本实用新型涉及活检钳领域，特别涉及一种可调节心肌活检钳。The utility model relates to the field of biopsy forceps, in particular to an adjustable myocardial biopsy forceps.
背景技术Background Art
心内膜心肌活检是一种医学检验方式。心肌活检主要是检查心脏有没有心肌的病变，比如心肌炎、扩张型心肌病、肥厚型心肌病、心肌淀粉样病变、心脏肿瘤、心肌的结缔组织病、心脏本身的心肌疾病，只能通过心肌活检来确诊。其他的辅助检查包括心脏磁共振、心脏彩超、心电图只能是间接的诊断。想要明确诊断，只能通过心肌活检来以确诊，进而针对病因进行有效的治疗，心肌活检是介入性的诊断技术。由于心肌活检能提供活体心脏组织进行光镜、电镜、组织化学、免疫学和病毒学等的研究，因此对某些心血管疾病具有重要的诊断和鉴别诊断价值。Endomyocardial biopsy is a medical examination method. Myocardial biopsy is mainly used to check whether there are myocardial lesions in the heart, such as myocarditis, dilated cardiomyopathy, hypertrophic cardiomyopathy, myocardial amyloid lesions, cardiac tumors, myocardial connective tissue diseases, and myocardial diseases of the heart itself. They can only be diagnosed through myocardial biopsy. Other auxiliary examinations including cardiac magnetic resonance imaging, cardiac ultrasound, and electrocardiogram can only be indirect diagnoses. If you want to make a clear diagnosis, you can only confirm it through myocardial biopsy, and then carry out effective treatment for the cause. Myocardial biopsy is an interventional diagnostic technique. Since myocardial biopsy can provide living heart tissue for light microscopy, electron microscopy, histochemistry, immunology, and virology research, it has important diagnostic and differential diagnostic value for certain cardiovascular diseases.
现有的心机活检钳，需要对活检组织的位置实施穿刺操作，随后，将活检钳的摘取端伸入患者体内，摘取一定量的组织后去取出送检，在该过程中，需要等待穿刺针进入指定位置后，再操作活检钳的摘取端到达活检组织在体内所处的位置，需要实施两次介入操作，患者的不适感增加，活检取样工作耗费的时间较长。Existing cardiac biopsy forceps need to perform a puncture operation on the location of the biopsy tissue, and then extend the picking end of the biopsy forceps into the patient's body to remove a certain amount of tissue and then take it out for inspection. In this process, it is necessary to wait for the puncture needle to enter the specified position, and then operate the picking end of the biopsy forceps to reach the location of the biopsy tissue in the body. Two intervention operations are required, which increases the patient's discomfort and takes a long time for biopsy sampling.

具体实施方式DETAILED DESCRIPTION
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本实用新型保护的范围。The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
实施例：参考图1、图2所示的一种可调节心肌活检钳，包括中空结构的穿刺针1，穿刺针1的前端为入体端11，且穿刺针1的后端固定连接有与其同轴分布的定位座12。还包括有贯穿于穿刺针1、定位座12的取样针2，取样针2与穿刺针1、定位座12同轴分布，且取样针2的前端为摘取尖端21。在活检取样的操作过程中，医护人员需要控制穿刺针1刺入患者体内，到达指定的活检取样位置，随着穿刺针1的入体端11刺入患者体内，取样针2也同步进入患者体内，无需再次插入取样针2，工作人员可在患者体外操作取样针2摘取组织，获取样品。Embodiment: Referring to an adjustable myocardial biopsy forceps shown in FIG. 1 and FIG. 2, the forceps includes a puncture needle 1 with a hollow structure, the front end of the puncture needle 1 is an in-body end 11, and the rear end of the puncture needle 1 is fixedly connected to a positioning seat 12 coaxially arranged therewith. It also includes a sampling needle 2 that penetrates the puncture needle 1 and the positioning seat 12, the sampling needle 2 is coaxially arranged with the puncture needle 1 and the positioning seat 12, and the front end of the sampling needle 2 is a removal tip 21. During the biopsy sampling operation, medical staff need to control the puncture needle 1 to penetrate into the patient's body and reach the designated biopsy sampling position. As the in-body end 11 of the puncture needle 1 penetrates into the patient's body, the sampling needle 2 also enters the patient's body synchronously, and there is no need to insert the sampling needle 2 again. The staff can operate the sampling needle 2 outside the patient's body to remove tissue and obtain samples.
