Description

Technical Field

[0001] This application relates to an adjustable femoral medial condyle exposure device, belonging to the field of medical auxiliary device technology. Background Technology

[0002] The medial femoral condyle is one of the most common sites for bone tumors. For the treatment of bone tumors, whether it is limb-sparing surgery or amputation, it is necessary to accurately expose the medial femoral condyle to ensure complete tumor resection, reduce recurrence rate, and improve patient survival rate.

[0003] Currently, in clinical practice, clamping tools are mostly used to expose the medial femoral condyle. Although this can ensure a clear and complete surgical field, this structure requires medical staff to apply force, which is not only time-consuming and laborious, but also can easily cause excessive local pressure due to prolonged fixation of a certain part of the patient's lower limb, thus causing discomfort to the patient. Utility Model Content

[0004] To address the aforementioned issues, this application proposes an adjustable medial femoral condyle exposure device. While ensuring a clear and complete surgical field, it is not only convenient and time-saving to operate, but also avoids excessive local pressure that could damage the skin and tissues, thus improving patient comfort.

[0005] This utility model provides the following technical solution:

[0006] An adjustable femoral medial condyle exposure device includes a pad and an air bladder. The air bladder is located on the lower side of the pad. An arc-shaped groove is provided on the top surface of the pad along its longitudinal direction. Straps are provided on both sides of the groove. An air tube is connected to the air bladder. A sealing plug is provided at the end of the air tube away from the air bladder.

[0007] The airbag has a triangular cross-section, and the height of the cross-section gradually decreases from the inside to the outside. The pad has a trapezoidal cross-section, and the connection surface between the pad and the airbag is compatible.

[0031] Reference Figure 1-4 This application describes an adjustable femoral medial condyle exposure device.

[0032] The adjustable medial femoral condyle exposure device according to this embodiment includes a pad and an air bladder 1. The air bladder 1 is located on the lower side of the pad, making it easy to inflate and deflate, while avoiding damage to the air bladder 1 from instruments, clothing, etc. during surgery, thus extending the service life of the air bladder 1. The top surface of the pad has an arc-shaped groove 2 along its longitudinal direction to conform to the curve of the human leg, improve patient comfort, and facilitate accurate exposure of the medial femoral condyle. Straps are provided on both sides of the groove 2 to fix the patient's leg to the pad, preventing it from moving during surgery, thereby improving the stability and safety of the surgery. An air tube 3 is connected to the air bladder 1, and a sealing plug 4 is provided at the end of the air tube 3 away from the air bladder 1. The height of the device can be adjusted by inflating or deflating the air bladder 1, thereby adjusting the external rotation angle of the knee joint, providing the surgeon with a complete surgical field of vision, and can adapt to different patient body types (such as weight, height, etc.), improving the flexibility of the device.

[0033] The cross-section of the airbag 1 is triangular, and the height of the cross-section gradually decreases from the inside to the outside. This allows the airbag 1 to provide good support for the patient's leg after inflation, better expose the medial femoral condyle, facilitate the doctor's operation, and help improve the success rate of the surgery. The cross-section of the pad is trapezoidal, and the connection surface between the pad and the airbag 1 is adapted to ensure a tight connection between the two, which improves the stability and reliability of the device.

[0034] In the embodiments of this utility model, the material of the sealing plug 4 is not limited and can be selected according to actual needs. For example, the material of the sealing plug 4 is silicone.

[0035] In one embodiment, the padding includes a thigh fixation pad 5 and a calf fixation pad 6. The longitudinal axes of the thigh fixation pad 5 and the calf fixation pad 6 form an angle of 10-20 degrees, preferably 15 degrees, so as to better expose the medial femoral condyle during surgery via the distal femur, proximal tibia, and medial knee approach. This provides the surgeon with a clear field of vision, facilitates surgical operations, and conforms to ergonomic principles, reducing patient discomfort during the surgical process.

[0036] As one implementation method, the straps include a thigh strap 7 and a calf strap 8. The thigh strap 7 is located at the end of the thigh fixation pad 5 away from the calf fixation pad 6, and the calf strap 8 is located at the end of the calf fixation pad 6 away from the thigh fixation pad 5. The straps are used to fix different parts separately to avoid excessive local pressure that could damage the skin and tissues. This ensures the fixation effect while improving the patient's comfort.

[0037] As one implementation, both the thigh strap 7 and the calf strap 8 are equipped with Velcro, which has excellent softness, abrasion resistance and tear resistance, and can not only provide a reliable fixation effect, but also make it easy to adjust the tightness of the straps.

[0038] In one embodiment, both the thigh strap 7 and the calf strap 8 include a first strap 9 and a second strap 10. The Velcro includes a hook side 11 and a rough side 12. The first strap 9 is provided with the hook side 11, and the second strap 10 is provided with the rough side 12. The hook side 11 and the rough side 12 are bonded together, which makes the operation convenient and the fixation reliable, thereby reducing the surgical risk.

[0039] As one implementation method, the groove 2 is provided with a first anti-slip texture 13, which can significantly increase the friction between the lower limb and the groove 2, effectively prevent it from sliding or shifting in the groove 2, and improve the safety of the operation.

[0040] As one implementation method, the side of the airbag 1 away from the pad is provided with a second anti-slip texture 14, which can prevent the device from moving at will and provide better fixation and support for the patient's lower limbs.

[0041] As one implementation method, both the thigh fixation pad 5 and the calf fixation pad 6 are made of silicone gel, which can be sterilized and X-ray transparent, effectively disperses pressure, is not prone to forming pressure sores, and can protect the common peroneal nerve.

[0042] The working principle of the adjustable medial femoral condyle exposure device according to this embodiment is as follows:

[0043] The patient's thigh and lower leg are placed on the thigh fixation pad 5 and the lower leg fixation pad 6 respectively, and in contact with the first anti-slip texture 13 in the groove 2. Then, the hook surface 11 on the first strap 9 is bonded to the rough surface 12 on the second strap 10, so that the thigh strap 7 and the lower leg strap 8 fix the thigh and lower leg respectively. Finally, the sealing plug 4 is opened, and air is inflated into the air bag 1 through the trachea 3, so that the medial femoral condyle is exposed so that the surgeon can perform the surgical operation.

[0044] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0045] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
