Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an auxiliary implanting device. Background Art

[0002] With the gradual improvement of the living standards of residents, people are becoming more and more concerned about their own health conditions. Based on this, body sensor devices are increasingly used in people's daily lives. When in use, the body sensor device is implanted into the user's surface skin, and the sensor device is used to detect the blood in the user's body, so as to calculate the index values related to the user's health.

[0003] Currently, when implanting a body sensor device into the human body, it usually needs to be assisted by an implanting device. In order to reduce the product use cost, the auxiliary implanting device is designed in a reusable form. However, when the user finishes using it, since some structures (such as the guide needle, the bracket for fixing the sensor device, etc.) will remain in the auxiliary implanting device, if the user does not remove the remaining structures, it may cause damage to the auxiliary implanting device during the next use. Summary of the Invention

[0004] This application provides an auxiliary implanting device, which can facilitate the removal of the structures remaining in the auxiliary implanting device after implanting the sensor device into the human body.

[0008] The housing includes an upper shell and a lower cover arranged along the axis direction of the housing, and the upper shell and the lower cover are detachably connected;

[0009] The lower cover is provided with a connection structure and a guide needle separation structure. When the lower cover is assembled with the upper shell connected to the module bracket, the connection structure is used to fix to the module bracket, so that when the lower cover is separated from the upper shell in a state where the connection structure is fixed to the module bracket, the module bracket is driven to separate from the injection module, and the guide needle separation structure is used to drive the guide needle to loosen from the clamping module, so that the guide needle falls into the lower cover.

[0010] For the auxiliary implantation device provided in this application, the housing is designed as a detachable upper shell and a lower cover, and a connection structure and a guide needle separation structure are arranged in the lower cover. After the sensor device is implanted, the module bracket is connected to the injection module, and the guide needle is clamped by the clamping module. At this time, the lower cover and the upper shell are assembled, so that the connection structure is relatively fixed to the module bracket, and the guide needle separation structure is used to make the guide needle loosen from the clamping module. Subsequently, the lower cover and the upper shell are separated again, and the module bracket and the guide needle can be removed from the injection module. Thus, the auxiliary implantation device in this application can use its own structure to take out the structure remaining on the injection module, so as to facilitate the reuse of the auxiliary implantation device and avoid damage to the auxiliary implantation device.

[0011] In some possible implementation schemes, the connection structure includes at least one first buckle arranged on the bottom wall of the lower cover, and the module bracket is provided with at least one abutting buckle.

[0014] In some possible implementation schemes, the clamping module includes two clamping rods, and the clamping rods are arranged obliquely to the axis direction of the housing, so that the ends of the two clamping rods are close to each other to clamp the guide needle.

[0015] In some possible implementation schemes, the guide needle separation structure includes a return needle ejector rod arranged on the bottom wall of the lower cover, and the return needle ejector rod extends along the axis direction of the housing;

[0016] When the lower cover is assembled with the upper shell, the return pin ejector rod is used to drive the ends of the two clamping rods away from each other, so that the guiding needle is disengaged from the clamping module.

[0017] In some possible embodiments, there are two return pin ejector rods, and the two return pin ejector rods are arranged in one-to-one correspondence with the two clamping rods;

[0018] A groove with an opening facing the lower cover is provided at the bottom of each clamping rod, and a convex portion is provided at the top of each return pin ejector rod. When the lower cover is assembled with the upper shell, at least a part of the convex portion is located in the groove respectively.

[0019] In some possible embodiments, the two return pin ejector rods are arranged at intervals, and the guiding needle separating structure further includes a magnetic attraction structure, and the magnetic attraction structure is arranged between the two return pin ejector rods.

[0020] In some possible embodiments, the injection module includes a return pin bracket, and the clamping module is connected to the return pin bracket;

[0021] The return pin bracket can move relative to the axis direction of the housing, so as to take out the guiding needle from the sensor device through the clamping module.

Detailed implementation

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Reference Figure 1 In this embodiment, the auxiliary implantation device in the embodiments of the present application may include a housing 205 and an injection module 206 disposed within the housing 205. Among them, the bottom of the injection module 206 can be used to connect to the sensor module. The injection module 206 can move relative to the housing 205 along the axis direction of the housing 205 to drive the sensor module to move relative to the housing.

