Problems solved by technology

[0003] At present, when the single-arm orbital external fixator is used clinically for the treatment of bone defects, the transmission distance of the lateral mass of the external fixator is limited to a certain extent.
Moreover, due to the configuration of its structure, the lengths of the two lateral masses are 6.8cm and 5.8cm respectively, so that in the treatment of bone defects, the maximum space advantage of the external fixator cannot be exerted and the treatment time is prolonged.

Abstract

The invention relates to the technical field of medical instruments, and provides to a single arm outer fixation frame. The single arm outer fixation frame comprises a sliding rod, sliding blocks andextending rods; fixing blocks are arranged at the two ends of the sliding rod respectively, and the sliding blocks are in slide connection with the sliding rod and located between the two fixing blocks; one extending rod is connected to each fixing block, one end of each extending rod is connected with the corresponding fixing block, and the other end of each extending rod is fixedly connected with one sliding block. Bone spicule holes are formed in the two sides of the sliding blocks and the two sides of the fixing blocks, the sliding blocks slide along the sliding rod, and the length of theextending rods can be adjusted to change the position of the bone spicule holes. According to the single arm outer fixation frame, the bone spicule position can be adjusted flexibly, and adjustment quantity is more accurate, which is beneficial for promoting bone growth and union in bone loss treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a single-arm external fixator. Background technique [0002] The single-arm external fixator is used in the treatment of bone defects to fix the position of the bone. [0003] At present, when a single-arm orbital external fixator is used clinically for the treatment of bone defects, the transmission distance of the lateral mass of the external fixator is limited to a certain extent. Moreover, due to the setting of its structure, the lengths of the two lateral masses are 6.8 cm and 5.8 cm, respectively, so that it cannot give full play to the maximum space advantage of the external fixator in the treatment of bone defects and prolong the treatment time. [0004] In view of this, a single-arm external fixator is designed and manufactured, which can flexibly adjust the position between the bone needles, adapt to the growth and healing of bones, and is easy to adjust and hi...
