Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The steel plate is the most commonly used internal fixation instrument, and for proper fracture, the steel plate must have enough width and thickness, the steel plate must have certain symmetry, so that both ends of the fracture can be fixed, the steel plate must be in close contact with the bone, and in addition, the steel plate must be capable of neutralizing acting force of multiple parties.

For the steel plate close to the joint part, because the functional requirement on the joint is high, the remained foreign matters sometimes become the chief culprit of influencing the joint movement, such as the clavicle hook steel plate at the acromioclavicular joint part, the screw at the ankle part, the kirschner wire at the finger or the metacarpal bone, and the like, if the foreign matters are not taken out, the joint movement can be influenced, and in some special parts of the body, such as crus with thin skin and clavicles of beauty-loving women, the steel plate is easy to touch, so that the skin is uncomfortable to touch, and on the other hand, the skin is easy to be damaged by repeated friction between the steel plate and the skin, and even the skin can be damaged. In these cases, it may be more advantageous to take out the steel plate itself.

On one hand, the steel plate can be gradually fused with human tissues along with the lapse of time, and part of soft tissues usually exist on the steel plate, such as synovial capsule, nerve, tiny blood vessel and the like.

Therefore, the utility model provides a locking steel sheet separator, refer to fig. 1, including last cutting blade 1 and lower cutting blade 2, the top of going up cutting blade 1 and lower cutting blade 2 that goes up cutting blade 1 and lower cutting blade 2 relative setting sets up cutting portion 3, goes up to be provided with on cutting blade 1 and makes to go up cutting blade 1 and lower cutting blade 2 and take place relative displacement's locking mechanism 4, is provided with supplementary cutting blade 7 on the lower cutting blade 2.

Further, in the utility model discloses in, refer to fig. 2, go up cut 1 and cut 2 and be used for the cutting to cover the soft tissue on surface down, but because the steel sheet generally is type of cube, have the crossing right angle in two sides, consequently, to the software tissue of here, the utility model discloses additionally designed supplementary cut 7, supplementary cut 7 perpendicular to go up cut 1 and cut 2 down to make supplementary cut 7 and last cut 1 and cut 2 and form a right angle down, correspond this right angle with the right angle of steel sheet, thereby the accurate soft tissue of cutting right angle department.

Further, the utility model discloses in, because the cross-sectional area of steel sheet is not very huge, consequently the utility model discloses a too huge that whole volume is not suitable for is not done, for this reason for the current volume of make full use of, reaches the purpose in make full use of space, compromises medical personnel's use simultaneously and feels, lower cutting blade 2 on be provided with the parcel limit 21 that will go up cutting blade 1 parcel, supplementary cutting blade 7 is installed on parcel limit 21, with the integrative setting in parcel limit 21, and as shown in the figure, go up cutting blade 1 and surrounded the parcel by cutting blade 2 down, have concurrently and feel and the volume.

Further, the utility model discloses in, go up the cutting blade 1 and include first stratum 11 and second stratum 12, first stratum 11 and second stratum 12 adopt smooth transition, first stratum 11 surface sets up locking device, second stratum 12 surface sets up buffering

arch

5, 1 surface of last cutting blade set up buffering arch 5, buffering arch 5 includes main buffering arch 5 and vice buffering arch 5, stripping off the in-process of buffering tissue and steel sheet, adopts the cutting blade to hug closely the steel sheet to peel off the soft tissue in addition the mode of flat push, if the surface of cutting blade is too smooth, can have the situation emergence that the piece surface was tightly cut to partial soft tissue, consequently for alleviating this type of phenomenon, buffering arch 5 separates certain distance with soft tissue and cutting blade surface to adhesion phenomenon can not take place.

Furthermore, in order to enhance the separation function, a buffer strip 51 is arranged between the buffer bulge 5 and the cutting part 3 for the relatively short or slight soft tissue such as capillary, and the buffer strip 51 is arranged in parallel with the cutting part 3.
