技术领域technical field
本申请属于医疗器械技术领域，尤其涉及一种插入管、对接组件以及内窥镜。The application belongs to the technical field of medical instruments, and in particular relates to an insertion tube, a docking assembly and an endoscope.
背景技术Background technique
内窥镜的插入管的一端连接在内窥镜手柄上的适配器上，以实现插入管与内窥镜手柄的连接固定。由于容置于插入管内的牵引绳需要与位于手柄内的驱动机构连接，而驱动机构位于适配器外。目前，大多数内窥镜是通过在适配器上开设孔道供牵引绳穿出，但是这种方式存在插入管与内窥镜手柄装配效率低的问题。One end of the insertion tube of the endoscope is connected to the adapter on the handle of the endoscope to realize the connection and fixation of the insertion tube and the handle of the endoscope. Because the traction rope accommodated in the insertion tube needs to be connected with the driving mechanism located in the handle, and the driving mechanism is located outside the adapter. At present, most endoscopes are provided with holes on the adapter for the traction rope to pass through, but this method has the problem of low assembly efficiency of the insertion tube and the endoscope handle.

本申请与现有技术相比，具有以下有益效果：Compared with the prior art, the present application has the following beneficial effects:
本申请提供的插入管，通过在管体的近端侧壁上开设引导孔，使引导孔与管体轴向设置的牵引通道相连通，从而使牵引通道的牵引绳能够从引导孔穿出至管体外，实现了牵引绳的提前穿出。从而在插入管与内窥镜手柄装配连接过程中，能够快速的将牵引绳与内窥镜手柄上的驱动机构相连接，而无需将牵引绳再插入适配器中，再从适配器上的开口处穿出后与驱动机构相连接，提高了装配的效率，并且，由于牵引绳不经过适配器直接与驱动机构相连，还能避免牵引绳在移动过程中对适配器造成磨损。在另一方面，由于插入管上本身具有供牵引绳穿过的牵引通道，只需要在管体上开设引导孔即可将将牵引绳的提前引出，从而无需在适配器上专门设置与牵引通道连通的、供牵引绳穿入的孔道和穿出的孔道，从而降低适配器的加工难度。The insertion tube provided by the present application provides a guide hole on the proximal side wall of the tube body, so that the guide hole communicates with the traction channel provided in the axial direction of the tube body, so that the traction rope of the traction channel can pass out from the guide hole to the outside of the tube body, and the early penetration of the traction rope is realized. Therefore, during the assembly and connection process of the insertion tube and the endoscope handle, the traction rope can be quickly connected to the driving mechanism on the endoscope handle without inserting the traction rope into the adapter again, and then passing through the opening on the adapter to be connected to the driving mechanism, which improves the efficiency of assembly, and, since the traction rope is directly connected to the driving mechanism without passing through the adapter, it can also prevent the traction rope from causing wear to the adapter during movement. On the other hand, since the insertion tube itself has a traction channel for the traction rope to pass through, it is only necessary to open a guide hole on the tube body to lead out the traction rope in advance, so that there is no need to specially set holes on the adapter that communicate with the traction channel for the traction rope to penetrate and pass through, thereby reducing the processing difficulty of the adapter.

下面结合附图并参考具体实施例描述本申请：Describe the application below in conjunction with accompanying drawing and with reference to specific embodiment:
如图1所示，本申请提供了一种插入管，该插入管的结构包括管体100，管体100为柔性管体100，管体100具有轴向的近端和远端，管体100的近端用于连接适配器400，管体100的远端则可通过人体的孔道插入人体中。需要提出的是，在本申请的各实施例中，“近端”和“远端”是指内窥镜及其配件在使用环境下，相对于使用者的远近位置而言，其中，距离使用者较近的一端拟定为“近端”，距离使用者较远的一端拟定为“远端”。As shown in FIG. 1 , the present application provides an insertion tube. The structure of the insertion tube includes a tube body 100. The tube body 100 is a flexible tube body 100. The tube body 100 has an axial proximal end and a distal end. The proximal end of the tube body 100 is used to connect to the adapter 400, and the distal end of the tube body 100 can be inserted into the human body through the pores of the human body. It should be pointed out that, in each embodiment of the present application, "proximal end" and "distal end" refer to the far and near positions of the endoscope and its accessories relative to the user in the use environment, wherein the end closer to the user is designated as the "near end", and the end farther away from the user is designated as the "distal end".
