本申请涉及医疗器械技术领域，尤其涉及一种手术器械冲洗装置以及手术器械结构。The present application relates to the technical field of medical instruments, and in particular to a surgical instrument flushing device and a surgical instrument structure.
手术机器人使用手术器械通常比较昂贵，如果可以被重复使用，将大大降低使用成本。然而，医疗器械会直接接触患者，因此必须消毒才能重复使用。在进行消毒之前，通常必须清洁器械以去除在之前的程序中可能已经进入器械的任何流体、微粒或其他污染物。但是将结构复杂的手术器械完全拆卸是不切实际的，因此在清洁过程中会涉及到使用清洗液直接冲刷手术器械内部的程序。但是手术器械中轴管部分形状构造等原因导致比较难冲洗。Surgical instruments used in surgical robots are usually expensive, and if they can be reused, the cost of use will be greatly reduced. However, medical instruments will come into direct contact with the patient, so they must be sterilized before they can be reused. Before sterilization, the instrument must usually be cleaned to remove any fluids, particles or other contaminants that may have entered the instrument during previous procedures. However, it is impractical to completely disassemble complex surgical instruments, so the cleaning process involves using cleaning fluid to directly flush the inside of the surgical instrument. However, the shape and structure of the shaft tube part of the surgical instrument make it difficult to flush.
在一些情形下，用于手术器械内部冲洗装置的结构简单，功能单一，仅能对自身设置有注水管或密封结构的手术器械能够进行清洗，应用范围较小。In some cases, the internal flushing device for surgical instruments has a simple structure and a single function, and can only clean surgical instruments that are provided with a water injection pipe or a sealing structure, and has a small application range.

In the embodiment of the present application, the surgical instrument 50 may be a handheld surgical instrument or a surgical instrument for a surgical robot. The surgical instrument 50 may include an instrument shaft tube 51, a working end 52 and an instrument rear end 53, the instrument shaft tube 51 connects the working end 52 and the instrument rear end 53, and the instrument rear end 53 can drive the working end 52 to perform surgical operations. In the embodiment of the present application, when the surgical instrument 50 needs to be cleaned, the flushing device 10 is used to cover the structure of the working end 52 and part of the shaft tube 51 of the surgical instrument to create a closed environment for the working end 52 and the shaft tube 51.
参照图2和图3和图5，手术器械的冲洗装置10可以包括筒组件，筒组件可以是多个可分离的结构组装形成，筒组件内部具有空腔20，筒组件开设有第一口部101和第二口部102，第一口部101和第二口部102使得空腔与外部连通。其中，在筒组件中，除了第一口部101和第二口部102，筒组件的其他结构均不具有使得空腔20与外部形成连通的特征。可以设置第一口部101为手术器械的插入口，手术器械的执行端通过第一口部101插入空腔20时，空腔20只能通过第二口部102与外部连通。2, 3 and 5, the flushing device 10 of the surgical instrument may include a barrel assembly, which may be formed by assembling a plurality of separable structures, wherein the barrel assembly has a cavity 20 inside, and the barrel assembly is provided with a first mouth 101 and a second mouth 102, wherein the first mouth 101 and the second mouth 102 allow the cavity to communicate with the outside. In the barrel assembly, except for the first mouth 101 and the second mouth 102, the other structures of the barrel assembly do not have the feature of allowing the cavity 20 to communicate with the outside. The first mouth 101 may be set as the insertion port of the surgical instrument, and when the execution end of the surgical instrument is inserted into the cavity 20 through the first mouth 101, the cavity 20 can only communicate with the outside through the second mouth 102.

或者，在一些实施例中，第一夹紧件13也可以是分体式的结构。也即，第一夹紧部131和第一锁紧部132分别属于两个不同的部件。Alternatively, in some embodiments, the first clamping member 13 may also be a split structure, that is, the first clamping portion 131 and the first locking portion 132 are two different components.
或者，在一些实施例中，第一锁紧部132的部分也可以直接与基座12形成一件式结构。Alternatively, in some embodiments, a portion of the first locking portion 132 may also directly form a one-piece structure with the base 12 .

