Abstract

An internal treatment apparatus for a patient having a flexible tubular body to be introduced into a patient includes a center opening for inserting therethrough an endoscope for observing a target site, the center opening being circular in cross section and disposed at a center of an end face of the flexible tubular body; and a plurality of circumferential apertures through which surgical instruments are inserted for performing a surgical procedure on the target site, the plurality of circumferential apertures being provided in the flexible tubular body at equi-angular intervals around the center opening.

Claims

1. An internal treatment apparatus for a patient comprising a flexible tubular body to be introduced into a patient, said flexible tubular body comprising:

a center opening and an endoscope inserted through said center opening for observing a target site, said center opening extending through said flexible tubular body from a center of a flat distal end face of said flexible tubular body, said flat distal end face facing said target site, said center opening having an outlet with an outlet perimeter lying in a common plane with said flat distal end face,

a distal end portion having a circular cross section with the outer diameter thereof reduced toward its distal end to said flat distal end face, and

a plurality of circumferential holes through which surgical instruments are inserted for performing a surgical procedure on said target site, each of said plurality of circumferential holes being provided proximally of said distal end portion having a reduced diameter and extending through a side face of said flexible tubular body so that each of said plurality of circumferential holes is independent from said flat distal end face, and each of said plurality of circumferential holes is distinct from said center opening.

2. The internal treatment apparatus for a patient according to claim 1, wherein said flexible tubular body comprises a resiliently deflectable portion, and a circumferential opening portion includes said plurality of circumferential holes, and the circumferential opening portion passes through said flexible tubular body from a side face of the deflectable portion toward a proximal end face of said flexible tubular body.

3. An internal treatment system for a patient comprising:

a flexible tubular body to be introduced into a patient, said flexible tubular body including a center opening and an endoscope inserted through said center opening for observing a target site, said center opening being circular in cross section and extending through said flexible tubular body from a center of a flat distal end face of said flexible tubular body, said distal end face facing said target site, said center opening having an outlet with an outlet perimeter lying in a common plane with said flat distal end face, a distal end portion having a circular cross section with the outer diameter thereof reduced toward its distal end to said flat distal end face, and a plurality of circumferential holes through which surgical instruments are inserted for performing a surgical procedure on said target site, each of said plurality of circumferential holes being provided proximally of said distal end portion having a reduced diameter and extending through a side face of said flexible tubular body at a distal end of said flexible tubular body, so that each of said plurality of circumferential holes is independent from said flat distal end face, and each of said plurality of circumferential holes is distinct from said center opening;

a body manipulating device for manipulating said flexible tubular body from outside said patient;

an endoscope manipulating device for manipulating said endoscope from outside said patient; and

a surgical instrument manipulating device for manipulating said surgical instruments from outside said patient.

4. The internal treatment system for a patient according to claim 3, wherein said flexible tubular body comprises a resiliently deflectable portion, and a circumferential opening portion includes said plurality of circumferential holes, and the circumferential opening portion passes through said flexible tubular body from a side face of the deflectable portion toward a proximal end face of said flexible tubular body.
