Description

Orthopaedics special-purpose taking nail bit head

Technical field

The utility model relates to a kind of orthopaedics special-purpose taking nail bit heads.

Background technique

Currently, the method for operation implant plate can be taken to fix the bone fracture to fracture for fracture patient, steel plate needs to use Steel nail is fixed, and is to be threadedly coupled between steel plate and steel nail.

But nail is different, when taking nail, needs to be prepared according to the type of nail different to take nail tool, switching It is more troublesome, delays operating time.

Based on the above issues, it is desirable to provide the orthopaedics for taking nail to need that one kind can meet nail of different shapes simultaneously is special With taking nail bit head.

Utility model content

The technical problem to be solved by the utility model is to provide one kind can meet taking for nail of different shapes simultaneously Follow closely the orthopaedics special-purpose taking nail bit head needed.

The utility model is achieved through the following technical solutions:

A kind of orthopaedics special-purpose taking nail bit head, including casing, and cooperation at described sleeve pipe right positions, be used to support it is described The bracket of sleeve rotating is provided with a through-hole at the outer wall position of described sleeve pipe, which extends radially through described sleeve pipe, described A groove body is provided on the left of bracket, described sleeve pipe cooperates in the groove body, is arranged at the two sides cell wall position of the groove body There is the rotary shaft being embedded in the through-hole, is internally provided with a baffle in described sleeve pipe, is evenly equipped in the plate face of the baffle Second through-hole, has assigned force application rod in second through-hole, and the right end of the force application rod has limit head, the spacing head The diameter in portion is greater than the aperture of the through-hole, a piston part is connected in the internal whorl of described sleeve pipe, in the inside of described sleeve pipe It is provided with a spring, is internally provided with limit in the first baffle of the limit right side of head, the spring in described sleeve pipe Cooperation is between the first baffle and the piston part, and there are two ends for annular setting at the outer wall position of the bracket, leads to It crosses the end thread and is connected with handlebar stem.

Preferably, the right side of the piston part has the head for the polygon for facilitating driving, in the right end position of the bracket The place of setting offers first through hole, and adjustable pipe is combined in the first through hole, and the left end of the adjustable pipe has described in cooperation The force set on head is provided with the polygon force part of cooperation spanner at the right end position of the adjustable pipe, logical When crossing handlebar stem runing rest and carrying out drive sleeve rotation, adjustable pipe can be inserted into, so that force set engagement head, casing at this time Locking is realized between bracket, casing is non-rotatable, when the required nail construction removed is more firm, can with runing rest, So that the arm of force extends, adjustable pipe can be pulled out to that one end far from head at this time, so that the arm of force is further elongated, just In the enough rotation torques of offer.

Preferably, the handlebar stem has spherical limited block far from that one end of the end.

Preferably, the force application rod is solid hopkinson bar, and the diameter of the force application rod is 0.2mm-0.45mm, the force application rod with The limit head is an integral structure.

The beneficial effects of the utility model are: the present apparatus is in the state of unused, by piston part limit spring, spring to First baffle is resisted after outer pop-up, first baffle is pushed up to the left, force application rod extends to extreme position to the left at this time, is taking When nail, by casing alignment nail insertion, force application rod moves to the right under the barrier force effect of nail at this time, and is not made by nail The force application rod of power remains stationary, at this point, revoling tube, force application rod can block nail, and satisfaction takes nail needs, can satisfy difference The nail of model takes nail needs to avoid the trouble of diverter tool without preparing multiple types of tools, and the structure of the present apparatus is relatively simple, Cost is more cheap, is suitble to promote the use of.
