技术领域technical field
本发明是有关于一种骨水泥注射器，尤指可作为骨水泥的注射而使用的骨水泥注射器。The invention relates to a bone cement injector, especially a bone cement injector which can be used for injection of bone cement.
背景技术Background technique
骨水泥常用于人工膝、髋关节置换及脊椎椎体成形等多项骨科手术，而该脊椎椎体成形的手术广泛运用于骨质疏松而引发脊椎压迫性骨折变形，或因其它转移性骨肿瘤引起的骨骼破坏与疼痛，因此骨水泥于注射时，必须配合注入器的使用，才可顺利将骨水泥注射进入手术患者的骨骼内。Bone cement is often used in many orthopedic surgeries such as artificial knee, hip replacement, and vertebroplasty, and this vertebroplasty operation is widely used in vertebral compression fracture deformation caused by osteoporosis, or due to other metastatic bone tumors. Bone destruction and pain caused by bone cement injection must be used in conjunction with the injector, so that the bone cement can be successfully injected into the bone of the surgical patient.
而目前，虽有中国台湾新型第M421803号的“骨水泥注射器之构造”、第M430285号的“骨水泥注射推进器套组”及第M346407号的“骨水泥注射器之辅助压挤装置”等各前案专利皆揭示可将骨水泥注射进入手术患者的骨骼内，但其结构设计明显较为复杂；此外，前揭各前案专利于施行注射时，是以螺杆配合注射，再以旋转的方式将骨水泥推入骨骼内，但由于骨骼内存有血水与空气，因此手术医师于施行注射时，即因血水与空气存在于骨骼的密闭空间，而须施以更大的外推力才可顺利注射，导致注射不易操作且速度过于缓慢，如此不但增加手术医师于手术进行过程中的压力，更使手术患者有感染或形成肺栓塞的风险。And at present, although there are "the structure of the bone cement syringe" of No. M421803 of Taiwan, China, the "bone cement injection thruster set" of the No. M430285 and the "auxiliary extrusion device of the bone cement syringe" of the No. M346407, etc. The previous patents all disclose that the bone cement can be injected into the bone of the surgical patient, but the structural design is obviously more complicated; in addition, when the previous patents are injected, the screw is used to cooperate with the injection, and then the cement is rotated to The bone cement is pushed into the bone, but because the bone contains blood, water and air, the surgeon must apply a greater external thrust to inject smoothly because the blood, water and air exist in the confined space of the bone when performing the injection. As a result, the injection is difficult to operate and the speed is too slow, which not only increases the pressure on the surgeon during the operation, but also puts the surgical patient at risk of infection or pulmonary embolism.

具体实施方式detailed description
请参阅「图1、图2及图3」所示，分别为本发明的立体外观示意图、本发明的立体分解示意图及本发明的剖面操作状态示意图。如图所示：本发明一种骨水泥注射器，其至少由一外筒1、一注射单元2及一抵推单元3所构成，其中该外筒1与该注射单元2为金属材质、非金属材质或可透光材质。Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are respectively the three-dimensional appearance schematic diagram of the present invention, the three-dimensional exploded schematic diagram of the present invention, and the cross-sectional operational state schematic diagram of the present invention. As shown in the figure: a bone cement syringe of the present invention is at least composed of an outer cylinder 1, an injection unit 2 and a thrust unit 3, wherein the outer cylinder 1 and the injection unit 2 are made of metal, non-metal material or translucent material.
上述该外筒1具有一剖槽11，而该外筒1的顶端设有一缓冲部12，且该外筒1的表面上设有刻度区13。The above-mentioned outer cylinder 1 has a slot 11 , and the top of the outer cylinder 1 is provided with a buffer portion 12 , and the surface of the outer cylinder 1 is provided with a scale area 13 .
该注射单元2活动设于外筒1内，且该注射单元2包含有一具有第一中空区211的内管21、及一以适当距离设置于内管21外缘的外管22，使该内管21与该外管22之间具有一第二中空区221，并于该外管22上设有一位于剖槽11内且连通第二中空区221的导管23。The injection unit 2 is movably arranged in the outer cylinder 1, and the injection unit 2 includes an inner tube 21 having a first hollow area 211, and an outer tube 22 arranged on the outer edge of the inner tube 21 at an appropriate distance, so that the inner tube 21 There is a second hollow area 221 between the tube 21 and the outer tube 22 , and a conduit 23 located in the slot 11 and connected to the second hollow area 221 is provided on the outer tube 22 .
