KOCHER RETRACTOR 4 PRONGS BLUNT 22,0CM

KOCHER RETRACTOR • 4 BLUNT PRONGS • 22.0 CM • CE CLASS I • ISO 13485:2016

Atraumatic Wide-Area Retractor for Maximum Tissue Preservation Under Stable Retraction

The KOCHER Retractor with 4 blunt prongs, 22.0 cm is a Class I medical device according to ISO 13485:2016. This specialized instrument was developed to enable the demanding combination of broad-area, powerful retraction and absolutely atraumatic tissue handling. With four fully blunt prongs, it is the instrument of choice for the exposure and holding of extensive soft tissue areas in highly sensitive surgical fields.

Advantages of the KOCHER Retractor (4 blunt prongs):

• Maximum Surface Adhesion with Zero Trauma Risk: Four blunt prongs create an exceptionally large contact area, enabling secure retraction while simultaneously eliminating any risk of puncture, cut, or perforation injuries.
• Optimal Pressure Distribution: Retraction pressure is evenly distributed across a large tissue area, effectively preventing pressure necrosis, hematoma formation, and tissue crushing.
• Perfect for Vulnerable Structures: Designed for work in immediate proximity to bowel, major vascular trunks, spleen, liver, and other parenchymal organs.
• Stable Exposure: Enables the safe holding open and presentation of extensive surgical fields (e.g., the entire upper abdomen or the pelvic cavity) over extended periods.
• Biologically Oriented Surgery: Supports the principles of gentle surgery and can thus contribute to reduced postoperative adhesions and improved healing.

Fields of Application:

• Hepatobiliary and pancreatic surgery (liver resections, Whipple procedure)
• Colorectal surgery with total mesorectal excision (TME)
• Major urological and gynecological tumor surgery
• Transplant surgery (liver, kidney transplantation)
• Revision surgery for extensive intra-abdominal adhesions

Important Application Notes:

• FOR USE BY EXPERIENCED SURGICAL PERSONNEL ONLY.
• Atraumatic high-performance instrument. Nevertheless requires a sensitive feel for measured pressure to prevent pressure damage.
• Before each use, subject all four prongs to a thorough visual inspection for absolute smoothness, roundness, and structural integrity.
• Not suitable for dissecting or mobilizing tissue. Designed purely for retraction and presentation.
• Enables the safest form of retraction in the most critical anatomical regions but is not designed for extremely dense or scarred tissue.
• During reprocessing, ensure meticulous cleaning between prongs.
• Discard immediately in case of any damage, bending, or wear of the polished prong surface.
