Device for connecting conventional or laparoscopic instruments to a robot
View Patent ↗To connect conventional or laparoscopic instruments to a robot that can be used for medical applications, there can be a device that has a first and a second circular cylinder segment having a continuous center bore is connected with the angled first segment affixed to the free end of a robot arm. This connection can be by way of an articulated joint that can be rotated by 180°. On one end surface of the second segment, there can be a third segment in the form of a flange, having a bore that is coaxial with the continuous center bore in the second segment. There is also a rolling joint which can be used to allow the device to rotate. Around the bore of the flange, there can be supply technology and data technology connection elements and a locking mechanism for coupling end effectors on and off.

d) a flange forming a third segment, coupled to said circular cylindrical segment, said flange having a bore that is coaxial and continuous with said center bore in said circular cylindrical segment;
e) a plurality of data technology connection elements for electrically connecting the circular cylindrical segment with a medical instrument coupled to said circular cylindrical segment;
wherein said plurality of data technology connection elements are disposed around said bore of said flange;
wherein said flange is disposed on an end of said circular cylindrical segment;
f) said flange being provided with a locking mechanism for establishing a mechanical connection to medical instruments; and said flange being provided with the plurality of data technology connection elements; and
said locking mechanism is designed so that it can also serve as mechanical protection against incorrect assembly of said medical instruments to be connected; and
g) a rolling joint coupled to said circular cylindrical segment; and
wherein said rolling joint is for coupling said circular cylindrical segment to said flange, and wherein
said rolling joint is adapted so that a laparoscopic instrument can be inserted with its rod-shaped shaft through said rolling joint; and
h) said circular cylindrical segment ( 2 ) can be rotated by 180° around said articulating joint θ 1 , so that the laparoscopic instrument ( 4 ) can be connected or a non-laparoscopic instrument ( 6 ) can be connected.
2. The device as in claim 1 , wherein the circular cylindrical segment is adapted to connect a laparoscopic instrument at a proximal end of the circular cylindrical segment.
3. The device as in claim 1 , wherein the circular cylindrical segment is adapted to connect a non-laparoscopic instrument at a distal end of the circular cylindrical segment.
4. The device as in claim 1 , wherein the data technology connection elements are pins.
5. The device as in claim 1 , wherein said circular cylindrical segment ( 2 ) can be rotated by more than 180° around said articulating joint θ 1 , so that the laparoscopic instrument ( 4 ) can be connected or the non-laparoscopic instrument ( 6 ) can be connected.
6. A device for connecting instruments to an arm of a robot that can be used for medical applications comprising:
