There are some technologically advanced scopes out there that do some amazing things. Many of them share similar qualities and features. An articulating borescope, for example, shares many similarities with a rectal scope.
Both Scopes Use Cameras to See and Take Pictures
While a rectal scope takes pictures of the human colon and internal, visceral structures, the borescope takes pictures of everything from rust you cannot see inside a car panel to tiny living creatures living inside a well. Both of these types of scopes are not only equipped to see inside places the naked eye cannot, but also take photos of concerned and disconcerting areas.
Both Scopes are Extremely Flexible
Both a rectal scope and a borescope are designed to be extremely flexible. Given the sensitive nature of both of their jobs, it is vital to the scope's operator that the either scope bend and move around in multiple directions. The rectal scope has to move through several twists and turns of the large and small colons, while the borescope has to pivot and peek into corners inside solid objects.
Both Scopes Have Lights
Obviously, you or a doctor would not be able to use a scope and see much of anything without a light. Instead of inserting a source of light into the area that the borescope or rectal scope is attempting to see, both types of scopes are equipped with their own light source. A button the on the handheld section of the borescope or on the dashboard and screen of the rectal scope turns the light on so the operator of the scope can see and manipulate where either scope goes.
Both Scopes Can Be Retracted Like Line on a Fishing Rod
Borescopes and rectal scopes both have a manual turn handle that resembles a fishing reel. When the operator of either type of scope needs to back up or withdraw the scope, he or she only needs to use the winding handle to move the scope in one direction or another. This provides the operator more control on how to remove the scope as well as how quickly to move the scope in or out of the intended inspection area.
Similarities Does Not Mean Sameness
Despite the fact that these two types of scopes are very similar in nature, features and function, you should never use a borescope for internal human exams, nor should you use a rectal scope for examining the interior of inanimate objects. Even though both types of scopes are also waterproof, the rectal scope is softer and more easily damaged by sharp objects. Likewise, an articulating borescope would not be as gentle on internal organs as the rectal scope.
