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.

Embodiment Construction

[0045] The following is attached Figure 1-10 The application is described in further detail.

[0046] The embodiment of the present application discloses an instrument for transforaminal endoscopic fusion surgery. refer to figure 1 , the instrument for transforaminal endoscopic fusion surgery includes an opener for cutting the annulus fibrosus, a rotary scraper for shredding the nucleus pulposus and taking it out of the human body, and a lower terminal end for the upper vertebral body. The lifting scraper is used to scrape the upper endplate of the lower vertebral body and the upper endplate of the lower vertebral body, and the advancing scraper is used to process the residual intervertebral disc. Next, the opener, rotating scraper, lifting scraper and push scraper will be introduced in turn.

[0047] refer to figure 2 The gag includes a first operating rod 11 and a cutter 12 fixed at one end of the first operating rod 11 for cutting the annulus fibrosus. Specifically, ...

Abstract

The application relates to an instrument for transforaminal endoscopic fusion surgery and its use method, and relates to the field of medical instruments. The instrument for transforaminal endoscopic fusion surgery includes an operating rod and one end of the operating rod is fixed for The cutter head for processing the intervertebral disc, the operating rod is a hollow cylinder inside which can be inserted into the hole mirror to observe the degree of processing the intervertebral disc by the cutter head. The present application has the effect of not blocking the doctor's line of sight during the operation, but also improving the operation efficiency and shortening the operation time.

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...
