“…The incorporation of irrigating channels is said to assist as is the newly developed vibration mechanism that physically cleans the lens surface. 31 Of these technical changes to laparoscopes, only the Japanese group 31,32 has studied them in detail. Laparoscopes with self-cleaning mechanisms appear not to become commercialized due to cost and practicality where additional size and potential for problems with operation or sterilization are a disadvantage.…”

Laparoscopic surgical procedures are becoming common across surgical specialties, including urology. Maintaining a clear field of vision is paramount in such procedures not only for safety by preventing inadvertent injury, but also to improve precision and reduce operative time. Laparoscopic lens fogging (LLF) is a major impediment to a clear visual field during laparoscopy and is caused by condensation as well as particulate debris, blood, and smoke accumulation on the scope lens. Despite many available techniques to improve vision during laparoscopy, available data on etiology and methods to improve vision have only sporadically been considered in the literature. The objective of this review was to summarize current literature on the etiology of LLF and other causes of poor vision during laparoscopy and also review the current approaches for minimizing or reducing such events. In summary, although the etiology of LLF is well understood, that is, temperature and humidity differences, the methods to reduce its occurrence lack significant data. Of those methods that are often espoused, most are not supported in the literature, such as warmed and humidified insufflation gas, or simply lack data, such as antifogging solutions.

“…Therefore, from the viewpoint of invasiveness, this approach is not used. On the other hand, Ohdaira et al [8] have proposed the use of a wireless camera system for minimally invasive surgery, especially natural orifice translumenal endoscopic surgery (NOTES) [9]- [11]. The miniature camera is inserted into the patient's body via a trocar, and it transmits images of a wide operative field using a radio frequency signal.…”

A big advantage of minimally invasive surgery is the quick recovery afforded by the minimal physical injury sustained by patients. However, the operative field provided by the endoscope camera is rather narrow. This paper discusses a new broad-view camera system, which is capable of providing a wider view of the internal organs during minimally invasive surgery. This system consists of a camera unit for capturing the image and a monitor for displaying the captured image. With the use of this system, the invasiveness of the procedure does not increase, and the other specifications of current minimally invasive surgery are maintained. Furthermore, it can function as a second camera (in addition to the one attached to the endoscope) and can help assess the overall state of the target area. In this paper, we present this a newly developed camera system, which is intended for use along with the proposed system. The camera system is composed of a miniature color CMOS camera, an indwelling needle, and an extra-thin connector. The specific design of the camera unit and the method for positioning it are shown here. The performance of this camera system has been confirmed through basic and laparoscopic surgery on animals.
