Description

A kind of endoscopic blood vessel damage repair device

Technical field

The invention relates to the technical field of medical devices, and in particular to an endoscopic blood vessel damage repair device.

Background technique

During thoracic surgery, most blood vessels are freed. During the freeing process, the blood vessel wall is easily damaged, causing massive bleeding and endangering the patient's life. For the treatment of blood vessel injuries, it is often necessary to use needles and threads to suture. Before suturing, use a suction device to absorb the blood that overflows from the blood vessel break and expose the field of vision. However, the main operating hole of current thoracoscopic surgeries is often small, and it is impossible to access multiple instruments at the same time to expose the field of view and adjust the angle, resulting in some angles that cannot be sutured. In addition, during the process of removing blood vessels, there is almost no damage to the back of the blood vessels. Opportunity to sew. It will lead to failure of suture hemostasis, increase the chance of thoracotomy and even death.

Liquid; the driving member provides water pressure through the liquid, causing the rubber column 330 to slide out from the arc hole 110 and compress the titanium clamp 200. After clamping to stop bleeding, the rubber column 330 is separated from the titanium clip 200, and the titanium clip 200 remains in a clamping and hemostatic state to the bleeding port.

The driving component includes an external tube 340 and a syringe 350. A mounting hole is provided on the side wall of the end of the vascular damage repair device body 100 away from the titanium clip 200. The outer wall of the external tube 340 is sealed and fixedly connected to the mounting hole. One end of the external tube 340 extends into the body 100 of the damaged blood vessel repair device and is connected to the connecting tube 310 , and the other end is connected to the outlet of the syringe 350 .

The invention provides an endoscopic blood vessel damage repair device. During thoracic surgery, when blood vessel damage is discovered, the blood vessel damage repair device tube body 100 is inserted into the patient's body for negative pressure suction, and the blood vessel damage repair device tube body is adjusted. 100 to the appropriate position, and suck away the bleeding. When there is no blood leaking out from the periphery of the damaged blood vessel repair device body 100 and all the bleeding is sucked out by the damaged blood vessel repair device body 100, it can be judged that the damaged blood vessel repair device body 100 fully covers the bleeding. point, inject liquid into the connecting tube 310 through the syringe 350, and apply pressure to the rubber column 330 in the branch pipe 320 through hydraulic pressure, so that the rubber column 330 slides outward, and during the sliding process, it abuts against the abutting portion 240 of the titanium clip 200. Tightly, the titanium clip 200 clamps the damaged opening of the blood vessel to achieve the purpose of stopping bleeding. This method combines the vascular damage repair device body 100 and the titanium clip 200, so that the structure can not only perform negative pressure suction for bleeding, but also assist in finding bleeding points. At the same time, it can clamp and stop bleeding, and reduce the number of instruments entering the patient's body. It is convenient to operate on positions with awkward angles or that cannot be directly exposed, which improves the convenience of surgery and at the same time reduces the learning curve for surgeons to learn to stop bleeding.
