본 발명은 척추고정장치의 시술기구에 관한 것으로, 보다 자세한 설명으로는 정형외과적인 척추병변을 가지고 있는 환자의 개별 척추에 척추고정나사를 이식한 이 후, 상기의 이식된 척추고정나사의 헤드부에 최소 침습 적으로 로드를 삽입하기 위한 시술기구에 관한 것이다.The present invention relates to a surgical instrument of the spinal fixation device, and in more detail, after implanting the spinal screw into the individual spine of a patient having an orthopedic spinal lesion, the head portion of the implanted spinal screw It relates to a surgical instrument for inserting the rod minimally invasive.

상기의 척추고정장치는 과도한 육체노동으로 인한 척추 이상과, 고령에 따른 퇴행성 척추 이상이 발생한 환자에게 시술하여 척추의 해부학적인 복원 및 안전성을 확보하는 시술장치로서, 보다 자세한 구조의 설명으로는 척추골에 이식되는 척추 고정나사, 개별의 척추를 연결하는 로드, 상기의 척추고정나사와 결합되는 체결나사를 포함하는 것을 특징으로 한다.The vertebral fixation device is a surgical device to ensure the spinal anatomy and safety of the spine by treating a patient with spinal abnormality caused by excessive physical labor and degenerative vertebral abnormality due to old age. Implanted spinal fixing screw, a rod connecting the individual spine, characterized in that it comprises a fastening screw coupled to the spinal fixing screw.

이하 종래의 척추고정장치의 시술기구 및 방법을 설명하면 다음과 같다.Hereinafter, a description will be given of a conventional apparatus and method for spinal fixation.

종래에는 환자의 척추병변 부위를 의사의 시야를 확보할 만큼 외과적 시술도구를 사용하여 최소한으로 절개한 후 시술이 집도 되었다.Conventionally, the procedure was performed after making a minimal incision using a surgical surgical tool to secure a doctor's field of view of the spinal lesion of the patient.

상기의 일반적인 절개술에 의한 척추고정장치의 이식은 임상의사로 하여금 상당히 숙련된 술기를 요구한다.The implantation of the spinal fixation device by the above general incision requires the clinician to be quite skilled.

상기의 일반적인 절개술에 의한 척추고정장치의 이식은 시술 중 혈액의 과다 배출 및 연부조직의 과다 손상 등의 시술 적 변수에 의해서 일관된 시술의 안전성 확보가 어려운 측면이 있다.The implantation of the spinal fixation device by the general incision is difficult to ensure the safety of the procedure consistent with the surgical parameters such as excessive discharge of blood and excessive damage of soft tissue during the procedure.

최근에는 척추병변을 가지고 있는 환자의 환부에 최소한으로 구멍을 내어 별도의 절개가 필요 없는 간단한 시술이 가능하게 되었다.In recent years, a simple procedure without the need for a separate incision is possible because the hole of the patient with a spinal lesion is minimally punctured.

그런데, 상기의 최소한의 구멍 절개만을 하여 시술할 경우, 절개구멍을 통하여 몸속에 척추고정나사를 이식하고, 척추고정나사 헤드부에 로드를 체결하는 것은 임상의로 하여금 충분한 시야 확보를 불가능하게 하여, 척추고정장치의 시술에 있어서 매우 정교한 숙련도와 술기를 필요로 한다.However, when the procedure is performed with only the minimum hole incision, implanting the spinal screw into the body through the incision hole and fastening the rod to the spinal screw head part make it impossible for the clinician to secure a sufficient field of view. The procedure of spinal fixation requires very sophisticated skill and skill.

따라서, 최근에 환자의 환부를 최소한으로 절개하면서 시야가 충분히 확보되지 않은 상황에서도 간단하고 용이하게 척추고정장치를 안전히 시술할 수 있는 척추고정장치의 시술기구와 방법의 필요성이 증대되고 있다.Therefore, in recent years, the necessity of the surgical instruments and methods of the spinal fixation device which can safely and easily perform the spinal fixation device even in a situation where the vision of the patient is minimized while the incision is minimal.

한편, 종래의 척추고정장치의 시술에 있어서 로드를 척추고정나사의 헤드부에 삽입하여 체결나사로 고정할 때, 이식되는 부위 척추의 각도에 따라 도구를 이용하여 로드를 구부려 이식하게 된다. Meanwhile, in the conventional spinal fixation device, when the rod is inserted into the head of the spinal fixation screw and fixed with a fastening screw, the rod is bent and implanted using a tool according to the angle of the spine to be implanted.

그런데 상기의 구부려진 로드는 도구에 의하여 외력을 받은 상태이기 때문에 로드의 피로파괴 한도를 낮추어 환자에게 이식 후 장기간 사용 시, 몸속에 이식된 로드가 부러져 환자에게 위해를 가하는 단점이 있다..However, the curved rod has a disadvantage in that the rod is implanted in the body when it is used for a long time after lowering the fatigue failure limit of the rod because it is in an external force state by a tool, thereby causing damage to the patient.

따라서 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 고안된 것으로 본 발명의 목적을 다음과 같이 상세히 설명하겠다.Therefore, the present invention is designed to solve the problems of the prior art as described above will be described in detail the object of the present invention.

본 발명의 목적은, 척추에 이식된 상기의 척추고정나사의 헤드부에 상기의 일자형 로드를 신속하고 용이하게 삽입하여 상기의 체결나사를 이용하여 결합시키는 최소 침습적 시술기구를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a minimally invasive surgical instrument for fastening and easy insertion of the straight rod into the head portion of the spinal fixation screw implanted in the spine to be coupled using the fastening screw.
