Description

Vascular reinforcement for vascular anastomosis and stapler for vascular anastomosis

[0001] The present invention relates to a vascular reinforcement device for vascular anastomosis and a stapler for vascular anastomosis, and more specifically, to a vascular reinforcement device for vascular anastomosis and a stapler for vascular anastomosis that reinforces the anastomosis site of the aorta so that the anastomosis between the aorta and the artificial blood vessel can be performed more stably.

[0002] Vascular diseases (occlusion, enlargement) are on the rise due to a lack of exercise and the Westernization of dietary habits.

[0003] Surgical methods are adopted to treat such occluded or nearly occluded blood vessels. The surgical method involves cutting out the problematic portion of the blood vessel and replacing the severed parts with artificial blood vessels.

[0004] At this time, when there is a large portion of the blood vessel damaged, a method was disclosed in which an artificial blood vessel is placed in the severed portion of the blood vessel and the existing blood vessel is anastomosed with the artificial blood vessel.

[0005] Figure 1 is a diagram showing the anastomosis of a conventional blood vessel and an artificial blood vessel.

[0006] Referring to FIG. 1, it can be seen that after preparing an artificial blood vessel (2) to be anastomosed to the patient's aorta (1), the end of the artificial blood vessel (2) is brought into contact with the end of the aorta (1), and then anastomosis is performed using a suture (3).

[0007] At this time, it can be seen that reinforcement is performed by placing a predetermined reinforcing piece (4) at each part where the suture (3) is connected in the aorta (1).

[0008] In this case, when replacing a portion of the aorta with an artificial blood vessel, the aorta is already weakened, so even if a reinforcing piece is placed at the point where the suture is connected, placement is not easy, and bleeding or difficulties in anastomosis may occur.

[0009] Published Patent No. 10-2019-0037566 may be cited as an example of prior art for the present invention.

[0010] The present invention aims to solve the above-mentioned problems by providing a vascular reinforcing device and a vascular anastomosis stapler, wherein, when anastomosis is performed between an aorta and an artificial blood vessel to replace a part of the aorta with an artificial blood vessel, reinforcing devices are placed on the inner and outer sides of the end of the aorta to which the artificial blood vessel is anastomotically connected, respectively, to reinforce the tissue of the aorta and maintain its shape, thereby facilitating anastomosis with the artificial blood vessel.

[0011] To achieve the above objective, the present invention provides a vascular anastomosis reinforcing member comprising: a first reinforcing member positioned on the inner side of the blood vessel and having a shape corresponding to the inner shape of the blood vessel; and a second reinforcing member positioned on the outer side of the blood vessel and having a shape corresponding to the outer shape of the blood vessel.

[0012] The first reinforcing member and the second reinforcing member may include a plurality of unit reinforcing members connected in a continuous manner.

[0013] The first reinforcing member and the second reinforcing member may include PTFE (Polytetrafluoroethylene) felt.

[0014] In addition, to achieve the above-mentioned purpose, the present invention may provide a stapler for fixing a vascular anastomosis vascular reinforcing member described in any one of claims 1 to 3 to a blood vessel, comprising: a first operating rod inserted into the inner side of the blood vessel, the end of which contacts the inner circumference of the first reinforcing member; and a second operating rod hinge-connected to the first operating rod, disposed outside the blood vessel, supporting the second reinforcing member, and supplying a connecting means.

[0015] It may further include a first support piece disposed at the end of the first operating rod and corresponding to the inner circumference shape of the first reinforcing member, having a bending groove formed therein, and a second support piece disposed opposite to the first support piece at the end of the second operating rod.

[0016] The above connecting means may be formed in the shape of '∩'.

[0017] The above connecting means has both ends penetrating the first reinforcing member, the blood vessel, and the second reinforcing member, and can fix the first reinforcing member and the second reinforcing member to the blood vessel.

[0018] Bend grooves may be formed on both sides of the upper surface of the first operating rod.

[0019] The present invention, as described above, places reinforcing members on the inner and outer sides of the end of the aorta to which the artificial blood vessel is anastomosis, respectively, to reinforce the tissue of the aorta and maintain its shape, thereby enabling easy anastomosis with the artificial blood vessel.

[0026] The present invention provides a vascular anastomosis reinforcing member for reinforcing a blood vessel to be anastomotic, comprising: a first reinforcing member formed in a shape corresponding to the inner shape of the blood vessel and disposed on the inner side of the blood vessel; and a second reinforcing member formed in a shape corresponding to the outer shape of the blood vessel and disposed on the outer side of the blood vessel.

[0027] Preferred embodiments according to the present invention will be described in detail below with reference to the attached drawings.

[0028] FIG. 2 is a drawing showing the arrangement of a vascular reinforcement for vascular anastomosis according to one embodiment of the present invention.

[0029] Referring to FIG. 2, a vascular reinforcement member (100) for vascular anastomosis according to one embodiment of the present invention includes a first reinforcement member (110) and a second reinforcement member (120).

[0030] The first reinforcing member (110) may be formed by arranging a plurality of unit reinforcing members in a ring shape along the inner side of the end of the aorta.

[0031] Here, the first reinforcing member (110) can be formed by being arranged in a shape corresponding to the inner shape and size of the end of the aorta to be anastomosed.

[0032] The second reinforcing member (120) may be formed by arranging a plurality of unit reinforcing members in a ring shape along the outer side of the end of the aorta. The second reinforcing member (120) may be arranged on the outer side of the end of the aorta to be anastomosed.

[0033] Here, the second reinforcing member (120) can be formed by being arranged in a shape corresponding to the outer shape and size of the end of the aorta to be anastomosed.

