Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to Figures 1 to 8, the connection member for vascular replacement surgery and the device for vascular replacement surgery according to the embodiment of the present invention will be described in detail as follows.

1 and 2 are a perspective view and a cross-sectional view of the connecting member 100 for vascular replacement surgery according to an embodiment of the present invention.

The connection member 100 includes a blood flow pipe 101 coupled to the blood vessel 1 and an extension pipe 102 extending from one side of the blood flow pipe 101.

At this time, the connection member 100 is preferably composed of an assembly member of the upper 103 and lower 104 that can be separated and coupled along the axial surface. The upper part 103 and the lower part 104 each have a semicircular cross section, and preferably, one side of the upper blood flow piece 103A and one side of the lower blood flow piece 104A correspond to a hinge structure or a collapsible connector structure. Upon joining, the overall shape is formed integrally with the T-shaped tube. The blood vessel 1 is inserted into the lower blood piece 104A of the connection member 100, and the tube 110 is inserted into the lower extension piece 104B so that the direction of the blood vessel cutting knife 111 faces the blood flow tube 101. Insert Thereafter, the upper part 103 of the connection member 100 is covered and the fixing nut 130 is tightened to embed the blood vessel 1 in the connection member 100.

The moving range of the tube 110 is limited by the stopper 112 and the recess 109. However, since the tube 110 is not limited to rotation, the incision may be increased by rotating the tube 110 by 90 degrees to increase the blood flow of the tube 110.

The sealing of the tube 110 and the extension tube 102 may be sealed by installing an O-ring or the like.

The expandable O-ring 105 installed in the blood flow pipe 101 of the connection member 100 expands when fluid pressure is applied to seal the gap between the blood vessel 1 and the blood flow pipe 101 of the connection member 100. There is no blood leaking from the blood flow pipe 101 of the member 100 to the outside. Blood vessels vary in size depending on their type. Therefore, it is preferable to use the inflatable o-ring 105 to expand when pressure is applied, such as a balloon. The sealing effect may be enhanced by the fluid injection, but may be such that no blood leaks from the blood flow pipe 101 to the outside without fluid injection. In addition, it is not necessary to use the inflatable O-ring 105, it is also possible to use a general O-ring to prevent blood leakage.

The fluid injection line 106 is installed along the axial surface of the top 103 and the bottom 104 of the connection member 100. The fluid injection line 106 is connected to the inflatable o-ring 105 in the form of a tube. A fluid inlet 107 for injecting a fluid is provided at the tip of the fluid inlet line 106 exposed outside the extension tube 102. Fluid injection is possible through the fluid inlet 107 and the one end is blocked so that the air injected through the fluid inlet 107 does not leak to the outside. In addition, the fluid injection line 106 fills the gap between the upper portion 103 and the lower portion 104 of the connecting member 100 to seal the blood so as not to leak outside the connecting member 100.

3 to 6 are a perspective view and a cross-sectional view of the connecting member for vascular replacement surgery according to another embodiment of the present invention.

Like reference numerals in the drawings shown above indicate the same members having the same function. However, the fluid injection line 106 connected to the inflatable o-ring 105 is exposed out of the blood flow pipe 101. The fluid injection line 106 may be exposed through the end of the blood vessel 101 (see FIGS. 3 and 4) or through the circumferential direction 101 of the blood vessel (see FIGS. 5 and 6). . When a pair of fluid injection lines 106 are exposed through the circumferential direction of the blood flow pipe 101, a fastening portion may be installed in the exposed fluid injection lines 106 to improve the sealing effect. For example, like a cable tie, a protrusion 106a may be formed in one fluid injection line 106 and a locking member 106b may be formed in the other fluid injection line 106. have. The upper and lower portions of the connecting member 100 may be combined to embed the blood vessel 1 in the blood flow pipe 101, and then the fluid injection line 106 may be pulled and combined to improve the sealing effect (FIG. 5 and 6). In addition, even when the fluid injection line 106 is penetrated in the end direction of the blood flow pipe 101, the fastening portion may be installed in the fluid injection line 106 to improve the sealing effect. In addition, even when the general O-ring is used to prevent blood leakage, the expansion O-ring can be installed to improve the sealing effect.

