Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a tibial plateau plate. Background Art

[0002] The tibia is an important bone in the lower limb of the human body and is a key part that bears gravity and movement load in the lower limb of the human body. The tibial plateau is an important structure connecting the tibia and the femur. When a tibial plateau fracture occurs, a tibial plateau plate is needed to stabilize and maintain the normal anatomical relationship of the fracture fragments.

[0003] The tibial plateau plate is generally made of stainless steel or titanium alloy materials, has high strength and good mechanical properties, and can provide sufficient stability and support force.

[0004] The existing tibial plateau plates are usually in the shape of "T" or "inverted L". Since the upper nail holes are usually uniformly 3 or 4 holes, the number of nail holes cannot be increased or decreased according to clinical needs, and some fracture fragments are often unable to be fixed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tibial plateau plate to solve the above problems.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tibial plateau plate, comprising a plate, on the surface of which a plurality of nail holes are evenly arranged. One end of the plate is fixedly connected with a fixing plate, and the fixing plate is detachably connected with an extension plate; and through holes are formed in both the fixing plate and the extension plate.

[0008] Further, the through holes formed in the fixing plate and the extension plate are evenly arranged along their axial directions.

[0009] Further, the fixing plate is fixedly connected with the plate through an arc-shaped connecting plate; and according to different connection positions of the fixing plate and the plate, the fixing plate is divided into a T-shaped plate and an L-shaped plate.

[0010] Further, a separating plate is connected to the fixing plate, and the extension plate is connected to the fixing plate through the separating plate.

[0011] Further, a separating groove is formed on the surface of the separating plate, and the separating groove is in an inverted triangle shape.

[0012] Further, a connecting device is fixedly connected to the fixing plate, and a fixing device is fixedly connected to the extension plate, and the fixing device is arranged in cooperation with the connecting device;

[0013] Among them, the connecting device includes a connecting plate fixedly connected to the fixing plate, and a connecting rod is provided on the inner wall of the connecting plate;

[0014] The fixing device includes a fixing plate fixedly connected to the extension plate, and a fixing groove is formed on the surface of the fixing plate.

[0015] Furthermore, connecting devices and fixing devices are respectively connected to both ends of the extension plate, and the connecting devices and fixing devices are used to connect between every two extension plates.

[0016] Furthermore, the side of the connecting rod that is clamped with the fixing plate is an arc surface, and the side of the connecting rod that abuts against the fixing groove is a right-angle surface.

[0017] The principle and beneficial effects of the technical solution are as follows:

[0018] (1) When in use, pressure can be applied to the fixing plate and the extension plate respectively, so that the fixing plate and the extension plate transmit the received pressure to the separation plate, causing the separation plate to break according to the separation groove, and separating the separation plate from the fixing plate and the extension plate through the separation groove, achieving the ability to remove the extension plate according to requirements for easy use. The separation groove is set in an inverted triangle shape, which can break the separation plate more easily;

[0019] (2) When it is necessary to adjust the width, insert the fixing plate on one side of the extension plate into the connecting plate, so that the connecting rod in the connecting plate clamps and fixes the fixing plate. The arc surface provided on one side of the connecting rod facilitates inserting the fixing plate into the connecting plate, enabling the fixing groove on the surface of the fixing plate to be adaptively clamped and connected with the connecting rod. The right-angle surface on the other side of the connecting rod restricts the fixing plate after the clamping is completed to prevent the fixing plate from moving and detaching.
