技术领域technical field
本实用新型涉及医疗器械技术领域，尤其涉及一种腹腔穿刺置管器。The utility model relates to the technical field of medical instruments, in particular to an abdominal cavity puncture tube inserter.
背景技术Background technique
脑积水是神经科常见疾病，是指脑内的脑室系统液体（脑脊液）异常增多。其确切有效的治疗方式是脑室-腹腔分流术、腰大池-腹腔分流术，即皮肤下建立一条管道，把多余的液体分流到腹腔。Hydrocephalus is a common disease in neurology, which refers to an abnormal increase in the fluid in the ventricular system (cerebrospinal fluid) in the brain. The exact and effective treatment methods are ventriculo-peritoneal shunt and lumbar-peritoneal shunt, that is, a tube is established under the skin to divert excess fluid to the abdominal cavity.
目前，脑室-腹腔分流术，和/或腰大池-腹腔分流术中存在如下几个问题：At present, the following problems exist in ventriculo-peritoneal shunt and/or lumbar-peritoneal shunt:
1、分流管腹腔端置入腹腔时一般需开腹手术放置。这种置管方式存在创伤大、手术时间长、术后并发症较多等不足。1. When the abdominal end of the shunt is placed into the abdominal cavity, laparotomy is generally required. This catheterization method has the disadvantages of large trauma, long operation time, and many postoperative complications.
2、腹腔镜辅助下放置分流管腹腔端，能在一定程度上避免传统手术创伤大的缺点。但是，要形成气腹，有多个腹壁小切口，会带来相关风险和并发症。而且，必须首先把分流管腹腔端置入腹腔，再将套管针拔除、并把分流管头端从中穿过留在腹侧，否则套管针无法与分流管脱离，然后分流管头端经腹、胸、颈皮下，送至头部。这一过程限制了手术整体进程，而且无法在术中即刻验证分流管全线放置到位后是否通畅。2. Laparoscope-assisted placement of the abdominal end of the shunt can avoid the disadvantage of large trauma in traditional surgery to a certain extent. However, to create a pneumoperitoneum, there are multiple small incisions in the abdominal wall, with associated risks and complications. Moreover, the abdominal end of the shunt tube must be placed into the abdominal cavity first, then the trocar is pulled out, and the head end of the shunt tube passes through it and left on the ventral side, otherwise the trocar cannot be separated from the shunt tube, and then the head end of the shunt tube is passed through the abdominal cavity. Under the skin of the abdomen, chest, and neck, and sent to the head. This process limits the overall progress of the operation, and it is impossible to verify the patency of the shunt immediately after it is fully placed in place during the operation.
3、腰大池-腹腔分流术是近年新开展的分流手术，因不需要在脑部切口，有其明显的优势。该手术过程中，患者需取屈膝侧卧位。此时患者腹部的皮肤、皮下组织、腹腔内脏器的解剖位置发生改变，操作空间也非常受限，做腹部切口的难度会增加许多。该手术技巧要求高，手术风险增加，而且手术效果难以保证。同样受体位、操作空间影响，此手术方式在腹腔镜下置管操作是无法开展的。3. Lumbar-peritoneal shunt is a newly developed shunt operation in recent years. It has obvious advantages because it does not require incision in the brain. During this procedure, the patient is placed in a supine position with the knees flexed. At this time, the anatomical position of the patient's abdominal skin, subcutaneous tissue, and internal organs changes, and the operating space is also very limited, making abdominal incision much more difficult. This operation requires high skill, increases the risk of operation, and it is difficult to guarantee the effect of the operation. Also affected by the position and operating space, this surgical method cannot be performed under laparoscopic catheterization.

本实用新型具有以下有益效果：The utility model has the following beneficial effects:
本实用新型腹腔穿刺置管器：The utility model abdominal puncture tube inserter:
1、方便快捷。使用该腹腔穿刺置管器，脑室-腹腔分流术以及腰大池-腹腔分流术不再需要传统开腹操作，而仅仅通过非常微创的方式——穿刺、置管，即可达到原先手术目的。手术流程大为简化，手术时间显著缩短，从1小时左右，缩短为3分钟。1. Convenient and quick. Using this paracentesis tube inserter, ventriculoperitoneal shunt and lumbar cisterna-peritoneal shunt no longer need traditional laparotomy, but only through very minimally invasive methods - puncture and catheter placement, the original surgical purpose can be achieved. The operation process is greatly simplified, and the operation time is significantly shortened from about 1 hour to 3 minutes.
