In many surgical procedures, doctors lack proper lighting, which increases the difficulty of operations, thus augmenting the chances for making a mistake like cutting into tissue or severing a blood vessel. With tens of millions of surgeries performed yearly in the US alone, the need to improve surgical visibility is crucial to enhance a surgeon’s precision.

Currently, surgeons depend on the support from overhead lights and head lamps, but these still do not provide adequate lighting as the surgeon can block the light path with their body and incision sites may be at awkward angles that limit light exposure from these devices.

Device Overview

Our device incorpotates a multipcolored light with a yankauer suction device in order to provide a surgeon with additional lighting during procedures. This is accomplished by linking an external light source to a yankauer through an optical fiber. In this way, there is a reuable light source paired with a disposable yankauer tip. Both parts have optical fibers attached to them which can in turn be connected by an adapter that we designed. A schematic of this setup is shown in Figure 2.

Figure 2: Schematic of device layout


To test our device we used a photometer to measure power readings for the light output of our device. Measurements were taken both directly from the light source and from the end of the optical fiber and are shwon in Figure 3. These measurements differ from wavelength to wavelength, but there is about a 90% loss in light intensity from the laser to the end of the optical fiber. This should not be an issue however, as the area of light produced at the end of the optical fiber provides a well lit region for a surgeon to visualize.

Market potential

The current market size for surgical illumination devices is 886.3 , million dollars. The market growth rate has been anticipated to grow by the rate of 3.89% per year in the next decade; ultimately reaching 993.8 million dollar market size in 2020.

One of the key factors resulting in the growth of the market potential for illuminating suction devices is the increase in aging population. This results in an increased demand for emergency care and growth in surgical procedures.

Another key factor is the paradigm shift from traditional health care service to a more advanced, high tech health care program which is directly coupled with growing need for medical devices. This shift has significantly boosted the market for medical suction devices.

There is an array of competitors in our market as the need to provide visibility conveniently during surgery continues to be an issue. Moving beyond headlamps and flashlights are competitors such as the Invuity PhotonSaber and the OneTrac product line. These devices also serve as single use illuminating suction devices. The major drawback is their bulkiness and price. While the PhotonSaber has a very nice handle, this type of design adds another layer of pricing. The OneTrac has an added benefit of being cordless and thus easier to use. The drawback is it’s extreme bulkiness and price. The pricing from the company put the OneTrac LX at $250. This type of pricing is 100 times more expensive than the range of our illuminating suction device which is expected to fall between $2.00 - $10.00.
