Abstract

The utility model relates to an improved heart stabilizer containing a presser foot, a backup arm and a support. The support consists of a support tee, a fixing seat, a control handle and a control mechnism used for the separation and reunion of the joint surface between the support tee and the fixing seat as well as the position and activity of the backup arm and the presser foot. The vertical end of the support tee is connected with the top end of the fixing seat by rotating. The presser foot contains a presser foot leaf connected with an adapting piece by a shaft sleeve, wherein, the presser foot leaf is made of metal tube enhancing micro-elastic plastic. The plastic forms a cavity arm and negative pressure cavities, with each presser foot leaf provided with a plurality of negative pressure cavities. The angle can be adjusted between the tee of the support and the fixing seat, and between the presser foot and the adapting piece, thereby improving the applicability greatly. In addition, with a plurality of negative pressure cavities provided in the presser foot leaf, the air leakage of the whole presser foot leaf due to incompletely partial seal can be avoided effectively. The fixing seat generates additional thrust and positioning pressure by an eccentric shaft and friction. Furthermore, the clamping and positioning of the sliding draw and the fixing draw is convenient and reliable.
