Description

정위 방사선 수술용 고정 프레임Fixed Frame for Stereotactic Radiosurgery
본 발명은 고정 핀의 위치를 조정 가능하게 형성하여 개두술을 실시 한 환자에게도 정위 방사선 수술을 적용할 수 있게 해 주는 정위 방사선 수술용 고 정 프레임에 관한 것이다.The present invention relates to a fixed frame for stereotactic radiosurgery that can be formed to adjust the position of the fixing pin to enable the application of stereotactic radiosurgery to patients who have undergone craniotomy.
일반적으로, 정위 방사선 수술은 신경 외과적 수술이 힘든 환자의 머리 내 작은 종양에 대해 3차원 정위좌표계를 이용하여 일시에 높은 선량을 조사시키는 방사선 치료법으로사용하는 치료기의 형태에 따라 감마 나이프와 선형가속기를 이용한 정위 방사선 수술 등으로 구분될 수 있다.In general, stereotactic radiosurgery is a gamma knife and linear accelerator depending on the type of therapies used as a radiation therapy to irradiate high doses at a time using a three-dimensional stereocoordinate system on small tumors in the head of patients with difficult neurosurgery. Stereotactic radiosurgery using the same.
이러한 정위 방사선 수술은 주변 정상조직에 대한 부작용을 최소화 하면서 목표한 종양에 고선량으로 치료 가능한 장점이 있어 널리 사용되고 있다.Such stereotactic radiosurgery is widely used because it can be treated with high dose to the target tumor while minimizing side effects on surrounding normal tissues.
한편, 정위 방사선 수술을 위해서는 환자의 머리가 치료장비에 흔들림 없이 고정되어야 하고, 방사선은 머리의 여러 방향에서 조사하되 종양에는 선량이 정밀하게 집속되어야 한다.On the other hand, for stereotactic radiosurgery, the patient's head should be fixed to the treatment equipment without shaking, and the radiation should be irradiated from various directions of the head, but the dose should be precisely focused on the tumor.
이에 따라, 정위 방사선 수술용 고정 프레임은 환자의 머리를 수용 및 고정하되, 방사선을 조사하는데 방해되지 않도록 최대한 머리를 가리지 않고 노출시켜야 한다. 또한, 머리의 무게를 안정적으로 지탱하여야 함은 물론이고 치료 중 머리가 움직이지 않도록 하여야 한다.Accordingly, the stereotactic radiosurgery fixation frame should accommodate and fix the patient's head, but should be exposed as unobstructed as possible so as not to interfere with irradiation. In addition, the weight of the head must be stably supported, and the head must not be moved during the treatment.
한편, 종래의 정위 방사선 수술용 고정 프레임은 그 내부에 환자의 머리를 수용한 후 고정 핀을 이용하여 환자의 머리를 가압하여 프레임에 환자의 머리를 고정시키도록 형성된다. 그러나, 환자의 머리를 가압하여 고정시키는 고정 핀의 위치가 고정 프레임에 체결되어 위치 조정이 되지 않아, 정위 방사선 수술을 실시하기 전에 환자가 개두술(craniotomy)을 실시한 경우 고정 핀과 수술한 쪽의 두개골이 맞닿는 문제가 있었다.On the other hand, the conventional stereotactic radiosurgery frame is formed to receive the patient's head therein and press the patient's head using a fixing pin to fix the patient's head to the frame. However, since the position of the fixing pin that presses and fixes the patient's head is fixed to the fixing frame so that the position cannot be adjusted, when the patient has undergone a craiotomy before the stereotactic radiosurgery, the fixing pin and the skull on the surgical side are fixed. There was a problem with this contact.
이렇게 되면, 개두술을 실시한 두개골이 고정 핀의 힘을 이겨내지 못하고 골절되어 심각한 뇌 손상이 일어날 수 있으므로, 환자가 정위 방사선 수술을 할 수 있는 경우에도 정위적 수술을 포기하여야만 하는 문제가 있었다.In this case, the skull subjected to craniotomy can not be able to overcome the force of the fixing pin can cause severe brain damage, there is a problem that should be given to stereotactic surgery even if the patient can perform stereotactic radiosurgery.
본 발명의 과제는 고정 핀의 위치를 조정 가능하게 형성하여 개두술을 실시한 환자에게도 이용할 수 있도록 형성된 정위 방사선 수술용 고정 프레임을 제공함에 있다.An object of the present invention is to provide a fixed frame for stereotactic radiosurgery formed to be able to adjust the position of the fixing pin to be used in patients undergoing craniotomy.

In this case, the first fixing pin 140 may be inserted in the first fixing hole 10 to be proximate or spaced apart in the direction in which the patient's head is disposed.
