Description

A kind of laminectomy retractor

This utility model relates to a kind of laminectomy retractor technical field.

Existing laminectomy retractor is because the hook wing is the rectangle plate washer, thereby when spinal operation, retract spinal column muscle group compressing muscle group muscle ischemia, operating time has been grown also can cause myodegeneration, and the also unreasonable operator of making of the handle design of laminectomy retractor have held for a long time easy generation fatigue and pain in addition.

The purpose of this utility model is a kind of laminectomy retractor of design, has the fence groove on its hook wing, thereby oppressed muscle group is reduced, and handgrip is designed to elliposoidal good hand touch when the medical worker is operated, and is difficult for slippage.

This utility model is achieved in that the handle 2 butt hook wings 3, has fence groove 4 on the hook wing 3, and there is knop 1 handle 2 ends.

The utility model has the advantages that: novel, project organization is reasonable, and the oppressed muscle group that retracts when spinal operation reduces, and helps the healing of muscle group postoperative, and medical worker's long-time operation good hand touch is difficult for slippage.

Below in conjunction with accompanying drawing, this utility model is described further with embodiment:

Fig. 1 front view, Fig. 2 side view.

In the accompanying drawing: 1, knop, 2, handle, 3, the hook wing, 4, the fence groove.

The handle 2 butt hook wings 3, have fence groove 4 on the hook wing 3, there is knop 1 handle 2 ends, when to spinal operation, the medical worker holds knop 1, make the hook wing retract the spinal column muscle group with little articular process in sled top, the tip on the hook wing 3 or transverse process, the design of fence groove 4 makes the hook wing 3 reduce contact area to the spinal column muscle group.
