The reusable section comprises: a housing, the distant end of the housing being provided with a butt joint part, and the butt joint part being used for being connected with a disposable section (20) of the endoscope handle; a driving part, the driving part comprising an operating unit (11) and a driving unit, the operating unit (11) being arranged on the outer side of the housing, the driving unit being mounted in an accommodating space defined by the housing, and the driving unit being in transmission fit connection with the operating unit (11); and a transmission part, the transmission part at least comprising a first transmission rod (101) and a second transmission rod (102), the proximal ends of the first transmission rod (101) and the second transmission rod (102) being cooperatively connected to the driving unit. When an operator shifts a shifting lever and a thumbwheel, the amplitude of the movement of the first transmission rod (101) and the second transmission rod (102) in a preset direction is greater than a unit rotation angle of a first driven gear (13). Therefore, it is beneficial to obtain a larger bending angle by shifting at a smaller range.

Description

一种内窥镜手柄可重复使用段、内窥镜手柄及内窥镜A reusable segment of an endoscope handle, an endoscope handle and an endoscope 技术领域Technical field
本发明属于内窥镜技术领域，涉及一种内窥镜手柄可重复使用段，一种内窥镜手柄，尤其是涉及一种内窥镜。The invention belongs to the technical field of endoscopes, and relates to a reusable section of an endoscope handle, an endoscope handle, and in particular to an endoscope.
背景技术Background technique
内窥镜是一种通过将具有至少照明、拍摄功能的***部伸入至人体的自然通道或者术区开孔中，进行人体的体腔环境探测，通过操作位于人体外部的手柄，对位于内窥镜***部前端的主动弯曲部分进行弯曲角度调节，从而使其在预定的方向进行偏转，帮助人们获取更大可视角度范围的观察。An endoscope is a device that detects the body cavity environment by inserting an insertion part with at least lighting and photographing functions into the natural passage of the human body or the opening of the surgical area, and operates a handle located outside the human body to view the endoscope. The active bending part at the front end of the mirror insertion part adjusts the bending angle so that it can deflect in a predetermined direction, helping people obtain observations within a wider viewing angle range.
另外，通常内窥镜的***部上还设置有器械通道，在人体的体腔环境的探测或治疗过程中，需要对人体的内部组织的多余积液进行抽吸，积液经器械通道导出至体外，另外，器械通道还用于外部器械，如活检钳顺着器械通道伸入至体腔中，达到目标靶向组织后，钳取部分人体组织进行活检检测。In addition, the insertion part of the endoscope is usually provided with an instrument channel. During the detection or treatment of the body cavity environment, excess fluid accumulation in the internal tissues of the human body needs to be aspirated, and the accumulated fluid is exported to the outside of the body through the instrument channel. , In addition, the instrument channel is also used for external instruments, such as biopsy forceps extending into the body cavity along the instrument channel. After reaching the target tissue, part of the human tissue is taken for biopsy detection.
因此，当***部***至人体后，其外部以及内部的器械通道被严重污染，通常的做法是将***部连带手柄整体进行抛弃，因此成本较高，患者难以支撑高昂的器材费用；另外，现有的内窥镜的主动弯曲部分通过设置在手柄上的拨杆或者转动轮，对主动弯曲部分的弯曲程度进行调节，然而现有技术中主动弯曲部分的弯曲过程转角精度难以把控。Therefore, when the insertion part is inserted into the human body, the external and internal instrument channels are seriously contaminated. The common practice is to discard the insertion part and the handle as a whole. Therefore, the cost is high, and it is difficult for patients to support the high cost of equipment; in addition, now The bending degree of the active bending part of some endoscopes is adjusted through a lever or a rotating wheel provided on the handle. However, in the prior art, the accuracy of the bending angle of the active bending part during the bending process is difficult to control.

