Definitions

  • This invention relates to a method and apparatus for use in laparoscopic and endoscopic surgery. More particularly, this invention relates to a surgical instrument which may be used separately in conjunction with a laparoscope or endoscope or as an integral part of a laparoscope or endo ⁇ scope. This invention also relates to a method for performing surgery using such an instrument. Background of the Invention
  • Laparoscopy involves the piercing of the abdominal wall and the insertion of a tubular port member through the perforation.
  • Various instruments may be inserted through the tubular member to perform surgical operations inside the abdomen.
  • the abdominal cavity is pressurized to distend the abdominal wall and pro ⁇ vide a safety region between the wall and the body organs inside the cavity.
  • several perforations are made.
  • One perforation receives a laparoscope which enables visual monitoring of organs and surgical activities inside the abdominal cavity.
  • Other perforations serve for the insertion of different surgical instruments.
  • Laparatomic surgery provides several advantages over conventional incision-based surgery.
  • the laparotomic perfora ⁇ tions in being substantially smaller than the incisions made during conventional operations, are less traumatic to the patient and provide for an accelerated recovery and convales ⁇ cence. Hospital stays are minimized.
  • laparo ⁇ scopic surgery is less time consuming and less expensive than conventional surgery for correcting the same problems.
  • laparatomic surgery is performed with rigid instruments, the distal end portions of which are inserted into the patient's abdominal cavity through one or more tubular port members inserted in perforations formed in the abdominal wall.
  • the tubular port members are tilted or pivoted.
  • the distal terminal portions of some laparoscopes are flexible and bendable under control of the surgeon by the manipulation of actuator members outside the patient.
  • surgical instruments such as biopsy forceps, graspers, trocars, suction devices, irrigators, scissors, cautery devices, staplers, suture applicators and clamps, may be inserted through one or more longitudinal channels in the laparoscopes or endoscopes.
  • These instruments are at least partially flexible to enable them to flex with the bending type motions of the laparoscopes or endoscopes in which they are inserted.
  • An object of the present invention is to provide a method and an associated apparatus for facilitating access to internal body tissues of a patient in laparoscopic or endo ⁇ scopic operations.
  • Another, more particular, object of the present invention is to provide such a method and apparatus which facilitates the performance of surgical operations on internal body tissues which are located on sides of organs away from a laparoscope or endoscope.
  • a further particular object of the present invention is to provide such an instrument assembly which is easy to use.
  • An instrument assembly for use in laparoscopic or endoscopic surgery comprises, in accordance with the present invention, a laparoscope or endoscope and a surgical or operating instrument.
  • the laparoscope or endoscope includes a tubular member for insertion into a patient's body, the -tubular member being flexible at least in a region about a distal end thereof.
  • the tubular member includes an elongate channel extending longitudinally therethrough, the channel having a characteristic diameter.
  • a control element is pro ⁇ vided on the laparoscope or endoscope for control-ling a bend ⁇ ing type motion of the tubular member in the flexible region at the distal end of the instrument.
  • the surgical instrument has an elongate body portion with a diameter smaller than the characteristic diameter of the laparoscope or endoscope chan ⁇ nel, whereby the surgical instrument is insertable into the channel.
  • the elongate body portion of the surgical instrument is flexible at least in an area about a distal end of the instrument.
  • An actuator is provided on the surgical instru ⁇ ment for controlling a bending type motion of the elongate body portion of the instrument in the flexible area at the distal tip of the instrument.
  • the actuator is operable inde ⁇ pendently of the bending control element for the laparoscope or endoscope.
  • the surgical instrument has an operative component on the elongate body portion at a distal end thereof for implementing a surgical type operation on internal body tis ⁇ sues of the patient.
  • the operative component may take the form of a scissors, a grasping forceps, a biopsy forceps, a clamp, a stapler, a suture applicator, an irrigation or suc ⁇ tion port, a scissors, a cautery device or any other device for performing surgical type operations on internal body tis ⁇ sues.
  • the surgical instrument also has an actuator element on the elongate body portion which is coupled to the operative component for enabling a surgeon to use the operative com ⁇ ponent for performing the respective surgical operation.
  • the actuator for the bending type motion of the surgical instru ⁇ ment is operable separately from the actuator for the opera ⁇ tive component.
  • the present invention is therefore directed in part to a surgical instrument for use in conjunction with a rigid or partially flexible laparoscope or an endoscope.
  • the surgical instrument comprises an elongate body portion which is flexible at least in an area about a distal end of the elongate body portion of the surgical instrument.
  • the surgical instrument also comprises an opera- tive component on the elongate body portion at the distal end thereof for implementing a surgical type operation on internal body tissues of the patient.
  • a first actuator is provided on the elongate body portion of the surgical instrument and is operatively connected to the operative component for enabling a surgeon to use the operative component for performing the surgical type operation.
  • a second actuator is provided on the surgical instrument for controlling a bending type motion of the elongate body portion in the flexible area about the dis ⁇ tal end of the surgical instrument.
  • This bending is imple ⁇ mented independently of any bending motion of the laparoscope or endoscope.
  • the actuator for bending the surgical instrument's distal end portion is operable separately from the actuator for working the operative component (forceps, clamp, stapler, etc.).
  • the diameter of the elongate body portion of the surgi ⁇ cal instrument is smaller than a characteristic diameter of the laparoscopic or endoscopic biopsy channel, so that the surgical instrument is insertable into that channel.
