Abstract
A medical instrument for shaving, collecting, and removing vertebral disc material from a vertebral disc space of a spine, has a shaft defining a proximal shaft end and a distal shaft end, and an auger at the distal shaft end. The auger has a plurality of helical cutting flutes configured to shave and collect vertebral disc material from the vertebral disc through rotation of the auger. Each helical cutting flute has a cutting apex that together define a cutting tip, and a radially inward helical slot that collectively define an internal cavity for collection of cut vertebral disc material. The plurality of cutting apexes converge at the cutting tip, defining a point. The medical instrument includes a connector to allow attachment of a handle. A notch in the proximal shaft end that receives a flange of the handle prevents rotation of the handle relative to the auger.
Description
- This U.S. non-provisional patent application claims the benefit of and/or priority under 35 U.S.C. §119(e) to U.S. provisional Pat. application serial number 63/314,017 filed Feb. 25, 2022 titled “Vertebral Disc Auger,” the entire contents of which is specifically incorporated herein by reference.
- The present invention relates to instruments for spine procedures and, more particularly, to instruments for removing vertebral disc material from a vertebral disc space of a spine.
- A large majority of people develop spine issues because of age, disease, trauma, acquired complication, and/or other reason. Some spine issues can be alleviated without surgery while other spine issues necessitate surgery. In some circumstances, it may be necessary to remove vertebral disc material from between adjacent vertebrae of the spine. Such a procedure is now routinely accomplished using minimally invasive surgery or micro invasive surgery (collectively, MIS). Both procedures reduce bodily trauma by utilizing surgical instruments that are introduced into the body via a small incision via a cannula and/or an endoscope (i.e. tube). The medical instrument is inserted into and through the tube and operated accordingly.
- Various forms of medical instruments are known to provide vertebral disc material collection and/or removal. Many, however, are not suitable for use in MIS. One form of suitable MIS medical instrument for removing vertebral disc material from the vertebral disc space of adjacent vertebrae of the spine is an auger. A vertebral disc material auger for MIS has a head designed for insertion into and through a tube for harvesting vertebral disc tissue. Current MIS augers for harvesting vertebral disc material from a vertebral disc space between adjacent vertebrae of a spine however, are deficient in various respects.
- It would therefore be advantageous to have an MIS medical instrument for harvesting vertebral disc material that overcomes the deficiencies of the prior art. It would therefore be further advantageous to have an MIS auger for harvesting vertebral disc material that reduces surgical complexity. It would furthermore be advantageous to have an auger for an MIS spine procedure that provides efficient collecting and removing of vertebral disc material.
- The present MIS medical instrument addresses the above and more.
- A medical instrument for removing vertebral disc material particularly, but not necessarily, during an MIS spine procedure, has a proximal end configured as or for attachment to a handle, a shaft extending from the proximal end, and a head formed as an auger at a distal end of the shaft, the auger having a plurality of cutting flutes configured to shave and collect vertebral disc material from a vertebral disc in a vertebral disc space of a spine through rotation of the auger.
- The cutting flutes spiral or twist along a longitudinal axis of the shaft. In one form, the auger has three spiral cutting flutes, each spiral cutting flute making a 120° rotation about the head along the longitudinal axis of the shaft from a tip. Other numbers of spiral cutting flutes as well as their amount of rotation about the head along the longitudinal axis of the shaft are contemplated and may be used. Each one of the plurality of spiral cutting flutes extends from an angled apex which together, form the tip at the distal end of the auger.
- A cavity is formed in the auger with each one of the plurality of spiral cutting flutes having a radially inward slot in communication with the cavity. Each slot extends along the longitudinal axis of the respective spiral cutting flute. The internal cavity of the auger and the slots of the spiral cutting flutes together define an area for collection of cut vertebral disc material.
- The proximal end may include a notch or other structure configured to receive a flange or other structure of a handle, or configured as a handle.
- The auger may extend from a neck at the distal end of the shaft with each one of the plurality of spiral cutting flutes having a proximal end that extends from the neck, each one of the proximal ends of the spiral cutting flutes having a surface sloped radially inward from the neck.
- Further aspects of the present invention will become apparent from consideration of the drawings and the following description of the invention. A person skilled in the art will realize that other forms of the invention are possible and that the details of the invention can be modified in a number of respects without departing from the inventive concept. The following drawings and description are to be regarded as illustrative in nature and not restrictive.
