In the embodiment illustrated in FIG. 4A through FIG. 4G, an auxiliary anastomosis device 1000 comprises a pipe portion 1010 and a movement portion 1020. The movement portion 1020 has a first joining device movement portion 1021 and a second joining device movement portion 1022. The movement portion 1020 is connected to the pipe portion 1010 and is movable relative to the pipe portion 1010. Preferably, the movement portion 1020 is at least partially disposed in (or fitted to) the pipe portion 1010 and is movable relative to the pipe portion 1010 in a first operation direction 2910 or a second operation direction 2920.

[0136] Preferably, the first joining device movement portion 1021 is configured to connect to a first tubular organ joining device 9010, and the second joining device movement portion 1022 is configured to connect to a second tubular organ joining device 9020.

In other words, the first tubular organ joining device 9010 is connected to the first notch portion 1025 of the first joining device movement portion 1021 , and the second tubular organ joining device 9020 is connected to the second notch portion 1026 of the second joining device movement portion 1022. It is noteworthy that the tubular organ joining devices can also be referred to as anastomosis devices. For example, the first tubular organ joining device is also known as a first anastomosis device, and the second tubular organ joining device is also known as a second anastomosis device. It should be understood that a tubular organ joining device is also known as an anastomosis device. For example, a first tubular organ joining device is also known as a first anastomosis device, and a second tubular organ joining device is also known as a second anastomosis device.

[0137] Preferably, the first joining device movement portion 1021 is disposed on a first side 1010A of the movement portion 1020 and has a first arcuate portion1023, whereas the second joining device movement portion 1022 is disposed on a second side 1010B of the movement portion 1020 and has a second arcuate portion1024.

A first stretchingwidth 9110 between the first movement front-end portion 1021 A and the second movement front-end portion 1022A is greater than a second stretching width 9120 between the first movement rear-end portion 1021 B and the second movement rear-end portion 1022B. The first stretching width 9110 is greater than the diameter of the pipe portion 1010. Thus, the first joining device movement portion 1021 and the second joining device movement portion 1022 gradually move farther apart from each other while the movement portion 1020 is moving relative to the pipe portion 1010 in the first operation direction 2910. The first joining device movement portion1021 and the second joining device movement portion 1022 gradually approach each other while the movement portion 1020 is moving relative to the pipe portion 1010 in the second operation direction 2920. A pipe end portion 1014 of the pipe portion 1010 comes into contact with (for example, abuts against) the first arcuate portion 1023 and the second arcuate portion 1024 to allow the first movement frontend portion 1021A of the first joining device movement portion 1021 and the second movement front-end portion 1022A of the second joining device movement portion1022 to gradually move farther apart from each other while the movement portion 1020 is moving relative to the pipe portion 1010 in the first operation direction 2910. The pipe end portion 1014 of the pipe portion 1010 comes into contact with (for example, abuts against) the first arcuate portion 1023 and the second arcuate portion 1024 to allow the first movement front-end portion 1021A of the first joining device movement portion 1021 and the second movement front-end portion 1022A of the second joining device movement portion 1022 to gradually approach each other while the movement portion 1020 is moving relative to the pipe portion 1010 in the second operation direction 2920.

When the movement portion 1020 is in the closed state, the first movement front-end portion 1021 A of the first joining device movement portion 1021 and the second movement front-end portion 1022A of the second joining device movement portion 1022 are drawn closer to each other or even come into contact with each other. With the movement portion 1020 being in the closed state, the first tubular organ joining device 9010 disposed / mounted on the first joining device movement portion 1021 and the second tubular organ joining device 9020 disposed / mounted on the second joining device movement portion 1022 are joined, allowing a first tubular organ and the second tubular organ to be joined / anastomosed to each other through the first tubular organ joining device 9010 and the second tubular organ joining device 9020.

