[0002] In the related art, the temporary occlusion of blood vessels usually needs to be operated with the aid of a vascular occluding forceps. However, the method of directly clamping blood vessels with a vascular occluding forceps is not convenient for subsequent surgical operations due to the large space occupied by the vascular occluding forceps. Summary of the Invention

[0003] The purpose of the present disclosure is to provide a vascular occluder and a vascular occluder assembly, which can stably clamp blood vessels, achieve the purpose of temporarily occluding blood vessels, and have the advantages of high safety, strong reliability and convenient operation.

[0004] To achieve the above purpose, in the first aspect of the present disclosure, a vascular occluder is provided. The vascular occluder includes: an occlusion tube, a support part is arranged in the occlusion tube, and the support part is configured to deform under the action of an external force so that the occlusion tube deforms into a preset shape for clamping blood vessels; and a locking part for unlockably locking the occlusion tube in the preset shape.

[0005] Optionally, the support part includes a plurality of spherical elements arranged in the occlusion tube, and the plurality of spherical elements are arranged along the extending direction of the occlusion tube. When the occlusion tube clamps the blood vessels, the plurality of spherical elements gather together so that the occlusion tube deforms into the preset shape.

[0006] Optionally, a groove structure for frictionally cooperating with another spherical element is formed on the outer wall surface of one of the adjacent two spherical elements.

[0007] Optionally, the spherical element includes one of a metal ball, a hard plastic ball, and a hard synthetic resin ball.

[0008] Optionally, the support part further includes a connecting rope for serially connecting the plurality of spherical elements.

[0009] Optionally, the connecting rope is a nitinol wire.

[0010] Optionally, the blocking tube has a collar portion for clamping the blood vessel in the preset shape, and two pulling portions connected to and butting against the collar portion. The locking portion surrounds the two pulling portions and is locked between two adjacent spherical elements at the connection of the collar portion and the pulling portion, so that the blocking tube is maintained in the preset shape; wherein, by changing the position of the locking portion relative to the two pulling portions, the collar portion can be contracted or expanded.

[0011] Optionally, the locking portion includes a shaping clip.

[0012] Optionally, the blocking tube is made of a compliant material.

[0013] A second aspect of the present disclosure provides a blood vessel blocker assembly, including a blocking forceps and the blood vessel blocker provided in the first aspect above. The blocking forceps is used to provide the external force to deform the blocking tube into the preset shape.

[0014] Through the above technical solution, that is, the blood vessel blocker provided by the present disclosure, the support portion in the blocking tube of the blood vessel blocker is configured to be deformable under the action of an external force so that the blocking tube is deformed into a preset shape, and can be stably locked in the preset shape through the locking portion. Thus, the blood vessel can be stably clamped through the blood vessel blocker to achieve the purpose of temporarily blocking the blood vessel. And compared with the method of directly clamping the blood vessel by, for example, a blood vessel blocking forceps in the related art, since the blocking tube of the blood vessel blocker provided by the present disclosure is easy to bend, deform and fold, it is convenient for medical staff to adaptively adjust the position and shape of the blocking tube according to the surgical needs, with high flexibility.

Detailed description of the specific implementation mode

[0018] The following is a detailed description of the specific implementation mode of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation mode described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] It should be noted that all actions of obtaining signals, information or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located, and with the authorization given by the owner of the corresponding device.

[0020] In the present disclosure, unless otherwise stated, "inside and outside" refer to the inside and outside relative to the contour of the component or structure itself. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another, and do not have sequence and importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0021] According to a first aspect of the present disclosure, a blood vessel blocker is provided, with reference to Figures 1 to 6As shown, the vascular occluder 100 includes an occlusion tube 110 and a locking portion 130. Among them, a support portion 120 is arranged inside the occlusion tube 110. The support portion 120 is configured to be deformed under the action of an external force so that the occlusion tube 110 is deformed into a preset shape for clamping the blood vessel 200. The locking portion 130 is used to lock the occlusion tube 110 to the preset shape in an unlockable manner.

