Abstract
Abstract A method and apparatus for simulation of conditions under which endoscopic procedures may be practiced by an individual to learn and improve on the skills of manipulation and use of instrumentation and to develop the manual dexterity required. The apparatus has a cavity in which an object simulating a human organ is mounted for performing the practice procedure. The cavity is closeable to outside view or access thus forcing the individual practicing a procedure to use and manipulate the instruments under conditions that mimic real life operating and diagnostic conditions.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
126 words
A simulator for an individual to practice endoscopic procedures used in surgical and diagnostic techniques, comprising: a container having a cavity and said container having at least one aperture providing entry to said cavity for inserting a viewing scope and an instrument to be used to practice a surgical procedure; access means selectively opening said container for setting up a practice procedure and closing said container to prevent viewing of said cavity other than through said viewing scope; means for mounting an object simulating a human organ in the cavity; and, an electrical connector connectable to the object for completing an electrical circuit of an operating procedure using an electrical surgical instrument whereby the individual can practice the operating procedure under conditions closely resembling actual conditions.
Claim 2
Dependent Claim
126 words
A simulator for an individual to practice endoscopic procedures used in surgical and diagnostic techniques, comprising: a container having a cavity and said container having at least one aperture providing entry to said cavity for inserting a viewing scope and an instrument to be used to practice a surgical procedure; access means selectively opening said container for setting up a practice procedure and closing said container to prevent viewing of said cavity other than through said viewing scope; means for mounting an object simulating a human organ in the cavity; and, an electrical connector connectable to the object for completing an electrical circuit of an operating procedure using an electrical surgical instrument whereby the individual can practice the operating procedure under conditions closely resembling actual conditions.
Claim 3
Dependent Claim
39 words
A simulator as defined in claim 1, including; a resilient material covering said aperture, said material having a puncture opening providing resisted penetration to the insertion and movement of instruments for simulating an instrument inserted through an abdominal wall.
Claim 4
Dependent Claim
46 words
A simulator as defined in claim 2, wherein; said access means includes a lid and a side, said lid and said side being openable to provide access to said cavity and being closeable to prevent viewing access to said cavity other than through the viewing scope.
Claim 5
Dependent Claim
18 words
A simulator as defined in claim 3, wherein; said aperture of said container is provided in said lid.
Claim 6
Dependent Claim
40 words
A simulator as defined in claim 4 wherein; multiple apertures are provided in the container for insertion of an object holding instrument for holding the object, and for insertion of a viewing scope and for insertion of a surgical instruments.
Claim 7
Dependent Claim
23 words
A simulator as defined in claim 5 wherein the aperture for the holding instrument is provided in an end wall of the container.
Claim 8
Dependent Claim
32 words
A simulator as defined in claim 6 wherein the mounting means is a clamp suspended from the lid by an adjustable tether for adjusting the position of the object in the container.
Claim 9
Dependent Claim
121 words
A simulator as defined in claim 1 including means for an individual to practice endoscopic procedures used in surgical and diagnostic techniques, comprising: a container having a cavity and said container having at least one aperture providing entry to said cavity for inserting a viewing scope and an instrument to be used to practice a surgical procedure; access means selectively opening said container for setting up a practice procedure and closing said container to prevent viewing of said cavity other than through said viewing scope; means for mounting an object simulating a human organ in the cavity, and means for receiving a liquid circulated through the container whereby the individual can practice the operating procedure under conditions closely resembling actual conditions.
Claim 10
Dependent Claim
24 words
A simulator as defined in claim 8 wherein a tray is mounted under the container for collecting the flow of liquid from the container.
Claim 11
Dependent Claim
128 words
A simulator for an individual to practice endoscopic procedures used in surgical and diagnostic techniques, comprising: a container having a cavity and said container having at least one aperture providing entry to said cavity for inserting a viewing scope and an instrument to be used to practice a surgical procedure; access means selectively opening said container for setting up a practice procedure and closing said container to prevent viewing of said cavity other than through said viewing scope; means for mounting an object simulating a human organ in the cavity; and, said aperture is an elastomeric boot that simulates a cervix entry into a uterus, and the container is configured to simulate the uterus, whereby the individual can practice the operating procedure under conditions closely resembling actual conditions.
Claim 12
Dependent Claim
128 words
A simulator for an individual to practice endoscopic procedures used in surgical and diagnostic techniques, comprising: a container having a cavity and said container having at least one aperture providing entry to said cavity for inserting a viewing scope and an instrument to be used to practice a surgical procedure; access means selectively opening said container for setting up a practice procedure and closing said container to prevent viewing of said cavity other than through said viewing scope; means for mounting an object simulating a human organ in the cavity; and, said aperture is an elastomeric boot that simulates a cervix entry into a uterus, and the container is configured to simulate the uterus, whereby the individual can practice the operating procedure under conditions closely resembling actual conditions.
Claim 13
Dependent Claim
59 words
A simulator as defined in claim 10 wherein the container is a cylinder having a tilted axis defining upper and lower semi-cylinders, animal tissue adhered to the upper and lower semi-cylinders to generate a uterus-like enclosure, and said aperture provided at one end substantially on the cylindrical axis and extended toward the separation between said upper and lower semi-cylinders.
Claim 14
Dependent Claim
51 words
A simulator as defined in claim 11 wherein mounting brackets are mounted on the top and bottom respectively of the top and bottom semi-cylinders, said mounting brackets having a t-shaped head extended into the cavity to be inserted and twisted in the animal tissue for adhering the tissue to the semi-cylinders.
Claim 15
Dependent Claim
28 words
A simulator as defined in claim 12 wherein an electrical connection is connected to a mounting bracket for completing electrical circuitry for use of an electrical surgical instrument.
