Description
Technical field
It the utility model is related to medical field, and in particular to one kind can make deep visual area clearly and have mousing-hook function
Laminectomy retractor.
Background technology
Laminectomy retractor is widely used in posterior lumbar spinal surgery, and traditional laminectomy retractor front end is only being used with a drag hook
During easily break off relations, since the wound of spinal operation generally can be smaller and deep, the shadowless lamp on operating table has
Shi Buneng reaches deep visual area, causes visual area unintelligible.Since spinal operation belongs to delicate procedure, visual area is unintelligible damage ridge
The risk of marrow and nerve root, can also cause operation risk to increase, and extend the pain of operating time increase patient.Vertebra in surgical procedure
The transverse arm of plate drag hook can inevitably be stained with the liquid produced during operation, and can reduce frictional force makes laminectomy retractor operating difficulties.
Utility model content
In view of the deficiencies of the prior art, it can make deep visual area clearly the purpose of this utility model is to provide one kind and have
There is the laminectomy retractor of mousing-hook function.
The technical problem that the utility model solves can be realized using following technical scheme：A kind of laminectomy retractor, including
Into the transverse arm and vertical arm at 135 ° of angles, and the metallic channel being arranged on transverse arm and vertical arm, the end of transverse arm is equipped with outward bending
Non-slip hook pull rod, the end of vertical arm are equipped with arc-shaped draw hook, and the end of the vertical arm is equipped with LED light, and the transverse arm is equipped with
The power supply and switch being connected by conducting wire with LED light, and transverse arm surface is equipped with anti-skidding annular knurl, the LED light, power supply, open
Pass is connected with conducting wire and insulated paint has been sprayed in the exposed source of conducting wire, and the power supply is button cell, the vertical arm
The arc-shaped draw hook of upper setting is two, and the LED light is arranged between two arc-shaped draw hooks, and the arc-shaped draw hook is solid
Construction, arc-shaped tapered structure, the metallic channel is semicircular conductor groove, and diameter is slightly less than diameter of wire.
Beneficial effect：The transverse arm can increase the visual field to the utility model with vertical arm into 135 degree of angles in use,
Anti-skidding annular knurl on the transverse arm can be with increasing friction force, and having done insulation processing to LED lamps, power supply and conducting wire can ensure
Use reliability of the LED light in surgical procedure, the metallic channel are processed on laminectomy retractor surface, so metallic channel
Difficulty of processing will be greatly lowered, the arc-shaped draw hook have two in use being capable of effectively anti-locking hook and handle
Holding force is preferable, and the power supply can be that LED light is powered, and the switch can control the light on and off of LED light, and LED light can be to visual area
Light source is provided, makes deep visual area clear, therefore operational risk in art can be reduced, shortens operating time, intraoperative hemorrhage is reduced, allows
Patient is benefited, and LED light has the advantages that small, brightness is high, little power consumption, and LED light be arranged on two arc-shaped draw hooks it
Between, do not interfere with arc-shaped draw hook and pull open tissue.

Embodiment
Describe the preferred embodiment of the utility model in detail below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 show a kind of laminectomy retractor of the utility model, including transverse arm 1 and vertical arm 2 into 135 ° of angles, and set
Metallic channel 3 on transverse arm 1 and vertical arm 2, the end of transverse arm 1 are equipped with the non-slip hook pull rod 4 of outward bending, and the end of vertical arm 2 is set
There is arc-shaped draw hook 5, the end of the vertical arm 2 is equipped with LED light 6, and the transverse arm 1 is equipped with to be connected by conducting wire with LED light 6
Power supply 7 and switch 8, and 1 surface of transverse arm is equipped with anti-skidding annular knurl 9, and metallic channel 3 can play the role of fixed conducting wire, LED light
6 can play the role of illuminating deep visual area, the anti-skidding annular knurl 9 on 1 surface of transverse arm can increase frictional force, during preventing use
Laminectomy retractor slides.
In the present embodiment, the LED light 6, power supply 7, switch 8 connect and the exposed source of conducting wire is sprayed with conducting wire
Insulated paint is gone up, the power supply 7 is button cell, and LED can be ensured by having done insulation processing to LED light 6, power supply 7 and conducting wire
Use reliability of the lamp 6 in surgical procedure.
In the present embodiment, the arc-shaped draw hook 5 set in the vertical arm 2 is two, and the LED light 6 is arranged on two
Between a arc-shaped draw hook 5, it can not increase wound while the visual field is expanded using two arc-shaped draw hooks 5, LED light 6 is set
