Description

Hemostasis device {HEMOSTASIS DEVICE}

The present invention relates to a hemostasis device, and more specifically, to a hemostasis device for hemostasis from bleeding caused by perforation of a blood vessel in the human body.

In the human body, bleeding occurs when a blood vessel is perforated and blood from the blood vessel is discharged to the outside. It is divided into non-invasive hemostasis and invasive hemostasis. Non-invasive hemostasis is a method of hemostasis by applying pressure from the outside of the skin to the blood flowing out of the path leading to the punctured blood vessel and the skin using a hemostatic pad or compression device.

Invasive hemostasis is a method of hemostasis that occurs by sewing the punctured blood vessel with biodegradable thread or suturing it with a polymer such as collagen, instead of compressing the punctured blood vessel.

Conventionally, invasive hemostasis involves inserting a circular or non-circular anchor that can adhere closely to the punctured position of the blood vessel into the blood vessel and attaching a polymer such as collagen to the outside of the blood vessel.

However, this method of sealing the punctured location by arranging the anchor and polymer inside and outside based on the blood vessel wall may cause cases where the adhesion between the anchor and the polymer decreases due to the pulsation and pressure of the blood vessel itself and the patient's movement. There is a problem that rebleeding occurs frequently due to this. In particular, this conventional invasive method of hemostasis has the problem that rebleeding frequently occurs during the process of a patient waking up from a procedure under general anesthesia, recovery, and the process of moving the patient.

US Patent No. 10149670 (2018.12.11.) US Patent No. 11013504 (2021.05.25.)

Embodiments of the present invention were invented against the above background, and are intended to provide a hemostatic device that can minimize the occurrence of rebleeding even after hemostasis of a blood vessel punctured in an invasive manner.

According to one aspect of the invention, an anchor is placed inside the blood vessel through the punctured location of the blood vessel; a wire connected to the anchor; a compression member inserted into the wire and disposed outside the blood vessel at the punctured location of the blood vessel; And a hemostasis device may be provided, which has the shape of a tube into which the wire is inserted and includes a first fixing member for pressing the pressing member.

One or more locking protrusions may be formed on the outer surface of the first fixing member to be fixed to the skin outside the blood vessel, or one or more locking protrusions may be formed on the outer surface of the wire or itself to be fixed to the skin outside the blood vessel.

A hemostasis device may be provided in which the one or more locking protrusions have a direction in which the first fixing member can be moved in a direction in which the pressing member is pressed.

A hemostasis device may be provided, further comprising a second fixing member disposed on the wire to press the first fixing member.

A device may be provided.

In one embodiment of the present invention, the anchor and the pressure member are in close contact to stop bleeding at the punctured location of the blood vessel, and the pressure member is continuously compressed using the first fixing member and the second fixing member to puncture the blood vessel. This can prevent rebleeding from occurring at the site.

In addition, since hemostasis is performed using biodegradable materials for the anchor, wire, pressure member, first fixation member, and second fixation member for hemostasis at the punctured location of the blood vessel, they biodegrade after a certain period of time and no foreign substances remain, allowing for puncture. It has the effect of restoring the previous state.

Referring to the drawings shown in FIGS. 1 to 7, a hemostasis device 10 according to an embodiment of the present invention will be described. The hemostasis device 10 according to an embodiment of the present invention includes an anchor 100, a wire 200, a pressing member 300, a first fixing member 400, a second fixing member 500, and a first tube ( 610), a second tube 620, a third tube 630, a fourth tube 640, and a transmitter 700.

The anchor 100 is connected to the wire 200 and may have a bar shape or a plate shape with a predetermined length. This anchor 100 may be placed inside the blood vessel 20 by passing through the location where the blood vessel 20 of the human body was punctured. A locking portion 110 for binding the wire 200 may be formed in the anchor 100.

The catching portion 110 is disposed in the middle portion of the anchor 100, and a predetermined hole may be formed through which the wire 200 can pass. The locking portion 110 may be formed to have a ring on the anchor 100. In the drawing according to this embodiment, the ring is shown as being circular, but the ring may be configured in a shape other than circular.

One end (tip end) of the wire 200 may be connected to the anchor 100. This wire 200 may be disposed in a state where two wires 200 overlap, passing through the catching portion 110 of the anchor 100 to the second fixing member 500 . The wire 200 may extend through the pressing member 300 multiple times along the longitudinal direction of the pressing member 300. Additionally, the pressing member 300 may be alternately positioned on one side of the pressing member 300 and the other surface of the pressing member 300 while extending along the longitudinal direction. This wire 200 may be arranged to have a predetermined length from the second fixing member 500 to the outside and may extend to the transmitter 700.

