Flexible shaft assembly of cattle abomasum left displacement surgical reduction apparatus

Abstract

The invention discloses a flexible shaft assembly of a cattle abomasum left displacement surgical reduction apparatus. The flexible shaft assembly comprises a transmission flexible shaft and a propelling unit, wherein the transmission flexible shaft comprises connecting pieces, a flexible shaft core assembly, a flexible shaft pipe assembly, a power input head and a power output key head; the two ends of the flexible shaft pipe assembly are both connected with one connecting piece, and the connecting pieces are supported on the flexible shaft core assembly through bearings; the power input headis in matched connection with the tail part of the flexible shaft core assembly; the power output key head is in matched connection with the head part of the flexible shaft core assembly; the connecting pieces comprise the pipe tail connecting piece and the pipe head connecting piece; the propelling unit comprises a guide pipe, a rotating shaft, a guide shaft, a needle storage bin and a reductionneedle with a wire binding hole, the needle storage bin is fixedly connected to the head of the guide pipe, the reduction needle is arranged in the needle storage bin, the tail part of the reductionneedle is inserted into the head of the guide shaft and fixedly connected with the guide shaft, supporting bearings sleeve the two ends of the rotating shaft, and the rotating shaft and the supportingbearings are embedded into the guide pipe; the transmission flexible shaft can be flexibly bent, the compression on internal organs is reduced, the reduction needle can be repeatedly used, and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating the left-sided displacement of the bovine abomasum. 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" incident, all free-range dairy cows have entered the breeding area, and the feeding me...

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
