本发明还提供了一种避免空吸的肾穿刺活检枪的使用方法,具体步骤如下:The present invention also provides a method for using a renal puncture biopsy gun that avoids empty suction, and the specific steps are as follows:

S1、首先通过所述固定组件将所述第一壳体和第二壳体之间拆卸,然后再将所述穿刺活检针插设于所述套管的内部,所述穿刺活检针和所述套管之间套设放置后,再将二者端部的所述连接杆分别卡设于相对于的所述第一连接块一侧的所述第一卡槽中和第二连接块一侧的所述第二卡槽中,实现将所述穿刺活检针和所述套管安装于第一壳体的内部,最后再将第一壳体和第二壳体之间卡和并通过所述固定组件对其进行固定,安装后的所述套管的一端通过所述第一壳体和第二壳体端部开设有的所述半圆槽向外延伸,此时实现所述穿刺活检针和所述套管的端部分别与所述第一弹射组件和所述第二弹射组件之间的连接;S1. First, the first shell and the second shell are disassembled by the fixing assembly, and then the puncture biopsy needle is inserted into the sleeve. After the puncture biopsy needle and the sleeve are sleeved and placed, the connecting rods at the ends of the two are respectively clamped in the first clamping groove on the side of the first connecting block and the second clamping groove on the side of the second connecting block, so that the puncture biopsy needle and the sleeve are installed in the first shell. Finally, the first shell and the second shell are clamped and fixed by the fixing assembly. One end of the sleeve after installation extends outward through the semicircular groove provided at the ends of the first shell and the second shell, and the ends of the puncture biopsy needle and the sleeve are respectively connected to the first ejection assembly and the second ejection assembly;

S2、所述穿刺活检针和所述套管分别与所述第一弹射组件和所述第二弹射组件之间的连接后,在需要对患者进行穿刺活检取样时,首先推动所述第一推动块,使所述穿刺活检针的端部对所述第一弹簧挤压蓄能,待所述第一推动块移动至所述止动齿的一侧时,此时所述弧形棘齿挤压所述止动齿变形且越过所述止动齿,此时即可停止对所述第一推动块的推动,实现对所述穿刺活检针的上进蓄能;S2, after the puncture biopsy needle and the cannula are connected to the first ejection assembly and the second ejection assembly respectively, when it is necessary to perform a puncture biopsy on the patient, the first push block is first pushed to make the end of the puncture biopsy needle squeeze the first spring to store energy, and when the first push block moves to one side of the stop tooth, the arc-shaped ratchet squeezes the stop tooth to deform and pass over the stop tooth, and the push of the first push block can be stopped at this time, so as to realize the upward energy storage of the puncture biopsy needle;

S3、所述穿刺活检针上进蓄能后,此时再推动第二推动块,使其带动所述套管运动,并且拉动所述套管外侧的第二弹簧运动,使所述第二弹簧拉长蓄能,待所述第二推动块带动固定卡钩越过所述钩板一端的钩尖部时,此时所述弹片推动所述钩板下降,使所述钩板的钩尖部对所述固定卡钩限位止动,此时停止对所述第二推动块的推动,实现对所述套管的上进蓄能;S3, after the puncture biopsy needle moves upward and accumulates energy, the second push block is pushed again to drive the sleeve to move, and the second spring outside the sleeve is pulled to move, so that the second spring is stretched and accumulates energy. When the second push block drives the fixed hook to pass over the hook tip at one end of the hook plate, the spring sheet pushes the hook plate downward, so that the hook tip of the hook plate stops the fixed hook. At this time, the second push block is stopped to realize the upward energy accumulation of the sleeve.

