Description

Blocking device for blocking blood vessel

Technical Field

The invention relates to the field of medical appliances for shell surgery, in particular to a blocking device for blocking blood vessels.

Background

Treatment of skin lesions (including burn scars, congenital tumors, trauma or post-operative scars) has been a difficult problem in orthopedics. Traditional skin grafting procedures can create an unsightly "patch" like appearance. In addition, the skin donor area can leave unsightly donor area scars. Skin dilator technology was first reported by neumann1957 and is a revolutionary technological advance. Because of its advantages, 1, the skin can develop new skin after being expanded by the skin expander, just like the pregnant woman's abdomen can develop extra skin. After the skin is excised for transplantation repair, only linear scars are left in the supply area, unlike the skin supply area of the prior skin grafting, and flaky scars are left; 2. if the skin flap near the skin lesion is expanded, the skin flap with similar color and texture can be provided, and the repairing effect is optimal. Due to the above advantages, skin expander technology has been vigorously developed in recent years. However, one of the common complications of this technique after surgery is the occurrence of partial necrosis after the transfer of the dilated flap. The reason for this is mainly that the area of the expanded flap is too large, exceeding the limit of blood supply. Clinically, if the skin flap is to survive, sufficient blood supply needs to be ensured. To ensure adequate blood supply, the flap design must follow a certain aspect ratio to ensure that the blood pressure is sufficient to supply the distal-most end of the flap. If the aspect ratio of the peel flaps exceeds this ratio, a delayed surgery is required.

The surgical delay surgery is to cut off the blood supply in multiple directions around the flap, leaving only the blood supply in the future. In this way, blood vessels in a specific direction within the skin flap are thickened, in which direction the blood supply capacity is enhanced, and longer skin flaps can be supplied. Through the surgical delay operation, the length of the skin flap can survive even if exceeding the limit of the traditional aspect ratio, and the blood supply disorder can not occur. The surgical delay procedure is equally applicable to dilating flaps. That is, the expanded skin flap can also be provided with a surgical delay operation to prevent the occurrence of blood supply disorder after the transfer of the expanded skin flap. There are still some disadvantages to this surgical delay procedure. First, delayed surgery often uses a single cut of unwanted blood supply, leaving only the skin flap of the blood supply, in hopes of enhancing the blood supply from the stem. However, this blood supply is very variable and is not a progressive blood supply training. It is possible to cause a sudden decrease in blood supply to the skin flap, leading to necrosis of the skin flap. Second, adding one surgical delay represents more expense or more pain to the patient. In addition, the risk of infection increases.

Description of the embodiments

The following description is presented to enable one of ordinary skill in the art to make and use the invention. The preferred embodiments provided in the following description are merely examples and modifications apparent to those skilled in the art and do not constitute a limitation on the scope of the invention. The general principles defined in the following description may be applied to other embodiments, alternatives, modifications, equivalents and applications without departing from the spirit and scope of the invention.

Referring to fig. 1 to 6, a blocking device for blocking a blood vessel according to a preferred embodiment of the present invention is described in detail below, wherein the blocking device 100 for blocking a blood vessel includes a fixing frame 10 and at least two locking members 20 provided to the fixing frame 10.

Specifically, the fixing frame 10 includes a bridge 11 and a supporting arm 12 respectively disposed at two ends of the bridge 11. The bridge 11 of the mount 10 defines an opening 110 between the two support arms 12. When the blocking device 100 for blocking blood vessels is used for blocking blood vessels, the two support arms 12 are respectively supported at corresponding positions of an acting object, such as a human body, wherein the opening 110 of the fixing frame 10 allows the blood vessels to be reserved on the acting object to pass through.

In one embodiment of the invention, two of the support arms 12 are embodied to extend integrally from the bridge 11. Each support arm 12 has a support surface 120 to enhance stability of the mount 10 by being in surface contact with the object when the mount 10 is secured to the object 200.

Preferably, the two support arms 12 are rotatably connected to both ends of the bridge 11, so that the inclination of the support surface 120 of the support arm 12 can be automatically adjusted according to the change of the acting object after the fixing frame 10 is fixed to the acting object, so as to improve the stability of the fixing frame 10 relative to the acting object by ensuring sufficient contact between the support surface 120 of the support arm 12 and the acting object.

