Please refer to fig. 1 to 6 in combination. The present embodiment provides an implant tool 100 comprising a housing 10, a pusher 20, a drive key 30, a transmitter 40, a sensor 50, an implant needle assembly 60. The housing 10 is provided with an accommodating space 12 having an opening 11 at one end, and the ejector 20 is accommodated in the accommodating space 12 and is locked to the housing 10. It should be noted that "snap-in" in this embodiment means that one component is connected to another component by a corresponding snap-in structure, and the two components can be separated from each other in a corresponding state. The driving key 30 is disposed on the housing 10, and the driving key 30 is used for driving the ejector 20 to release from the housing 10. That is, the state of the ejector 20 is changed by the driving key 30, and the ejector 20 can be changed from the "locked" state to the "unlocked" state by the driving key 30, so that the ejector 20 is separated from the housing 10.

The emitter 40 is detachably disposed on the ejector 20, and the sensor 50 is disposed on the emitter 40. The specific structure of the ejector 40 detachably disposed on the ejector 20 may be any desired structure, such as a clamping connection, a threaded connection, etc., only when the ejector 20 is in a clamping state, the ejector 40 can be stably fixed with the ejector 20, so that the ejector 20 can correspondingly drive the ejector 40 to move after being tripped; meanwhile, when the ejector 20 moves in place, the ejector 40 can be separated from the ejector 20.

The implantation needle assembly 60 is snapped onto the injector 20 and passes through the sensor 50. The needle tip of the implant needle assembly 60 extends beyond the sensor 50 toward the opening 11. Therefore, when in use, after the user releases the ejector 20 by pressing the driving button 30, the ejector 20 drives the emitter 40 and the implantation needle assembly 60 to move synchronously, and when the ejector moves to a certain distance, the needle head of the implantation needle assembly 60 will first penetrate into the human body, so that the sensor 50 can correspondingly contact with the blood of the human body, and finally the emitter 40 is separated from the housing 10, and the emitter 40 is left on the human body, thus completing the use of the implantation tool 100 once.

It will be appreciated that in prior art implant tools, the emitter and housing are separately located and the sensor is snapped onto the injector. When the implantation tool is used, a user needs to manually detachably arrange the transmitter at one end of the shell, then the pushing and shooting piece is tripped by pressing the driving key, and the tripped pushing and shooting piece sends the sensor into the transmitter. In order to ensure smooth butt joint between the sensor and the emitter, a buckle matching structure is arranged between the sensor and the pushing and shooting piece, when the pushing and shooting piece is not tripped and the pushing and shooting piece drives the sensor to move, the sensor is fixed by the buckle structure on the pushing and shooting piece, and when the sensor is sent into the emitter, the buckle structure on the pushing and shooting piece needs to be separated from the sensor; and meanwhile, a snap fit structure is also arranged between the sensor and the transmitter, and after the sensor is sent into the transmitter, the sensor is fixed by the snap fit structure on the transmitter, so that the connection and fixation between the final sensor and the transmitter are ensured. And corresponding matching structures are required to be arranged between the shell and the emitter so as to ensure that the emitter can be successfully connected with the sensor. Therefore, a large number of structures and parts are required to be arranged in the implantation tool in the prior art, so that the internal structure of the implantation tool is complex, the manufacturing and processing difficulty is increased, meanwhile, the requirement on the accuracy of the installation position of each part is higher due to the multiple matching structures, and the use stability of the implantation tool is easily influenced.

In the implantation tool 100 according to the present embodiment, the emitter 40 is directly detachably disposed on the injector 20, and the sensor 50 is directly disposed on the emitter 40. Therefore, no corresponding snap-fit structure is required to be arranged between the sensor 50 and the emitter 40 and between the sensor 50 and the ejector 20, and no corresponding fit structure is required to be arranged between the shell 10 and the emitter 40, so that the whole structure is simpler, the design is simplified, the structure and the number of parts are reduced, the processing and manufacturing difficulty is reduced, the requirement on the precision of the mounting position can be reduced, and the stability of the implantation tool 100 in the use process is better ensured. Meanwhile, the implantation tool 100 may be assembled to complete the whole structure at the time of shipment, i.e., the transmitter 40 and the sensor 50 are assembled during the manufacturing process. When the implantation tool 100 is used, a user can use the implantation tool 100 only by pressing the driving key 30, so that the problem that the user misloads the transmitter can be effectively avoided, and meanwhile, the operation of the implantation tool 100 is simpler, and the use experience of the user is effectively improved.

