Embodiment Construction

[0028] The present invention provides a variety of liquid ejection instruments for use in a variety of applications, many of which are well suited for use in a variety of surgical procedures. Certain embodiments of the present invention provide liquid ejection instruments that can be configured in various ways for use in various surgical fields. Certain surgical instruments according to the present invention are configured as surgical grips having a proximal end or handle with a gripping region that is shaped and configured to allow the operator to use Comfortable to hold in hand. The instrument may also have a distal end comprising at least one nozzle for forming a liquid jet. The distal end of certain embodiments of the surgical instruments of the present invention can be used to perform surgical procedures on a patient. Although the liquid ejection instruments described herein have a grip configuration, it should be understood that the present invention is not strictly li...

Abstract

The invention provides a variety of surgical instruments for forming a liquid jet, which are useful for performing a wide variety of surgical procedures. In some embodiments, the invention provides surgical liquid jet instruments having a pressure tube and an evacuation tube, where the pressure tube includes at least one nozzle for forming a liquid jet and where the evacuation tube includes a jet-receiving opening for receiving the liquid jet when the instrument is in operation. In some embodiments, the distal ends of both the pressure and evacuation tubes have a first configuration in a non- relaxed state and a second configuration in a more relaxed state. In some embodiments, a straightener is constructed to selectively control the configuration of the distal ends of both the pressure and evacuation tubes. The invention also provides surgical methods utilizing the inventive surgical liquid jet instruments for cutting or ablating a selected tissue within portions of a patient's spine, such as within the intervertebral disc.

Description

technical field [0001] The present invention generally relates to surgical instruments for forming liquid jets, and methods of using the same in surgical procedures. Background technique [0002] It has become a trend in recent years to access surgical sites via small holes through the skin or through body orifices, whereby many surgical procedures are performed using less invasive techniques. These techniques are called "minimally invasive surgery." Commonly used minimally invasive surgical techniques include endoscopic, laparoscopic, and arthroscopic surgery. Minimally invasive surgery is often preferred over open surgery for many applications because it involves less trauma to the patient during the surgical procedure, and in many cases has fewer potential complications and shortens recovery time Surgery. [0003] A large number of instruments have been developed and used in minimally invasive surgery. Frequently used instruments include blade and scalpel instruments,...
