Lumbar three-way minimally-invasive retractor

Abstract

The invention belongs to the technical field of medical instruments, and discloses a lumbar three-way minimally-invasive retractor which is provided with a fixed disc. A connecting rod is horizontallywelded inside the fixed disc, and a rotating rod is sleeved inside the connecting rod; a fixed seat is welded to the front end of the rotating rod, and a three-way towing hook is fixedly mounted on the fixed seat through a bolt, the rotating rod at the rear end of the fixed seat is sleeved with a sliding plate, a second adjusting rod is welded to the sliding plate, and a first adjusting rod is welded to the tail end of the rotating rod. The lumbar three-way minimally-invasive retractor is provided with the towing hook applied to a lumbar surgery, and the three-way towing hook is disposed. Compared with a conventional opposite-direction hook, the three-way towing hook has an equal traction force in three directions, which reduces the amount of bleeding of the wound, facilitates the work ofa doctor and reduces a patient's postoperative recovery time. The three-way towing hook can be slidably adjusted, and the position of the three-way towing hook can be adjusted according to differentparts of different patients, which is convenient for the doctor to perform an operation.

AI Technical Summary

Benefits of technology

This new design allows for better control over muscle tension during lumber surgeries compared to existing methods like bracing or other means that have been developed earlier. By having two pairs of rods on each side of the plate instead of just one rod per arm, this system provides more stable support than previous designs while also reducing pressure applied at certain areas around it. Additionally, there may exist multiple ways to make these devices easier to store when they shouldn't use them again after being used once. Overall, this technology improves efficiency and effectiveness in treatments such as Lumbar Spines.

Problems solved by technology

This patented technical solution described by the current state of the art involves making sure that there're no pulling or pushing back against the patient during medical procedures when trying to remove organs like blood vessels through minimally invasive techniques (MIS). However, it has been discovered that certain patients have difficulty with doing these things due to their size limitations.
