技术领域Technical field
本申请涉及医疗器械技术领域，例如涉及一种固定释放机构及体表单元植入装置。This application relates to the technical field of medical devices, for example, to a fixed release mechanism and a body surface unit implantation device.
背景技术Background technique
对于涉及到人体代谢功能的慢性病管理，发展出一种体表植入式医疗器械技术，其是将传感器部分地植入人体进行实时监测血液或组织间液中某些化合物(如血糖、血酮、醛类、乳酸等)含量，可以精准地获取人体当前的生理状况以便采取必要的措施避免疾病的恶化。For the management of chronic diseases involving human metabolic functions, a body surface implantable medical device technology has been developed, which partially implants sensors into the human body to monitor certain compounds (such as blood sugar and blood ketones) in the blood or interstitial fluid in real time. , aldehydes, lactic acid, etc.) content, the current physiological condition of the human body can be accurately obtained so that necessary measures can be taken to avoid the worsening of the disease.
通常情况下，体表植入式医疗器械技术中采用的传感器为电化学传感器，这就需要与传感器周边部件配合使用，其中传感器周边部件包含与传感器电连接的导通部件、硅胶座、电子元器件、电源、可以容纳上述各部件的底座，和使传感器相对固定地附贴于体表双面胶等。传感器和传感器周边部件共同构成体表单元附贴于体表来实现血液或组织间液中某些化合物含量的监测。Usually, the sensors used in body surface implantable medical device technology are electrochemical sensors, which need to be used in conjunction with sensor peripheral components. The sensor peripheral components include conductive components, silicone seats, and electronic components that are electrically connected to the sensor. Device, power supply, base that can accommodate the above-mentioned components, and double-sided tape that allows the sensor to be relatively fixedly attached to the body surface, etc. The sensor and sensor peripheral components together form a body surface unit that is attached to the body surface to monitor the content of certain compounds in blood or interstitial fluid.
针对上述体表植入式医疗器械技术，目前有两种使用方式。第一种是先将传感器周边部件通过双面胶附贴于体表(例如通过手动按压的方式附贴)，然后将传感器部分地植入到皮下，再通过导通部件将传感器与电子元器件电连接。第二种是在传感器部分地植入到皮下的同时将传感器周边部件通过双面胶附贴于体表(即：在传感器部分地植入到皮下过程中植入装置同时对传感器周边部件施加垂直于体表的撞击力，所施加的力要足以让双面胶牢固附贴于体表)，其中传感器与电子元器件在植入到皮下之前已经进行预连接。There are currently two ways to use the above-mentioned body surface implantable medical device technology. The first is to first attach the sensor peripheral components to the body surface through double-sided tape (for example, by manually pressing), then partially implant the sensor under the skin, and then connect the sensor and electronic components through conductive components. Electrical connection. The second method is to attach the sensor peripheral components to the body surface through double-sided tape while the sensor is partially implanted under the skin (i.e., during the process of the sensor being partially implanted under the skin, the implantation device simultaneously exerts vertical pressure on the sensor peripheral components. The impact force on the body surface must be sufficient to make the double-sided tape firmly adhere to the body surface), in which the sensor and electronic components have been pre-connected before being implanted under the skin.
相比于第二种使用方式，尽管第一种使用方式存在些许不便，但因该方式对植入装置内部各部件复杂程度及相互间联动关系的要求要远低于第二种使用方式，因此这两种方式在实际应用中均有普遍使用。Compared with the second method of use, although the first method of use has some inconveniences, the requirements for the complexity of the internal components of the implant device and the inter-linkage relationship are much lower than those of the second method of use. Therefore, Both methods are commonly used in practical applications.
上述两种使用方式中，因传感器自身硬度不足以支撑其透过皮肤植入到人体内部，故需要借助穿刺针将传感器植入到皮下。第一种使用方式中因需要后续的将传感器与电子元器件电连接操作，通常设计成将体表单元与植入装置中的部分构件连接，如公开专利CN109998555中，将导向针与硅胶座连接，在植 入过程中导向针和穿刺针收回后形成传感器和导电橡胶电气连接。In the above two usage methods, because the sensor itself is not hard enough to support its implantation into the human body through the skin, it is necessary to use a puncture needle to implant the sensor under the skin. In the first mode of use, due to the subsequent electrical connection operation of the sensor and the electronic components, it is usually designed to connect the body surface unit to some components of the implantation device. For example, in the published patent CN109998555, the guide needle is connected to the silicone seat. , Zaizhi During the insertion process, the guide needle and puncture needle are retracted to form an electrical connection between the sensor and the conductive rubber.
