Description

Orthopedic wire guiding device

Technical field

This utility model relates to orthopaedics medical apparatus and instruments, specifically a kind of Orthopedic wire guiding device.

Background technology

Fracture is that the seriality of bone structure ruptures wholly or in part.Patient is often-individual position fracture, and minority is multiple fracture.Bony crepitus can be heard when the typical performance of fracture patient is and occurs that abnormal motion, mobile limbs appear in local deformation, limbs etc. after wound.In addition, wound severe pain, there is the dyskinesia after wound in local swelling, congestion.

Through appropriate process in time, most patient can recover original function, and a few patients can leave over sequela in various degree.The final purpose for the treatment of fracture makes injured limb restore funcitons to greatest extent.Therefore, in fractures, it resets, fixing, these three basic principles of functional exercise are very important.

Wherein, settled principle is: after the reduction of the fracture, and because of instability, easy generation is shifted again, diverse ways therefore will be adopted to be fixed in satisfied position, make it heal gradually.Conventional fixing means has: plintlet, plaster bandage, exterior fixation bracket, traction braking are fixing, and these fixing meanss claim extenal fixation.If fixing by surgical incision steel plate, draw point, intramedullary needle, screw etc., then claim internal fixtion.

Be expert in hospital long bone comminuted fracture open reduction and Kirschner wire fixation time, pulverize osteocomma block with auxiliary the tying up of steel wire, or tie up strip bone grafting when bone grafting; Very difficult around operation during steel wire in operation process, be easily damaged to fracture nerve around, blood vessel and soft tissue, affect union of fracture.Therefore how to realize by steel wire easily around fracture site, reduce the difficult problem damage of peripheral nerve, blood vessel become in fracture operation simultaneously.

Wire introducer can well address this problem, and publication number is that the Chinese patent of CN2836737Y discloses a kind of medical steel wire guiding device, and it adopts clamp handle and jaw structure, steel wire encircling is easily realized, and protects surrounding tissue to greatest extent.

But, existing wire introducer Problems existing mainly: 1) the top head of catheter wire mostly is circular pipe type structure, enter fracture inner time resistance comparatively large, and easily to block; 2) two catheter wire docking are not tight, do not utilize steel wire to connect; 3) complex structure, the precision that impact is overall.

Utility model content

This utility model provides a kind of Orthopedic wire guiding device, and its structure is simple, docking is tight, and can enter organization internal smoothly.

The technical scheme that this utility model specifically adopts is:

A kind of Orthopedic wire guiding device, comprise by the hinged left handle of rotating shaft and right handles, left and right handle is respectively equipped with two conduits, through hole is provided with in conduit, the import of trough type steel wire, steel wire outlet is respectively equipped with outside two conduits, steel wire import and steel wire outlet are communicated with conduit inner via hole, and two catheter tip tube heads are ballhead, the taper platform that two conduit spherical head ends are respectively equipped with bellmouth and mate with bellmouth.

In order to ensure the tight of two catheter tip docking, the middle part between left handle and right handles is provided with dead lock, and it utilizes denture and teeth groove to lock, and medical personnel can no longer firmly to be held with a firm grip handle by hand for a long time.

Preferably, left handle, right handles are formed in one with conduit respectively.

Conveniently steel wire imports, and steel wire enters taper nose end from taper you, and therefore, described taper platform and steel wire import are arranged on same conduit.

Because most people left-handed holds thing, right-hand operated, therefore, the preferred structure of this utility model is: be provided with steel wire import outside the conduit of left handle, namely steel wire import is located at right-hand side, and facilitate the right hand to send into steel wire, left handle conduit spherical head end is provided with taper platform, be provided with steel wire outlet outside the conduit of right handles, right handles conduit spherical head end is provided with bellmouth.

Advantage of the present utility model and beneficial effect are:

1, this utility model catheter tip tube head adopts ballhead, and spherical tube head is round and smooth, is beneficial to conduit and enters inside, smooth when conduit enters simultaneously, can avoid the generation of blockage problem.

2, this utility model adopts taper platform and the bellmouth docking of coupling mutually, and relative to the docking between two conduits, the docking access of pyramidal structure is more smooth, is beneficial to connecting smoothly of steel wire.

3, this utility model adopts dead lock, prevents from producing between two handles mutually moving, and ensures that two conduits docking are tight, and meanwhile, during two conduit docking, because taper platform stretches into bellmouth inside, it allows to produce a certain amount of displacement between conduit.

4, this utility model handle and conduit are formed in one, and ensure handle and conduit at grade, can not offset during docking, and overall precision improves.

Detailed description of the invention

As shown in Figure 1, 2, a kind of Orthopedic wire guiding device, comprise by the hinged left handle 3 of rotating shaft 6 and right handles 8, left and right handle is respectively equipped with conduit 1, handle and conduit 1 are formed in one, and are provided with through hole 4 in conduit 1.Middle part between left handle 3 and right handles 8 is also provided with dead lock 7.Two conduit 1 top tube heads are ballhead 10, the taper platform 9 that two conduit ballhead 10 ends are respectively equipped with bellmouth 11 and mate with bellmouth 11.

As shown in Figure 3,4, be respectively equipped with trough type steel wire import 5, steel wire outlet 2 outside two conduits 1, preferably, steel wire outlet 2 is comparatively large, facilitates sending of steel wire.

Preferably, be provided with steel wire import 5 outside the conduit 1 of left handle 3, namely steel wire import 5 is located at right-hand side, and left handle 3 conduit spherical head end is provided with taper platform 9, and be provided with steel wire outlet 2 outside the conduit 1 of right handles 8, right handles 8 conduit spherical head end is provided with bellmouth 11.

The concrete occupation mode of this utility model:

During use, through skin incision, being close to surface of bone both sides, originally not insert two conduit 1, two conduit 1 tube heads be ballhead 10, makes inserting smoothly of conduit 1.Hold with a firm grip left and right two handles, make taper platform 9 enter bellmouth 11, two conduits 1 dock, locking dead lock 7.Steel wire is imported from steel wire import 5, steel wire postpone conduit 1 inner via hole 4 pass steel wire outlet 2, finally, unclamp dead lock 7, take out two conduits 1.
