摘要:
A medical instrument has a tube-like element, a handle bent off from said tube-like element, an endoscope having a shaft, a camera module connected to said endoscope, a light pipe and a guide provided on said tube-like element for receiving said shaft of said endoscope. The endoscope is provided with at least two coupling elements extending in a direction of said bent-off handle and into an inside of said handle, one of said at least two coupling elements is coupled to said light pipe, another of said at least two coupling elements is coupled to said camera module, and said camera module is disposed inside of said handle.

A medical instrument has several components and being disassemblable into said several components, one of said components being rotatable with respect to another of said several components by means of a rotary element arranged on said another of said several components. A coupling for a detachable rotationally engaged connection of said one component or to said rotary element is provided, said coupling having two coupling halves engaging into one another along a coupling axis. On each of said coupling halves at least one tooth is arranged, each tooth is disposed at a radial spacing from said coupling axis. Adjacent to each tooth in a circumferential direction at least one gap is provided, into which gap of one coupling half a tooth of the other coupling half enters and fits, and each tooth is equipped in the circumferential direction with a bevel.

A coupling serves for leakproof connection of two shaft-like medical instruments (10, 90) along their shaft axis (53, 97), in particular for connection of an arthroscope shaft to an optical system. A coupling element (80) is provided, arranged on a first instrument (10) and having a contact surface (66), against whose contact surface (66) a contact surface (106) of a coupling element (92) of the second instrument (90) can be applied. Also provided is an interlock system for releasable interlocking of the two coupling elements (80, 92), the contact surfaces (64, 106) resting against one another in leakproof fashion. For easier handling, it is proposed that the interlock system have a slider (44) which is displaceable transversely to the coupling axis (53), is arranged in transversely displaceable fashion on one of the two coupling elements (80), and in a first slide position allows the two coupling elements (80, 92) to be applied against one another and in a second locking slide position mechanically interlocks the two coupling elements (80, 92). A component (58) having the contact surface (66) of at least one coupling element (80) is displaceable in the direction of the coupling axis (53).

A coupling assembly for connecting a handle to an instrument extending along a longitudinal axis has a coupler, which releasably receives the handle and has an outer sleeve and a snap-in sleeve formed with a snap-in element. The handle has a recess receiving the snap-in element which is guided along a conical recess formed in the outer sleeve to move to a locking position wherein the handle and the coupler are displaceably fixed relative each other. The outer sleeve is rotatable about the longitudinal axis and its recess has a periphery formed with an inner surface enabling the snap-in element to move radially from the locking position during rotation so as the handle can be axially withdrawn from the coupler.

A trocar sleeve comprises at its proximal side a housing, from the distal side of which a shaft projects. Further, a sealing of elastic material is provided in order to seal an instrument inserted into the trocar sleeve gas-tight into the proximal direction. The sealing comprises a central opening, the diameter of which is variable. A spreading device is provided which is insertable into the sealing, extending same in doing so, whereby the diameter of the central opening is enlargeable.It is suggested to configure the spreading device as an axially movable sleeve, the ring-shaped front area of which is insertable into the sealing, spreading same in doing so.
摘要:
A surgical thread cutter (10) has a blade (18) movable via an actuation mechanism (30) relative to an anvil (20) toward and away from the latter, and a spring by way of which the blade (18) can be acted upon by spring force in one movement direction. In the interest of better and safer handling, it is proposed that the spring act upon the blade (18) in the cutting direction, that a retention system be provided by means of which the blade (18) can be locked in a position remote from the anvil (20); and that the force of the spring be set in such a way that after the retention system is released, the blade (18) can be moved onto the anvil (20) in the manner of a guillotine (FIG. 1).
