Punctures are often essential for the diagnosis of certain diseases. Various puncture instruments are used to aspirate fluids, tissue or cellular material. In a puncture set, all important components such as puncture cannulas, catheters or disposable syringes are included.
What is a puncture kit?
In a puncture set, all important components such as puncture cannulas, catheters or disposable syringes are included. In medicine, a puncture refers to the targeted insertion of a hollow needle (cannula/trocar) into the body to aspirate pathological fluid accumulations or to remove tissue samples as part of a fine-needle biopsy. Gas accumulations in the intestines can also be drained with the help of a puncture. Venipuncture is one of the most commonly used forms of puncture. On the one hand, this method is used for blood sampling and on the other hand, it is used for intravenous injections. To obtain puncture specimens from organs, joints, arteries or tissue, physicians use a sterile puncture set that contains all the important tools for puncturing. The medical trade offers various systems for joint punctures, lumbar punctures or liver punctures. Puncture sets differ in terms of their composition and are available with different sampling systems. In addition to the puncture needle and disposable syringe, a medical puncture set for pleural puncture includes other components such as a transfer tube, check valve, connector, suction tube and secretion bag. Check valves, for example, prevent body fluids that have been removed from the puncture from flowing back. Pleural puncture sets are used in emergency medicine, for example. In addition, a puncture set for diagnostic or therapeutic use is often equipped with additional medical materials such as compresses, bandage clamps or anesthetics.
Shapes, types and styles
The medical professional chooses the appropriate puncture set depending on the type of puncture. The sets, which come in a variety of designs, can be supplemented with other medical products, such as collection containers, disinfection solutions or puncture wipes. Puncture needles are available in various sizes and allow flexible use, for example for pressure injections. A modern puncture set with puncture cannulas such as hollow needles or fine needles and innovative puncture accessories ensures safe execution with maximum patient comfort. Color-coded transfer tubes or printed dressing clamps allow quick differentiation from other aids. Foldable safety arms guarantee effortless removal of puncture needles and protect against needlestick injuries. For percutaneous renal puncture, cannulas with hollow trocar are available in addition to puncture needles with trocar cut, which allow precise guidance during puncture. Cannulas with perforated catheters can be used simultaneously for drainage or puncture of cysts. For sampling cerebrospinal fluid (nerve fluid) during a lumbar puncture, physicians use a special puncture set with extra-fine spinal needles. For short-term infusions, venipuncture sets with particularly slippery cannulas and integrated cannula protection sleeves that provide optimal grip during puncture are suitable.
Design and mode of operation
Innovative catheter and needle devices for puncture are offered as standardized and advanced systems. Puncture sets with puncture needles, trocars, guide needles, suction tubes and stopcocks are equipped with state-of-the-art technology for all puncture methods. A trocar is a medical instrument that provides access to a cavity in the human body, such as the abdominal or thoracic cavity, in minimally invasive surgery. A tube holds this access open so that the physician can insert surgical instruments or high-resolution optics into the body cavity. Trocars are available in various lengths and diameters. Cannulas in the puncture set are used to penetrate the body tissue and either withdraw fluids or inject them into the tissue. Mono-cannulas or triport cannulas are offered with a wide range of connection variants for a wide range of applications. Special cannulas are often used in biopsy for taking tissue samples. Guide needles bridge the path to the tissue sampling site or assist the user in inserting very fine puncture needles.In addition to cannulas and trocars, a puncture set also includes ampoule syringes and glass cylinder syringes. For aspirating body fluids, physicians often use a suction tube. Individual suction heads or suction olives can be ordered to complement these puncture instruments. Puncture accessories such as stopcocks or connectors for infiltration are used to shut off or divert flow. Puncture and drainage systems with spring-loaded obturator and self-locking valve are suitable for short-term patient care. In these systems, a red color change signals the exposure of the sharp tips. Cyst obturators are commonly used in dentistry, for example, to prevent occlusion of a cyst in the jaw.
Medical and health benefits
In medicine, there are a variety of puncture types for diagnostic and therapeutic uses. Physicians use an arterial puncture to obtain blood to perform a blood gas analysis. Especially in critically ill patients, an indwelling arterial catheter facilitates repeated blood sampling and accurate blood pressure measurement. In patients with pathological fluid accumulation in the abdominal cavity, the physician can use an ascites puncture to drain fluid and simultaneously identify the trigger of abdominal dropsy. For this purpose, the physician uses a puncture set with a fine puncture needle, which he places with the help of an ultrasound device in order to avoid intestinal injuries. Tissue sampling is one of the diagnostic puncture methods and is mainly used in cases of suspected cancer. Filigree hollow needles and special syringes are used to remove tissue or cells. If prostate cancer is suspected, punch biopsy is a common procedure. However, the puncture set contains a much thicker hollow needle, which is usually inserted very quickly into the suspected body site. A joint puncture relieves pain, which is caused in particular by strong pressure. Using a puncture needle, the physician can aspirate blood or pus with a syringe, but also inject medication into the joint cavity. The drained joint fluid is then examined in the laboratory for pathogens. Before each puncture, the doctor has a detailed discussion with the patient and explains the risks and side effects. Side effects of a lumbar puncture include, for example, temporary headaches. In general, during punctures, pathogens can also get inside the body via the puncture needle or bruises can form at the puncture site. To reduce the risk of side effects, physicians use only special puncture sets and often puncture with the aid of imaging techniques such as ultrasound.