管体100内具有沿管体100轴向设置的牵引通道110，牵引通道110用于容纳牵引绳，以对牵引绳起到导向和隔离的作用，一个牵引通道110内可以容纳一根或多根牵引绳。管体100的侧壁开设有引导孔120，并且引导孔120靠近管体100的近端，引导孔120连通管体100外和牵引通道110，从而使牵引绳在牵引通道110内由管体100的远端布置到管体100的近端时，能够穿过设置在侧壁上引导孔120提前到达管体100外，而无需从牵引通道110的近端端部到达管体100外。The pipe body 100 has a traction channel 110 arranged axially along the pipe body 100. The traction channel 110 is used for accommodating a traction rope to guide and isolate the traction rope. One traction channel 110 can accommodate one or more traction ropes. The side wall of the tube body 100 is provided with a guide hole 120, and the guide hole 120 is close to the proximal end of the tube body 100. The guide hole 120 communicates with the outside of the tube body 100 and the traction channel 110, so that when the traction rope is arranged from the distal end of the tube body 100 to the proximal end of the tube body 100 in the traction channel 110, it can pass through the guide hole 120 arranged on the side wall to reach the outside of the tube body 100 in advance without reaching the tube body 1 from the proximal end of the traction channel 110. 00 outside.
需要说明的是，上述的管体100既可以是与插入管中主动弯曲段和/或被动弯曲段相连接管体100结构，也可以是主动弯曲段和/或被动弯曲段的一部分，牵引绳的一端与主动弯曲段相连接，牵引绳的另一端则位牵引通道110内。在管体100靠近近端的侧壁上开设引导孔120连通牵引通道110，一方面，能够使牵引绳从管体100的侧壁提前穿出，而不会从管体100的近端穿出，这样设置，插入管与内窥镜手柄装配连接过程中，能够快速的将牵引绳与内窥镜手柄上的驱动机构相连接，而无需将牵引绳再插入适配器400中，再从适配器400上的开口处穿出后与驱动机构相连接，提高了装配的效率，并且，由于牵引绳不经过适配器400直接与驱动机构相连，还能避免牵引绳在移动过程中对适配器400造成磨损。在另一方面，由于在管体100本身具有供牵引绳穿过的牵引通道110，只需要在管体100的侧壁开设引导孔120即可将牵引绳提前引出，因此，则无需在与插入管连接的适配器400上再开设专门的与牵引丝连通的、供牵引绳穿入的孔道和穿出的孔道，从而简化了适配器400的结构，降低了适配器400的加工难度。It should be noted that the above-mentioned tubular body 100 can be a tubular body 100 structure connected to the active bending section and/or passive bending section in the insertion tube, or can be a part of the active bending section and/or passive bending section. One end of the traction rope is connected to the active bending section, and the other end of the traction rope is located in the traction channel 110. A guide hole 120 is provided on the side wall near the proximal end of the tube body 100 to communicate with the traction channel 110. On the one hand, the traction rope can be passed out from the side wall of the tube body 100 in advance without passing out from the proximal end of the tube body 100. In this way, during the assembly and connection process of the insertion tube and the endoscope handle, the traction rope can be quickly connected to the drive mechanism on the endoscope handle without the need to insert the traction rope into the adapter 400, and then pass through the opening on the adapter 400 to connect with the drive mechanism. The connection improves the assembly efficiency, and since the traction rope is directly connected to the drive mechanism without passing through the adapter 400, it can also prevent the traction rope from causing wear to the adapter 400 during the moving process. On the other hand, since the tube body 100 itself has a traction channel 110 for the traction rope to pass through, only the guide hole 120 needs to be provided on the side wall of the tube body 100 to lead out the traction rope in advance.
