A parallel robot system for lower extremity fracture reduction surgery

Abstract

The invention provides a parallel robot system for lower limb fracture reduction surgery, which belongs to the technical field of fracture reduction. The parallel robot system for lower extremity fracture reduction surgery includes a ring platform, an offset hinge body and a telescopic rod. The ring platform is used to fix the lower limbs. The offset hinge body includes a first hinge body, a second hinge body and a connecting block. One end of a hinge body and one end of the connecting block are rotatably connected through the first rotating shaft, the other end of the first hinge body is suitable for detachable connection with the ring platform, and one end of the second hinge body and the other end of the connecting block are rotated through the second rotating shaft Connection, wherein the first rotating shaft is perpendicular to the second rotating shaft, both ends of the telescopic rod are suitable for hinged connection with the ring platform through the offset hinge body, wherein the telescopic rod is suitable for detachable connection with the other end of the second hinge body. Improve the success rate of fracture reduction surgery.

Description

technical field [0001] The invention relates to the technical field of fracture reduction, in particular to a parallel robot system for lower limb fracture reduction surgery. Background technique [0002] Tibial fractures include tibial shaft fractures and tibial plateau fractures. Tibial diaphysis fractures account for about 29.45% of all body fractures, especially in children under the age of 10. About 30 million people in my country suffer from fracture trauma every year, of which about 10 million suffer from tibial diaphysis fractures. [0003] Traditional fracture reduction surgery requires two doctors to first pull the muscles, and then use X-rays and other images to achieve reduction and alignment. Because doctors need to be exposed to X-rays for a long time to work, it is very unfavorable for doctors' health and easy to induce. cancerous lesions. During the operation, there is always the danger of excessive movement of the body, resulting in tearing of muscles, tis...

AI Technical Summary

Problems solved by technology

[0003] Traditional fracture reduction surgery requires two doctors to first pull the muscles, and then use X-rays and other images to realize the reset and straightening work. Because doctors need to work under X-rays for a long time, it is very unfavorable to the health of doctors, and it is easy to induce cancerous lesion

During the operation, there is always the danger of excessive body movement, which will cause tearing of muscles, tissues and ligaments, resulting in unsatisfactory post-reduction results, and the surgical effect varies greatly depending on the skill level of doctors. Difficult to guarantee, so less homogeneity

In addition, the operating precision of the human hand is much lower than that of the robot, and it may be difficult for the surgeon to perform fine adjustment and maintenance under large forces and torques in traditional reset techniques.