有益效果：Beneficial effects:
1、本发明中，当操作者拨动拨杆或者拨轮时，第一传动杆和第二传动杆往预设方向移动的幅度将大于第一从动齿轮的单位旋转角度，因此，操作者在将主动弯曲部弯曲至极限位置过程中所需要拨动拨杆或者拨轮的范围将缩小，从而有益于通过拨动较小的范围而获得更大的弯曲角度；1. In the present invention, when the operator moves the lever or wheel, the first transmission rod and the second transmission rod move in the preset direction by an amplitude greater than the unit rotation angle of the first driven gear. Therefore, the operator In the process of bending the active bending part to the extreme position, the range of the lever or wheel that needs to be moved will be reduced, which is beneficial to obtain a larger bending angle by moving the smaller range;
2、本发明中，现有技术中，为达到上述效果需要采用多级齿轮组的啮合，然而本发明中，仅需一个齿轮即解决了上述问题，而且结构简单，舍弃了多级齿轮的方案可以降低内窥镜手柄的制造成本，对患者而言更加有益；另外，通常手柄内的布局空间及其有限，较多的部件将增加手柄内部空间的结构布局难度，另外，手柄的外形结构需要符合人体工程学，从而方便操作者使用。2. In the present invention, in the prior art, the meshing of multi-stage gear sets is required to achieve the above effect. However, in the present invention, only one gear is needed to solve the above problem, and the structure is simple, and the multi-stage gear scheme is abandoned. It can reduce the manufacturing cost of the endoscope handle, which is more beneficial to patients; in addition, usually the layout space inside the handle is extremely limited, and more components will increase the structural layout difficulty of the internal space of the handle. In addition, the shape and structure of the handle require Ergonomically designed for operator convenience.

Another one of the rods 101 is provided with a first slide block 1012 that is cooperatively connected with the first slide groove 132;
以及，所述第一从动齿轮13和所述第二传动杆102中的任意一者设置有第二滑槽131，所述第一从动齿轮13和所述第二传动杆102中的另一者设置有与所述第二滑槽131配合连接的第二滑块1022。And, any one of the first driven gear 13 and the second transmission rod 102 is provided with a second chute 131, and the other of the first driven gear 13 and the second transmission rod 102 is provided with a second slide groove 131. One is provided with a second slide block 1022 mated and connected with the second slide groove 131 .
为保障第一传动杆101和第二传动杆102在预定的方向移动，因此在所述壳体内的安装板16上固定设置有包围所述第一传动杆101和第二传动杆102的第一导向孔163和第二导向孔160。In order to ensure that the first transmission rod 101 and the second transmission rod 102 move in a predetermined direction, a first transmission rod surrounding the first transmission rod 101 and the second transmission rod 102 is fixedly provided on the mounting plate 16 in the housing. Guide hole 163 and second guide hole 160 .
在图4中示出的实施方案中，所述第一滑槽132和第二滑槽131均安装于所述第一从动齿轮13上；且所述第一滑槽132和第二滑槽131对称设置于所述第一从动齿轮13的旋转中心两侧。在该实施例中，第一传动杆101和第二传动杆102上分别设置配合第一滑槽132和第二滑槽131的第一滑块1012和第二滑块1022；当第一从动齿轮13受迫转动时，请结合附图5所示，第一从动齿轮13绕其旋转中心的安装螺栓15逆时针旋转使第一传动杆101和第二传动杆102达到图5所示中的位置，需要进行说明的是，第一滑槽132和第二滑槽131在转动过程中同时在相反的方向推动第一滑块1012和第二滑块1022移动，从而使第一传动杆101和第二传动杆102在预设的行动轨迹上做直线运动，在第一传动杆101和第二传动杆102作用下使位于内窥镜手柄可抛弃段20中的第一推杆201和第二推杆202沿第一传动杆101和第二传动杆102的移动方向同步移动，以使分别连接在第一推杆201和第二推杆202上的第一牵引绳2011和第二牵引绳2021移动，进而调节设置在可抛弃段20上的主动弯曲部弯曲；其中，可抛弃段20上的主动弯曲部弯曲角度通过调节拨轮的转动角度来实现。In the embodiment shown in Figure 4, the first chute 132 and the second chute 131 are both installed on the first driven gear 13; and the first chute 132 and the second chute 131 are installed on the first driven gear 13; 131 are symmetrically arranged on both sides of the rotation center of the first driven gear 13 . In this embodiment, the first transmission rod 101 and the second transmission rod 102 are respectively provided with a first slide block 1012 and a second slide block 1022 that cooperate with the first slide groove 132 and the second slide groove 131; when the first driven When the gear 13 is forced to rotate, as shown in Figure 5, the first driven gear 13 rotates counterclockwise around the mounting bolt 15 at its rotation center to make the first transmission rod 101 and the second transmission rod 102 reach the position shown in Figure 5. The position of and the second transmission rod 102 make linear motion on the preset movement trajectory. Under the action of the first transmission rod 101 and the second transmission rod 102, the first push rod 201 and the second push rod 201 located in the disposable section 20 of the endoscope handle are moved. The two push rods 202 move synchronously along the moving directions of the first transmission rod 101 and the second transmission rod 102, so that the first traction rope 2011 and the second traction rope respectively connected to the first push rod 201 and the second push rod 202 2021 moves to adjust the bending of the active bending portion provided on the disposable section 20; wherein, the bending angle of the active bending section on the disposable section 20 is achieved by adjusting the rotation angle of the dial.