取样针2的尾端外侧设置有控制部3，控制部3靠近定位座12的一侧固定连接有可容纳定位座12置入的容置套31，定位座12的外表面向外延伸形成一对限制块13，限制块13插接于容置套31的侧表面。A control unit 3 is provided on the outside of the tail end of the sampling needle 2. A receiving sleeve 31 capable of accommodating the receiving sleeve 12 is fixedly connected to the side of the control unit 3 close to the positioning seat 12. The outer surface of the positioning seat 12 extends outward to form a pair of limiting blocks 13. The limiting blocks 13 are inserted into the side surface of the receiving sleeve 31.
通过定位座12、限制块13与容置套31的连接，使得穿刺针1可活动安装、拆卸于控制部3前侧，以达到将取样针2安装于穿刺针1外侧的目的。在取样操作的过程中，保持穿刺针1、取样针2移动过程中的一致性，以便于快速实施取样操作。By connecting the positioning seat 12, the limiting block 13 and the accommodating sleeve 31, the puncture needle 1 can be movably installed and removed on the front side of the control unit 3, so as to achieve the purpose of installing the sampling needle 2 outside the puncture needle 1. During the sampling operation, the consistency of the movement of the puncture needle 1 and the sampling needle 2 is maintained to facilitate the rapid implementation of the sampling operation.
如图2、图3所示，容置套31的前端设置有两组斜伸软杆32，每组斜伸软杆32的数量为两个并且对称分布于限制块13的上、下方。斜伸软杆32位于限制块13前侧的一端均呈球形结构，球形结构内侧填充有磁力球33，自然状态下，位于限制块13前侧上、下分布的磁力球33相吸附，上、下分布的斜伸软杆32紧密连接，可有效避免定位座12以及限制块13脱离容置套31，提升穿刺针1的稳定性。As shown in Fig. 2 and Fig. 3, two groups of obliquely extending soft rods 32 are arranged at the front end of the accommodating sleeve 31, and the number of each group of obliquely extending soft rods 32 is two and they are symmetrically distributed above and below the limiting block 13. The ends of the obliquely extending soft rods 32 located in front of the limiting block 13 are all spherical structures, and the inner side of the spherical structure is filled with magnetic balls 33. In a natural state, the magnetic balls 33 located in the upper and lower parts of the front side of the limiting block 13 are attracted to each other, and the obliquely extending soft rods 32 distributed in the upper and lower parts are tightly connected, which can effectively prevent the positioning seat 12 and the limiting block 13 from detaching from the accommodating sleeve 31, and improve the stability of the puncture needle 1.
在安装定位座12以及取样针2的过程中，随着限制块13的挤压，上、下分布的斜伸软杆32的端部相分离，定位座12和限制块13可顺利插接于容置套31的内侧，具有便携安装的优势。During the installation of the positioning seat 12 and the sampling needle 2, as the limiting block 13 is squeezed, the ends of the upper and lower obliquely extending soft rods 32 are separated, and the positioning seat 12 and the limiting block 13 can be smoothly inserted into the inner side of the accommodating sleeve 31, which has the advantage of portable installation.
在整个心肌活检钳的使用过程中，通过定位座12、限制块13与容置套31的连接，可保持穿刺针1与控制部3连接的紧密性，随着穿刺针1的入体端11刺入患者体内，取样针2也同步进入患者体内，无需再次插入取样针2。当取样工作完成后，可同步拔出穿刺针1以及取样针2，再拆卸取样针2，获取活检组织，并且对穿刺针1、取样针2实施清洁操作。在该过程中，降低了患者的不适，提升了穿刺工作的效率。During the entire use of the myocardial biopsy forceps, the connection between the positioning seat 12, the limiting block 13 and the accommodating sleeve 31 can maintain the tightness of the connection between the puncture needle 1 and the control unit 3. As the entry end 11 of the puncture needle 1 penetrates into the patient's body, the sampling needle 2 also enters into the patient's body synchronously, and there is no need to insert the sampling needle 2 again. When the sampling work is completed, the puncture needle 1 and the sampling needle 2 can be pulled out synchronously, and then the sampling needle 2 can be disassembled to obtain the biopsy tissue, and the puncture needle 1 and the sampling needle 2 can be cleaned. In this process, the patient's discomfort is reduced and the efficiency of the puncture work is improved.
