Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a knee joint protection device for patients undergoing lithotomy. Background Technology

[0002] During surgeries requiring the lithotomy position, such as gynecological and urological procedures, patients typically need to elevate and separate their legs to facilitate surgical manipulation. However, in this position, the patient's knee joint is easily compressed by the surgeon, especially during prolonged surgeries, potentially leading to poor blood circulation, nerve damage, and even pressure sores. While some devices exist on the market to protect the patient's knee joint, most are simple in design, providing only basic support and lacking effective pressure distribution mechanisms. For example, simple sponge pads or soft cushions can alleviate some pressure, but they easily deform after prolonged use, losing their original protective effect. Furthermore, these devices are often not securely fixed and are prone to displacement during surgery, affecting surgical procedures. Therefore, we propose a knee joint protection device for patients undergoing lithotomy. Utility Model Content

[0003] The main purpose of this invention is to provide a knee joint protection device for patients undergoing lithotomy, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A knee joint protection device for patients undergoing lithotomy includes a support body, an anti-pressure protective cover fixedly connected to the upper middle part of the support body, fixing ropes at all four corners of the support body, and a removable memory foam pad detachably installed on the inner surface of the anti-pressure protective cover.

[0006] Preferably, the supporting body includes an arch-shaped supporting tube, and two arch-shaped supporting tubes are provided and symmetrically distributed from left to right. Two arc-shaped supporting ribs are fixedly connected between the two arch-shaped supporting tubes and the two arc-shaped supporting ribs are symmetrically distributed from front to back.

[0007] By adopting the above technical solution, a stable frame structure is formed, which can not only firmly support the patient's knee joint and ensure that it will not shift during the operation, but also effectively distribute pressure and reduce knee discomfort and damage caused by maintaining the lithotomy position for a long time.

[0008] Preferably, both the front and rear sides of the outer surface of the two arch-shaped support tubes are provided with connecting through holes, and the fixing rope is fixedly connected to the arch-shaped support tube through the connecting through holes.

[0009] By adopting the above technical solution, the stability of the device is further enhanced by using a fixed rope to securely mount the lithotomy leg support on the operating table, ensuring the safety and reliability of the surgical procedure.

[0010] Preferably, the pressure-resistant protective cover has a curved shape, and the curvature is the same as that of the arc-shaped support rib. The lower end of the pressure-resistant protective cover is fixedly connected to the arc-shaped support rib on the same side on both the front and rear sides, and the left and right ends of the arc-shaped support rib are fixedly connected to the arch-shaped support tube on the same side.

[0011] By adopting the above technical solution, the pressure-resistant protective cover can be tightly fixed to the supporting body, thereby enhancing the overall stability and structural strength of the device.

[0012] Preferably, the cross-section of the pressure-resistant protective cover is semi-tubular, and the thickness of the pressure-resistant protective cover is equal to the thickness of the arc-shaped support rib and the arch-shaped support tube.

[0013] By adopting the above technical solution, the curved shape of the pressure-resistant protective cover can perfectly fit the natural curvature of the patient's knee joint, ensuring comfort.

[0014] Preferably, the pressure-resistant protective cover is made of EVA foam material, and the arch-shaped support tube and the arc-shaped support rib are made of rigid PVC material.

[0015] By adopting the above technical solution: the pressure-resistant protective cover is made of EVA foam material, which has good cushioning performance and breathability, and can provide soft support to reduce the patient's pressure.

[0016] Preferably, the shape of the removable memory foam pad is adapted to the shape of the pressure-resistant protective cover. The outer surface of the removable memory foam pad is fixedly connected with a sub-hook and loop fastener, and the inner surface of the pressure-resistant protective cover is fixedly connected with a female hook and loop fastener that works with the sub-hook and loop fastener. The removable memory foam pad is fixedly connected to the inner surface of the support body through the sub-hook and loop fastener.

[0017] By adopting the above technical solution, a removable memory foam pad is fixed to the inner surface of the pressure-resistant protective cover with Velcro. It can gradually mold to the shape of the patient's knee joint, providing personalized support and pressure relief, which further improves the patient's comfort and protection. At the same time, the removable design of the memory foam pad makes cleaning and maintenance more convenient, reduces the risk of cross-infection, and extends the service life of the device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The main support consists of two symmetrical arched support tubes and two symmetrical arc-shaped support ribs. Both the arched support tubes and the arc-shaped support ribs are made of rigid PVC material, forming a stable frame structure. This design not only firmly supports the patient's knee joint, ensuring that it will not shift during the operation, but also effectively distributes pressure, reducing knee discomfort and damage caused by maintaining the lithotomy position for a long time. At the same time, the device can be securely mounted on the lithotomy leg support on the operating table using fixing ropes, further enhancing the stability of the device and ensuring the safety and reliability of the surgical procedure.

[0020] 2. The pressure-relief cover is made of EVA foam, which has excellent cushioning and breathability, providing soft support and reducing pressure on the patient. The curved shape of the cover perfectly conforms to the natural curvature of the patient's knee joint, ensuring comfort. Furthermore, a removable memory foam pad is secured to the inner surface of the cover with Velcro. This removable memory foam pad gradually molds to the shape of the patient's knee joint, providing personalized support and pressure relief, further improving patient comfort and protection. The removable design of the memory foam pad also makes cleaning and maintenance easier, reducing the risk of cross-infection and extending the device's lifespan. Attached Figure Description