相关技术中，体表单元与植入装置之间的连接是仅通过导向针与硅胶座之间的摩擦力实现连接，而无其他更稳定的固定方式，在震动的情况下会出现脱离的风险。另外，因体表单元含有双面胶，在患者进行使用时可能会出现双面胶无意粘附到其他物体表面引起体表单元从植入装置中脱落，导致医疗器械无法使用而需整体报废。In the related technology, the connection between the body surface unit and the implanted device is only achieved through the friction between the guide pin and the silicone seat. There is no other more stable fixation method, and there is a risk of detachment in the event of vibration. . In addition, because the body surface unit contains double-sided tape, when a patient uses it, the double-sided tape may accidentally adhere to the surface of other objects, causing the body surface unit to fall off from the implanted device, causing the medical device to become unusable and need to be scrapped as a whole.

本申请一实施例提供了一种固定释放机构，参阅图1和图6，第一单元1与第二单元2相互耦接，第一单元1可以被第二单元2固定或释放。当第二单元2位于如图1所述第一位置时固定第一单元1，当第二单元2位于如图6所述第二位置时释放第一单元1，其中第二单元2是朝向第一单元1的方向线性运动至第二位置的。与第二位置相比，第一位置与第一单元1的距离要远。An embodiment of the present application provides a fixing and releasing mechanism. Referring to FIGS. 1 and 6 , the first unit 1 and the second unit 2 are coupled to each other, and the first unit 1 can be fixed or released by the second unit 2 . The first unit 1 is fixed when the second unit 2 is in the first position as shown in Figure 1, and the first unit 1 is released when the second unit 2 is in the second position as shown in Figure 6, where the second unit 2 is facing the first position. A linear movement of unit 1 in the direction of the second position. The first position is further away from the first unit 1 than the second position.
参阅图1和图2，第二单元2包括基部21和位于基部21一侧的夹持部22，例如，参阅图2，夹持部22设置在所述基部21上靠近第一单元1的一侧，夹持部22包含两个夹持臂221；在一些其他实施例中，夹持臂221可以有两个以上，例如三个，或者更多个。继续参照图1，第一单元1处于第一位置时被第二单元2固定，此时夹持臂221与第一单元1的侧面相接触。Referring to FIGS. 1 and 2 , the second unit 2 includes a base 21 and a clamping part 22 located on one side of the base 21 . For example, referring to FIG. 2 , the clamping part 22 is provided on a side of the base 21 close to the first unit 1 . On the other hand, the clamping part 22 includes two clamping arms 221; in some other embodiments, there may be more than two, such as three, or more clamping arms 221. Continuing to refer to FIG. 1 , the first unit 1 is fixed by the second unit 2 when it is in the first position. At this time, the clamping arm 221 is in contact with the side of the first unit 1 .
在其他一些实施例中，夹持臂221设置为两两相对的一组或多组，夹持臂221的数量为偶数个，引导部41分别引导每组夹持臂221之间的端部距离增大，进而远离第一单元1的侧面并与之分离；在另一些实施例中，夹持臂221设置在第一单元1的外周，数量为两个或两个以上，引导部41分别引导相邻两个夹持臂221端部之间的距离增大，进而远离第一单元1的侧面并与之分离。In some other embodiments, the clamping arms 221 are arranged in one or more groups facing each other, the number of the clamping arms 221 is an even number, and the guide portion 41 guides the end distance between each group of clamping arms 221 respectively. increase, and then move away from and separate from the side of the first unit 1; in other embodiments, the clamping arms 221 are provided on the outer periphery of the first unit 1, the number is two or more, and the guide portions 41 guide respectively The distance between the ends of two adjacent clamping arms 221 increases, and further moves away from and separates from the side of the first unit 1 .
参阅图1和图2，在夹持臂221的端部还设置有锁钩，使其能够勾住第一单元1以实现更稳定的固定；相应的，在第一单元1上设置有与锁钩配合的锁槽。 Referring to Figures 1 and 2, a lock hook is also provided at the end of the clamping arm 221 so that it can hook the first unit 1 to achieve a more stable fixation; accordingly, a lock hook is provided on the first unit 1 Hook-fit locking slot.
