Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a locking mechanism in an implantation tool and the implantation tool. Background Art

[0002] The CGM system is a system used to monitor the blood sugar index of the human body. In the prior art, the CGM system sends a sensor into the subcutaneous tissue of the human body. The enzyme on the sensor reacts with the subcutaneous tissue fluid to detect the blood sugar value, and the blood sugar value is sent to the terminal with the transmitter, so that the real-time dynamic monitoring of blood sugar can be achieved. The CGM system only needs to be implanted once, and then the blood sugar data in the body can be continuously monitored through Bluetooth connection, eliminating the pain of frequent needle sticks of traditional blood sugar meters, and making up for the cumbersome operation of traditional blood sugar meters that can only monitor once.

[0003] When the implant tool is not in use, the components in the implant tool need to be locked to ensure the stability of the positional relationship between the components, so as to ensure that the subsequent implant tool can be used normally. After the implant tool is used, the components need to be unlocked to complete the corresponding functions.

[0045] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0046] It should be noted that when a component is referred to as "fixed to", "mounted on" or "disposed on" another component, it can be directly on the other component or indirectly disposed on the other component; when a component is "connected" to another component, or a component is referred to as "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0047] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0048] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality of" and "several" is two or more, unless otherwise specifically defined.

[0049] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the implementation conditions of the present application. Therefore, they do not have a substantial technical meaning. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present application.

[0050] The present utility model provides a locking mechanism in an implantation tool, which includes a slider and a mounting member; the mounting member abuts against the slider, and relative movement is possible between the mounting member and the slider; wherein, the mounting member has a locked state and an unlocked state after moving relative to the slider; in the locked state, the slider abuts against the mounting member to limit the form of the mounting member; in the unlocked state, the mounting member is separated from the slider, and the mounting member resumes its form. In the locking mechanism in the implantation tool, through the cooperation between the slider and the mounting member, the form of the mounting member is controlled. When the implantation tool is not in use, the slider can abut against the mounting member to limit the form of the mounting member, thereby locking the components on the mounting member; and when the implantation tool is used, after relative displacement occurs between the mounting member and the slider, the slider and the mounting member can be separated from each other, so that the mounting member resumes its form, realizing automatic unlocking of the components on the mounting member, thereby meeting the functional requirements of the implantation tool.

[0051] Please refer to Figures 1 to 7, in one embodiment, a locking mechanism 100 in an implant tool is provided, which is mainly used to implement locking and unlocking functions in the implant tool, and to achieve locking and automatic unlocking in the implant tool with fewer components to meet the functional requirements of the implant tool.

[0052] The locking mechanism 100 in the implant tool includes a slider 10 and a mounting member 20. The mounting member 20 abuts against the slider 10, and relative movement is possible between the mounting member 20 and the slider 10. Among them, the relative movement between the mounting member 20 and the slider 10 can be: the mounting member 20 moves; or the slider 10 moves; or both the mounting member 20 and the slider 10 move. That is to say, as long as a relative displacement can be generated between the mounting member 20 and the slider 10 to change the positional relationship between the mounting member 20 and the slider 10.

[0053] The mounting member 20 has a locked state and an unlocked state after the mounting member 20 moves relative to the slider 10. In the locked state, the slider 10 abuts against the mounting member 20, restricting the form of the mounting member 20. In the unlocked state, the mounting member 20 is separated from the slider 10, and the mounting member 20 resumes its form. Among them, the form of the mounting member 20 refers to: a movable structure is provided in the mounting member 20, so that the overall position state of the mounting member 20 can change accordingly. That is to say, in the locked state, the slider 10 squeezes and limits the movable structure in the mounting member 20, so that the overall position state of the mounting member 20 is maintained in a certain form; while in the unlocked state, the mounting member 20 is separated from the slider 10, and the slider 10 no longer squeezes and limits the movable structure in the mounting member 20, so that the movable structure in the mounting member 20 loses external restriction, and the movable structure in the mounting member 20 resumes its original position state.