2、操作安全。该腹腔穿刺置管器采用钝性分离、穿刺，避免在操作过程中损伤腹壁的血管。2. Safe operation. The abdominal puncture tube inserter adopts blunt separation and puncture to avoid damage to the blood vessels of the abdominal wall during the operation.
3、置管可靠。穿刺腹壁有明显的突破感后，通过观察生理盐水液平面是否下降，来明确判定是否顺利突破腹壁、进入腹腔，既不需直视下打开腹腔、又能准确判断，置管可靠。3. The tube placement is reliable. After the puncture of the abdominal wall has an obvious breakthrough, observe whether the level of the normal saline solution has dropped to clearly determine whether the abdominal wall has been successfully penetrated and entered the abdominal cavity. It is not necessary to open the abdominal cavity under direct vision, but it can also be accurately judged, and the insertion of the catheter is reliable.
4、手术难度低。传统开腹、或采用腹腔镜下置管手术，需多人或者普外科医生配合才能完成。使用该腹腔穿刺置管器，单个医生即可独立操作完成，手术难度降低。4. Low operation difficulty. Traditional laparotomy or laparoscopic tube insertion requires the cooperation of multiple people or general surgeons. Using the paracentesis tube inserter, a single doctor can complete the operation independently, and the operation difficulty is reduced.
5、体位要求低。使用该腹腔穿刺置管器，对病人体位无特殊要求，而且年轻医生也能顺利完成穿刺、置管操作。5. Low postural requirements. Using the abdominal puncture tube inserter, there is no special requirement on the patient's body position, and young doctors can also successfully complete the puncture and tube placement operations.
6、并发症少。由于减少了肠管外露机会，并减少了切口出血渗入腹腔的可能，所以腹腔感染、分流管堵塞及腹壁伤口相关并发症减少。此外，该腹腔穿刺置管器设计为单次使用，更好地做到无菌。6. Fewer complications. Since the opportunity of intestinal tube exposure is reduced and the possibility of incision bleeding into the abdominal cavity is reduced, abdominal infection, shunt blockage and abdominal wall wound-related complications are reduced. In addition, the paracentesis inserter is designed for single use for better sterility.
7、手术更为流畅。分流管全线放置完成，检测脑脊液流出通畅之后，再应用腹腔穿刺置管器，把腹腔端置入腹腔，分流效果更为确切。另外，腹腔端分流管置管前后，不管是插接部件，还是容置部件，都允许原位拆开、分离，而不必移动分流管的任何一端，从而使手术非常流畅。7. The operation is smoother. After the placement of the shunt tube is complete, and the cerebrospinal fluid is detected to flow out smoothly, the abdominal puncture tube inserter is used to place the abdominal end into the abdominal cavity, and the shunt effect is more accurate. In addition, before and after the placement of the shunt at the abdominal cavity, no matter the inserting part or the receiving part, it is allowed to be disassembled and separated in situ without moving any end of the shunt, so that the operation is very smooth.
8、适用性广。不仅仅是脑室-腹腔分流术、腰大池-腹腔分流术，其他各种需要在腹腔内置管外引流、分流的手术，都可以使用腹腔穿刺置管器。8. Wide applicability. Not only ventricle-peritoneal shunt, lumbar-peritoneal shunt, but also various other operations that require external drainage and shunt built in the abdominal cavity, can use the paracentesis catheter inserter.

以下结合附图对本实用新型作进一步详细说明。Below in conjunction with accompanying drawing, the utility model is described in further detail.
