Abstract

A manifold (100) for collecting a tissue sample through a suction tube comprises a housing (102) comprising a sleeve (113) defining an opening (111), the sleeve (113) comprising an inlet fitting (112a) defining an inlet bore (114a) into the sleeve (113), and a tray (176). The tray (176) comprises a sealing member (154) configured to be positioned in sealing engagement with the opening (111) when the tray (176) is removably positioned within the sleeve (113), and a basket (180) comprising a proximal portion (206) coupled to the sealing member (154), opposing side portions (185) coupled to the proximal portion (206), a base portion (184) coupled to the opposing side portions (185), and a distal portion (190) coupled to the base portion (184) and the opposing side portions (185). The proximal portion (206), opposing side portions (185), the base portion (184), and the distal portion (190) collectively define a tissue collecting cavity (182) with the base portion (184) defining porous features (186) for collecting the tissue sample with the tissue collecting cavity (182), wherein the proximal portion (206) comprises a sealing edge (212). A distance between the opening (111) and the inlet bore (114a) of the housing (102) is less than a distance between the sealing edge (212) and the distal portion (190) of the tray (176).

Description

PRIORITY CLAIM AND RELATED APPLICATIONS This application claims priority to and all the benefits of United States Provisional Application No. 62/937,931, filed November 20, 2019, and United States Provisional Application No. 63/008,026, filed April 10, 2020, the entire contents of each is hereby incorporated by reference. This application is related to International Application No. PCT/US2019/032911, filed May 17, 2019, the entire contents of which is hereby incorporated by reference. TECHNICAL FIELD The present disclosure is generally directed to devices, systems, and methods for surgical procedures, and more specifically, but not exclusively, surgical procedures involving collecting a tissue sample under suction with a medical waste collection assembly. BACKGROUND Certain surgical procedures include the removal of a tissue sample for evaluation. For example, a polypectomy procedure involves removal of a polyp from surgical site within the patient, such as the colon or the endometrial tissue that lines the uterus. Often the polyp is aspirated with suction applied at surgical site with a medical waste collection assembly. Retrieving the polyp once collected in the suction path is an area of particular interest and development. Many known systems and methods are associated with several shortcomings, including increased time and inconvenience during the surgical procedure, potential exposure to hazardous medical waste, inability to collect multiple tissue samples, among others. Therefore, there is a need in the art for an improved manifold and methods for collecting the tissue sample with the manifold and the medical waste collection assembly.
