Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, specifically to a prone ankle support pad. Background Technology

[0002] In interventional surgery, especially in procedures such as percutaneous vertebroplasty for fractures of the lumbar and thoracic vertebrae, patients usually need to maintain a strict prone position for a long time to ensure the exposure of the surgical field and the accuracy of intraoperative imaging monitoring. In this position, the patient's feet and ankles are often under special stress: the toes need to be pressed against the end of the operating table to provide partial support and stability for the lower limbs, while the ankle and heel are therefore suspended in the air. Although this posture helps to maintain postural stability, maintaining it for a long time will cause significant problems: on the one hand, the toes are subjected to a lot of pressure locally, which can easily cause patients to experience strong soreness, numbness and other discomfort during the operation. For patients with poor peripheral circulation such as diabetes and peripheral vascular disease, there is a higher risk of inducing local pressure sores and impairing skin integrity. On the other hand, existing foot and ankle support devices generally have the defects of a single support surface slope and non-adjustable height. They cannot effectively distribute pressure on the toes and provide sufficient and ergonomic comfort support for the suspended ankle while meeting the functional requirement of maintaining a specific angle of the ankle joint during surgery. In other words, they cannot achieve the ideal tilt of the support surface that is higher in the front and lower in the back to transfer pressure from the toes to the arch / heel and lift the ankle. Moreover, they cannot support the patient's knee and leg areas according to the patient's needs. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a prone ankle support pad, which effectively solves the problem of inconvenient lower limb support for patients during supine surgery.

[0004] The technical solution is as follows: This utility model includes a support block in the left and right direction. The support block has grooves on the left and right sides with upward openings and through the front and back. An arc-shaped support airbag is provided in the groove. The support airbag is inclined with the front higher and the back lower. A support plate with the same shape is provided on the lower side of the support airbag. A movable block that can slide up and down is provided at the lower end of the support plate. A placement groove is provided on the front side of the support block. An air cylinder with a left and right axis is rotatably connected in the placement groove. An airbag pad is wrapped around the outside of the air cylinder. The inside of the airbag pad is connected to the inside of the air cylinder through a connecting pipe. The free end of the airbag pad passes through the front side of the support block and is provided with a pull rod.

[0005] This invention utilizes an arc-shaped support airbag with a higher front and lower rear, combined with an adjustable movable block mechanism, to provide stable and height- and angle-adjustable support for the dangling ankles of prone patients. This effectively distributes pressure on the toes, reducing discomfort and the risk of pressure sores during prolonged surgery. The addition of a pull-out, inflatable airbag expands the support range, providing additional flexible cushioning support for the lower leg or knee area as needed, further improving lower limb comfort and preventing local pressure sores. The coordinated design of the inflation cylinder and rotating cylinder, along with the polygonal piston column structure, ensures the reliability and efficiency of the airbag inflation. The airbag can be wound and stored on the inflation cylinder, and rapid deflation and rewinding are achieved by rotating the inflation cylinder in conjunction with the support block compression. This design is convenient, space-saving, simple, innovative, and highly practical. Attached Figure Description

[0011] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 5 The support block 1 is provided, which includes a left-right support block 1. The left and right sides of the support block 1 are respectively provided with grooves 2 that are open upwards and pass through the front and back. The grooves 2 are provided with arc-shaped support airbags 3. The support airbags 3 are inclined in shape with the front higher and the back lower. The support plate 4 with the same shape is provided on the lower side of the support airbags 3. The lower end of the support plate 4 is provided with a movable block 5 that can slide up and down. The front side of the support block 1 is provided with a placement groove 6. The left-right axis inflation cylinder 7 is rotatably connected in the placement groove 6. The outer side of the inflation cylinder 7 is wrapped with an airbag pad 8. The inner side of the airbag pad 8 is connected to the inner side of the inflation cylinder 7 through a connecting pipe 9. The free end of the airbag pad 8 passes through the front side of the support block 1 and is provided with a pull rod 10.

[0013] In order to make the moving block 5 slide up and down, the support block 1 has an upward-facing sliding groove 11 on the left and right sides respectively. The moving block 5 is located in the sliding groove 11 and is slidably connected to the sliding groove 11.

[0014] To facilitate control of the movement of the moving block 5, the two moving blocks 5 are symmetrical from left to right. The right end face of the moving block 5 on the right side is an inclined surface that is lower on the left and higher on the right. Trapezoidal blocks 12 are slidably connected to the left and right ends of the support block 1, and the opposite surfaces of the two trapezoidal blocks 12 can contact the inclined surfaces of the moving blocks 5 on their corresponding sides.

