Description
Technical field
The utility model relates to medical instruments, are specifically related to a kind of bone nail driver.
Background technique
Intramedullary nail is the fracture Medullary fixation for being widely used in four limbs in recent years, and intramedullary nail needs to squeeze into bone during operation
In marrow at folding, then just needing to use bone nail driver, structure is complicated for existing bone nail driver, inconvenient for operation,
The procedure efficiency of medical worker is leveraged, intramedullary nail needs the connector on impactor to pass through screw thread and marrow when squeezing into
The screw hole connection inside nailed on, intramedullary nail is according to of different sizes, and the screw hole size on intramedullary nail is also different, and existing intramedullary nail is beaten
When entering the connector that device replacement matches with screw hole on intramedullary nail, operation is more troublesome, also affects procedure efficiency, for this purpose, I
Propose a kind of bone nail driver.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of bone nail drivers, solve existing intramedullary nail
The problem of structure is complicated for impactor, inconvenient for operation, influences procedure efficiency.
In order to solve the above technical problems, the utility model is the following technical schemes are provided: a kind of bone nail driver, including even
Extension bar, connector, impact hammer and handle, the connecting rod left end is by being threaded with connector, the connector left end one
Equipped with outer stud, it is integrally formed with raised platform on the connector outer wall, is connected with impact hammer on the connection club shaft, institute
The right end for stating connecting rod is fixedly connected with handle.
On the basis of above scheme, the connector is equipped with multiple, the screw thread difference of outer stud on multiple connectors
For different specifications and models.
On the basis of above scheme, the protrusion platform is equipped with multiple, and multiple raised platforms are evenly distributed on connector
On outer wall.
On the basis of above scheme, the impact hammer is slidably matched with connecting rod.
On the basis of above scheme, the outer wall of the handle is equipped with anti-skid chequer.
The utility model has the beneficial effect that a kind of bone nail driver compared with prior art, entire design knot
Structure is simple and clear, and use is swift and convenient to operate, and connector replacement is simple and convenient, does not waste time, substantially increases the effect of operation
Rate, the utility model is simple and reasonable, easy to operate, and low manufacture cost is practical.
Detailed description of the invention
Fig. 1 is a kind of bone nail driver structural schematic diagram of the utility model；
Fig. 2 is a kind of connector left side view of bone nail driver of the utility model.
Figure label are as follows: the outer stud of 1- connecting rod, 2- connector, 201-, 202- protrusion platform, 3- impact hammer, 4- handle,
401- anti-skid chequer.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
In the description of the present invention, it should be understood that term " longitudinal direction ", " transverse direction ", "upper", "lower", " preceding ",
The orientation or positional relationship of the instructions such as " rear ", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" be based on
Orientation or positional relationship shown in the drawings is merely for convenience of description the utility model, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to the utility model
Limitation.
Referring to figs. 1 to known to Fig. 2: a kind of bone nail driver, including connecting rod 1, connector 2, impact hammer 3 and handle 4,
1 left end of connecting rod is integrally formed with outer stud 201, the connection by being threaded with connector 2,2 left end of connector
It is integrally formed with raised platform 202 on first 2 outer wall, impact hammer 3, the right side of the connecting rod 1 are connected on 1 body of rod of connecting rod
End is fixedly connected with handle 4.
The connector 2 be equipped with it is multiple, the screw thread of outer stud 201 is respectively different specification on multiple connectors 2
Model can match the screw hole of various different size models on intramedullary nail convenient for connector 2；It is described protrusion platform 202 be equipped with it is multiple,
Multiple raised platforms 202 are evenly distributed on the outer wall of connector 2, convenient for connector 2 to be quickly screwed into the spiral shell on intramedullary nail
In hole, while being also convenient for the fast quick-detach of connector 2；The impact hammer 3 is slidably matched with connecting rod 1, is connecting convenient for impact hammer 3
It is moved on bar 1；The outer wall of the handle 4 is equipped with anti-skid chequer 401, skidding when preventing from grasping handle 4.
The principles of the present invention and advantage: a kind of bone nail driver, in use, selecting and the screw hole phase on intramedullary nail
The outer stud 201 of connector 2 is screwed into the screw hole on intramedullary nail, then leads to the left end of connecting rod 1 by matched connector 2
It crosses and is threaded on connector 2, a hand steered outer ring for being surely held in handle 4, another hand holds 3 ground outer ring of impact hammer, allows and hit
Hammer 3 moves back and forth in connecting rod 1, and impact hammer 3 does not collide handle 4 when mobile, and connector 2 is hit when impact hammer 3 is mobile,
Under 3 ground impact force of impact hammer, connector 2 drives intramedullary nail to enter in the marrow of fracture by outer stud 201, requires until entering
Depth, connecting rod 1 is backed out from connector 2 then, is back-outed in screw hole from intramedullary nail by connector 2, operation is just
It completes, whole operation process is simple and convenient, and procedure efficiency is high, and the utility model is simple and reasonable, easy to use, cost of manufacture
It is low, it is suitble to promote the use of.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
