一种一次性收拾网篮A disposable cleaning basket

技术领域technical field

本发明涉及医疗器械技术领域，尤其是一种一次性收拾网篮。The invention relates to the technical field of medical devices, in particular to a disposable cleaning basket.

背景技术Background technique

众所周知，随着内镜技术发展，使用内镜（或称内窥镜）的手术日益增多。特别是在进行内镜下止血术时，胃肠腔内会经常遇到大量血块，血块的出现阻碍了血灶（出血点）的准确定位从而延长手术时间和增大手术难度。胃肠镜（内镜的一种）活检孔道最大直径2.8mm，血块如果较大而且质地脆，无法通过活检孔道，并且在抽吸血液过程中血块堵塞活检孔及遮挡视野，手术医生必须反复进出内镜清理血块，由于血块质脆，常常无法一次性顺利拖出。因无法拖出的血块导致术野（内窥镜的视野）被遮挡或清理血块时间较长，进而导致止血术失败。As we all know, with the development of endoscopic technology, the use of endoscopes (or endoscopes) is increasing day by day. Especially during endoscopic hemostasis, a large number of blood clots are often encountered in the gastrointestinal cavity, and the appearance of blood clots hinders the accurate positioning of blood foci (bleeding points), thereby prolonging the operation time and increasing the difficulty of the operation. The maximum diameter of the biopsy hole of a gastroenteroscope (a type of endoscope) is 2.8mm. If the blood clot is large and brittle, it cannot pass through the biopsy hole, and the blood clot blocks the biopsy hole and blocks the field of view during blood aspiration. The surgeon must repeatedly enter and exit. Endoscopic removal of blood clots is often difficult to remove at one time due to the brittleness of blood clots. The operative field (the field of view of the endoscope) is blocked due to the blood clot that cannot be pulled out, or the time to clear the blood clot is long, which leads to the failure of hemostasis.

胃肠道部分腺瘤生长较大时质脆，PEMR术（分次内镜黏膜下剥离术）将肿物分割切除时，肿瘤碎片无法通过活检孔道，并且在抽吸液过程中碎片堵塞活检孔及遮挡视野，手术医生必须反复进出胃肠镜清理碎片，而且碎片质脆，无法顺利拖出（特别是通过肛门括约肌时）。因肿物碎片将术野遮挡或清理肿物碎片时间较长，无法及时完成术中止血，导致手术失败，因此，便延伸出用于拾取异物（血块及肿瘤碎片）的医用网篮。Some adenomas in the gastrointestinal tract are fragile when they grow large. When PEMR (fractionated endoscopic submucosal dissection) removes the tumor, the tumor debris cannot pass through the biopsy hole, and the debris blocks the biopsy hole during fluid aspiration And blocking the field of view, the surgeon must repeatedly go in and out of the gastroenteroscope to clean up the debris, and the debris is brittle and cannot be pulled out smoothly (especially when passing through the anal sphincter). Because the tumor fragments cover the surgical field or clear the tumor fragments for a long time, the intraoperative hemostasis cannot be completed in time, resulting in the failure of the operation. Therefore, a medical mesh basket for picking up foreign bodies (blood clots and tumor fragments) is extended.

胃肠道腺瘤往往是多发的，完成手术后，肿物需要完整带出体外，通过术后病理，明确是否完整切除。当遇到多发肿物切除时，每次进入人体仅能带出1枚肿物，会大大延长手术时间。而且当肿物体积较小，切除后容易隐藏于结肠的皱襞中，如果有医用网篮将其打包，等所有手术完成后，一起带出体外，可以大大缩短手术时间，减低患者手术时麻醉风险。Gastrointestinal adenomas are often multiple. After surgery, the tumor needs to be completely taken out of the body, and it is determined whether it is completely removed through postoperative pathology. When multiple tumors are removed, only one tumor can be brought out each time it enters the human body, which will greatly prolong the operation time. Moreover, when the tumor is small in size, it is easy to hide in the folds of the colon after excision. If there is a medical mesh basket to pack it and take it out of the body after all operations are completed, the operation time can be greatly shortened and the risk of anesthesia during the operation can be reduced. .