위치조정 프레임(150)은 전방 고정프레임(120)과 후방 고정프레임 (130) 중 어느 하나의 타단에 수평방향으로 탈착 가능하게 장착된다. 또한, 위치조정 프레임(150)에는 전방 고정프레임(120)과 후방 고정프레임(130) 중 어느 하나의 제1 고정 홀(10)들에 각각 대응되는 체결 홀(20)들과, 체결 홀(20)들 사이에 배치된 복수의 제2 고정 홀(30)들이 형성된다.Positioning frame 150 is detachably mounted to the other end of any one of the front fixed frame 120 and the rear fixed frame 130 in a horizontal direction. In addition, the positioning frame 150 has fastening holes 20 corresponding to one of the first fixing holes 10 of the front fixing frame 120 and the rear fixing frame 130, and the fastening hole 20. A plurality of second fixing holes 30 are disposed between the holes.
이와 같이, 위치조정 프레임(150)에 제1 고정 홀(10)들과 대응하는 체결 홀(20)들이 형성됨에 따라, 체결부재(170)에 의해 위치조정 프레임(150)이 전방 고정프레임(120)과 후방 고정프레임(130) 중 어느 한 곳에 체결될 수 있게 된다.As such, as the fastening holes 20 corresponding to the first fixing holes 10 are formed in the positioning frame 150, the positioning frame 150 is moved forward by the fastening member 170. And it can be fastened to any one of the rear fixed frame (130).
예를 들어, 환자가 머리의 전면부를 수술할 경우에는 도 1에 도시된 바와 같이 위치조정 프레임(150)이 전방 고정프레임(120)에 장착되고, 환자가 머리의 후면부를 수술할 경우에는 도 3에 도시된 바와 같이 위치조정 프레임(150)이 후방 고정프레임(130)에 장착되는 것이다. 이는, 환자가 정위 방사선 수술을 하려는 위치에 따라 제2 고정 핀(160)의 고정 위치를 조정하기 위한 것으로, 자세한 설명 은 후술하기로 한다.For example, when the patient is operating the front part of the head, as shown in FIG. 1, the positioning frame 150 is mounted to the front fixed frame 120, and when the patient is operating the back part of the head, FIG. As shown in the positioning frame 150 is mounted to the rear fixed frame (130). This is for adjusting the fixing position of the second fixing pin 160 according to the position where the patient is to perform stereotactic radiosurgery, which will be described later.
제2 고정 핀(160)은 위치조정 프레임(150)의 제2 고정 홀(30)들에 삽입되어 환자의 머리를 가압하여 고정시키는 역할을 하며, 적어도 하나 이상 구비 된다. 이때, 제2 고정 핀(160)은 환자의 머리가 배치된 방향으로 근접 또는 이격 가능하게 형성되어 제2 고정 홀(30)들에 삽입될 수 있다.The second fixing pin 160 is inserted into the second fixing holes 30 of the positioning frame 150 to press and fix the head of the patient, and is provided with at least one. In this case, the second fixing pin 160 may be formed to be proximate or spaced apart in the direction in which the head of the patient is disposed and inserted into the second fixing holes 30.
이처럼 위치조정 프레임(150)에 복수의 제2 고정 홀(30)들이 형성되고, 제2 고정 홀(30)들 중 일부에 선택적으로 제2 고정 핀(160)이 삽입될 수 있도 록 형성함으로써, 환자가 정위 방사선 수술을 실시하기 전에 개두술(craniotomy)을 실시하였을 경우에도 정위 방사선 수술용 고정 프레임(100)을 환자의 머리에 고정 시킬 수 있게 된다.As such, a plurality of second fixing holes 30 are formed in the positioning frame 150, and the second fixing pins 160 may be selectively inserted into some of the second fixing holes 30. Even if the patient has undergone a craniotomy before performing stereotactic radiosurgery, the fixed frame 100 for stereotactic radiosurgery may be fixed to the head of the patient.
예를 들어, 도 4에 도시된 바와 같이, 환자가 좌측 전면부에 개두술 (craniotomy)을 이미 실시하였을 경우, 개두술을 실시한 좌측 전면부와 제2 고정 핀(160)이 삽입되는 부위가 맞닿게 되면 개두술을 실시한 두개골이 그 힘을 유지하 지 못하고 골절되어 심각한 뇌 손상이 발생할 수 있다.For example, as shown in FIG. 4, when the patient has already performed a craniotomy on the left front side, when the left front side undergoing the craniotomy and the site where the second fixing pin 160 is inserted are in contact with each other. A craniotomy skull can't maintain its strength and can cause severe brain damage.
이에 따라, 도 5에 도시된 바와 같이, 환자의 좌측 전면부와 맞닿는 제2 고정 홀(30)들을 피해 우측 전면부에 위치한 제2 고정 홀(30)들에 제2 고정 핀(160)들을 삽입하게 되면, 골절의 위험 없이 정위 방사선 수술용 고정 프레임(100)을 환자의 머리에 고정시켜 정위 방사선 수술을 할 수 있게 된다.Accordingly, as shown in FIG. 5, the second fixing pins 160 are inserted into the second fixing holes 30 positioned on the right front side, avoiding the second fixing holes 30 contacting the left front side of the patient. In this case, the stereotactic radiosurgery fixing frame 100 is fixed to the head of the patient without the risk of fracture, thereby enabling stereotactic radiosurgery.
