Applicators for modular magnetic anastomosis device
The present disclosure provides description of applicators to implement modular magnetic anastomosis device. In one embodiment the delivery device is a laparoscopic instrument for MISS surgery, in another embodiment the delivery device is endoscopy or colonoscopy instrument for NOTES surgery.
1. A surgical system comprising:
(a) a modular magnetic anastomosis device configured to be introduced to an internal organ, wherein the modular magnetic anastomosis device is configured to form a circular anastomosis device and comprises two or more magnets enclosed in a flexible cartridge, and wherein the modular magnetic anastomosis device is ejectable; and
(b) an applicator for delivery of the modular magnetic anastomosis device to the internal organ during minimally invasive surgery, wherein the applicator comprises:
(1) a first elongated tube comprising a first hollow lumen connecting a first proximal end and a first distal end, wherein the first distal end comprises one or more teeth housings;
(2) a second elongated tube comprising a second hollow lumen connecting a second proximal end and a second distal end, wherein the second elongated tube is enveloped by the first elongated tube, and wherein the second distal end comprises one or more tooth-needles;
(3) a sealing system, wherein the sealing system comprises a valve which is configured to prevent air from escaping through the applicator when the applicator is placed into a peritoneal cavity and the peritoneal cavity is insufflated with air; and
(4) an actuation system connecting the first proximal end and the second proximal end, wherein the actuation system is configured to cause the ejection release of the modular magnetic anastomosis device when the modular magnetic anastomosis device is at least partially within the applicator and the actuation system is actuated,
wherein the one or more tooth-needles are configured to leave the one or more teeth housings to clutch and fasten the distal end of the first elongated tube to the internal organ.
2. The surgical system of claim 1 , wherein the second hollow lumen is configured to receive the modular magnetic anastomosis device.
3. The surgical system of claim 1 , wherein the actuation system is configured to cause a translational movement between the first elongated tube and the second elongated tube.
4. The surgical system of claim 1 , wherein the actuation system is ordered by a member selected from the group consisting of a button, a serrated roller, a handle actuating a radial toothed rack, and a handle actuating a longitudinal toothed rack.
5. The surgical system of claim 1 , wherein the second elongated tube is configured so that a sliding of the second elongated tube in the direction of the distal end causes the tooth-needle to leave the teeth housing.
6. The surgical system of claim 1 , wherein the one or more tooth-needles are configured to form a hook-or loop-shape after leaving the teeth housing.
7. The surgical system of claim 6 , wherein the one or more tooth-needles are configured to form a radially curved-shape.
8. The surgical system of claim 1 , wherein the applicator of the ejectable modular magnetic anastomosis device further comprises a laparoscopic instrument.
9. The surgical system of claim 1 , wherein the modular magnetic anastomosis device is configured to be delivered by the applicator through a natural orifice.
10. The surgical system of claim 1 , wherein the modular magnetic anastomosis device comprises an endoscopic instrument.
11. The surgical system of claim 1 , further comprising a piston formed from a rigid or flexible material.
12. The surgical system of claim 1 , wherein the one or more tooth-needles are retractable and extendable.
