Intended Use

The SurgASSIST™ Straight Linear Stapler and Straight Linear 4 Row No Knife Digital Loading Units® with Reloads have applications for general and endoscopic surgery in gastrointestinal, gynecological, general abdominal and thoracic surgical procedures for resection, transection, and creation of anastomoses.

Device Story

SurgASSIST™ Straight Linear Stapler and 4-Row No-Knife Digital Loading Units (DLUs) are single-patient-use surgical staplers. The device consists of a DLU attached to a flexible shaft (FlexShaft) connected to a Power Console (PC). The surgeon operates the device via a handheld electronic Remote Control Unit (RCU). The DLU features an anvil and staple cartridge that compresses tissue, forms staples, and (in stapler models) cuts tissue. The device is used in general and endoscopic surgery to secure tissue layers. Each DLU/Reload contains an electronic memory module that identifies the component type and prevents reuse of fired cartridges. The system provides mechanical power for stapling and cutting, allowing the surgeon to adjust the DLU attitude for optimal access. The output is a stapled (and optionally cut) tissue line, facilitating resection and anastomosis.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: Titanium staples. Energy: Mechanical power via Power Console. Connectivity: Electronic memory module in DLU for identification and reuse prevention. Sterilization: Ethylene Oxide (ETO). Form factor: 15mm diameter DLU, axial to FlexShaft. Software: Embedded firmware for DLU identification and lockout.

Indications for Use

Indicated for general and endoscopic surgery in gastrointestinal, gynecological, general abdominal, and thoracic procedures requiring resection, transection, and creation of anastomoses. Contraindicated for tissue requiring excessive force to compress to specified heights (1.2mm-2.0mm) or tissue that compresses easily below these heights.

Regulatory Classification

Identification

Endopath ETS Flex45 No-Knife Articulating Linear Stapler, Ethicon Endo-Surgery, Inc., Cincinnati, OH. REF NAB, NAG. (K020779). - 4) Device Description: The devices described here are reloadable Straight Linear Stapler and Straight Linear 4 Row No Knife Digital Loading Units® (DLUs) with Reloads for single patient use. All have a maximum diameter of .596" and can be used within a 15 mm cannula. The DLUs are supplied pre-sterilized and ready for use upon removal from their packaging. Reloadable stapling and cutting cartridges are referred to as "Reloads". Each DLU contains a staple-forming anvil. The anvil acts with the staple cartridge to compress and position layers of tissue in readiness for stapling and cutting. At the same time, the anvil provides support and a means for correctly forming staples while they are closed sequentially along the tissue, followed by the cutting blade, when included. The 15 mm diameter DLUs are axial to the FlexShaft, forming a straight extension to the FlexShaft, to which they are connected. Loaded Straight Linear Stapler and Straight Linear 4 Row No Knife DLUs are used to close otomies and other common and uncommon openings by applying staples through the tissue and forming the staples to a controlled closed condition to secure the layers of tissue together. Straight Linear Stapler and Straight Linear 4 Row No Knife Reloads contain staples and the means to sequentially force staples toward the anvil. The cutting blade, when included, is advanced immediately behind the staple pushers so that tissue is sequentially stapled and then cut, proceeding from one end of the cartridge to the other. Straight Linear Stapler DLUs, 55 mm with Blue and Green Reloads have 2 staggered rows of staples on one side of the cutter, coded Blue (1.2 mm) for normal tissue and Green (2.0 mm) for thick tissue. DLUs are available with Blue or Green Reloads installed. Individual Blue and Green Reloads are available. Straight Linear 4 Row No Knife DLUs, 55 mm with Gray Reloads have two, double-staggered rows of staples, coded Gray (1.2 mm) for normal tissue (same as 55 mm Blue Straight Linear Cutter without the blade). DLUs are available with Gray cartridges installed. "No Knife" distinctively labeled. Individual Gray Reloads are available. The DLUs are attached to the end of the flexible shaft assembly that contains a pair of flexible rotary drive shafts within an overall flexible tube called the FlexShaft, hereafter referred to as FS. The other end of the FS is connected to a Power Console (PC), which applies mechanical power to the drive shafts. {2}------------------------------------------------ DLUs have all functions powered by the PC. The FS has a short steerable section at the distal end (near the attached DLU) so that the angle of attack (attitude) of the DLU can be adjusted by the surgeon to optimize patient accessibility. The surgeon operates a DLU via a hand held electronic Remote Control Unit (RCU) that is plugged into the front panel of the PC. The DLUs have quick attach and release means of coupling to the FS. No tools are required. DLUs are pushed onto the FS end, snapping and locking into place. To remove a DLU from the FS, a sleeve on the DLU at the junction with the FS, is rotated by hand. DLU designs allow for attachment of Reloads, but will inhibit attachment of incompatible Reloads. Each Reload has an integral electronic memory module. This identifies the type and size of the Reload being used and prevents a used Reload from being refired. - 5) Indications For Use The SuraASSIST™ Straight Linear Stapler and Straight Linear 4 Row No Knife Digital Loading Units® with Reloads have applications for general and endoscopic surgery in gastrointestinal, gynecological, general abdominal and thoracic surgical procedures for resection, transection, and creation of anastomoses. - 6) Comparison to Predicate Devices The following table compares the subject Straight Linear Stapler and Straight Linear 4 Row No Knife Digital Loading Units® with Reloads to the previously cleared predicate Straight Linear Cutter Digital Loading Units® with Reloads (K020719). {3}------------------------------------------------ Pow.
