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 ev

Example Embodiment

[0040] Example 1:

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

[0042] One end of the tightening band 5 is provided with a limiting hole 7, and a limiting protrusion matched with the gap is arranged in the limiting hole 7 so that the limiting hole 7 and the limiting tooth 6 can be engaged with each other to enable the tightening band 5 to protect blood vessels, The bowel is tight.

[0043] The shape of the limiting tooth 6 is wavy to prevent the limiting tooth 6 from piercing the wall of ...

Example Embodiment

[0044] Example 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 of the buckle 8 is provided with anti-slip lines. The anti-skid lines are smooth and wavy lines.

[0046] The wavy anti-slip lines are designed to leave a gap between the elastic ring buckle 8 and the blood vessel or intestine to prevent the blood vessel or intestinal tissue from becoming necrotic. The anti-skid pattern can also increase friction to prevent the elastic ring buckle 8 from slipping off, and the smooth wavy pattern 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 Embodiment 1, the tightening member in this solution is more convenient an...

Example Embodiment

[0048] Example 3:

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

[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 using it, only need to place the tightening ring 9 on the part that needs to be fixed, and the body temperature is quickly transmitted to the tightening ring 9 to make it work Then the tightening ring 9 curls along the wall of the intestine or blood vessel 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 extremely low requirements for surgical operations, is suitable for any ordinary medical workers, an...

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...
