一种可术中二次麻醉穿刺活检枪An intraoperative needle biopsy gun for secondary anesthesia

技术领域technical field

本发明属于医疗设备技术领域，具体涉及一种可术中二次麻醉穿刺活检枪。The invention belongs to the technical field of medical equipment, and particularly relates to a puncture biopsy gun capable of secondary anesthesia during surgery.

背景技术Background technique

乳腺癌是目前威胁女性生命健康且病死率位居女性恶性肿瘤首位的疾病。乳腺癌发生率呈逐年增长趋势，据报道每年新增病例约21万。早期及时接受正确治疗的乳腺癌患者，其5年生存率高达90%。因此，寻找早期诊断乳腺癌的灵敏有效检测方法对降低乳腺癌病死率、提高患者的生活质量具有重要意义。Breast cancer is a disease that threatens women's life and health and ranks first in female malignant tumors. The incidence of breast cancer is increasing year by year, and it is reported that there are about 210,000 new cases every year. The 5-year survival rate of breast cancer patients who receive the correct treatment at an early stage is as high as 90%. Therefore, finding a sensitive and effective detection method for early diagnosis of breast cancer is of great significance to reduce the mortality rate of breast cancer and improve the quality of life of patients.

随着乳腺癌规范化治疗的进展，新辅助化疗、保乳手术、前哨淋巴结活检等诊治手段日益受到重视，且已成为目前乳腺癌诊治的主流。病理组织学检查结果是乳腺癌诊断的金标准，确切的病理组织学结果更是乳腺癌综合性治疗的前提条件。病理组织学检查包括开放手术活检和穿刺病灶活检。随着影像学引导穿刺活检技术的成熟与进步，开放手术乳腺病灶活检比例逐渐降低。目前，在X线、超声和MRI引导下，通过空芯针穿刺获取病灶组织进行组织病理学诊断在临床中普遍应用。With the progress of standardized treatment of breast cancer, neoadjuvant chemotherapy, breast-conserving surgery, sentinel lymph node biopsy and other methods of diagnosis and treatment have received increasing attention, and have become the mainstream of breast cancer diagnosis and treatment. Histopathological results are the gold standard for breast cancer diagnosis, and exact histopathological results are a prerequisite for comprehensive breast cancer treatment. Histopathological examinations included open surgical biopsy and biopsy of the lesion. With the maturity and progress of imaging-guided needle biopsy technology, the proportion of open surgical breast biopsy has gradually decreased. At present, under the guidance of X-ray, ultrasound and MRI, core needle puncture to obtain lesion tissue for histopathological diagnosis is widely used in clinical practice.

现在常用的穿刺活检枪主要包括穿刺套管、套管内的活检针芯、针芯及套管发射手柄等。其中，套管内的活检针芯为带有斜尖和取材凹槽的光滑不锈钢针，套管为带有斜尖和刻度的不锈钢管。穿刺前，手术医师要对穿刺点皮肤、针道及病灶周围组织进行麻醉。从穿刺点皮肤到取材触发点的过程中，活检针芯缩在套管内，二者一起进入乳腺组织内。到达触发点后，手术医师按下发射按钮，活检针芯和套管便依次先后快速外伸，进入取材凹槽的病变标本便被套管切下并封闭于凹槽中。穿刺活检枪离体后，病变标本于10%中性甲醛溶液固定后送检。The commonly used puncture biopsy guns mainly include puncture cannula, biopsy needle core in the cannula, needle core and cannula launch handle, etc. Wherein, the biopsy needle core in the cannula is a smooth stainless steel needle with a bevel tip and a material sampling groove, and the cannula is a stainless steel tube with a bevel tip and a scale. Before the puncture, the surgeon should anesthetize the skin at the puncture point, the needle tract and the tissues around the lesion. During the process from the puncture point skin to the sampling trigger point, the biopsy needle core is retracted in the cannula, and the two enter the breast tissue together. After reaching the trigger point, the surgeon presses the firing button, and the biopsy needle core and the cannula are rapidly extended one after another, and the lesion specimen that enters the sampling groove is cut off by the cannula and sealed in the groove. After the needle biopsy gun was isolated, the lesion specimens were fixed in 10% neutral formaldehyde solution and sent for examination.

