Prior art adopts a kind of percutaneous discectomy device, uses the rotary-cut cutter head, under the help of iconography, from the close nucleus pulposus in the side of intervertebral disc, avoid bone structure, can intactly extract vertebral pulp, the post-operative complication shape of avoiding surgical operation to bring simultaneously.But, from the side near intervertebral disc, be easy to mistake run into around the intervertebral disc around nerve, give around the intervertebral disc around neural build-up of pressure, bring very big security risk to the patient.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of simple to operate, discectomy external member of using safety is provided.
This utility model adopts following technical scheme: a kind of discectomy external member, formed by a piercing assembly and a rotary-cut assembly, described piercing assembly is made up of puncture needle and handle, and an end of puncture needle rotatably is inserted in the handle, the other end forms spiral bit; Described rotary-cut assembly is made up of rotary-cut pin, sleeve pipe and handle, and the rotary-cut pin rotatably is inserted in the handle, and sleeve pipe is set in outside the rotary-cut pin movably, and the end of rotary-cut pin also forms the rotary-cut probe, and the outer peripheral face of this rotary-cut probe forms the helical form projection.
Aforementioned a kind of discectomy external member, the handle of described piercing assembly, rotary-cut assembly includes the one handle shell, in this handle casing and be provided with electric assembly, case surface also is provided with on and off switch, and the electric assembly in the handle of described piercing assembly, rotary-cut assembly connects puncture needle, rotary-cut pin respectively.
Aforementioned a kind of discectomy external member, the length of described spiral bit is 0.5～2mm.
Aforementioned a kind of discectomy external member, the length of described spiral bit is 1～1.5mm.
Aforementioned a kind of discectomy external member is equipped with scale marker on the sleeve pipe of the puncture needle of described piercing assembly, rotary-cut assembly.
Aforementioned a kind of discectomy external member, the diameter of section of described spiral bit is 1.4～1.6mm, and the external diameter of described sleeve pipe is 1.4～1.6mm, and internal diameter is 1.2～1.4mm, and the diameter of section of spiral bit is not less than the external diameter of sleeve pipe.
This utility model in use, under the help of iconography, at first pass skin with piercing assembly through human body back front, and in bone structure punching with near intervertebral disc, after punching finishes, piercing assembly is extracted, insert the rotary-cut assembly, utilize the rotary-cut assembly with the nucleus material rotary-cut and aspirate out external.
By above-mentioned to description of the present utility model as can be known, compared with prior art, a kind of discectomy external member of the present utility model utilizes piercing assembly and the ingenious of rotary-cut assembly to be used, pass skin through human body back front, and in bone structure punching with near intervertebral disc, avoid around the intervertebral disc pressure around nerve, direct nucleus material with intervertebral disc is removed and is aspirated out external, simple to operate, use safety, have very high popularizing value.
