AI Technical Summary
Technical Problem
Existing eustachian tube balloon catheters are prone to puncturing human tissue during insertion due to inaccurate pre-detection, increasing surgical risks.
Method used
Design a nasal guide device, including a fixator, a push tube, and an elastic element. The elastic element provides an initial pulling force, causing the distal end of the Eustachian tube balloon dilation catheter to rebound when it touches human tissue, thus avoiding direct puncture.
Benefits of technology
It effectively protects human tissues, reduces surgical risks, improves surgical safety and accuracy, and enables convenient one-handed operation.

Abstract
The embodiment of the application provides a nasal introducer and surgical instrument, relates to the technical field of implanting instrument, and solves the problem that the front end of the eustachian balloon is easy to scratch the human body tissue in the pushing process in the prior art. The nasal introducer comprises a fixing device, a pushing tube and an elastic piece, the fixing device comprises a sliding part and an inner sleeve, the inner sleeve is provided with a containing chamber, the pushing tube is in plug-in cooperation with the fixing device, a groove is formed in the wall of the pushing tube, the sliding part is used for sliding in the groove, the elastic piece is arranged in the groove, one end of the elastic piece is connected with the bottom wall of the groove, and the other end of the elastic piece is connected with the top end of the sliding part. When the front end of the eustachian balloon in the embodiment of the application touches the human body tissue, the front end of the eustachian balloon will rebound, and the human body tissue will not be directly scratched, so that when the pre-detection is inaccurate, the human body tissue is directly scratched, the eustachian tube tissue is protected, and the risk of the operation is effectively reduced.
