Problems solved by technology

Applicants have found, however, that movement of the end or pivot portion makes control less predictable in use and reduces the feedback the surgeon receives from the instrument.
For this reason, some surgeons prefer to use handles without articulating connections or pivoting parts, despite the problem that the wrist sometimes rotates to extreme angles

Embodiment Construction

[0044] Figure 1A A perspective view depicting an embodiment of the handle 2 of the present invention. exist figure 2 depicted in Figure 1A A cross-section of an example. The handle 2 comprises a first part and a second part 6 pivotally connected (pivotably connected) to each other. The first part comprises a body part 4a and an end part 4b pivotally connected to the body part 4a. The axis of the pivotal connection between the end portion 4b and the body portion 4a is substantially perpendicular to the axis of the pivotal connection between the first part and the second part 6 .

[0045] Figure 1B and 1C depicts Figure 1A A perspective view of an embodiment of the present invention, which has an end portion 4b in a different position relative to the main body portion 4a.

[0046] The second part 6 and the end 4b include an opening 8 sized to receive one or more fingers of a user in use. Preferably, the opening 8 is dimensioned such that a user can insert one or more ...

Abstract

A handle (3) for a surgical instrument, and in particular a handle for use with keyhole surgery, endoscopic and laparoscopic instruments is disclosed. In one embodiment, the present invention provides a handle for a surgical instrument comprising one part with a pivoting or articulated end portion (4b), and a means for indexing the pivoting movement of the end portion. The indexing means allows adjustment of the angle of the end portion together with improved control and tactile feedback to the user. In another aspect, the present invention provides a handle for a surgical instrument comprising one part with a pivoting or articulated end portion, and a means for locking the movement of the end portion. The locking means can be moved between locked and unlocked positions. The end portion can be pivoted or articulated to a desired angle and the locking means moved to a position to prevent movement of the end portion holding it at the desired angle. This improves control and tactile feedback to the user.

Description

technical field [0001] This invention relates to handles for surgical instruments, and in particular to handles for keyhole surgical, endoscopic and laparoscopic instruments. The present application also relates to surgical instrument assemblies and systems including said handles. Background technique [0002] Keyhole surgery, endoscopy and laparoscopy techniques are well known and have been developed to allow surgery with smaller incisions than before. In general, the technique requires insertion of a long, thin instrument into a body cavity through a small incision. The instruments may include endoscopes for viewing body cavities and one or more other instruments for performing surgical procedures, such as biopsies. [0003] The surgical instruments used in these techniques are controlled by a handle attached to the shaft of the instrument. The handle allows the surgeon to manipulate the instrument and manipulate it as desired. One form of handle that is widely used in...
