Description

Surgical suture tools

The present invention relates to a surgical suture tool, and more particularly, to a surgical suture tool for forming a knot in a suture portion inside the body in a state in which a passage through the body from outside the body is narrow.

In surgery, suture refers to stitching and attaching cracks in living tissues or cuts to perform surgery. In other words, surgical suture is a medical practice used to attach and maintain body tissues torn or incised during surgery, and it is used to sew split living tissues using a suture with a needle and form a knot to fix the split living tissues. .

On the other hand, in the case of surgery in which a living body tissue is located inside the body, such as spinal endoscopy and nasal endoscopy, and the passage from the outside to the inside of the body is narrow, Difficulties existed in forming the suture knot.

In general, in order to form a knot in the suture area, a knot was made with both ends of the suture after the suture was sewn, and both sides of the knot were pulled by hand to adhere the knot to the suture area. However, in the case of surgery with a narrow passage from the outside of the body to the inside of the body, such as endoscopic surgery, there is a problem that it is difficult to adhere the knot to the suture area because there is not enough space for pulling the knot on both sides.

Further, the diameter of the first shaft 200A may be substantially the same as or less than the distance between the third hole 130 and the fourth hole 140. For this reason, it is possible to secure a more detailed suture by securing a field of view for the knot A to be described later in FIGS. 5 to 11.

5 to 11 are views showing a process of suturing a living body through the surgical suture tool 10 according to an embodiment of the present invention.

In general, in order to form a knot in the suture portion 301, a knot (A) is formed with both ends of the suture 310 by which the suture portion 301 is sewn, and the suture portion 301 by pulling both ends of the knot (A) by hand. The knot (A) was taken in close contact with each other. However, in the case of surgery where the passage from the outside of the body to the inside of the body is narrow, such as endoscopic surgery, there is not enough space to pull the knot A to both sides by hand, so it is difficult to adhere the knot A to the suture 301 I can. In the case of surgery in which the passage from the outside of the body to the inside of the body is narrow, the surgical suture tool 10 according to an embodiment of the present invention attaches a knot A to the suture portion 301 through the process of FIGS. 5 to 11. You can make it close.

Referring to FIG. 5, the suture part 301 may be a part of the living body 300 that is located inside the body and is torn or incised during surgery. The diameter of the plate 100, the first shaft 200A, and the second shaft 200B constituting the surgical suture tool 10 may be smaller than the diameter of the passage from the outside of the body to the suture 301 inside the body. Accordingly, the surgical suture tool 10 may reach the suture portion 301 inside the body from the outside of the body.

6, the knot (A) may be formed outside the body, the knot (A) may be an over hand knot (over hand knot).

Referring to FIG. 7, the knot A may be attached to the front surface of the plate 100 of the surgical suture tool 10. The knot (A) may be moved toward the suture portion 301 according to the force pushing the surgical suture tool 10 in the moving direction (md).

In more detail, a view of the front surface 131 of the plate 100 in which the knot A portion of FIG. 7 is attached to the surgical suture tool 10 is shown in FIG. 15. 7 and 15 together, the knot A is shouldered to the front surface 131 of the plate 100, and the suture 310 extending to both sides of the knot A is formed with the first hole 110 2 Arranged to pass through the hole 120, the knot of the suture 310 moves toward the suture 301 as the surgeon generates a force that directs the surgical suture tool 10 in the moving direction (md). Can be.

At this time, in order to ensure that the suture 310 is not broken and the knot A is in close contact with the suture 301 stably, the force generated in the suture 310 when the surgical suture tool 10 is pushed in the moving direction md It should be less than the tension that the suture 310 can withstand. At the same time, when the surgical suture tool 10 is pushed in the moving direction (md), the force generated on the suture 310 acts on the suture 310 and the front surface 131 of the plate 100 (the kinetic friction force is Since it is smaller than the static friction force, reference to the kinetic friction force will be omitted) so that the knot A can move up to the suture portion 301.

In other words, the force that must be generated in the suture 310 so that the knot A can move is greater than the static friction force and less than the tension that the suture can withstand, the knot (A) without breaking the suture 310 This can be moved, and at this time, as the magnitude of the static friction force is reduced, the knot A can be moved to the suture portion 301 with a small force, so that the suture 310 does not break while applying a force to the knot A. can do.