여기서, 제2 고정 핀(160)은 한 쌍으로 이루어져 개두술을 실시한 부위를 피해 제2 고정 홀(30)들에 각각 삽입되는 것이 바람직하나, 환자가 양측 모 두 개두술을 실시한 경우에는 중앙에 위치한 제2 고정 홀(30)에만 제2 고정 핀(160)을 삽입하여 머리를 고정시키는 것이 바람직하다. 이때에는 한 쌍의 제2 고정 핀(160)을 삽입한 경우보다 약 70%의 힘만 가하여 환자의 두개골에 무리한 힘이 가해지지 않도록 한다.Here, it is preferable that the second fixing pin 160 is formed in a pair and inserted into the second fixing holes 30, respectively, to avoid the site where the cranial surgery was performed. It is preferable to insert the second fixing pin 160 only in the fixing hole 30 to fix the head. At this time, only about 70% of the force is applied to the patient's skull so as not to apply excessive force to the skull of the patient than when the pair of second fixing pins 160 are inserted.
한편, 제1 고정 홀(10)들과, 제2 고정 홀(30)들 및 체결 홀(20)들의 내경에는 직경 및 피치각이 같게 형성된 나사산이 형성될 수 있다.On the other hand, the inner diameter of the first fixing holes 10, the second fixing holes 30 and the fastening holes 20 may be formed with a thread formed with the same diameter and pitch angle.

In addition, since the shapes of the twelfth fixing pins 140 and 160 are also formed in the same manner, convenience is increased by not checking the types of the fixing pins when the twelfth fixing pins 140 and 160 are fastened.
한편, 도 6에 도시된 바와 같이, 위치조정 프레임(150)은 외측방향 으로 곡면을 갖는 바(bar) 형상으로 형성되고, 체결 홀(20)들이 배치된 면이 제2 고정 홀(30)들이 배치된 면 보다 돌출되게 이루어져 양 측면에 단턱이 형성되게 이 루어질 수 있다.On the other hand, as shown in Figure 6, the positioning frame 150 is formed in a bar (bar) shape having a curved surface in the outward direction, the surface on which the fastening holes 20 are arranged the second fixing holes (30) Protruding from the disposed surface can be formed to form stepped on both sides.
이때, 위치조정 프레임(150)은 높이 22mm, 길이 130mm, 두께 10mm, 약 100mm의 곡율 반경을 갖도록 이루어져 종래의 정위 방사선 수술용 고정 프레임 (100)에 장착 가능하게 형성되는 것이 바람직하나, 이는 실시자의 필요에 따라 달 라질 수 있다.At this time, the positioning frame 150 is made to have a radius of curvature of height 22mm, length 130mm, thickness 10mm, about 100mm is preferably formed to be mounted to the conventional stereotactic radiosurgery fixed frame 100, which is the It can vary depending on your needs.
전술한 바와 같이, 정위 방사선 수술용 고정 프레임(100)은 위치조정 프레임(150)에 삽입된 제2 고정 핀(160)의 위치를 조정 가능하게 형성하여 개두술을 실시한 환자에게도 정위 방사선 수술을 가능하게 한다.As described above, the stereotactic radiosurgery fixing frame 100 is configured to adjust the position of the second fixing pin 160 inserted into the positioning frame 150 to enable stereotactic radiosurgery even for a patient who has undergone a craniotomy. do.
또한, 제12 고정 홀(10, 30)들과 체결 홀(20)들의 내경에 동일한 형상으로 이루어진 나사산을 형성함에 따라 위치조정 프레임(150)이 전방 고정프레임(120) 또는 후방 지지프레임(110)에 체결 가능해진다.In addition, as the thread having the same shape is formed in the inner diameters of the twelfth fixing holes 10 and 30 and the fastening holes 20, the positioning frame 150 is the front fixing frame 120 or the rear supporting frame 110. Can be tightened.
아울러, 제12 고정 홀(1030)들과 체결 홀(20)들의 내경에 동일한 형상으로 이루어진 나사산을 형성함에 따라 제12 고정 핀(140, 160)들의 형상 또한 동일하게 형성되어, 제12 고정 핀(140, 160)들의 체결 시 제12 고정 핀(140, 160)들의 사이즈를 일일이 확인하지 않아도 되므로 편리성이 증대된다.In addition, as the threads having the same shape are formed in the inner diameters of the twelfth fixing holes 1030 and the fastening holes 20, the shapes of the twelfth fixing pins 140 and 160 are also formed in the same manner. When fastening the 140 and 160, the size of the twelfth fixing pins 140 and 160 does not need to be checked individually, thereby increasing convenience.
