의료용 스크류{A screw for medical care}A screw for medical care

본 발명은 의료용 스크류(screw)에 관한 것으로 특히 뼈 골절에 의한 접합수술에서 절개 이완된 뼈를 밀착 고정하기 위한 스크류머리에 와이어 체결공을 구성한 장고형 머리로 이루어지는 의료용 스크류에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical screw, and more particularly to a medical screw consisting of a janggo head comprising a wire fastening hole in a screw head for tightly fixing a bone that has been loosened in a joint operation due to bone fracture.

주지하는 바와 같이 골절(fracture, 骨折)은 외력 작용(충격등)이 강하여 뼈가 이단(離斷)된 상태로 이러한 이단은 외력과 함께 최근에 급속히 발전된 의료행위와 미용 목적에서 많이 발생되고 있다.As is well known, the fracture (fracture) has a strong external force action (impact, etc.), so that the bone is heresy, and this heresy is often generated in recent years with the rapid development of medical activities and cosmetic purposes.

즉, 충격으로 골절된 뼈를 접착하기 위한 수술과 또는 치료목적의 수술에서 뼈 내부를 치료할 때에 외부의 뼈를 절개, 이탈하고 치료를 마친 다음 다시 절개된 뼈를 밀착 고정하는 수술이 자주 시행되고 있다.In other words, surgery to bond bones fractured by impact, or surgery to treat the inside of a bone in a surgical purpose surgery is frequently performed to incise, detach the external bone, and to fix and fix the bone incision after the treatment is finished. .

이 때에 절개된 뼈를 밀착시켜 견고히 고정하기 위하여 접합부의 절개선을 기점으로 양측에 체결공을 뚫은 체결부재를 이용하게 된다.In this case, in order to securely fix the cut bones tightly, a fastening member having a fastening hole drilled at both sides of the joint line is used.

예컨데 상기 절개선 양측 뼈 표면에 체결부재(죔쇠; fastenerS)의 체결공 위치와 일체되게 드릴로 1차 체결 스크류공을 형성하고 이에 상기 체결부재를 적층한 상태에서 상기 체결공을 관통하는 스크류로 체결스크류공에 체결함으로 절개된 뼈를 압인함과 함께 고정함으로 골절된 뼈를 안정되게 고정하게 되는 것이다.For example, a primary fastening screw hole is formed on a surface of the bone on both sides of the incision line with a fastening hole of a fastening member (fastener; fasteners), and is fastened by a screw penetrating the fastening hole in a state in which the fastening member is stacked. By fastening the bones cut by fastening to the screw hole and fixing the fractured bones will be stable.

이와 같이 접합할 뼈표면에 스크류공을 천공하여 체결부재를 맞춤한 상태에서 체결스크류로 체결하게 됨으로서 체결작업이 난이하고 특히 스크류공의 형성 및 거리조절에서 정밀성이 결여됨으로서 체결부재의 양 체결공과 스크류공이 일치되지 않는 폐단으로 절개부의 밀착성이 결여됨으로 치유 효과에 나쁜 영향을 끼치게 되고 작업이 매우 난이한 문제점을 가지고 있는 것이다.In this way, by drilling a screw hole on the bone surface to be joined and fastening it with the fastening screw in the state of fitting the fastening member, the fastening work is difficult, and in particular, the lack of precision in the formation and distance control of the screw hole, both fastening holes and the screw of the fastening member Due to the inconsistent closure of the ball, the lack of adhesion to the incision adversely affects the healing effect and the task is very difficult.

상기한 수술에서 스크류의 체결드라이버와 스크류의 이탈을 방지하기 위하여 드라이버 끝단부를 자화(자력을 주입)시키고 또는 상기 체결부재의 크기를 다양한 크기로 구성시켜 크기에 따른 부재를 이용하도록 하고 있으나 이러한 구성은 단순 정밀도를 유지시키는 정도에 있어 미세조절 및 용이한 수술작업을 할 수 있는 효과가 저조한 단점을 가지고 있는 것이다.In the above operation, in order to prevent detachment of the screw driver and the screw of the screw, the end of the driver is magnetized (injected with magnetic force) or the size of the fastening member is configured in various sizes so as to use a member according to the size. In the degree of maintaining simple precision, the effect of fine adjustment and easy surgical operation has a disadvantage.

본 발명은 상기한 종래의 단점을 개선하기 위하여 안출된 것으로 특히 체결스크류의 끝단에 탭끝(tap)을 형성시켜 스크류공을 별도로 형성하지 않고도 단단한 뼈에 스크류를 직접 체결할 수 있도록 함과,The present invention has been made in order to improve the above-mentioned disadvantages, in particular to form a tap end (tap) at the end of the fastening screw to directly screw to a solid bone without forming a screw ball, and

상기 스크류머리를 상,하접시 내로 일정크기의 머리몸체를 형성한 장고형머리로 구성함과 함께 상기 머리몸체에 와이어체결공을 형성하여 양 스크류의 와이어체결공에 체결된 와이어를 당김 및 고정할 수 있도록 함으로서 자유로운 거리에서의 체결과 당김 압축으로 인한 절개부의 밀착, 고정효과를 증대시켜 빠른 치유를 유도하도록 한 의료용 스크류를 제공하기 위한 것이다.The screw head is composed of a high-density head which has a certain size of the head body into the upper and lower plates, and a wire fastening hole is formed in the head body to pull and fix the wire fastened to the wire fastening holes of both screws. It is to provide a medical screw that induces rapid healing by increasing the adhesion and fixing effect of the incision due to fastening and pulling compression at a free distance.
