Nasal surgery dilation device

Abstract

The invention discloses a dilation device for nasal cavity surgery, which comprises a support rod, a circular plate, an extruded shell and an observation tube. A telescopic rod is slidably installed on the top of the support rod, and a circular plate is welded on the top of the telescopic rod. The circular plate The side surface of the disc is detachably installed with a viewing screen through the data jack, the back of the circular plate is slidably installed with an extruded shell, and an observation tube is installed inside the extruded shell, and two sets of mirror images are installed inside the observation tube Distributed conversion base, the tail end of the extrusion shell is detachably installed with a disk, the back of the disk is installed with a cleaning cone, the back of the cleaning cone is detachably installed with a breathing aid ball, and breathing The auxiliary ball is a hemispherical design. The present invention is provided with a viewing screen and arranged with three sets of internal display screens to simultaneously enlarge and view images of the cavity inside the patient's nasal cavity and the inner wall images on both sides of the nasal cavity, so as to facilitate the search for the focus of the patient's nasal cavity.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nasal cavity surgical expansion device. Background technique [0002] With the increasingly serious air pollution, people's respiratory system is easily affected, which is accompanied by various respiratory diseases. Among them, the nasal cavity, as the inhaled structure of the respiratory tract, is more prone to various diseases. Breathing brings obstacles, so the number of patients with nasal diseases in the ENT department in the hospital is gradually increasing, and relevant surgical operations are required to ensure that their nasal cavity can breathe normally. The nasal cavity is propped up so that the doctor can perform the surgery. [0003] The disadvantages of existing nasal dilation devices are: [0004] 1. The reference document CN105999522A discloses an easy-to-use nasal cavity dilator, which "comprises two expansion members that can be inserted into the na...

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;
