Fishnet-like clamping and positioning device for pancreaticojejunostomy

Abstract

The invention discloses a similar-fishing-net type pancreas and jejunum matching clamping positioning device which comprises an operating handle, an adjustment mechanism, two extension arms and clamping mechanisms. The adjustment mechanism used for carrying out clamping positioning adjustment is arranged between the operating handle and the two extension arms. Opening motions or closing motions of the extension arms are achieved through the adjustment mechanism. The two extension arms are both in L shapes, the clamping mechanisms are arranged on the inner sides of the tail ends of the L-shaped long edges of the two extension arms respectively, the L-shaped long edges of the two extension arms are arranged outside the jejunum in a sleeved mode, the lateral wall of the jejunum is clamped through the clamping mechanisms, and the jejunum is supported to be open by adjusting the adjustment mechanism through the clamping mechanisms of the two extension arms to enable the pancreas to be sleeved with the jejunum. By means of the similar-fishing-net type pancreas and jejunum matching clamping positioning device, an operator is assisted to complete jejunum expanding motions in a jejunum expanding mode, the pancreas can be rapidly and conveniently sleeved, the operating efficiency of a pancreas and jejunum matching operation and the success rate of jejunum clamping positioning can be effectively improved, the blank of pancreas and jejunum matching clamping positioning devices is filled, and the similar-fishing-net type pancreas and jejunum matching clamping positioning device is suitable for conventional laparotomy operations and laparoscopic surgeries.

Description

technical field [0001] The invention relates to a clamping and positioning device in the medical field, in particular to a fishing net-like clamping and positioning device for pancreatic-jejunum anastomosis. Background technique [0002] Pancreaticojejunostomy is the preferred method for reconstructing the continuity of the pancreas and gastrointestinal tract after pancreatic surgery, and it exists in various pancreas-related operations. Due to the deep location of the pancreas, its fragile texture and difficult suturing, complications such as pancreatic leakage often occur during pancreaticojejunostomy. The operation of pancreaticojejunostomy is complicated, and doctors need a long time of training to complete high-quality anastomosis. 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 met...
