Disposable trocars Laparoscopic instruments for insertion through trocars. A trocar (or trochar) is a medical or veterinary device used in minimally invasive surgery.Trocars are typically made up of an awl (which may be metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal.
The practice of reusing medical devices labeled for only one use began in hospitals in the late 1970s. [8] After a thorough review by the U.S. FDA in 1999 and 2000, [8] the agency released a guidance document for reprocessed SUDs that began regulating the sale of these reprocessed devices on the market, [9] under the condition that third-party reprocessors would be treated as the manufacturer ...
In certain advanced laparoscopic procedures, where the specimen removed is too large to pull through a trocar site (as is done with gallbladders), an incision larger than 10 mm must be made. The most common of these procedures are removal of all or part of the colon ( colectomy ), or removal of the kidney ( nephrectomy ).
In 1904, King Gillette developed a double-edged safety razor blade with a disposable blade. [6] After 10 years, Morgan Parker, an engineer, developed and patented another type of disposable scalpel, consisting of an overlapping blade locked into a metal handle that allows for easily replacing dull and used blades with fresh sterile blades.

Laparoscopic stapling of sigmoid colon. Close-up demonstration of a surgical skin stapler. The first commercial staplers were made of stainless steel with titanium staples loaded into reloadable staple cartridges. Modern surgical staplers are either disposable and made of plastic, or reusable and made of stainless steel.
Once the trocar is placed, an optic scope is inserted. [25] Upon completion of the procedure, some patients may require sutures to stop any remaining bleeding. [ 25 ] This method tends to be better for classifying tubal disease as inspection of the inner structure allows for visualization of any lesions, adhesions, and endometriomas. [ 26 ]
During this period, a total of 1797 robotic surgeries were performed used 4 da Vinci surgical systems. There were 43 cases (2.4%) of mechanical failure, including 24 (1.3%) cases of mechanical failure or malfunction and 19 (1.1%) cases of instrument malfunction. Additionally, one open and two laparoscopic conversions (0.17%) were performed.
Single-port laparoscopy (SPL) is a recently developed technique in laparoscopic surgery. It is a minimally invasive surgical procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient's navel. Unlike a traditional multi-port laparoscopic approach, SPL leaves only a single small scar.
