In this embodiment, the interface module 13 realizes close circuit connection by five bullet needle modes, passes through buckle
Realize tight structure connection, wherein the interface module 13 includes and shows upper interface that host is connect, connect down with handle
Interface.Upper interface contains five pin plugs, and lower interface contains five needle sockets, all uses gold-plated contact pin, waterproof material.
The display host can be rotated up and down 100 degree, rotate left and right 180 degree, so as to doctor's observation.
Compared with unyielding insertion section in convention video laryngoscope and rigid video laryngoscope, unlike: it is of the invention
The insertion section 16 of handle in fine soft video laryngoscope be it is soft, can be with free bend.And insertion section 16 includes curved
Pars convoluta 17 can be bent at least 180 degree, lower at least 130 degree of bending above.The physiological structure for especially meeting bronchium, will not cause
Patient's discomfort or accidental injury.
The operation portion 15 is placed in usually on bracket 19, and display host is wirelessly sent to picture signal greatly
On display screen 121, realize that large-size screen monitors, smaller screen watch image simultaneously.
In these above-mentioned embodiments, all camera modules refer both to miniature camera module.In above-described embodiment
Fine soft video laryngoscope, the problems such as miniaturization, fever, difficult intubation, suction sputum, by using miniature, low-power consumption, high picture
The imaging sensor of element, use is miniature, high-power LED light source, and using can free bend insertion section 16 and service aisle 14,
In conjunction with technologies such as image procossing and control circuits, achieved the effect that very well it is fine, without heat, difficult intubation, suction sputum, meet soft
The requirements of video laryngoscope, therefore fine soft video laryngoscope of the invention is suitble to the difficult tracheae such as deep or more bronchium
Intubation, suction sputum, administration etc..The technology of above-mentioned fine soft video laryngoscope applies also for the other fine cavity diagnosis and treatment (ratios of human body
Such as portable electronic piece bronchoscope), medical ultra-fine endoscope, the fields such as fine industrial endoscope.
The fine soft video laryngoscope, utilization is more miniature, low-power consumption imaging sensor and miniature, high brightness LED,
This provides technology for the miniaturization of soft video laryngoscope and guarantees, the fine soft video laryngoscope in the present invention is domestic even state
Most thin laryngoscope on border, is also more suitable for the physiological structures such as patient throat, trachea-bronchial epithelial cell.Using fine soft view of the invention
Frequency laryngoscope can overcome the defect of existing video laryngoscope, provide conveniently for the use of operator, when also mitigating patient's inspection, treatment
Discomfort.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the invention.Therefore, the description and the appended drawings should be considered as illustrative
And not restrictive.
