支撐骨骼強度裝置的撐開器模組

A spreader module for supporting bone strength device comprises a spreader module, which comprises an outer sleeve, a main body and a grip. The interior of the outer sleeve is axially penetrated with a through hole having its inner periphery at one end configured with a joining hole, in which the joining hole and a joining portion of an implant are fitted together. The main body is in a hollow shape and limits a packing block to only axially move on the main body. The periphery of the grip is provided with a second external thread having one end pivoted with a rotating member and another end disposed with a twisting portion. By continuously applying a torque onto the grip, the outer sleeve may compress the implant and force the expansion portion of the implant to be compressed and deformed through the twisting torque of the thread, thereby forming an expandable implant in a multi-level arc shape and capable of adjusting for different expansion ranges.
