Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a lithotomy leg support with heating and massage functions. Background Technology

[0002] Patent application CN202122870266.X discloses a massage chair leg support structure, including an upper leg support, a lower leg support, and a drive assembly. The upper and lower leg supports are slidably connected. The drive assembly is used to drive the upper and lower leg supports to slide relative to each other. The drive assembly includes a retractable drive rod and a power component for driving the drive rod to extend and retract. One end of the drive rod is connected to the upper leg support, and the other end of the drive rod is relatively movable to the lower leg support. The leg support structure also includes a safety switch, which is installed on the lower leg support and connected to the power component. When the upper and lower leg supports are subjected to force, causing the other end of the drive rod to move relative to the lower leg support and triggering the safety switch, the power component stops driving the drive rod to extend and retract. However, the disadvantage of this technical solution is that it cannot adapt to the leg structures of different patients. Utility Model Content

[0034] Example 1

[0035] like Figure 1-12As shown, a lithotomy leg support with heating and massage functions includes a leg support connecting tube 1, a leg support extension connecting tube 2, a rotating sleeve 3, an adjusting handle 4, a connecting rod 5, an air cushion 1 6, an air cushion 2 7, a positioning rod 1 13, a positioning rod push spring 14, a positioning slot 1 15, a matching slide rod 16, a limiting sleeve 17, a positioning rod 2 18, a positioning rod push spring 2 19, and a positioning slot 21. A matching slide rod 16 is slidably mounted on the leg support connecting tube 1, and the matching slide rod 16 is fixedly mounted on the leg support extension connecting tube 2. A limiting sleeve 17 is installed on the leg support connecting tube 1 to limit the sliding movement of the matching slide rod 16. Multiple positioning slots 21 are provided on the leg support connecting tube 1. Two positioning rods 18 are slidably mounted on the matching slide rod 16. A positioning spring 19 is provided between the two locking rods 18. The positioning locking rods 18 are connected to the positioning slots 21. An adjusting handle 4 is fixedly installed on the leg support tube 1. A rotating sleeve 3 is rotatably installed on the adjusting handle 4. The rotating sleeve 3 has a positioning slot 15, and multiple positioning slots 15 are provided. A positioning rod 13 is slidably installed on the adjusting handle 4, and two positioning rods 13 are provided. A positioning spring 14 is provided between the two positioning rods 13. The positioning rod 13 is connected to the positioning slots 15. Both the leg support tube 1 and the leg support extension tube 2 are equipped with airbag binding components. With this configuration, the distance between the leg support tube 1 and the leg support extension tube 2 changes relative to the sliding leg support tube 1 and the sliding rod 16, thereby facilitating adaptation to the leg structures of different patients.

[0036] Example 2

[0037] like Figure 1-12 As shown, both the leg support connecting tube 1 and the leg support extension connecting tube 2 are equipped with heating devices. The heating devices are of model MHISC-4 and are set at around 40°C, which can effectively prevent heat loss during surgery, improve patient comfort, and reduce the incidence of adverse events.

[0038] Example 3

[0039] like Figure 1-12As shown, the airbag strapping assembly includes an airbag 8, a contact sleeve 9, a contact post 10, a locking nut 11, a mating opening 12, and an air pump 20. One end of the airbag 8 is fitted with the contact sleeve 9, and the other end is fitted with the contact post 10. The contact sleeve 9 has a mating opening 12, which slides into the contact post 10 and is locked by the locking nut 11. The air pump 20 is mounted on the airbag 8 and is controlled by a microcontroller. The airbag 8 is attached to the leg support connecting tube 1 or the leg support extension connecting tube 2. With this setup, the patient is in the lithotomy position, with both lower limbs placed on the leg support connecting tube 1 or the leg support extension connecting tube 2. The angle between the patient's popliteal fossa, lower leg, and the leg support connecting tube 1 or the leg support extension connecting tube 2 is adjusted. After positioning the lower limbs, the airbag 8 on the leg support connecting tube 1 or the leg support extension connecting tube 2 covers the patient's lower limbs, and the airbag 8 is strapped to the patient's legs, ensuring that the contact post 10 and the mating opening 12 are properly engaged. The opening 12 is appropriately fitted, and the locking nut 11 is tightened to fix the patient's leg. Then, the air pump 20 is controlled by the 8255 microcontroller to inflate the airbag 8. The air pump 20 is controlled by the 8255 microcontroller to perform intermittent inflation-deflation cycles on the airbag 8, such as inflation for 10 seconds and deflation for 50 seconds. The air cushion 1 6 and air cushion 2 7 are set with pressure gradients, and are inflated sequentially from the distal ankle to the proximal thigh to form gradient pressure, such as 45→35→30 mmHg. This simulates the action of a muscle pump, which pushes blood and lymph fluid back towards the heart, promotes blood return in the lower limbs, and reduces the risk of deep vein thrombosis in the patient's lower limbs. The intermittent inflation-deflation cycle of the airbag 8 controlled by the air pump 20 by the 8255 microcontroller can evenly and stably stimulate the patient's lower limb muscles, reduce tissue ischemia, numbness, and pressure damage caused by prolonged fixed position, and is especially suitable for patients undergoing long-term surgery.