[0044] The sensor module in this embodiment may include a module bracket 120, a sensor device ( Figure 1 not shown in the figure), and a guide pin 140. Among them, the sensor device is detachably connected to the module bracket 140, the guide pin 140 is detachably connected to the sensor device, and the module bracket 120 is detachably connected to the injection module 206.

[0045] The injection module 206 includes a clamping module 211 which can be used to clamp the guiding needle 140. When the injection module 206 is connected to the module bracket 120, the clamping module 211 clamps the guiding needle 140, and the relative position between the guiding needle 140 and the clamping module 211 is fixed.

[0046] It can be understood that the injection module 206 in this embodiment can be used to drive the sensor module to move so that the sensor device is implanted into the human body. After the implantation is completed, the module bracket 120 can be separated from the sensor device, and the guiding needle 140 can be separated from the sensor device so that the sensor device remains in the human body. At this time, the module bracket 120 and the guiding needle 140 remain in the auxiliary implantation device 200.

[0047] The housing 205 includes an upper shell 240 and a lower cover 250 arranged along the axis direction of the housing 205, and the upper shell 240 and the lower cover 250 are detachably connected. Before the injection module 206 and the module bracket 120 are assembled, the upper shell 240 and the lower cover 250 can be separated, and then the module bracket 120 and the injection module 206 can be connected.

[0048] The lower cover 250 is provided with a connection structure 251 and a guiding needle separation structure 252. After the implantation of the sensor device is completed, the lower cover 250 and the upper shell 240 can be assembled so that the connection structure 251 is fixed to the module bracket 120. In this state, when the lower cover 250 is separated from the upper shell 240 again, the connection structure 251 can drive the module bracket 120 to disengage from the injection module 206. In addition, when the lower cover 250 and the upper shell 240 are assembled, the guiding needle separation structure 252 can be used to drive the guiding needle 140 to loosen from the clamping module 211, so that the guiding needle 140 falls into the lower cover.

[0049] It can be seen that for the auxiliary implantation device 200 in this embodiment, after the sensor device is implanted, the lower cover 250 can be used to remove the module bracket 120 and the guiding needle 140 remaining on the injection module 206, so as to facilitate the assembly of a new sensor module and the injection module 206.

[0050] The following will describe the solution in this embodiment in detail in combination with the specific structures of the sensor module and the auxiliary implantation device.

[0051] Refer to Figure 2 and Figure 3, the sensor module 100 in the embodiments of the present application may further include a packaging box 110 and a desiccant 150. The module bracket 120, the sensor device 130, the guiding pin 140, and the desiccant 150 are all arranged in the packaging box 110. The packaging box 110 may include a bottom case 111 and a box cover 112. The bottom case 111 and the box cover 112 are detachably connected so that the box cover 112 can be closed on the bottom case 111, or the box cover 112 can be removed from the bottom case 111.

[0052] Reference Figure 4 , the module bracket 120 can be installed along the circumferential direction of the bottom case 111 on the inner wall of the bottom case 111. The inner wall of the bottom case 111 may be provided with a clamping structure 1111. The module bracket 120 can be relatively fixed to the inner wall of the bottom case 111 through the clamping structure 1111. When an external force acts on the clamping structure 1111, the module bracket 120 can also be separated from the clamping structure 1111, so as to facilitate the removal of the module bracket 120 from the bottom case 111.

[0053] Reference Figure 5 , the middle part of the module bracket 120 has an annular hole, which can be used to accommodate the sensor device 130. So that when the sensor device 130 is installed on the module bracket 120, the inner wall of the annular hole is in contact with the side wall of the sensor device 130, thereby playing a role in initially limiting the sensor device 130.

[0054] The inner wall of the annular hole may also be respectively provided with a positive buckle 121 and a negative buckle 122. Correspondingly, the sensor device 130 may be respectively provided with a positive card slot 1301 and a negative card slot 1302. When the sensor device 130 is placed in the annular hole, the positive buckle 121 can be clamped in the positive card slot 1301, and the negative buckle 122 can be clamped in the negative card slot 1302. At this time, under the joint action of the positive buckle 121 and the negative buckle 122, the sensor device 130 can be relatively fixed to the module bracket 120.

