Internally-expanded clamping and positioning device for pancreas and jejunum anastomosis

Abstract

The invention discloses an internally-expanded clamping and positioning device for pancreas and jejunum anastomosis. The internally-expanded clamping and positioning device for the pancreas and jejunum anastomosis comprises an operating handle, an adjustment mechanism, two elongating arms and expanding and contracting pliers; the adjustment mechanism used for performing clamping and positioning adjustment is arranged between the operating handle and the two elongating arms; the elongation arms are opened or closed by the adjustment mechanism; both the two elongation arms are L-shaped; the L-shaped long edges of the two elongation arms extend into the inner wall of jejunum from small holes in an intestinal wall; the expanding and contracting pliers are respectively arranged at the two tail ends of the L-shaped long edges of the two elongation arms; the jejunum is expanded by the two expanding and contracting pliers by adjusting the adjustment mechanism, so that pancreas is arranged in the jejunum in a sleeving manner and is sutured after being clamped and positioned. According to the internally-expanded clamping and positioning device for the pancreas and jejunum anastomosis, the action of expanding an intestinal segment is completed by a user with the assistance of an intestinal canal expanding manner, and the pancreas can be sleeved conveniently and quickly, so that the operational efficiency of a pancreas jejunum anastomosis surgery and the clamping and positioning success rate of the intestinal segment can be effectively improved; the blank of clamping and positioning appliances for the pancreas and jejunum anastomosis is filled, and the internally-expanded clamping and positioning device for the pancreas and jejunum anastomosis is suitable for conventional laparotomy and is also suitable for laparoscopic surgery.

Description

technical field [0001] The invention relates to a clamping and positioning device in the medical field, in particular to an internal expansion type clamping and positioning device for pancreaticojejunum anastomosis. Background technique [0002] Pancreaticojejunostomy is the preferred method for reconstructing the continuity of the pancreas and gastrointestinal tract after pancreatic surgery. At present, there are more than 30 methods of pancreaticojejunostomy reported in the literature, among which the bundled pancreaticojejunostomy designed by Professor Peng Shumai and its related improved methods are the most commonly used methods at present. It has been reported in the literature that this anastomotic method is easier to operate, easier to master, shorter operation time, and less leaky at the pancreaticojejunostomy than other anastomotic methods in its indications. The key to this anastomosis is to insert the pancreatic stump into the jejunal tube. Because the existing...
