TECHNICAL FIELD
The present invention relates to a surgical instrument set for spinal surgery, and more particularly, to a surgical instrument set for single port spinal surgery which is joined with an endoscope and secures a surgery space through a single port to minimize invasion and replaces a surgical instrument with instruments having a variety of functions and shapes according to the purpose of surgery to reduce time consumed for surgery and a method of using the same.
BACKGROUND ART
Generally, spinal stenosis is a disease in which the spinal canal that is a path through which the spinal cord passes narrows due to an influence of anaplastia or the like and presses the spinal cord, and thus causes a variety of neurological indispositions such as pseudoclaudication of the cauda equina or nerve roots and the like. Central spinal stenosis that is a type of spinal stenosis occurs because thickened facet joints in a disk region invade the spinal canal, a height of the disk is lowered, a vertical length of the spinal canal is reduced, and thus soft tissue such as a yellow ligament, a facet joint membrane, a longitudinal ligament, or the like is thickened or ossified and occupies a considerable part of a lateral cross section of the spinal canal. To treat the corresponding disease, a laminectomy, a partial laminectomy, and the like which are surgeries for physically widening the stenosed spinal canal are performed.
Generally, in such surgical removal, a lamina of vertebral arch, a yellow ligament, and facet joints may be surgically removed or partially removed to remove factors oppressing a nerve element, and general decompression and synosteotomy including instrumentation and osteoplasty may be performed to prevent segmentation instability which may occur due to the removal. However, when this is performed, there are problems such as a delay of a surgery time, an increase in blood loss of a patient, premature anaplastia of vertical segmentation of an agglutination region, and the like. It is a current tendency to utilize a minimally invasive technique to remedy these problems.
Decompression utilizing a minimally invasive technique is a surgery method of removing a lesion area such as a thickened yellow ligament by inserting an endoscope and a surgical instrument through a minimum skin incision (2 mm to 5 mm), which is performed with minimal invasion, instead of directly opening the lesion area and has advantages such as less nerve synechia caused by a postoperative injury, the possibility to perform the surgery with local anesthesia with no risk of paralysis, little sequela, and a short recovery time.
As an example of utilizing the minimally invasive technique, Korean Patent Registration No. 10-1441320 discloses a surgical instrument set for performing minimally invasive endoscopic spinal surgery. However, since a publicly known conventional decompression treatment utilizing minimal invasion is generally performed by inserting an endoscope and a surgical instrument into different ports and uses two ports, an invaded area increases and there is a risk of an occurrence of unnecessary damage inside the human body due to the endoscope inserted to observe the surgical site.

Referring to FIG. 1, a surgical instrument set for a single port spinal surgery includes a punch 100, an intubator 200, an endoscope 300, and a surgical instrument 400. In more detail, the surgical instrument 400 may be replaced, according to the goal of surgery, with a forceps 410, an ultrasonic instrument 420, and a laser instrument 430, and may be replaced with any other surgical instrument appropriate for the goal of surgery. The punch 100, the intubator 200, the endoscope 300, and the surgical instrument 400 will be described below in detail with reference to FIGS. 2 to 7.
FIG. 2 is a perspective view illustrating the punch 100 according to one embodiment of the present invention.
The punch 100 is an instrument configured to form a treatment hole H in the skin above a surgery target part T to allow the surgical instrument 400 to approach the surgery target part T.
In more detail, the punch 100 is an instrument configured to form a treatment hole H at a position at which a shortest distance from the skin to a thickened yellow ligament that is the surgery target part T can be secured or at a position from which a path for minimizing damage to internal organs can be secured.
Referring to FIG. 2, the punch 100 may have a long rod shape. A head portion 110 having a shape capable of easily entering the surgery target part T while forming the treatment hole H and of minimizing body injuries may be provided on the one end of the punch 100. In detail, the head portion 110 may be formed to be sharp enough to cut and enter the skin or may be formed to have a dull and blunt surface to minimize bodily injury. In more detail, the head portion 110 may have a conic shape having a width that gradually decreases toward the one end.
As an embodiment, the punch 100 may be implemented to have a first length L1 of 200 mm to 300 mm which is an entire length from a fore end to the other end of the punch 100 and to have a diameter of 5 mm to 6.75 mm. Here, most preferably, the first length L1 may be 240 mm to be most adequate for approaching the thickened yellow ligament that is the surgery target part T from the treatment hole H and the diameter may be 5.75 mm to minimize a size of the treatment hole H, but they are not limited thereto and may be provided depending on a position of the surgery target part T and the degree of invasiveness.
FIG. 3 is a perspective view illustrating the intubator 200 according to one embodiment of the present invention.
The intubator 200 is a device configured to secure a space (path) from the treatment hole H to the thickened yellow ligament that is the surgery target part T to allow the endoscope 300, the surgical instrument 400, and the like which will be described below in detail to enter. In detail, since the intubator 200 has a tubular shape and is inserted from the other end of the punch 100 along an outer circumferential surface of the punch 100, even when the punch 100 which has been inserted is removed, it is possible to secure a space for allowing the endoscope 300 and the surgical instrument 400 to enter. That is, the one end of the intubator 200 may be inserted into the treatment hole H to allow the one ends of the endoscope 300 and the surgical instrument 400 to be inserted into the other end of the intubator 200 having a tubular shape to secure the space for allowing the endoscope 300 and the surgical instrument 400 to enter. Here, to prevent parts of the body or internal organs from being injured or to prevent the inside of the intubator 200 from being contaminated through a gap between joining portions of the intubator 200 and the punch 100, a distance between the outer circumferential surface of the punch 100 and an inner circumferential surface of the intubator 200 may be formed to be minimized. To this end, the intubator 200 may be implemented to have an outer diameter of 6 mm to 7 mm.
