Description

인공슬관절 수술용 시험 대퇴골 인공관절 및 경골 절골기 연결장치{ Linker For Femoral Trial And Tibial Resector In Knee Arthroplasty }Trial Femoral Joint and Tibial Osteotomy Linking Device for Surgery of Artificial Knee Joint {Linker For Femoral Trial And Tibial Resector In Knee Arthroplasty}

인체의 손상된 슬관절을 인공관절로 치환하는 수술에서 수술 후 인공관절의 수명연장과 환자의 원활한 재활을 가능케 하기 위해서 양쪽 다리 길이를 맞추는 것은 물론 변형된 부정렬의 교정은 특히 중요하다. 상기한 부정렬 교정의 성패는 최종적으로 치환될 인공관절의 제원과 같은 규격으로 변형된 슬관절에서 직육면체의 공간을 절골하고 인공 슬관절을 치환하는 것이다.In the surgery to replace damaged knee joints with artificial joints, it is particularly important to correct the misalignment of the legs as well as to adjust the length of both legs in order to extend the lifespan of the artificial joints and to facilitate the rehabilitation of the patient. The misalignment of the above-described misalignment corrects the osteotomy of the cuboid and replaces the artificial knee joint in the knee joint modified to the same specifications as the specifications of the artificial joint to be finally replaced.

본 발명은 슬관절 인공관절 치환술에서 상기한 정렬 복원을 위한 절골이 가능하도록 시험 대퇴골 인공관절과 경골 절골기를 연결장치로 연계시켜 정열을 유지시키면서 소정의 절골을 정확히 시술할 수 있는 대퇴 경골 연계식 절골술을 위한시험 대퇴골 인공관절과 경골 절골기를 연결하는 장치를 제공하기 위한 것이다.The present invention provides a femoral tibial linked osteotomy that can precisely perform a predetermined osteotomy while maintaining alignment by linking the test femur joint and the tibial osteotomy with the connecting device so that the osteotomy for restoring alignment can be performed in the knee arthroplasty. To provide a device for connecting the femoral prosthesis and the tibial osteotomy.

본 발명은 인체의 손상된 슬관절을 수술적으로 절골한 다음 인공관절로 교체하는 데 사용되는 슬관절 절골용 수술 기구에 관한 것이다.The present invention relates to a surgical instrument for knee joint osteotomy used to surgically osteotomize a damaged knee joint of the human body and then replace it with an artificial joint.

종래의 인공슬관절 치환 수술은 슬관절의 관절 면의 연골이 마모되거나 류마티즘, 관절염 등과 같은 질병으로 인해 내반 또는 외반 변형된 다리를 도 1의 왼쪽 그림과 같이 대퇴골두로부터 슬관절 중앙을 지나 발목관절 중앙을 잊는 축 즉 체중이 전달되는 기계적 축과 직각이 되도록 절골한 후 인공슬관절로 대치하는 것이다.Conventional knee replacement surgery involves forgetting the center of the ankle joint from the femoral head from the femoral head to the leg or varus deformed leg due to abrasion of the joint surface of the knee joint or disease such as rheumatism or arthritis. The shaft is replaced so that it is perpendicular to the mechanical axis to which the weight is transmitted, and then replaced with an artificial knee joint.

이때 성공적인 수술 결과를 거둘수 있는 이상적인 절골은 도 1의 오른쪽 그림과 같이 기계적 축과 정렬을 유지하면서 축에 대해 직각이고, 동시에 치환될 인공슬관절의 두께와 동일하게 직사각형 내의 빗금 친 부분을 상하 절단면이 평행하게 절골하여야 한다.In this case, the ideal osteotomy, which can achieve successful surgical results, is perpendicular to the axis while maintaining alignment with the mechanical axis as shown in the right figure of FIG. 1, and the upper and lower cutting planes are parallel to the hatched portion in the rectangle equal to the thickness of the artificial knee joint to be replaced at the same time. Should be osteotomy.

기존의 슬관절 수술 기구는 도 2의 왼쪽 그림과 같이 독립적으로 대퇴골에 정렬장치를(1) 이용하여 정렬을 맞춘 다음 수직의 핀 구멍(3)과 경사진 구멍(10)에 핀(7)을 박아 대퇴골 하단 절골기(2)를 고정시킨 다음, 절골 홈(4)을 통하여 진동 톱으로 절골한 다음 인공관절로 치환될 부분을 절골 지그를 이용하여 대퇴골을 절골하고. 경골 절골은 도 3의 왼쪽 그림과 같은 대퇴골과 무관하게 독립적으로 경골 정렬장치(5)를 설치하여 정렬을 맞추고 절골 위치를 선정한 다음 경골 절골기(6)의 수평 구멍(3)과 경사 구멍(10)에 핀(7)으로 고정하고, 절골 홈(4)을 통하여 진동 톱으로 절골한다.Conventional knee surgery instruments are independently aligned using the alignment device (1) to the femur as shown in the left figure of Figure 2, and then pins (7) in the vertical pin hole (3) and inclined hole (10) After fixing the lower femur (2), and then the osteotomy through the osteotomy groove (4), and then to the artificial joint joint to replace the femur using the osteotomy jig. The tibial osteotomy is installed independently of the femur as shown in the left figure of FIG. 3, and the tibial alignment device 5 is installed independently to align and select the position of the tibia, and then the horizontal hole 3 and the oblique hole 10 of the tibial osteotomy 6 ) Is fixed to the pin (7), and the osteotomy is cut through the cutting groove (4).

