Description

Transesophageal ultrasonic probe protective sleeve and matched probe thereof

Technical Field

The application relates to the field of probe protective sleeves, in particular to a transesophageal ultrasonic probe protective sleeve and a matched probe thereof.

Background

The ultrasonic probe is directly placed in the esophagus through an esophageal echocardiogram (TEE), and the obtained ultrasonic image is clearer due to the fact that the ultrasonic probe avoids the interference of tissues such as the chest wall, the lung and the like and reduces signal attenuation, so that the ultrasonic probe is an important clinical examination technology, is mainly used for evaluating serious cardiovascular diseases such as endocarditis, heart occupation and the like, and is the 'gold standard' for diagnosing left auricle thrombus at present. In addition, TEE is widely applied in the fields of heart disease interventional therapy and surgery, is not only used for diagnosis of preoperative diseases and screening of indications, but also has important values for intraoperative monitoring, guiding of operation modes, postoperative curative effect judgment, follow-up and the like.

It has been generally accepted in the past that the risk of complications arising from TEE examinations is relatively low, about 0.2-1.2%. In recent years, with the development of interventional techniques, the TEE complications in cardiovascular disease interventional therapy are gradually increased, for example, when the interventional techniques are adopted to repair complicated mitral valve perivalvular fistula, the TEE complication risk can reach 6.1%, wherein more than half of the serious complications comprise esophageal perforation, tearing, hematoma, upper gastrointestinal hemorrhage needing blood transfusion and the like. In the study of a group of patients with interventional therapy of heart diseases (non-coronary artery diseases) by performing esophageal endoscopy in the perioperative period, the patients are often suffered from pharyngeal, esophageal and gastric injuries after TEE examination, wherein part of the injuries are mild lesions (limited to mucous layers), but serious lesions (lesions extending to submucosa, such as hematoma and mucosal laceration) are not rare.

The mechanism of the damage of the alimentary canal mucosa caused by the TEE is the thermal damage caused by the heat generated by the probe on one hand, and the pressure-related damage caused by the over-high pressure of the contact surface of the alimentary canal mucosa caused by the long-time forward bending of the probe tip on the other hand. TEE protective sleeves sold on the market at present do not have the heat insulation effect of the top end of the existing probe, and do not influence the function of the ultrasonic imaging effect. In addition, the existing TEE protective sleeve is not tightly attached to the TEE probe, a seam exists on the surface, the operation difficulty of a clinician is increased, the ultrasonic imaging quality is also influenced, the patient experience is poor, and the risk of complications such as esophagus injury is greatly increased.

Therefore, a TEE probe protective sleeve which is tightly (tightly) attached to the TEE probe, smooth and capable of automatically measuring the contact pressure between the TEE probe and the upper gastrointestinal mucosa and reducing the temperature of the TTE probe (cooling) is urgently needed, the experience of a patient is improved, the occurrence of complications is reduced, and the comfort and the medical safety of the patient are improved.
