Biopsy instruments are medical tools designed for the collection of tissue samples from the body for diagnostic purposes. These samples are typically examined under a microscope to aid in the diagnosis of various medical conditions, such as cancer or inflammatory diseases. Different types of biopsies may be performed depending on the suspected condition and the location of the tissue in question. Here are some common biopsy instruments:
Biopsy Needle:
Fine Needle Aspiration (FNA) Needle: Used for sampling small tissue masses, such as those found in the breast, thyroid, or lymph nodes.
Core Biopsy Needle: Extracts a small, cylindrical core of tissue for more detailed analysis, commonly used in breast or prostate biopsies.
Biopsy Forceps:
Endoscopic Biopsy Forceps: Used during endoscopy procedures to collect samples from the gastrointestinal tract or other internal organs.
Punch Biopsy Forceps: Employed for obtaining small, circular tissue samples, often used in dermatology.
Biopsy Punch:
Similar to punch biopsy forceps, these instruments are used in dermatology and involve a circular cutting tool to remove a small disc of tissue.
Brush Biopsy:
A brush is used to collect cells from the surface of tissues, commonly employed in the diagnosis of certain cancers, such as lung cancer.
Curettes:
Endometrial Curette: Used for obtaining samples from the lining of the uterus.
Bone Curette: Employed in bone biopsies to collect samples for analysis.
Vacuum-Assisted Biopsy Devices:
Utilizes suction to extract larger tissue samples, often used in breast biopsies.
Trocar and Cannula:
Employed in procedures like bone marrow biopsy, where a trocar is used to puncture the bone and a cannula is inserted to extract a bone marrow sample.
Biopsy Gun:
Often used in core needle biopsies, a biopsy gun allows for the rapid collection of tissue samples with minimal invasiveness.