需要进行说明的是，现有技术中主动弯曲部的弯曲角度是通过调节拨杆或者拨轮实现，当拨杆或者拨轮旋转预设的角度，则主动弯曲部的弯曲角度对应弯曲相应的角度；因此，当弯曲部的弯曲角度需要调节至达到极限弯曲角度的过程中，拨杆或者拨轮对应的旋转角度也较大，需要进行说明的是，内窥镜手柄的使用过程中通常是需要单手操作。然而，单手操作过程中，对弯曲部大角度范围的调节具有一定难度。原因在于，当手在握住内窥镜手柄保持稳定性的同时，需要手指活动较大范围的幅度来拨动拨杆或者拨轮，这对于不同操作个体而言难度是不同的，另外，操作者在操作拨轮或者拨杆的过程中难以通过手感来判断主动弯曲部的弯曲情况。It should be noted that in the prior art, the bending angle of the active bending part is achieved by adjusting the lever or dial. When the lever or dial rotates a preset angle, the bending angle of the active bending part corresponds to the corresponding bending angle. ; Therefore, when the bending angle of the bending part needs to be adjusted to reach the extreme bending angle, the corresponding rotation angle of the lever or dial is also larger. It should be noted that it is usually necessary to use the endoscope handle. One-handed operation. However, it is difficult to adjust the large angle range of the bending part during one-handed operation. The reason is that while the hand maintains stability while holding the handle of the endoscope, the fingers need to move within a wide range to move the lever or dial, which is difficult for different operating individuals. In addition, the operation It is difficult for the user to judge the bending condition of the active bending part through the feel when operating the dial or lever.
为解决上述问题，本发明中提供的将所述第一滑槽132和第二滑槽131均安装于所述第一从动齿轮13上；且所述第一滑槽132和第二滑槽131对称设置于所述第一从动齿轮13的旋转中心两侧。请结合图6所示，当逆时针驱动第一从动齿轮13，从a位置旋转到b位置，该过程中由于第一传动杆101和第二传动杆102只能沿箭头指示的预定方向移动，因此第一滑块1012和第二滑块1022到达第一从动齿轮13的旋转中心的高度为H，并且该高度H不会随着第一传动杆101、第二传动杆102以及第一从动齿轮13的运动而发生变化，因此第一滑块1012从a位置移动到b位置的横向位移为L，该横向位移L与第一从动齿轮13的旋转角度θ相关，于是可以总结出H、L和θ之间的关系为下式：L＝H·tanθ；可以得到第一滑块从a位置移动到b位置的过程仅与第一从动齿轮13的旋转角度θ相关；进而，可以推导出L随θ变化的速率如下式:：L′＝H/cos2θ，由于第一滑块1012从a位置移动到b位置的过程，θ从0开始增加，L′＝H/cos2θ逐渐增大；因此，可以得到当操作者拨动拨杆或者拨轮时，第一传动杆101和第二传动杆102往预设方向移动的幅度将大于第一从动齿轮13的单位旋转角度，因此，操作者在将主动弯曲部弯曲至极限位置过程中所需要拨动拨杆或者拨轮的范围将缩小，从而有益于通过拨动较小的范围而获得更大的弯曲角度；现有技术中，为达到上述效果需要采用多级齿轮组的啮合，然而本发明中，仅需一个齿轮即解决了上述问题，而且结构简单，舍弃了多级齿轮的方案可以降低内窥镜手柄的制造成本，对患者而言更加有益；另外，通常手柄内的布局空间及其有限，较多的部件将增加手柄内部空间的结构布局难度，另外，手柄的外形结构需要符合人体工程学，从而方便操作者使用。In order to solve the above problem, the present invention provides that the first chute 132 and the second chute 131 are both installed on the first driven gear 13; and the first chute 132 and the second chute 131 are installed on the first driven gear 13; 131 are symmetrically arranged on both sides of the rotation center of the first driven gear 13 . As shown in Figure 6, when the first driven gear 13 is driven counterclockwise and rotates from position a to position b, during this process, the first transmission rod 101 and the second transmission rod 102 can only move in the predetermined direction indicated by the arrow. , therefore the height at which the first slider 1012 and the second slider 1022 reach the rotation center of the first driven gear 13 is H, and this height H does not change with the first transmission rod 101 , the second transmission rod 102 and the first The movement of the driven gear 13 changes, so the lateral displacement of the first slider 1012 from position a to position b is L. This lateral displacement L is related to the rotation angle θ of the first driven gear 13, so it can be concluded that The relationship between H, L and θ is the following formula: L=H·tanθ; it can be obtained that the process of the first slider moving from position a to position b is only related to the rotation angle θ of the first driven gear 13; further, The rate of change of L with θ can be deduced as follows: L′=H/cos 2 θ. Due to the process of the first slider 1012 moving from position a to position b, θ starts to increase from 0, L′=H/cos 2 θ gradually increases; therefore, it can be obtained that when the operator moves the lever or dial, the amplitude of the first transmission rod 101 and the second transmission rod 102 moving in the preset direction will be greater than the unit of the first driven gear 13 Rotation angle, therefore, the range in which the operator needs to turn the lever or dial when bending the active bending part to the extreme position will be reduced, which is beneficial to obtain a larger bending angle by turning a smaller range; In the prior art, in order to achieve the above effect, it is necessary to adopt the meshing of multi-stage gear sets. However, in the present invention, only one gear is needed to solve the above problem, and the structure is simple. The solution of abandoning the multi-stage gear can reduce the size of the endoscope handle. The manufacturing cost is lower, which is more beneficial to patients; in addition, the layout space inside the handle is usually extremely limited, and more components will increase the structural layout difficulty of the inner space of the handle. In addition, the shape and structure of the handle need to comply with ergonomics, so that Convenient for operators to use.
