The replaceable orthopaedic curet of a kind of double endTechnical field
This utility model relates to technical field of medical instruments, the replaceable orthopaedic curet of especially a kind of double end.
Background technology
Cervical spondylosis, prolapse of lumbar intervertebral disc disease are disease common in Orthopedic Clinical, the Lumbar intervertebral disc protrusion tissue of pressuring nerve, the hyperplastic tissue etc. of calcification are removed in usual needs operation, often to carry out scraping bone operation in operation process, the instrument mainly curet of bone is scraped in existing operation, but there is function singleness, complicated operation, easily causing the shortcomings such as secondary injury because skidding in existing curet, adds the work load of medical personnel and the misery of patient.
Utility model content
The purpose of this utility model provides a kind of double end replaceable orthopaedic curet to overcome above-mentioned technical disadvantages.
The technical scheme that this utility model technical solution problem adopts is: the replaceable orthopaedic curet of a kind of double end, comprise circular cutting edge key bit, square cutting edge key bit, two spoon bars and handle, described circular cutting edge key bit is connected respectively by the fixture of spoon bar with handle two ends with square cutting edge key bit, described handle inner is provided with liquid storage pipe, and the two ends of described liquid storage pipe are connected respectively by the catheter of spoon bar inside and circular cutting edge key bit and square cutting edge key bit.
Described handle and liquid storage pipe same position are provided with opening, described opening is provided with lid, described lid is provided with handle.
Be provided with female thread in described fixture, described spoon bar and fixture link position are provided with the external screw thread matched with female thread.
Described spoon bar is provided with graduation mark.
Described handle is provided with anti-slip veins.
The beneficial effect that this utility model has is:
This utility model reasonable in design, easy to operate, two of handle is provided with different curets, in operation, avoid the time waste that medical personnel cause because changing operation tool, spoon bar is set to motion bar, is convenient for changing different curet, cost-saved, spoon bar is provided with graduation mark, the degree of depth that key bit enters can be grasped, dramatically reduce the work difficulty of medical worker.

Detailed description of the invention
Be described below below in conjunction with accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3 pairs of this utility model.
As shown in Figure 1, Figure 2 and Figure 3, this utility model comprises circular cutting edge key bit 1, square cutting edge key bit 6, two spoon bars 5 and handle 4, described circular cutting edge key bit 1 is connected respectively by the fixture 3 of spoon bar 5 with handle 4 two ends with square cutting edge key bit 6, described handle inner is provided with liquid storage pipe 11, and the two ends of described liquid storage pipe 11 are connected with circular cutting edge key bit 1 and square cutting edge key bit 6 respectively by the catheter 12 of spoon bar 5 inside; Described handle 4 and liquid storage pipe 11 same position are provided with opening 9, described opening 9 is provided with lid 10, described lid 10 is provided with handle 7; Be provided with female thread 14 in described fixture 3, described spoon bar 5 and fixture 3 link position are provided with the external screw thread 13 matched with female thread 14; Described spoon bar 5 is provided with graduation mark 2; Described handle 4 is provided with anti-slip veins 8.
When using this utility model, the spoon bar 5 of required key bit is rotatably connected with fixture 3, hold handle 4, anti-slip veins 8 on handle 4 can prevent from skidding, the penetration depth that convenient observation key bit is set of graduation mark 2, required curet is goed deep into carry out in human body scraping bone, the chip scraped or hydrops enter in liquid storage pipe 11 by catheter 12, after scraping bone, the lid 10 on opening 9 is opened by handle 7, the refuse scraping taking-up is discharged, when needs carry out replacing key bit, spoon bar 5 and fixture 3 reverse direction are rotated and can take off, easy to operate, can extensively spread to various big hospital orthopedics clinic practice.
