The Laschal Precision Suture Tome (PST):

Based upon the concept that a surgical knot is thicker than a single strand of suture, the PST outperforms all other scissors for precise clipping of sutures. When surgeons or assistants attempt to clip sutures at the correct level above the knot, they face two inherent problems: How to avoid cutting tissue as they attempt to locate the knot and, once located, how to guarantee the precise cutting of the suture so it's not too long (interfering with surrounding tissue) or too short (encouraging unraveling). A difficult situation at best, when retraction or visibility is not maximal.

A simple slot solves both problems One model PST (the 403) is reversible. Used one way, it leaves the perfect 2mm tag. Reversed, it slides the blade all the way down to the knot itself, where the assistant cuts the suture exactly flush with the knot. This model is already well known by plastic and ENT surgeons. Each slot size is compatible with 5 continuous suture sizes, and is marked on each instrument. The PST is a unique assistant's instrument that completely eliminates the dangers of cutting tissue as it assures that the suture is cut at the desired level above the knot.
Here's how it works:
1. Once the surgeon makes the tie, the assistant takes the PST and guides the suture easily into a special slot on the blade.
2. The assistant slides the PST down the suture, which guides it directly to the knot, gently nudging aside any tissue as it descends.
3. The knot, which is thicker than the slot is wide, stops the Laschal PST.
4. The offset blade is set to be approximately 2mm above the knot.
5. The assistant then cuts the suture with precision and ease. Assistants can virtually perform this precise function blindfolded, as they often must do when visibility is poor. Anesthesia time is saved and blood loss is reduced.

Ideal for(absorbable) interrupted subcuticular sutures One model PST (the 403) is reversible. Used one way, it leaves the perfect 2mm tag. Reversed, it slides the blade all the way down to the knot itself, where the assistant cuts the suture exactly flush with the knot. This model is already well known by plastic and ENT surgeons. Each slot size is compatible with 5 continuous suture sizes, and is marked on each instrument.

The special slot in the PST uses the suture as a guide...

descending to the knot as it gently pushes tissue aside...

....stopping approximately 2 mm above the knot, so the surgeon or assistant can cut the suture precisely and neatly.

PROPER MAINTENANCE OF THE LASCHAL INSTRUMENTS:
Immediately following use, the instrument should be soaked and scrubbed prior to sterilization.
Upon completion of sterilization a drop of bacteriostatic surgical milk should be applied to the articulate.
