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; and
(b) an applicator for delivery of the modular magnetic anastomosis device to an organ, the applicator comprising:
(i) a first elongated tube comprising a hollow lumen connecting a proximal end and a distal end, wherein the distal end comprises elastically deformable arms that and form an elastically deformable pin configuration;
(ii) a second elongated tube that is enveloped by the first elongated tube and comprises a hollow lumen configured to receive the modular magnetic anastomosis device; and
(iii) a sealing system comprising a valve which is configured to prevent air from escaping through the applicator when the applicator is placed into the peritoneal cavity and a peritoneal cavity is insufflated with air;
wherein the second elongated tube is configured to slide relative to the first elongated tube and is positioned so that a sliding of the second elongated tube in the direction of the distal end causes the elastically deformable arms of the first elongated tube to radially expand thereby deforming an elastically deformable pin configuration so that the elastically deformable arms are pushed back towards an area surrounding the aperture and thereby fastening the applicator to a surgical area of interest;
wherein the modular magnetic anastomosis device is positioned within the second elongated tube so that when the applicator is fastened to the surgical area of interest and the elastically deformable arms are radially expanded, the modular magnetic anastomosis device passes through the second elongated tube to the organ.
2. The surgical system of claim 1 , wherein the applicator comprises a laparoscopic instrument.
3. The surgical system of claim 1 , wherein the second elongated tube is configured to slide relative to the first elongated tube when a button is pressed.
4. The surgical system of claim 1 , wherein the second elongated tube is configured to slide relative to the first elongated tube when a handle actuating a radial toothed rack is moved.
5. The surgical system of claim 1 , wherein the second elongated tube is configured to slide relative to the first elongated tube when a handle actuating a longitudinal toothed rack is moved.
6. The surgical system of claim 1 , wherein the modular magnetic anastomosis device is configured to be delivered through a natural orifice.
7. The surgical system of claim 1 , wherein the modular magnetic anastomosis device comprises an endoscopic instrument.
8. The surgical system of claim 1 , comprising a piston formed from a rigid material.
9. The surgical system of claim 1 , wherein the elastically deformable arms comprise resilient non-ferromagnetic metal.
10. The surgical system of claim 1 , wherein the elastically deformable arms have a conical shape.