After the cannula is punctured and positioned, the ejection distance of the puncture biopsy needle is adjusted according to the puncture length required by the puncture position. During the adjustment, the slider inside the first slide groove and the second slide groove is adjusted by the adjustment component to adjust the distance between the slider and the first push block and the second push block. At this time, the ejection distance of the puncture biopsy needle and the cannula can be adjusted;

After the ejection distance is adjusted, the push handle at the end of the first shell is pushed, so that the fixed block drives the elastic strips on both sides below to slide inside the guide rail, so that the clamping block on the side wall of the end of the elastic strip moves in the buckle groove. At this time, the fixed block drives the stop tooth to move upward, so that the stop tooth is separated from the arc-shaped ratchet tooth, so that the first ejection assembly is triggered to eject. At this time, the first spring releases elastic potential energy to push the puncture biopsy needle out so that the end with the cutting groove at the end thereof is inserted into the tissue to take tissue samples;

S7、第一弹射组件触发弹射后,能够通过所述撞击杆推动第二弹射组件触发弹射,使所述第二弹簧释放弹性势能,推动所述套管伸出并且穿刺进入到穿刺组织中,此时所述套管内部的弧形切刀能够对所述切割槽中取样的组织进行切割,使切割后的组织停留到所述切割槽中,并且所述套管能够对所述穿刺活检针进行覆盖套设,提高取样后组织在所述切割槽中存放的安全性;S7. After the first ejection assembly is triggered to eject, the impact rod can push the second ejection assembly to trigger the ejection, so that the second spring releases elastic potential energy, pushes the sleeve to extend and puncture into the punctured tissue, and at this time, the arc-shaped cutter inside the sleeve can cut the sampled tissue in the cutting groove, so that the cut tissue stays in the cutting groove, and the sleeve can cover the puncture biopsy needle, thereby improving the safety of the sampled tissue stored in the cutting groove;

S8、穿刺取样后,将所述套管从患者的穿刺部位拔出,推动第二推动块移动,动作重复S使所述套管再次处于上进蓄能状态,此时能够将所述套管中的所述穿刺活检针端部的切割槽裸露,再将所述切割槽中取样的组织去取出即可,此时即可完成穿刺活检组织取样的过程。S8. After puncture sampling, the cannula is pulled out from the puncture site of the patient, and the second push block is pushed to move. The action S is repeated to put the cannula in the upward energy storage state again. At this time, the cutting groove at the end of the puncture biopsy needle in the cannula can be exposed, and the sampled tissue in the cutting groove can be taken out. At this time, the puncture biopsy tissue sampling process can be completed.

在对肾穿刺活检枪进行使用时:首先通过固定组件将第一、第二壳体之间打开分离,然后再将所需要使用的穿刺活检针5插入到套管7中,实现穿刺活检针5与套管7之间的插设连接,再将套设连接完成后的穿刺活检针5与套管7均放置于第一壳体1中,并且使穿刺活检针5和套管7端部的连接杆8分别插设于第一弹射组件和第二弹射组件中的第一连接块27一侧的第一卡槽28和第二连接块40一侧的第二卡槽41中,此时即可实现穿刺活检针5和套管7分别与第一弹射组件和第二弹射组件之间的连接,在对于穿刺活检针5和套管7放置于第一壳体1中时,使其端部侧壁的导向块9滑动放置于内壁上的导向槽4中,能够实现穿刺活检针5和套管7别弹射时,滑动的稳定性。When using the renal puncture biopsy gun: first, the first and second shells are opened and separated by the fixing assembly, and then the puncture biopsy needle 5 to be used is inserted into the sleeve 7 to realize the insertion connection between the puncture biopsy needle 5 and the sleeve 7, and then the puncture biopsy needle 5 and the sleeve 7 after the sleeve connection are completed are placed in the first shell 1, and the connecting rod 8 at the end of the puncture biopsy needle 5 and the sleeve 7 is respectively inserted into the first card slot 28 on the side of the first connecting block 27 in the first ejection assembly and the second ejection assembly. The second card slot 41 on the side of the second connecting block 40 can be realized at this time. The connection between the puncture biopsy needle 5 and the sleeve 7 and the first ejection assembly and the second ejection assembly can be realized. When the puncture biopsy needle 5 and the sleeve 7 are placed in the first shell 1, the guide block 9 on the side wall of the end thereof is slidably placed in the guide groove 4 on the inner wall, which can realize the sliding stability of the puncture biopsy needle 5 and the sleeve 7 when they are ejected.

