Description

Technical Field

[0001] This invention belongs to the field of medical devices, and relates to implantable medical devices, particularly to a transdermal analyte sensor implantation system. Background Technology

[0002] Currently, most sensor implantation systems cannot be fully "ready to use immediately," meaning that secondary assembly is required before the sensor can be implanted. This increases the difficulty for users, and it is also difficult to guarantee installation accuracy when users assemble it themselves. Problems such as improper installation can easily occur during the assembly process, which will affect the overall performance and effectiveness of the device.

[0003] More concerning is that many sensor implantation systems employ dual-power systems to separately complete the implantation and release actions. These actions are typically accomplished by two independent springs, with corresponding structures designed to assist in sensor implantation. While this design achieves its intended function, its multiple drawbacks are becoming increasingly apparent. From a structural engineering perspective, dual-power systems force highly complex internal layouts and a surge in the number of components, leading to significant cumulative effects of assembly tolerances. This increases mass production difficulty and manufacturing costs, while also reducing the overall reliability of the system. From a system reliability perspective, if the device experiences power coupling misalignment or timing errors during implantation, it can lead to distorted biosignal acquisition or, in severe cases, device malfunction, posing a potential safety threat to the subject.

[0004] The aforementioned technical bottlenecks not only affect the user experience but also limit the application and promotion of such products in clinical scenarios with stringent requirements for monitoring accuracy and real-time performance. Therefore, developing a new sensor implantation system to overcome the shortcomings of existing technologies has become a key issue that urgently needs to be addressed in this field. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a transdermal analyte sensor implantation system, comprising an outer cover, a transmitter, a guide needle, and an implantation device. The implantation device comprises a transmitter base, a guide needle base, a trigger ring, and a housing, all nested together to form a storage chamber, and a single elastic ring that performs secondary storage within the storage chamber. The transmitter base includes an elastic arm and a launch well, with the transmitter housed within the launch well; the elastic arm provides a securing force to the transmitter. The guide needle is fixed to the guide needle base and extends through the implantation well, partially enclosing the sensor collection end extending from the transmitter. The outer cover is fitted onto the housing, sealing the transmitter and guide needle within the sealed environment formed by the outer cover and the housing.

[0006] Furthermore, the outer cover includes a slide, and the housing includes a switch assembly that interacts with the slide to form a sealed environment.

[0007] Furthermore, the sliding latch includes a sliding latch body, a sliding surface, and a gate locking position, and the switch assembly includes a sliding rail, a sliding ramp, a locking gate, and a sliding opening rail, with the gate locking position locked by the locking gate to form a sealed environment.

[0008] Furthermore, when the system is put into use, the sliding latch slides along the sliding rail as the outer cover rotates, and the locking position disengages from the locking grid, thus separating the outer cover from the outer shell.

[0009] Furthermore, the sliding rail includes a first sliding rail section and a second sliding rail section. When the system is in use, the sliding buckle slides along the first sliding rail section as the outer cover rotates, the gate lock position leaves the locking gate, and then the sliding buckle enters the second sliding rail section and slides along the second sliding rail section until the outer cover separates from the outer shell.

[0010] In some implementations, the energy storage cavity is composed of an energy storage platform, a shear wall, a base wall, and an energy storage seat. A single elastic ring generates a horizontal load in the energy storage cavity through the energy storage seat. The shear wall bears the horizontal load, thereby preventing the energy storage seat from giving way to the single elastic ring.

[0011] Furthermore, the trigger ring, the transmitter base, and the housing together form a trigger assembly that includes the trigger end, the elastic sail, and the sluice gate. The elastic sail is supported on the sluice gate and is located away from the trigger end to prevent the transmitter base from giving way to a single elastic ring.

[0012] Furthermore, the trigger end includes a front support rail, with the elastic sail supported on the sluice gate seat and away from the front support rail to prevent the launcher base from yielding to a single elastic ring.

[0013] Furthermore, the elastic sail includes a front support cable and a pressure beam, and the gate seat includes a shoulder and a gate opening. The pressure beam is supported on the shoulder, and the front support cable passes through the gate opening and is away from the front support rail to prevent the launcher base from giving way to a single elastic ring.

[0014] In some implementations, when the power storage seat makes way for the single elastic ring, the single elastic ring can release the second-stage power storage, causing the guide pin base to pull and retract the guide pin.

[0015] In some implementations, when the transmitter base makes way for a single elastic ring, the single elastic ring can release the first stage of stored force, causing the transmitter base to push and implant the sensor collection end; when the power storage base makes way for a single elastic ring, the single elastic ring can release the second stage of stored force, causing the guide pin base to pull and retract the guide pin.

[0016] In some implementations, the trigger end is provided with a lever rail protruding at the upper end, and a lever is also provided on the outside of the base wall, with part of the lever above the lever rail to prevent the triggering component from entering the triggering state.

[0017] Furthermore, the lever also includes a front wing, which is above the lever rail and the upper end of the lever rail abuts against a portion of the lever to prevent the trigger assembly from entering the trigger state.

[0018] Furthermore, the lever also includes a rear wing, with the front wing above the lever rail and the rear wing supported on the throttle seat to prevent the trigger assembly from entering the trigger state.

[0019] Furthermore, the gate seat includes a brake arm, with the front wing above the lever rail and the rear wing supported on the brake arm to prevent the triggering assembly from entering the triggering state.

[0020] The beneficial effects of this invention include: 1. A single-power system is designed, capable of releasing primary energy to trigger implantation and secondary energy to release and return to its original position. The release of primary and secondary energy is structurally arranged to ensure a sequential order, preventing timing errors. 2. A structure is incorporated into the trigger component to prevent accidental activation, ensuring the safety of the trigger implantation and improving the reliability of the device. 3. The structural design of the switch component provides the system with both effective sealing and ease of disassembly and use, enhancing the user experience. Attached Figure Description

Detailed Implementation Example 1

[0059] like Figure 1As shown, the transdermal analyzer sensor implantation system (hereinafter referred to as the "system") includes an outer cover 7, a transmitter 6, a guide needle 8, and an implantation device 10. The transmitter is installed in the implantation device. The partial implantation well on the transmitter and the partial implantation well in the implantation device together form an implantation well as a whole. The sensor collecting end in the transmitter extends out of the transmitter and passes through the partial implantation well located on the transmitter. The guide needle passes through the entire implantation well and partially encloses the sensor collecting end within it. The outer cover is fitted onto the outer shell of the implantation device and seals the transmitter and guide needle in the sealed environment formed by the two.

