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:

a puncture handle that is connected via a flexible sheath to a needle body that inserts a ligature member through biomedical tissue;

a pressing handle that is connected to a pressing member that is inserted into the needle body in order to press a holding member that is attached to an end portion of the ligature member;

a ligature tool operation unit that is connected to a ligature sheath that presses a stopper that is penetrated by the ligature member;

a housing in which are fitted the puncture handle, the pressing handle, and the ligature tool operation unit such that each moves freely backwards and forwards;

a first linking device that moves the puncture handle and the pressing handle forward interconnectedly from an initial position where the puncture handle is moved back as far as possible to a tissue puncture position where the puncture handle has moved forward as far as possible and has punctured the biomedical tissue, and releases the link between the puncture handle and the pressing handle at the tissue puncture position; and

a second linking device that engages the ligature tool operation unit with the pressing handle until the tissue puncture position is reached, and moves the ligature tool operation unit forward in conjunction with the pressing handle.

2. The ligature and suture device for medical application according to claim 1, wherein the second linking device pushes the pressing handle forward beyond the tissue puncture state, and the ligature tool operation unit is moved forward in conjunction with the pressing handle until the holding member is pushed out from the needle body.

3. The ligature and suture device for medical application according to claim 1, wherein the second linking device is a device that moves the pressing handle and the ligature tool operation unit forwards and backwards independently relative to the direction in which the pressing handle moves backwards.

4. A ligaturing and suturing method for medical application in which, when biomedical tissue is ligatured using a stopper and a holding member, which are attached to a ligature member, by inserting the ligature member into the biomedical tissue by puncturing the biomedical tissue with a needle body so as to sandwich the biomedical tissue, the method comprising:

a step in which the needle body that houses the holding member is moved forward towards the biomedical tissue;

a step in which, during the time until the needle body penetrates the biomedical tissue, the stopper is moved forward towards the biomedical tissue in conjunction with the needle body;

a step in which, after the needle body has penetrated the biomedical tissue, a pressing member that is inserted in the needle body is moved forward so as to push out the holding member that is housed in the needle body; and

a step in which, after the needle body has been withdrawn from the biomedical tissue, the ligature member that is inserted in the stopper is pulled so that the biomedical tissue is sandwiched by the stopper and the holding member and is ligatured.

5. The ligaturing and suturing method for medical application according to claim 4, further comprising a step in which, after the needle body has punctured the biomedical tissue, the stopper is moved forward in conjunction with the forward movement of the pressing member.

6. The ligaturing and suturing method for medical application according to claim 4, further comprising a step in which, when the needle body is being removed from the biomedical tissue, the needle body is moved backward in conjunction with the backward movement of the pressing member.

7. The ligaturing and suturing method for medical application according to claim 4, wherein when the needle body is being removed from the biomedical tissue, the needle body is moved backwards independently from the stopper.