参阅图4、图5和图11，在下壳体4上包含与夹持臂221数量相同的两个引导部41，在第二单元2位于第二位置时(将第一单元1释放)，两个引导部41设置分别与两个夹持臂221相抵接(如图11)。在其他实施例中，引导部41可以设置为一个整体，例如设置为环绕第一单元1一周，或者例如引导部41设置为非连续的多段，每段可以与两个或两个以上的夹持臂221相抵接。Referring to Figures 4, 5 and 11, the lower housing 4 includes two guide portions 41 with the same number as the clamping arms 221. When the second unit 2 is in the second position (the first unit 1 is released), the two guide portions 41 Two guide portions 41 are provided to abut against the two clamping arms 221 respectively (see Figure 11). In other embodiments, the guide part 41 may be provided as a whole, for example, it may be provided to surround the first unit 1 , or, for example, the guide part 41 may be provided as multiple non-continuous segments, and each segment may be connected to two or more clamping devices. The arms 221 are in contact.
参阅图10，此时第二单元2处于第二位置，夹持臂221通过凸起部222被下壳体4的两个引导部41引导变形(例如弹性变形)使得两个夹持臂221端部之间的距离变大，夹持臂221与第一单元1(在部分实施例中，第一单元1可以为体表单元)的侧面分离，实现第一单元1被第二单元2释放。Referring to Figure 10, at this time, the second unit 2 is in the second position, and the clamping arms 221 are guided and deformed (for example, elastically deformed) by the two guide portions 41 of the lower housing 4 through the protruding portions 222, so that the ends of the two clamping arms 221 The distance between the two parts becomes larger, and the clamping arm 221 is separated from the side of the first unit 1 (in some embodiments, the first unit 1 may be a body surface unit), so that the first unit 1 is released by the second unit 2.
从第一单元1被第二单元2固定到被释放过程中，是第二单元2在驱动力的作用下，通过位于下壳体4中的引导部41引导第二单元2的夹持臂221发生变形(弹性变形、永久变形均可)增大端部距离从而与第一单元1分离，在整个过程中，第一单元1相对于下壳体4的位置不变，可以不对第一单元1施加任何力。From the time when the first unit 1 is fixed by the second unit 2 to when it is released, the second unit 2 guides the clamping arm 221 of the second unit 2 through the guide portion 41 located in the lower housing 4 under the action of the driving force. Deformation occurs (either elastic deformation or permanent deformation is acceptable) and the distance between the ends is increased to separate from the first unit 1. During the entire process, the position of the first unit 1 relative to the lower housing 4 does not change. Apply any force.
在一实施例中，下壳体4设置有引导部41，在第二单元2从第一位置运动至第二位置时，引导部41引导夹持臂221例如做弹性变形，使得相邻两个夹持臂221之间的端部距离从第一距离切换至第二距离，第二距离大于第一距离。更详细的，相邻两个夹持臂221之间端部距离为第一距离时夹持臂221与第一单元1接触，相邻两个夹持臂221之间端部距离为第二距离时夹持臂221与第一单元1分离。In one embodiment, the lower housing 4 is provided with a guide portion 41. When the second unit 2 moves from the first position to the second position, the guide portion 41 guides the clamping arm 221 to elastically deform, for example, so that the two adjacent units 2 move from the first position to the second position. The end distance between the clamping arms 221 switches from a first distance to a second distance, the second distance being greater than the first distance. In more detail, when the distance between the ends of two adjacent clamping arms 221 is the first distance, the clamping arm 221 contacts the first unit 1, and the distance between the ends of two adjacent clamping arms 221 is the second distance. When the clamping arm 221 is separated from the first unit 1.
综合参阅图1、图6和图7，第二单元2是被驱动单元3推动并跟随其一起运动，驱动单元3则是在驱动弹簧51的驱动下沿驱动单元运动导轨52做线性运动。参阅图2和图3，第二单元2还包含卡钩23，驱动单元3还包含与卡钩23耦合的凹槽31。继续参阅图1，当第二单元2位于第一位置时，第二单元2和驱动单元3通过卡钩23和凹槽31形成临时固定关系；继续参阅图6，当第二单元2位于第二位置时，卡钩23从凹槽31中滑脱。Referring to FIGS. 1 , 6 and 7 , the second unit 2 is pushed by the drive unit 3 and moves with it. The drive unit 3 is driven by the drive spring 51 to make linear motion along the drive unit movement guide rail 52 . Referring to FIGS. 2 and 3 , the second unit 2 further includes a hook 23 , and the driving unit 3 further includes a groove 31 coupled with the hook 23 . Continuing to refer to Figure 1, when the second unit 2 is in the first position, the second unit 2 and the driving unit 3 form a temporary fixed relationship through the hook 23 and the groove 31; continue to refer to Figure 6, when the second unit 2 is in the second position position, the hook 23 slips out of the groove 31 .
