Description
본 고안은 척추압박골절을 치료하기 위한 성형술에 사용되는 골시멘트 주사용 천자침세트에 관한 것이다.The present invention relates to a puncture needle set for bone cement injection used in plastic surgery for treating spinal compression fractures.
척추압박골절은 골다공증으로 유발되며, 골밀도가 낮은 척추체가 가라앉아 척수신경에 압박을 가하면 요통이 수반된다. 1980년대 후반 프랑스에서 최초로 개발된 시공법은 척추체의 다공층에 골시멘트(PMMA : polymethylmethacrylate)를 주사함으로써 침강된 다공층을 복원시켜 통증을 해소하는 방식이다. 이러한 시공법은 현재에도 널리 사용하고 있다.Compression fractures are caused by osteoporosis, and low back bone vertebral bodies sink and pressure on the spinal nerves is accompanied by back pain. The construction method first developed in France in the late 1980s is a method of relieving pain by restoring the settled porous layer by injecting bone cement (PMMA: polymethylmethacrylate) into the porous layer of the vertebral body. This construction method is still widely used today.
일반적으로 척추압박골절을 시술함에 있어서는 먼저 가이드핀을 타격하여 근육과 척추체에 천자침이 인입될 수 있는 통로를 열거나 천공하고 여기에 천자침으 인입하여 천자침에 골시멘트를 주사기나 건(gun)으로 주사한다. 다만 골시멘트가 주입될 공간을 확장시키기 위하여 풍선을 이용하는 것이 최근에 널리 사용되고 있다. 현재까지 개발된 여러 가지 천자침은 공통적으로 타격에 의하여 신체에 인입되므로 비록 국소마취 한 상태의 환자일지라도 심한 통증을 느끼게 되며 천자침과 척추체 사이에 각극이 커져서 골시멘트가 유출되고 모세혈관을 타고 인체에 퍼지는 부작용이 따른다. 또한 척추체의 다공층에 골시멘트가 주입될 공간을 확장하는 수단은 풍선확장법 이외에는 달리 없다는 것이다.In general, in the treatment of spinal compression fracture, the guide pin is first blown to open or puncture a passage through which a puncture needle can be introduced into the muscle and the vertebral body, and a puncture needle is inserted therein to inject a bone cement into the puncture needle using a syringe or a gun. do. However, it is widely used recently to use a balloon to expand the space in which bone cement is to be injected. The various puncture needles developed to date are commonly introduced into the body by hitting, so even in patients with local anesthesia, the patient feels severe pain.At the angle between the puncture needle and the vertebral body, the bone cement leaks out and the capillaries spread to the human body. There are side effects. In addition, there is no means for expanding the space where bone cement is to be injected into the porous layer of the vertebral body other than the balloon dilation method.
본 고안은 이러한 점에 착안하여 개발된 것으로서 천자침이 척추체에 인입될 때 물리적 타격을 가하지 아니하면서도 안전하게 시술할 수 있고, 천자침과 척추체 사이에 간극이 발생하지 않고 밀착된 상태를 유지할 수 있는 구조를 기술적 과제로 하고 있다. 아울러 골시멘트가 주입되는 공간을 손쉽게 확장할 수 있고 1회용품인 천자침을 재사용할 수 없는 구조로 개발함을 또 다른 기술적 과제로 삼는다.The present invention was developed in view of this point, and when the puncture needle is introduced into the vertebral body, it can be safely performed without physical impact, and there is no structure between the puncture needle and the vertebral body without maintaining a gap. It is a problem. In addition, it is another technical task to develop a structure that can easily expand the space in which bone cement is injected, and can not reuse the disposable needle puncture.

본 고안의 가이드핀(1)과 천자침본체(2), 푸셔(13), 다일레이터(14) 그리고 주사기(15)를 한 세트로 하고 있다. 가이드핀(1)은 천자침 본체(2)와 직경의 크기가 대등하다. 가이드핀(1) 내부에 주입로(8)가 형성된 천자침 본체(2) 그리고 푸셔(13), 주사기(15)는 일반적으로 공통되는 구성이다. 본 고안의 특징은 천자침본체(2)와 다일레이터(14)의 구성과 서로의 유기적 관련성에 있다.The guide pin 1, the puncture needle body 2, the pusher 13, the dilater 14, and the syringe 15 of the present invention are set as one set. The guide pin 1 is equal in size to the puncture needle body 2. The puncture needle body 2 and the pusher 13 and the syringe 15 in which the injection passage 8 is formed in the guide pin 1 are generally in common configuration. A feature of the present invention lies in the configuration of the puncture body 2 and the dilatator 14 and their organic relationship with each other.
본 고안의 구성을 상세히 설명하면 다음과 같다.Referring to the configuration of the subject innovation in detail as follows.
내부에 주입로(8)가 형성된 통상의 천자침 본체(2)에 있어서, 본체(2)의 첨단에는 드릴부(3)를 그리고, 그 둘레에는 나선부(4)를 형성하는 한편, 본체(2)의 나선부(4) 일측에 상당한 길이는 가진 측면배출공(5)을 형성하여 첨단부가 만곡된 다일레이터(10)가 통과할 수 있게 한 구성을 특징으로 한다.In the conventional puncture needle body 2 having an injection path 8 formed therein, a drill portion 3 is formed at the tip of the body 2, and a spiral portion 4 is formed at the periphery thereof. The side of the spiral portion (4) of the side is formed with a side discharge hole (5) having a considerable length is characterized by a configuration that allows the tip of the curved diopter (10) to pass through.
