A shock-absorbing mechanism includes a shaft having a linear member wound therearound, a base having a relative position fixed to a first end of the linear member and formed with a shock-absorbing space which spreads toward the radial outside from the outer peripheral surface of the shaft, and a passage formed in the base in communication with the shock-absorbing space and the outside of the base and causing a second end of the linear member to extend to the outside of the base.

Shock absorbing mechanism and medical instrument

A medical instrument for performing a medical procedure within a body cavity includes: an insertion part which is inserted into the body cavity and has a bending part capable of bending in a predetermined range; a manipulating part which manipulates the bending part; a wire which connects the bending part with the manipulating part; and a clutch which is provided in the manipulating part and maintains a bending state of the bending part.

Medical instrument

A tissue shredding device is provided which includes a shredding pipe which is inserted into a patient body in which a plurality of opening portions is formed in a longitudinal direction; and a plurality of wires which is withdrawn from the opening portion, bent back outside the shredding pipe, and drawn into the shredding pipe. Here, the tissue shredding device may be changed to one of a first arrangement in which the wires are withdrawn from the shredding pipe so that a tissue can be introduced toward top portions corresponding to bent-back parts of the plurality of wires, a second arrangement in which the top portions are arranged opposite to the shredding pipe, and a third arrangement in which the wires are drawn into the opening portion.
