Description
Technical field
This utility model relates to a kind of expandable nail spanner with gimbal suspension, belongs to medical instruments field, is particularly useful in bone surgery.
Background technology
Spanner is a kind of conventional installation and removal instrument, utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware, spanner is conventionally shaped with clamp holder portion in the one or both ends of shank and applies external force, just can twist bolt or nut and hold opening or the trepanning of bolt or nut.When use, apply external force along screw thread rotation direction at shank, just can twist bolt or nut.
The spanner in medical device industry field is varied, has fork spanner, box spanner, and combination wrenches, double offset ring spanner etc., double offset ring spanner two ends have the working end with hexagon ring or 12 jiaos of holes, are applicable to work space narrow and small, can not be suitable for the occasion of common wrench.Single for the spanner design of expandable nail at present, our company has gone out a kind of novel expandable nail spanner through research and development department's development and design.
Summary of the invention
The purpose of this utility model is: a kind of expandable nail spanner with gimbal suspension is provided.
The technical solution of the utility model is as follows:
This utility model is made up of universal wrench head (1), block (2), bearing pin (3), torque handle (4), it is characterized in that: universal wrench head (1) is made up of wrenching bar (5), joint coupling (6), bearing pin (3), spring (7) and handle and connecting rod (8); Torque handle (4) is made up of bearing pin (3), inner clutch (9), outer end clutch (10), spring (11), screw (12), hand holding handle (13) and handle plug (14).
Wrenching bar (5) left end is outer six sides, and head is spherical, the conical surface arc transition of six side's right-hand members and wrenching bar, when this project organization advantage is operation technique, spanner can be easily and interior six boat nail sub-connections, and reduce significantly the probability that spanner in use fractures because of the ambassador's spanner of exerting oneself.Right-hand member has step, and step right-hand member is a square structure, and has through hole and groove, is connected with joint coupling and bearing pin (3), realizes the universal adjustment of expandable nail spanner.
Handle and connecting rod (8) is such with the structure of joint coupling (6) junction: have step, step right-hand member is a square structure, and there are through hole and groove, be connected with joint coupling (6) and bearing pin (3), realize the universal adjustment of expandable nail spanner.
The utlity model has following advantage:
Basis is practical is that handle has limit torsion function, can realize the limit torsion of 1N.m.
This practical gimbal suspension structural design that is, joint coupling (6) can be realized 360 ° of spinfunctions in 45 ° of circumference range, torque of wrenches is played to the effect of buffering, thereby has avoided the fracture of spanner six square toes portions.
This practical spring (7) that is gimbal suspension place, can ensure wrenching bar (5) natural resilience after rotating.
This utility model is that wrenching bar (5) can bear the above torsion of 2～2.5N.m and can not break, and safety gets a promotion, and when without gimbal suspension, can bear 1.2～1.5N.m torsion.
This utility model is in the time of operation technique, simple to operate, practical.

Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is driving end of the present utility model (1) structural representation.
Fig. 3 is torque handle of the present utility model (4) structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
This utility model is made up of universal wrench head (1), block (2), bearing pin (3), torque handle (4), the arrow points of Fig. 1 is the activity direction of wrenching bar (5), when use, hand-held torque handle (4), wrenching bar (5) is screwed in screw hexagonal hole, adjust the anglec of rotation of driving end (1), adjust its radially with the position of longitudinal direction, rotate torque handle (4) and expandable nail is adjusted to operation needs state.
