Description
Technical field
The present invention relates to a kind of supporting laryngoscope adjustable type thyroid cartilage positioner to be mainly used in treating throat diseases of human body, belong to medical device technology mechanical field.
Background technology
Head and neck tumour, in the treatment of throat diseases, due to the specificity of human body throat physiological location, is a kind of more difficult project in the clinical treatment operation of scope Wicresoft of throat.Supporting laryngoscope in now clinical has straight shape tubular support laryngoscope and arced tube supporting laryngoscope, even recently the design function epiglottis of exposure patient that can not comparatively be satisfied with when running into the more fat patient of build than more comprehensive Multifunctional adjustable self-retaining laryngoscope and before the position such as to combine.Operative doctor often need spend a lot of time and efforts to complete operation, the patient of especially special obesity.Operative doctor, when supporting laryngoscope is adjusted to optimum state, often fully need could expose surgical field of view with the thyroid cartilage that Hand supplementary presses patient.In actual mechanical process, operative doctor another hands while pressing patient thyroid cartilage fully exposes surgical field of view on the other hand carries out accurate operation, change often because pressing thyroid cartilage dynamics makes surgical field of view occur rocking and is unfavorable for the precise manipulation of another hands, carrying out laryngendoscope vocal cords related surgical, this inaccurate because locating during the operation such as Laryngeal papilloma, tumor laser ablation, expose and not exclusively to patient postoperative rehabilitation and pronunciation, unnecessary damage is brought to the injury that throat causes.
Summary of the invention
For above problem, the invention provides a kind of supporting laryngoscope adjustable type thyroid cartilage positioner, thering is provided during a kind of operation to make operator get a clear view by supplemental support laryngoscope, perform the operation meticulous, curative effect is high, operation risk is few, little to corrective surgery injury, the supporting laryngoscope thyroid cartilage positioner tool that post-operative complication is few, for reaching this object, the invention provides a kind of supporting laryngoscope adjustable type thyroid cartilage positioner, comprise bracket adjustment device case, connecting rod, thyroid cartilage positioner, thyroid cartilage fixed support and thyroid cartilage jointing plate, a pair movable rack is had in described bracket adjustment device case, adjusting gear is had between described two movable racks, the rotating shaft at described adjusting gear two ends is through bracket adjustment device case, there is length adjustment nut the end of described adjusting gear one end rotating shaft, the limited bit slice in end of described adjusting gear other end rotating shaft, the end of a movable rack of described a pair movable rack has the C type draw-in groove of C type draw-in groove bracket adjustment device case to be stuck on the support bar of supporting laryngoscope, described C type draw-in groove there is adjusting nut, there is Connection Block the end of another movable rack of described a pair movable rack, there is connecting rod described thyroid cartilage positioner side, the end of described connecting rod is connected with the link of Connection Block by connecting screw rod, there is adjustment hold-down nut described connecting screw rod one end, described thyroid cartilage fixed support one end is stiff end, there is a circle teeth portion the shown support bracket fastened stiff end outside of thyroid cartilage, the support bracket fastened stiff end of described thyroid cartilage is fixed in thyroid cartilage positioner by rotating shaft, angular adjustment screw rod is had between described two thyroid cartilage fixed supports, described angular adjustment screw rod is meshed with the teeth portion of the support bracket fastened stiff end of thyroid cartilage, described thyroid cartilage jointing plate has a pair, described thyroid cartilage jointing plate is between two thyroid cartilage fixed supports, described thyroid cartilage jointing plate is connected with thyroid cartilage fixed support lower end by bar.
Improve further as the present invention, there is clamp nut the both sides of described bracket adjustment device case and adjusting gear central axis, because bracket adjustment device case is enclosed within outside movable rack, therefore in order to prevent from movable rack from skidding off arranging clamp nut in the both sides of bracket adjustment device case and adjusting gear central axis, movable rack is clamped.
Improve further as the present invention, the side, end of described connecting rod has occlusion teeth portion corresponding with the occlusion teeth portion of the link side of Connection Block, is not easy to loosen after fixing by tooth engaged wheel mode.
Improve further as the present invention, described thyroid cartilage jointing plate is connected with thyroid cartilage fixed support lower end by expansion link, there is shank described thyroid cartilage jointing plate side, the shank of described thyroid cartilage jointing plate is inserted in the pole of thyroid cartilage fixed support lower end, there is setscrew nut described pole side, because thyroid cartilage jointing plate need be fitted in outside thyroid cartilage, and the build of people is often different, therefore preferably expansion link mode is adopted, to adjust according to different building shape.
Improve further as the present invention, outside described thyroid cartilage jointing plate, have protective pad layer, due to thyroid cartilage jointing plate be lean against patient's skin of neck therefore can at arranged outside protective pad layer, to prevent scratch patient skin of neck face.
Improve further as the present invention, described protective pad thickness 1-1.5cm, owing to being subject to operation restriction, protective pad thickness of the present invention is generally 1-1.5cm.
Improve further as the present invention, be steelframe in described thyroid cartilage jointing plate, one deck flexiplast layer was wrapped in outside, and thyroid cartilage jointing plate of the present invention has outside steelframe in also can being designed to and has flexiplast layer.
Improve further as the present invention, the flexiplast thickness 1-1.5cm of described thyroid cartilage jointing plate outside, owing to being subject to operation restriction, protective pad thickness of the present invention is generally 1-1.5cm.
Improve further as the present invention, described localizer material is the martensitic chromium rustless steel 7C27MO2 containing molybdenum, because the present invention is mainly used in location of operation, to material corrosion resistance, and sterilization requires high, and have corresponding hardness requirement, therefore need to adopt the above-mentioned martensitic chromium rustless steel 7C27MO2 containing molybdenum as main material.
The present invention compared with prior art, have the following advantages and effect: structure is simple, reasonable in design, convenient operation, can realize locating thyroid object by this device additional on the support of traditional supporting laryngoscope, it can give patient one steady and audible surgical field of view, so that patient can precise manipulation.Its adjustable support, adjusting screw(rod) and both sides support bracket fastened diagonal adjusting screw(rod) can fit various form thyroid cartilage and thyroid cartilage can be realized downwards left, and to the right to regulate, thus can operate according to the actual needs of patient, make the laryngendoscope of patient perform the operation can obtain better, more stable exposure, effectively expand use face.This product adopts stainless steel material manufacture to form, can cleaning and sterilizing, also can High Temperature High Pressure routine disinfection, sterilizes very convenient.
