골시멘트 혼합 주입 기구{MIXING AND INJECTION TOOL OF BONE CEMENT}Bone Cement Mixing Injection Device {MIXING AND INJECTION TOOL OF BONE CEMENT}

본 발명은 골시멘트 혼합 주입 기구에 관한 것으로서, 상세하게는 척추관절과 인공관절을 견고하게 고정하기 위한 일종의 합성수지인 골시멘트를 혼합하고 인체에 주입하기 위한 수술도구에 관한 것이다.
The present invention relates to a bone cement mixing injection device, and more particularly, to a surgical tool for mixing bone cement, which is a kind of synthetic resin for firmly fixing a vertebral joint and an artificial joint, and injecting it into a human body.

골시멘트(Bone Cement) 주입술은 뼈와 성질이 유사한 일종의 시멘트로 인공뼈를 만들기 위한 수술의 일종이다. 골다공증이나 악성 종양에 의한 척추의 압박골절, 외상 후의 척추체 이탈, 다발성 골수종, 척추체 혈관종 등에 적용되는 것으로, 주저앉은 뼈에 골시멘트를 주입시켜 단단하게 하는 것이다.Bone Cement Injection is a kind of surgery to make artificial bones with a kind of cement that is similar in properties to bones. It is applied to compressive fractures of the spine due to osteoporosis or malignant tumors, vertebral body detachment after trauma, multiple myeloma, vertebral hemangioma, etc., by injecting bone cement into stagnant bone to harden it.

이를 위해서 주사기로 골시멘트를 주입하게 되고, 주입 후 일정 시간 후 골시멘트가 굳음으로써 수술이 완료된다.To this end, the bone cement is injected into the syringe, and the surgery is completed by the bone cement hardening after a certain time after the injection.

일반적으로 골시멘트는 분말파우더에 액상 재료를 혼합하여 일정 정도의 점성을 유지시킨 상태로 인체에 주입하게 되는데, 이를 혼합하는 것은 불활성 물질로 만들어진 혼합용기에 투입하여 사람이 직접 혼합을 하게 되고, 혼합 후 보통의 주사기에 주입하여 수술을 통해서 인체의 적정 위치에 골시멘트를 주입하게 된다.In general, bone cement is injected into the human body in a state of maintaining a certain viscosity by mixing the liquid material in the powder powder, the mixing is put into a mixing container made of an inert material and the human is directly mixed, mixed After the injection into the usual syringe is injected bone cement in the proper position of the human body through surgery.

즉, 이와 같이 골시멘트는 의료인이 직접 용기 내에서 혼합한 후 사용하게 되는데, 골시멘트는 그 화학적 특성으로 인해 심한 냄새를 발생하게 되어 의료인이 직접적으로 이를 흡입하면서 작업을 할 수밖에 없는 실정인데, 골시멘트의 특유의 냄새와 휘발성분 때문에 이를 혼합 작업하는 의료인은 불쾌감을 느끼면서 작업을 할 수밖에 없으며, 그 냄새는 매우 강하여 이를 계속적으로 맡다보면 심지어 쓰러지는 경우도 간혹 발생하게 되는 등으로 인체에 유해할 수 있으나, 현재까지는 이러한 직접적인 방법에 의해서만 작업을 하고 있는 실정이었다.
In other words, the bone cement is used after the medical person directly mixes in the container, and the bone cement has a bad smell due to its chemical properties, and the medical person has to work directly while inhaling it. Due to the peculiar smell and volatile content of cement, medical workers who work with it are forced to work unpleasantly, and the smell is very strong.

It is to be injected into.

피스톤몸체(130)는 믹싱시나 주입시에 물질이 새는 것을 방지하고, 마찰을 방지하기 위해 하부에는 패킹(131)과 결합을 하게 되고, 상부에는 끼움돌기(132)가 형성되어 상부 바디(120)의 내측에 형성되는 끼움홈(124)에 끼워져 결합되도록 구성된다.The piston body 130 is prevented from leaking material during mixing or injection, and is coupled to the packing 131 in the lower part to prevent the friction, the upper fitting body 132 is formed on the upper body 120 It is configured to be fitted into the fitting groove 124 formed in the inner side of the.

