Dilator for cardiothoracic surgery and prompting method

Abstract

The invention belongs to the technical field of medical instruments, and discloses a dilator for cardiothoracic surgery and a prompting method. The dilator comprises expansion columns, expansion handles, an amplifier, a peeping plate, a peeping seam, an alarm and a camera, wherein the expansion columns are located on the two sides of the dilator, the expansion handles are located at the bottoms of the expansion columns and connected with the expansion columns, the amplifier is connected with the expansion columns, the peeping plate is arranged below the amplifier, the alarm is located above the peeping plate, and the camera is located below the peeping plate. Expansion is guaranteed through expansion and contraction of the expansion columns, the expansion accuracy is guaranteed through millimeter accuracy, the reliability and safety of the dilator are improved, the peeping seam is arranged to guarantee that a doctor can observe the situation in time, and the practicability of the dilator is improved; and by analyzing and arranging big data of a historical patient during expansion, the medical staff can make more accurate judgment during the operation, and the operation of the medical staff can be more appropriately facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a dilator for cardiothoracic surgery and a prompting method. Background technique [0002] Cardiothoracic surgery also includes diseases of cardiac surgery and general thoracic surgery. Cardiovascular surgery studies heart and great vessel trauma, pericardial disease, congenital heart disease, acquired heart valve disease, ischemic heart disease, heart tumors, great vessel disease, heart Pacing and implantable defibrillators, dynamic cardiomyoplasty, heart, lung and heart-lung transplantation, etc. Therefore, very high precision is required for cardiac surgical instruments. [0003] Most of the existing devices rely on the doctor's artificial experience to expand, which cannot be completely accurate to the millimeter to ensure the accuracy of the expansion, and the traditional dilator will hinder the observation line of sight of the medical staff and affect the judgm...

AI Technical Summary

Problems solved by technology

[0005] 1. Most of the existing devices require the human experience of doctors to operate, and there is no accurate model for reference

[0006] 2. When the existing device is used, it will hinder the observation line of sight of medical staff, affect the judgment of medical staff, and the safety cannot be guaranteed