Specifically, the bridge 11 has two lower ends 111 and at least one higher end 112 opposite to the lower ends 111, wherein the bridge 11 is implemented to extend from the lower ends 111 to the higher ends 112, respectively, to form the opening 110 between the two lower ends 111. Each of the support arms 12 is connected to each of the lower ends 111 of the bridge 11. Preferably, each supporting arm 12 is rotatably connected to each lower end 111, so that after the fixing frame 10 is mounted on the acting object, the supporting surfaces 120 of the two supporting arms 12 can automatically adjust an angle between the supporting arms and the acting object, and further, the supporting arms can be better fitted with the acting object. More specifically, a rotating structure 13 is provided near each of the bridges of the lower ends 111. Correspondingly, a rotating structure 14 is provided at a corresponding position of each supporting arm 12, which is adapted to the rotating structure 13. It should be noted that the rotation structure 13 may be implemented as a pair of grooves or a pair of protrusions provided at both sides of the bridge 11 of each of the lower ends 111, and accordingly the rotation structure 14 may be implemented as a pair of protrusions or grooves adapted to the grooves or protrusions.

Preferably, the bridge 11 is shaped as an arc. More preferably, the two lower ends 111 of the bridge 11 are symmetrically disposed, and in this case, the bridge 11 has one of the upper ends 112, and the upper end 112 of the bridge 11 is the arc top of the bridge 11.

The bridge 11 further comprises a first bridge 113 and a second bridge 114, wherein the first bridge 113 and the second bridge 114 are capable of forming the bridge 11 after being connected to each other. Preferably, in the present invention, the first bridge 113 and the second bridge 114 have an arc shape, so that the arc-shaped bridge can be formed.

Preferably, the blocking device 100 for blocking a blood vessel further comprises a packing member 30, wherein the packing member 30 has two free ends 31, a first free end 31a and a second free end 31b, respectively.

The locking members 20 are mounted to the mount 10, and one of the locking members 20 is disposed between one of the low ends 111 and the high ends 112, with the other locking member 20 being disposed between the other of the low ends 111 and the high ends 112.

The portion of the tightening member 30 adjacent to one of the free ends 31 is secured to one of the locking members 20 of the bridge 11 disposed between one of the low ends 111 and the high end 112. The portion of the packing 30 adjacent to the other of the free ends 31 can be locked by the other of the locking members 20.

When the blocking device 100 for blocking blood vessels is applied to the object 200, the two support arms 12 of the fixing frame 10 are supported on the object, and the two support arms 12 are respectively positioned at two sides of the extending path of the blood vessels to be reserved, so that the opening 110 formed by the bridge 11 just allows the blood vessels to be reserved to pass through. In addition, after the tightening member 30 is wound around the corresponding portion of the acting object and the tightening member 30 is intersected with the blood vessel to be cut, the tightening member 30 is fixed to the locking member 20 near each of the free ends 31, so that the tightening member 30 can apply a certain amount of pressure to the blood vessel to be cut on the acting object. In this way, the blocking device 100 for blocking blood vessels can further achieve the excision of the corresponding blood vessel by pressing the blood vessel to be blocked on the object.

It should be noted that, since the portion of the packing 30 contacting the acting object is just the blood vessel to be cut, the blood vessel to be cut of the acting object is difficult to convey blood under the compression of the packing 30. Thus, after the blood vessel blocking device 100 is used repeatedly, the blood vessel to be cut is gradually cut. In addition, since the opening 110 formed by the bridge 11 is partially free from the packing member 30, the blood vessel passing through the opening 110 and located on the subject will not be pressed by the packing member 30, and after the blocking device 100 for blocking blood vessels is used a plurality of times, the blood vessel to be preserved on the subject can be trained to supply blood to a specific site, and over time, the blood vessel to be preserved on the subject will be able to supply blood to a longer skin flap.

It will be appreciated by those skilled in the art that the vascular occlusion device 100 provided by the present invention can be used to not only occlude a blood vessel to be occluded, but also to retain a blood vessel to be retained.

