Abstract
An easily-detachable memory alloy connector comprises a semi-circular left plate and a semi-circular right plate. Connecting holes are formed in the left plate, and snap rings are arranged on the right plate corresponding to the connecting holes. According to the easily-detachable memory alloy connector, the left plate and the right plate are made of memory alloy, by the adoption of the characteristics of the memory alloy, the easily-detachable memory alloy connector can be conveniently installed at a wounded part and easily detached, and in the processes of installation and detaching, pains brought for a patient can be effectively relieved.
Description
Technical field
This utility model relates to medical instruments field, specifically is a kind of easy-dismount memorial alloy bone fracture device.
Background technology
At present, when doing the tubular bone fracture operation, arrangement adopts stainless steel silk, intramedullary needle, steel plate or synthetic resin to fix after suffering from bone usually.During fixation with steel wire, the too pine of binding does not have a fixing effect, and binding too tight influence the blood confession of periosteum, cause serious adverse consequences such as malunion of fracture, healing delay, and after the union of fracture, steel wire also is difficult for taking-up.Steel plate is fixing more firm, but needs boring, pedicle screw, and operation is complicated, and operating time is long, and cell reaction takes place easily; But absorbable material has absorption characteristics, does not need second operation to get fixture, but its fixed effect is not firm, insufficient strength.Above-mentioned operating difficulty is all bigger, and not easy to operate, operating time is longer; Therefore, these tubular bone fixing meanss have certain risk, and fixed effect is not good.Though Chinese patent 03134358.9 disclosed twin beams or three beam encircling bone bonding plates have solved the fixation problem of tubular bone fracture, operation technique is simple, shortened operating time, but complexity when taking out, need the cooling blade plate after 4 ~ 5 minutes, break 10 one by one into two with one's hands with special vice and fork-shaped ripping bar and encircle arm, not only take out the mode complexity, take-off time is longer, brings bigger misery to the patient.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of installation and removal, a kind of easy-dismount memorial alloy bone fracture device simple in structure of being easy to.
This utility model solves its technical problem by the following technical solutions.
A kind of easy-dismount memorial alloy bone fracture device comprises left plate and the right panel of semi-annular shape, and described left plate is provided with connecting hole, and described right panel is provided with the clasp corresponding with described connecting hole.
The quantity of described connecting hole is 1 ~ 10; The quantity of described clasp is 1 ~ 10.
Described left plate is connected by securing member with right panel.
A kind of easy-dismount memorial alloy bone fracture device that this utility model provides, left side plate, the equal practical memorial alloy of right panel are made, utilize the characteristic of memory alloy material can make things convenient for toward the affected part installation, but and easy removal, the misery of in the installation and removal process, bringing to the patient can effectively be alleviated.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is left plate structure sketch map;
Fig. 3 is the right panel structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of easy-dismount memorial alloy bone fracture device comprises the left plate 1 and right panel 3 of semi-annular shape, has connecting hole 2 on the left plate 1, and the clasp 4 corresponding with connecting hole 2 arranged on the described right panel 3.The quantity of connecting hole 2 is 1 ~ 10; The quantity of clasp 4 is 1 ~ 10, and is corresponding with the quantity of connecting hole 2.Left side plate 1 can reinforce the connection by securing member 5 with right panel 3.
This utility model is a kind of easy-dismount memory bone connector, adopts shape memory alloy material to make, moulding in 0 ~ 5 ° of C brine ice after, implant and suffer from bone, can hold tightly behind the deformation recovery and suffer from bone and realize continuing the self-pressurization function, the tight contact of the seam that more is conducive to fracture makes fixed; Utilize the memory characteristic of memory alloy material, after the clasp 4 of right panel 3 penetrated the connecting hole 2 of left plate 1, shape was recovered left plate persistent pressure, had played the effect that connects left and right sides plate; Two plates about adopting securing member 5 to reinforce the connection are fitted closely left and right sides plate, and have strengthened stability, the safety of bone fracture device.Only need incised tissue after the union of fracture, unload securing member 5, cold compress and stretching clasp 4 can easily be taken left and right sides plate apart, skeleton are not caused the secondary injury.The manufactured materials of a kind of easy-dismount memory bone connector of the present utility model is selected the material that has the temperature memory function in the prior art, has excellent biological compatibility simultaneously for use, as Ti-Ni marmem, extensive use in clinical, safe, nontoxic, nothing rejection in vivo.With the easy-dismount memorial alloy bone fracture device of board making, art shapes is simple, and stable, safety are installed in easily deformable installation after the complex, and is convenient quick during taking-up.The structure of hollow out in the middle of adopting, bone fracture device is that point contacts with skeleton, is conducive to the blood confession of bone surface, and fracture is healed as early as possible.Easy to use in operation, do not need boring, can reduce intraoperative hemorrhage and to the damage of osseous tissue, simplify operation technique, shorten operating time, thereby alleviated patient's misery.
