Description

Technical Field

[0001] The utility model relates to the technical field related to thigh prosthesis installation, in particular to a thigh prosthesis installation and fixing structure. Background Art

[0002] A prosthesis is an artificial prosthesis specially designed, manufactured and assembled using engineering technology to compensate for the limbs of amputees or incomplete limb defects. It is also called an "artificial limb". Its main function is to replace some of the functions of the lost limbs and enable amputees to restore a certain degree of self-care and work ability. It is applicable to amputees due to diseases, traffic accidents, industrial accidents, sports injuries, etc. The prostheses currently on the market are generally customized according to the patient's body shape when they are manufactured. After customization, when the patient wears it, he generally needs to accurately install the foot at the top of the prosthesis in the front position, and then fix the position through the suction air plug. However, since the prosthesis is highly consistent with the patient's residual limb, when the patient completes the installation of the prosthesis and needs to move its position, the entire prosthesis can only be disassembled again to move the position. In addition, multiple disassembly and installation will cause secondary damage to the patient's wound. Utility Model Content

[0003] The purpose of the utility model is to provide a thigh prosthesis installation and fixing structure to solve the problem raised by the above-mentioned background technology that the prosthesis installation and fixing structure currently on the market, when the patient installs and wears it, because the prosthesis and the patient's residual limb are highly matched, when the patient completes the installation of the prosthesis and needs to move its position, the entire prosthesis can only be disassembled again before the position movement work can be carried out, and multiple disassembly and installation will cause secondary damage to the patient's wound surface.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thigh prosthesis installation and fixing structure, including a fastening cover, the interface of which is arranged in a "U"-shaped structure;

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 , the utility model provides a technical solution: a thigh prosthesis installation and fixing structure, including a fastening cover 1, whose interface is arranged in a "U"-shaped structure;

[0028] The supporting mechanism 3 is a main body of the thigh prosthesis, used to support the patient's legs;

[0029] Also includes:

[0030] The mounting mechanism 2 is arranged inside the supporting mechanism 3, and the mounting mechanism 2 and the supporting mechanism 3 are slide-limited by the sliding mechanism 5 and the sliding groove mechanism 4;

[0031] The present application provides a prosthesis installation and fixing mechanism that drives a sliding mechanism 5 and a slide groove mechanism 4. Specifically, when using it, first, the patient only needs to engage the residual limb of the leg into the inside of the installation mechanism 2, and then the entire support mechanism 3 can be controlled to slide outside the installation mechanism 2, so that the sliding mechanism 5 can slide and rise inside the slide groove mechanism 4. When it reaches the top position, at this time, it is only necessary to tighten the cover 1 so that it is engaged and installed with the top of the support mechanism 3, thereby achieving the effect of installation and tightening. Finally, the prosthesis can be used.

[0032] Further, according to Figure 2-5 As shown, fixing pins 11 are distributed at equal angles on the bottom of the fastening cover 1 , and the fastening cover 1 is engaged with the outside of the supporting mechanism 3 .

[0033] A slide groove mechanism 4 is arranged outside the mounting mechanism 2 , and the mounting mechanism 2 can rotate inside the supporting mechanism 3 .

[0034] The chute mechanism 4 comprises:

[0035] The circular groove 44 is arranged in a circular shape at the middle position of the outside of the mounting mechanism 2, and vertical grooves 42 are distributed at equal angles above the circular groove 44. An arc groove 41 is also arranged at the top of the vertical groove 42. The arc groove 41, the vertical groove 42 and the circular groove 44 penetrate each other.

[0036] A through hole 43 is further provided between the top of the arc groove 41 and the top of the mounting mechanism 2 , and the through holes 43 are also distributed at equal angles inside the mounting mechanism 2 , and the number and position of the through holes 43 are the same as the position and number of the vertical grooves 42 .

[0037] The sliding mechanism 5 comprises:

[0038] The sliding block 51 is arranged at the top inner side of the support mechanism 3, and the sliding blocks 51 are distributed at equal angles on the inner wall of the support mechanism 3, and the number and angle of the sliding blocks 51 are consistent with the position and number of the vertical slots 42;

[0039] The vertical groove 42 is engaged with the sliding block 51 , and a mounting hole 52 is embedded in the middle of the sliding block 51 .

[0040] The sliding block 51 can also be engaged with the arc-shaped groove 41, and when the sliding block 51 is engaged in the arc-shaped groove 41, the position of the mounting hole 52 inside the sliding block 51 corresponds to the position of the through hole 43;

[0041] The mounting hole 52 and the through hole 43 have the same size, and are respectively engaged with the fixing pin 11;

[0042] Specifically, when controlling the support mechanism 3 to change its angle, at this time, the staff only needs to rotate the entire support mechanism 3 so that the support mechanism 3 drives the sliding block 51 inside it to rotate. When it rotates to the bottom of the vertical groove 42, at this time, the entire support mechanism 3 is controlled to move upward, so that it drives the sliding block 51 to slide inside the vertical groove 42. When the sliding block 51 slides to the topmost position, at this time, it is only necessary to control the entire support mechanism 3 to rotate again, so that the entire sliding block 51 rotates to the top position of the arc groove 41. At this time, the top of the support mechanism 3 and the top of the mounting mechanism 2 are in the same horizontal plane. Therefore, the fastening cover 1 is taken, so that it drives the fixing pin 11 downward to engage with the through hole 43 and then the mounting hole 52, so that the "U"-shaped structure at its top engages with the outside of the support mechanism 3, thereby completing the position fixing work of the support mechanism 3. Finally, the entire thigh prosthesis body can be used. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
