Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a two-end clamping type blood vessel anastomosis device.
Background
The vascular anastomosis reconstruction has important value and significance for restoring organ functions, and the vascular anastomosis operation is the most common and important basic operation in modern surgical operations. The rapid vascular anastomosis technology is more important in the operations of organ transplantation, tumor invasion and vascular excision reconstruction and the like.
At present, there are two main clinical methods of vascular anastomosis: the traditional suture anastomosis method (manual suture) and the anastomosis method of the vascular anastomosis instrument. To date, manual suturing remains the most clinically fundamental and most commonly used method of vascular anastomosis. The skill requirement of an operator is high, and even a doctor with good surgical technique and a plurality of times of surgical training for a long time needs 5 to 30 minutes for manually anastomosing each anastomotic stoma. When the number of blood vessels needing to be anastomosed in the operation is large, the operation time is longer. Some vascular anastomoses need to be performed under extracorporeal circulation, which can cause great negative effects to patients for a long time. Even if extracorporeal circulation assistance is not required, prolonged anesthesia and surgery can cause significant shock to the patient. On the other hand, the long-time vascular anastomosis can cause the operator to be very tired, the error rate of vascular anastomosis is increased when the body of the operator is tired and the mood of the operator is irritated, and the operation risk is increased. In some procedures, vascular anastomosis can compete for seconds. For example, in organ transplantation, the ischemia time of donor organ cannot be too long, the operation takes seconds, and the length of the operation is closely related to the healing time. With conventional manual suturing, even after intensive training of the suturing technique is performed on the surgeon, it is still difficult to significantly reduce the operation time. The transmission manual suture vascular anastomosis operation has the advantages of high operation difficulty and low efficiency, and the anastomosis precision and reliability of the operation are difficult to effectively guarantee.
With the development of the manufacturing process of medical instruments and the emergence of new materials, the anastomosis technology of the vascular anastomat is developed rapidly. Various vascular anastomoses appear in succession, the common structure of the vascular anastomoses is a needle ring structure, and the 73-2 type vascular anastomoses is taken as a representative, so that great convenience is brought to clinic, but metal foreign bodies remain in the body, and the examination of nuclear magnetic resonance of a patient later is influenced. Since the Chinese patent ZL 201310111076.7 discloses a large blood vessel anastomat, the large blood vessel anastomat adopts a fixing mode of a clamp body and a tooth buckle, although the structure is relatively simple, the accuracy of an operation position is low, particularly the attaching degree of an anastomotic blood vessel is difficult to ensure, the accuracy of an anastomotic angle and the position of the blood vessel cannot be ensured, and the difficulty of disassembly and assembly after operation is also high. For example, the blood vessel anastomat of chinese patent application No. 201710434374.8 has a complex structure, and when a blood vessel B is inserted into a blood vessel a, it is used for blood vessels of different calibers, which is likely to cause thrombosis risk. And the vascular anastomosis device with other structures has a common and complex structure and is inconvenient to operate.

a two-end clamp-on vascular anastomosis device, comprising:
the anastomosis ring I1 is cylindrical, referring to fig. 1 and 2, a plurality of convex bodies I2 are arranged on the outer side face of one end of the anastomosis ring I, and a circle of outward concave-convex phase body I7 is arranged on the outer edge of the other end of the anastomosis ring I;
the anastomosis ring II 4 is identical to the anastomosis ring I1 in shape and size, referring to figures 3 and 4, a plurality of convex bodies II 6 are arranged on the outer side face of one end of the anastomosis ring II, a circle of outward concave-convex intermediate body II 8 is arranged on the outer edge of the other end of the anastomosis ring II, and one end of the anastomosis ring II 4 with the convex bodies II 6 is involuted with one end of the anastomosis ring I1 with the convex bodies I2;
the drawing belt 9, referring to fig. 3, is of an i-shaped structure, and has a plurality of effective lengths (i.e. the length of the middle axis of the i-shaped structure) equal to or slightly greater than the total length of the anastomosis ring 1+ the anastomosis ring two 4, one end of the drawing belt is clamped on the concave-convex intermediate body I7, and the other end of the drawing belt is clamped on the concave-convex intermediate body II 8, so that the anastomosis ring 1 and the anastomosis ring two 4 are fastened.
In further embodiments of the present invention, the side of the anastomosis ring 1 has a first recess 3 for facilitating clamping by hemostats, and the side of the anastomosis ring 4 has a second recess 5 for facilitating clamping by hemostats.
In further embodiments of the present invention, the first protrusions 2 and the second protrusions 6 are both of smooth-ended oblique-barbed structures, and have a plurality of rows and columns, the first protrusions 2 are divergent from the first anastomosis ring 1 to the other end along the ends thereof, and the second protrusions 6 are divergent from the second anastomosis ring 4 to the other end along the ends thereof.
According to the structure, the working process of the invention is as follows:
clamping the first concave part 3 of the anastomosis ring I1 by a hemostatic forceps, sleeving the broken end of the blood vessel on one side, turning the broken end of the blood vessel outwards and hanging the broken end of the blood vessel on the first convex body 2, clamping the second concave part 5 of the anastomosis ring II 4 by the hemostatic forceps in the same way, sleeving the broken end of the blood vessel on the other side, and turning the broken end of the blood vessel outwards and hanging the broken end of the blood vessel on the second convex body 6.
The vascular occlusion clamps or the occlusion pincers at the two ends are loosened to ensure that no thrombus or gas exists, the anastomosis ring I1 and the anastomosis ring II 4 are involuted, then the two ends of each I-shaped traction belt 9 are respectively clamped on the concave-convex phase body I7 and the concave-convex phase body II 8, after clamping, no blood seeps out from a gap between the anastomosis ring I1 and the anastomosis ring II 4, and the vascular anastomosis is finished.
Further, an auxiliary oblique spine may be disposed on the outer side surface of the first convex body 2 and/or the second convex body 6, as shown in fig. 3, the auxiliary oblique spine is inclined in the same direction as the first convex body 2 or the second convex body 6, but the angle between the auxiliary oblique spine and the anastomotic ring is larger than the angle between the first convex body 2 or the second convex body 6 and the anastomotic ring, for example, the angle between the auxiliary oblique spine and the first convex body 2 or the second convex body 6 may be 15 °. The purpose of arranging the auxiliary oblique stabs is to ensure that when the broken end of the blood vessel is outwards turned to be hung on the first convex body 2 or the second convex body 6, once the broken blood vessel falls off from the first convex body 2 or the second convex body 6, the auxiliary oblique stabs play a role in secondary fixation, namely, the broken end of the fallen blood vessel can be blocked by the auxiliary oblique stabs, so that the falling is prevented, and the outwards turning fixation performance of the blood vessel is enhanced.
The vascular anastomosis device is made of degradable high polymer materials or biodegradable chitosan or magnesium alloy, is kept in a body for a certain time, and is degraded after the vascular anastomosis opening is completely healed, so that no foreign matters are left in the body.
