Abstract

A ligature and suture device for medical application includes a distal end insertion portion, a needle body, a ligature tool, and an operation section. The operation section includes a housing that is provided in a base end portion of the distal end insertion portion, a puncture handle that is provided in the housing so as to be able to move freely backwards and forwards and that drives the needle body, a pressing handle that is provided in the housing so as to be able to move freely backwards and forwards and that drives a pressing member, a ligature tool operation unit that is provided in the housing so as to be able to move freely backwards and forwards and that drives a ligature sheath, and a ligature handle that is provided in the ligature tool operation unit so as to be able to move freely backwards and forwards and that drives an engaging portion.

Claims

1. A ligature and suture device for medical application, comprising:

an insertion portion configured to be inserted into a body and being provided with at least one side aperture formed on a side at a distal end side of the insertion portion;

a needle body that is provided inside the insertion portion, and that houses inside itself a holding member that is attached to an end portion of a ligature member that is inserted into biomedical tissue, and in which a pressing member that presses the holding member is inserted so as to move freely backwards and forwards, and that punctures biomedical tissue that has been made to bulge into the distal end insertion portion via the side aperture;

a ligature tool that has a flexible ligature sheath that presses a stopper that is penetrated by the ligature member towards the biomedical tissue and hold the biomedical tissue between the holding member and the stopper, and that, at a distal end of an operating wire that has been inserted into the ligature sheath so as to move freely backwards and forwards, is provided with an engaging portion that engages with the ligature member that has been inserted into the stopper; and

an operation section that is provided at a proximal end side of the insertion portion, wherein the operation section comprises;

a housing whose distal end is connected to a proximal end portion of the insertion portion, and configured to be held by an operator;

a puncture handle that is provided in the housing so as to move freely backwards and forwards and that drives the needle body;

a pressing handle that is provided in the housing so as to move freely backwards and forwards and that drives the pressing member;

a ligature tool operation unit that is provided in the housing so as to move freely backwards and forwards and that drives the ligature sheath;

a ligature handle that is provided in the ligature tool operation unit so as to move freely backwards and forwards and that drives the engaging portion;

a handle guide portion being formed at a proximal side of the housing along a longitudinal direction of the housing, the handle guide portion guiding a movement of the pressing handle and the puncture handle mutually substantially in parallel and in a contacting direction;

wherein

the puncture handle, the pressing handle and the ligature tool operation unit including the ligature handle are incorporated integrally in the housing, and attached to the proximal side of the housing,

at least two of the puncture handle, the pressing handle and the ligature tool operation unit are mutually slidable and have portions which mutually contact in the sliding direction, and

the housing guides the at least two of the puncture handle, the pressing handle and the ligature tool operation unit in the contacting direction.

2. The ligature and suture device for medical application according to claim 1, wherein the operation section has a linking device that links the puncture handle with the pressing handle.

3. The ligature and suture device for medical application according to claim 1, wherein the operation section has a linking device that links the ligature tool operation unit with the pressing handle.

4. The ligature and suture device for medical application according to claim 1, wherein the operation section has a linking device that links the ligature tool operation unit with the puncture handle.

5. The ligature and suture device for medical application according to claim 1, wherein the operation section has a linking device that links the puncture handle with the pressing handle and the ligature tool operation unit.

6. The ligature and suture device for medical application according to claim 1, wherein the housing guides the ligature tool operation unit so that the ligature tool operation unit moves substantially parallel to each of the puncture handle and the pressing handle.

7. The ligature and suture device for medical application according to claim 1, wherein the handle guide portion is formed at the proximal side of the housing along a longitudinal direction, the handle guide portion holds the puncture handle, the pressing handle and the ligature handle freely slidably mutually substantially in parallel with respect to the housing.