From the above description, the blocking device 100 for blocking blood vessels according to the present invention can form a blood vessel blocking region 1001 and a blood vessel retaining region 1002. The blood vessel located in the blood vessel blocking area 1001 can be pressed by the blocking device 100 blocking the blood vessel, and the blood vessel located in the blood vessel retaining area 1002 can be enhanced in the ability to supply blood to the corresponding site on the subject located in the blood vessel blocking area 1001.

For example, in the present invention, the packing 30 has two free ends 31, wherein after the packing 30 is fixed to the fixing frame 10 at a portion near each of the free ends 31, the packing 30 presses the portion of the acting object to form the blood vessel blocking area 1001, and the opening 110 formed in the bridge 11 of the fixing frame 10 is such that the fixing frame 10 corresponds to the blood vessel retaining area at a portion not in contact with the acting object.

Further, in one embodiment of the present invention, the fixing frame 10 further forms at least one first limiting channel 101, wherein the first limiting channel 101 has a first inlet 1011 and a first outlet 1012, wherein the first inlet 1011 of the first limiting channel 101 is disposed near one of the low ends 111 of the bridge 11, and wherein the first outlet 1012 is disposed near one side of the high end 112 of the bridge 11. The first limiting channel 101 extends from the low end 111 of the bridge 11 to the high end 112 of the bridge 11. The locking member 20 is disposed on the bridge 11 and located on the first limiting channel 101, and the locking member 20 is located between the first inlet 1011 and the first outlet 1012 of the first limiting channel 101.

In an embodiment of the present invention, one free end 31 of the packing 30 is fixed to the bridge 11 of the fixing frame 10, and the other free end 31 of the packing 30 passes through the first inlet 1011 of the first limiting channel 101 and extends out of the first limiting channel 101 from the first outlet 1012 after passing through the first limiting channel 101. The extended packing 30 will form the vascular occlusion region 1001 after being fixed by the locking member 20.

In order for those skilled in the art to understand the present invention, one of the free ends 31 of the bridge 11 fixed to the fixing frame 10 is defined as the first free end 31a, and the free end 31 passing through the limiting passage 101 and the first inlet 1011 is defined as the second free end 31b in the following embodiments of the present invention. Those skilled in the art will appreciate that the present invention is not limited in this respect.

Therefore, when the blocking device 100 for blocking blood vessels is used to block blood vessels of the acting object, the two supporting arms 12 of the fixing frame 10 are first supported on the acting object, the tightening members 30 are tied to the corresponding parts of the acting object, and the openings 110 formed in the bridge 11 are kept to allow the blood vessels to be retained on the acting object to pass through. Subsequently, the second free end 31b of the packing 30 is passed through the first inlet 1011 of the first limiting channel 101 and extends out of the first limiting channel 101 from the first outlet 1012 of the first limiting channel 101, after which the packing 30 is secured by the locking member 20 to maintain the pressure of the packing 30 against the blood vessel on the subject to be blocked.

It should be noted that, when the pressure applied by the tightening member 30 to the acting object needs to be increased, the second free end 31b of the tightening member 30 may be further tightened, so that the pressure of the tightening member 30 pressing the blood vessel to be blocked on the acting object may be increased. Conversely, when it is necessary to reduce the pressure exerted by the packing 30 on the acting object, it is only necessary to loosen the second free end 31b of the packing 30 and then to fix the packing 30 again by the locking member 20, thereby enabling the pressure of the packing 30 pressing the blood vessel to be blocked on the acting object to be reduced.

As will be appreciated by those skilled in the art, the blood supply to the corresponding portion of the subject is gradually reduced after the blood vessel is compressed by the application of a certain amount of pressure to the blood vessel to be blocked by the tensioned blocking device 100. Accordingly, the blood vessel to be preserved on the subject passing through the opening 110 will gradually be enhanced in blood supply to the corresponding site on the subject.

