Abstract

An apparatus used in simulating the human body cavity whereby an individual user can practice endoscopic surgical procedures by duplicating the operative steps performed on actual true to life condition for the purpose of learning the art and constantly improving the skill of eye-hand coordination and manual dexterity. The simulator is provided with open sides to gain access into the cavity for placement of objects simulating human organs which are then mounted and anchored inside the cavity for practice simulation in instrument manipulation. Surgical instruments are inserted into the cavity through the pre-established apertures on the transparent plastic panel and the instruments are manipulated while performing the practice procedure without the benefit of direct binocular vision on the object-simulations; instead the trainee imitates and directs the activities inside the cavity under vision using the endoscopic-video-monitor system or by similar indirect viewing method provided by the reflecting mirrors of the two mirror concept, thus mimicking a real life operative condition.

Claims

1. A surgical training apparatus which allows surgeons and trainees to learn and teach endoscopic surgery procedures by practice simulation of real-life conditions in order to improve skills in eye-hand coordination and manual dexterity comprising:

a) a box having a plurality of lateral sides, a top side, and a bottom side, and having a cavity therein, said cavity removably containing at least one of a plurality of unique objects simulative of human organs, said at least one of said plurality of objects allowing a particular endoscopic operative procedure to be performed;

b) access means in at least one of said plurality of lateral sides for allowing said at least one of a plurality of objects to be inserted into and removed from said cavity through said one of said plurality of sides;

c) means affixed to said box and within said cavity for mounting and fixedly anchoring said at least one of a plurality of objects adjacent said bottom side when said at least one of a plurality of objects is inserted within said cavity, said mounting and anchoring means comprising foam rubber;

d) one of a plurality of clear and transparent plastic panels slidably and removably affixed to said top side, each of said plurality of clear and transparent panels having a unique pattern of apertures located therethrough, each of said apertures being in receiving engagement with a rubber plate having an opening therethrough, said unique pattern of apertures permitting the practice of said particular operative procedure corresponding to the particular at least one of a plurality of unique objects which is concurrently held within said cavity, the concurrent use of said unique pattern and said at least one of a plurality of unique objects thereby permitting real-life simulation of said operative procedure; and

e) an adjustable pair of mirrors each having a reflective face, one mirror each attached to said box adjacent the top side, each said mirror being adjustably mounted such that each said mirror may be positioned in face-to-face relation to the other said mirror to provide an indirect way of viewing said at least one of a plurality of objects in the cavity during the practice procedure.

2. The surgical training apparatus of claim 1, wherein the at least one of a plurality of unique objects is a hook and loop fastener tape set, said set allowing the enhancing of eye-hand coordination and improved manual dexterity by the user performing a practice procedure and instrument manipulation from outside the cavity on the tape set.

3. The surgical training apparatus of claim 1, wherein said mounting and fixedly anchoring means comprises a first, larger foam rubber platform and a smaller, second foam rubber pad, and whereby said one of a plurality of unique objects is attached to said smaller, second foam rubber pad, and said mounting and fixedly anchoring means provides practice exercise on endoscopic technique that mimics real life operating conditions.

4. A simulation method of training and enhancing the skills required of a surgeon in an actual endoscopic procedure comprising the steps of:

a) providing a surgical training apparatus comprising;

i) a box having a plurality of lateral sides, a top side, and a bottom side, and having a cavity therein, said cavity removably containing at least one of a plurality of unique objects simulative of human organs, said at least one of said plurality of objects allowing a particular endoscopic operative procedure to be performed;

ii) access means in at least one of said plurality of lateral sides for allowing said at least one of a plurality of objects to be inserted into and removed from said cavity through said one of said plurality of sides;

iii) means affixed to said box and within said cavity for mounting and fixedly anchoring said at least one of a plurality of objects adjacent said bottom side when said at least one of a plurality of objects is inserted within said cavity, said mounting and anchoring means comprising foam rubber;

iv) one of a plurality of clear and transparent plastic panels slidably and removably affixed to said top side, each of said plurality of clear and transparent panels having a unique pattern of apertures located therethrough, each of said apertures being in receiving engagement with a rubber plate having an opening therethrough, said unique pattern of apertures permitting the practice of said particular operative procedure corresponding to the particular at least one of a plurality of unique objects which is concurrently held within said cavity, the concurrent use of said unique pattern and said at least one of a plurality of unique objects thereby permitting real-life simulation of said operative procedure; and

v) an adjustable pair of mirrors each having a reflective face, one mirror each attached to said box adjacent the top side, each said mirror being adjustably mounted such that each said mirror may be positioned in face-to-face relation to the other said mirror to provide an indirect way of viewing said at least one of a plurality of objects in the cavity during the practice procedure;

b) selecting said at least one of a plurality of unique objects simulative of human organs;

c) inserting said at least one of a plurality of objects so selected through said access means and within said cavity;

d) releasably mounting said at least one of a plurality of objects to said box and within said cavity;

e) selecting said one of a plurality of clear and transparent plastic panels, said panel so selected as to correspond to said at least one of a plurality of unique objects so selected;

f) releasably affixing said one of said plurality of panels so selected to said top side of said box;

g) removably inserting an endoscopic instrument through one of said apertures such that a first end of said instrument is within said cavity while a second end of said instrument is outside said cavity; and

h) manipulating said second end of said instrument to affect actuation of said first end of said instrument such that said actual operative procedure is mimicked.