[0055] Specifically, the positive card slot 1301 of the sensor device 130 is arranged on the side of the sensor device 130, and a part of the positive card slot 1301 extends to the bottom of the sensor device 130. When the positive buckle 121 is clamped in the card slot, a part of the positive buckle 121 abuts against the bottom surface of the sensor device 130.

[0056] The negative card slot 1302 of the sensor device 130 is arranged on the side of the sensor device 130, and the opening of the negative card slot 1302 is opened on the side facing the top of the sensor device 130. When the negative buckle 122 is clamped in the negative card slot 1302, the negative buckle 122 can abut against the bottom of the negative card slot 1302.

[0057] Refer to together Figure 5and Figure 6 , when an acting force in the axial direction of the annular hole is applied to the sensor device 130, if the acting force acts on the top of the sensor device 130 (the arrow direction in Figure 5 can be referred to), it means pressing the sensor device 130 from top to bottom. At this time, the acting force acting on the sensor device 130 can be understood as the driving force for implanting the sensor device 130 into the user's skin, and this driving force is used to drive the sensor device 130 to move along the implanting direction. The positive buckle 121 can be an elastic structure. When the sensor device 130 is subjected to an acting force from top to bottom, this acting force can drive the sensor device 130 to move downward, causing the positive buckle 121 to disengage from the positive card slot 1301. During this process, the bottom of the negative card slot 1302 gradually moves away from the negative buckle 122. Therefore, the negative card slot 1302 and the negative buckle 122 will not affect the sensor device 130 to be disengaged from the module bracket 120.

[0058] On the contrary, when the sensor device 130 is pushed from bottom to top, the acting force acting on the sensor device 130 at this time can be understood as being used to drive the sensor device 130 to move in the reverse direction of the implanting direction. Since the negative buckle 122 abuts against the bottom of the negative card slot 1302, when this acting force is applied to the sensor device 130, under the buckling action of the negative card slot 1302 and the negative buckle 122, the sensor device 130 cannot move relative to the module bracket 120. That is, the negative card slot 1302 and the negative buckle 122 can be used to limit the sensor device 130 from being disengaged from the module bracket 120 in the reverse direction of its implanting direction.

[0059] Reference Figure 7 , the sensor device 130 can be provided with a through hole 1303 for passing through the guiding needle 140. The guiding needle 140 includes a plastic handle 141 and a needle body 142, and the needle body 142 can be located in the needle groove of the puncture needle after passing through the through hole 1303. When implanting the sensor device 130 into the user's skin, the guiding needle 140 can penetrate the skin prior to the puncture needle, so as to guide the puncture of the puncture needle.

[0060] Reference Figure 8 , in the embodiment of the present application, the injection module 206 can include an inner sleeve 220 and a return needle bracket 210, and the inner sleeve 220 is sleeved and connected to the return needle bracket 210. In addition, the auxiliary implanting device 200 in this embodiment can further include a main bracket 230 and a button module 260. The main bracket 230 is sleeved and connected to the inner sleeve 220, the upper shell 240 is sleeved and connected to the main bracket 230, and the button module 260 is arranged at the top of the upper shell 240.

[0061] When installing the sensor module 100 onto the inner sleeve 220, an engaging device can be provided between the inner sleeve 220 and the module bracket 120. When the engaging device is in the locked state, the inner sleeve 220 and the module bracket 120 are relatively fixed. When the engaging device is in the unlocked state, the inner sleeve 220 can be disengaged from the module bracket 120.

[0062] Reference Figure 10 , the engaging device can include a top rib 221 disposed on the inner wall of the inner sleeve 220 and a first bracket buckle 124 disposed on the module bracket 120. Among them, the top rib 221 is disposed near the bottom of the inner sleeve 220. When the engaging device is in the locked state, the first bracket buckle 124 abuts against the top rib 221. There are at least two top ribs 221 disposed on the inner sleeve 220. Correspondingly, there are also at least two first bracket buckles 124. When each top rib 221 abuts against the corresponding first bracket buckle 124 respectively, the inner sleeve 220 and the module bracket 120 can be kept relatively fixed.