[0139] Preferably, the first joining device movement portion 1021 has a first frontend inner surface 1027, and the second joining device movement portion 1022 has a second front-end inner surface 1028. The first front-end inner surface 1027 and the second front-end inner surface 1028 gradually align in the same direction while the movement portion 1020 is moving relative to the pipe portion 1010 in the first operation direction 2910 (at this point in time, the movement portion 1020 gradually enters a protruded state.) Thus, the user can easily carry out subsequent operation processes, for example, a process of connecting the first tubular organ end portion and the first tubular organ joining device 9010, and a process of connecting the second tubular organ end portion and the second tubular organ joining device 9020.The first front-end inner surface 1027 and the second front-end inner surface 1028 gradually turn toward each other while the movement portion 1020 is moving relative to the pipe portion 1010 in the second operation direction 2920 (at this point in time, the movement portion 1020 gradually enters a recycled state.) Thus, the aforesaid subsequent operation processes can be followed by a process of connecting the first tubular organ joining device 9010 and the second tubular organ joining device 9020 (or, in other words, a process of anastomosing two tubular organs to each other using the first tubular organ joining device 9010 and the second tubular organ joining device 9020).

[0140] Preferably, the first front-end inner surface 1027 of the first joining device movement portion 1021 defines a first normal direction 9130, and the second frontend inner surface 1028 of the second joining device movement portion 1022 defines a second normal direction 9140. The angle between the first normal direction 9130 and the second normal direction 9140 gradually decreases (or, in other words, with the angle between the first normal direction 9130 and the second normal direction 9140 gradually approaching 90 degrees) while the movement portion 1020 is moving relative to the pipe portion 1010 in the first operation direction 2910 (with the movement portion 1020 gradually entering a protruded state at this point in time). Thus, the user can easily carry out subsequent operation processes, for example, a process of connecting the first tubular organ end portion and the first tubular organ joining device 9010 and a process of connecting the second tubular organ end portion and the second tubular organ joining device 9020. The angle between the first normal direction 9130 and the second normal direction 9140 gradually increases (or, in other words, with the angle between the first normal direction 9130 and the second normal direction 9140 gradually approaching 180 degrees) while the movement portion 1020 is moving relative to the pipe portion 1010 in the secondoperation direction 2920 (with the movement portion 1020 gradually entering a recycled state at the same time). Thus, the user can carry out a process of connecting the first tubular organ joining device 9010 and the second tubular organ joining device 9020 (or, in other words, a process of anastomosing two tubular organs to each other using the first tubular organ joining device 9010 and the second tubular organ joining device 9020).

[0141] Preferably, the first arcuate portion 1023 and the second arcuate portion 1024 are arcuate portions which are helical in shape (for example, slightly helical in shape). While the movement portion 1020 is moving relative to the pipe portion 1010 in the first operation direction 2910, the pipe end portion 1014 of the pipe portion 1010 comes into contact with (for example, abuts against) the first arcuate portion 1023 and the second arcuate portion 1024, allowing the angle between the first normal direction 9130 and the second normal direction 9140 to gradually decrease (or, in other words, with the angle between the first normal direction 9130 and the second normal direction 9140 gradually approaching 90 degrees). While the movement portion 1020 is moving relative to the pipe portion 1010 in the second operation direction 2920, the pipe end portion 1014 of the pipe portion 1010 comes into contact with (for example, abuts against) the first arcuate portion 1023 and the second arcuate portion 1024, allowing the angle between the first normal direction 9130 and the second normal direction 9140 to gradually increase (or, in other words, with the angle between the first normal direction 9130 and the second normal direction 9140 gradually approaching 180 degrees).

[0142] Preferably, the pipe portion 1010 has an operation groove 1016, and the movement portion 1020 has an operation portion 1029. The operation portion 1029 extends and passes through the operation groove 1016. Thus, the user controls the movement portion 1020 using the operation portion 1029, allowing the movementportion 1020 to move relative to the pipe portion 1010. Preferably, a groove extension direction 1017 of the operation groove 1016 is substantially parallel to the first operation direction 2910 and the second operation direction 2920.

[0143] Preferably, the auxiliary anastomosis device 1000 further comprises a movable spring portion 1030. The movable spring portion 1030 is connected to (for example, comes into contact with, but the disclosure is not limited thereto) the pipe portion 1010 and the movement portion 1020. The movable spring portion 1030 applies a force to the movement portion 1020, allowing the movement portion 1020 to enter a recycled state or a protruded state. In a specific embodiment, the movable spring portion 1030 is aligned with the first operation direction 2910, with a force applied to the movement portion 1020, allowing the movement portion 1020 to remain in a protruded state. At this point in time, the first joining device movement portion 1021 and the second joining device movement portion 1022 are significantly exposed from the pipe portion 1010, whereas a first overall width of the first movement front-end portion 1021 A and the second movement front-end portion 1022A is greater than a second overall width of the first movement rear-end portion 1021 B and the second movement rear-end portion 1022B. In another specific embodiment, the movable spring portion 1030 is aligned with the second operation direction 2920, and a force is applied to the movement portion 1020, allowing the movement portion 1020 to remain in the recycled state.

