Operation repositor having external endoscope and being used for left displacement of abomasum of cow

Abstract

The invention discloses an operation repositor having an external endoscope and being used for left displacement of abomasum of cows. The operation repository comprises a high-pressure air source, a suture line, a reset needle, and a propelling device. The propelling device is externally provided with a portable endoscope. The outer edge of the propelling device is smooth. The propelling device comprises a propelling unit, an air supply unit which is on the tail part of the propelling unit and is connected with the propelling unit, and a needle storage bin which can hold the reset needle. Theair supply unit comprises a gas pipe and a connector. The head of the needle storage bin is provided with a needle outlet hole for the reset needle to pass through. The needle storage bin is providedwith a line leading groove on the needle outlet hole. The propelling unit comprises a main cylinder, an air cylinder, a piston, a piston rod, and a buffer cushion. The tail part of the air cylinder isout of the main cylinder and is connected with the connector of the air supply unit. The piston rod passes through a guide pipe which is arranged on the bottom of the main cylinder and enters the needle storage bin. The tail part of the reset needle is fixed on the head of the piston rod. The gas pipe is connected with the high-pressure air source. The gas pipe can be flexibly bended, and reducescompression on visceral organs, and reduces operation time.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating left-sided abomasum dislocation of bovine abomasum, specifically, a surgical resetter for left-sided abomasum dislocation of bovine abomasum with an external endoscope. Background technique [0002] Cattle abomasum displacement refers to an internal medical disease in which the normal anatomical position of the abomasum changes, leading to digestive system dysfunction. According to the position of abomasum displacement, it can be divided into left abomasum displacement and abomasum right displacement. Since the first report of cow abomasum dislocation appeared in 1898, cow abomasum dislocation has been reported all over the world. In recent years, with the development of the national economy, people's demand for milk and dairy products has increased, and the scale of intensive dairy cow breeding in my country has expanded rapidly.

Problems solved by technology

[0016] 1. The operator is holding (CN103690269B, a bovine abomasum left displacement operation resetting device with a reset needle range), extending into the abdomen of the cow and passing under the rumen of the cow, and pressing the launch tube into the right abdomen of the cow. Trigger control, when moving to the right abdominal wall in the abdominal cavity, if the cow suddenly moves or shakes, and the surgeon accidentally pulls the trigger, the reset needle may fall into the cow’s abdomen or pierce the cow’s internal organs, which will cause great damage to the cow

[0017] 2. The operator is holding (CN103690269B, a bovine abomasum left displacement surgery reset device with reset needle range), and some cattle are very large, so even if the launch tube can touch the right abdomen of the cow, the launch tube needs to be very long , the launch tube of the device must be straight, so when it touches the right abdomen of the cow, it will definitely compress the cow's internal organs and cause damage to the cow

[0018] 3. The operator is holding (CN103690269B, bovine abomasum left displacement surgery reset device with reset needle range), pulls the trigger, and the ejection part shoots out the reset needle, and leads the second and third fixed wires to the right side In the abdominal cavity, or every time an operation is performed, the reset needle needs to be reinstalled, which may be lost or contaminated during the reinstallation process, which greatly wastes time and prolongs the operation time

[0019] 4. The operator is holding (CN103690269B, bovine abomasum left displacement operation resetting device with reset needle range), and can only grope for positioning in the abdominal cavity of the cow during the operation, prolonging the operation time