目前，现有的网篮大多都是依靠尼龙绳网篮，然后通过内窥镜推送，并在套设住异物后，因网篮与手柄无法分离，需随着内窥镜一同拖出人体，依次也只能拖出一块，对于上述多个异物，耗时费力，而且如果病变在右半结肠，内镜每次进入均要耗时10分钟以上。肠腔有限空间内，出血就会填满肠腔，无法短时间提供足够的术野完成手术。并且，网篮在与钩锁组装时，即送入内窥镜的活检孔道时，还需要进行术前组装，需挨个串连妥当，但是网篮和钩锁之间的连接结构都十分的精细，因此在组装上便会耗费大量的时间，而且对于新手手术医生及其助手有错误释放网篮的可能，这样往往对于时间就是生命的手术来说，便是存在较大的缺陷。At present, most of the existing mesh baskets rely on nylon rope mesh baskets, which are then pushed through the endoscope. After the foreign body is sheathed, the mesh basket and the handle cannot be separated, so they need to be dragged out of the human body along with the endoscope. Only one piece can be pulled out in turn. For the above-mentioned multiple foreign bodies, it is time-consuming and laborious, and if the lesion is in the right colon, it will take more than 10 minutes for the endoscope to enter each time. In the limited space of the intestinal lumen, the bleeding will fill the intestinal lumen, which cannot provide enough surgical field to complete the operation in a short time. In addition, when the basket is assembled with the hook lock, that is, when it is sent into the biopsy hole of the endoscope, it also needs to be assembled before surgery, and it needs to be properly connected one by one, but the connection structure between the basket and the hook lock is very fine. Therefore, it will take a lot of time to assemble, and it is possible for novice surgeons and their assistants to release the basket by mistake, which is often a major defect for operations where time is life.

如图1至图8所示，本实施例提供的一种一次性收拾网篮，包括网篮本体1和网篮鞘管2，网篮本体1收容于网篮鞘管2的末端处，网篮本体1包括篮筐11、活动锁件12和篮网13，篮筐11呈绿色设计，并且篮筐11在活动锁件12的约束下形成大小可调节的第一子篮筐101、第二子篮筐102，篮网13设于第二子篮筐102上，网篮鞘管2内设置有用于顶触活动锁件12的推动管21，所述活动锁件12和推动管21形状相互等同并均为棱边管，网篮鞘管2的末端的内腔形状与活动锁件12和推动管21形状适配，第一子篮筐101连接有牵引丝杆22，牵引丝杆22与第一子篮筐101之间设置有在扭力作用下会发生截断的易断部24，牵引丝杆22位于推动管21的中空腔内，其中，推动管21在网篮鞘管2推动时，推动管21依靠棱边顶触网篮鞘管2的内壁，从而可以有效的检索与网篮鞘管2内壁之间的摩擦力，便于推动管21的活动。As shown in FIGS. 1 to 8 , a disposable cleaning basket provided in this embodiment includes abasket body 1 and abasket sheath 2. Thebasket body 1 is accommodated at the end of thebasket sheath 2, and the net Thebasket body 1 includes abasket 11 , amovable lock 12 and a net 13 . Thebasket 11 is designed in green, and thebasket 11 forms afirst sub-basket 101 , asecond sub-basket 101 , asecond sub-basket 101 and a second adjustable size under the constraint of themovable lock 12 . The sub-basket 102, the net 13 is arranged on thesecond sub-basket 102, thebasket tube 2 is provided with apush tube 21 for pushing against themovable lock 12, and themovable lock 12 and thepush tube 21 are mutually shaped. The shape of the inner cavity of the end of thebasket sheath tube 2 is compatible with the shape of themovable lock 12 and thepush tube 21. Thefirst sub-basket 101 is connected with atraction screw 22, which is connected to the Between thefirst sub-baskets 101, afrangible portion 24 that can be cut off under the action of torsion is arranged, and thetraction screw 22 is located in the hollow cavity of thepush tube 21. The pushingtube 21 touches the inner wall of thebasket sheath tube 2 by means of the edge, so that the friction force between the pushingtube 21 and the inner wall of thebasket sheath tube 2 can be effectively retrieved, and the movement of the pushingtube 21 is facilitated.

本实施例主要依靠网篮本体1在网篮鞘管2的活动来完成对异物100的捕获和打包。This embodiment mainly relies on the movement of thebasket body 1 in thebasket sheath 2 to complete the capture and packing of theforeign object 100 .

