Resumen
Rectoscope intended to be introduced into the ano-rectal cavity of an individual for diagnostic and/or surgical purposes incorporating a radial light source (13), gradually moving, which creates a beam of radial light in order to transilluminate both the tubular body ( 1) of the rectoscope as the portion of the rectum in which it is inserted to allow first an accurate observation of the interior of said cavity and secondly, in case of detecting a foreign body such as a tumor, to be surgically removed, allows a determination accurate of the distal section margin to minimize the rectal portion removed.

1. Rectoscope designed to be inserted in the anorectal cavity of an individual with diagnostic and/or surgical purposes, comprising: - a tubular body (1) of essentially cylindrical and hollow geometry and with translucent walls, comprising in turn a first end (2) intended to be inserted inside the anorectal cavity of an individual and a second end (3) intended to be disposed in the outer part of said cavity, - a hand grip (4) which is projected from the second end (3) of the tubular body (1) for the introduction and handling of the rectoscope, and - an access window (5) of essentially ring-shaped geometry designed to be connected to the second end (3) of the tubular body (1) to regulate access to the inside of said tubular body (1),characterized in that it additionally incorporates a moving radial light source (13), displaceable inside the tubular body (1), designed to create a beam of radial-type light to transilluminates both the tubular body (1) and the portion of the rectum wherein said tubular body (1) is inserted. 2. Rectoscope according to claim 1, wherein the radial light source (13) comprises: - a rod (14) which displaces inside the tubular body (1), comprising in turn a third end (15) and a fourth end (16), - a housing (19) defined in the third end (15) to house a power source of the radial light source (13), - a hinged lid (20) to cover the housing (19), - a ring-shaped support (21), solidly joined to the fourth end (16) of the rod (14), of dimensions slightly less than those of the interior of the tubular body (1), and - a plurality of light sources (22) uniformly distributed on the outer face of the ring-shaped support (21), designed to emit the radial beam of light. 3. Rectoscope according to claim 1, further comprising a moving front light source (23), designed to emit a longitudinal beam of light parallel to the axis of the tubular body (1). 4. Rectoscope according to claims 2 and 3, wherein the front light source (23) is disposed in the front face of the ring-shaped support (21). 5. Rectoscope according to claim 1, wherein the access window (5) additionally comprises: - an opening (6) defined in the centre of the access window (5), - a retractive hatch (7) to cover the opening (6), and - a nozzle (8) designed to connected to an insufflator. 6. Rectoscope according to claim 1, wherein the tubular body (1) comprises the joining of a first outer tube (9) and a second inner tube (10), concentric to the first tube (9) and of smaller diametric dimensions. 7. Rectoscope according to claims 2 and 6, wherein the difference between the diametric dimensions of the first tube (9) and the second tube (10) creates a first hollow channel (11) in the wall of the tubular body (1) wherethrough the rod (14) displaces. 8. Rectoscope according to claim 1, wherein the hand grip (4) additionally incorporates a second channel (17) defined longitudinally on its surface, and a plurality of protuberances (18) defined in the sides of the second channel (17). 9. Rectoscope according to claims 2 and 8, wherein the third end (15) of the rod (14) is of flexible nature to adapt to the curved geometry of the second channel (17) of the hand grip (4). 10. Rectoscope according to claims 2 and 8, wherein the protuberances (18) are distanced from one another in a graduated and uniform manner to discretize the displacement of the third end (15) of the rod (11) throughout the second channel (17). 11. Rectoscope according to claim 2, wherein the light sources (22) are LED diodes. 12. Rectoscope according to claim 3, wherein the front light source (23) are LED diodes.
