[0026] Reference Figure 1 A packaging system capable of accommodating artificial blood vessels of various shapes, comprising: First shell 10; A combined receiving cavity 20 is disposed on the surface of the first housing 10; The combined receiving cavity 20 includes a first receiving groove 21 and a branch receiving groove 22, and the branch receiving groove 22 is connected to the middle of the first receiving groove 21; The first receiving groove 21 is used to receive the main body of the artificial blood vessel, and the branch receiving groove 22 is used to receive the branch parts of the artificial blood vessel.

[0027] Specifically, the first shell 10 refers to the shell used to accommodate, support, and fix the artificial blood vessel. It is a plate-shaped or groove-shaped support base made of medical-grade rigid or semi-rigid material. It has a recessed cavity structure directly formed on its surface, namely a combined receiving cavity 20, which provides a dedicated receiving space for the artificial blood vessel.

[0028] The combined receiving cavity 20 consists of a first receiving groove 21 and a branch receiving groove 22, which can simultaneously accommodate and fix straight, side-branched, and four-branched artificial blood vessels. The first receiving groove 21 is the main component of the combined receiving cavity 20, with a long, arc-shaped cross-section structure. The arc radius matches the diameter of the main body of the artificial blood vessel to accommodate the main body. The branch receiving groove 22 is the branch component of the combined receiving cavity 20, also with a long, arc-shaped cross-section structure. It connects to the first receiving groove 21 from the middle position at a vertical or inclined angle to accommodate the branch portion of the artificial blood vessel. By dividing the functions of the first receiving groove 21 and the branch receiving groove 22, the artificial blood vessel body and branches are separately received, avoiding mutual interference between different parts. At the same time, by combining the main body receiving and branch receiving in the combined receiving cavity 20, this packaging system can adapt to artificial blood vessels with different branch types, such as straight, side-branched, and four-branched artificial blood vessels, thus improving the applicability of the packaging system. In addition, the fixed angle design of the branch receiving groove 22 can fix the connection angle between the branch and the main body, avoiding repeated stress damage caused by the relative sliding of the artificial blood vessel branches during transportation.

[0029] This application provides a packaging system capable of accommodating artificial blood vessels of various shapes, including: First shell 10; A combined receiving cavity 20 is disposed on the surface of the first housing 10; The combined receiving cavity 20 includes a first receiving groove 21 and a branch receiving groove 22, and the branch receiving groove 22 is connected to the middle of the first receiving groove 21; The first receiving groove 21 is used to receive the main body of the artificial blood vessel, and the branch receiving groove 22 is used to receive the branch parts of the artificial blood vessel.

[0030] By dividing the functions of the first receiving groove 21 and the branch receiving groove 22, the main body and branches of the artificial blood vessel are separately received, avoiding mutual interference between different parts. At the same time, by combining the main body receiving and branch receiving in the combined receiving cavity 20, this packaging system can adapt to artificial blood vessels of different branch types, such as straight, side-branched, and four-branched artificial blood vessels, thus improving the applicability of the packaging system.

[0031] In some implementations, refer to Figure 1 There are two symmetrically arranged branch receiving slots 22. Specifically, it is preferable to set two branch receiving slots 22 because in current clinical applications, bibranched artificial blood vessels are the most mainstream multibranched type, such as the Y-shaped artificial blood vessel commonly used in coronary artery bypass grafting. However, in actual use, the combined receiving cavity 20 formed by the combination of the two branch receiving slots 22 and the first receiving slot 21 can still accommodate straight, lateral bifurcation, and quadrifurcation artificial blood vessels. For example, the main body of the quadrifurcation artificial blood vessel can be accommodated in the first receiving slot 21, and then the four branches of the quadrifurcation artificial blood vessel can be divided into two groups, placed in different branch receiving slots 22 on the left and right respectively. Correspondingly, the width of the branch receiving slot 22 should be sufficient to accommodate two branch tubes.

[0032] When artificial blood vessels are used clinically, medical staff need to quickly confirm whether the shape of the artificial blood vessel matches the patient's lesion. The visual symmetry of the symmetrical branch groove can intuitively indicate the physiological shape of the blood vessel, such as the left branch tube being slightly longer than the right branch tube, thereby improving the operating efficiency of medical staff.

