Abstract

The invention discloses an incision distractor for surgery. The incision distractor comprises an elastic opening and closing assembly; the elastic opening and closing assembly includes two supportingrods, two sets of connecting sheets and a torsion spring; the connecting pieces are fixedly connected with ends of the supporting rods; a pin shaft is rotatably connected between the connecting sheetsin an inserted manner; a torsion spring is connected onto the pin shaft in a sleeving manner; two ends of the torsion spring are attached to surfaces of inner sides of the two supporting rods respectively; threaded holes are formed in one side of each supporting rod; a connecting assembly includes two sleeves and locking screws; each sleeve is connected with the end of the corresponding supporting rod in a sleeving manner; the locking screws are arranged by multiple groups; the locking screws penetrate through the surface of one side of each sleeve in a screw connection manner; and one end ofeach locking screws is rotatably connected with the corresponding threaded hole in an inserted manner. According to the incision distractor, by installing the elastic opening and closing assembly, the problem that an additional assistant needs to perform manual distraction, and mechanical distraction is conducted on an incision, and thus, secondary hurt is likely to cause to soft tissues is solved.

Description

technical field [0001] The invention relates to the technical field of medical machinery, in particular to an incision spreader for surgery. Background technique [0002] The gap needs to be fully exposed during the surgical operation, but the traditional retractor has the following defects: first, additional assistants are required for manual traction, and second, mechanical traction on the incision is easy to cause secondary damage to soft components. Contents of the invention [0003] (1) Technical problems to be solved [0004] The present invention can solve the existing problem that additional assistants are required to manually pull, mechanically pull the incision, and easily cause secondary damage to soft components. [0005] (2) Technical solution [0006] In order to achieve the above object, the present invention adopts the following technical solutions, a surgical incision spreader, comprising: [0007] An elastic opening and closing assembly, the elastic op...
