It is of note that in FIG. The fully engaged plunger 145 and cam button 135 continue to move distally within the handle body assembly 40 to the positions of FIGS. 5 is a section view of a portion of the left handle cover in crosshatch and a portion of the right handle cover in phantom lines; FIG. The surgical instrument 30 of the preferred invention is shown in FIGS. Assignors: KOCH, JR., ROBERT L., MEASAMER, JOHN P., NGUYEN, ANTHONY T., WELCH, ROBERT F. Surgical instruments, devices or methods, e.g. 5,314,424, and Measamer et al. The cam button 135 has a central button shaped disk 136, a proximal post 137 that attaches to the flexible member 130, and a distal guide shaft 138. So, to release the strap from the ratchet, you must ensure you apply pressure on the manual pawl. Another first at Felo: combining the functionality of a ratchet and swivelling screwdriver with the comfort of the ERGONIC handle. No. Actuation member 105 is releasably locked and unlocked by a release trigger 120 of a releasable locking mechanism 115 (FIGS. The end effectors are operably coupled to the actuation handle by the shaft. 3 is an isometric view showing all of the components of FIG. Significantly, the novel hand held surgical instrument for grasping and clamping tissue provides the surgeon with a releasable locking mechanism that is intuitive to use. Saved by Raymond Tracy. 1 showing the subassemblies that mount within a handle body assembly of the handheld surgical instrument; FIG. A small sectioned portion of the locking peak 63 of the right handle cover 45 is shown in cross hatch in FIG. 1 with the right cover removed to show the position of the elements when the releasable locking mechanism is unlocked; FIG. Movement of the actuation member 105 moves the actuation rod 83 proximally and distally within the elongated shaft assembly 80, and opens and closes the first and second jaw members 96 and 97.

In a typical laparoscopic surgery, the abdominal cavity is insulated with an inert gas and surgical access ports are inserted into the patient. 4) from the locking peak 63 to intersect with the vertical surface 60 (of vertical slot 59) at a locking edge 61. First and second jaw members 96 and 97 are opened by unlocking the releasable locking mechanism 115 with a second reciprocation of the release trigger 120. He likes doing long distance overland travel and would happily spend every night in the bed of a pickup under the stars. the release mechanism is activated to allow the pawl to be pushed back into the sleeve and the harness to raise. The flexible member 130 is a tightly coiled spring that transmits force and motion inputs from the release trigger 120 to the other moving elements of the releasable locking mechanism 115 in an arcuate path. While preferred embodiments of the present invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. 1 shows an isometric view of the surgical instrument 30 of the preferred invention. 2 23 0. In many ratchet mechanisms the pawl is held against the wheel during motion by the action of a spring. Occasionally, the pawls will stick which makes it hard to tighten or loosen the strap. Opening the closed actuation member 105 is now impossible without an additional reciprocation of the release trigger 120 to disengage the releasable locking mechanism 115. When it's partially open both pawls are mostly engaged. As shown in FIG. It can be hard to make the ratchet strap tight, so your load won't be secure. If you have a choice between the two types of ratchet straps, the outside release is much safer to use because it keeps your fingers away from the inside of a ratchet strap under tension. 5. The release trigger is moveable from a first position spaced away from the handle body to a second position adjacent to the handle body. 6 the locking tab 155 is pivotably mounted within the locking tab slot 69 within the left handle cover and is shown in the unlocked position. 8. At this point both the trigger spring 125 and the locking tab spring 165 are fully compressed. Laparoscopic grasping instruments having a pair of scissors-like handles and an easily accessible trigger for unlocking the pawl from the ratchet were disclosed by Green et al. The assembled actuation ball halves 90 form a ball shaped rotation and actuation coupling that mounts within a ball socket 109 that is located inside a left member half 110 and a right member half 111 of the actuation member 105. 1 with the right cover removed to show the elements when the releasable locking mechanism is locked; FIG. In partially folded positions, the handle gets out of the way for greater access. 4) and the unlocking ramps 65 (FIG. 10 and 11. The present invention relates, in general, to handheld surgical instruments and, more particularly, to a new and useful reciprocating releasable locking mechanism for locking and unlocking the actuation member of a laparoscopic hand held instrument. 7 is also provided to show a sectioned view of the plunger 145 and the plunger bore 67 to emphasize the capture of both of the plunger peaks 151 within both of the valleys formed by stop surfaces 66 and the unlocking ramps 65. Ratchet and Release Mechanism for Swing Arm of Table Saw . 3 is an exploded isometric view showing all of the elements of the handheld surgical instrument of FIG. Additional distal movement of the elements of the releasable locking mechanism 115 enable the distal plunger peaks 151 of the plunger 145 to move proximally past the unlocking edge s 64a of the vertical surfaces 60 (FIG. The locking tab 155 is oriented vertically within the handle body assembly 40 by the locking rod 108 passing through the locking hole 156. The image with a lot of pink is a ratchet strap with the right amount of strap. Once it's flat, you can let go of the little handle and just pull the ratchet towards you - it'll now be loose and ready to release. The elongated shaft assembly 80 mounts within the left handle cover with the placement of the handle flange 52 within the groove 82 of the elongated shaft assembly 80. Mechanism for locking and releasing an elongated socket or other fitting having a laterally extending side hole, comprising a generally cylindrical body, a non-annular stud extending from said body and being coaxial therewith, said body and said stud having an axially extending first bore therein, a rod slidable in said first bore, one end of said rod being oriented so as to be movable by a person's finger and the … The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure. The locking teeth 62 and the unlocking teeth 64 alternate around the plunger bore 67 as best shown in FIG. 35. 2, the distal end of the left handle cover 50 has a handle flange 52 extending inwardly and the elongated shaft assembly 80 has a groove 82 near the proximal end of the rotational knob 81. First you need to squeeze the little handle to disengage the manual pawl: This takes a bit of manual power to disengage; you will have to pull hard on the unhooked strap so that you can get the strap to finally uncoil from the spool. The backbone of the elongated shaft assembly 80 is an elongated shaft 85 formed from a thin sheet of surgical grade metal. Four equally spaced plunger teeth 153 of the same size and pitch as the four cam teeth 140 (FIG. Locking tab spring 165 constantly biases the pivoting locking tab 155 distally against the reciprocating plunger 145. 12. A cylindrical journal 68 is provided at a proximal end of the plunger bore 67 for the reception of the plunger 145.