如图1-5，本实用新型腹腔穿刺置管器包括插接部件1和容置部件2。所述插接部件1包括盖座11、套管12、锁紧配合结构一13和解锁结构14。所述盖座11表面设有进水口，所述进水口与所述套管12连通，所述套管12可以是部分设于所述盖座11内，自所述盖座11底部向外延伸，或者也可以设于所述盖座11底部，所述套管12经所述盖座11内的通道与所述进水口连通。所述锁紧配合结构一13设于所述盖座11底部两侧，所述解锁结构14设于所述盖座11侧部，并可控制锁紧配合结构一13。所述容置部件2包括卡座21、管针22、锁紧配合结构二（图中未示出）。所述卡座21表面设有容置口23，所述管针22与所述容置口23内部连通，所述管针22可以部分设于所述卡座21内，自所述卡座21底部向外延伸，或者也可以设于所述卡座21底部，所述管针22经所述卡座21内的通道与所述容置口23连通。As shown in Fig. 1-5, the abdominal puncture tube inserter of the present invention includes an inserting part 1 and an accommodating part 2. The plug-in component 1 includes a cover 11 , a sleeve 12 , a first locking structure 13 and an unlocking structure 14 . The surface of the cover seat 11 is provided with a water inlet, and the water inlet communicates with the sleeve 12. The sleeve 12 may be partly arranged in the cover seat 11 and extends outward from the bottom of the cover seat 11. , or it can also be arranged at the bottom of the cover seat 11, and the sleeve 12 communicates with the water inlet through the passage in the cover seat 11. The first locking structure 13 is located on both sides of the bottom of the cover 11 , and the unlocking structure 14 is located on the side of the cover 11 and can control the first locking structure 13 . The accommodating part 2 includes a card seat 21 , a tube pin 22 , and a second locking structure (not shown in the figure). The surface of the card holder 21 is provided with an accommodating opening 23, and the needle 22 communicates with the inside of the accommodating opening 23. The bottom extends outward, or may also be arranged at the bottom of the holder 21 , and the needle 22 communicates with the accommodating opening 23 through a passage in the holder 21 .
所述插接部件1可将其管针22，裸露部分经所述容置部件2的容置口23插入所述盖座11和管针22内。为便于分流管置管且在置管后便于撤离置管器，所述锁紧配合结构一13与所述锁紧配合结构二可相互配合构成锁紧机构，且该锁紧机构至少能实现两级锁紧状态，即在至少一级锁紧状态时，所述管针22与所述套管12两者配合，使得两者末端构成封闭结构，便于腹腔穿刺置管器有效穿刺，且在至少一级不同于上述锁紧状态的锁紧状态时，所述管针22与所述套管12两者配合，使得两者末端构成不封闭结构，所述管针22长于所述套管12，所述套管12至少末端为不封闭结构，所述管针22也为不封闭结构，这样不论是将分流管经置管器插入腹腔还是穿刺结束后退出置管器，也较为便捷，适应不同病患需求。进一步，所述套管12末端设有开口，该开口与套管12内相通，分流管自该开口处伸出，当处于管针22和套管12配合在两者末端为不封闭结构的锁紧状态下时，分流管自所述开口处经该不封闭结构伸入腹腔。所述管针22的针壁处设有纵向开口，该纵向开口自卡座21底部纵向向下开设，在接近所述管针22末端处其开口向针壁处弯曲延伸，该开口在靠近末端处以弧线方式开设，其末端为封闭的针头结构。同时，为了当处于管针22和套管12配合在两者末端为封闭结构的锁紧状态下时，所述套管12具有与管针22相适应的结构，优选为弧形套管，所述套管12在靠近末端处沿管壁向末端以弧线方式逐渐收拢，使得其与管针22配合的部分为弧形管壁，这样不仅封闭严实，同时当处于管针22和套管12配合在两者末端为不封闭结构的锁紧状态下时，两者末端的不封闭结构，弧形套管与纵向开口之间因未封闭产生的开放式空间，因有着弧状结构而能引导分流管向置管器侧边伸出，伸入的分流管以侧向方式进入腹腔，可适于在腹腔内调整分流管的放置位置，同时该开放式空间不是太大，分流管能有效穿入/穿出。如此设计的管针22和套管12可相互配合，其配合处的横截面为封闭横截面（如图4、5），即管针22和套管12配合处的圆周方向互为封闭。图5可见，管针22弧状结构的弧长大于套管12弧状结构的弧长，所述管针22的针壁处设有卡合所述套管11的壁槽。也可以将所述纵向开口开至管针22末端，但有一问题，如此设置的管针22末端过于锋利，且穿刺施力部集中在一侧，无法施力均匀地进行腹腔穿刺，尤其对体位特殊的病患进行穿刺十分不易，效果不优于前述方案。插接部件1和容置部件2相互组合使用，使得进水口、容置口23、套管12、管针22共同构成一条通道，所述通道允许生理盐水、分流管通过。所述进水口口径可比所述容置口23小，仅用于注入生理盐水。而所述容置口23的口径需不小于分流管口径，套管12、管针22配合的结构形成的口径也需不小于分流管口径，以允许分流管穿过。当做脑室-腹腔分流术时，患者取平卧位，腹腔呈水平位，腹腔穿刺置管器呈垂直位。此时从进水口打生理盐水比从容置口23打生理盐水方便，则选择进水口作为生理盐水的注入口。而做腰大池-腹腔分流术时，患者取侧卧位，腹腔呈垂直位，腹腔穿刺置管器呈水平位，此时从容置口打生理盐水比从进水口打生理盐水方便，当此时需要用骨蜡填塞进水口，以防容置口23打水时从进水口溢出，这样就能从容置口打生理盐水。The needle 22 of the plug-in component 1 and the exposed part can be inserted into the cover 11 and the needle 22 through the accommodating opening 23 of the accommodating component 2 . In order to facilitate the placement of the shunt tube and the withdrawal of the tube inserter after the tube is placed, the locking cooperation structure 13 and the locking cooperation structure 2 can cooperate with each other to form a locking mechanism, and the locking mechanism can at least realize two Level locking state, that is, in at least one level locking state, the needle 22 and the cannula 12 cooperate, so that the ends of the two form a closed structure, which is convenient for the effective puncture of the paracentesis tube inserter, and at least In a locked state different from the above-mentioned locked state, the needle 22 cooperates with the sleeve 12 so that the ends of the two form an unclosed structure, the needle 22 is longer than the sleeve 12, At least the end of the cannula 12 is an unclosed structure, and the cannula 22 is also an unclosed structure, so whether the shunt is inserted into the abdominal cavity through the catheter inserter or withdrawn from the catheter inserter after the puncture, it is also relatively convenient and adaptable to different conditions. patient needs. Further, the end of the sleeve 12 is