Description
Technical field
This utility model belongs to medical instruments field, relates to the laryngoscope surgery instrument, is specifically related to be used for the visual throat expansion mirror and the supporting apparatus thereof of arthroscopic diagnosis in the cavum laryngis.
Background technology
The operation of carrying out the vocal cords pathological changes under the laryngoscope is that clinical hals,Nasen und Ohrenheilkunde is very practical and be the most normal operation of carrying out, it can carry out in cavum laryngis, avoided cervical incision, along with the fast development of related surgical apparatus, this modus operandi has begun to be used for the excision of some early stage laryngeal neoplasm.Practice shows, various relevant modus operandis all have its limitation at present, has in the time of clinically because of exposing the not good complication etc. that causes operative failure and produce tooth, cervical vertebra.
Clinical laryngoscope modus operandi commonly used has following several at present: 1) laryngeal mirror: major advantage is easy.During operation, patient's seat under the laryngopharynx surface anesthesia, utilizes laryngeal mirror, and by reflective demonstration laryngeal structure, the patient utilizes various curved larynx operating forcepies to operate.But need the patient to cooperate when operating on the one hand, short at patient's cervical region, when throat is responsive, usually can not fully expose; The patient operates under the illuminator picture on the other hand, and operating habit is different down with direct-view, and difficult the grasp so be mainly used in patient examination and taking foreign body at present, can't be done delicate procedure.2) hard tube laryngendoscope: major advantage is to pass through graphical presentation system record check result, but the same laryngeal mirror of basic principle of operation is mainly used in outpatient service replenishing as laryngeal mirror at present.3) fiber laryngendoscope: major advantage is can be crooked, when can not fully exposing, laryngeal mirror and hard tube laryngendoscope use, expose laryngeal structure, but the strength of supporting laryngeal forceps and openings of sizes etc. can't satisfy the requirement that laryngeal pathological process is handled, so also be mainly used in inspection at present.4) direct laryngoscope: be the classical modus operandi of throat diseases intracavity operation, carry out under the general general anesthesia.Its advantage is to expose laryngeal structure under direct laryngoscope, and the patient can handle various vocal cords pathological changes under direct-view.But during this laryngoscope operation patient's tooth is had compressing, damage tooth happens occasionally; And owing to patient's cervical region layback patient fat and that neck is short, especially need be had the patient of cervical spondylosis, owing to can not brute force allow its layback, in case dislocation of cervical vertebra, fracture (the extremely high paraplegia that is caused), expose not good so that pathological changes can't be handled or handle not exclusively.In addition, because the collar extension diameter of existing direct laryngoscope is less, inconvenience during some operating theater instruments operation, the general anesthesia tracheal intubation is slided, and makes troubles to operation technique.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of visual laryngoscope operating theater instruments is provided, and is specifically related to a kind of visual throat expansion mirror and supporting apparatus thereof, is used for the intracavity operation of throat diseases.
Operating theater instruments described in the utility model is upper bent type, for complying with the tapered throat dilator of arc.
The visual laryngoscope operating theater instruments of this utility model comprises visual throat expansion mirror and supporting apparatus thereof.
Described visual throat expansion mirror: adopting medical metal material is the basic material of making, and improves on the dilator basis, oral cavity that routine is used, and makes the last leaf and the inferior lobe of visual laryngoscope.
The described leaf of going up extends connection blade 2 by last petiole 1.The long 14-18 of described blade centimetre, be and comply with the camber of oral cavity to laryngopharynx, be the 100-140 degree with last petiole and be connected, the connecting portion of blade and last petiole is wide to be 3-4 centimetre, phases down closely to throat, width is 1.6-2.2 centimetre.It is camber that nearly handle 8-11 centimetre section is seen in its side of described blade, radius 8-11 centimetre, arc length 8-11 centimetre, comply with the radian of human oral cavity to the root of the tongue to cavum laryngopharyngeum, thick 0.6-0.9 centimetre of described radian section includes leaded light and image and receives cable, the connecting portion anterior view is provided with the joint 3 that connects external equipment, its both sides are made poroid, can utilize existing equipment, insert fiber cold light source commonly used and fiberoptic laryngoscope etc.Establishing image apart from connecting portion 8-11 centimeters receives and photoconduction mouth 4.6-7 centimetre of the prolongation segment length of coupling part, basic journey linearity becomes the 165-185 angle with the center line of above-mentioned camber.The end of last petiole is established adjustable supports sheet 5, is used for fixing on bracing frame, and the handle body of last petiole is established the draw-in groove 6 of spring card, fixing after being used to expand.
Described inferior lobe is by petiole, inferior lobe bow and lower blade are formed down.The structure of following petiole 1 wherein, spring stator 2 and inferior lobe bow 3 is substantially with the mouth-gag of prior art.The one side both sides of following petiole are established flange 7 and are used to insert petiole, and another side is established spring leaf and had fixed opening width, and the inferior lobe bow is used to connect described handle and sheet.The thick 1.5-2 millimeter of lower blade sheet, its first section 4, be bent upwards from bow and stride across central incisor, the camber that is 1.5 centimetres of radiuses, arc length 1-1.5 centimetre are seen in the side; Second section 5 face as the compressing hard palate, after first section, camber bending downwards is the dome shape that radius is 1.8-2.2, and wide 2.5-3.2 centimetre, arc length 2.7-3.5 centimetre, long 2-2.5 centimetre, the about 2.2-2.7 of arc length; The 3rd section 6 from second section, long 6-8 centimetre, make the scrobicula shape at the pharynx rear surface, holding tracheal intubation, its width of lower blade from first section 2.5-3.2 centimetre gradually excessively to 2.2-2.5 centimetre of far-end.
This utility model is furnished with supporting apparatus, described supporting apparatus is the laryngeal mirror that the laryngeal mirror of prior art is changed into upper bent type, its direction of laryngeal mirror after the improvement is opposite with former indirect laryngoscopic surgery apparatus, and the camber of its radian and laryngoscope of the present utility model are complementary.
The visual laryngoscope operating theater instruments of this utility model, its visual throat expansion mirror, can overcome the defective of existing laryngoscope, design according to the anatomical features in human body throat nature chamber and the operating habit of operative doctor, under the prerequisite of farthest avoiding tooth, cervical spine injury, can fully expose throat, cooperate the operating theater instruments that adapts, under the scope video, finish the operation of various meticulous larynx section, compared with the prior art, have following outstanding advantage:
(1) expanding blade camber does not need patient's cervical region excessively to face upward, and avoids the cervical vertebra problem;
(2) damage tooth is avoided at hard palate in mouthful interior pressurized position;
(3) expansible closing up, it is convenient to place;
(4) collar extension is big, and operating theater instruments is easy to operate;
(5) but the tracheal intubation relative fixed reduce to slide;
(6) go up rotatable, the locking of petiole end support sheet, when inserting laryngoscope, can turn to the collision between minimizing and the bracing frame.
This utility model can adopt present widely used intranasal mirror video operation technique pattern, positive operation, study and grasp easily, can improve the safety, effectiveness, ease for operation of disease surgery treatment in the pharyngolaryngeal cavity etc., be laryngoscope notional breakthrough of performing the operation, its application will have a brand-new prospect.