[0063] Based on this, with reference to Figure 3 and Figure 10 , the module bracket 120 is further provided with a second buckle bracket 125. When the module bracket 120 is placed in the bottom case 111, the second bracket buckle 125 can abut against the engaging structure 1111, so as to realize the relative fixation between the module bracket 120 and the bottom case 111.

[0064] Reference Figure 9 , the clamping module 211 is disposed on the inner wall of the return needle bracket 210. The clamping module 211 has a clamping state and a non-clamping state. When the clamping module 211 is in the clamping state, the clamping module 211 can be used to clamp the guiding needle 140. When the clamping module 211 is in the non-clamping state, the guiding needle 140 can be released from the clamping module 211. Specifically, when the module bracket 120 installed with the sensor device 130 is relatively fixed to the inner sleeve 220, the clamping module 211 can clamp the plastic handle 141 of the guiding needle 140. When the sensor device 130 is not implanted into the user's skin, the clamping module 211 and the guiding needle 140 remain relatively fixed.

[0065] Reference Figure 10 and Figure 11 , a first limiting structure 202 is provided between the inner sleeve 220 and the main bracket 230. When the first limiting structure 202 is in the limiting state, the inner sleeve 220 and the main bracket 230 are relatively fixed. When the first limiting structure 202 is in the unlocked state, the inner sleeve 220 can move relative to the main bracket 230 along the axial direction of the inner sleeve 220.

[0066] The first limiting structure 202 may include a first sleeve buckle 2022 disposed on the inner wall of the inner sleeve 220 and a lapping portion 2021 disposed inside the main bracket 230. Among them, the first sleeve buckle 2022 protrudes from the inner wall surface of the inner sleeve 220, and the lapping portion 2021 is located in the middle of the main bracket 230. There is a certain gap between the lapping portion 2021 and the wall surface of the main bracket 230, and this gap can be used to pass through the side wall of the inner sleeve 220. That is to say, the inner sleeve 220 is sleeved on the lapping portion 2021, and the main bracket 230 is sleeved on the inner sleeve 220.

[0067] When the first limiting structure 202 is in the limiting state, that is, the first sleeve buckle 2022 abuts against the top surface of the lapping portion 2021. When the first limiting structure 202 is in the unlocking state, that is, the first sleeve buckle 2022 disengages from the lapping portion 2021. In addition, a main spring 270 is also connected between the inner sleeve 220 and the main bracket 230. When the first limiting structure 202 is in the limiting state, the main spring 270 is in a compressed state.

[0068] When the first limiting structure 202 switches to the unlocking state, the first sleeve buckle 2022 disengages from the lapping portion 2021. Due to the elastic potential energy of the main spring 270, the main spring 270 can drive the inner sleeve 220 to move downward relative to the main bracket 230.

[0069] It should be noted that the sensor module 100 and the auxiliary implanting device 200 in this embodiment are two independent structures. When it is necessary to implant the sensor device 130 into the human body, the packaging box 110 can be opened, and then the module bracket 120 can be connected to the inner sleeve 220, thereby realizing the reuse of the auxiliary implanting device 200.

[0070] On this basis, referring to Figure 12 and Figure 13 , a sleeve limiting rib 222 may also be provided at the bottom of the inner sleeve 220. Correspondingly, a limiting groove 126 may be provided on the module bracket 120. When assembling the bottom case 111 with the inner sleeve 220 from the bottom of the outer shell 240, the sleeve limiting rib 222 can be inserted into the limiting groove 126, so as to ensure the alignment between the top rib 221 and the first bracket buckle 124.

[0071] To facilitate the sleeve limiting rib 222 to accurately fit into the limiting groove 126, alignment lines may also be provided on the surface of the outer shell 240, and alignment lines may also be provided on the surface of the bottom case 111. When the two alignment lines are aligned, it means that the sleeve limiting rib 222 is exactly opposite to the limiting groove 126.

[0072] After the fixing of the module bracket 120 and the inner sleeve 220 is completed, the bottom case 111 can be pulled downwards to separate the module bracket 120 from the bottom case 111, thereby facilitating the subsequent implantation of the sensor device 130.

