Definitions

  • This invention relates to the field of medical tools, in particular to specula.
  • a speculum is a commonly-used medical tool for opening or distending an orifice or cavity of a patient to permit examination of the interior and/or to enable a sample to be taken.
  • specula Various forms of specula are known, their designs varying in accordance with the body cavity to be inspected (e.g. vagina, rectum, ear, nostril). However, all forms of specula incorporate the same basic concept: elongate separator elements ('paddles', or 'blades'), typically having a curved cross section, are positioned edge to edge so that in combination they form an elongate channel. The channel narrows towards the end to be inserted into the orifice (the distal end) to aid the insertion process whilst remaining relatively wider at the opposing (proximal) end to facilitate visual examination or insertion of an instrument via the mouth of the speculum.
  • elongate separator elements 'paddles', or 'blades'
  • the channel narrows towards the end to be inserted into the orifice (the distal end) to aid the insertion process whilst remaining relatively wider at the opposing (proximal) end to facilitate visual examination or insertion of an instrument
  • the two blades are hinged at their broader ends, thus resembling a duck's beak.
  • the speculum is able to move to move between a closed configuration (i.e. blade edges are adjacent to each other) and an open configuration (i.e. blades are angled away from each other).
  • Handles are attached, usually integrally, at the hinged ends of the blades.
  • a light source is sometimes required or desired so as to aid visual examination of the cavity or cervix.
  • an extraction device may be used to remove or dissipate the smoke generated during certain medical procedures, such as biopsies or induction loop colopscopy, and which would otherwise obscure the practitioner's vision.
  • such tools, aids or other accessories are held in proximity to the speculum, either by the practitioner or an assistant. This means that either the practitioner has one less hand free due to holding the accessory, or another person needs to stand close by, potentially crowding the vicinity.
  • the accessory may be placed on a table, bed or a stand nearby. However, this results in the aid being relatively remote from the examination/procedure site, and renders the accessory less effective.
  • Chen discloses an arrangement wherein the accessory is either 'built into' the internal surface of a blade, or mounted to an external surface via a buckling belt, adhesive or other connection means.
  • the connection means employed by Chen result in either permanent attachment of the accessory or potentially bulky and cumbersome attachment means.
  • at least some of the connection means suggested by Chen may serve as traps for dirt or debris, thus posing a hygiene risk.
  • a light source is mounted within a housing having an integral clip member, the clip member being arranged such that a slot is formed between the housing and the clip member for receiving the speculum.
  • a longitudinally extending ridge is provided on the outside of the housing and is proportioned so as to engage with a slot provided on the interior surface of the speculum.
  • the ridge is received in the slot so as to effect longitudinal alignment of the housing within the speculum and provide resistance against relative lateral rotation. Therefore, any adjustment of the housing to direct light from the light source to a particular area is discouraged.
  • the clip member sits on the exterior wall of the speculum blade, resulting in a relatively raised profile and a distal clip end which may cause discomfort or tissue damage if it comes into contact with the patient's body.
  • a speculum comprising two or more blades moveable between an open and a closed position, and a light mounting device for mounting a light source on the speculum, the light mounting device comprising:
  • a first attachment means for attaching the mounting device to the speculum at or towards the speculum mouth

  • the first attachment means may be a hook or clip configured to fit around and/or grip the mouth of the speculum.
  • the first attachment means may be substantially C or U shaped.
  • the first attachment means permits sliding of one end of the mounting device in relation to the speculum.

  • the projection may be configured to snap-fit into the aperture provided on the speculum blade.
  • the light mounting device may be made to rotate about the projection when the hook is pushed, causing it to slide along the rim of the speculum mouth.