为更加方便本领域的技术人员明白，特进行工作操作说明：In order to be more convenient for those skilled in the art to understand, the working instructions are specially carried out:

即在未使用时，网篮本体1全部收容于网篮鞘管2的末端处，然后依靠作用力于牵引丝杆22和推动管21上，使其一同作用下推动网篮本体1，使得网篮本体1的第二子篮筐102置于外部，其中篮筐11由柔性记忆金属制成，篮网13由尼龙绳制成，在第二子篮筐102推出网篮鞘管2后，第二子篮筐102便自动展开，其端口的大小根据第二子篮筐102推出的程度而定，也同样根据病变体（异物）的大小而定需要推出到何种程度，当第二子篮102筐依靠框口套装病变体后，则随后便将推动管21保持不动，然后拉拽牵引丝杆22，使得篮筐11相对活动锁件12进行活动，使第一子篮筐101逐渐变大，而第二子篮筐102逐渐收拢，直至将第二子篮筐102呈现封口的状态。这时，便只需旋转牵引丝杆22，而活动锁件12又为棱边管，使活动锁件12相对网篮鞘管2之间可达到旋转的限定，不会跟随牵引丝杆22而旋转，而易断部24在扭力的作用下，便会进行断裂，这样便达到对打包好的网篮本体1进行分离的作用。其中，当满足易断部进行断裂的力等于或大于使第一子篮筐101进行形变的力时，第一子篮筐101也将进行旋转，但第一子篮筐101旋转与不旋转均不会影响易断部24的断裂，因为有活动锁件12作用于第一子篮筐101和第二子篮筐102之间，这样便不会使牵引丝杆22发生空转。That is, when not in use, thebasket body 1 is all accommodated at the end of thebasket sheath tube 2, and then relies on the force on thetraction screw 22 and thepush tube 21 to push thebasket body 1 together, so that the net Thesecond sub-basket 102 of thebasket body 1 is placed outside, wherein thebasket 11 is made of flexible memory metal, and the net 13 is made of nylon rope. The twosub-baskets 102 are automatically unfolded, and the size of the port is determined according to the degree to which thesecond sub-basket 102 is pushed out, and the degree to which thesecond sub-basket 102 needs to be pushed out is also determined according to the size of the diseased body (foreign body). After thebasket 102 sets the diseased body against the frame mouth, then thepush tube 21 is kept still, and then thetraction screw 22 is pulled to make thebasket 11 move relative to themovable lock 12, so that thefirst sub-basket 101 gradually changes. Thesecond sub-basket 102 is gradually closed until thesecond sub-basket 102 is in a sealed state. At this time, it is only necessary to rotate thetraction screw 22, and themovable lock 12 is an edge tube, so that themovable lock 12 can reach the limit of rotation relative to thebasket sheath 2, and will not follow thetraction screw 22. Rotation, and the easy-breakingportion 24 will be broken under the action of torsion, so as to achieve the effect of separating thepacked basket body 1 . Thefirst sub-basket 101 will also rotate when the force for breaking the frangible portion is equal to or greater than the force for deforming thefirst sub-basket 101, but thefirst sub-basket 101 rotates and does not rotate equally. The breakage of thefrangible portion 24 will not be affected, because themovable locking member 12 acts between thefirst sub-basket 101 and thesecond sub-basket 102, so that thetraction screw 22 will not be idling.

进一步，为防止牵引丝杆22的在未扭断易断部24时，自己发生扭曲变形，故本实施例的牵引丝杆22由至少两根金属丝相互缠绕形成杆身，这样便可以加强牵引丝杆22的杆身强度，并且也可以更好的传递扭力。Further, in order to prevent the self-twisting deformation of the pullingscrew 22 when thefragile portion 24 is not twisted and broken, the pullingscrew 22 of the present embodiment is formed by at least two metal wires intertwined to form a shaft, so that the traction can be strengthened. The strength of the shaft of thelead screw 22 can also better transmit torque.

进一步，针对本实施例的易断部24，其易断部24为医用304不锈钢，在受到切线旋转剪力大于或等于1牛顿发生断裂，而为了达到易断的效果，其可以通过厚度的设计，因为金属在厚度越薄的情况下便可以将其扭断，而需要说明的是，因为网篮本体1在网篮鞘管2中活动阻力较小，因此在推动过程中，便不会造成易断部24断裂的现象。Further, for thefrangible portion 24 of the present embodiment, thefrangible portion 24 is medical 304 stainless steel, which breaks when subjected to a tangential rotational shear force greater than or equal to 1 Newton, and in order to achieve the effect of being easy to break, it can be designed through the thickness of , because the metal can be twisted off when the thickness is thinner, and it should be noted that because the movement resistance of thebasket body 1 in thebasket sheath 2 is small, during the pushing process, it will not cause A phenomenon in which thefrangible portion 24 is broken.

