Description

SURGICAL INSTRUMENT FOR USE IN SPINAL SURGERY OPERATIONS
Technical Field
The present invention relates to a surgical instrument for use in spinal surgery operations.
More particularly, the invention relates to a surgical instrument that makes it possible to make the paravertebral muscles divaricate momentarily, and with minimal intervention, for the insertion of transpedicular screws. Background Art As is known, the placement of transpedicular screws entails providing an incision at the level of the spinal column of the patient, exposing the spinal column, so as to be able to access the mamillary processes, i.e., the intersection between the transverse process and the lower third of the articular processes, in order to be able to position the transpedicular screws at the lower edge of the articular processes at the junction with the transverse process.
This operation is normally performed by providing an incision, as mentioned, and by making the paravertebral muscles divaricate with more or less invasive divaricators. However, divarication of the paravertebral muscles is today still performed manually by the surgeon by using divaricators with "hands" or with more or less invasive prongs on the muscle bundles, and it is further not possible to perform a selective divarication of the muscle bundles.
Traditional divaricators open the paravertebral muscles with a broad detachment thereof and therefore with considerable pain and bleeding to the patient in the postoperative phase. Disclosure of the Invention
The aim of the present invention is to provide a surgical instrument for use in spinal surgery operations that makes it possible to facilitate the divarication of the paravertebral muscles, thus clearing for the surgeon a work area that is adequate for positioning said transpedicular screws.
Within this aim, an object of the present invention is to provide a surgical instrument that allows making the paravertebral muscles divaricate only momentarily for the insertion of transpedicular screws. Another object of the present invention is to provide a surgical instrument that can be handled easily by the surgeon and offers great assurance of reliability as regards the action performed.
Another object of the present invention is to provide a surgical instrument that is highly reliable, relatively simple to provide and has competitive costs.
This aim and these and other objects that will become better apparent hereinafter are achieved by a surgical instrument for use in the surgical operation for positioning the transpedicular screws in the spinal column of a patient, characterized in that it comprises a handle portion that is adapted to be gripped by the surgeon and terminates, at one end, in a curvilinear blending portion that terminates in a fork-like portion. Brief description of the drawings
Further characteristics and advantages of the invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment of the surgical instrument according to the present. invention, illustrated by way of non-limiting example in the accompanying drawings, wherein:
Figure 1 is a perspective view of a surgical instrument according to the present invention; Figure 2 is a perspective view of a method of using the surgical instrument according to the present invention;
Figure 3 is a view of the use of the surgical instrument according to the invention for making the paravertebral muscles divaricate temporarily;
Figure 4 is a sectional view of the use of the surgical instrument according to the present invention. Ways of carrying out the Invention
With reference to the figures, a surgical instrument according to the present invention, generally designated by the reference numeral 1 , comprises a handle portion 2, which is conveniently shaped so that it can be gripped easily by the surgeon and terminates, at one end, in a curvilinear portion 3 that in turn terminates in a fork-like end 4.
Conveniently, the fork-like end 4 has a pair of lateral tips 4a, which are mutually blended into a curvilinear profile 4b.
The lateral tips advantageously have beveled ends. The fork portion 4 lies on a plane that is substantially parallel to the plane on which the handle portion 2 lies, with the curvilinear blending portion 3 accordingly blending two planes in which the handle portion 2 of the surgical instrument 1 and the fork-like portion 4 lie respectively.
Conveniently, the fork-like portion 4 is used, during the surgical procedure, for insertion in the transverse processes and thus for performing a sort of divarication as shown in Figure 5, of the paravertebral muscles 6, thus making it possible to expose the spinal column 7 on which the surgeon can perform the required operation, such as for example inserting transpedicular screws, which are not shown in the figures. Therefore, the instrument according to the invention allows divarication of the paravertebral muscles 6, by using simultaneously a plurality of such instruments, for example two for each side of the spinal column, as shown in Figure 3, maintaining this divarication as long as necessary. Substantially, the fork portion 4 is arranged at, and so as to straddle, the transverse process and therefore the surgeon can perform a lever-like action by supporting the curvilinear blending portion 3 of the surgical instrument, so as to make the paravertebral muscles divaricate, as shown in Figure 3. In practice it has been found that the surgical instrument according to the present invention fully achieves the intended aim and objects, since it allows divarication of the paravertebral muscles, clearing a sufficient area of the spinal column so that the surgeon can perform the surgical procedure of positioning transpedicular screws with minimal muscular injury. The surgical instrument thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
Moreover, some details may be replaced with other technically equivalent elements. In practice, the materials used, as well as the contingent shapes and dimensions, may be any according to requirements and to the state of the art.
The disclosures in Italian Patent Application No. MI2008A002080 from which this application claims priority are incorporated herein by reference.
Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
