Cage surgical system for bone fusion

Abstract

The cage handle serving as an endoscope of the present invention includes a lens and an optical cable, and can perform surgery while accurately and clearly confirming the impact in front of the cage. Since a separate endoscope or X-ray as in the prior art is not used, the surgery is simple, efficient and economical.

Description

Technical Field

[0001] The present invention relates to a cage surgery system for bone fusion surgery. More specifically, the present invention relates to a cage surgery system for bone fusion surgery, in which the cage handle realizes an endoscope function, so that the insertion route and the surrounding affected part can be clearly confirmed when performing cage surgery on the spine. Background Art

[0002] The surgery of inserting a cage into the position where the diseased intervertebral disc of the spine is removed or in the case of spondylosis to fix the vertebrae is called "intervertebral bone fusion". The main body of the cage includes a spiral protrusion similar to a screw, and a plurality of small holes are drilled through it. The material of the cage is titanium or retinol, and it is manufactured by processing and 3D printing. When inserting the cage, the upper and lower vertebrae are ground around the intervertebral disc, and then the bone fragments are inserted into the cage and rotated like a screw, and then firmly inserted after being fixed to the handle or easily attached to a special handle. Although the cage fixes the upper and lower vertebrae at first, after about 3-4 months, the bones in the cage grow and naturally attach to each other.

[0003] In the past, bone fusion surgery was performed by cutting open the back, but recently, a certain space is opened to allow the use of surgical tools, and the cage is inserted through the space. However, when inserting the cage, it is impossible to see or confirm the path through the endoscope, so the cage is inserted by the operator's feeling.

[0004] Figure 6 (a) shows the cage handle H' used when inserting the cage. Figure 6 (b) is an enlarged view of the front end of the cage handle H'. Figure 6 (c) is a diagram showing a cage handle H' being used and a cage C' being positioned at the intervertebral disc.

[0005] When using the conventional cage handle H', the following method is used: while inserting the cage into the affected part, the operator inserts it while looking at the X-ray screen, or a hole is made on the waist side, and an endoscope is inserted thereto to observe the cage. The problem is that when the cage is first inserted, it is impossible to confirm whether there are spinal nerves, so special attention is required, and only X-ray images are relied on.

[0006] Figure 7 The cross-sectional view of the endoscope 1' is disclosed in the applicant's prior patent No. 10-1681451. The working channel 130' through which the surgical tool passes occupies most of the space of the tube 100'. A camera or lens 110' and a cleaning channel 120' are formed at the lower part of the working channel 130', and an optical fiber 140' which can be used as a light source is arranged in the remaining space.

[0007] In the present invention, the cage handle is combined with the function of the endoscope, thereby epoch-makingly improving the structure of the cage handle. Or, on the other hand, it can also be said that it is an invention related to a new type of endoscope that can be directly attached to the cage and used. Summary of the invention

[0008] Therefore, an object of the present invention is to provide a special cage handle or endoscope and a system including the same, wherein a small endoscopic camera is installed in front of the cage during spinal fusion surgery, so that the operator can observe whether there are any nerves or obstacles while inserting the cage into the affected area.

[0009] In order to achieve the above-mentioned purpose, the present invention provides a cage handle for spinal fusion surgery, which includes a rotatable rotating handle in the center of the cage handle, a tube is extended long in front of the rotating handle, a coupling portion for coupling with the cage is provided at the front end of the tube, a thread for coupling with the cage is formed on the outside of the coupling portion, the cage handle is connected to a camera connector and an LED connector or an optical cable of a light source device through a cable, a lens is provided at the center of the inside of at least the coupling portion of the tube, an optical fiber is arranged outside the lens, and a cage is installed outside the optical fiber in a detachable manner.

[0010] A through hole for mounting bone fragments is formed on the center of the cage, which penetrates the front and back to form a passage, and a coupling part can be coupled to the passage.

[0011] The cage is open and includes: a front end portion of the cage, which is tapered toward the front center; a cage tight connection portion, which is extended in a form connected to the front end portion of the cage and has a thread formed on the outside; and a cage sleeve, which is formed in a form connected to the cage tight connection portion and has an outer surface without a thread. The combination of the cage handle in a form corresponding to these respectively includes a front end portion, a tight connection portion, and a sleeve, wherein the front end portion is tapered toward the front center; the tight connection portion is extended in a form connected to the front end portion and has a thread formed on the outside; the sleeve is formed in a form connected to the tight connection portion and has an outer surface without a thread. The front end portion of the cage handle is pushed into the passage, so that the cage handle rotates and gradually moves forward, so that the thread can be tightly connected with the thread of the cage tight connection portion.

[0012] In addition, the present invention provides a cage surgical system for spinal fusion surgery, comprising: a console connected to a cage handle via a cable and equipped with a camera connector and an LED connector; and a display for viewing images transmitted from the cage handle.

[0013] According to the present invention, an effect is provided in that a cage surgical system for spinal fusion surgery is provided, which allows accurate and clear observation of the affected part during spinal surgery, and the cage can be easily and economically disassembled.

[0021] The sleeve 30c is provided with an outer surface 64 without threads. When the two parts are combined, the front end 30a of the cage handle 2 is pushed into the passage Cb, for example, the cage handle 2 is rotated clockwise and gradually moved forward, so that the threads 32 are completely locked and combined with the threads of the cage close connection part C2. Then, the lens 34 and the optical fiber 36 are stored in the front end C1 of the cage, and the front is exposed and ready for lighting and shooting. The cover between the inner surface of the tube 20 and the outer surface 64 is inserted into the cage sleeve C3, so that the cage C is fixed to the cage handle 2.

[0022] The coupling part 30 may be formed integrally with the tube 28, or may be manufactured and supplied separately from the tube 28. If the type of the cage C is different, the shape of the coupling part 30 may be changed accordingly.

[0023] The cage surgery system 1 of the present invention is not only suitable for the waist, back, etc., but also suitable for the joints of the cervical spine.
