Description

Surgical image guided arc laryngoscope

The present invention relates to a laryngoscope, and more particularly to an arc laryngoscope for surgery and having an image guiding function.

For the treatment of vocal cord polyps, nodules, cysts or tumors, etc., laryngoscopy is generally used. The traditional common laryngoscopy surgery mainly consists of rigid laryngeal direct surgery, and less frequently used fiberoptic endoscopic surgery. Among them, rigid laryngeal direct surgery, often because some patients have poor angle of the chin's throat, can not observe the throat needs surgery, resulting in surgery failure, in addition, it is easy to cause the patient's teeth to break. The use of fiberoptic endoscopic surgery is rarely used to enter the throat through the nostrils, but the fiber nasopharyngeal endoscope needs another assistant to help during the operation, and it is not easy to accurately locate, regardless of local anesthesia or general anesthesia, the success rate of surgery Very low.

In the case of hard laryngoscopy, the patient must be subjected to general anesthesia, and the patient's head should be reclined. The operator should hold the hard-throat direct mirror, and extend the patient's throat along the back of the tongue and expose the surgical area. Most of these surgical laryngoscopes have hollow passages to provide sufficient space for the surgical instruments to reach the deep throat area for surgery; however, such laryngoscopes have no photography and magnification functions, and the surgeon needs to use an endoscope or a surgical microscope. And magnifying the observation, and then selecting the corresponding instruments according to different conditions and different diseases to remove the lesions; therefore, hard-throat direct-to-lens surgery mostly requires the use of endoscopy, surgical microscope equipment and other photography and magnification tools to assist the operation, and increase the cost of surgical instruments and Medical costs, and the structure of the amplifier materials is complicated, and the movement is inconvenient. In addition, the rigid laryngoscope is straight and not ergonomic. Often because of the poor angle of the chin's throat, it is difficult for the operator to observe the throat requiring surgery through the rigid laryngoscope. Failure, in addition, it is also easy to cause the patient's teeth to break.

There is an image bending laryngoscope for assisting the endotracheal tube. A tiny camera lens is added to the front end of the curved laryngoscope, and the image of the throat is directly displayed on the screen at the handle. This technique improves the past. Seeing the entrance to the glottis, the intubation is more difficult. The laryngoscope has a flaky shape and no tube space. It is only used to observe the patient's throat or to guide the endotracheal tube into the correct position. It is not used for laryngeal surgery; and it will display the screen on the laryngoscope handle. Although it can directly observe the patient's throat, it has the disadvantages of increasing the weight of the laryngoscope, complicated structure and inconvenient carrying.

In view of the fact that the existing image bending laryngoscope is only used for observing the patient's throat and assisting anesthesia intubation, it is not possible to directly use the image bending laryngoscope for surgery; and the existing rigid laryngoscope for surgery needs to enlarge the laryngeal lesion. At the same time, additional equipment such as endoscopes and surgical microscopes are needed to increase the expenditure on surgical equipment, the structure of the equipment is complicated, the movement is inconvenient, and the ergonomics does not meet the opportunity of surgery failure.

The main purpose of the present invention is to provide a surgical arc laryngoscope having an image guiding function, which allows the operator to perform an operation to enlarge the throat of the patient through the image guiding device.

Another main object of the present invention is to provide an image-guided curved laryngoscope with simple structure, ergonomics and high mobility to improve the convenience, safety and success rate of the operation.

In order to achieve the above object, the surgical image guiding curved laryngoscope of the present invention comprises: a grip; a laryngoscope tube comprising a first end, a second end, a first passage and a second passage The first end to the second end of the laryngoscope tube have a curved arc shape, and the end cross-sectional shape is slightly C-shaped. The first passage is formed by the first end to the second end of the inner wall surface of the laryngoscope tube. a side opening passage, the second passage is an independent passage disposed in the laryngoscope tube, is disposed adjacent to the inner side wall of the laryngoscope tube, and is separated from the first passage by a wall surface, the grip is connected to The laryngoscope tube is near the first end; and an image guiding device is disposed in the second channel of the laryngoscope tube, and includes a tube body and a camera and an electrical connection respectively connected to the two ends of the laryngoscope tube The tube system is a flexible long tube. The tube body is provided with a signal transmission line connecting the camera and the electrical connector. The camera comprises a lens and a plurality of light emitting diodes, and the electrical connector is a signal transmission. Connector.

The surgical image-guided curved laryngoscope as described above, wherein the laryngoscope tube has a slightly concave side at the end of the endoscope and forms a third passage outside the laryngoscope tube.

The surgical image-guided curved laryngoscope as described above, wherein the grip is recessed with a fourth passage communicating with the second passage of the laryngoscope tube, and the tube of the image guiding device is along the second passage of the laryngoscope tube Wear the outside of the grip along the fourth passage of the grip.

The advantages of the surgical image-guided curved laryngoscope as described above are as follows:

1. The new type adopts the design of the curved laryngoscope, which conforms to the physiological curve of the human body. It is easier for the laryngoscope to enter the throat of the patient, and it is not easy to damage the teeth.

2. The curved laryngoscope is provided with a first passage for accommodating surgical instruments and has a separate second passage for receiving image guiding means without affecting the surgical space.

3. The present invention is provided with an image guiding device, which has image guiding and illumination functions, and can enlarge the image of the throat of the patient. The image guiding device is simple and light in structure, and can be connected to a computer or a handheld mobile device by using an electrical connector to transmit images and supply power without being connected to a fixed display device for convenient movement.

4. The laryngoscope tube of the present invention further forms a third channel on the outer side wall, and the third channel can be used to limit the endotracheal tube for patient anesthesia, so that the endotracheal tube does not affect the operation space, and at the same time, the third The channel also reduces the need for compression of the endotracheal tube for anesthesia, making the anesthesia process safer.