[0033] In addition, most bibranched blood vessels in the human body are distributed in an approximately symmetrical manner. The symmetrical branching groove can maintain the physiological consistency of the artificial blood vessel within the packaging by pre-setting symmetrical angles, avoiding vascular wall wrinkles caused by asymmetrical placement, and ensuring unobstructed blood flow after implantation.

[0034] In some implementations, refer to Figure 1 A dividing boss 30 is provided at the central axis of the branch receiving groove 22, and a space is left between the dividing boss 30 and the two side walls of the branch receiving groove 22 to accommodate the branch portion of the artificial blood vessel. Specifically, the dividing boss 30 is located at the central axis of the branch receiving groove 22, thereby dividing the branch receiving groove 22 into two sub-receiving spaces. The four sub-spaces are centrally symmetrically distributed, so that the symmetrically arranged branch receiving groove 22 can independently place the branch tubing of the four-branched artificial blood vessel. In addition, after the branch blood vessel is placed in the groove, its two sides contact the side walls of the dividing boss 30 and the side walls of the branch receiving groove 22, respectively. The dividing boss 30, through physical blocking, prevents the branch from shifting due to vibration or tilting during transportation.

[0035] In some implementations, refer to Figure 1A groove 40 is provided between the two symmetrically arranged branch receiving grooves 22. The groove 40 communicates with both branch receiving grooves 22, and the depth of the groove 40 is greater than the depth of the branch receiving groove 22. Specifically, the four-branch artificial blood vessel is usually a four-branch structure with three branch vessels in a row and one branch branching out from the side. The three main branch vessels are arranged in parallel, usually corresponding to the brachiocephalic artery, left common carotid artery and left subclavian artery on the aortic arch. The fourth branch is usually located on the side of the main trunk for distal anastomosis or special perfusion needs.

[0036] In this situation, the horizontal placement of the four-branched artificial blood vessel will cause the fourth branch to form a placement surface normal to the other three main branches, resulting in two branches overlapping vertically, which can easily lead to twisting and knotting between these two branches. The groove 40 is located between the two symmetrical branch receiving grooves 22 to specifically accommodate the two overlapping branches, thereby creating a state where they are separated from each other with a certain separation distance, so as to avoid the two overlapping branches twisting and knotting between each other.

[0037] For example, the groove 40 is disposed between the two branch receiving grooves 22, and the shape of the groove 40 is rectangular. The size of the groove 40 extends to the middle part of the main vessel of the four-branched artificial blood vessel, that is, the position where the fourth branch vessel branches off from the side. In this case, the fourth branch vessel is positioned facing the groove 40 and placed in the groove 40. The fourth branch vessel is attached to the bottom of the groove 40 and extends to a sub-receiving space of the branch receiving groove 22, thereby maintaining a separation space between the fourth branch vessel and other main branch vessels that is slightly smaller than the depth of the groove 40. This avoids the fourth branch vessel from spatially interfering with the main branch vessel and becoming entangled on the path extending to the sub-receiving space of the branch receiving groove 22.

[0038] For example, the groove 40 is formed between two symmetrical branch receiving grooves 22, and its shape is designed to be rectangular or circular. Its size does not need to extend to the middle of the main vessel of the four-branched artificial blood vessel, and the depth of the groove 40 is deeper than that of the branch receiving groove 22. Because the fourth branch vessel is often located outside the horizontal plane formed by the three branch vessels, and its projection in the vertical direction is often located between the two branch vessels at the edge, due to its setting position, it is farther away from the branch receiving groove 22. This means that it can only be placed in the sub-receiving space of the branch receiving groove 22 that is closer to it, while the branch vessel on the same side as the fourth branch vessel can only be fixed in the relatively farther sub-receiving space. This causes the fourth branch vessel to easily become entangled with this branch vessel.

[0039] The design of the groove 40 being deeper than the branch receiving groove 22 allows the branch vessels on the same side located in the area covered by the groove 40 to tend to sink with the groove 40. After the branch vessels are embedded in the deeper space of the groove 40, they form a vertical height difference with the fourth branch located in the sub-receiving space of the branch receiving groove 22. Even if the vertical projection of the fourth branch is still between the two edge main branches, the two cannot be attached to the upper and lower walls due to the physical gap in the vertical direction, thus avoiding entanglement between them.

