Disposable surgical scope guide
First Claim
1. A post-operative, disposable medical scope guide, comprising:
- an elongated flexible, lightweight tube having outer and inner ends and being adapted for partial insertion into a body cavity through a surgical incision to locate said inner end within the body cavity and to locate said outer end outside the body cavity;
said tube having a primary passage extending between said outer and inner ends through which a removable scope means is selectively passed, said primary passage of said tube having a larger diameter than the diameter of said scope means so to provide clearance between said scope means and said tube when said scope means is positioned within said tube;
a transparent inflatable balloon secured to said inner end of said tube;
said primary passage being unobstructed between said inner and outer ends of said tube to define an unobstructed opening into said balloon through which said scope means passes into balloon for viewing internal body tissues;
a sealable airtight means adjacent the outer end of said tube for sealing closed the tube and for maintaining the internal sterility of the tube and being adapted to slidably receive said scope means; and
means for selectively introducing and releasing air into and from said balloon for inflation and deflation thereof.

Abstract
A medical scope guide allows internal body tissues to be viewed. The scope guide includes an elongated hollow tube having opposite inner and outer ends, and a transparent inflatable balloon secured to the inner end of the tube. The outer end of the tube is sealable and is adapted to slidably receive a scope device which extends through the tube and into the balloon. Air can be introduced and released through the tube into and from the balloon for inflating and deflating the balloon. In order to view the internal body tissues, a surgical incision is made in the body of the patient and the scope guide is inserted through the incision such that the inner end of the tube is located within the body and the outer end of the tube is located outside the body. The scope is inserted through the tube and into the balloon and the balloon is inflated so as to engage the body tissues to be observed. The body tissues are viewed with the scope device, which is removed from the scope guide when viewing is completed. The scope guide can remain in position in the body for later viewing of the tissues.

8. The method of visually examining and monitoring internal post-operative body tissues within the body of a patient, comprising:
-
making an surgical incision in the body of a patient to gain access to internal body tissues within the patient; operatively treating said internal body tissues; inserting through said incision the inner end of a hollow elongated scope guide having a lateral dimension substantially smaller than said surgical incision and having a transparent balloon on said inner end, with said inner end being positioned adjacent said body tissues and with the outer end of said guide being positioned outside said incision; closing said incision around said guide; inflating said balloon into engagement with the tissues to be observed; inserting the viewing end of an elongated scope device into said guide, and moving said viewing end into said balloon member; viewing said body tissues with said scope device through said transparent balloon after treatment of the tissues so as to monitor the reaction of the tissues to the treatment.
