Attachments for use with a surgical access device

#The present disclosure is directed to various embodiments of attachments for use with surgical access devices. More particularly, the present disclosure includes attachments that are removably secured to a proximal portion of a surgical access device and allow instrumentation and/or a clinician's hand to be inserted therethrough.

#The present disclosure relates to a surgical access attachment for use with a surgical access device. The surgical access attachment includes a ring and an access portion assembly. The ring is configured to engage a proximal portion of a surgical access device. The access portion assembly includes at least one flexible tab having an engagement structure. The engagement structure is configured to selectively engage the ring. The access portion assembly is configured to retain a seal. The access portion assembly is configured to disengage from the ring in response to a predetermined amount of force exerted on one flexible tab of the at least one flexible tab.

#In disclosed embodiments, the access portion assembly is configured to disengage from the ring in response to a predetermined amount of proximally-directed force exerted on one flexible tab of the at least one flexible tab.

#Various embodiments of the present disclosure are disclosed herein with reference to the drawings, wherein:

#FIG. 1 is a perspective view of a surgical access attachment in accordance with embodiments of the present disclosure;

#FIG. 2 is an assembly view of the surgical access attachment of FIG. 1 which includes a ring and an access port assembly including a proximal seal retaining portion, a seal, and a distal seal retaining portion;

#Particular embodiments of the present disclosure will be described herein with reference to the accompanying figures. As shown in the figures and as described throughout the following description, and as is traditional when referring to relative positioning on an object, the term “proximal” refers to the portion of the device that is closer to the user and the term “distal” refers to the portion of the device that is farther from the user. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.

#As defined herein, a surgical site includes an incision in a patient or a natural orifice through which a surgical procedure may be performed.

#With initial reference to FIGS. 1 and 2, a surgical access attachment 100 is shown in accordance with embodiments of the present disclosure. Surgical access attachment 100 is configured for use with a surgical access device 300 (see FIGS. 7 and 8) for facilitating access through a layer of tissue “T” to a surgical site. More particularly, surgical access attachment 100, or portions thereof, are configured to be selectively removably attached to surgical access device 300, e.g., with the use of a single hand. That is, surgical access attachment 100, or portions thereof, are configured to engage surgical access device 300 in a simple, one-handed manner, and surgical access attachment 100, or portions thereof, are configured to disengage surgical access device 300 in a simple, one-handed manner.
