Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary equipment, and particularly relates to a prosthetic limb receiving cavity trial wearing and molding device. Background Art

[0002] A prosthesis is an artificial device specifically designed for amputees or those with incomplete limb loss. Its primary function is to replace some of the functions of the missing limb, allowing the patient to regain a certain level of independence and work ability. For lower limb prostheses, a socket must be tailored to the patient's residual limb to facilitate easy fitting. During the socket fabrication process, a workbench is required to assist the patient in taking the shape and fitting the prosthesis.

[0003] During the specific use of the above-mentioned workbench, we found that the movable kit is not actually needed to support the socket during the molding and fitting process. It is only needed before and after the molding and fitting operations to support the socket. However, although the movable kit on the existing prosthesis molding workbench can slide up and down on the support rod, because the support rod is fixed in one position, when the movable kit is no longer needed to support the socket or plaster mold, the support rod and the movable kit cannot be removed, which interferes with and obstructs the prosthetist's operation. Therefore, the existing prosthesis molding workbench still has the disadvantage of being inconvenient to use. Utility Model Content

DETAILED DESCRIPTION

[0050] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0051] Example 1:

[0052] like Figures 1-4 As shown, the prosthetic socket fitting and molding device provided in this embodiment includes a platform 1, a support portion 2 and a connecting sleeve 3, wherein:

[0053] The platform 1 is provided with a standing position for the patient to stand. The support part 2 is movably connected to the platform along the outer edge of the platform 1, and the support part 2 extends vertically. The connecting sleeve 3 is connected to the support part 2. The connecting sleeve 3 is used to install the prosthetic receiving cavity. Specifically, when the support part 2 rotates, the support part 2 drives the above-mentioned connecting sleeve 3 to move around the above-mentioned standing position.

[0054] Through the above structure, the support part 2 and the connecting sleeve 3 are no longer fixed in only one position. During specific use, the patient stands on the standing position of the platform 1. When not trying on or taking the shape, the connecting sleeve 3 is needed to support the receiving cavity. Therefore, the support part 2 and the connecting sleeve 3 thereon are moved to the side of the patient's residual limb, and the receiving cavity is installed on the connecting sleeve 3. When trying on or taking the shape, the support part 2 and the connecting sleeve 3 thereon are moved away from the side of the residual limb, thereby avoiding the support part 2 and the connecting sleeve 3 from interfering with the operation of the residual limb maker. Therefore, the practicality of the prosthetic receiving cavity trial-taking device is stronger.

[0055] It should be noted that the above-mentioned receiving cavity can be a plaster cavity, a temporary cavity or a formal cavity. Specifically, when taking the model, the above-mentioned prosthetic receiving cavity is a plaster cavity, and when trying on the prosthetic limb, the above-mentioned prosthetic receiving cavity is a temporary cavity or a formal cavity.

[0056] Optionally, the platform 1 includes a fixed platform 11 and a mounting ring 12, wherein:

[0057] The middle portion of the top surface of the fixed platform 11 is flat, forming the aforementioned standing position. That is, the fixed platform 11 is used for patients to stand. With the aid of the fixed platform 11, the entire device can be placed stably on the ground. The mounting ring 12 is rotatably mounted on the outer edge of the fixed platform 11, and the support portion 2 is mounted on the mounting ring 12. This allows the support portion 2 to be rotatably mounted on the platform 1, thereby achieving a movable connection between the support portion 2 and the platform 1. A brake portion 13 is installed between the mounting ring 12 and the fixed platform 11. This brake portion 13 is used to limit the rotation of the mounting ring 12 relative to the fixed platform 11. During use, if the support portion 2 needs to be rotated, the brake portion 13 is not engaged. Once the support portion 2 is rotated to the appropriate position, the brake portion 13 is engaged, thereby locking the support portion 2 in the appropriate position to the fixed platform 11. Of course, the support part 2 can also be rotatably mounted on the platform 1 in other forms, for example, an annular groove surrounding the standing position is opened on the top surface of the platform 1, and the bottom end of the support part 2 is inserted into the annular groove and can move in the annular groove.

[0058] Optionally, the mounting ring 12 includes a circle 121, an upper ring 122 and a lower ring 123, the fixed platform 11 is disc-shaped, the mounting ring 12 is annular, and a circle of convex wings 111 is provided on the circumferential side wall of the fixed platform 11, the convex wings 111 are located in the middle of the fixed platform 11, the upper ring 122 and the lower ring 123 are respectively bonded, clamped or bolted to the two ends of the circle 121 in the axial direction, and an interlayer adapted to the convex wings 111 is formed between the circle 121, the upper ring 122 and the lower ring 123, and the convex wings 111 are rotatably accommodated in the interlayer, so that the mounting ring 12 is rotatably mounted outside the fixed platform 11.

[0059] Of course, the circle 121 and the upper ring 122 can also be formed in one piece, and the lower ring 123 and the circle 121 can be connected together by bonding, bolting or clamping. The circle 121 and the lower ring 123 can also be formed in one piece, and the upper ring 122 and the circle 121 can be connected together by bonding, bolting or clamping.

[0060] The support portion 2 is mounted on the top surface of the upper ring 122 , and the brake portion 13 is mounted between the upper ring 122 and the fixing platform 11 .

