Plasma Surgical

Last updated

Plasma Surgical is a privately held medical device company with headquarters in suburban Atlanta, Georgia, USA, with operations in the UK and France. The company was founded based on the work of plasma physics professor Nikolay Suslov, who developed a technology to apply plasma energy to surgically treat live tissue with minimal thermal damage.

Plasmas in surgery

Cold plasmas are extensively used in industry for critical surface cleaning and have been proposed for multiple applications in Plasma medicine, including sterilization or decontamination processes. Thermal plasmas are characterized as being macroscopically hot and have widespread industrial use in materials cutting, and more recently broad use in surgical procedures.

The origins of a thermal plasma with the ability to both cut and coagulate tissue lie in the early studies by the late John Glover and his colleagues at the Indiana University in the mid 1970s. Glover and his team described the first plasma scalpel [2] [3] and compared this to the use of the steel scalpel and electrosurgery. Although effective as a surgical tool, this relatively simple two electrode handpiece device involved a relatively high gas flow and in early pre-clinical and clinical use there was evidence of argon gas in the circulation with the concomitant risk of gas embolism. No subsequent development ensued and no commercially available system arose from this early work.

In the mid 1990s, Nikolay Suslov invented a multielectrode system that generated plasma with a higher power density using a very low level of current. [4] This design used a low level DC current to generate a spectrally pure plasma flow in a small electrode group that facilitated the design of small diameter handpieces capable of generating a high power density of plasma flow using a very low argon flow of typically 0.2 - 0.6 L/min. This approach was developed further in 1999–2008 to create the company's flagship product.

Products

The company's core product is the PlasmaJet system which utilizes an inert gas that is electrically excited to a plasma state, releasing three forms of energy: Light, Kinetic and Thermal. It is used for open and laparoscopic surgical procedures and the cutting, coagulation and removal of soft tissue by vaporization in gynecology, oncology, general surgery, and other areas. [5] and ovarian cysts, [6] and for tumor debulking. [7] The system was selected as the 2008 Innovation of the Year by the Society of Laparoendoscopic Surgeons. [8]

The PlasmaJet is currently cleared and available for use in the United States as a neutral plasma surgery system designed for cutting, coagulation and the removal of soft tissue by vaporization in open surgery and laparoscopic surgery. [9] The system also carries a CE mark and is approved and available for use in the European Union as a cutting and coagulation device in open and laparoscopic surgery.

History

In 1994, Professor Nikolay Suslov of Russia described a low voltage DC-excited multiple-electrode plasma surgery handpiece with low gas flow, signalling the possibility for effective clinical applications. Suslov's first US patent for plasma surgery device was published in 1998. [10] Following his findings and patent publication, Suslov and fellow professor Peter Gibson co-founded Plasma Surgical Limited in 2000. The company was headquartered in London, UK and had operations in Gothenburg, Sweden. The company introduced a prototype Neutral Plasma Coagulator at the American College of Surgeons Congress in 2002. [11]

In 2010 the company moved its headquarters from Europe to the US, establishing R&D, manufacturing and commercialization function in Roswell, Georgia, 20 miles north of Atlanta. [12]

In 2011, the company began broader commercialization efforts for the PlasmaJet in the US, Europe and Russia, with a total installed base of approximately 100 systems in hospitals and clinics. [13]

In 2012 the company received FDA clearance for an expanded indication for use, adding the removal of soft tissue by vaporization. [14]

He is a pioneer in the field of endoscopic surgery and has been the first to perform numerous innovative laparoscopic surgical procedures, never before accomplished (NYP). Fowler was also the first general surgeon to use the Harmonic Scalpel, a device that uses wave frequency to divide the tissue and vibration to coagulate blood vessels.

Gingivectomy is a dental procedure in which a dentist or oral surgeon cuts away part of the gums in the mouth.

A gum lift is a cosmetic dental procedure that raises and sculpts the gum line. This procedure involves reshaping the tissue and/or underlying bones to create the appearance of longer or symmetrical teeth, thereby making the smile more aesthetically pleasing. This procedure is typically done to reduce excessively gummy smiles or to balance out an asymmetrical gum line. The procedure, also known as crown-lengthening, has historically been used to treat gum disease. It is only within the past three to five years that dentists have commonly used this procedure for aesthetic purposes. The practice of cosmetic gum lifts was first developed in the late 1980s, but there were few oral surgeons and dental practitioners available to perform the procedures. Gum lifts can also include bone shaping to reduce the prominence of the upper jaw and even out the tooth and gum ratio. This method provides permanent results, while simple gum contouring may result in relapse or regrowth of the gingiva.

A microplasma is a plasma of small dimensions, ranging from tens to thousands of micrometers. Microplasmas can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.

Therapeutic endoscopy is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy, where the aim of the procedure is purely to visualize a part of the gastrointestinal, respiratory or urinary tract in order to aid diagnosis. In practice, a procedure which starts as a diagnostic endoscopy may become a therapeutic endoscopy depending on the findings, such as in cases of upper gastrointestinal bleeding, or the finding of polyps during colonoscopy.

<span class="mw-page-title-main">Endometrioma</span> Medical condition

Endometrioma is the presence of tissue similar to, but distinct from, the endometrium in and sometimes on the ovary. It is the most common form of endometriosis. Endometrioma is found in 17–44% patients with endometriosis.

Ovarian drilling, also known as multiperforation or laparoscopic ovarian diathermy, is a surgical technique of puncturing the membranes surrounding the ovary with a laser beam or a surgical needle using minimally invasive laparoscopic procedures. It differs from ovarian wedge resection, which involves the cutting of tissue. Minimally invasive ovarian drilling procedures have replaced wedge resections. Ovarian drilling is favored over wedge resection because cutting into the ovary might result in adhesions, potentially complicating postoperative outcomes. Ovarian drilling and ovarian wedge resection are treatment options to reduce the amount of androgen producing tissue in women with polycystic ovarian syndrome (PCOS). PCOS is the primary cause of anovulation, which results in female infertility. The induction of mono-ovulatory cycles can restore fertility.

Plasma medicine is an emerging field that combines plasma physics, life sciences and clinical medicine. It is being studied in disinfection, healing, cancer, and surgery. Most of the research is in vitro and in animal models.

A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is cut up in strips, or morcellated, into smaller pieces inside the patient's abdominal cavity in order to extract from the abdomen. It can consist of a hollow cylinder that penetrates the abdominal wall, ending with sharp edges or cutting jaws, through which a grasper can be inserted to pull the mass into the cylinder to cut out an extractable piece.
