Dilator for nasal surgery

Abstract

The invention discloses a dilator for nasal surgery, and the dilator comprises a supporting rod, a circular plate, an extrusion shell and an observation cylinder; a telescopic rod is slidably installed at the top of the supporting rod, the circular plate is welded to the top of the telescopic rod, a consulting screen is detachably installed on the side surface of the circular plate through a data jack, and the extrusion shell is slidably installed on the back face of the circular plate; an observation barrel is installed in the extrusion shell, two sets of conversion bases distributed in a mirror image mode are installed in the observation barrel, a disc is detachably installed at the tail end of the extrusion shell, a cleaning taper pipe is installed on the back face of the disc, and a respiration assisting ball is detachably installed on the back face of the cleaning taper pipe; and the breathing assisting ball is designed to be semispherical. Through the arrangement of the consulting screen and the arrangement of three groups of display screens inside, images of pore cavities inside the nasal cavity of a patient and the inner walls of the two sides of the nasal cavity can be magnified, consulted and observed at the same time, and lesion parts of the nasal cavity of the patient can be searched conveniently.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a dilation device for nasal cavity surgery. Background technique [0002] With the increasingly serious air pollution, people's respiratory system is easily affected, and there are various respiratory diseases associated with it. Among them, the nasal cavity, as the inhalation structure of the respiratory tract, is more prone to various diseases. Breathing is hindered, so the number of patients with nasal cavity diseases in the otolaryngology department of the hospital is gradually increasing, and relevant surgical operations are required to ensure that the nasal cavity can breathe normally. When undergoing nasal cavity surgery, a nasal cavity dilation device is needed. The nasal cavity is propped up so that the doctor can perform the operation. [0003] The defective that existing nasal cavity expansion device exists is: [0004] 1. The comparative document CN10599...

Problems solved by technology

In the utility model, first of all, the diffusion type expansion structure is adopted, which facilitates the expansion operation of the patient's nasal cavity, improves the convenience of the nasal cavity expansion process, reduces the workload of the operator and the cost of treatment, and at the same time reduces the impact on the patient during the expansion process. Second, there is a lubricating structure inside, which can lubricate the head end of the cannula, which reduces the sense of obstruction during the sliding intubation process, which is convenient for the cannula to slide into the patient's nasal cavity, and at the same time It also reduces the phenomenon of scratching the nasal cavity during the sliding process", but it is difficult for the device to realize multi-angle camera shooting of the inner wall of the patient's nasal cavity during use, which makes it difficult for doctors to find the focus of the patient's nasal cavity;
