一种输卵管诊断疏通装置A device for diagnosis and dredging of fallopian tubes

技术领域technical field

本发明涉及医疗器械技术领域，特别是涉及一种输卵管诊断疏通装置。The invention relates to the technical field of medical devices, in particular to a device for diagnosing and dredging fallopian tubes.

背景技术Background technique

输卵管通液是利用美蓝液或生理盐水自宫颈注入宫腔，再从宫腔流入输卵管，根据推注药液时阻力的大小及液体返流的情况，判断输卵管是否通畅。目前，临床输卵管通液器在使用时，通常将子宫通液导管按探针检测方向插入颈管，固定于事先选择的深度，然后将溶液缓推注入液体；若液体顺利注入，则无阻力，宫颈外无漏液，病人也无明显不适，表示输卵管通畅；若遇阻力，稍加压力，病人稍有腹部不适即可顺利注入，表示输卵管通而不畅；当感阻力大，液体自宫颈外口溢出，腹部胀难忍，多为输卵管完全不通。并且，通液时，听诊器在下腹两侧可听到液体自输卵管伞端冒出之声音。Tubal fluid is injected from the cervix into the uterine cavity with methylene blue solution or normal saline, and then flows into the fallopian tube from the uterine cavity. According to the resistance and fluid reflux when the drug is injected, it is judged whether the fallopian tube is unobstructed. At present, when the clinical tubal infusion device is used, the uterine infusion catheter is usually inserted into the cervical canal according to the detection direction of the probe, fixed at the depth selected in advance, and then the solution is slowly pushed into the liquid; if the liquid is injected smoothly, there is no resistance. If there is no leakage outside the cervix and the patient has no obvious discomfort, it means that the fallopian tube is unobstructed; if there is resistance, a little pressure is applied, and the patient can inject smoothly with slight abdominal discomfort, which means that the fallopian tube is not smooth; when the resistance is large, the liquid flows from the outside of the cervix The mouth overflows, the abdomen is unbearably bloated, and most of them are completely obstructed fallopian tubes. Moreover, when the fluid is passed, the stethoscope can hear the sound of the fluid coming out of the umbrella end of the fallopian tube on both sides of the lower abdomen.

综上可知，通液时前方压力多少完全是通过操作人员的自我经验进行判断，该方式对操作人员要求极高，易出现误诊，还有可能出现输卵管破裂的危险。并且，近年来随着通液器材料和技术的进步，通液管可以在导丝的导引下直接到达一侧输卵管近宫腔端，除了可以检查输卵管是否通畅，对于黏连较轻的，同时也可以进行输卵管通液治疗。但这样就更增加了输卵管是否通畅的判断难度，降低输卵管诊断的准确度，单纯凭医生经验和手感，容易发生医疗事故。To sum up, it can be seen that the amount of frontal pressure during fluid passage is completely judged by the operator's self-experience. This method has extremely high requirements on the operator, is prone to misdiagnosis, and may cause the risk of tubal rupture. Moreover, in recent years, with the advancement of the material and technology of the fluid-through device, the fluid-through tube can directly reach the end of the fallopian tube near the uterine cavity under the guidance of the guide wire. In addition to checking whether the fallopian tube is unobstructed, for those with mild adhesions, Tubal fluid therapy can also be performed at the same time. But this increases the difficulty of judging whether the fallopian tube is unobstructed, reduces the accuracy of fallopian tube diagnosis, and medical accidents are prone to occur simply by doctor's experience and feel.

