Definitions

  • This invention relates to a lens warming and cleaning device and particularly but not solely to the warming and cleaning of the distal portion of an optical instrument such as a laparoscope prior to insertion into a body cavity to prevent lens fogging.
  • Summary of the Prior Art A number of products are known in the art for warming and cleaning the distal portion of a laparoscope prior to insertion into a body cavity, thereby preventing the lens incorporated at the distal portion of the laparoscope from fogging when the laparoscope is first inserted into a patient thus obstructing the surgeon's view of the patient's internal organs. This fogging is caused as a result of moisture condensing on the laparoscope lens.
  • the lens temperature is below the dew point temperature of the insufflation gas that is pumped into the patient in order to increase the surgeon's work space within the body cavity.
  • the gas temperature is approximately 37°C as the human body will humidify the gas to approximately 100% relative humidity and raise the gas temperature to body temperature causing micro-droplets of water to condense on the colder laparoscope lens.
  • WOO 1/60239 of the University of Massachussets discloses a lens warming and cleaning device to warm and clean the lens at the distal portion of an optical instrument such as a laparoscope.
  • the lens warming and cleaning device includes a heat conducting tube sized and shaped to receive the lens portion of the laparoscope, a heating element thermally coupled to the exterior of the heat conducting tube and a cleaning member disposed within the conducting tube.
  • the preferred heating element is a heating pad that includes a flexible, air-permeable outer bag that encases a chemical mixture. The chemical mixture when activated generates an exothermic reaction thereby generating sufficient heat to warm the laparoscopic lens to between 45° and 60°C.
  • the cleaning member disclosed is a sponge inserted into the distal end of the heat conducting tube which is moistened with a saline solution plus an additive such as an anti-fogging additive or surfactant.
  • the warming and cleaning device is self-contained and does not require power to operate.
  • the exothermic heating pad can provide sufficient heat for up to six hours or more and needs to be replaced after one operating procedure whilst the remainder of the equipment is sterilized for re-use.
  • US patent 6,234,635 issued to Michael R. Seitzlinger and David Platts discloses an apparatus for maintaining a region of the proximal lens of a laparoscope at a temperature greater than ambient to prevent lens fogging during use.
  • the heating device is a pre- sterilized chemical heat pack which when activated, is attached in the region of the proximal lens end of the laparoscope for the duration of the operating procedure thereby ensuring the lens temperature is maintained to above ambient.
  • the heating device is disposable.
  • a defogging apparatus for heating and maintaining the lens and end portion of a laparoscope to above ambient temperature.
  • the apparatus includes an internal water filled receptacle for receiving the lens and laparoscope end portion surrounded by a second water filled container mounted onto a heating plate.
  • the heating plate includes a temperature control mechanism which ensures the water in the inner receptacle and outer container is maintained at a constant temperature.
  • the present invention consists in a warming device capable of warming the distal portion of an optical instrument including a lens portion comprising: a double walled cylindrical tube having an internal wall, external wall, upper surface and open distal portion with central cavity there between, a protrusion extending from said upper surface, sized and shaped to receive the lens portion of said optical instrument, a circular cap sized to attach to said distal portion of said double walled cylindrical tube, an insulation layer between said internal wall and said external wall of said double walled cylindrical tube, and a heating element enclosed within said central cavity and thermally coupled to said insulation layer.

  • the proximal end 8 of the double walled cylindrical tube 3 is closed and has a protrusion 9 extending into the central cavity 4 towards the distal end 7 of the double walled cylindrical tube 3, sized and shaped to receive the lens portion 2 of the optical instrument 1.
  • the protrusion 9 is preferably a cylindrical protrusion located about the central portion of the proximal end 8 of the double walled cylindrical tube 3.
  • the central cavity 4 is filled with a conductive heating element
  • a non-woven cleaning member 12 made from acrylic, polypropylene or other appropriate filter type material may be disposed at the distal end 14 of the cylindrical protrusion 9 such that when the lens portion 2 of the laparoscope 1 is inserted into the cylindrical protrusion 9, the lens portion 2 contacts the cleaning member 12.
  • a similar cleaning member may be provided in any one of the embodiments of the lens warming device as described herein.
  • the lens warming device 39 may have a flexible grommet 40 made from a plastics based material such as silicon attached at the proximal end 41 of the cylindrical protrusion 42.
  • the flexible grommet 40 enables optical instruments 1 of differing sizes to be inserted into the cylindrical protrusion 42 whilst providing a degree of support for the optical instrument 1.
  • the cross-section of the cylindrical protrusion 42 may comprise a plurality of decrementing steps extending from the proximal 41 to the distal portion. This will provide increased support for the optical instrument 1 when it is inserted into the insulated lens warming device 39.
  • the lens warming device 39 is of a similar double cylindrical construction as described above with reference to Figure 1.
  • the insulated lens warming device 30 may have a handle 1 1 of preferably L-shaped configuration, attached to the upper surface 8 of the insulated lens warming device 30.
  • the handle 1 1 is preferably an integral part of the insulated lens warming device 30 formed during the plastics moulding process however other attachment techniques may be employed such as ultrasonic welding, gluing or other appropriate attachment mechanism.
  • the handle 11 provides a means for transporting the insulated lens warming device 30 around the operating environment as well as providing a means for removably attaching the insulated lens warming device 30 to surgical drapes or table.
  • the handle 1 1 may comprise a handle clip type mechanism which opens and closes such that the insulated lens warming device 30 can securely grip onto the surgical drapes or table.
  • any of the embodiments described herein may be provided with a handle as described above in relation to Figure 2.
  • the insulated lens warming device 30 Prior to use, the insulated lens warming device 30 is placed in a microwave or other conventional oven type surgical warming device in order to raise the temperature of the heating element 15 to a temperature above ambient body temperature.
  • the cleaning member 12 may then be inserted toward the distal portion 14 of the cylindrical protrusion 9.
  • the lens portion 2 of the laparoscope 2 is then inserted into the cylindrical protrusion 9 such that the lens portion 2 may contact the cleaning member 12.
  • the thermal energy produced by the heating element 15 warms the lens portion 2 to a temperature above ambient such that the lens portion 2 becomes warm enough to prevent lens condensation on insertion of the lens portion 2 into a body cavity while the cleaning member 12 may clean the lens portion 2 in preparation for surgical use.
  • the insulation layer 6 is in thermal contact with the heating element 15 such that the heating element temperature is maintained for at least the duration of the surgical procedure. Therefore, when the lens portion 2 is removed from the body cavity, it can be re-inserted into the insulated lens warming device 30 to maintain the temperature of the lens portion 2 to at least above ambient. Also, when the cleaning member 12 is inserted into the cylindrical protrusion 9 the lens potion 2 may also be cleaned in preparation for reinsertion into the body cavity.

