Parallel surgical spreader

Abstract

The invention relates to a medical appliance, in particular to a parallel surgical spreader which comprises parallel handles, pulleys, sliding chutes, stretching handles, a rotating shaft, an annular holder and clamp handles, wherein the two parallel handles which are parallel to each other are positioned at the left and right sides of an X-shaped frame formed by the two stretching handles, and the pulleys at the end parts of the two stretching handles are respectively positioned in the sliding chute of the parallel handle on the same side and can freely slide along the sliding chute. The pulleys at the lower ends of the two stretching handles are respectively connected with one end of the two clamp handles and are in rotating movable fit, the shaft is arranged at the intersection of the two clamp handles, and the two clamp handles are connected with the shaft and are in rotating movable fit with the shaft. The invention realizes that the incision can be pulled under the condition that the parallel handles are parallel to each other, thereby greatly widening the surgical field and improving the surgical quality compared with the prior art.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a parallel operation spreader. Background technique [0002] During surgery, a well-exposed surgical field of view is crucial to any surgical procedure. At present, hand-type retractors are the most commonly used for exposing instruments in surgery. When pulling with retractors, since the retractors are mostly in point contact with the edge of the surgical incision, usually each retractor can only pull out a triangular surgical field of view. In order to achieve a wider surgical field of view, it is necessary for multiple hands to simultaneously pull multiple points on the edge of the surgical incision with multiple retractors, but such an operation is time-consuming, laborious, and very inconvenient. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a parallel surgical spreader that can obtain a wide surgical field of...
