Operation Techniques

Step-by-Step Use

Using a Surgical Knot Pusher in laparoscopic surgery requires careful attention to detail. The following steps outline a recommended approach for safe and effective knot tying^[2]:

1. Select the right instrument length for the surgical site. Most laparoscopic procedures use a tool between 33 and 45 centimeters.

2. Check that the tip design matches the suture material. Braided and monofilament sutures may need different tip shapes.

3. Make sure the surgical field is visible. Use the endoscope to see the suture ends clearly.

4. Form the first knot. Beginners often start with an extracorporeal knot, which is tied outside the body.

5. Thread one end of the suture through the knot pusher. The knot should rest against the tip.

6. Hold the other suture end with steady tension. This helps control the knot as you advance it.

7. Slide the knot pusher gently down the suture toward the tissue. Use smooth, even pressure.

8. Watch the knot as it moves. Adjust your speed if you feel resistance or see the knot behave differently.

9. Seat the knot firmly against the tissue. Press just enough to secure it without causing damage.

10. Repeat these steps for each additional throw. Most procedures require at least four or five throws for a secure knot.

Tip: Practice these steps with different suture materials to build confidence and skill.

Safety Tips

• Always inspect the instrument before use. Look for cracks or damage.

• Use a new, sterile knot pusher for each patient to reduce infection risk.