Meanwhile, it will be appreciated that the emitter in the prior art needs to be mounted on the housing, so that the emitter is usually required to be relatively large in size, so that the emitter can be normally mounted on the housing. After the implantation tool is used, the emitter and the sensor are required to be placed on the human body, and the emitter with a larger volume is placed on the human body, so that the use experience of a user can be affected. In the implantation tool 100 provided in this embodiment, the emitter 40 is detachably disposed on the ejector 20, so that the emitter 40 does not need to be matched with the housing 10, so that the volume of the emitter 40 can be smaller, the volume of the emitter 40 can be reduced, and the use experience of a user can be better improved. Specifically, in this embodiment, the volume of the emitter 40 may be phi 22.9×3.5mm.

Preferably, the implantation tool 100 further comprises a sleeve 70, the sleeve 70 being detachably connected to the sensor 50. The portion of the implant needle assembly 60 extending beyond the sensor 50 is positioned within the cannula 70 toward the opening 11. The sleeve 70 can well protect the sensor 50 and the implantation needle assembly 60 from damage after the sensor 50 and the implantation needle assembly 60 are produced and assembled. At the same time, the sleeve 70 can well isolate the outside air and humidity, and better protect the sensor 50 and the implantation needle assembly 60.

Preferably, the implantation tool 100 further comprises a shoe 80, wherein the shoe 80 is screwed with the housing 10 and closes the opening 11. The sleeve 70 is screwed with the sensor 50, and the sleeve 70 is connected with the shoe 80, i.e. in this embodiment, the detachable specific connection mode between the sleeve 70 and the sensor 50 is a screw connection. The threads between the shoe 80 and the housing 10, and between the sleeve 70 and the sensor 50, are the same in direction. I.e. when left-handed threads are provided between the shoe 80 and the housing 10, left-handed threads are provided between the sleeve 70 and the sensor 50; when right-hand threads are provided between the shoe 80 and the housing 10, right-hand threads are provided between the sleeve 70 and the sensor 50. Since the shoe 80 is coupled to the sleeve 70, the shoe 80 simultaneously rotates the sleeve 70 when the user screws the shoe 80. So that the user can remove the sleeve 70 from the sensor 50 at the same time when removing the shoe 80 from the housing 10. The inside of the housing 10 can be better sealed by the shoe 80, so that the waterproof and dustproof properties of the implantation tool 100 are ensured, and the sleeve 70 is also convenient to disassemble.

Preferably, the outer surface of the sleeve 70 is provided with a first connection portion 71, the inside of the shoe 80 is provided with a second connection portion 81 matching with the first connection portion 71, and the first connection portion 71 and the second connection portion 81 are mutually embedded. Thus, the connection reliability between the shoe 80 and the sleeve 70 can be better ensured by the structure, and the user can synchronously detach the sleeve 70 when screwing and detaching the shoe 80. Specifically, in this embodiment, the first connection portion 71 is a groove formed on the outer surface of the sleeve 70, and the second connection portion 81 is a protrusion formed inside the bottom support 80, and the protrusion is correspondingly embedded in the groove. Of course, in other embodiments, the first connection portion 71 may be a protrusion formed on the outer surface of the sleeve 70, and the second connection portion 81 may be a groove formed inside the bottom bracket 80. More preferably, the plurality of first connecting portions 71 on the outer surface of the sleeve 70 are provided, all the first connecting portions 71 are distributed on the outer surface of the sleeve 70 at equal intervals along the circumferential direction of the sleeve 70, and each of the first connecting portions 71 is correspondingly embedded with one second connecting portion 81, so that the connection reliability between the bottom support 80 and the sleeve 70 can be better ensured.

