The effective tying of surgical knots is a critical skill for surgeons since if the knot does not stay intact, the consequences may be serious such as after pulmonary resection, laparoscopic cholecystectomy, and hysterectomy. The primary goal of surgical knot tying is to allow the capacity of a knot (or ligature) to be tightened and remain tight.
Negus' ligature slipper/knot tier: used with Negus's or Wilson's artery forceps to help tie sutures; help to slip the ligature over the tip of Negus or Wilson forceps during ligation of vessels following tonsillectomy. Negus' artery forceps: as a haemostat; replace tonsil artery forceps; ligature will not slip due to curve tip.
The surgeon's knot is a surgical knot and is a simple modification to the reef knot. It adds an extra twist when tying the first throw, forming a double overhand knot. The additional turn provides more friction and can reduce loosening while the second half of the knot is tied. [1] This knot is commonly used by surgeons in situations where it ...

Tying the knot coil knot. The double overhand knot [1] or barrel knot [2] [3] is simply an extension of the regular overhand knot, made with one additional pass. The result is slightly larger and more difficult to untie. It forms the first part of the surgeon's knot and both sides of a double fisherman's knot.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread .
Surgical mesh is a medical implant made of loosely woven mesh, which is used in surgery as either a permanent or temporary structural support for organs and other tissues. Surgical mesh can be made from both inorganic and biological materials and is used in a variety of surgeries, although hernia repair is the most common application.
The harmonic scalpel may be superior to electrosurgery in that it can cut through thicker tissue, creates less toxic surgical smoke, and poses somewhat less of a risk for electrocution or other potentially fatal complications. [1]
