Description

Imaging laryngoscope

The present invention relates to an image laryngoscope, and more particularly to an image laryngoscope provided with a plurality of lenses for increasing the field of view to improve the accuracy of performing surgical and surgical interventional treatments.

The main purpose of the imaging laryngoscope is to display images of the inside of the human throat. In a situation, when the patient's throat is blocked by foreign matter, the position of the foreign object needs to be clearly known in order to remove the foreign object.

Another condition is a tool for performing endotracheal intubation. For example, during a patient's general anesthesia, the patient's respiratory passage needs to be maintained. At this point, an artificial respiration path that allows air to enter the patient's lungs is created by an artificial catheter inserted into the patient's trachea. One of the difficulties in intubation is to ensure that the artificial catheter is inserted into the trachea leading to the patient's lungs, rather than being inserted into the esophagus leading to the patient's stomach. In order to avoid the problem of life safety caused by the mistake of tracheal intubation, the image laryngoscope is placed in the oropharynx to expose the glottis. When part or all of the glottis enters the field of view, the artificial catheter is inserted into the patient's trachea as a guide style for the subsequent tracheal intubation to ensure that the tracheal intubation performed thereafter proceeds smoothly.

The above-described image laryngoscope is still at risk whenever it is used to remove foreign bodies or for endotracheal intubation. The structure of human organs is precise and the field of view is still limited. In the course of the operation, if there is any error, the serious person may even threaten the life safety of the patient.

In the early stage, in order to complete the view of the operation site, there is a person who uses a mirror. However, this approach has a narrow field of view and is quite dependent on the experience of the operator, resulting in a high degree of risk. The existing video image laryngoscope enters the market, and the image capturing device is used to present the image of the operation site to an external display. However, due to its optical structure, its field of view is still insufficient, and it is impossible to perform surgery at the same time when viewing an image, which is inconvenient to use. Moreover, it still has the disadvantages of complicated structure, high price, and high consumption of consumables.

Therefore, the field of laryngeal surgical instruments still needs to develop an image laryngoscope with a large field of view, simple structure, low price and convenient use.

In particular, the present invention provides an image laryngoscope which can increase the field of view and form a stereoscopic image by using multiple lenses. The imaging laryngoscope has a hollow passageway for passage of a clamp, suction, guide strip or other therapeutic device. The second lens image is transmitted to the external display, the head mounted display device or through the eyepiece mounted on the connecting portion, so that the image is not obscured during the operation to obtain a wider field of view and reduce the surgical error.