在对穿刺活检针5和套管7与第一、第二弹射组件放置完成后,此时再将第二壳体2卡设于第一壳体1的一侧,并且使穿刺活检针5和套管7端部的导向块9滑动设于导向槽4中,实现穿刺活检针5和套管7在第一、第二壳体中滑动放置的稳定性,并且使第一、第二壳体端部的半圆槽3拼接成圆孔,使套管7穿过向第一、第二壳体的外侧延伸,第一、第二壳体之间卡设完成后,通过固定组件再将第一、第二壳体之间固定连接,即可实现第一、第二壳体之间的安装固定,增加了第一、第二壳体之间安装拆卸的方便性,同时方便对穿刺活检针5和套管7的安装拆卸更换,且方便对第一、第二壳体内部的第一、第二弹射组件的维修。After the placement of the puncture biopsy needle 5 and the sleeve 7 with the first and second ejection assemblies is completed, the second shell 2 is clamped on one side of the first shell 1, and the guide block 9 at the end of the puncture biopsy needle 5 and the sleeve 7 is slidably set in the guide groove 4 to achieve the stability of the sliding placement of the puncture biopsy needle 5 and the sleeve 7 in the first and second shells, and the semicircular grooves 3 at the ends of the first and second shells are spliced into round holes, so that the sleeve 7 extends to the outside of the first and second shells. After the clamping between the first and second shells is completed, the first and second shells are fixedly connected by the fixing assembly to achieve the installation and fixation between the first and second shells, which increases the convenience of installation and disassembly between the first and second shells, and at the same time facilitates the installation, disassembly and replacement of the puncture biopsy needle 5 and the sleeve 7, and facilitates the maintenance of the first and second ejection assemblies inside the first and second shells.

穿刺活检针5和套管7在第一、第二壳体的内部放置完成后,此时使用者先对第一滑槽10中的第一推动块26进行推动,并且使第一推动块26向靠近止动齿30的一侧推动,第一推动块26被推动时能够同步带动第一连接块27的移动,此时第一连接块27一侧固定安装的弧形棘齿29同步移动,待弧形棘齿29移动至止动齿30的位置时,此时弧形棘齿29能够对止动齿30造成挤压使其变形发生形变,待弧形棘齿29越过止动齿30时,此时止动齿30不受挤压复位发生响声,此时使用者听到响声即可停止对第一推动块26的推动,而此时卡设在第一连接块27一侧第一卡槽28中的穿刺活检针5同步移动后停止移动,停止移动的穿刺活检针5的一端能够对第一壳体1内部放置的第一弹簧24造成挤压,使第一弹簧24压缩储备弹性势能,并且实现对穿刺活检针5进行上进蓄能;该操作实现穿刺活检针5上进蓄能操作的方便性。After the puncture biopsy needle 5 and the sleeve 7 are placed inside the first and second shells, the user first pushes the first push block 26 in the first slide groove 10, and pushes the first push block 26 to the side close to the stop tooth 30. When the first push block 26 is pushed, it can synchronously drive the movement of the first connecting block 27. At this time, the arc-shaped ratchet 29 fixedly installed on one side of the first connecting block 27 moves synchronously. When the arc-shaped ratchet 29 moves to the position of the stop tooth 30, the arc-shaped ratchet 29 can squeeze the stop tooth 30 to deform it. When the first push block 26 is pushed over by the stop tooth 30, the stop tooth 30 is not squeezed and reset to make a sound. At this time, the user can stop pushing the first pushing block 26 after hearing the sound. At this time, the puncture biopsy needle 5 stuck in the first slot 28 on one side of the first connecting block 27 moves synchronously and then stops moving. One end of the stopped puncture biopsy needle 5 can squeeze the first spring 24 placed inside the first shell 1, so that the first spring 24 is compressed to reserve elastic potential energy, and the puncture biopsy needle 5 is moved upward and stored energy. This operation realizes the convenience of the upward energy storage operation of the puncture biopsy needle 5.