[0144] Preferably, the pipe portion 1010 has an auxiliary removal component 1012. The auxiliary removal component 1012 is penetrable by a portion of thetubular organ widening device (to be described later). Thus, after the first tubular organ end portion and the second tubular organ end portion have been joined, the user removes the tubular organ widening device from a tubular organ using an auxiliary removal component 1012. In a specific embodiment, an auxiliary removal component 1012 is penetrable by a first extending segment of a first tubular organ widening device and a second extending segment of the second tubular organ widening device as shown in FIG. 9. It is noteworthy that the tubular organ widening device of the disclosure is not restrictive of the embodiment illustrated in FIG. 9 but may be replaced by any other tubular organ widening device provided in any other form as needed.

The movement portion 220 is connected to the pipe portion 210. The movement portion 220 is configured to be movable relative to the pipe portion 210. The openingand closing mechanism 223 is disposed on the movement portion 220. The movement portion 220 enters the open state (FIG. 5A shows the movement portion 220 in the open state) or the closed state (FIG. 5B shows the movement portion 220 in the closed state) through the opening and closing mechanism 223. When the movement portion 220 is in the open state, the first movement front-end portion of the first joining device movement portion 221 and the second movement frontend portion of the second joining device movement portion 222 separate from each other and move apart. When the movement portion 220 is in the closed state, the first movement front-end portion of the first joining device movement portion 221 and the second movement front-end portion of the second joining device movement portion 222 approach each other or even come into contact with each other.

The second guide portion 223D is at least partially disposed in the second guide slot 223F. Thus, the second guide portion 223D is movable in the second guide slot 223F in the extension direction to cause one end of the first support 223A to move in the second guide slot 223F in the extension direction. The auxiliary opening portion 223H is connected between the first joining device movement portion 221 and the second joining device movement portion 222 and configured to apply a driving force to the first joining device movement portion 221 and the second joining device movement portion 222 and thereby ensure that the opening and closing mechanism 223 can cause the movement portion 220 to remain in the openstate while the movement portion 220 (or the opening and closing mechanism 223 of the movement portion 220) is moving toward the outside of the pipe portion 210.

While the movement portion 220 is moving relative to the pipe portion 1010 in the second operation direction 914, the opening and closing mechanism 223 of the movement portion 220 gradually moves toward the inside of the pipe portion 210, and the pipe end portion of the pipe portion 210 comes into contact with (for example, abuts against) the first inclined surface 221A and the second inclined surface 222A, allowing the movement portion 220 to enter the closed state gradually. It is noteworthy that the first inclined surface 221 A and the second inclined surface 222A can be regarded as a portion of the opening and closing mechanism 223, that is, the opening and closing mechanism 223 comprises the first inclined surface 221A and the second inclined surface 222A. Preferably, the open width 920 of the movement portion 220 is greater than the diameter of the pipe portion 210 while the movement portion 220 is in the open state.

With the second tubular organ end portion being widened by the second widening portion 666, the first front-end portion 666A is located inside the second tubular organ, and the second rear-end portion 666B is located at the second tubular organ end portion of the second tubular organ. Preferably, the diameter (also known as a second diameter) of the second widening portion 666 gradually decreases from the second rear-end portion 666B to the second front-end portion 666A. Preferably, the second front-end portion 666A is connected to the second extending segment 662. Thus, the second tubular organ widening device 660 is moved from the second front-end portion 666A and gradually removed from the second tubular organ while the second extending segment 662 is being pulled to remove the second tubular organ widening device 660 from the second tubular organ. In doing so, the second tubular organ is protected against damage otherwisecaused by the second tubular organ widening device 660. In a specific embodiment, an anastomosis set of the disclosure comprises an auxiliary widening component such that the user inserts the first widening portion 656 into the first tubular organ end portion using the auxiliary widening component, allowing the first widening portion 656 to widen the first tubular organ end portion. The user further inserts the second widening portion 666 into the second tubular organ end portion using the auxiliary widening component, allowing the second widening portion 666 to widen the second tubular organ end portion. Preferably, the auxiliary widening component inserts a widening portion into a tubular organ end portion using the auxiliary frontend portion. The auxiliary front-end portion is conical or substantially conical (allowing the diameter of the auxiliary front-end portion to decrease toward the front end.)

