Problems solved by technology

It solves the technical problem that the two head ends of the chest opener in the prior art are easy to injure the patient's ribs, but the above chest opener can only be adjusted from one side, but since the chest cavity is symmetrical, if it is only adjusted from one side On the one hand, the adjustment range is small; on the other hand, the symmetry of the thoracic opening cannot be guaranteed, which is inconvenient for medical staff to operate, and it is easy to cause damage to the patient

Abstract

The invention discloses an auxiliary device for cardiac surgery, which includes a mounting frame and a spreading assembly, and the spreading assembly includes two spreading plates and a drive unit for driving the two spreading plates to move synchronously and reversely. The expansion plates are respectively fixedly installed on two mounting blocks at the bottom of the mounting frame, and the mounting blocks are slidably connected with the mounting frame. The driving unit includes a gear, a rack, a threaded rod, a driving rod and a connecting rod. On the gear, the application is equipped with a stretching component, which drives the threaded rod to rotate and move downward at the same time, the threaded rod drives the rack to move downward, the rack drives the two gears to rotate synchronously, and the two gears drive the drive rod to swing and drive The rod drives the installation block and the expansion plate at the bottom end to move outward through the connecting rod, so as to expand the chest cavity of the surgical patient, which is convenient for the medical staff to perform the operation. By adjusting the position of the cylindrical pin, the effect of adjusting the swing range of the driving rod can be achieved, thereby adjusting The movement stroke of the expansion board has strong adaptability.

Description

technical field [0001] The invention relates to the technical field of surgical auxiliary equipment, in particular to an auxiliary device for cardiac surgery. 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 tumor, great vessel disease, intervention Sexual therapy techniques, surgical treatment of cardiac arrhythmias, cardiac pacing and implantable defibrillator, dynamic cardiomyoplasty, heart, lung and heart-lung transplantation, etc. [0003] Cardiac surgery requires the patient's chest to be opened for surgery. In the past, the patient needed physiological breathing and the chest was in a state of continuous contraction, which affected the medical staff's surgical operations. Therefore, a device was required. A Chinese utility mode...
