According to one example, theanastomotic auxiliary 450 is flexible. In some examples, theanastomotic auxiliary 450 may contain a liquid or a fluid (such as buffered saline) or a gas. Theanastomotic auxiliary 450 may be formed of an elastomer (such as balloon, silica gel containing liquid and/or gas, which cannot be broken easily), or may be the solid elastomer (such as silica gel) or shape memory metal (nickel-titanium alloy), but not limited to this. -
FIGS. 5A, 5B andFIGS. 6A-6E describe exemplary anastomotic auxiliary 550A, 550B, and 650. As shown in the example ofFIG. 5A , the interior of anastomotic auxiliary 550A may be hollow. The anastomotic auxiliary 550A may be deformable, which may facilitate embedding the anastomotic auxiliary 550A into the target to be anastomosed or withdraw from it. The anastomotic auxiliary 550A has theexit part 552A (in some examples, the anastomoticauxiliary exit part 552A may be a line), user may remove the anastomotic auxiliary 550A from the target to be anastomosed by pulling theexit part 552A. In some examples, the anastomotic auxiliary 550A is closed, and its internal gas or liquid cannot be supplemented or released at any time. In other examples, the anastomotic auxiliary 550A may have an opening-closing hole or a valve, so that user may supplement or release the gas or liquid inside the anastomotic auxiliary 550A through an opening-closing hole or valve at any time. For example, before embedding the anastomotic auxiliary 550A into the target to be anastomosed, user may release some of the gas or liquid inside the anastomotic auxiliary 550A through the opening-closing hole or valve first, and then supplement the gas or liquid inside the anastomotic auxiliary 550A through the opening-closing hole or valve after embedding. Before removing the anastomotic auxiliary 550A from the target to be anastomosed, the user may release the gas or liquid inside the anastomotic auxiliary 550A through the opening-closing hole first or valve. It should be understood that the anastomoticauxiliary exit part 552A may not only be situated or located in the middle of anastomotic auxiliary 550A, it may alternatively be located anywhere the anastomotic auxiliary 550A as needed; for example, the anastomoticauxiliary exit part 552A may be set at the end of anastomotic auxiliary 550A. - Turning to
FIG. 5B , the anastomotic auxiliary 550B includes a firstfusiform half 551B and a secondfusiform half 553B. A firstjoint surface 555B of the first fusiform half 551 and the secondjoint surface 557B of the secondfusiform half 553B cooperatively form a fixing mechanism to prevent firstfusiform half 551B and secondfusiform half 553B from mutual slipping after embedding into the target to be anastomosed. In some examples, the firstfusiform half 551B and secondfusiform half 553B have theexit part fusiform half 551B and secondfusiform half 553B from the target to be anastomosed by pulling theexit parts concave portions convex portions joint surface 555B and secondjoint surface 557B respectively. Theconvex portion 562B andconcave portion 566B are mutually matched whilst the convex 564B and concave 568B are mutually matched. In some examples, the fixing mechanism is the slight viscosity at the firstjoint surface 555B and secondjoint surface 557B. It should be noted that,FIG. 5B is only an example, the anastomotic auxiliary need not only comprise of two fusiform halves, it may include any number of fusiform halves (or fusiform components) as needed. Besides, the first fusiformhalf exit part 552B and second fusiformhalf exit part 554B may not only be set in the middle of the firstfusiform half 551B and secondfusiform half 553B respectively, they may be set at anywhere of firstfusiform half 551B and secondfusiform half 553B respectively as needed; for example, they may be set at the end of the firstfusiform half 551B and secondfusiform half 553B respectively. - As shown in the embodiments from
FIGS. 6A-6E , theanastomotic auxiliary 650 comprises of plural lines and has the removableauxiliary control units anastomotic auxiliary 650 has been embedded into the target to be anastomosed, the user may control the interval (spacing) between theauxiliary control units auxiliary control units auxiliary control units anastomotic auxiliary 650 before removing the anastomotic auxiliary 650 from the target to be anastomosed. Theremoval device 674 of anastomoticauxiliary removal aid 670 may be used to fix theanastomotic auxiliary 650. In some examples, theremoval device 674 may be connected to theanastomotic auxiliary 650 before embedding the anastomotic auxiliary into the target to be anastomosed. Theremoval device 674 may be removed from thehollow tube 672 to advance (drive) the anastomotic auxiliary 650 into thehollow tube 672. - Referring to
