Description
Technical field
The invention belongs to the field of medical instrument technology, specifically a kind of Medical orthopedic operation steel plate broken nail processing instrument
Device.
Background technology
With the development of orthopaedic technique, clinically usually using screw fit steel plate to fixed in fracture site progress,
When taking steel plate and screw, because there are screw thread locking systems between steel plate and screw, along with a variety of causes, the spiral shell such as the problem of getting rusty
Nail fracture, stripped thread keep clinician normal the problem of cannot smoothly removing steel plate, take out screw, orthopedist is enabled to be difficult to avoid
Sense is difficult.Have to carry out reaming, fluting to screw way to take out remaining screw, not only affects Tissue Blood confession, but also make
Fixed area bone amount is reduced, bone strength lowers, therefore requirement can successfully take out the steel plate of fracture, screw and not cause sclerotin into one
It is current urgent problem that step, which is compromised,.
Currently, most is the part tightly clamped using instruments such as tweezers outside broken nail exposing bone, it is then firmly reversed
Rotate tweezers, broken nail taken out, in the process, can only armrest firmly rotate, pull out outside, can not ensure angle out of strength and firmly big
It is small, and also be easy to cause additional injuries to bone because operating personnel do not have power-assisted to cause to take nail slow；Broken nail taking-up side also
Method is first to be made a hole among broken nail with power drill, and then device for taking out broken nail rotation is entered, the design of device for taking out broken nail surface
For anti-pitch thread, it is therefore desirable to rotation counterclockwise, it can be reversed after action torque is more than the thread friction torque of broken nail
It spins out.
Also occur the technical solution that some orthopaedics take broken nail in the prior art, such as application No. is 201620361911 one
Item Chinese patent discloses a kind of bone surgery broken nail withdrawing device, including handle, vertical supporting rod and fixed clamping device, institute
It states shell to connect by being weldingly connected with connecting rod, and shell is arranged between connecting rod, the vertical supporting rod passes through first with connecting rod
Pin, movable sleeve are fixedly connected with fixing screws, and connecting rod is arranged between vertical supporting rod, the bottom of the vertical supporting rod
It is provided with fixing device and bolt, active force room and the first motor, first motor are provided with below the handle
It is rotatablely connected by the first transmission shaft and first shaft coupling with lead screw, and the first transmission shaft, first shaft coupling and lead screw setting exist
In telescopic device room, the lead screw is closely connect with fixed clamping device by screw thread, and the bottom setting of fixed clamping device
Fix to clamp pawl.Although the technical solution can realize the taking-up to broken nail, which only can be to some
The exposed broken nail outside bone carries out that nail is taken to operate；Moreover, when broken nail is longer, the disposable taking-up of entire screw is required
Torsion is big, be easy to cause screw and is broken in inside bone, makes to take nail process time-consuming and laborious.
The steel plate broken nail process instrumentation in consideration of it, a kind of Medical orthopedic of the present invention is performed the operation, segmentation is taken to long spiro nail
The mode of taking-up can avoid the fracture again of screw, take nail effect good, the scope of application is wider, specifically has the beneficial effect that：
The steel plate broken nail process instrumentation 1. a kind of Medical orthopedic of the present invention is performed the operation, drilling blanking punch of the present invention
Block takes dolly set block and lifting module to cooperate with each other, and long spiro nail can cut into multistage, then by screw one section one section take
Going out, the torsion that often taking-up one is blocked needed for nail is smaller, avoids screw and is broken again, while screw is relatively easy to take out,
Take nail effect good.
The steel plate broken nail process instrumentation 2. a kind of Medical orthopedic of the present invention is performed the operation, the lubrication module are used for drilling
Lubricating fluid is provided when cutting module works to be lubricated, and avoids cutting process medium temperature from rising excessively high, human body is caused not accommodate to bone
It damages；Lubricating fluid can recycle simultaneously, reduce the cost used.
The steel plate broken nail process instrumentation 3. a kind of Medical orthopedic of the present invention is performed the operation, the drilling cutting module with take nail
Module is located at the both sides of lifting module, and lifting module can exchange drilling cutting module and take the position of dolly set block, to ensure
It takes dolly set block and drilling cutting module pivot center when being operated to screw to be on same straight line, avoids and bone is made
At injury.
