Description

Technical Field

[0001] The utility model relates to the technical field of medical waste gas collection devices, in particular to a waste gas collection device for laparoscopic surgery. Background Art

[0002] As we all know, urology specializes in kidney transplantation, laparoscopic surgery, adrenal surgery for adrenal adenomas, pheochromocytomas, primary aldosteronism, and other adrenal gland tumors, surgery for kidney, bladder, and prostate tumors, prostate cancer surgery, ureteropelvic junction stenosis surgery, surgical treatment of kidney, ureteral, and bladder stones, transvesical and retropubic prostatectomy, transurethral resection of bladder tumors, cystoscopic holmium laser bladder tumor resection, hypospadias and penile flexion surgery, and extracorporeal lithotripsy for kidney, ureteral, and bladder stones. In recent years, the department has expanded its expertise in the diagnosis and treatment of chronic prostatitis, as well as the diagnosis and treatment of male sexual dysfunction and infertility.

[0003] A clear surgical field of view is key to ensuring the safety of laparoscopic surgery. The widespread use of a large number of electrosurgical devices in laparoscopic surgery can cause smoke to fog up when cutting tissue and electrocoagulating bleeding tissue, interfering with the clarity of the surgical field of view, thereby affecting the safety and speed of the operation. Timely removal of smoke from the abdominal cavity and restoration of vision are key to continuing the operation. Traditional smoke evacuation methods involve exhausting smoke through the side holes of the operating sheath. The smoke contains carbonized tissue, blood components, and toxic and harmful substances. In addition, the CO2 used to establish pneumoperitoneum is also exhausted, causing symptoms such as hypoxia, dizziness, nausea, and a pungent smell. This pollutes the operating room air and harms the health of medical staff and patients. Utility Model Content
