Embodiment Construction

[0096] Figure 1a and 1b A surgical instrument 1 is shown comprising a handle 2 , a hollow shaft 3 and an end effector 4 . The hollow shaft 3 is an elongated body made of a suitable material, such as stainless steel or carbon fiber reinforced composite material. image 3 - A polyaxial joint 6 , shown in more detail in FIG. 12 , couples the distal end 2 a of the handle 2 to the proximal end 3 a of the hollow shaft 3 .

[0097] A "surgical instrument" is a device by which tissue of a patient is contacted by another individual, such as a surgeon. In this application, the term "surgical instrument" includes devices such as prostheses or implants.

[0098] By "proximal end" is meant the end of the component that is closest to the handle, and thus to the individual holding the handle of the surgical instrument. Accordingly, "distal end" refers to the end of the component furthest from the handle and the individual holding the handle.

[0099] Such as Figure 1a-1b and Figure ...

Abstract

The present invention relates to a surgical instrument (1) comprising a handle (2), a hollow shaft (3), and an end effector (4) coupled to a distal end (3b) of the hollow shaft (3), the end effector (4) being operatively connected to the handle (2) through operating means (5) extending within the hollow shaft (3). A multiaxial joint (6) couples a distal end (2a) of the handle (2) to a proximal end (3a) of the hollow shaft (3), the multiaxial joint (6) allowing multiaxial rotation of the hollow shaft (3) in relation to the handle (2). The multiaxial rotation includes rotation of the hollow shaft (3) around a center axis (C) of the hollow shaft (3), and rotation in at least two planes in relation to the distal end (2a) of the handle (2).

Description

technical field [0001] The present disclosure relates to a surgical instrument for minimally invasive surgery that includes a handle, an end effector operatively connected to the handle, and a hollow shaft connecting the handle to the end effector. Background technique [0002] Minimally invasive procedures require surgical instruments that engage tissue through small incisions or natural orifices in the patient's body, and typically reduce recovery time and the amount of complications compared to traditional open surgery. [0003] Minimally invasive surgery also requires some versatility embedded in the instrument so that the user has the best possible conditions for engaging tissue. These conditions include allowing the user to ergonomically hold the handle of the surgical instrument, for example allowing the user to keep their wrist straight. [0004] EP1836986 discloses a surgical instrument comprising a ball and socket joint connecting the handle to the shaft, allowing...