상부 바디(120)는 이 같이 하부 바디(110)와의 결합과 피스톤몸체(130)와의 결합을 위해 내측이 이중적인 구조로 형성되어, 상부 바디(120)의 제1 내측(O)으로 하부 바디(110)가 결합되고, 관통홀(123)에 의해 형성된 제2 내측(I)에 끼움홈(124)과 주입부재(300)와 맞물리는 나사산(125)이 별도 형성된 구조를 가진다.
The upper body 120 is formed in a double-sided structure for the coupling with the lower body 110 and the piston body 130 in this way, the lower body 110 as a first inner side (O) of the upper body 120 ) Is coupled to each other, and the fitting groove 124 and the screw thread 125 engaged with the injection member 300 are separately formed in the second inner side I formed by the through hole 123.

다음으로, 믹싱부재(200)는 하부 바디(110) 내의 내포물을 혼합하기 위한 부재로서, 믹싱판(210), 믹싱로드(220) 및 믹싱손잡이(230)로 구성된다.Next, the mixing member 200 is a member for mixing the inclusions in the lower body 110, and is composed of a mixing plate 210, mixing rod 220 and mixing knob 230.

믹싱판(210)은 하부 바디(110)의 내부공간에 위치되어 내부공간에 주입된 골시멘트에 압력을 가하여 골시멘트가 고르게 혼합될 수 있게 하기 위한 구성으로, 내부공간 보다는 작은 직경의 원판 형상이며, 분할되어 뚤려진 형상을 가져 혼합이 잘 이루어지도록 구성된다.The mixing plate 210 is positioned in the inner space of the lower body 110 to apply pressure to the bone cement injected into the inner space so that the bone cement can be mixed evenly, and has a disk shape having a smaller diameter than the inner space. It has a divided and bent shape so that mixing is performed well.

믹싱로드(220)는 믹싱판(210)으로부터 이어져서 일정한 길이를 가짐으로써 상부 바디(120)의 관통홀(123)을 통과하여 외부로 드러나며, 믹싱로드(220)에 결합되는 믹싱손잡이(230)에 의해 하부 바디(110)의 내부공간을 왕복운동할 수 있게 마련된다.The mixing rod 220 extends from the mixing plate 210 and is exposed to the outside through the through hole 123 of the upper body 120 by having a predetermined length, and the mixing handle 230 coupled to the mixing rod 220. It is provided to reciprocate the inner space of the lower body 110 by.

이러한 믹싱판(210) 및 믹싱로드(220)는 상부 바디(120) 및 피스톤몸체(130)보다 먼저 하부 바디(110)에 삽입되고, 이 후 피스톤몸체(130)가 결합된 상부 바디(120)를 하부 바디(110)에 결합시킨 후 믹싱손잡이(230)를 믹싱로드(220)에 결합시키게 된다.The mixing plate 210 and the mixing rod 220 are inserted into the lower body 110 before the upper body 120 and the piston body 130, and then the upper body 120 to which the piston body 130 is coupled. After coupling to the lower body 110, the mixing knob 230 is coupled to the mixing rod 220.

이의 결합을 위해 믹싱로드(220)의 후단에는 결합구(221)가 형성되고, 결합구(221)는 믹싱손잡이(230)의 결합홈(231)에 끼워져 결합될 수 있도록 구성되고, 끼워진 결합구(221)를 고정구((240)가 벌리면서 삽입되어 고정을 견고히 한다.
A coupling sphere 221 is formed at the rear end of the mixing rod 220 for coupling thereof, and the coupling sphere 221 is configured to be coupled to the coupling groove 231 of the mixing handle 230 and is fitted with a coupling sphere. 221 is a fastener (240) is inserted while opening to secure the fixing.