在对穿刺活检针5进行上进蓄能后,此时推动第二滑槽11中的第二推动块39,第二推动块39的向靠近钩板43的一侧运动,第二推动块39滑动时能够带动第二连接块40同步运动,此时带动第二连接块40一侧固定连接的固定卡钩42运动,待固定卡钩42移动至钩板43的下方时,此时固定卡钩42的倾斜面一侧能够对钩板43一端的钩尖造成挤压,使钩板43端部的钩尖部挤压变形,待固定卡钩42越过钩板43端部的钩尖时,此时钩尖复位弹出对固定卡钩42造成限位,此时固定卡钩42限位固定,停止对第二推动块39的推动,由于第二连接块40一侧的第二卡槽41中安装有套管7一端的连接杆8,在第二连接块40同步移动时能够带动套管7的同步移动,待套管7移动时能够拉动第二弹簧38拉伸,使第二弹簧38拉伸储备弹性势能,实现套管7的上进蓄能。After the puncture biopsy needle 5 is advanced and stored energy, the second pushing block 39 in the second slide groove 11 is pushed, and the second pushing block 39 moves toward the side close to the hook plate 43. When the second pushing block 39 slides, it can drive the second connecting block 40 to move synchronously, and at this time drive the fixed hook 42 fixedly connected to one side of the second connecting block 40 to move. When the fixed hook 42 moves to the bottom of the hook plate 43, the inclined surface of the fixed hook 42 can squeeze the hook tip at one end of the hook plate 43, so that the hook tip at the end of the hook plate 43 is squeezed and deformed. When the fixed hook 42 passes over the hook tip at the end of the hook plate 43, the hook tip resets and pops out to limit the fixed hook 42. At this time, the fixed hook 42 is limited and fixed, and the pushing of the second pushing block 39 is stopped. Since the connecting rod 8 at one end of the sleeve 7 is installed in the second slot 41 on one side of the second connecting block 40, the sleeve 7 can be driven to move synchronously when the second connecting block 40 moves synchronously. When the sleeve 7 moves, the second spring 38 can be pulled to stretch, so that the second spring 38 stretches and reserves elastic potential energy, thereby realizing the upward energy storage of the sleeve 7.

穿刺活检针5和套管7均上进蓄能后,此时配合B超设备使用,将才套管7穿刺到患者需要的穿刺的部位,然后根据需要穿刺的长度对套管7和穿刺活检针5的穿刺弹射长度进行调节,调节时,首先拉动手柄19,手柄19拉动能够拉动转杆18移动,转杆18带动齿轮17在齿板16上滑动使齿轮17的一端于内齿环22之间分离,此时齿轮17不受内齿环22的限位,并且复位弹簧23处于压缩状态,此时工作人员转动转杆18,转杆18转动能够带动齿轮17转动,齿轮17转动啮合齿板16,使齿板16在水平方向上移动,由于齿板16固定安装于U型杆14上,即可带动U型杆14的运动,并且U型杆14的两端滑块12分别滑动设于第一、第二滑槽的内部,即可实现带动滑块12与第一、第二推动块之间的距离调节,在第一、第二推动块在第一、第二滑槽的内部滑动时此时的滑块12能够对其起到限位的作用,即可对穿刺活检针5和套管7弹射穿刺的位置起到穿刺长度调节的作用,避免穿刺位置造成穿透,降低了穿刺操作的危险性。After the puncture biopsy needle 5 and the sleeve 7 are both advanced and energized, they are used in conjunction with the B-ultrasound equipment to puncture the sleeve 7 to the puncture site required by the patient, and then the puncture ejection length of the sleeve 7 and the puncture biopsy needle 5 is adjusted according to the required puncture length. When adjusting, first pull the handle 19, and the handle 19 can pull the rotating rod 18 to move, and the rotating rod 18 drives the gear 17 to slide on the tooth plate 16 so that one end of the gear 17 is separated between the inner tooth ring 22. At this time, the gear 17 is not limited by the inner tooth ring 22, and the reset spring 23 is in a compressed state. At this time, the staff rotates the rotating rod 18, and the rotation of the rotating rod 18 can drive the gear 17 to rotate, and the gear The wheel 17 rotates to engage the tooth plate 16, so that the tooth plate 16 moves in the horizontal direction. Since the tooth plate 16 is fixedly installed on the U-shaped rod 14, the movement of the U-shaped rod 14 can be driven, and the sliders 12 at both ends of the U-shaped rod 14 are respectively slidably arranged inside the first and second slide grooves, so as to achieve the distance adjustment between the slider 12 and the first and second pushing blocks. When the first and second pushing blocks slide inside the first and second slide grooves, the slider 12 at this time can limit them, so as to adjust the puncture length of the ejection puncture position of the biopsy needle 5 and the sleeve 7, avoid penetration at the puncture position, and reduce the danger of the puncture operation.

