Description
Technical Field
The invention relates to a rivet mounting system for a support plate of a surgical implantation system for repairing a laryngeal function after partial laryngeal resection in laryngeal cancer surgery.
Background
Since the 40 s of the last century, the incidence of laryngeal cancer has tended to increase significantly around the world, accounting for the second place of head and neck tumors. Surgery is still the primary means of treating laryngeal carcinoma at present, with laryngeal resection being the primary surgical technique and its use is increasing. However, when the tumor is radically removed by using the laryngeal partial resection, the laryngeal cartilage stent is inevitably defective, the laryngeal stenosis possibly occurs after the operation, the patient needs to make a tracheotomy and wear a tracheal cannula for life, the life quality is seriously influenced, and the laryngeal cartilage stent is a hindrance for the patient to return to society. Modern oncology surgery requires that the physiological functions of important organs be preserved or reconstructed as much as possible on the premise of radical tumor resection to improve the life quality of patients. In order to preserve or reconstruct the voice, respiratory and swallowing functions of the larynx, laryngeal scaffolds have been a difficult problem for laryngeal cancer surgical treatment.
The applicant proposes a technical scheme (patent application number: 201510708450.0) of a surgical implantation system for repairing the laryngeal function after partial laryngeal resection in a laryngeal cancer operation on 24 th month 2015, and in the laryngeal resection operation, when the thyroid cartilage is partially or even mostly resected to generate defects, such as 1/2 or even 3/4 of the thyroid cartilage is resected, the surgical implantation system for repairing the laryngeal function is performed by utilizing residual laryngeal cartilage stumps on two sides, and a staple gun for releasing the staple are fixed, so that the reconstruction of the voice, respiratory and swallowing functions of the larynx is realized. The present invention is a further improvement to the method of installation of the dowel therein.
