Problems solved by technology

[0004] The mesh wrapping method achieves the effect of compression and hemostasis by fixing the mesh in multiple places, but there are the following problems: (1) The mesh wrapping method requires a group of medical personnel to stop the bleeding after the laparotomy, and another group of medical personnel according to the injury. Cutting the mesh at the site will increase the operation time and waste intraoperative resources; (2) During the operation, the liver needs to be fully dissociated and sutured in multiple places to fix the mesh, which reduces the operation efficiency and increases the intraoperative risk; (3) " "Medium cutting" and suturing operations are relatively random, which may objectively cause package "mismatch" and uneven pressure. Whether the cutting is appropriate and whether the fixation is really limited by the experience of the surgeon, the operation is relatively complicated and easily affected by human factors The effect of compression on hemostasis

Embodiment 1

[0053] Such as Figure 1~3 As shown, a pressurized hemostatic right side sleeve for hepatic trauma has a sleeve body 1 as a whole, and the sleeve body is composed of a curved diaphragm surface layer 11 and a flat visceral surface layer 12. The edges are sutured to form the edge 3 of the sleeve body. The edge 3 is an incomplete ellipse, and the unsewn side is the sleeve opening 2. The cross section of the sleeve body 1 is arched, which is roughly the same shape as the liver. The sleeve body can cover the right liver and the liver. The inner lobe of the left liver has a V-shaped notch 6 on the visceral surface of the sleeve body. When the right side sleeve covers the right liver, the hilar blood vessels and biliary tract can pass through the sleeve body 1 through the V-shaped notch 6 . The positions of the absorbing pressurized dry trauma hemostasis sleeve on the right side are defined according to the position of the liver. The sleeve diaphragm surface layer 11 corresponds to t...

Embodiment 2

[0056] As shown in the figure, there is a pressurized hemostatic right side sleeve for hepatic trauma, and the rest is the same as in Embodiment 1. There are three positioning lines 4 and three fastening straps 5 on the right sleeve, wherein the second fastening strap 52 and The third fastening belt 53 is distributed on the peripheral surface of the sleeve body 1 on both sides of the first fastening belt 51 . Three positioning lines 4 and three fastening straps 5 can achieve the best hemostatic fixation effect. The drawing section of the second positioning line 42 is fixed obliquely to the outside along the tangent line of the dirty surface at 8°, and the drawing section of the third positioning line 43 is fixed obliquely to the outside along the tangent line of the dirty surface at 8°.

Embodiment 3

[0058] As shown in the figure, a pressurized hemostatic left sleeve for hepatic trauma has a sleeve body 1 as a whole, and the sleeve body is composed of a curved diaphragm surface layer 11 and a flat visceral surface layer 12, and the visceral surface layer 12 is an incomplete ellipse The diaphragm surface layer 11 is sutured along the curved edge of the visceral surface layer 12 to form the edge 3 of the sleeve body 1. The opening is the sleeve mouth 2. The cross section of the sleeve body 1 is slightly arched, which is roughly the same shape as the liver. The sleeve body 1 May cover the lateral lobe of the left liver. The positions of the absorbing pressurized dry trauma hemostasis sleeve on the left side are defined according to the position of the liver. The diaphragm surface layer 11 of the sleeve body corresponds to the diaphragmatic surface of the liver, and the visceral surface layer 12 of the sleeve body corresponds to the visceral surface of the liver. The orientati...

Abstract

The invention belongs to the field of medical apparatus and discloses a pressurizing blood-stopping device for liver trauma. The main body is a sleeve body; the sleeve body is formed by a diaphragm surface and a hepatic surface; a connection part between the two is a sleeve body edge; at least three positioning lines and at least one fastening belt are fixed on the sleeve body; each positioning line is formed by a free section and a drawing section; one end point of the first positioning line is fixed outside the edge; drawing section end points of the second positioning line and the third positioning line are all distributed on the inner side of the sleeve body edge; the drawing section of the second positioning line outwardly inclines 5 to 15 degrees along a direction of the tangent line of the diaphragm surface and then is fixed; the drawing section of the third positioning line; outwardly inclines 5 to 15 degrees along a direction of the tangent line of the diaphragm and then is fixed; the fastening belt is circumferentially fixed along the sleeve body; and the first fastening belt is fixed in the middle part of the sleeve body. The beneficial effects of the pressurizing blood-stopping device for liver trauma are that excessive ionization of the liver can be avoided and operation trauma can be reduced; and continuous even pressurizing blood stopping effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a pressurized hemostatic device for liver trauma. Background technique [0002] The liver is the largest solid organ in the human body. Liver trauma accounts for about 20% of abdominal trauma. It is a relatively common abdominal injury. According to the 6-level grading method for liver injury by the American Academy of Trauma Surgery (AAST), injuries above grade III That is severe liver trauma, the mortality rate is over 50%, and the mortality rate is as high as 80%-90% when combined with hepatic vein or retrohepatic inferior vena cava injury. The most thorough treatment for liver trauma is to resect the damaged liver segment or lobe, which can effectively stop the bleeding and avoid complications such as infection and bile leakage that may occur later. However, severe liver trauma is often combined with other organ injuries, and even pathophysiological chang...