与此同时，请结合图7所示，在转动第一从动齿轮13的过程中，当第一滑块1012位于a位置时，第一滑槽132的槽壁施加给第一滑块1012的力为f，达到b位置后，若操作者施加的力不变依然为f，则第一滑槽132沿预设方向推动第一滑块1012的力为f1，结合图7中所示力的分解原理，f1＝f·cosθ＜f；因此，意味着操作者将第一滑块1012从a位置移动到b位置的过程中，在保障相同转动速度下，需要更大的驱动力；换言之，将第一滑块1012从a位置移动到b位置的过程中，操作者可以在拨动拨轮或拨杆时获得更好的驱动手感；从而更有益于操作者通过力的反馈来判断主动弯曲部的弯曲情况，帮助操作者在操作过程中获得更好的手感，快速帮助操作者适应内窥镜手柄的使用。At the same time, as shown in FIG. 7 , during the rotation of the first driven gear 13 , when the first slider 1012 is located at position a, the groove wall of the first slider 132 exerts force on the first slider 1012 The force is f. After reaching position b, if the force exerted by the operator remains f, the force of the first chute 132 pushing the first slider 1012 in the preset direction is f1. Combined with the force shown in Figure 7 According to the decomposition principle, f1=f·cosθ<f; therefore, it means that when the operator moves the first slider 1012 from position a to position b, greater driving force is required to ensure the same rotation speed; in other words, In the process of moving the first slider 1012 from position a to position b, the operator can obtain a better driving feel when turning the dial or lever; thus it is more beneficial for the operator to judge active bending through force feedback. The curvature of the end helps the operator get a better feel during operation and quickly helps the operator adapt to the use of the endoscope handle.
在本发明其它实施例中，所述第一滑槽132和第二滑槽131以所述第一从动齿轮13的旋转中心为对称中心呈中心对称。从而使第一传动杆101和第二传动杆102获得同步位移。In other embodiments of the present invention, the first chute 132 and the second chute 131 are centrally symmetrical with the rotation center of the first driven gear 13 as the symmetry center. As a result, the first transmission rod 101 and the second transmission rod 102 obtain synchronous displacement.
请结合图4至图7，所述第一滑槽132和第二滑槽131沿所述第一从动齿轮13径向的末端具有开放型缺口。该开放型缺口可以有益于第一滑块1012和第二滑块1022的安装，从而提高了手柄的组装效率。Please refer to FIGS. 4 to 7 , the first chute 132 and the second chute 131 have open notches at their radial ends along the first driven gear 13 . The open notch can facilitate the installation of the first slide block 1012 and the second slide block 1022, thereby improving the assembly efficiency of the handle.
在本发明另外的实施例中，所述第一滑槽132和第二滑槽131沿所述第一从动齿轮13径向的末端还可以为封闭结构，可以防止第一滑块1012和第二滑块1022沿第一从动齿轮13的径向滑离第一滑槽132和第二滑槽131。In another embodiment of the present invention, the ends of the first slide groove 132 and the second slide groove 131 along the radial direction of the first driven gear 13 can also be a closed structure, which can prevent the first slide block 1012 and the The two slide blocks 1022 slide away from the first slide groove 132 and the second slide groove 131 along the radial direction of the first driven gear 13 .
