Abstract

The open-circuit cone comprises a holding handle and an open-circuit assembly which are connected through a supporting assembly, a strength supporting assembly is installed in the holding handle, the supporting assembly comprises a pair of supporting rods, a steering limiting groove and a rotating sliding groove are formed in the top ends of the supporting rods, and the open-circuit assembly comprises a cone head. A pair of rotary supporting rods is arranged in the middle of the rotary base, the rotary supporting rods can drive the rotary base to move along the rotary sliding groove and rotate between the pair of supporting rods with the rotary supporting rods as axes, and a positioning needle containing bin used for containing a positioning needle assembly is further formed in the bottom of the rotary base. The positioning needle assembly comprises a first positioning needle and a second positioning needle which are different in connecting body and different in needle body penetrating depth through the needle handle, the structure is reasonable, operation is easy and convenient, the mouth gag, the opening awl and the positioning needle placing device are integrated, the device is suitable for field spine surgery, personnel and time cost is saved, and the success rate of the surgery is increased.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a spinal surgery instrument, in particular to an opening cone with a positioning needle assembly for field spinal surgery. Background technique [0002] For people with spinal injuries in modern wars or natural disasters, medical staff often need to perform emergency field spinal surgery on people with spinal injuries. During the operation, screws need to be used to fix the fractured bones. Before the screws are implanted, an opening is required. Make a hole on the pedicle with a tool, and then drill the hole forward to the required depth with the open-path awl. During this period, it is necessary to place the positioning pin several times to assist in fluoroscopy to determine whether the screw channel has been opened to the required depth. The above screw channel preparations are in progress Surgical instruments are numerous, the steps are complicated, and the accuracy...
