The automatic screw twisting device is characterized in that the screws and the bone connecting plates can be synchronously fixed by operating the device in a handheld manner, therefore, the automatic operation is realized, the surgical process is simplified, and the surgical efficiency is improved.
Description
Technical field
The present invention relates to the most stubborn spike devices of a kind of surgery, be mainly used in screw and bone in surgical operation and connect
Fixing of sheet, it is achieved screw and bone are connected sheet synchronization, rapid fixing effect, belongs to surgical technic field.
Background technology
The field relating to bone fixing includes neurosurgery, decorative sursery, cardiothoracic surgery, orthopaedics etc., and such as neurosurgery is opened
Cranium operations etc., can relate to also receiving and fixation problem of post-surgery skull, and originally skull connects and relies primarily on silk thread and fix, return by
Gradually occur in that the mode that skull lock is fixing, i.e. skull is pinned from intracranial by two pieces of metal disks of application, plays fixation, but
There is the risk of postoperative generation epidural hematoma in this mode, in the way of skull is fixed and can be fixed to use bone connection sheet later,
I.e. outside skull, free osseous flap is connected sheet is fixed with Peripheral Bone edge application nail and bone, it is usually required mainly for apply manual spiral shell
Silk cutter first will at least three pieces of connections after sheet screws are fixed on free osseous flap, skull is also received, after reapply hand screwdriver
Being fixed on Peripheral Bone edge by the connection sheet other end, operating process is relatively complicated.Additionally decorative sursery wound or surgical patient are also
Needing to repair maxillofacial bone bone and profile, relate to the fixing of skeleton, cardiothoracic surgery Thorax operration chest rib is also received to be needed to connect sheet
Fixing, the operation of orthopaedics majority all refers to the problem that Postoperative Bone is fixing, currently mainly mode and still connects sheet for application titanium alloy bone, and
Application screw is fixed in the mode within osseous tissue.
At present, surgery skeletal fixation both domestic and external and repairing enterprise, such as: Medtronic Inc. of the U.S., Germany's shellfish bright Serpentis board
The stubborn nail mode of company, pungent DIS of Switzerland etc. is manual screw blade, and its operating process mainly, connects by one piece of bone
Sheet, takes one piece of screw the most again, uses hand screwdriver by screw by connecting the preformed hole on sheet by screw during operation
Nail is fixed on bone edge, is required to reinstall another piece of screw after fixing at one every time, needs doctor to incite somebody to action during this
Screwdriver passes to instrument nurse, and instrument nurse installs one piece of screw to screwdriver head end, operates passing to doctor,
Further taking out other one piece of connection sheet after should being finished one piece of connection sheet to be fixed, operating process is relatively complicated, and continuity of operation is not
By force, the workload of doctors and nurses is relatively big, and in operation due to screw small volume, quality is lighter, it is easy to come off
In art district or other relative bacteria districts, the most easily it is attracted device simultaneously and inhales by mistake, reduce procedure efficiency, affect procedure.
Neurosurgery partial surgical is sphenotresia operation, such as: EVD, intracranial hematoma trepanation and drainage etc., with
And when operation of opening cranium, need to apply electric drill to bore 1 and arrive several pieces of bone hole, then carry out separating bone flap operation, postoperative due to bore position
Osseous tissue lacks, and especially at operative sites such as frons, bone hole can affect patient's forehead outward appearance, and patient self cenesthesia is not
The problem such as suitable, mode primarily now is fixed at bone hole with skull lock, or application skull closure titanium plate solves the problems referred to above,
But the most described skull lock is easily caused epidural hematoma, and blocks the fixing of titanium plate and need many pieces of Reusability
The fixing operation of screw, operating process is relatively complicated, and the time is longer, and is in local anaesthesia state at part boring patient during operation,
Longer operation time can cause patient more nervous, and local anaesthesia medicine anaesthetic effect goes down, and even occurs that cardiovascular and cerebrovascular vessel are also
Sending out disease, have an intense pain equally likely possibility.
Summary of the invention
For the problems referred to above of the prior art, it is an object of the invention to provide one can connect sheet by screw and bone
