Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a sealing structure and implantation tool. Background Technology

[0002] CGMS (Continuous Glucose Monitoring System) is a system used for monitoring blood glucose levels in the human body. It achieves real-time dynamic monitoring of blood glucose levels by inserting sensors into the subcutaneous tissue. A typical CGMS consists of a receiver / display device, an implantation tool, and a transmitter. In use, the sensor is inserted into the subcutaneous tissue via the implantation tool, and the data detected by the sensor is transmitted through the transmitter. Users can then directly view the corresponding blood glucose data on the receiver / display device. The receiver / display device is usually a smartphone, with a specific app installed on the user's smartphone to directly receive and display the data. Alternatively, the receiver / display device can be a smartwatch or a dedicated handheld receiver.

[0003] Because the sensor needs to be implanted in the human body, it requires sterilization during the manufacturing process. Currently, one sterilization method involves assembling the sensor and implantation needle into a separate sealed structure. After sterilization, this sealed structure is then assembled into the implantation tool. Additionally, since the implantation tool needs to push the implantation needle and sensor, a corresponding pushing structure is installed within the tool. Currently, during assembly, the pushing structure is typically installed inside the tool's outer shell first, and then the sterilized sealed structure is assembled into the shell and connected to the pushing structure. This assembly and inspection process is not very convenient. Summary of the Invention

[0004] In existing implantation tools, the sealing structure and the pushing structure are two separate components, which makes assembly and inspection inconvenient. This invention provides a sealing structure that integrates the pushing structure for pushing the implantation needle into the sealing structure itself. This allows the sealing structure to have its own pushing function, eliminating the need for a separate pushing structure within the implantation tool and simplifying assembly and inspection.

The firing mechanism is used to set the implanted needle assembly and the sensor assembly, and the firing mechanism is used to drive the implanted needle assembly and the sensor assembly to move toward the opening end of the sealed cavity. The sensor assembly is detachably mounted on the firing mechanism, and the implantation needle of the implantation needle assembly passes through the firing mechanism and the sensor assembly. The trigger is disposed on the sealing body to trigger the firing mechanism, so that the firing mechanism drives the implanted needle assembly and the sensor assembly to move.

[0006] Preferably, the firing mechanism includes a firing body and a firing element; The firing body is located inside the sealed cavity, and the firing body is used to house the implanted needle assembly and the sensor assembly; The firing element is provided at one end of the firing body, and the firing element is used to drive the firing body to move toward the opening end of the sealed cavity; The sensor assembly is detachably disposed on the firing body, and the implantation needle of the implantation needle assembly passes through the firing body and the sensor assembly; The trigger is used to trigger the firing element to move the firing body.

[0010] Preferably, the opening / closing element is rotatably connected to the sealing body; The rotation axis of the opening / closing component is arranged parallel to the radial direction of the sealing body.

[0011] Preferably, the rotating shaft is disposed on one side of the opening and closing member, and a protrusion is disposed on the other side of the opening and closing member; The opening and closing component is provided with fasteners, and when the opening and closing component is closed, the fasteners are tightly attached to the inner wall of the sealing cavity.

[0012] An implantation tool includes a housing, a sealing structure as described in any one of the above-described embodiments, and a push-back component; The outer shell has an open-ended receiving space inside; The sealing structure is disposed within the accommodating space; The outer shell is provided with a locking structure, which is connected to the sealing body and is used to restrict the position of the sealing body within the receiving space. The push-back member is connected to the sealing body, and the push-back member is used to drive the sealing structure to move toward the end that is open away from the receiving space after the locking structure is unlocked.

[0013] Preferably, the implantation tool is further provided with an opening and closing mechanism, which is used to open the opening and closing mechanism when the sealing structure moves toward the end that is open away from the receiving space, so that the end of the sealing cavity that is closed by the opening and closing mechanism is open.

[0014] Preferably, the implantation tool is further provided with a trigger triggering structure, which is used to trigger the trigger after the sealing structure moves into place toward the end that is open away from the receiving space, so that the firing mechanism drives the implantation needle assembly and the sensor assembly to move.

