Ongoing Projects

In the last four years, BETiC team members have identified nearly 400 unmet clinical needs during visits to hospitals and discussions with clinicians. These were short-listed based on the size of the local market, innovation potential, manufacturability and availability of clinical guidance. Some of the short-listed problems were given to students and participants of innovation training workshops and are described in the next chapter. The projects are taken forward in BETiC IITB, COEP, and VNIT by full-time researchers, and are still under development or put on hold for any reason are briefly described here.

The devices are grouped into three categories as follows:

  • Diagnosis, screening & monitoring: Stroke Detection, Wireless ECG Patch, Pulse-Based Diagnostics, Pulmonary OAD Screener, Trachea Blockage Detector, Hemoglobin Quantifier.
  • Surgical instruments& tools: Modular Laparoscopy Heads, Endo Retractor, Surgery Forceps, Skin Gun.
  • Prostheses, orthoses &implants: Smart Acupressure Glove, Dialysis Cuff and Suture Anchor.

 

1.  Endoscope Insertion and Fixation

Back pain is the 2nd most common complaint in the country. Every person suffers from back pain at least once in his lifetime. Medicines have limited or no roles in treating back pain and medicines have a lot of side effects on the heart, Kidney and entire body.

Spine surgery is one of the solutions. However, Open spine surgery is risky and complications are high. Hence endoscopic spine surgery is one of the best options. It is very safe and can be done under local anesthesia. The patient can be discharged on the same day. However endoscopic spine surgery has a high learning curve. Hence many orthopedic surgeons, spine surgeons, neurosurgeons, and pain physicians tend to avoid this procedure.

Clinical Need Definition: Insertion of the guidewire is the first and most important step in performing this surgery. If the guidewire is inserted properly the surgery can be performed easily and it needs to hit the target in the first iteration only to avoid any trauma.

Demo of surgery

Device Development: Dr. Dinesh Kabre shared an initial design concept with the BETiC-COEP team to meet the clinical need. Dr. Sandeep Anasane, Swapnil Bukshete, Hemant Pawar, Dipak Chaudhary, and Abhijeet Bhagat had attended live surgery to understand the need and requirements. The developed instrument helps in the proper insertion of the guidewire in a standardized manner. Fixation of the endoscope by this instrument helps the surgeon to use both his hands freely; surgical precision increases. The same instrument can be used for giving root blocks and pain management in the lumbar region.

Pro-prototype Discussion with Dr. Dinesh Kabre and BETiC-COEP Team

This instrument will enable all Orthopedic, Spine, and Neurosurgeons to perform lumbar endoscopic spine surgery in a faster, precise and safer way. It will enable all Pain Physicians to give lumbar root blocks in an easy and safe way on Out-Patient Basis.

The functional prototype of the device has been developed under the Biomedical Engineering technology incubation center at the Department of Production Engineering and Industrial management, College of Engineering Pune.

 

2.  Monopolar Hook

The principle of electrosurgery revolves around the fact that human tissue introduced into an incomplete circuit will conduct current, there-fore closing the circuit and resulting heating of the tissue. There are two types of electrosurgeries monopolar and bipolar. Here we are targeting the device which will help in performing monopolar electrocautery surgery. Due to the traditional monopolar hook, there are chances of mechanical and thermal injuries during the operation, also efforts (Mechanical forces) required by surgeon to perform monopolar electrocautery are more.

Clinical need definition: these days clinician faces many problems In performing laparoscopic surgery due to unavailability of smart and effective instruments. After interacting and interviewing with Dr. Dasmit Singh, Pediatric laparoscopic Surgeon, he provides his clinical inputs to improve current instruments used in monopolar electrocautery. Device needs are listed below

  • The device should minimize mechanical and thermal injuries during surgery.
  • Mechanical forces required during operation should be reduced.
  • The current should stop flowing through the circuit at the instant, instrument leaves the tissue.
  • Flexibility in the shape and size of consumables.
  • The instrument should be low cost as compared to currently available methods.

Device development: Mr. Sandesh Patil is involved in the device from the inception of the problem statement, which is given by Dr. Dasmit Singh. During MEDIC 2018 which is held at IIT Bombay, he has developed a working proof of concept of the above-described problem. After discussing with the BETiC-COEP team some initial design sketches are made.

Currently, he is working on designing and a CAD model of the proposed solution after that will fabricate a new prototype. After fabricating the prototype, we will validate the same with Dr. Dasmit Singh for any further modifications if needed. This solution will surely solve clinical needs.
