connection devicedouble-ring retractorsurgical device


The invention falls under the surgical instruments category, in particular with those are used to retract and spread biological tissues in order to facilitate the vision of the intervention site and facilitate access to the operating field. In particular, the present invention describes a device that allows to join a retractor of the edges of a surgical wound with a valve that retracts and holds the internal viscera, thus allowing to maintain the advantages of a skin retractor (protection and homogeneous divarications of the edges of the wound ) but combining the advantages of a deep self-retaining retractor.

Technical features

Surgeons use a wide range of tissue-splitting instruments to make the area of the body undergoing surgery accessible and visible (so-called “retractors” or “retractors”). There are currently two main categories of these: superficial cutaneous, which keep the edges of an incision separate, and deep, which retain internal organs. In addition, there are manual retractors available on the market, which must be manually retained, and autostatic retractors, which can provide stable divarication without stable human intervention, but are impractical to handle and time-consuming to place, in addition to a special operating table. The patented invention (TRL3) combines the advantages of a superficial spreader, while also allowing deep spreading action, while maintaining the versatility, simplicity, and bulk of a wound spreader, and thus avoiding the use of cumbersome manual or self-locking deep spreading systems. In fact, the advantage is to evenly retract and protect the surgical incision with a wound spreader while at the same time being able to place autostatic valves for deep tissue and organ retraction allowing a precise and constant view of the surgical site.

Possible Applications

  • Surgery.


  • Quick to position even for emergency operations;
  • Space-saving and adaptable to the shape of the operating field;
  • Economical;
  •  Possibility of connecting several devices with several valves, in different positions and with different inclinations;
  •  Optimum positioning of devices and valves with respect to the operating field.