[0015] Preferably, it also includes a transmitter, which is detachably mounted on the housing and located at one open end of the receiving space, and the transmitter is provided with a mounting slot corresponding to the position of the sensor assembly.

[0016] Preferably, the locking structure includes a firing unit and a button; The firing unit is rotatably disposed inside the housing and abuts against one end of the sealing body; The button is used to drive the firing unit to rotate, so that the firing unit separates from the sealing body.

[0017] Compared with existing technologies, the sealing structure provided by this invention includes a sealing body, a firing mechanism, and a trigger. The sealing body includes a sealing cavity with one open end. The firing mechanism is located within the sealing cavity and is used to mount an implantation needle assembly and a sensor assembly.

Furthermore, the sealing body is provided with an opening and closing component. When not in use, the opening and closing component can be used to seal and protect the sensor assembly and the implantation needle assembly, meeting the sealing requirements when not in use. At the same time, when it is needed, the opening and closing component can be opened, so that the implantation needle assembly and the sensor assembly can be implanted smoothly.

[0023] This invention provides a sealing structure comprising a sealing body, a firing mechanism, and a trigger. The sealing body includes a sealing cavity with one open end. The firing mechanism is located within the sealing cavity and is used to mount an implantation needle assembly and a sensor assembly. The firing mechanism also drives the implantation needle assembly and the sensor assembly to move toward the open end of the sealing cavity. The sensor assembly is detachably mounted on the firing mechanism, and the implantation needle of the implantation needle assembly passes through both the firing mechanism and the sensor assembly. The trigger is mounted on the sealing body and triggers the firing mechanism to move the implantation needle assembly and the sensor assembly. The sealing structure, equipped with the trigger and the firing mechanism, allows the firing mechanism to be triggered by the trigger to move the implantation needle assembly and the sensor assembly, thus enabling the sealing structure itself to have a pushing capability. This eliminates the need for a separate pushing structure in the implantation tool, simplifying the assembly and inspection of the implantation tool. Furthermore, the sealing body is provided with an opening and closing component that can be opened and closed. When not in use, the opening and closing component can be used to seal and protect the sensor assembly and the implantation needle assembly, meeting the sealing requirements when not in use. At the same time, when it is needed, the opening and closing component can be opened to allow the implantation needle assembly and the sensor assembly to be implanted smoothly.

[0024] Please refer to the following: Figures 1 to 6 In one embodiment, a sealing structure 100 is provided, which is a structure for sealing and protecting a sensor and an implantation needle. Specifically, in one embodiment, the sensor is a blood glucose sensor used in a CGMS for monitoring blood glucose levels, and the sealing structure 100 is a structure for sealing and protecting the blood glucose sensor and the implantation needle. The sealing structure 100 mainly addresses the problem that existing sealing structures typically only seal and protect the sensor and implantation needle and lack push-pull capabilities, requiring the installation of a corresponding push-pull structure in the implantation tool, resulting in a complex implantation tool structure and inconvenient assembly.

[0025] In one embodiment, the sealing structure 100 is used to install in the housing of the implantation tool and is a structure that can be sterilized independently of the implantation tool. When the implantation tool is in use, the sealing structure 100 assembles the sensor assembly onto the transmitter by cooperating with the structure in the implantation tool.

[0026] The sealing structure 100 includes a sealing body 10, a firing mechanism, and a trigger 60. The sealing body 10 primarily houses the implantation needle assembly 40 and the sensor assembly 50, providing a sealed protection for them. The firing mechanism primarily carries the implantation needle assembly 40 and the sensor assembly 50 and drives them to move, thus performing the implantation action. The trigger 60 primarily triggers the implantation action of the implantation needle assembly 40 and the sensor assembly 50.

[0027] Preferably, in one embodiment, the sealing structure 100 further includes an opening and closing member 70, which is mainly used to close and open the sealing body 10.

[0028] The sealing body 10 includes a sealing cavity 11 with one end open. The firing mechanism is located in the sealing cavity 11. The firing mechanism is used to set the implantation needle assembly 40 and the sensor assembly 50, and the firing mechanism is used to drive the implantation needle assembly 40 and the sensor assembly 50 to move toward the opening end of the sealing cavity 11.

