[0021] The following will be combined with the drawings Figure 1 - the drawings Figure 3This invention further illustrates the specific implementation of an adjustable cylindrical positioning pad used in knee arthroscopy. It overcomes the shortcomings of existing positioning pads, which often have a simple overall structure, mostly just a simple cylindrical filling material. While such pads offer moderate softness, they lack strength and can easily cause limb movement during use. Furthermore, the length of existing pads is not adjustable, making them unsuitable for heavier patients. This new positioning pad features an internal skeleton, not entirely filled material, with a filling space between the outer layer of the pad and the skeleton. Within this space, memory foam and gel are sequentially filled from the inside out, forming a memory foam layer and a gel layer. This allows the device to maintain softness while possessing a certain degree of stability and strength, thus enhancing patient comfort. The adjustable cylindrical positioning pad used in knee arthroscopy is not limited to the description in the following embodiments.

[0022] Example 1:

[0023] This embodiment provides an adjustable cylindrical positioning pad for use in knee arthroscopy, such as... Figures 1-3 As shown, the device includes a positioning pad body 1 and a frame 3. The positioning pad body 1 adopts a cylindrical structure with both ends arched outwards, ensuring that the surgeon's knee joint is positioned between the two arched positions during use. This prevents the surgeon's limb from sliding to the sides, improving safety during surgery. The frame 3 is located inside the positioning pad body 1 to enhance the stability of the entire positioning pad. The frame 3 can be adjusted in length under external constraints. A filling space 10 is left between the outer layer of the positioning pad body 1 and the frame 3. The filling space 10 is filled with memory foam and fruit foam from the inside out. The gel forms a memory foam layer 100 and a jelly gel layer 101. This structural design makes the device more flexible overall, making it more comfortable for the surgeon to use. The outward ridges at both ends of the positioning pad body 1 prevent the surgeon's limbs from sliding to the sides, ensuring that the limbs will not slip off the operating table and improving the safety of the surgery. The skeleton 3 is extendable, so for some heavy surgeons, the effective application length of the positioning pad body 1 can be adjusted according to actual needs, making it more suitable for the surgeon and more comfortable to use.

[0024] Specifically, such as Figure 3As shown, in order to realize the length adjustment of the skeleton 3, in the embodiment, the two ends of the skeleton 3 are provided with height adjustment parts 31, and a connecting stud 310 is mounted at one end of the height adjustment part 31 connected with the skeleton 3. An installation screw hole 300 adapted to the connecting stud 310 is formed at the end of the skeleton 3, and the connecting stud 310 is inserted into the installation screw hole 300. Such a structure allows the height adjustment part 31 to move outward or inward under the action of the thread when the height adjustment part 31 is rotated, thereby achieving the effect of adjusting the effective length of the skeleton 3.

[0025] It should be noted that, relative to the diameter of the connecting stud 310, the wall thickness of the skeleton 3 at the position of the installation screw hole 300 is negligible. Therefore, when the connecting stud 310 moves outward, the exposed part of the connecting stud 310 will not have fillers entering, and thus will not be clamped by the fillers.

[0026] Specifically, as shown in Figures 2-3 in order to make the limbs of the operator more comfortable when contacting the arched position at both ends of the body position pad main body 1, in the embodiment, the surface of the height adjustment part 31 adopts a smooth streamline structure that arches outward, so that the operator is more comfortable when contacting.

[0027] Specifically, as shown in Figure 2 in order to improve the elasticity and rebound effect of the entire body position pad and ensure that the skeleton 3 does not easily rotate when the height adjustment part 31 is rotated, in the embodiment, a plurality of elastic components 30 are arranged in a ring array on the surface of the skeleton 3. The elastic component 30 adopts a spring, and the elastic component 30 extends at least to the middle position of the memory foam layer 100. This can greatly improve the elasticity and rebound effect of the entire body position pad. Since the elastic component 30 extends into the memory foam layer 100, the skeleton 3 has high consistency with the fillers. Therefore, when the height adjustment part 31 is rotated, the skeleton 3 is not easy to rotate.

[0028] Specifically, as shown in Figures 2-3 in order to ensure that the length of the skeleton 3 can be adjusted, in the embodiment, a cloth cover 102 is sleeved outside the body position pad main body 1, and the two ends of the cloth cover 102 adopt an open structure. This can facilitate the opening of the cloth cover 102, and the rotation of the height adjustment part 31 at the end of the skeleton 3, thereby achieving the effect of conveniently adjusting the effective length of the skeleton 3.

[0029] Specifically, as shown in Figures 1-3 in order to avoid the skeleton 3 and the fillers from coming out, in the embodiment, the open structure at both ends of the cloth cover 102 is fixed by a belt 2, and one end of the belt 2 extends outward. The extended part is used to fix the body position pad main body 1 on both sides of the operating bed, so that the position of the body position pad main body 1 is fixed and will not slide during use.

[0030] Specifically, the arch part length of the body position pad body 1 is 170±10mm, the maximum diameter of the arch part is 140±10mm, and the extension length of the belt 2 is 500±30mm.

[0031] It should be noted that the above filling is memory sponge and jelly gel.

[0032] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
