Study Notes
Diagnostic Devices and the Digestive and Sensory Organs
- Most figures/tables/texts in this lecture are from the textbook “Introduction to Biomedical Engineering Technology by Laurence Street 2016”
- The lecture is about medical engineering focusing on the digestive system and sensory organs.
Anatomical Terms
- Proximal: Nearer to the point of attachment to the body.
- Distal: Further away from the point of attachment of the body.
Types of Endoscopes
- Rigid Endoscopes:
- Components: Made with a stainless-steel tube, fiber-optics, lenses, and open passages.
- Functional Components:
- Distal End Section: Contains an objective lens for capturing and focusing the image.
- Telescope Section: Has lenses separated by spacers.
- Open Passage Section: Used for irrigation, suction, and insertion of tools for surgery or biopsies.
- Flexible Endoscopes:
- Structural Components: Includes a light guide tube, bending section, and control body.
- Functionality and Distal End Anatomy: Illumination and visualization are achieved through fiber-optics, allowing for the transmission of light and image capture.
- Risks: Potential risks include bleeding, infection, and discomfort.
Types of Endoscopic Procedures
- Thoracoscopy: A minimally invasive procedure for examining the pleural and thoracic cavities.
- Indications: For diagnosis or treatment of conditions like lung cancer or pleural effusion.
- Risks: Risks include bleeding, infection, or lung injury.
- Laparoscopy: A minimally invasive surgery using a thin, lighted tube inserted into the abdomen to examine abdominal or female pelvic organs.
- Indications: For diagnosis or treatment of conditions like endometriosis, appendicitis, or pelvic inflammatory disease.
- Risks: Risks include infection, bleeding, or injury to surrounding organs.
- Arthroscopy: An instrument used for inspecting, diagnosing, and treating joint issues through a minimally invasive procedure.
- Indications: Used for repairing torn meniscus, removing loose cartilage, or diagnosing joint pain.
- Risks: Risks include infection, bleeding, or injury to surrounding organs.
- Colposcopy: A diagnostic instrument used to magnify and examine the cervix, vagina, and vulva for signs of disease or abnormalities.
- Indications: Recommended after an abnormal Pap test result or to investigate symptoms like unusual bleeding.
