Description

Auxiliary platform for minimally invasive otoscope operation

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to an otoscope minimally invasive surgery auxiliary platform.

Background

In recent years, the development of the otoscope technology is an innovation and breakthrough of another technology in the field of otosurgery after microscopy. With the progress of the high-definition technology of the otoscope, the otoscope surgery is rapidly developed, and the international otoscope undergoes the process of recognizing, questioning and accepting the development of the otoscope surgery. Endoscopic surgery is a product of combination of ear microsurgery and modern endoscopic technology, and the basic concept of the ear endoscopic surgery is consistent with that of ear microsurgery, but in theory, in addition to the ventilation function of eustachian tubes, the ventilation function of the upper tympanic cavity, namely, the anterior drum isthmus, the posterior drum isthmus and the pair of tympanic membrane tensor folds, is more focused. The effect of upper drum ventilation is emphasized with the protection of the mastoid mucosa and normal structures of the middle ear, which is a surgical approach that better fits the physiological function of the middle ear. Technically, the slim otoscope can cross a relatively narrow auditory canal, the camera can directly reach the operation field, so that operators can clearly see all corners around the tympanic cavity, even 0-degree mirrors can provide wide-angle vision, and the combination of the 0-degree mirrors and 45-degree or 70-degree mirrors can further observe the hidden part of the middle ear cavity under the condition that normal structures of the middle ear are not removed or are removed little. Because the mastoid process route behind the canal ear is not needed, unnecessary mastoid bone is avoided being ground, the original anatomical structure of the middle ear is better protected, and meanwhile, the hidden lesion part which is difficult to be seen clearly by a microscope can be more clearly observed so as to achieve the purpose of thoroughly clearing the focus. Because the post-incision is avoided, the patient does not need to have a regular ear circumference haircut before operation and need not to bind the head after operation, and because the unnecessary wounds are greatly reduced, the postoperative pain and discomfort of the patient are very slight, the postoperative recovery of the patient is fast, and the hospitalization time is short.

The rapid development of the minimally invasive otoscope surgery also provides new challenges for otologists, the otoscope surgery itself has its own disadvantages, and unlike the operation under a microscope which can be operated with both hands, the otoscope surgery is operated with one hand, and has inconvenience in terms of handling bleeding from the operative field and some fine operations, currently there is a "two-person three-hand" technique, the doctor must rely on an assistant to hold the scope, and communication and coordination between the doctor and the assistant are also a problem, so that a plurality of interference factors are brought to actual operation, and in actual operation, the otoscope is easy to be stained with blood, and the wiping lens needs to be taken out repeatedly, seriously affecting the operation progress. The prior Chinese patent application number 201910081394.0 discloses an external auditory canal support for otoscope surgery, which realizes the cooperative operation of both hands of a single person under the otoscope, but still faces the difficult problem that the use is influenced by blood contamination of the otoscope.
