Any laparoscopic surgery demands appropriate surgical instruments. Most surgeons nowadays have adapted to this different form of surgery and have particular preferences for certain types of graspers, dissectors and cutting instruments. The general component of laparoscopic instrument includes the hand grip, shaft, jaw and the tip.
The harmonic scalpel is a surgical instrument used to simultaneously cut and cauterize tissue. It is the latest device to have been introduced in last decade or so. Ultrasonic energy is famously used in Harmonic scalpel where ultrasonic energy is converted to mechanical energy at the active blade. The main mechanism is the active blade which delivers high-grade frictional force while the inactive upper arm holds tissue in apposition. Its main advantages include precise dissection, reliable hemostasis, less lateral thermal spread and charring mainly works by applying pressure and then sealing with a denatured protein coagulum while applying ultrasonic vibration to denature hydrogen bonds perform vessel coagulation.
Ultrasicon is the name given to the dissection method by harmonic. The transducer in the handpiece consisted of piezoelectric crystal sandwiched under pressure among metal cylinders. The ultrasonic generator converts ultrasonic energy into mechanical energy. The sealing of the vessels is achieved due to denatured protein coagulum which occurs due to tamponade and coaptation. It has three compatible probes that are the shear, blade and a hook. The shear can coagulate vessels up to 5 mm, whereas the hook and blade only 2 mm in diameter. It has the least thermal spread and smoke production of all the devices. Ethicon first introduced the world to HARMONIC ultrasonic technology and its precise dissection capability in 1998 with the release of the HARMONIC Scalpel Shears.
Manufactured and supplied by ETHICON, a part of Johnson and Johnson, it is a wonderful device available in various types. The latest one of the harmonic devices is HARMONIC ACE + 7 Shears with advanced hemostasis. It is one of the first devices with purely ultrasonic energy device with a 7-mm vessel sealing indication. It is known to have advanced adaptive tissue technology which delivers unmatched precision, multifunctionality, and now advanced hemostasis for stronger large vessel sealing. It ensures less tissue damage and it is claimed to be stronger, more reliable sealing device and is successful in being able to seal vessels with 7 mm diameter.
It has higher median burst pressure versus LigaSure 5-mm blunt tip, when sealing 5–7-mm vessels in the advanced hemostasis mode. Harmonic also has some credible reports, suggesting that it has better results in term of less postoperative pain complains by patient [3]. The development of ultrasonically activated coagulating shears in the early 1990s has provided an alternative to other methods of controlling blood vessels. The device divides tissue by using high-frequency (55,000 Hz) ultrasonic energy transmitted between the instrument blades. The active blade of the instrument vibrates longitudinally against an inactive blade over an excursion of 50–100 µm. Hence, this wonder device is still much in demand but cost can be a factor for every surgeon, otherwise a marvel of device.
In any case, things made by people don’t keep going long. A couple of things can last more than people, the sound concern is the drop in quality because of making and contracting with time. This is something that is continually unavoidable. Additionally, with mindful instruments, having their quality obliterated can’t be wagered since lives of the patients rely upon it. Hence, a need to positively outfit the instruments with the assistance and care they need is absolutely focal. This idea can take the state of basically an upkeep connection or a trickery fix or parts substitution. Regardless of the issue, it should all be done exactingly since the existences of patients rely upon it.
Since point topic specialists and specialists can’t present suggestion to their instruments on a level that is expected to keep up limit with respect to the instrument, an unapproachable should be guided concerning this. Somebody with a gigantic heap of obligation with fixing and changing careful instruments with high capacity and phenomenal client help. Enter Ophthalmon, a watchful contraption fix association that gives significant level relationship for any wary gadget that you may have. Despite the way that it fixes the Ethicon generation 3 ultracision harmonic scalpel, it fixes other Transducer Handpieces too. Ophthalmon is versatile and adaptable to the necessities of its customers. They give a free and certifiable evaluation for the client with the target that the client knows the condition and can appropriately take a choice. Ophthalmon is the best spot to go.