It will be appreciated by those skilled in the art that in the present invention, there is no need to perform a surgical operation on the subject after the vascular occlusion device 100 acts on the subject. In other words, the blood vessel blocking device 100 according to the present invention is used without causing physical damage to the subject. Furthermore, the blood vessel blocking device 100 according to the present invention can adjust the pressure of the blood vessel to be blocked by tightening and loosening the second free end 31b of the tightening member 30, that is, the blood vessel blocking device 100 according to the present invention can apply pressure of different sizes in different stages of the blood vessel to be blocked.

It is worth mentioning that in the present invention, the tightening member 30 is preferably implemented as made of an elastic material, such as rubber or the like. Preferably, the packing 30 is embodied as being made of a solid rubber material. For example, the packing 30 may be implemented to be made of a solid rubber tube.

Preferably, in the present invention, the locking member 20 is provided to the bridge 11. The locking member 20 is capable of being switched between an adjustment state and a locking state. When the locking member 20 is in the locked state, the urging member 30 near the second free end 31b will be pressed by the locking member 20, thereby enabling the urging member 30 to press the blood vessel to be blocked on the acting object. When the locking member 20 is in the adjustment state, the pressure with which the urging member 30 presses the acting object can be adjusted by tightening and loosening the urging member 30.

Specifically, the locking member 20 is rotatably connected to the bridge 11. More specifically, the bridge 11 between the first inlet 1011 and the first outlet 1012 of the first limiting passage 101 forms a gap 15 communicating with the first limiting passage 101. The bridge 11 has a first sidewall 1101 and a second sidewall 1102, wherein the gap 15 is formed between the first sidewall 1101 and the second sidewall 1102. The first side wall 1101 and the second side wall 1102 are respectively provided with a connecting structure 16, wherein the locking piece 20 is correspondingly provided with a mounting structure 21 matched with the connecting structure 16, and the mounting structure 21 is rotatably connected with the connecting structure 16. Preferably, in an embodiment of the present invention, the connection structure 16 is implemented as a pair of grooves or a pair of protrusions provided on the first side wall 1101 and the second side wall 1102 of the notch 15. The mounting structure 21 is implemented as a pair of protrusions or a pair of grooves provided on the locking member 20 and adapted to the connection structure 16 on the first side wall 1101 and the second side wall 1102. In this way, the locking element 20 is in turn rotatably mounted to the bridge 11.

Further, the bridge 11 further has a fixing wall 1103, and the fixing wall 1103 is provided with a fixing structure 17, wherein at least one locking structure 22 adapted to the fixing structure 17 is provided at a corresponding position of the fixing wall 1103 and the locking member 20. When the locking member 20 is in the locked state, the locking structure 22 of the locking member 20 is locked with respect to the fixing structure 17. However, when the locking member 20 is in the adjustment state, the locking structure 22 is opened with respect to the fixed structure 17, and the locking member 20 is rotatable with respect to the bridge 11 by the mounting structure 21. In this way, the locking element 20 can be switched between the locked state and the adjustment state.

It should be noted that, in the present invention, the locking member 20 is snappingly fixable to the bridge 11 by the fixing structure 17 and the locking structure 22.

It should be noted that, after the second free end 31b of the packing member 30 passes through the first inlet 1011 of the first limiting channel 101 and extends from the first outlet 1012 of the first limiting channel 101, when the locking member 20 is in the locked rotation state, the locking member 20 compresses the packing member 30, so that the packing member 30 is fixed by the locking member 20.

More preferably, the fixing frame 10 further forms a second limiting channel 102, wherein the second limiting channel 102 has a second inlet 1021 and a second outlet 1022, wherein the second inlet 1021 is disposed adjacent to the other low end 111 of the bridge 11, and wherein the second outlet 1022 is disposed adjacent to the other side of the high end 112 of the bridge 11. In order for those skilled in the art to understand the present invention, in at least one embodiment of the present invention, the lower end 111 of the bridge 11 near the second inlet 1021 of the second limiting channel 102 is defined as a second lower end 111b, and the lower end 111 of the bridge 11 near the first inlet 1011 of the first limiting channel 101 is defined as a first lower end 111a. It should be noted that, in the present invention, the first outlet 1012 is disposed at the bridge 11 between the first lower end 111a and the upper end 112. The second outlet 1022 is provided in the bridge 11 between the second lower end 111b and the upper end 112.

