Definitions

  • the present disclosure relates to energy-based surgical instruments and, more particularly, to energy-based surgical forceps configured for treating and/or cutting tissue.
  • a forceps or hemostat is a plier-like instrument which relies on mechanical action between its jaws to grasp, clamp, and constrict tissue.
  • Energy-based forceps utilize both mechanical clamping action and energy, e.g., electrosurgical energy, ultrasonic energy, light energy, microwave energy, heat, etc., to affect hemostasis by heating tissue to coagulate and/or cauterize tissue.
  • Certain surgical procedures require more than simply cauterizing tissue and rely on the unique combination of clamping pressure, precise energy control, and gap distance (i.e., distance between opposing jaws when closed about tissue) to “seal” tissue.
  • the surgeon has to accurately sever the tissue along the newly formed tissue seal.
  • many tissue sealing instruments have been designed to incorporate a blade that is movable with respect to a blade slot disposed in a jaw of the tissue sealing instrument to sever the tissue after forming a tissue seal.
  • the proximal portions of the first and second jaw members extend along the longitudinal axis and the distal portions are longitudinally and laterally twisted with respect to the longitudinal axis.
  • the first and second tissue contacting surfaces define a triangular-shaped gap therebetween when in the first approximated position.
  • the electrosurgical instrument may further include first and second handle members disposed at proximal end portions of the first and second shaft members.
  • the first handle member includes a raised rail and the second handle member includes a bump stopper.
  • the electrosurgical instrument further includes a connector assembly releasably engaged with the raised rail of the first handle member.
  • the bump stopper engages a switch disposed in the connector assembly when the first and second shaft members are in the first approximated position to automatically activate a source of electrosurgical energy.
  • FIG. 2 is a side, perspective view of the forceps of FIG. 1 with parts separated;
  • FIG. 5C is a cross-sectional view of jaw members of the forceps of FIG. 5A, taken along line 5C-5C of FIG. 5A, and including tissue disposed between the jaw members;
  • the forceps 100 includes a first elongated shaft member 110 pivotably coupled to a second elongated shaft member 120.
  • the first elongated shaft member 110 includes proximal and distal end portions 112 and 114, respectively, and the second elongated shaft member 120 includes proximal and distal end portions 122 and 124, respectively.
  • the proximal end portions 112 and 122 of the first and second shaft members 110 and 120 include first and second handle members 130 and 140, respectively.
  • the first and second handle members 130 and 140 are configured to allow an operator to effect movement of one or both of the first and second shaft members 110 and 120 relative to the other.
  • the distal end portions 114 and 124 of the first and second shaft members 110 and 120 cooperate to define an end effector assembly 115 having opposed first and second jaw members 150 and 160.
  • first and second shaft members 110 and 120 intersect at intersection portions 116 and 126, respectively.
  • the intersection portions 116 and 126 of the first and second shaft members 110 and 120 define openings 116a and 126a, respectively, therethrough, for receiving a pivot pin assembly 170 for coupling the first and second shaft member 110 and 120 together.
  • the pivot pin assembly 170 includes a spring pin 172, an insulated washer 174, and a pin head 176.
  • the spring pin 172 includes a body portion 172a including a flange 172b at a first end thereof and a tail portion 172c, which has a smaller diameter than the body portion 172a, extending from a second end of the body portion 172a.
  • the flange 172b is positioned against the insulated washer 174, which is positioned within a recess defined in an outer surface of the second shaft member 120 (FIG. 5B) .
  • the insulative washer 174 can be replaced by an insulative coating on the second shaft member 120.
  • first and second jaw members 150 and 160 When this lateral movement between the first and second jaw members 150 and 160 is larger than the width of the first and second jaw members 150 and 160, the shear-edge configured side edges 154 and 164 of the first and second jaws 150 and 160 cut the tissue “T” bound between the first and second jaw members 150 and 160, and the boundary tissue disposed within the gap “G J ” defined between the proximal portions 150a and 160a of the first and second jaw members 150 and 160 is not cut.
  • the first and second handle members 130 and 140 may then be returned to the open position. As shown in FIGS. 7A-7C, in the example method described above, a vessel “V” may be sealed “S” and cut “C” without affecting the tissue “T” surrounding the vessel “V” .
  • Distal portions 150b' and 160b' include first and second tissue contacting surfaces 152' and 162' that define side edges 154' , 164' , wherein at least one side edge 154' , 164' of each of the first and second tissue contacting surfaces 152' and 162' defines a shear-edge configuration, e.g., the convex side edge 154' of first tissue contacting surface 152' of first jaw member 150' and the concave side edge 164' of second tissue contacting surface 162' of second jaw member 160' .

Abstract

L'invention concerne un instrument électrochirurgical (1) qui comprend un effecteur terminal (115) comportant un premier et un second élément mâchoire (150, 160) placés autour d'un axe longitudinal (z). Les premier et second éléments mâchoires (150, 160) comprennent des parties proximales (150a, 160a) délimitant un espace (G J) entre celles-ci, et des parties distales (150b, 160b) comportant une première et une seconde surface (152, 162) en contact avec le tissu, respectivement, et des bords de cisaillement sur des côtés opposés (154, 164) des première et seconde surfaces (152, 162) en contact avec le tissu. L'effecteur terminal (115) est conçu pour transmettre sélectivement de l'énergie électrochirurgicale entre les première et seconde surfaces (152, 162) des premier et second éléments mâchoires (150, 160) lorsqu'il est actionné. Le premier et/ou le second élément mâchoire (150, 160) est/sont mobile(s) par rapport à l'autre élément entre une position ouverte, une première position rapprochée dans laquelle les première et seconde surfaces (152, 162) en contact avec le tissu sont sensiblement opposées l'une à l'autre, et une seconde position rapprochée dans laquelle les première et seconde surfaces (152, 162) en contact avec le tissu sont décalées latéralement l'une par rapport à l'autre.