[0029] Specifically, the implanted needle assembly 40 is located within the sealed cavity 11 and is mounted on the firing mechanism. The sensor assembly 50 is located within the sealed cavity 11 and is detachably mounted on the firing mechanism. That is, the sensor assembly 50 is not completely fixed to the firing mechanism, but rather connected using a detachable structure, allowing it to be separated from the firing mechanism after implantation. The specific form of the detachable structure of the sensor assembly 50 can be selected according to actual needs, such as using a snap-fit ​​connection or a plug-in connection. The implanted needle 41 of the implanted needle assembly 40 passes through both the firing mechanism and the sensor assembly 50.

[0030] The trigger 60 is disposed on the sealing body 10 to trigger the firing mechanism, thereby causing the firing mechanism to move the implanted needle assembly 40 and the sensor assembly 50. The opening and closing member 70 is openably and closably disposed on the sealing body 10, and the opening and closing member 70 is located at the open end of the sealing cavity 11, for sealing the sealing cavity 11. That is, the opening and closing member 70 can move relative to the sealing body 10, thereby realizing opening and closing. When the opening and closing member 70 is closed on the sealing body 10, the opening and closing member 70 completely seals the sealing body 10, isolating the sealing cavity 11 from the external environment; when the opening and closing member 70 is opened, the sealing cavity 11 can communicate with the external environment through the open end, allowing the implanted needle assembly 40 and the sensor assembly 50 to move out of the sealing cavity 11.

[0031] When the sealing structure 100 is implanted, the opening and closing member 70 can be opened first, so that one end of the sealing cavity 11 is open. Then, the firing mechanism is controlled by the trigger member 60 to drive the implantation needle assembly 40 and the sensor assembly 50 to move toward the open end of the sealing cavity 11, so as to meet the implantation requirements.

[0032] Understandably, current sealing structures typically only assemble the implantation needle and sensor, while the push structure used to push the implantation needle and sensor is not integrated into the sealing structure. Instead, the push structure is placed in the implantation tool, making the implantation tool less convenient to assemble.

[0033] In this embodiment, the firing mechanism and the trigger 60 are provided in the sealing structure 100, thereby enabling the function of pushing the implantation needle assembly 40 and the sensor assembly 50. Therefore, it is not necessary to set a corresponding pushing structure in the implantation tool, which simplifies the assembly of the implantation tool. Furthermore, the sealing body 10 is provided with an opening and closing member 70. When not in use, the opening and closing member 70 can be used to seal and protect the sensor assembly 50 and the implantation needle assembly 40, meeting the sealing requirements when not in use; at the same time, when it is needed, the opening and closing member 70 can be opened, so that the implantation needle assembly 40 and the sensor assembly 50 can be implanted smoothly.

[0034] Furthermore, since the sealing structure 100 can form a complete sterile body with implantation needles and other implantation functions, this separate sterile body can be assembled independently, allowing other structures in the implantation tool to be reused. In other words, implantation tools in the prior art are typically only usable once, while in this embodiment, since the sealing structure 100 itself has implantation functions, after the implantation tool is used, only a new sealing structure 100 needs to be replaced and assembled for reuse, making the reuse of the implantation tool possible and reducing user costs.

[0035] Furthermore, because sterilization during production involves sterilizing the entire sealing structure 100, which includes implantation functions, after sterilization, the sealing structure 100 simply needs to be installed and fixed into the implantation tool. This allows for segmented inspection during production, inspecting each assembly of the implantation tool separately. As long as the sealing structure remains intact during inspection, the tool can be used; only faulty parts need to be replaced. In contrast, current implantation tools often render the entire tool unusable if even a single faulty component is faulty.

[0036] The triggering of the trigger 60 and the opening and closing of the opening and closing of the opening and closing member 70 can be operated in conjunction with the structure in the implantation tool. The opening of the opening and closing member 70 and the triggering of the trigger 60 are realized through the structure in the implantation tool. In this way, when using the implantation tool, the user only needs to press the button on the implantation tool once to complete the entire implantation action.

