AI Technical Summary

Technical Problem

Existing ENT drug delivery devices are difficult to achieve multi-angle independent adjustment of the terminal drug delivery direction, active bending and locking of the catheter, and suppression of hand tremors, resulting in problems such as drug delivery blind spots, inaccurate operation, and poor safety.

Method used

It adopts a multi-degree-of-freedom independent adjustment structure composed of a spherical hinge and a movable toothed ball, combined with a snake bone structure and a closed-loop metering feedback system of electric injection pump and flow sensor, and with a vibration suppression module built into the handle, to achieve flexible adjustment of drug delivery direction, precise bending and locking of the catheter, and suppression of hand tremors.

Benefits of technology

It effectively covers laterally concealed lesions, ensures accurate drug dosage, reduces the risk of mucosal abrasion and tympanic membrane damage, and improves operational stability and safety.

Abstract

This invention discloses an ENT drug delivery device and system in the field of medical device technology. The device includes a drug delivery catheter assembly comprising a main tube segment, a daughter tube segment, and a terminal drug delivery device. The daughter tube segment has several joint units distributed along its axial direction, which are hinged to each other. Each joint unit contains an angle sensor. A grip handle is detachably connected to the drug delivery catheter assembly and contains an electric infusion pump and a flow sensor. The grip handle is detachably connected to a support plate. A central processing unit (CPU) is also located inside the grip handle and is connected to the flow sensor, angle sensor, and electric infusion pump. This invention utilizes a multi-degree-of-freedom independently adjustable structure formed by spherical hinges, combined with a serpentine structure, to allow the atomized drug delivery direction to be independently adjusted in pitch and rotation angles based on the bending posture of the daughter tube segment. This effectively covers laterally hidden lesions such as deep nasal passages, pharyngeal recesses, and the surface of the tympanic membrane, eliminating drug delivery blind spots.