调节组件调节完成后,松开对手柄19的拉动,复位弹簧23复位,能够拉动转杆18和齿轮17向靠近内齿环22的一侧移动,使齿轮17与内齿环22之间啮合,即可实现对齿轮17的限位,实现U型杆14调节后放置的稳定性,避免第一、第二推动块与滑块12之间造成撞击时,造成U型杆14的晃动移动,增加了U型杆14放置的稳定性。After the adjustment of the adjustment component is completed, the handle 19 is released, and the reset spring 23 is reset, which can pull the rotating rod 18 and the gear 17 to move to the side close to the inner gear ring 22, so that the gear 17 is engaged with the inner gear ring 22, and the gear 17 can be limited. The stability of the U-shaped rod 14 after adjustment is achieved, and the shaking movement of the U-shaped rod 14 caused by the collision between the first and second push blocks and the slider 12 is avoided, thereby increasing the stability of the placement of the U-shaped rod 14.

滑块12与第一、第二推动块之间的距离调节完成后,此时推动第一壳体1一侧调节槽33中的推柄32,推柄32推动能够带动一侧的固定块31在调节槽33的内部滑动,并且带动两侧的弹性条34移动,在固定块31向上移动带动弹性条34向上运动使,此时弹性条34带动卡块35在导轨36内部的扣槽37中移动,并且对弹性条34造成挤压,实现弹性条34在导轨36中的移动,固定块31上移时,带动一端的止动齿30上移,使止动齿30与弧形棘齿29之间分离,弧形棘齿29不受止动齿30的限位时,此时第一弹簧24伸出释放弹性势能,推动穿刺活检针5弹出,穿刺活检针5弹出后其一端带有切割槽6的端部延伸出套管7并且穿刺进入到需要取样的组织中,使组织进入到取样切割槽6中。After the distance between the slider 12 and the first and second pushing blocks is adjusted, the push handle 32 in the adjusting groove 33 on one side of the first shell 1 is pushed. The push handle 32 can drive the fixed block 31 on one side to slide inside the adjusting groove 33, and drive the elastic strips 34 on both sides to move. When the fixed block 31 moves upward, the elastic strip 34 moves upward. At this time, the elastic strip 34 drives the card block 35 to move in the buckle groove 37 inside the guide rail 36, and squeezes the elastic strip 34 to achieve the movement of the elastic strip 34 in the guide rail 36. When the fixed block 31 moves upward, it drives the stop tooth 30 at one end to move upward, so that the stop tooth 30 is separated from the arc ratchet tooth 29. When the arc ratchet tooth 29 is not limited by the stop tooth 30, the first spring 24 extends out to release the elastic potential energy, and pushes the puncture biopsy needle 5 to pop out. After the puncture biopsy needle 5 pops out, the end with the cutting groove 6 at one end extends out of the sleeve 7 and punctures into the tissue to be sampled, so that the tissue enters the sampling cutting groove 6.