The clamp portion 1051 is movable relative to the clamp sleeve 1056. The clamp control portion 1052 pushes the clamp portion 1051 while the user is pressing the clamp control portion 1052, allowing the front end of the clamp portion 1051 to protrude from the clamp sleeve 1056 and thereby cause the clamp portion 1051 to enter the open state. The control spring 1053 pulls the clamp control portion 1052 as soon as the user releases the clamp control portion 1052 (i.e. , release the pressing force on the clamp control portion 1052). At this point in time, the clamp control portion 1052 triggers the clamp portion 1051 towork, allowing the front end of the clamp portion 1051 to advance in the sleeve extension direction, at least partially move into the clamp sleeve 1056, and thereby cause the front end of the clamp portion 1051 to press against the wall of the clamp sleeve 1056 and gradually enter the clamped state.

After that, as shown in FIG. 14B, the user allows the front end of the clamp portion 1051 of the clamp device 1150 to penetrate the first inner hole of the first tubular organ joining device 1120, and then the control clamp device 1150 allows the clamp portion 1051 to clamp the tubular organ end portion of the first tubular organ 2100. As shown in FIG. 14C, the user controls the clamp device 1150 to pull the first tubular organ 2100, and controls the first tubular organ 2100 to penetrate the first inner hole of the firsttubular organ joining device 1120. Then, the user allows the tubular organ end portion of the first tubular organ 2100 to be connected to (for example, to come into contact with or be fixed to) the first tubular organ joining device 1120. The way of fixing the tubular organ end portion of the first tubular organ 2100 to the first tubular organ joining device 1120 is described later.

[0169] Preferably, the tubular organ widening device is conducive to connecting the tubular organ end portion of the first tubular organ 2100 to the first tubular organ joining device 1120, and related details thereof are described before and thus are not reiterated once again for the sake of brevity. It is noteworthy that the user allows the tubular organ end portion of the second tubular organ 2200 to be connected to (for example, to come into contact with or be fixed to) the second tubular organ joining device 1130 in the aforesaid manner. It is noteworthy that FIG. 14A through FIG. 14C serve illustrative purposes only. In practice, the clamp device is not necessarily configured to function solely as the clamp devices shown in FIG. 13A and FIG. 13B, but may function as a medical clamp device capable of clamping as needed to substitute for the clamp device 1150 shown in FIG. 14A through FIG. 14C.

[0170] Refer to FIG. 15A through FIG. 15E. FIG. 15A is a schematic view of an end portion fixation device in a closed state (also known as a fixation device closed state) according to a specific embodiment of the disclosure. FIG. 15B is a schematic view of the end portion fixation device in an open state (also known as a fixation device open state) according to a specific embodiment of the disclosure. FIG. 15C through FIG. 15E are schematic views of using the end portion fixation device to fix the tubular organs to the tubular organ joining devices according to a specific embodiment of the disclosure. In the embodiment illustrated in FIG. 15A through FIG. 15E, an end portion fixation device 1200 comprises a fixation movementportion 1210, fixation pipe portion 1220, and fixation control portion 1230. The fixation movement portion 1210 is at least partially disposed in the fixation pipe portion 1220, and is movable relative to the fixation pipe portion 1220. The fixation control portion 1230 is connected to at least one of the fixation movement portion 1210 and the fixation pipe portion 1220, and is movable relative to the fixation pipe portion 1220. The fixation control portion 1230 drives (for example, pushes or pulls, but the disclosure is not limited thereto) the fixation movement portion 1210, allowing the fixation movement portion 1210 to move relative to the fixation pipe portion 1220 and thereby enter the closed state or open state.

