Abrading Device and Method for Creating Abrasions on a Membrane

摘要

An abrading device and method for irritating and blotting a membrane, particularly the pleural membrane. The method uses a device which is small enough to be inserted and withdrawn through a thoracoport. The device includes a proximal end configured to be gripped by a surgeon and a distal end configured to be inserted into the patient. A stainless steel shaft connects the distal and proximal ends of the abrading device. The distal end includes a series of nylon bristles. The bristles are attached to the device wire wrapped around the distal end of the device. The connecting shaft and wrapped wire are malleable. Once the device is inserted, the surgeon grips the proximal end and manipulates the device so that the series of nylon bristles abrades the walls of the pleural space. Once the abrading process is complete, the surgeon can easily withdraw the device back through the thoracoport.

主权项

1. A method for abrading a membrane located in a patient's body for a thoracic surgical action, said surgical action involving a pleural membrane, a parietal pleura, a pleural cavity, and an opening in said patient's body, comprising:
a. providing an abrading device, including,
i. a proximal end and a distal end,ii. a handle located on said proximal end,iii. a brush located on said distal end,iv. a shaft connecting said distal end and said proximal end,v. said brush having a plurality of bristles,vi. said distal end having a smooth, rounded tip; b. inserting said abrading device into said pleural cavity by passing said distal end through said opening; c. placing said brush against said parietal pleura in a position where,
i. said plurality of bristles rest against said parietal pleura,ii. said handle remains outside said patient's body; and d. abrading said parietal pleura of said pleural membrane so that said pleural membrane adheres to itself.
