Description

Positioning guide device for acromioclavicular joint dislocation implantation operation Technical Field The utility model belongs to the field of orthopedic surgical instruments, and particularly relates to a positioning guide for acromioclavicular joint dislocation implantation surgery. Background When performing an operation for dislocation of acromioclavicular joint, it is necessary to cut open a passage to leak out bone, connect the bone at the dislocation of joint (hereinafter referred to as "upper bone") with the bone at the lower part (hereinafter referred to as "lower bone") by means of a tab steel plate, drill a passage in both bones during the operation, then implant a steel plate, and penetrate the tab into the passage to connect both ends of the steel plate. When drilling, need hold the below skeleton through the locating terminal of location navigation device, guide the drill bit through the navigation section of thick bamboo and bore, at the in-process of drill bit down turning, go up the skeleton because one end has dislocation, can appear rocking when contacting the drill bit, perhaps skid, consequently need fix, as the patent application of application number 202211647807.5 discloses a acromioclavicular joint dislocation operation device, it fixes this skeleton through U type spare, but this U type spare is bulky to can not warp, need great wound when getting into the patient body. Disclosure of utility model The utility model aims to solve the problems and provide a positioning guide for acromioclavicular joint dislocation implantation operation. The utility model realizes the above purpose through the following technical scheme: The utility model provides a acromioclavicular joint dislocation implants location director of operation, includes connecting portion, locates the location portion and the drill bit guiding tube at connecting portion both ends, the surface that the drill bit guiding tube is close to the bottom is provided with screw-thread fit's rotating sleeve, the outside of rotating sleeve is provided with the fixed axle with rotating sleeve axial parallel, is provided with the arc cover on the fixed axle rotation, the non-articulated end of arc cover is provided with the clamping part, arc cover and fixed axle complex position is provided with the spacing arch that is used for restricting arc cover rotation stroke. As a further optimization scheme of the utility model, the surface of the positioning part far away from the connecting part is provided with a positioning groove, a through hole is formed in the positioning groove, the drill bit guide cylinder points to the positioning groove, the purpose of positioning is achieved by buckling the positioning groove on the lower skeleton, and the through hole is used for passing a drill bit. As a further optimization scheme of the utility model, the end part of the connecting part, which is close to the drill guide cylinder, is detachably provided with the damping sliding sleeve, the damping sliding sleeve is sleeved outside the drill guide cylinder, and the connecting part is detachably connected with the drill guide cylinder, so that the drill guide cylinder is convenient to operate, the clamping part can form a clamping effect on an upper bone through deformation, and the damping sliding sleeve is fixed with the connecting part after clamping.
