Description

Perineum lifting device for rectal surgery

The technical field is as follows:

the invention relates to the field of medical instruments, in particular to a perineum lifting device for rectal surgery.

Background art:

the difficulty of radical operation of rectal cancer is the dissociation of the lower rectum, especially the terminal rectum near the dentate line. The main reason is that the deep position is around the bony structure space and the expansion is not opened, and if the visceral fat hypertrophy is combined, the tumor volume is larger, the male has difficulty in the pelvis (the distance between the two ischial spines is less than 10 cm) and the like, the exposure and the dissociation of the end rectum are more difficult.

Since the rectum is a three-dimensional tubular structure, the appearance of the rectum is increased in the operation by improving the surrounding spatial structure of the rectum, but in the prior methods, clinicians improve the appearance of the rectum by suspending the bladder (female is uterus), laterally drawing the rectum and applying three-leaf or five-leaf forceps on the plane formed by the x axis and the y axis, but in practice, the real appearance of the rectum is difficult to realize, namely, the end of the rectum is 3-5cm, because the end of the rectum is positioned behind the pubic symphysis, and the periphery, particularly the front of the rectum is lack of the exposed space on the plane formed by the x axis and the y axis due to the existence of the bony structure, but in the practical work, the spatial position of the end of the rectum is not fixed on the z axis, if a force along the longitudinal axis of the anal tube is applied to the perineum, the perineum can be lifted upwards by 3-5cm, which is sufficient to improve the exposure of the terminal rectum. The rectum is easy and relaxed to free.

Also can adopt artifical fist mode lifting perineum that pushes away in current operation, this kind of mode exists that the lifting time is short, and the power direction is unstable, occupies limited operating table operating space, influences the operation scheduling problem of art person. Therefore, the perineum lifting device is designed and invented to reduce the operation difficulty and improve the operation fluency.

The invention content is as follows:

the invention aims to overcome the defects in the prior art and provides a perineum lifting device for rectal surgery.