进一步的，上述的引导孔120为矩形孔，引导孔120的长度方向沿管体100的轴向布置。需要说明的是，这里所提到的引导孔120的长度方向指的是引导孔120的径向所形成的矩形截面的长度方向。将引导孔120设置为矩形孔，能够增大引导孔120的开孔大小，由于引导孔120的长度方向沿管体100的轴向布置，因此，引导孔120的长度方向是与牵引通道110的方向以及牵引通道110内牵引绳的长度方向平行的，由此可以更方便的将牵引绳从引导孔120内穿出。牵引绳穿出引导孔120的方式可以通过专门的勾绳件从引导孔120件牵引绳勾出，或者利用牵引绳的可弯曲性能，通过转动牵引绳使牵引绳的端部进入引导孔120中穿出。Further, the above-mentioned guide hole 120 is a rectangular hole, and the length direction of the guide hole 120 is arranged along the axial direction of the pipe body 100 . It should be noted that the length direction of the guide hole 120 mentioned here refers to the length direction of the rectangular section formed by the radial direction of the guide hole 120 . Setting the guide hole 120 as a rectangular hole can increase the opening size of the guide hole 120. Since the length direction of the guide hole 120 is arranged along the axial direction of the pipe body 100, the length direction of the guide hole 120 is parallel to the direction of the traction passage 110 and the length direction of the traction rope in the traction passage 110, so that the traction rope can be passed through the guide hole 120 more conveniently. The way that the traction rope passes through the guide hole 120 can be hooked out from the guide hole 120 by a special rope hook, or by using the bendability of the traction rope, the end of the traction rope can be passed through the guide hole 120 by rotating the traction rope.
如图2所示，可选的，上述的引导孔120长度方向的一侧与管体100的近端端面连通，以使引导孔120的一侧在管体100的近端形成开口121，并且，牵引通道110的一端也与管体100的近端端面连通，以使引导孔120将牵引通道110从管体100的近端端面切开一定长度的缝隙。在将牵引绳引出时，则能够将牵引绳从管体100的近端的开口121穿出至管体100的侧壁，从而更加方便的使牵引绳从管体100穿出的位置位于管体100的侧壁。而且，通过这种结构在穿出牵引绳的过程中也无需其他的勾绳件等辅助装置。As shown in FIG. 2 , optionally, one side of the above-mentioned guide hole 120 in the length direction communicates with the proximal end face of the tubular body 100, so that one side of the guide hole 120 forms an opening 121 at the proximal end face of the tubular body 100, and one end of the traction channel 110 is also communicated with the proximal end face of the tubular body 100, so that the guide hole 120 cuts the traction channel 110 from the proximal end face of the tubular body 100 to a certain length of slit. When the traction rope is drawn out, the traction rope can be passed through the opening 121 at the proximal end of the tubular body 100 to the side wall of the tubular body 100 , so that the position where the traction cord passes through the tubular body 100 is located on the sidewall of the tubular body 100 more conveniently. Moreover, through this structure, there is no need for other auxiliary devices such as hooking parts in the process of passing out the pulling rope.