The second clamping member 14 may include a second clamping portion 141 and a second locking portion 142. In implementation, the second clamping member 14 is sleeved on the periphery of the partial structure of the first clamping member 13, for example, the second clamping portion 141 is located at the periphery of the first clamping portion 131, and the second locking portion 142 is located at the periphery of the first locking portion 132. In an embodiment, the second clamping member 14 forms a movable relationship with the first clamping member 13, and the second clamping member 14 can produce partial structural dislocation movement along the first direction X relative to the first clamping member 13, so that the second clamping member 14 or the first clamping portion 141 can be located at the first position A or the second position B. The movement mode of the second clamping member 14 can be a spiral rotation relative to the first clamping member 13, or a linear movement. When the second clamping member 14 moves relative to the first clamping member 13 or is in a different position, the second clamping portion 141 has a different effect on the first clamping portion 131. Or different forces drive the structural state of the first clamping part 131 to change to a certain extent. The specific connection structure between the second clamping member 14 and the first clamping member 13 will be described in detail below.

This embodiment is described using a seal 11 having a cylindrical outer shape. The seal 11 may include a sealing portion 111 and an extension portion 112. The sealing portion 111 is located at one end of the seal 112. The extension portion 112 is fixedly connected or passively fixedly connected to the second end of the base 12. In implementation, the possibility of a gap between the extension portion 112 of the seal 11 and the base 12 is not considered, and the possibility of relative movement between the extension portion 112 of the seal 11 and the base 12 is basically not considered.
在一些实施例中，密封件2选用具备形变能力的材料，例如橡胶、硅胶等材质。In some embodiments, the sealing member 2 is made of a material with deformation capability, such as rubber, silicone and the like.
在本实施例中，基座12开设的腔20a、密封件11开设的通孔20d均为空腔20的一部分。第一夹紧件开设的腔20b，第二夹紧件开设的腔20c均由于安装有构件，导致未与腔20a和通孔20d未形成连通的关系。在其他的实施例中，取决于第一夹紧部131/第一夹紧件13、第二夹紧部141/第二夹紧件14与基座12、密封部111/密封件11的结构设置方或连接关系，腔20c和腔20b也可能构成空腔20的一部分。在本申请的实施例中，空腔20是用于容纳手术器械50的工作端头52和轴管51的空间，且空腔20的内壁与工作端头52或轴管51之间具有足够的空间流经清洗液即满足本申请实施例的条件，并不对空腔20的具体结构做其他限定。In this embodiment, the cavity 20a opened by the base 12 and the through hole 20d opened by the sealing member 11 are both part of the cavity 20. The cavity 20b opened by the first clamping member and the cavity 20c opened by the second clamping member are not connected with the cavity 20a and the through hole 20d due to the installation of components. In other embodiments, depending on the structural setting or connection relationship between the first clamping part 131/first clamping member 13, the second clamping part 141/second clamping member 14 and the base 12, the sealing part 111/sealing member 11, the cavity 20c and the cavity 20b may also constitute a part of the cavity 20. In the embodiment of the present application, the cavity 20 is a space for accommodating the working end 52 and the shaft tube 51 of the surgical instrument 50, and there is enough space between the inner wall of the cavity 20 and the working end 52 or the shaft tube 51 to flow through the cleaning liquid, which meets the conditions of the embodiment of the present application, and no other restrictions are made on the specific structure of the cavity 20.
以下对第一夹紧件13、第二夹紧件14和密封件11的夹紧密封的功能进行详细阐述。参照图5、图7和图8，在本申请的实施方式中，第一夹紧部131套设于密封部111的外周，至少部分第二夹紧部141设置于第一夹紧部131的外周，所第二夹紧部141相对于第一夹紧部131具有沿第一方向X的第一位置A和第二位置B之间的活动的余量。并且，当第二夹紧部141处于第一位置A时，第二夹紧部141与第一夹紧部131接触配合，第一夹紧部131与密封部111接触配合，当第二夹紧部141处于第二位置B时，第二夹紧部141与第一夹紧部131压紧配合，第二夹紧部141对第一夹紧部131具有压力f，压力f包括有与第一方向X垂直的分力，使得第一夹紧部131产生形变，进而使得第一夹紧部131对密封部111产生垂直于第一方向X的分力，第一夹紧部131与密封部111压紧配合。The clamping and sealing functions of the first clamping member 13, the second clamping member 14 and the sealing member 11 are described in detail below. Referring to Figures 5, 7 and 8, in the embodiment of the present application, the first clamping portion 131 is sleeved on the outer periphery of the sealing portion 111, and at least part of the second clamping portion 141 is disposed on the outer periphery of the first clamping portion 131, so that the second clamping portion 141 has a margin of movement between a first position A and a second position B along the first direction X relative to the first clamping portion 131. Furthermore, when the second clamping portion 141 is in the first position A, the second clamping portion 141 is in contact with and cooperates with the first clamping portion 131, and the first clamping portion 131 is in contact with and cooperates with the sealing portion 111; when the second clamping portion 141 is in the second position B, the second clamping portion 141 is pressed and fitted with the first clamping portion 131, and the second clamping portion 141 has a pressure f on the first clamping portion 131, and the pressure f includes a component force perpendicular to the first direction X, so that the first clamping portion 131 is deformed, and the first clamping portion 131 generates a component force perpendicular to the first direction X on the sealing portion 111, and the first clamping portion 131 is pressed and fitted with the sealing portion 111.