FIG. 6E , thehollow tube 672 has an access (cutout, port), and theremoval device 674 is at least partially housed within thehollow tube 672. In some examples, the tube diameter of thefront end 672A ofhollow tube 672 is slightly smaller than the pore diameter of the un-anastomosed gap to be anastomosed. Using a slightly smaller diameter of thefront end 672A ofhollow tube 672 can avoid the anastomotic auxiliary from enlarging the pore diameter of un-anastomosed gap. In other examples, the tube diameter of thefront end 672A ofhollow tube 672 substantially equals to the pore diameter of the un-anastomosed gap, or is only slightly larger than the pore diameter of the un-anastomosed gap. - Referring once again to
FIGS. 4A-4H , thefirst telescoping part 423 may be used for extending toward the first end to be anastomosed 910, and thesecond telescoping part 433 may be used for extending toward the second end to be anastomosed 920. In some examples, thefirst manipulator 420 has a first exit part, and thesecond manipulator 430 has a second exit part. After the target to be anastomosed 900 has been anastomosed, thefirst manipulator 420 can be removed from the target to be anastomosed 900 through the first exit part, and thesecond manipulator 430 can be removed from the target to be anastomosed 900 through the second exit part. In some examples, the first exit part is the gap at thefirst telescoping part 423, and the second exit part is the gap at thesecond telescoping part 433. In some examples, the structure of thefirst manipulator 423 andsecond manipulator 433 may be as shown fromFIG. 2A toFIG. 2D . - Referring to
FIG. 4A , when using the anastomosis set 400, telescope thefirst telescoping part 423 of thefirst manipulator 420 toward the first end to be anastomosed 910, and then make one end of anastomotic auxiliary 450 enter from the first end to be anastomosed 910. Then, as shown inFIG. 4B , make another end of anastomotic auxiliary 450 enter from the second end to be anastomosed 920. - Referring to
FIG. 4C , after another end of the anastomotic auxiliary has entered from the second end to be anastomosed 920 through the second exit part of thesecond manipulator 430, telescope thesecond telescoping part 433 of thesecond manipulator 430 to the second end to be anastomosed 920. Referring toFIGS. 4D and 4E , the first end to be anastomosed 910 and second end to be anastomosed 920 are approximated and aligned by approximating thefirst manipulator 420 and thesecond manipulator 430. In one example, the proximal ends of the first andsecond manipulator FIGS. 1A-1D , which may assist the proceeding of anastomosis. In some examples, thefirst telescoping part 423 is advanced (extended, telescoped) toward the first end to be anastomosed 910, thefirst end 910 should be folded, and thesecond telescoping part 433 is advanced (extended, telescoped) to the second end to be anastomosed 920 and end 920 should be folded. In this way, it can avoid the target to be anastomosed 900 from slipping from thefirst telescoping part 423 orsecond telescoping part 433. - Referring to
FIG. 4F , after thefirst end 910 andsecond end 920 of the target to be anastomosed 900 have been mutually aligned to each other, use theanastomosis mechanism 440 to anastomose thefirst end 910 with thesecond end 920. The anastomosis mechanism and its method may be as described above with reference toFIGS. 3A-3E . It should be noted that, when using the anastomosis mechanism to anastomose thefirst end 910 with thesecond end 920 of the target to be anastomosed 900, a certain gap between thefirst end 910 and thesecond end 920 needs to be reserved. In other words, total or complete anastomosis is not necessary. - Referring to
FIG. 4G , after using the anastomosis mechanism to anastomosed thefirst end 910 with thesecond end 920, theanastomotic auxiliary 450 is removed from the anastomosed gap by pushing the anastomoticauxiliary exit part 452, Finally, inFIG. 4H ,makeup mechanism 460 is used to make up (complete) the un-anastomosed gap. In different specific embodiments, the makeup mechanism may be, but not limited to, suture mechanism, bonding mechanism, buckling mechanism, clamping mechanism and nailing mechanism etc. - According to one example,

In this way, after the first end to be anastomosed 910 and second end to be anastomosed 920 have been mutually aligned to each other, or when using theanastomosis mechanism 440 to anastomose thefirst end 910 with thesecond end 920, let the body fluids (e.g., Blood) flow in the hollow tube of anastomotic auxiliary 450, so as to shorten the time of non-flowing body fluids. - Referring to
FIGS. 7A and 7B , theanastomotic aid device 710 includes amain body 712, a firstmobile part 714 and a secondmobile part 716. The firstmobile part 714 and secondmobile part 716 can move on (relative to) themain body 712 laterally. Among them, the firstmobile part 714 connects to the first manipulator 723, and the secondmobile part 716 connects to thesecond manipulator 730. Thus, the user can move the firstmobile part 714 and secondmobile part 716 on the main body laterally to assist in anastomosing the target to be anastomosed 900. According to one example, the length ofmain body 712 is greater than the length ofanastomotic auxiliary 750.
