A polyaxial screw system and method are provided. The system comprises a receiver having a pivot area defined by a pivot joint or a material between a pair of receiver walls or members that permit the receiver walls or members to move or pivot relative to each other so that a dimension of a socket area can be changed. The socket area is defined by socket walls that when at least one of the receiver members pivots relative to another receiver member or wall, a distance between the socket walls gets smaller so that the socket walls can engage and lock against a head of a polyaxial screw.

The present disclosure is directed towards a socket and suspension system that offers the user increased ease of donning the prosthesis, volume adjustability, and improved circulation. The prosthetic includes a socket and liner. The socket and liner can be custom made for the amputee or prefabricated. The liner acts as an interface between the custom socket and the amputee's residual limb. Moving fluid in or out of the area between the liner and the socket causes the liner to push away from the socket wall or pull into the socket wall thereby changing the volume inside the socket. Moving the liner closer to the socket wall enlarges the volume inside the socket making it easier for the patient to put on the prosthetic. The socket and suspension system can include a pump which can manually or automatically adjust the volume inside the socket and suspension of the prosthesis.

The invention relates to a preparation method and an application of a bioactive factor loaded temperature-sensitive composite gel carrier. The method comprises the following steps: 1. preparing a sodium alginate hydrosol; 2. preparing a sodium alginate-chitosan hydrosol through the hydrosol prepared by the step 1; 3. preparing a sodium glycerophosphate solution, adding the sodium alginate-chitosan hydrosol under a stirring condition to obtain a uniform sol; 4. adding adiponectin to the uniform sol prepared by the step 3, adding Ca<2+> and uniformly stirring; and 5. adding calcined bone powder to the sol prepared by the step 4 and uniformly mixing to obtain the bioactive factor loaded temperature-sensitive composite gel carrier. The preparation method, for shortcomings of the prior art of repairing missing and defects of an extraction socket wall, can greatly improve bioactivity, biocompatibility, mechanical tolerance and a slow release performance of a normal gel carrier, thus providing a novel repairing material for treatment of repairing missing and defects of the extraction socket wall.

A fitting including an electrode assembly mounted and sealed therein. The fitting configured to be positioned within an aperture in a wall of a socket of a prosthetic apparatus.

A prosthetic hard socket has a modified curvature and / or shape, which eliminates or de-emphasizes the patellar bar to eliminate or reduce pressure on the wearer's patellar tendon, and, instead, enhances support of the anterior tibial condyle and / or tibial tubercle. Thus, the preferred socket is designed with the patellar tendon preferably not being weight-bearing. The preferred curvature and / or shape comprises a lowered socket edge and / or a gap in the socket wall in the region of the patellar tendon, so that the hard structure of the socket does not directly support or press upon the patellar tendon. The invented socket may include inwardly-protruding regions on each side of the lowered edge / gap, for helping to “capture” or otherwise press on a portion of the tibia for improved rotational control. This combination of shapes and curvatures provides for improved rotational control, comfort, and range of motion including even full extension or hyperextension. A flexible and / or cushioning member may be placed in the gap / trough (that is caused by the lowered edge or removed wall portion), for example, a fabric, leather, rubber, or other member may be attached to the socket to across a V-shaped trough of the lowered edge of the hard socket.

An optical connector comprises four main components, namely a clamp; a housing into which the clamp slides; two optical elements, a transmitter and a receiver; and an EMI metal shield surrounding the elements. The clamp has two parallel through holes for receiving fibre terminations, each through-hole having a generally conical mouth for convenient guidance of a fibre termination. Inside of the through-holes there are side resilient clamp members, and there is a single central clamp member. The clamp is of moulded plastics construction, and the clamp members are resilient in the lateral plane. The central clamp member on the other hand has little flexibility and remains essentially static throughout the clamping operation. Each resilient clamping member has a tooth at its end for snap-fitting engagement with the housing at open and closed positions. Fibre terminations are inserted through the clamp mouths and the through-holes and into the sockets of the housing. The clamp is then simply pushed inwardly so that teeth in the socket walls bite into the fibre claddings.