Afterwards, the pressuresensing guide wire 40 is moved forward toward the distal end, and the guide wire head end 41 passes through the firstliquid hole 32 at the distal end of theinner catheter 30 and the distal throughhole 22 at the distal end of theouter sheath 20 in sequence. Out of theouter sheath 20, as shown in Figure 15, theguide wire tip 41 is inserted into the interstitial part of the fallopian tube under the hysteroscope, and theguide wire tip 41 is reacted by the interstitial part of the fallopian tube, and the reaction force is transmitted to thepressure sensor 50 , thecontroller 10 displays the pressure value fed back by thepressure sensor 50 in real time on thestatus indication panel 80, and the doctor finds out the best insertion angle for theguide wire tip 41 to be inserted into the interstitium of the fallopian tube according to the pressure value, so as to prevent violent insertion by doctors who are inexperienced resulting in damage to the fallopian tubes. Afterwards, theouter sheath 20 and theinner catheter 30 move to the distal end together with theguide wire tip 41 and are inserted into the ostium of the fallopian tube, as shown in FIG. 15 . Then, the sealing and fixingsection 21 at the distal end of theouter sheath 20 expands, as shown in FIG. It also seals the ostium of the fallopian tubes and isolates the pressure transmission between the uterine cavity and the fallopian tubes. Finally, the pressuresensing guide wire 40 is retracted into theinner catheter 30 toward the proximal end, then the distal end of theinner catheter 30 and theguide wire tip 41 are located in theouter sheath 20, as shown in FIG. 17; thecontroller 10 drives The flow pump 70 runs, the liquid-throughtube 60 introduces the medicinal liquid, and the medicinal liquid flows into the fallopian tube through the liquid-throughchamber 31 of theinner catheter 30, the first liquid-throughhole 32 of theinner catheter 30, and the distal through-hole 22 of theouter sheath 20 to control Thedevice 10 obtains the liquid flow n fed back by theflow pump 70 and the liquid pressure P fed back by thepressure sensor 50, and displays the relationship curve between the liquid flow n and the liquid pressure P on thestatus indication panel 80 in real time. The relationship curve between n and liquid pressure P can be used to determine the status of the fallopian tubes, such as unobstructed, unobstructed, blocked, and effusion.

输卵管诊断疏通装置用于疏通输卵管的操作如下：首先，如图19所示，使压力传感导丝40朝向远端前移，使内导管30朝向远端前移，则内导管30顶开外鞘20的远端通孔22后伸出至外鞘20外，导丝头端41通过内导管30的第一通液孔32后伸出至内导管30外。控制器10将压力传感器50实时反馈的压力值与内导管30和压力传感导丝40前移距离L之间的关系曲线图显示在状态指示面板80上，显示输卵管的疏通状态信息，如图20所示，医生由此判断内导管30和导丝头端41通过了输卵管内的阻塞物。之后，使压力传感导丝40朝向近端退移至内导管30中，如图21所示。最后，控制器10驱动流量泵70运转，重新进行通液，由此疏通输卵管。The operation of the fallopian tube diagnosis and dredging device for dredging the fallopian tubes is as follows: first, as shown in Figure 19, the pressuresensing guide wire 40 is moved forward toward the distal end, and theinner catheter 30 is moved forward toward the distal end, and theinner catheter 30 pushes away the outer sheath The distal throughhole 22 of theguide wire 20 protrudes out of theouter sheath 20 , and theguide wire tip 41 protrudes out of theinner catheter 30 after passing through the firstliquid hole 32 of theinner catheter 30 . Thecontroller 10 displays the relationship graph between the pressure value fed back by thepressure sensor 50 in real time and the forward distance L of theinner catheter 30 and the pressure-sensing guide wire 40 on thestatus indication panel 80, and displays information on the unblocking status of the fallopian tubes, as shown in the figure As shown in 20, the doctor judges that theinner catheter 30 and theguide wire tip 41 have passed the obstruction in the fallopian tube. Thereafter, thepressure sensing guidewire 40 is retracted proximally into theinner catheter 30, as shown in FIG. 21 . Finally, thecontroller 10 drives theflow pump 70 to run, and re-through the fluid, thereby dredging the fallopian tubes.

