Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of Medical wrist arthrocsopic surgery many positions traction frame.
Background technology
In recent years, carpal joint mirror Minimally Invasive Surgery technology quickly grows so that the wound of carpal joint operation is less, and patient's post-operative recovery is faster.But carpal joint gap is narrow and small, for the ease of operating under Arthroscopic inspection and mirror, it is both needed in operation, carpal joint be drawn.Existing carpal joint videoendoscopic surgery traction apparatus is typically vertical distraction, head tree is respectively positioned on carpal joint palmar center, by head tree, forearm and wrist straight are suspended in midair, therefore, it is difficult to the carpal joint palmar carrying out assisting in operation cuts or inserts the operation that inside-fixture is fixed simultaneously, at present practical operation needs to dismantle traction apparatus, by firm for upper limb level be positioned on small operating table the most convenient to operate.And now because losing traction, it is impossible to carry out the observation under arthroscope and monitoring simultaneously.Additionally, the head tree of existing traction apparatus is respectively positioned on carpal joint palmar center, if art carrying out X-ray examination can hinder shelves imaging.Therefore, research and develop a kind of many positions traction apparatus, except existing vertical distraction can be met, it is possible in the case of traction is maintained, easily forearm position is perpendicular between horizontal positioned adjustment；Meanwhile, traction frame adopt the new structure of head tree, it is to avoid the head tree stop to x-ray, is the art task of having needed.
Summary of the invention
It is an object of the invention to provide a kind of easy to use, the most reliable, it is simple in operation process, patient's carpal joint is carried out Medical wrist arthrocsopic surgery many positions traction frame of the traction of many positions and X-ray examination.
nullIn order to reach object above，This utility model following structural principle of employing: a kind of Medical wrist arthrocsopic surgery many positions traction frame，By base plate、Fixing nut、Fixing seat、Head tree、Adjust column、Connecting rod、Cross bar、Shop bolt、Fixed board、Locking screw、Elevating screw，Locking handwheel、And pinch set composition,Its feature is: rectangular base plate longitudinal direction two ends downward bending becomes leg，In the plane of base plate one end，Fixing nut thread coordinates mounting-fixing base，Fixing seat one side elevation is end-tooth，The end-tooth corresponding with side, head tree lower end coordinates，Locked by screw thread rotation handwheel，The end-tooth of head tree upper end opposite side coordinates with the corresponding end-tooth of side, connecting rod lower end，Locked by screw thread rotation handwheel，Connecting rod upper end is hollow cylinder，In cylinder, basin and insertion adjust column，Locked by screw thread rotation handwheel，Adjust the column cylinder longitudinally upper and lower multiple positioning through hole of uniform arrangement，Adjustment column top is inserted in vertical through hole cooperation on cross bar one end，The shop bolt positioning through hole from termination, cross bar one end is fixing after inserting，The cross bar other end is horizontal vertical through slot，Screw-threaded coupling screw is fixed on vertical through slot，Elevating screw vertically coordinates screw-in screw-threaded coupling screw interior and passes the vertical through slot of cross bar，Interface unit set is fixed in elevating screw bottom；Two groups of longitudinal direction grooves and one group of horizontal groove is had in the plane of the base plate other end, fixed board lower end is parallel fixes two T-shaped posts of screw thread, correspondence is slided behind location in being inserted one group of two longitudinal directions groove arranged side by side, nut fixes the T-shaped post of screw thread, groove in fixed board plane overlaps vertical corresponding with pinching on elevating screw bottom, constitutes a kind of Medical wrist arthrocsopic surgery many positions traction frame.
Head tree of the present utility model uses end-tooth to be connected by connecting rod with adjusting column, can carry out swinging in the plane that base plate is horizontal and adjust plan-position, after determining position, locked by locking handwheel, the cross bar being arranged in adjustment column is by adjusting multiple positioning through hole of uniform arrangement on column cylinder, move up and down and carry out height and position adjustment, after determining position, it is fixed on the positioning by alignment pin, the upright position that vertical lift leading screw on the rotary bar other end realizes pinching set by locking nut adjusts, elevating screw is the transverse shifting in vertical through slot on cross bar, realize the position adjustment pinching set along base plate longitudinal direction, fixed board can carry out selecting to install in 3 groups of grooves on base plate, slip is fixing after determining position.Base plate uses aluminum alloy materials processing and fabricating, and under two ends, floor, the supporting leg of folding alleviates overall weight, has been also convenient for each portion of apparatus and has installed, and integral surface all carries out blasting treatment, it is to avoid in operation, metal surface is to Astral lamp light line reflection, disturbs surgical field of view.Overall structure is removable is divided into several parts, facilitates postoperative cleaning, sterilizes and deposit.
This utility model is in use, can be placed on fixed board according to patient's left hand and right hand and diverse location, with operation band, patient forearm is fixed, by adjusting the position pinching the hands that set is relatively fixed on riser, after position determines, after locking each movable part, the traction of many positions can be realized by pinching the pull rope connection patient's left/right hand put.
The paraxonic structure of the multi-directionally regulation that this utility model uses, Stability Analysis of Structures, easy to use, the most reliable, it is simple in operation process, patient's carpal joint to be carried out the traction of many positions and carry out X-ray examination observation and monitoring, having reached goal of the invention.
