Abstract

A distracting instrument acting between spinous processes comprises a capsule made of a biocompatible material and is characterized in that the capsule is prepared from a weakly elastic material. After being filled with a substance, the capsule forms a structure with two wings, connection is set at the middle of the two wings, and recessions matched with an upper spinous process and a lower spinous process are formed at the middle of the two wings during the placement. One side of the top of the capsule is provided with an inflating or liquid-filled filling port, the middle of the top of the capsule is provided with an anti-adhesion colloid structure, and the top of the capsule is provided with an image mark. During use, the unfilled capsule is set to a surgical site, material filling is performed on the capsule through the rear end filling port after the implanting, so that the whole operation is much smooth, an implanted structure is smaller, and a required surgical opening is smaller. In addition, a capsule implanting instrument is arranged and includes an implanting sleeve, and a filling pipe and a pair of spinous process distracting pincers are disposed in the sleeve. The distracting instrument is characterized in that a capsule setting pipe is further disposed in the sleeve, a hard filling pipe is disposed in the capsule setting pipe, and the filling pipe is connected with the filling port on the capsule.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for vertebral body surgery, in particular to an instrument used in the minimally invasive surgical treatment of lumbar degenerative diseases; in particular, it relates to a distraction instrument acting on interspinous processes. Background technique [0002] Now as people grow older, the lumbar spine will show different degrees of natural degeneration. Degenerative lumbar spine diseases often seriously affect the daily life of patients, and some even lose their ability to take care of themselves. It is a common disease in orthopedics. According to foreign literature reports, about 50% of adults in Western countries have suffered from low back pain, and about half of them need to see a doctor; in my country, about 1 case per 1,000 people per year with degenerative lumbar disease requires surgery. For a long time, lumbar fusion and internal fixation has been generally recognized as the ...
