Abstract

The invention discloses a hollow spicule and a matched tool thereof, and belongs to the technical field of medical instruments. The hollow spicule comprises a hollow spicule body and an external fixing support, wherein the hollow spicule body is of a hollow columnar structure, the bottom of the hollow spicule body is provided with bone threads and a plurality of side holes for communicating the interior of the hollow spicule body with the outside, and the hollow spicule body is arranged on the external fixing support to be used for fracture fixation. The hollow spicule is of a hollow columnarstructure, positioning can be conducted through guiding of a guide needle, and intraoperative operation is facilitated; and meanwhile, medicine can pass through the hollow spicule body, the bottom ofthe hollow spicule body is provided with the bone threads and the side holes enabling the interior of the hollow spicule body to communicate with the exterior of the hollow spicule body, and the injected medicine flows out through the side holes to reach a fracture part, so that targeted treatment can be carried out on lesions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hollow bone needle and its supporting tools. Background technique [0002] With the development of society and the changes in people's life and work styles, patients with complex extremity fractures caused by high-energy injuries such as falls from heights, car accidents, and loss of motion show diverse characteristics, such as closed fractures combined with compartment syndrome, multiple Fractures, open fractures, fracture wound infections, fracture nonunions, and large bone defects. [0003] At present, for the various fracture situations listed above, it is often difficult to obtain good therapeutic effects by simply using traditional fracture reduction and internal fixation methods, which have high surgical difficulty, many postoperative complications, postoperative infection and internal fixation failure. Many other issues. With the in-depth study of the concept ...
