Module: Surgical Device Technology

Module Specifications.

Current Academic Year 2024 - 2025

All Module information is indicative, and this portal is an interim interface pending the full upgrade of Coursebuilder and subsequent integration to the new DCU Student Information System (DCU Key).

As such, this is a point in time view of data which will be refreshed periodically. Some fields/data may not yet be available pending the completion of the full Coursebuilder upgrade and integration project. We will post status updates as they become available. Thank you for your patience and understanding.

Description

To provide the students with an in-depth knowledge of the design and performance characteristics of various medical devices To expose students to real world problems associated with the use of a range of current surgical devices. To provide the students with a knowledge of a variety of surgical techniques, the range of surgical tools available and the design issues associated with those tools. To expose students to real world problems associated with the use of a range of current surgical devices. To engender in the students an awareness of the constraints within the environment of medical practitioners and the ethical implications of their work.

Learning Outcomes

1. Describe in detail a number of common surgical procedures using the appropriate medical terminology.
2. State (i) the Bioheat Equation, (ii) Heat diffusion/conduction equation, (iii) Surface heat convection equation, (iv) Heat radiation equation.
3. List factors affecting heat generation and tissue necrosis during various ablation techniques used in minimally invasive surgery, i.e., laser, radio frequency, microwave, ultrasound and chemical ablation. Describe briefly the theory behind each surgical technique.
4. Formulate analytical equations to estimate the heat generated in tissue by a variety of minimally invasive techniques and solve analytical problems.
5. Interpret empirical data relating to the design of stents and catheters and translate the data into numerical formulae to describe the behaviour of stents and catheters. Give examples of different stent designs and materials used for balloon catheters and stents.
6. Outline the key design and operational mechanisms of a range of open surgical devices, endoscopic and laparoscopic surgical devices. Explain the optimisation techniques used when designing laparoscopic instruments.
7. Subdivide the constituent parts of a robotics problem, and apply appropriate assumptions to determine the relationship between the end-effector of a robot and its global coordinates.
8. Understand and discuss the need for ethical standards and practice in the design and use of surgical devices.
9. Carry out a brief design synthesis of a surgical device and write a well organised project report

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 1
