Pushing-open device for mouth neoplasm excision

Abstract

The invention discloses a pushing-open device for mouth neoplasm excision. The pushing-open device for mouth neoplasm excision comprises a pushing-open device right part and a pushing-open device leftpart which are symmetrically arranged, wherein the pushing-open device right part and the pushing-open device left part comprise a mouth pushing-open groove, a first stage pushing-open rod, a secondstage pushing-open rod, an pushing-open handle, a telescopic structure and a protection sleeve; each first stage pushing-open rod is connected to the lower end of the corresponding mouth pushing-opengroove; each second stage pushing-open rod is fixedly connected with the corresponding first stage pushing-open rod; each pushing-open handle is fixedly connected with the corresponding second stage pushing-open rod; each telescopic structure is located at the center position of the corresponding mouth pushing-open groove; each protection sleeve is in sleeving connection with the external surfaceof the corresponding mouth pushing-open groove; and the pushing-open device right part is in crisscross connection with the pushing-open device left part through a second stage connecting shaft. According to the pushing-open device for mouth neoplasm excision disclosed by the invention, a primary lesion is sufficiently exposed, so that a surgeon can completely and thoroughly cure neoplasm smoothly, and additional damage brought by manual excessive traction can be reduced.

Description

technical field [0001] The invention relates to the field of oral and maxillofacial head and neck tumor surgery, in particular to a spreader for oral tumor resection. Background technique [0002] At present, the radical surgery of oral and maxillofacial head and neck tumors, especially the radical surgery of tongue cancer, mouth floor cancer, and oropharyngeal cancer, requires the mandible to be temporarily severed. In order to fully expose the primary tumor, more than two assistants are often required to use the thyroid retractor to pull the primary tumor to both sides to reveal the primary tumor, and to open the mouth with a mouth gag. Due to the narrow surgical field of oral and maxillofacial surgery, too many assistants will affect the surgical field of the main surgeon, and the force cannot be controlled evenly when the thyroid retractor is artificially pulled to expose the surgical field. Injury, the force is too light and the surgical field cannot be fully exposed, ...

AI Technical Summary

Problems solved by technology

Due to the narrow field of view of the oral and maxillofacial surgery, too many assistants will affect the surgical field of view of the chief surgeon, and the force cannot be uniformly controlled when artificially pulling the thyroid retractor to expose the surgical field. Excessive force often causes local muscle tears, which brings additional pain to the patient. Injury, the force is too light and the operative field cannot be fully exposed, which affects the radical treatment of the tumor by the main surgeon

In addition, after mandibular incision, the mandible and maxilla are not in the same plane, and the commonly used gags cannot support the upper and lower jaws well.