  • the walls 20 of the cylindrical protrusion 44 may be impregnated during the plastics moulding and forming process with a black coloured material such as dye.
  • the insulated lens warming device 43 is not pre-heated prior to use as the light source emanating from the lens portion 2 of the optical instrument 1 strikes the distal portion 14 of the cylindrical protrusion 44 and being coated black, absorbs the light energy and converts it to thermal energy due to conduction.
  • the thermal energy therefore warms the lens portion 2 of the optical instrument 1 up to above the dew point of the insufflation gas used within the body cavity thus preventing lens fogging.
  • a removable black plastic moulded insert 21 of preferably cylindrical cross-section, having a closed distal end 22 may be inserted into the cylindrical protrusion 44.
  • the black insert 21 provides an alternative means of converting light energy into thermal energy due to conduction using the light source emanating from the lens portion 2 of the optical instrument 1.
  • An insulated lens warming device of the third embodiment of the present invention is shown in Figures 5 and 6.
  • the lens warming device 31 here has two gas tubing connectors 23, 24 in fluid connection with the double walled cylindrical tube 32.
  • the input gas tubing connector 23 is located towards the proximal portion 33 and the output gas tubing connector 24 is located towards the distal portion disposed at substantially 180° to each other, penetrate the body of the double walled cylindrical tube 32.
  • a gas tube supplying heated and preferably humidified gas from the same source used to insufflate the body cavity is diverted and attached to the input gas tubing connector 23 thus inserting at least heated gas into the central cavity 34.
  • the resultant thermal energy generated within the central cavity 34 raises the temperature up to above the dew point temperature of the gas.
  • the thermal energy generated will increase the temperature within the cylindrical protrusion 35 such that when the lens portion 2 of the optical instrument 1 is inserted into the cylindrical protrusion 35 the lens portion 2 absorbs the thermal energy heating the instrument prior to insertion into the body cavity thus preventing lens fogging.
  • the gas can exit from the central cavity 34 via the output gas tubing connector 24 located towards the distal portion 36 of the insulated lens warming device 31. There is no requirement to attach a gas tube to the second gas tubing connector 24 as the gas is allowed to exit to free air space.
  • the lens warming device 37 preferably has a whitening insert 26 disposed at the distal end 38 of the cylindrical protrusion 45.
  • the whitening insert 26 may be inserted into the cylindrical protrusion 45 prior to the insertion of the lens portion 2 of the optical instrument 1.
  • the optical instrument 1 is switched on such that light emanates from the distal portion of the optical instrument 1.
  • the lens portion 2 is then inserted into the insulated lens warming device 37.
  • the lens warming device 37 is similar to that of that of Figure 1 in that the lens warming device 37 has a double walled cylindrical tube construction 46.
  • a cavity 27 may be formed during the plastics moulding process to provide an opening extending from the double walled cylindrical tube outer surface and inner surface, across the distal portion of the cylindrical protrusion (not shown, but similar to 45 in Figure 7) towards the opposite inner surface wall.
  • a removable whitening block 28 may be inserted into the double walled cylindrical tube cavity 27 opening such that when the lens portion 2 of a optical instrument 1 is inserted into the insulated lens warming device 47 the scope can be calibrated and warmed prior to insertion into a body cavity. This is achieved by switching on the optical instrument light source such that the lens portion 2 of the optical instrument 1 receives light reflections off the whitening block 1.
  • the general construction of the lens warming device 47 is similar to that of that of Figure 1 in that the lens warming device 47 has a double walled cylindrical tube construction 48.
