Definitions

  • the present disclosure relates to a needle guide apparatus.
  • the present needle guide apparatus may be used, for example, in ultrasound guided procedures.
  • Anesthesiologists may perform nerve block or vascular access procedures. Radiologists may perform diverse procedures such as vascular access, biopsy or intra-articular injections. Some Rheumatologists also perform musculoskeletal injection involving joints, bursi and soft tissue.
  • Nerve block is a commonly performed procedure among medical professionals
  • an ultrasound probe initially scans a target area of a subject.
  • a needle is then positioned relative to the base of the ultrasound probe such that the long- axis of the needle will be visualized within the scanning plane of the ultrasound probe when the needle is inserted into the patient.
  • anaesthetic is injected onto or near the nerve to create the nerve block.
  • Vascular access is practiced by anesthesiologist, critical care specialists and radiologists. It uses the similar principles. It is often advisable to do the vascular access 'in-plane' to visualize the vessel and needle entry into it.
  • Biopsies taken by radiologists or other specialists also use similar 'in-plane' or 'out of plane' approaches to access the target.
  • an ultrasound probe initially scans a target area of a subject.
  • a needle is then positioned relative to the base of the ultrasound probe such that the short-axis of the needle will be visualized within the scanning plane of the ultrasound probe when the needle is inserted into the patient.
  • anaesthetic is injected onto or near the nerve to create the nerve block.
  • the target and the needle tip are often difficult to locate making it difficult to contact the nerve with the needle tip. Targeting is often confirmed by secondary indicators such as nerve stimulation, local anaesthetic effect or aspiration of blood.
  • the needle tip In the 'in-plane' approach, the needle tip must be visualized in the scanning plane from the time the needle is inserted into the patient to the time the needle tip contacts the target. Should the angle of needle insertion be incorrect or misaligned with the scanning plane, a needle operator runs the risk of the needle tip falling outside the scanning plane and therefore losing ultrasound-generated visualization of the needle tip as it approaches the targeted area. Should such visualization of the needle tip be lost, the needle tip may not reach the target or worse, inflict unintended damage to the patient. In addition, it may take the needle operator multiple attempts to properly align the needle with the scanning plane thereby inflicting puncture wounds on a subject. Such problems lead to procedural delays and unnecessary trauma to the patient, and increase the risk of further medical complications. Similar requirements and potential sources of error and delay also exist for Out-of-plane' approaches to creating nerve block.