[0054] When the locking mechanism 100 in the implant tool is applied to the implant tool, the mounting member 20 and the slider 10 can be connected and cooperated with corresponding structures in the implant tool, so as to limit or drive the mounting member 20 and the slider 10 through the corresponding structures in the implant tool, thereby making the positional relationship between the slider 10 and the mounting member 20 adapt to the use state of the implant tool. For example, when the implant tool is not in use, the slider 10 abuts against the mounting member 20 to keep the mounting member 20 in the locked state; when the implant tool is used, the corresponding structure in the implant tool drives the slider 10 and / or the mounting member 20 to move, so that the mounting member 20 is in the unlocked state; thus, the positional state of the mounting member 20 is adapted to the use state of the implant tool, thereby completing the corresponding functional role and meeting the functional requirements of the implant tool.

[0055] It can be understood that in the prior art, in order to meet the locking and unlocking of the structures in the implant tool, a large number of matching structures need to be provided, resulting in a complex overall structure of the implant tool and a large installation difficulty.

[0056] However, the locking mechanism 100 in the implant tool provided in this embodiment squeezes and limits the mounting member 20 through the slider 10, thereby restricting the shape of the mounting member 20, and can make the mounting member 20 restore its shape through the relative movement between the mounting member 20 and the slider 10, so as to realize the locking and automatic unlocking of the mounting member 20. The overall structure is simple and no additional unlocking structure needs to be provided. When the locking mechanism 100 in the implant tool is applied to the implant tool, stable locking and automatic unlocking and separation can be carried out, which can better meet the functional requirements of the implant tool. The overall structure is simpler and the installation difficulty can also be reduced.

[0057] Preferably, in one embodiment, the mounting member 20 includes a mounting member body 21 and a movable member 22, and the movable member 22 includes a movable portion 221 and an elastic portion 222. The movable portion 221 is movably arranged on the mounting member body 21, and the elastic portion 222 is connected to the movable portion 221. The elastic portion 222 refers to a component that can undergo elastic deformation after being subjected to force, and can restore to an original position state when the force is reduced or disappears. In the locked state, the slider 10 abuts against the movable portion 221, thereby limiting the position of the movable portion 221, thereby compressing the elastic portion 222. In the unlocked state, the movable portion 221 is separated from the slider 10, and the elastic portion 222 stretches to drive the movable portion 221 to move. That is to say, in this embodiment, the slider 10 specifically abuts against the moving part 221 to limit the position of the moving part 221, so as to apply force to the elastic part 222, thereby compressing the elastic part 222 and limiting the shape of the mounting member 20 to the state when the elastic part 222 is in compression; and when the slider 10 is separated from the moving part 221, the elastic part 222 stretches and resets due to its own elasticity, thereby driving the moving part 221 to move a certain distance, so that the mounting member 20 recovers its shape.

[0058] Specifically, in one embodiment, the elastic portion 222 is a spring.

[0059] Specifically, in one embodiment, the movable direction between the mounting member 20 and the slider 10 is perpendicular to the movable direction of the moving portion 221. For example, Figure 3 As shown, the movable direction between the mounting member 20 and the slider 10 is along the vertical direction, while the movable direction of the moving portion 221 is along the horizontal direction.

[0060] Specifically, when the locking mechanism 100 in the implant tool is assembled into the implant tool, the moving part 221 can be connected to the components in the implant tool, so that in the locked state, the components can be locked by the moving part 221; and in the unlocked state, the moving part 221 is driven by the elastic part 222 to move, thereby unlocking the components. For example, when the moving part 221 is in the locked state, it can be inserted into the transmitter to lock the transmitter; and in the unlocked state, it can be separated from the transmitter under the drive of the elastic part 222, thereby unlocking the transmitter; in this way, it is ensured that when the implant tool is not in use, the transmitter is stably fastened in the implant tool, and after use, the transmitter can be automatically separated from the implant tool.

[0061] Preferably, in one embodiment, after the elastic part 222 is stretched, at least part of the moving part 221 is located below the slider 10 to restrict the mounting part 20 from returning to the locked state. That is to say, when the mounting part 20 moves relative to the slider 10 to the unlocked state, at least part of the structure in the moving part 221 will move below the slider 10 under the drive of the elastic part 222, so as to cause a limit between the slider 10 and the moving part 221, making it impossible for the moving part 221 to move directly upward and return to the locked state. In this way, after the implant tool is used, the locking mechanism 100 in the implant tool cannot be directly reset, thereby avoiding the secondary use of the implant tool by the user and ensuring safety.