[0034] Here, the first reinforcing member (110) and the second reinforcing member (120) may be positioned facing each other with the aorta in between at the end of the aorta to be anastomosed.

[0035] That is, the first reinforcing member (110) may be formed by continuously arranging a plurality of first unit reinforcing members (112) formed in a predetermined arc shape, and the second reinforcing member (120) may be formed by continuously arranging second unit reinforcing members (122) formed in a predetermined arc shape.

[0036] Here, the first reinforcing member (110) and the second reinforcing member (120) may be made of a sheet made of PTFE (Polytetrafluoroethylene).

[0037] When anastomosing the aorta with the artificial blood vessel, the user resects a portion of the aorta (1) for anastomosis with the artificial blood vessel. After the portion of the aorta is resected, an artificial blood vessel (2) connected to the aorta (1) is prepared.

[0038] Afterwards, first and second reinforcing members (110, 120) are placed on the inner and outer sides, respectively, of the end of the aorta to be anastomosed.

[0039] FIG. 3 is a drawing showing an example of the configuration of a stapler for vascular anastomosis according to an embodiment of the present invention, and FIG. 4 is a drawing showing the fixation of the first and second reinforcing members by the stapler for vascular anastomosis according to an embodiment of the present invention. In addition, FIG. 5 is a drawing showing the supply of a connecting means by the stapler for vascular anastomosis according to an embodiment of the present invention.

[0040] Referring to FIGS. 3 to 5, a stapler (200) for vascular anastomosis according to one embodiment of the present invention includes a first operating rod (210) and a second operating rod (220).

[0041] The first operating rod (210) is formed with a predetermined length, and one end is hinge-connected to the second operating rod (220) described later, and the other end can be inserted into the aorta (1) to be anastomosed.

[0042] The other end of the first operating rod (210) can support the inside of the first reinforcing member (110) after being inserted into the aorta (1).

[0043] Here, a first support piece (212) having a shape corresponding to the inner circumference shape of the first reinforcing member (110) may be disposed at the other end of the first operating rod (210) that contacts the inner circumference of the first reinforcing member (110).

[0044] On both sides of one side of the first support piece (212), a bending groove (214) for bending the end of the connecting means (240) described later may be formed.

[0045] When the aorta (1) and the artificial blood vessel (2) are anastomosed, the first support piece (212) can be in contact with the inner circumference of the first reinforcing member (110) and support the first reinforcing member (110).

[0046] The second operating rod (220) is formed with a predetermined length and can be hinge-connected to one end of the first operating rod (210).

[0047] The other end of the second operating rod (220) may be positioned on the outside of the aorta (1) to be anastomosed. At this time, the other end of the second operating rod (220) may come into contact with the outer circumference of the second reinforcing member (120) positioned on the outside end of the aorta (1).

[0048] Here, a second support piece (222) having a shape corresponding to the shape of the outer circumference of the second reinforcing member (120) may be disposed at the other end of the second operating rod (220) that contacts the outer circumference of the second reinforcing member (120).

[0049] When the aorta (1) and the artificial blood vessel (2) are anastomosed, the second support piece (222) can be in contact with the outer circumference of the second reinforcing member (120) and support the second reinforcing member (120).

[0050] It can be confirmed by FIG. 4 that the first reinforcing member (110) and the second reinforcing member (120) are respectively placed on the inner and outer sides of the aorta (1).

[0051] Meanwhile, a connecting means (240) described later can be supplied through the other end of the second operating rod (220).

[0052] The supply of the connecting means (240) can be confirmed by FIG. 5. In FIG. 5, to avoid complexity of the drawing, the illustration of the aorta (1) and the first and second reinforcing members (110, 120) is omitted.

[0053] The connecting means (240) penetrates the first and second reinforcing members (110, 120) positioned on the inner and outer sides of the end of the aorta (1) and connects the first and second reinforcing members (110, 120) to each other so that the reinforcement of the aorta (1) by the first and second reinforcing members (110, 120) is maintained.

[0054] The connecting means (240) can be formed in the shape of '∩'.

[0055] The connecting means (240) may be made of a specific metal. Here, any metal that can maintain the first and second reinforcing members (110, 120) on the aorta (1) and does not adversely affect the patient, such as stainless steel, may be used.

[0056] The connecting means (240) can be supplied one by one when the user applies pressure at the other end of the second operating rod (220).

[0057] After the end of the connecting means (240) passes through the second reinforcing member (120), the aorta (1), and the first reinforcing member (110) in sequence, it can be bent into a circular shape inside the bending groove (214) as shown in FIG. 6.

[0058] Accordingly, when the user operates the stapler (200), the connecting means (240) is supplied, and the first and second reinforcing members (110, 120) can be fixed to the end of the aorta (1). At this time, the user moves the stapler (200) along the end of the aorta (1) and supplies the connecting means (240) in multiple ways so that the first and second reinforcing members (110, 120) are fixed to the end of the aorta (1).

[0059] Next, the step involves connecting the aorta and the artificial blood vessel using sutures to perform anastomosis.

[0060] When connecting the aorta and the artificial blood vessel, the user passes the suture through the first and second reinforcing members (110, 120), connects it to the artificial blood vessel, and performs anastomosis between the aorta and the artificial blood vessel.

[0061] The present invention, configured as described above, places reinforcing members on the inner and outer sides of the end of the aorta to which the artificial blood vessel is anastomosis, respectively, to reinforce the tissue of the aorta and maintain its shape, thereby enabling easy anastomosis with the artificial blood vessel.

[0062] The present invention has been described with reference to the embodiments illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims.
