Description

Surgical device for spiral vertebral column

The present invention relates to a surgical instrument for vertebral disease, and it is a surgical instrument for vertebral disease for strengthening soft vertebral bone by injecting a bone reinforcing agent into the vertebral bones compressed by osteoporosis or trauma. Although the surgery was performed by incision and screw fixation, the development of this instrument is a design for a surgical instrument that can complete all operations under local anesthesia rather than general anesthesia by drilling a small hole on the back without incision. .

Aging elderly and postpartum women often develop osteoporosis and can cause compression fractures due to trauma. We can bring about pressure of organ. Gradual progression can lead to disorders such as full back flexion or hip fracture due to compression fractures and nerve compression.

In the case of spinal compression fracture due to osteoporosis, which has many problems as described above, the bone mineral density as a bone graft material can be directly added to the vertebral bone by maintaining the stability of the vertebral bone with respect to the vertebral bone. Spine augmentation has been performed to reinforce or harden broken vertebral bones during compression fractures due to trauma. In the formation of an injection hole for inputting a bone reinforcing agent as a bone graft material, an insertion hole (groove) is formed in the vertebral bone by applying an external impact using a hammer or the like with a sharp awl-shaped device against the vertebral bone. In this state, the insertion hole allows bone cement to enter the vertebral bone. In the process of forming the input hole, the subject is not only accompanied by the pain of enduring severe pain, but also by using the primitive method of the blow, it is impossible to form a precise and detailed input hole, so that the bone for the corresponding vertebral bone is a post work. Not only do not put the cement properly or inadequately inject sufficient amount of cement, but the risk of leakage of the injected bone cement cannot be expected, and the risk of the procedure can be implied. As a result, the operator had to put a lot of mental burden, which could cause the failure of the operation.

Therefore, the object of the present invention is to solve the problems of the conventional spinal bone disease treatment equipment that had to be made by a complicated and difficult procedure when injecting a bone stiffener to the vertebral bone of the patient in need of spinal surgery as described above. In order to solve the problem, by using the surgical instruments consisting of a plurality of surgical tubes and rods in order to form a bone cement input hole for the vertebral bone and to input bone cement through the input hole at the same time The present invention provides a surgical instrument for spinal bone disease that allows the release of a patient from pain due to a lot of risks and external shocks, and for a spine surgery for accurate and safe treatment of spinal bone disease without fear or fear at all.

In order to achieve the above object, the surgical instrument for spinal bone disease of the present invention (FIG. 1) is a guide auger for skin penetration (1) having a locking piece (2) at the top, drill rod (8) for injection hole formation, Osteo-intensifier supply pipe 12 to allow the bone reinforcing agent to be supplied through the inlet 11 by the push rod 16, guide needles 7 used for skin penetration together with the guide awl, and the coupling portion at the top (6) and the engaging portion 6 of the upper end to the engaging piece 2 of the guide awl 1 for skin penetration is characterized in that it consists of a handle (3).

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.

In the accompanying drawings, Figure 1 is an exploded perspective view showing the configuration of the surgical instrument according to the present invention, Figure 2 is a guide through the skin for the configuration showing the configuration of the surgical instrument according to the present invention, Figure 3 is a 3A to 3B are enlarged views showing the screw grooves of the guide needles showing the configuration of the treatment instrument according to the present invention, and FIG. 4 is an enlarged view of the head of the guide awl according to the present invention. 5 is an enlarged view of the guide needle coupling portion, Figure 6 is a drill rod, a pipe, a push rod.

The configuration is composed of a guide auger (1), a guide needle (7), a drill rod (8), a pipe for supplying bone reinforcement (12), a push rod (16) for pushing the bone reinforcement. 7 to 10 is an exemplary view of the procedure according to the procedure using the instrument according to the present invention.

The guide awl and the guide needle are integrated into the patient's affected spinal vertebrae slightly, and after being slightly driven, turn the guide clockwise along the screw-shaped groove at the bottom of the guide needle to the desired position without external impact. ) Get stuck.

At this time, when the coupling portion (A) of the upper guide needle in the coupling groove (2) of the upper guide awl is rotated to 45 ° and rotated back to its original position, the random separation of the guide awl and the guide needle is prevented.

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 of the design in sequence, the guide auger (1) is inserted into the guide needle (7) and combined with each other and then inserted into the affected part of the spine, the pointed portion of the guide auger (1) And the guide awl (1) and guide needle (7) coupled together while the spiral structure of the guide needle is slightly embedded in the vertebrae, and the spiral structure (5) of the guide needle is easily The needle can be drilled through the bone and secured to the desired position.

The guide auger 1 is then rotated in the opposite direction at the time of engagement with the guide needle 7 to release the coupling, and then the drill rod 8 is inserted into the guide needle and rotated to inject the bone reinforcement to the affected part. The hole for the insertion of the dragon pipe 12 is drilled.

At the same time, the bone reinforcing agent in a state of low viscosity is injected into the pipe 12 using a syringe. Over time, the bone stiffener slowly hardens, checks the viscosity of the bone stiffener injected into the pipe, removes the drill rod inserted into the guide needle in a solid state until it is safe to flow, and then back into the guide needle (7). The pipe into which the bone reinforcing agent is injected is inserted, and the osteotensifier in the pipe 12 is pushed into the affected part of the vertebrae by the push rod 16. In the same way, inject the desired amount of bone mineralizer into the pipe with bone mineralizer, remove the pipe (12) and push rod (16), and turn the guide needle (7) in the reverse direction at the time of insertion. Remove

As can be seen from the above description, the present invention is an operation that can minimize the pain of the patient in the surgical instrument for vertebral disease, and thus only 1 cm of the hole is performed, so there is no need for a blood transfusion and recovery is quick. Early return to society is possible and freed from the mental and economic burden of long hospitalization. There is a method that can be treated with similar products, but the risk of surgical failure of about 20%, and the hammer must be inserted into the pipe, so the risk is increased that much psychological burden both patients and operators.

The present invention is designed to prevent the risk of the flow of bone stiffeners to move to other tissues, and to prevent the risk of penetrating into the abdomen and pain from the impact of the hammer hit the spine. In addition, the operator can finish the procedure in a stable state, the subject is expected to be freed from the fear that comes from the sound of the instrument, such as the hammer sound.