[0040] In some implementations, refer to Figure 1 and Figure 2 A packaging system capable of accommodating artificial blood vessels of various shapes also includes a second housing 50, the shape and size of which match the first housing 10, and a fixing structure is provided on the second housing 50. Specifically, the second housing 50 is made of the same medical-grade material as the first housing 10, and its shape matches the first housing 10, allowing it to be snapped together as a whole.

[0041] The second housing 50 is provided with a fixing structure to securely connect the second housing 50 to the first housing 10, and to add an outer layer of protection on the basis of the first housing 10 to further resist external squeezing, collision and impact during transportation and storage, so as to avoid deformation of the artificial blood vessel wall or damage to the branch connection.

[0042] After the second housing 50 covers the first housing 10, it can exert a slight holding force on the artificial blood vessel in the cavity from above through the shape setting of the fixed structure, thereby preventing the blood vessel from moving in the vertical direction and further fixing the overall shape of the blood vessel.

[0043] For example, the fixing structure includes a snap-fit ​​assembly evenly distributed along the edge of the second housing 50. The snap-fit ​​can be pressed and moved towards the inside of the housing, corresponding to a snap-fit ​​groove preset on the edge of the first housing 10. Pressing the snap-fit ​​can embed it into the snap-fit ​​groove of the first housing 10, realizing a quick and stable connection between the two housings and resisting the risk of separation during transportation.

[0044] For example, the fixing structure includes multiple sets of elastic protrusions provided on the inner surface of the second housing 50. The protrusions are raised and have a certain deformation capability, corresponding to the positioning holes on the surface of the first housing 10. When fastened, the elastic protrusions are embedded in the positioning holes, which not only achieves precise alignment of the two housings, but also buffers external pressure through the elastic deformation of the protrusions. At the same time, the height design of the protrusions can help the second housing 50 and the first housing 10 maintain a reasonable distance, forming a gentle holding force on the blood vessel from above, and fixing the shape of the blood vessel.

[0045] In some implementations, refer to Figure 1 and Figure 2 The fixed structure includes: The first structure 61 is disposed on the second housing 50 at a position corresponding to the first housing 10, and includes a first connecting boss 611 and a first connecting arc-shaped platform 612. The first connecting boss 611 is symmetrically arranged at both ends of the first connecting arc-shaped platform 612; The shape of the first connecting arc-shaped platform 612 matches the shape of the first receiving groove 21; The size of the first connecting arc-shaped platform 612 is smaller than the slot size of the first receiving groove 21; The height of the first connecting arc-shaped platform 612 is less than the depth of the first receiving groove 21.

[0046] Specifically, the first connecting boss 611 refers to a small protrusion structure integrated on the inner surface of the second housing 50, which is specifically designed to cooperate with the corresponding structure of the first housing 10 to limit the relative displacement between the second housing 50 and the first housing 10; the first connecting arc-shaped platform 612 refers to an arc-shaped protrusion structure also provided on the inner surface of the second housing 50, whose arc-shaped contour is completely fitted with the arc-shaped groove wall of the first receiving groove 21 on the first housing 10, so as to achieve the main body protection and pressure of the artificial blood vessel.

[0047] There are two first connecting protrusions 611, symmetrically distributed at both ends of the first connecting arc-shaped platform 612. The first connecting arc-shaped platform 612 is an elongated arc shape, with the two protrusions located at the left starting point and the right ending point of the arc, respectively. All three are integrally formed, forming a structure with two first connecting protrusions 611 at both ends and one first connecting arc-shaped platform 612 in the middle, namely the first structure 61. The first structure 61 covers the length direction of the first receiving groove 21. When the second housing 50 is fastened, the first connecting arc-shaped platform 612 can be precisely aligned with the opening of the first receiving groove 21, and the first connecting protrusions 611 can be precisely aligned with the corresponding pre-set connecting structures on the first housing 10.

