摘要:
Cathéter d'imagerie à ultrasons (50) constitué d'un corps (52) comprenant une région distale (54) et une région proximale (56). Ladite région distale (54) présente une surface en coupe transversale réduite par rapport à celle de la région proximale (56), et la région proximale comprend au moins deux lumens (64, 66) qui la traversent pour loger respectivement un fil de guidage mobile (68) et un élément de travail rotatif (72). On peut introduire le corps du cathéter (52) sur le fil de guidage mobile (68), le fil de guidage (68) traversant alors un lumen (64) situé dans la région distale et le lumen du fil de guidage situé dans la région proximale. Après avoir positionné le corps du cathéter (52), on peut rétracter le fil de guidage (68) de la région distale (54) et le faire pénétrer dans la région proximale (56), le lumen (58) se trouvant dans la région distale étant alors utilisable par l'élément de travail rotatif (72). Un dispositif de ce type permet de voir le cathéter par-dessus le fil tout en réduisant au minimum la longueur du cathéter (50) dans la région distale (54) qui reste disponible et utilisable pour placer l'élément de travail (72).
摘要:
A system and method for developing customized apparatus for use in one or more surgical procedures is disclosed. The system and method incorporates a patient's unique anatomical features or morphology, which may be derived from capturing MRI data or CT data, to fabricate at least one custom apparatus. According to a preferred embodiment, the customized apparatus comprises a plurality of complementary surfaces based on a plurality of data points from the MRI or CT data. Thus, each apparatus may be matched in duplicate and oriented around the patient's own anatomy, and may further provide any desired axial alignments or insertional trajectories. In an alternate embodiment, the apparatus may further be aligned and/or matched with at least one other apparatus used during the surgical procedure.

A trocar includes a plate member having a first surgical instrument port formed therein, a movable port that is provided separately from the plate member, and a cylinder part that is provided at the plate member and attached to an incised wound.
摘要:
A robotic surgical system is configured with rigid, curved cannulas that extend through the same opening into a patient's body. Surgical instruments with passively flexible shafts extend through the curved cannulas. The cannulas are oriented to direct the instruments towards a surgical site. Various port features that support the curved cannulas within the single opening are disclosed. Cannula support fixtures that support the cannulas during insertion into the single opening and mounting to robotic manipulators are disclosed. A teleoperation control system that moves the curved cannulas and their associated instruments in a manner that allows a surgeon to experience intuitive control is disclosed.

A trocar including a distal-end tube portion that is disposed inside the body and has a first inner hole through which a medical device can be inserted; a proximal-end tube portion that is disposed outside the body and is connected to the distal-end tube portion, the proximal-end tube portion having a second inner hole that communicates with the first inner hole and has an axis which can be disposed in a direction not parallel to an axis of the first inner hole; and a movement facilitating portion that is disposed on at least one of the inner surface of the first inner hole and the inner surface of the second inner hole to facilitate the movement of the medical device inside the inner hole.
摘要:
Provided are an overtube and an endoscopic surgical device that can remove foreign matter adhering to an observation window of an endoscope, with a simple operation, and can always guarantee an excellent field of view. A distal end of an endoscope insertion passage 306 through which the endoscope insertion part 102 of an overtube 300 is inserted is provided with a fluid supply and discharge port 500 for delivering cleaning water. In a case where an observation window of the endoscope insertion part 102 inserted through the endoscope insertion passage 306 is cleaned, an operator can set a distal end surface 114 at a predetermined positioning position using a positioning mechanism, without extracting the endoscope insertion part 102 from the endoscope insertion passage 306. Accordingly, a concave cleaning storage part 502 that communicates with the fluid supply and discharge port 500 on a distal end side of the distal end surface 114 of the endoscope insertion part 102 is formed inside the endoscope insertion passage 306 on the distal end side thereof. In this state, cleaning water is supplied from the fluid supply and discharge port 500, cleaning water is stored in the cleaning storage part 502, and foreign matter of the observation window is removed. Subsequently, the cleaning water stored in the cleaning storage part 502 is suctioned from the fluid supply and discharge port 500, and waterdrops are removed from the observation window.