因此，本申请涉及的输卵管诊断疏通装置既能用于诊断输卵管是否通畅，又能用于疏通输卵管；在输卵管诊断疏通装置插入输卵管时，医生根据状态指示面板80上所显示的压力传感器50反馈的压力值来找出最佳的插入角度，防止操作者经验不足暴力插入输卵管而导致损伤输卵管，不易损伤输卵管口部；在诊断过程中，医生根据状态指示面板80上显示的通液流量n和液体压力P的关系曲线图判断输卵管的通畅、通而不畅、阻塞、积液等状态，有效提高输卵管诊断的准确度，也可以得到更具体的诊疗结果。Therefore, the device for diagnosing and dredging the fallopian tubes involved in the present application can be used for diagnosing whether the fallopian tubes are unobstructed, and can be used for dredging the fallopian tubes; Pressure value to find out the best insertion angle, prevent the operator from inexperienced violently inserting the fallopian tube and cause damage to the fallopian tube, and not easy to damage the fallopian tube mouth; The relationship curve of pressure P can judge the patency, patency, blockage, fluid accumulation and other states of the fallopian tube, which can effectively improve the accuracy of fallopian tube diagnosis and obtain more specific diagnosis and treatment results.

进一步地，如图3所示，内导管30的远端还开设有数个分布在通液腔31外周侧的第二通液孔33，通液腔31和内导管30的外界通过第二通液孔33连通。如此，在疏通输卵管的过程中，如图23所示，内导管30通过第二通液孔33输出均匀的液体压力，使得内导管30可以随着输卵管内部结构前移或后腿，且内导管30在前后移动的过程中，经第二通液孔33输出的药液会在内导管30和输卵管之间形成液体保护层，保护输卵管不被穿破。Further, as shown in FIG. 3 , the distal end of theinner catheter 30 is also provided with several second liquid holes 33 distributed on the outer peripheral side of theliquid chamber 31 , and the outside of theliquid chamber 31 and theinner catheter 30 pass through the second liquid hole. Thehole 33 communicates. In this way, in the process of dredging the fallopian tubes, as shown in Figure 23, theinner catheter 30 outputs a uniform liquid pressure through the secondliquid hole 33, so that theinner catheter 30 can move forward or backward with the internal structure of the fallopian tube, and the inner catheter In the process of the 30 moving back and forth, the medicinal liquid output through the secondliquid hole 33 will form a liquid protective layer between theinner catheter 30 and the fallopian tube to protect the fallopian tube from being broken.

进一步地，外鞘20的优选结构为：如图4至图7所示，外鞘20远端的密封固定段21包括褶皱部211、分布在褶皱部211近端侧的气囊部212、以及分隔在褶皱部211和气囊部212之间的封堵部213，封堵部213为气囊部212的部分薄壁；本实施例中，褶皱部211有两个、轴向排布，远端侧的褶皱部211的远端延伸至外鞘20的远端；或者说，褶皱部211的远端端面构成了外鞘20的远端端面。当内导管30的远端被收拢在外鞘20中时，如图3所示，褶皱部211分布在内导管30远端的外周侧，褶皱部211的内周空腔与第二通液孔33连通，褶皱部211的远端还与内导管30的远端密封配合。在外鞘20插入输卵管的过程中，褶皱部211处于缩起的状态，故褶皱部211能够被折叠，便于褶皱部211的插入，同时还减少对输卵管的损伤。之后，在宫腔镜下观察到褶皱部211均置入输卵管口部后再通液，通液腔31中的药液会通过第二通液孔33流入至褶皱部211的内周空腔中，驱使褶皱部211胀起，进而将外鞘20的远端固定于输卵管间质部；之后，再向气囊部212中通气，驱使气囊部212胀起，用以密封输卵管口部并隔绝宫腔与输卵管之间的压力传递，则在后续诊断和疏通过程中能够确保压力传感导丝40更加精准的传导力，排除外界干扰。Further, the preferred structure of theouter sheath 20 is as follows: as shown in FIGS. The blockingportion 213 between the foldedportion 211 and theair bag portion 212, the blockingportion 213 is a part of the thin wall of theair bag portion 212; in this embodiment, there are two foldedportions 211 arranged axially, The distal end of the foldedportion 211 extends to the distal end of theouter sheath 20 ; in other words, the distal end surface of the foldedportion 211 constitutes the distal end surface of theouter sheath 20 . When the distal end of theinner catheter 30 is folded in theouter sheath 20, as shown in FIG. In communication, the distal end of the foldedportion 211 is also sealingly engaged with the distal end of theinner catheter 30 . When theouter sheath 20 is inserted into the fallopian tube, the foldedportion 211 is in a retracted state, so the foldedportion 211 can be folded, which facilitates the insertion of the foldedportion 211 and reduces damage to the fallopian tube. Afterwards, under the hysteroscope, it is observed that thefolds 211 are all placed in the ostium of the fallopian tube and then the liquid is passed through, and the medicinal liquid in theliquid passage cavity 31 will flow into the inner peripheral cavity of thefolds 211 through the secondliquid passage hole 33 , to drive thefolds 211 to expand, and then fix the distal end of theouter sheath 20 to the interstitium of the fallopian tube; then, ventilate theair bag 212 to drive theair bag 212 to seal the ostium of the fallopian tube and isolate the uterine cavity The pressure transmission between the fallopian tube can ensure more accurate transmission force of the pressuresensing guide wire 40 in the subsequent diagnosis and dredging process, and eliminate external interference.

