Description
Technical Field
The utility model relates to an artificial limb shell, which belongs to the technical field of artificial limbs.
Background
Artificial limbs are artificial prostheses, also called "artificial limbs", which are specially designed and assembled to compensate for amputees or incomplete limb defects. The artificial limb mainly has the function of replacing partial lost limb to enable an amputee to recover certain self-care and working capacity, and is suitable for amputees caused by diseases, traffic accidents, industrial accidents, sports injuries and the like. Usually, the substitute limb for which the prosthesis is designed has a stronger functionality, and in order to compensate for the appearance defect, usually the user installs a shell on the outer side of the prosthesis, which is shaped like a real limb part, so that the prosthesis is more like a real limb after being worn, and on the other hand, the prosthesis can be protected. In a conventional prosthesis shell, for example, a prosthesis shell disclosed in chinese patent document CN209075047U, a locking assembly is integrally fixed to a main shell, and the prosthesis shell can be fixed to a prosthesis by the locking assembly. Firstly, the existing artificial limb shell is inconvenient to mount and dismount, and the locking assembly needs to be locked or unlocked each time; secondly, the artificial limb shell and the locking component are designed into an integral structure, so that the cost of the artificial limb shell is higher; and thirdly, the locking component is fixedly arranged on the shell, so that the production and the processing are inconvenient, and the fixed part is often easy to damage, so that the locking component falls off.
SUMMERY OF THE UTILITY MODEL

In order to achieve the above object, the present invention provides a prosthetic shell, which comprises a shell and a locking assembly detachably disposed on the shell; the shell is cylindrical and is provided with a slot extending along the length direction of the shell, and the slot can be opened so as to enable the locking component to enter the interior of the shell; the locking assembly at least comprises an elastic body, and the inner side wall of the shell can press the elastic body.
The locking assemblies are two groups and are used for being assembled on the inner side of the shell at intervals.
The elastic body is annular and is provided with an opening part.
The locking assembly further comprises a fastener positioned on the inner side of the elastic body, the fastener is used for being fixedly installed on a prosthesis, and the fastener and the elastic body are arranged in a separable mode.
And a clamping groove for accommodating the fastener is arranged on the inner side wall of the elastic body.
The fastener includes can be mutually the amalgamation and pass through the fixed at least two fasteners mutually of bolt.
The slotted part is provided with a buckle.
The elastomer is a rubber body, an emulsion body or a silica gel body.
The shell is made of resin or metal.
The artificial limb shell is an upper artificial limb shell or a lower artificial limb shell.
Adopt above-mentioned technical scheme, the utility model discloses an artificial limb shell, casing and the separable setting of locking Assembly are fixed in on the artificial limb through the locking Assembly centre gripping, install locking Assembly in the casing again, compress tightly the elastomer through shells inner wall, are convenient for to the change and the installation of casing, and the elastomer can play the cushioning effect simultaneously, improves the protection to the disabled.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the artificial limb shell of the present invention comprises a shell 1 and a locking assembly detachably disposed with the shell 1; the shell 1 is of a cylindrical type for covering the prosthesis on the inside thereof, and the locking assembly is used for clamping on the prosthesis. A slot 11 extending along the length of the housing 1 is provided in the housing 1, and the slot 11 can be opened to allow the locking assembly to enter the housing 1. The shell 1 is made of resin or metal and has certain elastic deformation capacity, so that the shell 1 can be pulled open towards two sides along the position of the slot 11, the gap of the slot 11 is enlarged, and the locking assembly and the artificial limb can be plugged into the slot. The locking assembly at least comprises an elastic body, and after the slot 11 is closed, the inner side wall of the shell 1 can press the elastic body, so that the locking assembly is pressed and fixed. The slot 11 is provided with a buckle 12 and a buckle groove 120, the slot can be locked by the buckle 12, so that the slot can not be separated at will, and the locking component is prevented from moving inside the shell 1.
In this embodiment, taking the outer shell of the lower limb prosthesis as an example, the locking assemblies are two groups, including an upper elastic body 21 positioned at the upper part and a lower elastic body 22 and a fastener 23 positioned at the lower part, and are used for fixing the upper part and the lower part of the prosthesis at intervals. A clamping groove 221 for accommodating the fastening piece 23 is arranged on the inner side wall of the lower elastic body 22, the fastening piece 23 is detachably mounted in the clamping groove 221, and is clamped through the clamping groove 221, so that the artificial limb, the lower elastic body 22 of the fastening piece 23 and the shell 1 are integrally fixed. As shown in fig. 3 and 4, the fastening member 23 includes two semicircular ring- shaped fasteners 231, 232 capable of being engaged with each other and fixed by bolts, fastened to the stem of the prosthesis by the two fasteners 231, 232, and then installed into the lower elastic body 22 inside the shell 1. When the shell of the artificial limb needs to be replaced, the buckles 12 at the positions of the grooves 11 of the shell 1 are separated, then the grooves 11 are opened for a certain distance, so that the upper elastic body 21 and the lower elastic body 22 lose the extrusion of the inner side wall of the shell 1, and the artificial limb and the fasteners 23 can be easily taken out of the shell 1.
The upper elastic body 21 and the lower elastic body 22 are ring-shaped and provided with opening portions 210, 220, respectively, the opening portions 210, 220 being located at positions opposite to the slots 11 when mounted to the inside of the housing 1. The elastomer can be a rubber body, an emulsion body or a silica gel body, and can be other materials capable of realizing similar functions.
In the present embodiment, the prosthesis shell is only described as an example of a lower limb prosthesis shell, and in other embodiments, the prosthesis shell may be an upper limb prosthesis shell.
By adopting the technical scheme, the artificial limb shell of the utility model wraps the artificial limb body by using the single shell body 1, when in assembly, the fastening piece 23 is firstly connected with the artificial limb through the bolt, and then the shell body 1 is inserted into the artificial limb through the elastic body for connection; the shell 1 can adopt an individualized skin design, and different shells 1 can be conveniently used by multiple occasions and groups; the fastener 23 is designed to be convenient for matching with various artificial limb models, and is convenient and firm to install. The elastomer can provide a buffer effect when meeting a strong external force condition, and the protection to the disabled is also improved while the elastomer is firmly installed. The design reduces the use cost as much as possible under the premise of meeting the function, improves the cost performance of the product and enables more disabled persons to get up and get down.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
