Embodiment Construction

[0045] figure 1 A perspective view of a surgical instrument 1 according to the invention (eg with gripper and / or scissors and / or forceps design) is shown. To this end, the female instrument part 2 is operatively coupled (in a scissors-like manner) to the male instrument part 8 such that they are pivotable relative to each other about the pivot axis 7 . Via the proximal gripping portion 20 at each instrument portion 2, 8, they can be manually pivoted relative to each other such that the distal jaw portion 21 of the surgical instrument 1 is actuated, preferably defining the The two branches are moved / rotated in a gripper / scissors / tweezers-like manner to increase and / or decrease the joint gap formed between them. The jaw portion 21 may perform a clamping, cutting, holding function or any other surgical function. Preferably, the present jaw portion 21 is a clamp.

[0046] In the coupling region 3 of the two instrument parts (arms) 2 , 8 the insertion end is realized. The funct...

Abstract

The invention relates to a surgical instrument (1) comprising a female branch (2) defining in a coupling region (3) a hollow comprising internal coupling surfaces (5, 6) facing inwardly volume (4), and the surgical instrument comprises a male branch (8), which is at least partially pivotable within the hollow volume (4) about a pivot axis (7) relative to the female branch (2) , the male branch (8) defines in the coupling region (3) a guide portion (9) with an external coupling surface (10, 11) facing outwards, and the external coupling recess (12) is arranged on the external coupling surface ( 10, 11), wherein the internal coupling recess (13) is arranged on the internal coupling surface (5, 6), the internal coupling recess (13) is different from the longitudinal axis (14) of the surgical instrument (1) It extends in the direction of the direction of the external coupling recess (12).

Description

technical field [0001] The invention relates to a surgical instrument comprising at least two instrument parts pivotable relative to each other, or comprising at least one fixed instrument part and one movable (eg , Branch spring on the rod) instrument part. Surgical / medical instruments of the type according to the invention may for example essentially be clamps, clamping devices, cutting devices and / or holding devices of any geometry used in surgery. Background technique [0002] Surgical instruments that ensure relative movement between branches / instrument parts are used in almost all medical fields. Efficiency is becoming increasingly important as is thorough decontamination / disinfection / sterilization of used instruments. The reason for this is, on the one hand, in order to achieve ever higher quality standards for disinfection and, on the other hand, the available disinfection time intervals are progressively reduced. The pivoting of two or more branches / instrument pa...
