Parallel robot system for lower limb fracture reduction surgery

Abstract

The invention provides a parallel robot system for lower limb fracture reduction surgery, and belongs to the technical field of fracture reduction. The parallel robot system comprises an annular table, an offset hinge body and a telescopic rod; wherein the annular table is used for fixing a lower limb, and the offset hinge body comprises a first hinge body, a second hinge body and a connecting block; one end of the first hinge body is rotationally connected with one end of the connecting block through a first rotating shaft; the other end of the first hinge body is suitable for being detachably connected with the annular table; one end of the second hinge body is rotationally connected with the other end of the connecting block through a second rotating shaft; wherein the first rotating shaft is perpendicular to the second rotating shaft, and the two ends of the telescopic rod are both suitable for being hinged to the annular table through offset type hinge bodies; the telescopic rod is suitable for being detachably connected with the other end of the second hinge body. The system improves 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 diaphysis fractures and tibial plateau fractures. Fractures of the tibial shaft account for about 29.45% of all fractures in the body, especially in children under the age of 10. About 30 million people in my country suffer from fractures every year, and about 10 million of them suffer from fractures of the tibial shaft. [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 lesions. During the operation, there is always the danger of excessive body movement, which will cause tea...

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.