[0060] like Figure 2 As shown, the implantation device includes a transmitter base 1, a trigger ring 2, a housing 3, a guide pin base 4, and a single elastic ring 5, which are nested together to form a force-applying end and a skin-contacting end. The transmitter base includes an elastic arm and a launch well. The transmitter is housed and installed in the launch well, and the elastic arm provides a securing force to keep the transmitter in the launch well and prevent it from falling out. The transmitter base, housing, and guide pin base together form a power storage chamber, in which the single elastic ring, which completes the second stage of power storage, is housed. During the release of the first stage of power storage by the single elastic ring, the sensor collecting end can be pushed and implanted via the transmitter base. During the release of the second stage of power storage by the single elastic ring, the guide pin can be pulled and retracted via the guide pin base. Example 2

[0061] like Figure 3 As shown, the implantable device includes a force-applying end 301 on the housing 3 and a skin-contacting end 23 on the trigger ring 2, wherein the housing 3 includes a switching assembly, such as... Figure 4 The outer cover 7 shown includes a sliding latch 75. The switch assembly consists of a sliding rail 371, a sliding ramp 372, a locking gate 373, a first section of the sliding open rail 374, and a second section of the sliding open rail 375. It should be noted that the sliding ramp is an inclined surface. Figure 5As shown, there are two forms of sliding buckles. The sliding buckle 75 includes a sliding buckle body, a sliding surface 751, and a gate position 752. It should be noted that the sliding surface is a slope, and the gate position includes at least one slope that is closer to the sliding rail. The sliding buckle body enters the sliding rail from the bottom. The sliding slope and sliding surface are both inclined. Only when force is applied can the sliding surface slide over the sliding slope so that the grid position is locked by the locking grid. Thus, the outer cover and the implantation device are fixed together. That is to say, when the system is locked, the locking grid is in the grid position, and the outer shell and the outer cover form a sealed environment. When the system is used, rotate the outer cover so that the grid position is away from the locking grid. Since the side of the grid position near the sliding rail is inclined, when force is applied to the outer cover, the locking grid can easily move away from the grid position through the slope. After the grid position is away from the locking grid, the sliding buckle slides towards the first section of the sliding rail until the end of the first section of the sliding rail. The sliding buckle automatically enters the second section of the sliding rail. Pull the outer cover down and slide it in the second section of the sliding rail. When the sliding buckle slides to the end of the second section of the sliding rail, the outer cover is easily removed from the implantation device, and the outer cover and the outer shell are separated. Of course, in another embodiment, it may only include a sliding rail section. The sliding buckle slides towards the sliding rail section until the end of the sliding rail section, after which the outer cover is easily removed from the implantation device, and the outer cover and the outer shell are separated. Example 3

[0062] Based on Example 2, such as Figure 6 As shown, the outer cover 7 extends upward from the bottom to form a sealed outer cavity 711 and a sealed inner cavity 712. Only gas communication is allowed between the sealed outer cavity and the sealed inner cavity; solid or liquid communication is not permitted. The sealed outer cavity contains a desiccant, and the sealed inner cavity contains the needle implantation end of the guide needle and the sensor collection end. Specifically, the needle implantation end semi-closes and suspends the sensor collection end within the sealed inner cavity; that is, neither the needle implantation end nor the sensor collection end contacts the bottom of the sealed inner cavity. Dry air from the sealed outer cavity circulates between the sealed outer cavity and the sealed inner cavity, achieving the effect of keeping the needle implantation end and the sensor collection end dry while preventing contamination of these ends.

[0063] In another implementation, such as Figure 7 , Figure 8As shown, the outer cover 7 includes a cover body 71 and a cover body 72. The bottom surface of the cover body extends upward to form an inner cavity 701 of the cover body, including a first opening 713 and a second opening 714. The cover body includes a cover surface 721 and a cover post 722. The lower end of the cover post is connected to the cover surface, and the upper end 723 of the cover post is recessed downward to form a post well 724. The cover surface seals the first opening, and the upper end of the cover post abuts against the inner wall of the inner cavity of the cover body, so that the inner cavity of the cover body is divided into a sealed outer cavity 711 and a sealed inner cavity 712. The post well communicates with the sealed inner cavity and becomes part of the sealed inner cavity. Of course, the upper end of the cover post may not be recessed downward and the sealed inner cavity still exists. Only gas is allowed to communicate between the sealed outer cavity and the sealed inner cavity, but solid or liquid communication is not allowed. The sealed outer cavity is used to contain the desiccant, and the sealed inner cavity is used to contain the needle implantation end of the guide needle and the sensor collection end. Specifically, the needle implantation end partially encloses the sensor collection end and is suspended in the sealed inner cavity. That is to say, neither the needle implantation end nor the sensor collection end is in contact with the bottom of the sealed inner cavity. The dry air in the sealed outer cavity circulates between the sealed outer cavity and the sealed inner cavity.

[0064] like Figure 9 As shown, in a further implementation, a balancing column 74 is also provided inside the outer shell. This balancing column can extend upward from the bottom surface of the cover, or it can extend upward from the outside of the inner cavity of the cover, to support the transmitter. The number of balancing columns can be one, two, or more. Correspondingly, as... Figure 10 As shown in (b), the bottom surface of the transmitter protrudes inward to form a positioning protrusion 624, allowing the balance column in the outer shell to abut against this positioning protrusion. That is, the balance column is supported within the positioning protrusion, and the number of positioning protrusions is the same as the number of balance columns. Alternatively, the lower shell may not have positioning protrusions, and the balance column can directly abut against the lower shell. The bottom surface of the transmitter corresponding to the positioning protrusion also includes a release rail 625 extending from the positioning protrusion. The release rail allows the positioning protrusion to rotate within it during the removal of the outer shell from the implantation device, and the number of release rails is the same as the number of positioning protrusions. Example 4

[0065] like Figure 11As shown, the system includes an implantation device 10, a guide needle 8, a first sealing ring 83, a transmitter 6, a second sealing ring 73, a desiccant (not shown), and the housing 7 of Example 3. The guide needle includes a needle implantation end 81 and a needle body 82. The needle implantation end is a semi-closed needle structure, half closed and half open. The first sealing ring is fitted onto the needle body and abuts against the transmitter, thus creating a tight seal between the guide needle and the transmitter. The first sealing ring can be a finished sealing ring or a sealant formed during product manufacturing. The transmitter includes an upper housing, a lower housing, a circuit board, a sensor, and adhesive backing. The sensor collection end 642 extends out of the lower housing through a portion of the implantation well in the transmitter, and the needle implantation end extends entirely out of the lower housing through the implantation well, enclosing the sensor collection end within it. The second sealing ring is fitted onto the second opening of the outer shell and abuts against the transmitter (specifically the lower shell or the adhesive backing). In other words, the second sealing ring creates a tight seal between the outer shell and the transmitter. Alternatively, the second sealing ring creates a tight seal between the upper sealing structure and the lower sealing structure. The second sealing ring can be a finished sealing ring or a sealant formed during the product manufacturing process.

