Abstract

A surgical site illumination device, such as a retractor, includes an attachment means 1 for attaching a light source to the device, a light transmitting means 3 featuring fibre optic light guides which track down to feature 7 allowing emitted light 6 into the surgical site, a means for leverage and stabilisation 2 allowing better engagement of 5 and better functioning in parting of the surgical site.

Description

Description
This invention relates to a device for providing improved illumination to a surgical site whilst maximising the available space.
This device was designed having observed surgical sites and appreciating the limited viewing window through which surgeons must work with the need to maximise the use of available space and the need for, optimum lighting conditions of the surgical site. The advancement of surgery means that smaller and smaller incisions are made in operations and the available viewing space of a surgical site is becoming more limited. To overcome these problems, the present invention proposes a surgical site illumination device comprising an internally housed lighting system within a retractor; the lighting system being in the form of fibre optic wire, which when connected to a light source transmits light from the proximal end, through the body of the retractor and to the distal end of the retractor emitting the light into the surgical site. The device was designed with the sole intention of providing a clearer and brighter surgical site for the operating surgeon whilst not occupying valuable working and line of sight space.
The invention will be described below with reference firstly to the material used to manufacture the device and throughout to the accompanying diagram in which: Figure 1 shows the retractor and the working features of the invention.
Material.
The material of the retractor would be a hard plastic, which can withstand mechanical forces placed upon it. Plastic was the chosen material for the purposes of being able to manufacture a retractor which can: * Be easily manipulated to produce the desired finished product.
* Withstand mechanical stresses to allow the function of parting the edges of the surgical site.
* Be sterilised for re-use.
* Be manufactured with an entirely closed, transparent window which can allow light to pass through and illuminate the surgical site. A closed window would be produced with the edges continuous with the rest of the retractor to ensure the retractor could be properly sterilised using current techniques.
Description
In figure 1, the start of the device, 1 is a section which allows a light providing system to be connected. This could be of a simple screw design allowing the light source, be that via a length of fibre optic cord attached to a light system, to be easily attached prior to use and easily detached after use. The end of the 2.
fibre optic cord providing the light would have the same screw design to enable the retractor to be connected into it.
The main body of the retractor, 4 is a long tubular piece of plastic with the fibre optic cord running within, the length of the retractor from end to end is about 30cm although this is not a definite length as different sizes may be manufactured but for the purposes of the description 30cm was chosen.
A smaller piece of plastic, 2 near the beginning protrudes at 90 degrees and acts as a stabilisation shelf; this enables the user to achieve leverage allowing them to pull the device to separate the edges of the surgical site. The precise shape of the moulding of the retractor may vary slightly to improve grip.
The retractor has a large flat panel, 5 at the end which extends at 90 degrees to the body of the retractor in the opposite direction of the stabilisation shelf. This panel would descend into the surgical site and would act as the contact area for the retractor. The dimensions of the contact panel could be typically between 4- 7cm wide, 7-10 cm long and 2-4cm deep although these dimensions are not absolute and are preliminary measurements produced to aid with the description. The contact panel has a window, 7 of around 4cm in diameter which faces away from the body of the retractor into the surgical site area; this window is made of clear plastic to allow the passage of light through into the surgical site. The window would be manufactured so that its edges are continuous with the plastic of the contact panel 5; this would ensure that no connection joints existed and would aid in the sterilisation of the equipment after use.
Moulded completely within the retractor are fibre optic wires, 3. These fibre optic wires can be of the sheathed variety or the unsheathed variety. The fibre optic wires extend from the beginning of the retractor where the light source is connected, 1, along the body of the retractor, 4 and down to the lower contact panelS; here they end against the clear plastic window, 6 and 7 facing into the surgical site area. When the retractor is in operation and connected to the light source the fibre optic wires would pass light from the light source along the retractor and would cast a field of light into the surgical site providing a brighter and clearer working environment without taking up any extra, unnecessary, useful space.
The moulding of the retractor would be continuous; the whole body of the retractor could be moulded from one piece with the fibre optics housed inside, this would ensure better sterilisation of the equipment as no grooves or connection lines would be present. The colour of the retractor could range from clear to black; black providing a similar function to the sheath of the fibre optics and enabling better use of the unsheathed variety within the retractor. 3.