[0171] Preferably, the end portion fixation device 1200 comprises a spring portion 1240 and / or fixation gripping portions 1262, 1264. The fixation gripping portions 1262, 1264 are connected to at least one of the fixation pipe portion 1220 and the spring portion 1240. The fixation gripping portions 1262, 1264 allow easy gripping by the user. The spring portion 1240 is connected to the fixation control portion 1230. The fixation control portion 1230 triggers the movement of (for example, pushes) the fixation movement portion 1210 while the user is pressing the fixation control portion 1230, allowing the fixation movement portion 1210 to move relative to the fixation pipe portion 1220 in direction 960, and thereby allowing the fixation movement portion 1210 to enter the open state (shown in FIG. 15B). The spring portion 1240 triggers the movement of (for example, pulls) the fixation control portion 1230 as soon as the user releases the pressing force on the fixation control portion 1230, allowing the fixation control portion 1230 to trigger the movement of (for example, pull) the fixation movement portion 1210 and thereby cause the fixation movement portion 1210 to move relative to the fixation pipe portion 1220 in direction 950. Therefore, the fixation movement portion 1210 enters the closed state (shown in FIG. 15A). Preferably, regardless of whether the fixation movementportion 1210 is in the open or closed state, the front end of the fixation movement portion 1210 is always at least partially exposed from the fixation pipe portion 1220. Preferably, directions 950, 960 are parallel to the extension direction of the fixation pipe portion 1220, whereas direction 950 and direction 960 are opposite to each other. In a specific embodiment, an anastomosis set comprises the end portion fixation device 1200.

[0172] Preferably, the fixation movement portion 1210 comprises a first movement portion 1211 and a second movement portion 1212. The first movement portion 1211 has a first fixation inclined surface 1211A and an auxiliary fixation portion 1211 B. The second movement portion 1212 has a second fixation inclined surface 1212A and a slot portion 1212B. The auxiliary fixation portion 1211 B is disposed at the front end of the first movement portion 1211. The slot portion 1212B is disposed at the front end of the second movement portion 1212. Preferably, both the first fixation inclined surface 1211A of the first movement portion 1211 and the second fixation inclined surface 1212A of the second movement portion 1212 abut against the front end of the wall of the fixation pipe portion 1220. Thus, the wall of the pipe portion 1220 applies an external force to the first fixation inclined surface 1211A and the second fixation inclined surface 1212A while the fixation movement portion 1210 is moving relative to the fixation pipe portion 1220, allowing the fixation movement portion 1210 to enter the open state or the closed state. Preferably, the auxiliary fixation portion 1211 B of the first movement portion 1211 at least partially penetrates the slot portion 1212B of the second movement portion 1212 while the fixation movement portion 1210 is in the closed state. Preferably, the auxiliary fixation portion 1211 B has a first end connected to the first movement portion 1211 and a second end opposing the first end. The outer diameter of the auxiliary fixation portion 1211 B gradually decreases from the first end to the second end. Preferably,the auxiliary fixation portion 1211 B is conical. Preferably, the outer diameter of the first end of the auxiliary fixation portion 1211 B is greater than the inner diameter of the first tubular organ 2100, and the outer diameter of the second end of the auxiliary fixation portion 1211 B is less than the inner diameter of the first tubular organ 2100.

[0173] In a specific embodiment, the process flow collectively illustrated in FIG. 15C through FIG. 15E may follow FIG. 14C. The user allows a first tubular organ joining device 1810 to be mounted on the first movement front-end portion of an auxiliary anastomosis device 1900. Then, the user allows the front end of the first tubular organ 2100 to penetrate the first inner hole of the first tubular organ joining device 1810 (as described before and illustrated in FIG. 14A through FIG. 14C). Then, the user allows the fixation movement portion 1210 to enter the open state, and places the first tubular organ 2100 on the slot portion 1212B of the second movement portion 1212. At this point in time, the slot portion 1212B of the second movement portion 1212 faces the rear side of the first joining device movement portion of the auxiliary anastomosis device 1900 (preferably, allowing the slot portion 1212B of the second movement portion 1212 to face the rear side of the first movement front-end portion of the first joining device movement portion at this point in time), and the auxiliary fixation portion 1211 B of the first movement portion 1211 faces the front side of the first joining device movement portion of the auxiliary anastomosis device 1900 (as shown in FIG. 15C). After that, the user presses the fixation control portion 1230 to cause the fixation movement portion 1210 to enter the closed state and cause the front end of the first tubular organ 2100 and the first tubular organ joining device 1810 to be clamped between the first movement portion 1211 and the second movement portion 1212. At this point in time, the front end of the auxiliary fixation portion 1211 B of the first movement portion 1211 enters thefirst tubular organ 2100 from the front end of the first tubular organ 2100, presses against the wall of the first tubular organ 2100, and causes the wall of the first tubular organ 2100 to flip outward (as shown in FIG. 15D). Thus, the wall that has flipped outward can be fixed to the joining needle portions of the first tubular organ joining device 1810. Therefore, the joining needle portions penetrate the wall at the tubular organ end portion of the first tubular organ 2100, as shown in FIG. 15E.