Preferably, when the bridge 11 is implemented in a symmetrical arc shape, the first limiting channel 101 and the second limiting channel 102 are provided at both sides of the bridge 11 symmetrical to the high end 112 of the bridge 11.

It should be noted that, in the present embodiment, the blocking device 100 for blocking blood vessels includes two locking members 20, wherein one locking member 20 is disposed at the notch 15 of the bridge 11 between the first lower end 111a and the upper end 112. The bridge 11 further defines a further notch 15 for providing a further locking member 20. The other locking member 20 is arranged in the other gap 15 of the bridge 11 between the second lower end 111a and the upper end 112. One of the locking members 20 is disposed between the first inlet 1011 and the first outlet 1012, and the other locking member 20 is disposed between the second inlet 1021 and the second outlet 1022. In order for those skilled in the art to understand the present invention, in at least one embodiment of the present invention, the locking member 20 disposed between the first inlet 1011 and the first outlet 1012 is defined as a first locking member 20a. The locking member 20 disposed between the second inlet 1021 and the second outlet 1022 is defined as a second locking member 20b, but it will be understood by those skilled in the art that the present invention is not limited thereto.

It is further noted that, in the present invention, the blocking device 100 for blocking blood vessels may be devoid of the packing 30, wherein the packing 30 may be detachably mounted to the blocking device 100 for blocking blood vessels, thereby facilitating replacement of the packing 30.

In the present embodiment, the first free end 31a of the packing 30 is implemented to pass through the second inlet 1021 of the second limiting passage 102, and the first free end 31a of the packing 30 extends from the second outlet 1022 of the second limiting passage 102 after passing through the second limiting passage 102, and the packing 30 near the second free end 31b can be pressed and fixed by the second locking member 20 b. In this way, it is furthermore possible to fix the first free end 31a of the packing 30 relatively to the bridge 11.

When the blocking device 100 for blocking a blood vessel is used to block a blood vessel to be blocked on the acting object, the first free end 31a of the tightening member 30 only needs to pass through the second limiting channel 102 and then extend out of the second outlet 1022 of the second limiting channel 102, and the tightening member 30 near the first free end 31a can be pressed and fixed by the second locking member 20 b. The fastener 30 is then secured around the corresponding site of the subject and the path of extension of the vessel to be retained at the corresponding site on the subject is allowed to lie in the opening 110 of the mount 10, while the vessel to be severed intersects the fastener 30. After the second free end 31b of the packing member 30 is then passed through the first limiting channel 101, the packing member 30, which is located near the second free end 31b, can be pressed and fixed by the first locking member 20a, and extends from the first outlet 1012 of the first limiting channel 101.

It should be noted that, after the tightening member 30 near the first free end 31a and the second free end 31b are fixed by the second locking member 20b and the first locking member 20a, the vascular retaining area 1002 and the vascular blocking area 1001 are formed, respectively. While the vessels to be preserved on the subject are correspondingly located in the vessel preserving region 1002, and the other vessels to be cut are correspondingly located in the vessel blocking region 1001.

In the present embodiment, since the second locking member 20b and the first locking member 20a, which are detachably provided to the bridge 11, are fixed near the first free end 31a and near the second free end 31b, respectively, the urging member 30 near the first free end 31a and/or near the second free end 31b can be selectively adjusted to urge the acting object by adjusting the urging member 30.

In addition, as will be appreciated by those skilled in the art, in the present invention, since the second locking member 20b and the first locking member 20a, which are detachably provided to the bridge 11, are respectively fixed near the first free end 31a and near the second free end 31b, the packing 30 can be replaced by removing the packing 30.

It should be noted that the first limiting channel 101 and the second limiting channel 102 are respectively formed between the first bridge 113 and the second bridge 114. And preferably, the first limiting channel 101 and the second limiting channel 102 are symmetrical with respect to the high end 112 of the bridge 11, respectively. In this way, after the blocking device 100 for blocking a blood vessel is applied to the acting object, the frame 10 can be symmetrically stressed, thereby improving the stability of the frame 10.

According to another aspect of the present invention, there is provided a method of blocking a blood vessel, wherein the method of blocking a blood vessel comprises the steps of:
