Typically, an acetabular reamer consists of a manual handle, an extension rod, and a ball-shaped blade, and is used to remove acetabular cartilage and some bone tissue. The acetabular reamer extension rod is a medical device used in conjunction with the acetabular reamer, primarily for reshaping the physiological acetabulum under power tool drive to achieve a precise, desired shape, facilitating the implantation of the acetabular implant. The acetabular reamer extension rod usually consists of a cutting body and a quick-change component. The cutting body is a dome-shaped thin shell with several irregularly distributed raised cutting edges on its outer surface, each cutting edge accompanied by a chip-receiving hole. The quick-change component is used for fixed connection to the bottom of the cutting body.

[0022] Reference Figure 1-5 An acetabular file connector with a splitting mechanism includes a connector body 1. The connector body 1 includes a fixed end 11. A T-shaped ring seat 12 is fixedly sleeved on the outer wall of the fixed end 11. A connector 4 is inserted into one side of the fixed end 11. A limiting ring 2 is sleeved on the outer wall of the connector 4. The limiting ring 2 and the T-shaped ring seat 12 are threaded together. Multiple auxiliary parts 6 are inserted at equal intervals between the limiting ring 2 and the T-shaped ring seat 12. An acetabular file body 3 is provided on one side of the connector 4. A limiting component 5 is inserted into the connector 4 on one side of the acetabular file body 3.

[0023] It is worth noting that the specific structure, connection method and working principle of the connecting rod body 1 and the acetabular file body 3 are all existing technologies that are currently publicly available on the market, and are not the main technical problems to be solved in this utility model. Therefore, this utility model will not elaborate on them.

[0024] Meanwhile, an auxiliary ring is fixedly fitted on the outer wall of the connector 4 away from the inlet / outlet slide groove, and the outer diameter of the auxiliary ring is not greater than the outer diameter of the T-shaped ring seat 12.

[0025] Furthermore, a cross-shaped fixing member is installed at the bottom of the acetabular file body 3, and an inlet / outlet groove is provided at one end of the connector 4 located at the cross-shaped fixing member. A locking cavity is provided inside the connector 4 located on the side of the inlet / outlet groove and at the cross-shaped fixing member.

[0026] Meanwhile, the limiting component 5 includes a fixing ring, and a limiting plug is fixedly installed at the top of the fixing ring at the inlet and outlet of the slide groove.

[0027] Meanwhile, a locking protrusion is fixedly installed at the bottom center of the connector 4, and a limit slot is opened at the top of the fixed end 11 at the locking protrusion.

[0028] Furthermore, both the limiting ring 2 and the T-shaped ring seat 12 have through holes located at the auxiliary component 6, and limiting blocks are symmetrically installed on both sides of the middle part of the through hole of the limiting ring 2.

[0029] Furthermore, the auxiliary component 6 includes a locking end and a handle end. The handle end is fixedly installed on one side of the locking end, and a limiting ring is fixedly sleeved on the outer wall of the locking end near the handle end. A first auxiliary sliding groove is opened on the other side of the locking end at the limiting block, and an auxiliary cavity is opened inside the locking end at the limiting block.

[0030] Furthermore, a locking groove is provided on one side of the T-shaped ring seat 12 at the limiting ring, the depth of the locking groove is greater than the thickness of the limiting ring, and limiting protrusions are symmetrically installed at both ends of the locking groove of the T-shaped ring seat 12 away from the limiting slot, and the limiting protrusions and the limiting blocks are in a parallel state. Second auxiliary sliding grooves are provided on both sides of the limiting ring at the limiting protrusions, and the first auxiliary sliding groove and the second auxiliary sliding groove are in a parallel state.

[0031] Meanwhile, it is worth noting that when the limiting ring 2 and the T-shaped ring seat 12 are connected by threads, the through hole of the limiting ring 2 is aligned with the through hole of the T-shaped ring seat 12.

[0032] In this embodiment, the present invention uses the connecting piece 4, the limiting component 5, the limiting ring 2, and the T-shaped ring seat 12 of the fixed end 11 to quickly assemble and disassemble the connecting rod body 1 and the acetabular file body 3.

After the threaded connection, the through hole of the limiting ring 2 is aligned with the through hole of the T-shaped ring seat 12. Then, rotate the handle end to align the second auxiliary slide groove with the limiting protrusion. At this time, the first auxiliary slide groove is aligned with the limiting block. Then, insert the locking end into the through hole of the limiting ring 2. Then, rotate the auxiliary part until the second auxiliary slide groove and the limiting protrusion are in an interlaced state. At this time, the limiting protrusion limits the limiting ring.
