Problems solved by technology

In the traditional operation, the doctor can only complete the locking of the distal end of the intramedullary nail with the help of C-arm X-ray perspective, which not only requires long-term exposure to X-ray radiation, but also has high requirements for the doctor's experience and skills

Description

technical field [0001] The present invention relates to a medical robot device, specifically, a modular orthopedic robot with a gantry-type single closed-loop parallel structure for assisting the locking of the distal end of the intramedullary nail with miniaturization and modular design . Background technique [0002] At present, the treatment of orthopedic surgery has shifted from traditional closed reduction to minimally invasive surgery. As a typical minimally invasive surgery, intramedullary nailing is gradually becoming the first choice for the treatment of long bone fractures. During the operation, the intramedullary nail is implanted into the bone marrow cavity of the fractured bone, and the proximal and distal ends are respectively locked with screws to fix the fracture. This minimally invasive operation causes less damage to the patient and has a good fixation effect. Conducive to postoperative recovery of patients. This minimally invasive operation requires the ...
