Brachytherapy

 

 

Development of Proposal for improvement of Brachytherapy Procedure

 

Problem:Patient has to be shifted from transport bed to MR/CT table as well as radiation therapy bed. These movement increase risk of catheter movement.

A multifunctional transport bed

NEED Statement: A multifunctional transport bed with integrated stretcher and vacuum mattress is proposed as a solution.

Beneficiary: Patient, Assistant surgeon, Nurse

Description:

  • A vacuum mattress is used for immobilization of the patient in case of spine injury. Also ensures patient’s stabilization due to simple slats and strap.
  • A slightly bigger than normal size stretcher is constructed so that the patient can be positioned on the top of the operation/transport bed and then the whole construction would be moved slowly down to the operation table without shaking.
  • A vacuum mattress is added on the surface of the stretcher in order to keep the patient lying in stable position.

Result:

  • Movement of catheter caused by carrying patient and patient motion can be avoided.
  • Lesser chance of injury during transporting patient from one bed to another
  • Less workload on nurse and other medical staff at OR during surgery

Bed for brachytherapy

Urology

 

 

Brain Aneurysm

 

Problem:Surgeon has to stretch his hand for manipulating C-arm positions and movements.

An infrared LED system to maneuver C-arm position

NEED Statement: Develop an infrared LED system to maneuver C arm position automatically.

Beneficiary:Surgeon, Assistant surgeon

Description:

  • For controlling c-arm movements, during the time of image acquisition the relative position of the patient and the C-arm is measured and stored in position memory (in computer).
  • Special cameras are used to accurately track the positions of opto-electronically trackable marker shields containing infrared (IR) light-emitting diodes (LEDs) which are affixed to the C-arm.
  • The LEDs on shield are detected by the camera which monitors C-arm movement, position memory calculates the C-arm position in the coordinate space of tracking system.
  • The C-arm movement is then calibrated and registered with the stitched image

Result:

  • Allows surgeon to easily manipulate C-arm simply by using the scroll bars on a touch screen.
  • Possible to move the C-arm automatically in desired direction and make exposure with or without contrast agent

Automatic draining device

Unmet Clinical Need Evaluation


Automatic draining device

Problem: Waste fluid containers have to be drained manually which requires high workload for nurse and interrupts workflow of the surgeon as the containers need to be drained up to twelve times.

NEED Statement: Build an automated draining device to drain waste during surgery.

Beneficiary: Surgeon, Circulating Nurse

Description:

  • The Automatic draining device consists of a measuring unit, a pump, two waste fluid containers and a control unit.
  • As the first container fills up and reaches a certain level the pump switches to the other container and the first container is drained.
  • Hence one container is always being filled while the other container is drained.
  • A control unit, indicated by the touch screen, interacts with the measuring unit and the pump. This control unit also acts as a user interface where the values can be read out and the pressure can be set to a certain value.

Result:

  • Quantitative monitoring of blood volume
  • Automatic draining of waste fluid
  • Automatic changing of container
  • Continuous workflow without any break

Debris filter into a Lotus valve system

Unmet Clinical Need Evaluation


Problem: An imminent risk of releasing debris into the bloodstream which can potentially block blood flow resulting a cerebrovascular stroke.

NEED Statement: Introduce a model which fuses the debris filter into the Lotus valve system and eliminates the need for more incisions.

Beneficiary: Surgeon, Patient

Description:

  • The proposed catheter consists of three layers:
    • 1st layer − balloon catheter with stent and valve mounted
    • 2nd layer − debris filter
    • 3rd layer − filter cover
    • After the stent is approximately in the right position, the third layer starts to pull back. As the third layer uncovers the filter, the filter starts expanding and covers the whole diameter of the Aortic valve.
    • After the filter covers the whole diameter of the Aorta, the balloon starts expanding to place the valve in place. As the calcifications in the old valve are released, they get caught in the filter on their way.
    • The net then can be closed to hold the calcifications while pulling the catheter back out.

    Result:

    • Only one single filter is used which reduces complexity, expenditure time and cost
    • The filter is contained in the same catheter as the stent, resulting in no need to make more incisions and reducing time and complexity of the procedure

Automated gauze counting bin using photoelectric sensor

Unmet Clinical Need Evaluation


Automated gauze counting bin using photoelectric sensor

Problem: Human error of counting number of gauge pads being used during a surgery.

NEED Statement: Introduce a bin attached with photoelectric sensor for counting to reduce human error and workload of nurse

Beneficiary: Surgeon, Circulating nurse, Scrub nurse

Description:

  • The photoelectric sensor consists of a receiver and a transmitter
  • When a gauze pad is dropped inside the bin, the light from the transmitter to the receiver gets interrupted
  • This signal triggers the microcontroller to increment the count. The display unit attached to the microcontroller displays the value of number of gauze pads in the bin.
  • An option to reset via microcontroller

Result:

  • The photoelectric sensor will assist the nurse to count gauze pad in the bin
  • Less chance of human error as sensor will automatically detect the pads when it falls into the bin
  • Reduced workload for nurse

Dialysis: review and innovation

Unmet Clinical Need Evaluation


Dialysis: review and innovation

Problem: IV access is not always successful on the first attempt leading to cause complications due to extra attempts by surgeon and extra wounds on patient

NEED Statement: Introduce a system that can integrate ultrasonic imaging smoothly into vascular access procedure.

Beneficiary: Patient, Surgeon, Nurse

Description:

  • The system would be composed of: An attachment point for an ultrasound probe, linked to a system capable of performing Doppler ultrasonography to quickly locate and discriminate veins and arteries
  • A needle guide, adjustable in depth and approach angle, able to accommodate needle sizes and formats that are widely used in vascular access. Advancement of the needle would be performed manually
  • An algorithm or add-on to the ultrasound system software, which would compare the diameter of a previously saved target blood vessel to the current image, and inform the system operator if the system is no longer aligned to the center of the target blood vessel.

Result:

  • Useful for medical staff for basic access for vascular treatments
  • Reduce complication rate and average procedure time
  • Affordable as it does not contain complex components and ultrasound probes have already achieved widespread deployment in hospitals
  • Market demand is quite large as vascular access is needed in all major surgeries
