Description

Artificial shoulder joint prosthesis assembly Technical Field The utility model relates to the technical field of surgical instruments, in particular to an artificial shoulder joint prosthesis component. Background Artificial shoulder arthroplasty is a procedure for treating severe disease or injury to the shoulder by removing part or all of the damaged shoulder and replacing the artificial shoulder components, thereby restoring the function of the shoulder and reducing pain. When replacing the artificial parts, the installation of the parts on the scapula side is difficult, the existing design is to use screw fixation, usually 1 central screw with 6.5mm diameter is matched with 2 to 4 peripheral screws with 4.5mm diameter, for example, publication number CN107184293a discloses a reverse artificial shoulder joint prosthesis, which adopts a glenoid plate with a plurality of screws on one side for inserting into the scapula. This type of fixation is very difficult for a physician to screw in a thin scapula if the screw is not threaded in the same direction or if the screw is too long, it may even injure the suprascapular nerve that crawls around the scapula. Thus, there is a need for further improvements in the fixation of the glenoid relative to the scapula for an artificial shoulder joint prosthesis assembly. Disclosure of utility model The utility model aims to provide an artificial shoulder joint prosthesis component which aims to solve the technical problem of the structure of a superior shoulder spittoon. The artificial shoulder joint prosthesis assembly of the present utility model is realized as follows: A prosthetic shoulder joint assembly comprising: A glenoid bulb and a glenoid backboard connected with the glenoid bulb by a locking screw, wherein The glenoid backplate is adapted to be secured to the scapula by at least two wires; The shoulder spittoon backboard is provided with at least two threading holes which are suitable for one-to-one connection with two wire belts; The wire strap comprises a connecting strap connected with the glenoid backboard, an annular coil connected with one side end of the connecting strap, which is positioned on the glenoid backboard and faces away from the glenoid bulb, and a strap loop titanium plate connected with one end of the annular coil, which is far away from the connecting strap. In an alternative embodiment of the utility model, the glenoid backplate adopts a circular shaped structure, and The circle center of the glenoid backboard is provided with a nail hole which is matched with the locking screw. In an alternative embodiment of the utility model, four threading holes are uniformly formed on the glenoid backboard around the circumferential side of the nail hole. In an alternative embodiment of the utility model, each of the threading holes comprises two through holes extending through the glenoid backboard in the axial direction and a barrier located between the two through holes. In an alternative embodiment of the present utility model, each of the through holes is a circular hole. In an alternative embodiment of the utility model, the engagement strap is adapted to pass through a pair of through holes simultaneously to constrain one end of the loop engagement strap to the barrier portion, and The other end of the engagement strap is adapted to be secured to a side of the glenoid backplate facing the glenoid bulb. In an alternative embodiment of the utility model, the belt loop titanium plate is connected to the loop coil by a loop connection. In an alternative embodiment of the utility model, the belt loop titanium plate comprises a plate-like body and a pair of adjacently arranged perforations provided on the plate-like body and a partition located between the pair of perforations; the annular connecting wire is adapted to pass through a pair of perforations simultaneously to restrain one end of the annular connecting wire to the partition. The artificial shoulder joint prosthesis component has the advantages that the artificial shoulder joint prosthesis component can be fixed on the scapula in a wire band mode through improvement and optimization of the structure of the shoulder pelvis to replace a screw fastening shoulder pelvis mode in the prior art, the wire band is matched with a belt loop titanium plate and can be hung on the other side of bone to achieve fixation, the problems that when the artificial shoulder joint is installed, components on the shoulder pelvis side are difficult to install, screws are separated out and the fixation is unstable due to the traditional structure are avoided, and the like.