[0174] Referring to FIG. 16, there is shown a schematic view of how to use an anastomosis set according to a specific embodiment of the disclosure. In the embodiment illustrated in FIG. 16, an anastomosis set comprises an auxiliary anastomosis device 1310, first tubular organ joining device 1320, second tubular organ joining device 1330, clamp device 1340, and end portion fixation device 1350. The user allows the first tubular organ joining device 1320 to be mounted on or connected to the first notch portion of the auxiliary anastomosis device 1310, and allows the second tubular organ joining device 1330 to be mounted on or connected to the second notch portion of the auxiliary anastomosis device 1310. Then, the user causes the first tubular organ end portion 2110 of the first tubular organ 2100 to penetrate the first inner hole of the first tubular organ joining device 1320 using the clamp device 1340 (as described in Step A and illustrated in FIG. 16). Next, the user allows the first tubular organ end portion 2110 of the first tubular organ 2100 to be fixed to the first tubular organ joining device 1320 using the end portion fixation device 1350, and allows the second tubular organ end portion of the second tubular organ 2200 to be fixed to the second tubular organ joining device 1330 using the end portion fixation device 1350 (as described in Step A through Step E and illustrated in FIG. 16). Then, the user allows the first tubular organ joining device 1320 and the second tubular organ joining device 1330 to be joined using the auxiliary anastomosis device 1310 (as described in Step F and Step G andillustrated in FIG. 16). Thus, the first tubular organ end portion 2110 of the first tubular organ 2100 and the second tubular organ end portion of the second tubular organ 2200 are joined / anastomosed to each other through the first tubular organ joining device 1320 and the second tubular organ joining device 1330. Preferably, the user allows the auxiliary anastomosis device 1310 to enter the closed state in order for the first tubular organ joining device 1320 and the second tubular organ joining device 1330 to be joined.

[0175] Referring to FIG. 17A and FIG. 17B, there are shown schematic views of how to use the anastomosis set according to a specific embodiment of the disclosure. In the embodiment illustrated in FIG. 17A and FIG. 17B, an anastomosis set comprises an auxiliary anastomosis device 1410, first tubular organ joining device 1420, second tubular organ joining device 1430, clamp device 1440, and end portion fixation device 1450. The user allows the first tubular organ joining device 1420 to be mounted on or connected to the first notch portion of the auxiliary anastomosis device 1410, and allows the second tubular organ joining device 1430 to be mounted on or connected to the second notch portion of the auxiliary anastomosis device 1410. Then, the user allows the first tubular organ end portion 2110 of the first tubular organ 2100 to penetrate the first inner hole of the first tubular organ joining device 1420 using the clamp device 1440 (as described in Step A and Step B and illustrated in FIG. 17A). Then, the user allows the first tubular organ end portion 2110 of the first tubular organ 2100 to be fixed to the first tubular organ joining device 1420 using the end portion fixation device 1450 (as described in Step C and Step D and illustrated in FIG. 17A). Then, the user allows the second tubular organ end portion 2210 of the second tubular organ 2200 to be fixed to the second tubular organ joining device 1430 using the end portion fixation device 1450 (as conclusively described in Step E and illustrated in FIG. 17B). Then, the user allowsthe first tubular organ joining device 1420 and the second tubular organ joining device 1430 to be joined using the auxiliary anastomosis device 1410 (as described in Step F through Step H and illustrated in FIG. 17B). Thus, the first tubular organ end portion 2110 of the first tubular organ 2100 and the second tubular organ end portion 2210 of the second tubular organ 2200 are joined / anastomosed to each other using the first tubular organ joining device 1420 and the second tubular organ joining device 1430. Preferably, the user allows the auxiliary anastomosis device 1410 to enter the closed state in order for the first tubular organ joining device 1420 and the second tubular organ joining device 1430 to be joined.