[0022] Through the above technical solution, that is, the vascular occluder 100 provided by the present disclosure, the vascular occluder 100 can be deformed into a preset shape by configuring the support portion 120 inside the occlusion tube 110 under the action of an external force, and can be stably locked to the preset shape through the locking portion 130. Thus, the blood vessel 200 can be stably clamped through the vascular occluder 100 to achieve the purpose of temporarily occluding the blood vessel 200. And compared with the method of directly clamping the blood vessel by, for example, a vascular occluding forceps in the related art, since the occlusion tube 110 of the vascular occluder 100 provided by the present disclosure is easy to bend, deform and fold, it is convenient for medical staff to adaptively adjust the position and shape of the occlusion tube 110 according to the surgical needs, with high flexibility. Moreover, the overall structural space occupied by the vascular occluder 100 is also small, which can reduce the interference with other instruments and surgical operations during the operation and contribute to the development of the surgical operation.

[0023] In addition, by arranging the support portion 120 inside the occlusion tube 110, the present disclosure can also improve the reliability and durability of the overall structure of the occlusion tube 110, enable the occlusion tube 110 to withstand greater pressure, reduce the risk of the occlusion tube 110 breaking or failing, improve the safety of the surgical operation, and the high strength of the occlusion tube 110 can also reduce the replacement frequency and lower the medical cost. Therefore, the vascular occluder 100 provided by the present disclosure can stably clamp the blood vessel 200 to achieve the purpose of temporarily occluding the blood vessel 200, and has the advantages of high safety, strong reliability and convenient operation.

[0024] Among them, the support portion 120 inside the occlusion tube 110 can be deformed under the action of an external force so that the occlusion tube 110 is deformed into a preset shape to clamp the blood vessel 200. Exemplarily, for example Figure 2As shown, the support portion 120 within the blocking tube 110 can be deformed, for example, under the action of the blocking forceps 300, so that the blocking tube 110 is deformed into a preset shape for clamping the blood vessel 200. Or, in some embodiments not shown, the support portion 120 within the blocking tube 110 can also be deformed, for example, by pinching with the hand, so that the blocking tube 110 is deformed into a preset shape for clamping the blood vessel 200. The present disclosure does not specifically limit such deformation methods, and those skilled in the art can adaptively adjust according to actual application requirements. The purpose is to enable the support portion 120 within the blocking tube 110 to be deformed under an external force so that the blocking tube 110 can be deformed into a preset shape for clamping the blood vessel 200.

[0025] The support portion 120 can be adaptively designed according to actual application requirements. For example, in some embodiments, referring to Figures 1 to 6 As shown, the support portion 120 can include a plurality of spherical elements 121 disposed within the blocking tube 110. The plurality of spherical elements 121 are arranged along the extending direction of the blocking tube 110. When the blocking tube 110 clamps the blood vessel 200, the plurality of spherical elements 121 gather together so that the blocking tube 110 is deformed into a preset shape. Arranged in this way, the support for the blocking tube 110 can be achieved through the plurality of spherical elements 121 disposed within the blocking tube 110, the external pressure can be dispersed, the local stress concentration can be reduced, the compressive capacity of the overall structure of the blocking tube 110 can be improved, which helps to ensure that the blocking tube 110 can stably clamp the blood vessel 200, and the reliability is relatively high.

[0026] Among them, as Figure 6 As shown, in some embodiments, on the outer wall surface of one of the adjacent two spherical elements 121, a groove structure 122 for frictionally cooperating with the other spherical element 121 can be formed. Arranged in this way, when the plurality of spherical elements 121 gather together, the plurality of spherical elements 121 can be in close contact through the frictional cooperation between the spherical elements 121 and the groove structure 122, reducing the possibility of relative movement between the plurality of spherical elements 121, which helps to ensure that the blocking tube 110 can stably maintain the above-mentioned preset shape, and thus can stably clamp the blood vessel 200, with high reliability.

