Description

Integrated parotid duct exploration and irrigation equipment

Technical Field

The utility model relates to the technical field of medical devices, in particular to an integrated parotid duct exploration and perfusion device.

Background technique

Parotid duct perfusion therapy is an important technology for diagnosing Sjögren's syndrome. The parotid ducts of different people have different shapes and opening sizes and positions, which are difficult to distinguish under normal circumstances. Especially in patients with Sjögren's syndrome, not only are the openings particularly hidden, but the gland openings often atrophy, blockage, fibrosis, etc., and can only be explored with empirical multi-point elbow probes, which not only increases the patient's pain, but also often leads to operation failure. At present, the operation method of parotid duct perfusion lacks unified standardized equipment, which is also the main reason why this operation cannot be carried out smoothly and widely.

However, before perfusing the parotid duct in the prior art, the patient must first be asked to sit on a seat, keep his head up, and expose his entire oral cavity. After adjusting the external light source, the medical staff must first use an elbow probe to detect the parotid duct opening and remember the approximate position of the opening, visually inspect the smoothness of the probe's entry and exit around the probe, select a suitable type of syringe needle, and then re-find the opening position according to the map to inject contrast agents and drugs into it. This traditional method is not only very cumbersome, but also greatly increases the difficulty of coordination, leading to operation failure and iatrogenic injury.

To this end, we proposed an integrated parotid duct exploration and perfusion device.