- The present invention and its features will be better understood by reference to the accompanying drawings, wherein:
-
FIG. 1 is a side view of a medical instrument for removing vertebral disc material from a vertebral disc space of a spine fashioned in accordance with the present principles; -
FIG. 2 is an enlarged view of a distal end of the medical instrument ofFIG. 1 particularly depicting a head thereof in the form of an auger; -

FIG. 5 is an enlarged view of a tip of the auger of the medical instrument ofFIG. 1 . - For the purposes of promoting an understanding of the principles of the invention reference will now be made to the embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the described embodiment, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates.
- Referring to
FIGS. 1-5 , there is shown a medical instrument, generally designated 10, for removing vertebral disc material (not shown), typically from within a disc space (not shown) between adjacent vertebrae (not shown) of a spine during a surgical spine procedure, particularly, but not necessarily, in minimally invasive or micro invasive surgery (MIS) via a cannula, endoscopic, tube, or the like, or a similar spine procedure. The presentmedical instrument 10 may be used in surgical procedures other than MIS procedures. Themedical instrument 10 is fashioned from one or more surgical grade materials. -
FIG. 1 depicts an overall view of themedical instrument 10, also termed a vertebral disc auger. Thevertebral disc auger 10 has aproximal end 12 configured as to define a handle or handle receptor (collectively, handle 12), ashaft 14 connected to adistal end 20 of thehandle 12, and ahead 16 fashioned as an auger connected to a distal end of theshaft 14 through aneck 24. Thehandle 12 is characterized by acylindrical body 18 sized to accommodate a hand (not shown) or a handle via a generallyconical connector 19 at a proximal end of thecylindrical body 18, and to thedistal end 20. Theconnector 19 is configured to allow connection to a handle (not seen). Alternately, a handle (not seen) may be attached to theconnector 19 as a permanent part of thevertebral disc auger 10, or the configuration as shown can be the handle. Thecylindrical body 18 is shown with anotch 21 that is configured to receive a handle. Thecylindrical body 18 may have additional notches (not shown) or other configuration(s) that would be designed to receive a handle. The notch 21 (and any additional notches/configuration(s)) provide anti-rotation of a handle with respect to thecylindrical body 18 such that rotation of the handle will rotate theshaft 14 andauger 16. Thedistal end 20 of thecylindrical body 18 is generally planar and can serve as a stop against further insertion into an MIS tube, endoscope, cannula, or the like (not shown, and collectively “cannula”) during use. Rotation of thecylindrical body 18 rotates theshaft 14 and thus theauger 16. -
FIGS. 2-4 depict various views of theauger 16. Theauger 16 is configured to cut, shave, or otherwise remove vertebral discs/disc material (not shown) from a spine (not shown), collect the shaven vertebral disc material, and remove the collected vertebral disc material. Cutting and collecting the vertebral disc material is accomplished by rotation of theauger 16. Removal of the vertebral disc material is accomplished by removing theauger 16 from the vertebral disc space and from the cannula. - The
auger 16 has a plurality of helical cutting flutes or blades for slicing into vertebral disc material. In the embodiment shown in the figures, theauger 16 has three (3)helical cutting flutes flute surface neck 24, winds or spirals around theauger 16, relative to a longitudinal axis of theshaft 14, and terminates in acutting tip 25. Each flute spirals or twists 120° from its apex (sloped surfaces) along the longitudinal axis of theshaft 14. Other numbers of cutting flutes may be provided as well as the amount of twist along the longitudinal axis of theshaft 14. Upon rotation of theauger 16, the helicity of the cutting flutes aid in advancing the auger into the disc material by creating a pathway. Each helical cuttingflute helical slot auger 16. Thehelical slots central cavity 36 within theauger 16. Thecentral cavity 36 collects cut/shaven disc material for removal. Removal is accomplished by extracting theauger 16 from the vertebral disc space and the body. -
FIG. 5 depicts an enlarged view of the cuttingtip 25 as viewed from the distal end of theauger 16. Thehelical cutting flute 27 terminates at its distal end in a cuttingapex 38. Thehelical cutting flute 28 terminates at its distal end in a cuttingapex 39. Thehelical cutting flute 29 terminates at its distal end in a cuttingapex 40. The cutting apexes 38, 39, 40 converge to form the cuttingtip 25. - In use, as the
auger 16 advances forward into the disc material through rotation of theproximal end 12/shaft 14, the helical cutting flutes 27, 28, 29 collect disc material into thehelical slots central cavity 36 for the purpose of removing the disc material. - The
shaft 14 is shown withdepth markings 22 on its outside diameter for assisting with depth reference within a patient. Other types of depth markings/references may be used. - While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only a preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected. It should be understood that while the use of words such as preferable, preferably, preferred or more preferred utilized in the description above indicate that the feature so described may be more desirable, it nonetheless may not be necessary and embodiments lacking the same may be contemplated as within the scope of the invention.