根据药物规定，常规麻醉药物利多卡因单次使用上限不超过400mg。然而， 在麻醉过程中患者往往由于乳房较大或病变部位较深，麻醉穿刺路径较长，深部组织的麻醉效果较差，易引起明显疼痛。According to the drug regulations, the upper limit of single use of conventional anesthetic lidocaine does not exceed 400mg. However, in the process of anesthesia, patients often suffer from significant pain due to larger breasts or deeper lesions, longer anesthesia puncture paths, and poor anesthesia effect in deep tissues.

另外，对位于乳腺近基底部的肿物进行麻醉时，路径长、多次注射麻醉易造成针道肿瘤细胞残留及传播可能。In addition, when anesthetizing a tumor located near the base of the breast, the long path and multiple injections of anesthesia are likely to cause residual tumor cells in the needle tract and may spread.

In addition, it should be noted that, for the convenience of description, the accompanying drawings only show some but not all of the parts related to the present invention.

参见图1-图12，本实施例提供一种可术中二次麻醉穿刺活检枪，其结构包括注射针轴1、取样针2、切削套管3、发射装置、振动发生装置。1-12, the present embodiment provides a needle biopsy gun capable of secondary anesthesia during surgery, the structure of which includes an injection needle shaft 1, a sampling needle 2, a cutting sleeve 3, a launching device, and a vibration generating device.

如图5所示，注射针轴1，后端设置有转盘11，前端与活塞12可拆卸连接。如图6所示，注射针轴1的前端与活塞12通过螺纹连接。As shown in FIG. 5 , the injection needle shaft 1 is provided with aturntable 11 at the rear end, and the front end is detachably connected with thepiston 12 . As shown in FIG. 6 , the front end of the injection needle shaft 1 is connected with thepiston 12 by means of threads.

如图7所示，取样针2呈细长圆柱形，包括穿刺刀头21、连接杆23、针体24，穿刺刀头21与针体24为直径相等的圆柱体同轴设置，连接杆23一端连接穿刺刀头21，另一端连接针体24，穿刺刀头21与针体24开设通孔，穿刺刀头21的外圆柱面上设置有轴向直线槽微织构，直线槽微织构的深度与宽度均为20 μm左右，与细胞尺度大小水平相当，直线槽的长度为10mm一段，沿圆柱表面圆周阵列分布。沿轴向方向上，有若干段直线槽，段与段之间有间隔，每一段各自都沿圆周阵列。连接杆23的直径明显小于穿刺刀头21的直径，以便形成样本的储材凹槽。As shown in FIG. 7 , the sampling needle 2 is slender and cylindrical, and includes apuncture head 21 , a connectingrod 23 , and aneedle body 24 . The puncturinghead 21 and theneedle body 24 are cylindrical bodies with the same diameter and are arranged coaxially. The connectingrod 23 One end is connected to thepuncture head 21, the other end is connected to theneedle body 24, thepuncture head 21 and theneedle body 24 have a through hole, the outer cylindrical surface of thepuncture head 21 is provided with an axial linear groove micro-texture, and the linear groove micro-texture The depth and width of the grooves are both about 20 μm, which is comparable to the size of the cell scale. The length of the straight grooves is 10 mm, and they are distributed in a circular array along the cylindrical surface. In the axial direction, there are several segments of straight grooves, and there are intervals between the segments, and each segment is arrayed along the circumference. The diameter of the connectingrod 23 is significantly smaller than the diameter of thepuncture head 21 in order to form a storage groove for the sample.

