1. Simulator for teaching surgical knot tying techniques comprising:
- flexible tube means adapted to be encircled by a tightenable surgical loop;
a plurality of conductive means within said tube means;
signal means for indicating when manipulation of the loop has caused at least two of said conductive means to come into contact.

Abstract
A simulator for and a process of teaching surgical knot tying techniques. A flexible tube made of material which simulates various human vessels and ducts is positioned between the arms of a support frame. Inside the tube are spring wires, which are strung under tension between the arms of the support frame. A detecting device is connected to the wires, which will generate various kinds of signals when the wires make contact with one another. The student loops a piece of surgical thread around the tube and tightens the loop until wires touch, thus indicating that a certain force has been applied to the tube by the loop.

10. Process of teaching surgical knot tying techniques which comprise:
-
(a) forming a loop of surgical thread around a flexible tube having diametrically spaced conductors therein; (b) loosely forming a surgical knot with the thread; (c) pulling on the thread until two conductors are brought into contact with each other, generating a signal indicative of the contacting of the conductors; (d) pulling downwardly on the other end of said thread until a signal is generated in said detecting means; (e) inserting a tension adjusting means in one end of said tube; repeating steps a through d above.
