Abstract

The utility model relates to a medical device, especially, orthopedic steel wire introducer. Orthopedic steel wire introducer, including interior pole and outer tube, interior rod cover dress is in the outer tube, and the outer tube upper end sets up an opening, and interior pole bottom has a point hook, and interior pole upper portion sets up a elastic bulge including, the top of pole a sets up ring, elastic bulge can pop out from the opening part. The external diameter of outer bore of pipe and outer tube is unanimous, and the distance that interior pole can make progress the pull -up is unanimous with the distance that the point caught hold of the outer tube bottom with a hook. The utility model has the advantages of the utility model discloses simple structure, reasonable in design. On putting point hook with the steel wire, the ring of peak of the staff portion in pullling, the elastic bulge on pole upper portion pops out from the outer tube centre shedding in making, and the distance of the pull -up because interior pole can make progress and the distance that the point caught hold of the outer tube bottom with a hook are unanimous, and by chance the point hook supported bottom the outer tube this moment, through elastic bulge's fixed action, the fixation with steel wire that locates the point hook.

Description

Orthopedic wire guide device

Technical field

This utility model is related to a kind of medical apparatus, especially a kind of orthopedic wire guide device.

Background technology

Currently for the fracture patient of need steel plate or Steel wire fixation, common periosteal elevator is typically adopted to peel off Wound depth face and the periosteum on opposite, pass steel wire using mosquito forcepss blindness around fracture.Wound opposite peeled off by periosteal elevator Periosteum when, easily damage muscle, blood vessel and the nerve in deep face；Wear steel wire around backbone also easily by the muscle on opposite, blood vessel Stab with nerve, or blood vessel, nerve, muscle are fixed on skeleton, lead to that Post operation limbs are permanently numb, paralysis, very To necrosis.In open fracture patient, also easily damage deep tissue, or antibacterial is brought into deep tissue, cause disease Diffusion.

Utility model content

Problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of orthopedic wire guide device, Can easily paramedical personnel to bone grafting with skeleton cut.

For solving the above problems, the technical solution adopted in the utility model is：Orthopedic wire guide device, including interior bar with outward Pipe, described interior bar is sleeved in outer tube, and outer tube upper end arranges an opening, and interior bar bottom has a sharp hook, interior bar top setting one Elastic bumps, arrange an annulus at the top of interior bar, and described elastic bumps can eject at opening.

Preferably, the internal diameter of outer tube and the external diameter of outer tube are consistent.

Preferably, the distance that the distance that described interior bar can be pulled upwardly is hooked to outer pipe bottom with point is consistent.

The beneficial effects of the utility model are：This utility model structure is simple, reasonable in design.Steel wire is put into sharp hook On, pull the annulus at interior bar top, so that the elastic bumps on interior bar top is ejected from outer tube split shed, because interior bar can pull up The distance that the distance rising is hooked to outer pipe bottom with point is consistent, and now by chance sharp hook arrives to outer pipe bottom, consolidating by elastic bumps It is set for using, to the fixation with steel wire at sharp hook.

Brief description

Fig. 1 is the structural representation of this utility model.

Wherein reference is as follows：

1st, interior bar；2nd, outer tube；3rd, opening；4th, sharp hook；5th, elastic bumps；6th, annulus.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described further：

Orthopedic wire guide device, including interior bar 1 and outer tube 2, described interior bar 1 is sleeved in outer tube 2, and outer tube 2 upper end is arranged One opening 3, interior bar 1 bottom has a sharp hook 4, and interior bar 1 top arranges elastic bumps 5, arranges an annulus at the top of interior bar 1 6, described elastic bumps 5 can eject at opening 3.

The internal diameter of outer tube 2 is consistent with the external diameter of outer tube 2, and the distance that interior bar 1 can be pulled upwardly arrives outer tube 2 bottom with sharp hook 4 Distance consistent.

The beneficial effects of the utility model are：This utility model structure is simple, reasonable in design.Steel wire is put into sharp hook 4 On, pull the annulus 6 at interior bar 1 top, so that the elastic bumps 5 on interior bar 1 top is ejected from outer tube 2 split shed 3, due to interior bar 1 The distance that the distance that can be pulled upwardly arrives outer tube 2 bottom with sharp hook 4 is consistent, and now by chance sharp hook 4 arrives to outer tube 2 bottom, passes through The fixation of elastic bumps 5, to the fixation with steel wire at sharp hook 4.

The structure of the elastic bumps 5 in this utility model, application in the prior art has a lot.Such as in interior bar 1 Upper setting one spring, spring arranges elastic bumps 5, and the diameter of elastic bumps 5 is less than the width of opening 3 at outer tube 2.

The above, be only preferred embodiment of the present utility model, is not to make other forms to this utility model Restriction.Any those skilled in the art are changed or are modified as being equal to possibly also with the technology contents of the disclosure above The Equivalent embodiments of change.But every without departing from technical solutions of the utility model content, according to construction of the present utility model and Any simple modification, equivalent variations and remodeling that operation principle is made to above example, still fall within this utility model technical side The protection domain of case.

Claims

1. orthopedic wire guide device it is characterised in that：Including interior bar and outer tube, described interior bar is sleeved in outer tube, outer tube upper end One opening is set, and interior bar bottom has a sharp hook, interior bar top arranges elastic bumps, arranges an annulus at the top of interior bar, Described elastic bumps can eject at opening.

2. orthopedic wire guide device according to claim 1 it is characterised in that：The external diameter one of the internal diameter of outer tube and outer tube Cause.

3. orthopedic wire guide device according to claim 1 it is characterised in that：The distance that described interior bar can be pulled upwardly with The distance that point is hooked to outer pipe bottom is consistent.