在一实施例中，第二单元2从第一位置运动至第二位置具有第二行程，驱动单元3在所述第二单元2运动方向上具有第一行程。驱动单元3除了可以驱动第二单元2做线性运动之外，还可以按需求驱动其他部件，因此，第一行程和第二行程可以相同或可以不同，在一些特殊场合可以设置为第一行程大于第二行程。In one embodiment, the second unit 2 has a second stroke when moving from the first position to the second position, and the driving unit 3 has a first stroke in the movement direction of the second unit 2 . In addition to driving the second unit 2 to perform linear motion, the driving unit 3 can also drive other components as required. Therefore, the first stroke and the second stroke can be the same or different. In some special occasions, the first stroke can be set to be greater than Second trip.
在一实施例中，第一行程设置为大于第二行程时，也就意味着驱动单元3和第二单元2存在部分部件重合的可能，因此，将第二单元2的基部21设置为至少可以容纳部分驱动单元3。 In one embodiment, when the first stroke is set to be greater than the second stroke, it means that there is a possibility that some parts of the driving unit 3 and the second unit 2 overlap. Therefore, the base 21 of the second unit 2 is set to at least Accommodates part of the drive unit 3.
综合参阅图1-3和图6，第二单元2位于第一位置(图1所示的位置)时，两个卡钩23分别与两个凹槽31耦合，驱动单元3沿驱动单元运动导轨52做线性运动时推动第二单元2跟随其一起运动；第二单元2位于第二位置(图6所示的位置)时，第二单元2受限停止运动，在驱动单元3仍保持继续运动的趋势时，两个卡钩23分别从两个凹槽31中滑脱，驱动单元3可以继续运动至受限位置，驱动单元3在第二单元2受限停止运动可以继续运动能够赋予驱动单元3的其他功能，例如，可以激发或驱动其他组件的运动，例如图7中激发植入组件6执行植入动作，以将穿刺针刺穿皮肤。植入组件6可以参见公开专利CN109998555A中所描述的穿刺针，以及将穿刺针收回植入组件6内的回弹装置。在其他实施例中，驱动单元3没有其他激发或驱动需求时，可以在第二单元2受限停止运动时一同停止运动，驱动单元3具有与第二单元2相同的运动行程，此种情况无需考虑卡钩23是否从凹槽31中滑脱；驱动单元3也可以继续运动以释放驱动弹簧51的弹性势能，此种情况卡钩23需从凹槽31中滑脱。Referring to Figures 1-3 and 6, when the second unit 2 is in the first position (the position shown in Figure 1), the two hooks 23 are respectively coupled with the two grooves 31, and the drive unit 3 moves along the drive unit guide rail. When 52 makes linear motion, it pushes the second unit 2 to move with it; when the second unit 2 is in the second position (the position shown in Figure 6), the second unit 2 is restricted and stops moving, and the driving unit 3 continues to move. trend, the two hooks 23 respectively slip out of the two grooves 31, the driving unit 3 can continue to move to the restricted position, and the driving unit 3 can continue to move when the second unit 2 is restricted and stops moving, which can give the driving unit 3 Other functions, for example, can stimulate or drive the movement of other components. For example, in Figure 7, the implant component 6 is stimulated to perform an implantation action to pierce the skin with the puncture needle. The implantation component 6 can refer to the puncture needle described in the published patent CN109998555A, and the rebound device for retracting the puncture needle into the implantation component 6 . In other embodiments, when the driving unit 3 has no other excitation or driving requirements, it can stop moving together when the second unit 2 is restricted to stop moving. The driving unit 3 has the same movement stroke as the second unit 2. In this case, there is no need to Consider whether the hook 23 slips out of the groove 31; the driving unit 3 can also continue to move to release the elastic potential energy of the driving spring 51, in which case the hook 23 needs to slip out of the groove 31.