provided with an opening, which communicates with the inside of the sleeve 12, and the shunt tube protrudes from the opening. When the needle 22 and the sleeve 12 are matched at the ends of the two, it is a lock with an unclosed structure. In the tight state, the shunt tube extends into the abdominal cavity from the opening through the non-closed structure. The needle wall of the tube needle 22 is provided with a longitudinal opening, which is opened longitudinally downward from the bottom of the holder 21, and its opening bends toward the needle wall near the end of the tube needle 22, and the opening near the end It is opened in an arc, and its end is a closed needle structure. Simultaneously, in order to be in when the needle 22 and the sleeve pipe 12 are engaged in the locking state in which both ends are closed structures, the sleeve pipe 12 has a structure adapted to the pipe needle 22, preferably an arc sleeve, so The sleeve 12 is close to the end along the tube wall to the end in an arc-shaped manner, so that the part that matches the tube needle 22 is an arc-shaped tube wall, so that it is not only tightly closed, but also when it is between the tube needle 22 and the sleeve tube 12. Cooperate in the locked state where the two ends are unclosed structures, the unclosed structures at the ends of the two ends, the open space between the arc-shaped sleeve and the longitudinal opening due to the unclosed, can guide the shunt due to the arc-shaped structure The tube protrudes to the side of the catheter inserter, and the shunt tube that is inserted enters the abdominal cavity in a lateral manner, which is suitable for adjusting the placement position of the shunt tube in the abdominal cavity. At the same time, the open space is not too large, and the shunt tube can be effectively penetrated / wear out. The needle 22 and the sleeve 12 designed in this way can cooperate with each other, and the cross section of the joint is a closed cross section (as shown in Figures 4 and 5), that is, the circumferential direction of the joint of the needle 22 and the sleeve 12 is mutually closed. It can be seen from FIG. 5 that the arc length of the arc-shaped structure of the needle 22 is longer than that of the arc-shaped structure of the cannula 12 , and the needle wall of the cannula 22 is provided with a wall groove engaging the cannula 11 . It is also possible to open the longitudinal opening to the end of the tube needle 22, but there is a problem that the end of the tube needle 22 set in this way is too sharp, and the puncture force application part is concentrated on one side, and it is impossible to apply force evenly for abdominal puncture, especially for body position. It is very difficult for special patients to perform puncture, and the effect is not better than the above-mentioned scheme. The inserting part 1 and the containing part 2 are used in combination, so that the water inlet, the containing port 23, the cannula 12, and the needle 22 together form a channel, which allows physiological saline and shunt tubes to pass through. The caliber of the water inlet may be smaller than that of the accommodating port 23, and is only used for injecting physiological saline. The caliber of the accommodating port 23 must not be smaller than the caliber of the shunt tube, and the caliber formed by the cooperation of the casing 12 and the needle 22 must also be no smaller than the caliber of the shunt tube, so as to allow the shunt tube to pass through. When performing a ventriculoperitoneal shunt, the patient is placed in a supine position, the abdominal cavity is in a horizontal position, and the paracentesis catheter is in a vertical position. Now it is more convenient to beat normal saline from the water inlet than from the accommodating port 23, so the water inlet is selected as the injection port of the normal saline. When performing a lumbar-peritoneal shunt, the patient is placed in a lateral position, the abdominal cavity is in a vertical position, and the paracentesis catheter is in a horizontal position. At this time, it is more convenient to inject normal saline from the receiving port than from the water inlet. The water inlet needs to be stuffed with bone wax to prevent the accommodating port 23 from overflowing the water inlet when fetching water, so that normal saline can be beaten from the accommodating port.
