【Scope of application】

Disposable minimally invasive fascial closer are used to gather tissue and perform percutaneous sutures to close surgical incisions during laparoscopic surgery.

【Product performance】

1. Pull the push handle backward along the closing firmware handle. The sliding should be flexible and there should be no obvious looseness.

2. When the push handle reciprocates in a straight line along the closing firmware handle, the cable frame opens and closes freely without any jamming.

3. When the thread puller is in the open state, insert the grabber along the needle hole. The thread hook of the grabber should be able to hook the suture smoothly without any thread drop.

4. The button spring should have good elasticity, and there should be no jamming when the button is reset after being locked.

【Main structural components】

The disposable minimally invasive fascial closer consists of two parts: a closing firmware and a grabber. The closing firmware is mainly composed of a clamping block, a wire frame, a closing firmware handle, and a push handle; the grabber is mainly composed of a button, a button spring, and a grabber. It is composed of a handle, a puncture needle and a hook with thread. This product is supplied in a sterile condition, sterilized with ethylene oxide, and is intended for single use.

【Instructions】

1. Removing the Instrument: First, inspect the packaging for damage (do not use if the packaging is damaged). Then, tear open the packaging and remove the closure hardware and grasper.

2. Preloading Sutures: Pass the sutures through the thread guide, clamping block, and thread guide around the closure hardware, leaving ample thread length (Figure 1). (Sutures are not included with this product, but must be used with 2-0 or 0 sutures.)

3. Installing the Closure Hardware: First, insert the closure hardware through the incision. Then, press the push handles on both sides of the closure hardware, pull upward and lock to expand the thread guide. Unfold the sutures and pull the closure hardware upward to ensure the guide is flush against the abdominal wall (Figure 2).

4. Removing Sutures: Insert the grasper through the needle hole of the closure hardware until it stops. Press the grasper button and lock it. Pull back on the grasper needle to remove the suture. Repeat the same process to remove the suture on the other side (Figure 3). 5. Remove the closure: Press and hold the push handles on both sides of the closure, push downward, and lock to close the suture holder. Then, lift the closure outward along the incision, remove the closure, and leave the suture in place (Figure 4)(Figure 5).

5. Suture the incision: Tighten the sutures with the suture tips, tie a knot, and suture the fascia of the incision (Figure 6).