The wire 200 may be made of a material that can be inserted into the human body and fuse with the human body after a predetermined period of time has elapsed. This wire 200 may be formed of, for example, a biodegradable material in the form of a suture.

The pressing member 300 is made of a flexible material and may have a predetermined length and width. The length of the pressing member 300 may be relatively larger than the width. As shown in FIG. 2 , the pressing member 300 may be disposed by partially penetrating the wire 200 and being inserted into the wire 200 . The wire 200 may penetrate the pressing member 300 at a predetermined interval in the longitudinal direction of the pressing member 300.

Accordingly, when an external force is applied toward the position where the anchor 100 is placed, the pressing member 300 may be deformed in shape to be folded or bundled with respect to the wire 200.

The compression member 300 may be formed of a polymer material that can be inserted into the human body and fused to the human body after a predetermined period of time. For example, the compression member 300 may be formed of a collagen material. It can be.

The first fixing member 400 has a predetermined length and may have a substantially cylindrical shape. The first fixing member 400 may have a cylindrical shape with the wire 200 passing through it, and may be disposed at a rear end of the pressing member 300. That is, the pressing member 300 may be disposed between the anchor 100 and the first fixing member 400.

In this embodiment, the catching protrusion 410 is disposed on the outer circumferential surface of the first fixing member 400, but it is not limited thereto, and as shown in FIG. 3, the outer surface of the wire 200 or the wire 200 The main body itself may have the form of a locking protrusion 410.

The first fixing member 400 may be moved along the wire 200 by an external force, and is in contact with the pressing member 300 to press the pressing member 300 toward the anchor 100 by the external force. ) can change its shape.

Here, the first fixing member 400 is placed within the skin of the human body when the anchor 100 is placed within the blood vessel 20. Accordingly, a plurality of locking protrusions 410 may be formed on the outer peripheral surface of the first fixing member 400 so that the pressing member 300 can be maintained in a state in which the first fixing member 400 presses the pressing member 300.

A plurality of locking protrusions 410 are disposed on the outer peripheral surface of the first fixing member 400, and may be oriented so that the first fixing protrusions can be pressed in one direction within the skin. That is, the catching protrusion 410 is formed to protrude in the radial direction on the outer peripheral surface of the first fixing member 400, and may be formed inclined toward the opposite side of the anchor 100 (the rear end side of the wire 200). And the end of the stopping protrusion 410 may have a sharp shape. Therefore, when the first fixing member 400 is placed within the skin, the plurality of locking protrusions 410 may become embedded in the skin and may not move arbitrarily. In other words, the stopping protrusion 410 can prevent the first fixing member 400 from moving in the direction opposite to the direction in which the pressing member 300 is pressed. As the catching protrusion 410 is inclined toward the rear end of the wire 200, the first fixing member 400 can be moved in only one direction.

The first fixing member 400 may be made of a material that can be inserted into the human body and blend into the human body after a predetermined period of time has elapsed, and a material having a predetermined strength may be used.

Additionally, if necessary, the first fixing member 400 may be omitted, and the wire 200 itself may be used with a protrusion shape such as a plurality of catching protrusions 410 formed thereon.

The second fixing member 500 may be disposed at a rear end than the first fixing member 400. That is, the first fixing member 400 may be disposed between the pressing member 300 and the second fixing member 500. The second fixing member 500 may apply an external force to the first fixing member 400 as it is disposed at the rear end of the first fixing member 400 .

For example, the second fixing member 500 may be formed by tying the wire 200 into a knot. In this embodiment, the wire 200 returns through the catching portion 110 of the anchor 100 and is tied to the wire 200 to form a knot corresponding to the second fixing member 500. Accordingly, the wire 200 may be formed into a ring by the second fixing member 500.

Here, the knot forming the second fixing member 500 may be formed as a pulling knot, and the pulling knot is such that when the wire 200 is pulled in a predetermined direction, the first tube 610 is connected to the second fixing member ( It is a knot that moves when pressurizing 500) in the direction where the anchor 100 is located. This pull knot is a different type of knot than a noose knot in which when the wire 200 is pulled in a predetermined direction, the knot moves in the opposite direction to the direction in which the wire 200 is pulled.

Therefore, when an external force acts on the wire 200 disposed at the rear end of the second fixing member 500 to pull the wire 200 in the rear end direction and the first tube 610 presses the second fixing member 500 The second fixing member 500 may be moved in the direction (shear direction) of the anchor 100, and the second fixing member 500 may press the first fixing member 400.