[0066] In a further embodiment, to achieve complete stability after the guide pin wraps around the sensor, such as Figure 12 As shown, a locking pin is provided on the guide pin. The figure shows the first locking pin 841 and the second locking pin 842, corresponding to, as... Figure 9 As shown, the sealed inner cavity is provided with a "7"-shaped sealing buckle 715 and an "I"-shaped limiting buckle 716. The first locking buckle and the sealing buckle 715 are engaged with each other to prevent the guide pin from shifting laterally, while the second locking buckle and the limiting buckle 716 are engaged to prevent the guide pin from shifting longitudinally.

[0067] like Figure 13 As shown, the overall system configuration is illustrated, with a tight seal between the transmitter and the outer cover via a second sealing ring 73. A first sealing ring 83 is fitted onto the guide needle and abuts against the transmitter's locking ring 67 (the locking ring is a key structural element in sealing the various components of the transmitter, and the abutment of the first sealing ring further enhances the internal sealing effect of the transmitter). The needle implantation end 81 passes through the implantation well 661, traverses the entire transmitter, partially encloses the sensor collection end 642, and extends out of the lower housing 62. The second sealing ring 73 is fitted onto the second opening of the cover and abuts against the lower housing 62 (or the adhesive backing). The cover is inserted into the housing, and the cover surface seals the first opening. The upper end of the cover column abuts against the inner wall of the housing cavity, thus dividing the housing cavity into a sealed outer cavity 711 and a sealed inner cavity 712. The desiccant 77 is contained in the sealed outer cavity 711. The needle implant end of the sensor collection end is suspended in the sealed inner cavity 712. The film 76 covers the outer side of the cover surface. The balance column 74 in the cover abuts against the positioning protrusion of the lower housing to maintain the transmitter's balanced locking state. Example 5

[0068] Based on Examples 1 to 4, the implantation device of the system will be described in more detail.

[0069] This embodiment describes the overall structure of the device by a certain orientation. The upward end is defined as the top of the outer shell, and the downward end is defined as the bottom of the outer cover. The orientation of "above" and "below" is used to describe the relative horizontal positional relationship, rather than the absolute positional relationship. like Figure 14 and Figure 15 As shown, the launcher base 1 includes a first elastic arm 11, a second elastic arm 15, a launch silo 12, a grab arm 16, a shear wall 17, an elastic sail 18, and a power storage platform 19. The launch silo is located on the first surface 13 of the launcher base, while the grab arm, shear wall, elastic sail, and power storage platform are located on the second surface 14. The first and second elastic arms are located on the sides of the launcher base, or more specifically, on the sides of the launch silo. Additionally, a portion of the launcher base has an implanted well penetrating both the first and second surfaces of the launch silo. In some embodiments, the elastic sail includes a front support cable 181 and a pressure-bearing beam 182. In some embodiments, the grab arm includes grab arm teeth 161.

[0070] like Figure 16 As shown, the first elastic arm 11 includes an arm support 114, a first hook 111, and a second hook 112. The first and second hooks are mounted on the arm support. A second push surface 102 and a third push surface 103 are also mounted on the arm support. Figure 14 In this configuration, the first hook body faces the launch silo, while the second hook body faces away from the launch silo. The first hook body 111 includes a first push surface 101 and a first hook surface 1111. The second hook body 112 includes a walkway 113, a second hook surface 1112, and a third hook surface 1113. The second and third hook surfaces are located on either side of the walkway, as are the second and third push surfaces. The second hook surface and the second push surface are positioned opposite each other, and the third hook surface and the third push surface are positioned opposite each other. Because the second hook body faces away from the launch silo, the walkway also faces away from the launch silo. Furthermore, because the second hook surface and the second push surface are opposite each other, and the third hook surface and the third push surface are opposite each other, the second and third push surfaces also face away from the launch silo. The structure of the second elastic arm is the same as that of the first elastic arm.

[0071] like Figure 17As shown, the trigger ring 2 includes a ring body 21, a trigger end 22, and a skin-contact end 23. The skin-contact end is located at the bottom of the trigger ring. The trigger end includes a front support rail 221, in which the elastic sail on the transmitter base can slide downward. In another embodiment, the trigger end also includes a lever rail 222. The first implant rail 241 and the second implant rail 242 extend on the ring body between the trigger end and the skin-contact end. Specifically, both extend from the skin-contact end to the trigger end but do not penetrate the trigger end. The first elastic arm can slide up and down in the first implant rail, and correspondingly, the second elastic arm can also slide up and down in the second implant rail. In some embodiments, the trigger end also includes an implant rail inlet. The first implant rail shown in the figure includes a first implant rail inlet 2413. Of course, other implant rails on the same trigger ring also include implant rail inlets.

