Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 1\) 18 years old ≤ age ≤ 75 years old, regardless of gender;

2\) Based on the preoperative CT examination results, it is determined that the patient has at least one blood vessel that needs to be coagulated during the surgery, with a diameter greater than 5mm but less than or equal to 7mm;

3\) Before the start of the study, the patient is willing and able to sign an informed consent form approved by the ethics committee;

4\) The patient understands the clinical study, cooperates with the research procedure, and is willing to conduct postoperative follow-up according to the protocol.

Exclusion Criteria

* 1\) Patient body mass index (BMI) ≥ 35.0 kg/m2;

2\) Prothrombin time greater than 5 seconds;

3\) Researchers have determined that the tumor may invade the target blood vessel, which may affect the operation or effectiveness of vascular occlusion and disconnection;

4\) Researchers have determined that there may be variations, deformities, or calcifications in the target vessel that may affect the evaluation of the primary endpoint, which may affect the operation or effectiveness of vascular occlusion and disconnection;

5\) Patients receive preoperative chemotherapy and radiation therapy;

6\) Patient's fasting blood glucose ≥ 11.1mmol/l;

7\) Hypertensive patients' blood pressure has not been effectively controlled, and their blood pressure is ≥ 140/90 millimeter of mercury （mmHg） in a stable state after medication;

8\) Pregnant or lactating women, or women with pregnancy plans during the trial period;

9\) Participated in other clinical studies within 3 months;

10\) Individuals with mental disorders and lack of autonomous behavioral ability;

11\) Other researchers believe that it is not suitable to participate in the experiment.