In addition, the sealing member 108 for preventing blood leakage is installed along the axial surface of the connecting member 100. The sealing member 108 may be a seal, for example silicone packing or rubber packing.

7 is a view showing a device for vascular replacement surgery according to an embodiment of the present invention.

The apparatus for vascular replacement surgery according to the present invention comprises a pair of connecting members 100 consisting of a blood vessel 101 coupled to the blood vessel 1 and an extension tube 102 extending from one side of the blood vessel 101. Include. The extension tube 102 is inserted so that the tube 110 attached to the knife 111 for cutting the blood vessel 1 is connected to both ends. The tube 110 is provided as a passage of blood flowing out of the incision site of the blood vessel 1 or flowing into the incision site of the blood vessel 1.

As described above, the connection member 100 is preferably composed of an assembly member of the upper 103 and lower 104 that can be separated and coupled along the axial surface. The upper and lower sections are each formed in a semicircular cross section. Preferably, one side of the upper blood flow piece 103A and one side of the lower blood flow piece 104A correspond to a hinge structure or a collapsible connection structure. It is formed integrally with a T-shaped tube. The blood vessel (101) of the connection member 100 is inserted into the blood vessel (1) and the extension tube (102) after the tube 110 is inserted into the upper and lower by combining the vessel (1).

The tube 110 is attached to both ends of the vascular incision knife 111 is empty inside. One end of the connection member 100 is detached and inserted into the lower extension piece 104B of the connection member 100 in a direction toward the blood vessel 1 with the end portion of the blood vessel incision knife 111 attached thereto. After coupling, the tube 110 is pushed up to allow the blood vessel 1 embedded in the blood flow tube 101 to be cut. The tube is to serve as a passage of blood flowing out of this incision. In addition, the stopper 112 is preferably installed on the tube 110 and the groove 109 corresponding to the stopper 112 is installed on one side of the inner wall of the connection member 100 so that the operator does not excessively ablate the blood vessel. It can be limited so that the shankdong range of the vascular incision knife 111.

The valve 120 is installed left and right on one side of the tube 110. The valve 120 is the air inside the tube 110, that is, the air between the portion where the valve 120 is installed from the portion attached to the angioplasty knife 111 of the tube 110 is the valve ( 120 is discharged out through the air discharge portion 113 installed in the tube 110 positioned between the serves to allow the blood flowing out from the incision site of the blood vessel flows through the tube (110). In addition, it is preferable to install the blood and injection liquid injection unit 114 to facilitate the injection of the medicine and blood required in the patient's body during the operation to the tube (110).

The fixing nut 130 is fixed at the upper part 103 and the lower part 104 of the connecting member 100 so as not to be separated and at the same time as the cut part of the blood vessel 1 by the incision knife 111. The outflowing blood is prevented from leaking outside the connection member 100.

The clamp 140 tightens the blood vessel 1 so that blood does not flow to the target blood vessel 2, and when cutting the blood vessel 2 for exchanging the blood vessel 2, the ablation portion of the blood vessel and the connection member Fix the relative position of the liver. This prevents the ablation site of the target blood vessel from entering into the connection member 100 when the target blood vessel 2 is excised, as if the elastic rubber is broken.

Referring to Figure 8 describes how to use the apparatus for vascular replacement surgery according to an embodiment of the present invention.

The left side of the blood vessel 1 of the target blood vessel 2 is inserted into the lower blood flow piece 104A of the connecting member 100. In addition, the tube 110 is inserted into the lower extension piece 104B in the direction toward the vessel 1 by the vascular incision knife 111 to cover the upper portion 103 of the connecting member 100. Thereafter, the fixing nut 130 is tightened to the extension tube 102 of the connecting member 100 to keep the upper 103 and the lower 104 of the connecting member 100 in a coupled state, and at the same time, to prevent blood leakage. do. In addition to the fixing nut 130, other means such as a ring may be used to couple the connecting member 100 (see S101). The same procedure is applied to the right side of the target blood vessel 2 as described above (see step S101), so that the right blood vessel portion of the target blood vessel 2 is embedded in the other connection member 100, and then the air discharge unit 113. The blood and injection liquid injection unit 114 and the valve 120 are connected.

