Abstract

A medical procedure tool equipped with: a flexible linear material for carrying out a specific procedure to a biological tissue; a linear material holding member provided covering the linear material in a freely advancing and retracting manner, for holding the linear material; a flexible first sheath provided so as to come into contact with the base end side of the linear material holding member; a flexible second sheath provided so as to be freely advancing and retracting with respect to the first sheath and the linear material holding member; an operator for advancing and retracting manipulation of the second sheath; and a cutting means for cutting the linear material; wherein the cutting means is provided with a first cutting part provided to the linear material holding member; and a second cutting part that is provided to the front end of the second sheath and which, together with the first cutting part, grips the linear material there between; and one of either the first cutting part or the second cutting part is a blade member.

Claims

1. A medical procedure tool comprising:

a flexible linear material for carrying out a specific procedure to a biological tissue;

a linear material holding member provided covering said linear material in a freely advancing and retracting manner, for holding said linear material;

a flexible first sheath provided so as to come into contact with the base end side of said linear material holding member;

a flexible second sheath provided covering said first sheath and so as to be freely advancing and retracting with respect to said first sheath and said linear material holding member;

an operator that is connected to the base end side of said second sheath and is for advancing and retracting manipulation of the second sheath; and

a cutting means for cutting said linear material;

wherein

said cutting means is provided with a first cutting part provided to said linear material holding member; and

a second cutting part that is provided to the front end of said second sheath disposed farther forward than the first cutting part and which, together with said first cutting part, grips said linear material therebetween; and

one of either the first cutting part or the second cutting part is a blade member.

2. A medical procedure tool according to claim 1, wherein

said first cutting part has a front end guide for guiding said linear material from inside said linear material holding member to the outside, and a base end guide for guiding said linear material that was guided to the outside by said front end guide back inside;

and

said second cutting part is disposed to the position where said linear material exposed to the outside is held between said front end guide and said base end guide part.

3. A medical procedure tool according to claim 2, wherein an opening is on the front end side of the front end of said second sheath, and a slit through which said linear material can be inserted is formed connected to said second cutting part.

4. A medical procedure tool according to claim 2, wherein said second cutting part is provided to a cutting member that freely attaches to and releases from the second sheath.

5. A medical procedure tool according to claim 1, wherein said first sheath is a coil sheath.

6. A medical procedure tool according to claim 1, wherein a reinforcing wire connected to said second cutting part and said operator is fixed in place to said second sheath, along the axial direction thereof.

7. A medical procedure tool according to claim 1, wherein said linear material is a ligating wire for ligating biological tissue.

8. A medical procedure tool according to claim 1, wherein said linear material is a suture material for suturing biological tissue, provided with a pull-out preventing member that is connected to the front end of said suture material, and a suture needle main body for housing said pull-out preventing member and that has a needle part at the front end thereof for penetrating the biological tissue.
