Description
Technical field
This utility model relates to a kind of medical apparatus, especially improves the pin cutter.
Background technology
Pin cutter medical science is a kind of clinical therapeutic method of surgery and medicine principle of at home and abroad being widely used in.Traditional pin cutter is made up of the shank of metal handle and band blade.During operation, it cuts, peels off, loosens through the subcutaneous patient's diseased region that directly thrusts, be useful for various soft tissue injurys and bony spur, hyperosteogeny, femur head necrosis, ankylosing spondylitis etc., it is easy to use, determined curative effect, but the conventional needle cutter is insufficient be: 1: reuse, cross infection or sterilization take place easily nosocomial infection does not thoroughly take place; 2: use several times repeatedly, cutting edge meeting rust or turned increases misery to the patient; 3, conventional needle edge width is generally 0.8mm, and for the general joint of treatment, the hyperosteogeny diseases curative effect is not ideal enough; 4, the conventional needle cutter needs sterilization, and a pin cutter use all can not continue to use because of turned, naked sword several times again, and cost is big; 5, the conventional needle handle of a knife is a flat, skids easily, is difficult for being affectedly bashful counter holding; 6, traditional shank does not have scale, and entering the interior degree of depth of patient's body does not have data visualization.
The utility model content
Technical assignment of the present utility model is to provide a kind of improvement pin cutter at above-mentioned deficiency of the prior art, this improvement pin cutter has can effectively stop cross infection, when alleviating patient's art pain and be easy to the patient be affectedly bashful control, characteristics that shank enters depth visual in patient's body, reduces the cost.
The technical scheme that its technical problem that solves this utility model adopts is: it comprises shank and syringe needle, syringe needle is arranged on the top of shank, described syringe needle is two-sided wedge shape flat blade shape shape, shank is cylindrical, shank and syringe needle are stainless steel, are connected with needle handle in the bottom of shank, needle handle thickness attenuation gradually from the top down, longitudinal surface is one trapezoidal, and the front and back of needle handle symmetry respectively caves inward.
Described pin cutter total length is 70-100mm, the long 15mm of described needle handle, and wide 20mm, top thickness is 5mm, and bottom thickness is 4mm, and the thickness that forms in the middle part of the needle handle two sides caves inward is 1.2mm, and described shank diameter is 0.3-1.2mm, the wide 0.3-1.2mm of syringe needle.
Described shank is provided with scale.
Described needle handle is made for the milky plastics.
Improvement pin cutter of the present utility model is compared with prior art, have following outstanding beneficial effect: the front and back of needle handle symmetry respectively caves inward, the patient is affectedly bashful in convenience, the operation in use is difficult for landing, handy, lower the operation error greatly and alleviated the patient suffering, shank indicates scale, make operation more accurate, stop cross infection, characteristics such as reduce the cost.
