Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of novel canalis spinalis perching knife.
Background technology
Clinically, part spinal canal stenosis is to cause the neural blood vessel adhesion that is inflamed because the cause of disease such as intervertebral disk hernia, hyperosteogeny stimulates spinal cord, nerve and peripheral vessels, congestion and edema " swells ", thereby cause the generation of spinal stenosis, proliferation and outstanding unnecessary tissue are excised, and are the effective means of this class case for the treatment of.Clinical common employing canalis spinalis perching knife removes unnecessary tissue lifter, and current canalis spinalis perching knife function is comparatively single, and it can only move to shovel by extrapolation and cut, the suitability is not high, especially do not there is the function of striking off, in clinical manipulation, have very large inconvenience, impact operation efficiency; Its blade is without positioner, easily slippage in operating process, and other positions are damaged.In addition, canalis spinalis perching knife is in the time of work, and cutting edge place easily adheres to the tissue substance cutting, and sword face can not fully be exposed, and affects operation technique, the collection that is also unfavorable for excising thing simultaneously.
Utility model content
For overcoming above-mentioned technical problem, this utility model provides a kind of reasonable in design, convenient to operation, and tissue lifter is except effective, and operation efficiency is high, and can avoid shovel to cut the novel canalis spinalis perching knife of shovel board slippage in process.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of novel canalis spinalis perching knife, comprise one handle, and the front end of handle is provided with perching knife, and the front end of perching knife is provided with blade, it is characterized in that: described blade is provided with an anti-slip breach; The upside of described perching knife is placed with a sliding panel, and the rear end of sliding panel is provided with sliding handle, and front end is provided with the scraper of hook solid, and the blade of scraper tilts to back upper place; The front sliding sleeve and the rear sliding sleeve that before and after being equipped with on described perching knife, distribute, described front sliding sleeve is fixedly connected with the front end of sliding panel, and described rear sliding sleeve is fixedly connected with sliding handle; Between described rear sliding sleeve and perching knife, be provided with the detent mechanism being formed by location hoodle and locating hole; Described perching knife sidewall is provided with the rear sliding sleeve limited step that sliding position limits forward.
Described rear sliding sleeve, in the time that it is positioned at foremost before sliding sleeve be just in time positioned at the blade place of perching knife, the tissue adhering on the blade of perching knife easily can be pushed thus.
The utlity model has following beneficial effect: when sliding panel is pushed into rearmost end, scraper and front sliding sleeve are all positioned at the rear of perching knife blade, can use equally with perching knife in the past; When on the blade of perching knife, be stained with cutting under organize time, promoting forward sliding panel can clear up the tissue adhering on blade get off by front sliding sleeve, avoids hindering perching knife work; In the time that sliding panel is positioned at forefront, can strike off by utilizing scraper to shovel to inconvenience the tissue of cutting.It is simple in structure, convenient to operation, has that shovel is cut, struck off, anti-slip function, also can clear up the blade bur of perching knife, has improved operation efficiency, has brought convenience to doctor.
