Description
Medical Instrument
Field of the Invention
The invention relates generally to illuminable medical instruments for use in apparatus for the inspection of body cavities, and in particular is concerned with single use illuminable medical instruments such as sigmoidoscopes.
Background of the Invention
Sigmoidoscopes are used by medical professionals to inspect the colon or rectum of a patient.
These instruments commonly comprise a disposable speculum iti the form of a hollow, light transmissive, plastic tube whidi is coupled, tvpicaliy via a screw-thread cotinection, to a non-disposable fibre optic head. A permanent light source is then coupled to die fibre optic hcad to aliow iliuniination of the body cavity.
lire fibre optic light head rypicaliy comprises ati outer steel case, and an inner steel mhe. A bundle of fibre optic fibres are santlwichetl between tire two layers, antI thcn connected to a permanent light source. Light is transmitted from the light source, along die fibre optic fibres and into the circumferential end edge of die specuium. The non-disposable fibre optic light head typically has a hinged window through which instruments such as biopsy instruments may he inserted and removed. The fibre optic light head is ilst-) usually provided with a spigot tbr connection to an insufflation bulb. This enables the bowel of the patient to be insuffiatcd \Vitli air to allow easier inspection of the body cavity.
The disposable speculums arc purchased in a cleati condition, ready for use. A new speculum is then coupled to a fibre optic lanip head in ortler to examine tire patient. After usc tire speculum is disposed of. The fibre optic lamp head is not disposable, and must he sterilised between uses to prevent any cross-contamination occurring. This is a costly and time consuming process and can of course give rise to cross contaminatioti if sterthsation is tiot properly conducted. The sterilisation process can also cause damage to the fibre optic cables within tire lamp head. In addition, the time taken to complete sterilisation of such a lamp head is significant. Hospitals will therefore tvpicdly need to purchase several expensive lamp heads to use during the course of a day since there is not time to sterilise the equipnrent between patients.
GB 2108391 describes a light conducting plastics speculum for a metlical instrument such as a sigmoidoscopc. The speculum is designed to receive hght from a non-disposable light source head.
US 2002/0095068 describes a sigmoidoscope which has a disposable fluid tight window placed in between a fibre optic head and the disposable speculwn. The disposable window protects the fibre optic head from contamination. \Vhilst the disposable window would allow inspection of the cavity, if instruments are to he used then the window must be removed, and then steriisation of the light head is requircd. Tn addition, the fitting of thc window would be time consuming and US 2010/0094092 describes a medical instrument with an integral light source. An LED is located in the handle of the device and light is transmitted from the LED along a light pipe towards the end of the part of the instrument that is inserted into the body cavity. The light pipe is constructed from a polymer that transmits light.
Tt would be desirable to provide an improved single use medical instrument, removing tlie requirement for sterilisation between patients whilst also improving illumination.

Detailed Description of the Preferred Embodiments
Figures 1 and 2 illustrate an llluminahle medical instrument shown generally at 1. In this example the instrument is a sigmoidoscope.
The illuminable medical instrument I comprises a handle 2 attached at one end to a llght head 3 which includes a light emitting portion. The light head 3 is shown attached to a standard light conducting speculum 4, forming an apparatus for use in the inspection of body cavities. In this example the speculum 4 is releasably connected to the light head 3 via clip means 5 (shown in more detail in Figures 2 and 4). The speculum 4 is an elongate tube made from a hght transmissive plastics material.
The light head 3 includes a viewing window 6 located opposite the speculum 4. The viewing window 6 enables a medical professional to view the illuminated body cavity through the speculum 4. The viewing window 6 is attached to the light head 3 Via a lunge 8 and a clip 7. The window 6 may be opened by pressing on the clip 7. Opening the window 6 aliows the introduction of instruments into the cavity through the speculum 4. The light heat] 3 also includes a spigot 9 for attaclment of insufflation means such as the insufflauon bulb 10 s]1own in Figure 2. Insufflation of the body cavity is used to aliow easier inspection of the cavity by the meeical professional. An insuftiation bulb lOis connected to the spigot 9 on the light head $ via a tube 13. The connection of the tube 13 to the spigot 9 is preferably a push fit connection. Air from the insufilation bulb 10 may he pumped into the body cavity through the spigot 9 which is in fluid connection with the interior of the speculum 4.
Figure 4 illusates a cross-sectional view through the instrument of Figure 1, ab)ng the length of the speculum 4. Inside the light head 3, located proximal to the viewing window 6 is a substantially cylindrical speculum mounting collar 17, into which the mounting portion 15 of the speculum is inserted (the mounting portion -15 of the speculum can he seen more clearly hi Figure 3). The collar 17 has a through bore 14 which is shaped such that the mounting portion of the speculum 4 fits closely inside the bore 14 of the collar 15, provieling an air tight seal between the speculuni 4 and the light heat] 3. The air tight seal between the speculum 4 and the light head 3 helps ensure that there are no leaks when the body cavity is insufflated via the spigot 9. ilie viewing \vitldow 6 closes onto one end of the collar 17. The bore 14 through the collar 17 allows an unobscured view down the spcculu[n 4 from the viewing window 6. The mounting portion 15 of the speculum 4 engages with the collar 17 axially along the length of the speculurn 4, stabilising the speculum 4 in position. The speculum 4 is also preferably supported by clips 5.
Tn the illustrated example there are two clips 5 securing the speculum 4 in position. The nose portion 5a of each clip S engages with clip mounting portions 18 on the speculum 4. The speeulum 4 may be released from the light head 3 by sliuply pressing down on the finger engaging portions 5h of the clips 5, and then pulling the speculum 4 away from the collar 17.
The clips 5 may be spring-loaded. Similarly, a new specuhum 4 may he attached to the light head 3 by pressing down on the clips 5, heating the iiiounting p tion 15 of the speculum 4 inside the coliar 17 and releasing the clips 5. Prior art devices use a screw thread connection located just underneath the clip mounting portions 18 to connect the speculum to the light head. Lse of a screw thread connection is far more time consuming.
As shown in Figures 4, 5, and 6, light emitting diodes ILDs) 11 are located inside the light head 3 and are arranged such that when the specuhum 4 is mounted inside the collar 17, the TJ7Ds 11 are aligned with the bottom circumferential edge 16 of the speculum 4. Light from the TEDs 11 enters the walls of the speculum 4 and is internaliy reflected and therehy ansmittcd along the wails of the speculum 4. Power for the LEDs Ii is preferably provided by batteries located inside the handle. 2. Alternatively, the handle could be. connectable to the mains electricity. The LEDs may be switched on using a switch 12 situated on the handle 2.
Preferahly the illuminable medical instrument 1 comprising the light head 3 and handle 2 is provided as one complete unit which is connectable to a standard light transmissive speculum 4 and then disposed of after a single use.
Alternatively, an apparatus for use in the inspection of hody cavities is provided as a complete unit comprising the illuminable medical instrument I and a speenlum 4 which is disposed of after a single use. In this ease the speeulum 4 need not he detachably inotmteel to the light head 3.
The iusufflation bulb 10, and connecting tube 13 could also fonn part of a complete unit which is disposed of after a single use.
