Surgical bent visual self-retaining laryngoscope system and using method thereof

Abstract

The invention discloses a surgical bent visual self-retaining laryngoscope system and a using method thereof. The self-retaining laryngoscope system comprises a self-retaining laryngoscope with a pipe cavity, a camera and an illuminating head which are arranged at the front end of the pipe cavity, image display equipment, an illuminating power supply, a first cable which is connected with the camera and the image display equipment, and a second cable which is connected with the illuminating head and the illuminating power supply, wherein the pipe cavity is of an arc-shaped structure. Since the structure of the self-retaining laryngoscope disclosed by the invention adopts a bending angle close to the geometrical size of a human body throat, the self-retaining laryngoscope can be easily inserted into the throat without using very great external force, human body tissues are not damaged and the surgical bent visual self-retaining laryngoscope system is more compliant with the ergonomic characteristic.

Description

technical field [0001] The invention belongs to the field of clinical medical devices, in particular to a curved visual support laryngoscope system for surgery and a use method thereof. Background technique [0002] The supporting laryngoscope is a common surgical instrument for benign tumors of the throat, vocal cord leukoplakia, early vocal cord cancer and other diseases; currently, the widely used supporting laryngoscope is placed in the oral cavity, which is usually a flat metal official cavity. When this supporting laryngoscope system is used in surgery, patients are required to have enough opening space; especially for patients who have difficulty opening their mouths, protruding upper incisors, small mandibles, thick and short necks, and obese patients, it is difficult to place a laryngoscope. In order to better expose the operation area, it is necessary to apply a lot of force to obtain a relatively ideal operation field, which can easily lead to complications such a...

Problems solved by technology

When this supporting laryngoscope system is used in surgery, patients are required to have enough opening space; especially for patients who have difficulty opening their mouths, protruding upper incisors, small mandibles, thick and short necks, and obese patients, it is difficult to place a laryngoscope. In order to better expose the operation area, it is necessary to apply a lot of force to obtain a relatively ideal operation field, which can easily lead to complications such as tooth damage, loosening or falling off, soft palate and palatal arch mucosa tear, and this kind of The placement process of the supporting laryngoscope requires extremely high operating skills and strength control of the operator

[0003] In addition, due to the narrow space of the anatomical structure of the human throat, the surgical field is directly narrowed, and only the surgeon can see the surgical field

The operable space for lesions in the operation is also extremely limited, and the surgeon can only operate with one hand. Although there are instruments such as throat forceps in the prior art that can target lesions in specific areas, they cannot adapt to ergonomic features, and it is difficult to remove the lesions at one time. Resection requires multiple repetitions, which virtually prolong the operation time. Long-term traction and compression during the operation can easily lead to postoperative complications such as sore throat and tongue numbness.

The supporting laryngoscope system in the prior art is only equipped with a light source and / or an endoscope device, and does not have multi-screen display and network connection functions, which is not conducive to the needs of teaching units for surgical teaching and remote consultation