[0037] Preferably, in one embodiment, the firing mechanism includes a firing body 20 and a firing element 30. The firing body 20 is located within the sealed cavity 11, and the firing element 30 is disposed at one end of the firing body 20. The firing element 30 is used to drive the firing body 20 toward the opening end of the sealed cavity 11. The firing body 20 is used to house an implantation needle assembly 40 and a sensor assembly 50. The sensor assembly 40 is detachably disposed on the firing body 20, and the implantation needle 41 of the implantation needle assembly 40 passes through the firing body 20 and the sensor assembly 50. The trigger 60 is used to trigger the firing element 30 to drive the firing body 20 to move. That is, in this embodiment, the firing body 20 is a component for carrying the implantation needle assembly 40 and the sensor assembly 50, while the firing element 30 is a component for providing driving force to drive the implantation needle assembly 40 and the sensor assembly 50 to move. The firing element 30 moves the firing body 20, thereby simultaneously moving the implanted needle assembly 40 and the sensor assembly 50. The trigger element 60 is used to trigger the firing element 30, causing the firing element 30 to provide driving force to the firing body 20.

[0038] In one embodiment, the firing element 30 may be a spring, and the spring force is used to drive the firing body 20.

[0039] Specifically, in one embodiment, the firing element 30 is located within the sealed cavity 11, at one end near the trigger 60. The firing element 30 is a compression spring, and its two ends abut against the sealing body 10 and the firing body 20, respectively. When the sealing structure 100 is not in use, the firing element 30 is in a compressed and restricted state. When unlocked by the trigger 60, the firing element 30 is no longer restricted and begins to extend, thereby driving the firing body 20 to move toward the open end of the sealed cavity 11. Of course, in other embodiments, the specific location and form of the firing element 30 can be selected according to actual needs. For example, a tension spring can also be selected, as long as it can provide the driving force to move the firing body 20.

[0040] Preferably, in one embodiment, the trigger 60 is detachably connected to the implanted needle assembly 40. The trigger 60, by separating from the implanted needle assembly 40, controls the firing element 30 to move the firing body 20. That is, in this embodiment, the trigger 60 is connected to the implanted needle assembly 40, and this connection is detachable. When the trigger 60 is connected to the implanted needle assembly 40, the trigger 60 can pull the implanted needle assembly 40, thereby restricting the firing element 30 and causing it to compress. When the trigger 60 is separated from the implanted needle assembly 40, the firing element 30 is no longer restricted and begins to extend. The specific detachable connection structure between the trigger 60 and the implanted needle assembly 40 can be selected according to actual needs, as long as the trigger 60 and the implanted needle assembly 40 can smoothly separate when the firing element 30 needs to extend.

[0041] Preferably, in one embodiment, the trigger 60 is rotatably disposed on the sealing body 10, and the trigger 60 is separated from the implantation needle assembly 40 by rotation. That is, in this embodiment, the trigger 60 and the implantation needle assembly 40 are specifically separable by rotation. The trigger 60 and the implantation needle assembly 40 are connected by a rotational locking mechanism, where rotational locking means that one component is fastened to another component by rotation. Forward rotation of this component locks it to the other component, while reverse rotation unlocks it. For example, the trigger 60 and the implantation needle assembly 40 are connected via a rotating platform structure. The top of the implantation needle assembly 40 may be provided with a platform, while the trigger 60 may have a slot. When the platform is screwed into the slot, the slot wall restricts the platform, preventing axial separation between the implantation needle assembly 40 and the trigger 60. Rotation is required to disengage the platform from the slot, thus enabling axial separation between the implantation needle assembly 40 and the trigger 60. Of course, in other embodiments, the detachable connection structure between the trigger 60 and the implantation needle assembly 40 can be other structural forms, such as using a snap-fit ​​structure. The requirement is that the implantation needle assembly 40 can be stably connected to the trigger 60 when not in use, and that the trigger 60 can smoothly separate from the implantation needle assembly 40 when the firing element 30 needs to extend.

[0042] Specifically, in one embodiment, the rotation center axis of the trigger 60 is parallel to the axial direction of the sealing body 10.