穿刺活检针5弹出后,其弧形棘齿29一侧的撞击杆51对顶杆48造成撞击,顶杆48受到撞击后使其在约束筒25和导向筒47的内部滑动,并且带动顶杆48的一端对钩板43造成推动,使钩板43围绕轴杆45转动,轴杆45转动时,能够将钩板43一端的钩尖抬起并且其另一端对弹片46造成挤压,此时钩板43的钩尖部与固定卡钩42之间分离,固定卡钩42失去限位后,第二弹簧38收缩释放弹性势能,拉动套管7向第一、第二壳体的外侧延伸,并且其一端穿刺进入到组织中,并且端部对切割槽6造成覆盖,在套管7弹出时,套管7内部的弧形切刀52能够对切割槽6中的组织造成切割,避免切割槽6中的组织与穿刺部位的整体组织之间粘连,而造成组织取样的难去取出,此时即可实现穿刺后的取样。After the puncture biopsy needle 5 is ejected, the impact rod 51 on one side of its arc-shaped ratchet 29 impacts the push rod 48. After the impact, the push rod 48 slides inside the constraint tube 25 and the guide tube 47, and drives one end of the push rod 48 to push the hook plate 43, so that the hook plate 43 rotates around the shaft rod 45. When the shaft rod 45 rotates, the hook tip at one end of the hook plate 43 can be lifted and the other end can squeeze the spring piece 46. At this time, the hook tip of the hook plate 43 is separated from the fixed hook 42. After the fixed hook 42 loses its limit, the second spring 38 contracts to release elastic potential energy, pulling the sleeve 7 to extend to the outside of the first and second shells, and one end of it punctures into the tissue, and the end covers the cutting groove 6. When the sleeve 7 is ejected, the arc-shaped cutter 52 inside the sleeve 7 can cut the tissue in the cutting groove 6 to avoid adhesion between the tissue in the cutting groove 6 and the overall tissue of the puncture site, which makes it difficult to remove the tissue sample. At this time, sampling after puncture can be achieved.

同时在穿刺活检针5和套管7弹出时,第一、第二推动块均先后与滑块12之间造成撞击限位,避免穿刺活检针5和套管7弹射处的长度过长而造成穿透空吸,降低刺穿出血的危险性,通过调节滑块12与第一、第二推动块之间的距离能够调节控制穿刺活检针5和套管7之间的距离,能够有效的提高穿刺取样的安全性,同时降低了医护工作人员的操作难度,提高了医护人员在对患者进行肾活检穿刺时操作的便捷性和准确性。At the same time, when the puncture biopsy needle 5 and the sleeve 7 are ejected, the first and second pushing blocks successively create collision limits with the slider 12 to avoid the puncture biopsy needle 5 and the sleeve 7 from being too long at the ejection point to cause penetration and air suction, thereby reducing the risk of puncture bleeding. By adjusting the distance between the slider 12 and the first and second pushing blocks, the distance between the puncture biopsy needle 5 and the sleeve 7 can be adjusted and controlled, which can effectively improve the safety of puncture sampling, while reducing the operating difficulty of medical staff, and improving the convenience and accuracy of medical staff in performing renal biopsy puncture on patients.

