This is a Continuation In-part Application (CIP) based on U.S. patent application Ser. No. 11/809,488, titled “MEDICAL TREATMENT ENDOSCOPE”, filed Jun. 1, 2007, which is a CIP based on U.S. patent application Ser. No. 11/652,880, titled “MEDICAL TREATMENT ENDOSCOPE”, filed Jan. 12, 2007, which is a CIP based on U.S. patent application Ser. No. 11/435,183, titled “MEDICAL TREATMENT ENDOSCOPE”, filed May 16, 2006, which is a CIP based on U.S. patent application Ser. No. 11/331,963, titled “MEDICAL TREATMENT ENDOSCOPE”, filed Jan. 13, 2006.
As illustrated in FIG. 1, an endoscope insertion section 503 fully integrated with a medical treatment endoscope 501 extends from an end of an endoscope insertion section 502. An elongated and flexible endoscope insertion section 503 has the same structure as those of the U.S. patent application Ser. Nos. 11/435,183 and 11/652,880. That is, the endoscope insertion section 503 has a first sheath 301 having a first arm section 302A and a second arm section 302B on the tip of the first sheath 301. Treatment sections 505A and 505B of procedure instruments 504A and 504B each protrude from the tips of the arm sections 302A and 302B. A first bending part 306 and a second bending part 308, in this order from the tips of the arm sections 302A and 302B, are formed to each arm section 302A and 302B. Combined use with a third bending section 203B formed in the first sheath 301 enables a bending operation in a human body. The first and second arm members 302A and 302B may be inserted into another sheath protruding from the tip of the sheath 301 as disclosed by the U.S. patent application Ser. No. 11/652,880. Meanwhile, the operation section 520 is enlarged in FIG. 1 to help better understanding.
The tip of the connection plate 713 is joined to the second bending slider 711 by a fulcrum pin 721 and extends substantially parallel in the axial line from here toward the ratchet base 712. The recessing shape of the first groove 718 allows the engagement chip 717A of the piston 715 to enter there, and a midpoint of the wall surface of the tip portion of the first groove 718 forms an inclination surface 718A. The inclination surface 718A gradually widens the first groove 718 from the midpoint to the tip portion. A second groove 719 is formed at a further tip portion than the first groove 718 is formed. The recessing shape of the second groove 719 allows the engagement chip 717A of the piston 715 to enter there. The second groove 719 is deeper than the first groove 718. The base end wall surface of the second groove 719 forms an inclination surface 719A. The inclination surface 719A gradually widens the second groove 719 toward the tip portion. The first groove 718 is positioned so that the second bending part 308 of the first arm member 302A as illustrated in FIG. 1 becomes straightened. The second groove 719 is positioned so that the second bending parts 308 bend to open the first arm member 302A. This allows the arm section 302A to close by engaging the first groove 718 with the piston 715, and allows the second arm member 303A to open by engaging the second groove 719 with the piston 715. As previously described, the engagement of the piston 715 with the grooves 718 and 719 can be released with a small force since the inclination surfaces 718A and 719A are formed in the grooves 718 and 719. This facilitates smooth switching of the engagement position of the piston 715 with the grooves 718 and 719. As illustrated in FIG. 23, the spring 791 forces the second bending slider 711 and the connection plate 713 to be positioned toward the tip portion by the spring force when the procedure instrument 504A is not inserted and thus, the first groove 718 engages with the piston 715. As illustrated in FIG. 25, the piston 715 is pushed by the operation section 506A of the procedure instrument 504A when the procedure instrument 504A is inserted. Since this state of the engagement chip 717A can move up the inclination surface 718A, the second bending slider 711 can be drawn, and the second bending part 308 can be opened. In this configuration, the procedure instrument 504A must be inserted to draw the second bending slider 711 because the tip of the procedure instrument 504A can hardly be passed through the opening state of the second bending part 308. As illustrated in FIG. 27, the engagement chip 717A makes contact with the inclination surface 719A as long as the second bending slider 711 is drawn toward the base end. The tension applied by the second bending wires 316A and 316B urges the slider 711 toward the tip. As illustrated in FIGS. 28 and 29, raising the piston 715 necessitates a significant force if the disposition angle of the inclination surface 719A is significantly equal to 90°. If the disposition angle is substantially horizontal, the piston 715 is spontaneously raised by the tension applied by the second bending wires 316A and 316B and therefore, the second bending slider 711 moves toward the tip, and the second bending part 308 closes. The suitable angle α of the inclination surface 719 is 60°≦α≦90°.
