Abstract
The present invention relates to an adapter apparatus for medical endoscopes. The present invention comprises an apparatus for inserting tightly into a typical access port of a medical endoscope. Such adapter apparatus permits certain medical implements, such as optical fibers for laser surgery, to be inserted therethrough for treatment of the patient. This adapter apparatus also permits simultaneous passage therethrough of saline or other irrigation fluid without the prior removal of the medical implement. This permits rapid, simultaneous irrigation to proceed directly through an existing endoscope channel.
Claims3
An adapter apparatus for a medical endoscope comprising;
- a) a hollow, cylindrical main body having one opening in each longitudinally opposite end thereof, permitting passage of a thin, long medical implement therethrough;
- b) interior to said main body, a plug dividing the interior region of said main body into an upper and lower region, said plug permitting the passage of said medical implement therethrough, and said plug having therein a one-way means for passage of fluid from the upper region of said main body to the lower region thereof, while preventing passage of fluid in the reverse direction;
- and,
- c) a means for introducing fluid into said upper region of said main body, said fluid having sufficient pressure to pass through said one-way means into the lower region of said body;
- and,
- d) a sealing plug attached longitudinally on the exterior of the lower region of said main body, said sealing plug having size and flexibility to cause a tight seal when inserted in an access port of said endoscope, and said sealing plug having a hole completely therethrough, said hole being in flexible material permitting the passage of said medical implement therethrough while providing a fluid-impermeable barrier therearound;
- and,
- e) a rigid guiding plug longitudinally connecting said main body with said sealing plug, said guiding plug facilitating the passage of said medical implement from said main body through said sealing plug.
The combination of a medical endoscope and an adapter apparatus therefor comprising:
- a) A medical endoscope having access ports on the external, viewing end thereof;
- and,
- b) a hollow, cylindrical main body having one opening in each longitudinally opposite end thereof, permitting passage of a thin, long medical implement therethrough;
- c) interior to said main body, a plug dividing the interior region of said main body into an upper and lower region, said plug permitting the passage of said medical implement therethrough, and said plug having therein a one-way means for passage of fluid from the upper region of said main body to the lower region thereof, while preventing passage of fluid in the reverse direction;
- and,
- d) a means for introducing fluid into said upper region of said main body, said fluid having sufficient pressure to pass through said one-way means into the lower region of said body;
- and,
- e) a sealing plug attached longitudinally on the exterior of the lower region of said main body, said sealing plug having size and flexibility to cause a tight seal when inserted in an access port of said endoscope, and said sealing plug having a hole completely therethrough, said hole being in flexible material permitting the passage of said medical implement therethrough while providing a fluid-impermeable barrier therearound;
- and,
- f) a rigid guiding plug longitudinally connecting said main body with said sealing plug, said guiding plug facilitating the passage of said medical implement from said main body through said sealing plug.