The structure of the plate 100 according to the embodiment of the present invention minimizes the static friction force required for the knot A to move as follows, so that the knot A is in close contact with the suture part 301 even with a small force To be able to.

Referring back to FIGS. 7 and 15, a part of the suture 310 extending to both sides of the knot A and the knot A may be attached to the front surface 131 of the plate 100. The force pulling the knot (A) to both sides occurs in the suture 310 of the portion that is shouldered to the front surface 131 of the plate 100, and at this time, the front surface 131 that is shouldered with the sutures 310 on both sides of the knot (A) The longer the length, the smaller the static friction. To this end, the length of the front surface 131 to which the suture 310 is attached may be formed to be longer than the length of the

holes

110 and 120, and as an example, the first hole 110 and the suture 310 are attached. The length of the front surface 131 and the second hole 120 may be formed in a ratio of 1.0:3.5:1.0. However, the ratio of the plate 100 shown in FIG. 15 is only an example, and the illustrated ratio is not intended to limit the invention.

In addition, a static friction force acts on a portion where the sutures on both sides of the knot A are bent toward the first hole 110 and the second hole 120. At this time, the

holes

110 and 120 are connected to a curved surface without irregularities or steps from the front surface 131 of the plate 100, and the portions forming the

grooves

210 and 220 are the portions forming the

holes

110 and 120 and the irregularities. Alternatively, by forming to be connected to a curved surface without a step, it is possible to minimize the static friction force for the suture 310 to move.

In addition, the third groove 230 and the fourth groove 240 create a space in which the knot A is exposed to the outside in a state in which the plate 100 is in contact with the suture 301, and the knot A You can secure a view to see the state of. When the plate 100, the first shaft 200A, or the second shaft 200B includes a light-transmitting material, it may be easy to check the state of the knot A in close contact with the sealing portion 301.

According to the above-described principle, as shown in FIGS. 8 and 9, the surgical suture tool 10 minimizes the static friction force, which is a condition for causing the suture 310 to move on the plate 100, so that the knot A This suture portion 301 is not broken and is stably adhered to each other.

10 and 11, the second knot B may be formed outside the body spaced apart from the first knot A. Thereafter, as the process of FIGS. 6 to 8 is repeated, the surgical suture tool 10 may move the second knot B toward the first knot A. The second knot B may be in close contact with the first knot A. As the first knot (A) and the second knot (B) are in close contact, the suture can be made more stable and strong.

Referring to Figure 12, the surgical suture tool (10a) may include a plate (100a) and a shaft (200a). The plate 100a may include a U-shaped first hole 110a and a second hole 120a. Unlike the surgical suture tool 10, the surgical suture tool 10a may not include a hole corresponding to the third hole 130 and the fourth hole 140.

Referring to Figure 13, the plate (100b) is a flat plate portion (101b), a first side part (102b) extending from the flat plate portion (101b) and inclined rearward, and the plate portion (101b) extending and inclined rearward. It may include a second side part 103b. The first side part 102b and the second side part 103b may face each other. When the first side part 102b and the second side part 103b are inclined backward, when the knot A is in close contact with the suture part 301 using the surgical suture tool 10b, the first side The part 102b and the second side part 103b may not be in contact with the sealing part 301. When the knot A is in close contact with the suture portion 301 using the surgical suture tool 10b, only the flat portion 101b may contact the suture portion 301. By minimizing the contact area between the surgical suture tool 10b and the suture portion 301, stimulation applied to the suture portion 301 can be minimized.

The first hole 110b and the first groove 210b may communicate, the second hole 120b and the second groove 220b may communicate, and the third hole 130b and the third groove 230b ) Can communicate.

Referring to FIG. 14, the plate 100c may include a protrusion 101c protruding toward the front. When the protrusion 101c is formed, when the knot A is in close contact with the suture 301 using the surgical suture tool 10c, only the protrusion 101c can contact the suture 301. By minimizing the contact area between the surgical suture tool 10c and the suture portion 301, stimulation applied to the suture portion 301 can be minimized.

The first hole 110c and the first groove 210c may communicate, the second hole 120c and the second groove 220c may communicate, and the third hole 130c and the third groove 230c ) Can communicate.