[0027] In addition, in some embodiments, the above-mentioned spherical element 121 can include one of a metal ball, a hard plastic ball, and a hard synthetic resin ball. Arranged in this way, it can be ensured that the spherical element 121 has a relatively high structural strength, so as to achieve the purpose of stably supporting the blocking tube 110, improve the compressive capacity of the overall structure of the blocking tube 110, which helps to ensure that the blocking tube 110 can stably clamp the blood vessel 200, and the reliability is relatively high.

[0028] In addition, in some embodiments, referring to Figures 1 to 6As shown, the support part 120 may further include a connecting rope 123 for connecting a plurality of spherical elements 121 in series. In this way, the connecting rope 123 can play a role in limiting the plurality of spherical elements 121, so as to realize the stable arrangement of the plurality of spherical elements 121 in sequence along the extending direction of the blocking tube 110. This is convenient for the plurality of spherical elements 121 to gather when the blocking tube 110 clamps the blood vessel 200 and enables the blocking tube 110 to be shaped into a preset shape for clamping the blood vessel 200. Moreover, through the arrangement of the connecting rope 123, even if a rupture occurs at a local position where the blocking tube 110 is not in contact with the blood vessel 200, for example, the connecting rope 123 can still enable the plurality of spherical elements 121 to remain stably in the above preset shape, reducing the impact of emergencies on the surgical operation and improving safety.

[0029] Among them, in some embodiments, in order to ensure that the connecting rope 123 has good fatigue resistance, the connecting rope 123 can be, for example, a nitinol wire, or the connecting rope 123 can also be, for example, a cobalt-chromium alloy wire. The present disclosure does not make specific limitations on such deformation methods, and those skilled in the art can adaptively design according to actual application requirements.

[0030] In addition, in order to ensure that the blocking tube 110 can stably clamp the blood vessel 200 and is convenient for operation, in some embodiments, as shown in Figures 1 to 5 the blocking tube 110 may have a collar part 111 for clamping the blood vessel 200 and two pulling parts 112 connected to and in butt joint with the collar part 111 in the preset shape. The locking part 130 surrounds the two pulling parts 112 and is locked between two adjacent spherical elements 121 at the connection between the collar part 111 and the pulling part 112, so as to keep the blocking tube 110 in the preset shape, so as to achieve the purpose of temporarily blocking the blood vessel 200, with high reliability and convenient operation.

[0031] Among them, in order to facilitate on-site medical staff to adaptively adjust the tightening degree of the collar part 111 according to different surgical needs, in some embodiments, as shown in Figure 3As shown, by changing the position of the locking portion 130 relative to the two pulling portions 112, the collar portion 111 can be contracted or expanded. That is, it can be understood that by operating the locking portion 130 to move towards the side close to the blood vessel 200 relative to the two pulling portions 112, the contraction of the collar portion 111 can be achieved. Or, the expansion of the collar portion 111 can also be achieved by operating the locking portion 130 to move towards the side away from the blood vessel 200 relative to the two pulling portions 112. In summary, by changing the position of the locking portion 130 relative to the two pulling portions 112, the collar portion 111 can be contracted or expanded to adjust the tightening force of the blocking tube 110 for clamping the blood vessel 200, reduce the damage to the blood vessel 200 caused by excessive tightening force, and at the same time reduce the risk that the blocking tube 110 cannot stably clamp the blood vessel 200 due to insufficient tightening force.

