本实用新型属于医疗器械技术领域，具体涉及一种锁紧扣能松开解锁的医用线缆。The utility model belongs to the technical field of medical devices, in particular to a medical cable whose locking buckle can be released and unlocked.
背景技术Background technique
在骨科手术中，线缆捆扎技术通常用于创伤外科包括假体周围骨折、股骨骨折、尺骨鹰嘴骨折、髌骨骨折、肱骨和踝关节骨折，肩锁关节脱位、髋臼骨折、全关节置换、开放复位中的临时固定以及重建大转子等手术的捆绑。为此人们提出了诸多有关医用线缆的技术方案，如公告号：CN203647457“一种医用捆扎带系统”、CN201052176“一种接骨线缆”等。从以上二个专利的技术方案可以看出，现有的“医用线缆”的技术方案都设有锁扣结构，前者的锁扣结构称之为锁扣，后者的锁扣结构称之为夹紧扣，但它们存在的弊是不能根据手术的需要从新松开解锁；另外，前者的锁扣结构复杂，而后者的夹紧扣要通过外界的器械来实现线缆的最终锁紧，这难免会增加医生的操作难度并使得手术的时间延长。In orthopedic surgery, cable binding techniques are commonly used in trauma surgery including periprosthetic fractures, femoral fractures, olecranon fractures, patella fractures, humeral and ankle fractures, acromioclavicular joint dislocations, acetabular fractures, total joint replacements, Temporary fixation in open reduction and tying for operations such as reconstruction of the greater trochanter. For this reason, people have proposed many technical solutions related to medical cables, such as announcement numbers: CN203647457 "a kind of medical strapping system", CN201052176 "a kind of bone-synthetic cable" and the like. From the technical solutions of the above two patents, it can be seen that the existing technical solutions of "medical cables" are all equipped with a locking structure. The former locking structure is called a locking structure, and the latter locking structure is called a Clamping buckles, but they have the disadvantage that they cannot be loosened and unlocked according to the needs of the operation; in addition, the former has a complex structure, while the latter's clamping buckle needs to be finally locked by external instruments. It will inevitably increase the difficulty of the doctor's operation and prolong the operation time.

上述的发明目的是通过以下技术方案实现的，一种锁紧扣能松开解锁的医用线缆，包括线缆，其要点在于线缆后端制有球头，线缆设有斜齿A；一锁紧扣与线缆匹配锁紧线缆；所述的锁紧扣是在一锁紧扣体上设有线缆能穿过的圆孔A和圆孔B，圆孔A设有与线缆斜齿A倾斜方向相反但互相匹配的斜齿B；线缆后端的球头直径大于锁紧扣体圆孔B的直径；锁扣时，线缆头部从锁紧扣体的圆孔B穿入至圆孔B抵住线缆后端的球头，再将线缆穿入圆孔A，并根据手术需要确定线缆穿过圆孔A的长度，此时线缆的斜齿A与锁紧扣体的圆孔A的斜齿B匹配锁紧。The purpose of the above invention is achieved through the following technical solutions, a medical cable whose locking buckle can be released and unlocked, including the cable, the main point of which is that the rear end of the cable is made with a ball head, and the cable is provided with helical teeth A; A locking buckle matches the cable to lock the cable; the locking buckle is provided with a round hole A and a round hole B through which the cable can pass, and the round hole A is provided with a wire The inclined direction of the cable helical tooth A is opposite but the helical tooth B matches each other; the diameter of the ball head at the rear end of the cable is larger than the diameter of the round hole B of the locking buckle body; when locking, the cable head passes through the round hole B of the locking buckle body Penetrate to the round hole B to resist the ball head of the rear end of the cable, then pass the cable into the round hole A, and determine the length of the cable passing through the round hole A according to the needs of the operation. At this time, the helical teeth A of the cable and the lock The helical tooth B of the round hole A of the fastening body matches and locks.
作为优选，锁紧扣体的圆孔A的斜齿B设在圆孔A的端口，并相对圆孔A能上下摆动，而在锁紧扣体圆孔A的斜齿B下方设有一楔形孔，楔形孔中匹配有楔；需要松开解锁时，只需将楔从楔形孔中拔出，此时锁紧扣体的圆孔A的斜齿B下摆，与线缆的斜齿A脱离，线缆即可从锁紧扣体的圆孔A中拉出。As a preference, the helical tooth B of the round hole A of the locking button body is arranged at the port of the round hole A, and can swing up and down relative to the round hole A, and a wedge-shaped hole is provided under the helical tooth B of the round hole A of the locking button body , a wedge is matched in the wedge-shaped hole; when it needs to be released and unlocked, just pull out the wedge from the wedge-shaped hole, and at this time, the hem of the helical tooth B of the round hole A of the locking button body is separated from the helical tooth A of the cable. The cable can be pulled out from the round hole A of the locking button body.
本实用新型与现有技术相比，它不但结构简单，无须外界工具辅助自身即可锁紧，便于医生操作和节省手术时间；而且能根据手术的需要可从新松开解锁，具体操作只需将楔从楔形孔中拔出，此时锁紧扣体的圆孔A的斜齿B下摆，与线缆的斜齿A脱离，线缆即可从锁紧扣体的圆孔A中拉出。Compared with the prior art, the utility model not only has a simple structure, but can be locked without the assistance of external tools, which is convenient for doctors to operate and saves operation time; moreover, it can be loosened and unlocked according to the needs of the operation. The wedge is pulled out from the wedge-shaped hole. At this time, the hem of the helical tooth B of the round hole A of the locking button body is separated from the helical tooth A of the cable, and the cable can be pulled out of the round hole A of the locking button body.