[0073] Reference Figure 14 , the button module 260 may include a button body 261 and a button spring 262. A button hole 242 may be provided at the top of the housing 240. The button body 261 may pass through the button hole 242. The button spring 262 may be connected between the button body 261 and the main bracket 230. Under an external force, the button body 261 may move relative to the housing 240 along the axial direction of the inner sleeve 220. During this process, the button body 261 may compress the button spring 262. When the external force disappears, the button spring 262 may drive the button body 261 to return to the initial position.

[0074] Combined with Figure 10 and Figure 14 , when the first limiting structure 202 is in the limiting state, the first sleeve buckle 2022 abuts against the top surface of the overlapping portion 2021. At this time, when the button body 261 is pressed downwards, the bottom of the button body 261 may contact the top of the first inner cylinder buckle. During the continuous pressing down of the button body 261, the button body 261 may squeeze the first sleeve buckle 2022, causing the first sleeve buckle 2022 to disengage from the top surface of the overlapping portion 2021, thereby completing the switching of the first limiting structure 202 from the limiting state to the unlocking state.

[0075] A first guiding surface may be provided at the bottom of the button body 261. The first guiding surface is an inclined surface. A second guiding surface may be provided at the top of the first sleeve buckle 2022. The second guiding surface is also an inclined surface. Moreover, the first guiding surface and the second guiding surface are arranged in parallel. When the button body 261 contacts the first sleeve buckle 2022, the first guiding surface contacts the second guiding surface. During the further downward movement of the button body 261, the first guiding surface may generate a force that extrudes the first sleeve buckle 2022 outwards, causing the first sleeve buckle 2022 that was originally facing the overlapping portion 2021 to be squeezed into a state misaligned with the overlapping portion 2021, so as to facilitate the movement of the first sleeve buckle 2022 to the gap between the overlapping portion 2021 and the inner wall of the main bracket 230.

[0076] It should be noted that in the initial state of the auxiliary implantation device 200 in this embodiment, the first limiting structure 202 is in the unlocking state, the inner sleeve 220 and the main bracket 230 are in a relatively movable state, and the first sleeve buckle 2022 of the inner sleeve 220 is located below the overlapping portion 2021.

[0077] Reference Figure 15, a second limiting structure 201 may be provided between the return needle bracket 210 and the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the return needle bracket 210 and the inner sleeve 220 are relatively fixed. When the second limiting structure 201 is in the unlocked state, the return needle bracket 210 can move relative to the inner sleeve 220 along the axial direction of the inner sleeve 220.

[0078] Specifically, the second limiting structure 201 may include a return needle buckle 2012 provided on the outer wall of the return needle bracket 210 and a second sleeve buckle 2011 provided on the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the return needle buckle 2012 abuts against the bottom of the second sleeve buckle 2011, so that the return needle bracket 210 and the inner sleeve 220 are relatively fixed.

[0079] A return needle spring 280 may also be connected between the return needle bracket 210 and the inner sleeve 220. When the second limiting structure 201 is in the limiting state, the return needle spring 280 is in a compressed state. When the second limiting structure 201 is switched to the unlocked state, due to the elastic potential energy of the return needle spring 280, it can drive the return needle bracket 210 to move upward relative to the inner sleeve 220.

[0080] Refer to Figure 9 and Figure 15 , a third limiting structure is further provided on the inner wall of the main bracket 230. The third limiting structure may be provided at a position close to the bottom of the main bracket 230. As described above, the inner sleeve 220 can move downward relative to the main bracket 230. The third limiting structure can be used to limit the moving distance of the inner sleeve 220 relative to the main bracket 230, preventing the main spring 270 from undergoing plastic deformation due to excessive moving distance of the inner sleeve 220.

