2. Digital Calipers:
   
   
   
   • Equipped with a digital display, these calipers are commonly used for quick and precise measurements. They are especially useful in medical device manufacturing and surgical planning.
   
   
   
   


3. Bone Calipers:
   
   
   
   • Specifically designed for orthopedic use, bone calipers are used to measure the dimensions of bones during surgeries or anatomical studies.
   
   
   
   


4. Cranial Calipers:
   
   
   
   • Used in neurology or pediatrics, cranial calipers measure head circumference or skull dimensions, aiding in the assessment of developmental milestones or conditions like hydrocephalus.
   
   
   
   


5. Dental Calipers:
   
   
   
   • Dental calipers are used by dentists and orthodontists to measure tooth size, arch width, or the thickness of dental materials.
   
   
   
   


6. Skinfold Calipers:
   
   
   
   • Often used in dermatology or fitness assessments, skinfold calipers measure subcutaneous fat thickness to estimate body fat percentage.
   
   
   
   


7. Ophthalmic Calipers:
   
   
   
   • In ophthalmology, these calipers are used for measuring the size of ocular structures, such as the cornea or intraocular lenses during eye surgeries.
   
   
   
   

Applications in Medicine

Medical calipers are versatile tools used in numerous medical disciplines for various purposes:

1. Orthopedics:
   
   
   
   • Bone calipers are used to measure fractures, bone lengths, and the dimensions of implants, ensuring precise alignment during surgical procedures.
   
   
   
   


2. Surgery:
   
   
   
   • In reconstructive or plastic surgery, calipers are employed to measure tissue thickness, distances, or implant sizes.
   
   
   
   


3. Dentistry and Orthodontics:
   
   
   
   • Dental calipers aid in creating precise dental prosthetics, braces, and aligners by measuring tooth and jaw dimensions.
   
   
   
   


4. Radiology:
   
   
   
   • Radiologists use calipers to measure anatomical structures on imaging studies such as X-rays, MRIs, or CT scans for diagnostic and procedural planning.
   
   
   
   


5. Pediatrics:
   
   
   
   • Cranial calipers measure head circumference to monitor the growth and development of infants and children.
   
   
   
   


6. Dermatology and Nutrition:
   
   
   
   • Skinfold calipers assess body composition and nutritional status by measuring subcutaneous fat.
   
   
   
   


7. Pathology:
   
   
   
   • Calipers are used in pathology labs to measure tissue samples and tumor sizes for diagnostic purposes.Advantages of Medical Calipers
