需要说明的是，在对患者进行滑膜活检取样检测时，可以使用本装置来辅助医护人员对患者进行取样，首先将穿刺针芯3插入中空穿刺针1内，使得空心刃口2和实心刃口31处于同一水平面上，之后对患者取样部位进行穿刺处理，打开组织开口，完成后将穿刺针芯3向右拔出，将中空穿刺针1留在患者体内，紧接着将前端封闭式中空取样针4插入中空穿刺针1内部。It should be noted that when performing synovial biopsy sampling and testing on patients, this device can be used to assist medical staff in sampling the patient. First, insert the puncture needle core 3 into the hollow puncture needle 1, so that the hollow blade 2 and the solid blade The port 31 is on the same horizontal plane, and then puncture the patient's sampling site to open the tissue opening. After completion, pull out the puncture needle core 3 to the right, leaving the hollow puncture needle 1 in the patient's body, and then close the front-end hollow sampling The needle 4 is inserted into the hollow puncture needle 1.
需要特别说明的是，随着前端封闭式中空取样针4进入中空穿刺针1内，在这个过程中，前端封闭式中空取样针4会带动限位块5向左运动，从而使得限位块5左侧与橡胶块66接触，并对橡胶块66进行挤压，从而辅助前端封闭式中空取样针4左部进入中空穿刺针1内部，之后继续向左推动前端封闭式中空取样针4，使得限位块5左侧与接触块71右侧接触，并对接触块71进行推动，使得接触块71带动楔形杆72向左滑动，第三弹簧73受力拉伸，随着楔形杆72向左滑动，此时按压杆61不再受到锁止固定，第一弹簧63在初始状态下处于受力压缩状态，在第一弹簧63的作用下，卡环62会带动按压杆61向上滑动，从而通过卡环62左侧对限位块5右侧进行固定限位，使得限位块5带动前端封闭式中空取样针4锁止。It should be noted that as the front-end closed hollow sampling needle 4 enters the hollow puncture needle 1, during this process, the front-end closed hollow sampling needle 4 will drive the limit block 5 to move to the left, thereby causing the limit block 5 to move to the left. The left side contacts the rubber block 66 and squeezes the rubber block 66, thereby assisting the left part of the front-end closed hollow sampling needle 4 to enter the hollow puncture needle 1, and then continues to push the front-end closed hollow sampling needle 4 to the left to limit the The left side of the bit block 5 is in contact with the right side of the contact block 71 and pushes the contact block 71 so that the contact block 71 drives the wedge rod 72 to slide to the left. The third spring 73 is stretched by force, and as the wedge rod 72 slides to the left , at this time, the pressing rod 61 is no longer locked and fixed, and the first spring 63 is in a compressed state in the initial state. Under the action of the first spring 63, the snap ring 62 will drive the pressing lever 61 to slide upward, thereby passing the snap. The left side of the ring 62 fixedly limits the right side of the limit block 5, so that the limit block 5 drives the front-end closed hollow sampling needle 4 to lock.
需要说明的是，在前端封闭式中空取样针4向左滑动的过程中，前端封闭式中空取样针4右部的握持部分会接触并推动套筒65内部左侧的收口部分，使得套筒65向左滑动，从而使得第二弹簧64受力压缩，进而辅助前端封闭式中空取样针4稳定穿过中空穿刺针1，在前端封闭式中空取样针4穿过中空穿刺针1后，通过圆弧形刃口41对患者滑膜组织上已经开口的部位进行疏通，避免组织开口封闭，圆弧形刃口41的左侧端部能够疏通组织开口，同时由于圆弧形刃口41左侧端部为弧面结构，能够有效防止圆弧形刃口41对组织造成额外伤害，当圆弧形刃口41左端部进入滑膜组织后，通过圆弧形刃口41上的斜面结构将滑膜组织内被穿刺针芯3穿刺打开的组织通道撑开，进而辅助前端封闭式中空取样针4能够顺利进入滑膜组织内并进行取样，当前端封闭式中空取样针4无法继续推动，此时前端封闭式中空取样针4完全就位，接着通过前端封闭式中空取样针4右端的负压器连通并于负压装置连接，同时启动负压装置，保持前端封闭式中空取样针4内部处于负压状态，之后向下推动按压杆61，使得卡环62向下滑动，第一弹簧63恢复受力压缩状态，此时卡环62左侧不再对限位块5右侧进行限位锁止，使得前端封闭式中空取样针4解锁，在第二弹簧64的作用下，套筒65会带动前端封闭式中空取样针4向右滑动弹出，同时在第三弹簧73的作用下，接触块71会带动楔形杆72向右滑动复位，并协同套筒65对前端封闭式中空取样针4进行推动，此时楔形杆72会重新对按压杆61进行锁止固定。It should be noted that when the front-end closed hollow sampling needle 4 slides to the left, the right holding part of the front-end closed hollow sampling needle 4 will contact and push the closing part on the left side of the sleeve 65, so that the sleeve 65 slides to the left, thereby causing the second spring 64 to be compressed, thereby assisting the front-end closed hollow sampling needle 4 to stably pass through the hollow puncture needle 1. After the front-end closed hollow sampling needle 4 passes through the hollow puncture needle 1, it passes through the circle. The arc-shaped cutting edge 41 dredges the opened parts of the patient's synovial tissue to prevent the tissue opening from closing. The left end of the arc-shaped cutting edge 41 can clear the tissue opening. At the same time, due to the left end of the arc-shaped cutting edge 41 The arc-shaped cutting edge 41 has an arc surface structure, which can effectively prevent the arc-shaped cutting edge 41 from causing additional damage to the tissue. When the left end of the arc-shaped cutting edge 41 enters the synovial tissue, the synovium