Abstract
The utility model belongs to the technical field of medical appliance, and in particular relates to a bone implanting instrument for cervical vertebral bodies, which consists of a tail rod and a head end. The upper two thirds of the tail rod is a knurling handle (1), while the lower one third is a polished rod (2); the center of a platform of the head end is provided with a screw stud (3), and an oblong baffle plate (4) is arranged at the position of 1.5 millimeters close to the platform. A bone piece is not easy to fall during the operation, and the bone implanting instrument is convenient and quick to implant, and is favorable for preventing the implanted bone piece from falling and anterior fixation.
Description
Technical field:
This utility model belongs to technical field of medical instruments, is specifically related to a kind of cervical vertebral body inter-planting bone object.
Background technology:
At present, in anterior cervical operation, particularly between cervical vertebral body during bone grafting, there is not special-purpose bone grafting apparatus, generally be directly the bone piece to be put into bone graft area with tweezers, back reuse hammer is squeezed into, and this mode of operation not only makes the easy landing of plant bone mass and pollutes, and being not easy to control the direction that plant bone mass is placed, run-off the straight easily, rotation or bone piece were squeezed into dark or shallow excessively.
The utility model content:
This utility model is at the problems referred to above, and a kind of cervical vertebral body inter-planting bone object is provided.
For achieving the above object, the technical solution of the utility model is: a kind of cervical vertebral body inter-planting bone object, form by foot piece and head end two parts, foot piece on it 2/3rds places be the annular knurl handle, / 3rd places are bright and clean bar down, at head end platform center one double-screw bolt is arranged, platform nearside 1.5mm place is provided with a rectangle baffle plate.
The annular knurl handle 1 of its foot piece of this utility model, be convenient to during use hold steadily, in order to avoid landing, bright and clean bar 2 parts often contact with tissue, avoid increasing tissue injury, the double-screw bolt 3 of head end is in order to connect plant bone mass, bone piece difficult drop-off in operating process, implant convenient and swift, the rectangle baffle plate 4 that head end platform nearside is provided with, when bone grafting, can withstand on Cervical vertebrae pressure-reducing window bone edge surface up and down, play barrier effect, make the bone piece can not cross the window that reduces pressure up to one's neck in, the purpose that head end stretches out 1.5mm is when the impaction bone grafting piece, plant bone mass is sunk to being lower than anterior margin of vertebral body slightly, help preventing that plant bone mass from deviating from preceding road fixes.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
This utility model adopts rustless steel to make.After anterior cervical decompression, accurately measure required bone block size, get suitable bone grafting fast (generally getting the ilium piece), the heart punches in advance with the 2.5mm drill bit therein, then with screw in bone piece in vertical of double-screw bolt 3 of cervical vertebral body inter-planting bone object with the bone piece, make the bone piece near cervical vertebral body inter-planting bone object head end platform, cervical region is hammered plant bone mass into bone graft area into shape gently with cervical vertebral body inter-planting bone object under traction, again cervical vertebral body inter-planting bone object is screwed out, at this moment, as seen plant bone mass is sagging slightly, reaches the purpose that bone grafting is lower than anterior margin of vertebral body slightly.
Claims (1)
- A kind of cervical vertebral body inter-planting bone object, form by foot piece and head end two parts, it is characterized in that: foot piece on it 2/3rds places be annular knurl handle (1), 1/3rd places are bright and clean bar (2) down, at head end platform center one double-screw bolt (3) is arranged, platform nearside 1.5mm place is provided with a rectangle baffle plate (4).
