Multi lumen co-radial pneumatic connector
View Patent ↗A multi-lumen surgical utility connector is configured to receive two or more utilities from a surgical utility supplying device. The multi-lumen surgical utility connector may be connected to a utility port of the surgical utility supplying device which supplies two or more utilities. The multi-lumen surgical utility connector may include a Radio Frequency Identification (RFID) tag which identifies the type or model of multi-lumen surgical utility connector. The surgical utility supplying device may determine the type and parameters of utilities to be supplied through the multi-lumen surgical utility connector based on information read from the RFID tag.
1. A surgical utility connector configured to connect a vitrectomy probe to a surgical supplying device, the surgical utility connector comprising:
a first connecting region;
a first utility channel extending through a first step of the first connecting region;
a second utility channel extending through a second step of the first connecting region;
further comprising a third utility channel extending through a third step of the first connecting region;
a Radio-Frequency Identification (RFID) tag embedded in the surgical utility connector with information identifying the surgical utility connector;
wherein the first and second steps on the first connecting region are configured to mate with complementary receiving recesses on an opposing second connecting region to form a connection between the vitrectomy probe and the surgical supplying device;
wherein the second step protrudes further into the second connecting region than the first step when the first and second connecting regions are connected;
wherein the first and second connecting regions each convey a separate pneumatic air channel from the surgical supplying device to the vitrectomy probe.
2. The surgical utility connector of claim 1 ,
wherein the first connecting region is configured to interface with a utility port of the surgical supplying device; and
wherein the second connecting region is configured to interface with one or more utility tubes connecting to the vitrectomy probe.
3. The surgical utility connector of claim 1 , wherein the first step is a circular step and the second step is a circular step concentric with the first step.
4. The surgical utility connector of claim 1 , wherein the first step comprises a first seal disposed on a side wall of the first step and the second step comprises a second seal disposed on a side wall of the second step.
5. The surgical utility connector of claim 1 , wherein the second connecting region comprises a first tubing interface configured to connect a first utility tube to the first utility channel and a second tubing interface configured to connect a second utility tube to the second utility channel.
6. The surgical utility connector of claim 2 further comprising a ring-shape engagement rib protruding from an exterior surface of the surgical utility connector, wherein the ring-shape engagement rib is configured to be accommodated in a circular groove of the utility port of the surgical supplying device when the surgical utility connector is connected to the utility port.
7. The surgical utility connector of claim 2 further comprising an engagement nob protruding from an exterior surface of the surgical utility connector, wherein the engagement nob is configured to slide along and be accommodated in an engagement groove of the utility port of the surgical supplying device when the surgical utility connector is connected to the utility port.
8. The surgical utility connector of claim 1 , wherein the first and second steps protrude farther into the second connecting region than the third step.