[0072] like Figure 18 As shown, the outer casing 3 includes a gate seat 31 and a power storage seat 32. In some embodiments, the gate seat includes a gate arm 311, a gate shoulder 312, and a gate opening 313; however, in some embodiments, it may not include a gate arm, gate shoulder, and gate opening. In other embodiments, the outer casing also includes a reinforcing seat 33. In other embodiments, the outer casing may also consist of an outer casing body and an outer casing top cover. The top of the outer casing body has an assembly opening, and after assembly, the top cover is fitted onto the body to form a complete outer casing. In some embodiments, such as... Figure 37 As shown in (a), the aforementioned elastic sail 18, trigger end 22, and steep gate seat 31 together constitute the triggering assembly that initiates the operation of the device. The triggering assembly exhibits different states at different stages. Figure 37 (a) shows the state before operation begins. The protruding part of the elastic sail 18 is supported on and above the throttle seat, and away from the trigger end. The elastic sail does not undergo lateral displacement. Figure 37 (a) Not shown, the operating state of the triggering component is that the protruding portion of the elastic sail slides downward from the sluice gate seat and into the trigger end, then slides downward along the trigger end, resulting in lateral displacement of the elastic sail. The triggering component can also have an ending state where the elastic sail moves away from the trigger end or leaves the trigger end and then returns to it. Before the operating state, the triggering component can also have a pre-operation state where the elastic sail is not supported on the sluice gate seat and the protruding portion of the elastic sail is on the sluice gate seat. In some embodiments, such as... Figure 37 As shown in (b), the aforementioned elastic sail 18, front support rail 221, and steep gate seat 31 together constitute the triggering assembly that initiates the operation of the device. The triggering assembly exhibits different states at different stages. Figure 37 (b) shows the state before operation begins. The protruding part of the elastic sail 18 is supported on and above the sluice gate seat, and is far from the front support rail. The elastic sail has not undergone lateral displacement. Figure 37(b) Not shown, the operating state of the triggering component is that the protruding portion of the elastic sail slides downward from the sluice gate seat and enters the front support rail, then slides downward along the front support rail, resulting in lateral displacement of the elastic sail. The triggering component can also have an ending state where the elastic sail moves away from the front support rail or moves away from the front support rail and then re-enters it. Before the operating state, the triggering component can also have a preparatory state where the elastic sail is not supported on the sluice gate seat and the protruding portion of the elastic sail is above the sluice gate seat. In some embodiments, such as... Figure 19 As shown, the aforementioned front support cable 181, pressure-bearing beam 182, front support rail 221, brake shoulder 312, and gate 313 together constitute the triggering assembly that initiates the operation of the device. The triggering assembly exhibits different states at different stages. Figure 19 (a) shows the state before operation begins. The front support cable 181 of the elastic sail passes through the gate but is far from the front support rail and does not contact the front support rail. The front support cable is above the front support rail and far from the front support rail. The pressure beam 182 of the elastic sail is supported on the gate shoulder 312. The elastic sail does not undergo lateral displacement. Figure 19 (b) illustrates the operating state of the trigger assembly, where the pressure beam 182 is away from the gate shoulder 312, the front support cable 181 slides within the front support rail 221, and the elastic sail undergoes lateral displacement. Prior to the operating state, the trigger assembly can also have a pre-operational state, where the front support cable is above and away from the front support rail, and the pressure beam is supported on the gate shoulder but not in contact with it. The trigger assembly can also include a de-operational state where the elastic sail is completely below the front support rail, the overall horizontal height of the elastic sail is lower than the front support rail, or the front support cable leaves and then re-enters the front support rail but is no longer above it.

[0073] The triggering component has at least two states: not started working state and working state, or not started working state, work preparation state and working state, or not started working state, work preparation state, working state and finished working state. The first state is not started working state, the second state is work preparation state, the third state is working state, and the fourth state is finished working state.

[0074] like Figure 20As shown, the guide needle base 4 includes a needle chamber 41 and a base wall 42. In a further embodiment, it also includes a lever 43, a front wing 431, and a rear wing 432. The needle chamber is provided with latching teeth 411 corresponding to the gripping arm. The latching teeth can limit the gripping arm, and are always below the gripping arm. However, when the device is used, during the needle chamber retraction process, the latching teeth and the gripping arm can disengage, and ultimately the latching teeth are always above the gripping arm. In a further embodiment, the guide needle base also includes an eaves 421. The eaves are a limiting structure that prevents the elastic ring from disengaging from the device when the elastic ring releases the second-stage stored force during operation. Correspondingly, the guide needle base also includes a needle chamber support 422 connecting the eaves and the needle chamber. A reinforcing seat on the outer shell can correspond to and accommodate the needle chamber support. To accommodate the needle chamber support in the reinforcing seat, a support groove is formed on the reinforcing seat corresponding to the needle chamber support.

[0075] like Figure 21 As shown, the base wall, the energy storage platform, the shear wall, and the energy storage base together form a closed energy storage chamber 325. The energy storage chamber contains a single elastic ring 5 that completes the secondary energy storage. One end of the single elastic ring is supported on the energy storage platform, and the other end is supported on the energy storage base. Of course, in the initial state of the device, the closed energy storage chamber formed by the base wall, the energy storage platform, the shear wall, and the energy storage base is not necessarily completely closed; this depends on the relative positions of the gripper arm and the latching teeth. The force stored by the single elastic ring that completes the secondary energy storage can meet the displacement requirements of both the sensor implantation and the guide pin withdrawal stages. An elastic ring is a ring that releases power after pressure is applied and then removed. In specific implementations, the elastic ring can be a spring or other structures that achieve the same function. A single elastic ring generates a downward and an upward load within the storage chamber via a storage seat. The storage platform, due to the trigger assembly not being operational, bears the downward load, preventing the single elastic ring from releasing its first-stage storage. The storage seat bears the upward load, resulting in a horizontal shear force. The shear wall bears this horizontal shear force, preventing the storage seat from deforming and allowing the single elastic ring to move, thus preventing the single elastic ring from releasing its second-stage storage. During the release of the first-stage storage, the storage chamber expands as the elastic ring releases its first-stage storage downwards, creating an opening 326. The first and second elastic arms slide from the side closer to the trigger end to the side closer to the skin end within the first and second implantation rails, respectively. Figure 22 As shown, this is the situation after the elastic ring releases the first stage of stored force. The shear wall moves downward, and the storage base loses the support of the shear wall, thus gaining space for lateral deformation. The transmitter base reaches the bottom of the device during the release of the first stage of stored force by the elastic ring. In actual use, the sensor is implanted under the skin along with the transmitter base by releasing the first stage of stored force. Figure 23As shown, this is the situation after the elastic ring releases the second stage of energy storage. The energy storage cavity expands as the elastic ring releases the second stage of energy storage upwards, and the opening of the energy storage cavity increases. The energy storage seat deforms towards the center of the device due to the shear force generated during the release of the second stage of energy storage by the elastic ring. The deformation of the energy storage seat makes way for the single elastic ring, further allowing the elastic ring to complete the second stage of energy storage and pull the guide pin base to the top of the device. In this way, the device completes the release and recovery of the guide pin by releasing the second stage of energy storage during actual use. Example 6

