Abstract
The utility model relates to a cable steel sheet for inlaying technology application under an all-arthroscope, which belongs to the technical field of orthopedic surgical instruments. The utility model aims to provide an instrument which is used in a reconstruction surgery of posterior cruciate ligament of knee joints through inlaying technology under the all-arthroscope; and has the technical scheme that: the cable steel sheet comprises a steel sheet, fastening wires and wire clips; the steel sheet is in a rectangular shape; two fastening wires are arranged and are fixed on the steel sheet surface on the same side of the steel sheet, and are respectively fixed on both ends of the steel sheet along a longitudinal shaft of the steel sheet; and the tail ends of the two fastening wires are clamped by the wire clips. The cable steel sheet for inlaying technology application under the all-arthroscope can position and fix tendon bones with the steel sheet and the fastening wires, the 'killerturn' effect of a tibial side in the reconstruction surgery of posterior cruciate ligament of conventional knee joints not only can be eliminated, but also inconvenience caused by fussy surgery operation and incisions behind the knee joints in an ordinary 'inlay' technology can be overcome, the cable steel sheet has the advantages of simple structure, convenience in surgery operation and firmness in fixation, and is a very practical instrument in the reconstruction surgery of posterior cruciate ligament of knee joints.
Description
Technical field
This utility model relates to a kind of cable steel plate that uses in the operation of embedding technique reconstruction posterior cruciate ligament of knee joint under the total joint mirror, belong to the bone surgery set technical field.
Background technology
At present, in the operation of rebuilding posterior cruciate ligament of knee joint, conventional operation method is referred to as the technology of " inlaying " under the total joint mirror, this operation method is at first to prepare allograph bone tendon bone, as heel string bone piece, on tibia, hole then, the tunnel that connects before and after forming, again heel string bone piece is put into the tunnel, sentence the interference screw screw-in at the front edge that heel string bone piece contacts with tibial tunnel, it is fixing to implement extruding, and the tendon that heel string bone piece connects passes from the tibia rear portion, carries out reproducing of posterior cruciate ligament.The shortcoming of this operation is so-called " Killer turn ", it is lethal effect, it is meant because tibial tunnel can only be along the tibia horizontally set, therefore to upwards bend after tendon passes from the tunnel and undergo surgery, the angle of bending is an acute angle, when knee joint seesaws, be easy to the tendon that weares and teares like this, influence the healing of heel string bone piece.In order to change this situation, the doctor who has has taked behind tibia the fixedly method of heel string bone piece, this method is boring placement heel string bone piece on tibia no longer, but heel string bone piece is screwed at the tibia trailing edge, tendon on the heel string bone piece just upwards directly carries out reconstructive operation like this, and need not bend.But this method still has certain shortcoming, at first, cut the skin at knee joint rear portion and fix, and has increased the otch of operation; Secondly, there are more nerve and blood vessel in the knee joint rear portion, sustains damage easily; Also have, carry out the operation of knee joint posterior incision and the patient need be stood up, this can increase the chance of polluting in the operation.In view of all there is certain shortcoming in above-mentioned operation, be necessary to improve to rebuilding the posterior cruciate ligament of knee joint operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, operation technique convenience, fixation, the tendon that can not wear and tear, need not increase the cable steel plate that embedding technique is used under the total joint mirror of otch at the knee joint rear.
The technical scheme that solves the problems of the technologies described above is:
The cable steel plate that embedding technique is used under a kind of total joint mirror, it is made up of steel plate, fastening line, ply-yarn drill, steel plate is a rectangle, fastening line is two, fastening line is fixed on the steel plate face of steel plate the same side, respectively at the two ends that are fixed on steel plate, the end of two fastening lines is tightened by ply-yarn drill along the longitudinal axis of steel plate.
The cable steel plate that embedding technique is used under the above-mentioned total joint mirror, described steel plate are that titanium alloy is made, and the radian of bending is arranged along the Y-direction both sides of steel plate, and the length of steel plate is 5-10mm, and width is 1.5-3mm.
The cable steel plate that embedding technique is used under the above-mentioned total joint mirror, described fastening line is titanium alloy line or steel wire, diameter is 0.5-0.7mm, and the fixing point of two fastening lines is along steel plate longitudinal axis distance each 1-1.2mm place, upper and lower edge, and the distance between two fastening lines is 2.5-8mm.
The cable steel plate that embedding technique is used under the above-mentioned total joint mirror, described ply-yarn drill is the metallic cylinder of hollow, and the length of metallic cylinder is 2-2.5mm, and interior diameter is 1.5-2mm.
This utility model can locate heel string bone piece, fix with steel plate and fastening line, can eliminate " Killer turn " effect of tibial side in the conventional posterior cruciate ligament of knee joint reconstruction operations, can overcome the inconvenience that operation technique is loaded down with trivial details and knee joint rear otch brings that common " Inlay " technology is brought again, have that simple in structure, operation technique is convenient, the advantage of fixation, be to rebuild a kind of apparatus very practical in the posterior cruciate ligament of knee joint operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is user mode figure of the present utility model.
Number in the figure is as follows: steel plate 1, fastening line 2, ply-yarn drill 3, heel string bone piece 4, tibia 5.
The specific embodiment
Show among the figure that this utility model is made up of steel plate 1, fastening line 2, ply-yarn drill 3.
Steel plate 1 is that titanium alloy makes, and hardness and resistance to compression, resistance to tension are strong.There is crooked radian Y-direction both sides along steel plate 1, and the length of steel plate 1 is 5-10mm, and width is 1.5-3mm.The one side of steel plate 1 is a shiny surface, and another side connects fastening line 2.
Fastening line 2 is titanium alloy line or steel wire, and extremely strong tension stress is arranged, and diameter is 0.5-0.7mm.Two fastening lines 2 are fixed on the same side of steel plate 1, and fixing point is along steel plate 1 longitudinal axis distance each 1-1.2mm place, upper and lower edge, and the distance between two fastening lines 2 is 2.5-8mm.
