[0027] Embodiment
[0028] As Figures 1-6 shown, a vascular anastomosis device for convenient docking proposed by the present utility model includes a pair of blood vessels 1 and an anastomosis device body 2 provided at the connecting end of the blood vessels 1. A support tightening hoop 3 is fixedly connected to the outer wall of the anastomosis device body 2, and a support mechanism for generating a gap for the blood vessel 1 to pass through is provided between the anastomosis device body 2. It further includes: inserting tubes 21 sleeved on both ends of the anastomosis device body 2 and the blood vessels 1. The diameter of the end of the inserting tube 21 away from the anastomosis device body 2 is slightly smaller than the diameter of the blood vessel 1, which is used to facilitate the sleeving of the blood vessel 1 on the anastomosis device body 2; a pair of tightening hoops 3, and a plurality of conical thorns 31 distributed in a circumferential array are fixedly connected to the inner wall of the tightening hoop 3. The function of the conical thorns 31 is to insert into the blood vessel 1 and then increase the friction between the blood vessel and the tightening hoop 3. The tightening hoop 3 is sleeved on the anastomosis device body 2, and a tightening mechanism for tightening the blood vessels 1 at both ends of the anastomosis device body 2 is provided on the tightening hoop 3; a reverse prevention mechanism rotatably installed at one end of the tightening hoop 3 for restricting the loosening of the tightening mechanism. When the elastic rack 321 needs to be disengaged from the second convex head 33, the reverse prevention mechanism makes it impossible to disengage. Only by pulling the pull ring 335 to drive the connecting rope 334 to move, the connecting rope 334 drives the rotating block 332 to rotate through the support of the U-shaped rotating seat 331, and then the U-shaped rotating seat 331 cannot block the elastic rack 321, and only then can the elastic rack 321 be pulled out from the second convex head 33.
[0029] Furthermore, the tightening mechanism includes a first convex head 32 and a second convex head 33 fixedly connected to both ends of the tightening hoop 3. Second insertion holes 336 and rotating blocks 332 for inserting the tips of surgical forceps are provided at the opposite ends of the first convex head 32 and the second convex head 33. An elastic rack 321 is fixedly connected to one end of the first convex head 32 facing the second convex head 33. The second convex head 33 is movably sleeved with the elastic rack 321. A rotating block 332 that does not prevent the insertion of the elastic rack 321 and is used to restrict the elastic rack 321 from disengaging from the second convex head 33 is provided inside the second convex head 33. A connecting rope 334 fixedly connected to the rotating block 332 has one end movably passing through the second convex head 33. A pull ring 335 is fixedly connected to the end of the connecting rope 334 away from the rotating block 332.
[0030] Among them, the anti-reverse mechanism includes a U-shaped rotating seat 331 fixedly connected inside the second convex head 33. The U-shaped rotating seat 331 is rotatably connected to the rotating clamping block 332. A return spring 333 is arranged inside the second convex head 33. The function of the return spring 333 is to push the rotating clamping block 332 to always clamp the elastic rack 321, so as to prevent the tightened tightening hoop 3 from suddenly loosening. One end of the return spring 333 is fixedly connected to the inner wall of the second convex head 33, and the other end of the return spring 333 is fixedly connected to the rotating clamping block 332.
[0031] Furthermore, the support mechanism includes a first support rod 4 and a second support rod 5. The first support rod 4 and the second support rod 5 are used to create a gap for the blood vessel 1 to pass through between the tightening hoop 3 and the stapler body 2. The first support rod 4 is fixedly connected to the second support rod 5. A pair of connection point blocks 451 are fixedly connected to both ends of the first support rod 4. A plurality of connection point blocks 451 are fixedly connected to the end of the first support rod 4 away from the second support rod 5. The function of the connection point blocks 451 is to easily break the connection between the first support rod 4 and the second support rod 5 and the tightening hoop 3 and the stapler body 2 with a little force when necessary. After breaking, the connection point blocks 451 will be on the first support rod 4 and the second support rod 5. And the material of the connection point blocks 451 is silicone. The connection point blocks 451 on the second support rod 5 are fixedly connected to the stapler body 2, and the connection point blocks 451 on the first support rod 4 are fixedly connected to the corresponding second convex head 33.
[0032] In this embodiment, when a vascular stapler that is convenient for docking is needed, such as Figure 1As shown, the opposite ends of a pair of blood vessels 1 are sleeved on the intubation tubes 21 at both ends of the stapler body 2. Then, one end of the pair of blood vessels 1 is passed through the gap between the tightening hoop 3 and the stapler body 2 and abuts against the second support rod 5. At this time, through the connection point blocks 451 provided on the first support rod 4 and the second support rod 5, the first support rod 4 and the second support rod 5 are shaken, so that the connection point blocks 451 on the first support rod 4 and the second support rod 5 are disengaged from the second convex head 33 and the stapler body 2, and the first support rod 4 and the second support rod 5 are discarded. Since the second support rod 5 on the stapler body 2 cannot hold the connection of the pair of blood vessels 1, the pair of blood vessels 1 can be sleeved on the intubation tubes 21 on the stapler body 2 and connected. Then, use pliers to insert one tip into the first jack 322 on the first convex head 32, and then insert the other tip of the pliers into the second jack 336 on the second convex head 33, and clamp the pliers. Finally, the first convex head 32 and the second convex head 33 are moved closer together, and the first convex head 32 drives the elastic rack 321 to insert into the second convex head 33, and the rotating locking block 332 in rotation is used to lock so that the elastic rack 321 cannot escape. Furthermore, the first convex head 32 and the second convex head 33 drive the tightening hoop 3 to tighten. After tightening, the tightening hoop 3 will first tie up the blood vessels 1 and be clamped in the card slot 22 on the stapler body 2. By inserting the conical spikes 31 provided on the inner wall of the tightening hoop 3 into the blood vessels 1, the pair of blood vessels 1 cannot be easily detached from the stapler body 2, which is convenient and easy to operate.
