Description
Affiliated technical field:
A kind of laryngoscope, belongs to medical device technology.
Background technology:
Since calendar year 2001 John A.Pacey embeds pick-up lens first in Macintosh laryngoscope, visible laryngoscope has obtained very large development.In order to reduce Macintosh eyeglass to swallowing the stimulation of rear wall and needing the mobility that incidence is larger, angle mirror sheet (45-60 °) visible laryngoscope (as current comparatively popular GlideScope, Truview evo2 etc.) that is that meets physiological angle arises at the historic moment.But, being angle mirror sheet laryngoscope has the following disadvantages: although 1. glottis exposes better, but there is sometimes tracheal intubation difficulty, main cause is,, eyeglass large according to the endotracheal tube angle of lens angle moulding (by the hard tube core in it) generous in oral cavity the large and eyeglass of occupy-place without gear hyoplastron etc., in some situation, when making endotracheal tube at entrance and entering glottis, be difficult to satisfactory to both parties, cause the awkward situation of " visible (glottis) inserted not enter ".2. the visual field is limited: once laryngoscope puts in place, just can only see glottis and the periphery thereof in camera lens front, while carrying out intubate subsequently, cannot see endotracheal tube propelling situation at (camera lens rear) in mouth, therefore may cause soft tissue injury.3. under normal air flue, the required more common Macintosh laryngoscope of time of intubate will be grown, and efficiency is lower.
Summary of the invention:
This utility model provides a kind of laryngoscope, object be to overcome existing visible laryngoscope being not easy to intubate, cannot take into account that endotracheal tube (camera lens rear) in mouth advances and normal air flue under the deficiency of the aspects such as intubate efficiency is lower.
This utility model solves the technical scheme that its technical problem adopts: scope type lens angle is adjustable, and anesthetic laryngoscope is made up of mirror handle and eyeglass two parts, be L-type, mirror handle is cylindrical shape, battery is inside housed, Xe lamp bulb is equipped with in its lower end, connection folder by mirror handle between mirror handle and eyeglass and to be welded on Connection Block on eyeglass in mating connection, detachably, amount to, and there is the function of on and off switch, eyeglass is based on Macintosh eyeglass, there is gear hyoplastron and protect dental lamina (having gag function concurrently), its special feature is as follows: three, far-end 1/3 eyeglass (that is gear hyoplastron) is free, be connected with eyeglass (that is gear hyoplastron) formation rotating shaft thereafter, protecting dental lamina arises from rotating shaft and connects (that is in eyeglass, far away by 1/3) locate, be 45° angle, after develop into gradually normal Macintosh eyeglass, there is the narrow flat tube seat of sealing the below that is close to gear hyoplastron, arises from Connection Block, terminates in rotating shaft junction, inside has fiberoptic laryngoscope and two to regulate the steel wire of lens angle to pass through respectively by adverse movement, the mirror body of fiberoptic laryngoscope is embedded in Connection Block, its light source interface is corresponding with the Xe lamp bulb on mirror handle, when going out tube seat, fiberoptic laryngoscope is connected with tube seat is soft, going out fiberoptic laryngoscope objective end and eyeglass (that is gear hyoplastron) far-end 1/3 after tube seat welds together, can be with the synchronous translation-angle of eyeglass, fiberoptic laryngoscope eyepiece hood diameter 32mm, can be visual, also ccd image collection and the display system of accessible standard, Connection Block is provided with and regulates the spiral regulating device of lens angle (is an axle system, rotatable and drive steel wire motion), one end of steel wire is connected with the gear positive and negative two sides of hyoplastron far-end (closing on rotating shaft junction) respectively, striding across after rotating shaft connection, the other end of steel wire is connected respectively with spiral regulating device, according to lever principle, be connected to fulcrum with rotating shaft, extract spiral regulating device, bending eyeglass while clockwise rotating (that is gear hyoplastron), while rotating counterclockwise, stretch eyeglass (that is gear hyoplastron), insert locking of spiral regulating device.
Beneficial effect: this utility model organically combines fiberoptic laryngoscope and the adjustable Macintosh laryngoscope (correction) of lens angle, can adapt to the air flue of multiple different characteristics, has increased portability simultaneously.For normal air flue, common laryngoscope is simple and direct efficient; If difficult airway, common laryngoscope provides to fiberoptic laryngoscope and provides powerful support at aspects such as opening, Macro orientation, suction sputums, makes intubate efficiency higher; The patients such as, cervical spine injury little for mouth opening, ankylosing spondylitis can be by regulating suitable lens angle to expose to reach good glottis; Simultaneously, based on Macintosh eyeglass, volume is little, have gear hyoplastron, protect dental lamina (having gag function concurrently), and the minimum intubate curvature brought of angle adjustable eyeglass etc. has effectively been avoided the situation of " visible, to insert not enter "; In the nearly 2/3 section of propelling that can manage by direct-view endotracheal tube of eyeglass, transfer to endoscopes management to far-end 1/3, like this, in facilitating intubate, can whole process take into account endotracheal tube; Lens design compactness, aluminum alloy material, durable, to sterilize with other scope is the same, use cost is low.
