Preferred Embodiments of the Invention

As shown, the ligation apparatus may include an extension part 100 and a ligation part 200. The extension part 100 may be an elongated component that allows the ligation part 200 to extend to a part (eg, blood vessel, tissue, part of an organ, etc.) that requires ligation of the body. One end of this may be connected to the ligation unit 200 for tying the above portion. See below for more details.

First, the extension part 100 includes a main body 110 including a hollow inside thereof, a hook 120 having a hook shape and the like, which can hold a part of the ligation part 200, and a hook 120. Connected to), it may include a wire 130 that can pull the ligation unit 200 by going to the hook (120).

Next, the ligation portion 200 may include the ligation portion 210, the tip portion 220, the tightening member 230 and the mounting portion 240. At least the ligation portion 210 and the mounting portion 240 of the above components may be one loop type string divided into two parts by the fastening member 230. Such a looped string may be a synthetic resin string or a flexible metal string.

The ligation portion 210 is one annular component of the looped string that can be pulled toward the extension 100 accordingly when the wire 130 is pulled according to a user's operation to achieve a predetermined ligation. Can be.

The tip portion 220 may be formed on a portion of the ligation portion 210. This tip portion 220 is designed to maintain the distinction between the ligation portion 210 and the mounting portion 240, i.e., so that the ligation portion 210 does not fall all over the tightening member 230, the tightening member It may be formed thicker than the inner diameter of the passage in (230). In FIG. 1, the tip portion 220 is illustrated as a string-like component, which is padded on the ligation portion 210, but as long as it functions as described above, the shape thereof is not particularly limited.

The tightening member 230 may include a passage through which the looped string may pass, and may be a member that functions to tighten and fix the ligation formed by the ligation portion 210 so as not to be easily released. This tightening member 230 will be described later.

Mounting portion 240 may be another annular component of the looped string that may be grabbed by hook 120 to cause the looped string to be pulled toward extension 100. The distinction between the mounting portion 240 and the ligation portion 210 is maintained by the tightening member 230, but the length of the two portions may vary depending on the position of the tightening member 230.
