Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of nail taking out apparatus in orthopaedics.
Background technology
In clinical medicine, fracture is common bone wound disease, and treating fracture most common method is implement internal fixation operation, is namely coupled together by skeleton with blade plate and steel nail, after waiting to heal, is taken off by steel nail.The mode taking nail is also a lot, as being inserted in screwdriver in the nail groove of the nail head of a nail, slowly rotating until being drawn off, this way not only troublesome poeration, wasting time and energy, and when nail groove is worn destruction accidentally, nail is difficult to take out.
nullIn bone surgery，Rehabilitation for patient，Generally use screw that fracture portions is fixed，Therefore it is highly important for the fixing screw of the patient after rehabilitation being taken out，Device for taking out fixing screw in orthopaedics is an important armarium，Simultaneously，Some screw retention time in vivo is long，Thus in the functional exercise lacking rationally guidance or in work，Due to stress-shielding effect，Segment screw nail meets with stresses huge，Easily caused by fracture，Especially the application of titanium alloy，Add histocompatibility，Screw and sclerotin are tightly combined，Thus just likely nut and breechblock are twisted into two parts when taking out screw，Thus the case that broken nail is in clinic is more typically，Device for taking out fixing screw in orthopaedics common at present is manual trepan，Owing to it is unidirectional and without scale，Not only technique falls behind，Waste time and energy，And some operation nail length is longer，It is not easily taken out，Take force during nail careless，Easy drop is followed closely in operation，Stay the nail of the operation in patient body to be not easily taken out，Add the misery of patient.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, it is provided that a kind of simple in construction, nail taking out apparatus in orthopaedics reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises the quiet frame of L-type, holder limb groove, bundling belt, operation nail fixed mount, L-type moving frame, lasso, hand ratchet, carrying bearing pin；Being provided with holder limb groove and bundling belt on the upside of the stull of the quiet frame of described L-type, its perpendicular support side is provided with hand ratchet, and the top of perpendicular support is further fixed on the lasso of rectangle；The perpendicular support of L-type moving frame is through lasso；The crossbeam of described L-type moving frame is fixedly connected with operation nail fixed mount by carrying bearing pin；Described operation nail fixed mount comprises fixing sleeve, operation head of a nail clamp port；The lower port of described fixing sleeve and be internally provided with several operation head of a nail clamp port.
As preferably, described fixing sleeve lining is provided with screw thread.
As preferably, the number at least two of described operation head of a nail clamp port.
During this utility model operation, shake hand ratchet, make the head of a nail that operation is followed closely be fixed in operation head of a nail clamp port, then shake hand ratchet, carry out taking tack operation；In taking-up process, the taking-up length according to operation nail, the head of a nail can move up, it is to avoid force is careless, drop.
After adopting said structure, what this utility model produced has the beneficial effect that a kind of nail taking out apparatus in orthopaedics described in the utility model, longer operation nail can be easily removed, and operation nail is not easily broken, decreasing the misery of patient, this utility model has simple in construction, arranges the advantages such as reasonable, cost of manufacture is low.
