Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
The utility model relates to a pair of novel surgical scissors, which comprises a fixed cutter body and a movable cutter body which are in pin joint fit.
The fixed cutter body comprises a fixed cutting edge 1, a fixed connecting rod 2 and a sleeve 3; the fixed blade 1 and the sleeve 3 are respectively connected to two ends of the fixed connecting rod 2, and the fixed blade 1 and the fixed connecting rod 2 form an included angle of less than 180 degrees;
the movable cutter body comprises a movable cutting edge 4 pivoted with the fixed cutting edge 1, a movable connecting rod 5 arranged in parallel with the fixed connecting rod 2 and a bending elastic piece 6; the movable blade 4 is connected with one end of the movable connecting rod 5 through a section of memory metal 7, and forms an included angle smaller than 180 degrees; the movable connecting rod 5 is arranged in the sleeve 3 in a penetrating way; two ends of the bending elastic piece 6 are respectively connected with the other end of the movable connecting rod 5 and the sleeve 3;
when the bending elastic piece 6 is pressed towards the movable connecting rod 5, the movable connecting rod 5 is driven to move in the sleeve 3, and the movable blade 4 is driven to be closed with the fixed blade 1 to complete the shearing action.
When the utility model is implemented, the structure is further as follows:
the bending elastic piece 6 is a metal elastic piece bent into an arc shape so as to ensure that the bending elastic piece 6 has stronger elasticity to restore the original shape, and the service life of the utility model is prolonged. Furthermore, the connection between the bending elastic part 6 and the movable connecting rod 5 is in pivot joint fit, and the end parts of the bending elastic part and the movable connecting rod can rotate relatively, so that the connection between the bending elastic part 6 and the movable connecting rod can rotate to reduce the angle when the bending elastic part is compressed, the excessive resistance on the hand of a user is avoided, and the operation is more convenient.
The fixed blade 1 is connected to the end of the fixed connecting rod 2 through a section of memory metal 7', so that the relative angle between the fixed blade 1 and the fixed connecting rod 2 can be adjusted to adapt to different use environments, and meanwhile, the fixed blade can be correspondingly deformed along with the opening or closing action of the movable blade 4 and the fixed blade 1, so that the smoothness of the shearing action is improved.
The memory metal 7 can be matched with the angles of the fixed blade 1 and the fixed connecting rod 2 and the angles of the movable blade 4 and the movable connecting rod 5 for bending.
Referring to fig. 1, a first embodiment of the present invention is shown.
The fixed cutter body also comprises a handle 8, the handle 8 is connected with the sleeve 3, and a user can conveniently position the sleeve 3 by fingers and perform the opening and closing operation of the scissors.
Referring to fig. 2, the working principle of the first embodiment is as follows: when the fixed blade 1 and the movable blade 4 are in proper positions, a user can insert fingers (such as an index finger and a middle finger) into the grip 8 and hold the same, meanwhile, other fingers (such as a thumb) of the same hand press the bending elastic piece 6 to deform the bending elastic piece 6, the bending elastic piece 6 drives the movable connecting rod 5 to move along the axis direction of the fixed connecting rod 2 (rightwards in the figure), and the movable connecting rod 5 drives the movable blade 4 to rotate by taking the pin joint of the movable blade 4 and the fixed blade 1 as an axis, so that the movable blade 4 and the fixed blade 1 are closed, and the shearing action is completed.
Referring to fig. 3, a second embodiment of the present invention is shown.
The bending elastic member 6 is arranged on the same side of the sleeve 3 with the fixed blade 1 and the movable blade 4, so that a user can hold the sleeve by a palm and tightly hold the elastic member 6 by fingers to deform the elastic member when shearing, thereby closing the fixed blade 1 and the movable blade 4.
Through the scheme, the fixed cutting edge 1 and the fixed connecting rod 2, the movable cutting edge 4 and the movable connecting rod 5 which form included angles with each other are arranged, the movable connecting rod 5 is driven to move in the sleeve 3 by the deformation of the bending elastic piece 6 driven by external force, and the fixed cutting edge 1 and the movable cutting edge 4 are opened or closed to finish shearing action, and a user can finish the action by using one hand.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
