Background
In the surgical operation, when tissue and organs with rich blood flow are treated, in order to avoid excessive bleeding during operation, a method of controlling the blood flow of main blood vessels is often used to reduce blood supply to the tissue, thereby reducing the risk of excessive bleeding during treatment of target tissue and organs. As in liver resection, the bleeding risk of the liver resection procedure is often reduced by blocking portal blood flow. The current common practice in clinic is to wrap an elastic wire around a target blood vessel after exposing the blood vessel to be controlled through surgical dissection, and to press the target blood vessel by tightening the wire so as to control the blood flow of the blood vessel; another method is to control blood flow by clamping the target vessel with a hemostat.
The current operation of vascular flow control suffers from the following disadvantages: 1. whether wires or jaws are used, the operation process under the endoscope becomes more difficult due to the limitation of an operation path, and the operation which can cause massive hemorrhage is limited to be successfully and safely finished under the endoscope; 2. the operation of the jaws to control blood flow may cause damage to the blood vessel and may not achieve the goal of effectively controlling blood flow; 3. the clamp head part has insufficient curvature, so that the clamp cannot clamp a specific target blood vessel, and the curvature is too large to pass through the endoscope operation hole, so that the application of the clamp head part under an endoscope is limited. 4. In order to achieve the purpose of winding a target blood vessel by a wire under the endoscope, multi-step operation is required, the operation difficulty and risk are increased, and the application range of the operation under the endoscope is limited.
Aiming at the existing operation technology for controlling the blood flow of the target blood vessel, a device capable of encircling the target blood vessel and pressurizing the blood vessel is needed, in particular to an operation auxiliary device which meets the restriction of the operation condition of a endoscope. The blood vessel blood flow control device capable of controlling the curvature of the device, controlling the blood flow around a target blood vessel, adjusting the air sac to tighten the blood vessel, locking the needle body and the elastic strip after being matched with bending, and having simple structure, convenient use and small damage is needed in the operation process.
