• Electrosurgical Vessel Sealer Devices for Hemorrhoidectomy: Less Bleeding, Less Pain, Faster Recovery

  Aug 01, 2025

  Hemorrhoids are a common anal disease, with 10% to 20% of patients requiring surgical treatment [1]. Common issues with traditional hemorrhoidectomy are postoperative bleeding and pain. The Agiseal electrosurgical vessel sealer divider, a novel tissue-cutting and coagulating device, brings significant improvements to hemorrhoid surgery.   Agiseal,independently developed by ShouLiang-med, uses advanced real-time feedback and intelligent generator technology. By delivering high-frequency electrical energy combined with constant pressure between the jaws, it causes denaturation of collagen and fibrin within the target vessels. It fuses the vessel walls, forming a transparent band that achieves permanent lumen closure. Its advantages include: no need for excessive separation during closure, and faster closure speed; no smoke, maintaining a clear surgical field; and low local temperatures, minimizing damage to surrounding tissues. According to reports [2], the United Kingdom has successfully applied electrosurgical vessel sealer divider in haemorrhoidectomy procedures, achieving excellent haemostasis outcomes and significantly reducing postoperative pain in patients.    Traditional mixed hemorrhoidectomy is often associated with significant bleeding, which not only prolongs surgery time but also obscures the surgical field and reduces procedural accuracy. Conventional haemostasis methodssuch as ligation or electrocoagulation are also prone to causing collateral damage to surrounding tissues, thereby delaying wound healing. The application of the electrosurgical vessel sealer divider allows for pre-closure of haemorrhoidal tissue vessels prior to excision., resulting in minimal bleeding during excision along the closure zone. Furthermore, this technique eliminates the need for conventional suture ligation of the stump, simplifying the procedure and shortening operative time. Its core principle (inducing fibrin deformation and coagulation) also ensures safe and reliable hemostasis [3].   In traditional surgery, suture ligation of the hemorrhoidal pedicle tissue easily triggers sphincter spasm, leading to severe postoperative pain.  The Agiseal hemorrhoidectomy does not require ligation of the haemorrhoidal tissue, thereby reducing the incidence and intensity of postoperative pain from the source. Additionally, the sealing process causes minimal thermal damage to surrounding tissues, effectively avoiding burns and tissue edema caused by the thermal effects of electrocautery. Postoperative pain is typically controlled with oral medications alone, significantly reducing discomfort and minimizing the risk of drug side effects [4].   Benefiting from advantages such as minimal intraoperative bleeding, minimal tissue damage, and milder postoperative pain, patient recovery is accelerated, and hospital stays are significantly shortened. Although the single-use cost of the electrosurgical vessel sealer divider may be higher than traditional instruments, preliminary statistics show that the overall hospitalization costs for patients do not increase significantly,which may be mainly attributed to the effective reduction in the number of hospital days [3].   In summary, for patients with grade III to IV mixed hemorrhoids, the use of electrosurgical vessel sealer divider for hemorrhoidectomy is more advantageous than traditional hemorrhoid surgery in terms of reducing intraoperative blood loss and shortening hospital stay [3]. Its precise, efficient, and minimally invasive characteristics provide patients with a more comfortable and faster recovery experience.     Reference: [1] BLEDAY R，PENA JP，ROTHENBERGER DA，et al.Symptomatic hemorrhoids: current incidence and compli -cations of operative surgery［J］.Dis Colon Rectum，1992，35（5）:471-481.

• Agiseal Empowers Minimal Invasive Surgery: Tackling the Challenges of Radial Cystectomy for Bladder Cancer

  Jul 17, 2025

  Bladder cancer is one of the most common malignancies of the urinary system. Radical cystectomy remains the golden standard for treating muscle-invasive bladder cancer, yet it is considered one of the most complex and demanding procedures in urologic surgery. The main challenges include intricate pelvic anatomy, dense distribution of vital vessels and nerves, high risk of bleeding or rectal injury, extensive surgical scope requiring en bloc removal of the bladder and prostate, iliac lymphadenectomy, and complex urinary diversion with significant postoperative complications--all of which severely impact surgical outcomes and patient recovery.     With the advancement of minimally invasive techniques such as laparoscopy and cystoscopy, these challenges are gradually being overcome. Leading experts like Professor Zhang Zheng’s team at Peking University First Hospital have demonstrated mature surgical capabilities. During radical cystectomy, Prof. Zhang frequency employs the AGISEAL SL0844 instrument to efficiency and safely manage lateral bladder pedicles and pelvic lymph mode dissection. AGISEAL enables direct coagulation of deep vascular networks--including the dorsal vein complex--avoiding the limited visibility and complexity associated with traditional suturing. This reduces the need for perioperative transfusions and minimizes secondary pelvic bleeding. Additionally, AGISEAL enables rapid and effective handling of obturator vessels, significantly improving surgical efficiency and reducing operative time. With no foreign material left behind, it supports better postoperative recovery and demonstrates strong clinical performance. As a result, AGISEAL has become a preferred energy device in complex urologic procedures.    Proven across multiple cases, AGISEAL is well-suited for the demands of urologic surgery and serves as a reliable tool in high-difficulty radical cystectomy for bladder cancer.