进一步的，如图3所示，上述的插入管还包括固定在管体100上的导向管200，导向管200至少一部分位于插入管外，导向管200的一端与引导孔120连通，导向管200的另一端则位于管体100外，牵引绳在牵引通道110内穿过导向管200后到达管体100外。在一方面，由于牵引绳的直径很小，属于细线，牵引绳由牵引通道110到达管体100外会发生弯曲，因此，牵引绳的弯曲部位在移动过程中会对弯曲部位所接触到的引导孔120孔壁不断的切割，容易导致牵引孔变形、管体100损坏，对此，设置导向管200能够将牵引绳与引导孔120隔离，从而避免牵引孔变形和管体100损坏，优选的，导向管200采用高耐磨性能的材料制成，例如钢铁、陶瓷等，以使导向管200的耐磨性能高于管体100的耐磨性能。在另一方面，设置导向管200之后，还能够通过设置导向管200端部的朝向和位置，对牵引绳穿出导向管200后的位置进行限定和引导，从而避免牵引绳从管体100侧壁穿出后还可能与适配器400之间发生干涉。Further, as shown in FIG. 3 , the above-mentioned insertion tube also includes a guide tube 200 fixed on the tube body 100. At least a part of the guide tube 200 is located outside the insertion tube. One end of the guide tube 200 communicates with the guide hole 120, and the other end of the guide tube 200 is located outside the tube body 100. The traction rope passes through the guide tube 200 in the traction channel 110 and reaches outside the tube body 100. On the one hand, because the diameter of the traction rope is very small and belongs to thin wire, the traction rope will be bent when it reaches the outside of the pipe body 100 from the traction channel 110. Therefore, the curved part of the traction rope will continuously cut the hole wall of the guide hole 120 that the curved part touches during the movement process, which will easily lead to deformation of the traction hole and damage to the pipe body 100. For this, setting the guide tube 200 can isolate the traction rope from the guide hole 120, thereby avoiding deformation of the traction hole and damage to the pipe body 100. Preferably, the guide pipe 200 is made of a material with high wear resistance. Made of, for example, steel, ceramics, etc., so that the wear resistance of the guide pipe 200 is higher than that of the pipe body 100 . On the other hand, after the guide tube 200 is set, the orientation and position of the end of the guide tube 200 can also be set to limit and guide the position of the traction rope passing through the guide tube 200, so as to avoid possible interference between the traction rope and the adapter 400 after passing through the side wall of the pipe body 100.
结合图4和图5所示，导向管200包括第一管段210和第二管段220，第一管段210和第二管段220均为直管，且第一管段210和第二管段220一体成型，第一管段210和第二管段220相对弯折形成钝角的夹角。其中，第一管段210置于牵引通道110内，且第一管段210的轴线方向与牵引通道110的轴线方向平行，以实现第一管段210沿管体100的轴向方向置于所述牵引通道110内。第二管段220相对第一管段210弯折，且第二管段220从引导孔120内穿出至管体100外，牵引绳在牵引通道110内进入第一管段210中，通过第一管段210对牵引绳进行引导，使牵引绳由第一管段210进入第二管段220并穿出，从而对牵引绳的穿出位置进行导向。4 and 5, the guide pipe 200 includes a first pipe section 210 and a second pipe section 220. The first pipe section 210 and the second pipe section 220 are straight pipes, and the first pipe section 210 and the second pipe section 220 are integrally formed. The first pipe section 210 and the second pipe section 220 are relatively bent to form an obtuse angle. Wherein, the first pipe section 210 is placed in the traction passage 110 , and the axial direction of the first pipe section 210 is parallel to the axial direction of the traction passage 110 , so that the first pipe section 210 is placed in the traction passage 110 along the axial direction of the pipe body 100 . The second pipe section 220 is bent relative to the first pipe section 210, and the second pipe section 220 passes through the guide hole 120 to the outside of the pipe body 100. The traction rope enters the first pipe section 210 in the traction channel 110, and guides the traction rope through the first pipe section 210, so that the traction rope enters the second pipe section 220 from the first pipe section 210 and passes out, thereby guiding the exit position of the traction rope.
需要提出的，当管体100的结构如1所示时，则可以将导向管200的第一管段210从引导孔120插入至牵引通道110中，再通过封胶的方式将导向管200与管体100固定。当管体100的结构如图2所示时，则可以件导向管200从管体100的近端端面的开口处插入至引导孔120中，再通过封胶的方式将导向管200与管体100固定。It should be mentioned that when the structure of the tube body 100 is shown in 1, the first tube section 210 of the guide tube 200 can be inserted into the traction channel 110 from the guide hole 120, and then the guide tube 200 and the tube body 100 can be fixed by sealing. When the structure of the tube body 100 is as shown in Figure 2, the guide tube 200 can be inserted into the guide hole 120 from the opening of the proximal end surface of the tube body 100, and then the guide tube 200 and the tube body 100 can be fixed by sealing.