[0076] like Figure 24 As shown, based on Embodiment 5, the trigger end further includes a lever rail 222, with the upper end 2221 of the lever rail protruding towards the center of the ring body, and a lever 43 is provided on the outer side of the base wall 42. The relative relationship between the lever, lever rail, and sluice gate seat includes at least two states: a non-started working state and a working state, or a non-started working state, a working preparation state, and a working state, or a non-started working state, a working preparation state, a working state, and a finished working state. The first state is the non-started working state, the second state is the working preparation state, the third state is the working state, and the fourth state is the finished working state. In some embodiments, in the first state, the horizontal height of the lever rail is lower than the horizontal height of part of the lever, that is, part of the lever is above the lever rail and the lever is supported on the sluice gate seat; in the third state, the lever rail slides within the lever rail. In some embodiments, in the first state, the horizontal height of the lever rail is lower than the horizontal height of a portion of the lever arm, meaning a portion of the lever arm is above the lever rail and supported on the sluice gate seat; in the second state, the lever arm disengages from the support of the sluice gate seat, and the horizontal height of a portion of the lever arm is higher than the horizontal height of the gate shoulder; in the third state, the lever rail slides within the lever rail. In some embodiments, in the first state, the horizontal height of the lever rail is lower than the horizontal height of a portion of the lever arm, meaning a portion of the lever arm is above the lever rail and supported on the sluice gate seat; in the second state, the lever arm disengages from the support of the sluice gate seat, and the horizontal height of a portion of the lever arm is higher than the horizontal height of the gate shoulder; in the third state, the lever rail slides within the lever rail; in the fourth state, the lever arm disengages from and re-enters the lever rail, and the horizontal height of the upper end of the lever rail is higher than both the horizontal height of the lever arm and the horizontal height of the sluice gate seat, meaning the upper end of the lever rail is above the lever arm, and a portion of the lever arm is above the gate shoulder. Figure 24 The left half of the diagram shows the first state, where the lever has a front wing 431 protruding towards the lever rail. The front wing is above the lever rail, and the upper end 2221 of the lever rail abuts against the lever portion below the front wing. The back of the front wing is supported on the throttle seat 31. Figure 24The right half of the diagram shows the first state, where the lever arm has a front wing 431 protruding towards the lever arm rail and a rear wing 432 protruding towards the center of the ring body. The front wing is above the lever arm rail, and the upper end 2221 of the lever arm rail abuts against the lever arm portion below the front wing, while the rear wing is supported on the gate arm of the throttle seat. Figure 25 The left half of the diagram shows the second state, where the front wing 431 abuts against the upper end 2221 of the lever rail, and the front wing is above the upper end of the lever rail. The front wing does not pass through the upper end of the lever rail before entering it. The back of the front wing is detached from the support of the gate seat, and the horizontal height of the front wing is higher than the horizontal height of the gate shoulder, meaning the front wing is above the gate shoulder. Figure 25 The right half of the diagram shows the second state, where the front wing 431 abuts against the upper end 2221 of the lever arm rail, and the front wing is above the upper end of the lever arm rail. The front wing does not pass through the upper end of the lever arm rail before entering it. The rear wing is detached from the brake arm support, and the horizontal height of the rear wing is higher than the horizontal height of the brake shoulder, meaning the rear wing is above the brake shoulder. Figure 26 The left half of the diagram shows the third state: the front wing enters the lever rail, the upper end of the lever rail is above the front wing, and the front wing is below the upper end of the lever rail. The back of the front wing is detached from the throttle seat support and is higher than the brake shoulder. Then, the front wing slides down along the lever rail and detaches from it, while the back of the front wing slides down along the brake arm and away from it. Furthermore, in the fourth state, the front wing re-enters the lever rail, and the back of the front wing is once again supported on the brake arm. Figure 26 The right half of the diagram shows the third state: the front wing enters the lever rail, with the upper end of the lever rail above the front wing and the front wing below the upper end of the lever rail. The rear wing detaches from the throttle seat support, passes over the brake arm, and rises above the brake shoulder. Then, the front wing slides down the lever rail and detaches from it, while the rear wing slides down the brake arm and moves away from it. Furthermore, in the fourth state, the front wing re-enters the lever rail, while the rear wing is once again supported on the brake arm. Figure 24 The left half and Figure 24 The right half shows two different implementation methods. Figure 25 The left half and Figure 25 The right half also has two different implementation methods. Figure 26 The left half and Figure 26 The right half also has two different implementation methods, among which, Figure 24 The left half corresponds to Figure 25 The left half corresponds to Figure 26 The left half Figure 24 The right half corresponds to Figure 25 The right half corresponds to Figure 26 The right half of it.

[0077] In another embodiment, when the aforementioned lever rail, lever, and throttle seat are all in the second state, the triggering component in embodiment 5 is in the first state. That is, when the lever rail, lever, and throttle seat are all in the first state, the triggering component cannot transition from the first state to the second state, thus preventing the triggering component from entering the triggering state. Figure 27 As shown, this is the situation before the elastic ring releases the first stage of energy storage. The energy storage chamber opens at 326 as the states of the lever rail, lever, and throttle seat change. Then, the elastic ring releases the first stage of energy storage, and the energy storage chamber expands as the elastic ring releases the first stage of energy storage downwards. The shear wall moves downwards, and the energy storage seat loses the support of the shear wall, thus gaining space for lateral deformation. The transmitter base reaches the bottom of the device during the release of the first stage of energy storage by the elastic ring. In this way, in actual use, the sensor is implanted under the skin by releasing the first stage of energy storage and reaching the skin along with the transmitter base.

[0078] It should be noted that although the brake arm and brake shoulder in the trigger component, as well as the brake arm and brake shoulder corresponding to the lever arm, exist in the same gate seat, they are not the same. The brake arm corresponding to the trigger component is defined as the first brake arm, the brake arm corresponding to the lever arm is defined as the second brake arm, the brake shoulder corresponding to the trigger component is defined as the first brake shoulder, and the brake shoulder corresponding to the lever arm is defined as the second brake shoulder. Example 7

[0079] Based on Examples 5 and 6, such as Figure 17 As shown, a stabilization window 25 is set on the trigger ring, as... Figure 18 As shown, a limiting window 34 is provided on the outer shell, and a stabilizing window 25 is open at least on the trigger end side. The stabilizing window can just enclose the limiting window, that is, the inner edge of the stabilizing window just abuts against the outer edge of the limiting window, or conversely, the limiting window can just enclose the stabilizing window, that is, the inner edge of the limiting window just abuts against the outer edge of the stabilizing window. The stabilizing window can move up and down within the range defined by the limiting window, but cannot move left and right. The stabilizing window can be set at any position on the trigger ring. When the first or second implanted rail is set in the stabilizing window, a limiting plate 343 can be set on the corresponding limiting window to further limit the range within which the implanted rail allows the elastic arm to slide up and down. This can increase the relative stability of the structure between the trigger ring and the outer shell, that is, eliminate the possibility of lateral relative movement between the trigger ring and the outer shell along the outer wall of the trigger ring and the inner arm of the outer shell.

