Medical needles – Reliability and precision for injections

Medical needles

The injection needle consists of a metal cylinder with a sharpened end and a head ( cannula ) attached to a syringe or system. The cannula necessarily has "flats" (parallel surfaces for holding the needle), mostly square or rounded.

Features of choice

The design of the needle is very diverse. Its tip extends from the advanced end of the needle to the maximum cross section of the body. Depending on the type of tissue, disposable needles vary in sharpness, so they can easily penetrate it. Choosing needles for syringes, pay attention to their quality and raw materials used in production. Whether you need a thin or thick syringe needle, you will find a full range of sizes in the TUFISHOP online store. The company makes sure that the products presented in the assortment come only from trusted manufacturers.

Types of medical needles

Conventionally, the needle can be divided into several forms: cutting and stabbing, taperkat, blunt, and lanceolate. Each type has its own characteristics:

• Stitching . The shape of the cylinder in cross section, as well as conical at the end of the needle. They are used mainly for internal organs: anastomoses are applied, homogeneous tissues are connected.
• Cutting . Three-sided shape. They are used for stitching dense skin tissues. They have a trihedral shape in cross section.
• Taperkat . This is a combination of two needle functions of the first and second kind. Used for stitching hard tissues.
• Lanceolate . It has the shape of a trapezoid with two pointed ends. Penetrates between thin layers of tissue, but does not damage them. Used in areas where extreme care is needed: ophthalmology, microsurgery.
• Dumb-ended . These needles are round in shape with a blunt end. Suitable for stitching the liver or cervix.

How to choose the right needle

A medical needle is a hollow metal rod that is used to administer injections or collect and transfer samples.

Medical needles for sampling

These needles are designed for two main types of analyses:

Blood sampling: When puncturing a vein or artery, a tourniquet may be required to expose the vein. Some blood collection or infusion needles are equipped with a pre-assembled tube adapter.

Biopsy: Most biopsy needles are extremely thin and strong, such as a lumbar puncture needle. The needle penetrates deep into the intervertebral space of the lumbar spine and pierces the dura mater, the fibrous membrane that protects the spinal cord. In this way, a sample of cerebrospinal fluid is taken, which allows to detect the presence of diseases such as bacterial meningitis. This procedure is performed under local anesthesia.

Injection medical needles

There are two main types of injections for this kind of needles:

Hypodermic needles: These allow the drug to be administered by injection into the patient's subcutaneous tissue. This type of injection can be performed in hospitals, clinics, nursing centers, and even at home. Needles are used with a prepared syringe. There are special devices called syringe pens that allow you to easily and accurately adjust the dose for injection. In this case, the drug is presented in the form of pre-filled cartridges, due to which the dose does not need to be measured from the vial. The needle must be replaced after each use. These needles are commonly used to inject insulin or certain anticoagulants.

Intravenous needles: These allow you to inject a liquid, often a drug solution, directly into a vein. For this, a tourniquet is used, which is applied 10 centimeters above the injection site. Intravenous injections provide a faster therapeutic effect than subcutaneous injections. It also avoids the risk of reactions with subcutaneous or muscle tissue (pain, swelling or in extreme cases even necrosis).
