TECHNICAL FIELD
[0001] The utility model relates to artificial limb technical field, concretely is a prosthesis buffer structure. BACKGROUND
[0002] Prosthesis, also known as "artificial limb", is a prosthetic limb used to compensate for the function of the missing limb, such as upper limb prosthesis and lower limb prosthesis, which is made of aluminum plate, wood, leather, plastic and other materials, and its joints use metal parts. The mainstream of the current prosthesis industry is titanium alloy and carbon fiber material. Artificial limb refers to artificial limbs used to replace the dysfunction (temporary or permanent) of limbs or to conceal limb disabilities. The biggest difference between artificial limbs and artificial bodies (such as artificial breasts, artificial noses, and wigs) is that artificial limbs are more functional and refer to upper and lower limbs. Among them, artificial legs are also included.
[0003] The artificial leg structure currently used in the market is simple and has single function, does not have the functions of bacteriostasis and ventilation, and is easy to cause bacteria breeding and moisture overheating in the contact part between the user and the artificial leg, which is not conducive to the use of the user. Therefore, an antibacterial artificial limb socket is proposed.

The prior art has an outer cylinder and an inner cylinder. The inner cylinder includes a main body attached to the inner wall of the outer cylinder. A plurality of cylindrical cavities are provided in the main body. When the device is worn, the main body can be compressed to form a buffer under the action of the cylindrical cavities, increasing the comfort when worn. At the same time, through the setting of the through hole communicating with the cylindrical cavity, ventilation is carried out through the channel formed by the through hole and the cylindrical cavity to prevent bacteria breeding and achieve the purpose of antibiosis. Although the prior art can solve the problems of moisture overheating and bacteria breeding by the above-mentioned way, the prior art needs to install the arc-shaped clamping plate on the outer cylinder main body during use. When installing the arc-shaped clamping plate, the knob is rotated to drive the tightening rotary wheel to rotate, and the tightening rotary wheel makes the tightening rope wind around the surface of the tightening rotary wheel to tighten the tightening rope, so as to fix the device and the limb through the arc-shaped clamping plate. The structure adopted by the prior art is complex, and the installation process of the arc-shaped clamping plate is complex. Therefore, in order to solve the problems of complex structure and complicated installation process of the arc-shaped clamping plate in the prior art, the present case is proposed to solve the problems.

[0025] Please refer to Figures 1 to 3The utility model provides technical scheme: a prosthesis buffer structure, including inner tube 3 and outer tube, inner tube 3 adopts latex material to be made. The outer tube is formed by support cylinder 2, arc clamping plate 4, and support cylinder 2 is detachably connected with arc clamping plate 4. The cross section of arc clamping plate 4 is semicircular arc shape. The lower end of outer tube is fixedly connected with connecting piece 1.
[0026] Wherein, inner tube 3 is the cushion layer, avoids human body limbs and outer tube direct contact, and inner tube 3 is used to improve the comfort of human body limbs. Support cylinder 2 and arc clamping plate 4 jointly constitute the outer tube. Arc clamping plate 4 is detachably connected with support cylinder 2, to facilitate the human body limbs to be placed in the outer tube.
[0027] The both sides wall of arc clamping plate 4 is fixedly connected with the insert strip 9, and the insert strip 9 on the both sides wall of arc clamping plate 4 is parallel, and the both sides wall of support cylinder 2 is provided with the slot 11, and the card block 8 is longitudinally slidably arranged on the support cylinder 2 and located in the slot 11.
[0028] Wherein, arc clamping plate 4 is inserted with the slot 11 of support cylinder 2 through insert strip 9, and card block 8 is used for limiting and clamping insert strip 9 in slot 11, so that insert strip 9 cannot move, and then the fixation of arc clamping plate 4 is realized, that is, arc clamping plate 4 is installed on support cylinder 2.
[0029] The connecting column 6 is slidably connected with the lower end of the connecting column 6 and the one end of the card block 8. The lower end of the connecting column 6 is fixedly connected with the spring 5, and the lower end of the spring 5 is fixedly connected with the support cylinder 2. The upper end of the connecting column 6 is fixedly connected with the pull block 7.
[0030] Wherein, connecting column 6 is used to drive card block 8 to longitudinally slide in slot 11, and when connecting column 6 drives card block 8 to slide up, card block 8 cancels the limiting and clamping of insert strip 9. When connecting column 6 drives card block 8 to slide down, card block 8 limits and clamps insert strip 9.
[0031] Specifically, a plurality of longitudinal air ducts are formed in the wall of the inner tube 3, and a plurality of ventilation holes are formed in the inner wall of the inner tube 3, and each air duct and each ventilation hole are communicated.
[0032] Wherein, longitudinal air duct and ventilation hole are used for ventilation, to avoid the human body limbs in the inner tube 3 appear humid and hot, breed bacteria. Since the inner tube 3 adopts latex, has certain flexibility, avoids the jam of longitudinal air duct and ventilation hole due to too much flexibility, in the specific implementation, the rubber tube with certain hardness relative to latex can be arranged in the longitudinal air duct and ventilation hole, to guarantee the ventilation effect.

[0035] In use, when the device is worn, the limb is wrapped by the inner cylinder 3, and the inner cylinder 3 is flexible and compressible as a whole under the action of the cavity to form a buffer, thereby increasing the comfort when worn. The longitudinal air duct and the ventilation hole form a ventilation pipeline, which is convenient for ventilation and prevents bacteria from breeding. The insertion strip 9 on the surface of the arc-shaped clamping plate 4 corresponds to the insertion slot 11 on the supporting cylinder 2, the arc-shaped clamping plate 4 drives the insertion strip 9 to move, when one side of the insertion strip 9 contacts one side of the clamping block 8, the clamping block 8 is driven to move upward due to the action of the inclined surface, and the connecting column 6 and the pull block 7 are driven to move upward, the arc-shaped clamping plate 4 is continuously moved, and when the insertion strip 9 moves to a certain distance, the clamping block 8 is clamped into the clamping groove 10 on the insertion strip 9 due to the reset action of the gravity and the spring 5, so as to realize the cooperation and installation of the arc-shaped clamping plate 4 and the supporting cylinder 2.
[0036] When the limb needs to be taken out, the pull block 7 is only pulled upward, the connecting column 6 and the clamping block 8 are driven to move upward, the clamping block 8 is separated from the clamping groove 10 on the insertion strip 9, and at this time the supporting cylinder 2 and the arc-shaped clamping plate 4 are fixed, and the arc-shaped clamping plate 4 is removed to complete the disassembly.
[0037] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
