the wedge-shaped groove of the second elastic limiting pin 601. The second elastic limiting pin 601 shrinks and slides under the force. After the second elastic limiting pin 601 slides, it disengages from the third limiting groove on the front side of the seat cushion 1. Then the thigh bracket 203 rotates with the connection between the rotating column 305 and the plug-in bracket 201 as the center of the circle. The thigh bracket 203 drives the corresponding connecting bracket 202 to rotate through the two guide columns 501. The connecting bracket 202 drives the rotating column 305 to rotate through the U-shaped bracket 303 and the limiting plate 306. At this time, the two The thigh brackets 203 rotate away from each other. When the thigh brackets 203 rotate to a suitable angle, they no longer press the second pressing block 401. The third elastic member is released and drives the first sliding shaft 402 to slide back to its original position through the second pressing block 401. The first sliding shaft 402 drives the sliding frame 403 to slide back to its original position. The sliding frame 403 squeezes the outer wall of the convex shaft of the first latch 404 through the first inclined groove therein. The convex shaft is forced to drive the first latch 404 to slide back to its original position. After the first latch 404 is reset, it is inserted into the second limiting groove of the rotating column 305 to limit the rotating column 305, so that the rotating column 305 no longer The second elastic limit pin 601 is released to slide and reset, and the second elastic limit pin 601 is inserted into the third limit slot on the front side of the seat cushion 1 after being reset, so that the two thighs of the patient can be placed on the two thigh supports 203 respectively, and the two thighs can be opened outward to form a lithotomy position.

[0032] The two adjacent extension rods 206 are then lifted up at the same time, and the extension rods 206 are forced to drive the corresponding rotating rods 205 to rotate upward with the connection point of the thigh support 203 as the center of the circle, and the rotating rods 205 respectively drive the corresponding ratchet 702 to rotate, and the ratchet 702 continuously rotates with the connection point of the through hole of the rotating rod 205 as the center of the circle under the action of the corresponding ratchet 701, and the two adjacent extension rods 206 jointly drive the corresponding elastic expansion belt 207 to move. When the rotating rod 205 is rotated to a suitable angle, the extension rod 206 is released, the ratchet 702 is stuck in the ratchet 701, and the ratchet 702 limits the extension rod 206 through the rotating rod 205, and the two adjacent extension rods 206 jointly drive the corresponding elastic expansion belt 207 to stop moving. At this time, the breech support pad is deformed into a supine posture, and the patient lies on his back on the breech support pad, with the patient's two thighs placed on the two thigh supports 203 respectively, and the two calves placed on the two elastic expansion belts 207 respectively, so as to facilitate the doctor to examine or treat the patient's perineum or other parts.

[0033] The second form of the hip support pad is the side-lying posture form. When the hip support pad needs to be deformed from the supine posture form to the side-lying posture form, first press the second pressing block 401, so that the two limiting blocks 405 are respectively disengaged from the slots on the front side of the seat cushion 1, and the second elastic limiting pin 601 is disengaged from the third limiting slot of the seat cushion 1. At this time, the plug-in frame 201 can be moved, and the plug-in frame 201 is pulled out from the slot of the seat cushion 1, and then one of the thigh supports 203 is placed aside, and then the plug-in frame 201 corresponding to the other thigh support 203 is inserted into one of the seat cushions 1. The patient's thigh position is adjusted according to the patient's thigh position, and the above steps are repeated to rotate the rotating column 305 with the connection of the plug-in frame 201 as the center, so as to adjust the angle of the thigh support 203. Then, the second pressing block 401 is no longer pressed, so that the two limiting blocks 405 and the second elastic limiting pin 601 are reset. After the limiting block 405 is reset, it is inserted into the long groove 603 of the seat cushion 1. After the second elastic limiting pin 601 is reset, it is inserted into the fourth limiting groove, so as to limit the plug-in frame 201. Then, the first pressing block 401 is pressed. The block 302 is pressed toward the side close to the thigh support 203, and the above steps are repeated to adjust the angle of the thigh support 203, and then the first pressing block 302 is released, and then the limiting plate 801 close to the rear side of the seat cushion 1 is pulled toward the side away from the thigh support 203, the fifth elastic member is extended by the force, and the limiting plate 801 drives the third latch 802 to disengage from the fifth limiting groove of the corresponding extension rod 206. The extension rod 206 can move after being freed from the restriction, and then the extension rod 206 close to the front side of the seat cushion 1 is rotated with the connection point of the corresponding rotating rod 205 as the center of the circle, and the extension rod 206 close to the front side of the seat cushion 1 is rotated. The extension rod 206 on the side applies a pulling force to the extension rod 206 adjacent to the rear side through the elastic telescopic belt 207, and the extension rod 206 is subjected to the force and rotates with the connection point of the corresponding rotating rod 205 as the center of the circle. As the extension rod 206 rotates, the telescopic end of the extension rod 206 close to the rear side of the seat cushion 1 gradually extends, and then the limit plate 801 is released, and the fifth elastic member contracts to drive the limit plate 801 to reset, and the limit plate 801 drives the corresponding third latch 802 to reset. After the third latch 802 is reset, it is inserted into the fifth limit groove of the corresponding extension rod 206, thereby limiting the extension rod 206. Fig.13 As shown, the calf support mechanism and the thigh support mechanism at this time form a V shape, which is more ergonomic. When the patient lies on his side, the upper thigh and calf can be placed on the thigh support 203 and the elastic band 207. The above steps can make the patient more comfortable when lying on his side.

