Fort Worth surgical instruments

Proper care and maintenance is a must for surgical tools like safety scalpels in Fort Worth. They need to be sterilized and disinfected before and after use. When it comes to instruments like scalpel, forceps, retractors etc. it is understandable that they will be used on vital body organs so you must ensure that they are completely germ free and disinfected before you end up using them. If the surgical instruments are cleaned and disinfected properly there is little to no chance of infections.

Proper maintenance of these instruments are required in Fort Worth, and it also increases the life span of the instruments. This results in reducing extra costs like repairs and replacements. Also you need to make sure that the instruments which are disposable are being disposed in a proper way as per the health regulations of Fort Worth. You do not want them to get used by someone else. So ensure that all needles and other disposable surgical instruments are gathered and properly disposed off, since failure to do so will allow microorganisms to spread to and cause further diseases. These are some of the factors which everyone who uses operating room instruments must keep in mind; they will help in ensuring the safety of the patient as well as the other people in the Fort Worth area. Hospitals have proper procedures for disposing off such medical devices as well.

History and Use of Scalpels in Surgery

Hospitals can be scary sometimes but we can’t deny the fact that millions of lives are saved in these institutions every day. Being a doctor is definitely not an easy affair. Not only do these professionals have to become masters in understanding human biology but they also have to perfect their skills and capabilities of using various medical instruments. Can you think of a painter without the required paint brushes? Or a carpenter without his tools? Similarly, a doctor without his medical devices would be just like an audience on a show where, ideally, he should be performing on stage. No operation or diagnosis or procedure or even test can be carried out without necessary tools and equipment. It is important to know what these tools are and what their utilities are.

So if you are interested in medical tools and procedures and would like to understand how these are carried out, here is a list of the most basic medical instruments that you can find on an operating room. Hope this article helps you in your search for information.

# Scissors

The use of scissors as operating room instruments need not be highlighted or stated. No operation can be done without scissors. Scissors used in surgery come in two main types: Metzenbaum and Mayo scissors. Metzenbaum scissors are used in case of cutting or dissecting soft delicate tissues. Mayo scissors are preferred for cutting hard tissues such as joints. These scissors are used to cut thick tissues located in the breast and the muscles. Made up of stainless steel, these scissors are usually manufactured in variable lengths.

# Scalpel

Whether it is a major or a minor operation, a scalpel plays a very vital role in all of them. It is a knife that comes with stainless steel blades. Each and every surgery has its different needs but during every surgery, a correct incision is a must which cannot be carried out without a scalpel.

# Forceps

Forceps look like kitchen tongs. It allows the surgeon to hold and grasp the skin tissues firmly. Whether it is clamping the arteries or holding a part of intestine while operating, forceps can be relied upon. Also, this surgical instrument comes in a range of sizes so that the surgeon can choose one depending upon the need of the situation. The large ones are designed to hold a baby’s head and their main purpose is to safely get the baby out from the birth canal during a cesarean.

Of course there are other tools as well which will vary from surgery to surgery. They are manufactured with a wide variety of materials like platinum, stainless steel, tungsten carbide, chromium and other non-reactive and high strength metals. Designs and applications of medical devices have also evolved much over time. The more we advance into health care and medical science, the more new tools and equipment we will create for aiding surgeons in performing life saving procedures.

Most Common Operating Room Instruments

Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds, connect or remove parts of the bowels or lungs. A more recent development, from the 1990s, uses clips instead of staples for some applications; this does not require the staple to penetrate.

Stapling is much faster than suturing by hand, and also more accurate and consistent. Staples are primarily used in bowel and lung surgery, because staple lines are more consistent and therefore less likely to leak blood, air or bowel contents. Still, several randomized controlled trials have shown no significant difference in bowel leakage after anastomoses performed either manually with suture by experienced surgeons, or after mechanical anastomoses with staples. In skin closure, dermal adhesives (skin glues) are also an increasingly common alternative.

Staplers were originally developed to address the perceived problem of patency (security against stenosis or occlusion of the lumen) and tightness (security against leaks of blood or bowel contents) as well as easiness and quickness in performing the anastomosis. Leaks from poor suturing of bowel anastomoses was at that time a significant cause of post-surgical mortality. More recent studies have shown that with current suturing techniques there is no significant difference in outcome between hand sutured and mechanical anastomoses, but mechanical anastomoses are significantly quicker to perform.

