Medical surface adhesives are utilized in surgical procedures across approximately 20 medical specialties-including general surgery, laparoscopy, neurosurgery, cardiothoracic surgery, obstetrics and gynecology, urology, orthopedics, dentistry, otolaryngology, and burn and plastic surgery-serving functions such as hemostasis, sealing, bonding, leak plugging, embolization, adhesion prevention, and the fixation of comminuted fractures.
The clinical scope of medical surface adhesives continues to expand, finding application in minimally invasive surgeries within fields such as thoracic surgery and vascular surgery.
For instance, in vascular surgery, medical adhesive closure techniques are employed in the minimally invasive treatment of lower extremity varicose veins. This technique is characterized by the absence of thermal injury and a low recurrence rate; it requires neither open incision nor spinal anesthesia, relying instead solely on local anesthesia and micro-needle puncture to effectively treat the affected veins. Domestically produced venous adhesive closure products have now received regulatory approval and have been successfully integrated into standardized clinical practice.
Endoscopic Adhesive Spraying Device
The adhesive spraying device consists of an adhesive reservoir bottle and a specialized spray nozzle designed for use in conjunction with endoscopes; notably, it does not utilize Freon as a propellant. Constructed from medical-grade polyethylene, the device is hermetically sealed via thermal compression and subsequently packaged following sterilization using ethylene oxide.
