Operation apparatus for surgery department

Abstract

The invention relates to an operation apparatus for the surgery department. The operation apparatus comprises a shell, a nail anvil assembly arranged at one side of the shell, a nail bin assembly support forming a tong opening with the nail anvil assembly, a nail bin assembly installed on the nail bin assembly support, an occlusion driving assembly driving the tong opening to be opened or closed,a percussing rod and a cutting assembly arranged on the percussing rod and driven by the percussing rod; the operation apparatus is characterized by further comprising a power input device, an occlusion transmission assembly, a percussing transmission assembly and a switching part, the power input device comprises a motor, and the switching part selectively transmits power of the power input device to the occlusion driving assembly through the occlusion transmission assembly or to the percussing rod through the percussing transmission assembly. The operation apparatus can achieve electric control, then the applied force can be precisely controlled, sewed tissue is prevented from being excessively extruded, and the coinciding effect is improved.

Description

technical field [0001] The present invention relates to a surgical instrument. Background technique [0002] In general surgical treatment, staplers are often used to complete the function of tissue cutting and anastomosis. Existing staplers mostly rely on manual disposable instruments. In surgery, the doctor often needs to rotate the knob at the end to close the proximal and distal tissues, and then close the firing rod with both hands to complete the anastomosis. The firing process requires a huge firing force to complete the cutting and closure of the anastomotic stoma, and the huge closing force brings about the shaking of the arm during the firing process and leads to excessive pulling, which affects the butt closure and success of the anastomotic stoma on the sutured tissue. In addition, due to the manual firing, the firing force cannot be controlled, resulting in excessive extrusion of the sutured tissue. If the staples are incomplete or excessive extrusion, it will...

AI Technical Summary

Problems solved by technology

The firing process requires a huge firing force to complete the cutting and closing of the anastomotic stoma, and the huge closing force brings about the shaking of the arm during the firing process and leads to excessive pulling, which affects the butt closure and success of the anastomotic stoma on the sutured tissue. In addition, due to the manual firing, the firing force cannot be controlled, resulting in excessive extrusion of the sutured tissue. If the staples are incomplete or excessive extrusion, it will lead to potential leakage and irregular narrowing of the anastomosis, affecting Surgical effects and detrimental to the patient's postoperative recovery

In addition, the closing speed of the manual knob is slow and unstable
