When choosing a surgical stapler, several criteria must be taken into account, such as the type of surgery, the ergonomics of the device, its dimensions, and whether or not it is electric.

Goto Ezisurg to know more.

• Application: The type of surgery in which the stapler will be used
• Ergonomics: Comfortable handling, ease of use, audible trigger click, etc.
• Diameter and length: Staplers of different diameters and lengths are available on the market
• Suture length: The length of the wound to be sutured
• Thickness of the staples
• Articulation angle: There are articulated staplers with a rotation mechanism to guide the load and make it easier to apply staples in hard-to-reach areas; the articulation angle is adjustable
• Number of staples in the cartridge
• Electric or mechanical stapler: See the section on electric staplers

There are advantages and disadvantages to using surgical staplers compared to manual suturing with a needle and surgical thread. Here are the main ones below:

Advantages:

• Fast application and ease of use: Surgical staplers close large wounds or incisions faster. They are very useful in minimally invasive surgery as they only need a small opening and can quickly cut and join tissues and vessels.
• Lower risk of infection and less tissue reaction: staples offer faster healing.
• Resistant suture: Skin staplers are used to join skin with a strong tension, such as on the skull or torso.

Disadvantages:

• Less precision: Aligning the edges of the wound to be closed is less precise than when done manually.
• Higher cost: A surgical stapler and disposable staple cartridges cost more than a needle and surgical thread.

Electric staplers, or automatic staplers, run on batteries. They are still quite recent. According to a study funded by Ethicon (manufacturer of staplers, part of the Johnson & Johnson group) and published in the journal Advances in Therapy, compared to mechanical staplers, the use of electric staplers in a pulmonary lobectomy:

• Reduces the risk of complications (particularly bleeding)
• Shortens patients' recovery time by at least one day
• Reduces the cost of these procedures for healthcare establishments by around 10%

However, the study does not explain why electric staplers produced better results than mechanical ones. It may have something to do with the tissue gripping mechanism of electric staplers, but no evidence is presented in this regard.

Laparoscopic surgery, often referred to as minimally invasive surgery, has revolutionized the medical field. By using small incisions and specialized instruments, surgeons can perform complex procedures with greater precision, reduced risk, and quicker recovery times for patients. If you're a healthcare provider looking to equip your practice or hospital with laparoscopic instruments, understanding what to look for can help ensure you make the right purchase. This guide will walk you through the key factors to consider when buying laparoscopic instruments, so you can make an informed decision.

What Are Laparoscopic Instruments?

Laparoscopic instruments are specialized tools used in minimally invasive surgeries. These tools are designed to perform procedures inside the body with small incisions, typically between 0.5 to 1.5 cm, which minimizes scarring and reduces recovery time. Common laparoscopic instruments include:

Trocars and Cannulas: These create entry points for other instruments and allow for the insufflation of gas into the abdomen.

Single Port Trocars

Graspers and Forceps: Used for holding and manipulating tissues during surgery.

Scissors and Dissecting Instruments: Designed to cut tissue or sutures.

Sutures and Staplers: For closing internal incisions or stapling tissues together.

Disposable Skin Stapler

Endoscopes: Providing visualization inside the body via a camera attached to a long, flexible tube.

When selecting laparoscopic instruments, you want to ensure you're getting high-quality, durable tools that will support a wide range of surgical procedures.

Key Considerations for Buying Laparoscopic Instruments

Quality and Durability

Laparoscopic instruments are critical to successful surgery, so quality should be your top priority. Look for instruments made from medical-grade stainless steel or other high-quality materials that are resistant to corrosion and wear. Stainless steel instruments are known for their strength, sharpness, and longevity. Instruments should also be easy to clean and sterilize to maintain hygiene and prevent infections.

Before making a purchase, check the reputation of the manufacturer. Leading brands often invest heavily in research and development to ensure their instruments meet the highest medical standards.

