Abstract

Devices and methods for collecting tissue fragments of variable sizes from a surgical site are described herein. The devices can include at least two filters having a different pore size for the collection and sorting of tissue fragments by size.

Core Innovation

The disclosure describes a device for collecting tissue fragments of variable sizes for orthopedic surgical sites. The device includes a top housing and a bottom housing that assemble into a container, each having an inner surface and a universal adapter.

The device uses at least two slidably removable filters, where each filter comprises a filter material and has a different pore size, enabling collection of variable-size tissue fragments. The at least two filters are assembled in series onto a filter distractor, and the filter distractor comprises at least two ridges configured to hold the filters in place.

The filter distractor and the at least two filters are inserted into the top housing or the bottom housing, and the housings are assembled together into a container. Fluid flow through the series arrangement enables size-based sorting from larger pore sizes toward smaller pore sizes.

Claims Coverage

The independent claim requires a variable-size tissue fragment collection device with a top housing, a bottom housing, at least two slidably removable filters of different pore sizes assembled in series on a filter distractor with ridges, all contained within a container.

Top and bottom housings with universal adapters

A top housing comprising an inner surface and a first universal adapter, and a bottom housing comprising an inner surface and a second universal adapter, wherein the top housing and the bottom housing are assembled together into a container.

At least two slidably removable filters with different pore sizes

At least two slidably removable filters comprising a filter material and each having a different pore size.

Filter distractor with ridges to hold filters in place

A filter distractor comprising at least two ridges each configured to hold one of the at least two filters in place.

Filters assembled in series onto the filter distractor

The at least two filters are assembled in series onto the filter distractor.

Insert filters and distractor into housing container

The filter distractor and the at least two filters are inserted into the top housing or bottom housing.

Overall, the claim coverage centers on a series-connected, pore-size-differentiated filter set held by a ridge-based filter distractor and contained within a top-and-bottom housing container using universal adapters.