在本申请的实施方式中，由于手术器械50的工作端头52需要从密封部111的第一口部101插入，由于工作端头52是不规则的结构，为了方便器工作端头52的顺利插入，因此密封部111可能会留有能够让工作端头52顺利插入的空隙余量。如位于密封部111的第一口部101适配了工作端头52的大小或松紧程度，相应的，第一口部101与手术器械50的轴管51的适配度可能不够高，从而导致密封部111的密封效果得不到明显的提升。在本实施例中，当第二夹紧件14或第二夹紧部141处于第一位置A时，第二夹紧部141对第一夹紧部131在垂直于第一方向X的方向压力较小或没有压力，相应的，第一夹紧部131对密封部111在垂直于第一方向X的压力也较小或没有压力，此时密封部111处于其自身的自然状态，可以方便手术器械50的工作端头52和轴管51插入。当工作端头52和轴管51插入到位后，第二夹紧部141移动至第二位置B，第二夹紧部141对第一夹紧部131具有在垂直于第一方向X的压力，使得第一夹紧部131产生微弱的形变，进而对密封部111具有在垂直于第一方向X的压力，使得密封部111产生形变，挤压或挤占密封部111与轴管51之间的空隙余量，从而达到密封部111的密封效果。In the embodiment of the present application, since the working end 52 of the surgical instrument 50 needs to be inserted from the first opening 101 of the sealing part 111, and since the working end 52 is an irregular structure, in order to facilitate the smooth insertion of the working end 52, the sealing part 111 may leave a gap margin that allows the working end 52 to be smoothly inserted. If the first opening 101 of the sealing part 111 is adapted to the size or tightness of the working end 52, the adaptability of the first opening 101 to the shaft tube 51 of the surgical instrument 50 may not be high enough, resulting in the sealing effect of the sealing part 111 not being significantly improved. In this embodiment, when the second clamping member 14 or the second clamping portion 141 is in the first position A, the second clamping portion 141 exerts little or no pressure on the first clamping portion 131 in a direction perpendicular to the first direction X. Correspondingly, the first clamping portion 131 also exerts little or no pressure on the sealing portion 111 in a direction perpendicular to the first direction X. At this time, the sealing portion 111 is in its own natural state, which can facilitate the insertion of the working end 52 and the shaft tube 51 of the surgical instrument 50. After the working end 52 and the shaft tube 51 are inserted into place, the second clamping portion 141 moves to the second position B, and the second clamping portion 141 exerts pressure on the first clamping portion 131 in a direction perpendicular to the first direction X, causing the first clamping portion 131 to produce a slight deformation, and then exerts pressure on the sealing portion 111 in a direction perpendicular to the first direction X, causing the sealing portion 111 to produce deformation, The gap margin between the sealing portion 111 and the shaft tube 51 is squeezed or occupied, thereby achieving the sealing effect of the sealing portion 111.
在一实施例中，回到图4和图5，在一些实施例中，第一夹紧件13可以包括多个夹板131a，多个夹板131a环绕的分布于密封部的外周。多个夹板的至少部分区域形成第一夹紧部131。实施例中，“多个”表示至少2个。夹板131a的具体数量可以不做限定。图4中示意性的展示了4个夹板。多个夹板131a可单独受力，单独形变，可以分散第二夹紧部141对第一夹紧部131的应力，以达到第一夹紧部131的形变效果。进一步，任意相邻的两个夹板131a之间具有间隙131b。使得多个夹板131a的形变程度更大且均向内聚拢。In one embodiment, returning to Figures 4 and 5, in some embodiments, the first clamping member 13 may include a plurality of clamping plates 131a, and the plurality of clamping plates 131a are distributed around the periphery of the sealing portion. At least a portion of the region of the plurality of clamping plates forms the first clamping portion 131. In the embodiment, "multiple" means at least 2. The specific number of clamping plates 131a may not be limited. Four clamping plates are schematically shown in Figure 4. The plurality of clamping plates 131a can be subjected to force and deformed individually, and the stress of the second clamping portion 141 on the first clamping portion 131 can be dispersed to achieve the deformation effect of the first clamping portion 131. Furthermore, there is a gap 131b between any two adjacent clamping plates 131a. This makes the deformation degree of the plurality of clamping plates 131a greater and all gather inward.
