Embodiment Construction

[0008] Embodiments are described in detail in conjunction with the above accompanying drawings, as figure 1 As shown, the cold light source lamina retractor is composed of hook process 1, retractor body 2, light source mirror tube 3, handle 4, fixed hook 5 and connector 6, the handle 4 is a cavity, and the axial direction of the handle is smooth The operating rod is bent and extended downward at 90o along the axial end of the handle, and the bent extension part is the retractor body 2, and the end of the retractor body shrinks inward to form a hook-shaped hook protrusion 1, and the cavity of the handle It is equipped with a light source mirror tube 3. The light source mirror tube is bent downward along the axial position of the handle and exposed to the hook body, which is also conducive to direct detection of lesions by focusing light. The other end of the light source mirror tube is exposed along the axial direction of the handle. , the exposed end of the light source mirror...

Abstract

The invention discloses a cold light source vertebral plate drag hook used during lumbar surgery. The cold light source vertebral plate drag hook consists of a hook protrusion, a drag hook body, a light source lens pipe, a handle, a fixed hook and a connector, wherein the handle is a hollow cavity; a smooth operation rod is arranged in the axial direction of the handle; the handle is downwards bent at 90 degrees along the tail end of the axial position of the handle to extend; the bent and extending part is the drag hook body; the tail end of the drag hook body is inwards retracted to form a hook shape, namely the hook protrusion; the light source lens pipe is arranged in the hollow cavity of the handle in a sleeving way; the light source lens pipe is downwards bent along the axial position of the handle to be exposed and tightly adhered to the drag hook body; the other end of the light source lens pipe is axially exposed; the connector is arranged at the exposed end of the light source lens pipe; the fixed hook which is downwards inclined is arranged at one end of the axial position of the handle.

Description

Technical field: [0001] The invention relates to a cold light source lamina retractor, which is especially suitable for use in lumbar spine surgery. Background technique: [0002] At present, during lumbar spine surgery, the skin is cut open, the muscles are pulled apart with common orthopedic laminar retractors, and curettes and rongeurs are used to maximize the stretch to eliminate the herniated tissue on the intervertebral disc. This technique is an open surgery with large surgical trauma, a high risk of bleeding or infection during the operation, more chances of complications after the operation, and a long hospital stay, which increases the economic burden of the patient. Invention content: [0003] The task of the present invention is to propose a kind of cold light source laminar retractor used in lumbar surgery with small trauma, easy operation and good therapeutic effect. [0004] The task of the present invention is accomplished in this way, a cold light sou...
