Description

Technical Field

[0001] The present application relates to the technical field of prosthetics, and in particular, to a thigh prosthetic auxiliary profiling device. Background Art

[0002] A prosthetic limb is an artificial prosthesis specifically designed and fabricated by means and methods of engineering technology to make up for the amputated limb or the incompletely defective limb of a person, also known as a "prosthesis". Its main function is to replace part of the functions of the lost limb and enable the amputee to regain a certain degree of self-care and working ability.

[0003] The receiving socket in a prosthetic limb is the most important component. It directly contacts the residual limb, supports the body's gravity, controls the movement of the prosthetic limb, and the comfort of wearing the prosthetic limb entirely depends on whether the receiving socket is appropriate. Therefore, profiling is required before installing the prosthetic limb.

[0004] Currently, when performing the female profiling work of the receiving socket, it needs to be completed manually by experienced staff. The hands of the staff remain in a constant position for a long time to apply a fixed external force to make the plaster bandage fit tightly with the affected limb. However, the manual profiling process is not only inefficient but also has a large working intensity. Once the hands of the staff loosen, it will cause changes in the size of the receiving socket. For this reason, a thigh prosthetic auxiliary profiling device is proposed. Utility Model Content

[0005] In order to prevent the hands of the staff from loosening during the profiling process and reduce the working intensity, the present application provides a thigh prosthetic auxiliary profiling device.

[0006] A thigh prosthetic auxiliary profiling device provided by the present application adopts the following technical solution: A thigh prosthetic auxiliary profiling device includes a receiving socket profiling splint. Two first perforated fixing seats are fixedly installed on the outer surface of the receiving socket profiling splint through two groups of bolts. Each first perforated fixing seat is rotatably connected to two perforated rack connecting belts through two first connecting shafts. Two second perforated fixing seats are fixedly installed on the outer surface of the receiving socket profiling splint through two groups of bolts. The inner wall of each second perforated fixing seat is rotatably connected to a perforated clamping plate through a second connecting shaft. A return spring is sleeved on the outer surface of each second connecting shaft. The right ends of the two perforated rack connecting belts respectively penetrate through the two second perforated fixing seats and extend to the right side of the second perforated fixing seats. Two guiding cylinders are fixedly connected to the front surface of the receiving socket profiling splint. Two guiding insertion strips are fixedly connected to the front surface of the receiving socket profiling splint. The left ends of the two guiding insertion strips respectively extend into the interiors of the two guiding cylinders.

[0007] Optionally, a tooth groove adapted to the perforated rack connecting belt is formed on the back surface of the perforated clamping plate, and the tooth groove is meshed with the perforated rack connecting belt.

[0008] Optionally, a pressing plate is provided in front of each perforated rack connecting belt, and the right side surfaces of the two pressing plates are respectively fixedly connected to the left side surfaces of the two perforated clamping plates.

[0009] Optionally, a limiting groove is provided on the inner wall of each second perforated fixing seat, and two stoppers are fixedly connected to the inner wall of each second perforated fixing seat.

[0010] Optionally, spring positioning grooves are provided on the inner bottom wall and the inner top wall of the second perforated fixing seat, and the mutually remote ends of the two return springs respectively extend into the two spring positioning grooves.

[0011] Optionally, the two ends of the two groups of return springs are respectively in contact with the back surfaces of the two perforated clamping plates and the inner wall of the second perforated fixing seat.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. By providing an acceptance cavity profiling splint, the present utility model can wrap the thigh part to be profiled, and by using the cooperation of the perforated rack connecting belt and the second perforated fixing seat, the two ends of the acceptance cavity profiling splint can be made to approach each other, so that the acceptance cavity profiling splint can tighten the profiling part.

Detailed implementation manners

[0023] The following further describes the present application in detail with reference to the attached Figure 1 —7.

[0024] The embodiment of the present application discloses a thigh prosthesis auxiliary profiling device, including a receiving cavity profiling splint 1. Two first perforated fixing seats 2 are fixedly installed on the outer surface of the receiving cavity profiling splint 1 through two groups of bolts. Two threaded mounting holes are provided on the inner wall of the first perforated fixing seat 2, and the threaded mounting holes can facilitate the disassembly and installation of the first perforated fixing seat 2. Each first perforated fixing seat 2 is respectively rotatably connected to two perforated rack connecting belts 4 through two first connecting shafts 3. Two second perforated fixing seats 5 are fixedly installed on the outer surface of the receiving cavity profiling splint 1 through two groups of bolts.