[0048] In the engaged state, the first connecting boss 611 is embedded in the corresponding connecting structure of the first housing 10, and the first connecting arc-shaped platform 612 is suspended above the opening of the first receiving groove 21, without making hard contact with the groove wall of the first receiving groove 21, retaining a small gap. The two work together to make the second housing 50 and the first housing 10 form a stable connection in the area of ​​the first receiving groove 21, and without leaving the coverage area of ​​the artificial blood vessel body.

[0049] The arc-shaped contour of the first connecting arc-shaped platform 612 fits the first receiving groove 21, which can specifically cover the artificial blood vessel body in the groove. At the same time, the design of the arc-shaped platform being smaller than the opening size of the first receiving groove 21 ensures that the arc-shaped platform will not fill the first receiving groove 21, leaving room for the artificial blood vessel body to move, avoiding excessive pressure that could damage the artificial blood vessel wall, and restricting the body from moving along the width of the groove. The design of the height of the first connecting arc-shaped platform 612 being smaller than the depth of the first receiving groove 21 allows the arc-shaped platform to be suspended above the artificial blood vessel body in the groove, without directly contacting or only slightly contacting the artificial blood vessel body. It can prevent the blood vessel from tilting up in the vertical direction through slight holding force, and will not compress the blood vessel due to excessive height.

[0050] In some implementations, refer to Figure 1 and Figure 2 The first connecting protrusion 611 is disconnected at the midpoint of the connection between the first receiving groove 21 and the branch receiving groove 22, forming a clearance notch 613. Specifically, the clearance notch 613 refers to a recessed structure opened in the middle of the length direction of the first connecting arc-shaped platform 612. The whole can be arc-shaped, rectangular, or an irregular shape that matches the contour of the connection between the first receiving groove 21 and the branch receiving groove 22. It is specifically used to avoid the connection between the first receiving groove 21 and the branch receiving groove 22 on the first housing 10. Its recessed depth depends on the vertical height of the fourth branch blood vessel, thus creating a clearance notch 613 on the first connecting arc-shaped platform 612 for the fourth branch blood vessel to pass through. Because the vertical height of the fourth branch blood vessel is higher than that of the artificial blood vessel body, this means that the first connecting arc-shaped platform 612, which is in light contact with the artificial blood vessel body, will directly cover and compress the protruding part of the fourth branch blood vessel, causing deformation of the vessel wall or tearing of the connection part. The recessed space of the clearance notch 613 can fully accommodate the vertical protrusion of the fourth branch, thereby resolving the structural contradiction between the holding body and the clearance branch.

[0051] In some implementations, refer to Figure 1 and Figure 2 The first housing 10 has a first connecting groove 70 at the position corresponding to the first connecting boss 611, and the first connecting boss 611 is at least partially engaged within the first connecting groove 70. Specifically, if only the fixing structure at the edge of the second housing 50 is used, the second housing 50 is prone to shift due to the deviation of the fastening angle, which in turn causes the first connecting arc-shaped platform 612 to deviate from the first receiving groove 21. However, the engagement of the first connecting boss 611 with the first connecting groove 70 can form a hard limit from both ends of the first receiving groove 21, forcing the second housing 50 to remain horizontally engaged, ensuring that the first connecting arc-shaped platform 612 is always aligned with the first receiving groove 21 and does not shift to other areas.

[0052] In some implementations, refer to Figure 1 and Figure 2The first housing 10 has a first protrusion 80 below the first receiving groove 21, and a second connecting groove 90 is formed on the first protrusion 80. The fixing structure includes: The second structure includes a second connecting boss 62, which is at least partially engaged within the second connecting groove 90.

[0053] Specifically, the first structure 61 is positioned above the first receiving groove 21, and the second structure is positioned below the first receiving groove 21. The two are synchronously distributed along the length of the first receiving groove 21, which can restrict the horizontal displacement of the second housing 50 from both the upper and lower dimensions, ensuring that the second housing 50 is always precisely aligned with the first receiving groove 21 after being fastened, without any deviation.

[0054] In some implementations, refer to Figure 1 and Figure 2 The first housing 10 is provided with a third connecting groove 100 on both sides of the first receiving groove 21; The fixing structure includes: The third structure includes a third connecting boss 63, which engages within the third connecting groove 100.

[0055] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
