Description

Technical Field

[0001] The present application relates to the technical field of prosthetic manufacturing, and in particular to a prosthetic sensory restorer. Background Art

[0002] Wearing prosthetic limbs for the disabled is an important technology in modern rehabilitation medicine, which aims to help people who have lost limbs regain a certain degree of self-care ability and the ability to participate in social activities. This technology uses knowledge from multiple fields such as biomechanics, materials science, and electronic engineering to design and manufacture devices that can replace the functions of missing limbs. In order to ensure the best comfort and functional match, prosthetic limbs usually need to be customized according to the shape, length, skin condition, etc. of the individual's residual limb. This process may include steps such as plaster molding, 3D scanning, multiple fittings and adjustments. With the development of science and technology, modern prosthetic limbs are becoming more and more intelligent. For example, myoelectric prostheses can control the movement of prosthetic limbs by detecting weak electrical signals from the residual limb muscles, achieving limb movements that are closer to nature.

[0003] Although modern prosthetic technology has made significant progress in restoring basic limb functions, the lack of real tactile perception is always a key problem that needs to be solved for wearers. Traditional prosthetic designs mostly focus on the optimization of mechanical structure, lightweight and durability of materials, and intelligent motion control, while paying relatively little attention to tactile feedback mechanisms. This "feeling loss" not only affects the user's stable grasp of handheld objects, the execution of fine movements such as force control, but also limits their perception of the environment and the quality of interaction, thereby weakening the sense of reality and integration of the prosthesis as a part of the body to a certain extent. Utility Model Content

[0004] This device provides a prosthetic sensory restorer, and the specific implementation is as follows:

[0005] A prosthetic sensory restorer, comprising:

[0006] Several hydraulic tube groups are integrated into the prosthesis, each of which is in a closed shape, and its two ends are respectively set as an A-end balloon and a B-end balloon. Each A-end balloon is respectively embedded on the inner side of the palm of the prosthesis, and each B-end balloon is set at the human arm. The B-end balloon senses and triggers the human arm by pressing the A-end balloon with the palm.

[0007] Based on the above technical solution, the A-end balloon is installed at the end of the prosthesis, such as the fingertips and palms, and is made of wear-resistant elastic material to ensure that it can effectively deform and trigger the sensing mechanism when it touches an object; the B-end balloon serves as the feedback end, and is correspondingly arranged under or close to the skin area retained at the residual limb end. It is also made of biocompatible and soft materials and is designed to exert perceptible pressure on the skin when deformed; the two balloons are connected by a closed hydraulic tube group, and the inside is filled with hydraulic oil with low shrinkage ratio in a wide range of high temperature, harmless to the human body, hypoallergenic, insulating and other indicators to ensure that the pressure can be quickly and accurately transmitted to the B-end balloon when the A-end balloon is under pressure.

[0008] Preferably, a pressure regulating assembly is provided on the inner side of the arm portion of the prosthesis, and the pressure regulating assembly is respectively connected in series to the hydraulic pipe group.

[0009] Preferably, the pressure regulating components are arranged equidistantly along the inner circumference of the arm portion.

[0010] Preferably, the pressure regulating assembly includes a pressure regulating chamber, one end of which is threadedly connected with an adjusting screw through a threaded hole; a piston is slidably provided in the pressure regulating chamber along its length direction, and a spring is provided between the end of the adjusting screw extending into the pressure regulating chamber and the piston.

[0011] Preferably, the hydraulic pipe assembly is divided into a first capillary branch and a second capillary branch, and the piston divides the pressure regulating chamber into two independent parts, wherein the part without the adjusting screw is connected to the first capillary branch and the second capillary branch.

[0012] Based on the above technical solutions, users need to go through a personalized adaptation process to adjust the balloon position, tube length and pressure threshold to ensure the optimal feedback effect; by directly acting on the pressure changes on the retained skin of the residual limb, a more intuitive tactile experience is provided, which helps to improve the wearer's object recognition ability and operation precision; compared with neural interface technology, this solution does not require surgical implantation, reduces risks and costs, and is a system that does not require control circuits or power supply. It has a simple and effective structure and is more suitable for wide promotion.

[0013] Preferably, the other end of the first capillary branch is connected to the B-end balloon, and the other end of the second capillary branch is connected to the A-end balloon.

[0014] Preferably, the first capillary branches are positioned and installed between adjacent voltage regulating assemblies through a plurality of limiting and binding blocks, and the limiting and binding blocks are arranged in sequence along the length direction of the voltage regulating assemblies.

[0015] Based on the above technical solution, the limiting binding block installs the first capillary tube against the wall along the inner side of the arm of the prosthesis, avoiding messy wire harnesses.

[0016] Preferably, the pressure regulating chamber is made of a transparent material.

[0017] Preferably, the arm portion and the portion corresponding to the side of the pressure regulating chamber are set as a transparent section.

[0018] Based on the above technical solution, by providing a pressure regulating chamber and an arm portion made of a transparent material, the user can visually observe the stretching of the spring to identify whether the hydraulic pipe group is normal or not.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. The utility model provides an A-end balloon and a B-end balloon that are interconnected. When the prosthesis contacts an object, the A-balloon at the prosthesis is squeezed, and at the same time, the B-balloon at the remaining arm of the human body is deformed, so that the wearer's local skin feels pressed, thereby restoring the sense of touch;

[0021] 2. The utility model uses an embedded voltage regulating component to adjust the sensitivity and intensity of feedback according to user preferences or different application scenarios;

[0022] 3. The utility model has a simple structure. When the hydraulic pipe group is broken and the pressing feedback cannot be continued, the specific location information of the damaged hydraulic pipe group can be quickly determined by observing the elongation of the spring in the pressure regulating assembly.
