Description
Technical Field
The utility model relates to the technical field of medical equipment, especially, relate to a finger fracture reduction fixation device that easy operation, damage are less.
Background
Because of the increasing frequency of human activities, the fracture patient that various reasons caused also increases year by year, generally adopts external fixation treatment to the fracture at present, for example splint ligature is fixed and the gypsum is fixed, to finger fracture, then can adopt one or more little splint centre gripping, is equipped with bandage or ribbon and bindes, causes the operation complicacy, and little splint are easy to shift, and ligature dynamics and direction can not be controlled in addition, probably produces the secondary damage, also does not benefit to the blood circulation of finger portion, extension healing time.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the defects of the prior art and provides a finger fracture reduction fixing device with simple operation and less damage.
In order to solve the technical problem, the utility model mainly adopts the following technical proposal:
the utility model discloses a finger fracture fixing device that resets for finger after the fracture resets and fixes, the device includes the tubulose shell, and the shell inner chamber inlays and is equipped with a tubulose gasbag, gasbag and shell internal diameter coincide mutually and laminating shell inner chamber, gasbag internal diameter and above-mentioned finger coincide and the cover locate on the finger, be equipped with air bag joint on the gasbag, the outside mechanism of qi of air bag articulate adopts the fixed finger skeleton of gasbag, can adjust the gasbag as required and press and control the gasbag extrusion force in the gasbag, and it is fixed to satisfy not finger fracture of equidimension, and device simple structure, the operation is swift effective, and healing stability is good.
Preferably, the air bag joint is a quick joint for air, so that the air pipe of an external air machine can be removed, the internal pressure of the air bag is kept, and the finger bone fixation and healing for a long time period are adapted.
Preferably, the head of the shell is closed, the bottom of the shell is open, a through hole is formed in the wall surface of the middle of the shell and is matched with the air bag connector, and the air bag connector penetrates through the through hole and is connected with an external air engine.
Preferably, the head part of the shell is of a hemispherical structure, the center of the head part of the shell is provided with a kirschner wire guide hole, the kirschner wire guide hole is matched with the kirschner wire in diameter and accommodates the kirschner wire, and the kirschner wire can be accurately driven into a finger bone through the kirschner wire guide hole on the head part of the shell to connect, fix and fuse the fractured finger bone.
The utility model has the advantages that: adopt the fixed finger skeleton of gasbag, can adjust gasbag internal pressure as required and control the gasbag extrusion force, it is fixed to satisfy the finger fracture of equidimension not, and device simple structure, the operation is swift effective, and healing stability is good, and the ke needle bullport at shell top makes things convenient for the accurate needle insertion of ke shi needle again, reaches the good restoration and the healing of finger skeleton.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a shell, 2 is an air bag, 3 is an air bag joint, and 4 is a kirschner guide hole.
Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.
Example (b): the finger fracture reduction fixing device of the embodiment is used for finger reduction and fixation after fracture, as shown in fig. 1, the reduction fixing device comprises a tubular shell 1 with equal diameter, the head of the shell is of a hemispherical closed structure, the bottom of the shell is of an open shape, a through hole is designed on the wall surface of the middle part of the shell, a tubular air bag 2 is embedded in the inner cavity of the shell, the outer diameter of the air bag is matched with the inner cavity of the shell and is attached to the inner cavity of the shell, the inner diameter of the air bag is matched with the fingers and can be sleeved on the fingers, an air bag connector 3 is designed on the air bag, the air bag connector is a quick connector for air and is matched with the through hole, the air bag connector penetrates through the through hole to be connected with an external air engine, a kirschner wire guide hole 4 is designed in the center of the head of the.
When the device is used, the uninflated resetting fixing device is sleeved on a finger, the finger is inserted into the air bag, then an air pipe of an external air engine is inserted into the air bag connector, the air engine is started, the air pressure is adjusted according to needs, at the moment, the air of the air engine is injected into the air bag, the surface of the inflated air bag is enclosed and extrudes the finger, the reliable fixation of the finger is ensured, if the kirschner wire is needed to connect and repair the finger skeleton, the kirschner wire can be accurately guided to be driven into the finger skeleton through the kirschner wire guide hole at the head of the shell, the air engine is closed after the repair and fixation is completed, the air pipe of the air engine is disassembled, at the moment, the air bag connector is quickly closed, the air pressure in the air bag is kept stable and continuously extrudes the finger, the fractured finger can maintain the fracture alignment under the protection of the resetting fixing device, the air bag retracts and is separated from the fingers, and the exiting process is finished.
In the description of the present invention, the technical terms "upper", "lower", "front", "rear", "left", "right", "longitudinal", "horizontal", "inner", "outer" and the like indicate the direction or the position relationship based on the direction or the position relationship shown in the drawings, and the technical solution of the present invention is only for the convenience of description and understanding, and the above description is not limiting to the present invention, the present invention is not limited to the above description, and the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the present invention should be regarded as the protection scope of the present invention.
