Among various surgical instruments, vaginal speculums are one of the most versatile instruments used in gynecological procedures for visual examination of the vagina and cervix. The speculums come in different designs, sizes, and materials to suit various patient anatomies and specific clinical requirements. Surgitronix offers reusable stainless-steel speculums and modern disposable vaginal speculums to assist surgeons during surgery. From Pap smears to diagnosing infections to general reproductive health assessment, these tools are essential to ensure accurate screenings and promote women’s healthcare. This comprehensive guide will explore various types of vaginal speculum, how they differ, and how to choose the best option for your practice.
What is a Vaginal Speculum?
The vaginal speculums are essential gynecological instruments designed to be inserted into the vaginal canal to hold open the vaginal walls apart gently. This provides the gynecologists with optimum exposure and visibility of the vagina and the uterine cervix. They are primarily used to perform the following functions:
- Visualize the cervix and vaginal canal.
- Insert or remove intrauterine devices (IUDs)
- Collect cervical cytology samples (Pap smear)
- Conduct pelvic examinations and diagnosis.
- Diagnose infections or abnormalities.
- Perform colposcopy
Furthermore, these vaginal speculums are inserted directly into the vagina, and with proper use of their ergonomic handle, the blades open to dilate and enlarge the vaginal wall. This offers a clear view of the cervix for performing various procedures and diagnoses. The vaginal speculums are available in multiple shapes, sizes, and types to accommodate pelvic examination. Additionally, the main parts of the vaginal speculum include sharp blades, thumb-rest handles, a screw/ratchet locking mechanism, a hinge or pivot joint, and a single or double-blade configuration. However, these parts can vary depending on the type of speculum.

Types of Vaginal Speculums
The following are the primary types of vaginal speculums, categorized by design, which determines their function and the patient demographic for which they are best suited.
Graves Vaginal Speculum
The Grave vaginal speculum is the most common type of vaginal speculum that features broad, curved duck-bill-shaped blades, which have rounded distal ends. The wider blades of this instrument offer excellent visualization, making it a preferred choice in many general gynecology practices. They are highly recommended for routine pelvic exams, Pap smears, and assessments in women who have given birth multiple times. These grave vaginal speculums are available in standard, medium, and large sizes. Their key features include:
- Bivalve double-bladed design for self-retaining retraction.
- Curved/wider blade for optimal visualization.
- Screw locking mechanism for enhanced stability and control.
- Smooth, rounded edges to reduce inadvertent soft tissue damage.
- Available in multiple sizes to accommodate diverse patient anatomies.
Pederson Vaginal Speculum
The Pederson vaginal speculum is the most suitable type for patients with a narrow introitus, adolescents, or nulliparous women, postmenopausal patients with vaginal atrophy, and biopsies. The slender profile of this instrument makes insertion simpler and reduces discomfort for patients with limited tissue elasticity or smaller anatomy. Their key features include:
- Narrower, flatter blades reduce pressure and stretching of the vaginal walls.
- A slimmer profile for surgery on patients with vaginal atrophy and limited elasticity.
- Screw lock mechanism for self-retaining retraction and hand-free use.
- Blunt/smooth tips and curves for enhanced tissue protection.
- Available in multiple sizes to accommodate diverse anatomy.
Auvard Vaginal Speculum
The Auvard vaginal speculum is a weighted, single-blade instrument commonly used in surgical settings, including vaginal surgeries, labor and delivery procedures, and procedures requiring hands-free access. This instrument is typically connected to a weighted handle or hook that remains outside the patient, using gravity to pull the posterior vaginal wall back. Moreover, it’s ideal for opening the vagina for access to the uterus, cervix, vaginal wall, and uterine contents for various diagnostic and therapeutic purposes. Their key features include:
- Single, broad, curved blade for optimal posterior retraction.
- Smooth jaws and a blunt tip to minimize tissue trauma or damage.
- Long handle with an acute angle for improved surgical access.
- Variety of weights and blade sizes to accommodate patient anatomy.
- Weighted handle/detachable weight for self-retaining property.
Collin Vaginal Speculum
The Collin vaginal speculum is a double-bladed instrument with blades that are slightly broader laterally and less curved on the sides. These tools are preferred by surgeons for performing various procedures, including pap smears, cervical biopsies, and hysterography. Furthermore, the Collin speculums are designed to provide better retraction of the lateral vaginal walls, offering a wider view of the cervix. They are available in multiple shapes and sizes to suit all procedures. Their key features include:
- Broad, duck-bill-shaped blades for improved visualization.
- Hinged, double-blade design to suit all routine gynecological exams.
- Screw locking mechanism for self-retaining and hand-free use.
- Smooth outer curve to prevent accidental damage or injury.
Cusco’s Bivalve Vaginal Speculum
The Cusco bivalve vaginal speculum is mainly used to examine the cervix and vaginal canal, identify abnormalities, perform procedures like colposcopy and Pap smears, and assist with IUCD insertions. These tools feature smooth jaws that easily access and assist surgeons during vaginal and cervical examinations. Surgeons also use this type of speculum to gently remove tissue from the cervix when precancerous cells are detected, ensuring the procedure is painless. Their key features include:
- Bivalve, duck-bill design for effective and controlled retraction of the vaginal wall.
- Blunt, smooth working ends to reduce the risk of trauma or injury.
- Ergonomic handle design to provide optimal control and handling.
- Self-retaining mechanism to lock the speculum in place for hand-free operation.
- Available in different sizes for optimized patient comfort and fit.
Blade Variations in Vaginal Speculums
Vaginal speculums may also be classified according to the number of blades used for retraction. There are a single-blade speculum and a double-blade speculum, which are used to perform minor to complex procedures.
Single-Blade Speculum
The single-blade vaginal speculums are used to separate and retract only one anterior wall of the vagina at a time. These tools facilitate performing gynecological surgeries, laceration repairs, and procedures that require partial visualization.
Double-Blade Speculum
The double-blade speculums have a hinged design with two blades that are inserted closed and then opened and locked in place. These instruments are mainly used for Pap smears, pelvic examinations, IUD procedures, early postpartum checks, and other procedures. The double-blade speculums feature a locking mechanism that provides self-retaining retraction of both the anterior and posterior vaginal walls.
Disposable vs. Reusable Vaginal Speculums
Healthcare facilities must consider the advantages and disadvantages of materials when stocking their inventory. The reusable speculums primarily offer long-term economical benefits and a solid feel; however, they require sterilization protocols. On the other hand, the disposable versions are convenient and eliminate the risk of cross-contamination.
Feature | Reusable Vaginal Speculums | Disposable Vaginal Speculums |
Cost | High initial cost, low long-term cost | Low initial cost, high long-term cost |
Sterility | Proper cleaning and sterilization after each use. | Guaranteed sterile until the package is opened. |
Durability | Highly durable; lasts for many years | Single-use only |
Handling | Robust, heavy, and provides a tactile feel. | Lightweight, can sometimes feel less stable. |