Ergonomics and Comfort

Surgical procedures, particularly laparoscopic surgeries, often require long hours of concentration and precision. Instruments that are ergonomic and comfortable can significantly reduce fatigue and improve the surgeon's performance. Look for instruments with handles designed for a secure grip, as this helps reduce hand strain during long procedures. Some laparoscopic tools feature non-slip grips or adjustable lengths for better maneuverability and comfort.

Compatibility with Other Equipment

Laparoscopic surgeries typically involve a variety of instruments working together. It's important that the tools you choose are compatible with your existing surgical equipment, such as cameras, lighting systems, and monitors. For example, if you're using a specific brand of endoscope, ensure that the instruments you're buying will fit into the trocar or cannula used with that endoscope.

Variety and Versatility

Different types of laparoscopic procedures may require different instruments. Depending on the surgeries you intend to perform, look for a supplier who offers a comprehensive range of laparoscopic instruments. Instruments should be versatile enough to accommodate various procedures, from routine laparoscopic cholecystectomies (gallbladder removal) to more complex surgeries like colorectal resections or bariatric procedures.

A good supplier will offer instrument sets that include a variety of tools, such as scissors, forceps, needle holders, and graspers, in addition to specialized instruments for specific surgeries. Consider investing in instrument sets that are tailored for specific procedures, as this can help streamline operations and ensure you have the right tools on hand.

Ease of Maintenance and Sterilization

Laparoscopic instruments need to be sterilized thoroughly after each use to prevent cross-contamination between patients. Therefore, it is crucial to choose instruments that are easy to maintain, clean, and sterilize. Instruments should be designed to withstand repeated autoclaving, which is the most common method for sterilization in healthcare settings.

Additionally, the design of the instruments should minimize areas where bacteria or blood can accumulate. Look for instruments with smooth surfaces and minimal joints that can trap debris.

Cost-Effectiveness

While quality is the most important factor, the cost of laparoscopic instruments is another significant consideration, particularly for hospitals or clinics with tight budgets. While the cheapest options may seem attractive, they often lack the durability and performance necessary for optimal results.

Investing in higher-quality instruments may involve higher upfront costs but can save money in the long run due to the durability and fewer repairs needed. Some manufacturers offer warranties or service agreements, which can also add value by covering repairs or replacement parts over time.

The Buying Process

Research Reputable Suppliers

When purchasing laparoscopic instruments, it's essential to source them from a reputable supplier. Look for companies with a strong track record in providing high-quality, certified instruments. Check online reviews, ask for recommendations from other healthcare providers, and ensure the supplier complies with relevant certifications (e.g., ISO for medical device manufacturing).

Consider Customization Options

Some manufacturers offer the option to customize laparoscopic instruments for specific procedures or surgeon preferences. If your practice or hospital frequently performs certain surgeries, it may be worthwhile to inquire about customized instruments that are tailored to your needs.

Check for Product Warranties and Support

Many leading manufacturers offer warranties on their laparoscopic instruments, which can provide peace of mind. Be sure to ask about the warranty period and the type of support offered for repairs or replacements. A reliable supplier will provide excellent customer service and be available to assist in case of equipment malfunction or damage.

Test Before You Buy

If possible, test the laparoscopic instruments before purchasing them. Many suppliers will allow you to try out the instruments during a demonstration or trial period. This is especially important for instruments such as graspers, scissors, and forceps, as their handling and performance are key to the surgeon's ability to perform tasks accurately.

Conclusion

Investing in laparoscopic instruments is a significant decision that can directly impact the success of surgeries and the safety of your patients. By considering factors such as quality, ergonomics, versatility, and compatibility, you can ensure that your purchase will provide long-term value for your practice or hospital. Always buy from reputable suppliers, and don't hesitate to ask for recommendations and warranties to protect your investment. Whether you're outfitting a new surgical suite or upgrading your current equipment, following these expert tips will help you make an informed, confident purchase.
