What are vaginal speculums and when are they used?

A vaginal speculum is the single most used instrument in gynaecology. Clinicians rely on it for cervical screening (smear tests), coil (IUCD/IUS) fittings, swab collection and visual assessment of the vaginal walls and cervix. The instrument holds the vaginal canal open so the practitioner has a clear view and both hands free.

In the UK, the move towards single-use disposable speculums has accelerated. Disposable models eliminate the need for autoclaving, cut cross-contamination risk and simplify stock management. Most NHS trusts and GP surgeries now specify disposable Cusco-type speculums as standard.

Key features to compare when choosing a speculum include the locking mechanism (click-lock vs screw), blade width and length, material clarity for visibility, and whether the design minimises skin pinching during use.

Cusco Vaginal Speculum

The Cusco Vaginal Speculum is the classic choice. Vena Cava supplies these in four sizes (XS, S, M, L) at just £18 per pack of 25, making them one of the most cost-effective options on the market. Each unit is individually wrapped, sterile and features a secure locking mechanism for one-handed operation.

ComfiSpec Disposable Speculum

The ComfiSpec range is designed with clinician comfort in mind. A textured handle gives a confident grip, while the 38-degree opening angle and fast-acting lock reduce the steps needed during an examination. The anti-pinch blade edges help minimise patient discomfort. Available in small, medium and medium-long sizes at £29.99 per pack of 25.

How are cervical sampling brushes used in screening?

Cervical sampling brushes collect cells from the cervix during the NHS Cervical Screening Programme (smear tests). The brush is rotated gently against the cervix to gather both ectocervical and endocervical cells, which are then processed using liquid-based cytology (LBC).

The choice of brush matters. A well-designed sampler captures an adequate cell yield on the first pass, reduces the rate of inadequate samples and minimises patient discomfort. Two main types are used in UK practice:

Cervex Sampling Brush: The industry-standard broom-type device. Vena Cava stocks the Cervex Sampling Brush (sterile, pack of 100) at £62.99 and the non-sterile pack of 25 at £17.49. The Rovers Cervex-Brush has a proven track record in NHS screening programmes.

Cervibrush+ LBC Endocervical Sampler: Features a hexagonal handle for effortless rotation and a secure brush head. Available in packs of 10 (from £5.99) and 100 (£36.99). The Cervibrush+ Profile variant collects from both the ectocervix and endocervix simultaneously, reducing the need for two separate samplers.

What are cervical dilators and when are they needed?

Cervical dilators gradually widen the cervical os to allow access for procedures such as IUCD/IUS insertion, hysteroscopy, endometrial biopsy and evacuation of retained products of conception (ERPC). The most common type in UK practice is the Hegar dilator, a double-ended, tapered instrument available in graduated sizes.

Hegar dilators are numbered by their diameter in millimetres. A typical set runs from sizes 1/2 through to 11/12, though most routine procedures (such as coil fitting) only require sizes 3/4 to 7/8. For clinics performing frequent IUCD fittings, keeping sizes 3/4 and 5/6 in stock covers the majority of cases.

Vena Cava stocks both the Instrapac single-use Hegar Dilators (from £2.78 each) in surgical stainless steel, and the Rocialle Hegar Dilators (from £1.99). Both are supplied sterile and individually packaged.

What role do sponge holders and forceps play?

Rampley sponge-holding forceps are used to hold swabs or gauze during cervical and vaginal procedures. They are essential for applying antiseptic solution to the cervix before IUCD insertion or colposcopy, and for gently manipulating the cervix during examinations.

Vulsellum forceps (tenaculum forceps) grasp the cervix to provide traction and stabilisation during procedures such as coil fitting and endometrial biopsy. These instruments are available in both reusable and single-use formats.

For clinics preferring disposable options, the single-use instruments in Vena Cava's single-use instruments collection provide a convenient, sterile-packed alternative that eliminates reprocessing.

How do IUCD fitting kits simplify coil insertion?

An IUCD (intrauterine contraceptive device) fitting requires multiple instruments: a speculum, sponge holder, vulsellum forceps, uterine sound, cervical dilators, scissors and a gallipot. Gathering each item individually takes time and increases the risk of forgetting a component.

Pre-assembled IUCD fitting packs solve this by bundling every instrument into a single sterile tray. This approach speeds up clinic preparation, ensures nothing is missed and simplifies stock ordering.

For higher-volume clinics, the ComfiKit Premium IUCD Fitting Pack (£21.99) includes upgraded components. Cases of 10 are also available for practices running regular coil clinics.

When are pessaries used and how do you choose the right type?