本发明还提供了一种避免空吸的肾穿刺活检枪及其使用方法,具体步骤如下:The present invention also provides a renal puncture biopsy gun that avoids empty suction and a method for using the same, the specific steps of which are as follows:

S1、首先通过固定组件将第一壳体1和第二壳体2之间拆卸,然后再将穿刺活检针5插设于套管7的内部,穿刺活检针5和套管7之间套设放置后,再将二者端部的连接杆8分别卡设于相对于的第一连接块27一侧的第一卡槽28中和第二连接块40一侧的第二卡槽41中,实现将穿刺活检针5和套管7安装于第一壳体的内部,最后再将第一壳体1和第二壳体2之间卡和并通过固定组件对其进行固定,安装后的套管7的一端通过第一壳体1和第二壳体2端部开设有的半圆槽3向外延伸,此时实现穿刺活检针5和套管7的端部分别与第一弹射组件和第二弹射组件之间的连接;S1. First, the first shell 1 and the second shell 2 are disassembled by the fixing assembly, and then the puncture biopsy needle 5 is inserted into the sleeve 7. After the puncture biopsy needle 5 and the sleeve 7 are placed between them, the connecting rods 8 at the ends of the two are respectively clamped in the first clamping groove 28 on the side of the first connecting block 27 and the second clamping groove 41 on the side of the second connecting block 40, so that the puncture biopsy needle 5 and the sleeve 7 are installed in the first shell. Finally, the first shell 1 and the second shell 2 are clamped and fixed by the fixing assembly. One end of the sleeve 7 after installation extends outward through the semicircular groove 3 provided at the ends of the first shell 1 and the second shell 2, and the ends of the puncture biopsy needle 5 and the sleeve 7 are respectively connected to the first ejection assembly and the second ejection assembly;

S2、穿刺活检针5和套管7分别与第一弹射组件和第二弹射组件之间的连接后,在需要对患者进行穿刺活检取样时,首先推动第一推动块26,使穿刺活检针5的端部对第一弹簧24挤压蓄能,待第一推动块26移动至止动齿30的一侧时,此时弧形棘齿挤压止动齿30变形且越过止动齿30,此时即可停止对第一推动块26的推动,实现对穿刺活检针5的上进蓄能;S2, after the puncture biopsy needle 5 and the sleeve 7 are connected to the first ejection assembly and the second ejection assembly respectively, when it is necessary to perform a puncture biopsy on the patient, first push the first push block 26, so that the end of the puncture biopsy needle 5 squeezes the first spring 24 to store energy, and when the first push block 26 moves to one side of the stop tooth 30, the arc-shaped ratchet squeezes the stop tooth 30 to deform and pass over the stop tooth 30, and then the push of the first push block 26 can be stopped, so that the puncture biopsy needle 5 can be stored upward;

S3、穿刺活检针5上进蓄能后,此时再推动第二推动块39,使其带动套管7运动,并且拉动套管7外侧的第二弹簧38运动,使第二弹簧38拉长蓄能,待第二推动块39带动固定卡钩42越过钩板43一端的钩尖部时,此时弹片46推动钩板43下降,使钩板43的钩尖部对固定卡钩42限位止动,此时停止对第二推动块39的推动,实现对套管7的上进蓄能;S3, after the puncture biopsy needle 5 moves upward and stores energy, the second push block 39 is pushed again to drive the sleeve 7 to move, and the second spring 38 on the outer side of the sleeve 7 is pulled to move, so that the second spring 38 is stretched and stores energy. When the second push block 39 drives the fixed hook 42 to pass over the hook tip at one end of the hook plate 43, the spring piece 46 pushes the hook plate 43 downward, so that the hook tip of the hook plate 43 stops the fixed hook 42. At this time, the second push block 39 is stopped to realize the upward energy storage of the sleeve 7.