第二夹紧部141，位于第二夹紧件14的内壁面。沿第一方向X，自第二口部102至第一口部101的方向，位于第二夹紧件14的部分内壁的内径呈渐缩趋势，该部分的内壁面则形成第二夹紧部141。也可以说，第二夹紧部141是一部分锥形内壁面。当第二夹紧部141处于第一位置A时，第二夹紧部141的锥形面与第一夹紧部131的夹板131a接触配合，位于第二夹紧部141且与第一夹紧部131配合的区域直径较大，而第二夹紧部141自第一位置A向第二位置B移动时，第二夹紧部141与第一夹紧部131配合的部分逐渐收窄，第二夹紧部141对第一夹紧部131产生包括径向方向的作用力，径向方向垂直于第一方向X，进而对逐渐收缩第一夹紧部131的口径，从而对密封部111产生压力并收缩密封部111的口径。The second clamping portion 141 is located on the inner wall surface of the second clamping member 14. Along the first direction X, from the second opening 102 to the first opening 101, the inner diameter of the inner wall of the second clamping member 14 is gradually reduced, and the inner wall surface of this part forms the second clamping portion 141. It can also be said that the second clamping portion 141 is a part of the tapered inner wall surface. When the second clamping portion 141 is in the first position A, the conical surface of the second clamping portion 141 contacts and cooperates with the clamping plate 131a of the first clamping portion 131, and the diameter of the area located in the second clamping portion 141 and cooperating with the first clamping portion 131 is larger. When the second clamping portion 141 moves from the first position A to the second position B, the part of the second clamping portion 141 that cooperates with the first clamping portion 131 gradually narrows, and the second clamping portion 141 generates a force on the first clamping portion 131 including a radial direction, and the radial direction is perpendicular to the first direction X, thereby gradually shrinking the diameter of the first clamping portion 131, thereby generating pressure on the sealing portion 111 and shrinking the diameter of the sealing portion 111.
在一些实施例中，第一夹紧部131，相应的也可以设置有锥形面。如图5，沿第一方向X，自第二口部102至第一口部101的方向，位于多个夹板131a的部分区域的外径呈渐缩趋势，该部分的壁面形成锥形面。第二夹紧部141的锥形面和第一夹紧部131的锥形面配合，使得第一夹紧部131和第二夹紧部141形成面与面的配合，更好的分散第一夹紧部131的应力，使得冲洗装置的密封效果更好。In some embodiments, the first clamping portion 131 may also be provided with a tapered surface accordingly. As shown in FIG5 , along the first direction X, from the second mouth portion 102 to the first mouth portion 101, the outer diameter of a portion of the plurality of clamping plates 131a is gradually reduced, and the wall surface of the portion forms a tapered surface. The tapered surface of the second clamping portion 141 cooperates with the tapered surface of the first clamping portion 131, so that the first clamping portion 131 and the second clamping portion 141 form a surface-to-surface cooperation, which better disperses the stress of the first clamping portion 131 and makes the sealing effect of the flushing device better.
以下对第一夹紧件13、第二夹紧件14和密封件11的锁紧功能进行详细阐述。参照图4、图5和图6，本申请的实施例中，第二夹紧件14位于第二位置B时，第二夹紧部141对第一夹紧部131压紧，进而对密封部111压紧形成密封。为了将第二夹紧部141保持在第二位置B的状态，第一夹紧部131和第二夹紧部141可以配合锁紧。在实施例中，第一锁紧部132位于第一夹紧部131背离第一口部101的一侧，也即第一夹紧部131和第一锁紧部132沿第一方向X、自第一口部101至第二口部102的方向设置。第二锁紧部142位于第二夹紧部141背离第一口部101的一侧，也即第二夹紧部141和第二锁紧部142沿第一方向X、自第一口部101至第二口部102的方向设置。第二锁紧部142和第一锁紧部132配合锁紧。The locking functions of the first clamping member 13, the second clamping member 14 and the sealing member 11 are described in detail below. Referring to Figures 4, 5 and 6, in an embodiment of the present application, when the second clamping member 14 is located at the second position B, the second clamping portion 141 presses the first clamping portion 131, and then presses the sealing portion 111 to form a seal. In order to keep the second clamping portion 141 in the state of the second position B, the first clamping portion 131 and the second clamping portion 141 can cooperate to lock. In an embodiment, the first locking portion 132 is located on the side of the first clamping portion 131 away from the first mouth portion 101, that is, the first clamping portion 131 and the first locking portion 132 are arranged along the first direction X, from the first mouth portion 101 to the second mouth portion 102. The second locking portion 142 is located on the side of the second clamping portion 141 away from the first opening 101, that is, the second clamping portion 141 and the second locking portion 142 are arranged along the first direction X, from the first opening 101 to the second opening 102. The second locking portion 142 and the first locking portion 132 cooperate and lock.
