Instrument for transforaminal endoscopic fusion surgery and using method of instrument

Abstract

The invention relates to an instrument for transforaminal endoscopic fusion surgery and a using method of the instrument, and relates to the field of medical instruments. The instrument for the transforaminal endoscopic fusion surgery comprises an operating rod and a tool bit fixedly connected to one end of the operating rod and used for treating an intervertebral disc; and the operating rod is ina hollow cylinder shape, and an transforaminal endoscope can extend into the operating rod so as to observe the degree of the tool bit for treating the intervertebral disc. The instrument has the effects that the sight of a doctor is not blocked in an operation, meanwhile, the operation efficiency can be improved, and the operation time is shortened.

Description

technical field [0001] The present application relates to the field of medical instruments, in particular to an instrument for transforaminal endoscopic fusion surgery and a method of use thereof. Background technique [0002] At present, with the aging of the social population, the degenerative diseases of the spine are on the rise year by year, and severe intervertebral disc herniation and other symptoms often require surgery such as intervertebral fusion. During surgical treatment, the doctor will first need to make instruments enter the intervertebral space, deal with herniated and prolapsed intervertebral discs, clean up diseased intervertebral discs, and establish a space for fusion cages. Traditional transforaminal endoscopic fusion surgery uses various instruments. Various, such as reamers, curettes, bone bruises, rongeurs, etc., according to the need to choose the appropriate equipment to use, and when using each equipment is a blind operation, and it is easy to dam...

Problems solved by technology

During surgical treatment, the doctor will first need to make instruments enter the intervertebral space, deal with herniated and prolapsed intervertebral discs, clean up diseased intervertebral discs, and establish a space for fusion cages. Traditional transforaminal endoscopic fusion surgery uses various instruments. Various, such as reamers, curettes, bone bruises, rongeurs, etc., according to the need to choose the appropriate equipment to use, and when using each equipment is a blind operation, and it is easy to damage the nerves, dura mater

[0003] At present, with the promotion of minimally invasive transforaminal endoscopic surgery, it is generally necessary to insert the instrument for transforaminal endoscopic fusion surgery into the cannula of the intervertebral foramina endoscope during the operation. This form makes the instrument The diameter of the stem is limited, the size of surgical instruments is also limited, the speed of discectomy is also slow, and the efficiency of handling the intervertebral disc during the operation is not high, which greatly increases the operating time of the doctor, leads to the fatigue of the doctor, and increases the risk index of the operation.