[0032] It should be noted that since the collar portion 111 can be contracted or expanded by changing the position of the locking portion 130 relative to the two pulling portions 112, it can be understood that the connection between the collar portion 111 and the pulling portion 112 described above is variable. The locking position of the locking portion 130 (i.e., the position of the connection between the collar portion 111 and the pulling portion 112 where the locking portion 130 locks when the blocking tube 110 is in the preset shape) can be understood as follows: after adjusting the collar portion 111 of the blocking tube 110 to an appropriate tightening degree and clamping the blood vessel 200 according to the corresponding surgical requirements, in order to enable the blocking tube 110 to maintain the current preset shape, the locking portion 130 can be locked at the connection between the collar portion 111 and the pulling portion 112 in the preset shape, so as to achieve the purpose of stably clamping the blood vessel 200 by the blocking tube 110.

[0033] In addition, since the locking portion 130 can be locked between two adjacent spherical elements 121 at the connection between the collar portion 111 and the pulling portion 112 when the blocking tube 110 is in the preset shape, arranged in this way, when the locking portion 130 includes, for example, a shaping clip, not only can the blocking tube 110 be stably clamped by the shaping clip, but also the shaping clip can be limited and fixed by two adjacent spherical elements 121 in the blocking tube 110, thereby further improving the connection reliability of the shaping clip and helping to ensure that the blocking tube 110 can stably maintain the preset shape and stably clamp the blood vessel 200.

[0034] Among them, the present disclosure does not specifically limit the specific structure and material of the above-mentioned shaping clip. The purpose is to be able to stably clamp the blocking tube 110 through the shaping clip so that the blocking tube 110 can be maintained in a preset shape for clamping the blood vessel 200. Those skilled in the art can adaptively design according to actual application requirements. Of course, the above-mentioned locking portion 130 is not limited to the shaping clip. In some alternative embodiments, the locking portion 130 can also be, for example, a hoop. It can be understood that after the collar portion 111 of the blocking tube 110 is adjusted to an appropriate tightening degree and clamps the blood vessel 200 according to the corresponding surgical requirements, in order to make the blocking tube 110 maintain the current preset shape, the hoop can be locked at the connection between the collar portion 111 and the pulling portion 112 in the preset shape, so as to achieve the purpose of stably clamping the blood vessel 200 through the blocking tube 110. The hoop can be constructed in any suitable manner. For example, the hoop can be constructed to be able to adjust the tightening degree to adjust the diameter of the hoop, so as to change the position of the hoop relative to the two pulling portions 112, so that the collar portion 111 can contract or expand. The present disclosure is not limited thereto.

[0035] In addition, it should be noted that in the specific embodiment where the locking portion 130 is locked between two adjacent spherical elements 121 at the connection between the collar portion 111 and the pulling portion 112 when the blocking tube 110 is in the preset shape of clamping the blood vessel 200, it is exemplary. In some alternative embodiments, the locking portion 130 can also be locked outside the two spherical elements 121 at both ends among the plurality of spherical elements 121. In this way, it is also possible to only clamp the locking portion 130, which is constructed as a shaping clip for example, on the blocking tube 110 and realize the limit fixation of the plurality of spherical elements 121. The present disclosure does not specifically limit such deformation methods, and those skilled in the art can adaptively design according to actual application requirements.

[0036] In addition, the preset shape when the above-mentioned blocking tube 110 clamps the blood vessel 200 can be, for example, Figure 3 the collar shape shown in, which is simple in structure and convenient to operate, so as to achieve the purpose of stably clamping the blood vessel 200 through the blocking tube 110. In addition, in some other embodiments not shown in the drawings, a friction layer can be provided between the locking portion 130 (such as a shaping clip) and the blocking tube 110, so as to improve the friction force between the locking portion 130 (such as a shaping clip) and the blocking tube 110, reduce the possibility of the locking portion 130 (such as a shaping clip) sliding on the blocking tube 110, and achieve the purpose of stably clamping the blood vessel 200 through the blocking tube 110, with high reliability.

[0037] In some embodiments, considering the need to improve surgical safety, the occlusion tube 110 can be made of a compliant material. Exemplarily, the compliant material can be a polymer material such as rubber, silicone, or polyvinyl chloride (PVC). Since the occlusion tube 110 made of the compliant material is relatively soft, when the occlusion tube 110 is attached to the blood vessel 200, the possibility of damaging the blood vessel 200 can be reduced, thereby improving safety and comfort.