如图8所示穿刺刀头21的左端为斜边针尖。如图9所示，穿刺刀头21的左端为三棱刃针尖，切削刃带有锯齿状微织构，锯齿状微织构的形貌，即将棱刃的直线边切除部分材料，变为锯齿状曲线。每个锯齿的长度约为20~50 μm，锯齿状结构可形成多个刺破针尖，使人体软组织更易刺破，配合振动可使传统的针扎软组织作用变为锯削软组织作用，使进针更容易，进针力更小。As shown in FIG. 8 , the left end of thepuncture head 21 is a beveled needle tip. As shown in FIG. 9 , the left end of thepuncture head 21 is a triangular-edged needle tip, and the cutting edge has a sawtooth-like microtexture. The morphology of the sawtooth-like microtexture means that a part of the material is cut off from the straight edge of the edge to become sawtooth. shape curve. The length of each serration is about 20~50 μm. The serrated structure can form multiple puncturing needle tips, which makes the human soft tissue easier to pierce. With vibration, the traditional acupuncture soft tissue function can be changed into sawing soft tissue function, so that the needle can be inserted into the soft tissue. Easier and less force for needle insertion.

如图11、12所示，为切削套管3，呈细长管状，左端部为斜切口刃31，外圆柱面上设置有轴向直线槽微织构，直线槽微织构的深度与宽度均为20 μm左右，与细胞尺度大小水平相当，直线槽的长度为10mm一段，沿圆柱表面圆周阵列分布。沿轴向方向上，有若干段直线槽，段与段之间有间隔，每一段各自都沿圆周阵列。As shown in Figures 11 and 12, it is a cutting sleeve 3, in the shape of a slender tube, the left end is abeveled edge 31, an axial linear groove micro-texture is arranged on the outer cylindrical surface, and the depth and width of the linear groove micro-texture are They are all about 20 μm, which is comparable to the size of cells. The length of the straight grooves is 10 mm, and they are distributed in an array along the circumference of the cylindrical surface. In the axial direction, there are several segments of straight grooves, and there are intervals between the segments, and each segment is arrayed along the circumference.

如图4所示，为注射针轴1、取样针2和切削套管3组装到一起的示意图，其中注射针轴1插入到取样针2的通孔中，切削套管3套装在取样针2的外侧位置。As shown in FIG. 4 , it is a schematic diagram showing that the injection needle shaft 1 , the sampling needle 2 and the cutting sleeve 3 are assembled together, wherein the injection needle shaft 1 is inserted into the through hole of the sampling needle 2 , and the cutting sleeve 3 is sleeved on the sampling needle 2 the outer position.

三者配合，除穿刺软组织外，可以实现两个功能，一个是二次注射麻醉剂，一个是取样。With the cooperation of the three, in addition to puncturing the soft tissue, it can achieve two functions, one is the secondary injection of anesthetics, and the other is sampling.

二次注射麻醉过程。穿刺刀头21端部开设注射孔22，注射孔22与穿刺刀头21的通孔连通。注射针轴1连接活塞12插入取样针2的通孔中，活塞12位于穿刺刀头21的通孔中，往后抽动注射针轴1，使活塞12位于穿刺刀头21的右端内位置（但不到达储材凹槽处），将麻醉剂通过注射孔22被吸入到穿刺刀头21的通孔腔中。取样针2插入到发射之后，往前推动注射针轴1，使麻醉剂从注射孔22注射到软组织深部的靶点区域，对待切割部位进行二次麻醉。Secondary injection anesthesia procedure. Aninjection hole 22 is provided at the end of thepuncture cutter head 21 , and theinjection hole 22 communicates with the through hole of thepuncture cutter head 21 . The injection needle shaft 1 is connected to thepiston 12 and inserted into the through hole of the sampling needle 2, thepiston 12 is located in the through hole of thepuncture head 21, and the injection needle shaft 1 is pulled backward so that thepiston 12 is located in the right end of the puncture head 21 (but not reaching the material storage groove), the anesthetic is sucked into the through-hole cavity of thepuncture head 21 through theinjection hole 22 . After the sampling needle 2 is inserted into the firing, the injection needle shaft 1 is pushed forward, so that the anesthetic is injected from theinjection hole 22 into the target area deep in the soft tissue, and the to-be-cut site is anesthetized for a second time.