As described above, the second fixing member 500 may be formed as a pull knot, but is not limited thereto. When an external force is generated in the rear end direction on the wire 200, the second fixing member 500 may be used as an anchor. Any configuration in which (100) moves only in the direction in which it is placed can be used.

The first tube 610 is disposed at the rear end of the second fixing member 500. The first tube 610 has a predetermined length, and the wire 200 is disposed to penetrate the first tube 610. This first tube 610 may have a smaller width than the second fixing member 500. That is, the second fixing member 500 may have a width greater than the width of the first tube 610 so that it is not inserted into the first tube 610.

Accordingly, when the first tube 610 moves in the direction of the anchor 100, the second fixing member 500 may be pressed in the direction of the anchor 100.

The second tube 620 is such that the anchor 100, the wire 200, the pressing member 300, the first fixing member 400, the second fixing member 500, and the first tube 610 are disposed inside. It is placed. The second tube 620 is provided to place the anchor 100 at the punctured position of the blood vessel 20. For this purpose, the anchor 100 is configured such that the longitudinal direction of the anchor 100 is aligned with the longitudinal direction of the wire 200. It is disposed inside the second tube 620 in a side-by-side state.

The third tube 630 is arranged so that the wire 200, the pressing member 300, the first fixing member 400, the second fixing member 500, and the first tube 610 are disposed inside. This third tube 630 may be placed inside the second tube 620. Additionally, the width of the third tube 630 may be smaller than the thickness of the anchor 100 so that the anchor 100 is not inserted into the third tube 630. In other words, in a state in which the longitudinal direction of the anchor 100 is arranged parallel to the longitudinal direction of the wire 200, the third tube 630 is positioned so that the anchor 100 is not inserted into the inside of the third tube 630. The width may be smaller than the thickness of the anchor 100.

The fourth tube 640 is arranged to cover at least a portion of the outer surface of the second tube 620. This fourth tube 640 protects the second tube 620.

The transmitter 700 is coupled to the fourth tube 640 and supports the hemostatic device 10. This transmitter 700 adjusts the positions of the first tube 610, second tube 620, and third tube 630 included in the hemostasis device 10, so that the anchor 100 is connected to the second tube ( 620) can be adjusted to be discharged to the outside.

Using this hemostasis device 10, the hemostasis device 10 can be inserted into the patient's blood vessel 20 to close the punctured position in the blood vessel 20 and stop the bleeding. At this time, while the anchor 100 is placed within the second tube 620, the end of the second tube 620 may be placed inside the blood vessel 20. And while the third tube 630 is fixed, when the second tube 620 is moved toward the transmitter 700, the anchor 100 may protrude from the end of the second tube 620.

When the anchor 100 protrudes from the second tube 620 inside the blood vessel 20 and the wire 200 is pulled, as shown in FIG. 5, the anchor 100 is rotated to be caught on the blood vessel wall 22. can be placed. And, when the user presses the third tube 630 toward the anchor 100 so that it is in close contact with the second fixing member 500 while an external force is applied to the wire 200 in the direction where the transmitter 700 is located, the second fixing member ( 500) may be pressed toward the anchor 100.

As the second fixing member 500 is pressed toward the anchor 100, the first fixing member 400 can be pressed, so that the first fixing member 400 can press the pressing member 300. Accordingly, the pressing member 300 disposed in the longitudinal direction of the wire 200 may be pressed and folded relative to the wire 200, and as shown in FIG. 6, it may be folded and disposed on the outer surface of the blood vessel wall 22. You can.

As the pressure member 300 is in contact with the outer surface of the blood vessel wall 22 and is overlapped or folded several times to come together, the location where the blood vessel 20 is punctured can be sealed by the anchor 100 and the pressure member 300.

Here, the first fixing member 400 is placed in the skin located outside the blood vessel 20, and the catching protrusion 410 of the first fixing member 400 may be placed in a state where it is caught on the skin. As the first fixing member 400 is disposed within the skin and is fixed so as not to be pushed backward by the catching protrusion 410, the first fixing member 400 can continuously pressurize the pressing member 300.

In addition, as the second fixing member 500 is maintained in close contact with the rear end of the first fixing member 400, it is possible to additionally prevent the position of the first fixing member 400 from moving toward the transmitter 700. there is.

When the compression member 300 is pressed and folded or folded several times on the outer surface of the blood vessel wall 22, the user can remove the third tube 630 from the wire 200, as shown in FIG. 7. Additionally, the hemostasis procedure that blocks the punctured location of the blood vessel 20 can be completed by cutting the wire 200 exposed to the outside of the skin.
