Abstract
The utility model relates to a splitting surrounding bone connecting clasp and belongs to an inner fixation bone connecting appliance of medical equipment. The circular arc-shaped surfaces of one end of one half ring bone connecting plate (1) and one end of the other half ring bone connecting plate (2) are provided with saw teeth, and the saw teeth are provided with pin holes. The saw teeth of the half ring bone connecting plate (1) and the half ring bone connecting plate (2) are arranged in the staggered way, and opening ring-shaped structure is formed. A fixing pin (3) penetrates through the pin holes on the saw teeth. The splitting surrounding bone connecting clasp has the advantages that the structure is simple, the operative fixation is convenient, and the splitting surrounding bone connecting clasp can be conveniently taken out and reduce the pain of patients because the surrounding bone connecting clasp is composed of two parts, the pin is drawn when the clasp is taken out and the clasp is divided into two halves.
Description
Technical field
This utility model belongs to medical apparatus and instruments, relates to a kind of utensil of internal fixation synthetism, is a kind of split encircling type synthetism snap ring made from marmem that is used for the tubulose skeleton concretely.
Background technology
The existing multiple patent of the synthetism utensil that utilizes marmem to make is come out.China's utility model patent, the patent No. 97250035.9, Granted publication CN2327330Y, disclosed " encircling bone bonding plate;, be the protruding fixture in both sides of a tabular beam and be rolled into opening ring-type section that this form is fixedly the time; because cooling makes this fixing head deliquescing; be easy to be fixed on the knochenbruch place, but the knochenbruch head restoring is good by the time, take out and recover elastic this fixing head; owing to have no idea to lower the temperature, be a very difficult thing on bone.
Summary of the invention
The purpose of this utility model is exactly to overcome above-mentioned deficiency, and provide a kind of easy for installation, dismounting is easy to the split encircling type synthetism snap ring made with marmem.
The solution that realizes this utility model purpose is to comprise two semi-ring blade plates (1), (2), be sawtooth on the arc surface of an end of two semi-ring blade plates (1), (2) particularly, sawtooth is provided with pin-and-hole, semi-ring blade plate (1) is installed with the sawtooth of semi-ring blade plate (2) is staggered, form an opening circulus, fixator pins (3) is passed the pin-and-hole on the sawtooth.
The centrage of the pin-and-hole on the sawtooth is parallel with the centrage of opening circulus, has two groups of pin-and-holes side by side at least.
The utility model has the advantages that simple in structurely, when fixed installation operation is convenient, because encircling type synthetism snap ring is made up of two parts, extracts pin during taking-up out, and snap ring can take out in two easily, reduces misery to patient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Two semi-ring blade plates 1,2, the arc surface of an end on be sawtooth, semi-ring blade plate 1 is installed with the sawtooth of semi-ring blade plate 2 is staggered, form an opening circulus, parallel with the centrage of the opening circulus pin-and-hole that is provided with on the sawtooth, this pin-and-hole has two groups side by side at least, and fixator pins 3 is installed in the pin-and-hole on the sawtooth.
During the operation synthetism, select circulus diameter dimension of the present utility model to be slightly less than the diameter dimension of tubulose skeleton, and with its cooling deliquescing, cut skin and flesh, the tubulose skeleton that fractures is docked, place this utility model of deliquescing, rising along with temperature, the present invention recovers its original shape, has just fixed the tubulose skeleton that fractures, and sews up then.After knochenbruch recovers, when this utility model is taken out in operation, extract pin out, snap ring can take out in two easily, reduces patient's misery.
Claims (2)
1, a kind of split encircling type synthetism snap ring, comprise two semi-ring blade plates (1), (2), it is characterized in that on the arc surface of an end of two semi-ring blade plates (1), (2) be sawtooth, sawtooth is provided with pin-and-hole, semi-ring blade plate (1) is installed with the sawtooth of semi-ring blade plate (2) is staggered, form an opening circulus, fixator pins (3) is passed the pin-and-hole on the sawtooth.
2, according to the said split encircling type of claim 1 synthetism snap ring, it is characterized in that the centrage of the pin-and-hole on the said sawtooth is parallel with the centrage of opening circulus, have two groups of pin-and-holes side by side at least.