在如图7所示的实施例中，导向管200固定在连接套300上，连接套300为插入管的组成部分之一，连接套300呈环形，连接套300可套设固定在管体100外，导向管200位于连接套300的外侧，且导向管200的端部则贯穿连接套300的外侧壁，通过调整连接套300的位置，则可以使导向管200的端部朝向引导孔120且与引导孔120连通。连接套300与管体100的固定方式可以是通过过盈配合连接实现套接固定，也可以是通过封胶的方式实现固定，对此，本实施例不做具体限制。设置连接套300之后，则能够更加方便的控制导向管200所在的位置，同时，通过将连接套300与管体100固定能够实现对导向管200与管体100的固定，相较于直接将导向管200固定在管体100上更加容易、方便。In the embodiment shown in Figure 7, the guide tube 200 is fixed on the connecting sleeve 300, which is one of the components of the insertion tube, and the connecting sleeve 300 is annular. And communicate with the guide hole 120 . The fixing method of the connecting sleeve 300 and the pipe body 100 can be achieved by socket fixing through interference fit connection, or can be fixed by sealing glue, which is not specifically limited in this embodiment. After the connecting sleeve 300 is installed, the position of the guide tube 200 can be more conveniently controlled. At the same time, the guide tube 200 and the tube body 100 can be fixed by fixing the connecting sleeve 300 and the tube body 100, which is easier and more convenient than directly fixing the guide tube 200 on the tube body 100.
需要提出的是，当管体100的结构如图2所示时，则可以将导向管200与连接套300相连接的一端凸出于连接套300的内壁形成凸起部，使得连接套300在从管体100的近端套设于管体100上的过程中，凸起部能够从管体100的近端的开口121处进入引导孔120中，通过引导孔120进行导向，使连接套300到达预设位置，之后再将连接套300固定在管体100上。通过凸起部能够更加方便对导向管200进行定位。What needs to be mentioned is that when the structure of the tubular body 100 is as shown in FIG. 00 reaches the preset position, and then the connecting sleeve 300 is fixed on the pipe body 100 . The guide tube 200 can be positioned more conveniently through the raised portion.
在本实施例中，连接套300与导向管200为一体成型结构，其根据材质的不同，可以采用注塑、加工、3D打印等技术实现。在一些可选实施方式中，连接套300与导向管200为可拆卸连接，其可以采用螺纹连接、卡扣连接等方式实现。In this embodiment, the connecting sleeve 300 and the guide tube 200 are integrally formed, which can be realized by injection molding, processing, 3D printing and other technologies according to different materials. In some optional embodiments, the connection sleeve 300 is detachably connected to the guide tube 200 , which can be realized by means of threaded connection, buckle connection and the like.
另外，需要提出的是，根据插入管所能够实现的弯曲方向的不同，插入管上所连接的牵引绳的数量也会相应的改变，通常情况下，每一根牵引绳能够控制插入管的一个弯曲方向。相应的，管体100内的牵引通道110的数量也可以相应的改变，并且，每个牵引通道110分别对应一个引导孔120。优选的，每个牵引通道110内分别容纳一根牵引绳。在本实施例中的管体100上，牵引通道110的数量为两个，两个牵引通道110间隔设置。以使管体100形成多腔管结构，并且，部分多腔管的管体100中，除了牵引通道110外，还设置有器械通道130、流体通道140等，器械通道130通常用于容纳器械，以通过器械通道130进入病灶组织区域，以实现活检取样、手术等，流体通道140通常用于输送液体，液体可以是药液，也可以是人体的组织液。In addition, it should be pointed out that, according to the different bending directions that the insertion tube can achieve, the number of traction ropes connected to the insertion tube will also change accordingly. Usually, each traction rope can control a bending direction of the insertion tube. Correspondingly, the number of traction channels 110 in the tube body 100 can also be changed accordingly, and each traction channel 110 corresponds to a guide hole 120 . Preferably, one traction rope is accommodated in each traction channel 110 . On the tube body 100 in this embodiment, there are two traction channels 110, and the two traction channels 110 are arranged at intervals. The tube body 100 forms a multi-lumen tube structure, and part of the multi-lumen tube body 100 is provided with an instrument channel 130, a fluid channel 140, etc. in addition to the traction channel 110. The instrument channel 130 is usually used to accommodate instruments, so as to enter the lesion tissue area through the instrument channel 130 to achieve biopsy sampling, surgery, etc. The fluid channel 140 is usually used to transport liquid, which can be liquid medicine or tissue fluid of the human body.