[0043] Specifically, in one embodiment, the implanted needle assembly 40 includes the implanted needle 41 and a needle tip 42 connected to the implanted needle 41. The needle tip 42 is detachably connected to the trigger 60 and is disposed on the firing body 20.

[0044] Preferably, in one embodiment, the trigger 60 is disposed on the other end of the sealing body 10 opposite to the opening / closing member 70, and the trigger 60 extends into the sealing cavity 11. That is, the opening / closing member 70 is disposed at one end of the sealing body 10, and the trigger 60 is disposed at the other end of the sealing body 10. One end of the sealing body 10 is the open end of the sealing cavity 11, and the opening / closing member 70 is disposed at this open end of the sealing cavity 11. For example, as... Figure 2 As shown, the bottom of the sealing cavity 11 is open, the opening and closing member 70 is closable at the bottom of the sealing body 10, and the trigger member 60 is disposed at the top of the sealing body 10. By inserting the trigger member 60 into the sealing cavity 11, it is convenient to connect the implantation needle assembly 40 with the trigger member 60.

[0045] It is understandable that, since the trigger 60 needs to extend into the sealing cavity 11, a through hole needs to be provided at the corresponding position of the sealing body 10 to allow the trigger 60 to extend into it. Due to the opening of the through hole, there is a possibility that contaminants may enter the sealing cavity 11 at this location. Preferably, in one embodiment, the sealing structure 100 further includes a sealing element 80, which is disposed between the trigger 60 and the sealing body 10 to seal the other end of the sealing body 10, thereby better ensuring the sealing performance of the sealing body 10 and ensuring that the sealing cavity 11 is not contaminated.

[0046] Furthermore, to better ensure a sealing effect, the sealing element 80 is made of annular sealing soft rubber material, which can be deformed by compression to ensure a sealing effect. Specifically, the sealing element 80 can be a rubber stopper.

[0047] Preferably, in one embodiment, the opening / closing member 70 is rotatably connected to the sealing body 10. That is, in this embodiment, the opening / closing member 70 is rotatably mounted on the sealing body 10, and the opening / closing member 70 can be opened and closed by rotation. Of course, in other embodiments, the specific opening / closing form of the opening / closing member 70 can be other structural forms. In this embodiment, the opening / closing is achieved by rotation, which facilitates cooperation with corresponding structures in the implantation tool. This allows the implantation tool to have corresponding structures to automatically control the opening / closing member 70, eliminating the need for manual operation and simplifying the use of the implantation tool.

[0048] Preferably, in one embodiment, the rotation axis 71 of the opening / closing member 70 is arranged parallel to the radial direction of the sealing body 10. This allows the opening / closing member 70 to be opened by flipping, enabling it to open in a "flip-top" manner. This facilitates the design of an automatic control mechanism for opening the opening / closing member 70 within the implantation tool. With this structural design, only a blocking structure is needed in the implantation tool to block the opening / closing member 70. The opening of the opening / closing member 70 is automatically achieved by axially moving the sealing structure 100 as a whole, further enhancing the design of the implantation tool.

[0049] Preferably, in one embodiment, the rotating shaft 71 is disposed on one side of the opening / closing member 70, and a protrusion 72 is disposed on the other side of the opening / closing member 70. The protrusion 72 facilitates the corresponding structure in the implantation tool to flip and open the opening / closing member 70.

[0050] Preferably, in one embodiment, the opening / closing member 70 is provided with a fastener 73. When the opening / closing member 70 is closed, the fastener 73 is tightly attached to the inner wall of the sealing cavity 11, thereby preventing the opening / closing member 70 from accidentally opening through friction. The main function of the fastener 73 is to improve the stability of the connection between the opening / closing member 70 and the sealing body 10 when the opening / closing member 70 is closed, ensuring that the opening / closing member 70 will not open accidentally. Specifically, the fastener 73 can be fastened to the inner wall of the sealing cavity 11 by an interference fit. The fastener 73 can be made of a material with a certain elastic deformation capability, and the outer diameter of the fastener 73 can be slightly larger than the aperture of the sealing cavity 11.