또한 본체(2)의 첨단 내부에 후육부를 이루는 팁관(7)을 용접한 구성으로 재사용을 방지하는 수단으로 삼을 수 있다.이와 같이 구성된 본 고안은 먼저 환자의 등(16)에 비스듬히 가이드핀(1)을 박아 근육에 통로를 형성한 후 본체(2)를 역회전 시키면서 인입시킨다. 이 때 본체(2)에 푸셔(13)를 결합시킨 상태로 인입시키기도한다. 그 까닭은 인입이 보다 용이할 뿐만 아니라 전면배출공(6)을 통하여 신체의 조직이 밀려드는 것을 방지하기 위함이다. 또한 본체(2)를 약간 역회전시키는 것은 그릴부(3)나 나선부(4)가 근육을 손상시키지 않도록 한 배려이다. 도 4와 같이 드릴부(3)가 척추체(17)에 닿으면 본체(2)의 핸들(9)을 돌려 드릴부(3)가 척추체(17)를 깍으며 진입하고 척추체(17)의 분말은 전면배출공(6)으로 역류되어 측면배출공(5)으로 인도된다.In addition, the tip tube 7 forming the thick portion inside the tip of the main body 2 can be used as a means of preventing reuse by the configuration. (1) drive the muscles to form a passage, and then the body (2) is introduced while rotating in reverse. At this time, the main body 2 may be pulled in with the pusher 13 coupled thereto. The reason for this is not only to facilitate the introduction, but also to prevent the body tissue from being pushed through the front discharge hole 6. Further, slightly rotating the main body 2 is considered so that the grill portion 3 and the spiral portion 4 do not damage the muscles. As shown in FIG. 4, when the drill part 3 contacts the vertebral body 17, the handle 9 of the main body 2 is turned to enter the drill part 3 while cutting the vertebral body 17, and the powder of the vertebral body 17 is It flows back to the front discharge hole 6 and is led to the side discharge hole 5.
본체(2)가 의도한 위치에 인입되면 주입구(11)로 푸셔(13)를 넣어 주입로(8)에 들어온 뼈분말을 밀어낸다. 이것은 골시멘트가 원활하게 주입되도록 하기 위한 것이다. 다시 주입구(11)로 다일레이터(14)를 투입하여 만곡된 첨단부가 측면배출공(5)을 통하여 척추체의 다공층에 인출되게 한다. 다일레이터(14)를 전지, 후퇴, 회전시키면 다공층에 공간이 형성된다.When the main body 2 is drawn in the intended position, the pusher 13 is inserted into the injection hole 11 to push the bone powder into the injection path 8. This is to allow the bone cement to be smoothly injected. The injector 11 is fed back into the injector 11 so that the curved tip portion is drawn out to the porous layer of the vertebral body through the side discharge hole 5. The battery is retracted, rotated, and rotated to form a space in the porous layer.
마지막으로 알맞은 점도로 희석된 골시멘트를 주입구(11)로 주사한다. 주사기(15)를 본체(2)의 결합부(10)에 나사결합하여 골시멘트를 주사하면 골시멘트(18)는 도 5에서 보는 바와 같이 전면배출공(6)과 측면배출공(5)을 통하여 골다공층에 형성된 공간에 층입된다. 층입된 골시멘트는 5 내지 13분이면 응결되고 환자는 시술 당일 퇴원할 수 있게 된다.Finally, the bone cement diluted to a suitable viscosity is injected into the inlet (11). When the syringe 15 is screwed into the coupling portion 10 of the main body 2 to scan the bone cement, the bone cement 18 has a front discharge hole 6 and a side discharge hole 5 as shown in FIG. 5. It enters the space formed in the bone porous layer through. The laminated bone cement condenses in 5 to 13 minutes and the patient can be discharged on the day of the procedure.
이상 살펴본 바와 같이, 본 고안은 천자침에 드릴부와 나선부를 형성하여 회전에 의하여 척추체에 인입되므로 타격에 의한 통증 유발을 방지할 수 있으며, 다일레이터를 측면배출공으로 인출시켜 골다공층에 효과적으로 공간부를 확보할 수있는 것이 두드러진 특징이다.As described above, the present invention forms a drill part and a spiral part in the puncture needle to be introduced into the vertebral body by rotation, thereby preventing the pain caused by the blow, and drawing the dillator to the side discharge hole to effectively secure the space in the bone porous layer. It is a prominent feature that can be done.
또한 선택사항이지만 본체의 첨단부 내경에 팁관을 용접하여 골시멘트가 측면배출공으로 다량 배출되게 함과 동시에 사용 후 쉽게 전면배출공이 골시멘트에 의하여 봉쇄되게 하여 재사용이 불가능하게 하는 효과가 있다.In addition, it is optional, but the tip tube is welded to the inner diameter of the tip of the body to allow the bone cement to be discharged to the side discharge hole in a large amount, and at the same time, the front discharge hole can be easily blocked by the bone cement so that it cannot be reused.
