    摘要: In an apparatus for performing the coronary transluminal angioplasty, a tubular body (2) is housed in a shell (1) and has a disposable syringe (7) removably fixed thereto. A balloon catheter (8a) is connected to the syringe (7). A slide (20) runs axially inside the tubular body (2) and has a sleeve (17) fastened to it for pushing onto the plunger (18) of the syringe (7) so as to force inflation liquid into the catheter (8a). A threaded rod (11), that runs through the sleeve (17) and engages with a threaded section (20a) of the slide (20), is rotated by an electric motor (9) through a drive link (10) and pushes, with the opposite end onto a saddle (24) that in turn pushes onto a load sensing cell (31), while a counter device detects the number of rouds of the threaded rod (11) for metering the liquid forced into the catheter.
