Since the launch of the first Da Vinci System in 2.000, robotic surgery adoption has been less that it was expected. Many barriers have stopped hospitals to incorporate this modern technology. The following chapter describe briefly some actual ones.
1. Continued development of skills set for surgeons
Integrating surgical robotic technologies into practice is strongly influenced by adequate training of all team members and previous experience with robotic platforms.
2. Limited reimbursement
Reimbursement to hospitals and surgeons for surgical procedures can act as a significant booster for the uptake of products utilized during the surgery. If hospitals and surgeons receive the same reimbursement irrespective of the products that are used in the procedure, this will act as a hurdle for adoption.
3. Limitations with currently available robots
Limitations within general surgery include a large footprint (size) and lack of haptic feedback. Newer products expected to be launched are anticipated to address these limitations.
4. Lack of sufficient clinical trial studies
As with all new devices, more number of clinical studies is required to establish the clinical and cost-effectiveness of robotic surgical systems. Although the initial uptake of these systems in many regions have been positive, it is obvious that the full potential of these systems in a surgical setting has not been realized to its maximum specially in the cost-effectiveness.
In the following table we have a comparison resume between Open surgery, Minimally Invasive Surgery and Minimally Invasive Robotic Surgery.

North America represents the majority of the sales worldwide, 70%. Europe represents 15% of it and is expected to grow when North America is expected to maintain. This growth can be attributed two main drivers: 1) Increase in the adoption and number of indications, and 2) Increase in number of companies with their own products.
Source: GlobalData MediPoint Robotic Surgical Systems Global Analysis and Market Forecasts 2018Major manufacturers are increasing their R&D efforts within robotic surgical systems. Intuitive Surgical, with the Da Vinci System, is the market leader, and its global procedures increased by 32% from 2017 to 2018. The entrance of major manufacturers such as Johnson & Johnson and Medtronic are bolstering the medtech surgical robotics market.
Each company tries to highlight its own features like; medical indication, number of consumables, size (foot print), surgery versatility and required training will be some of key differentiation values between robots.
Recently, there have been major movements within the robotics surgical systems. Smaller manufacturers are focusing on technological advances within these systems, while major manufacturers are focusing on acquiring already established surgical systems.
Initial patents allowed Intuitive Surgical a colossal head start over their competition. Intuitive Surgical has filed and had published nearly four times as many patent families in the last five years than in the five years between 2004 and 2009. However, patents have a maximum term of 20 years, and the protection provided by Intuitive’ original patent portfolio has started to expire.

The application of machine learning to surgical robotic systems appears to be a frontier in the robotic surgical intellectual property space. It’s not an entirely open frontier. This predictive robotic surgery capability is clearly an area to watch for developments coming both from Verb Surgical (Google) and from the significant others.
Because of the multitude of technical areas involved in surgical robotics massive number of universities are working in the field. This is small representation among the total assignees universities. Highlight the strong showing by the University of Nebraska from the efforts of Drs. Dmitry Oleynikov and Shane Farritor who lead a robotics-focused effort there, and who also are co-founders of Virtual Incision.

Evolution is a continuous process and the surgical techniques are constantly being modified. The advent of Laparoscopy or Minimal Access Surgery was a boon to many patients giving them early recovery. Robotically assisted surgery was developed to overcome the pre existing limitations of Minimal Access Surgery i.e. 2D vision, dexterity, tremors, freedom and rotation of movements, surgical precision and accuracy and to enhance the capabilities of surgeons performing open surgery.
Future advances of robotic surgeries will be towards incorporation of all patient data like ultrasound, CT, MRI, etc. into robotic system to create a “virtual patient” and rehearse the surgery on virtual patient before actual surgery. Development of real time high speed data transfer technology will allow for Telerobotic Surgery.
Development of newer instruments and mass production of instruments may lower the cost of robotic procedures and will make it more affordable for a common man.

The Bitrack System
The bitrack System will be an alternative to the current laparoscopy surgical robot Da Vinci and will be an improvement on what is currently available in terms of efficiency.
It incorporates a flexible, modular and open robotic platform that improve the effectiveness of today’s robotic surgery and make it accessible to more hospitals around the world. It combines manual and robotic surgery, what is call hybrid minimally invasive surgery (HMIS).
The new robot has already been technically validated in experimental models, used by surgeons from the Mayo Clinic (United States) and the Barcelona university hospitals Clinic, Vall d’Hebron and Germans Trias. Between 2019 and 2021 Rob Surgical will build three new units to finalize the validation and industrialization process to expand the corporate and engineering team and will conduct the final safety and functionality trials.
Rob Surgical, the spin-off created by the Institute for Bioengineering of Catalonia (IBEC) and the Polytechnic University of Catalonia (UPC) in 2012, has closed a €5 million investment round with the Dutch holding Scranton Enterprises to fund the final phase of the new Bitrack System and launch the product onto the market.