从上述第二单元2与驱动单元3的联动关系可知，驱动单元3可以具有比第二单元2更长的运动行程，在此示例中，为不影响驱动单元3在第二单元2受限停止运动后能够继续运动，第二单元2的基部21设置为与驱动单元3互不干扰，例如，可以将基部21设置为半包围例如圆弧状，可以将驱动单元3设置为可以部分地容纳在基部21的圆弧内，或者将基部21的圆弧内侧设置为与驱动单元3的至少部分边缘形状相匹配。It can be seen from the above-mentioned linkage relationship between the second unit 2 and the driving unit 3 that the driving unit 3 can have a longer movement stroke than the second unit 2. In this example, in order not to affect the driving unit 3 when the second unit 2 is limited to stop The base 21 of the second unit 2 can continue to move after the movement. The base 21 of the second unit 2 is set so as not to interfere with the drive unit 3. For example, the base 21 can be set to be semi-enclosed, such as in an arc shape, and the drive unit 3 can be set to be partially accommodated in the Within the arc of the base 21 , or the inner side of the arc of the base 21 is set to match at least part of the edge shape of the drive unit 3 .
凹槽31可以采用易于使卡钩23从中滑脱的设计，例如，图1或图3中所示的凹槽31与卡钩23接触受力面为弧形面，在一些其他实施例中接触受力面也可以为斜面，满足在卡钩23和凹槽31受力相对挤压时卡钩23从凹槽31中滑脱即可，此时卡钩23发生形变相互间的距离增大。凹槽31和卡钩23配置为成对配合使用，例如图1中所示的两对，在一些其他实施例中三对或者更多也是可以的。The groove 31 can adopt a design that makes it easy for the hook 23 to slip out of it. For example, the contact force-bearing surface of the groove 31 shown in Figure 1 or Figure 3 and the hook 23 is an arc-shaped surface. In some other embodiments, the contact force-bearing surface The force surface can also be an inclined plane, which is enough to satisfy the requirement that the hook 23 slips out of the groove 31 when the hook 23 and the groove 31 are relatively squeezed by force. At this time, the hooks 23 deform and the distance between them increases. The groove 31 and the hook 23 are configured to be used in pairs, such as the two pairs shown in FIG. 1 , and in some other embodiments, three or more pairs are also possible.
继续参阅图2，卡钩23设置于基部21上与夹持部22相对的一侧，即卡钩23和夹持臂221分别设置在第二单元2的基部21两侧。在一些其他实施例中卡钩23和夹持臂221也可以设置在第二单元2的基部21的同一侧，但需满足卡钩23和夹持臂221能够单独实施其功能且不相互形成干扰。Continuing to refer to FIG. 2 , the hook 23 is disposed on the side of the base 21 opposite to the clamping part 22 , that is, the hook 23 and the clamping arm 221 are respectively disposed on both sides of the base 21 of the second unit 2 . In some other embodiments, the hook 23 and the clamping arm 221 can also be disposed on the same side of the base 21 of the second unit 2 , provided that the hook 23 and the clamping arm 221 can independently perform their functions without interfering with each other. .
继续参阅图3，为方便制造及组装的需求，驱动单元3包含柱状体30和与柱状体30连接的附件312，凹槽31可以设置在附件312上、并靠近第二单元2一侧。在一实施例中，凹槽31可设置于驱动单元3的柱状体30上。Continuing to refer to FIG. 3 , in order to facilitate manufacturing and assembly requirements, the driving unit 3 includes a columnar body 30 and an accessory 312 connected to the columnar body 30 . The groove 31 can be provided on the accessory 312 and close to the side of the second unit 2 . In one embodiment, the groove 31 may be provided on the columnar body 30 of the driving unit 3 .
综合参阅图1、图3、图6和图7，驱动单元3安装在主体支架5的驱动单元运动导轨52上，驱动单元3的柱状体30容纳于主体支架5的空腔内，驱动 单元3还包含限位钩32，限位钩32设置在与凹槽31相对的位置，例如设置在附件312上。驱动单元3通过限位钩32与主体支架5上的限位台阶53形成临时固定的卡扣结构，在需要释放的时候利用击发按钮8挤压限位钩32使其从限位台阶53上脱落，驱动单元3在驱动弹簧51的作用力下沿着驱动单元运动导轨52朝向第二单元2做线性运动，以发挥其各种驱动力。Referring to Figure 1, Figure 3, Figure 6 and Figure 7, the drive unit 3 is installed on the drive unit movement guide rail 52 of the main body bracket 5, and the columnar body 30 of the drive unit 3 is accommodated in the cavity of the main body bracket 5. The unit 3 also includes a limiting hook 32 , which is arranged at a position opposite to the groove 31 , for example, on the accessory 312 .