[0015] To facilitate the movement of the trapezoidal block 12, the left and right ends of the support block 1 are respectively rotatably connected with screws 13, and the two screws 13 are threadedly connected to the trapezoidal block 12 on opposite sides.

[0016] To prevent the movable block 5 from coming out of the slide groove 11, two left and right opposite baffle grooves 14 are opened in the middle of the support block 1, and baffle blocks 15 are fixed at the opposite ends of the two movable blocks 5 respectively, and the baffle blocks 15 are inserted into the baffle grooves 14.

[0017] To facilitate inflation of the airbag cushion 8, the left end of the air cylinder 7 passes through the support block 1 and is slidably connected to the inner side of the support block 1. The projection of the inner side of the air cylinder 7 in the left and right directions is polygonal. The piston column 16 fits against the inner side of the air cylinder 7 and is fixed with a pull handle at the left end.

[0018] To facilitate control of gas intake and exhaust, the right end of the air cylinder 7 passes through the support block 1 and is threadedly connected to a rotating cylinder 17. An air vent 18 is fixed inside the rotating cylinder 17. The left end of the air vent 18 is connected to the inside of the air cylinder 7 and the right end is connected to the outside. An air intake one-way valve 19 with its opening facing left is provided inside the connecting pipe 9.

[0019] When using this utility model, after the patient has assumed a prone position as required, with the lower limbs properly positioned and the toes pressing against the end of the operating table so that the ankles are suspended in the air, the medical staff first place this device at a suitable position at the end of the bed in front of the patient's feet, with the patient's insteps in contact with the support airbag 3. Then, according to the patient's foot size, the required ankle joint angle during the operation, and comfort requirements, the height of the supports on both sides is adjusted simultaneously: by rotating the screws 13 at both ends of the support block 1, the outer trapezoidal block 12 is driven to move inward. Since the inclined surface of the trapezoidal block 12 contacts the moving block 5, the movement of the trapezoidal block 12 will force the moving blocks 5 on the left and right sides to slide upward along the retaining groove 14 in their respective sliding grooves 11. The moving block 5 drives the support plate 4 and the support airbag 3 on it to rise, thereby changing the overall height of the support airbag 3 and providing stable and compliant support force for the patient's suspended ankle. If it is necessary to support the patient's lower limbs or knees to prevent pressure sores, simply pull the lever 10 forward to pull the airbag cushion 8 out of the placement slot 6 and lay it flat on the operating table. Then, the medical staff holds the handle at the left end of the air cylinder 7 and pulls the piston column 16 on its inner side back and forth. Because the inner cavity of the air cylinder 7 is polygonal, the piston column 16 slides against it to ensure airtightness. External air is drawn into the air cylinder 7 and, under the action of the air inlet one-way valve 19, the gas is pushed into the airbag cushion 8 through the ventilation tube 18 and the connecting tube 9. Pushing the piston rod 16 will force gas into the airbag pad 8 to inflate it. After the airbag pad 8 is inflated to an appropriate level, it forms the final flexible cushioning support surface. The patient's ankles and legs can be comfortably placed on the support airbag 3 and the inflated airbag pad 8, effectively dispersing the pressure on the toes and supporting the suspended parts. When deflating the airbag pad 8, simply rotate the rotating cylinder 17 to disengage it from the inflation cylinder 7, and also disengage the vent tube from the inflation cylinder 7. At this time, the gas in the inflation cylinder 7 can be discharged. Then, rotate the handle to make the handle drive the inflation cylinder 7 to rotate, and the airbag pad 8 will rewind onto the inflation cylinder 7. During the winding process, the support block 1 contacts the airbag pad 8 and squeezes out the gas in the airbag pad 8, completing the deflation.

[0020] This invention utilizes an arc-shaped support airbag with a higher front and lower rear, combined with an adjustable movable block mechanism, to provide stable and height- and angle-adjustable support for the dangling ankles of prone patients. This effectively distributes pressure on the toes, reducing discomfort and the risk of pressure sores during prolonged surgery. The addition of a pull-out, inflatable airbag expands the support range, providing additional flexible cushioning support for the lower leg or knee area as needed, further improving lower limb comfort and preventing local pressure sores. The coordinated design of the inflation cylinder and rotating cylinder, along with the polygonal piston column structure, ensures the reliability and efficiency of the airbag inflation. The airbag can be wound and stored on the inflation cylinder, and rapid deflation and rewinding are achieved by rotating the inflation cylinder in conjunction with the support block compression. This design is convenient, space-saving, simple, innovative, and highly practical.
