TECHNICAL FIELD

[0001] The utility model relates to a prosthesis inner bush technical field especially relates to a kind of silicon rubber prosthesis inner bush. BACKGROUND

[0002] Prostheses are used to replace the function of missing limbs and, if necessary, to replace the visual effect of missing limbs, and are fixed to the body of a patient. Numerous possibilities are known for fixing a prosthesis. Widely used possibilities for fixing a prosthesis on a limb consist in being mounted on the remaining part of the limb, the so-called residual limb. The residual limb is wrapped in a generally shape-stable prosthesis sleeve. An introduction opening is formed on the proximal end of the sleeve, and at least one fastening device is provided on the distal end of the sleeve, on which further prosthesis components, such as joints or functional units, such as a prosthesis foot or a prosthesis hand, can be arranged. In order to achieve a good fit, a residual limb model is produced and the sleeve is matched to the contour of the residual limb model. In order to be able to compensate for volume fluctuations, it can be provided that the sleeve is produced narrower than the modelled residual limb.

[0003] In order to improve the wearing comfort, it can be provided that a so-called prosthesis liner is arranged between the prosthesis sleeve and the residual limb. The prosthesis liner generally consists of a closed base body with a proximal opening, which is worn on the residual limb like a stocking. An elastic material adheres to the surface of the residual limb and forms a connection between the residual limb and the prosthesis sleeve.

[0004] The existing prosthesis inner bush outer side does not have protection structure, is vulnerable to damage, and the material used cannot meet the use demand. For this purpose, a silicon rubber prosthesis inner bush is provided. SUMMARY

[0005] In view of the defects in the prior art, the technical problem solved by the utility model is that the existing prosthesis inner bush outer side does not have protection structure, is vulnerable to damage, and the material used cannot meet the use demand, and a silicon rubber prosthesis inner bush is provided.

[0006] To achieve the above purpose, the utility model provides:

[0007] A silicon rubber prosthesis inner bush, comprising a prosthesis inner bush main body, the prosthesis inner bush main body is of silicon rubber material, the bottom end inner wall of the prosthesis inner bush main body is provided with a circular arc surface, a textile sleeve is sleeved on the outer side of the prosthesis inner bush main body for protecting the prosthesis inner bush main body.

[0008] Preferably, a plurality of air holes for ventilation are formed in the bottom of the prosthesis inner bush main body.

[0009] Preferably, an internal thread cylinder is arranged at the bottom of the prosthesis inner bush main body for connecting a bolt to support walking.

[0010] Preferably, the textile sleeve is made of textile fabric and has a through hole at the bottom. The through hole is fitted on the outside of the internal threaded cylinder and does not affect the use of the internal threaded cylinder.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This utility model features a textile cover that protects the prosthesis's inner liner body from scratches. The inner liner body is made of silicone rubber, making it soft and comfortable to use. Multiple ventilation holes at the bottom of the inner liner body allow for airflow, preventing overheating inside. It offers good performance and meets user needs. Attached Figure Description

[0019] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] See Figures 1-4 As shown, a silicone rubber prosthesis liner includes a prosthesis liner body 2, which is made of silicone rubber. The inner wall of the bottom end of the prosthesis liner body 2 is provided with an arc surface 23. A textile sleeve 1 is provided on the outer side of the prosthesis liner body 2 for protecting the prosthesis liner body 2.

[0021] In this embodiment, the bottom of the prosthesis inner liner body 2 is provided with a plurality of ventilation holes 21 for ventilation, which have the functions of ventilation and perspiration.

[0022] In this embodiment, the bottom of the prosthesis inner sleeve body 2 is provided with an internally threaded cylinder 22 for connecting a bolt for walking support.

[0023] In this embodiment, the textile sleeve 1 is made of textile fabric, and the bottom is provided with a through hole 11, which is sleeved outside the internally threaded cylinder 22 and does not affect the use of the internally threaded cylinder 22. Since the silicone itself has good tensile properties and can be stretched more than twice, the silicone has an outer textile sleeve 1, which is a square matrix, and plays a protective role in limiting the stretching of the silicone.

[0024] In this embodiment, referring to Figure 5 、 Figure 6 、 Figure 7 , three kinds of outer shapes of the textile sleeve 1, any one of the three kinds of textile sleeves 1 can be used.

[0025] The working mode is that the textile sleeve 1 is wrapped around the prosthesis inner sleeve body 2 to protect the prosthesis inner sleeve body 2 from scratching, and the prosthesis inner sleeve body 2 is made of silicone rubber material, which is soft and comfortable to use. The bottom of the prosthesis inner sleeve body 2 is provided with a plurality of air holes 21 for ventilation, which can communicate the prosthesis inner sleeve body 2 with the outside air to avoid the prosthesis inner sleeve body 2 from being hot inside.

[0026] The utility model is not only limited to the above-mentioned best implementation, anyone can draw other various forms of products under the inspiration of the utility model, but no matter makes any change in its shape or structure, if it has the same or similar technical scheme with the utility model, it is within the protection scope.