이상과 같이 구성됨에 의해, 하부 바디(110)의 내부공간에 주입된 골시멘트를 믹싱부재(200)를 작업자가 믹싱손잡이(230)를 이용하여 도4 및 도5와 같이 압력을 가함으로써 골시멘트가 고루 혼합되도록 하며, 혼합시에는 마개(113)를 주입홀(111)에 끼워 밀폐시킨 후 혼합시킨다.
By the above configuration, the bone cement injected into the inner space of the lower body 110 by applying the pressure to the mixing member 200 as shown in Figures 4 and 5 by the operator using the mixing knob 230. To be evenly mixed, when mixing the stopper 113 is inserted into the injection hole 111 and sealed after mixing.

다음으로, 본 발명에 따른 골시멘트 혼합 주입 기구는 주입부재(300)를 더 포함하여 구성된다.Next, the bone cement mixing injection apparatus according to the present invention further comprises an injection member 300.

주입부재(300)는 내부가 뚤려 있어 믹싱로드(220)가 관통될 수 있게 마련되고, 혼합 작업을 마친 후 믹싱손잡이(230)를 인위적으로 제거한 후 관통시켜서 주입작업을 수행하게 된다.The injection member 300 is provided to allow the mixing rod 220 to penetrate the inside thereof, and after the mixing operation is completed, the mixing handle 230 is artificially removed and then penetrated to perform the injection operation.

주입로드(310)에는 외측에 나사산(311)이 형성되는데, 이 나사산(311)이 상부 바디(120)의 제2 내측(I)의 나사산(125)에 대응되게 된다.The injection rod 310 has a thread 311 formed on the outside thereof, and the thread 311 corresponds to the thread 125 of the second inner side I of the upper body 120.

즉, 믹싱부재(200)의 믹싱손잡이(230)를 인위적으로 제거한 후, 주입로드(310) 내부로 믹싱로드(220)가 관통되며 주입로드(310)는 상부 바디(120)의 관통홀(123)을 통해서 관통되게 한 후 핸들(320)을 조작함에 따라, 주입로드(310)가 상부 바디(120)의 제2 내측(I) 나사산(125)에 맞물려 전진함으로써 주입로드(310)가 피스톤몸체(130)를 밀어서 하부 바디(110) 내부의 골시멘트가 주입홀(111)을 통해 주입되도록 작동되는 것이다.
That is, after artificially removing the mixing knob 230 of the mixing member 200, the mixing rod 220 penetrates into the injection rod 310 and the injection rod 310 passes through the through hole 123 of the upper body 120. As the handle 320 is manipulated after passing through the rod, the injection rod 310 is engaged with the second inner (I) thread 125 of the upper body 120 to move forward so that the injection rod 310 is moved by the piston body. By pushing 130, bone cement inside the lower body 110 is operated to be injected through the injection hole 111.

마지막으로, 사용에 따라 하나의 골시멘트 혼합 주입 기구로부터 다른 기구로 내용물을 옮기는 작업이 가능하도록 본 발명에 따른 골시멘트 혼합 주입 기구는 연결부재(400)를 더 포함할 수 있다.Finally, the bone cement mixing infusion apparatus according to the present invention may further include a connection member 400 to enable the operation of moving the contents from one bone cement mixing infusion apparatus to another in accordance with use.

연결부재(400)는 마개(113)가 이중으로 구성되되, 내부가 관통된 형상으로 마련되어, 두 기구를 연결부재(400)를 통해 연결시킨 후 하나의 기구에서 주입부재(300)에 의해 주입하는 경우 연결된 다른 기구로 내용물을 쉽게 옮길 수 있게 된다. 그리하여, 필요에 따라 내용물을 이동시키거나 분량에 따른 배분이 가능해진다.
The connecting member 400 has a double stopper 113 is provided in a shape that is penetrated through the inside, and connected by the injection member 300 in one device after connecting the two devices through the connection member 400 In this case, the contents can be easily transferred to other connected devices. Thus, the contents can be moved or distributed according to the amount as necessary.
