The subtalar joint tensor adopts kirschner wires, can reduce the injury to the subtalar joint, and can also be applied to reduction and temporary fixation of limb fractures with broken ends overlapping and dislocating.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of subtalar joint dilator.
Background technology
Retractor claims again drag hook, in order to retract tissue, appears operating field, is convenient to detect and operate, and can be divided into hand-held drag hook and self-retractor two classes.For articular surface fracture of calcaneus, during operation, need observe the reset case of articular surface.But because subtalar joint joint space is less, difficult exposure, affects complete observation articular surface reset case, therefore need to when operation, need to adopt retractor.Existing retractor while performing the operation for subtalar joint, adopts screw to retract, and because screw is thicker, when inserting subtalar joint, may cause damaging articular cavity.
Utility model content
This utility model provides a kind of subtalar joint dilator, solves the problem that existing subtalar joint dilator easily damages articular cavity.
The technical solution of the utility model is such realization:
A subtalar joint dilator, comprises tooth bar, is provided with fixed cover and can be along the sliding sleeve of tooth bar relative sliding on tooth bar, and fixed cover is fixedly installed on tooth bar one end, and fixed cover is connected with fixation Kel's needle device, connection activity Kirschner wire device on sliding sleeve.
Wherein, preferably, fixation Kel's needle device comprises locking pin sleeve pipe and fixation Kel's needle, and locking pin sleeve pipe one end is connected with fixed cover, and the locking pin sleeve pipe other end is used for placing fixation Kel's needle.
Wherein, preferably, movable Kirschner wire device comprises active pointer sleeve pipe, movable Kirschner wire and gear, and active pointer sleeve pipe one end is connected with sliding sleeve, and the active pointer sleeve pipe other end is used for placing fixation Kel's needle, and wheel and rack is meshed, and is fixed on sliding sleeve.
Wherein, preferably, fixation Kel's needle and movable Kirschner wire are at grade.
Wherein, preferably, movable Kirschner wire device also comprises gripping mechanism.
Wherein, preferably, gripping mechanism comprises open-work, card article and is fixedly installed on the spring on sliding sleeve, open-work is arranged on sliding sleeve, card article is movably connected on sliding sleeve by arm pin, and one end of card article can be used for clamping sliding sleeve through open-work, and the other end of card article is connected with spring.
The utlity model has following beneficial effect:
This utility model is used Kirschner wire instead, the internal fixation material that a kind of orthopaedics of Kirschner wire is conventional, and its specification is generally fixed on 20cm left and right, and diameter has different several specifications between 0.5-2mm.For fixing short and small fracture or the little fracture fixation of avulsion fracture iso-stress, be also often used in interim sclerite in bone surgery fixing.Because Kirschner wire diameter is less, therefore can alleviate damage, the extremity fracture that this utility model also can be applied to the overlapping displacement of the broken ends of fractured bone resets and is temporary fixed.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