[0025] Two threaded mounting holes are provided inside the second perforated fixing seat 5, and the second perforated fixing seat 5 can be installed through the threaded mounting holes, so as to facilitate the disassembly and installation of the second perforated fixing seat 5. A perforated clamping plate 8 is rotatably connected to the inner wall of each second perforated fixing seat 5 through a second connecting shaft 6. The second connecting shaft 6 enables the perforated clamping plate 8 to rotate, so that the perforated clamping plate 8 can control the perforated rack connecting belt 4 by using the elastic force of the return spring 7. A tooth groove 81 adapted to the perforated rack connecting belt 4 is provided on the back surface of the perforated clamping plate 8.

[0026] The tooth groove 81 meshes with the perforated rack connecting belt 4. By providing the tooth groove 81, it can cooperate with the teeth of the perforated rack connecting belt 4 to position the perforated rack connecting belt 4, enabling the perforated rack connecting belt 4 to tighten the receiving cavity profiling splint 1, so that the receiving cavity profiling splint 1 can stably apply an external force to the profiling position, and can prevent the perforated rack connecting belt 4 from resetting, avoiding loosening of the receiving cavity profiling splint 1 and causing inaccurate dimensions. A return spring 7 is sleeved on the outer surface of each second connecting shaft 6.

[0027] Both ends of the two return springs 7 are respectively in contact with the back surface of the two perforated clamping plates 8 and the inner wall of the second perforated fixed seat 5, ensuring that during the use of the return spring 7, the elastic force can be applied to the perforated clamping plate 8. The right ends of the two perforated rack connecting belts 4 respectively penetrate through the two second perforated fixed seats 5 and extend to the right side of the second perforated fixed seat 5. Two guide cylinders 9 are fixedly connected to the front surface of the receiving cavity profiling splint 1, and two guide inserts 10 are fixedly connected to the front surface of the receiving cavity profiling splint 1. The left ends of the two guide inserts 10 respectively extend into the two guide cylinders 9. Through the cooperation of the guide cylinder 9 and the guide insert 10, the two ends of the receiving cavity profiling splint 1 can be limited, preventing misalignment during profiling.

[0028] In this embodiment, a pressing plate 82 is provided in front of each perforated rack connecting belt 4. The right side surfaces of the two pressing plates 82 are respectively fixedly connected to the left side surfaces of the two perforated clamping plates 8. By providing the pressing plate 82, it is convenient to control the rotation of the perforated clamping plate 8 with the second connecting shaft 6 as the center, so that the perforated clamping plate 8 can drive one end of the tooth groove 81 to rotate, separating the tooth groove 81 from the teeth of the perforated rack connecting belt 4, thereby facilitating the removal of the perforated rack connecting belt 4 from the second perforated fixed seat 5.

[0029] Please refer to Figure 3 and Figure 4 , a limiting groove 52 is provided in the inner wall of each second perforated fixed seat 5, and two stoppers 51 are fixedly connected to the inner wall of each second perforated fixed seat 5. By providing the limiting groove 52, after the perforated rack connecting belt 4 is inserted into the second perforated fixed seat 5, it can guide the perforated rack connecting belt 4 to prevent the perforated rack connecting belt 4 from moving out of the second perforated fixed seat 5 and causing loosening of the perforated rack connecting belt 4.

[0030] In order to increase the stability of the return spring 7, spring positioning grooves 53 are provided on the inner bottom wall and the inner top wall of the second perforated fixed seat 5. The mutually remote ends of the two return springs 7 respectively extend into the two spring positioning grooves 53. The spring positioning grooves 53 can be used to receive one end of the return spring 7, so that the return spring 7 remains stable during operation.

[0031] The implementation principle of an auxiliary shaping device for a thigh prosthesis in an embodiment of the present application is as follows: During use, the staff first covers the thigh part of the affected limb with a plaster bandage, then spreads the socket shaping splint 1 outside the shaping area, and then wraps the socket shaping splint 1 around the shaping area. Insert the guiding insert 10 into the guiding cylinder 9 to limit the socket shaping splint 1. Insert one end of the perforated rack connecting belt 4 close to the second perforated fixing seat 5 into the second perforated fixing seat 5. Subsequently, pull the perforated rack connecting belt 4 to make the perforated rack connecting belt 4 push the two ends of the socket shaping splint 1 closer to each other, so that the socket shaping splint 1 can apply an external force to the shaping area to prevent loosening of the shaping area. And after the shaping is completed, by pushing the pressing plate 82 to make the pressing plate 82 approach the socket shaping splint 1, the tooth grooves 81 of the perforated card plate 8 are separated from the perforated rack connecting belt 4, thereby releasing the restriction on the socket shaping splint 1, so that the staff can disassemble the socket shaping splint 1 after the shaping is completed.

[0032] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
