Problems solved by technology

However, with this known design, the arrangement of the helical spring enclosed by the housing part of the handle has the disadvantage that it remains so even after the handle and the handle are disengaged.
The spring is inherently complex in terms of spatial structure, and this encapsulation of it leads to very poor cleanability, and in addition, in known structural designs of this type, cleaning becomes more difficult for this reason, That is, the connection of the handle to the handle is achieved by an additional mechanism with a permanent cover, which further makes cleaning significantly more difficult

Embodiment Construction

[0013] The drawing shows a surgical clamp 1 with a tubular handle 2, on its distal end a clamp jaw 3 with two movable branches 4, 5 which are rotatable about an axis 6 support.

[0014] A link 7 passing through the shank acts on the pliers jaw 3 and turns the branches 4 , 5 relative to each other during a longitudinal movement along the shank 2 . When the connecting rod 7 is pulled back in the direction of the arrow 8, a closing force is applied to the branches 4, 5, closing them up to the fully closed position.

[0015] On the proximal end region of the clamp 1, a two-pole plug 9 is arranged, to which an electrically conductive connection cable (not shown) can be connected in order to connect the plug to a high-frequency power supply. Two conductive connecting wires 10,11 pass through the handle 2 from the plug 9 to the jaw 3 of the clamp in the inside of the clamp, and are connected to the electrodes not shown on the active surface of the branch 4,5 there, so as to They de...

Abstract

A surgical clamp (1) is provided with branch parts (4, 5) which are articulated on the far-middle end of tubular handle part (2) with a mode of movable with each other. The branch parts are driven by a handle (15) through the relative movement of connecting rod (7) penetrating a shank through the shank. In two handle components (14, 16) of handle, the handle component (16) of connecting rod is detachably articulated on the far-middle end of connecting rod (7), and the handle component (14) of shank is connected with the near-middle end of handle through a sleeve (21). The sleeve surrounds the connecting rod (7) and is supported on the handle component (14) of shank with a mode that the longitudinal movement is allowed. The sleeve is detachable fixed on the near-middle end of shank and is surrounded by a spiral spring (19) which is supported on the sleeve with the far-middle end and is supported on the handle component of shank with the near-middle end. The invention is characterized in that the sleeve is installed to project from the handle component of shank with a mode of supporting at least one bigger component of the area of spiral spring in the far-middle direction.

Description

technical field [0001] The invention relates to a surgical clamp of the type specified in the preamble of claim 1 . Background technique [0002] These clamps have an elongated handle for endoscopic use. Since the sleeve is detachably connected to the handle, the tongs are detachable from each other at this point between the handle and the handle. This detachability firstly offers the possibility of improved cleaning and disinfection, so that the clamps can be reused even after bacterial-infested surgical operations. [0003] These clamps are also equipped with a spring which flexes elastically with a high closing force when the clamps are closed. This can be used for different purposes, such as limiting overloading, to prevent tong destruction, or to maintain a constant force for a longer period of time in combination with a tong locking mechanism. [0004] A clamp of this type is known from DE 29917554 U1. However, with this known design, the arrangement of the helical...