进一步，对于本实施例的活动锁件12的具体结构，则可以采用截面为六边形的活动锁件12和推动管21，且活动锁件12横向设置有两个穿孔121，并依靠穿孔121，活动锁件12穿设于篮筐11上，这样设计不仅可以满足活动锁件12在篮筐11上的来回活动，还可以避免，即使第一子篮筐101发生旋转后，也不会将旋转力传递给第二子篮筐102。Further, for the specific structure of themovable lock 12 in this embodiment, themovable lock 12 and thepush pipe 21 with a hexagonal cross-section can be used, and themovable lock 12 is provided with two through holes 121 transversely, and the through holes 121 rely on themovable lock 12 . , themovable lock 12 is worn on thebasket 11, so the design can not only satisfy the back and forth movement of themovable lock 12 on thebasket 11, but also avoid that even after thefirst sub-basket 101 rotates, it will not The rotational force is transmitted to thesecond sub-basket 102 .

进一步，本实施例的牵引丝杆22与推动管21均有人工操控手柄部3进行完成，因此本实施例的还设置有手柄部3，对于手柄部3的构成，则它还包括手柄部3，手柄部3包括固定柄31、活动柄32以及拉环33，固定柄31和活动柄32均设置有环口33，固定柄31与网篮鞘管2固定连接，推动管21延伸出固定柄31并与活动柄32固定连接，牵引丝杆22穿过活动柄32并与拉环33连接，在人力作用于活动柄32与拉环33上，可使推动管21和牵引丝杆22达到推拉作用，牵引丝杆22还可以相对于活动柄32进行旋转活动，其中，活动柄32与固定柄31之间的初始距离为A，其A的距离大小需等同于牵引丝杆22与推动管21共同向内推动的距离。因此，通过人工操控对应的活动柄32和拉环33便可以满足上述牵引丝杆22和推动管21的操作。Further, both thetraction screw 22 and thepush tube 21 of the present embodiment are completed by manually manipulating thehandle portion 3, so the present embodiment is also provided with ahandle portion 3, and for the structure of thehandle portion 3, it also includes ahandle portion 3. , thehandle part 3 includes a fixedhandle 31, amovable handle 32 and apull ring 33, the fixedhandle 31 and themovable handle 32 are both provided with aring port 33, the fixedhandle 31 is fixedly connected with thebasket sheath 2, and thepush tube 21 extends out of the fixedhandle 31 and is fixedly connected with themovable handle 32, thetraction screw 22 passes through themovable handle 32 and is connected with thepull ring 33, and the manpower acts on themovable handle 32 and thepull ring 33, so that thepush tube 21 and thetraction screw 22 can be pushed and pulled. function, thetraction screw 22 can also rotate relative to themovable handle 32, wherein the initial distance between themovable handle 32 and the fixedhandle 31 is A, and the distance of A needs to be equal to thetraction screw 22 and thepush tube 21. The distance to push inward together. Therefore, the above-mentioned operations of the pullingscrew 22 and the pushingtube 21 can be satisfied by manually manipulating the correspondingmovable handle 32 and thepull ring 33 .

进一步，为防止在推拉牵引丝杆22时，牵引丝杆22发生自转，故本实施例活动柄32上设置有一凹槽35，凹槽35形状与拉环33相互适配，并在拉环33嵌入于凹槽35内后，拉簧33将无法旋转。即在牵引丝杆22和推动管21在同步向内推动时，拉簧33便可以嵌入与凹槽35中，这样便可以限位住拉簧33的自转。Further, in order to prevent thetraction screw 22 from rotating when thetraction screw 22 is pushed and pulled, agroove 35 is provided on themovable handle 32 in this embodiment. After being embedded in thegroove 35, thetension spring 33 cannot rotate. That is, when thetraction screw 22 and thepush tube 21 are pushed inward synchronously, thetension spring 33 can be embedded in thegroove 35, so that the rotation of thetension spring 33 can be limited.

进一步，为方便人员快速识别，固定柄31和活动柄32设置有不同颜色标识，以及活动锁为黄色，使其在NBI下呈现橘红色，方便辨别。Further, in order to facilitate quick identification by personnel, the fixedhandle 31 and themovable handle 32 are provided with different color marks, and the movable lock is yellow, so that it appears orange-red under NBI, which is convenient for identification.