在一些实施例中，第二锁紧部142和第一锁紧部132可以是螺纹配合锁紧。例如在第一夹紧件13设置有外螺纹形成第一锁紧部132，在第二夹紧件14设置有内螺纹形成第二锁紧部142，第一锁紧部132和第二锁紧部142螺纹配合。当第二夹紧件14处于第二位置B时，第二锁紧部142和第一锁紧部132螺纹锁紧使得第二夹紧部141和第一夹紧部131对密封部111压紧而产生形变。In some embodiments, the second locking portion 142 and the first locking portion 132 may be threadedly locked. For example, the first clamping member 13 is provided with an external thread to form the first locking portion 132, and the second clamping member 14 is provided with an internal thread to form the second locking portion 142, and the first locking portion 132 and the second locking portion 142 are threadedly locked. When the second clamping member 14 is in the second position B, the second locking portion 142 and the first locking portion 132 are threadedly locked so that the second clamping portion 141 and the first clamping portion 131 press the sealing portion 111 to cause deformation.
在一些实施例中，第二夹紧部141的最大内径不大于第二锁紧部142的内径，第一夹紧部131的最大外径不大于第一锁紧部132的外径。In some embodiments, the maximum inner diameter of the second clamping portion 141 is not greater than the inner diameter of the second locking portion 142 , and the maximum outer diameter of the first clamping portion 131 is not greater than the outer diameter of the first locking portion 132 .
在一些实施例中，第一锁紧部132也可以设置为多个夹板的部分区域。也即，第一锁紧132部也能够自适应的根据的第二锁紧部142与其的锁紧关系而形成一定的变形和对密封部的压紧关系。In some embodiments, the first locking portion 132 may also be configured as a partial area of a plurality of clamping plates. That is, the first locking portion 132 may also adaptively form a certain deformation and a pressing relationship with the sealing portion according to the locking relationship between the second locking portion 142 and the first locking portion 132 .
在一些实施例中，第二锁紧部142和第一锁紧部132也可以是卡扣配合或其他锁紧方式。In some embodiments, the second locking portion 142 and the first locking portion 132 may also be snap-fitted or locked in other ways.
在一些实施例中，第一夹紧部131和第一锁紧部132可以设置为分体式结构，也即第一夹紧件13可以是两个部件的固定结合。In some embodiments, the first clamping portion 131 and the first locking portion 132 may be configured as a split structure, that is, the first clamping member 13 may be a fixed combination of two components.
在一些实施例中，第二夹紧部141和第二锁紧部142可以设置为分体式结构，也即第二夹紧件14可以是两个部件的固定结合。In some embodiments, the second clamping portion 141 and the second locking portion 142 may be provided as a split structure, that is, the second clamping member 14 may be a fixed combination of two components.
参照图5，在一些实施例中，第二夹紧件14内壁还周向的开设有槽143，槽143位于第二夹紧部141和第二锁紧部142之间。第二夹紧部141/第二夹紧件14自第一位置A至第二位置B的状态变化时，第二锁紧部142的靠近第一口部101的端部大致的位于槽143。5 , in some embodiments, the inner wall of the second clamping member 14 is further provided with a groove 143 in the circumferential direction, and the groove 143 is located between the second clamping portion 141 and the second locking portion 142. When the second clamping portion 141/second clamping member 14 changes from the first position A to the second position B, the end of the second locking portion 142 close to the first mouth portion 101 is roughly located in the groove 143.