其中，所述锁紧配合结构一13与所述锁紧配合结构二可相互配合构成锁紧机构。所述锁紧配合结构一13可以为锁扣。所述锁紧配合结构二可以为于锁扣相配合的锁孔，所述锁孔为多层锁孔，如两层锁孔时，设为上锁扣孔和下锁扣孔，这样当锁紧配合结构一13伸入锁紧配合结构二后，可先利用锁扣与上锁扣孔配合构成一级锁紧状态，随着锁紧配合结构一再次伸入，锁扣与下锁扣孔配合构成二级锁紧状态。如需退出锁紧状态，可利用解锁结构14进行。所述解锁结构14包括设于所述盖座11的解锁按钮，以及设于所述盖座11内且与所述锁紧配合结构一13连接的复位部件。所述解锁按钮具有操作部和作用部，所述解锁按钮设于盖座11两侧，其大致形状为三角状，其作用部为斜面。所述复位部件，可以是复位弹簧，其一端设于盖座11内，另一端连接锁紧配合结构一13，当其为锁扣时，所述盖座底部11具有使锁扣贯穿的活动槽，且该锁扣可在活动槽内活动，所述锁扣进一步包括在活动槽上方的受力部和在活动槽下方的动作部，所述受力部面向解锁按钮作用部的一面可以是平面，亦可以是斜面，以确保所述作用部在所述解锁结构未动作状态下与所述锁紧配合结构一具有间隔，以确保无动作，其中斜面优于平面。当解锁结构未动作时，复位弹簧处于自然伸张状态；当用手按捏操作部时，解锁按钮的作用部发生位移，作用部相抵于受力部时，使得与之连接的复位弹簧被压缩，锁扣在活动槽内发生位移，可使锁扣脱离锁扣孔；一旦放手，解锁按钮回归原位，复位弹簧复位使得锁扣恢复到初始状态。所述盖座11具有所述锁紧配合结构一13脱开或锁入所述锁紧配合结构二的活动槽。Wherein, the first locking cooperation structure 13 and the second locking cooperation structure can cooperate with each other to form a locking mechanism. The locking fit structure one 13 may be a buckle. The second lock fit structure can be a lock hole matched with a lock, and the lock hole is a multi-layer lock hole. For example, when there are two layers of lock holes, it is set as an upper lock hole and a lower lock hole, so that when the lock After the tight fitting structure 13 stretches into the locking fitting structure 2, the lock buckle can be used to cooperate with the upper locking buckle hole to form a first-level locking state. Cooperate to form a secondary locking state. If it is necessary to exit the locked state, the unlocking structure 14 can be used. The unlocking structure 14 includes an unlocking button disposed on the cover base 11 , and a reset component disposed inside the cover base 11 and connected to the first locking engagement structure 13 . The unlock button has an operation part and an action part, and the unlock button is arranged on both sides of the cover 11, and its general shape is triangular, and its action part is a slope. The resetting part can be a resetting spring, one end of which is arranged in the cover seat 11, and the other end is connected to a locking fit structure 13. When it is a lock, the bottom 11 of the cover base has a movable groove through which the lock is inserted. , and the lock can move in the movable groove, the lock further includes a force-bearing part above the movable groove and an action part below the movable groove, and the side of the force-bearing part facing the unlocking button action part can be a plane , It can also be a slope to ensure that the action part has a distance from the locking engagement structure when the unlocking structure is not in action, so as to ensure no action, wherein the slope is better than the plane. When the unlocking structure is not in action, the return spring is in a naturally stretched state; when the operating part is pressed by hand, the action part of the unlock button is displaced, and when the action part is against the force receiving part, the return spring connected to it is compressed, The lock buckle is displaced in the movable groove, which can make the lock buckle break away from the lock buckle hole; once you let go, the unlock button returns to its original position, and the return spring returns to make the lock buckle return to its original state. The cover base 11 has an active groove for the first lock fit structure 13 to disengage or lock into the second lock fit structure.
