Computer assisted medical procedures use computer technology to assist with pre-surgical planning and guidance. This involves creating a virtual model of the patient using medical imaging like CT or MRI scans. The technology is used in various areas like neurosurgery where it increases precision, orthopedic surgery for joint replacements, and ENT surgery where it helps locate important anatomical structures. While it improves accuracy and reduces risks, computer assisted surgery is also very costly and its long term efficacy is still being established.

2. COMPUTER ASSISTED SURGERY
Represents a surgical concept and set
of methods, that use computer
technology for pre-surgical
planning, and for guiding or performing
surgical interventions.
What is Computer Assisted Surgery?

3. GENERAL PRINCIPLES
Creating a virtual image of the patient
The most important
component for CAS is the
development of an accurate
model of the patient. This
can be conducted through a
number of medical
imaging technologies
including CT, MRI, x-
rays, ultrasound plus many
more.

LOGOAPPLICATIONS

5. NEUROSURGERY
Telemanipulators
Allowed a greater development in
brain microsurgery ,increased
accuracy and precision of the
intervention.
• It also opened a new gate to
minimally invasive brain surgery.
• reducing the risk of post-surgical
morbidity by accidentally damaging
adjacent centers.

6. ORAL AND MAXILLOFACIAL SURGERY
In orthognathic surgery correction of
the anomalies of the jaws and skull
•It is also used in implantology where
the available bone can be seen and
the position, angulation and depth of
the implants can be simulated before
the surgery.
•During the operation surgeon is
guided visually and by sound alerts.
•
• IGI (Image Guided Implantology) is
one of the navigation systems which
uses this technology.

7. ENT SURGERY
•ENT commonly consists of navigating
preoperative image data such as CT or
cone beam
•CT to assist with locating or avoiding
anatomically important regions such as the
optical nerve or the opening to the frontal
sinuses
• For use in middle-ear surgery there has
been some application of robotic surgery
due to the requirement for high-precision
actions.

8. ROBOTIC SURGERY
•The application of robotic surgery
is widespread in
orthopedics, especially in routine
interventions, like total hip
replacement.
• It is also useful in pre-planning and
guiding the correct anatomical
position of displaced bone
fragments in fractures, allowing a
good fixation by osteosynthesis.
•Early CAOS systems include
the HipNav, OrthoPilot, and Praxim.

9. Visceral surgery
• Laparoscopy in abdominal and
gynecologic surgery is one of the
beneficiaries, allowing surgical robots
to perform routine operations, like
colecystectomies, or even
hysterectomies.
•In cardiac surgery, shared control
systems can perform mitral valve
replacement or ventricular pacing by
small thoracotomies.
•In urology, surgical robots contributed
in laparoscopic approaches for
pyeloplasty or nephrectomy or
prostatic interventions.

10. RADIOSURGERY
•Radiosurgery is also incorporating
advanced robotic systems.
•CyberKnife is such a system that has a
lightweight linear accelerator mounted on
the robotic arm.
•It is guided towards tumor processes,
using the skeletal structures as a
reference system (Stereotactic
Radiosurgery System).
•During the procedure, real time X-ray is
used to accurately position the device
before delivering radiation beam.

11. ADVANTAGES

12. 1. Preoperative diagnostic and a well-defined surgical planning
2.Surgeon can easily assess most of the surgical difficulties and risks
and have a clear idea about how to optimize the surgical approach and
decrease surgical morbidity.
3.The operation, the computer guidance improves the geometrical
accuracy of the surgical gestures and also reduce the redundancy of
the surgeon’s acts.
4.This significantly improves ergonomy in the operating theatre,
decreases the risk of surgical errors and reduces the operating time.

13. DISADVANTAGES
 New technology and its uses and efficacy have not yet
been well established.
 Another disadvantage of these systems is their cost.
With a price tag of a million dollars, their cost is nearly
prohibitive.
 One of the potential disadvantages identified is a lack of
compatible instruments and equipment. Lack of certain
instruments increases reliance on tableside assistants to
perform part of the surgery
