Specifically, the mantle 1 and the elastic support body 5 are both made of materials meeting medical standards, the mantle 1 is made of a medical film with certain flexibility, the mantle 1 can form a support body supporting the cavity after being supported by the elastic support body 5, the elastic support body 5 is attached to the inner wall of the mantle 1, the shape of the elastic support body 5 in the mantle 1 is consistent with that of the mantle 1, and the elastic support ring 5 is spiral in the mantle 1 as shown in fig. 2. The elastic support ring 5 can be made of plastic elastomer and the like, after the support body is formed by matching the elastic support ring 5 and the mantle 1, the support body can have certain hardness, and traction deformation can be realized.
In the embodiment of the invention, the formed support body is internally provided with a supporting and flowing cavity 6, the two ends of the support body are provided with the guide heads 3, namely, the support body is in a tubular or similar tubular structure, the outer diameter of the guide heads 3 formed at the two ends of the support body is larger than that of the middle part of the support body, so that the suture groove 7 is formed at the middle position of the support body, when the support body is respectively placed into two broken cavities through the guide heads 3, the cavities can be sutured conveniently by utilizing the suture groove 7, and in the specific implementation, the cavities to be sutured can be arterioles or other organs. All set up liquid flow mouth 4 at the both ends of supporter, liquid flow mouth 4 can be linked together with supporting circulation cavity 6 to when putting into the supporter and treating sutural chamber say, can form the pipeline that allows the liquid circulation through the supporter, if when sewing up the arteriole, the blood in the arteriole can realize the normal flow of blood through liquid flow mouth 4, supporting circulation cavity 6.
Further, both ends of the elastic support ring 5 penetrate out of the middle region of the mantle 1 to form a pulling line 2 for pulling the support body.
In the embodiment of the invention, when the support body needs to be separated from the sewed cavity channel and the sewed cavity channel is not affected, the support body generally needs to be pulled. In order to realize the traction of the support body and the deformation of the support body, two ends of the elastic support ring 5 can penetrate out of the middle area of the mantle 1, and two ends of the elastic support ring 5 are located on the same side of the mantle 1 and are adjacent to each other, that is, the traction line 2 is located in the middle area of the support body. When the elastic support ring 5 is pulled by the pulling line 2, the elastic support ring 5 can be deformed, so that the structural shape of the whole support body is damaged, when the elastic support ring 5 is deformed and separated from the mantle 1, the mantle 1 is in a film shape, and when the pulling line 2 is continuously pulled, the mantle 1 can be separated from a cavity channel which is partially sewed along with the elastic support ring 5.
In specific implementation, the elastic support ring 5 is formed by an elastic support body spirally arranged in the outer sleeve film 1, and two ends of the elastic support body form corresponding pulling lines 2. As shown in fig. 2, the elastic support ring 5 comprises two spiral bodies 9 corresponding to the two traction wires 2, the traction wires 2 are connected with the corresponding spiral bodies 9 through traction spiral connecting bodies 8, and the traction spiral connecting bodies 8 cross the corresponding spiral bodies 9; for any spiral body 9, the spiral direction of the spiral body 9 is a spiral in the direction that the end of the mantle 1 points to the center of the mantle 1.
In the embodiment of the invention, the traction wire 2 and the traction spiral connecting body 8 are both non-spiral parts, the elastic support ring 5 comprises two spiral bodies 9 with different spiral directions, the two spiral bodies 9 form a main body of the elastic support ring 5, the length of the two spiral bodies 9 is matched with that of the mantle 1, and the length of one spiral body 9 can be approximately equal to half of that of the mantle 1. The traction spiral connecting body 8, the traction line 2 and the spiral body 9 can adopt an integrated structure, the traction spiral connecting body 8, the traction line 2 and the spiral body 9 are in one-to-one correspondence, and after the two spiral bodies 9 are connected, the joint part of the traction spiral connecting body 8 and the spiral body 9 is positioned on the outer side of the spiral body 9, namely the end part of the mantle 1 and the outer side of the joint part of the two spiral bodies 9. After the traction spiral connecting bodies 8 are connected with the corresponding spiral bodies 9, the traction spiral connecting bodies cross the connected spiral bodies 9, the other ends of the traction spiral connecting bodies 8 are connected with the corresponding traction wires 2, and the traction wires 2 penetrate out of the mantle 1. In the outer mantle 1, two spiral bodies 9 respectively correspond to the end parts of the outer mantle 1; for any spiral body 9, the spiral direction of the spiral body 9 is a spiral in the direction that the end of the mantle 1 points to the center of the mantle 1.
In addition, when the corresponding traction line 2 is pulled, the thread body 9 connected with the traction line 2 can be in a loosening and disassembling state, and when the thread body 9 is loosened and disassembled, the thread body 9 is gradually disassembled from the end part of the mantle 1 to the center direction of the mantle 1;
after the spiral body 9 is disintegrated and is pulled by the corresponding pulling line 2, the pulling spiral connecting body 8 and the spiral body 9 are pulled out from the middle area of the mantle 1 along with the pulling of the corresponding pulling line 2, and in the pulling process, the mantle 1 can be pulled out from the implantation cavity after being deformed.
In the embodiment of the present invention, as can be seen from the above description of the spiral body 9, the pulling spiral connector 8 and the pulling line 2, when the corresponding pulling line 2 is pulled, the spiral body 9 correspondingly connected can be loosened and disassembled by pulling the spiral connector 8, specifically, the loosening and disassembling means that the spiral body 9 is changed from a spiral state to a linear stretching state, the spiral body 9 is in the spiral state and mainly can be adapted to the mantle 1, so as to support the mantle 1, and after the spiral body 9 is loosened and disassembled, the support of the spiral body 9 to the mantle 1 is convenient to remove, and after the support of the mantle 1 by the spiral body 9 is removed, the mantle 1 can be in a shrinkage deformation state.
For any spiral body 9, the spiral direction of the spiral body 9 is a spiral in the direction from the end of the mantle 1 to the center of the mantle 1, so that when the spiral body 9 is pulled by the pulling wire 2, the spiral body 9 is gradually disassembled from the end of the mantle 1 to the center of the mantle 1, and at this time, the spiral body 9 is not knotted in the mantle 1, and the mantle 1 is not influenced to be pulled out from the cavity channel.
Further, the guide head 3 is tapered at the end of the support body. In the embodiment of the invention, the outer diameter of the guide head 3 is gradually reduced from the suture groove 7 to the direction of the guide head 3, and the end part of the support body can be conveniently placed in a cavity to be sutured by utilizing the conical guide head 3.
When the support is used specifically, two ends of the support body are respectively placed into the cavity channel to be sutured through the guide head 3, after the cavity channel is supported through the support body and the guide head 3, the cavity channel is sutured by using the existing common arteriolar suturing method, before the cavity channel is sutured, the support body is drawn by using the drawing line 2, after the drawing line 2 is drawn, the elastic support ring 5 deforms, and therefore the elastic support ring 5 and the mantle 1 can be drawn out from the partially sutured cavity channel. Because most of the cavity channels are sutured and connected, after the support body is pulled out from the small artery, the subsequent suturing operation of the cavity channels can still be met, namely the separation of the support body and part of the sutured cavity channels is conveniently realized, and the normal state of the sutured cavity channels is not influenced.
