Definitions

  • the present disclosure relates to one or more embodiments of direct approach needle scopes and/ or endoscope apparatuses, to one or more embodiments of needle tip mechanisms for needle scope and/or endoscope apparatuses, and to one or more embodiments of methods and storage mediums for use with needle scopes and/or endoscope apparatuses (e.g ., direct approach scopes and/or endoscope apparatuses, scopes and/or endoscope apparatuses using one or more needle tip mechanisms, etc.).
  • Examples of needle scope applications include imaging, evaluating and characterizing/identifying biological objects or tissue, such as, but not limited to, for nasal applications (e.g., treating maxillary sinusitis, irrigating and suctioning the sinus, performing diagnostics (e.g., laparoscopy), etc.).
  • nasal applications e.g., treating maxillary sinusitis, irrigating and suctioning the sinus, performing diagnostics (e.g., laparoscopy), etc.

  • SEE Spectrally Encoded Endoscopy
  • An endoscope or some other medical probe has the ability to provide images from inside the subject.
  • the subject may be a human patient. Considering the risk to the subject caused by insertion of a foreign object, it is preferable that the probe be as small as possible. Additionally, the ability to image within small pathways such as vessels, ducts, needles, cuts, cracks etc., provides additional advantages to smaller probe sizes.
  • the ideal medical probe provides as much information with the least amount of disturbance.
  • Caldwell-Luc approach In procedures using a direct path to the maxillary sinus, physicians would sometimes go through the nasal cavity, and they would sometimes use the Caldwell-Luc approach. In the Caldwell-Luc approach, the physician gains access to the maxillary sinus through the patient’s mouth, above the teeth and below the lip. However, the Caldwell-Luc approach is not ideal because it involves additional risks of severing nerves, causing tooth damage, and creating healing complications. Additionally, the Caldwell-Luc approach has been associated with recurrent sinusitis and other issues.
  • each and every patient has unique sinus anatomy.
  • the sinuses are like fingerprints, with significant variation from one person to another. For example, 4% of the population does not have a frontal sinus and 14% of the population has frontal sinuses that are not fully formed. There are patients who may have had an orbital fracture and half their eye is sitting in the maxillary sinus. To avoid damaging the eye, physicians no longer blindly insert a needle into the maxillary sinus and inject or suction fluid.
  • ENTs generally treat maxillary sinusitis with sinus rinses, antibiotics, balloon dilation, and functional endoscopic sinus surgery (FESS).
  • the current treatment regimen is often ineffective and involves multiple visits to the ENT.
  • Diagnosis involves viewing in the nasal cavity with conventional rod-based endoscopes, without being able to see inside the sinuses.
  • Diagnosis often involves a CT scan of the patient as well.
  • a patient goes through multiple rounds of treatment for sinusitis by an ENT when they should be going to a headache specialist or other specialist, resulting in months of delay before effective treatment is obtained.
  • an ENT gets a new patient who he or she expects to have acute sinusitis, based on the patient’s symptoms and history.
  • the ENT puts a conventional endoscope into the nasal cavity to look for puss, but there is no puss present.
  • the ENT is not sure if the patient has an infection or not, as not all sinus infections result in puss within the nasal cavity. If this is the first time the patient has come in to this ENT, the ENT will typically put the patient on a course of 7, to, or 14 days of antibiotic, and tell the patient to come back.
  • the physician may try a different antibiotic.
  • the patient gets a CT scan. If there is nothing in the CT scan, then the ENT sends the patient to a headache specialist.
  • the headache specialist may be booking out 3 months. In this hypothetical, months have now elapsed from the time the patient first visited the ENT to the time the patient finally gets to see the headache specialist to diagnose and treat the issue(s). This has been several months of pain, days out of work, and multiple physician visits and associated costs.
  • Additional aspects of treatment(s) that are ineffective include: over-prescription of antibiotics and associated side effects on a patient and epidemiological effects on society; radiation exposure to a patient from CT in diagnosis; ballooning can cause recirculation; etc.
  • one or more needle tip mechanisms would be desirable to reduce or avoid the risk of the needle tip coming in contact with anatomy and causing harm as the ENT/physician inserts the guide in a nose of a patient.

  • a built-in scope may be used for numerous applications, including, but not limited to, treating sinusitis, viewing within the maxillary sinus, creating an artificial ostium (e.g., by needle puncture), etc.

Abstract

L'invention concerne des appareils et des systèmes d'imagerie à porte-aiguille ou endoscope utilisant une ou plusieurs caractéristiques d'approche directe ou d'imagerie directe et/ou un ou plusieurs mécanismes de pointe d'aiguille, ainsi que des procédés et des supports de stockage destinés à être utilisés avec ceux-ci. Les applications des porte-aiguilles comprennent l'imagerie, l'évaluation et la caractérisation/identification d'objets biologiques ou de tissu, tels que, mais sans y être limités, pour des applications nasales (par exemple, le traitement de la sinusite maxillaire, l'irrigation et l'aspiration des sinus, la réalisation de diagnostics (par exemple, une laparoscopie), etc.). Au moins un appareil ou système peut comprendre une aiguille ayant une ou plusieurs lumières ou espaces pour permettre à un imageur ou un dispositif d'imagerie et/ou à une zone de fluide d'y être disposée et de s'étendre à travers l'aiguille. Un ou plusieurs appareils, systèmes, procédés et supports de porte-aiguille d'approche directe, et/ou un ou plusieurs mécanismes de pointe d'aiguille, peuvent être utilisés avec un endoscope à codage spectral ou un autre dispositif d'imagerie.