[0061] Optionally, the brake portion 13 includes a rubber plate 131, a pressure block 132, and a first drive assembly. The upper ring 122 is provided with a through hole. A cover 14 covering the through hole is bolted to the top surface of the upper ring 122. The rubber plate 131 is hot-melt-connected to the through hole, thereby blocking the through hole. The pressure block 132 is overlapped on the rubber plate 131 and movably accommodated in the cover 14. The first drive assembly is installed in the cover 14 and connected to the pressure block 132. The first drive assembly is used to drive the pressure block 132 to move up and down in the cover 14. When braking, the first drive assembly drives the pressure block 132 to move downward so that the pressure block 132 presses the rubber plate 131 against the top surface of the convex wing 111, thereby utilizing the friction between the rubber plate 131 and the convex wing 111 to brake. When the brake is not applied, the first driving assembly drives the pressure block 132 to move upward so that the pressure block 132 releases the rubber plate 131, that is, the rubber plate 131 is not pressed tightly against the top surface of the convex wing 111. At this time, the friction between the rubber plate 131 and the top surface of the convex wing 111 is small or zero.

[0062] Specifically, the first drive assembly includes an electromagnet 133 and a spring 134. The pressure block 132 is an iron block mounted on the inner top wall of the housing 14. The spring 134 is supported between the top surface of the pressure block 132 and the inner top wall of the housing 14. During braking, the electromagnet 133 is de-energized, and the spring 134 forces the iron block downward, thereby pressing the rubber plate 131 against the top surface of the wing 111. The rubber plate 131 also functions to reduce vibration and noise.

[0063] When the brake is not in effect, the electromagnet 133 is energized to generate a magnetic force, thereby attracting the iron block to move upward, causing it to release the rubber plate 131. Of course, a power supply and a control module (such as a circuit board or chip) are also included. The electromagnet 133 and the power supply are both electrically connected to the control module. The control module is also electrically connected to a first switch, which is used to control the power supply between the electromagnet 133 and the power supply. Specifically, the first switch is mounted on the support portion 2 to facilitate medical personnel or prosthetists to control whether the brake portion 13 is in effect.

[0064] Optionally, the support portion 2 includes a mounting seat 21, an outer tube 22, an inner shaft 23 and a second drive assembly, wherein:

[0065] The mounting seat 21 is welded or hot-melted to the top surface of the upper ring 122, and the outer tube 22 is welded or hot-melted to the top of the mounting seat 21. The outer tube 22 is vertically arranged, and the inner shaft 23 is inserted into the outer tube 22 so as to move up and down. A mounting block 24 is provided at the top of the inner shaft 23, and the connecting sleeve 3 is connected to the mounting block 24. Specifically, the connecting sleeve 3 includes a ring body 31 for installing the prosthetic receiving cavity and a connecting shaft 32 fixed on the outer side wall of the ring body 31. The axial direction of the connecting shaft 32 is in the same direction as the radial direction of the ring body 31. The connecting shaft 32 is fixed to the mounting block 24 by insertion, clamping or bolting, thereby connecting the connecting sleeve 3 to the mounting block 24. It should be noted that the ring body 31 has been disclosed in the existing prosthetic molding workbench, so it will not be described in detail here.

[0066] A second drive assembly is mounted within the outer tube 22 and is connected to the inner shaft 23. The second drive assembly is used to drive the inner shaft 23, thereby raising and lowering the mounting block 24 and the connecting sleeve 3. This second drive assembly facilitates controlling the height of the connecting sleeve 3 relative to the standing position, making it easier to adjust the connecting sleeve 3 to the appropriate height during prosthetic socket fitting or prosthetic shaping.

[0067] Optionally, the second drive assembly is an electric telescopic rod 25 with an upwardly directed telescopic shaft. The electric telescopic rod 25 is mounted on the mounting base 21 and located within the outer tube 22. The bottom end of the inner shaft 23 is fixed, bolted, or pinned to the telescopic plug. Of course, the electric telescopic rod 25 is electrically connected to the control module. The control module is also electrically connected to a second switch, which is used to control the operating state of the electric telescopic rod 25. The second switch can be manipulated to control the extension and retraction of the electric telescopic rod 25, thereby controlling the lifting and lowering of the connecting sleeve 3. The first and second switches are both mounted on the mounting block 24, and both are wireless switches. Heat dissipation holes 221 for the electric telescopic rod 25 are provided on the wall of the outer tube 22, thereby facilitating heat dissipation of the electric telescopic rod 25 during operation.

[0068] Optionally, the outer diameter of the inner shaft 23 is smaller than the diameter of the top end of the outer tube 22. A sealing plate 26 is screwed or bolted to the top of the outer tube 22. The sealing plate 26 blocks the top end of the outer tube 22. A center hole adapted for the inner shaft 23 is provided in the center of the sealing plate 26. The inner shaft 23 slides up and down through the center hole. A guide assembly 4 is further provided between the mounting block 24 and the sealing plate 26. The guide assembly 4 is used to guide the raising and lowering of the mounting block 24. The sealing plate 26 can reduce the amount of dust that enters the outer tube 22, thereby protecting the electric telescopic rod 25. The guide assembly 4 can make the raising and lowering of the mounting block 24 more stable, thereby facilitating a more stable raising and lowering of the connecting sleeve 3.

[0069] Specifically, the guide assembly 4 includes a guide sleeve 41 and a guide rod 42 . The guide sleeve 41 is provided on the outer wall of the sealing plate 26 , and the guide rod 42 is provided on the outer wall of the mounting block 24 . The guide rod 42 is inserted into the guide sleeve 41 to slide up and down.

[0070] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
