Definitions

  • a trochar tube having a slidable stylet therein with a pointed inner or distal end for facilitating insertion through the incision and thereafter adapted to be retracted into the tube to prevent contact with and possible damage to the bladder
  • a slidable button or finger operated member carried by the trochar tube for moving the stylet and also for rotating a valve, communicating the eye or opening in the distal end with a cannula or tube.
  • the present invention serves a purpose like that of the device referred to but provides certain improvements thereover, and also provides a device which may be more economically manufactured due to elimination of certain parts.
  • no wing expanding spring is employed, the inherent resilience of the wings now serving the purpose of the spring; the conical tip is an integral part of the stylet and may be retracted to a position inside of the distal end of the trochar tube; and the valve is a part of the device, rather than an at tachment thereto.
  • the device comprises only three parts which may be formed by injection moulding techniques.
  • the device may be expendable after a single use, obviating dismantling, cleaning, and resterilization, all of which consume valuable time. It is thus contemplated that the device may be furnished, if desired, in a sterile package, used once, and then discarded, analogous to present practice employed in the use of throw-away hypodermic needles.
  • the stylet is also connected to its actuator button and valve with a snap fit which, after being connected, prevents disconnection of these parts, encouraging discard of the device after a single use, rather than an attempt to dismantle for thorough cleaning, which, as will be apparent, is in the interests of always employing an unused and sterile device, which, of course, is possible by reason of the simplicity of parts and low cost of manufacture.
  • FIG. I is a longitudinal central section through the subject of the invention.
  • FIG. 1A is a like section, illustrating a different position of parts
  • FIG. 2 is a section taken on line 2-2, FIG. 1;
  • FIG. 3 is a section taken on line 33, FIG. 1A;
  • FIG. 4 is a side elevation of an operating button and valve.
  • tro'cha'r tube is of circular configuration formed of plastic material by injection moulding techniques.
  • Angularly spaced wings 12, such as four, are separated by longitudinal slots 14 therebetween and the wings are normally in expanded position as shown in FIG. 1A, tending toremain thereat due to their resiliency.
  • a circular flange 16 is disposed intermediate the ends of the tube to provide an abutment for the forefinger and middle finger of the operator.
  • the proximate end is provided with a cylindrical bore 18 which, on occasion, may communicate with a tube 20 to which a flexible tube or cannula (not shown) may be affixed.
  • the operating button 22 is provided with a pair of arcuately shaped sliding portions 24,24 which fit the bore and, upon rotation of the button, open or close communication between bore 18 and tube 20.
  • the operating end of the button and valve which may be engaged by the thumb of the operator, is provided with a member 26 with an integral resilient hinge 28 which urges member 26 radially outwardly.
  • free end 32 of member 26 is disposed in a position where it may abut tube end 34 unless member 26 is depressed to clear same. When so depressed it may then be moved inwardly of the bore, as shown in FIG. 1.
  • An O-ring 36 prevents outward leakage from the bore and around button 22.
  • a pair of resilient lugs 38,38 are integrally formed on button 22, which may spring apart in opposite radial directions.
  • the opening therebetween is cylindrical with a diametrical slot 40 and shoulders 42 are provided adjacent a recess 44 disposed inwardly of the free ends of the lugs.
  • stylet 46 is provided with a frusto-conical head 48 and a groove 50 adjacent the large end thereof forming a neck portion 52 which rotatably fits within the bore of the lugs.
  • the parts are forced toward each other in the axial direction and the taper of the head forces the lugs radially outwardly.
  • the large end of the conical head reaches the inner end of the lugs they snap back to their original position, thus capturing the head in recess 44.
  • this is similar to a barb on a hook which permits it to enter but not to retract.
  • the remainder of the stylet is essentially a circular rod with guiding and supporting fins 56 and a conical distal head portion 58.
  • member 26 with the stylet in place is first depressed to permit it to enter bore 18 and slide therein. Thumb pressure on the free end of the button then moves the stylet relative to the tube until lugs 60 engage the ends of slots 14. When lugs 60 abut the ends of the slots they then collapse the wings 12, head portion 58 now being exposed and beyond the distal end of the trochar tube. When in this position the trochar tube is inserted through the incision. A slight rearward pull force on the button now releases lugs 60 from the front ends of the slots and the wings expand from the position shown in FIG. 1 to that of FIG. 1A.
  • button 22 When it is desired to communicate slots 14 with tube 20, button 22 is rotated to move one of the arcuate portions 24 out of registry with tube 20.
  • a device in accordance with claim 4 including 1.
  • a device in accordance with claim 7 including an O-ring carried by the operating member engageable with a bore in the trochar tube and means adjacent thereto for providing said trochar tube with a selective fluid discharge means.
  • the construction and arrangement being such that when said wings are collapsed adjacent the stylet said tip is extended beyond the distal end of the trochar tube, the tip aiding in inserting the trochar tube through an incision,
  • an incision trochar tube and its wings are integrally formed of inthrough an abdominal wall and into a bladder, and jection moulded material and the stylet is formed as an the tip, when retracted being enclosed within the integral member, the device thus comprising four parts trochar tube preventing its contact with and consisting of: the trochar tube, the stylet, the operating damage to an organ within which it is disposed, member, and the O-ring.
