The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel torque handle, including housing Pipe and six square bars, six square bars are mounted in outer tube, and the tail end of outer tube is limit base, are connected in limit base by bushing and handle It connects, handle end screws in screw, and screw is connect with the thread groove of six square bar tail ends.

Another embodiment according to the present utility model further comprises that silica gel sheath is cased on handle.

Another embodiment according to the present utility model further comprises, fluted on limit base, extend on handle Pointer in groove.

Another embodiment according to the present utility model further comprises having graduation apparatus on limit base.

The utility model has the beneficial effects that this novel torque handle reaches required torsion by torsional deflection Value, the design of T-type structure makes doctor, and sight will not be affected in the course of surgery, be conducive to operation go on smoothly and Structure is simple, easy to use, and torque value range is 12N.m ± 1, and torque value is reliable and stable, and key position possesses optimal intensity And fracture toughness, meet the clinical requirement reused.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the handle arrangement schematic diagram of the utility model；

Fig. 3 is the partial enlargement diagram of Fig. 1 of the utility model；

1, six square bar in figure, 2, outer tube, 3, limit base, 4, handle, 5, silica gel sheath, 6, bushing, 7, screw, 8, groove, 9, pointer, 10, graduation apparatus.

Specific embodiment

If Fig. 1 is the structural schematic diagram of the utility model, a kind of novel torque handle, including outer tube 2 and six square bars 1, Six square bars 1 are mounted in outer tube 2, characterized in that the tail end of outer tube 2 is limit base 3, passes through bushing 6 and hand in limit base 3 Handle 4 connects, and 4 end of handle screws in screw 7, and screw 7 is connect with the thread groove of six square bars, 1 tail end.

The position as shown of six square bar 1 is packed into handle 4, outer tube 2 is assembled with limit base 3 and is swashed in interface Photocoagulation one week, bushing 6 is packed on limit base 3, the limit base 3 assembled is packed into six square bars 1 from left side, it will be on handle 4 Boss work good with the groove on limit base 3, calibrate and be arranged torque value, screw 7 is screwed into the internal screw thread of six square bars, 1 right end In, the gap between limit base 3 and handle 4 is adjusted by adjusting the depth that screw 7 is screwed into, in screw 7 after screw thread is tightened Argon arc welding is carried out with 4 junction of handle, since six square bars 1 itself have certain toughness, is fixing limit base 3 and handle After gap between 4, the torsion that six square bars 1 reverse when in use just can determine that, realize the purpose for limiting torsion.

Another embodiment according to the present utility model further comprises that silica gel sheath 5 is cased on handle 4.

The silica gel sheath 5 being cased on handle 4 facilitates doctor to hold, and satisfies the use demand.

When in use, the inner core of silica gel sheath 5 and handle 4 are assembled for this novel torque handle, junction argon Arc welding.

Another embodiment according to the present utility model further comprises, fluted 8 on limit base 3, has on handle 4 and stretches Enter to the pointer 9 in groove 8.

Another embodiment according to the present utility model further comprises having graduation apparatus 10 on limit base 3.

During use, the head interface of six square bars 1 carries out rotation silica gel sheath 5 with the cooperation of corresponding implantation material, will Implantation material is tentatively locked, and when needing finally to tighten implantation material, silica gel sheath 5 continues to rotate, and utilizes the bar at the intermediate position of six square bar 1 Body elasticity deformation, 9 position of pointer can correspond to the corresponding graduation apparatus 10 in bottom from fractional value to big numerical value at this time, if observation numerical value does not reach To target value, need to continue to rotate handle piece 5 until 9 scale value of part reaches target torque value.

It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait Effect, but all will fall within the protection scope of the utility model.
