Abstract

An embodiment of the invention discloses a spinal posterior adjustable operation retractor. The retractor comprises a mobile arm and a fixed arm which are connected through a gear and a rack, and further comprises step-by-step extension rods and drawing blades. One end of the mobile arm and one end of the fixed arm are connected with the step-by-step extension rods respectively. The drawing blades are arranged on the corresponding step-by-step extension rods, wherein one end of each drawing blade is provided with insertion portions, and the drawing blades are fixed to the corresponding step-by-step extension rods through the insertion portions and vertical to the step-by-step extension rods; toothlike protrusions are arranged at the other end of each drawing blade, the toothlike protrusions and the insertion portions are arranged on the same sides of the drawing blades, and the toothlike protrusions are used for being in contact with a human body. According to the spinal posterior adjustable operation retractor provided by the embodiment, length and depth are adjustable, exposure of view of long-section spinal operation is guaranteed, and smooth performing of subsequent operations is ensured.

Description

Technical field [0001] The invention relates to the technical field of medical instruments, and in particular to an adjustable surgical retractor for the posterior spinal column. Background technique [0002] Posterior spine surgery is one of the commonly used clinical surgical methods to treat spinal diseases. Posterior spinal surgery includes cervical, thoracic, and lumbosacral posterior surgery. During the surgery, the paravertebral muscles and ligament tissues need to be retracted to both sides to expose the spinous processes and lamina in the middle to facilitate vertebral operations. For follow-up operations such as tube decompression, internal fixation, and bone graft fusion, the function of the surgical hook is to retract the soft tissues such as the muscles on both sides during the operation to prevent these structures from moving closer to the middle, blocking the exposure of the surgical field, and affecting the safety of the operation . At the same time, the posteri...
