Problems solved by technology

[0006] 1. For vascular injury, the traditional ligation method will cause blood flow interruption, which will cause ischemic necrosis of the supplying organs, and eventually lead to complications such as multiple organ dysfunction
[0007] 2. For the intestinal tube, ligation of the intestinal tube will cause increased pressure in the intestinal cavity and intestinal dysfunction, resulting in the translocation of intestinal flora and even multiple organ dysfunction, and it will also lead to intestinal blood supply disorders and intestinal necrosis question
[0008] 3. When definite surgical anastomosis reconstruction is performed after the condition is stable, the blood vessels and intestinal tubes treated by traditional methods are prone to atrophy or delayed necrosis, which makes reconstruction difficult, or more intestinal tubes must be resected before anastomosis

Embodiment 1

[0041] Such as figure 2 , the tightening member is a tightening band 5; the wall surface of at least one side wall of the tightening band 5 is provided with a plurality of limiting teeth 6 extending along the length direction of the tightening band 5, and the profile of the limiting teeth 6 is Obtuse circular shape, several spacer teeth 6 are arranged equidistantly and a gap of the width of the spacer tooth 6 is maintained between two adjacent spacer teeth 6, so that the surface of the tightening belt 5 containing the spacer teeth 6 forms a wave shape structure;

[0042] One end of the tightening band 5 is provided with a limiting hole 7, and the limiting hole 7 is provided with a limiting protrusion that fits with the gap, so that the limiting hole 7 and the limiting tooth 6 can be engaged with each other so that the tightening band 5 can hold the blood vessel, Intestines are tightly bound.

[0043] The purpose of the wavy shape of the stop tooth 6 is to prevent the stop t...

Embodiment 2

[0045] Such as Figure 7 As shown, the tightening member is an elastic ring buckle 8 with an opening. When the opening is closed, the inner diameter of the elastic ring buckle 8 matches the outer diameter of the tightening groove. The material of the elastic ring buckle 8 is memory metal. The inner wall surface of the buckle 8 is provided with anti-slip lines. The anti-skid lines are smooth and wavy lines.

[0046] The design of the wavy anti-slip texture is to leave a gap between the elastic ring 8 and the blood vessel or intestinal tube to prevent blood vessel or intestinal tube tissue necrosis. The anti-slip texture can also increase the frictional force to prevent the elastic ring buckle 8 from slipping off. At the same time, the smooth wave-shaped texture is used to prevent the elastic ring buckle 8 from being squeezed for a long time to damage the intestines and blood vessels.

[0047] Compared with the solution in Example 1, the installation of the tightening member i...

Embodiment 3

[0049] Such as Figure 8 and Figure 9 As shown, the tightening member is a melon-shaped tightening ring 9 surrounded by nickel-titanium memory wire.

[0050] It is made of nickel-titanium memory metal material with a working temperature of 37 degrees. Before the operation, put the unused tightening ring 9 in ice water to maintain its normal shape; when in use, just place the tightening ring 9 on the part that needs to be fixed, and the body temperature will be quickly transmitted to the tightening ring 9 to make it work Then the tightening ring 9 curls along the intestinal tube or blood vessel wall to form a ring shape, and the two ends of the tightening ring 9 can form a cross memory shape, so that the tightening ring 9 tightly wraps the tube wall to achieve fixation.

[0051] Compared with Embodiment 2, this solution is more convenient and quicker, has very low requirements for surgical operations, is suitable for any ordinary medical worker, and has a good fixation effec...

Abstract

The invention relates to the field of medical apparatus, in particular to a sleeving component for emergency reconstruction of blood vessels and intestinal tubes. The sleeving component for the emergency reconstruction of blood vessels and intestinal tubes comprises a connecting cannula and a tightening piece; at least one annular tightening groove vertical to the axial direction of the connecting cannula is formed in the outer surface of the cavity wall of each of two ends of the connecting cannula; the tightening piece is matched with the tightening grooves, after the tightening piece is tightened, ends of two blood vessels or intestinal tubes are respectively connected with two ends of the connecting cannula. The sleeving component for the emergency reconstruction of blood vessels and intestinal tubes is easy, fast and convenient to operate and capable of quickly constructing a temporary blood flow or intestinal tract passage.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sleeve assembly for emergency reconstruction of blood vessels and intestines. Background technique [0002] As we all know, a variety of situations can cause the rupture or perforation of blood vessels or intestinal tubes in the thoracic and abdominal cavity, such as when soldiers on the battlefield are injured by bullets in the thoracic and abdominal cavity, or in patients with serious car accidents that cause thoracic and abdominal cavity injuries, or sudden events such as earthquakes Such as the casualties of similar natural disasters and so on. [0003] The scenarios listed above have several common features: 1. They are all emergencies, and the situation is urgent, which cannot be predicted and prepared in advance; 2. The critical condition requires immediate surgical intervention to save lives; 3. Injury Within 72 hours, the condition was repeatedly unpredictable and accom...
