Evaluation of the Efficacy and Safety of the Thoracoabdominal Endoscopic Surgery System Produced by Shenzhen Cornerstone Robotics Technology Co., Ltd. in Remote Laparoscopic Surgeries for Urology, General Surgery, Gynecology and Thoracic Surgery
Age ≥ 18 and ≤ 80 years;
Patients confirmed by investigators eligible for surgeries in urology (e.g., partial nephrectomy (transperitoneal/retroperitoneal), radical prostatectomy, pyeloplasty, etc.), general surgery (e.g., distal/radical total gastrectomy for gastric cancer, radical resection for colorectal cancer, hepatectomy/splenectomy, etc.), gynecology (e.g., radical hysterectomy plus pelvic lymphadenectomy, etc.) and thoracic surgery (e.g., segmental/lobectomy, radical esophagectomy, etc.).
Subjects voluntarily participate in the clinical trial, and subjects or their guardians give informed consent and sign the informed consent form.
Willing to cooperate with and complete trial follow-ups and relevant examinations.
Need for emergency surgery (e.g. gastric cancer, colorectal cancer combined with perforation, bleeding, obstruction, etc.);
With other malignancies or a previous history of other malignancies.
Preoperative imaging suggests that the tumour has distant metastases.
The patient has a history of relevant surgery or previous history of other malignancy and is judged by the investigator to be unsuitable for enrolment.
Patients confirmed by investigators eligible for surgeries in urology (e.g., partial nephrectomy (transperitoneal/retroperitoneal), radical prostatectomy, pyeloplasty, etc.), general surgery (e.g., distal/radical total gastrectomy for gastric cancer, radical resection for colorectal cancer, hepatectomy/splenectomy, etc.), gynecology (e.g., radical hysterectomy plus pelvic lymphadenectomy, etc.) and thoracic surgery (e.g., segmental/lobectomy, radical esophagectomy, etc.).
