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.
