Technical Field

The utility model relates to an operation expansion gear technical field, the concrete field is an incision expander is used in general surgery's operation.

Background

When a doctor performs a surgical operation on a patient, the doctor needs to pull the opening apart by using the expansion hook so as to obtain a wider operation visual field and clean tissues in a wound more conveniently. Generally, the hook body of the expansion hook for the surgical incision is narrow in transverse width, muscles on each side of the incision are pulled into a pointed triangle when the expansion hook is used, although the expansion amplitude of the incision along the transverse direction of a human body is large enough, the expansion amplitude of the incision along the longitudinal direction of the human body is relatively small, and the surgical visual field cannot be maximized. If the width of the body of the expansion hook is too wide, the expansion amplitude of the incision along the transverse direction of the human body is reduced, the contact surface between the expansion hook and the incision is increased, and the infection probability is improved; also, the length of a typical surgical expansion hook is not long enough to completely pull the pectoralis major muscle apart, thereby limiting the surgical field of view. Surgical procedures require the incision to be dilated using a dilating hook to expose the deep tissue. For the parts with abundant muscular tissues and more deep tissues, the surgical field is difficult to expose, and a plurality of assistants are generally needed for traction, so that the infection probability in the operation is increased. The expansion hook or the structure provided by the prior art is complex, and has more parts, which brings inconvenience to the cleaning and disinfection work of instruments; or simple structure, but need the assistant to carry out the tractive in the whole journey, not only the operation field exposes inadequately, and working strength is great moreover, leads to human fatigue easily, influences the operation and controls.
