  • FIGURE 27 is an end view as Seen when viewed in the direction of line 27-27 of FIGURE 26.
  • FIGURES 1, 2, 3, and 20 illustrate a medical stapler generally indicated at 21 comprising a pair of forceps with a driver arm 22 terminating in a driver 23 and an anvil arm 24 terminating in an anvil 25.
  • These arms 22, 24 are movable toward and from each other for driving a staple 26, that is held in a cartridge 28 above the anvil 25. Both arms are provided on the exterior with knurlings 30 for easiermanual grasping.
  • a cartridge holder 32 is secured to the driver arm 22 by a leaf spring 34.
  • Each of the arms 22 and 24 is resilient and forms leaf spring, the arms in their normal position being spread apart as shown in FIGURE 1.
  • a limit stop 36 bridges a slide 38, the function of which will be described below, and is secured to the cartridge holder 32.
  • the upward movement of the upper arm 22 relative to the cartridge holder 32 is limited by the head 40 of a screw 42 which extends through a notch 44 in the stop 36. By this means the driver arm 22 is pre-tensioned.
  • the lower arm 24 of the forceps 21 terminates in an anvil 25 provided with two clinching grooves 27 and 29.
  • the cartridge holder 32 is constructed with two prongs 45 and 47 spaced to frictionally engage two lateral grooves 49 and 51 on the staple cartridge 28.
  • the slide 38 is held against the upper surface of the cartridge holder 32 by the shoulders 53 and 55 on the limit stop 36, and movement of the slide is limited to a direction parallel to the longitudinal axis of the cartridge holder by the projection 52, which slides between the prongs 45 and 47.
  • the slide is normally retained in its forward position, illustrated in FIG- URE l, by the tension of the spring 54 which holds the shoulders 57 and 59 of the slide 38 against the back surface of the limit stop 36.
  • the staple cartridge which may be molded of plastic, is constructed with a centrally-located pusher channel 60 that extends from the back end 62 of the cartridge to opposite parallel staple grooves 63 and 65 at the forward (dispensing) end thereof; the parallel grooves being formed by the side walls of the channel 60 and the walls of the parallel shoulders 77 and 79. Said shoulders are perpendicular to the longitudinal axis of the cartridge and the channel.
  • the cartridge is formed with an integral center piece 64 at the forward end of the channel, the face 66 of which is disposed between the grooves 63 and 65 and is parallel with the inner surfaces of the shoulders 77 and 79 being displaced therefrom by a distance equal to the thickness of a single staple.
  • the thickness of a staple' is determined by the diameter of the wire used to form the staple, i.e., about 6-9 mils.
  • Located within the channel of the cartridge is a plurality of miniature staples, each having two legs 67 and 69 connected by a crown 68 (see FIGURE 19).
  • the series of staples within the channel are in parallel alignment with the crown of each staple in frictional contact with the top surface 70 of the channel, the free ends 71 and 73 of each staple being in frictional contact with the tip guides 61 and 72 and pointing in a direction perpendicular to the longitudinal axis of the cartridge.
  • a U-shaped staple pusher 74 is provided having a crosssection that conforms with the cross-section of the staples and the channel.
  • the pusher is slidably movable Within the channel in the direction of the longitudinal axis of the cartridge and is in registry with the series of staples contained therein. Movement of the staple pusher toward the forward end of the cartridge forces the series of staples forward so that the first staple 26 of the series is forced against the outer walls 77 and 79 of the parallel grooves.
  • a projection 80 extending from the top surface 82 of the cartridge has a forward face 84 which is parallel to the shoulders 77 and 79 and in vertical alignment with the rst staple 26.
  • the projection 80 engages the driver 23 as shown in FIGURE 9 and serves the dual function of retaining the cartridge on the cartridge holder against the pressure of the spring 54, and aligning the cartridge and the staple 26 with the driver and anvil.
  • the vertical surfaces 81 and 82 at the forward end of the cartridge are spaced apart a distance slightly greater than the width of the driver 23 and prevent lateral movement of the driver as it descends to drive the staple.
  • Staple alignment markers 83 and 85 may be provided on the forward edges of the cartridge to assist the surgeon in lining up the instrument and cartridge with the tissue to be stapled. As shown in the drawings, serrated gripping 4 surfaces 86 and 88 may be provided at the rear of the cartridge where obstruction of the surgeons view is not a problem.
  • the staple pusher 74 is forced against the projection 52 of slide 38 and moves it in the direction of the arrow against the tension of the spring 54.
  • the driver 23 is forced upward by the inclined surface of the projectiOn 80 at the forward end of the cartridge, returning to its normal spread-apart position as indicated in FIGURE 9 after the edge 84 of the projection has passed the end of the driver.-
  • the cartridge may then be released, as it will be held in a fixed position by the tension of the spring 54 which forces the edge 84 of the projection 80 against the driver 23.
