Problems solved by technology

Therefore, when the screwdriver is inserted from the incision, a large extrusion force will be formed between the screwdriver and the end of the screw on part of the sealing plug body, thereby causing the part of the sealing plug body to be squeezed and damaged, making it difficult to restore the original shape

Abstract

The invention relates to a sealing plug. The sealing plug which is applied to an implantable medical device comprises a plug body which is made of an insulating elastic material. A groove is arranged at the top of the plug body. A hole is arranged in the bottom of the plug body. A slit which communicates the groove and the hole is arranged in the plug body. Through the slit, a screwdriver passes through the plug body. A screw is partially accommodated in the hole. The hole comprises a first hole and a second hole, wherein the first hole and the second hole are orderly arranged from the inside out and are communicated. The diameter of the first hole is smaller than the diameter of the second hole. The invention further relates to the implantable medical device using the sealing plug.

Description

technical field [0001] The invention belongs to the field of micro medical instruments, in particular to a sealing plug and an implantable medical device using the sealing plug. Background technique [0002] At present, implantable medical devices are widely used in the treatment of diseases such as nervous system and cardiac system. Implantable medical devices include deep brain stimulation, implanted cerebral cortex stimulation, implanted spinal cord electrical stimulation, implanted sacral nerve electrical stimulation, implanted vagus nerve electrical stimulation, implanted cardiac electrical stimulation system (commonly known as cardiac pacemaker), implanted drug infusion system, etc. [0003] After these implantable medical devices are implanted into the human body, they need to operate safely and stably, which requires ensuring the sealing of each connection part to prevent the infiltration of body fluid from affecting the circuit transmission. When the implantable m...