Preferably, the housing 10 includes a shell 13 and a hook assembly 14, and the hook assembly 14 includes a hook 141 and an elastic member 142. Wherein the elastic member 142 refers to: elastic deformation can be generated after stress, and the original state of the component can be restored after the stress is relieved or eliminated. The hook 141 is connected to the housing 13 through the elastic member 142, and the injection member 20 is fastened to the hook 141. The driving button 30 is abutted against the hook 141 to press the elastic member 142, so that the ejector 20 is locked to the hook 141; and an unlocking state in which the elastic member 142 is extended and the ejector 20 is separated from the hook 141 by being separated from the hook 141. Specifically, in this embodiment, the elastic member 142 is a spring, and the elastic member 142 is disposed along a radial extension of the housing 13. When the driving key 30 is in a locking state, the driving key 30 abuts against the back of the hook 141, so as to prevent the hook 141 from moving towards the center, at this time, the elastic member 142 is in a compressed state, and the injection member 20 is buckled and hung on the hook 141; after the user presses the driving button 30, the driving button 30 is separated from the hook 141 after sinking to a certain position, the driving button 30 is in an unlocked state, and the elastic member 142 stretches to drive the hook 141 to move toward the center due to the back of the hook 141 losing the supporting force, and when the hook 141 moves to a certain distance, the hook 141 is separated from the ejector 20, thereby releasing the ejector 20. The trip of the ejector 20 is realized by utilizing the downward stroke conversion of the driving key 30 to the transverse movement of the hook 141, so that the driving key 30 is triggered more lightly and sensitively, and the use experience of a user is better promoted.

Preferably, the driving key 30 includes a key body 31 and a stopper 32, the key body 31 is movably disposed on the housing 13, the stopper 32 is connected with the key body 31, and the stopper 32 is used for abutting against and separating from the hook 141. That is, in this embodiment, the driving key 30 specifically includes two parts, and the stop block 32 is used to abut against and limit the hook 141, so that the user presses the key body 31 to drive the stop block 32 to sink during operation, thereby facilitating the user operation, and simultaneously, better ensuring that the driving key 30 abuts against and limits the hook 141.

Preferably, at least two hook assemblies 14 are provided, and the hook assemblies 14 are disposed at intervals between two pairs along the radial direction of the housing 13. The stop 32 is positioned intermediate each of the hanger assemblies 14 to abut each of the hangers 141. Therefore, through the structure, the stress of the pushing and injecting member 20 can be balanced better, the lateral deviation of the pushing and injecting member 20 is avoided, and the stability of the pushing and injecting member 20 in the pushing and injecting process can be guaranteed. Specifically, in the present embodiment, only two hook assemblies 14 are provided for illustration, and of course, in other embodiments, the number of hook assemblies 14 may be changed according to the actual requirement.

Preferably, the implantation tool 100 further includes a key protection cover 90, and the key protection cover 90 is movably disposed on the housing 10 to shield the driving key 30. Therefore, the user can be better prevented from touching the driving key 30 by mistake through the key protection cover 90, and the safety is better ensured. Specifically, in this embodiment, the key protection cover 90 has a flip-type structure, and when in use, the driving key 30 is exposed by flipping the key protection cover 90.

The working principle of the implantation tool 100: when in use, the shoe 80 is screwed first, the shoe 80 and the sleeve 70 are disassembled, then the key protection cover 90 is opened, and the driving key 30 is pressed to enable the stop block 32 to sink; when the stop block 32 is sunk to a certain position and then separated from the hook 141, the hook 141 is retracted to the center under the action of the elastic piece 142, and the hook 141 is separated from the ejector 20 and tripped after being retracted for a certain distance; after the ejector 20 is tripped, the driving spring on the ejector 20 drives the ejector 20 to move downwards, so that the emitter 40 and the implantation needle assembly 60 arranged on the ejector 20 move downwards synchronously; after the ejector 20 moves down to a certain position, the needle head on the implantation needle assembly 60 firstly pierces the human body, and meanwhile, the ejector 20 drives the emitter 40 to move down continuously until after moving to a certain position, the pin on the ejector 20 can travel to the end surface of the slide rail of the housing 13 to stop pushing down, and at this time, the emitter 40 can be implanted into the human body together with the sensor 50; after the implantation needle assembly 60 pierces the human body, the needle withdrawing spring on the implantation needle assembly 60 also drives the needle head of the implantation needle assembly 60 to withdraw upwards to withdraw the needle.

