Description
Technical field
The utility model relates to medical instruments field, specifically a kind of hard bronchoscope.
Background technique
Hard bronchoscope (hard mirror) is one kind of modern medicine equipment.With the development of medicine, hard mirror is also constantly being sent out
It opens up perfect.However in the late three decades, as software fiberoptic bronchoscope (Bronchofiberscope) is in clinical popularization, the application of hard mirror
It has significantly reduced.Compared with hard mirror, Bronchofiberscope needs to occupy certain air flue space in operation, for normal adults
Ventilatory dysfunction will not generally be caused, but its ventilatory function may then be influenced for children or airway constriction person, or even threaten
Life security.Hard mirror is able to maintain airway patency, and has side opening to be connected with ventilator in operating side, therefore hard mirror is also known as " ventilation branch
Airway wall ".
The operating method of hard bronchoscope is divided into conventional method and direct laryngoscope guidance method.
Conventional method: hard mirror mirror body first uses paraffin oil lubrication, the proximal end of the right hand mirror of operator, left hand thumb and index finger point
It is not put between lower jaw and upper lower teeth, to take care of one's teeth and open upper lower jaw, the inclined-plane oriented manipulation person of mirror body end, mirror body
Vertically into oral cavity, the proximal end that the right hand after uvula pushes hard mirror is seen, mirror body distal end raises root of the tongue portion slowly, exposure meeting
Detest, visible glottis opening, mirror body is rotated by 90 ° and slowly pushes through glottis after provoking epiglottis with the inclined-plane of hard mirror；Into after tracheae,
So that inclined-plane is kept in situ by 90 ° of mirror body convolution, is referred to left hand and airway wall is advanced to deeper air flue in a manner of rotating and promote.
Into after air flue, Ventilators are usually first connected, to keep patient to there is enough oxygen to supply under general anesthesia state.Then into
One step observes left and right main bronchus, if need to enter right main bronchus, patient's head is turned left, hard mirror mirror body, which slowly rotates, to be pushed away
Into by knuckle, mirror distal end can be promoted to intermediate bronchus in most cases；Such as enter left main bronchus, then the head of patient is to the right
Turn, upper and lower lobes bronchus can be observed in most cases.Complete the removal of hard mirror after operation also under direct-view, in moving in rotation into
Row.Most of patients is stopping reviving in intravenous applications anesthetic 10 to 20 minutes.Hereafter observation vital sign a few hours are (according to trouble
Person's concrete condition), the effect to anesthetic completely disappears.It is at least needed 2 hours according to the case where our hospital with experience, observing time.
Direct laryngoscope guidance method: operator's left hand holds laryngoscope, when observing epiglottis, i.e., raises the root of the tongue with the pressing plate of laryngoscope
And slightly take up epiglottis；The right hand operates hard mirror, and the tip of mirror body is made to pass through epiglottis in epiglottis lower part.At this point, operator turns by hard
Mirror body is simultaneously inserted into glottis depths by sem observation, while removing laryngoscope.The same conventional method of later operation.
It is " CN 201899479U ", entitled " hard multi-pass application No. is " 201020537694.X ", Authorization Notice No.
The Chinese utility model patent of road electric bronchoscope system " provides a kind of hard multichannel electronic bronchoscope system, packet
Include hard electronic bronchoscope and camera shooting host, cold light source host and monitor connected to it, the hard electronic bronchus
Mirror include scope main body and support mirror sheath, the scope main body include hard scope end, cold light source connector, data output end,
An at least instrument channel and two mutually independent air supply channels and attraction channel, hard scope end are integrated with leaded light
Optical fiber, optical lens, instrument channel outlet, air supply channel outlet and attraction channel outlet；The support mirror sheath includes working end
Portion, connects bayonet socket and channel connector, the support mirror sheath are connected through bayonet and connect with scope main body, the instrument channel
Diameter is greater than air supply channel diameter and attraction channel diameter.The hard multichannel electronic bronchoscope system can by oxygen supply, suction sputum,
Diagnosing and treating carries out simultaneously, greatly shortens required operating time, mitigates the pain of patient, effectively improve operation accuracy rate and
Safety.
But when clinical use, since the two sides of glottis have vocal cords, and the crack between vocal cords and arytenoid bottom claims
The most narrow position of cavum laryngis for rima glottidis, thus in use by existing hard bronchoscope be sent into glottis when, by
It is consistent with ontology bore in its head end bore, and head end is mostly inclined-plane, it needs for mirror body to be first rotated by 90 ° when into glottis, enter
Mirror body is circled round 90 ° again after tracheae, process is complicated, needs doctor quite careful and skilled；Nonetheless, it is still easy to sound
The vocal cords of door two sides cause to damage.In addition, when being operated to narrow air flue, hard bronchoscope when passing through narrow section,
Since hard bronchoscope shank distal end is thicker, the damage to narrow positions tissue will cause, the complication such as cause bleeding.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, the vocal cords of glottis two sides when a kind of reduction art is provided
And the hard bronchoscope of Airway damage.
In order to achieve the above object, the utility model provides a kind of hard bronchoscope, and ontology is tubular structure, institute
The distal end end face for stating ontology takes the form of inclined plane, and it is logical that the proximal end of the ontology forms the fibre channel port for being connected to proximal port, instrument
The outer wall of road port and air supply channel port, the ontology is equipped with scale marker line, which is characterized in that a gas is socketed in the ontology
Expander in road, the inside pipe wall of the ontology and the pipe outer wall of expander in the air flue are mutually agreed with, expander in the ontology and the air flue
For detachable structure；
The distal end of expander is stretched out by the distal end end face distal end of the ontology in the air flue, the distal end of expander in the air flue
Mouthful in the interior receipts shape collapsed at axle center, the proximal end of expander is stretched out by the instrument channel of ontology in the air flue.
Preferably, the angle α that the axle center of expander is formed in the proximal end of expander and air flue in the air flue is 5-30 °.
Preferably, in the ontology lateral edge its be axially arranged with developing line.
Preferably, the bore of the remote port of expander is 4-10mm in the air flue, and the bore of the ontology is 1.2-
1.8cm；
The axial length of the ontology is 50-60cm, and the axial length of expander is 54-64cm in the air flue.
Preferably, the proximal end outer wall of the ontology forms internal thread structure；
The proximal end outer wall of expander forms external thread structure in the air flue.
Preferably, it is arranged an annular hand grip outside the proximal end of expander in the air flue, one is formed on the shape handle can
The groove on port to be fastened on the instrument channel of the ontology.
The utility model has the beneficial effects that the utility model, which newly designs, expander in air flue, it is socketed on hard bronchus
In mirror ontology, remote port is exposed to body part in the interior receipts shape to gathering at axle center；In clinical use, air flue
The interior receipts shape port of interior expander is first advanced into glottis, narrow air flue, glottis, narrow air flue is easily propagated through since bore is smaller, again
Since the pipe outer wall of expander in air flue and the inside pipe wall of ontology mutually agree with, expander is brought directly to hard bronchus after entering in air flue
The ontology of mirror mitigates the pain of patient, and operate to the damage of the vocal cords and narrow air flue of glottis two sides when greatly reducing art
Simplicity effectively improves operation accuracy rate and safety.
