Curette Biopsy Endometrial

Quick Answer: An endometrial biopsy curette is a slim instrument used to take a small sample of the endometrium, the lining of the uterus, for examination under the microscope. It is used in gynaecology teaching for instrument identification and for sampling practice on pelvic models.

Sampling Instead of Scraping the Whole Cavity

A diagnostic curettage under anaesthesia scrapes the whole uterine cavity. An endometrial biopsy takes only a small strip of the lining, often as an outpatient procedure, and sends it for histopathology. The instrument for this job is slim enough to pass through the cervix with little or no dilation. Metal patterns such as the Novak curette are narrow hollow tubes with a sharp-edged window near the tip, used with a syringe to draw tissue in; others have a small sharp scoop. Flexible plastic samplers such as the Pipelle work by suction from an inner piston and are widely used as single-use devices.

The listing does not identify the pattern of this curette; the image file name refers simply to an endometrial biopsy curette. Confirm whether it is a solid scoop or a hollow suction type before ordering, since the two are taught differently.

Students meet the instrument in obstetrics and gynaecology practicals, where they identify it and explain its indications, such as investigating abnormal uterine bleeding or assessing the endometrium during infertility work-up. LabEquip supplies it for teaching and does not claim regulatory approval for patient use.

Specifications

Applications

• Instrument identification in obstetrics and gynaecology examinations
• Explaining the work-up of abnormal uterine bleeding and infertility in tutorials
• Contrasting outpatient biopsy with full curettage using a uterine curette
• Pathology teaching on how endometrial samples are obtained before processing

Care & Handling

• Flush hollow curettes through immediately after use and clean the inside with a fine brush before sterilisation.
• Inspect the window or scoop edge under good light; a dull or burred edge tears tissue instead of cutting it.
• Store the curette in a tray or tube that protects the slim shaft from bending.

Why Choose LabEquip

Endometrial biopsy curettes are ordered by medical colleges and nursing schools completing gynaecology instrument sets, and by pathology departments that teach specimen handling. LabEquip lists the curette with the dilation and curettage set in its Biology Lab Products range.

Frequently Asked Questions

What is the difference between an endometrial biopsy and a D and C?

An endometrial biopsy takes a small sample of the lining, usually without anaesthesia or much dilation. A D and C dilates the cervix and scrapes the whole cavity, usually in an operating theatre.

How does a Novak curette take a sample?

It is a hollow tube with a sharp-edged opening near the tip. A syringe on the handle end creates suction that draws the lining into the opening, and moving the curette cuts a strip of tissue.

How is a metal biopsy curette different from a Pipelle sampler?

The metal curette is reusable after cleaning and sterilisation. A Pipelle is a flexible plastic tube with an inner piston that creates suction, and it is discarded after one use.

Why is the sample sent for histopathology?

The pathologist examines the tissue under the microscope to assess the phase of the cycle, hyperplasia, infection or cancer, which cannot be judged by eye.

Does an endometrial biopsy need cervical dilation?

Usually not, because the instrument is slim. A small amount of dilation may be needed if the cervical canal is narrow.

How should the curette be cleaned?

Rinse it straight away so tissue and blood do not dry inside, clean the lumen and tip with a narrow brush, then sterilise and dry it before storage.
