Abstract
The utility model relates to a medical equipment, particularly a femur front ankle bone cutting positioner used in the displacing operation on the surface of the knee joint. The utility model is mainly composed of a femur cortex fixing seat and a cut bone indicating transverse rod, and can ensure that the bone cut gap in front of the femur front ankle bone cutting positioner is in the same plane with the femur cortex fixing seat to cut the bone of the femur front ankle successfully at one time, and the cut surface of the bone is still connected with the femur cortex without being too deep or too shallow.
Description
This utility model relates to a kind of medical apparatus and instruments, especially a kind of femur preartis osteotomy localizer that is used for knee joint surface replacement operation usefulness.
The full knee joint operating theater instruments of present domestic use is the import apparatus, be only applicable to the import knee joint, cost an arm and a leg, be tens times of homemade artificial knee joint price, and external apparatus parts a lot (every cover 3～4 casees), complex operation, and many steps still need operator to estimate adjustment, grasp badly, the same can cause osteotomy inaccurate.Though the present domestic artificial knee joint of several types that has lacks supporting operating theater instruments, so that affects the treatment and wide popularization and application.
It is a kind of simple and reasonable that the purpose of this utility model is to provide, can accurately indicate femur preartis osteotomy, and can with the complete supporting femur preartis osteotomy localizer of homemade artificial knee joint, owing to adopted this device, the Rhizoma Atractylodis Macrocephalae operation is very easy to,, and can guarantees once deep putting in place human body wound minimum, unlikely mistake is dark or shallow excessively, thereby can obtain best surgical effect.
The purpose of wood utility model is achieved in that femur preartis osteotomy localizer is made up of with reservation and osteotomy indication transverse slat femoral cortex.Described femoral cortex holder front end is connected with 2 osteotomy indication transverse slats by the bolt that can wither, and there is a hole lower end of adjustable bolt, is inserted with the place ahead locking pin in the hole; On the described femoral cortex holder rear end face handle is installed, fixedly spine is installed on the back bottom surface; Described fixedly spine is three at least; Described femoral cortex holder front end is provided with a gathering sill.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is user mode figure of the present utility model.
Fig. 3 is an osteotomy sketch map of the present utility model.
Among the figure: 1, femoral cortex holder; 2, hands handle; 3, osteotomy indication transverse slat; 4, adjustable bolt; 5, gathering sill; 6, the place ahead locking pin; 7, fixing spine.
One handle 2 is installed on femoral cortex holder 1 rear end face, fixing point perverse 7 is installed on the back bottom surface, femoral cortex holder 1 front end is connected with two osteotomy indication transverse slats 3 by adjustable bolt 4, and there is a hole lower end of adjustable bolt 4, is inserted with the place ahead locking pin 6 in the hole; The front end of femoral cortex holder 1 is provided with a gathering sill 5, adjustable bolt 4 can move forward and backward in gathering sill 5, the gap of the osteotomy indication transverse slat 3 in the place ahead and 1 end of femoral cortex holder when guarantee using and fixed pan is deposited on the same horizontal plane, guarantee the once success of femur preartis osteotomy, osteotomy surface is continued mutually with femoral shaft cortex, and unlikely mistake is dark or shallow excessively.At first locate during use with the place ahead locking pin, push handle 2 fixing spine 7 is inserted the femur Intradermal, the gap that mobile adjustable bolt 4 makes osteotomy indication transverse slat 3 and femoral cortex holder 1 baseplane are indicated in the gap of transverse slat 3 saw blade and are stretched into osteotomy on same horizontal plane from the place ahead osteotomy.
