Definitions

  • This invention relates to a nozzle for surgical suction apparatus.
  • Surgical suction devices are used for a number of purposes in surgery.
  • One use of these devices is to suction fluids, such as wound fluids and irrigation solutions, trauma debris and tissue debris from the wound or surgical area of the patient.
  • the suction device is normally terminated in a suction nozzle of some kind that is connected, via a flexible tube, to the suction apparatus itself.
  • An example of such a nozzle is a simple device known as a Yankauer.
  • This device normally consists of a tube that is tapered at the patient end and formed with a suction opening.
  • the Yankauer is easily manoeuvred in the surgical area and various sizes of Yankauers are available.
  • Suction control is exercised by means of a finger control aperture, the effective opening of which is varied by the practitioner moving a finger to close, open or partly open the aperture.
  • a nozzle for a surgical suction device comprises a suction tube that is adapted for connection to the suction device at the one end of the tube and for location in the surgical area of a patient at its other end, the nozzle including suction control means intermediate the ends of the tube, which control means includes a finger controllable suction control aperture in fluid communication with the interior of the suction tube and a filter constituted by a gas permeable, liquid impermeable membrane.
  • suction control is exercised by the practitioner moving a finger to close, open or partly open the finger controllable suction control aperture.
  • the membrane is intended not to interfere significantly with air flow through the finger control aperture. To this end, the membrane must be gas permeable to permit the passage of air into the suction tube.
  • the membrane must, however, prevent the egress of liquids such as wound fluids from the aperture in order to be effective in preventing or at least minimising contact between the practitioner's finger and fluid entrained in the air flow through the suction tube. To this end, the membrane must be liquid impermeable.
  • membranes examples include microfilters and hydrophobic filters with appropriate pore sizes.
  • the membrane may be discrete from and secured to the tube, in which case it could be incorporated in a discrete insert that is adapted to fit onto the nozzle over the suction control aperture.
  • the membrane may be formed integrally with the tube.
  • the invention includes a method of operating a surgical suction device nozzle comprising a suction tube adapted for connection to the suction device at the one end of the tube and for location in the surgical area of a patient at its other end, the nozzle including suction control means intermediate the ends of the tube, which control means includes a finger controllable suction control aperture in fluid communication with the interior of the suction tube, the method including the steps of locating a filter comprising a gas permeable, liquid impermeable membrane over the control aperture.
  • Figure 1 is a side elevation of a Yankauer incorporating the invention
  • Figure 2 is a partial cross-sectional side elevation on the suction control aperture of the Yankauer of Figure 1;
  • Figure 3 is a diagrammatic isometric view of a Yankauer and a plug therefore according to the invention.
  • the suction aperture of the Yankauer tube is often blocked by contact with the soft tissue in the surgical area. This is because the suction aperture of the tube is forward facing and the rim of the aperture tends to make suction contact with the soft tissue in the surgical area drawing the tissue partly into the tube and blocking the tube. Manual manipulation of the tube end in the surgical area is then required to relocate the tube if the suction efficiency of the suction apparatus is to be restored.
  • the end of the Yankauer tube is formed with a plurality of small apertures adjacent the patient end of the tube.
  • the Yankauer tube also includes a suction control aperture intermediate the ends of the tube that permits finger control of the suction applied at the suction aperture.
  • a suction control aperture intermediate the ends of the tube that permits finger control of the suction applied at the suction aperture.
  • the size of the suction control aperture is merely varied by the practitioner, using a finger to open or close the aperture to a greater or lesser extent.
  • suction in the Yankauer tube is broken simply by opening the suction control aperture to permit air being drawn into the suction control aperture.
  • suction controls provide only indirect suction control. They lack the fine control that is possible with the more natural control exhibited by a finger controllable suction tube.
  • the control action is achieved by means of the perfectly natural and intuitive movement of pressing the finger down onto the suction control aperture to a greater or lesser degree .
  • This invention aims to address these problems and it will be described with reference to a conventional suction nozzle or Yankauer 10, 100 as is illustrated in the drawings .
  • the Yankauer 10 of Figure 1 comprises a connector tube 20 in fluid communication with a curved suction tube 50 that extends from the connector tube 20.
  • the connector tube 20 and suction tube 50 may be integrally moulded or, as is illustrated, they may be formed in two parts and glued together.
  • the connector tube 20 is formed with an externally ribbed connector 22 located distally of the free end of the suction tube 50.
  • the connector 22 is dimensioned to fit tightly within conventional surgical suction hoses.
  • the connector tube 20 is provided with grip formations 24 along its sides.
  • the suction tube 50 is provided with a forward facing suction aperture 52 at the free end thereof.
  • Two pairs of opposed suction relief apertures 54 are formed adjacent the free end of the suction tube 50.
  • a raised lip or ridge formation 26 encloses a suction control 40.
  • the suction control 40 is shown to include a suction control aperture 42 that is open to the suction passage within the connector tube 20.
  • the upper end of the aperture 42 is fitted with a filter membrane that covers the entire area of the aperture 42.
  • the filter membrane is constituted by selectively permeable membrane 44 that is seated on a peripheral shoulder 26.2 formed internally of the ridge formation 26.
  • the Yankauer 100 comprises a unitary tube 110 having tapered ends constituted by a suction end 150 and a connection end 120, the latter end being tapered for insertion into a conventional suction hose.
  • the Yankauer 100 may conveniently be blow moulded, extruded or injection moulded in plastics.
  • Suction control is normally exercised by means of a conventional suction control aperture 142.
  • a filter membrane 144 is incorporated in a plug 125 that is adapted to fit into the suction control aperture 142.
  • the plug 125 is a friction fit in the aperture 142.
  • the membranes 44, 144 are gas permeable, liquid impermeable membranes which, in use, would permit the passage of air into the suction passage and prevent the egress of wound fluids from the suction passage.
  • the most convenient filter membrane would be constituted by an air permeable, hydrophobic material, a number of which are known.
  • the finger control apertures 42, 142 of the Yankauers illustrated in the drawings are dimensioned to be closed by the tip of a finger, even with the membrane-covered plug 125 covering the control aperture 142 of the Yankauer 100 of Figure 3.
  • the Yankauers 10, 100 are secured to the end of a conventional suction hose of a surgical suction apparatus and held firmly by the practitioner using middle finger and thumb with the tip of the index finger over the suction control aperture. The Yankauers 10, 100 are then used in the conventional manner to suction wound fluids and wound debris from the surgical area of the patient.
