Abstract
The invention relates to a femoral lesser trochanter reductor and a manufacturing method thereof. The reductor is characterized in that the middle of the reductor is a straight rod; two ends of the reductor are a handle part and an arc-shaped hooked needle part respectively; and a position 4 to 5 millimeters from a front tip of the hooked needle part is provided with a hole through which two steel wires can pass. The manufacturing method comprises the following steps that: one end of a medical stainless steel rod is ground into a cone shape; a hole 2 millimeters in diameter is bored in a position 4 millimeters from the tip side of the hooked needle part; one end of the steel rod is bent to be an arc, and the diameter of the arc is controlled within a range between 50 and 60 millimeters so as to apply to femurs different in diameter; the straight rod in the middle of the reductor is taken as a reductor rod; and the other end of the reductor is the rectangular or rhombic handle part easy to grasp by an operator. As the reductor can pass through a muscle gap attached to a lesser trochanter so as to lead in the steel wires, the lesser trochanter is convenient to reset by tightening up the steel wires. In addition, the reductor has the advantages of simple structure, manufacture easiness and capability of disinfecting under high pressure. Therefore, the reductor can be used as an orthopedic operation apparatus of femoral lesser trochanter reduction for a long time.
Description
Technical field
The present invention relates to a kind of bone surgery utensil and method thereof that lesser trochanter of femur is resetted, i.e. femoral lesser trochanter reductor and preparation method thereof.
Background technology
Intertrochanteric fracture of the femur with the lesser trochanter fracture is the difficult problem that present orthopedist faces, be all to need the lesser trochanter anatomical reduction with dynamic hip screw internal fixation or pedestrian worker's joint replacement, then indicate operative failure if lesser trochanter can not be resetted, and lesser trochanter adheres to owing to iliopsoas, in case displacement is difficult to free-hand resetting, existing holders etc. are quite complicated, be not easy to make, the cost height, and be not easy to autoclave sterilization and use, promptly do not have as yet at present conveniently to be used for the operation tool that lesser trochanter resets.
Summary of the invention
The purpose of this invention is to provide a kind of femoral lesser trochanter reductor and manufacture method thereof, it can remedy the above-mentioned deficiency of prior art, is difficult to reset and makes things convenient for fixed problem to solve the lesser trochanter displacement.
A kind of femoral lesser trochanter reductor, the centre that it is characterized in that this positor are that straight-bar, its two ends are respectively handle portion and crochet hook portion, and apart from crochet hook portion front tip 4-5mm place the hole that can pass two steel wires are arranged.
Manufacture method of the present invention is: the medical stainless steel rod of at first getting a diameter 4mm, wear into the one end coniform, again in the hole of the drill diameter 2mm of nearly most advanced and sophisticated side 4mm-5mm place of crochet hook portion, again with this end embowment, and making arcual diameter is 50mm-60mm, and to be useful for the femur of different-diameter, intermediary straight-bar is 150mm as the positor pole length, the other end is rectangle or the rhombus handle portion of long 80mm, so that operator grips.Utilize the coniform tip of its arc crochet hook portion to pass and be attached to trochantinian muscle gap, wear to lesser trochanter rear side introducing steel wire, with arc crochet hook portion along the cycle of former road, steel wire is drawn to the lesser trochanter front side, the steel wire two ends are tightened up, assist down lesser trochanter to be resetted and tightens steel wire in arc crochet hook portion to become node to fix.
Because the present invention can pass attached to trochantinian muscle gap and introduce steel wire, be convenient to lesser trochanter be resetted by tightening up steel wire, and also simple in structure, be easy to make, but autoclave sterilization.The present invention simple as same piece of pin or crochet hook, the bone surgery instrument that resets as lesser trochanter of femur and prolonged application.
Description of drawings
Fig. 1 is a basic structure sketch map of the present invention.
Fig. 2---Fig. 4 is to use several operating procedure sketch map of the present invention.
Wherein, 1, crochet hook portion, 2, straight-bar, 3, handle portion, 4, the hole, 5, steel wire, 6, femoral head 7, lesser trochanter, 8, node.
The specific embodiment
As Fig. 1, as embodiment, the invention is characterized in: the stage casing of this positor or centre are respectively handle portion 3 and arc crochet hook portion 1 for straight-bar 2, its two ends, and there is the hole 4 that can pass two steel wires at the front tip 5mm place apart from crochet hook portion 1, be that the present invention is made up of the handle portion 3 of crochet hook portion 1, intermediary straight-bar 2 and back segment, there is the hole (steel wire of two diameter 1mm is introduced) of diameter 2mm in crochet hook portion in most advanced and sophisticated nearside 5mm place.Crochet hook portion 1 diameter is 50mm, utilizes its curved portions to wear to the femur rear side, is convenient to that lesser trochanter resets and the introducing of steel wire and fixing.Usually above-mentioned crochet hook portion 1 is that diameter is the arc in the 50mm--60mm scope, to be suitable for the femur of different-diameter.
Manufacture method of the present invention is: the stainless steel bar of at first getting a diameter 4mm, the one end is worn into coniform (the high about 3mm of awl, can pass muscle but do not damage the peripheral vessels nerve), again in the hole of the most advanced and sophisticated nearside 4mm drill diameter 2mm of place (steel wire of two diameter 1mm is introduced), again with this end embowment, and to make arcual diameter be 50mm-60mm, again the straight-bar 2 long 150mm (positor bar) in stage casing, an other end is rectangle or the rhombus handle portion of long 80mm, so that operator grips.Utilize its coniform tip and crochet hook portion to pass and be attached between trochantinian muscle, wear to the lesser trochanter rear side and introduce steel wire, the steel wire two ends are tightened up, assist down lesser trochanter to be resetted and tightens steel wire in arc crochet hook portion to become node to fix;
When the present invention uses, hand-held handle portion 3 is passed lesser trochanter 7 front sides with its tip in Fig. 2, utilizes crochet hook portion 1 to rotate (being close to the femur rear side) backward by its inboard, be threaded to the tip and reveal, in hole 4, penetrate the stainless steel silk 5 of one or two diameter 1mm to lateral side of femur; Again with crochet hook portion 1 along the cycle of former road, steel wire 5 is drawn to the lesser trochanter front side, as Fig. 3; At last steel wire 5 front and back ends are tightened up, assist down lesser trochanter to be resetted and tighten steel wire at positor to become node 8 fixing, as Fig. 4.Obviously, the present invention can be conveniently used in lesser trochanter of femur as the bone surgery instrument and resets.
