Olympus Medical Systems Corporation (President Haruhito Morishima) has announced the introduction of a variety of new medical devices specifically designed for Laparo-Endoscopic Single-Site surgery (LESS surgery). LESS surgery is an advanced, minimally invasive surgical technique in which an endoscope and hand instruments are inserted through an access port via a single incision, such as a transumbilical incision. Release of these devices is scheduled for October, 2009 in Europe, North America, and parts of Asia.

Three kinds of devices will be released: the QuadPortTM disposable multi-instrument access port, which can simultaneously accommodate up to four instruments including an endoscope through a single incision; the HiQ LS curved 5-mm diameter hand instruments, which feature a shaft with curved distal and proximal ends to prevent interference with other devices; and the EndoEYE LS Laparo-Thoraco Videoscope, which incorporates a deflectable control section to prevent interference with other devices.

Market Introduction Background

While traditional laparoscopic surgery offers benefits like less pain, faster recovery time, and improved cosmesis over open surgery, LESS surgery has the potential to extend these benefits even further because it offers surgeons the ability to perform procedures through only one small incision in the bellybutton. LESS surgery may not be appropriate for all patients, and there is still much to be learned about this emerging technology. Olympus has played a leading role in supporting the growth of this market by offering a wide variety of products designed for laparoscopic surgery, including endoscopes, ancillary equipment, and therapeutic devices. In recent years, incision sizes have been further reduced thanks to reductions in the diameters of the trocars inserted in several incisions in the abdomen and in the instruments passed through them. LESS surgery, which is intended to require only a single incision, is now frequently performed in clinical cases in some countries. By commercializing devices compatible with LESS surgery, Olympus will continue to fulfill its commitment to helping reduce stress on patients and improve their quality of life. In addition to its contribution to the development of laparoscopic surgery, Olympus remains committed to the advancement of minimally invasive surgery - including experimental techniques such as NOTESTM* - by integrating product development technologies for gastrointestinal endoscopy, endoscopic treatment, and endoscopic surgery.

* Stands for Natural Orifice Translumenal Endoscopic SurgeryTM. A new type of endoscopic intervention procedure in which a flexible endoscope is introduced to the abdominal cavity passed through a natural orifice (mouth, urethra, anus, etc.) then through an internal incision in a luminal organ such as the stomach, colon, uterus, or bladder, thus avoiding any external incisions or scars. Research is now actively underway on a global scale.

Main Product Features

QuadPortTM Disposable Multi-Instrument Access Port

  1. Flexible sleeve design is compatible with various incision sizes and abdominal wall thicknesses, while facilitating insertion of devices like pre-curved hand instruments to help improve maneuverability.
  2. Four ports - one φ15-mm, two φ10-mm, and one φ5-mm - are provided to enable selective insertion of an endoscope and forceps according to their diameters.
  3. Insufflation/venting ports used for feeding CO2 gas and evacuating smoke from electrocautery and laser procedures are integrated to ensure the operating field remains clear.
  4. A specimen can be easily removed by withdrawing the specimen into the distal end of the QuadPortTM and removing the port.

HiQ LS Curved φ5-mm Hand Instruments

  1. ncorporating a rigid curved shaft with angulated distal end and proximal end, these instruments can be introduced to the site from an oblique angle, allowing more intuitive maneuvering. This design decreases interference between instruments inside the body cavity even when two are simultaneously inserted into the trocar.
  2. Because the distal end can be rotated by turning the rotation knob on the control section side of the shaft, the entire instrument does not have to be rotated, decreasing interference with an endoscope and other instruments inside the body cavity.
  3. This is a reusable product.

EndoEYE LS Laparo-Thoraco Videoscope with a CCD Built into the Distal End

  1. The control section is contoured in straight lines thanks to the integration of the light guide cable, ensuring a roomy workspace by preventing interference with other devices outside the body cavity.
  2. The control section can be bent by as much as 90 degrees, also helping decrease interference with other devices outside the body cavity.
  3. The incorporation of a CCD in the distal end causes the scope tip to heat up, which prevents fogging to ensure clear field of view. An excellent depth of field and advanced autofocus are also provided.

Reference Material

The following instruments that can be used for LESS surgery from Olympus are already available.

  1. LTF TYPE VP VISERA Laparo-Thoraco Videoscope (currently on sale worldwide)
    Measuring 5.4 mm in outer diameter, this deflectable-tip laparo-thoraco videoscope features a distal end that can be angulated in four directions. Together with the deflectable-tip design, this allows surgeons to view the interior of the body cavity from multiple directions. The incorporation of a high-performance CCD in the distal end delivers bright, clear images in spite of the narrow diameter.
  2. LTF TYPE VP VISERA Laparo-Thoraco Videoscope

  3. TriPortTM Disposable Multi-Instrument Access Port (currently on sale in Europe, North America, and parts of Asia
    Simultaneously accommodating up to 3 instruments including an endoscope via a single incision, this disposable multi-instrument port is provided with 3 ports, two φ5-mm and one φ12-mm, to enable selective insertion according to the outer diameters of the endoscope and hand instruments.
