Transesophageal ultrasonic probe placement assist device

Abstract

The invention relates to a transesophageal ultrasonic probe placement assist device. The assist device comprises an arc-shaped bent pipe body with a pipe cavity, the arc-shaped bent pipe body comprises a bent pharynx placement part, one end of the bent pharynx placement part is a placement end with an oblique incision, the oblique incision inclines towards an extending direction of the arc-shapedbent pipe body from an outer diameter side to an inner diameter side of the arc-shaped bent pipe body, and the other end of the bent pharynx placement part is a tooth cushion part; a blocking wing part is arranged at an outer end of the tooth cushion part, the arc-shaped bent pipe body is provided with a side opening corresponding to a left-right direction in a radial direction, and expansion andcontraction of the pipe cavity are achieved through the side opening by the arc-shaped bent pipe body; the arc-shaped bent pipe body has an elastic reset force for forcing the side opening to be opened, a locking device for tensioning the side opening to drive the arc-shaped bent pipe body to be in a contracted state is arranged at a position of the side opening, and the locking device is providedwith a control end which is located outside the blocking wing part and used for controlling the side opening to be locked and unlocked. The transesophageal ultrasonic probe is guided to be placed, sothat the ultrasonic probe can be conveniently and reliably placed, the operation efficiency is improved, and the injury to a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, specifically an auxiliary instrument for guiding an ultrasonic probe when inserting an ultrasonic probe through the esophagus during operation. Background technique [0002] Intraoperative transesophageal ultrasound monitoring is a monitoring method developed in recent years for cardiac surgery and other critically ill patients, which is beneficial to the judgment of patients' cardiac function and evaluation of surgical efficacy. Such patients often require insertion of a transesophageal ultrasound probe after endotracheal intubation under general anesthesia. However, because the patient is under anesthesia and the endotracheal tube enters the trachea through the throat, the spatial structure of the throat changes and becomes crowded. It was extremely difficult to place an esophageal ultrasound probe that was easy to place while awake. When it is placed, it often requires multiple b...
