Reciprocating surgical instrument

Номер: US20120029545A1
Принадлежит: MedicineLodge Inc

A surgical rasping system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping head which may be low profile and offer a flat cutting/rasping surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the rasping system to provide ablation or coagulation of soft tissues.

A suction retractor including an elongated tube that is operable to be inserted through a tubular retractor used in minimally invasive surgical procedures. One end of the tube is coupled to a handle having a chamber and the other end of the tube is coupled to a curved retractor portion, where the retractor portion allows the surgeon to hold back various anatomies during the surgical procedure. Thus, the suction retractor provides two functions that may otherwise require two different instruments. The retractor portion includes a series of parallel groves that allow liquids, such as blood, to flow along the retractor portion and into a suction port at the end of the tube. A suction device can be coupled to an outlet port in the handle that causes the blood and other surgical material to be sucked through the tube and out of the handle.

Devices and methods for vacuum-assisted removal of surgically contaminated gas from an insufflated body cavity, the contaminants comprising smoke, aerosols, vapor, mist and the like generated during surgical procedures in order to clear the surgeon's vision of the surgical site and prevent exposure of the surgical staff to the gas. One embodiment of the present invention comprises a series of flow restriction devices to enable stepping down of the flow rate generated by an external vacuum. This reduced flow rate allows safe yet rapid removal of the toxic and vision-obstructing surgical byproducts from the patient's body cavity. The initial flow restriction device may comprise a perforated trocar sleeve in fluid communication with the vacuum source that allows retention of the surgical instrument within the trocar sleeve's inner lumen with concurrent smoke removal. A series of additional flow restriction devices located downstream of the perforated sleeve's intake ports are employed to safely limit the flow rate to a manageable and known value.
