Description

Technical Field

[0001] The present invention relates to the technical field of blood vessel suturing, and in particular to a suturing and compression device and a blood vessel suturing device set having the same. Background Art

[0002] Clinically, the traditional surgical method for suturing blood vessels is interventional suturing, which uses a vascular suturing device to puncture and suturing in vitro. This method has the following defects:

[0003] 1) The knot is not tied tightly;

[0004] 2) If the wound is large, suturing will take a long time and the risk will increase significantly.

[0005] Of course, after using Progl ide (vascular suture device) to stop bleeding, if the bleeding is not satisfactory, the gasket reinforcement technique can be considered. Usually, the two longer sutures of the four threads of the two Progl ide are selected. Use a needle of appropriate size to pass through the 7.9mm×3mm PTFE square gasket twice. Then pass the above two sutures through the needle through the gasket and pull out to the tail of the needle. Pull out the needle and use surgical forceps to deliver the gasket to the skin puncture site. Use the Progl ide knot pusher or tie a knot to push the gasket down to close the puncture site. Maintain pressure on the first knot for >1 minute and evaluate the bleeding. If it is believed that the gasket has stopped bleeding, remove the guide wire (if it has not been removed before and is still retained); then tie a second knot; continue to tie knots until at least six knots. If the bleeding is still not good, use traction and compression techniques. Wrap a small piece of gauze around the Progl ide closure suture, and the suture can guide the small gauze through the soft tissue to the puncture site. Tighten the four sutures of the two Progl ide closure devices and place them perpendicular to the skin. Use a vascular clamp to fix the sutures at the lowest position outside the skin and apply appropriate tension (the purpose is to fix the gauze and pull the blood vessels and gasket outward). Maintain compression for 5-10 minutes. If there is still blood oozing out, continue compression for about 5 minutes. After assessing absolute hemostasis, remove the gauze and cut the four sutures.

[0006] With the above-mentioned method, the number of suture holes is not effectively reduced, and the implantation of the gasket is more troublesome, and the area compressed by the gasket is also smaller.

[0007] Based on this, it is necessary to develop a suturing and compression device and a vascular suturing device kit having the same to overcome the above technical problems. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a suturing and compression device and a vascular suturing device kit having the same, which effectively overcomes the defects of the prior art.

[0009] The technical solution of the present invention to solve the above technical problems is as follows:

[0010] A suture compression device comprises a compressible pressurizing body, wherein the pressurizing body is provided with a suture thread channel running through both ends thereof, and the pressurizing body can be compressed to a flat shape along the long axis direction of the suture thread channel.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, two suture thread channels are arranged at intervals in the pressurizing body.

[0013] Furthermore, the pressurizing body is a long flexible member.

[0014] Furthermore, the outer contour of the cross section of the pressurizing body is circular.

[0015] Furthermore, the outer contour of the cross section of the pressurizing body is an ellipse.

[0016] Furthermore, the outer contour of the cross section of the pressurized body is a square.

[0017] Furthermore, the outer surface of the pressurized body is provided with a plurality of circles of inwardly concave overlapping extrusion crease lines between its two ends.

[0018] Furthermore, the interior of the pressurized body is hollow, and threading holes are provided at both ends thereof respectively. The threading holes at both ends and the cavity in the middle together form the suture thread channel.

[0019] Furthermore, the pressurized body is formed by weaving chitosan fibers.

[0020] The beneficial effects of the present invention are: the structural design is simple and reasonable, and it can effectively pressurize and stop bleeding at the sutured part of the blood vessel, and the number of suture needles for the wound is greatly reduced, the suture fault tolerance rate is higher, and the operation is faster and safer.

[0021] A vascular suturing device kit is also provided, comprising a suturing and compression device. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] Example 1

[0029] like Figure 1 As shown, the suture compression device of this embodiment includes a compressible pressurizing body 1, in which a suture thread channel 11 passing through both ends is provided. The pressurizing body 1 can be compressed to a flat shape along the long axis direction of the suture thread channel 11.

[0030] The suture compression device of this embodiment is used during surgery in accordance with the traditional surgical method of the existing vascular suture device (Progl ide) in clinical practice. When pressurized hemostasis is required, the suture (indicated by b in the figure) is passed through the suture channel 11 on the pressurized body 1 through the needle (indicated by a in the figure) and pulled out until the needle tail. Pull out the needle, and as the suture is pulled, the entire pressurized body 1 is passed through the skin puncture site and sent to the suture site of the blood vessel (indicated by c in the figure) with the suture. Then, the Progl ide knot pusher is used to push and compress the gasket pressurized body 1 toward the suture site, so that the pressurized body 1 is deformed, the compression stroke is flat (indicated by D in the figure), and the cross-sectional area is increased, and a large range of coverage and compression is applied to the suture site, which can not only maintain the coverage and compression of the needle eye, but also compress and block the remaining suture sites, and play a role in hemostasis. During the operation, the disadvantages of the traditional need for multiple needle sutures are improved. Small wounds can be sutured with one needle, and slightly larger wounds can also effectively reduce the needle eyes and suture sites generated by the traditional suture method. At the same time, it has a better pressurized hemostasis effect. In addition, the overall method is simpler and faster than the traditional gasket insertion method. That is to say, the entire suture compression device has a simple and reasonable structural design, can effectively pressurize and stop bleeding at the suture site of the blood vessel, and greatly reduce the number of wound suture needles, the suture fault tolerance rate is higher, and the operation is faster and safer.

[0031] In this embodiment, two suture thread channels 11 are arranged at intervals in the pressurizing body 1 .

[0032] As a preferred embodiment, the pressurizing body 1 is a long flexible member.

[0033] In the above implementation scheme, the pressurizing body 1 is reasonably designed, and is initially in the shape of a long strip, which is put outside the suture and can reach the target wound site along the suture. Then, by squeezing the pressurizing body 1 in the long axis direction, it can be effectively flattened (with an increased area) to apply pressure to the suture site to stop bleeding.

[0034] In this embodiment, the outer contour of the cross section of the pressurizing body 1 is circular.

[0035] In this embodiment, the outer contour of the cross section of the pressurizing body 1 is an ellipse.

[0036] In this embodiment, the outer contour of the cross section of the pressurizing body 1 is a square.

[0037] As a preferred embodiment, the outer surface of the pressurizing body 1 is provided with a plurality of circles of inwardly concave overlapping extrusion crease lines 12 between its two ends.

[0038] In the above embodiment, the design of the overlapping extrusion crease line 12 makes the pressurized body 1 look like a "bellows"-shaped object from the outside. When squeezed, it can be compressed and deformed into a flat shape along the overlapping extrusion crease line 12, thereby increasing the area and achieving a large-scale pressurized hemostasis effect on the suture.

[0039] In this embodiment, the pressurizing body 1 is hollow inside, and threading holes are respectively provided at both ends thereof, and the threading holes at both ends and the cavity in the middle together form the suture thread channel 11. The two ends of the pressurizing body 1 are closed, and only the threading holes are exposed.

[0040] As a preferred embodiment, the pressurizing body 1 is formed by weaving chitosan fibers.

[0041] In the above embodiment, the pressurizing body 1 is woven and formed by chitosan fibers, a conventional material that can promote wound healing. After surgery, it can promote the recovery of the sutured area.
