Submucosal uvulopalatopharyngoplasty tool with suturing function

Abstract

The invention discloses a submucosal uvulopalatopharyngoplasty tool with a suturing function. The tool comprises a main tool rest, a tool propeller is further arranged on the top surface of the main tool rest, a plurality of thread releasing devices are arranged at one end of the tool propeller, a protruding tool is arranged at the end, close to the thread releasing devices, of the tool propeller,the vertical distance from the main tool rest to the thread releasing devices is larger than that from the main tool rest to the protruding tool, a propelling device is arranged at the end, away fromthe thread releasing devices, of the tool propeller, and a needle holding device is further arranged on the tool propeller. Tool excision and suture are creatively integrated and synchronously carried out, and an operation can be completed by manually knotting after a suture. The thread releasing devices can remove the suture of a needle penetrating through the submucous adipose tissue, later manual knotting is facilitated, and the tool is simple and ingenious in concept, and solves the problem that existing submucous adipose tissue excision is difficult in manual excision and manual suturingin the oral cavity.

Description

technical field [0001] The invention belongs to the field of medical instruments, and in particular relates to a submucosal uvulopalatopharyngoplasty cutter with a suturing function. Background technique [0002] Obstructive sleep apnea hypopnea syndrome (OSAHS) is a common sleep breathing disease, and the incidence rate of adult males (2%-4%) is higher than that of adult females (1%-3%). Uvulopalatopharyngoplasty is an important method in the treatment of obstructive sleep apnea hypopnea syndrome. Surgical resection of the tonsils, uvula, and part of the palatoglossal and velopharyngeal arches expands the oropharyngeal space, relieves obstructions, reduces the collapse of the soft tissue in the pharynx, and smooths the airflow, thereby improving the degree of hypoxia. [0003] According to research reports, in submucosal uvulopalatopharyngoplasty, it is necessary to emphasize the tension-free suture that preserves the mucosa as much as possible, in order to eliminate incis...

AI Technical Summary

Problems solved by technology

Secondly, due to the stenosis of the pharyngeal cavity, the visual field during the threading process is limited, which makes the threading process extremely troublesome, and the force is not easy to control during the threading process, and the suture operation force is too small to pass the suture thread, resulting in threading failure. If it is too large, it may damage the tissues around the operation cavity, so it is urgent to design a velopharyngoplasty incision and suture device to solve the above problems
