1. A method of assembling a surgical device, the surgical device comprising a detachable transducer module and a handle defining a cavity, wherein the transducer module is operable to generate ultrasonic vibrations in response to electrical power, wherein the transducer module comprises a switch member, wherein the handle comprises a shaft assembly and an activation feature, wherein the activation feature comprises at least one lever member operable to directly engage the switch member of the transducer module to selectively activate the transducer module, wherein at least part of the shaft assembly is configured to acoustically communicate with the transducer module such that the at least part of the shaft assembly is operable to transmit ultrasonic vibrations from the transducer module, the method comprising:
(a) angling the transducer module downwardly toward the cavity;
(b) coupling the transducer module with the shaft assembly;
(c) registering the switch member of the transducer module by causing the lever member of the activation feature of the handle to directly engage the switch member of the transducer module; and
(d) depressing the transducer module into the cavity to fully seat the transducer module in the cavity.
2. The method of claim 1, wherein the transducer module further comprises a waveguide having a head portion, wherein the shaft assembly further comprises a waveguide having a head receiving portion, wherein the act of coupling the transducer module with the shaft assembly comprises inserting the head portion into the head receiving portion.
3. The method of claim 1, further comprising engaging a locking feature of the transducer module with a locking feature of the handle to selectively secure the transducer module relative to the handle.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A sheet, a plate, a bar or a wire which is made of titanium and has high ductility and low material anisotropy in a plate plane of a sheet or a plate, or in a sectional plane of a bar or a wire, characterized by: containing, in mass, Fe at 0.15 to 0.5%, nitrogen at 0.015 to 0.04% and oxygen, with the balance consisting of titanium and unavoidable impurities; and when the Fe content is defined as Fe, the nitrogen content as N and the oxygen content as O, the oxygen equivalent value Q=O+2.77N+0.1Fe being 0.11 to 0.28.
2. A sheet, a plate, a bar or a wire which is made of titanium and has high ductility and low material anisotropy in a plate plane of a sheet or a plate, or in a sectional plane of a bar or a wire according to claim 1, characterized by: the oxygen equivalent value Q being 0.11 to 0.17.
3. A titanium sheet or plate having high ductility and low material anisotropy in a plate plane according to claim 1 or 2, characterized in that the titanium sheet or plate is a hot-rolled or cold-rolled strip, or a sheet or a plate cut out therefrom.
4. A titanium bar or wire having high ductility and low material anisotropy in a sectional plane according to claim 1 or 2, characterized in that the titanium bar or wire is a hot-rolled or cold-drawn coil or a bar or wire cut out therefrom.
