Description
Technical field
The invention belongs to field of medical technology, and in particular to a kind of minimally invasive locating apparatus for orthopaedics bone-culting operation and
Its localization method.
Background technique
In bone surgery, it usually needs long bone is truncated in specific position, and after needing to be truncated targeted bone the broken ends of fractured bone only at certain
Angulation in one plane to reach therapeutic purposes, while needing on the direction vertical with the plane broken ends of fractured bone not angulation, otherwise can
Generate serious iatrogenic deformity.Traditional operation usually requires completely to expose bone section, and targeted bone, this method wound is truncated in range estimation direction
Greatly, and naked eyes have measurement error, usually fail, it usually needs repeatedly attempt, extend operating time, increase wound, increase operation
Difficulty.
Summary of the invention
The purpose of the present invention is to propose to a kind of minimally invasive bone cutting positioner and its localization methods, can be under the conditions of minimally invasive to osteotomy
Position is accurately positioned, and to facilitate bone-culting operation, and improves the accuracy of bone-culting operation.
Minimally invasive bone cutting positioner of the invention is made of locating piece and the locating rod being connected on locating piece, the locating piece
Both ends be equipped with the through-hole that passes through for Kirschner wire, bottom end and the locating piece of locating rod are connected and fixed, and the top of locating rod is equipped with auxiliary
Help bar, the line for being axially perpendicular to locating piece both ends through-hole of the auxiliary rod.
Localization method using above-mentioned minimally invasive bone cutting positioner includes the following steps:
A: one piece of Kirschner wire is squeezed into the osteotomy site of targeted bone, and guarantees direction and the target of Kirschner wire under C-arm perspective
The long axis of bone is vertical；
B: the through-hole of locating piece one end is covered on the Kirschner wire described in step A, and locating piece is rotated around the Kirschner wire,
Then the position for adjusting locating piece, keeps the line of locating piece both ends through-hole substantially vertical with the long axis of targeted bone, then by locating piece
The second piece of piece of Kirschner wire is squeezed into the through hole of the other end, which is temporarily fixed in targeted bone, to will determine
Position block is temporarily fixed in targeted bone；
C: observing the axial whether parallel with the long axis of targeted bone of the auxiliary rod on locating rod top using C-arm perspective, if
It is not parallel, then step B is re-executed, the position of second piece of Kirschner wire and locating piece is adjusted, if in parallel, by what is be fixed temporarily
Kirschner wire squeezes into whole sclerotin, and the line of two pieces of Kirschner wires is position line, and the position line is vertical with the long axis of targeted bone.
In above-mentioned position fixing process, Primary Location is carried out on narrow minimally invasive face first with two pieces of Kirschner wires, so that
The line of two pieces of Kirschner wires is approximately perpendicular to the long axis of targeted bone, and the auxiliary rod of minimally invasive bone cutting positioner is then recycled to carry out essence
Determine position, it, can be more accurately when being had an X-rayed by C-arm since the length of auxiliary rod is significantly longer than the length of locating piece
The axial whether parallel with the long axis of targeted bone of auxiliary rod checked, if the axial direction of auxiliary rod is parallel with the long axis of targeted bone,
The line (line of i.e. two pieces Kirschner wires) for just representing locating piece both ends through-hole is parallel with the long axis of targeted bone, and it is accurate fixed to realize
Position, doctor can carry out corresponding bone-culting operation according to the line of two pieces of Kirschner wires.
Further, the locating piece and locating rod are detachably connected, and the middle part of the locating piece is equipped with bar shaped recess portion,
The line for being axially parallel to both ends through-hole of the bar shaped recess portion；The bottom end of the locating rod is equipped with and is adapted to the strip-shaped hole
Bar blocks, the axial direction for being axially perpendicular to bar blocks of the auxiliary rod.In the step B, locating piece is temporarily fixed at mesh
After marking on bone, then the bar blocks of locating rod are inserted into the bar shaped recess portion of locating piece, so that locating rod and locating piece be fixed
Connection.
Locating piece is removably connect with locating rod, is conducive to more easily check locating piece both ends in position fixing process
Whether the line of through-hole is vertical with the long axis of targeted bone, and the position for leading to locating piece because of blocking for locating rod is avoided to observe not
Clearly, after to be positioned piece of position substantially determines, then locating rod and locating piece be connected and fixed, it can accurately examined using locating rod
Whether the position for looking into locating piece is accurate.
Minimally invasive bone cutting positioner structure of the invention is simple, and the locating piece using small volume is cutting position progress tentatively
Positioning, recycle longer auxiliary rod to be compared with the long axis of targeted bone and be accurately positioned, thus under the conditions of minimally invasive to cut
The position of bone, which is set, to be accurately positioned, and the accuracy of bone-culting operation is improved.