[0062] Specifically, in one embodiment, a limiting arm 2211 is provided on the moving part 221. In the locked state, the limiting arm 2211 abuts against the inner surface of the slider 10, and the limiting arm 2211 is limited by the slider 10; in the unlocked state, the limiting arm 2211 is located below the slider 10, so that the space for the limiting arm 2211 to move upward is blocked by the slider 10.

[0063] Preferably, in one embodiment, there are two sliders 10, and the two sliders 10 are arranged at intervals relative to each other. There are two moving parts 221, and the two moving parts 221 are arranged corresponding to the two sliders 10. That is, in the locked state, one moving part 221 abuts against one slider 10 respectively, so as to limit the two moving parts 221 respectively through the two sliders 10; while in the unlocked state, the two moving parts 221 are separated from the two sliders 10. The elastic part 222 is connected between the two moving parts 221. With this structure, the overall force can be more balanced. Further, when the moving part 221 is used to lock the components in the implant tool, the two moving parts 221 can apply forces to lock from both sides respectively, thereby improving the locking effect.

[0064] Preferably, in one embodiment, at least part of the moving part 221 extends into the elastic part 222, so as to better ensure the connection stability between the moving part 221 and the elastic part 222, and can better guide the force application directions of the two, ensuring that in the locked state, the moving part 221 smoothly compresses the elastic part 222 to the required state; while in the unlocking process, it can guide the elastic part 222 to the force application direction of the moving part 221, ensuring that the moving part 221 moves to the required position.

[0065] Specifically, in one embodiment, the movable portion 221 is provided with a connecting column 2212 , and the connecting column 2212 extends into the elastic portion 222 .

[0066] Preferably, in one embodiment, the locking mechanism 100 in the implantation tool further includes a needle cap assembly 30, and the needle cap assembly 30 includes a needle cap 31 and a needle retracting elastic member 32 connected to the needle cap 31. The needle retracting elastic member 32 refers to a member that can undergo elastic deformation after being subjected to force, and can restore to its original position when the force is reduced or disappears. The mounting member 20 includes a mounting member body 21 and a needle cap clamping arm 23 connected to the mounting member body 21, and the needle cap clamping arm 23 and the mounting member body 21 together form a locking cap cavity 24. In the locked state, the slider 10 abuts against the needle cap clamping arm 23, so that the needle cap clamping arm 23 locks the needle cap 31 in the locking cap cavity 24 and compresses the needle retracting elastic member 32. In the unlocked state, the needle cap clamping arm 23 is separated from the slider 10, and the needle retracting elastic member 32 extends to drive the needle cap 31 to move out of the locking cap cavity 24. That is to say, in the locked state, the slider 10 abuts against the needle cap clamping arm 23, thereby limiting the position of the needle cap clamping arm 23, so that the needle cap clamping arm 23 presses the needle cap 31, and the needle retracting elastic member 32 connected to the needle cap 31 is compressed. In the unlocked state, after the slider 10 is separated from the needle cap clamping arm 23, the position of the needle cap clamping arm 23 is no longer limited, so that the pressure applied by the needle cap clamping arm 23 to the needle cap 31 is less than the elastic force of the needle retracting elastic member 32, and the needle retracting elastic member 32 drives the needle cap 31 to move through its own restoring force, causing the needle cap clamping arm 23 to move and deform, so that the needle cap 31 rushes out of the locking cap cavity 24. In the implantation tool, the needle cap 31 can be connected to the implantation needle, so that when the implantation tool is not in use or during use, the position of the needle cap 31 can be limited by the needle cap clamping arm 23, thereby ensuring the stability of the position of the implantation needle and ensuring that the implantation needle can penetrate the skin. When the implantation is completed, the slider 10 can be separated from the needle cap clamping arm 23, so that the needle cap 31 can be moved to drive the implantation needle to move and complete the automatic needle withdrawal function of the implantation tool.

[0067] Specifically, in one embodiment, two needle cap clamping arms 23 may be provided, and the two needle cap clamping arms 23 apply force to the needle cap 31 from opposite sides, so as to ensure the reliability of the needle cap clamping arm 23 locking the needle cap 31. Correspondingly, a slider 10 may be correspondingly provided on the outer side of each needle cap clamping arm 23 to abut and limit the needle cap clamping arm 23.

