Technical Field

The application relates to a surgical operation, in particular to a bone tilting special for osteotomy.

Background

In the surgical operation, when a doctor cuts a bone, the angle direction of the cut bone cannot be accurately grasped.

Disclosure of Invention

The invention aims to provide a bone raiser special for osteotomy.

In order to achieve the above object, the present invention provides the following technical solutions.

The embodiment of the application discloses special bone of cutting bone sticks up, fly leaf and fixed plate including relative laminating slip setting from top to bottom, the fly leaf is along its extending direction slidable mounting in the fixed plate, the fly leaf front end is the protruding first arc that is formed with of stretching upwards, the fixed plate front end is the protruding second arc that is formed with of stretching upwards, be formed with the double-layered mouth of centre gripping bone between first arc and the second arc, pass through the bolt fastening between fly leaf and the fixed plate, first arc plate surface is formed with the electric saw groove, second arc plate surface is formed with perspective hole.

Preferably, in the osteotomy-specific tilted bone, the first arc-shaped plate bottom surface is attached to the bone.

Preferably, in the osteotomy-specific tilted bone, the top surface of the second arc-shaped plate is attached to the bone.

Preferably, in the osteotomy-dedicated bone lifter, a portion of the fixing plate between the first arc-shaped plate and the second arc-shaped plate is attached to a bone.

Preferably, in the above bone tilting for osteotomy, the movable plate and the fixed plate are respectively formed with arc-shaped sections attached to each other at the middle portions thereof.

Preferably, in the above bone lifter for osteotomy, a screw hole through which the bolt passes is formed on a surface of the movable plate, and an elongated slot through which the bolt slides is formed on a surface of the fixed plate.

Preferably, in the osteotomy-specific bone raiser described above, the bolt is provided in 2 pieces.

Compared with the prior art, the movable plate can slide back and forth on the fixed plate in the technical scheme so as to ensure that the size of the clamping opening can be just covered on the bone (a tibial plateau); when the movable plate moves forwards and backwards to reach a proper position, the fixing screw is screwed, the C-arm machine irradiates, and a proper osteotomy line is determined through the perspective hole on the fixed plate and the electric saw groove on the movable plate; the electric saw begins to cut bones along the electric saw groove of the movable plate, and at the moment, the bone cutting position and the direction have no deviation.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-4, the bone lifter 100 for osteotomy includes a movable plate 101 and a fixed plate 102, which are slidably attached to each other in an up-down direction, the movable plate 101 is slidably mounted on the fixed plate 102 along an extending direction thereof, a first arc-shaped plate 103 is formed at a front end of the movable plate 101 in an upward protruding manner, a second arc-shaped plate 104 is formed at a front end of the fixed plate 102 in an upward protruding manner, a bone clamping opening 105 is formed between the first arc-shaped plate 103 and the second arc-shaped plate 104, the movable plate 101 and the fixed plate 102 are fixed by 2 bolts 106, an electric saw groove 107 is formed on a surface of the first arc-shaped plate 103, and a perspective hole 108 is formed on a surface of the second arc-. The first arcuate plate 103 is attached to the bone at its bottom surface. The second arcuate plate 104 is top-fitted to the bone. The portion of the fixation plate 102 between the first arcuate plate 103 and the second arcuate plate 104 conforms to the bone. The movable plate 101 and the fixed plate 102 are respectively formed with arc-shaped sections 109 at the middle portions thereof, which are attached to each other. The movable plate 101 has a screw hole 110 formed on a surface thereof for passing the bolt 106 therethrough, and the fixed plate 102 has a long groove 111 formed on a surface thereof for sliding the bolt 106 therethrough.