[0080] In another embodiment, a stabilizing rail 344 is provided on the limiting window, such as... Figure 15The transmitter base shown is equipped with a stabilizing slider 145, which has a sliding groove 146. The sliding groove corresponds to the stabilizing rail and can slide in the stabilizing rail as the elastic arm slides in the implantation rail. In another embodiment, a limiting cover 345 is provided at the top of the limiting window. The limiting cover is always located above the stabilizing slider to limit the range in which the stabilizing slider can slide along the stabilizing rail.

[0081] In another embodiment, the trigger ring is provided with a first stabilizing window 251 and a second stabilizing window 252, the implantation rail is provided in the first stabilizing window, the outer shell is provided with a first limiting window 341 and a second limiting window 342, the first limiting window is provided with a limiting plate 343, the second limiting window is provided with a stabilizing rail 344, and the top of the second limiting window is provided with a limiting cover 345.

[0082] In another embodiment, the device is provided with two first stabilizing windows, two first limiting windows, four second stabilizing windows, and four second limiting windows. Each of the four second limiting windows is provided with a stabilizing rail, and the corresponding transmitter base is provided with four stabilizing sliders. The central axes of the two first stabilizing windows extending towards the center of the trigger ring coincide with each other. Similarly, the central axes of the two first limiting windows extending towards the center of the outer shell coincide with each other. The four second stabilizing windows are evenly distributed on both sides of the central axis of symmetry of the two first stabilizing windows. Similarly, the four second limiting windows are evenly distributed on both sides of the central axis of symmetry of the two first limiting windows. This is such that the two first stabilizing windows can just cover the two first limiting windows, and the four second stabilizing windows can just cover the four second limiting windows. The four stabilizing sliders can slide along the four stabilizing rails.

[0083] In another embodiment, an elastic buckle 26 is provided on the trigger ring, and a latch 35 is provided on the outer shell. The elastic buckle corresponds to the latch, wherein the latch includes a ramp forming an acute angle with the outer shell wall. When the trigger ring and the outer shell are separated and unassembled, the trigger ring and the outer shell can be assembled together by allowing the elastic buckle to contact the latch and deform over the ramp on the latch. Then, the elastic buckle returns to its original shape and locks with the latch. The latch can apply a deformation force to the elastic buckle in the direction of the trigger ring center and lock the elastic buckle, but cannot apply a deformation force to the elastic buckle in the direction of the trigger ring center and disengage the elastic buckle from the locked state. This increases the relative stability of the structure between the trigger ring and the outer shell, that is, it limits the range of longitudinal relative movement between the trigger ring and the outer shell along the outer wall of the trigger ring and the inner wall of the outer shell. Example 8

[0084] Based on Embodiments 5 and 6, the distance between the position of the elastic arm closest to the launch silo and the farthest end of the launch silo is 'a', and the distance between the nearest end and the farthest end of the launch silo is 'b'. 'a' can be greater than, equal to, or less than 'b'; in the figure, 'a' equals 'b'. The first implantation rail includes a first implantation rail gripping section and a first implantation rail release section. The second implantation rail includes a second implantation rail gripping section and a second implantation rail release section. The first and second implantation rail gripping sections are located near the trigger end, and the first and second implantation rail release sections are located near the skin-contact end. The first elastic arm can slide up and down in the first implantation rail, and correspondingly, the second elastic arm can also slide up and down in the second implantation rail. During sliding, when the corridor of the first elastic arm is located in the first implanted rail gripping section and the corridor of the second elastic arm is located in the second rail gripping section, the force applied to the first elastic arm via the second and third push surfaces of the first elastic arm causes the first elastic arm to deform toward the launch silo, and the force applied to the second elastic arm via the corresponding two push surfaces of the second elastic arm causes the second elastic arm to deform toward the launch silo, such that the distance c between the position of the first elastic arm closest to the launch silo and the position of the second elastic arm closest to the launch silo is less than b (or the first and second elastic arms do not deform, c=a); when the corridor of the first elastic arm is located in the first implanted rail release section and the corridor of the second elastic arm is located in the second rail release section, the force applied to the first elastic arm via the second and third hook surfaces causes the first elastic arm to deform away from the launch silo, and the force applied to the second elastic arm via the two hook surfaces of the same structure on the second elastic arm causes the second elastic arm to deform away from the launch silo, restoring c to b. Before the elastic ring releases the first stage of stored energy, the first and second elastic arms do not deform away from the launch silo. After the elastic ring releases the first stage of stored energy, the first and second elastic arms deform away from the launch silo, thus allowing the transmitter containing the sensor to actively detach from the launch silo. Example 9

[0085] like Figure 28 As shown, a launcher gripping and releasing mechanism for the aforementioned device is illustrated, such as... Figure 29 As shown, after placing the launcher base into the trigger ring in the direction of the thick gray arrow, the aforementioned launcher gripping and releasing mechanism is formed, with the launcher base at least partially placed within the trigger ring. The launcher gripping and releasing mechanism includes a launcher base 1 and a trigger ring 2. The launcher base includes a first elastic arm 11 and a launch well 12, and the trigger ring includes a ring body 21, a contact end 23, and a first track 241. Figure 30As shown, the first elastic arm includes a first push surface 101, a second push surface 102, a bridge 113, a first hook surface 1111, and a second hook surface 1112. The first push surface and the first hook surface are components of the first hook body 111, and the bridge 113 and the second hook surface 1112 are components of the second hook body 112. The second push surface, the first hook body, and the second hook body are mounted on the arm support 114. The distance between the position of the first elastic arm closest to the launch silo and the farthest end of the launch silo is 'a', and the distance between the nearest end and the farthest end of the launch silo is 'b'. 'a' can be greater than, equal to, or less than 'b'. Figure 29 In this case, a equals b. For example... Figure 28 As shown, the first track includes a first implanted track gripping section 2411 and a first implanted track release section 2412. The launcher base can move along the first track in the launch ring. When the corridor bridge is located in the first implanted track gripping section, the force applied to the first elastic arm via the second push surface (or arm support) causes the first elastic arm to deform toward the launch silo. The first hook 111 provides lateral fastening force to the launch silo via the first push surface 101 and longitudinal fastening force to the launch silo via the first hook surface 1111. When the corridor bridge is located in the first implanted track release section, there is no longer a force applied to the first elastic arm via the second push surface (or arm support), and the first elastic arm no longer deforms toward the launch silo. As a result, the launch silo loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface. Alternatively, when the corridor bridge is located in the first implanted track release section, the force applied to the first elastic arm via the second hook surface causes the first elastic arm to deform away from the launch silo. As a result, the launch silo loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface. Corresponding to the first elastic arm, in order to keep the transmitter base in balance during the movement in the trigger ring, the first balance surface 170 on the transmitter base and the second balance surface 245 on the trigger ring are in contact with each other, so that the corresponding ends in the trigger ring are subjected to force and do not move poorly due to uneven force.

