AI Technical Summary
Existing technologies involve long bone harvesting times and significant trauma to patients. Current bone harvesting methods are time-consuming and cause considerable damage to surrounding bone structures.
A bone-harvesting auxiliary structure, including a locator and a bone-breaking guide structure, is used. The locator is placed on the target bone and inserted into the bone using a percussion bearing structure. The bone-breaking guide channel guides the bone-breaking component for bone-breaking operations.
It improves bone harvesting efficiency, shortens bone harvesting time, reduces trauma to patients, and promotes patient recovery.

Abstract
Claims
1. A bone harvest assist structure, characterized by: include: Positioner (1), the positioner (1) includes a positioning cylinder (11) and a striking bearing structure (12) disposed on the upper end of the positioning cylinder (11), the positioner (1) can be sleeved on the target bone body (10); A bone-breaking guide structure (2) is fixedly disposed on the side of the positioning cylinder (11). The bone-breaking guide structure (2) is provided with a bone-breaking guide channel (21). The outlet of the bone-breaking guide channel (21) is directly opposite the bottom end of the locator (1). The bone-breaking guide channel (21) is used to guide the bone-breaking piece (20) to the bottom end of the locator (1) to break the target bone body (10).
2. The bone harvest assisting structure of claim 1, wherein: It also includes a handle (3), which is disposed on the positioning cylinder (11).
3. The bone harvest assist structure of claim 2, wherein: The fracture guide structure (2) includes the handle (3), and the fracture guide channel (21) passes through the handle (3) and is close to the lower end of the handle (3).
4. The bone harvest assist structure of claim 3, wherein: The handle (3) includes a vertical section (31) arranged parallel to the positioning cylinder (11), and the vertical section (31) has a plurality of grip grooves (311) arranged continuously on the side near the positioning cylinder (11).
5. The bone harvest assist structure of claim 4, wherein: The bone fracture guide channel (21) is perpendicular to the positioning cylinder (11).
6. The bone harvest assisting structure of claim 1, wherein: The impact-bearing structure (12) includes a support plate, which is coaxially arranged with the positioning cylinder (11), and the outer diameter of the support plate is larger than the outer diameter of the positioning cylinder (11).
7. The bone harvest assisting structure of claim 1, wherein: The bottom end of the positioning cylinder (11) is provided with serrations (111) or blades (112).
8. The bone harvest assisting structure of claim 1, wherein: The bone fracture guiding structure (2) includes a connecting rod (22) and a guide tube (23). One end of the connecting rod (22) is connected to the outer wall of the positioning tube (11), and the other end is connected to the guide tube (23). The internal channel of the guide tube (23) is the bone fracture guiding channel (21), and the outlet of the guide tube (23) faces the bottom end of the locator (1).
9. A bone harvesting device, characterized by: Includes the bone harvesting auxiliary structure and bone breaking component (20) as described in any one of claims 1 to 8.
