Abstract

The invention is suitable for the technical field of medical instruments, and provides a catheter fixing device for a gastrointestinal tumor surgery. The device comprises a support and further comprises a clamping mechanism and a positioning mechanism, a first control piece drives a transmission piece to rotate, the transmission piece drives a first rack to move through a first connecting piece, the first rack drives a rotating piece to rotate through meshing teeth, when the rotating piece drives a movable piece to rotate, the rotating piece drives the movable piece to move towards the inner side in the mode that a second moving groove is in sliding connection with a fixed head and a first moving groove is in sliding connection with a fixed piece. The movable piece drives a reset piece to move towards the inner side through a connecting assembly, a second elastic piece drives the movable piece to move, and the movable piece positions the clamping mechanism in the mode that the movable piece is connected with a clamping groove in a clamped mode. The catheter fixing device can fix catheters with different diameters and is good in fixing effect, easy to operate and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a catheter fixing device for gastrointestinal tumor surgery. Background technique [0002] Gastrointestinal surgery is an important part of general surgery. Its common diseases and frequently-occurring diseases account for a large proportion in the clinical work of general surgery. At present, when gastrointestinal surgery uses catheters for clinical treatment, the catheter needs to be kept in the same position for a long time. This puts forward higher requirements on the stability and reliability of the catheter fixing device. [0003] The use steps of the existing catheter fixing device are cumbersome, the effect is not ideal, it cannot effectively prevent the catheter from moving, and increases the friction between the wound and the catheter, thereby increasing the pain of the patient and prolonging the speed of wound healing. For this reason, we A catheter fixation d...
