Problems solved by technology
[0002] The matching assembly of the existing glenoid and the upper end of the humerus is often used as figure 1 The press-fitting device is completed. Although this structure can press and install the two, it is easy to damage the glenoid product.
[0003] During the use of the press-fitting device, the time for the glenoid to rebound and clamp the upper end of the humerus is too long. Due to its material properties, its ability to rebound to the initial state will be worse, and eventually the two will not be clamped, and the installation will fail;
[0004] Furthermore, the structure of the pressure adapter has the technical problem of difficult alignment during installation of the glenoid and the upper end of the humerus, which also prolongs the installation time.

Embodiment Construction
[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] according to figure 2 , image 3 As shown, a device for installing glenoid products includes: a striking block 1, a vertically arranged slide bar 2, a horizontally arranged connecting rod 3, two vertically arranged guide rods 4, a horizontally arranged The lower pressing block 5 and a horizontally arranged receiving block 6 are arranged; the upper end of the sliding rod 2 passes through the connecting rod 3 and is fixedly connected with the bottom of the hitting block 1, and the lower end of the sliding rod 2 is connected to the bottom of the hitting block 1. The upper end of the lower pressing block 5 is fixedly connected; the left and right sides of the c...

The invention provides a device for installing a glenoid cavity product. The device comprises a striking block, a vertically-arranged sliding rod, a transversely-arranged connecting rod, two vertically-arranged guide rods, a transversely-arranged pressing-down block and a transversely-arranged bearing block; the upper end of the sliding rod penetrates through the connecting rod and then is fixedlyconnected with the bottom of the striking block, and the lower end of the sliding rod is fixedly connected with the upper end of the pressing-down block; and the left side and the right side of the connecting rod are correspondingly connected with the guide rods in a sliding mode, the bottoms of the two sliding rods are fixedly connected with the bearing block, and after the striking block is hammered downwards, the sliding rod drives the connecting rod and the pressing-down block to slide downwards relative to the guide rods and are used for assembling the upper end of a humerus and a glenoid cavity which are arranged on the bearing block. The device has the advantages that the upper end of the humerus and the glenoid cavity are instantaneously installed together, and the technical defects that in the prior art, due to the material of the glenoid cavity and other reasons, the capability of rebounding to an initial state is poor, clamping cannot be achieved, and finally installation fails are overcome.
