Background technology
The employed intubate laryngoscope of hospital is divided into common laryngoscope and fiberoptic laryngoscope at present, and common laryngoscope must could accurately insert endotracheal tube when energy per os straight line is seen throat; Fiberoptic laryngoscope can be looked at throat straight when non-rectilinear, but fixed fiberoptic laryngoscope camber still can not be looked at throat straight in some cases, and conduit inserts the increase of trachea difficulty when camber is excessive.And two kinds of laryngoscopes all require cervical region and lower jaw to have certain mobility, otherwise laryngoscope is difficult to arrive throat; Laryngoscope and trachea will be jointly through the oral cavities in the tracheal intubation process in addition, can't carry out intubate to the patient of microstomia or limitation of mouth opening.
The utility model content
The purpose of this utility model just is to provide a kind of guiding fiber type laryngoscope, to solve above-mentioned defective of the prior art.
For achieving the above object, the technical solution of the utility model is to adopt a kind of guiding fiber type laryngoscope, comprise handle portion, bending section and video system, one end of described handle portion is connected with an end of bending section, described video system comprises eyepiece, optical fibers and light source, described eyepiece is located at the other end of handle portion, described optical fibers is located at the inside of described handle portion and bending section, described light source is located at the side surface of handle portion, it is characterized in that, the inner hollow of described handle portion and described bending section and constitute guiding channel, constitute the guiding inlet of described guiding channel at the side surface opening of handle portion, the other end of described bending section constitutes the guiding outlet of guiding channel.
Wherein, described bending section handle portion bending relatively.
Wherein, described bending section is a coiled pipe, also is provided with control handle on the sidewall of described handle portion, and described coiled pipe is connected with described control handle by pull rope.
Wherein, described control handle is unidirectional control handle, also be provided with on the sidewall of described handle portion and loosen button, the gear that links to each other with control handle and the described pin that loosens button control mutually interlock to carry out unidirectional fixing.
Wherein, described light source is luminous after being connected with handle portion by bayonet socket.
Wherein, be provided with the guiding tube core in the described guiding channel.
Wherein, described guiding tube core is flexible real core pipe.
Wherein, described guiding tube core is a hollow pipe, and this hollow pipe head end is the standard syringe connector.
Advantage of the present utility model and beneficial effect are according to above-mentioned guiding fiber type Pharyngoscope of the present utility model, to have characteristics such as easy to use, that the stimulation of boil on the nape opposite the mouth bottleneck throat is little, applied widely.
Description of drawings
Fig. 1 is the structural representation of guiding fiber type laryngoscope of the present utility model.
Among the figure: 1, handle portion; 2, control handle; 3, guiding inlet; 4, bending section; 5, eyepiece; 6, light source; 7, loosen button; 8, guiding outlet.
The specific embodiment
Following examples are used to illustrate this utility model, but are not used for limiting scope of the present utility model.
Fig. 1 is the structural representation of the guiding fiber type laryngoscope of present embodiment, comprises as shown in Figure 1: comprise handle portion 1, bending section 4 and video system, an end of handle portion 1 is connected with an end of bending section 4, and the video system comprises eyepiece 5, optical fibers and light source 6.Eyepiece 5 is located at the other end of handle portion 1, and optical fibers is located at the inside of handle portion 1 and bending section 4, and light source 6 is located at the side surface of handle portion 1.The inner hollow of handle portion 1 and bending section 4 and constitute guiding channel constitutes the guiding inlet 3 of guiding channel at the side surface opening of handle portion 1, the other end of bending section 4 constitutes the guiding outlet 8 of guiding channel.
Wherein, bending section 4 handle portion 1 bending relatively.Be specially, bending section 4 is made of coiled pipe, and also is provided with control handle 2 on the sidewall of handle portion 1, and described coiled pipe is connected with described control handle 2 by pull rope.Preferably, described pull rope is a steel wire rope.
Wherein, control handle 2 is unidirectional control handle, and also be provided with on the sidewall of handle portion 1 and loosen button 7, the gear that links to each other with control handle 2 and the described pin that loosens button 7 controls mutually interlock to carry out unidirectional fixing, press and loosen knob 7 pins and lift the releasing interlock, pull rope is loosened, and bending section 4 is lax.
And, can in above-mentioned guiding channel, be provided with the guiding tube core, the guiding tube core is flexible real core pipe or hollow pipe, can guide and insert endotracheal tube.Under the situation of hollow pipe, its head end is the standard syringe connector, therefore can also attract and injectable drug.
Work process to the guiding fiberoptic laryngoscope of present embodiment describes below.
Earlier bite-block is placed between cog up and down during tracheal intubation, bite-block is selected the ring-type hard sleeve for use, avoids the tooth bending section 4 that bites.Light source 6 is connected the back by bayonet socket with handle portion 1 luminous, and hand-held laryngoscope handle 1 is inserted laryngoscope bending section 4 through the bite-block inner chamber; The camber that rotation camber control handle 2 is regulated bending section 4, when eyepiece 5 is observed the tip arrival throat of bending section 4, insert the guiding tube core from guiding inlet 3, insert trachea through guiding outlet 8, press afterwards and loosen knob 7, the pin that loosens button 7 controls is lifted, the interlock of the gear that releasing links to each other with camber control handle 2, gear and the pull rope that is attached thereto loosen, and bending section 4 is lax, fixing afterwards guiding tube core, withdraw from the guiding fiber type laryngoscope of present embodiment, at last endotracheal tube is enclosed within on the guiding tube core and along the guiding tube core and inserts in the trachea, fixedly endotracheal tube withdraws from the guiding tube core.
