Embodiment Construction

[0098] figure 1 Shown is a robotic arm 10 comprising at its free end a needle guiding device 20 according to a first embodiment intended to assist the operator in introducing a needle into a patient during a medical procedure until it is inserted into a target anatomical region. The robotic arm 10 preferably comprises a tool changer at its free end, which provides a contact surface between said free end and the guide means 20 .

[0099] Such as figure 2 and image 3 As shown, the guide device 20 comprises a tool holder 21 intended to be fixed to the robot arm 10 and a needle guide 22 cooperating with said tool holder 21 .

[0100] The tool holder 21 comprises a housing 210 extending longitudinally between two end openings respectively opened in a surface 211 called the "upper surface" and a surface 212 called the "lower surface" of the tool holder 21. . The housing 210 is bounded by an inner wall 213 between two end openings.

[0101] exist Figures 1 to 3 In the prefer...

Abstract

The present invention provides a needle guide device (20) and a robotic arm comprising the same. The needle guide device comprises a tool holder (21) intended to be fixed to an end of a medical auxiliary robotic arm (10), the tool holder (21) supporting a needle guide (22); the needle guide (22) comprises two jaws (30, 40) each having a groove (35, 45), the two grooves extend along a parallel longitudinal axis, and the jaws (30, 40) are supported by the tool holder. Thus, mobility of rotation of the jaws (30, 40) relative to each other is allowed between the following two positions: a guide position in which the grooves (35, 45) are adjacent and define a guide tube (23) for guiding the needle, and a disengaged position in which the grooves (35, 45) are moved away from each other and definea needle lateral disengaged zone.

Description

technical field [0001] The present invention relates to medical equipment and to the field of medical equipment mounted at the end of a medical assistance robotic arm. The present invention more particularly relates to a medical needle guide for attachment to a tool holder of a robotic arm. Background technique [0002] Surgical treatment using a surgical technique known as "minimally invasive surgery" enables the operator (usually a surgeon) to reach the patient's target anatomy by inserting long, thin instruments into short length incisions An area, for example of the order of one centimeter, occurs within a patient's body. [0003] In some procedural contexts, those instruments may be one or more needles or rigid cylindrical instruments (eg, antennae, electrodes, cannula) intended to be inserted into the patient to a depth to reach the target anatomical region. [0004] If the needles are inserted entirely manually by the operator, the outcome of the treatment depends l...
