Definitions

  • the present invention relates to a ligation device.
  • the inventor (s) now proposes a ligation apparatus that can maintain the ligation state more efficiently than the ligation apparatus or other ligation apparatus introduced through the Korean patent applications throughout this specification.
  • An object of this invention is to provide the ligation apparatus which can maintain a ligation state efficiently.
  • a ligation apparatus comprising a looping string and a tightening member including a passage through which the looped string can pass, wherein the looped string is ligated by the tightening member. And a looped string, wherein the looped string is provided with a ligation device on its at least part surface which includes a barb that prevents the tightening member from moving in the direction in which the ligation is released once ligation is achieved.
  • a ligation apparatus comprising a string, wherein the string is divided into a ligation portion and a mounting portion by a knot formed by a portion thereof, and the string is once ligation is achieved by the knot.
  • a ligation apparatus is provided that includes a barb on at least a portion of the surface thereof such that the knot cannot move in the direction in which the ligation is released.
  • the ligation apparatus which can maintain a ligation state efficiently is provided.
  • FIG. 1 is a view showing the overall structure of the ligation apparatus according to an embodiment of the present invention.
  • FIG. 2 is a diagram illustrating the ligation unit 200 shown in FIG. 1 in more detail.
  • FIG 3 is a view showing the structure of the ligation portion of the ligation apparatus according to another embodiment of the present invention.
  • FIG. 1 is a view showing the overall structure of the ligation apparatus according to an embodiment of the present invention.
  • 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.
  • 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).
  • 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).
  • 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.
  • FIG. 2 is a diagram illustrating the ligation unit 200 shown in FIG. 1 in more detail. This will be described with reference to FIG. 2.
  • the surface of at least a portion of the looped string (corresponding to the ligation portion 210 and the mounting portion 240) (preferably, It can be seen that barb element 241 can be formed. Accordingly, by pushing the tightening member 230 with respect to the ligation portion 210 or by pulling the wire 130 so that the ligation portion 210 to pass more toward the mounting portion 240 through the passage of the tightening member 230. After the ligation is made, the barb element 241 can restrict the tightening member 230 from moving in the direction in which the ligation is released (of course, the tightening member 230 in the direction of making the ligation stronger. Can still move). To this end, the passage of the tightening member 230 may have an inner diameter slightly larger than the thickness of the two strands of the loop-shaped string.
  • FIG 3 is a view showing the structure of the ligation portion of the ligation apparatus according to another embodiment of the present invention.
  • the ligation portion 300 of the ligation apparatus of this embodiment may also be formed including a string.
  • strings may also be synthetic resin strings or flexible metal strings.
  • the ligation portion 310, the knot 320, and the mounting portion 330 may be formed by bending, tying and knotting such strings.
  • the knot 320 may be of any kind that can achieve ligation by pushing towards the ligation portion 310.
  • a plurality barb elements 331 may be formed on the surface of at least a portion of the string. As in the above embodiment, the barb element 331 may function to prevent the knot 320 from moving in the direction of the ligation loosening on the string.
