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.
In a large survey of 155,987 gynecologic procedures and 17,216 general surgery procedures, the Veress needle technique was used in 78% of them. Gynecologists (81%) used the tool more often than general surgeons (48%) who are far more likely to use the open access technique.
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.
More recently, studies by Ates et al. and Roberts et al. have described variants of an intracorporeal sling-based single-port laparoscopic appendectomy with good clinical results. [11] Also, a trend is increasing towards single-incision laparoscopic surgery (SILS), using a special multiport umbilical trocar. [12]
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 ]
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 ...
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 ...
A laparoscopic hernia repair is when the hiatal hernia is corrected using a covering for the mesh that is used to repair the weakened area. The defect is then measured and the mesh is stapled into place. [6] A benefit of performing Laparoscopic hernia repair is shorter recovery times compared to other methods.