Specifically, when the flow pump 70 runs through the fluid to drive the foldedportion 211 to expand, the blockingportion 213 can conduct pressure, and thepressure gauge 130 obtains the liquid pressure in the inner peripheral cavity of the foldedportion 211 at this time. When the liquid pressure reaches After setting the value, thecontroller 10 controls theflow pump 70 to stop automatically to prevent excessive discomfort of the patient; after that, thecontroller 10 sends an instruction to thesolenoid valve 110, so that thepressure regulating valve 120 increases the pressure value, driving theairbag part 212 to expand, and the pressure Themeter 130 obtains the gas pressure in thevent chamber 23 and theairbag part 212 at this moment, and when the gas pressure reaches the set value, thecontroller 10 controls thesolenoid valve 110 to switch to the pressure maintaining state, and stops inflating theairbag part 212. In addition, after the fallopian tube diagnosis and dredging device is energized, thecontroller 10 will open theelectromagnetic valve 110 in advance, and set thepressure regulating valve 120 to a lower pressure, so that there is a certain pressure in theventilation cavity 23 and theair bag part 212 of theouter sheath 20, so that Theouter sheath 20 can maintain moderate rigidity, and can be placed into the mechanical channel of the hysteroscope more easily and smoothly.

Power on the fallopian tube diagnosis and dredging device, thecontroller 10 opens thesolenoid valve 110 in advance, and sets thepressure regulating valve 120 to a lower pressure, so that there is a certain pressure in theventilation cavity 23 and theair bag part 212 of theouter sheath 20, and theouter sheath 20 Maintain moderate rigidity into the instrument channel of the hysteroscope.

A2、将压力传感导丝40预装在内导管30中，将内导管30预装在外鞘20中，且压力传感导丝40的远端和内导管30的远端都位于外鞘20中。内导管30和压力传感导丝40随外鞘20穿在宫腔镜的机械通道中进入子宫，并在宫腔镜下找到输卵管口部。医生按下操作手柄140上的导丝探测按钮，控制器10控制第二驱动单元160动作，将压力传感导丝40的导丝头端41向前推出至外鞘20外，如图15所示；导丝头端41在宫腔镜下插入输卵管间质部，状态指示面板80显示压力传感器50实时反馈的压力值，医生根据压力值大小找出导丝头端41插入输卵管间质部的最佳插入角度，防止医生经验不足暴力插入而导致损伤输卵管。A2, thepressure sensing guidewire 40 is preinstalled in theinner catheter 30, theinner catheter 30 is preinstalled in theouter sheath 20, and the distal end of thepressure sensing guidewire 40 and the distal end of theinner catheter 30 are located in theouter sheath 20 middle. Theinner catheter 30 and the pressuresensing guide wire 40 are passed through the mechanical channel of the hysteroscope along with theouter sheath 20 to enter the uterus, and the ostium of the fallopian tube is found under the hysteroscope. The doctor presses the guidewire detection button on theoperating handle 140, and thecontroller 10 controls thesecond drive unit 160 to move and push theguidewire tip 41 of thepressure sensing guidewire 40 out of theouter sheath 20, as shown in Figure 15 Theguide wire tip 41 is inserted into the interstitial part of the fallopian tube under the hysteroscope, and thestatus indicator panel 80 displays the pressure value fed back by thepressure sensor 50 in real time. The doctor finds out the position of theguide wire tip 41 inserted into the interstitial part of the fallopian tube according to the pressure value. The best insertion angle prevents the fallopian tube from being damaged due to violent insertion by inexperienced doctors.