[0081] The third limiting structure may include a bracket hook 232 provided on the inner wall of the main bracket 230. The number of the bracket hooks 232 may be the same as the number of the second sleeve buckles 2011, and they are arranged in one-to-one correspondence. When the inner sleeve 220 moves relative to the main bracket 230, the second limiting structure 201 is in the limiting state, that is, the inner sleeve 220 and the return needle bracket 210 are relatively fixed, and the inner sleeve 220 drives the return needle bracket 210 to move downward together. Since the return needle buckle 2012 abuts against the bottom of the second sleeve buckle 2011, when the bracket hook 232 and the inner sleeve 220 play a limiting role, the return needle buckle 2012 is clamped between the bracket hook 232 and the second sleeve buckle 2011. At this time, if the inner sleeve 220 continues to move downward, the bracket hook 232 and the second sleeve buckle 2011 can cooperate to squeeze the return needle buckle 2012, so that the return needle buckle 2012 is separated from the contact with the second sleeve buckle 2011, and then the bracket hook 232 abuts against the bottom of the second sleeve, so as to make the main bracket 230 and the inner sleeve 220 relatively fixed.

[0082] It can be understood that the bracket buckle in this embodiment can not only be used to limit the moving distance of the inner sleeve 220, but also be used to drive the second limiting structure 201 to switch from the limiting state to the unlocking state. Moreover, in the process of the inner sleeve 220 continuously moving downward relative to the main bracket 230, it is the process of implanting the sensor device 130 into the user's skin. When the bracket hook 232 abuts against the second sleeve buckle 2011, it means that the sensor device 130 is implanted in place.

[0083] A third guiding surface may be provided at the bottom of the return needle buckle 2012, and a fourth guiding surface may be provided at the top of the bracket hook 232. Both the third guiding surface and the fourth guiding surface are inclined in the axial direction of the inner sleeve 220. Moreover, the third guiding surface is parallel to the fourth guiding surface. When the return needle buckle 2012 contacts the bracket hook 232, the third guiding surface fits with the fourth guiding surface. Under the extrusion of the second sleeve buckle 2011, the third guiding surface can slide along the fourth guiding surface, so that the return needle buckle 2012 can be more easily separated from the second sleeve buckle 2011.

[0084] Reference Figure 16 , since the return needle bracket 210 is provided with a clamping module 211 for clamping the guiding needle 140, after the sensor device 130 is implanted into the user's skin, due to the second limiting structure 201 being in the unlocking state, the elastic potential energy of the return needle spring 280 can drive the return needle bracket 210 to move upward relative to the inner sleeve 220. During this process, the return needle bracket 210 can drive the guiding needle 140 to move upward, so that the guiding needle 140 is separated from the sensor device 130.

[0085] Refer to together Figure 1 and Figure 17 , the connection structure 251 in the lower cover 250 may include a first buckle 2511 provided on the bottom wall of the lower cover 250. Correspondingly, the module bracket 120 is provided with an abutting buckle 127. When the lower cover 250 is assembled with the upper shell 240, the abutting buckle 127 is located at the bottom of the first buckle 2511, and the first buckle 2511 abuts against the abutting buckle 127. At this time, the module bracket 120 and the lower cover 250 remain relatively fixed. When the lower cover 250 is separated from the upper shell 240 again, since the first buckle 2511 is located above the abutting buckle 127, during the process of pulling down the lower cover 250, the first buckle 2511 can squeeze the abutting buckle 127 downward, so that the first bracket buckle 124 and the top rib 221 can be separated. Thus, the module bracket 120 can move away from the inner sleeve together with the lower cover 250.

[0086] In this embodiment, a plurality of abutting buckles 127 may be provided, and the plurality of abutting buckles 127 may be distributed at intervals along the circumferential direction of the module bracket 120. Correspondingly, there are also a plurality of first buckles 2511, and the plurality of first buckles 2511 are provided in one-to-one correspondence with the plurality of abutting buckles 127. When the lower cover 250 is assembled with the upper shell 240, each first buckle 2511 abuts against the corresponding abutting buckle 127 respectively. When the lower cover 250 is pulled down, the extrusion effect of the lower cover 250 on the module bracket 120 can be increased, so as to ensure the separation of the module bracket 120 from the inner sleeve 220.

[0087] Based on this, a positioning structure may also be provided between the lower cover 250 and the upper shell 240. When the lower cover 250 and the upper shell 240 are assembled, the lower cover 250 and the upper shell 240 can be positioned through the positioning structure, so that each first buckle 2511 can be aligned with the abutting buckle 127.

[0088] Exemplarily, the positioning structure may include an alignment line provided on the outer surface of the upper shell 240 and an alignment line provided on the outer surface of the lower cover 250. When the lower cover 250 is assembled with the upper shell 240, the two alignment lines can be aligned, so as to complete the alignment and positioning between the lower cover 250 and the upper shell 240.