如图6所示，活塞12的前端有一个缺口。如图10所示，为防转挡块28设置于穿刺刀头21的内孔端部。当活塞12注射完麻醉剂的过程中或之后，适当转动注射针轴1，使活塞12刚好与防转挡块28卡合，然后活塞12就不能转动了。也可以设置其他结构，在麻醉剂注射完后，使活塞在穿刺刀头21的内孔前端部不能转动。As shown in FIG. 6, the front end of thepiston 12 has a notch. As shown in FIG. 10 , ananti-rotation block 28 is provided at the end of the inner hole of thepuncture cutter head 21 . During or after the injection of the anesthetic agent into thepiston 12, the injection needle shaft 1 is properly rotated so that thepiston 12 is just engaged with theanti-rotation stopper 28, and then thepiston 12 cannot be rotated. Other structures may also be provided to prevent the piston from rotating at the front end of the inner hole of thepuncture head 21 after the anesthetic is injected.

注射完毕之后， 活塞12在穿刺刀头21的通孔中只能前后滑动，不能转动，这样，通过旋转转盘11，使注射针轴2与活塞12螺纹拆卸开，将活塞12留在穿刺刀头21内部，以防止取样过程中样本通过注射口污染针道组织。然后将注射轴2拔出即可。After the injection is completed, thepiston 12 can only slide back and forth in the through hole of thepuncture head 21, but cannot rotate. In this way, by rotating theturntable 11, the injection needle shaft 2 and thepiston 12 are threadedly disassembled, and thepiston 12 is left in the puncture head. 21 inside to prevent the sample from contaminating the needle tract tissue through the injection port during the sampling process. Then pull out the injection shaft 2.

取样过程。如图8所示，连接杆23的直径明显小于穿刺刀头21的直径。当切削套管3在取样针2上滑动过程中，其他位置二者之间的间隙很小，而在连接杆23的位置却有较大的空隙。当取样针2插入软组织之后，此时，切削套管3从取样针2的后端位置快速滑动至穿刺刀头21的部位，经过连接杆23的位置时，就将位于此处的软组织切削下来，并封闭于二者之间的位置。然后，再将二者从软组中拔出，就完成了软组织的取样。sampling process. As shown in FIG. 8 , the diameter of the connectingrod 23 is significantly smaller than the diameter of thepuncture cutter head 21 . When the cutting sleeve 3 slides on the sampling needle 2 , the gap between the other positions is very small, but the position of the connectingrod 23 has a relatively large gap. After the sampling needle 2 is inserted into the soft tissue, at this time, the cutting sleeve 3 quickly slides from the rear end position of the sampling needle 2 to the position of thepuncture head 21, and when passing through the position of the connectingrod 23, the soft tissue located there is cut off , and is enclosed in a position between the two. Then, the two were pulled out from the soft group to complete the soft tissue sampling.

直线槽微织构，在穿刺过程中，直线槽中可以储存组织液，起到润滑的作用，可以降低切削套管和取样针的穿刺摩擦力。直线槽微织构在套管圆柱表面呈圆周阵列分布，其阵列数量根据穿刺需要灵活设置；直线槽的深度及宽度为~20 μm，与细胞尺度水平同等；直线槽的长度为10 mm，两刻度之间区域的轴向数量根据穿刺需要灵活设置。Linear groove micro-texture, in the process of puncture, tissue fluid can be stored in the linear groove, which plays a role of lubrication and can reduce the puncture friction of cutting cannula and sampling needle. The micro-textures of the linear grooves are distributed in a circular array on the cylindrical surface of the casing, and the number of the arrays can be flexibly set according to the needs of puncture; the depth and width of the linear grooves are ~20 μm, which is the same as the level of the cell scale; the length of the linear grooves is 10 mm, two The axial number of the area between the scales can be set flexibly according to the needs of puncture.

微织构的存在，使得在穿刺的过程中，微织构中可以存储一定量的组织液，该组织液起到良好的润滑作用，减小了摩擦力，降低了穿刺阻力，减少疼痛感。The existence of the micro-texture enables a certain amount of tissue fluid to be stored in the micro-texture during the puncture process, which has a good lubricating effect, reduces friction, reduces puncture resistance, and reduces pain.

同时微织构可以存储少量的麻醉剂，对穿刺通道进行麻醉，降低疼痛感。At the same time, the microstructure can store a small amount of anesthesia, anesthetize the puncture channel, and reduce pain.
