Surgical Instruments

The Basics of Surgical Instruments

Because there are thousands upon thousands of different surgical tools, it is not surprising that many people find it particularly difficult to try to understand what each one is and what it is used for. However, once you learn that surgical tools are fundamentally categorised by the type of operation being performed and how they are utilised during that particular surgical process, things get a great deal simpler.

It is not in any way exhaustive or conclusive, and you can see how certain categories may overlap with one another. However, it will provide you with an overview of the interesting diversity of technologies that are at the disposal of modern medical practitioners.

Basic Types of Surgical Instruments and Their Applications

1. Stapling  and Suturing Surgical Instruments 

Instruments for suturing and stapling are used in surgery to close wounds by joining layers of skin and/or other soft tissues together. Suturing kits typically include suturing material, a needle, a needle holder, toothed forceps, and fine suturing scissors.

 Tungsten carbide jaws are used on instruments to prevent the needle from turning or twisting, increase the longevity of the instrument, and improve the user's grip and balance. Needle-protecting crosshatched serrations and smooth jaws are both useful, with the former utilised for smaller needles like those used in cosmetic surgery, and the latter for more robust procedures. 

Among the tools that fit this description are staplers and clip appliers. Terminal end, internal anastomosis, and end-to-end stapling are all possible using a stapler.

2. Cutting and Dissecting Surgical Instruments 

Surgical instruments for cutting and dissecting awide variety of Surgical instruments are used to cut skin, soft tissue, and even bones, and to dissect tissues along their anatomical planes. Some of these tools, like scalpels and blades, are one-time-use only, while others, like knives, can be used again and again.

Blades of varying sizes must be utilised in order to complete the various duties. Tonsillectomy is performed by otolaryngologists using blade 12, and large arteries like the aorta are punctured by vascular surgeons using blade 11. Blade 12 is used for tonsillectomy.

Metzenbaum scissors, which are used by plastic surgeons to cut intestinal mesentery, are constructed for cutting delicate tissues, whereas Mayo scissors, which are used by obstetricians and gynaecologists to cut ligaments, are meant for cutting robust tissues. Mayo scissors are used to cut ligaments.

Common instruments in this category include the bone curette, which is used by both neurosurgeons and orthopaedic surgeons during laminectomy during intervertebral disc procedures. Snares, bunches, blunt dissectors, Bone cutters, and biopsy forceps are also examples of instruments used in surgery for cutting and dissecting.

3. Retracting and exposing instruments 

Retractors help surgeons see more of the operating field by retracting and exposing devices. Using these tools, surgeons may safely pull out tissues without causing any damage. The Balfour abdominal retractor is one type of device frequently used in laparotomy for this purpose.

 The Army navy and the retractor are two further instances. The GELPI retractor is only one example of a self-retaining retractor that helps to improve visibility in the operating field. The sternotomy bone retractor known as a finocchietto is a crucial tool.

 Wide-flap dissection, as in a mastectomy or facelift, requires the use of hooks, such as skin, bone, or spays hooks, to retract skin margins. To reduce the risk of tissue damage, the points of certain of these hooks are rounded.

4. Grasping and handling surgical instruments 

Surgeons employ certain equipment to grab or hold tissues, allowing them a better view of their operating field. Forceps including smoothing forceps, toothed forceps, Allis forceps, tissue forceps, Babcock forceps, and stone forceps, tenaculum, and bone holds are the most common surgical devices used for this purpose

. General surgeons frequently employ rat teeth forceps, which are used to grab skin. Obstetricians use the Allis forceps for colporrhaphy and the Babcock forceps for grabbing intestine and towels anterior and posterior repair.

5. Dilating and probing instruments 

Dilating instruments are used to enlarge an opening, such as the cervical os or the urethra, whereas probing instruments are used to examine the area. Surgeons begin with a smaller dilator and work their way up to a larger one as they widen the opening.

 However, probes are used to examine areas that can only be accessed by natural openings, such as the urethra, vagina, and common bile ducts. Surgical probes can be used to listen to the urethra or the uterus, for instance.

6. Suctioning and aspiration instruments 

Instruments for suctioning and aspirating Blood and other fluids can accumulate in surgical and dental fields, making it difficult to see what's beneath the surface.

 Therefore, surgeons employ specialised equipment, such as the Poole abdominal tip used in laparotomy, the Frazier tip used in brain and orthopaedic operations, and the Yankauer suction tip used in oropharyngeal procedures, to drain these fluids from the surgical field.

7. Instruments for improving visualization  

Tools for better imaging: specialised equipment lets researchers peer inside otherwise inaccessible structures. Examples of such instruments are specula, endoscopes both hollow and lens endoscopes, anoscopesfor viewing the anus, and proctoscopes for viewing the anus and rectum.

8. Clamping and occluding surgical instruments 

Instruments for clamping and occluding tissue are primarily used to move blood arteries and other tissues out of the way during surgery. Hemostats, crushing clamps, hemostatic forceps, and non-crushing vascular cramps are all examples.

Surgical Instruments Maintenance & Disposable

Maintenance and disposal guidelines for surgical instruments:

Among the many types of medical equipment and supplies, surgical disposables are among the most widespread. Some items are designed to be used just once before being thrown away. There has been a steady rise, however, in the number of people who choose to reuse disposable items.

Infections can be transferred between patients and healthcare workers if surgical disposables are handled improperly.

As a result, stringent regulations regarding the use of surgical disposable items must be followed by all healthcare facilities. The laparoscopic and endoscopic instruments are particularly challenging to disinfect.

 Microorganisms may still be attached to instruments after thorough cleaning, even if medical facilities follow manufacturers' instructions.

Surgical instruments and supplies are sterilised in autoclaves, also called steam sterilisers. It aids in sterilisation by eliminating the need to store biohazard wastes near surgical instruments.

 In order for an autoclave to produce steam, the right kind of water must be used. While regular tap water can be used in a pinch, its high mineral concentration may prevent effective cleaning of surgical equipment.

After use, surgical disposables become biological waste. Because of this, they require special handling when being discarded. Here are some suggestions for properly discarding them.

- Discarded objects must be stored in a location where they won't be discovered by patients or staff.

- The disposal of biomedical waste should be performed only by trained professionals.

- To prevent confusion with regular trash, biomedical waste containers should be clearly labelled.

- The waste containers should be appropriately sized for the individual exam rooms in which they are located. As the number of patients in each bin decreases, doctors will be more      careful. When throwing away a specific kind of trash, you should use a specific can.
