Definitions

  • This invention is directed to an apparatu and to a method. More specifically, this invention concerns an improve composite suction/irrigation probe for use in conjunction with hydrodissection apparatus, and to a method involving concurrent infusion an suction of hydrodissection fluid.
  • Hydrodissection procedure typically involve directing a pressurized fluid stream at a target tissue throug a probe, followed thereafter by suction of the fluid from the operative fiel through the same probe; or, through a probe connected to a separat instrument.
  • This procedure as practiced with a symmetrical valve (i.e trumpet valve) of the type disclosed in the co-pending application serial no 07/470/771 filed on January 26, 1990, simply involves the sequentia depression of the irrigation piston connected to the source of th hydrodissection fluid, release of the irrigation piston, which discontinues th flow of fluid, depression of the suction piston to effect aspiration of flui from the operative field, and the repetition of the above sequence.
  • the sequential infusion of hydrodissection fluid, followed, thereafter by suction through the same probe prolongs the operative procedures.
  • the probe tip ma become fouled with tissue fragments, blood and the like, thereby interruptin the fluid aspiration process and possibly requiring withdrawal of the prob from the operative field, its replacement and thereafter the resumption of th operative procedure by reinsertion of the probe into the patient's body.
  • a symmetrica valve body having at least one pair of valves, one member of said pai connected to a source of pressurized fluid and the other member of said pai connected to a source of negative pressure (vacuum).
  • the symmetry of th valve body allows for connection of a probe tip at either of one or tw diametrically opposite positions to accommodate clinician preference (righ handed versus left handed operation).
  • a composite probe tip is herein provided to attach to the valve body t each of two mounts on the valve body designed for this purpose.
  • Thi composite probe includes an outer, or suction, barrel and an inner, o irrigation, barrel, each of which is operatively connected to a different moun on the valve body, however, oriented in a common direction. Mor specifically, the orientation (mounting) of the suction barrel relative to th valve body is based on clinician preference (right hand versus left hand i operation); and, the irrigation barrel connected to the opposite mount.
  • the irrigation barrel is designed fo attachment thereof to the valve body so as to orient it in the same direction a the suction barrel, by passing the irrigation barrel through the valve body an thereby extending down through the suction barrel where it ultimatel protrudes from a hole in the tip (distal end) of the suction barrel.
  • Thi composite probe thus allows for allowing irrigation of the operative fiel concurrent with the aspiration of fluid therefrom.
  • the irrigation barrel is further provided at it proximal end with complimentary connector for sealing engagement of the valve body at th point where it is connected to the mount.
  • an opening is positioned on the side of the barre ⁇ / approximately coincident with an opening in the valve chamber which supplies the pressurized source of irrigation fluid to the barrel, thus, affording flow of irrigation through the composite probe to the operative field.
  • a source of suction is connected to the valve body so as to permit the introduction of negative pressure at the tip of the suction barrel upon movement/depression of the piston within a valve chamber operatively connected to the source of negative pressure; and infusion of pressurized fluid to the tip of the irrigation barrel upon movement/depression of the piston wit-hin a chamber operatively associated with a source of irrigation fluid.
  • each of the source of negative pressure and pressurized fluid are isolated by one another within the valve body by the "O" ring seal on the irrigation barrel, it is possible to depress either one or both pistons concurrently and thereby infuse fluid into the operative field and aspiration thereof within a single symmetrical mstrument.
  • the inner (irrigation) barrel can have a variety of tip configurations. - In the most preferred embodiment to this invention, the probe tip is tapered. It is also contemplated that the respective functions of each member of the composite probe be reversed simply be reversal of the connection of the pressurized source of irrigation fluid and negative pressure to the valve body.

  • the irrigation control valve of this invention comprises a valve housing or body within which are formed two cylindrical valve chamber.
  • the housing of the control valve is further equipped with a pair of fittings (20a, 20b) for each chamber which defines a conduit (22a, 22b).
  • the fitting can be connected to a source of vacuum or a source of irrigation fluid.
  • These conduits (22a, 22b) provide communication between the source of vacuum and/or irrigation fluid and the interior of the valve chamber which is formed within the body of the control valve.
  • the valve chamber is essentially uniform in diameter and of a defined length.
  • the valve body defines two interior cylindrical chamber (18a, 18b), each of which is essentially the same in both dimension and in its contemplated operation. Each such chamber is of a defined length.
