Preferably, described single condyle displacement Tibial osteotomy protector also comprises holds handle, and described matrix comprises the second end, and described holds handle comprises the first end and the second end, and described the second end connects the first end of described holds handle.
More preferably, described the second end and described first end removably connect.
Further, described the second end is connected with described first end clamping.
More preferably, described holds handle is arc, and described second end is away from described stop inserted sheet.
More preferably, described single condyle displacement Tibial osteotomy protector also comprises strike handle, and described strike handle is installed in described second end.
Beneficial effect of the present invention is specifically:
1, single condyle displacement Tibial osteotomy protector of the present invention comprises protection portion, described protection portion comprises matrix and stops inserted sheet, is connected under described stop inserted sheet is positioned at described matrix with described matrix phase; thus by stopping that inserted sheet inserts below Horizontal osteotomy plane; protect when Horizontal osteotomy, prevent many sections, protection patient; stop that inserted sheet can insert spongy bone; do not invade and cortical bone, avoid fissure fracture to occur, design ingenious; simple for structure, be suitable for large-scale promotion application.
2, the two ends of the described matrix of single condyle displacement Tibial osteotomy protector of the present invention protrude from the two ends of described stop inserted sheet respectively; thus the extension design of matrix makes matrix can be supported on cortical bone; avoid and inserted dark and caused spongy bone to cross poly-injury; design ingenious; simple for structure, protect when Horizontal osteotomy, prevent many sections; protection patient, is suitable for large-scale promotion application.
3, the described matrix of single condyle displacement Tibial osteotomy protector of the present invention comprises first end, and described first end is oblique wedging end, convenient insertion; design ingenious, simple for structure, protect when Horizontal osteotomy; prevent many sections, protection patient, is suitable for large-scale promotion application.
Accompanying drawing explanation
Fig. 1 is the schematic front view of a specific embodiment of the present invention.
Fig. 2 is the enlarged diagram of the protection portion of the specific embodiment shown in Fig. 1.
Detailed description of the invention
In order to more clearly understand technology contents of the present invention, describe in detail especially exemplified by following examples.
Refer to shown in Fig. 1 to Fig. 2, single condyle displacement Tibial osteotomy protector of the present invention comprises protection portion 1, and described protection portion 1 comprises matrix 11 and stops inserted sheet 12, and described stop inserted sheet 12 is positioned at described matrix 11 times and is connected with described matrix 11.
Caused spongy bone to cross poly-injury in order to avoid inserting dark, refer to shown in Fig. 1 to Fig. 2, in a particular embodiment of the present invention, the two ends of described matrix 11 protrude from the two ends of described stop inserted sheet 12 respectively.Namely described matrix 11 adopts extension design.
Conveniently insert, refer to shown in Fig. 1 to Fig. 2, in a particular embodiment of the present invention, described matrix 11 comprises first end 13, and described first end 13 is oblique wedging end.
Described oblique wedging end can have any suitable structure, more preferably, the end face of described oblique wedging end is inclined surface or curved surfaces, and described inclined surface or described curved surfaces connect the side of the side of the described dorsad stop inserted sheet 12 of described oblique wedging end and the described stop inserted sheet 12 of connection of described oblique wedging end respectively.Refer to shown in Fig. 1 to Fig. 2, in a particular embodiment of the present invention, the end face of described oblique wedging end is curved surfaces.
For the ease of holding protection portion 1; refer to shown in Fig. 1 to Fig. 2; in a particular embodiment of the present invention; described single condyle displacement Tibial osteotomy protector also comprises holds handle 2; described matrix 11 comprises the second end 14; described holds handle 2 comprises the first end 21 and the second end 22, and described the second end 14 connects the first end 21 of described holds handle 2.
