Everything There Is to Know About Surgical Instruments

Surgical instruments are tools or hand-held implements used by clinicians during the performance of operative tasks for functions such as dissecting, cutting, holding, grasping, suturing, or retracting. 

In an operating suite, a wide assortment of tools is available, facilitating a variety of operations and procedures. Clamps, scalpels, retractors, scissors, and forceps are in extensive use, but the nature of some operative procedures demands a more specialized collection of equipment. For example, bone saws, mallets, drills, and files serve in the department of orthopedic surgery. Incision tools are available in a range of sizes and made of stainless steel, carbon steel, titanium, or aluminum. Mainly the equipment falls in different working categories like grasping and holding, clamping, cutting and dissecting, probing, retracting, dilating, and suctioning.

History of Surgical Instruments 

The history of surgical instruments is as old as a human being can think. In France, ancient skeletons from the year 6500 BC have signs of trepanning. Ancient Egyptian frames have signs of surgery. To remove goiters and polyps, ancient Romans used some tools. In the Middle Ages, barber-surgeons were capable of removing stones from the bladder and cataracts from the eyes. Lack of knowledge about sepsis made most patients die from the infection. Without stainless steel or autoclaves, the earliest doctors used their fingers, teeth, and fingernails. Later, they started using sharp stones like flint, then steel and iron. The first use of fingers and teeth for surgery shaped the advanced equipment of today.

The 1920s, with disposable blades introduction of operative scalpels, occurred. They became a popular choice for reducing the risks of infection and maintaining sharpness. In the mid-20th century, vanadium, titanium, and chrome came into fashion for precision operative, hard-wearing, and lightweight appliances. Tools of titanium alloys made otological, neurological, and ophthalmological micro operative procedures possible. The late 20th electronic surgical instruments, like laparoscopic and endoscopic incision tools, arthroscopic shavers, ultrasound, electrocautery, electric operative scalpels, and other powered incision tools, came into practice. Surgeons saw the power of Computer-guided endoscopic surgery, so they became widespread for neurology, heart surgery, thoracic surgery, urology, and gynecology.

Indications to Use Surgical Instruments 

The surgical instruments can help in various domains:

Cutting, Incising or Dissecting 

They can be heavy-duty, like bone scissors, or they can be Metzenbaum scissors, with a thin, curved tip used on delicate tissue.

Grasping, Holding and Clamping 

Forceps pick up tissue such as bone holders or intestinal forceps. Forceps are scissor-like tools that hold things that may be too difficult to grasp with fingers. To control blood flow, clamps called hemostats are essential that compress the vessel. 

Retracting and Exposing  

Retractors keep the operative field open so the surgeon can access the operative pathology unobstructed.

Dilating and Probing 

The tools enter in a natural opening, like a bile duct. Or to provide access to a narrow passage, the instruments dilate or expand an opening. 

Suctioning and Aspirating  

Suction tips for micro operative procedures, gentle, temporary retraction, and provides controlled suction.

Suturing or Stapling 

After the operation, sutures reapproximate different types of structures to close a wound or re-join tissue.

Surgical Instruments in Dental Practice  

The functional, sterile, clean tool at the point of use and available in sufficient quantity at the right time are essentials of modern dental operative practice. The options for enhancing quality include using sterile items once, reprocessing through a local decontamination unit, or a sterile service department. Mostly there is no solution in which one size fits all while keeping the same end product of high quality; each practice will adopt a process best suited to its specialty and individual needs.

In Craniotomy, and Closure of Cranial and Spinal Wounds

Big tools are for the initial exposure, and finer ones are for the delicate structures. Various rongeurs remove soft tissue or bone. Dissectors facilitate isolation of a lesion, separate tissue layers. Aneurysm clips obliterate abnormal vascular structures. Scissors sharply separate soft tissue. Various sizes of cottonoids, protect delicate fibers and facilitate tissue dissection. Instead, using diuretics, skull base bony removal, proper head position, CSF drains, cistern opening can be implemented to expose the region of interest.

3D Printers for Surgical Instruments  

In warfare or conditions of natural calamity, cross-contamination or hospital-acquired infections are life-threatening. Acute shortage of sterile surgical appliances is common. In such emergency conditions, it is a challenge to find an appropriately sized tool. 3D printing technologies rescue by printing the nature of devices and are required as per the need. The making time of printed appliances is 90 minutes. They also have predictable stress-sustaining characteristic features. The advantage of using the high temperature-based 3D printing method makes the instruments sterile as soon as printed and ready for surgery use. 

Complications of Using Surgical Instruments 

Complications associated with the appliances are:

Improper Use or Technique by an Operator

Improper use of surgical instruments can contribute to post-operative complications.

Retained Instruments Inside a Person 

Depending on the type of tool and the location, it was left behind; serious complications arise with the retained instrument. Sometimes, these complications are fatal. However, even if no serious health complications occur right away, they can develop and become very serious. For example, sponge rots, when left inside the patient, results in pus and bacterial colonization, causing life-threatening ulceration. The ulcerations can rupture, rupturing leads to the infection spreading through the body. Sharp objects like blades and needles can puncture organs or blood vessels resulting in internal bleeding. The bleeding may go unnoticed for too long and may lead to a severe iron deficiency. Failure to adequately address the internal bleeding results in an infection, leading to sepsis. When there is a retained operative tool, additional surgery is usually required; this means more recovery time for the patient, costs, and health consequences. In addition to more surgery, patients may need IV medications and fluids. Sometimes, a blood transfusion is necessary.

Improper Sterilization  

Due to improper sterilization and cleaning techniques, they transmit infections or diseases. Improperly sterilized or cleaned appliances contribute to post-operative infections or mortality. 

General Specifications 

There are several designs of surgical instruments in the market, with different specifications, from the selection of chrome steels, corrosion-resistant, through manufacturing and heat treatment to finishing & final inspection. However, we are going to cite the general specifications.

•  Materials: Steel and some alloys like titanium or aluminum. 
•  CE certificates
•  High quality
•  Gamma radiation sterilization.

How They Work 

The working of each incision tool is different from the other, in general, for cutting and dissecting the tools to cut or separate soft tissue. Scissors cut the fibers, and dissectors may be sharp like scalpels or blunt like curettes and elevators. Forceps, tenacula, or clamps grasp and hold the tissues helping the professional to visualize better. Probing tools enter into natural openings, like a fistula or the common bile duct. Dilating appliances expand the size of an opening, like the urethra or the cervix. Suction devices remove fluids and blood from the invasive or dental field. Retracting appliances, while preventing trauma to other tissues, assist in the visualization of the operative field. The tools decrease the pre and post-operative work of health care professionals.

On the stand, the placement of the appliances occurs with a removable stainless-steel tray. The stands come in two styles: a two-wheeled version and an easily maneuverable four-wheeled version. The position is adjustable according to the desired height. Two dishes can be sterilized and prepared for use: first is an excision tray, and the other is a repair tray.

For efficiency and safety, the organization of the excision tray is significant. At the very least, the dish should contain a curette for debulking tumors, scalpel handle, tissue scissors, a ruler, forceps, and either a cup containing Gentian violet or a marking pen. Gentian violet delineates tumor margins. The excision tray should include a towel clamp and can transport specimens to the laboratory—Telfa pads more for holding sterile drapes. Cotton-tipped applicators are useful for hemostasis. The repair tray should contain almost the same items as the excision tray, alongside some additional specific appliances.
