Description
- This application is a Continuation application of U.S. patent application Ser. No. 12/706,029, filed on Feb. 16, 2010, which claims the benefit of, and priority to, U.S. Provisional Patent Application Ser. No. 61/162,358, filed on Mar. 23, 2009, now expired, the entire contents of each being incorporated by reference herein.
- 1. Technical Field
- The present disclosure relates to a surgical access device that is removably insertable into a patient's tissue. More specifically, the present disclosure relates to a surgical access device including a seal assembly adapted to accommodate the insertion of surgical instrumentation and/or surgical filaments, while substantially limiting the communication of fluids therethrough.
- 2. Background of the Related Art
- Many surgical procedures are performed through access devices, e.g., trocar and cannula assemblies. These devices incorporate narrow tubes or cannula percutaneously inserted into a patient's body, through which one or more surgical objects may be introduced to access a surgical worksite. Generally, such procedures are referred to as “endoscopic,” unless the procedure is related to the examination/treatment of a joint, in which case the procedure is referred to as “arthroscopic”, or to the examination/treatment of a patient's abdomen, in which case the procedure is referred to as “laparoscopic.”
- During these procedures, surgical filaments are often used to repair openings in skin, internal organs, blood vessels, and the like, as in the case of meniscal repair, and to join various tissues together, as in the reattachment of ligaments or tendons to bone. Additionally, a fluid, such as saline or an insufflation gas, e.g., carbon dioxide, is often introduced into the surgical worksite to increase visibility or access to tissue that is the subject of the procedure. Accordingly, the establishment and maintenance of a substantially fluid-tight seal is desirably to curtail the escape of such fluids and thereby preserve the integrity of the surgical worksite. To this end, surgical access devices generally incorporate a seal through which the surgical object and/or surgical filaments are inserted.
- While many varieties of seals are known in the art, there exists a continuing need for a seal that can accommodate a variety of differently-sized surgical objects and/or surgical filaments while substantially limiting the escape of fluids.
- Accordingly, the present disclosure is directed to a surgical access device for use during a surgical procedure. The surgical access device includes a housing, an access member extending distally from the housing and being dimensioned for positioning within tissue, and defining a longitudinal axis; and a seal assembly disposed within the housing. The seal assembly includes first and second seal components respectively having first and second seal members. Each of the first and second seal members defines a passage for passage of a surgical object in substantial sealed relation therewith. The first and second seal components are capable of relative rotation about the longitudinal axis between a first position, in which passages of the first and second seal members are in substantial alignment, and a second position where the passages of the first and second seal members are out of alignment to inhibit the communication of fluid through the seal assembly. At least one of the first and second seal components may be at least partially receivable within the other of the first and second seal components. The seal members may be configured as multi-slit valves. The first seal component may include a first base member and a first cap extending proximally therefrom, and the second seal component may include a second base member and a second cap extending proximally therefrom. The first cap may define a transverse dimension that is smaller than a transverse dimension of the first base member, and the second cap defines a transverse dimension that is smaller than a transverse dimension of the second base member. The first base member may define an internal cavity configured and dimensioned to receive the second cap.
- Detent means for releasably securing the first and second seal components in either of the first and second positions may be provided. The first seal component may include at least one detent configured and dimensioned for positioning within at least one recess on the second seal component. The seal assembly may include at least one bearing to facilitate relative rotation between the first and second seal components.
- A method of performing a surgical procedure, includes the steps of:
- accessing a body cavity with a surgical access device, the access device including first and second seal components respectively having first and second seal members, each of the first and second seal members defining a passage for passage of a surgical object;
- positioning the first seal component and the second seal component at a first relative angular position whereby passages of the first and the second seal components are offset from each other to substantially prevent the passage of fluid;
- moving, e.g., by rotating, the first seal component and the second seal component to a second relative angular position whereby passages of the first and the second seal components are in general alignment;
- subsequent to the step of moving, introducing a surgical objects into the surgical worksite through the surgical access device to carry out the surgical procedure.
- In another aspect of the present disclosure, a seal assembly adapted for use with a surgical access device is disclosed. The seal assembly includes first and second seal components respectively having first and second seal members. The first and second seal components are capable of relative rotation such that the seal assembly is movable from a first position, in which passages defined by the first and second seal members are in substantial alignment, to a second position, in which the passages defined by the first and second seal members are out of alignment to inhibit communication of fluid through the seal assembly.
