(google.co.uk)
  • 6. The biopsy needle guide as recited in claim 5 , wherein said spring means includes a distal portion that is adapted to mate with a third engagement feature arranged along a longitudinal front face of said ultrasound transducer and to be maintained in place thereby. (google.co.uk)
  • A lung biopsy can be performed percutaneously (through the skin, typically guided by a CT Scan), via bronchoscopy with ultrasound guidance, or by surgery, either open or by video-assisted thoracoscopic surgery (VATS). (wikipedia.org)
  • Ultrasound imaging is useful as the first-line, non-invasive investigation in determining the size, texture, position, and vascularity of a nodule, accessing lymph nodes metastasis in the neck, and for guiding fine needle aspiration cytology (FNAC) or biopsy. (wikipedia.org)
  • Ultrasound is also frequently used to guide FNA or core needle biopsy. (wikipedia.org)
  • cannula
  • The distal portion of the inner cannula is partially cut away to provide an insert recess which supports a semi-circular insert of hemostatic collagen which remains at the site upon removal of the needle to minimize hemorrhagic complications by promoting blood clotting. (google.com.au)
  • The insert and the distal portion of the inner cannula have radially outer surfaces of corresponding radius whereby the distal portion of the inner cannula and the insert supported thereon are received within the distal end of the outer cannula prior to use of the needle. (google.com.au)
  • Upon rotation of the inner tube with respect to the outer cannula, the coil will decrease in diameter to either sever or hold the biopsy piece within the outer needle. (google.com)
  • lesions
  • A 2003 Cochrane review found screening by breast self-examination is not associated with lower death rates among women who report performing breast self-examination and does, like other breast cancer screening methods, increase harms, in terms of increased numbers of benign lesions identified and an increased number of biopsies performed. (wikipedia.org)
  • Lymph Nodes
  • Patients with melanoma in situ, T1a melanoma or T1b melanoma ≤ 0.5mm have a low risk of cancer spreading to lymph nodes and high 5-year survival rates, so this kind of biopsy is unnecessary. (wikipedia.org)
  • apparatus
  • The needle apparatus comprises an elongate assembly of paired sleeves with an open notch in the wall of the outer sleeve for engaging a tissue volume in the bore of that sleeve. (google.com)
  • The apparatus is a biopsy needle comprised of a shaft, a tip which is flared in dimension with respect to the diameter of the shaft, and a longitudinal bevel which imposed on the tip. (google.com)
  • surgically
  • Abnormal findings on screening are further investigated by surgically removing a piece of the suspicious lumps (biopsy) to examine them under the microscope. (wikipedia.org)
  • An open biopsy consists of surgically removing all or part of a node. (wikipedia.org)
  • unnecessary
  • A muscle biopsy (immunohistochemistry or immunoblotting) or genetic test (blood test) confirms the absence of dystrophin, although improvements in genetic testing often make this unnecessary. (wikipedia.org)
  • confirms
  • Biopsy usually confirms the growth to be an adenoma, but, sometimes, excision at surgery is required, especially when the cells found at biopsy are of the follicular type. (wikipedia.org)
  • suspicious
  • A lung biopsy is performed when a lung lesion is suspicious for lung cancer, or when cancer cannot be distinguished from another disease, such as aspergillosis. (wikipedia.org)
  • guide
  • A new type of blood test in the U.S. is starting to transform cancer treatment, sparing some patients the surgical and needle biopsies long needed to guide their care. (medicalxpress.com)
  • The biopsy needle guide is arranged in two sections, an inner attachment block and an outer attachment block. (google.co.uk)
  • The outer attachment block includes a biopsy needle guide through hole and a second engagement structure. (google.co.uk)
  • 3. A biopsy needle guide as recited in claim 2 , wherein said first engagement means includes a ridge that extends from an outer surface of said inner attachment block and includes plural indents on opposed surfaces thereof. (google.co.uk)
  • 4. A biopsy needle guide as recited in claim 3 , wherein said second engagement means includes a pair of walls that are adapted to sandwich said ridge upon engagement of said first engagement means and said second engagement means, one said wall including a lip adapted to engage at least one of said plural indents. (google.co.uk)
  • lesion
  • Thus, a biopsy is rarely called for, especially if the lesion is homogeneous and smaller than 3 centimeters. (wikipedia.org)
  • paralysis
  • Additionally, there is a moderate risk of nerve injury, localized paralysis, or numbness when the biopsy is performed on a lymph node close to nerves. (wikipedia.org)
  • attachment
  • an outer attachment block including (i) means for guiding a biopsy needle tip into an imaging region of said emission face, (ii) second engagement means for releasably mating with said first engagement means, and (iii) coupling means for selectively fixing said first engagement means to said second engagement means upon engagement therebetween so as to fix said outer attachment block to said inner attachment block. (google.co.uk)
  • sharp
  • All needles are engineered for exceptional performance, featuring ultra-sharp tips and polished surfaces for smooth entry and exit. (bio-medicine.org)
  • inner
  • A stop engagement is provided between the second end of the pin and the second hub and is configured to prevent disengagement of the outer and inner needles and to maintain a specific physical relationship between the hubs. (google.com)
  • site
  • The skin over the biopsy site is cleansed, and a local anesthetic is injected (occasionally, a general anesthetic is given). (wikipedia.org)
  • Medical
  • Two very important innovations in the field of medical technology have influenced the field of tissue biopsy in the last five years. (google.com)