另外，在所述盖座11、卡座21处分别设有握持部一、握持部二。盖座11处的握持部一为弧形握持部，所述握持部自所述盖座11表面向两侧呈弧状以便于握持，而所述解锁结构14设于盖座11两侧，便于解锁结构14解锁操作。所述卡座21处的握持部二在其盖座11的角边做了圆弧处理。In addition, the first grip part and the second grip part are respectively provided at the cover seat 11 and the card seat 21 . The first holding part at the cover base 11 is an arc-shaped holding part, and the holding part is arc-shaped from the surface of the cover base 11 to both sides for easy gripping, and the unlocking structure 14 is arranged on both sides of the cover base 11. side, which facilitates the unlocking operation of the unlocking structure 14. The handle portion 2 at the card base 21 is treated with arcs at the corners of the cover base 11 .
为了便于观察生理盐水液面、分流管放置情况，所述管针22为透明结构，在其针壁处还设有刻度标记。In order to facilitate the observation of the physiological saline level and the placement of the shunt tube, the tube needle 22 is of a transparent structure, and scale marks are also provided on the needle wall.
在进行腹腔置管时，首先在在脐上正中两横指位置（脐上3厘米），纵行切开一个约0.5cm皮肤切口。利用腹壁固定装置将待切口定位，将插接部件1插入容置部件2。当听到“咔、咔”声响后，说明锁紧机构已完成两级锁定（以两级锁定为例），套管11已与管针22组装固定。此时，根据腹壁固定装置，将腹腔穿刺置管器对准切口进行穿刺。有明显的突破感后停止穿刺，此时需验证穿刺是否成功。按住解锁结构的同时轻轻后拉盖座，使之解退并锁定于上锁扣孔。取5ml生理盐水由进水口12缓缓注入套管内。如若生理盐水由容置口23溢出，则说明尚未突破腹壁，需插回盖座至下锁扣孔，继续穿刺；如若从套管针壁看到生理盐水液面顺利下降，则明确穿刺置管器已顺利突破腹壁、进入腹腔。穿刺腹腔成功，则去除腹壁固定装置。将已连接好脑室端、经皮下隧道到达腹部切口的分流管的腹腔端，或者是将已连接好腰大池置管、经皮下隧道到达腹部切口的分流管的腹腔端，经验证脑脊液分流通畅后，由容置口23缓缓塞入，直到预设长度。最后，一手分流管，一手按住解锁结构的同时轻轻后拉盖座，将插接部件完全退出腹壁；继而再将容置部件缓缓退出腹壁，注意不要将分流管带出。分流管腹腔端置管位置完善后，缝合腹壁皮肤切口（1-2针）。When performing abdominal catheterization, first make a longitudinal skin incision of about 0.5 cm at the position of two transverse fingers in the middle of the umbilical cord (3 cm above the umbilical cord). The incision to be made is positioned using an abdominal wall fixing device, and the insertion part 1 is inserted into the accommodating part 2 . When the sound of "click, click" is heard, it means that the locking mechanism has completed the two-stage locking (take the two-stage locking as an example), and the cannula 11 has been assembled and fixed with the tube needle 22 . At this time, according to the abdominal wall fixation device, align the paracentesis tube inserter with the incision for puncture. Stop the puncture when there is an obvious breakthrough, and it is necessary to verify whether the puncture is successful. While pressing the unlocking structure, gently pull the cover seat back to release it and lock it in the upper lock hole. Take 5ml of physiological saline and slowly inject it into the casing through the water inlet 12 . If the normal saline overflows from the receiving port 23, it means that the abdominal wall has not been broken through, and the cover needs to be inserted back to the lower lock hole to continue puncturing; if the normal saline level drops smoothly from the trocar wall, it is clear to puncture and place the catheter The device has successfully broken through the abdominal wall and entered the abdominal cavity. If the puncture of the abdominal cavity is successful, the abdominal wall fixation device is removed. Connect the abdominal end of the shunt tube that has been connected to the ventricle end and reach the abdominal incision through the subcutaneous tunnel, or the abdominal end of the shunt tube that has been connected to the lumbar pool and reach the abdominal incision through the subcutaneous tunnel. After the smooth flow of the cerebrospinal fluid is verified , slowly inserted through the accommodating port 23 until the preset length. Finally, hold the shunt tube with one hand and gently pull back the cover seat while pressing the unlocking structure with the other hand to completely withdraw the insertion part from the abdominal wall; then slowly withdraw the receiving part from the abdominal wall, taking care not to take the shunt tube out. After the placement of the abdominal end of the shunt tube is completed, the skin incision on the abdominal wall is sutured (1-2 stitches).