will be cut through the bevel structure on the arc-shaped cutting edge 41. The tissue channel opened by the puncture needle core 3 opens up the tissue, thereby assisting the front-end closed hollow sampling needle 4 to smoothly enter the synovial tissue and perform sampling. The front-end closed hollow sampling needle 4 cannot continue to push. At this time, the front-end closed hollow sampling needle 4 cannot continue to push. The closed hollow sampling needle 4 is completely in place, and then connected through the negative pressure device on the right end of the front closed hollow sampling needle 4 and connected to the negative pressure device. At the same time, the negative pressure device is started to keep the inside of the front closed hollow sampling needle 4 at negative pressure. state, and then push the pressing rod 61 downward, causing the snap ring 62 to slide downward, and the first spring 63 returns to the compressed state. At this time, the left side of the snap ring 62 no longer limits and locks the right side of the limit block 5. The front-end closed hollow sampling needle 4 is unlocked. Under the action of the second spring 64, the sleeve 65 will drive the front-end closed hollow sampling needle 4 to slide and pop out. At the same time, under the action of the third spring 73, the contact block 71 will The wedge rod 72 is driven to slide to the right to reset, and cooperates with the sleeve 65 to push the front-end closed hollow sampling needle 4. At this time, the wedge rod 72 will lock and fix the pressing rod 61 again.
需要说明的是，在前端封闭式中空取样针4向右弹出的过程中，橡胶块66左侧的限位斜面67会对前端封闭式中空取样针4进行阻挡定位，避免前端封闭式中空取样针4直接弹出，同时前端封闭式中空取样针4上的倒钩44会进行切割取样，在负压吸引的作用下，使得活检样本进入前端封闭式中空取样针4左部的取样斜面槽43内，接着将负压装置与前端封闭式中空取样针4脱离连接，再用力将前端封闭式中空取样针4向右拔出，完成滑膜活检取样。It should be noted that when the front-end closed hollow sampling needle 4 pops up to the right, the limiting slope 67 on the left side of the rubber block 66 will block and position the front-end closed hollow sampling needle 4 to prevent the front-end closed hollow sampling needle from popping up. 4 directly pops out, and at the same time, the barb 44 on the front-end closed hollow sampling needle 4 will cut and sample. Under the action of negative pressure suction, the biopsy sample enters the sampling bevel groove 43 on the left side of the front-end closed hollow sampling needle 4. Then, disconnect the negative pressure device from the front-end closed hollow sampling needle 4, and then forcefully pull out the front-end closed hollow sampling needle 4 to the right to complete synovial biopsy sampling.
一种自动滑膜活检取样组合装置的使用方法，具体步骤如下：A method of using an automatic synovial biopsy sampling combination device. The specific steps are as follows:
步骤1：将穿刺针芯3插入中空穿刺针1内部，之后通过中空穿刺针1和穿刺针芯3配合对患者取样部位进行组织开口；Step 1: Insert the puncture needle core 3 into the hollow puncture needle 1, and then use the hollow puncture needle 1 and the puncture needle core 3 to open the tissue at the patient's sampling site;
步骤2：接着由医护人员将穿刺针芯3拔出，并将前端封闭式中空取样针4插入中空穿刺针1中；Step 2: The medical staff then pulls out the puncture needle core 3 and inserts the closed-front hollow sampling needle 4 into the hollow puncture needle 1;
步骤3：前端封闭式中空取样针4插入完成后，按动回弹机构6对前端封闭式中空取样针4进行锁止限位；Step 3: After the front-end closed hollow sampling needle 4 is inserted, press the rebound mechanism 6 to lock and limit the front-end closed hollow sampling needle 4;
步骤4：当前端封闭式中空取样针4无法推动后，将负压装置与前端封闭式中空取样针4右侧接口连通，保持负压吸引，并向下推动按压杆61，使得前端封闭式中空取样针4解锁弹出，通过前端封闭式中空取样针4左部倒钩44进行切割取样，样本进入取样斜面槽43内；Step 4: After the front-end closed hollow sampling needle 4 cannot be pushed, connect the negative pressure device to the right interface of the front-end closed hollow sampling needle 4, maintain the negative pressure suction, and push the pressing rod 61 downward to make the front-end closed hollow sampling needle 4 The sampling needle 4 is unlocked and popped up, and the left barb 44 of the front-end closed hollow sampling needle 4 is used for cutting and sampling, and the sample enters the sampling slope groove 43;
步骤5：最后将前端封闭式中空取样针4拔出，完成取样操作。Step 5: Finally, pull out the front-end closed hollow sampling needle 4 to complete the sampling operation.
