Adjustable type thyroid cartilage positioning device used for prop-up laryngoscope

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 [0001] The invention relates to an adjustable thyroid cartilage positioning device for supporting a laryngoscope, which is mainly used for treating human laryngeal diseases, and belongs to the field of medical equipment technology and machinery. Background technique [0002] In the treatment of laryngeal diseases in head and neck surgery, due to the specificity of the physiological location of the human larynx, it is a relatively difficult item in the clinical treatment of laryngeal endoscopic minimally invasive surgery. Currently, there are straight tubular support laryngoscopes and arc tubular support laryngoscopes in clinical practice. Even the recently designed multifunctional adjustable support laryngoscopes with relatively comprehensive functions are not satisfactory when encountering fat patients. Expose the patient's epiglottis and anterior commissure. Surgeons often need to spend a lot of time and energy to complete the operation, especially for p...

Problems solved by technology

During the actual operation, the surgeon presses the patient’s thyroid cartilage with one hand to fully expose the surgical field of view while performing fine manipulation with the other hand. Often, the surgical field of view shakes due to changes in the pressure of the thyroid cartilage, which is not conducive to the precise operation of the other hand. Endoscopic vocal cord-related surgery, laryngeal papilloma, tumor laser resection, etc. The damage to the larynx due to inaccurate positioning and incomplete exposure has brought unnecessary damage to the patient's postoperative rehabilitation and pronunciation