如图5所示，取样针2的尾端固定连接有导向杆22，导向杆22的尾端固定连接有手柄23。手柄23可控制导向杆22与取样针2同步移动以及转动，摘取患者的部分组织。As shown in Fig. 5, the tail end of the sampling needle 2 is fixedly connected to a guide rod 22, and the tail end of the guide rod 22 is fixedly connected to a handle 23. The handle 23 can control the guide rod 22 to move and rotate synchronously with the sampling needle 2 to remove part of the patient's tissue.
如图4所示，控制部3的尾端转动连接有导入部34，导向杆22的前端延伸至导入部34的外侧，当导向杆22、取样针2滑移露出入体端11时，导向杆22在导入部34的内侧直线滑动。通过导向杆22与导入部34的连接，工作人员可位于控制部3的后方实施取样针2的推进操作，以便于摘取尖端21顺利接触组织。As shown in FIG4 , the rear end of the control part 3 is rotatably connected to the introduction part 34, and the front end of the guide rod 22 extends to the outside of the introduction part 34. When the guide rod 22 and the sampling needle 2 slide to expose the body entry end 11, the guide rod 22 slides linearly inside the introduction part 34. Through the connection between the guide rod 22 and the introduction part 34, the staff can be located behind the control part 3 to implement the pushing operation of the sampling needle 2, so that the extraction tip 21 can smoothly contact the tissue.
如图4所示，导向杆22的表面开设有导向通道221，导入部34的表面开设有通孔，通孔、导向通道221通过定位销4相连接，当导向杆22、取样针2滑移露出入体端11时，导向通道221在导入部34的内侧直线滑动，定位销4可避免导向杆22滑移过度，保障了摘取尖端21取样过程中的精准度。当摘取尖端21刺入组织内后，可操作手柄23转动，取样针2、导向杆22同步转动，位于导向杆22外侧的导入部34同步转动，顺利将需要活检的组织摘下。As shown in FIG4 , a guide channel 221 is provided on the surface of the guide rod 22, and a through hole is provided on the surface of the introduction part 34. The through hole and the guide channel 221 are connected by a positioning pin 4. When the guide rod 22 and the sampling needle 2 slide to expose the body end 11, the guide channel 221 slides linearly inside the introduction part 34. The positioning pin 4 can prevent the guide rod 22 from sliding excessively, thereby ensuring the accuracy of the sampling process of the extraction tip 21. After the extraction tip 21 penetrates into the tissue, the handle 23 can be operated to rotate, the sampling needle 2 and the guide rod 22 rotate synchronously, and the introduction part 34 located outside the guide rod 22 rotates synchronously, so that the tissue to be biopsied can be removed smoothly.
在转移样品的过程中，需要拆卸定位销4，接触其对导向杆22和导入部34之间的限位连接，随后，可顺利拆卸手柄23、导向杆22以及取样针2，将样品转移至容器内部后送检。During the sample transfer process, the positioning pin 4 needs to be removed to contact the limiting connection between the guide rod 22 and the introduction part 34. Then, the handle 23, the guide rod 22 and the sampling needle 2 can be removed smoothly to transfer the sample to the inside of the container for inspection.
如图4所示，控制部3的外表面均延伸形成一对手持块35，增设有手持块35的目的是便于医护人员手持控制部3，以达到便携操作的目的。As shown in FIG. 4 , the outer surface of the control unit 3 is extended to form a pair of hand-held blocks 35 . The hand-held blocks 35 are provided to facilitate medical personnel to hold the control unit 3 so as to achieve the purpose of portable operation.
