Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a conveniently-adjusted nasal laryngoscope controlled by a foot.

Background

Endoscopes generally refer to medical instruments that enter a human body through various ducts to observe the internal conditions of the human body. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. For example, an endoscopist can observe ulcers or tumors in the stomach, and an optimal treatment plan is made according to the observations.

The fiberoptic nasopharyngoscope is a medical instrument for examining nasopharynx, laryngeal part of pharynx and larynx, performing biopsy, surgical treatment of vocal nodule or small vocal cord polyp, and taking foreign body in pharynx. The optical fiber device can magnify the focus to thousands of times through the imaging technology of the microscope when the detailed examination of the throat is carried out, doctors can carry out outpatient operation treatment on vocal cord polyps, vocal cord nodules and other vocal cord pathological changes by using the magnified pathological tissues such as vocal cord cysts and the like through the self-carried operating forceps, the operation time is short, and patients have no pain basically. There is also a clinical need for injecting drugs and sucking body fluid at a target position, and although the nasopharyngoscope in the prior art has the function of injecting drugs, the nasopharyngoscope still has the following defects: 1. when the medicine injector is used, the problems that the hand is easy to slide and the force is unstable, so that the medicine injection process is not easy to control and the like exist; 2. because the nasopharyngoscope is a soft endoscope, the place where the medicine is sprayed easily slides in the medicine spraying process.

In addition, the endoscope is generally directly placed in a patient body for examination, but the situation in the patient body is complex, and sometimes the endoscope is driven to displace, so that the use of the endoscope is easy to lose control, and the use effect is poor; when the nasopharyngoscope is clinically operated, a patient needs to take a sitting position or a supine position according to the position of a foreign body, the patient also has position changes with different amplitudes in the sitting position or the supine position, and the position of the medicine injector also needs to change according to the position change of the patient at the moment, so that the nasopharyngoscope is prevented from damaging a target position or an approach position in the operation process, and the pain of the patient is increased; for convenience of examination, the scaffold is generally used for effective fixation and support in clinic, but the existing scaffold also has the following defects: the support frame used clinically is inconvenient to freely adjust the height and the angle; different patients and different environments have specific requirements on the height and the angle of the support frame, and if the height and the angle are wrong during examination, the patient's condition cannot be accurately examined, so that the patient's condition is possibly delayed, and irreversible influence is caused; while also potentially damaging tissue at the target and transit locations of the endoscope.

With the development of limited, intelligent and minimally invasive modern surgical operations, the clinical application rate of minimally invasive techniques is expected to reach 75%. However, in general, an endoscope apparatus used in clinic needs both hands of a medical worker for control and operation, the hands of a doctor cannot be vacated in the operation process of the operation and can be completed only by assistance of a nursing staff, the operation time can be prolonged to a certain extent, and the operation risk is increased; but also requires a high degree of compliance between doctors and nurses.
