Tissue traction device for assisting endoscopic treatment

Abstract

The invention discloses a tissue traction device for assisting endoscopic treatment, and relates to the technical field of endoscopic treatment assistive devices. Four arc-shaped positioning blocks are welded to the bottom of the insertion pipe in a surrounding mode, four mounting grooves are formed among the four arc-shaped positioning blocks at intervals, and a swing supporting rod is rotationally mounted in each mounting groove; two sliding rings are installed in the inserting pipe in a vertically-spaced sliding mode, and four vertical connecting shafts are symmetrically welded between the two sliding rings. Four vertical shaft holes are formed in the circumferential outer wall of the insertion pipe in a surrounding and penetrating mode and extend downwards to the four arc-shaped positioning blocks, four horizontal guide pipes are symmetrically welded to the top end section of the insertion pipe in a cross-shaped supporting mode, and an annular guide pipe is welded to the head end sections of the four horizontal guide pipes; and the four horizontal guide pipes are correspondingly communicated with the top end sections of the four vertical shaft holes. The problems that multiple suction pipes need to be manually operated before and after use, and use and operation are troublesome and time-consuming can be solved.

Description

technical field

[0001] The invention relates to the technical field of endoscopic treatment aids, in particular to a tissue traction device for assisting endoscopic treatment. Background technique

[0002] In recent years, with the rapid development of endoscopic treatment technology, many new endoscopic treatment technologies have been applied, such as endoscopic mucosal dissection, endoscopic tumor excision, endoscopic full-thickness resection, transoral endoscopic Inferior myotomy and natural orifice endoscopic surgery, etc. Due to the limitations of the device structure of the endoscope itself, tissue traction cannot be performed under the endoscope, which brings many difficulties and obstacles to the treatment under the endoscope. At present, dental floss traction and other technologies are often used in clinical assisted treatment, but this traction technology has many limitations, is cumbersome to implement, and cannot meet clinical needs.
