Abstract
General surgical procedures are subject to low-light conditions or a narrow angle of view, and such limitations in light limit visibility and complicate the given surgical procedure. Conventional lighted surgical tools rely on an external light source, which may be oriented into a cavity or mounted on a surgical instrument such as retractor, endoscopes, or suction tubes. However, such conventional lighted instruments do not provide adequate lighting during various surgical procedures. Here, we present a soft, miniaturized magnetic-enabled wireless surgical lighting patty. Specifically, the proposed surgical lighting patty that can be temporarily implanted into a cavity or surgical corridor provides lighting to the surgical subject and manages fluids in a surgical field. The surgical lighting patty is a multilayer patty, two outer layers of the lighted surgical patty and the center lighted layer. A reed switch in the central layer can activate the power supply in response to a magnet to emit the light from the light source. The result allows a dramatically simplified wireless operation. Moreover, it can provide various wavelengths of light to a surgical field for purposes such as illuminating the surgeon’s field of vision, exciting dyes, and sterilizing surgical fields.
Highlights
The majority of modern surgical lighting illuminates from an external source, a dissecting microscope, into a cavity or is mounted on a surgical instrument, such as retractors, endoscopes, orthoscopic tools, and suction tubes [1,2,3,4,5,6]
Bipolar forceps or suction devices with light sources attached at the tip could provide light for only short periods of time, in particular, when they are applied to a surgical field [8]
Various neurological procedures require deep dissection; the only light source consists of a microscope light oriented outside the patient [10,11]
Summary
The majority of modern surgical lighting illuminates from an external source, a dissecting microscope, into a cavity or is mounted on a surgical instrument, such as retractors, endoscopes, orthoscopic tools, and suction tubes [1,2,3,4,5,6] Such conventional implements and instruments are unable to provide sufficient lighting during various surgical procedures. Low-light conditions during aneurysm surgery render deep surgical approaches far more dangerous [8,9] It leads to limited visualization and a substantially increased risk of injury. As another example, various neurological procedures require deep dissection; the only light source consists of a microscope light oriented outside the patient [10,11].
