Abstract
The invention relates to an adjustable type thyroid cartilage positioning device used in a laryngeal operation and used for treating the laryngeal diseases of the human body. The adjustable type thyroid cartilage positioning device comprises a support adjusting device shell, a connecting rod, a thyroid cartilage positioning device body, a thyroid cartilage fixing support and a thyroid cartilage attachment plate. According to the adjustable type thyroid cartilage positioning device, the thyroid cartilage positioning device body is added to a traditional prop-up laryngoscope, and therefore the prop-up laryngoscope can be assisted in slightly adjusting the thyroid cartilage downwards or leftwards or rightwards within a certain range so that the thyroid cartilage can be well exposed, the assisting hand, for pressing the larynx, of the surgeon is liberated, and meanwhile operation view field shaking caused when the surgeon exerts uneven force by hand is avoided. By means of the adjustable type thyroid cartilage positioning device for the prop-up laryngoscope, the view field of the surgeon is made clear, the operation is fine, the curative effect is good, operation risks are less, injuries caused by the operation to a patient are less, and post-operation complications are less.
Description
Technical field
The present invention relates to a kind of supporting laryngoscope adjustable type thyroid cartilage positioner and be mainly used in treating throat diseases of human body, belong to medical device technology mechanical field.
Background technology
Head and neck surgery, 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 arc tubulose supporting laryngoscope, even the exposure patient's that design function can not be more satisfied in the time running into the more fat patient of build than more comprehensive Multifunctional adjustable self-retaining laryngoscope recently epiglottis and before the position such as combine.Operative doctor often need spend a lot of time and efforts to complete operation, the patient of especially special obesity.Operative doctor, in the time that supporting laryngoscope is adjusted to optimum state, often need could fully expose surgical field of view with the auxiliary thyroid cartilage of pressing patient of hands.In actual mechanical process, operative doctor another hands in pressing patient's thyroid cartilage fully to expose surgical field of view on the other hand carries out accurate operation, the variation that Chang Yin presses thyroid cartilage dynamics makes surgical field of view occur rocking and is unfavorable for the accurate operation of another hands, carrying out laryngendoscope vocal cords related surgical, this inaccurate because locating when the operations such as Laryngeal papilloma, tumor laser ablation, expose the injury not exclusively throat being caused and brought unnecessary damage to patient postoperative rehabilitation and pronunciation.
Summary of the invention
For above problem, the invention provides a kind of supporting laryngoscope adjustable type thyroid cartilage positioner, person gets a clear view can supplemental support laryngoscope when a kind of operation is provided to make operation technique, 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, in described bracket adjustment device case, there is a pair of movable rack, between described two movable racks, there is adjusting gear, 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 of movable rack has the C type draw-in groove of bracket adjustment device described in C type draw-in groove to be stuck on the support bar of supporting laryngoscope, on described C type draw-in groove, there is adjusting nut, there is Connection Block the end of another movable rack of described a pair of movable rack, described thyroid cartilage positioner one side has connecting rod, the end of described connecting rod is connected with the link of Connection Block by connecting screw rod, there is adjusting hold-down nut described connecting screw rod one end, described thyroid cartilage fixed support one end is stiff end, shown in the support bracket fastened stiff end of thyroid cartilage outside have a circle tooth portion, the support bracket fastened stiff end of described thyroid cartilage is fixed in thyroid cartilage positioner by rotating shaft, between described two thyroid cartilage fixed supports, there is angular adjustment screw rod, described angular adjustment screw rod is meshed with the tooth portion of the support bracket fastened stiff end of thyroid cartilage, described thyroid cartilage jointing plate has a pair of, 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.
Further improve as the present invention, there is clamp nut the described bracket adjustment device case both sides vertical with adjusting gear centrage, because bracket adjustment device case is to be enclosed within outside movable rack, therefore in the bracket adjustment device case both sides vertical with adjusting gear centrage, clamp nut is set movable rack is clamped in order to prevent that movable rack from skidding off.
Further improve as the present invention, end one side of described connecting rod has tooth engaged portion corresponding with the tooth engaged portion of link one side of Connection Block, after fixing, is not easy to become flexible by tooth engaged wheel mode.
