Modular surgical tool

摘要

The present disclosure relates to a minimally invasive surgical procedure device including a set for forming a modular surgical tool, the set including a carrier shaft and a plurality of functional modules, in which the each functional module has means for rigid connection to the carrier shaft and/or to another functional module and has dimensions suitable for insertion into the body of a patient through a trocar, wherein the device is characterized in that: —each functional module has at least one degree of rotational or translational freedom and/or a functional end-piece such as a forceps, hook or a scalpel, —the carrier shaft and/or the functional modules include means for actuating the functional modules according to the respective degree of freedom thereof and/or the respective function thereof, and in that the device includes an electromechanical interface capable of controlling the actuating of the assembled functional modules forming the tool.

1. A minimally invasive surgical intervention device, comprising a set defining a modular surgical tool, the set comprising a carrier shaft and a plurality of functional modules, in which each of the functional modules has a connecting end fitted to the carrier shaft and to another functional module, and has appropriate dimensions for insertion into a body of a patient via a trocar, wherein:
each functional module has at least one of (i) a degree of freedom in rotation, (ii) a degree of freedom in translation, and (iii) a functional end-piece including one of: forceps, a hook, and a scalpel; at least one of: the carrier shaft and the functional modules are designed so as to actuate the functional modules according to at least one of: their degree of freedom and their respective function; the set further comprises a junction module configured to couple the carrier shaft to at least two of the functional modules in a branching manner, wherein the junction module has at least three connecting ends that are each fitted to at least one of the carrier shaft and the at least two functional modules; the set further comprises an electromechanical interface controlling the actuation of the installed functional modules which define the tool; and the connecting end of each of the functional modules is reversibly fitted to the carrier shaft.
