Description
Technical field
The present invention relates to field of medical appliances, relate in particular to a kind of hand-held video devices being connected with medical endoscope.
Background technology
Endoscope is a kind of for spy on the equipment of interior of articles from outside, is widely used in medical field and industrial circle.Therapeutic medical endoscope is structurally different from industrial endoscope.Industrial endoscope has improved much in traditional endoscope, but therapeutic medical endoscope is limited to its specific object that uses, and its structure has still kept traditional structure.Therapeutic medical endoscope divides hard mirror and soft lens, and hard mirror has conchoscope, peritoneoscope, thoracoscope etc.Hard mirror generally comprises a scope pipe and an outer telescop, the diameter of outer telescop all has from 4 millimeters to tens millimeters, the inside of scope pipe is one group of optical lens, between scope pipe and outer telescop, be one group for the optical fibers of transmission light source, as shown in Figure 1, one end of mirror pipe 01 is the tip stretching in cavity, the other end is provided with a light source interface 02 and an eyepiece portion 03, between eyepiece portion 03, light source interface 02 and mirror pipe 01, be also provided with optical lens, alignment device etc., wherein mirror pipe 01 is inflexible.During use, the tip of endoscope pipe is stretched in cavity, such as being stretches into nasal cavity by nostril, or by abdominal part, open a little operation mouth and stretch into intraperitoneal, doctor sees into the situation in cavitys such as observing nasal cavity, abdominal cavity from eyepiece portion 03.Soft lens has gastroscope, intestinal mirror, branchofiberoscope etc.In the mirror pipe of soft lens, have fibre-optic bundle to carry out leaded light, and lead picture fibre bundle conducting image, because of optical fibers with to lead as fiber be all soft flexible, it is flexible therefore the mirror pipe of soft lens can being made.Soft lens also has eyepiece portion and light source interface, and the inside concrete structure of soft lens is different from the inside concrete structure of hard mirror, but basic conception principle is the same.
Endoscope is used separately, and now, due to the development of technology, existing a set of video system Ke Yu endoscope supports the use.The current endoscope video system using in hospital as shown in Figure 2, comprises a display 04, host computer 06, light source 05 and a photographic head 07.Wherein display, host computer 06 and light source 05 are placed on a Medical trolley 09, and what light source 05 adopted is xenon lamp, and the optical interface of photographic head 07 is connected with the eyepiece portion 03 of endoscope, for passing through the image of endoscope's shot object inside.The video system connecting by Zhe Taoyu endoscope, Ke Jiang endoscope depending on image be amplified on display, make doctor by endoscope, directly observe focus again, simultaneously, cooperation operator also can be understood by display the progress of operation, to coordinate better operation.But what existing this video system adopted is host computer, stand alone display, the bulky equipment of this class of xenon lamp, therefore volume takies more greatly more space on the whole, must use in fixed location, forms also to operation erect-position and tissue simultaneously and hinders.In addition, because display volume is larger, must be away from operating-table, during use, doctor's hand-held camera, observes display, and eye sight line switches back and forth between display and endoscopic procedure position, and eye hands is separated, and easily incoordination, causes malpractice.When doctor needs image that endoscope is spied on to take pictures or record a video, must be assisted by assistant, by assistant's operating computer main frame, realized, very easily because of slow motion half, clap and lose the best opportunity.
In addition, when xenon lamp is connected to the light source interface of endoscope by optical fibers, fiber-optic length is long, even longer two meters of left and right, and the loss that light source causes through optical fibers is thus large especially, affects the brightness that Liao Xiang endoscope provides.In addition, the energy consumption of xenon lamp is large, and the life-span is shorter.
Summary of the invention
