The invention provides a surgical device. The device comprises an outer sleeve, a transmission rod, a thread hooking rod, a knot pressing device, a thread pulling ring and a handle. The far end of thehandle is connected to the near end of the outer sleeve, the far end of the outer sleeve is connected to the knot pressing device, the near end of the thread hooking rod is connected to the handle, the thread hooking rod penetrates the cavity of the transmission rod, the transmission rod is arranged in the cavity of the outer sleeve, the three parts are coaxial, the near end of the three parts isprovided with a through hole, and the thread pulling ring is arranged in the through hole. The outer sleeve and the transmission rod are provided with flexible sections which can be freely bent; a boss and a threading ring are arranged on the thread hooking rod, and a groove is arranged in the cavity of the transmission rod; and the handle is provided with a wrench and a shifting rod which can complete the transmission of the axial force of the thread hooking rod and the matching or separation of the boss on the thread hooking rod and the groove in the transmission rod, and the handle is alsoprovided with a turntable which can complete the control of the bending angle of the flexible section of the outer sleeve. After the device extends into a cavity, positioning, sewing and knotting operations can be completed by controlling turntable knobs, the shifting rod and the wrench on the handle, and residual suture threads in the cavity of the device can be withdrawn by controlling the thread pulling ring.
Description
technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a surgical instrument which can be positioned conveniently in a minimally invasive environment and can be knotted continuously. Background technique [0002] Traditional surgical operations usually have large wounds, heavy bleeding, long recovery time, and leave relatively obvious scars. With the advancement of surgical medical technology and the improvement of people's aesthetic needs, traditional surgical methods have gradually developed to pursue smaller trauma and more precise surgery. minimally invasive surgery. [0003] As we all know, suturing is the basic condition to ensure good healing after surgery. During minimally invasive cardiothoracic surgery, it is often necessary to perform deep suturing on cut or pathologically fractured tissues and organs to restore their functions. Traditional open surgery requires an incision of more than ten centimeters, but ...
