Background

The most common instruments in laparoscopic surgery are two pieces of operating instruments, namely an electrocoagulation hook and a suction apparatus, and bleeding is inevitably encountered during the operation. At the moment, the hematocele at the bleeding part is generally sucked clean by a suction apparatus, then the suction apparatus is pulled out immediately, an electrocoagulation hook is inserted, and the electrocoagulation hemostasis is carried out after accurate positioning. However, in case of bleeding, except for a few of oozing blood with a slow bleeding speed, the blood vessel is often broken under most conditions, at the moment, the bleeding is fast, particularly, the bleeding of an artery is large in bleeding amount and fast in speed, once the aspirator is moved away, the electrocoagulation hook is not inserted and positioned, the bleeding part is covered by accumulated blood instantly, the visual field is not clear, the bleeding point cannot be positioned accurately, and then the electrocoagulation hemostasis cannot be performed effectively, quickly and accurately. In this case, the suction apparatus can be used again to repeatedly suck blood, resulting in an increase in blood loss. Many physicians now blindly coagulate in the blood when the field of vision is obscured, causing damage to surrounding visceral tissues and even burning through surrounding large blood vessels causing catastrophic hemorrhage that endangers patient life and often requires a laparotomy to treat hemostasis.

In the existing products, a device combining an electrocoagulation hook and an aspirator is provided, but the largest problem of the related products is that the electrocoagulation hook at the head end cannot retract into the aspirator, so that the aspirator in the products can only play a role in sucking smoke but cannot play a very important and common operation manipulation of the traditional laparoscopic aspirator, such as scraping, sucking, jacking, and the like, thereby greatly reducing the practicability and operability of the related products.

In general, in laparoscopic surgery, it is often necessary to perform dissection operations in a very narrow space, and it is often only possible to accommodate 1-2 operating instruments, in addition to the necessary viewing lens. If bleeding occurs at the moment, the head end of the existing invention or apparatus is a round blunt end, and the existing invention or apparatus can only be used for rough operations such as massive excision and the like, can not be used for fine dissection operations, and can not meet clinical requirements.
