Spacer device for fixing band between spinous processes

Abstract

The present invention relates to a spacer device for fixing a band between spinous processes, the spacer device comprising: a band unit which has a certain degree of tension and is disposed between aspinous process and an adjacent spinous process which protrude from the vertebrae, on the outer circumference of the spinous process and on the outer circumference of the adjacent spinous process so as to mutually fix the spinous process and the adjacent spinous process; and a spacer unit which is coupled to the band unit and is disposed in a space between the spinous process and the adjacent spinous process so as to fix the end of the band unit, wherein the spacer unit moves along the band unit from the outside of the body to the inside of the body in a state where the band unit penetrates the spacer unit, and thus the spacer unit is inserted into the space between the spinous process and the adjacent spinous process. Thereby, the spacer device can: efficiently and reliably fix the end ofa band for mutually fixing adjacent spinous processes, while permitting fine motion during surgery for treatment of spinal diseases; acquire optimal procedure results and efficiently carry out surgical procedures regardless of skill due to a relatively inexpensive and simple configuration; take action in accordance with the body types of various patients; and provide a patient with a state identical to that of original vertebrae since a firmly fixed state can be maintained and, simultaneously, fine motion is permitted following a procedure.

Description

technical field [0001] The present invention relates to a spacer device for fixation of the interspinous process band, more particularly, relates to a spacer device for fixing the end of the band in the operation for treating spinal diseases such as spinal stenosis, degenerative disc disease, etc. A spacer device for fixation of interspinous process bands of , wherein the bands fix adjacent spinous processes to each other and allow for minute movements. Background technique [0002] The spinal canal is the passageway through which the spinal nerves travel. Holes at the back of each vertebra connect up and down to form the tunnel through which nerves travel from the brain to the extremities. [0003] If the passage through which such spinal nerves pass is narrowed, it compresses the nerves, exposing diseases that feel severe pain, such as spinal stenosis. [0004] The most common spinal disease can be called degenerative spinal stenosis. [0005] This type of degenerative s...

Problems solved by technology

[0008] However, the problem with the previous spinal implants is that the upper and lower spinous processes move independently instead of together because the upper and lower spinous processes are not fused. Therefore, the long-term movement of the spine not only damages the spinous processes, but also causes the spinal implants to move from the spine to the spine. disengagement

[0009] In addition, there is a problem that in order to insert the spinal implant between the spinous processes, it is necessary to cut the ligament from the back and insert it, so the operation time is long, and the recovery time of the patient after the operation is also long.

[0010] In addition, there is a problem that the spinal implant cannot be connected to the upper and lower spinous processes because the wings fastened to the upper and lower spinous processes after being inserted between the spinous processes are not configured to be properly adjustable according to the thickness of the spinous processes. fully reliable fastening

[0011] In addition, this spinal implant has a problem in that the angle or width formed by the spinous process and the adjacent spinous process varies depending on the body size of the patient, making it difficult to operate

[0012] In particular, this conventional spinal implant has problems in that it requires a lot of production costs related to mold design, and its structure is complicated, so it is economically inefficient

[0013] In addition, there is a problem with conventional spinal implants: As mentioned above, the structure is complicated, so a high degree of proficiency is required for the operation