A3、外鞘20和内导管30一起随导丝头端41前移置入输卵管口部，在宫腔镜下观察褶皱部211都置入输卵管口部后，医生按下操作手柄140上的通液探测按钮。控制器10控制流量泵70运转，流量泵70将药液源180中的药液经通液管60流入内导管30的通液腔31中，药液经内导管30的第二通液孔33流入至褶皱部211的内周空腔中，如图16所示，褶皱部211胀起，将外鞘20的远端固定于输卵管间质部；此过程中，褶皱部211和气囊部212之间较薄的封堵部213传导压力，压力计130获得褶皱部211的内周空腔中的液体压力，当该液体压力达到设定值后，控制器10控制流量泵70自动停止，防止患者过度不适；并且，第一密封锥面25和第二密封锥面34始终面接触配合，导丝头端41与第一通液孔32的孔壁之间也密封，故药液不会流出至外鞘20的外部。流量泵70停止后，控制器10向电磁阀110发送指令，使得调压阀120升高压力值，向气囊部212中充气，气囊部212胀起；此过程中，压力计130获得通气腔23和气囊部212中的气体压力，当该气体压力达到设定值后，控制器10控制电磁阀110切换为保压状态，则胀起的气囊部212封堵在输卵管口部处，隔绝宫腔与输卵管之间的压力传递。A3. Theouter sheath 20 and theinner catheter 30 are moved forward together with theguide wire tip 41 and inserted into the ostium of the fallopian tube. After observing that thefolds 211 have been inserted into the ostium of the fallopian tube under the hysteroscope, the doctor presses the button on theoperating handle 140. Liquid detection button. Thecontroller 10 controls the operation of theflow pump 70, and theflow pump 70 flows the medicinal liquid in the medicinalliquid source 180 into theliquid passage cavity 31 of theinner catheter 30 through theliquid passage 60, and the medicinal liquid passes through the secondliquid passage hole 33 of theinner catheter 30 Flow into the inner peripheral cavity of the foldedpart 211, as shown in Figure 16, the foldedpart 211 expands, and the distal end of theouter sheath 20 is fixed to the interstitium of the fallopian tube; during this process, the foldedpart 211 and theballoon part 212 Thethinner blocking part 213 between them conducts pressure, and thepressure gauge 130 obtains the liquid pressure in the inner peripheral cavity of the foldedpart 211. When the liquid pressure reaches the set value, thecontroller 10 controls theflow pump 70 to stop automatically to prevent the patient from Excessive discomfort; and, the first sealingcone surface 25 and the secondsealing cone surface 34 are always in contact with each other, and the guidewire head end 41 is also sealed between the hole wall of the firstliquid hole 32, so the liquid medicine will not flow out to the The exterior of theouter sheath 20 . After theflow pump 70 stops, thecontroller 10 sends an instruction to thesolenoid valve 110, so that thepressure regulating valve 120 increases the pressure value, inflates theair bag part 212, and theair bag part 212 expands; during this process, thepressure gauge 130 obtains theventilation cavity 23 and the gas pressure in theair bag part 212, when the gas pressure reaches the set value, thecontroller 10 controls thesolenoid valve 110 to switch to the pressure-holding state, and the expandedair bag part 212 is blocked at the mouth of the fallopian tube, isolating the uterine cavity Pressure transmission with the fallopian tubes.