Pessaries are silicone devices inserted into the vagina to support pelvic organs in women with pelvic organ prolapse (POP). They are a first-line, non-surgical treatment option and are fitted by trained clinicians in GP surgeries, urogynaecology clinics and community settings.

The two most common types are ring pessaries (suitable for mild to moderate prolapse) and Gellhorn pessaries (for more advanced prolapse where a ring does not provide sufficient support). Sizing is critical, as an incorrectly fitted pessary can cause discomfort, displacement or vaginal erosion.

Vena Cava stocks the Milex Silicone Ring/Folding Pessary range (from £80.99) in multiple sizes, as well as Gellhorn and cube pessaries. For a deeper dive into pessary types, sizing and management, read our Comprehensive Guide to Pessaries.

Why is the right lubricant important for gynaecological examinations?

A water-based, non-spermicidal lubricant is essential for patient comfort during speculum examinations, bimanual pelvic examinations and device insertions. Using the wrong lubricant can interfere with cytology samples or damage latex devices, so product selection matters.

For cervical screening, many trusts specify that lubricant should be applied only to the outer blades and not to the tip, to avoid contaminating the cell sample. Water-based gels such as PELIjelly are compatible with LBC processing.

How should gynaecology instruments be disinfected?

Single-use instruments are disposed of after each patient, but reusable items (such as metal speculums or stainless-steel dilators) and semi-critical devices like ultrasound probes require high-level disinfection between uses.

The Tristel Duo ULT Foam (£213.49) is a chlorine dioxide-based, high-level disinfectant approved for use on transvaginal and transrectal ultrasound probes. It is widely used across NHS trusts because it achieves sporicidal disinfection without the need for an automated reprocessor. For a detailed look at the disinfection process, see our guide on high-level ultrasound disinfection with Tristel.

How to choose the right gynaecology instruments for your clinic

Selecting instruments is not just about price. Here are the practical factors UK clinicians should consider:

1. Match instruments to your services. A GP surgery running a weekly smear clinic needs speculums and sampling brushes in volume. A sexual health clinic offering IUCD fittings needs dilators, sponge holders and vulsellum forceps too. Start with the procedures you perform, then build your stock list from there.

2. Stock multiple sizes. A single speculum size will not suit every patient. Keep at least small, medium and large speculums on hand, and consider stocking XS for patients who find standard sizes uncomfortable. The same principle applies to pessaries and dilators.

3. Weigh up single-use vs reusable. Disposable instruments cost more per unit but eliminate autoclaving costs, reduce cross-contamination risk and simplify compliance with clinical waste management requirements. For high-throughput settings, the total cost of ownership often favours single-use products.

4. Consider pre-assembled kits. If your clinic performs the same procedure repeatedly (for example, IUCD fittings), a pre-packed kit like the ComfiKit saves preparation time and ensures consistency.

5. Verify compatibility with screening pathways. Cervical sampling brushes must be compatible with your laboratory's LBC processing system. Check with your lab before switching brands.

Frequently asked questions

What instruments do you need for a cervical smear test?

A standard cervical screening requires a disposable vaginal speculum (typically Cusco-type, medium), a cervical sampling brush (such as the Cervex-Brush or Cervibrush+), an LBC specimen vial and a water-based lubricant. Some clinicians also use a light source attached to the speculum for improved visibility.

What is included in an IUCD fitting pack?

A typical IUCD fitting pack contains a vaginal speculum, Rampley sponge-holding forceps, vulsellum (tenaculum) forceps, a uterine sound, cervical dilators, scissors, a gallipot and a drape. Pre-assembled packs such as the ComfiKit include all of these instruments in a single sterile tray.

Are single-use speculums better than reusable metal ones?

Neither is universally "better." Single-use plastic speculums eliminate the need for autoclaving, reduce infection risk and offer a lower upfront cost per unit. Reusable metal speculums offer more rigidity, which some clinicians prefer. For most UK GP surgeries and clinics, single-use disposable speculums are now the standard because they simplify infection control compliance.

What sizes of vaginal speculum should a clinic stock?

Most clinics should carry at least small, medium and large. Medium is the most commonly used size. An extra-small option is helpful for patients who find standard sizes uncomfortable, and medium-long speculums are useful for patients with a higher BMI or a posteriorly positioned cervix.

How are transvaginal ultrasound probes disinfected between patients?

Transvaginal probes are classified as semi-critical devices and require high-level disinfection. The most widely used method in UK settings is a chlorine dioxide-based foam such as Tristel Duo ULT, which achieves sporicidal kill without an automated reprocessor. Always follow the probe manufacturer's guidance and your trust's decontamination policy.
