Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of ultra micro segmental bronchi single-chamber air bag blocking
Guan Jing.
Background technique
Bronchoscope is suitable for doing the observation of the lobe of the lung, Duan Jiya segmental bronchus lesion, biopsy sampling, bacteriology, cytology
It checks, cooperation TV system can photograph, teaching and dynamically recording.Lung cancer is that China's disease incidence and lethality are highest pernicious swollen
Tumor is diagnosed to be lung cancer in the past and already belongs to middle and advanced stage more, and treatment is using lobectomy of lungs as standard art formula, and surgical effect is obvious.With
The application of low-dose spiral CT, people's health consciousness enhancing, the discovery rate of the early stage of lung cancer step up, can be with surgical radical treatment
Early stage of lung cancer patient it is also more and more.Current more and more scholars are using Total thoracoscopy anatomical segmental resection of lung treatment early stage
Lung cancer and the curative effect obtained.But it since lung section dissects complexity, makes a variation more, to reach complete anatomical lung section under thoracoscope
Resection difficulty is larger.Operating procedure is substantially as young as possible along lung section artery and vein blood vessel sheath after isolating lung arteriovenous at present
It is carefully separated to distal end, then isolates segmental bronchi.Target segmental bronchus folder using " atelectasis-wither method " determines lung segment limit after closing
Face.Generally speaking, many bronchoscopes are complicated for operation, some are high to the wound of patient, some show patient affected part unobvious.
In order to solve the shortcomings of the prior art, people have carried out long-term exploration, propose miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of Portable video bronchoscope [200720311957.3], including one long
Tubulose bronchoscope, the bronchoscope are divided into mirror handle and mirror body two parts, and an operation portion is arranged at the top of mirror handle, there is adjusting direction
One big knob and a small knob.The top of operation portion is equipped with the button of aspirating valve.It is connected on the right side of the middle and lower part of mirror handle
One liquid crystal micro display screen.There is a connector to connect cold light source on the left of the middle and lower part of mirror handle.There is an image pickup part in the forefront of mirror body,
Contain ultra-thin and antifog miniature webcam.It is guide-lighting window and suction hole by camera, end is seal glass.
Above scheme solve the problems, such as to a certain extent bronchoscope is complicated for operation, target show obscure it is incomplete,
But the program still remains many deficiencies, for example, due to the structure that do not protected to affected part, to certain hemoptysis patients
Wound it is higher.
