Definitions

  • Such apparatus may include a hand grip 12 to be gripped by the palm and lower three fingers of a single hand of an operator; an actuator 14 mounted slidably on top of the hand grip for sliding, reciprocating, trans- ' lating movement with respect thereto; an internal suction tube 16 having its rearward portion secured to the hand grip 12 such as by being threadedly engaged therewith as indicated in FIGS. 4 and 5, and an external control tube 18 coaxially surrounding the internal suction tube 16 and having its rearward portion threadedly secured to the actuator 14 for sliding, reciprocating, translating movement with the actuator 14 and with respect to the hand grip 12 and the internal suction tube 16.
  • the plurality of radially disposed suction holes 23 defining the entrance aperture 20 may be axially disposed such tha the smaller holes are more forward of the suction tube 16 and the larger holes are more rearward of the suction tub Accordingly, it will be understood that upon the control tube 18 being moved forwardly the suction may be focused at the end of the suction tube 16 by exposing only the smaller suction holes 23 or even portions thereof; con ⁇ versely, upon the control tube 18 being moved rearwardly the number and size of the radially disposed suction hole 23 exposed are increased and the suction provided is accordingly increased.
  • filter element 118 is a generally cylindrical member having a .cylindrical wall
  • filter element 118 is provided with an entrance aperture which in the embodiment shown comprises a plurality of suction holes 150 which are sized and positioned in the same manner and for the same purposes as are discussed above wi respect to suction holes 23 of the embodiment of FIGS. 1 through 6. Further, filter element 118 is provided with a longitudinally ex ⁇ tending ridge 151 disposed on its outer surface. Ridge 151 coopera with cutter blade 116 to preclude rotation thereof relative to the -filter all as discussed below in detail.
  • Coil spring • 168 is sized in compression characteristic and length to exert a resistance to displacement of actuator 114 to the left as seen in FIGS. 5, 6 and 7, and to return actuator 114 to the position shown in FIGS. 5 and 7 upon release of trigger pressure.
  • cutter blade 116 comprises a generally thin cylindrical member having split 169 ex ⁇ tending axially throughout its length.
  • the cutter blade 116 is provided with spring fingers 162 for cooperating with annular groove 161 to secure the blade within the end of control tube 122.
  • Blade 116 is also provided with a machined cutting edge 179 which as shown, is angled outwardly and rearwardly from the end of filter element 118.
  • Thumb piece mounting section 156 comprises grooves
  • Such grooves define locking means which receive spring fingers which are formed on inner surfaces of thumb piece
  • Dimple 174 is in axial alignment with detent 125 formed in the upper surface of hand grip 124 such that if actuator 114 is displaced from right to left as shown in FIGS. 7-9 by an amount sufficient to cause dimpl 174 to overlay detent 125, actuator 114 is retaine in the leftward or suctioning position until forced to the right by the exertion of pressure against thumb piec 172. The amount of force required to displace actuator
  • clogging occurs from time to time. Such clogging may be the result of bone chips being caught in suction holes 150 or from any of a number of other reasons. This does not present a major problem in the operation of apparatus 110. More specifically, if a surgeon re ⁇ leases trigger 154 and spring 168 has insufficient force to cause trigger section 114 to return to the position shown in FIG. 5, then the surgeon may exert pressure on thumb piece 172 to manually displace . actuator 114 to the desired position.
  • Such pressure on thumb piece 172 generates a corresponding force on the cutting edge 170 of cutter 116 so as to sever whatever material is clogging suction holes 150 thereby to re-establish an unim ⁇ peded path for the flow of fluid and other materials through suction holes 150.
  • Apparatus 110 may be manufactured using well known manufacturing techniques and materials which have been recognized in the art to be suitable for these purposes.

Abstract

Appareil d'aspiration chirurgicale pour aspirer des debris chirurgicaux pour nettoyer une plaie chirurgicale et comprenant une structure de nettoyage des debris chirurgicaux logee a l'ouverture d'entree de l'appareil et pouvant etre utilisee pour modifier la dimension de l'ouverture d'entree de maniere a modifier l'aspiration appliquee sur les debris chirurgicaux. L'appareil chirurgical contient plusieurs trous d'aspiration disposes radialement (23, 150) et axialement de sorte que les trous d'aspiration les plus petits se trouvent dans la partie avant d'un organe cylindrique pour former un filtre. Des trous d'aspiration plus grands se trouvent sur la partie arriere du cylindre de sorte qu'en coulissant en avant un second tube (18) le nombre et la dimension des trous d'aspiration radiaux diminuent reduisant ainsi le niveau d'aspiration applique et focalisant l'aspiration a l'extremite avant d'un premier tube (20). Un second tube (18, 122) coulisse par rapport au premier tube (16, 120) en appliquant une force sur la poignee (24, 172) de maniere a augmenter ou diminuer le nombre et la dimension des orifices d'aspiration radiaux.
