“…Fiber optic sensors are broadly classified according to three measurement principles: light intensity modulation (LIM), (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39) fiber Bragg grating (FBG), (40)(41)(42)(43)(44)(45) and Fabry-Perot interferometry (FPI). (46)(47)(48)(49)(50)(51)(52)(53) The advantages and disadvantages of each measurement principle are as follows. First, the advantages of LIM sensors are that the sensor has a cheap and simple structure and is less affected by temperature change.…”

In a myocardial biopsy, the physician inserts the myocardial biopsy forceps into the heart chamber with fluoroscopic guidance and operates the forceps to collect the myocardium. The tip of the forceps has a gripper and a two-degree-of-freedom passive joint. The myocardial wall is difficult to see through a fluoroscopic image, and sampling may be missed due to the weak contact force and the large angle between the forceps and the myocardium. To solve these problems, we propose a contact force and bending angle detection mechanism for the forceps using optical fibers. The proposed mechanism has three built-in optical fibers and is connected to light-intensity-modulation-type optical sensors. Before contact, the light of the fibers leaks outside through the forceps shaft gap. When the forceps tip comes into contact with the myocardial wall, the external force reduces the shaft gap and the leak light amount. The physician can detect the contact force and bending state at the tip from the ratio of the three measured values. We evaluated the proposed mechanism in in vitro and in vivo experiments. We confirmed that the contact force under 1.4 N and bending angle over 30 deg can be detected.

Tactile Sensors for Minimally Invasive Surgery: A Review of the State-of-the-Art, Applications, and Perspectives

2020

Minimally invasive surgery has been one of the most significant evolutions in medicine. In this approach, the surgeon inserts specially-designed instruments through a small incision on the patient's skin into the body cavities, abdomen, veins or, arteries and performs the surgery on organs. As a major limitation, surgeons lose their natural tactile perception due to indirect touch on the organs. Since the loss of tactile perception compromises the ability of surgeons in tissue distinction and maneuvers, researchers have proposed different tactile sensors. This review is to provide researchers with a literature map for the state-of-the-art of tactile sensors in minimally invasive surgery, e.g. in robotic, laparoscopic, palpation, biopsy, heart ablation, and valvuloplasty. In this regard, the pertinent literature from the year 2000 on sensing principles, design requirements, and specifications were reviewed in this study. The survey showed that size, range, resolution, variation, electrical passivity, and magnetic-resonance-compatibility were the most critical specification to study for tactile sensors. Based on the results, some of the requirements, e.g., magnetic-resonance-compatibility and electrical passivity are of less generality and more applicationdependent; however, size, resolution, and range specifications differ for various applications and are of utmost importance.
