Abstract

The invention discloses an expander for cardiothoracic surgery and a prompting method. The expander comprises a supporting frame, sliding blocks, a connecting block, a gear and a first expansion handle. Connecting plates are mounted on the outer wall of the lower end of the supporting frame; chutes are formed in the outer walls of the opposite sides of the two connecting plates. The sliding blockis installed in the chute. A supporting plate is mounted on the outer wall of one end, penetrating through the chute, of the sliding block; racks distributed in parallel at equal intervals are arranged at the upper end of the supporting plate. A bearing is embedded in the connecting plate; a rotating shaft is installed in the bearing; a gear is installed on the outer wall of the side, penetratingthrough the bearing, of the rotating shaft; the gear is engaged with the rack; a connecting block is installed on the outer wall of one side of the connecting plate; and a limiting rod is installed inthe connecting block. By arranging the gear, the limiting rod and a spring, the effect of adjusting the wound expansion distance is achieved, the wound expansion stability is guaranteed, the situation that the observation sight of medical staff is blocked and judgment of the medical staff is affected is avoided, and the equipment practicability is improved.

Description

technical field [0001] The invention relates to the technical field of dilators, in particular to a dilator for cardiothoracic 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] After a massive search, it was found that the dilator devices in the prior art are typically similar dilator devices disclosed in the publication numbers CN204814005U, WO / 2017 / 177548, CN205163133U, etc., which are applied to thoracic surgery with large wounds, and can stably It is clamped on the wound and provides l...
