Tool for treating excised end of body organ

Abstract

This tool is for treating an excised end of a body organ and is provided with: a long and thin, flexible first band section having a distal end and a proximal end that are made of a biodegradable-absorptive polymer; a long and thin, flexible second band section having a distal end and a proximal end that are made of a biodegradable-absorptive polymer; and a first locking section having a first ratchet claw made of a biodegradable-absorptive polymer, wherein the first locking section is formed at the distal end of the second band section, the distal end of the first band section and the proximal end of the second band section are joined together, at least one ratchet tooth that is capable of meshing with the first ratchet claw is formed on the external surface of the first band section, and the engagement of the ratchet tooth with the first ratchet claw forms a flattened ring which is used to bind a body organ so as to ligate a tube or cavity that opens at an excised end of the body organ.

1 - 8 . (canceled) 
     
     
         9 . An organ stump treatment tool, comprising
 an elongated flexible band portion having a distal end and a proximal end, and   a locking portion comprising a second interlocking part,   wherein the locking portion is at the distal end of the band portion,   the band portion comprises a row of holes, wherein the holes are configured to pass a thread through, and   the band portion comprises a first interlocking part for meshing engagement with the second interlocking part,   whereby the meshing engagement of the first interlocking part with the second interlocking part makes a ring, and the ring binds an organ tightly to ligate a duct or lumen that opens at a stump of the organ.   
     
     
         10 . The organ stump treatment tool according to  claim 9 , wherein the second interlocking part comprises a first ratchet pawl, the first interlocking part comprises at least one ratchet tooth capable of being meshed with the first ratchet pawl. 
     
     
         11 . The organ stump treatment tool according to  claim 9 , wherein the band portion has an inner surface where at least one convex strip is formed to extend in a lengthwise direction. 
     
     
         12 . The organ stump treatment tool according to  claim 9 , further comprising a tongue part, in the vicinity of the first locking portion, for preventing an organ tissue from getting caught in the organ stump treatment tool. 
     
     
         13 . The organ stump treatment tool according to  claim 10 , further comprising a second locking portion comprising a second ratchet pawl, wherein
 the first ratchet pawl is allowed to be released from meshing engagement with the ratchet tooth even meshed with the first ratchet pawl, and the second ratchet pawl is prohibited from being released from mashing engagement with the ratchet tooth once meshed with the second ratchet pawl.   
     
     
         14 . The organ stump treatment tool according to  claim 9 , wherein the elongated flexible band portion is made of a biodegradable and bioabsorbable polymer, and the locking portion is made of a biodegradable and bioabsorbable polymer. 
     
     
         15 . The organ stump treatment tool according to  claim 14 , wherein the second locking portion is made of a biodegradable and bioabsorbable polymer. 
     
     
         16 . The organ stump treatment tool according to  claim 9 , further comprising a covering member. 
     
     
         17 . The organ stump treatment tool according to  claim 16 , wherein the covering member is made of a biodegradable and bioabsorbable polymer. 
     
     
         18 . The organ stump treatment tool according to  claim 9 , wherein the holes are aligned in a lengthwise direction of the band portion.
