Definitions
- the invention relates to robotized training modules of elongated flexible medical organs.
- the invention relates to the insertion of a guide wire, a catheter guide (known under the term "guidewire” in English) and the catheter itself, in particular for treating cardiovascular pathologies, in an artery of a patient.
- a catheter guide is an elongated, soft, generally small, non-hollow medical organ on which a catheter is threaded.
- a catheter is an elongated flexible medical organ of larger diameter, generally hollow, threadable on the guide.
- the catheter may have a medical function, generally at its end inserted into the patient, such as a tool or a particular shape.
- the invention applies to any medical device flexible enough to be movable in a physiological channel of a human patient, and sufficiently elongated so that its end can be moved from outside the patient.
- the reliability of the training module is based, inter alia, on the fact that the catheter is in a sterile state when it is introduced into the patient.
- the robotic training module which is expensive, is intended to be used to operate a large number of patients and to be stored between two uses.
- the robotic drive module may come into contact with microorganisms or dust. Therefore, to avoid dirtying the catheter and / or the robotic module, a sterile, disposable protective envelope is placed on the robotic drive module before each operation.
- Document WO 2015/189529 notably describes such a protective envelope.
- the envelope covers, at least partially, the robotic drive module and helps to form a sterile barrier between the drive module and the catheter. Movement is transmitted from the robotic module to the catheter, or catheter guide, through the envelope.
- the protective envelope is alone in direct contact with the catheter and the guide during the placement procedure in the patient. Therefore, it usually carries a guiding track of the guide or catheter.
- the guideway of the catheter provides a surface carrying for example the catheter or the guide of the catheter and for moving it along the track which is rectilinear so as to define a longitudinal axis.
- This track forms a tube whose diameter is greater than that of the elongated flexible medical organ.
- the tube is formed by two half-tubes that can be detached from one another and whose separation surface is located in a substantially horizontal plane passing through the axis of the tube so as to deposit or remove the catheter or the guide in or from the guide track.
- the tube When the tube is open, it is necessary for the surgeon to be able to deposit the catheter or guide correctly, while the diameter of the tube is smaller than a dimension of a surgeon's finger.
- the tube When the tube is closed, it is necessary that the catheter or guide be properly held in the tube. Indeed, if the tube has too large a diameter, the catheter or the guide may not be kept rectilinear when moving. If the tube is too small in diameter, the catheter or guide will rub excessively against its walls as it may deteriorate.
- An object of the invention is therefore to provide a more reliable protective envelope that allows precise positioning of the elongated flexible medical device which may in particular be a catheter or a guide.
- the invention provides a protective envelope for a robotic module for driving an elongate flexible medical device, intended to form a barrier between the robotic drive module and the elongated flexible medical device, characterized in that it comprises: fastening means to the robotic module, and
- the main portion comprises a longitudinal groove for accommodating the elongate flexible medical organ extending along the longitudinal axis and dug into the free surface having the concave shape.
- the concave shape of the free surface of the main portion allows a user, including a surgeon, to manually position the elongated flexible medical organ in the longitudinal groove before beginning the insertion operation in the patient's body.
- the groove accommodates the elongated flexible medical organ and the concave shape allows the user to lock the flexible medical organ elongated in the groove by the simple pressure of a finger.
- the establishment of the elongated flexible medical organ in the envelope is therefore simpler and more reliable.
- the longitudinal groove has a free surface whose cross section has a shape of "V” or "U".
- Such a shape is adapted to accommodate the elongated flexible medical organ. It is also specified that it is the groove, which has dimensions adapted to position the elongated flexible medical organ, which has a free surface whose cross section has a shape of "V" or "U” and not the surface free of the guide track as a whole.
- the longitudinal groove belongs to a plane of symmetry of the free surface having the concave shape.
- the envelope is therefore simple to manufacture, in particular by injection molding.
- the free surface having the concave shape has a radius of curvature of between 0.5 and 3 cm, or a radius of curvature of between 1 and 2 cm.
- Such a range of curvature radii generally follows the shape of the lower surface of the end of a human index.
- the manual placement of the catheter in the longitudinal groove is therefore all the more simple.
- the main portion comprises at least one transverse groove, extending perpendicularly to the longitudinal axis, hollowed in the free surface having a concave shape.
- the transverse groove is able to accommodate complementary positioning means of the elongated flexible medical device, which improves the reliability of the positioning of the elongated flexible medical device.
- the guide track comprises a second portion which comprises at least one support member of the elongated flexible medical member, a free surface of which comprises two branches which each have a convex shape and which delimit a groove adapted to receive the organ flexible medical elongated.
- the free surface of the support member of the elongated flexible medical organ is offset, in a direction perpendicular to the longitudinal axis of the guide track, relative to the free surface having the concave shape.
- the envelope comprises at least two transverse grooves, the support member of the elongated flexible medical member is disposed along the longitudinal axis, between the two transverse grooves.
- the catheter is further stretched for the same overall length of the guide track.
- the reliability of the positioning of the catheter is therefore improved.
- the envelope comprises a removable cover adapted to occupy an open position in which the cover releases access to the guide track and a closed position in which the cover encloses, at least partially, the guide track.
- the cover thus protects the guide track and the catheter when present.
- the cover and the guide track comprise complementary guide members of the elongated flexible medical device.
- the complementary guide members of the elongated flexible medical organ cooperate to grip the catheter on all sides and thus position it more precisely.
- the guide member carried by the cover has a free surface which has a cross section in the shape of "W".
- This free surface encloses the elongated flexible medical organ to position it with even more precision.
- the guide member is configured to be positioned in the transverse groove when the lid is in the closed position.
- the envelope comprises lid locking means in the closed position, electrically controlled.
- the cover locking means in the closed position are connected to a presence sensor adapted to lock the lid in the closed position when the presence sensor detects a presence near the protective envelope.
- the envelope comprises a pair of drive members of the elongated flexible medical device, the drive members are opposed in pairs on either side of the longitudinal axis of the guide track.
- an assembly comprising a robotic module for driving an elongate flexible medical device and a protective envelope, as described above, the envelope being fixed to the robotic drive module so as to forming a barrier separating a space comprising the robotic module from a space comprising the elongate flexible medical organ.
