Problems solved by technology

However, this patent is a hand-held manual operation device. In actual operation, it is easy to affect the accuracy due to the shaking of the operator's hand, which may cause damage to the patient. Secondly, the reliability of taking out the expansion plug after it is placed is not strong. , if the expansion plug is not placed, and the expansion forceps are simply used, during the operation, the fixation of the expansion forceps becomes an urgent problem to be solved

Abstract

The invention discloses a multifunctional punctum dilatation instrument, and relates to the technical field of medical instruments. The multifunctional punctum dilatation instrument comprises an operation assembly, an afterbrain fixing assembly, a forehead fixing assembly, a lower jaw fixing assembly, a dilatation assembly and the like. According to the multifunctional punctum dilatation instrument, the operation assembly has four degrees of freedom, and can flexibly realize the pose regulation and control of the dilatation assembly so as to adapt to the application requirements of specific stations; the dilatation assembly is provided with three dilatation heads, can dilate punctum, and can hover at a working position together with the operation assembly, so that a single doctor can perform surgical operation conveniently; the afterbrain fixing assembly, the forehead fixing assembly and the lower jaw fixing assembly can fix the head of a patient and adjust the posture of the patient, and can flexibly adapt to specific conditions of different patients.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, and particularly relates to a multifunctional apparatus punctum expansion. Background technique [0002] "Wind tears" is a common clinical disease, not only bring patients distress, severe cases can develop into chronic irritant conjunctivitis, eyelid and cheek diseases such as eczema and dermatitis, the main culprit, the tears of the abnormal the actual therapy, angioplasty punctum to be used, which is effective, simple, fewer complications, treatment can be repeated, is one effective method punctum abnormality treatment. Punctal plasty main application scenarios: punctal occlusion or occlusion, punctum stenosis (after dilatation treatment ineffective), the first end of the blocking lacrimal canaliculus, lesions involving headend punctum or canaliculus (such as nevi, not resulted in obstruction, but require surgical resection). [0003] The main method is punctum angioplasty bite cutting met...
