The clinical value of laparoscopic negative pressure irrigation catheters is fully demonstrated in various surgical procedures. It not only serves as a tool for maintaining a clear field of vision, but also plays a crucial role in infection control, oncology principles, and postoperative recovery. The depth of its application reflects the philosophy of minimally invasive surgery - "small incision, big impact".

General Surgery and Hepatobiliary Surgery: Treating Acute Bleeding and Infection

During laparoscopic cholecystectomy, when dissection of the gallbladder bed is performed, there may be bleeding or leakage of bile from the accessory bile duct. The negative pressure irrigation catheter can quickly remove accumulated blood and bile, precisely locate the bleeding point or leakage site, and at the same time clean the local area with the irrigation fluid, creating ideal conditions for subsequent electrocoagulation or clamping. In infectious surgeries such as appendicitis and digestive tract perforation, its value is even more prominent. It can efficiently remove pus and abdominal pus, and perform a large amount of normal saline irrigation, directly reducing the bacterial load in the abdominal cavity, which is a core step in reducing postoperative abdominal infection and adhesions.

Gynecological Surgery: Protecting the Pelvic Environment and Precise Operations

In gynecological surgeries such as uterine fibroid removal, ovarian cystectomy, ectopic pregnancy surgery, and excision of endometriosis lesions, if the accumulated blood and endometrial fragments in the pelvic cavity are not thoroughly cleaned, it can be a significant cause of postoperative pain, adhesions, and infertility. Negative pressure irrigation catheters can gently and thoroughly clean the pelvic cavity, especially in concealed areas such as the uterine rectal recess. In gynecological tumor surgeries, adhering to the "tumor-free principle" is of utmost importance. The irrigation catheter can be used for the final irrigation of the surgical field and collect the irrigation fluid for testing to assess whether there are any cancer cell detentions.

Urology and Gastrointestinal Oncology Surgery: Safeguarding in Complex Anatomy

In laparoscopic surgeries such as radical prostatectomy and partial nephrectomy, the surgical field is deep and the anatomy is complex, with extremely high requirements for bleeding control. Negative pressure irrigation catheters can maintain the clarity of the prostate fossa or renal fossa. In laparoscopic radical resection of colorectal cancer, before intestinal incision and anastomosis, a catheter is needed to rinse the distal intestinal cavity to reduce the risk of tumor cell implantation and anastomotic infection. After lymph node dissection, rinsing in the area also helps to remove detached adipose and lymphatic tissues.

In summary, from simple hernia repair to complex tumor radical resection, the application of negative pressure irrigation catheters has been integrated throughout the entire process of minimally invasive surgeries. By achieving "real-time purification" of the surgical field, it directly contributes to the precision, safety, and thoroughness of the surgery, ultimately translating into "less postoperative pain, faster recovery speed, and lower complication rates" for patients, perfectly demonstrating the advantages of minimally invasive surgeries.
