Description

Implantation tool and method for assembling the same Technical Field The invention relates to the technical field of medical auxiliary instruments, in particular to an implantation tool and an assembly method of the implantation tool. Background The dynamic blood glucose monitoring system CGM is a system for monitoring the blood glucose index of a human body, and the dynamic blood glucose monitoring system CGM in the prior art is characterized in that a blood glucose sensor is implanted subcutaneously, enzyme on the sensor reacts with subcutaneous tissue fluid to detect the blood glucose value, and the blood glucose value is sent to a terminal by matching with a transmitter, so that the continuous blood glucose value can be acquired. For the dynamic blood glucose monitoring system CGM, the implantation tool for implanting the blood glucose sensor is one of the indispensable devices, and the blood glucose sensor and the transmitter can be simply and quickly implanted on a human body through the implantation tool. The implantation tool in the prior art comprises a shell, a pushing and shooting piece, a driving key, a transmitter and a sensor, wherein the pushing and shooting piece is buckled on the shell, the driving key is arranged on the shell and used for driving the pushing and shooting piece to trip, the transmitter is detachably arranged at one end of the shell, and the sensor is buckled on the pushing and shooting piece. In the implantation tool in the prior art, only the shell, the injection piece, the driving key and the sensor are arranged together in the production process, and the transmitter and the shell are separately arranged when leaving the factory. When the implantation tool is used, a user needs to manually detachably arrange the transmitter at one end of the shell, then the pushing piece is triggered to release by pressing the driving key, and the released pushing piece sends the sensor into the transmitter. After the sensor is sent into the emitter, the sensor is buckled on the emitter, and meanwhile, the sensor and the pushing and shooting piece are tripped, so that the use of the implantation tool is completed. However, by means of such a connection structure, a large number of mating structures are required between the ejector and the sensor, between the emitter and the housing, and between the emitter and the sensor, resulting in a complex internal structure of the implantation tool. Disclosure of Invention In the implantation tool aiming at the prior art, the emitter and the shell are separately arranged, and the emitter is detachably arranged at one end of the shell when in use, so that a large number of snap fit structures are required to be arranged in the implantation tool, and the structure of the implantation tool is complex. And during the use of the implantation tool, the user may also misload the emitter. The invention provides an implantation tool, which is characterized in that an emitter is detachably arranged on a pushing and shooting piece, and a sensor is arranged on the emitter, so that a matching structure which is needed to be arranged between the sensor and the emitter, between the sensor and the pushing and shooting piece and between the emitter and a shell can be omitted, and the implantation tool is simpler. Simultaneously, the implantation tool can be assembled with the integral structure when leaving the factory, and when the implantation tool is used by a user, the use of the implantation tool can be completed only by pressing the driving key, so that the problem that the transmitter is wrongly assembled by the user can be effectively avoided, the operation of the implantation tool is simpler, and the use experience of the user is effectively improved.
