Abstract

An endoscopic treatment device is used with an endoscope. This treatment device includes a transmission member with a flexible structure having a distal end portion to be inserted into a body and can be operated outside the body, a push rod coupled to the distal end portion, and first and second connecting members rotatably coupled to the push rod. The treatment device further includes first and second arm members rotatably coupled to the distal end portion of the connecting member, a holding member rotatably holding the respective arm at a predetermined interval therebetween, and first and second actuating members integrally formed with the arm members and can open/close when the transmission member actuates the first and second connecting members and the first and second arm members through the push rod. This device also includes a needle mounted on at least one of the first and second actuating members.

Claims

1. A treatment device that is elongated in an axial direction and which is used together with an endoscope to perform treatment in a body by being operated outside the body, comprising:

a needle which is used to puncture a living tissue and to which a thread for suturing the tissue is fixed;

a recovery member capable of recovering the needle inserted into the tissue, the recovery member having an outer periphery portion at which a groove is provided, and an inner hole;

a guide formed in an elongated and tubular shape and capable of guiding the recover member;

an elongated circular member capable of being inserted into the guide; and

at least one arm provided at a distal end of the elongated circular member,

the groove having an annular form, and being engageable with the at least one arm at a plurality of points, wherein when the groove and the at least one arm are located in the guide, the recovery member and the elongated circular member keeps an engagement with each other, and the recovery member is movable in the guide only in the axial direction by the elongated circular member.

2. A treatment device according to claim 1, wherein the arm is made of an elastic member.

3. A treatment device according to claim 1, wherein the arm is made of an elastic metal.

4. A treatment device according to claim 1, wherein the at least one arm comprises two arms provided at positions facing each other.

5. A treatment device according to claim 1, wherein the elongated circular member has an expansion proof member which is formed of at least one wire along the elongated circular member so as to prevent expansion.
