Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of Orthopeadic Surgery Kirschner wire inserting needle device.
Background technique
Fracture refers to a kind of disease for causing bone parts due to wound or pathology etc. or being broken completely, in treatment bone
When folding, usually the end that fractures for the bone being displaced after fracture is first restored normal again or close to original normal position, fractured
It after reset, because its is unstable, is easy to happen and shifts again, therefore satisfied position is fixed in using different methods
On, so that it is gradually healed, fixed method has outer fixation and interior fixes two kinds.
Kirschner wire fixation is a kind of method of common interior fixation, and it is solid to generally use Kirschner wire to some unstable fractures
It is fixed, clinically for short bone, irregular bone, close on articular fracture fix and trans-articular it is fixed using Kirschner wire fixation effect compared with
It is good.In fixation Kel's needle, it is necessary first to one end of Kirschner wire is mounted on electric drill, be then turned on electric drill, by kirschner stylus printer
Enter the bone that need to be fixed, but accurately squeeze into the more difficult assurance of Kirschner wire with position by a predetermined angle, especially similar to wrist scaphoid this
The multi-joint face irregular bone of sample needs to extract Kirschner wire, squeezes into again, once when the angles and positions inaccuracy squeezed into
Operation often needs repeatedly to squeeze into, and has virtually aggravated Accessory injury, has further destroyed blood supply, has extended operating time, Jin Erying
Therapeutic effect is rung.The angles and positions for squeezing into Kirschner wire are difficult to grasp, so the once success rate of Kirschner wire fixation operation
It is lower
Therefore, it is necessary to a kind of dress can be positioned to the Kirschner wire that the drilling direction of Kirschner wire is accurately oriented to during surgery
It sets, to effectively improve the success rate of Kirschner wire fixation operation, reduces the operation pain of patient.
Utility model content
The purpose of this utility model be in view of the above shortcomings of the prior art, provide it is a kind of design rationally, structure it is simple, energy
It is enough that the drilling direction of Kirschner wire is accurately oriented to, so as to which Kirschner wire directly to be screwed to the positioning being drilled in advance well
Orthopeadic Surgery Kirschner wire inserting needle device in hole.
To achieve the above object, the utility model is achieved using following technical scheme:
A kind of Orthopeadic Surgery Kirschner wire inserting needle device, including ontology 1, handle 2, reinforcing set 3, inserting needle cover the 4, first fixing sleeve
5, screw set 6, the second fixing sleeve 7, skin gasket 8, fixed jaw 9, locating rod 10 and connecting column 14, it is characterised in that: described
1 one end of body is connect by connecting column 14 with skin gasket 8, and by being threadedly engaged inserting needle set 4 inside ontology 1, inserting needle covers 4 one end
It is fixedly connected with handle 2, the other end left end of inserting needle set 4 is fixedly connected with the first fixing sleeve 5；Second fixing sleeve 7 and rotation
Fixed 6 are cooperated by taper thread, are provided with fastener hole 13 in screw set 5.
The ontology 1 is the cylindrical body of cavity.
Described first fixing sleeve, 5 one end is equipped with circular hole 16, and hole bottom center is equipped with pin holes 12, sets on the outside of circular hole 16
There is rectangular recess 15.
It is equipped with and threads a needle hole 11 in the locating rod 10, and thread a needle hole 11 and pin holes 12 point-blank.
Compared with prior art, the utility model has the beneficial effects that: 1. the utility model is designed reasonablies, structure letter
It is single, easy to use, facilitate the operation of doctor, directly screw Kirschner wire in the hole being drilled in advance, is not necessarily to the hand steered Kirschner wire of doctor,
The pain for mitigating patient, mitigates the operating pressure of doctor；2. the Kirschner wire inserting needle device of the utility model can accurately control into
The position and direction of pin mark, inserting needle position are accurate, it is entirely avoided the displacement of fracture end and the damage threaded a needle repeatedly to tissue, hand
Art one-time success rate is high, can significantly improve the safety of operation and shorten operating time, greatly reduce the operation wind of patient
Danger.
