AI Technical Summary

Benefits of technology

This new device helps create accurate alignment between an artificial joint (anterior Crucible Ligaments) implanted into one's knees or legs during surgery. It uses a reduction gear system for precise placement of this prosthetic component within its intended location without requiring extra tools like drills or screwdrivers. Additionally, it includes guiding through holes at different positions along the length of the leg-plate assembly, allowing for easier removal from the patient after healing. Overall, these technical features improve the accuracy and reliance of orthopedic procedures used to replace damaged natural tendons.

Problems solved by technology

This patented technical problem addressed in this patents relates to reducing difficulties with treating periarthritis-related knees caused by osteoporotic compression syndrome (OCS). Current methods involve removing damaged parts from the affected area through surgery, but these procedures are time-consuming and may cause complications like damage to surrounding structures that can be associated with painful recovery for patients during rehabilitation periods after injury.

Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-3 As shown, the present invention discloses a tibial plateau reducer, which includes a positioning arm, a locking module and a reset module. The positioning arm 1 is arc-shaped, that is, the central angle corresponding to the positioning arm 1 is greater than 180 degrees. The inner surface of the head end of the positioning arm 1 is provided with a clamping and fixing plane 1.1. The clamping and fixing plane 1.1 is used to contact the collapsed fracture site on the tibial plateau in clinical operations. Since the clamping and fixing plane 1.1 is designed as a plane structure, the bone block can be prevented from being excessively reset by compressing the plane. Or by visual inspection, the reset pusher 3.2 can accurate

Abstract

The invention provides a tibial plateau repositor. The repositor comprises a positioning arm, a locking module and a reset module, the positioning arm is in a major arc shape, and a clamping and fixing plane is arranged on the inner surface of the head end of the positioning arm; and the locking module is arranged at the position, close to the middle, of the positioning arm, the locking module comprises a fixed installation block and a fixed needle, the fixed installation block is installed on the positioning arm, the reset module is arranged at the position, close to the tail end, of the positioning arm, the reset module comprises a reset installation block and a reset ejector, and the reset installation block is installed on the positioning arm and can be adjusted and locked in a slidingmode along the positioning arm. A collapsed bone block can be accurately positioned under an arthroscope, the whole of collapsed fracture can be lifted and reset through uniform force exertion of a large contact surface, and effective fixation is facilitated.