A4、控制器10控制第二驱动单元160再动作，将压力传感导丝40的导丝头端41向后回退至内导管30中，如图17所示；之后，控制器10控制流量泵70运转，流量泵70按设定值泵入药液，药液通过内导管30的第一通液孔32和外鞘20的远端通孔22流入输卵管，进行输卵管的状态诊断。A4. Thecontroller 10 controls thesecond driving unit 160 to move again, and retracts theguide wire tip 41 of the pressuresensing guide wire 40 back into theinner catheter 30, as shown in FIG. 17; after that, thecontroller 10 controls the flow rate Thepump 70 runs, theflow pump 70 pumps the medicinal solution according to the set value, and the medicinal solution flows into the fallopian tube through the firstliquid hole 32 of theinner catheter 30 and the distal throughhole 22 of theouter sheath 20 to diagnose the state of the fallopian tube.

A5、控制器10中预存有液体压力阈值Px；控制器10获取流量泵70反馈的通液流量n和压力传感器50反馈的液体压力P，并将通液流量n和液体压力P的关系曲线图实时显示在状态指示面板80上，医生根据通液流量n和液体压力P的关系曲线图判断输卵管的通畅、通而不畅、阻塞、积液等状态。A5. The liquid pressure threshold Px is pre-stored in thecontroller 10; thecontroller 10 acquires the liquid flow rate n fed back by theflow pump 70 and the liquid pressure P fed back by thepressure sensor 50, and draws the relationship between the liquid flow rate n and the liquid pressure P The real-time display is displayed on thestatus indication panel 80, and the doctor judges the status of the fallopian tubes according to the relational graph of the fluid flow rate n and the fluid pressure P, such as patency, blockage, effusion, etc.

当状态指示面板80上显示的n-P关系曲线图如图18a所示时，表明压力传感器50反馈的液体压力P恒定且始终小于液体压力阈值Px，则说明输卵管畅通，在通液流量n达到设定值后停止泵入药液。When the n-P relationship graph displayed on thestatus indicator panel 80 is as shown in Figure 18a, it indicates that the liquid pressure P fed back by thepressure sensor 50 is constant and always less than the liquid pressure threshold Px, indicating that the fallopian tubes are unblocked, and when the liquid flow rate n reaches the setting After the value is reached, stop pumping the liquid medicine.

当状态指示面板80上显示的n-P关系曲线图如图18b所示时，表明压力传感器50反馈的液体压力P先逐渐增加、后逐渐减小至恒定值，但压力传感器50反馈的液体压力P始终小于液体压力阈值Px，则说明输卵管通而不畅，需要后续内导管30的疏通。When the n-P relationship graph displayed on thestatus indicator panel 80 is as shown in Figure 18b, it shows that the liquid pressure P fed back by thepressure sensor 50 first gradually increases and then gradually decreases to a constant value, but the liquid pressure P fed back by thepressure sensor 50 is always If it is less than the liquid pressure threshold Px, it means that the fallopian tube is unblocked, and subsequent dredging of theinner catheter 30 is required.

当状态指示面板80上显示的n-P关系曲线图如图18c所示时，表明压力传感器50反馈的液体压力P一直在逐渐增加、并大于液体压力阈值Px，则说明输卵管堵塞，此时，控制器10控制流量泵70自动停止，需要后续内导管30的疏通。When the n-P relationship graph displayed on thestatus indicator panel 80 is as shown in Figure 18c, it indicates that the liquid pressure P fed back by thepressure sensor 50 has been gradually increasing and is greater than the liquid pressure threshold Px, indicating that the fallopian tube is blocked. At this time, thecontroller 10 controls theflow pump 70 to stop automatically, and needs subsequent dredging of theinner conduit 30.

当状态指示面板80上显示的n-P关系曲线图如图18d所示时，表明压力传感器50反馈的液体压力P先逐渐增加、后逐渐减小至恒定值、但突然急剧增加至大于液体压力阈值Px，则说明输卵管存在积液等病变，此时，控制器10控制流量泵70自动停止，需要后续结合腹腔镜进行手术诊断。When the n-P relationship graph displayed on thestatus indication panel 80 is as shown in Figure 18d, it indicates that the liquid pressure P fed back by thepressure sensor 50 first gradually increases, then gradually decreases to a constant value, but suddenly increases sharply to be greater than the liquid pressure threshold Px , it means that there are lesions such as effusion in the fallopian tube. At this time, thecontroller 10 controls theflow pump 70 to stop automatically, and a follow-up surgical diagnosis combined with laparoscopy is required.