参照图5和图6，在本申请的实施例中，密封件11包括密封部111和延伸部112。密封件11沿第一方向X具有一定的长度，密封部111位于密封件11的一端。延伸部112朝向空腔20延伸。或者说，延伸部112自密封部111向第二口部102的方向延伸。密封件11贯通的沿第一方向X开设有通孔20d，使得空腔20与外界连通。在一些实施例中，通孔20d位于延伸部112的部分的孔径不小于第一口部102的孔径。或者说延伸部112的内径不小于第一口部101的口径。在图5中，延伸部112的内部通孔的ko孔径大致的和第一口部的孔径相等。图6中，延伸部112的内部通孔的孔径大于第一口部101的孔径。5 and 6, in an embodiment of the present application, the seal 11 includes a sealing portion 111 and an extension portion 112. The seal 11 has a certain length along the first direction X, and the sealing portion 111 is located at one end of the seal 11. The extension portion 112 extends toward the cavity 20. In other words, the extension portion 112 extends from the sealing portion 111 in the direction of the second mouth 102. The seal 11 is provided with a through hole 20d along the first direction X, so that the cavity 20 is connected to the outside world. In some embodiments, the aperture of the through hole 20d located in the extension portion 112 is not less than the aperture of the first mouth 102. In other words, the inner diameter of the extension portion 112 is not less than the aperture of the first mouth 101. In FIG. 5, the aperture ko of the internal through hole of the extension portion 112 is roughly equal to the aperture of the first mouth. In FIG. 6, the aperture of the internal through hole of the extension portion 112 is larger than the aperture of the first mouth 101.
在一些实施例中，由于第一夹紧件13、第二夹紧件14和基座12是分体式结构，可能会造成三者之间具有间隙，密封件11的延伸部112可以形成有效的密封。In some embodiments, since the first clamping member 13 , the second clamping member 14 and the base 12 are split structures, there may be gaps between them, and the extension portion 112 of the sealing member 11 can form an effective seal.
在一些实施例中，位于延伸部112、且与密封部111相反的端部周向地与空腔20的内壁紧密贴合。In some embodiments, the end portion of the extension portion 112 opposite to the sealing portion 111 is circumferentially tightly fitted to the inner wall of the cavity 20 .
在一些实施例中，参照图5，延伸部112的端部与基座12抵接。使得延伸部112将基座12与第一夹紧件的连接部密封。其中，基座12的敞口部分可以包括有台阶面122，台阶面122位于基座12的第二端12b并向腔20a凹陷，延伸部112的远离密封部111的端部可以抵接于台阶面122，使得基座12的敞口完全包覆延伸部112的端部，或者说延伸部112与基座12完全密封。进而，也由于第二夹紧件14和第一夹紧件13对密封件11形成束缚，加强了密封件11的强度以及使得密封件11更加紧密的抵接于基座12。In some embodiments, referring to FIG. 5 , the end of the extension portion 112 abuts against the base 12. The extension portion 112 seals the connection between the base 12 and the first clamping member. The open portion of the base 12 may include a step surface 122, which is located at the second end 12b of the base 12 and is recessed toward the cavity 20a. The end of the extension portion 112 away from the sealing portion 111 may abut against the step surface 122, so that the opening of the base 12 completely covers the end of the extension portion 112, or the extension portion 112 is completely sealed with the base 12. Furthermore, because the second clamping member 14 and the first clamping member 13 form a constraint on the sealing member 11, the strength of the sealing member 11 is enhanced and the sealing member 11 is more closely abutted against the base 12.
在一些实施例中，密封件11的刚度小于第一夹紧件13的刚度。In some embodiments, the stiffness of the sealing member 11 is less than the stiffness of the first clamping member 13 .
在一些实施例中，第二口部102采用多段内径依次减小的内孔形式，例如第二口部102包括朝向外部的部分102a和朝向内腔的部分102b，朝向外部的部分102a的内径大于朝向内腔的部分102b，可以使得注液喷嘴能够伸入朝向外部的部分102a并抵接于朝向内部的部分102b的过渡阶面，实现注液喷嘴与第二口部102对准，且在注液时操作稳定。In some embodiments, the second mouth portion 102 is in the form of an inner hole with multiple sections of inner diameters decreasing successively. For example, the second mouth portion 102 includes a portion 102a facing the outside and a portion 102b facing the inner cavity. The inner diameter of the portion 102a facing the outside is larger than that of the portion 102b facing the inner cavity. This allows the injection nozzle to extend into the portion 102a facing the outside and abut against the transition step surface of the portion 102b facing the inside, thereby achieving alignment of the injection nozzle with the second mouth portion 102 and stable operation during injection.
