LapC-FORCE: Surgical device to improve laparotomy closure for incisional hernia prevention

Posted by Universitat de LleidaResponsive · Patents for licensing · Spain

Summary of the technology

A multidisciplinary team involving doctors and engineers developed a medical device to cover the surgeons’ need at the moment of closing a laparotomy. With real-time information on force and distance, surgeons may decide the most appropriate closure technique and materials to be used for each single patient for reducing the laparotomy’s closing force and therefore, to prevent incisional hernias. We currently have a prototype medical device that measures the closing force between edges in a laparotomy. It was designed and tested in non-regulatory preclinical trials using pigs.
We are looking for an industrial partner with expertise in the sector of medical devices willing to add in its product pipeline a new surgery device to assist surgeons during a laparotomy. The type of partner sought is mainly for regulatory development and commercialization under a technology license agreement.

Description of the technology

The risk of developing an incisional hernia (IH) after a laparotomy is between 9-20%, and 90% occur within 3 years after surgery. Just in USA, more than 200,000 IH per year are treated, with estimated costs of 2,500 M$. Although these complications are mainly related with intrinsic factors of patients, there are also surgical factors such as the closing tensiometry, the type of suture material and/or the surgical technique involved. The surgical technique and materials used to close this type of incision in the abdominal wall are selected on the basis of the surgeon’s experience and therefore, it is mainly empirical.

To adress this issue, we developed a medical device that measures the closing force between edges in a laparotomy. It was designed and tested in non-regulatory preclinical trials using pigs of different weights as a simulation of different types of patients to be treated in a surgery room.

Innovations and advantages

  • Prototype of medical device of reduced dimensions to be used in surgical rooms
  • Proven use in preclinical models (pigs)
  • Force and distance measurements are made and registered in a sensor simultaneously
  • High accuracy determinations: for the force (±0.2 N) and the distance (±1 mm)
  • Several instruments can be coupled to obtain measures at the same time at different zones in a laparotomy

Applications

A clear commercial application is identified for laparotomy (large incision through the abdominal wall to gain access into the abdominal cavity). Nevertheless, this technology - with special adaptations or innovations - could be potentially useful for other major surgery interventions in the field of –otomies, where measuring forces and distances between edges within a surgical incision is required.
