Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical devices, in particular to a blood vessel closure surgical device with intelligent temperature control function. BACKGROUND

[0002] The blood vessel closure system realizes hemostasis effect through computer feedback control bipolar electrocoagulation technology. The system can safely close blood vessels with a diameter of less than 7 mm by deforming and fusing collagen and elastin in the blood vessel wall, thereby significantly improving surgical efficiency. Compared with traditional hemostasis methods, the blood vessel closure system can greatly reduce the operation time and reduce the amount of postoperative analgesic drugs used by surgical personnel. In recent years, the breakthrough of the blood vessel closure system technology focuses on the refinement of operation and the improvement of tissue adaptability. In the field of laparoscopic liver resection, the problem of mechanical rupture of microvessels and bile ducts caused by traditional equipment during tissue compression is solved. The operator can electrocoagulate in batches according to the thickness of the tissue, thereby significantly reducing the incidence of bile leakage in liver surgery. The blood vessel closure system has been expanded from general surgery to multiple specialty applications, showing wide adaptability and providing technical support for the operation process.

[0003] The existing traditional blood vessel closure system has a high failure rate in the treatment of calcified blood vessels during the current use process. The impedance characteristics of calcified tissue change, resulting in uneven energy transmission. At the same time, it is difficult to identify in microstructure surgeries such as thyroid surgery and nerve and blood vessel dense area surgery. It is difficult to identify small diameter blood vessels and lymphatic vessels with the naked eye, which can easily cause accidental injury or postoperative risk. Moreover, the existing system has limited adaptability to changes in tissue thickness, and the system closure thickness control is insufficient. When the tissue is too thick, the closure layer may not reach a sufficient depth, increasing the risk of postoperative rebleeding. Therefore, a blood vessel closure surgical device with intelligent temperature control function is needed to solve these problems. SUMMARY