S4、穿刺活检针5和套管7均分别上进蓄能后,此时的穿刺活检针5收纳于套管7的内部,然后再将套管7穿刺到患者的穿刺部位,配合B超设备观察套管7的穿刺位置,对套管7的穿刺位置进行定位调整;S4, after the puncture biopsy needle 5 and the cannula 7 are both advanced and energized, the puncture biopsy needle 5 is now stored inside the cannula 7, and then the cannula 7 is punctured into the puncture site of the patient, and the puncture position of the cannula 7 is observed with the help of the B-ultrasound device, and the puncture position of the cannula 7 is positioned and adjusted;

S5、套管7穿刺定位后,此时根据穿刺位置所需要的穿刺长度对穿刺活检针的弹射距离进行调节,调节时,通过调节组件对第一滑槽10和第二滑槽11内部的滑块12进行调节,使滑块12与第一推动块26和第二推动块39之间的距离调节,此时即可实现对穿刺活检针5和套管7的弹射距离进行调节;S5. After the cannula 7 is punctured and positioned, the ejection distance of the puncture biopsy needle is adjusted according to the puncture length required by the puncture position. During the adjustment, the slider 12 inside the first slide groove 10 and the second slide groove 11 is adjusted by the adjustment component to adjust the distance between the slider 12 and the first push block 26 and the second push block 39. At this time, the ejection distance of the puncture biopsy needle 5 and the cannula 7 can be adjusted;

S6、弹射距离调节完成后,此时推动第一壳体1端部的推柄32,使固定块31带动下方两侧的弹性条34在导轨36的内部滑动,使弹性条34端部侧壁的卡块35在扣槽37中移动,此时固定块31带动止动齿30向上移动,使止动齿30与弧形棘齿29之间分离,使第一弹射组件触发弹射,此时第一弹簧24释放弹性势能推动穿刺活检针5伸出使其端部带有切割槽6的一端次入到组织中对其进行组织取样;S6. After the ejection distance is adjusted, the push handle 32 at the end of the first housing 1 is pushed, so that the fixed block 31 drives the elastic strips 34 on both sides below to slide inside the guide rail 36, so that the clamping block 35 on the side wall of the end of the elastic strip 34 moves in the buckle groove 37. At this time, the fixed block 31 drives the stop tooth 30 to move upward, so that the stop tooth 30 is separated from the arc-shaped ratchet 29, so that the first ejection assembly is triggered to eject. At this time, the first spring 24 releases the elastic potential energy to push the puncture biopsy needle 5 to extend so that the end with the cutting groove 6 at the end thereof is inserted into the tissue to take tissue samples;

S7、第一弹射组件触发弹射后,能够通过撞击杆51推动第二弹射组件触发弹射,使第二弹簧38释放弹性势能,推动套管7伸出并且穿刺进入到穿刺组织中,此时套管7内部的弧形切刀52能够对切割槽6中取样的组织进行切割,使切割后的组织停留到切割槽6中,并且套管7能够对穿刺活检针5进行覆盖套设,提高取样后组织在切割槽6中存放的安全性;S7, after the first ejection assembly is triggered to eject, the second ejection assembly can be pushed to trigger the ejection through the impact rod 51, so that the second spring 38 releases the elastic potential energy, pushing the sleeve 7 to extend and puncture into the punctured tissue. At this time, the arc-shaped cutter 52 inside the sleeve 7 can cut the sampled tissue in the cutting groove 6, so that the cut tissue stays in the cutting groove 6, and the sleeve 7 can cover the puncture biopsy needle 5, thereby improving the safety of the sampled tissue stored in the cutting groove 6;

S8、穿刺取样后,将套管7从患者的穿刺部位拔出,推动第二推动块39移动,动作重复S3使套管7再次处于上进蓄能状态,此时能够将套管7中的穿刺活检针5端部的切割槽6裸露,再将切割槽6中取样的组织去取出即可,此时即可完成穿刺活检组织取样的过程。S8, after puncture sampling, the cannula 7 is pulled out from the puncture site of the patient, and the second push block 39 is pushed to move, and the action S3 is repeated to put the cannula 7 in the upward energy storage state again. At this time, the cutting groove 6 at the end of the puncture biopsy needle 5 in the cannula 7 can be exposed, and then the sampled tissue in the cutting groove 6 can be taken out. At this time, the process of puncture biopsy tissue sampling can be completed.
