Description
Technical Field
The utility model belongs to the technical field of the sleeve pipe, specifically indicate a locking sleeve pipe.
Background
In the treatment of disc herniation, the intervertebral foramen is usually narrow in the case of a herniated disc. The affected nerve roots emerge from the cephalic side, often surrounded by fibrous tissue or bony vertebral bodies. In order to ensure that the working channel can safely reach the cavity of the vertebral column, a trepan is used for cutting off the hyperplastic bone at the far end of the facet joint and a part of the upper joint bulge to enlarge the intervertebral foramen, so that the working channel of the spinal endoscope reaches the cavity of the vertebral column, and a surgical instrument is used for removing the herniated nucleus pulposus tissue, thereby achieving the purpose of treating the prolapse of the intervertebral disc.
The existing trephines in the market directly enter soft tissues, once the trephines contact bones, the trephines rotate clockwise to cut bone tissues, and after the trephines are finished, the trephines directly withdraw, so that nerves can be stimulated or damaged, and meanwhile, the soft tissues are damaged. Not only the aim of relieving the pain of the patient and reducing the complication is not achieved, but also the risk of the operation is improved. At present, the trepan with the protective sleeve is not high in handling control performance during operation; the saw rod is easy to slide in the protective sleeve due to the lack of a locking structure for the saw rod, and when the protective sleeve is placed in a spinal column part, sawteeth at the lower end of the saw rod are exposed.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a locking sleeve adopts the mode that glass bead prelock and the complete locking of steel ball combined together, has solved the easy roll-off of traditional sleeve pipe, and insecure technological problem has realized the technological effect of dual safety protection locking, has effectively solved the locking sleeve effect difference in the existing market, and self structure is complicated, maintains comparatively inconvenient problem.
The utility model adopts the following technical scheme: the utility model relates to a locking sleeve, including outer tube, interior sleeve pipe, glass pearl, sliding block, fixed block, steel ball and spring, interior sleeve pipe is located in the outer tube, the glass pearl is located on the outer tube, the fixed block is located on the outer tube, the sliding block slides and locates on outer tube and the fixed block, the steel ball is located between outer tube and the sliding block, the outer tube outside is located to the spring and just is located between fixed block and the sliding block.
Further, the lower extreme of sliding block is equipped with recess one and recess two, the height of recess one is greater than the width of recess two.
Further, the diameter of the steel ball is equal to the height of the second groove.
Further, the outer diameter of the inner sleeve is equal to the inner diameter of the outer sleeve.
Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the utility model provides a locking sleeve pipe, adopts the mode that glass bead prelock and the complete locking of steel ball combined together, has solved the easy roll-off of traditional sleeve pipe, insecure technological problem, has realized the technological effect of dual safety protection locking, has effectively solved locking sleeve pipe effect poor on the existing market, and self structure is complicated, maintains comparatively inconvenient problem.
