Developing assembly, implantation instrument and manufacturing method of implantation instrument

A developing assembly, an implant instrument and a method of making the implant instrument, the developing assembly including a developing element and an extension, the developing element shuttling through a degradable implant, and a distal end of the developing element being connected to a distal end of the degradable implant. One end of the extension part is connected to the near end of the developing element, penetrates out of the degradable implant and is suitable for driving the far end of the developing element to be separated from the far end of the degradable implant, so that the developing element is driven to be separated from the degradable implant. In the application, by arranging the developing assembly, the degradable implant can be observed through medical images such as X-rays and TEE, so that an operator can accurately judge the position, the state and the like of the degradable implant, and the implantation effect is ensured. And after implantation is completed, the developing element can be
