The top surface of the lower shear blade can be additionally provided with an inclined blade, the inclined blade is fixedly connected with the top surface of the lower shear blade, the left side of the inclined blade is edged, the right side of the inclined blade is a vertical surface, and the vertical surface and the upper shear blade are arranged in the same plane.

Left side scissors arbor and right scissors arbor can be left side straight scissors arbor and right straight scissors arbor, left side straight scissors arbor and right straight scissors arbor are the straight body of rod, its front end respectively with the root fixed connection of last scissors sword and lower scissors sword, its root fixedly connected with ring.

Further, left side scissors pole and right side scissors pole can be left side bending scissors pole and right side bending scissors pole, left side bending scissors pole and right side bending scissors pole are the body of rod of bending, its front end respectively with last scissors sword and the root fixed connection of lower scissors sword, the contained angle more than or equal to between its front end body of rod and the scissors sword 90 is less than 180, its root fixedly connected with ring.

The utility model has the advantages that: the problem of cut the easy damage of membrane nature tissue operation and touch the tissue is solved, a membrane nature tissue operation scissors is provided, the smooth no edges and corners in lower limb front end and bottom surface can be picked up membrane nature structure, increase the distance between membrane nature structure and the below tissue to play the guide effect, make things convenient for the operation, when cutting the operation, the tissue is not damaged under the protection film, can be accurate effectual cut membrane nature tissue, reduce the operation degree of difficulty, accomplish minimal access surgery operation.

Detailed Description

As shown in fig. 1-8, a pair of membranous tissue surgical scissors comprises a left scissor bar, a right scissor bar, a hinge shaft 1, a lower scissor blade 4 and an upper scissor blade 5, wherein the upper scissor blade 5 is cross-hinged with the lower scissor blade 4 through the hinge shaft 1, the root of the upper scissor blade 5 is fixedly connected with the right scissor bar, the root of the lower scissor blade 4 is fixedly connected with the left scissor bar, and the root parts of the upper scissor bar and the lower scissor bar are provided with finger rings. The upper shear blade 5 has a right side edge, a left side surface, a lower shear blade 4, an arc-shaped plate body, a left side wall and a right side wall, a bottom surface and a front end surface are both arc surfaces, and the left vertical surface of the upper shear blade 5 and the right vertical surface of the lower shear blade 4 are in the same plane.

The top surface of the lower shear blade 4 can be additionally provided with an inclined blade which is fixedly connected with the top surface of the lower shear blade 4, the left side of the inclined blade is edged, the right side of the inclined blade is a vertical surface, and the vertical surface and the upper shear blade 5 are arranged in the same plane.
