Separated bone plates for high tibial osteotomy

Abstract

The invention provides separated bone plates for high tibial osteotomy. The separated bone plates for high tibial osteotomy comprises an upper bone plate and a lower bone plate; a plurality of bone nail holes are formed in the upper bone plate and the lower bone plate; an upper warping plate and a lower warping plate are vertically installed on the same side of the upper bone plate and the same side of the lower bone plate, respectively; hollow telescopic connecting rods on the two sides are fixedly installed on the lower bone plate; piston rings are fixedly installed at the ends, away from the lower bone plate, of the hollow telescopic connecting rods on the two sides; channels in the hollow telescopic connecting rods communicate with a channel formed in the lower bone plate; and threaded hole seats are movably installed in threaded rod grooves. According to the separated bone plates for high tibial osteotomy, the upper bone plate and the lower bone plate are arranged in a separated mode, so that pre-opening of a pin plate and cooperative work of locking pliers are not needed, and adjustability and accuracy of the angle of a tibia seam are guaranteed; meanwhile, in the installation process, medicine can be accurately conveyed into the tibia seam through the lower warping plate so that operation time is shortened with operation difficulty reduced and operation efficiency improved. Moreover, later recovery of the patient is also facilitated.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a detachable bone plate for high tibial osteotomy. Background technique [0002] High tibial osteotomy is an open surgical method for medial knee osteoarthritis. Osteotomy corrects the line of lower limbs and redistributes the stress on the osteoarthritis of the knee to the healthy part of the knee to slow down the knee joint. Degenerative changes of the joints, thus facilitating the treatment of osteoarthritis with malalignment. [0003] In the prior art, the application number is "CN201480077986.0", a fixation device for open high tibial osteotomy, including a fixation plate, which includes a head and an elongated plate, and the head forms a plurality of screws holes, the elongated plate is provided with a plurality of screw holes and long holes and is formed protruding from the head side; screws, which are combined with the screw holes; and spacers, which c...

AI Technical Summary

Problems solved by technology

[0004] But above-mentioned this open type high tibial osteotomy still has comparatively obvious defective in use: 1, the bone plate that existing high tibial osteotomy uses is consistent with above-mentioned device, is all integrated settings, in operation During the process, the cut tibial suture needs to be stretched through the pin plate, and after being stretched to a preset angle, the locking forceps is extended into the bone suture to maintain the angle, and the pin plate is withdrawn, and then The installation of the bone plate, and during the installation process, the locking forceps need to ensure that the angle of the tibial suture remains unchanged until the bone plate is installed, and the angle of the tibial suture directly determines the line of force of the patient's lower limbs. If the locking forceps shifts, it will It will lead to an unsatisfactory angle after the bone plate is installed, and the locking forceps limit the rapid installation of the bone plate; 2. The function of the above-mentioned device is relatively single, and it can only fix the tibia, and cannot perform accurate drug delivery during the installation process
