Product catalog summary

Aspiration Procedure
A detailed procedure for bone marrow aspiration using a biopsy needle is outlined. The patient is positioned either prone or in a decubitus position, with the posterior iliac crest being the common site for obtaining bone marrow. The skin is cleaned with antiseptic, and local anesthetic is injected. A skin incision is made, and the needle is inserted through the incision into the bone marrow cavity by rotating it. A syringe is connected to apply suction and collect the specimen. The procedure is repeated for biopsy collection using the same incision but a different location.

Biopsy Procedure
The biopsy procedure follows similar initial steps as the aspiration procedure, with additional steps for obtaining an adequate marrow sample and checking the sample length using a blunt stylet.

Equipment Description
The document describes the components of the biopsy needle: the cannula, cannula hub, aspiration hole, sharp stylet, and blunt stylet. Each component has a specific function in the procedure, such as drilling holes, collecting specimens, and pushing specimens out.

Bone Marrow Function
Bone marrow is responsible for producing red blood cells, white blood cells, and platelets. Biopsies are ordered when there are issues with blood cell production or to monitor treatment progress in blood-related cancers.

Model Information & Specifications
Specifications for different models of the biopsy needle are provided, detailing the length and diameter of the cannula, sharp stylet, and blunt stylet.

Indication for Use
The ColexTM Bone Marrow Biopsy Needle is intended for harvesting bone and/or bone marrow specimens.

Advantages and Features
The procedure is minimally invasive, with low risk and quick recovery. The device features an aspiration hole for easy collection and is available as an all-in-one disposable kit.

Catalog excerpts

Place the patient in either Prone or Decubitus position. Posterior iliac crest is the most common side to obtain bone marrow. Clean the skin with an antiseptic solution Inject the marked area with local anesthetic to the periosteum. Make a skin incision with a scalpel blade over the marked area. Insert the needle (combining Cannula with Sharp stylet) through the incision. By rotating the needle, put the needle gently through the periosteum into the cortex. Remove Sharp stylet by rotating upper section of handle and pulling straight out. By rotating the Cannula needle, continue putting the Cannula needle forward into the bone marrow cavity. The marrow cavity is generally detected by decreased resistance. Connect the syringe to Cannula hub. Apply suction by withdrawing syringe plunger. Remove the syringe collecting the aspirated specimen. Remove the Cannula from body slowly. BONE MARROW Take the biopsy after the aspiration using the same skin incision, but choosing a different location to obtain the biopsy sample. Repeat Steps A through I of the procedure and continue as follows: J By rotating the Cannula needle (for better cutting), slowly and gently putting the needle until adequate marrow is obtained. Step-A K Insert the Blunt stylet into the Cannula to check the sample length in the Cannula. L Remove the Blunt stylet. M Remove the Cannula from body slowly, and push the specimen out with the Blunt stylet. Step-K COLEX COLEX Bone Marrow Biopsy Needle

COLEX COLEX What is bone marrow? Aspiration Hole Bone marrow produces red blood cells, white blood cells, and platelets. Bone marrow is the soft tissue that is inside most large bones. Bone marrow makes a lot of the body's blood cells, including red blood cells, white blood cells, and platelets. Why do a bone marrow biopsy? Sharp Stylet Blunt Stylet Health providers order bone marrow biopsies when there are signs or symptoms that something is wrong with blood cell production.