基于上述的插入管，本实施例中还提供了一种对接组件，该对接组件的结构如图6和图9所示，包括适配器400和上述的插入管，适配器400为固定在内窥镜手柄上、用于连接插入管的部件，适配器400结构如图10所示，适配器400上具有对接通道410，该对接通道410的一端贯穿适配器400的表面形成对接口，管体100的近端则从对接通道410的对接口插接固定在对接通道410中。Based on the above-mentioned insertion tube, this embodiment also provides a docking assembly. The structure of the docking assembly is shown in Figures 6 and 9, including an adapter 400 and the above-mentioned insertion tube. The docking interface is plugged and fixed in the docking channel 410 .
进一步的，上述的对接通道410内设置有挡板420，挡板420与对接通道410的对接口之间的距离小于或等于引导孔120与管体100的近端的端面之间的距离，以使得管体100的近端插入对接通道410以后能够与挡板420相抵接，同时，对接通道410的侧壁也不会遮挡引导孔120。挡板420则起到了对管体100的定位和限位作用。另外，当管体100内还具有流体通道140时，由于流体通道140内的液体需要达到防止被污染的效果，因此，在本实施中，挡板420则能够对流体通道140的端面进行封闭，以防止流体通道140内的流体在适配器400内串流至牵引通道110内和/或器械通道130内而被污染。Further, the above-mentioned docking channel 410 is provided with a baffle 420 , the distance between the baffle 420 and the docking port of the docking channel 410 is less than or equal to the distance between the guide hole 120 and the end face of the proximal end of the tube body 100 , so that the proximal end of the tube body 100 can abut against the baffle 420 after being inserted into the docking channel 410 , and at the same time, the side wall of the docking channel 410 will not block the guide hole 120 . The baffle 420 plays a role of positioning and limiting the tube body 100 . In addition, when the tube body 100 also has a fluid channel 140, since the liquid in the fluid channel 140 needs to achieve the effect of preventing contamination, therefore, in this implementation, the baffle plate 420 can seal the end face of the fluid channel 140 to prevent the fluid in the fluid channel 140 from flowing through the adapter 400 into the traction channel 110 and/or the instrument channel 130 to be polluted.
进一步的，在管体100的近端外壁与对接通道410的内壁中，其中一者上设置有凸起的定位部430，另一者上设置有与定位部相适配的定位槽，在管体100与对接通道410插接过程中，定位部430插接于定位槽中并沿定位槽滑动，从而通过定位槽与定位部430的配合，使得管体100插入对接通道410内以后，挡板420能够准确的封堵流体通道140的端部。Further, among the proximal outer wall of the tube body 100 and the inner wall of the docking channel 410, one of them is provided with a raised positioning part 430, and the other is provided with a positioning slot matching the positioning part. During the insertion process of the tube body 100 and the docking channel 410, the positioning part 430 is inserted into the positioning slot and slides along the positioning slot, so that through the cooperation of the positioning slot and the positioning part 430, the tube body 100 is inserted into the docking channel 410. The plate 420 can accurately block the end of the fluid channel 140 .
在本实施例中，定位部430设置在适配器400的对接通道410内，定位槽则直接采用管体上的引导孔，从而无需单独设置另外的定位槽。In this embodiment, the positioning part 430 is arranged in the docking channel 410 of the adapter 400, and the positioning groove directly adopts the guide hole on the pipe body, so that there is no need to separately arrange another positioning groove.
