Organ suctioning and gripping tool

Abstract

The purpose of the present invention is to provide an organ suctioning and gripping tool which is capable of decreasing the height of a suctioning and gripping tool, ensuring the field of view of an endoscope, and ensuring operation space, and in which a suction disk deals with even a deformation of the organ and is not easily detached. An organ suctioning and gripping tool (1) according to the present invention is provided with a suctioning tube body (2), wherein a plurality of suction disks (10a, 10b, 10c) for organ suctioning are provided to a front end section of the tube body, and an organ is suctioned by the suction force of the suction disks and is lifted and gripped. The plurality of suction disks are retained by a ring-shaped retainer (9) provided to the front end section of the tube body, and an annular flange part (27) is provided to an open end section of each of the suction disks.

Description

technical field [0001] The present invention relates to an organ suction gripper, and more specifically, relates to a technique for easily performing surgery by sucking the surface of an organ such as a lung and grasping it in a raised manner during surgical operations using an endoscope, for example. . Background technique [0002] In surgery, in order to facilitate the treatment of the affected part, it is necessary to perform operations such as lifting and squeezing organs that obstruct the field of view. In thoracotomy / laparotomy, the operator's hands and surgical stabilizers are used to lift up, but in minimally invasive surgery using an endoscope, due to indwelling in a small incision The trocar is inserted into the surgical instrument through the trocar, so large instruments cannot be inserted into the body cavity, and forceps etc. are used for lifting. [0003] In addition, the applicant previously applied for Japanese Patent Laid-Open No. 2017-202093 (Patent Docum...

AI Technical Summary

Problems solved by technology

However, in the actual use of the viscera suction grasper of this patent document 1, in a limited space (inside the chest cavity), sometimes there are drum-shaped parts and its height (length in the axial direction) is too high, so there are difficulties in handling and handling. wait to deal with bad problems

[0004] In addition, since a plurality of suction cups are covered by a drum-shaped member from behind, the field of view of the endoscope is blocked, and there is a problem that the space for performing surgery is narrowed.

[0005] Furthermore, when sucking and holding the lungs (especially lateral traction), the lungs are soft and easily deformed, and the suction cup cannot correspond to this change, and there is also a problem of falling off and slipping due to gaps.