[0051] Preferably, in one embodiment, when the opening / closing member 70 is closed, it is tilted onto the sealing body 10. It is understood that since the opening / closing member 70 is opened by flipping, it requires a certain amount of space during this process within the implantation tool, and the internal space of the implantation tool is limited. By tilting the opening / closing member 70, the space required for it to fully open can be reduced, allowing for better adaptation to the limited internal space of the implantation tool and also facilitating miniaturization of the implantation tool.

[0052] Preferably, in one embodiment, the sealing structure 100 further includes a needle retraction member 90, which is disposed within the sealing body 10 and connected to the implanted needle assembly 40. The main function of the needle retraction member 90 is to drive the implanted needle assembly 40 toward the end closer to the trigger member 60, thereby achieving automatic needle withdrawal. It can be understood that when the firing member 30 drives the implanted needle assembly 40 into position, after the implanted needle 41 pierces the human body, only the sensor assembly 50 and the transmitter need to remain in the human body, while the implanted needle 41 needs to be withdrawn. The needle retraction member 90 mainly drives the implanted needle assembly 40 back after the implanted needle 41 pierces the body, thereby achieving automatic needle withdrawal. In other words, in this embodiment, the sealing structure 100 also integrates an automatic needle withdrawal function, thus eliminating the need for a needle withdrawal structure in the implantation tool, further simplifying the structure of the implantation tool and its assembly. Specifically, in one embodiment, the needle withdrawal member 90 can be a tension spring, with both ends of the tension spring connected to the sealing body 10 and the needle tip 42 respectively. Thus, when the implantation needle assembly 40 moves into place, the tension spring pulls back the implantation needle assembly 40, thereby realizing the automatic withdrawal of the implantation needle 41.

[0053] In one embodiment, an implantation tool 1000 is also provided, comprising a housing 200, the sealing structure 100, and a push-back member 300. The housing 200 has an open-ended receiving space 220, referred to as an opening 210 for ease of description. The sealing structure 100 is disposed within the receiving space 220, and the opening / closing member 70 is located near the opening 210. A locking structure 400 is provided on the housing 200, connected to the sealing body 10, and used to restrict the position of the sealing body 10 within the receiving space 220. The push-back member 300 is connected to the sealing body 10, and used to move the sealing structure 100 away from the opening 210 after the locking structure 400 is unlocked.

[0054] When the implantation tool 100 is not in use, the locking structure 400 is in the locked position, thereby restricting the position of the sealing body 10 and preventing the push-back member 300 from moving the sealing structure 100. When the user manipulates the locking structure 400 to the unlocked position, the locking structure 400 separates from the sealing body 10, and the push-back member 300 is no longer restricted, allowing it to move the sealing structure 100 in the opposite direction (away from the opening 210).

[0055] Understandably, in existing implantation tools, a pusher is usually set inside the implantation tool, and the sealing structure is set on the pusher. A drive spring is connected to the pusher. After the implantation tool is unlocked, the drive spring will drive the pusher to move forward toward the opening of the implantation tool.

[0056] The implantation tool 1000 provided in this embodiment differs from the prior art in that the implantation tool 1000 provided in this embodiment no longer has a pusher, and the reverse pusher 300 directly pushes the sealing structure 100. After the implantation tool 1000 is unlocked, the reverse pusher 300 drives the entire sealing structure 100 to move in the opposite direction to realize the implantation action.

[0057] Specifically, in one embodiment, the implantation tool 1000 is an implantation tool applied in CGMS.

[0058] Specifically, in one embodiment, the sealing body 10 is provided with an outwardly protruding extension wall 12. The pusher 300 abuts against the surface of the extension wall 12 near the opening 210, while the locking structure 400 abuts against the surface of the extension wall 12 away from the opening 210. That is, the pusher 300 and the locking structure 400 abut against two opposite surfaces of the extension wall 12, so that the locking structure 400 restricts the position and shape of the pusher 300 by pressing the extension wall 12.

[0059] In one embodiment, the thrust member 300 may be a spring, and the spring force is used to drive the sealing structure 100.

[0060] Specifically, in one embodiment, the thrust member 300 is a compression spring.

