Problems solved by technology

[0002] In the current partial resection of the sigmoid colon and rectum, it is a routine method to insert a circular stapler through the anus to complete the colorectal anastomosis. It is easier to expand and lubricate the rectum within 15cm from the anus, but when the anastomotic site exceeds 15cm above the anus to the sigmoid colon, it is difficult to place a circular stapler with a longer specification due to the stagnation of the intestinal mucosa. Repeated adjustments during the process can easily lead to damage to the intestinal mucosa or intestinal wall, and the placement site is not ideal, which increases the risk of surgical complications. Therefore, it is necessary to design special instruments to achieve sufficient expansion and lubrication of the sigmoid colon and rectum

Embodiment Construction

[0010] Inject lubricant into the shallow groove at the tip of the sigmoid expansion rod ( figure 1 , figure 2 ), and then gradually insert the expansion rod through the anus into the rectum to the sigmoid colon ( Figure 4 ), the process can be repeated, enough lubricant can be brought into the intestinal cavity, and the anus and colorectal cavity can be fully expanded, and at the same time, the gas accumulated in the intestinal cavity can be discharged through the shallow groove, according to the scale on the surface of the expansion rod ( figure 1 ) can grasp the depth of entering the intestine, and the fully lubricated and expanded colorectal cavity can be easily placed into a circular stapler to complete the anastomosis.

[0011] Figure 4 In the shown embodiment, the sigmoid colon expansion rod is inserted into the colorectum, lubricating the intestinal cavity with lubricant, fully expanding the intestinal cavity, and discharging the gas accumulated in the intestinal c...

Abstract

In the current sigmoid colon and rectum partial resection, the conventional method finishes colorectal anastomosis by inserting a circular anastomat through an anus; the circular anastomat can be smoothly inserted just by fully expanding the sigmoid colon and rectum cavity at the remote end of a smoothing anastomotic stoma before anastomosis; and when the anastomosis part exceeds the anus by 15cm to the sigmoid colon section, because the enteric cavity is astringent, the circular anastomat with longer specification is more difficult to place, and the increase of the factor of operative complication risks is easy to cause in the placing process, a special machine needs to be designed for realizing the full expansion and smoothing of the sigmoid colon and the rectum. The invention provides the sigmoid colon expanding bar which can bring enough lubricant into the sigmoid colon and rectum cavity and fully expand the enteric cavity to solve the clinic problems.

Description

technical field [0001] The invention relates to a surgical instrument, which is an expansion lubricating instrument designed for partial resection from the upper rectum to the sigmoid colon, so as to facilitate the smooth anastomosis of the stapler. Background technique [0002] In the current partial resection of the sigmoid colon and rectum, it is a routine method to insert a circular stapler through the anus to complete the colorectal anastomosis. It is easier to expand and lubricate the rectum within 15cm from the anus, but when the anastomotic site exceeds 15cm above the anus to the sigmoid colon, it is difficult to place a circular stapler with a longer specification due to the stagnation of the intestinal mucosa. Repeated adjustments during the process can easily lead to intestinal mucosal or intestinal wall damage, unsatisfactory placement, etc., increasing the risk of surgical complications. Therefore, it is necessary to design special instruments to achieve suffici...