[0176] Referring to FIG. 18A and FIG. 18B, there are shown a tubular organ joining device according to a specific embodiment of the disclosure. In the embodiment illustrated in FIG. 18A and FIG. 18B, a front-end joining portion 1510 of a tubular organ joining device 1500 has a plurality of communication holes. The front-end joining portion 1510 is also known as a joining needle channel portion. For example, the front-end joining portion 1510 has communication holes 1512, 1513, 1514, and 1515. The joining needle portions of rear-end joining portions 1520 of the tubular organ joining device 1500 pass through the plurality of communication holes of the front-end joining portion 1510 respectively. For example, joining needle portion 1522 of the rear-end joining portions 1520 pass through the communication hole 1512 of the front-end joining portion 1510, and joining needle portion 1524 of the rear-end joining portions 1520 pass through the communication hole 1514 of the front-end joining portion 1510. Preferably, the front-end joining portion 1510 is first front-end joining portion, the rear-end joining portions 1520 is first rear-end joining portions, the communication holes 1512, 1513, 1514, and 1515 are first communication holes, the joining needle portions 1522, 1524 are first joining needle portions. Preferably, when the first tubular organ joining device (also known asfirst anastomosis device) and the second tubular organ joining device (also known as second anastomosis device) are connected to each other, each of the communication holes 1512, 1514 is penetrated by one of the first joining needle portions respectively (for example, joining needle portion 1522 of the rear-end joining portions 1520 penetrate the communication hole 1512 of the front-end joining portion 1510, and joining needle portion 1524 of the rear-end joining portions 1520 penetrate the communication hole 1514 of the front-end joining portion 1510), and each of the communication holes 1513, 1515 is penetrated by one of the second joining needle portions respectively. Preferably, each of the first communication holes can be penetrated by only one of the first joining needle portions or one of the second joining needle portion at a time, and each of the second communication holes can be penetrated by only one of the first joining needle portions or one of the second joining needle portion at a time.

[0177] Preferably, each of the joining needle portions has a buffer portion (also known as a protrusion portion). For example, each of the joining needle portions 1524 has a buffer portion 1524A that protrudes outward slightly. Each of the communication holes has one or more buffer receiving portions (also known as receiving groove portions. For example, the communication hole 1514 has buffer receiving portions 1514A, 1514B, and 1514C. Thus, friction between the buffer portion and each of the buffer receiving portions prevents each of the front-end joining portions 1510 from being coupled to a corresponding one of the rear-end joining portions 1520 unexpectedly (for example, when the front-end joining portions 1510 or the rear-end joining portions 1520 have not yet been placed in the correct positions but are subjected to unexpected thrust). In the course of connecting the tubular organ joining device 1500 to the tubular organ end portion, it is also feasible to use the friction between the buffer portion and each of the bufferreceiving portions to ensure that the front-end joining portions 1510 and the rear- end joining portions 1520 will cause the rear-end joining portions 1520 to move relative to the front-end joining portions 1510 only if the tubular organ end portion folds in front of the joining needle portions and thereby cause the joining needle portions to penetrate the communication holes and the folded tubular organ end portion. Preferably, the buffer receiving portions of the communication holes are trenches or indentations. Preferably, the magnitude of the friction between the buffer portion and each of the buffer receiving portions is controlled according to the size, shape, depth, and / or number of the buffer receiving portions.

[0178] Referring to FIG. 19, there is shown a schematic view of fixing a tubular organ joining device to a tubular organ end portion according to a specific embodiment of the disclosure. In the embodiment illustrated in FIG. 19, the user (for example, healthcare professionals) allows a tubular organ end portion 2310 of a tubular organ 2300 to penetrate inner holes of a front-end joining portion 1610 and a rear-end joining portion 1620 (see Step A).
