摘要
This invention is about the test apparatus (1) used to evaluate the effectiveness of prosthetic rings used for remodelling of valve annulus during mitral and tricuspid valve prosthetic ring annuloplasty surgeries. It consist of a test ring (1.1) having the same shape and dimensions as the prosthetic ring to be used, the thread gaps (1.2) around this ring, corresponding to the locations of the sewing threads passed through valve annulus, and characteristic thread channels (1.3) that anchor suture threads temporarly during valve competency tests without giving harm to suture threads or delicate tissue of valve annulus. The test apparatus (1) gives surgeon the chance of trying different sizes of prosthetic ring matterials comfortably and observing the competency of valve during the surgery before giving the final decision.
