In the wire-pulley drive mechanism, the mechanical design about the arrangement of pulleys and routing of wires is very important to keep the curvature radius of wires and to reduce distance between joints. The wrist mechanism proposed by Kymerax [ 6 ] adopts a combination of wire-pulley drive and gear drive mechanism [ 10 ].
Further, we have proposed another type of wire-pulley and gear drive mechanism [ 11 , 12 ]. Nishizawa and Kobayashi proposed a non-interference mechanism using wire-pulley and gears mechanism [ 13 ]. In this mechanism, in addition to wire-pulley design, strength design of gears and manufacturing accuracy of parts to reduce gear backlash are very important. The wrist mechanism of the Radius [ 5 ] adopts the combination of torque tube, gear, and link drive mechanism [ 14 ].
Also, Fujii et al.

Similarly, strength design of gears and manufacturing accuracy of parts to reduce gear backlash in torque tube and gear drive mechanism are very important.
The Autonomy [ 3 ] and the FlexDex [ 4 ] adopted a flexible bending joint and wire drive mechanism [ 16 , 17 ]. Haraguchi et al.
The bending mechanisms using flexible joint are very simple.

Since the bending radius of the flexible joint is large with respect to the forceps diameter, large motion is required to determine the posture of the end effector. With a forceps using a flexible bending joint, the procedure in a narrow space is difficult. Moreover, link drive mechanisms [ 19 , 20 ] and parallel link mechanisms [ 21 — 23 ] are proposed. Ishii and Kobayashi propose a parallel link mechanism using double-screw-drive mechanism [ 24 ].
Arata et al. Also, link drive mechanisms need a lot of components and manufacturing accuracy of parts to reduce link backlash, and the cost increases. Considering the need for a compact and maneuverable wrist mechanism for robot-assisted laparoscopic forceps, this study aims to propose a new wrist mechanism using wire-pulley drive mechanism.
This paper first examines the most important specifications required for such a wrist mechanism. Next, a new wrist mechanism is proposed to satisfy those specifications, with a basic design and forward and inverse kinematics analyses.
Third, a prototype model of the wrist mechanism is detailed. Finally, the paper reports the experimental results using a test bench to confirm the effectiveness of the mechanism. This section presents the required specifications and the mechanical design of a wrist mechanism for articulated forceps used in robot-assisted laparoscopic surgery.
Configuration of the degrees of freedom Generally, three axes are required to allow any posture of an end effector. In case of master—slave manipulators and articulated forceps for laparoscopic surgery, mostly, the first axis that is the most proximal side axis for the posture of the wrist axes is the roll axis of rotation of the forceps shaft by manual or motor drive to simplify the wrist mechanism.
Generally, for the second and third axis for the posture of the wrist axes, combination of bending axis, roll axis, and curvature axis, among others are applied. There are three kinds of combinations of the second and third axis for clinical use articulated forcipes of laparoscopic surgery [ 7 , 10 , 15 — 17 ].
As stated previously, J Hepatobiliary Pancreat Surg also similar. Therefore, when techniques were compared for all the items reviewed, no large differences were noted between them. The principle disadvantage of the laparoscopic approach is the difficult and lengthy learning curve required.
The principle advantage of the laparoscopic Whipple procedure is that it is a minimally invasive with all the advantages that that offers. However, although no benefit seemed to be derived from use of a laparoscopic approach, randomized controlled trials must be performed to achieve strong conclusions.
One major concern always raised in cases of malignant disease treated by laparoscopy is whether this surgery is an adequate cancer operation, allowing tumor-free margins and sufficiently extensive lymph node dissection while being minimally invasive . In review of the literature, the authors observed that extended lymphadenectomy is not necessary, because it does not prolong patient survival.
Laparoscopic surgery causes less immunodeficiency with the open approach, which seems to be an important advantage for cancer patients.
Conclusion This review demonstrates that the laparoscopic Whipple Fig. However, the laparo- laparoscopic pancreatectomy series remain small, particu- scopic Whipple procedure should be performed in selected larly those on Whipple procedures. In case of doubt or with cephalic pancreatic cancer, was published in , difficulties in the dissection, an open resection should be and 13 cases could be finished laparoscopically with good performed.
In the review of the literature, we found good results, but the laparoscopic approach is not universally accepted as the best one because of long operating time, technically diffi- References cult procedure, and a lack of reduction in length of hospital 1.
