Apparatus and method for transvaginal surgery
View Patent ↗An access port for performing surgery transvaginally is provided. The access port includes an elongated flexible member having proximal and distal ends and a central portion therebetween, and a retention mechanism formed on the distal end of the elongated member. The retention mechanism includes a first configuration for inserting the distal end of the elongated member within an opening and a second configuration for selectively securing the elongated member within an opening. Also provided is a method of performing a transvaginal surgery. The method includes providing an access port including a retention mechanism configured to selectively retain the access port within the vagina of a patient, forming an incision in the wall of the vagina into the abdomen of the patient, inserting a distal end of the access port into the vagina and through the incision, and activating the retention mechanism to secure the distal end of the access port within the abdominal cavity of the patient.
1. An access port for use during transvaginal surgery comprising:
an elongated flexible member including:
a conical body portion forming a proximal-most end of the elongated flexible member;
a cylindrical distal portion extending distally from the conical body portion and defining at least one longitudinally extending lumen therein; and
an atraumatic distal tip portion having a conical shape and extending distally from the cylindrical distal portion, the atraumatic distal tip portion including at least one distal opening of the at least one lumen; and
a retention mechanism received about the elongated flexible member between the cylindrical distal portion and the atraumatic distal tip portion, the retention mechanism including a first configuration for inserting a distal end of the elongated flexible member within an opening and a second configuration for selectively securing the elongated flexible member within the opening.
2. The access port of claim 1 , wherein the cylindrical distal portion is configured to be selectively received through an incision in the posterior fornix of a vagina.
3. The access port of claim 1 , wherein the cylindrical distal portion is configured to be selectively received within an abdominal cavity of a patient.
4. The access port of claim 1 , wherein the cylindrical distal portion of the elongated flexible member includes multiple lumens extending therethrough.
5. The access port of claim 4 , wherein each of the multiple lumens is configured to receive a surgical instrument.
6. The access port of claim 4 , wherein each of the multiple lumens is configured to receive a surgical instrument in a sealing manner.
7. The access port of claim 1 , wherein the elongated flexible member is composed of foam.
8. The access port of claim 1 , wherein the elongated flexible member is composed of rubber.
9. The access port of claim 1 , wherein the retention mechanism includes a selectively inflatable member.
10. The access port of claim 1 , wherein at least one of a proximal end and a distal end of the conical body portion includes a rim.
11. The access port of claim 1 , including a rim formed between the cylindrical distal portion and the conical body portion.
12. The access port of claim 1 , wherein the atraumatic distal tip portion is frustoconical.
13. The access port of claim 12 , wherein the at least one distal opening is formed in a sidewall of the frustoconical atraumatic distal tip portion.
14. The access port of claim 1 , wherein the conical body portion, the cylindrical distal portion, and the atraumatic distal tip portion of the elongated flexible member are integrally formed.
