Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a ring-shaped ultrasonic cutting device under endoscopic monitoring. Background Art

[0002] Ultrasonic scalpel is a surgical cutting device that is used for soft tissue cutting and hemostasis, especially for large blood vessels. It is significantly better than electric scalpel in hemostasis. It can effectively seal arteries and veins less than 3MM. At present, ultrasonic scalpels only have linear blades, which are not suitable for some special application scenarios. This design is a circular ultrasonic cutting system designed for specific scenarios. Scenarios that require circular cutting include but are not limited to hemorrhoid cutting, circumcision, and polyp cutting.

[0003] Currently, hemorrhoid surgeries include traditional ligation, band ligation, and stapler circular resection. However, both ligation and stapler resection have the risk of postoperative bleeding, and band ligation is not suitable for large hemorrhoids. Ultrasonic circular cutting can not only complete the resection of the mucosa on the entire circumference of hemorrhoids, but also can remove a single hemorrhoid. It has a good hemostatic effect and reduces the risk of postoperative bleeding. No suturing is required during the operation, there are no staples, and there is no long-term foreign body reaction. The ultrasonic circular cutting system integrates an endoscope system and can be operated under video monitoring, taking into account the scope of application of several existing surgical methods and avoiding the risks of existing surgeries.

[0004] Circumcision surgery can be divided into traditional surgical methods and stapler cutting methods. There is a risk of postoperative bleeding, and the stitches or staples need to be removed after the operation. Traditional surgery is to remove the excess foreskin and then suture it, which takes a long time and causes a lot of bleeding during the operation. The stitches need to be removed after the operation. The stapler cutting method takes a short time and there is no bleeding during the operation. The staples need to be removed after the operation, which is easy to cause infection and the recovery after the operation is slow. Summary of the invention