The technique was pioneered by a Hungarian surgeon, Humor Hultl, known as the "father of surgical stapling". Hultl's prototype stapler of 1908 weighed eight pounds (3.6 kg), and required two hours to assemble and load. Many hours were spent trying to achieve a consistent staple line and reliably patent anastomoses.

The early instruments, by developers including Hultl, von Petz, Friedrich and Nakayama, were complex and cumbersome to use. The technology was refined in the 1950s in the Soviet Union, allowing for the first commercially produced re-usable stapling devices for creation of bowel and vascular anastomoses. Mark M. Ravitch, brought a sample of stapling device after attending a surgical conference in USSR, and introduced it to entrepreneur Leon C. Hirsch, who founded the United States Surgical Corporation in 1964 to manufacture surgical staplers under its Auto Suture brand. Until the late 1970s USSC had the market essentially to itself, but in 1977 Johnson & Johnson's Ethicon brand entered the market and today both are widely used, along with competitors from the Far East. USSC was bought by Tyco Healthcare in 1998, which became Covidien on June 29, 2007.

Safety and patency of mechanical (stapled) bowel anastomoses has been widely studied. It is generally the case in such studies that sutured anastomoses are either comparable or less prone to leakage. It is possible that this is the result of recent advances in suture technology, along with increasingly risk-conscious surgical practice. Certainly modern synthetic sutures are more predictable and less prone to infection than catgut, silk and linen, which were the main suture materials used up to the 1990s.

One key feature of intestinal staplers is that the edges of the stapler act as a haemostat, compressing the edges of the wound and closing blood vessels during the stapling process.

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. Both types are generally loaded using disposable cartridges.

The staple line may be straight, curved or circular. Circular staplers are used for end-to-end anastomosis after bowel resection or, somewhat more controversially, in esophagogastric surgery. 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. Staplers are used to close both internal and skin wounds. Skin staples are usually applied using a disposable stapler, and removed with a specialized staple remover. Staplers are also used in vertical banded gastroplasty surgery (popularly known as "stomach stapling").

Vascular stapler for reducing warm ischemia in organ transplantation. With this model each stapler end can be mounted on donor and recipient by independent surgical teams without care for reciprocal orientation, being the maximal possible vascular axis torsion ≤30°.

While devices for circular end-to-end anastomosis of digestive tract are widely used, in spite of intensive research circular staplers for vascular anastomosis never had yet significant impact on standard hand (Carrel) suture technique. Apart from the different modality of coupling of vascular (everted) in respect to digestive (inverted) stumps, the main basic reason could be that, particularly for small vessels, the manuality and precision required just for positioning on vascular stumps and actioning any device cannot be significantly inferior to that required to carry out the standard hand suture, then making of little utility the use of any device. An exception to that however could be organ transplantation where these two phases, i.e.device positioning at the vascular stumps and device actioning, can be carried out in different time, by different surgical team, in safe conditions when the time required does not influence donor organ preservation, i.e. at the back table in cold ischemia condition for the donor organ and after native organ removal in the recipient. This is finalized to make as brief as possible the donor organ dangerous warm ischemia phase that can be contained in the couple of minutes or less necessary just to connect the device's ends and actioning the stapler.

Although most surgical staples are made of titanium, stainless steel is more often used in some skin staples and clips. Titanium produces less reaction with the immune system and, being non-ferrous, does not interfere significantly with MRI scanners, although some imaging artifacts may result. Synthetic absorbable (bioabsorbable) staples are also now becoming available, based on polyglycolic acid, as with many synthetic absorbable sutures.

Titanium staples are not suspected of causing nickel reactions because nickel is rarely if ever used in titanium alloys.

Where skin staples are used to seal a skin wound it will be necessary to remove the staples after an appropriate healing period, usually between 5 and 10 days, depending on the location of the wound and other factors. The skin staple remover is a small manual device which consists of a shoe or plate that is sufficiently narrow and thin to insert under the skin staple. The active part is a small blade that when hand-pressure is exerted it pushes down on the staple and pushes it through a slot in the shoe and deforms the staple into an 'M' shape to facilitate its removal, although in an emergency it is possible to remove them with a pair of artery forceps. Skin staple removers are manufactured in many shapes and forms, some disposable and some reusable.