[0068] Preferably, in one embodiment, the unlocking stroke of the needle cap locking arm 23 is greater than the unlocking stroke of the moving part 221. That is to say, in this embodiment, when both the moving member 22 and the needle cap locking arm 23 are provided in the mounting member 20, during the unlocking process, after the mounting member 20 and the slider 10 move relative to each other, the moving part 221 is first separated and unlocked from the slider 10, and then the needle cap locking arm 23 is separated and unlocked. The unlocking positions and timings of the two are different. In this way, the moving part 221 can first unlock the correspondingly connected components, and then the needle retraction operation can be performed.

[0069] Preferably, in one embodiment, a jack 25 is provided on the mounting member 20. In the locked state, the slider 10 is inserted into the jack 25. Through the setting of the jack 25, the assembly of the slider 10 can be facilitated. When the locking mechanism 100 in the implanting tool is loaded into the implanting tool, the slider 10 can be first loaded onto the mounting member 20, and then the mounting member 20 as a whole can be loaded into the implanting tool, thereby reducing the assembly difficulty.

[0070] Preferably, in one embodiment, the slider 10 includes a first blocking portion 11 and a second blocking portion 12. In the locked state, the first blocking portion 11 abuts against the moving part 221, and the second blocking portion 12 abuts against the needle cap locking arm 23. That is to say, in this embodiment, the slider 10 abuts against the structures on the mounting member 20 that need to be limited through different position areas, so as to better avoid interference between components.

[0071] Meanwhile, in one embodiment, an implantation tool 1000 is further provided, which includes a locking mechanism 100 in the implantation tool, as well as a housing 200, a driving spring 300, a driving member (not shown in the figure), and a transmitter assembly 500. The slider 10 is disposed in the housing 200, and the mounting member 20 is snap-fitted in the housing 200. Herein, "snap-fitted" means that a connection is achieved between one component and another through corresponding snap structures, and the two components can be separated from each other under corresponding conditions. The driving spring 300 is disposed between the housing 200 and the mounting member 20 to drive the mounting member 20 to move. The driving member is disposed in the housing 200 to drive the mounting member 20 to be released from the housing 200. That is, the change in the state of the mounting member 20 is driven by the driving member. Through the driving member, the mounting member 20 can be changed from the "snap-fitted" state to the "released" state, so that the mounting member 20 is separated from the housing 10. The transmitter assembly 500 is disposed on the mounting member 20. When in use, the user manipulates the driving member to release the mounting member 20, so that the driving spring 300 will drive the mounting member 20 to move, causing a relative displacement between the mounting member 20 and the slider 10, and the mounting member 20 will synchronously drive the transmitter assembly 500 to move, thereby realizing the implantation operation.

[0072] Preferably, in one embodiment, the transmitter assembly 500 is specifically connected to the moving part 221. Thus, when the implantation tool 1000 is not in use, the moving part 221 can lock the transmitter assembly 500 to ensure the connection stability between the mounting member 20 and the transmitter assembly 500. Also, after the implantation tool 1000 is used, the moving part 221 can be separated and unlocked from the transmitter assembly 500, allowing the transmitter assembly 500 to be smoothly left in the human body.

[0073] Preferably, in one embodiment, the implantation needle 501 in the transmitter assembly 500 is connected to the needle cap 31. Thus, when the implantation tool 1000 is not in use, the implantation needle 501 can be locked by the needle cap camming arm 23 to ensure that the implantation needle 501 can penetrate the skin. And after the implantation tool 1000 is used, it can automatically drive the implantation needle 501 to retract, automatically completing the function of needle retraction.

[0074] Specifically, in one embodiment, after the user presses the driving member to release the mounting member 20, the mounting member 20 drives the transmitter assembly 500 to move under the drive of the driving spring 300. After moving a certain distance, the moving part 221 first separates from the slider 10 to unlock the transmitter assembly 500, facilitating the retention of the transmitter assembly 500 on the human body. Then, after the implantation needle 501 penetrates the skin, the needle cap clamping arm 23 separates from the slider 10, causing the needle cap 31 to drive the implantation needle 501 to move back, realizing the function of retracting the needle. Since the slider 10 blocks the moving part 221, the mounting member 20 cannot be directly pushed upward, thereby preventing the secondary use of the implantation tool 1000.

[0075] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the creative concept of the present invention, but these all fall within the protection scope of the present invention.
