Description

Expansion balloon system for creating muscle-bone gap space of lumbar posterior endoscope

Technical Field

The utility model relates to the technical field of surgical instruments, especially, relate to an expansion sacculus system that creates lumbar vertebrae way of escape scope muscle-bone clearance space.

Background

When soft tissue on the lumbar vertebrae way of escape scope operation processing vertebral plate, the way of escape scope is handled the vertebral plate clearance soft tissue down, often runs into the soft tissue and blocks, utilizes the sacculus expansion vertebral plate top soft tissue within a definite time, makes a cavity, reduces the disconnected damage of separating of soft tissue, simultaneously more rapidly made a cavity, can fixed direction and space, the scope is more difficult to lose or lost the way under the operation. Endoscopic surgeons often have poor treatment of soft tissues, which results in the occlusion of the visual field by the soft tissues and the bleeding during the operation, so that the operation time is prolonged and even the operation cannot be performed.

The operation duration has a close relation with the effect of the operation and the recovery in the perioperative period, and in the current clinical operation, the common technical means is to use a stripper to strip the muscle attachment on the vertebral plate by the hand feeling of a doctor so as to realize the range and the width of the operation space under the endoscope. Often, the operation visual field is unclear due to insufficient stripping, or bleeding is caused due to excessive stripping to hurt blood vessels, which brings great trouble to operators.

The existing vertebral plate-muscle space creation treatment operation process is manual operation, so that the time consumption is long, the range and the width of the vertebral plate-muscle space creation treatment operation process are judged by a doctor subjectively, the bleeding visual field is unclear due to the fact that muscle fibers are easily damaged and broken and even blood vessels are damaged in the stripping process, and a large amount of time is consumed for hemostasis and soft tissue shrinkage treatment.

Therefore, the design of the balloon dilatation system which can be fast and efficient, can expand the range and provide accurate space size to create the muscle vertebral plate soft tissue space has important clinical significance.
