Abstract
The invention discloses a closed reduction surgical frame for tibial fracture of a patient, and relates to a medical instrument for orthopedic surgery. The surgical frame mainly comprises a movable triangular surgical frame body. The triangular surgical frame body comprises a base frame, a front bracket and a rear bracket. A connection mode of the closed reduction surgical frame includes that front bracket upper adjusting screws on two sides of the front bracket and rear bracket upper adjusting screws on two sides of the rear bracket are correspondingly movably connected with one another by concentric shafts and rotary fixing nuts to form two independent support pillars, so that thigh fixing supports are jointly formed. The base frame is movably connected with the other end of the rear bracket by a base frame fixing rod. A fixing clamp shaft at the other end of the front bracket is movably connected with one of clamp grooves of the base frame. The closed reduction surgical frame has the advantages that a continuous traction effect can be realized during closed reduction for the tibial fracture of the patient, and the stability of reduction and the stability of a fracture end of the patient are maintained; compression on the nerves of the local popliteal blood vessels of the patient due to traction is prevented; flexion and extension angles of the knee joint of the patient can be adjusted at any time as needed during surgery, and the closed reduction surgical frame is simple in structure and easy to operate.
Description
Technical field
The present invention relates to a kind of bone surgery medical apparatus and instruments, particularly a kind of fracture of tibia closed reduction operation bracket.
Background technology
Current fracture of tibia closed reduction, mainly comprise artificial manual reduction and use Special reset instrument two classes that reset.
One, artificial manual reduction
At present, artificial manual reduction is still a kind of reset mode that the fracture of tibia closed reduction is commonly used.Reset operation needs to complete under many people's cooperations, and the reverse traction by the far and near end of fracturing, make fracture end reduction.Owing to manually drawing, resetting and remaining unstable, usually need repeatedly reset, repeat perspective, sometimes also to go the fracture end open reduction, obviously affected the operation quality of fracture of tibia, also increased the intake of patient and medical worker x line simultaneously.
Two, the Special reset instrument resets
" tibia cross locking marrow nail surgical retractor resetting frame " that application (patent) number is 200720110055.3 is a kind of operation reduction by traction frame consisted of parts such as support, draw bar, guide posts.The reset mode of this device is: a pair of active force and the counteracting force that between large leg support and pedal, form when going down on one's knees make the traction of fracture of tibia end, reset.Because large leg support is not exclusively parallel with tibial shaft with the line between pedal, at a certain angle between the direction of formed power and counteracting force and tibial shaft during traction.Reset mode with respect to parallel tibial shaft traction, in the situation that produce same pull strength, it is larger that this installs required power, the easily compressing of Zao Cheng popliteal nervus vasculairs and the stretch injury of common peroneal nerve, and also easily cause the front and back displacement of fracture end perpendicular to the component of tibial shaft direction.Fixing distal femur carrier structure can not need to adjust knee joint angle according to operation simultaneously, owing to lacking the holdout device of going down on one's knees, draws, while resetting, need control for a long time kneed flexion, is prone to and remains unstable.And the opacity of this device to the x line, make it in reduction of the fracture process, can hinder different directions x ray examination.Therefore, limited this resetting means in clinical extensive use.
Summary of the invention
Main purpose of the present invention is, by a kind of device that makes fracture of tibia reach the closed reduction effect, eliminates above-mentioned defect, realizes continuous traction, maintains and reset and fracture end stable.
Second purpose of the present invention be, obtaining a kind ofly can need in art to adjust at any time knee joint angle according to operation, and make fracture of tibia reach the operation device of closed reduction.
The 3rd purpose of the present invention be, obtains a kind of fracture of tibia traction, while resetting, Dui Ju Bu popliteal nervus vasculairs do not cause compressing, and make fracture of tibia reach the operation device of closed reduction.
The 4th purpose of the present invention is, obtains a kind of simple in structure, convenient sterilizing, just can maneuverable operation device without patient's proficiency level, experience.
The 5th purpose of the present invention be, obtains a kind of transparently to the x line, in fracture of tibia closed reduction operative process, can not hinder the operation device of different directions x ray examination.
Technical scheme of the present invention is as follows: a kind of fracture of tibia closed reduction operation bracket is characterized in that: by underframe, front rack, tail-bracket, is jointly formed one can activity the triangle operation bracket.Described underframe is rectangle, and by the rectangular tube with draw-in groove, with the underframe stationary pipes, is fixedly connected with and forms.There is adjusting screw(rod) under the front rack adjusted screw rod of reverse screw tap and front rack the upper and lower both sides of described front rack, and between screw rod, by two ends, the front rack adjusting nut with corresponding screw tap is connected.There is adjusting screw(rod) under the tail-bracket adjusted screw rod of reverse screw tap and tail-bracket the upper and lower both sides of described tail-bracket, and between screw rod, by two ends, the tail-bracket adjusting nut with corresponding screw tap is connected.The tail-bracket adjusted screw rod on the front rack adjusted screw rod on described front rack both sides and tail-bracket both sides, by concentric shafts and the female flexible connection of rotary fixing screw, form two independently support columns, jointly forms the thigh fixed support.There is the tail-bracket fixed bar below of described tail-bracket thigh fixed support.Described underframe is with respect to the other end of draw-in groove, by the other end flexible connection of underframe fixed bar and tail-bracket.Described front rack has the draw-in groove of fixing axis and underframe to be flexibly connected with respect to the other end of thigh analog bracket.The top of described front rack axis, have and front rack ankle fixed support connected vertically.Described ankle fixed support is square, by four round tubes, is fixedly connected with and is formed.
All parts of the present invention is preferably made by the material to x line highly transparent, but also can be formed by other material.
The present invention can provide continuous traction when the fracture of tibia closed reduction, maintains and resets and fracture end stable.Can not cause because of traction the compressing of Ju Bu popliteal nervus vasculairs.Can stretch angle in the wrong, simple in structure, easy operation according to needing to adjust at any time knee joint in art simultaneously.Therefore, the present invention has substantive distinguishing features and marked improvement.
