Benefits of technology

In this patented technology, there're certain technical feature improvements over existing methods such as manually measuring blood vessel positions or attaching clamps onto branches during healing procedures. These new techniques have improved precision but require multiple workers who must collaboratively operate them separately compared against each other. Additionally, these techniques may result in bleeding if they don’t completely seal up their own holes before being connected together again. Therefore, it would make better ways to reconstruct tissue around damaged areas without having to repeatedly measure its size and shape.

Problems solved by technology

This patented technical solution described in this patents describes how it helps surgeons perform procedures on patients who may be candidates for organ transplants without having major complications such as bleeding from puncture wounds caused by small biliary stones that block off flow into arteries supplying oxygenated blood to organs like kidneys called ureters (urinary bladder). Current methods involve cutting openings through large areas of tissue around duodenum catheters inserted via femoral artery leads to potential complication rates due to lacking accurate tools needed for complete replacement.

specific Embodiment approach 1

[0040] An artificial blood vessel reconstruction device for liver transplantation according to this embodiment, such as Figure 1-24 As shown, its composition includes a support member 1, a rotating member 2, and a sliding cutting member 3. The supporting member 1 is located at the bottom of the whole mechanism as a supporting structure. 3 is inserted on the rotating member 2;

[0041] in,

[0042] The supporting member 2 includes a connecting bolt 2a, a supporting end cover 2b, an outer supporting cylinder 2c, and an inner supporting cylinder 2d;

[0043] The inner support cylinder 2d is set in the outer support cylinder 2c, and the two ends of the inner support cylinder 2d and the outer support cylinder 2c are each equipped with a support end cap 2b, and the two support end caps 2b are respectively fixed to the inner support by 8 connecting bolts 2a The two ends of the cylinder 2d and the outer support cylinder 2c; a group of outer cylinder chute long holes 2c2 are arrange...

specific Embodiment approach 2

[0046]The difference from Embodiment 1 is that the artificial blood vessel reconstruction device for liver transplantation in this embodiment, such as Figure 1-24 As shown, the support member 1 also includes a machine foot 1a, a bottom fixing plate 1b, a support frame 1c, and a fastening bolt 1d;

[0047] The lower surface of the bottom fixed plate 1b is fixed with four machine feet 1a, and the upper surface of the bottom fixed plate 1b is fixed with a support frame 1c; the support frame 1c is respectively provided with a support plate 1c1 on both sides, and a fastening plate 1c1 is provided on the support plate 1c1. Hole 1c2 and rotation hole 1c3, fastening hole 1c2 is provided with internal thread, two fastening bolts 1d are respectively installed in the fastening holes 1c2 of support plates 1c1 on both sides of support frame 1c, fastening bolts 1d and fastening holes 1c2 Connected by thread structure.

specific Embodiment approach 3

[0049] The difference from Embodiment 1 or Embodiment 2 is that an artificial blood vessel reconstruction device for liver transplantation in this embodiment, such as Figure 1-24 As shown, the support end cover 2b also includes a support shaft 2b1, a support sleeve 2b2, an end cover bolt hole 2b3, and an end cover fastening ring 2b4;

[0050] One side of the end cover fastening ring 2b4 is connected with a support shaft 2b1, and the other side of the end cover fastening ring 2b4 is connected with a support sleeve 2b2, and four end cover bolt holes 2b3 are evenly distributed in the circumferential position of the end of the support sleeve 2b2 , There is a threaded structure in the bolt hole 2b3 of the end cover.

[0051] The support end cover 2b is installed in the rotation hole 1c3 of the support frame 1c, and the support shaft 2b1 is in clearance fit with the rotation hole 1c3, so that the support end cover 2b can rotate circumferentially in the rotation hole 1c3 of the supp...

Abstract

The invention relates to a liver transplantation artificial blood vessel reconstruction device, and belongs to the field of medical devices. An existing technique of anastomosing hepatic vessels and artificial vessels involved in the reconstruction of hepatic vein is not perfect. According to the liver transplantation artificial blood vessel reconstruction device, a supporting member (1) is located at the bottom of a whole mechanism as the supporting structure, rotating members (2) are installed on two supporting frames (1c) of the supporting member (1), and sliding cutting members (3) are installed on the rotating members (2) in an inserted mode. With the aid of the liver transplantation artificial blood vessel reconstruction device, the positioning opening and suture operation of artificial blood vessels can be completed quickly, the efficiency and accuracy are greatly improved, the risk of internal leakage is avoided, and the suture operation of the artificial blood vessels can be completed by a single person.
