Abstract

The invention discloses a surgical retractor for left displacement of abomasums of dairy cattle. The surgical retractor comprises a control mechanism, a hollow connecting tube and a probe mechanism. The control mechanism comprises a grip casing, a grip joint, a power source and a wire which are disposed in the grip casing and a control switch arranged on the grip casing. The grip joint is connected to the front end of the grip casing. The probe mechanism includes a probe casing, a probe end cover and an electromagnetic coil assembly assembled in the probe casing. The probe end cover is connected to the front end of the probe casing. The electromagnetic coil assembly comprises a coil former, an enameled wire winding and an electric insert. The two ends of the connecting tube are respectively connected with the front end of the grip joint and the rear end of the probe casing, the wire is inserted in the connecting tube, one end of the wire is connected with the control switch, and the other end is connected with the electric insert. An armature is arranged in the coil former, a reset pin is arranged at the front end of the armature, a binding hole is formed in the reset pin, and a pin hole is formed in the probe end cover at the position corresponding to the reset pin. The surgical time can be reduced.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating the left displacement of the bovine abomasum, specifically, a surgical resetter for the left displacement of the bovine abomasum. Background technique [0002] Bovine abomasum displacement refers to an internal disease in which the normal anatomical position of the abomasum changes, leading to digestive system dysfunction. According to the position of the abomasum displacement, it can be divided into left abomasum displacement and abomasum right displacement, 1898 Since the earliest report on cow abomasum dislocation appeared in 2000, cow abomasum dislocation has been reported in various countries in the world, and the incidence rate has increased year by year, and at the same time it has brought significant economic losses. In recent years, with the development of the national economy, people The demand for milk and dairy products has...

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