针对图18b和图18c所示的情况，医生按下操作手柄140上的自动疏通按钮，则具有上述结构的输卵管诊断疏通装置用于疏通输卵管的使用方法，包括以下步骤：For the situation shown in Figure 18b and Figure 18c, the doctor presses the automatic dredging button on theoperating handle 140, and the method of using the fallopian tube diagnostic dredging device with the above structure for dredging the fallopian tubes includes the following steps:

B1、控制器10控制第一驱动单元150和第二驱动单元160动作，使压力传感导丝40朝向远端前移，使内导管30朝向远端前移，如图19所示，内导管30顶开外鞘20的远端通孔22后伸出至外鞘20外，导丝头端41通过内导管30的第一通液孔32后伸出至内导管30外。B1. Thecontroller 10 controls the action of thefirst drive unit 150 and thesecond drive unit 160, so that the pressuresensing guide wire 40 moves forward toward the distal end, and theinner catheter 30 moves forward toward the distal end. As shown in FIG. 19 , theinner catheter 30 pushes away the distal throughhole 22 of theouter sheath 20 and protrudes out of theouter sheath 20 , and theguide wire tip 41 protrudes out of theinner catheter 30 after passing through the firstliquid hole 32 of theinner catheter 30 .

B2、控制器10将内导管30和压力传感导丝40的前移距离L和压力传感器50反馈的液体压力P的关系曲线图显示在状态指示面板80上。当状态指示面板80上显示的L-P关系曲线图如图20所示时，表明压力传感器50反馈的液体压力P先从恒定值逐渐增加至第一压力记忆点P1、再从第一压力记忆点P1逐渐减小至恒定值，也就表明内导管30的远端和导丝头端41通过了阻塞物。同时，控制器10自动获取第一距离记忆点L1和第二距离记忆点L2，第一距离记忆点L1对应液体压力P从恒定值开始增加的前移距离，第二距离记忆点L2对应液体压力P减小至恒定值的前移距离。B2. Thecontroller 10 displays on the status indication panel 80 a relationship graph between the forward distance L of theinner catheter 30 and thepressure sensing guidewire 40 and the liquid pressure P fed back by thepressure sensor 50 . When the L-P relationship graph displayed on thestatus indicator panel 80 is as shown in Figure 20, it indicates that the liquid pressure P fed back by thepressure sensor 50 first gradually increases from a constant value to the first pressure memory point P1, and then from the first pressure memory point P1 Gradually decreasing to a constant value also indicates that the distal end of theinner catheter 30 and theguide wire tip 41 have passed the obstruction. At the same time, thecontroller 10 automatically acquires the first distance memory point L1 and the second distance memory point L2. The first distance memory point L1 corresponds to the forward distance that the liquid pressure P increases from a constant value, and the second distance memory point L2 corresponds to the liquid pressure. The forward distance that P decreases to a constant value.

B3、控制器10控制第二驱动单元160再动作，将压力传感导丝40的导丝头端41向后回退至内导管30中，如图21所示；控制器10控制流量泵70运转，重新进行通液，药液经内导管30的通液腔31、第一通液孔32和第二通液孔33流至输卵管中。若状态指示面板80上显示的n-P关系曲线图如图18a所示，则疏通成功，表明阻塞物被内导管30和压力传感导丝40成功分离，如图21所示。若状态指示面板80上显示的n-P关系曲线图如图18b所示，则执行下述步骤B4。B3. Thecontroller 10 controls thesecond driving unit 160 to act again, and retracts theguide wire tip 41 of the pressuresensing guide wire 40 back into theinner catheter 30, as shown in FIG. 21 ; thecontroller 10 controls theflow pump 70 After running, the liquid is passed again, and the medicinal liquid flows into the fallopian tube through theliquid passage chamber 31, the firstliquid passage hole 32 and the secondliquid passage hole 33 of theinner catheter 30. If the n-P relationship graph displayed on thestatus indicator panel 80 is as shown in FIG. 18 a , the unblocking is successful, indicating that the obstruction is successfully separated by theinner catheter 30 and the pressuresensing guide wire 40 , as shown in FIG. 21 . If the n-P relationship graph displayed on thestatus indication panel 80 is as shown in FIG. 18 b , the following step B4 is performed.