  • the fitting or inlet port on the valve body defines a conduit which terminates as an inlet orifice (24a, 24b) in the chamber wall (26a, 26b).
  • the chamber wall is provided with yet a second orifice (28a, 28b), offset from the inlet orifice. This second orifice provides for communication between the interior of the chamber and a conduit (30) which is at right angles to the orientation of the chamber.
  • Tfhis conduit (30) can also be positioned on the same side of the valve body as the inlet orifice (24a, 24b) to enhance the ergonomics in the valve design.
  • This conduit is provided on either end with a fitting (32a, 32b) adapted to connect to a probe (not shown).
  • Each of the valve chambers within the valve body is further provided with a piston (34a, 34b). As more fully illustrated in FIGS. 2, 3 and 4, these pistons are designed for reciprocating movement within the cylinder. In order to provide for watertight and airtight operation, these pistons are each equipped with a series of seals (36a-c, 38a-c). Each piston is further provided with an oval opening (40a, 40b) approximately equivalent in width to the orifices in the chamber wall.
  • the length of the piston is such as to allow reciprocating movement within the cylindrical chamber and accommodation of spring bias means (not shown) within the cylinder chamber between the base of the piston and the bottom of the cylindrical chamber. The spring bias means is intended to maintain the valve in the closed portion.
  • the seals which are located both fore (36a, 38a) and aft (36b, 38b) relative to the oval opening (40a, 40b) in the piston prevent fluid from inadvertently flowing from the source of irrigation fluid to the common conduit.
  • the oval opening in the piston aligned to permit communication between the inlet orifice and the orifice to the common conduit, fluid will begin to flow therebetween.
  • the seal at the base of the piston ensures against fluid being trapped between the base of the piston and the base of the valve chamber which, if not vented, could prevent depression of the piston within the chamber.
  • FIG. 5 illustrates the relative positioning of the two orifices within each cylinder wall and the contemplated direction of flow of fluid upon reciprocal movement of the piston to allow for such flow.
  • a conduit is connected to each of the fittings on the valve body.
  • the conduit can be connected to either a source o irrigation fluid or to a source of vacuum.
  • the conduit is connected to a source of irrigation fluid.
  • FIG. 6 illustrates, in cross-section, a composite probe (50) of this invention installed on the trumpet valve of Fig. 1.
  • each of the probe mounts (30), on the body of the irrigation valve are initially exposed.
  • the outer or suction barrel (60) N of the composite probe is installed first.
  • the position of the suction barrel on the valve body is determined by clinician « preference: more specifically, the preference of the clinician for right handed or left handed operation.
  • the inner or irrigation barrel (62) is thereafter put in place.
  • the orientation of the inner or irrigation barrel, relative to the valve body (12) is determined by the orientation of the outer or suction barrel. As illustrated in Fig.
  • the inner or irrigation barrel is mounted so as to pass through the valve body (12) and extend down the outer barrel of (60) the composite probe (50), with the tip (64) of the inner probe (62) extending through a port (64) in the distal end of the outer barrel designed to accommodate it.
  • the inner probe is provided with a fitting (70) to seal the mount at the proximal end of the probe to the mount on the valve body.
  • the side wall of the inner barrel is provided with a slot or opening (72) which is in approximate alignment with the opening in the valve chamber operatively connected to a pressurized source of irrigation fluid.
  • an additional flexible seal in the form of an "O" ring (74) is positioned and fixably mounted on the inner barrel approximately equidistant between each of the valve chambers so as to separate each of the chambers from one another.
  • each of the valve chambers are operatively connected to only one of the functional components of the composite probe. More specifically, upon simply the depression of the piston (76) associated with the suction chamber (78) as illustrated in Fig.
  • FIG. 8. illustrates in greater detail the inner barrel (62) of th composite probe. More specifically, the proximal end (90) of such probe i provided with means for attachment to the valve body in the form of a treade fitting (92). As noted above, a slotted opening (72) is provided in the sid wall to allow for infusion of fluid throush the side wall into the commo channel (86) of the irrigation probe. In the preferred embodiments of thi invention, the slotted opening provides a orifice through the valve to allow fo infusion of fluid from either side of the barrel. In the configuration of prob tip illustrated in Fig. 6, a raised collar (94) is machined into the probe tip t provide a means for support and retention of a flexible seal.