该抵推单元3活动设于第一中空区211内且抵靠于外筒1的底端，其中该抵推单元3包含有一活动设于第一中空区211内的推杆31、及一设于推杆31一端且抵靠于外筒1底端的座体32。如是，借助上述技术特征组合成一全新的骨水泥注射器。The pushing unit 3 is movably arranged in the first hollow area 211 and abuts against the bottom end of the outer cylinder 1, wherein the pushing unit 3 includes a push rod 31 movably arranged in the first hollow area 211, and a set One end of the push rod 31 leans against the base 32 at the bottom of the outer tube 1 . If so, a brand-new bone cement injector is combined by means of the above-mentioned technical features.
当本发明于使用时，可将骨水泥4填充于内管21的第一中空区211内，并以空压机的管路(图未示)与导管23连接，而后再以外筒1的缓冲部12与注射单元2的一端对应插入欲注射骨水泥4的骨骼5内，并向座体32的方向拉动导管23，令注射单元2向后移动而使骨水泥4借助推杆31作动而向第一中空区211的一端排出，而当骨水泥4自第一中空区211的一端排出时，亦同时启动空压机并配合导管23，将骨骼5内的血水与空气自第二中空区221吸出，当血水与空气被吸出时，则使骨骼5的内部与外部产生压力差(意指骨骼5内部略成真空状)，导致骨水泥4因出现压力差而被吸入骨骼5内，因此操作骨水泥4的注射相对容易且省力。When the present invention is in use, the bone cement 4 can be filled in the first hollow area 211 of the inner tube 21, and the pipeline (not shown) of the air compressor is connected to the catheter 23, and then the buffer of the outer cylinder 1 The part 12 and one end of the injection unit 2 are correspondingly inserted into the bone 5 to be injected with the bone cement 4, and the catheter 23 is pulled toward the seat body 32, so that the injection unit 2 moves backward so that the bone cement 4 is actuated by the push rod 31. It is discharged to one end of the first hollow area 211, and when the bone cement 4 is discharged from one end of the first hollow area 211, the air compressor is also started at the same time and the catheter 23 is used to discharge the blood, water and air in the bone 5 from the second hollow area. 221 suction, when the blood and air are sucked out, a pressure difference will be generated between the inside and outside of the bone 5 (meaning that the inside of the bone 5 is slightly vacuum-like), causing the bone cement 4 to be sucked into the bone 5 due to the pressure difference, so The injection of bone cement 4 is relatively easy and labor-saving.
此外，于手术中进行上述的注射过程时，可利用外筒1上的刻度区13而控制骨水泥4施打的用量，以避免施打用量过多或不足。In addition, when the above-mentioned injection process is performed during the operation, the amount of bone cement 4 injected can be controlled by using the scale area 13 on the outer cylinder 1, so as to avoid excessive or insufficient injection amount.
综上所述，本发明骨水泥注射器有效改进现有缺失，可将骨水泥灌设于第一中空区内，并拉动注射单元使抵推单元将骨水泥注射进入手术患者的骨骼内，且于注入时一并利用空压机配合导管而将骨骼内的血水与空气自第二中空区吸出，当血水与空气被吸出时，则同时因压力差而使骨水泥被吸入骨骼内，本发明因此结构设计简单、容易操作且省力，并达到快速注射的功效，确实使本发明更进步、实用且符合手术医师的需求。To sum up, the bone cement injector of the present invention effectively improves the existing defect, and the bone cement can be poured into the first hollow area, and the injection unit is pulled to make the pushing unit inject the bone cement into the bone of the surgical patient, and then When injecting, use the air compressor together with the catheter to suck out the blood and air in the bone from the second hollow area. When the blood and air are sucked out, the bone cement will be sucked into the bone due to the pressure difference at the same time. Therefore, the present invention The structural design is simple, easy to operate and labor-saving, and achieves the effect of rapid injection, which indeed makes the invention more progressive, practical and meets the needs of surgeons.
