Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a liver vascular blocking device for trauma emergency treatment.
Background
The liver is the largest solid organ in the body, and is supplied by artery and portal vein, so that the blood supply is very rich, and the liver is soft and fragile and is easy to break in abdominal trauma. Many abdominal traumas occur in remote areas such as mountain falls, scenic accidents, outdoor adventure, public transportation accidents, and the like. At this time, hospitals should be selected nearby for emergency treatment, typically hospitals in county and village or district level cities.
When a severely wounded person arrives at a hospital, medical staff firstly performs image examination such as CT and the like to judge wounded and bleeding parts, then performs laparotomy exploration and hemostasis operation, and observes the conditions of all organs of the viscera. Specifically, if the viscera is damaged by the spleen, the gall bladder, the unilateral kidney, or the intestinal canal of a part of sections and other resectable organs, the medical level of the primary hospital can complete the direct resection of the organs, so as to achieve the purposes of rapid and exact hemostasis and life saving. The liver is a single organ responsible for multiple functions such as coagulation substance synthesis, lipid metabolism, glycometabolism, poison metabolism, etc., and when severe and complex rupture injury occurs, hemostasis cannot be performed at the cost of cutting off the whole organ. At this time, the liver is hemostatic, the severity of liver injury and the damaged blood vessel are required to be judged by the conditions of the size, the position, the depth, the bleeding color, the bleeding flow rate and the like of the hepatic rupture wound, and the following operation modes are reasonably selected: such as liver split repair, liver segment resection, liver lobe resection and even liver great vessel reconstruction. The rapid judgment of injury, reasonable planning of surgery and implementation of liver problematic surgery requires a lot of liver surgery experience. If the basic emergency medical facility does not complete the technical accumulation of the above procedure, it is often necessary to close the abdominal cavity after proper control of liver bleeding and then to transport to a higher level hospital.
The most widely used method for controlling liver blood flow is the Pringle method, i.e. intermittent blocking of blood flow from whole liver into liver vessels. The method uses finger or liver belt to tighten the blood vessel of liver, and controls blood supply of hepatic artery and portal vein. However, long-time blockage tends to cause necrosis of the liver, and therefore, it is necessary to loosen the liver for 5 minutes after 15-30 minutes of blockage, to allow the liver to briefly resume blood flow, and then to perform the next blockage period. Liver blood flow blockage by the Pringle method is usually performed under general anesthesia surgical conditions. During transportation of a patient with liver trauma, the abdominal cavity is closed, and no sterile general anesthesia operation condition exists in an ambulance during transportation. Therefore, the Pringle liver blood flow blocking method is effective but is used only in liver partial resection operation of general anesthesia. The method can not be applied in the transportation process of hepatic rupture injury, and most of the method can only be used for stopping bleeding by compression of a wound surface of the liver by gauze, and as the gauze filling method has poor blocking and inaccurate hemostatic effects compared with the Pringle method, the method has great vascular injury to the wound surface of the liver and is easy to cause abdominal infection. If a device were available that would allow a physician to intermittently block hepatic blood flow to the liver during the delivery of the patient, it would be helpful to increase the overall survival rate of patients with complex liver trauma.

The practicability is strong.
It should be noted that the initial position of the movable clamp 32 is set as the hinge. I.e. the lowest limit point is the horizontal position where the hinge is located. A supporting spring with a certain supporting force is arranged at the bottom of the movable clamp head 32, and the top of the supporting spring is movably connected with the bottom surface of the movable clamp head 32, so that the movable clamp head 32 is only supported to limit the lowest limit point, and the upward sliding of the movable clamp head 32 is not influenced. Of course, besides the supporting spring, a gap is reserved between the bottom of the movable chuck 32 and the base 11, that is, two mutually-repulsive electromagnets with the same magnetic poles are respectively arranged at the top end surfaces of the suspended movable chuck 32 and the base 11, so that the movable chuck is supported by repulsive force.
Further, the outer parts of the fixed chuck 31 and the movable chuck 32 are respectively sleeved with a sterile plastic protective sleeve. The surface of the plastic bag is loosely sleeved with a sterile plastic protective sleeve, so that the plastic bag is waterproof and has a sterile effect. But also without affecting the closure of the fixed jaw 31 and the movable jaw 32.
Further, the strapping mechanism 2 is a glue strapping, and the strapping includes a first vertical strapping portion 21 integrally formed with the fixing clip 31, a second vertical strapping portion 22 detachably connected with the blocking bracket 1, and a horizontal strapping portion 23 disposed between the first vertical strapping portion 21 and the second vertical strapping portion 22. The transverse bundling part 23 penetrates through the movable chuck 32, and two ends of the transverse bundling part are respectively integrally formed with the first vertical bundling part 21 and the second vertical bundling part 22.
Here, the applicant wants to emphasize that: the length of the first and second vertical strapping portions 21, 22 will change with two different states of the movable clamp head 32.
