Oral cavity drag hook system and method of use thereof

Abstract

The invention discloses an oral cavity drag hook system and a using method thereof. The oral cavity drag hook system comprises an oral cavity drag hook device, a soft palate drag hook device and a pharyngeal back wall soft tissue opening device, wherein the oral cavity drag hook device comprises a tongue pressing component, a first adjusting part and an upper tooth opening component; the tongue pressing component and the upper tooth opening component are both connected with the first adjusting part, and the first adjusting part adjusts the tongue pressing component and the upper tooth openingcomponent to expand the lower jaw and the upper jaw; the pharyngeal back wall soft tissue opening device is positioned above the oral cavity drag hook device and comprises two soft tissue opening components and a second adjusting part connected with the two soft tissue opening components, wherein the second adjusting part adjusts the two soft tissue opening components to distract the pharyngeal back wall soft tissue; the soft palate drag hook device is positioned between the two soft tissue opening components, and the oral cavity drag hook system is easier to dilate the oral cavity, so that the back wall of the oral cavity pharynx is shown in front of an operator as much as possible, thereby maintaining a good and stable operation visual field, and meeting the requirements of the operator.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically, an oral retractor system for opening the oral cavity, pressing down the tongue, expanding the soft palate and the soft tissue of the posterior pharyngeal wall during an operation through the oral cavity and a method of use thereof. Background technique [0002] When performing anterior atlantoaxial surgery through the oral cavity, in order to facilitate the operation, it is necessary to open the mouth and press down the tongue to expose the skull base and the posterior pharyngeal wall in front of the upper cervical spine as much as possible. It is the codman retractor system. The codman retractor system mainly relies on the hand strength of the operator when opening the mouth and pulling the tongue. However, the size of the mouth of different patients and the strength of the muscles around the mouth are different, which makes it difficult for some patients to open the mouth. ...

[0002] When performing anterior atlantoaxial surgery through the oral cavity, in order to facilitate the operation, it is necessary to open the mouth, press down the tongue, and expose the skull base and the posterior pharyngeal wall in front of the upper cervical spine as much as possible. Currently, the commonly used It is the codman retractor system. The codman retractor system mainly relies on the hand strength of the operator when opening the mouth and pulling the tongue. However, the size of the mouth of different patients and the strength of the muscles around the mouth are different, which makes it difficult for some patients to open the mouth. The rear operation area is insufficiently exposed or too narrow to meet the operation requirements
