Endoscopy scissors are surgical instruments used for cutting tissue in minimally invasive procedures. They are designed to work with an endoscope, a camera inserted into the body through small incisions or openings. The following are the primary types of endoscopic scissors:
Metzenbaum Scissors:
These scissors have long handles and short, rounded blades, making them ideal for cutting delicate tissues. Their design permits the precise dissection of fine tissues without causing damage to surrounding areas.
Dissecting Scissors:
These are surgical scissors used to cut and dissect tissues. They have a blunt tip on one blade to protect adjacent structures from inadvertent injury during dissection.
Cap Scissors:
These grasping instruments with blades that open and close like scissors are designed for cutting caps or flaps during endoscopic procedures.
Suture Scissors:
These have a special notch on one blade that helps lift sutures for easy cutting. Their design makes them suitable for precision suture cutting without causing harm to surrounding tissues.
Curved Scissors:
These are curved, pointed, or delicately rounded at the tips, like the curved Metzenbaum scissors. Their design permits access into tight spaces within the body where straight scissors cannot reach adequately.
Radial Jaw Scissors:
These are a lot like radial jaw forceps. Their jaws open out instead of up, allowing them to reach deeper inside the body. They are frequently used in endoscopic procedures to cut and grasp tissues accurately.
Type of Procedure:
The type of procedure dictates the selection of endoscopy scissors. For example, blunt dissection scissors are used for blunt dissection and controlled tissue division. Cold biopsy forceps are used for obtaining biopsy samples. Laser scissors are used in laser surgery, while electrosurgical scissors are used in electrosurgery.
Tissue Type:
The type of tissue being cut also influences the choice of scissors. Sharp, precision cutting may be required for delicate tissues like mucosa. For tougher tissues or fibrous tissues, tougher blades may be needed. Understanding the tissue type helps in selecting the right tool for the procedure.
Access and Visualization:
Scissors with angled blades or elongated handles may be needed in cases where access to the surgical site is limited or where optimal visualization is required.
Ergonomics:
The ergonomics of the scissor are important, especially in a lengthy surgical procedure. Scissors with comfortable handles, good grip, and excellent balance can reduce fatigue and improve precision in cutting.
Compatibility with Endoscope:
All endoscopy scissors must be compatible with the endoscope being used in the procedure. The diameter of the shaft must fit the endoscope's working channel, and the design should allow proper maneuverability inside the anatomical structures.
Quality and Reliability:
Endoscopy scissors should be of high quality and durable. The material should be strong enough to withstand the procedure, and the scissors should be calibrated to ensure precision cutting. The sharpness of the blade, the alignment, and the locking mechanisms are important factors to check before every surgical procedure.
Cost and Budget Considerations:
High-quality scissors are expensive but well worth the investment. Scissors are single-use, so the cost will be determined by the number of uses the scissors are designed for. Consider all the above factors before looking at the price; the quality of the instrument is paramount, and the price should come last.
Endoscopy scissors are used during endoscopic procedures. The general steps for using these scissors are as follows:
Preparation
The surgeon prepares for the procedure by reviewing the patient's medical history and imaging studies. They gather the necessary equipment, including endoscopy scissors, and administer anesthesia to the patient.
Insertion of Endoscope
The surgeon inserts the endoscope, a long, flexible tube with a camera and light, into the patient's body through the mouth, nose, or incision site. They visualize the area of concern on a monitor.
Accessing the Target Area
The surgeon uses the endoscope to navigate to the location of the issue, such as a tumor, polyp, or damaged tissue. They may encounter obstacles like scar tissue or other structures that need to be cleared to reach the target.
Using Scissors
Once at the target area, the surgeon uses the endoscopic scissors to cut tissue or structures. They manipulate the scissors with precision using hand controls on the endoscope. Actions include opening/closing the blades to grasp and cut tissue. Common motions are snipping, slicing, or pulling to remove or sample the tissue.
Controlling Bleeding
The surgeon controls any bleeding from blood vessels in the area. They may use cautery forceps or bipolar cautery to coagulate and close vessels as they cut. Maintaining a clear surgical field is essential for visibility and safety.
Completion
The surgeon completes the cutting task, whether excising a tumor or biopsying tissue. They withdraw the scissors and endoscope from the body. They may suture any incisions or recover the patient from anesthesia. The tissue specimens are sent for pathology examination, and the medical team discusses the findings and next steps.
Regular Sterilization
Manufacturers make endoscopy scissors from materials that are easy to sterilize. They ensure that the scissors are free from harmful microorganisms by following strict guidelines for their sterilization.
Quality construction
Every endoscopic scissor goes through rigorous quality control during its manufacturing. The process ensures that every pair of scissors meets the highest safety standards. All endoscopy scissors have a solid construction that can withstand the rigors of use without compromising safety or performance.
Compliance with safety standards
Every endoscopy surgical instrument is made following the required safety standards and regulations. The compliance ensures that the scissors meet the essential requirements for quality, safety, and performance.
Clear visibility
Endoscopy scissors are designed with clear and sharp cutting edges. This visibility allows the user to see the tissue being cut accurately. No part obstructs the view, and the surgeon makes precise cuts without damaging surrounding tissues.
Function:
Endoscopic scissors are used to cut tissues during endoscopic surgery. Surgeons use these scissors to grasp and cut tissues such as polyps or tumors for biopsy or removal. The scissors have hand controls that open and close the cutting blades. The long shaft allows access to narrow inside body parts. The small, precise tips cut tissues with little bleeding. Some models have forceps grips to grasp tissue before cutting. The scissors come in various sizes and blade shapes to suit different procedures. Their small size and precise cutting allow surgeons to remove growths from the digestive, respiratory, and other systems with minimal invasions.
Features:
Endoscopic scissors have features that aid precise cutting of tissues in confined body spaces. They have a long, thin shaft to reach deep inside. Their small, precise tips cut tissues with little bleeding. Most models have hand controls near the shaft, which open and close the blades. This gives surgeons precise control at the incision site. Some scissors have forceps grips to hold tissue before cutting. Scissors are available in various sizes, blade shapes, and shaft stiffness. This allows selection for specific procedures. Their design enables them to dissect tissues, remove polyps, or take biopsies during minimally invasive surgeries.

Q1: What material is used to manufacture endoscopic scissors?
A1: Endoscopic scissors are made of high-grade stainless steel. This material is strong and durable. Scissors made from this material will serve medical practitioners for a long time.
Q2: What are the sizes of endoscopy scissors?
A2: The sizes of endoscopic scissors vary depending on the type. For example, Micro scissors have a jaw length of 5 mm. The jaw length of curved scissors under the micro category is between 5 mm and 8 mm. Biopsy scissors have a jaw length of 5 mm to 15 mm.
Q3: How to maintain endoscopy scissors?
A3: Endoscopic scissors should be cleaned thoroughly after every use. Every medical practitioner should follow the manufacturer's guidelines for cleaning the scissors. The scissors' locking mechanism, blades, and joints should be checked regularly. Any signs of wear and tear should be noted. The scissors should be stored in a protective case to avoid any damage.