B4、控制器10向第一驱动单元150和第二驱动单元160发送指令，使内导管30和压力传感导丝40各自回退至第一距离记忆点L1，之后，第一驱动单元150驱动内导管30转动、以及在第一距离记忆点L1和第二距离记忆点L2之间往复移动，第一驱动单元150驱动压力传感导丝40转动、以及在第一距离记忆点L1和第二距离记忆点L2之间往复移动，获取到第二次操作时的第二压力记忆点P2、以及第三次操作时的第三压力记忆点P3，如图22所示，压力记忆点对应的液体压力随着操作次数的增加会下降，当第N次操作时的压力记忆点对应的液体压力相较于第一压力记忆点P1下降超过50％后，再进行通液测试；如此反复操作，直至状态指示面板80上显示如图18a所示的n-P关系曲线图。疏通过程中，如图23所示，经内导管30的第二通液孔33输出的药液会在内导管30和输卵管之间形成液体保护层，保护输卵管不被穿破。B4. Thecontroller 10 sends instructions to thefirst driving unit 150 and thesecond driving unit 160, so that theinner catheter 30 and the pressuresensing guide wire 40 are each retracted to the first distance memory point L1, and then thefirst driving unit 150 drives Theinner catheter 30 rotates and reciprocates between the first distance memory point L1 and the second distance memory point L2, thefirst driving unit 150 drives the pressure sensing guidewire 40 to rotate, and moves between the first distance memory point L1 and the second distance memory point L1. Move back and forth between the distance memory point L2 to obtain the second pressure memory point P2 during the second operation and the third pressure memory point P3 during the third operation. As shown in Figure 22, the liquid corresponding to the pressure memory point The pressure will decrease with the increase of the number of operations. When the liquid pressure corresponding to the pressure memory point during the Nth operation drops by more than 50% compared with the first pressure memory point P1, then perform the liquid test; repeat the operation until The n-P relationship graph shown in FIG. 18a is displayed on thestatus indicating panel 80 . During the dredging process, as shown in FIG. 23 , the medicinal liquid output through the secondliquid hole 33 of theinner catheter 30 will form a liquid protective layer between theinner catheter 30 and the fallopian tubes to protect the fallopian tubes from being broken.

B5、在疏通成功或其他已显示的不再适宜进行介入疏通的情况下，医生按下操作手柄140上的结束按钮，第一驱动单元150驱动内导管30回退，第二驱动单元160驱动压力传感导丝40回退。回退至输卵管口部时，控制器10控制流量泵70反转，对通液腔31进行泄压，随即褶皱部211泄压，取消外鞘20在输卵管给口部的固定；同时，电磁阀110泄压，取消气囊部212的胀起，当压力计130度数值降到预设值后，状态指示面板80提示泄压完成，医生在宫腔镜下进行另一侧输卵管的疏通或取出装置结束手术。B5. In the case of successful dredging or other displayed situations where it is no longer suitable to perform interventional dredging, the doctor presses the end button on theoperating handle 140, thefirst drive unit 150 drives theinner catheter 30 back, and thesecond drive unit 160 drives the pressure The sensing guidewire 40 is retracted. When returning to the ostium of the fallopian tube, thecontroller 10 controls theflow pump 70 to reverse to release the pressure of theliquid cavity 31, and then thefold 211 releases the pressure, canceling the fixing of theouter sheath 20 at the ostium of the fallopian tube; at the same time, thesolenoid valve 110 pressure relief, cancel the expansion of theair bag part 212, when the value of thepressure gauge 130 degrees drops to the preset value, thestatus indicator panel 80 indicates that the pressure relief is complete, and the doctor will dredge the other side of the fallopian tube or take out the device under the hysteroscope End the operation.
