Description
Technical field
The invention belongs to medical orthopedic instrument technical field, it relates to the taking-up instrument of a kind of memorial alloy encircling type clavicle bone fracture device.
Background technology
In bone surgery, normal use memorial alloy encircling type clavicle bone fracture device to process clavicular fracture, but due to memorial alloy encircling type clavicle bone fracture device structure special, doctor's difficulty when taking out clavicle bone fracture device is big. Therefore the taking-up instrument of memorial alloy encircling type clavicle bone fracture device plays an important role. At present, conventional memorial alloy encircling type clavicle bone fracture device takes out instrument has Special withdrawing forceps, distraction forcep etc., but these take out instruments in surgical procedure not only in-convenience in use, and efficiency is low; In addition, if taking out memorial alloy encircling type clavicle bone fracture device with the instrument such as Special withdrawing forceps or distraction forcep; That will first support out bone fracture device one end encircles arm, then goes to support out encircling arm and could it being taken out completely of the other end, so just likely support unblank the bone bone fracture device the other end when encircling arm before that one end of supportting out encircle arm and will recover. Taking-up is not easy, and brings very big difficulty to operation; Very big misery is brought to patient; Also a lot of inconvenience is brought to doctor.
Summary of the invention
Technical problem to be solved by this invention provides one to save operating time greatly for shortcoming of the prior art, operation technique simplicity, easily memorial alloy encircling type clavicle bone fracture device is made to take out instrument, when the present invention takes out clavicle bone fracture device, two ends are supportted out simultaneously, once just can take out.
Following technical scheme is adopted for solving the technical problem of the present invention:
A kind of memorial alloy encircling type clavicle bone fracture device takes out instrument, comprise support, described support comprises the left support and right support that connect by screw thread axle, the described lower end of screw thread axle is provided with boss, described left support and right support are sleeved on outside screw thread axle, described left support and right support both sides are symmetrical arranged taking-up hook by bearing pin, between described taking-up hook and support, torsion spring is set, described screw thread axle upper outside is provided with the screw thread of dextrorotation, described screw thread axle hollow and inside are provided with left-handed square thread, described screw thread axle upper outside is connected with casing threads, in described sleeve pipe, suit revolves bar, the described lower end of bar that revolves is threaded with screw thread axle inner rectangular screw thread, the described lower end of bar that revolves connects left pressing plate and right pressing plate, described left pressing plate and right pressing plate lay respectively at below left support and right support, described left pressing plate and right pressing plate are flexibly connected.
Described revolve bar upper end arrange revolve bar handle.
Described sleeve upper end arranges sleeve pipe handle.
Memorial alloy encircling type clavicle bone fracture device of the present invention takes out the medical orthopaedics utensil that instrument belongs to a kind of stainless steel. The memorial alloy encircling type clavicle bone fracture device advantage of the present invention is that structure is simple, micro-deformation may be there is in the straight type clavicle bone fracture device of memorial alloy encircling type after human body implants for some time, left and right support and left and right pressing plate can rotate to an angle along revolving bar axle, to be applicable to curved and straight type clavicle, the problem not easily taken out after solving bone fracture device generation micro-deformation, convenient and practical. A set of instrument just can solve the taking-up problem of memorial alloy encircling type clavicle bone fracture device, in taking-up process steadily, easily, conveniently, safe and reliable when taking out bone fracture device, saves time in operation, reduces the misery of patient. Once just can take out whole encircling type clavicle bone fracture device, operating time is shortened greatly, reduce operation difficulty. Cleaning can be split after art, it is convenient to cleaning-sterilizing and uses again.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
A kind of memorial alloy encircling type clavicle bone fracture device takes out instrument, comprise support, described support comprises the left support 2 and right support 10 that connect by screw thread axle 4 symmetry, left support 2 and right support 10 are adaptive, left support 2 both sides are installed by bearing pin 12 symmetry and are taken out hook 3, take out and install torsion spring 13 between hook 3 and left support 2. Right support 10 both sides are installed by bearing pin 12 symmetry and are taken out hook 3, take out and install torsion spring 13 between hook 3 and right support 10. Screw thread axle 4 lower end outside arranges boss, and left support 2 and right support 10 are sleeved on outside screw thread axle 4. Screw thread axle 4 upper outside is provided with the screw thread of dextrorotation, and screw thread axle 4 hollow and inside are provided with left-handed square thread, and screw thread axle 4 upper outside is threaded with sleeve pipe 5, so that fixing left support 2 and right support 10 are altered vertically, sleeve pipe 5 upper end arranges sleeve pipe handle 7. In sleeve pipe 5, suit revolves bar 6, revolves the setting of bar 6 upper end and revolves bar handle 8. Revolve bar 6 to be threaded with the square thread inside screw thread axle 4, revolve bar 6 times ends and nut 14 is set, left pressing plate 1 and right pressing plate 11 are sleeved on and revolve outside bar 6, and left pressing plate 1 and right pressing plate 11 lay respectively at below left support 2 and right support 10, and left pressing plate 1 and right pressing plate 11 are positioned at above nut 14.
The present invention uses principle: 1) straight type: first rotating on same straight line by left support 2 and right support 10 and left pressing plate 1 and right pressing plate 11, then screw sleeve pipe 5 and screw thread axle 4, sleeve pipe 5 and screw thread axle 4 make left support 2 and right support 10 position fix. The taking-up hook 3 of left support 2 and right support 10 is stuck in the encircling in arm groove of memorial alloy encircling type clavicle bone fracture device. Revolving bar 6 to be threaded with screw thread axle 4 inner rectangular, then bar 6 is revolved in turn, revolves the dynamic left pressing plate 1 of bar 6 times end band and right pressing plate 11 entirety presses down clavicle beam, at this moment takes out hook 3 activity and makes clavicle encircle arm slowly to support out; 2) curved: first by left support 2 and right support 10 and left pressing plate 1 and right pressing plate 11, along revolving, bar 6 axle rotates to an angle, to be applicable to the radian of curved clavicle, then screwing sleeve pipe 5 and screw thread axle 4, sleeve pipe 5 and screw thread axle 4 make left support 2 and right support 10 position fix. That takes out that hook 3 is stuck in memorial alloy encircling type clavicle bone fracture device encircles in arm groove, revolve bar 6 to be threaded with the square thread of screw thread axle 4, then bar 6 is revolved in turn, revolves bar 6 and drives left pressing plate 1 and right pressing plate 11 entirety to press down clavicle beam, at this moment takes out hook 3 activity and makes clavicle encircle arm slowly to support out.
