Description

Kirschner wire imports sight

This utility model relates to a kind of medical apparatus and instruments, and especially a kind of Kirschner wire imports sight.

Intertrochanteric fracture of the femur is a frequently-occurring disease, commonly encountered diseases, and Therapeutic Method at present relatively commonly used clinically is to adopt exterior fixation bracket and compression screw fixation to fix, it had both solved fixing, again can early functional exercise, be worth carrying out.But the importing of the Kirschner wire of external fixer and compression screw fixation guide pin exists technical difficulty: normotopia collodiaphyseal angle location can not one-time-reach-place during the penetrating of Kirschner wire, and need repeatedly thread a needle and take the photograph sheet or rely on the TV X-ray machine to confirm.When the Kirschner wire diagonal penetrates cortex, easy sliding transfer, the novice is difficult to once success.The axis of femoral greater trochanter and femoral shaft side position, the searching location of entry point and top rake, angle is held difficulty, and it penetrates success or not, needs postoperative to take the photograph lateral projection and determines.The patient needs the multi-pass operation experience, could use preferably.New hand's failure of once threading a needle easily slips into along former needle tray and repeatedly failure when penetrating once more.Operator will rely on experience, holds needle angle and penetrates technology, the location or under the TV X-ray machine, carry out of need threading a needle repeatedly when penetrating, and operating time is long, and patient is painful big, so vast basic hospital is difficult to use.

The purpose of this utility model is to provide a kind of Kirschner wire to import sight, this Kirschner wire imports sight and simplifies intertrochanteric fracture of the femur and the fracture of femoral neck fixed positioning action of threading a needle, and takes the photograph sheet or perspective number of times, shortens operating time and reach and alleviate patient's misery with minimizing.

The technical solution of the utility model: Kirschner wire imports sight and comprises bracing frame, slippage frame, scale stock, angle scale, trace, connecting rod, centring ring, the sleeve of threading a needle.The bracing frame base is positioned over big midleg or middle and upper part, and it is fixing to paste band with two.The slippage frame penetrates the Kong Zhongyong nut of the support column of bracing frame and fixes.Inner nut is enclosed within on the thread handle of trace, with the thread handle of the trace slippage slot by the slippage frame, again angle scale is inserted in thread handle, the scale stock penetrates in the hole of thread handle, tightens fixedly trace of nut.Connecting rod is connected in the connecting hole of slippage frame upper end, fixes with fixed screw.The thin bar of centring ring is inserted the connecting hole of connecting rod, fix with screw.Thread a needle telescopic holder and graduated disc are placed in the slippage slot of trace, and the sleeve of will threading a needle again passes through from the hole of holder, screws with inner nut, fixes holder and the sleeve of threading a needle.The sleeve of threading a needle is formed by the sleeve pipe intussusception that two thicknesses differ, and wherein tubule has not held two shell fragments to play support fixation in the bassoon, and tubule can stretch with respect to bassoon.

This utility model Kirschner wire imports the sight novel structure, and 1 normotopia collodiaphyseal angle locating rod is a kind of positioner that can determine the angle and the length of normotopia inserting needle.2 femoral greater trochanters and axis, femoral shaft side position body surface positioner.Side position greater trochanter and femoral shaft axis positioner can pin greater trochanter, to determine top rake and side inserting needle direction.3 traces interrelate normotopia collodiaphyseal angle locating rod and side position greater trochanter and femoral shaft axis positioner, and keep interlock, to keep the normotopia angle.4 thread a needle sleeve may command Kirschner wire swing and directions are convenient to diagonal and are threaded a needle, and have reduced the difficulty of threading a needle.Its retractility can freely be adjusted telescopic length to adapt to the distance of threading a needle.5 sleeves of threading a needle also can assist to anaesthetize inserting needle, make anesthesia position limitation and accurately, lower the anaesthetic consumption, have reduced the generation of anesthetic accident.Will guarantee simultaneously the safety operated to reduce cost as far as possible, simplified structure makes it be easy to dismounting, is easy to carry, and is economical and practical, finally applies.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Kirschner wire imports sight and comprises bracing frame, slippage frame, scale stock, angle scale, trace, connecting rod, centring ring, the sleeve of threading a needle.The bracing frame base is positioned over big midleg or middle and upper part, and it is fixing to paste band with two.The slippage frame penetrates the Kong Zhongyong nut of the support column of bracing frame and fixes.Inner nut is enclosed within on the thread handle of trace, with the thread handle of the trace slippage slot by the slippage frame, again angle scale is inserted in thread handle, the scale stock penetrates in the hole of thread handle, tightens fixedly trace of nut.Connecting rod is connected in the connecting hole of slippage frame upper end, fixes with fixed screw.The thin bar of centring ring is inserted the connecting hole of connecting rod, fix with screw.Thread a needle telescopic holder and graduated disc are placed in the slippage slot of trace, and the sleeve of will threading a needle again passes through from the hole of holder, screws with inner nut, fixes holder and the sleeve of threading a needle.The sleeve of threading a needle is formed by the sleeve pipe intussusception that two thicknesses differ, and wherein tubule has not held two shell fragments to play support fixation in the bassoon, and tubule can stretch with respect to bassoon.

This utility model Kirschner wire imports the using method of sight: the patient gets dorsal position, after first maneuver resets, and will suffer from limb in neutral of abduction slightly or slightly the inward turning position keep traction.Seek bone mark,, bracing frame is positioned over thigh stage casing (longitudinal axis of slippage frame serves as to indicate placement with the outer upper limb sideline of anterior superior iliac spine and patella) as anterior superior iliac spine and the outer upper limb of patella etc.Slippage frame, angle scale, trace, scale stock, thread a needle sleeve and angle scale are assembled respectively.Outer upward 5cm place is capital body surface projection sign with femoral artery body surface projection and inguinal ligament boundary, preliminary angle and the length of determining normotopia collodiaphyseal angle locating rod, the reuse hands is sought side position greater trochanter and is locked definite greater trochanter scope with positioner, cooperate the femoral shaft axis, the scale of viewing angle scale is with trace, scale stock, the sleeve of threading a needle locking.According to back X-ray film or the perspective situation of resetting, and, observe the length mark of scale stock, further adjust, the accurate position and the depth of needle of design inserting needle as standard.Select for use minute hand head (intracardiac pin) outside skin under the tuberosity 1% procaine or lignocaine to be soaked into cortical bone to the tuberosity, carry out local anesthesia by the sleeve pipe inserting needle of threading a needle.Cut an osculum with scalpel in the skin portion of inserting needle, extend and thread a needle sleeve pipe to cortical bone, squeeze into Kirschner wire or further accurately adjust angle and length by the sleeve pipe of threading a needle, squeeze into Kirschner wire again, Kirschner wire or guide pin promptly penetrate success.So far promptly finished location work, removed positioner, can carry out next step behaviour and do.