[0086] In another implementation, the difference is, as... Figure 32As shown, the first elastic arm includes a first push surface 101, a third push surface 103, a walkway 113, a first hook surface 1111, and a third hook surface 1113. The first push surface and the first hook surface are components of the first hook body 111, and the walkway 113 and the third hook surface 1113 are components of the second hook body 112. The third push surface, the first hook body, and the second hook body are disposed on the arm support 114. When the bridge is in the first implanted rail clamping section, the force applied to the first elastic arm via the third push surface (or arm support) causes the first elastic arm to deform toward the launch silo. The first hook 111 provides lateral fastening force to the launch silo via the first push surface 101 and longitudinal fastening force to the launch silo via the first hook surface 1111. When the bridge is in the first implanted rail release section, there is no longer a force applied to the first elastic arm via the third push surface (or arm support), and the first elastic arm no longer deforms toward the launch silo. Consequently, the launch silo loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface. Alternatively, when the bridge is in the first implanted rail release section, the force applied to the first elastic arm via the third hook surface causes the first elastic arm to deform away from the launch silo. Consequently, the launch silo loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface. Example 10

[0087] Based on Example 9, such as Figure 31 As shown, the launcher base includes a first elastic arm 11, a second elastic arm 15, and a launch silo 12. The structure of the first elastic arm 11 is as follows: Figure 30 As shown, the structure of the second elastic arm is exactly the same as that of the first elastic arm. The distance between the elastic arm closest to the launch silo and the farthest point of the launch silo is 'a', and the distance between the nearest and farthest points of the launch silo is 'b'. 'a' can be greater than, equal to, or less than 'b'; in the diagram, 'a' equals 'b'. The trigger ring includes a ring body 21, a first track 241, and a second track 242. The structure of the first track is as follows: Figure 28As shown, the structure of the second track is exactly the same as that of the first track. The launcher base can move along the first and second tracks in the launch ring. When the bridge of the first elastic arm is located in the first implanted rail gripping section and the bridge of the second elastic arm is located in the second implanted rail gripping section, the forces applied to the two elastic arms by the second push surface (or arm support) of the first elastic arm and the corresponding push surface on the second elastic arm respectively cause the first and second elastic arms to deform toward the launch silo. The first hook provides lateral fastening force to the launch silo through the first push surface and longitudinal fastening force to the launch silo through the first hook surface 1111. The hook with the same structure on the second elastic arm also provides lateral fastening force to the launch silo through its push surface and longitudinal fastening force to the launch silo through its hook surface. When the bridge of the first elastic arm is located in the first implanted rail release section and the bridge of the second elastic arm is located in the second implanted rail gripping section, the forces applied to the two elastic arms by the second push surface (or arm support) of the first elastic arm and the corresponding push surface on the second elastic arm cause the first and second elastic arms to deform toward the launch silo. When the bridge is located in the second implanted rail release section, there is no longer a force applied to the first elastic arm via the aforementioned push surface (or arm support). The first and second elastic arms no longer deform toward the launch silo, and the launch silo loses the lateral and longitudinal fastening forces provided by the first and second elastic arms. Alternatively, when the bridge of the first elastic arm is located in the first implanted rail release section and the bridge of the second elastic arm is located in the second implanted rail release section, the forces applied to the two elastic arms via the hook surfaces of the same structure on the second hook surface and the second elastic arm respectively cause the two elastic arms to deform away from the launch silo, and the launch silo loses the lateral and longitudinal fastening forces provided by the first and second elastic arms.

[0088] Based on Example 9, the structure of the first elastic arm is as follows: Figure 30 or Figure 32 As shown, the structure of the second elastic arm is as follows: Figure 16 As shown. When the bridge of the first elastic arm is located in the first implanted rail gripping section and the bridge of the second elastic arm is located in the second implanted rail gripping section, the force applied to the first elastic arm via the second or third push surface of the first elastic arm causes the first elastic arm to deform toward the launch silo, and the force applied to the second elastic arm via the corresponding two push surfaces of the second elastic arm causes the second elastic arm to deform toward the launch silo; when the bridge of the first elastic arm is located in the first implanted rail release section and the bridge of the second elastic arm is located in the second implanted rail release section, the force applied to the first elastic arm via the second or third hook surface causes the first elastic arm to deform away from the launch silo, and the force applied to the second elastic arm via the two hook surfaces of the same structure on the second elastic arm causes the second elastic arm to deform away from the launch silo. This paragraph is only an example, and the state changes of the first and second elastic arms can obviously be as described in Embodiment 9.

[0089] In another embodiment, the number of elastic arms on the transmitter base can be increased to three, four, five, etc., and the number of tracks on the corresponding trigger ring that allow the elastic arms to move can also be increased to three, four, five, etc. The structures of the elastic arms can be the same or different, and the structure of the track on the trigger ring corresponds to the structure of the elastic arm moving on it. Example 11

[0090] like Figure 33 As shown, the structure of the first elastic arm 11 is as follows: Figure 30 As shown, the structure of the second elastic arm 15 is referenced. Figure 32 The structure of the second track is the same as that of the first track. When the bridge of the first elastic arm is located in the gripping section of the first implanted rail and the bridge of the second elastic arm is located in the gripping section of the second implanted rail, the force applied to the first elastic arm via the second push surface (or arm support) causes the first elastic arm to deform toward the launch silo, and the force on the second elastic arm... Figure 32 The force applied to the second elastic arm by the same push surface (or arm support) as the third push surface in the first elastic arm causes the second elastic arm to deform toward the launch silo; when the corridor of the first elastic arm is located at the first implantation rail release section and the corridor of the second elastic arm is located at the second implantation rail release section, the force applied to the first elastic arm via the second hook surface of the first elastic arm causes the first elastic arm to deform away from the launch silo, and the force applied to the second elastic arm via the same push surface (or arm support) causes the first elastic arm to deform away from the launch silo. Figure 32 The force applied to the second elastic arm by the same hook face as the third hook face causes the second elastic arm to deform away from the launch well. This paragraph is only an example; the state changes of the first and second elastic arms can obviously be as described in Example 9. Example 12