[0038] In addition, it should be noted that as Figure 3 shown, after the above-mentioned occlusion tube 110 is made of a compliant material and a support part 120 configured as a spherical element 121 is placed inside the occlusion tube 110, the two ends of the occlusion tube 110 can be sealed, so as to stably arrange a plurality of spherical elements 121 inside the occlusion tube 110, so that the support part 120 configured as a spherical element 121 inside the occlusion tube 110 can deform under the action of an external force to make the occlusion tube 110 deform into a preset shape for the purpose of clamping the blood vessel 200. Among them, the above-mentioned connecting rope 123 can be arranged inside the occlusion tube 110 and fixedly connected to the two ends of the occlusion tube 110, or can also be arranged through the occlusion tube 110 and have a rope body located outside the occlusion tube 110, and the connecting rope 123 is fixedly connected to the two ends of the occlusion tube 110. The present disclosure does not specifically limit such deformation methods. The purpose is to be able to connect a plurality of spherical elements 121 in series through the connecting rope 123, and stably arrange a plurality of spherical elements 121 in sequence along the extension direction of the occlusion tube 110, so that when the occlusion tube 110 clamps the blood vessel 200, a plurality of spherical elements 121 can be gathered and the occlusion tube 110 can be shaped into a preset shape for clamping the blood vessel 200.

[0039] According to a second aspect of the present disclosure, there is provided a blood vessel occluder assembly, which includes an occlusion forceps 300 and the blood vessel occluder 100 provided in the first aspect above. The occlusion forceps 300 is used to provide an external force to make the occlusion tube 110 deform into a preset shape, so as to stably clamp the blood vessel and achieve the purpose of temporarily occluding the blood vessel. In addition, the blood vessel occluder assembly also has all the beneficial effects of the blood vessel occluder 100 provided in the first aspect above, and the present disclosure will not elaborate herein.

[0040] Among them, the present disclosure does not specifically limit the specific structure of the occlusion forceps 300. The purpose is to be able to clamp the occlusion tube 110 and deform it into a preset shape to clamp the blood vessel 200, and those skilled in the art can adaptively design according to actual application requirements.

[0041] Based on the above embodiments, the present disclosure exemplarily describes the operation process of the blood vessel occluder assembly. Exemplarily, for example, as Figure 1As shown, medical staff can first wind the blocking tube 110 around the blood vessel 200 through, for example, existing surgical techniques, and then as Figure 2 shown, with the aid of the blocking forceps 300, the blocking tube 110 is clamped to form a preset shape (such as a sleeve shape) to complete the shaping operation of the blocking tube 110, so as to clamp the blood vessel 200. Then, the locking part 130 is locked between two adjacent spherical elements 121 at the connection of the sleeve part 111 and the pulling part 112. In this way, as Figure 3 shown, after the blocking forceps 300 are removed, the blocking tube 110 can be kept in the preset shape through the locking part 130 to achieve the purpose of temporarily blocking the blood vessel 200. Since the overall structural space of the blood vessel blocker 100 is relatively small, it can reduce the interference with other instruments and surgical operations during the operation, which is helpful for the development of the surgical operation. Moreover, by changing the position of the locking part 130 relative to the two pulling parts 112, the sleeve part 111 can be contracted or expanded, so as to adjust the tightening force of the blocking tube 110 for clamping the blood vessel 200, reduce the damage to the blood vessel 200 caused by excessive tightening force, and at the same time, it can also reduce the risk that the blocking tube 110 cannot stably clamp the blood vessel 200 due to insufficient tightening force, improving safety and comfort.

[0042] The preferred embodiments of the present disclosure have been described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept scope of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0043] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination manners.

[0044] In addition, any combination can be made between various different embodiments of the present disclosure as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