[0061] Preferably, in one embodiment, the implantation tool 1000 is further provided with an opening and closing structure 500. The opening and closing structure 500 is used to open the opening and closing member 70 when the sealing structure 100 moves away from the opening 210, so that the end of the sealing cavity 11 closed by the opening and closing member 70 is opened. That is, in this embodiment, the implantation tool 1000 can automatically open the opening and closing member 70 during use, eliminating the need for manual operation by the user. When the sealing structure 100 is moved by the pusher 300, the opening and closing member 70 can be directly opened by the opening and closing structure 500, thereby simplifying user operation.

[0062] Specifically, in one embodiment, the opening structure 500 of the opening and closing member is a blocking structure. When the pusher 300 drives the sealing structure 100 to move in the opposite direction, the opening structure 500 is located on the path of movement of the opening and closing member 70. Therefore, when the opening and closing member 70 moves to a certain position, it will be blocked by the opening structure 500, thereby opening the opening and closing member 70. More specifically, the opening structure 500 is located on the path of movement of the protrusion 72, blocking the protrusion 72 to open the opening and closing member 70.

[0063] Preferably, in one embodiment, the implantation tool 1000 is further provided with a trigger triggering structure 600. The trigger triggering structure 600 is used to trigger the trigger 60 after the sealing structure 100 moves into place in a direction away from the opening 210, so that the firing member 30 drives the firing body 20 to move. That is to say, in this embodiment, the implantation tool 1000 can also automatically trigger the trigger 60 during use, realizing automatic triggering of the sealing structure 100, eliminating the need for additional manual operation by the user. The sealing structure 100 is driven by the pusher 300. When the sealing structure 100 moves into place, the trigger triggering structure 600 can be directly triggered to realize automatic implantation operation, thereby simplifying user operation, allowing each user to complete the entire use action by operating the locking structure 400 only once.

[0064] Specifically, in one embodiment, the trigger structure 600 is used to drive the trigger 60 to rotate, thereby triggering the trigger 60. More specifically, in one embodiment, the outer peripheral surface of the trigger 60 is provided with a spirally extending trigger protrusion 61, and the trigger structure 600 is provided with a stop or a guide groove. When the trigger 60 moves to the trigger structure 600, the stop or the guide groove blocks and guides the trigger protrusion 61, thereby using the power of the moving sealing structure 100 to drive the trigger 60 to rotate, thereby triggering the trigger 60 and separating the needle 42 from the trigger 60.

[0065] Specifically, in one embodiment, the trigger structure 600 is located directly above the trigger 60.

[0066] Specifically, in one embodiment, the trigger structure 600 can be integrated on the housing 200, and the trigger 60 can be triggered by directly opening the trigger structure 600 on the housing 200.

[0067] Preferably, in one embodiment, the outer shell 200 includes an outer shell body 230 and a fixing member 240. The outer shell body 230 has the opening 210 and the receiving space 220. The fixing member 240 is fixed inside the outer shell body 230 and located at the opening 210. The opening and closing member opening structure 500 is integrated on the fixing member 240, and the opening and closing member 70 is opened by directly opening the opening and closing member opening structure 500 on the fixing member 240. By setting the fixing member 240 and integrating the opening and closing member opening structure 500 on the fixing member 240, the design difficulty of the opening and closing member opening structure 500 can be reduced, and the assembly difficulty of the implantation tool 1000 can also be reduced. When assembling the implantation tool 1000, the sealing structure 100 can be assembled into the outer shell body 230 first, and then the fixing member 240 can be assembled, which can better prevent the sealing structure 100 from being accidentally opened.

[0068] Specifically, in one embodiment, the two ends of the thrust member 300 abut against the fixing member 240 and the extension wall 12, respectively.

[0069] Preferably, in one embodiment, the implantation tool 1000 further includes a transmitter 700, which is detachably mounted on the housing 200 and located at the opening 210. The transmitter 700 is provided with a mounting groove 710 corresponding to the position of the sensor assembly 50.

