“…The use of shape memory alloy (SMA) microactuators enables active bending of the catheter's distal tip. Furthermore, the integration of an array of microtactile sensors permits the catheter to be threaded along a path of least resistance, thus avoiding possible damage to the Figure 1 Layout of a micromechatronic surgical system vessel walls (Negoro et al, 1994). In the area of keyhole surgery, surgical tools are introduced into incisions of less than 1 cm.…”

“…Catheters are long and slender surgical instruments used to treat vascular abnormalities. For example, to treat an aneurysm in cerebral vascular surgery (Negoro et al, 1994) a microcatheter is inserted into the thigh and threaded to the carotid artery in the brain. When the tip of the microcatheter reaches the site of the clot, a microcoil is delivered to occlude the aneurysm sac.…”

There is a fast growing acceptance of minimally invasive surgery (MIS), in which surgical procedures are performed with the least possible damage to healthy organs and tissues. The reduction of recovery time, postoperative pain, infection risks and costs are some of the many advantages of MIS. Micromechatronic technologies involve the miniaturization of mechatronics devices like precision mechanisms, sensors, actuators and embedded electronics. They have played and will play a very important role in the advancement of MIS. They allow the possibilities of enhancing the surgeon's abilities where current MIS techniques do not permit the full range of human dexterity and perception. This paper discusses the objectives, roles, and some present and future applications of micromechatronics in surgery.

“…Current endoscopes cannot reach the middle 70% of the gastrointestinal tract, but a locomoting device might provide the flexibility to do so [10]. Similarly, the forces required to insert catheters into long, tortuous, or branching vessels can cause damage, but, with appropriate sensors and active flexion, these could be made safer [11].…”

“…The progress of the catheter is seen on video X-ray images. Tiny sponges or coils are inserted to produce clotting to occlude the aneurysm [11], [31]. It is difficult and dangerous to steer the catheter through tortuous vessels and branches, however, and there is very limited capability to manipulate objects.…”

Abstract-Many surgical procedures are now performed using the techniques of minimally invasive surgery (MIS), in which unnecessary trauma is limited by reducing the size of incisions to less than about 1 cm or by using catheters or endoscopes threaded through vessels, the gastrointestinal tract, or other tubular structures. Micromechatronic technologies have great potential to allow access to regions now inaccessible, or to enhance the surgeon's abilities in applications where current minimally invasive techniques do not permit the full range of human dexterity and perception. Key needs and applications in MIS are identified, and relevant technologies, methods, and systems issues in mechatronics are discussed. The authors' millirobotic system for MIS of the abdomen is used as an example.

“…For instance, cardiovascular catheterization is a major tool in invasive diagnosis and percutaneous surgical treatment. Conventional catheters, however, have many problems which should be solved in order to improve safety and curability [1,2]. They cannot move actively and their operation is extremely dependent on human skill.…”

This paper presents an integrated communication and control system for a multi-link active catheter. Links in the active catheter are connected with joints made of three SMA (shape memory alloy) actuators. The communication and control function units are distributed over multiple links and three common lead wires are used between the links and the outside controller. The links are addressed and the SMA actuators are driven by the circuit in the links. A MOS transistor with large channel width is used as switch for the SMA actuator. The circuit is realized by a standard CMOS technology. It measures 1.8 mm wide by 3.0 mm long. Link addressing and actuator switching functions of the fabricated chip have been successfully demonstrated. The minimum access time for addressing and actuating per single link was .