[0034] Initially, the first elastic wedge block 901 is inserted into the first slot of the arc pad 204, and the arc pad 204 is restricted and cannot move. When the hip support pad is deformed into a supine posture, the arc surface of the arc pad 204 just fits with the patient's popliteal fossa. The arc pad 204 fits with the patient's popliteal fossa and can provide more comfortable support for the patient's legs. When the hip support pad is deformed into a side-lying posture, the first elastic wedge block 901 is pushed to the side away from the arc pad 204. The first elastic wedge block 901 is forced to shrink and slide, and disengage from the first slot of the arc pad 204. At this time, the arc pad 204 can move, and the arc pad The plate 204 is pressed forward, and the first elastic member is forced to shrink. Then the arc pad 204 contacts and squeezes the wedge surface of the second elastic wedge block 1001. The second elastic wedge block 1001 shrinks and slides under the force until the second groove of the arc pad 204 is aligned with the second elastic wedge block 1001. The second elastic wedge block 1001 releases the sliding reset and is stuck in the second groove of the arc pad 204, thereby limiting the arc pad 204. The first elastic member remains in a contracted state. By adjusting the position of the arc pad 204, the leg comfort of the patient when lying on his side can be improved. Lying on his side can make it easier for doctors to perform enema and other treatments on the patient.

[0035] After the treatment of the patient is completed, the limiting plate 801 close to the rear side of the seat cushion 1 is first pulled to the side away from the thigh support 203, so that the third pin 802 is disengaged from the fifth limiting groove of the corresponding extension rod 206, and the telescopic end of the extension rod 206 is retracted and reset, and then the limiting plate 801 is loosened, so that the third pin 802 is inserted into the fifth limiting groove of the extension rod 206 to limit the extension rod 206, and then the breaking block 703 is twisted to make the breaking block 703 drive the pawl 702 to disengage from the ratchet 701. After the pawl 702 is disengaged from the restriction, the rotating rod 205 can move, and the staff drives the rotating rod 205 to rotate and reset through the extension rod 206, and then twists the breaking block 703 to reset it, so that the pawl 702 is meshed with the ratchet 701 again, and then presses the second pressing block 401, so that both limiting blocks 405 are disengaged from the long groove 603, and the second elastic limiting pin 601 is separated from the seat cushion. 1, at this time, the plug-in frame 201 can move, pull the plug-in frame 201 out of the long slot 603, and insert the two plug-in frames 201 into the two slots of the seat cushion 1 respectively, rotate the thigh bracket 203, so that the rotating column 305 rotates and resets with the connection of the plug-in frame 201 as the center, release the second pressing block 401, and then reset the limiting block 405 and the second elastic limiting pin 601, and then press the first pressing block 302, so that the first elastic limiting pin 304 is disengaged from the first limiting slot of the limiting plate 306, and the second latch 503 is disengaged from the plug-in slot of the thigh bracket 203, slide the thigh bracket 203 to the side close to the connecting frame 202 and reset it, and rotate the U-shaped frame 303 with the connection of the limiting plate 306 as the center, release the first pressing block 302, and then reset the first elastic limiting pin 304 and the second latch 503, thereby completing the reset work of the hip support pad.