The implantation tool 100 provided in this embodiment has a simple structure, simplifies the design, and reduces the number of structures and parts. The sensor 50 and the transmitter 40 are installed at the time of shipment, and a user can use the sensor by unscrewing the shoe 80. While also enabling individual sterilization of the sensor 50 by the provision of the sleeve 70, a sterilization volume is reduced. And the size of the emitter 40 can be reduced, so that the use experience of a user is improved.

The embodiment also provides an assembly method of the implantation tool, which comprises the following steps:

s1, sterilizing the sensor 50;

s2, mounting the sterilized sensor 50 on the emitter 40;

s3, assembling the emitter 40 with the sensor 50, the shell 10, the ejector 40, the driving key 30 and the implantation needle assembly 60 together to form the implantation tool 100.

It will be appreciated that since the sensor needs to be brought into the human body during subsequent operations, gamma sterilization of the sensor is required during production. In the prior art, when the implantation tool is assembled, the sensor is firstly arranged on the injection pushing piece, the implantation tool is assembled into a whole, and then the implantation tool is sterilized integrally. This not only increases the overall sterilization costs, but also necessitates the selection of gamma resistant materials for the implant tool material or the additional provision of gamma resistant structures.

In the method for assembling the implantation tool provided in this embodiment, the sensor 50 is sterilized separately, so that the volume of the whole sterilization can be reduced, the cost is reduced, other structures in the implantation tool can be selected as required, and no additional gamma-resistant structure is required in the implantation tool.

Preferably, the method further comprises the following steps before step S1:

please refer to fig. 7 in combination. S0, the implantation needle in the implantation needle assembly 60 is mounted on the sensor 50, and then the sensor 50 is mounted in the receiving cavity 210 of the sensor protection mechanism 200. The sensor protection mechanism 200 includes a sleeve 70 and a protection cover 220, wherein the protection cover 220 is detachably connected with the sleeve 70 and encloses a closed accommodating cavity 210.

It will be appreciated that the sensor 50 can be effectively protected by the sensor protection mechanism 200, such that the sensor 50 can be gamma sterilized during sterilization alone, without the need for integral sterilization after assembly of the sensor 50 to an implantation tool. And with this construction the overall sensor 50 size can be reduced, providing the prior art for the overall size selection of the subsequent emitter 40. And the sensor protection mechanism 200 can realize free grabbing in the production process, so that the implantation needle and the sensor 50 are effectively protected, and damage caused by collision of the implantation needle and the sensor 50 in the production process is avoided.

Specifically, in this embodiment, the sensor 50 is threadably coupled to the sleeve 70.

Preferably, step S1 specifically includes:

s1, performing independent gamma sterilization on the sensor 50 and the implantation needle which are arranged in the protection mechanism 200;

the step S2 specifically comprises the following steps:

please refer to fig. 8 in combination. S2, the protective cover 220 is detached from the sleeve 70, and the part of the sensor 50 exposed out of the sleeve 70 is installed in the groove of the transmitter 40.

Specifically, before the sensor 50 is installed, a layer of glue is brushed on the surface of the groove of the emitter 40 by using UV waterproof glue, and when the sealing end surface of the sensor assembly 50 is attached to the glue sealing end surface of the emitter 40 for curing, a sealing layer is formed. Thus, the sterilization requirements of the sensor 50 and the requirements of the IPX8 waterproof grade can be simultaneously met in this way.

The sensor 50 provided in this embodiment is provided with a threaded structure, so that the sensor 50 can be in threaded connection with an external structure, and the sensor assembly 50 can be conveniently mounted and abutted with other structures. When the sensor 50 is sterilized, the sensor 50 is not required to be installed in an implantation tool for integral sterilization, but the sensor 50 can be independently installed on other thread structures for independent sterilization, so that the sterilization cost can be effectively reduced. Meanwhile, the detachable connection of the sensor 50 can be realized in a threaded connection mode, and the normal use of the sensor 50 is not affected.

While the invention has been described with respect to the above embodiments, it should be noted that modifications can be made by those skilled in the art without departing from the inventive concept, and these are all within the scope of the invention.