  • Angular movement of the cartridge with respect to the cartridge holder is prevented by the prongs 45 and 47 of the holder which engage the longitudinal grooves 49 and 51 on the cartridge.
  • the lower arm or anvil spring 24 is weaker than the pretensioned driver spring 22, so that when the surgeon presses the two arms 22 and 24 toward each other, the anvil 25 will first move upward to a position that is shown in dotted lines in FIGURE 9. This enables the surgeon to grasp the tissue between the anvil and the lower surface of the cartridge before driving the staple.
  • Each staple of the series is in frictional contact with the top surface 70 and the side walls and 76 of the channel 60. As the driver 23 clears the top surface 70 of the channel, the next staple in the series is pushed between the top surface of the channel 70 and the upper surface yof the center piece 64 against the shoulders 77 and 79 beneathV the driver 23 in position for driving. It will be apparent from the above that during the use of this instrument, there will always be a staple suspended between the driver and anvil'until the supply of staples in the cartridge has been used up.
  • FIGURES 21 and 22 a modified stapling instrument of the scissors type, which differs from the medical stapler described above, in the shape of the forceps and accordingly in the location of the fulcrum 120. It will be noted that in most other respects the multiple stapler dispenser of FIGURES 21 and 22 resembles that of FIGURES 1-7 and functions in a similar manner. For the parts that are alike, there will therefore be used herein the identical reference numerals, while merely corresponding parts have different prefix numerals.
  • the modified medical stapler illustrated comprises a scissors type of forceps with a driver arm 122 terminating in a driver 23 and an anvil arm 124 terminating in an anvil 25.
  • Finger grips 102 and 104 at the opposite ends of the arms 122 and 124 facilitate precise positioning and operation of the stapler deep within a body cavity.
  • These arms 122, 124 are movable toward and from each other about the fulcrum 120 for driving a staple that is held in a cartridge 28 above the anvil 25. f.
  • a cartridge holder 32 is secured to the driver arm 122 by a spring 134.
  • a limit stop 136 is secured to the cartridge holder 32 and bridges alslide 38, the function of which has been described above.'
  • the upward movement of the upper arm 122 relative to the cartridge holder 32 is limited by the stop 136.
  • the tensiOn of the spring 134 normally retains the driver and cartridge holder in the spread-apart position shown in the drawings. By this means the driver arm 122 is pretensioned.
  • the stop 136v also limits the distance between the cartridge holder 32 and the driver 23 and assures that the cartridge will be retained on the holder by the pressure of the driver against the face 84 of the cartridge projection 80.
  • the cartridge holder 32 is constructed with two prongs 45 and 47 spaced to frictionally engage the lateral grooves 49 and 51 on staple cartridge 28.
  • the slide 38 is held against the upper surface of the cartridge holder 32 by the shoulders 153 and'155 on the limit stop ,136, and movement of the slide is limited to a direction parallel to the longitudinal axis of the cartridge holder bythe projection 52, which slides between the prongs 45 and 47.
  • the slide is normally retained in its forward position, illustrated in FIGURE 22, by the tension of the spring 54.
  • Cartridges for use with ⁇ the stapler modified as shown in FIGURES 2l and 22 are identified in all respects with the cartridge described above and illustrated in FIGURES -20.
  • the cartridge is preferably disposable and may be made of plastic or other inexpensive material that lends itself to being sterilized,v such as, for instance plastic known under the trademark Delrin.
  • the operation of the modified instrument is similar to that of the one previously described.
  • a sterile staple cartridge is slipped on the cartridge holder, past thedriver, and released.
  • the spring-biased slide will hold the face 84 of the cartridge projection 80 against the inside surface of the driver, properly positioning the cartridge on the holder with the first staple directly under the driver.
  • the surgeon grasps the tissue to be stapled between the anvil and the lower surface of the cartridge and drives the staple by pressure on the finger grips closing the forceps and driving the staple from the cartridge.
  • the spring 134 causes the driver to return to the position illustrated in FIGURES 21 and 23 when the surgeon releases the pressure on the finger grips, and a new staple is advanced within the cartridge by the staple pusher as described above.
  • a stapler for use in fastening at each actuation a single miniature staple having two legs and a crown connecting said legs comprising in combination: (a) a pair of forceps including two arms movable' relative to each other; (b) a cartridge holder mounted between said arms on said forceps; (c) a cartridge removable and emplaceablo in a predetermined position on said holder, said cartridge having at its forward end opposing straight parallel shoulders perpendicular to the longitudinal axis of said holder and said cartridge containing a plurality of miniature staples each having two legs and a connecting crown, said staples being in parallel alignment within a centrally-located channel extending from one end of said cartridge to said parallel shoulders; the first of said staples being in contact with said shoulders and suspended between the walls of said channel; the crowns of all other staples being in frictional contact with the top surface of said channel and the free ends of each staple pointing in a direction perpendicular to the longitudinal axis of said cartridge; (d) a staple pusher s
