The present invention relates to a surgical instrument for vertebral disease, which is used to inject a bone stiffener into the vertebra when it is necessary to inject a bone stiffener into the vertebra due to osteoporosis, trauma, or other diseases. In the past, there was no device for injection, so the diseased part was largely incised and operated.However, the device was designed to perform surgery under local anesthesia rather than general anesthesia by drilling a small hole in the back without cutting the affected part. It is designed for one surgical instrument to finish it all.

Older women and women after childbirth mainly develop osteoporosis, and there are many cases of compression fractures caused by trauma.However, if the disease is caused by fractures of the vertebrae for any reason, it causes deformation of the body and causes severe pain. It can also bring pressure. Gradual progression can lead to disorders such as lower extremity paralysis due to nerve progression and progression of vertebral disease in which the back is bent completely forward or compression fractures. Bone reinforcement is injected in the form similar to flour dough, but coagulates at a rapid rate, which causes considerable difficulty and danger in injecting with a syringe.

In the case of vertebral diseases or compression fractures that have many problems, spinal surgery is performed by directly injecting a bone strengthening agent that can maintain stability in the vertebral bone, or by hardening the vertebral bone even in the case of trauma. As described above, the above-described spinal surgery is performed by inserting a sharp awl-shaped instrument into the vertebral bone and hitting it using a hammer or the like when forming an injection hole for injecting a bone stiffener into the vertebral bone. Since the injection hole (groove) is formed in the vertebrae, bone reinforcing agent is injected into the vertebrae through the injection hole, so during the formation of the injection hole, the patient is accompanied with secondary pain, which must endure severe pain caused by the blow. In addition, the use of the primitive method of blow is impossible to form a precise and fine injection hole. For this reason, the operator had to have a lot of mental burden, which could cause the failure of the operation.

Therefore, the purpose of the present invention is to use the procedure equipment consisting of a plurality of surgical tubes and a surgical rod in the vertebral bone of the patient that requires a spinal surgery as described above, the formation of bone cement injection hole for the vertebral bone and In addition to the injection of bone cement through the injection hole, the patient's release from the pain and external shock of the procedure and both the patient and the doctor are able to accurately and safely treat the spine disease without fear or fear. It is to provide a surgical instrument for spinal bone disease to make the spinal surgery for.

In order to achieve the above object, the surgical instrument for spinal bone disease according to the present invention (FIG. 1) includes a guide auger 10 for skin penetration with a handle having a coupling groove 12 at the top, and an injection hole forming drill. The rod 31, the bone mineralizer supply pipe 41, which allows the bone reinforcement agent to be supplied through the inlet by the push rod 51, and the guide awl 10 with the handle are inserted into one piece to be used simultaneously. The needle 21 and the coupling groove 23 of the upper end is inserted into the coupling groove 12 of the guide awl 10 for skin penetration.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

1 is an exploded perspective view showing the configuration of a surgical instrument according to the present invention is a view for explaining the sequential coupling and use state. 2 is a view for explaining the coupling method of the guide needle 21 and the guide auger 10 of the surgical instrument according to the present invention and Figure 3 is a representative view of the guide needle 21 and the guide auger 10 is separated The figure is rotated without being inserted. 5 is a view for explaining the structure of the drill rod 31 for inserting into the guide needle 21 to drill the life-saving bone, Figures 4a to 4b is a spiral groove 22 formed on the outer peripheral surface of the guide needle 21 The outer circumferential surface of the guide needle 21 is a part 26 protrudes to the outside and a part of the groove 27 is recessed inward. FIG. 6A is a view in which a drill rod 31 is inserted into the guide needle while the guide needle 21 is inserted to make a hole in the affected part of the bone. FIG. 6B is a bone cement injected after the drill rod 31 is removed. The feed pipe 41 is inserted and FIG. 6C is a view of pushing the bone cement of the feed pipe 41 into the push rod 51. 6D is a view of removing the guide needle 21 and the guide auger 10 after inserting the guide auger back into the guide needle 21 after pushing all the bone cement.

The configuration is made of guide auger 10, guide needle 21, drill rod 31, supply pipe 41 for supplying bone reinforcement, push rods 51 for pushing the bone reinforcement.

The guide auger 10 and the guide needle 21 is slightly stuck in the affected spine of the patient in a state in which the guide auger 10 and the guide needle 21 are united, and after the guide auger (10) 21, the guide needle 21 is lodged to the desired position of the bone without the external impact along the spiral groove 22 of the lower outer peripheral surface.

At this time, when the coupling part 23 of the upper guide needle is inserted into the coupling groove 12 of the upper part of the guide auger 10 while being rotated back to its original position, the separation of the guide awl and the guide needle is prevented. Will be.

This is to prevent the inconvenience that the guide awl and guide teeth are randomly separated and moved separately from each other during the procedure.

When the description of the use thereof in the design of the design in order to insert the guide auger (10) into the guide needle (21) to be combined with each other and then inserted into the affected part of the spine, in this case the guide auger (10) and The guide needle 21 reaches the vertebrae and, in the state where the spiral grooves 22 of the guide needles are slightly driven into the vertebrae, when the combined guide awl 10 and the guide needle 21 are rotated together, the guide grooves spiral guide grooves. (22) can easily penetrate the vertebrae and securely guide the needle 21 to the desired position.

After the guide auger 10 and the guide needle 21 is combined by releasing the guide by turning the handle of the guide auger 10 in the opposite direction at the time of coupling, only the guide auger 10 is removed and drilled back into the guide needle 21. The rod 31 is inserted and rotated to drill a hole for insertion of the bone reinforcing agent supply pipe 41 to the affected part.

At the same time, the bone reinforcing agent in a state of low viscosity is injected into the supply pipe 41 by using a syringe. Over time, the bone reinforcing agent is hardened and after confirming the viscosity of the bone reinforcing agent injected into the supply pipe 41, the drill rod 31 inserted into the guide needle 21 is removed while being solidified to a safe state without any risk of flowing. After inserting the supply pipe 41 into which the bone reinforcing agent is injected into the guide needle 21 again, the reinforcing agent in the supply pipe 41 is pushed into the affected part of the vertebra with the push rod 51. In the same way, after injecting the desired amount of bone strengthening agent into the vertebrae with a pipe in which the bone strengthening agent is injected, the supply pipe 41 and the push rods 51 are removed, and the guide needle 21 is inserted in the reverse direction when the needle 21 is inserted. Turn it away safely from the vertebrae.

As can be seen from the above description, the present invention is a surgical instrument that can be performed to minimize the pain of patients in the surgical instrument for vertebral disease, and because only 1cm hole is performed, there is almost no bleeding, so no blood transfusion and recovery is quick. There is an advantage. Early return to work is possible and freed from the mental and economic burden of prolonged hospitalization. Although there is a method that can be performed with similar products, the operation failure rate is about 20%, which is high, so the risk is increased, and the guide needle and the pipe must be inserted by hitting with a hammer. There is a big disadvantage.

The present invention prevents the risk of bone mineralizers flowing to other tissues by the injection of high viscosity bone mineralizers, and also prevents the risk of penetrating into the abdomen and pain resulting from the impact of hammering the vertebrae. It is designed to be. In addition, the operator is able to finish the procedure in a stable state, the subject is expected to be freed from the fear of pain caused by the sound of the instrument, such as the hammer and the blow.
