Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, the medical operation wound expansion and fixing device in this embodiment includes a fixing plate 1, two brackets 2, two support blocks 3, two inclined guide blocks 4, a driving assembly, a crank handle 7, and a push ball 8 , two sleeve pipes 9, two fixed rods 10, two positioning tubes 11, two bolts 12, two limit blocks 14, two adsorption covers 15, two piston tubes 16 and two piston rods 17.

[0023] Two brackets 2 are symmetrically fixed on both sides of the bottom of the fixed plate 1 .

[0024] The two support blocks 3 are L-shaped and have two end surfaces perpendicular to each other, and the bends of the L-shape have right-angled chamfers to increase the mechanical strength of the support blocks 3 . The two support blocks 3 are arranged symmetrically, and one end faces of the two support blocks 3 are arra...

Abstract

The invention provides a wound pushing-open and fixing device for medical operations. Two brackets 2 are symmetrically fixed to two sides of the bottom of a fixing plate, two supporting blocks are respectively and rotatably connected with the two brackets, and a spring is fixedly connected between the bottoms of the two supporting blocks; two inclined guiding blocks are symmetrically and respectively fixed to two end oppositely-arranged surfaces of the two supporting blocks; and casing pipes are symmetrically and fixedly connected to two sides of the fixing plate, a fixing rod is inserted in each casing pipe, and an adsorption hood is fixedly connected to the bottom end of each fixing rod. The wound pushing-open and fixing device disclosed by the invention has the advantages that through the attraction of the adsorption hoods, the fixing device can be fixed to the skin of a patient or the surface of an operating table, and a threaded rod is rotated to drive a pushing ball to move downwards, so that a wound is pushed open; and a crank is in forward rotation or backward rotation, and the width of the wound pushed open by the supporting blocks can be adjusted.

Description

technical field [0001] The invention relates to the technical field of medical internal medicine, in particular to a wound stretching and fixing device for medical operations. Background technique [0002] After surgery, it is often necessary to cut an incision on the affected part of the patient in order to expose the diseased tissue under the skin surface of the affected part to facilitate the operation. After incision, the wound needs to be stretched and fixed to obtain a clearer view. Surgical field of view, improve the accuracy of surgery. In the prior art, the surgical forceps are usually used to open the wound, and then the medical staff hold the surgical forceps to fix it. This fixing method is time-consuming and laborious. After a long time, it will cause the hand muscles of the medical staff to fatigue, thus affecting the fixation. stability, and it is inconvenient to adjust the depth and width of the opening of the wound, thereby affecting the efficiency and accu...
