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.
Several studies have pointed out that for various laparoscopic surgical applications (such as cholecystectomy, groin hernia repairs and appendectomies), creating pneumoperitoneum by using a Veress needle is not always as safe and effective as other techniques (e.g. direct trocar insertion (DTI)).
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.
The instruments may be used in either open or laparoscopic surgery, different instruments are used for each application. Laparoscopic staplers are longer, thinner, and may be articulated to allow for access from a restricted number of trocar ports. Some staplers incorporate a knife, to complete excision and anastomosis in a single operation ...
General surgery is a specialty focused on the abdomen; the thyroid gland; diseases involving skin, breasts, and various soft tissues; trauma; peripheral vascular disease; hernias; and endoscopic procedures. Instruments can be classified in many ways, but, broadly speaking, there are five kinds of instruments. Cutting and dissecting instruments
The straight blades are used for cutting tissue near wounds, and curves are used for cutting thick tissue. [5] Metzenbaum scissors were invented by Myron Metzenbaum (1876–1944). [5] This tool was widely used for tonsillectomy (the surgical removal of the tonsils). [5] The lighter and longer handle allows it to be used in tighter operating ...
With SILS, a more conventional view of the field of surgery is seen compared to NOTES. The equipment used for SILS is familiar to surgeons already doing laparoscopic surgery. Most importantly, it is easy to convert SILS to conventional laparoscopy by adding a few trocars; this conversion to conventional laparoscopy is called 'port rescue'.
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 ...
