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. The standard surgical procedure requires a treatment team consisting of at least 2 people, and the surgical process is complicated, especially in the process of delivering the fixed line to the right abdominal wall, which requires good cooperation between the surgeon and assistants. A group of surgical personnel Often only one operation can be completed in half a day

Embodiment 1

[0049] Such as Figure 1 to Figure 7 As shown, the bovine abomasum left displacement surgery reset device by pressing and pushing needles of the present invention includes a reset needle pressing device 1 and a reset needle 2 that can be loaded into the reset needle pressing device 1, and the reset needle pressing device 1 It includes a positioning plate 11 and a handle 13 that can press the reset pin 2. The positioning plate 11 is provided with a through hole 11a for inserting the reset pin 2. There is a gap between the positioning plate 11 and the handle 13 that can be compressed under the pressure of the handle 13. The telescopic frame 12 is provided with a return spring 14 in the telescopic frame 12, and the reset pin 2 is a straight needle.

[0050] A friction block 4 is provided inside the telescopic frame 12 or inside the handle 13, and the position of the friction block 4 corresponds to the through hole 11a, and the reset pin 2 can be inserted into the friction block 4...

Embodiment 2

[0058] The voice-activated positioning device 3 is installed in the positioning plate 11, and the voice-activated positioning device 3 includes a magnetic induction block 34 which is slidably arranged. The magnetic induction block 34 is connected with a magnetic induction block return spring 35. 32 and a switch 33, the switch 33 includes a moving contact block 33a and a static contact block 33b, the moving contact block 33a is fixed on the magnetic induction block 34. One end of the return spring 35 of the magnetic induction block is fixedly connected with the front end of the positioning plate 11 , and the other end is fixedly connected with the magnetic induction block 34 .

[0059] The radius of the through hole 11a is twice the sum of the radius of the needle body of the reset needle 2 and the diameter of the No. 18 suture.

[0060] The parts not described are the same as in Example 1.

[0061] Embodiment 2 does not require the cooperation of an assistant, and the operato...

Abstract

The invention discloses a cow LDA operation reset device by pressing a push needle. The cow LDA operation reset device comprises a reset needle pressing device and a reset needle, wherein the reset needle is provided with a wire bonding hole. The outer edge of the reset needle pressing device is smooth, and the reset needle pressing device comprises a transmitting tube, an ejection portion and an electromagnetic induction device. The reset needle is a straight needle, the back end of the reset needle is located in the ejection portion, and other parts of the reset needle are located in the transmitting tube. The ejection portion comprises a blowing head, and a clamping shoulder is arranged on the blowing head. The reset needle pressing device further comprises a limiting device, and the limiting device and the clamping shoulder can be clamped. The electromagnetic induction device comprises an electromagnet arranged in a sliding mode, and the electromagnet is in linkage fit with the limiting device. By means of the cow LDA operation reset device, the operation can be simplified into an operation with one side incised, and the survival rate of cows with serious diseases can be effectively improved; the reset needle can be delivered to an object position conveniently, the reset needle can be protected effectively, and the accidents that internal organs are pricked by the reset needle can be reduced; through the adoption of voice control positioning, there is no need for an assistant to help from the right side, and the cow LDA operation can be completed just by one person.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating the left abomasum displacement of bovine abomasum. Specifically, it is a surgical reset device for the left abomasum displacement of bovine abomasum by pressing and pushing needles. 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 expand...