[0070] In other words, in this embodiment, when the implantation tool 1000 is not in use, the sensor assembly 50 and the transmitter 700 are not assembled together. The sensor assembly 50 needs to be assembled into the transmitter 700 using the implantation tool 1000. After the implantation tool 1000 is used, the firing body 20 moves the sensor assembly 50 toward the opening 210, thereby assembling the sensor assembly 50 into the mounting slot 710. The electrical connection points on the sensor assembly 50 are then connected to the electrical connection points on the transmitter 700, thus realizing the assembly between the sensor assembly 50 and the transmitter 700.

[0071] Specifically, in one embodiment, the sensor assembly 50 includes a base 51 and a sensor 52 disposed on the base 51. A latching structure is provided between the base 51 and the transmitter 700. When the base 51 is inserted into the mounting groove 710, the base 51 is fixed in the mounting groove 710 by the latches. For example, a latching groove may be provided on the base 51, and a corresponding latch may be provided on the groove wall of the mounting groove 710. Thus, when the base 51 is pushed into the mounting groove 710, the base 51 is fixed in the mounting groove 710 by the latching groove, thereby ensuring that the base 51 will not accidentally detach from the transmitter 700. More specifically, in one embodiment, the base 51 includes a sensor sealing upper cover 511 and a sensor sealing lower cover 512.

[0072] Preferably, in one embodiment, the locking structure 400 includes a firing unit 410 and a button 420. The firing unit 410 is rotatably disposed within the housing 200 and abuts against one end of the sealing body 10 (specifically against the extension wall 12). The button 420 is used to drive the firing unit 410 to rotate, thereby separating the firing unit 410 from the sealing body 10. That is, in this embodiment, the user can press the button 420 to apply force to the firing unit 410, causing the firing unit 410 to rotate and separate from the sealing body 10, thus enabling the use of the implantation tool 1000.

[0073] Specifically, in one embodiment, the firing unit 410 adopts a stop arm structure that is rotatably disposed within the housing 200.

[0074] Specifically, in one embodiment, multiple firing units 410 are provided, so that they can abut against the sealing body 10 from multiple directions, thereby better ensuring the accuracy of the position of the sealing body 10 and preventing the sealing body 10 from deviating.

[0075] Specifically, in one embodiment, the firing unit 410 is rotatably disposed within the housing 200 via a connecting shaft 4101.

[0076] Specifically, in one embodiment, the firing unit 410 and the button 420 are engaged by inclined surfaces. This structure makes it easier and more convenient for the user to press the button 420. After pressing the button 420, the engagement between the two inclined surfaces converts the downward pressure into an inclined component force that drives the firing unit 410 to rotate, so that the user does not encounter significant resistance when pressing, making it easier to press and use the implantation tool 1000.

[0077] Preferably, in one embodiment, the implantation tool 1000 further includes a protective cover 800, which is detachably connected to the outer shell 200 and closes the opening 210. The protective cover 800 better protects and seals the structure inside the outer shell 200. When using the implantation tool 1000, the user needs to remove the protective cover 800 before use.

[0078] In one embodiment, the implantation tool 1000 operates as follows: when the button 420 is pressed, the inclined surface of the button 420 and the inclined surface of the firing unit 410 generate an oblique component force, which causes the firing unit 410 to rotate. After the firing unit 410 rotates, it separates from the sealing body 10. At this time, the pusher 300 drives the entire sealing structure 100 to move upwards. During this movement, the opening structure 500 blocks the opening member 70, causing the opening member 70 to flip open. As the sealing structure 100 continues to be impacted by the inertia of the pusher 300, the trigger 60 collides with the trigger trigger structure 600, causing the trigger 60 to rotate, thereby disengaging the trigger 60 from the needle 42. Under the action of the firing element 30, the firing body 20, the implantation needle assembly 40, and the sensor assembly 50 are driven to impact downwards until the sensor assembly 50 engages with the transmitter 700 (at this time, the implantation needle 41 and the sensor 52 have been implanted into the human body), and the entire implantation action is completed.

[0079] The implantation tool 1000 simplifies user operation, allowing users to complete the entire implantation process with a single click. Furthermore, the integrated design of the sealing structure 100 facilitates sterilization using gamma sterilization. It also simplifies overall assembly, as the functions for pushing and withdrawing the needle are fully integrated into the sealing structure 100, making reassembly after sterilization simple and enabling segmented inspection.

[0080] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
