Pneumatic laryngeal tissue forceps for ophthalmology and otorhinolaryngology department

Abstract

The invention discloses pneumatic laryngeal tissue forceps for the ophthalmology and otorhinolaryngology department. The pneumatic laryngeal tissue forceps comprise a seat plate. Grab handles are movably mounted on the left side and the right side of the lower surface of the seat plate through rotating shafts. A supporting rod is fixedly connected and assembled to the center of the lower surface of the seat plate; one end of a first compression spring is fixedly connected and assembled to each of the left side wall and the right side wall of the supporting rod; and the other end of each firstcompression spring is connected with one grab handle. A partition plate is fixedly connected and assembled to the center of the interior of the seat plate; electric air cylinders are arranged on the left side and the right side of the partition plate; and screw rods are fixedly connected and assembled to the output ends of the electric air cylinders. According to the pneumatic laryngeal tissue forceps, the grab handles are held by hands to resist the elasticity of the first compression springs; the grab handles are pushed elastically to adjust the proper expansion degree; and thus the forcepsare driven to be aligned at the laryngeal to be processed. Power sources of the electric air cylinders are controlled and the output ends of the electric air cylinders are controlled to be pushed out,so that manual controlling of the tissue forceps is avoided by applying forces with cylinders; and thus the overall tissue forceps can be dismounted to be received or disinfected.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and the specific field is a pneumatic laryngeal tissue forceps used in ENT. Background technique [0002] Throat diseases account for more than 1 / 3 of ENT diseases, and a considerable number of throat diseases require surgical treatment. Because the supporting laryngoscope can directly expose the glottis, understand the abnormality of the laryngeal structure in detail, and clarify the location and scope of the lesion, it was once the first choice for vocal cord disease surgery and was widely used in clinical practice. However, in actual clinical work, patients with difficult airways such as "small jaw", "high larynx" and "thick neck" can always be encountered. Ordinary support laryngoscopes cannot expose them smoothly and affect the completion of the operation. In the past, when encountering these situations, doctors often resorted to "laryngoschisis" or "surgery under fiberoptic lar...

AI Technical Summary

Problems solved by technology

However, in actual clinical work, patients with difficult airways such as "small jaw", "high larynx" and "thick neck" can always be encountered. Ordinary support laryngoscopes cannot expose them smoothly and affect the completion of the operation.

In the past, when encountering these situations, doctors often used "laryngosplitting" or "fiber laryngoscope surgery" for remediation. The existing laryngeal tissue forceps require manual operation, which increases the labor intensity of the operation, and cannot be disassembled for storage and decentralized disinfection.