[0089] Reference Figure 17 , the clamping module 211 may include two clamping rods 2111, and the two clamping rods 2111 are arranged on the inner wall of the return needle bracket 210. Moreover, the clamping rods 2111 are arranged obliquely to the axis direction of the return needle bracket 210. The ends of the two clamping rods 2111 are close to each other, so as to cooperate to clamp the guiding needle 140.

[0090] When the module bracket 120 is relatively fixed to the inner sleeve 220 through the clamping device, since the plastic handle 141 of the guiding needle 140 protrudes from the module bracket 120 and extends towards the key module 260. During the process of fixing the module bracket 120 and the inner sleeve 220, the guiding needle 140 can squeeze the two clamping rods 2111 from bottom to top, so that the ends of the two clamping rods 2111 are far away from each other, so that the plastic handle 141 of the guiding needle 140 can pass through between the ends of the two clamping rods 2111 and be clamped by the cooperation of the ends of the two clamping rods 2111.

[0091] Refer to again Figure 17, the guide pin separation structure 252 inside the lower cover 250 may include two return pin ejector rods 2521 disposed on the bottom wall of the lower cover 250. The return pin ejector rods 2521 extend along the axial direction of the lower cover 250 to protrude from the upper surface of the lower cover 250. The two return pin ejector rods 2521 are arranged in one-to-one correspondence with the two clamping rods 2111. When the lower cover 250 is assembled with the upper shell 240, the two return pin ejector rods 2521 respectively apply extrusion forces to the two clamping rods 2111, whereby the ends of the two clamping rods 2111 can be moved away from each other, so that the guide pin 140 can fall off between the two clamping rods 2111 and fall into the lower cover 250.

[0092] The two return pin ejector rods 2521 may be spaced apart. When the guide pin 140 becomes loose from the two clamping rods 2111, the guide pin 140 can fall into the space between the two return pin ejector rods 2521. In addition, the guide pin separation structure 252 may further include a magnetic attraction structure 2522 disposed between the two return pin ejector rods 2521. The magnetic attraction structure 2522 can have an adsorption effect on the guide pin 140, so that the guide pin 140 can fall more precisely between the two return pin ejector rods 2521.

[0093] Continue to refer to Figure 17 , a groove 2112 may be provided at the bottom of the clamping rod 2111. The groove 2112 may be a V-shaped groove, and the opening of the groove 2112 faces the side of the lower cover 250. A protrusion 2523 may be provided at the top of the return pin ejector rod 2521. When the lower cover 250 is assembled with the upper shell 240, at least a part of the protrusion 2523 can be engaged in the groove 2112 and squeeze the clamping rod 2111 with this, so that the ends of the two clamping rods 2111 move away from each other.

[0094] In addition, a second buckle 253 may be provided on the inner wall of the lower cover 250. Since the upper shell 240 is sleeved and connected to the main bracket 230, an annular slot may be provided on the outer wall of the main bracket 230. When the lower cover 250 is assembled with the upper shell 240, the second buckle 253 on the inner wall of the lower cover 250 can be engaged in the annular slot, so that the lower cover 250 and the main bracket 230 are kept relatively fixed, that is, the lower cover 250 and the upper shell 240 can be kept relatively fixed.

[0095] Combined with the above embodiments, after the implantation of the sensor device 130 is completed, when the auxiliary implantation device 200 is removed upward, the positive buckle 121 is disengaged from the positive slot 1301, so that the module bracket 120 is separated from the sensor device 130. The sensor device 130 remains in the human body, and the module bracket 120 remains on the inner sleeve 220.

[0096] Next, the lower cover 250 of the auxiliary implant device 200 is installed on the upper shell 240 again, and the first buckle 2511 on the lower cover 250 is engaged with the abutting buckle 127 of the module bracket 120. At the same time, the return pin ejector rod 2521 pushes open the two clamping rods 2111, causing the guiding needle 240 to fall into the lower cover. Subsequently, the lower cover 250 is removed, and the lower cover 250 can take away the module bracket 120 and the guiding needle 240 together.

[0097] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