상기와 같이 대퇴골과 경골의 독립적 정렬 및 절골은 도 1의 우측과 같은 이상적인 정렬과 인공관절로 대체되는 만큼의 직사각형의 절골은 실제 수술시에는 어렵기 때문에 수술 도중 추가적인 절골이나 연조직의 박리 또는 절제에 의한 이완술이 필요한 단점이 있었다.As described above, the independent alignment and osteotomy of the femur and tibia is as ideal as the right side of FIG. 1, and because the rectangular osteotomy is difficult to perform in actual surgery, it is difficult to perform additional osteotomy or soft tissue detachment or excision during surgery. There was a disadvantage that requires relaxation.

변형된 관절의 대퇴골과 경골을 각각 독립적 절골하는 종래의 기술은 정렬과 동시에 이 정렬에 대해 수직한 직사각형의 절골이 곤란하기 때문에 본 발명은 인공슬관절 치환 수술에서 수술 자에게 절골시 정확한 대퇴골과 경골의 정렬을 복원 또는 유지토록 하면서도 아울러서 수술자가 의도하는 정확한 신전 간격으로 대퇴골 하단과 경골 상단을 직사각형으로 그리고 후방 경사각과 경골 회전을 조절하여 절골할 수 있는 대퇴 경골 연계식 절골술용 연결장치(8)를 제공함에 있다.Since the conventional technique of independently cutting the femur and tibia of the deformed joint is difficult to align and at the same time perpendicular to the alignment, the present invention provides accurate femoral and tibia It provides a femoral tibial linkage for osteotomy (8), which can be articulated by adjusting the inclination and tibial rotation of the lower femur and tibial top at the exact extension intervals that the operator intended. Is in.

본 발명의 연결장치는 변형된 관절이 복원될 수 있는 최소한의 연조직 이완술을 시행하여 정렬을 맞출 수 있도록 준비한 다음 일련의 대퇴골 절골을 시행한 다음 시험 대퇴골 인공관절(16)을 끼우고 시험 대퇴골 인공관절(16) 전면에 연결장치(8) 일단의 고정나사(19)를 이용하여 결합한 다음 반대쪽에 경골 절골기(6)를 설치하기 때문에 신전상태에서 경골 절골기(6)의 위치에 따라 신전간격을 정할 수 있고 이때 힌지(13)의 각도만큼 후방 경사각을 조절 할 수 있으며, 회전기(17)를 좌우로 회전시킴으로서 경골의 회전각을 조절할 수 있게 된다.The connection device of the present invention is prepared to be aligned by performing a minimum of soft tissue relaxation that the deformed joint can be restored, and then subjected to a series of femoral osteotomy and then inserting a test femoral artificial joint (16) and a test femoral artificial joint (16) In the front of the connecting device (8) using a set of fixing screws (19) to combine and then install the tibial osteotomy (6) on the opposite side to extend the extension interval according to the position of the tibial osteotomy (6) The rear inclination angle can be adjusted by the angle of the hinge 13, and the rotation angle of the tibia can be adjusted by rotating the rotor 17 from side to side.

도 5는 실제 슬관절 전치환 수술에 사용되는 시험 대퇴골 인공관절(16)과 경골 절골기(6)를 직선적으로 단순히 연결할 수 있는 연결장치(8)로 연결한 사진으로, 시험 대퇴골 인공관절(16) 표면에 고정나사(19)로 연결장치(8)가 고정되어 있으며 막대형의 연결장치(8)에 경골 절골기(6)를 임의의 위치에서 정지 및 고정시킬 수 있다.5 is a photograph of the test femur artificial joint 16 and the tibial osteotomy 6 used in the actual total knee arthroplasty with a connecting device 8 which can be connected simply and linearly, the test femur artificial joint 16 The connecting device 8 is fixed to the surface by a fixing screw 19, and the tibial osteotomy 6 can be stopped and fixed at an arbitrary position on the rod-type connecting device 8.

이것은 슬관절 치환수술의 어려움의 근본 원인이 6개의 자유도 즉 관절운동의 중심점을 기준으로 외반-내반, 신전-굴곡, 내-외회전, 상단-하단, 내측-외측 그리고 전방-후방으로 구분되는 변수 중에 외반-내반, 신전-굴곡 그리고 내-외회전의 3개의 자유도를 동시에 조절 할 수 있기 때문에 수술의 편의성을 크게 향상시킬 수 있으며, 상기와 같은 정확한 절골은 환자마다 상이한 해부학적 형태 변화에 용이하게 수술자가 시술할 수 있게 하고, 수술시간의 단축과 환자의 수술 후 조속한 회복 및 원활한 관절운동과 특히 부정렬 치환 수술의 경우 빈발하는 환자의 통증 증대, 삽입물의 과도 마모로 이한 수명 단축 및 재수술 위험을 방지할 수 있다.This is due to the fact that the root cause of the difficulty of knee replacement surgery is one of six degrees of freedom, namely varus-valgus, extension-flexion, inner-external rotation, upper-lower, medial-lateral and anterior-rear, based on the center of joint motion. Since the three degrees of freedom of valgus- varus, extension- flexion and inner-external rotation can be controlled simultaneously, the convenience of surgery can be greatly improved. Such accurate osteotomy facilitates the operator to easily change the anatomical shape of each patient. It can reduce the operating time, speed up recovery after surgery and smooth joint movement and increase the pain of frequent patients, especially in the case of misalignment surgery, and reduce the lifespan caused by excessive wear of the insert and the risk of reoperation. Can be.