[0091] like Figure 34As shown, unlike Embodiment 9, a is less than b. When the corridor bridge is located in the first implanted rail clamping section, the first elastic arm (or the first elastic arm and the second elastic arm) maintains its original state. The first hook 111 provides lateral clamping force to the launch well through the first pushing surface 101 (or the first pushing surface of the first elastic arm and the first pushing surface of the second elastic arm), and provides longitudinal clamping force to the launch well through the first hook surface 1111 (or the first hook surface of the first elastic arm and the first hook surface of the second elastic arm). When the corridor bridge is located in the first implanted rail release section, the force applied to the first elastic arm through the second hook surface (or the force applied to the second elastic arm through the corresponding second hook surface on the second elastic arm) causes the first elastic arm (or the first... The elastic arm and the second elastic arm deform away from the launch silo, thereby causing the launch silo to lose the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface (or the launch silo loses the lateral fastening force provided by the first push surface of the first elastic arm and the first push surface of the second elastic arm, and the longitudinal fastening force provided by the first hook surface of the first elastic arm and the first hook surface of the second elastic arm). Of course, the first elastic arm and / or the second elastic arm may also include a third hook surface. This paragraph is only an example, and the state changes of the first elastic arm (or the first elastic arm and the second elastic arm) can naturally be as described in Embodiments 9 and 10. Example 13

[0092] like Figure 35 As shown, unlike Example 9, a is greater than b. When the bridge is in the first implanted rail clamping section, the force applied to the first elastic arm via the second push surface (or the force applied to the second elastic arm via the corresponding push surface on the second elastic arm) causes the first elastic arm (or the first elastic arm and the second elastic arm) to deform toward the launch silo. The first hook 111 of the first elastic arm (or the first hook of the second elastic arm) provides lateral fastening force to the launch silo via the first push surface 101 (or the first push surface of the second elastic arm) and longitudinal fastening force to the launch silo via the first hook surface 1111 (or the first hook surface of the second elastic arm). When the bridge is in the first implanted rail release section, there is no longer a force applied to the first elastic arm via the second push surface (or no longer a force applied to the second elastic arm via the corresponding push surface on the second elastic arm). The first elastic arm (or the first elastic arm and the second elastic arm) returns to its original state, and the launch silo loses the lateral fastening force provided by the first push surface of the first elastic arm (or the first push surface of the second elastic arm) and the longitudinal fastening force provided by the first hook surface of the first elastic arm (or the first hook surface of the second elastic arm). This paragraph is for illustrative purposes only. The state changes of the first elastic arm (or the first elastic arm and the second elastic arm) can naturally be as described in Embodiments 9 and 10. Example 14

[0093] This embodiment is based on embodiments 9-13.

[0094] like Figure 36 As shown, the first elastic arm includes a first gripping contact 151, which is disposed on the second push surface. When the bridge is located in the gripping section of the first implanted rail, the first gripping contact contacts the trigger ring, giving the launch well a lateral clamping force provided by the first push surface and a longitudinal clamping force provided by the first hook surface. Specifically, based on embodiments 9-11 and 13, the force applied to the first elastic arm via the first gripping contact causes the first elastic arm to deform toward the launch well, giving the launch well a lateral clamping force provided by the first push surface and a longitudinal clamping force provided by the first hook surface. Alternatively, the force applied to the second elastic arm via the first gripping contact causes the second elastic arm to deform toward the launch well, giving the launch well a lateral clamping force provided by the first push surface and a longitudinal clamping force provided by the first hook surface. Of course, the gripping contact can also be disposed on the third push surface, or gripping contacts can be disposed on both the second and third push surfaces.

[0095] In another embodiment, the first elastic arm includes a first release contact 153, which is disposed on the second hook surface of the first elastic arm. When the bridge of the first elastic arm is located in the first implanted rail release section, the first release contact contacts the trigger ring, and the launch well loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface. Specifically, based on embodiments 9-12, the force applied to the first elastic arm via the first release contact can cause the first elastic arm to deform away from the launch well, and the launch well loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface of the first elastic arm. Alternatively, the force applied to the second elastic arm via the first release contact can also cause the second elastic arm to deform away from the launch well, and the launch well loses the lateral fastening force provided by the first push surface and the longitudinal fastening force provided by the first hook surface of the second elastic arm. Of course, the release contact can also be disposed on the third hook surface of the first elastic arm, or release contacts can be disposed on both the second and third hook surfaces.

[0096] In another embodiment, the first elastic arm includes both a first gripping contact 151 and a first release contact 153. When the bridge of the first elastic arm is located in the gripping section of the first implantation rail, the first gripping contact of the first elastic arm contacts the trigger ring, and the launch well has a lateral fastening force provided by the first push surface of the first elastic arm and a longitudinal fastening force provided by the first hook surface of the first elastic arm. When the bridge of the first elastic arm is located in the release section of the first implantation rail, the first release contact of the first elastic arm contacts the trigger ring, and the launch well loses the lateral fastening force provided by the first push surface of the first elastic arm and the longitudinal fastening force provided by the first hook surface of the first elastic arm.

[0097] Overall, when the bridge of the first elastic arm is located in the first implant rail clamping section (or the bridge of the second elastic arm is located in the second implant rail clamping section), the first implant rail clamping section (or the second implant rail clamping section) keeps the first elastic arm (or the second elastic arm) with a less than b, or deforms the first elastic arm (or the second elastic arm) to achieve a less than b, thereby providing lateral clamping force (and longitudinal clamping force). When the bridge of the first elastic arm is located in the first implant rail release section (or the bridge of the second elastic arm is located in the second implant rail release section), the first implant rail release section (or the second implant rail release section) deforms the first elastic arm (or the second elastic arm) to achieve a greater than or equal to b, or restores the first elastic arm (or the second elastic arm) to a greater than or equal to b, thereby no longer providing lateral clamping force (and longitudinal clamping force). It should be noted that b can also be related to the size of the transmitter; for example, if the transmitter is a circular transmitter, b can be the diameter of the transmitter. Alternatively, if the transmitter has a notch at a position corresponding to the hook facing the launch silo, then b can be the diameter of the transmitter minus the depth of the notch. The number of times the depth of the notch is subtracted depends on the number of notches corresponding to the hook facing the launch silo. If there is only one notch, the depth of the notch is subtracted by one; if there are two notches, the depth of the notch is subtracted by two; if there are three notches, the multiple of the notch depth to be subtracted is determined according to the angle between the notches on the transmitter.
