Left cow abomasum displacement replacer with openable and closable launching tube

Abstract

The invention discloses a left cow abomasum displacement replacer with an openable and closable launching tube. The left cow abomasum displacement replacer comprises a replacement needle launcher and a replacement needle, the replacement needle launcher comprises the launching tube, a launching portion and a trigger, the replacement needle is a straight needle, the launching tube comprises a left half tube and a right half tube which are matched in opening and closing under control of an opening and closing mechanism, and a suture passing hole is further formed in the upper portion of the launching tube. By the left cow abomasum displacement replacer, traditional two-side incision surgeries can be simplified to one-side incision surgeries, and survival probability of cows suffering from serious diseases is effectively increased, and the replacement needle can be fed to a set location even for large-sized cows; besides, the replacement needle can be protected effectively, accidents are decreased, and surgery success rate is increased; since the openable and closable launching tube is arranged, sutures cannot be pressed in a tube cavity of the launching cavity to affect launching of the replacement tube, and launching success rate of a surgical replacement device is effectively increased.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating bovine abomasum left displacement, specifically, a bovine abomasum left displacement reseter with an openable and closable launch tube. 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. Especially after the "melamine" in...

AI Technical Summary

Problems solved by technology

[0015] However, the standard omentum fixation method with incision in the left hip has its disadvantages during the operation.

[0016] 1. Due to simultaneous incisions on both sides of the abdominal wall, there are many wounds, great tissue damage, easy infection, and slow wound healing, which is a great burden on sick cattle

[0017] 2. When the operator moves the needle and thread to the right abdominal wall in the abdominal cavity, if the cow suddenly moves or shakes, the operator will accidentally drop the needle into the cow's abdomen or pierce the cow's internal organs, which will cause great damage to the cow

[0018] 3. Some cows have very large physiques. During the actual operation, the operator takes off his shirt and puts his entire arm into the cow's abdomen. However, he still cannot reach the target position on the right abdominal wall, so he can only choose the lower right abdominal wall Fixed position, resulting in recurrence of left displacement
