Self-Retaining Retractors Buying Guide –  Tips for Hospitals & Clinics

Self-retaining retractors provide hands-free control of the tissues and other anatomical structures during a surgical procedure. With its efficient locking mechanism, a self-retaining retractor improves site visibility. However, it doesn’t require a surgeon to hold it. 

Grey Medical has prepared a buying guide dedicated to self-retaining retractors by including tips for hospitals and clinics. We will discuss its different types, key features, and common surgical procedures where we use them. Stay tuned!

What Are Self-Retaining Retractors?

A self-retaining retractor features a specialised lock fitted to hold the tissue and other anatomical structures in place. While hand-held retractors require active maneuvering, self-retaining retractors do not require any practitioner to hold it while procedure. Mostly, they find use in spinal, general, and neurological surgeries. 

Mode of Action and Function in Surgical Procedures

Generally speaking, the self-retaining retractor functions by inserting blades into a surgical site. Once the blades are inserted, they lock the tissue in place. In this way, the incisions and tissues remain stretched wide apart for better visibility. 

 

Mechanism: Usually, self-retaining retractors comprise two separate blades. These blades are placed in opposite directions. A common handle joins them. This handle has a locking mechanism, whereby it uses either a hinge or a ratchet. Once the retractor is in place, the blades move and turn, thereby retracting the surgical site. 

Difference Between Manual and Self-Retaining Retractors

Typically, a manual retractor requires a practitioner to continuously hold the tool in place for retraction. In contrast to this tool, a self-retaining retractor works on the principle of locking and fixation, where the blades fixate on the hinge, achieving retraction. This doesn’t require any active control or manipulation. 

Types of Self-Retaining Retractors

Given is a quick recap of different types of self-retaining retractors: 

Weitlaner Retractors

Known as the most common self-retaining retractor, the Weitlaner retractor usually helps retract soft tissues. Typically, it has two parallel blades, a blunt one in opposition to a sharp one. Mostly, there is a ratchet lock mechanism that keeps the tissues retracted at all times without any manual assistance. Additionally, the ratchet lock helps change retraction angles during stretching and retraction. This gives liberty to the surgeons for exploring different tissue angles. 

Gelpi Retractors

During deep and superficial surgical procedures, surgeons prefer using Gelpi retractors. Primarily, the instrument features two prongs, each curved outside. Due to the ratchet lock, the practitioners can achieve adjustable retraction. Mostly, spinal and orthopaedic surgeons find this retractor useful. 

Balfour Retractors

Surgeries like C-sections, laparotomies, and abdominal cavity use the Balfour retractor for pushing aside the abdominal walls. Structurally, it has three blades; one placed in the centre and two positioned sideways. The blades, usually, stay apart at a distance of 102mm to 250mm. This helps keep the tissues retracted at all times. 

Beckman Retractors

Whether it is a muscle or an organ waiting to be retracted, practitioners prefer using the Beckman retractor. Mostly, orthopaedic, spinal, and neurological procedures find this retractor useful in the surgical field. Furthermore, the blades are structured in a hinge-like form, which helps access deep cavities. 

Key Benefits of Using Self-Retaining Retractors

Note down the following key benefits of using self-retaining retractors. Precisely: 

Hands-Free Operation for Better Focus

The surgical site can be demanding, requiring undivided attention and active manipulation. Therefore, surgical supply stores have manufactured self-retaining retractors that do not need any practitioner to hold them. With their locks, screws, and ratchets, surgeons can manipulate the surgical site without actively holding the instrument for better visibility. 

Improved Visibility in the Surgical Field

Manual holding involves holding the instrument with one’s hands. Hands can hinder the view, resulting in discomfort. However, with self-retaining retractors, this concern is minimised. Self-retaining retractors provide 360-degree retraction, providing access to deep cavities. 

Reduced Staff Fatigue During Long Surgeries

OT staff can get tired due to active manipulation and holding instruments. With self-retaining retractors, surgeons experience reduced fatigue during long surgeries. Moreover, this helps surgeons remain focused during lengthy procedures. 

Features of High-Quality Self-Retaining Retractors

Get to know the key features of high-quality self-retaining retractors, such as:

Material and Durability

It’s a well-known fact that surgical-grade stainless steel is the best construction material for surgical instruments. Hence, we use only the best available in the market. Among the many benefits, it helps increase the longevity of the tools. 

Locking Mechanisms

All our self-retaining retractors come with specialised locking mechanisms. For example, we have locks, hinges, and screws. Once the retractor is in place, it keeps the surgical site retracted without any outside intervention. Furthermore, we make sure all our screws and hinges are well-constructed and in the right form for dependable functions. 

Smooth Edges and Precision Design

Since for retraction, the retractor has to be in direct contact with the tissues, organs, and walls, we make the retractor blades smooth. This assists in minimising any chances of accidental injury to the soft, healthy tissues. 

Modern Surgical Procedures Using Self-Retaining Retractors

Below is a list of modern surgical procedures that use self-retaining retractors for easy retraction, precisely: 

General Surgery

Different modern surgical procedures use different self-retaining retractors. For example, Laparotomy mostly uses Bookwalter, Balfour, or Golligher retractors. Similarly, for procedures like Thoracotomy, Bailey rib spreaders find usage. Additionally, different surgical intervention systems use other self-retaining retractors, such as during hernia repair, Appendectomy, etc.

Orthopedic Surgery

Usually, orthopaedic surgical procedures like Laminectomy, knee and hip replacement, and fracture reduction rely on self-retaining retractors. Mostly, Gelpi, Weitlaner, and Beckman-Adson retractors are used. Usually, these retractors have a compact design and form, allowing for deeper retraction. 

Gynecological Procedures

Mostly, gynaecologists make use of curved-edge self-retaining retractors to keep the abdominal wall and pelvic region open. Whether it is a Vaginal Hysterectomy or a Myomectomy, surgeons prefer using retractors like Balfour, O’Sullivan–O’Connor, or Javier-type. You can get your hands on these self-retaining retractors at our production unit. 

Neurosurgery Applications

Neurological structures are sensitive. Therefore, we have managed to construct equally sensitive and delicate self-retaining retractors like Adson cerebellar and Casper retractors, among others. Typically, these self-retaining retractors can be trusted with the retraction of dura mater and brain tissue, as these are minimally invasive.

FAQs

Q1: How to take care of your self-retaining retractors?

Once you are done with a surgical procedure, it is important to keep the self-retaining retractors in a facility that thoroughly makes it germ-free. Most importantly, the hinges, creaks, and screws should be properly disinfected so no complications surface in a surgical field. When cleaned, the retractors should be put in a storage case. 

Q2: What should the hospitals and clinics consider before buying self-retaining retractors?

Firstly, practitioners need to have a thorough knowledge of their surgical field. Every self-retaining retractor has different requirements. Therefore, it is important to do your homework so that you equip yourself with the necessary information regarding the configuration and size of the self-retaining retractor needed.
