AI Technical Summary

Technical Problem

Traditional transesophageal echocardiography (TEE) probes are uncomfortable to operate, have a high barrier to entry, are inefficient, and lack intelligent control, resulting in patient discomfort and long examination times.

Method used

An esophageal probe with an automatically rotating head was designed. It adopts an independent rotating structure and control module. By independently rotating the probe head relative to the insertion tube, combined with sensors and control module, automatic angle calculation and precise control are achieved. It includes an axial rotation structure and a slider rotation structure, and is equipped with a motor and flexible transmission components to reduce the risk of friction and jamming of the insertion tube.

Benefits of technology

It enables automatic rotation of the probe head, reducing patient discomfort, decreasing reliance on physician experience, improving examination efficiency and the success rate of obtaining standard sections, simplifying equipment structure, and reducing maintenance difficulty.

Abstract

The invention discloses a transesophageal probe capable of automatically rotating a head. The transesophageal probe comprises a probe head, a snake bone tube, an insertion tube, a rotating structure, a driving module, a sensor and a control module, the rotating structure comprises an axial rotating structure (a gear module) and a sliding block rotating structure; a flexible transmission part (a flexible shaft or a steel wire) is driven by a motor to drive the probe head to independently rotate by + / -15 degrees or + / -30 degrees relative to the insertion tube; the control module calculates the optimal rotation angle based on the heart anatomical structure and real-time image analysis, closed-loop control is formed in combination with sensor feedback, and a rotation stabilizing structure (a flange or an elastic piece) prevents clamping stagnation. The problems of discomfort of a patient, dependence on experience of a doctor, low efficiency and the like caused by rotation of a traditional probe insertion tube are solved, operation standardization is achieved, the comfort level of the patient and the examination efficiency are improved, the structure is simplified, the cost is reduced, and the device is suitable for transesophageal echocardiography examination.
