Intended Use

The Microline Flexible Ligating Shears are intended for simultaneous cutting and cauterization of soft tissue during minimally invasive abdominal laparoscopic surgery. The device may also be used for cutting natural, non-metallic sutures during surgery.

Device Story

Microline Flexible Ligating Shears are sterile, single-patient-use handpieces designed for thermal ligation and division of soft tissue. The device features distal heating elements activated by a finger switch on the handpiece. It connects to a Microline Universal Power Supply, which allows the surgeon to control heating power to accommodate patient anatomy. The device is used in conjunction with an introducer, such as the TransEnterix SPIDER Single Port Device, which provides flexible instrument delivery tubes (IDTs) to facilitate multidirectional, triangulated access to the surgical field. The system is operated by a trained physician in a minimally invasive abdominal laparoscopic setting. By conducting heat to tissue compressed within the jaws, the device enables simultaneous cutting and cauterization, potentially reducing the need for multiple instruments and improving surgical efficiency.

Clinical Evidence

Bench testing only. Functionality and ligating performance were verified. System compatibility with the SPIDER device was confirmed. Sterilization validated per ISO 11137-2 (SAL 10^-6). Biocompatibility testing performed per ISO 10993-1. Electrical safety testing performed per IEC 60601-1.

Technological Characteristics

Thermal ligation via distal heating elements; finger-switch activation; powered by external Universal Power Supply (max 60W). Sterile, single-use handpiece; non-sterile reusable power supply. Compatible with SPIDER Single Port Device. Sterilization: Gamma irradiation (ISO 11137-2). Biocompatibility: ISO 10993-1 compliant.

Indications for Use

Indicated for patients undergoing minimally invasive abdominal laparoscopic surgery requiring soft tissue cutting and cauterization or cutting of natural, non-metallic sutures.

Regulatory Classification

Identification

### Device Description and Technological Characteristics:

The Microline Flexible Ligating Shears system consists of the following:

Microline Flexible Ligating Shears Microline Universal Power Supply Single or multiple access port device such as the TransEnterix SPIDER Single Port.

The Microline Flexible Ligating Shears are designed to provide thermal ligation and division during minimally invasive abdominal laparoscopic surgery. The Microline Flexible Ligating Shears consist of a sterile single patient use handpiece. The device has heating elements at the distal tip which are activated by a finger switch located on the handpiece of the device. The Microline Universal Power Supply is designed to allow the surgeon control of the heating element power of the device in order to accommodate for individual patient anatomy. An instrument cord is attached to the handpiece and is plugged into the dedicated Microline Universal Power Supply.

The Microline Flexible Ligating Shears are designed to be used with an Introducer such as the SPIDER Single Port Device.

The shapes are enclosed within a circle, creating a pattern that looks like a stylized flower or a geometric emblem.

The logo on the right has a crown on top of a checkmark, and the text "UKAS Product Certification 026" is written below the checkmark. Both logos appear to be certification marks.

{1}------------------------------------------------

The Microline Flexible Ligating Shears are supplied sterile in a Tyvek/Mylar sterilization pouch on a mounting card and thermoformed tray, placed in a fiberboard carton. The device is intended to be used by a trained physician for a single patient use during minimally invasive abdominal laparoscopic surgery.

The Microline Flexible Ligating Shears power cable is attached to the instrument handpiece and connects to the Microline Universal Power Supply. The Universal Power Supply is supplied nonsterile for reusable use outside the sterile field.

The Microline Flexible Ligating Shears incorporates Hi and Low heating modes that are used to cauterize and cut soft tissue. The heating elements in the tip are activated by a physician controlled finger switch located on the handpiece of the device. The Microline Flexible Ligating Shears is intended to provide general purpose cauterization, spreading, and grasping of soft tissue during minimally invasive or open surgical procedures.

## Principle of Operation:

The Microline Flexible Ligating Shears provide a path of entry to the surgical target by the SPIDER device's flexible extended IDTs (Instrument Delivery Tube), also called the SPIDER Single Port Device. Two (2) flexible channels known as IDTs (Instrument Delivery Tubes) are positioned horizontally to the operative plane and include extended flexible lumens to facilitate manipulation of surgical instruments, enabling control over operator determined distances. The IDTs facilitate x, y, and z motion to allow for a multidirectional and triangulated approach within the surgical field. This mimics the approach of standard laparoscopic surgery using multiple incisions.

The flexible IDTs provide 360 degrees of freedom at the distal tips. The right hand controls the right instrument and the left hand controls the left instrument. Two (2) rigid channels positioned vertically to the operative field enable the use of an endoscope and any other surgical instruments.

## Indications for Use:

The Microline Flexible Ligating Shears are intended for simultaneous cutting and cauterization of soft tissue during minimally invasive abdominal laparoscopic surgery. The device may also be used for cutting natural, non-metallic sutures during surgery.

## Performance Testing:

The Microline Flexible Ligating Shears have been tested for functionality and they have found to perform their intended functions for minimally invasive abdominal laparoscopic procedures. Additionally, testing has proven that they perform their ligating functions. The device has also been tested with the SPIDER® device and pasted all required testing for system compatibility.

The Microline Thermal Ligating Shears have been sterilized to a SAL of 1x10* using gamma irradiation. The gamma sterilization process was validated to the following: - Clause 9, Method VDmax -Substantiation of 25 kGy or 15 kGy as the sterilization dose in ISO 11137-2. Sterile barrier testing has

been performed and it has been shown that the sterile barrier has the capability of maintaining sterility during the required shelf life, and that the device itself maintains its performance requirements.

Biocompatibility testing was successfully conducted on the Microline Flexible Ligating Shears in accordance with ANSI/AAMI/ISO 10993-1. The Microline Flexible Ligating Shears falls into the category of external communicating device and the appropriate tests were performed as described in Table A.1 in Annex A of ANSI/AAMI/ISO 10993-1.

The Microline Flexible Ligating Shears were evaluated by an independent testing laboratory and found compliant to IEC 60601-1:1988 + A1:1999 + A2:1995 general requirements for basic safety, including all US, CAN National Differences.

As illustrated in the Predicate Comparison Table below, the Microline Flexible Ligating Shears do not incorporate any significant technological differences that effect safety and efficacy. Therefore clinical data was not necessary for evaluation of substantial equivalence. The verification and validation test results are sufficient to demonstrate safety and effectiveness when compared to the predicate devices. The minor design or material differences between The Microline Thermal Ligating Shears and the predicate devices have been evaluated and tested and found to present no new issues of safety and effectiveness.
