An elastic intramedullary fixation device includes a serpentine frame and a shell, the inner surface of the shell is rotatably connected with a locking rod, one end of the locking rod is inserted with a key rod, one end of the shell is inserted with a clamping rod, the outer surfaces of the clamping rod and the key rod are sleeved with a connecting sleeve, the outer surfaces of the clamping rod and the key rod are provided with a connecting component, and the surfaces of the clamping rod and the shell are provided with a self-locking component. By configuring a connecting component and a self-locking component, the connecting component not only allows for the adjustment of the positional relationship between the key rod and the clamping rod, but also enables engagement with the locking component, thereby enhancing the stability of the connection between the clamping plate and the shell.

A proximal-femur intraosseous release device includes a release mechanism. A primary fixing mechanism is provided at one end of the release mechanism, the primary fixing mechanism includes a first shell, and a second shell, a first triangular block and a second triangular block are arranged inside the first shell; the second shell is screwed to the first shell through threads, a bottom of the second shell is rotatably connected with the first triangular block, the first triangular block is slidably connected with the first shell, a bottom surface of the first triangular block is an inclined surface, the second triangular block is located at a bottom of the first triangular block, a top surface of the second triangular block is an inclined surface, and a through hole matched with the second triangular block is formed in the first shell.

Proximal-femur intraosseous release device

A method of providing memory accesses for a multi-core processor includes reserving a group of pins of a multi-core processor to transmit either data or address information in communication with one or more memory chips, receiving memory access requests from the plurality of processor cores, determining granularity of the memory access requests by a memory controller, and dynamically adjusting the number of pins in the group of pins to be used to transmit address information based with the granularity of the memory access requests.
