Description
Technical field
The utility model relates to a kind of device of installation and removal, especially a kind of dress convenient for bone nail installation and removal
It sets.
Background technique
Currently, the medical technology in orthopaedics constantly develops, bone is corrected for fracturing or needing, is often passed through
The installation that device is fixed in bone nail is squeezed on bone, after waiting bone healings, is being taken bone nail and fixed device by operation
Out, but exist in existing technology since bone nail length is longer, bone nail position during squeezing into is easy to appear offset, no
Convenient for control, it is easy that bone is caused to damage when squeezing into；When being taken out to bone nail, there is certain length due to bone nail
Degree, it is larger there are being swung when bone nail taking-up, it is easy that surrounding bone is caused to damage, stability is poor.
In conclusion there are bone nails during squeezing into that position is easy to appear offset for the prior art, it is not easy to control, beats
It is fashionable to be easy that bone is caused to damage；It is larger there are being swung when bone nail taking-up when being taken out to bone nail, it is easy to bone
Surrounding causes to damage, the technical problem of stability difference.
Utility model content
The purpose of the utility model is to provide a kind of devices convenient for bone nail installation and removal.
There is the utility model bone nail offset is less prone to during squeezing into, convenient for controlling, amplitude of fluctuation when taking-up
Small, stability is good, avoids the characteristics of damage is caused to bone.
The technical solution of the utility model includes: a kind of device convenient for bone nail installation and removal, includes arc-shaped fixed plate,
Arc-shaped dead plate upper end face is equipped with interior hex slot, is equipped with bone nail groove, the arc-shaped fixed plate other side in arc-shaped fixed plate
Equipped with rotary buckle, the side of arc-shaped fixed plate is connected with arc-shaped movable plate through shaft, is equipped with bone in arc-shaped movable plate
Groove is followed closely, the side of arc-shaped movable plate is equipped with buckle, is equipped with internal screw thread in the bone nail groove.
In device above-mentioned convenient for bone nail installation and removal, the rotary buckle is flexibly connected with buckle.
In device above-mentioned convenient for bone nail installation and removal, the internal screw thread is engaged with external screw thread on bone nail.
In device above-mentioned convenient for bone nail installation and removal, the hex slot is flexibly connected turret drill, turret drill
It is connected with electric drill.
Compared with prior art, the utility model is when squeezing into or taking out bone nail, by the way that bone nail head end is placed on bone nail
In groove, arc-shaped movable plate is rotated, makes arc-shaped movable plate and arc-shaped fixed plate closing, is connected by rotary buckle and buckle
It connects and arc-shaped movable plate is fixed in arc-shaped fixed plate, it is recessed with bone nail in arc-shaped fixed plate that bone nail is stuck in arc-shaped activity
In slot, the external screw thread on bone nail is engaged with internal screw thread on bone nail groove, and hex slot is flexibly connected in arc-shaped dead plate upper end face
Turret drill, turret drill are connected with electric drill, and control electric drill rotation completes bone nail and squeezes into or take out, and the bone nail of realization is being squeezed into
It is less prone to offset in the process, convenient for control, amplitude of fluctuation is small when taking-up, and stability is good, avoids causing to damage to bone.
There is the utility model bone nail offset is less prone to during squeezing into, convenient for controlling, amplitude of fluctuation when taking-up
Small, stability is good, avoids the beneficial effect that damage is caused to bone.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is utility model works schematic diagram.
The label in accompanying drawing is: the arc-shaped fixed plate of 1-, 2- rotary buckle, hex slot in 3-, 4- shaft, 5- bone nail is recessed
Slot, 6- buckle, the arc-shaped movable plate of 7-, 8- electric drill, 9- bone nail, 10- internal screw thread, 11- turret drill.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
Embodiment.It is a kind of convenient for bone nail installation and removal device, constitute as shown in Figure 1-3,
It include arc-shaped fixed plate 1, arc-shaped 1 upper surface of fixed plate is equipped with interior hex slot 3, in arc-shaped fixed plate 1
Equipped with bone nail groove 5, arc-shaped 1 other side of fixed plate is equipped with rotary buckle 2, and the side of arc-shaped fixed plate 1 is connected through shaft 4
There is arc-shaped movable plate 7, bone nail groove 5 is equipped in arc-shaped movable plate 7, the side of arc-shaped movable plate 7 is equipped with buckle 6, institute
Internal screw thread 10 is equipped in the bone nail groove 5 stated.
The rotary buckle 2 is flexibly connected with buckle 6.
The internal screw thread 1 is engaged with external screw thread on bone nail 9.
The interior hex slot 3 is flexibly connected turret drill 11, and turret drill 11 connects electric drill 8.
