Description
Technical field
The present invention relates to a kind of medical drag hooks, in particular to are not necessarily to the light-guiding retractor of external light source.
Background technique
In surgical operation, traction opens tissue and exposes surgical field of view, and the light in surgical field of view area is for operator
Very important, good surgical field of view is to ensure that the prerequisite that operation is gone on smoothly.When surgical field of view area insufficient light,
Operator is often through the angle for adjusting top shadowless lamp, in the hope of obtaining satisfied visual effect.And small to bore face to face, lacuna
When deeper operative site, repeatedly adjustment shadowless lamp is generally required frequently, the process of operation is largely effected on, is even influenced when serious
To the success or failure of operation.
Existing Medical light-guiding retractor, it usually needs power supply, external high power light source, guide-lighting rope etc..However this leaded light
Drag hook has a variety of defects, and the first power volume is larger, the second guide-lighting rope frangibility and non-refractory, postoperative surgical instrument high temperature
Disinfection can seriously affect its life and reliability.Chinese patent literature CN200520081170.3 discloses a kind of Medical light-guiding
Drag hook, using high brightness (nitride) light emitting diode as cold light source to operation field of vision illumination, its shortcoming is that needing outer
Power supply is connect, can just make LED lighting, extraneous power supply is inconvenient and will increase the volume of auxiliary lighting system, postoperative high-temperature sterilization meeting
The service life of the light emitting diode and power supply is had an impact, auxiliary lighting system is directly damaged when serious, is used for a long time
Easy failure, reliability substantially reduce afterwards, and consequence is extremely serious if breaking down in operation.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of light-guiding retractor without external light source, is drawn in operation using the leaded light
Hook carries out floor light to operation field of vision, without frequently adjusting shadowless lamp, the Surgery especially suitable for bore lacunula depth
Position, and the light-guiding retractor is not necessarily to power supply, small in size, not easy to break, high temperature resistant can be with postoperative high-temperature sterilization, long-time use reliability
It is good.
The present invention is technical solution in this way to realize, a kind of light-guiding retractor without external light source, comprising:
Beam condensing unit, the beam condensing unit are a convex lens with cylindrical housings, are converged to external light, are collected
Optical signal；
Astigmatism device, the astigmatism device are the concavees lens with cylindrical housings, are dissipated the light converged to,
Enhance visual area light；
Light transmitting device, the light transmitting device are one section of optical cable；
Drag hook main body, the drag hook main body are the pull device of tissue in operation；
The beam condensing unit is connect with one end of the light transmitting device, the astigmatism device and the light transmitting device
Other end connection, the beam condensing unit, the light transmitting device, astigmatism device composition auxiliary light-conducting system, in the drawing
Guide channel is set in hook main body, the light transmitting device is fixed in the guide channel；
Diametrically a pillar, the two pillars are respectively arranged in two extended ends to the convex lens mirror surface one of the beam condensing unit
It is embedded in the cylindrical housings of the beam condensing unit, to be fixed, to keep convex lens free along the axis where the diameter
Rotation obtains suitable light source input to adjust the direction of convex lens mirror surface.
Further, the optical cable of the light transmitting device, is made of strengthening core and cable core, sheath, outer jacket part, tool
There is the anti-folding characteristic of good tension, the refractive index of inner core is greater than the refractive index of housing, therefore " total reflection " can be utilized light
It is transmitted in channel interior orientation, light loss consumption is few.
Further, the light transmitting device is the optical cable of high temperature resistant material, it is the convex lens of the beam condensing unit, described
The concavees lens mirror body of astigmatism device is pyroceram material, and shell is high-temperature resistance plastice.
This light-guiding retractor without external light source provided by the invention due to the above structure, especially suitable for
The operative site surgical field of view of bore lacunula depth illuminates, and when insufficient light replaces greater area of beam condensing unit convex lens, with
And the measures such as adjusting convex lens direction alignment light source can improve the illumination in surgical field of view area, small in size, not easy to break, resistance to height
Temperature can with postoperative high-temperature sterilization, the auxiliary light-conducting system of the light-guiding retractor can in conjunction with multiple types or the drag hook of shape, and
Without external power supply or cold light source, directly the light of operating room shadowless lamp can be collected, and pass through light transmitting device
" total reflection " effect enhances drag hook body front end surgical field of view area light, therefore is not easy failure to complete the directional transmissions of light
And damage, it is high using rear reliability for a long time, using simplicity, and can be especially suitable in conjunction with various forms of drag hook main bodys
The operation deeper for bore.
