Description

Improved Hofmann drag hook structure for knee joint
Technical Field
The utility model relates to the technical field of Huffman drag hooks, in particular to an improved Huffman drag hook structure for knee joints.
Background
At present, knee joint replacement operation is rapid in development, before a prosthesis is placed, muscle layers are required to be peeled off layer by layer, affected side joints are exposed, and bone hyperplasia and articular cartilage in joints are removed, and usually, exposure of a tibial plateau is insufficient when the tibial plateau is removed in knee joint replacement operation, so that operation vision is greatly disturbed, operation space of operators is affected, and operation time is prolonged.
At present, a Huffman drag hook is usually used for exposing a tibial plateau in knee joint replacement at home and abroad, the surgical field of view is enlarged, the invasive orthopedic surgery technology is still used up to now, the existing Huffman drag hook has limited exposure effect on the tibial plateau in surgery, the surgery difficulty and the risk are increased, meanwhile, a large proportion of patients in knee joint surgery are old patients, osteoporosis exists, the tibial plateau cannot be well exposed by the traditional drag hook, slipping is easy to occur, the bone injury of the tibial plateau of the patient with the osteoporosis is caused, the injury to surrounding tissues, blood vessels and nerves is possibly caused, and the defects of labor and long time consumption in the surgery exist.
Disclosure of Invention
The utility model aims to provide a knee joint improved Huffman draw hook structure.
In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a knee joint improvement huffman drag hook structure, includes main part drag hook dish, the both sides of main part drag hook dish are provided with two wing portions, one side fixed welding of main part drag hook dish has drag hook portion, the fixed welding in top of drag hook portion one side has handle portion, the through-hole pawl has been seted up on the surface of handle portion one side, the main part drag hook dish is provided with the pawl from the top of drag hook portion one side.
Preferably, the surface of the drag hook part is arranged to be concave.
Preferably, the overall shape of the handle part is semi-arc-shaped and is in a bent state.
Preferably, two sides of the main body drag hook disc are symmetrically provided with double wing parts, and the shape of the double wing parts is L-shaped.
Preferably, the material of the hook portion is the same as the material of the handle portion, and the material of the handle portion is a material with high hardness and difficult deformation.
Compared with the related art, the knee joint improved Huffman drag hook structure provided by the utility model has the following beneficial effects:
the utility model provides a knee joint improved Hofmann drag hook structure, which is characterized in that a main drag hook disc, a double-wing part, a drag hook part, a handle part, a through hole and a pawl are matched, so that the finger of a user passes through the through hole to finish wearing and using of the device, the whole handle part is in a downward tilted arc shape, the double-wing part can be well attached to the plane of the inner condyle and the outer condyle of an osteotomy femur so as to better expose a tibia platform, a user can conveniently clean and plane the bone tag at the rear side of the tibia platform, the pawl can grasp the bone surface so as to prevent slipping, the improved Hofmann drag hook is specially used for knee joint replacement operation, the position of the drag hook part can well hook the rear side of the tibia platform to fully expose the tibia platform, the slipping and accidental damage to the tibia platform are avoided, the structure is simple, the processing is convenient, and the use effect is good.