Next, when the fluid is injected into the fluid inlet 107, the fluid flows through the fluid injection line 106 to expand the expandable o-ring 105 (see S102). Prevents blood flowing out when leaking to the outside of the connection member (100). The same procedure as described above (see S102) is performed on the right side to prevent the blood from leaking to the outside of the right connection member 100 during vascular incision. The fluid injection procedure (see S102) may enhance the sealing effect of the inflatable o-ring 105 or may prevent blood from leaking out of the blood flow pipe 101 without a separate fluid injection.

Next, open the valve 120 on the left side (see S103) to allow the air to be discharged through the air outlet 113, and then push the tube 110 up to cut the vessel part (see S104) at the incision site. At the same time blood flows to the tube 110, the internal air of the tube 110 is discharged through the air discharge unit 113. In the state where the passage is blocked by the valve 120 and air cannot be discharged to the outside, the residual air of the tube 110 is not compressed to a predetermined volume or less, so that a certain amount of blood does not flow out to the vascular incision.

In addition, if the air outlet 113 is not present, the air outlet 113 is required because the left valve 130 is opened to allow the residual air to flow into the blood vessel 1 and adversely affect the health of the patient. . In addition, when the blood or injection liquid injection unit 114 is provided, the blood or injection liquid injection unit 114 through the blood or injection liquid injection unit 114 before performing the step S103 and S104 before performing the steps S103 and S104 It is possible to more reliably prevent the inflow of residual air into the patient's blood vessels. The above-described processes (see S103 to S104) are performed in the same manner to the right side of the tube 110 using the right valve 120 to remove air from the tube 110.

Next, a pair of clamps 140 are mounted on the left and right sides of the target blood vessel 2 (see S105) to prevent blood from passing through the replacement blood vessel 2 and at the same time, the ablation portion of the blood vessel 2 after the ablation and To maintain the relative position between the connecting member 100.

Next, after the target blood vessel 2 is removed, the new blood vessel 3 is connected to the target blood vessel ablation portion of the blood vessel 1 (see S106).

Next, loosen the clamp 140 (see S107), allow the blood to flow along the new blood vessel 3, close the valve (see S108), loosen the fixing nut 130, and then open the left connecting member 100. Peel off the blood vessel (see S109) and suture the incision site by the vascular incision knife 111 attached to the tube 110 (see S110). In this case, most of the blood flows along the vessel 1 having low flow resistance, but a very small amount of blood can flow out of the incision by the pressure. The same procedure as described above (see S109 to S110) is performed on the right side to separate the right connecting member 100 from the blood vessel 1 and suture the vascular incision site.

In addition to the above structure further comprises a fixing means for connecting the pair of connecting members 100 for fixing the relative position between the target vascular resection site during surgery to fix the position between the resection site of the target blood vessel (2) Convenience can be achieved. The fixing means may be any one for fixing a relative position between the ablation sites, and includes, for example, a supporting rod portion formed in a predetermined length, and each end of the rod portion may be coupled to each connection member. .

In the above embodiment, the valve 120, the air discharge unit 113, and the blood and injection liquid injection unit 114 are provided on the tube 110. The tube 110, the valve 120, and the air discharge unit 113 may be manufactured to be separated and combined.

In addition, in the above embodiment, a pair of valves 120 are used, but a person skilled in the art of the present invention may be easily modified and implemented to achieve the object of the present invention by using only one valve.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

According to the present invention as described above, by providing a bypass portion to replace the blood vessels to be cut before excision of the blood vessels to be cut at the time of vascular replacement surgery, there is an effect of preventing the excessive flow of blood, surgery time and patient recovery time.

In addition, according to the present invention as described above, there is also an effect of saving blood, such as the existing blood inventory can be used for other patients transfusion due to the decrease in blood transfusion requirements.
