AI Technical Summary
Technical Problem
Conventional surgical medical instruments with hydraulic cylinders arranged in series along the longitudinal direction result in a relatively large length, making it difficult to navigate through narrow spaces within the body.
Method used
The surgical medical instrument is designed with four pistons arranged in parallel, intersecting the longitudinal direction, allowing the first and second jaw members to rotate around perpendicular axes, reducing the overall length and enabling easier navigation through confined spaces.
Benefits of technology
The parallel piston arrangement shortens the instrument's length, facilitating easier access and operation in narrow bodily spaces by allowing the instrument to curve and bend more effectively.

Abstract
To provide a surgical medical instrument whose length can be shortened.SOLUTION: A surgical medical instrument 100 is so configured that a first piston 31, a second piston 32, a third piston 33 and a fourth piston 34 are disposed side by side in a direction crossing a longitudinal direction of the surgical medical instrument 100. A first jaw member 11 and a second jaw member 12 are rotationally turned about a jaw rotation axis A1 and a wrist rotation axis A2 by the first piston 31, the second piston 32, the third piston 33 and the fourth piston 34.SELECTED DRAWING: Figure 1
