Embodiment Construction

[0015] The present invention includes a base 1, a gland 2, a reset support rod 3, and a clamping block 13, and these structures can reset tibial plateau fractures in different directions such as up, down, left, and right, respectively.

[0016] As shown in the figure, the base 1 is a cuboid, the upper part of the base 1 has a groove 4, the groove 4 is along the centerline of the width direction of the base 1, and the two ends of the groove 3 are opened on both sides of the base 1. The surface of the groove 3 is arc-shaped, and the radian of the arc-shape matches the shape of the outer periphery of the human body at the lower part of the knee joint. During treatment, the base is placed under the patient's tibial plateau, and the knee joint of the human body is placed on the groove 4 .

[0017] As shown in the figure, the gland 2 is located above the base 1 , and the length and width of the gland 2 match the length and width of the base 1 . There is an upward depression 5 on th...

Abstract

The invention discloses a tibial-plateau fracture resetting device, and belongs to the technical field of orthopedic medical devices. The tibial-plateau fracture resetting device is used for closed state resetting of a tibial-plateau fracture. According to the technical scheme, grooves are formed in the upper portion of a base, the surfaces of the grooves are in circular arc shapes, a pressing cover is located on the base, upward concave parts in the bottom face of the pressing cover correspond to the grooves in the base, the base is connected with the pressing cover through pressing bolts, the middles of two resetting supporting rods are installed in openings in the two sides of the upper portion of the base through rotating shafts, and the front ends of the two resetting supporting rods are opposite at the bottoms of the grooves. Tibias can be pressed and reset from the upper portion and the lower portion through the base and the pressing cover, and pressing and resetting can be further carried out through the resetting supporting rods from the portion below a tibial plateau. The tibial-plateau fracture resetting device initiates tibial-plateau fracture treating, a tibial-plateau fracture block can be reset in the closed state of soft tissues such as the skin and muscle, and the problem that the tibial-plateau fracture can not be satisfactorily reset easily under the minimally invasive condition is solved; the tibial-plateau fracture resetting device has the advantages of being simple in structure, convenient to use and good in resetting effect.

Description

technical field [0001] The invention relates to a device for resetting tibial plateau fractures, which belongs to the technical field of orthopedic medical devices. Background technique [0002] Tibial plateau fractures mostly occur in high-energy trauma, such as falling from heights, car accidents, and falls. As the tibial plateau is an important load-bearing structure of the lower limbs, when it is subjected to severe vertical, varus, and valgus violence, it often causes bone structure damage, often manifested as split fractures of the tibial plateau, with or without articular surface collapse, and severe Some patients even have knee joint dislocation and metaphyseal comminution. The soft tissues around the knee joint and joint stabilizing structures (medial and lateral collateral ligaments, menisci and cruciate ligaments) will also be affected. Therefore, the treatment of tibial plateau fractures has always been a hot and difficult point in trauma orthopedics. With the...
