Example Embodiment

[0023] Example 1: see Figure 1 to Figure 5 The shown automatic retractor for soft tissue debridement includes a fixed sleeve 4 with a rectangular cross-section. The upper and lower sides of the fixed sleeve are provided with corresponding pin holes 4-1 with equal diameters; two elastic strips 3 with the same structure Seven length adjustment holes 3-1 at equal distances are respectively provided on one end of the, and the diameter of the length adjustment holes is equal to the pin hole 4-1 on the fixing sleeve 4; the other end of the two elastic strips 3 The parts are all inclined upward, the inclined angle α is 120 degrees, and a hook seat 3-2 is respectively provided on the upward inclined surface;

[0024] The two elastic strips 3 are provided with a plurality of equidistant length adjustment holes 3-1. The ends are inserted into the fixing sleeve 4 and overlap each other, and there are at least one pair of length adjustment holes 3-1 and the upper and lower sides of the fixi...

Example Embodiment

[0028] Embodiment 2: Two elastic strips 3 with the same structure are respectively provided with two equidistant length adjustment holes 3-1 on one end, and the other ends of the two elastic strips 3 are both inclined upwards. The angle α is 100 degrees; the rest is the same as the first embodiment.

Example Embodiment

[0029] Embodiment 3: Two elastic strips 3 with the same structure are respectively provided with five equidistant length adjustment holes 3-1 on one end, and the other ends of the two elastic strips 3 are both inclined upwards and inclined The angle α is 110 degrees; the rest is the same as the first embodiment.

Abstract

The invention relates to a soft tissue debridement self-retaining retractor, comprising a fixed bushing, wherein pin holes are arranged in the fixed bushing, a plurality of length adjusting holes with equal intervals are arranged in one end of each of two elastic elongated sheets with the same structure, and the aperture of each length adjusting hole is equal to the aperture of each pin hole in the fixed bushing; the other end of each of the two elastic elongated sheets tilts upwards, and one hook body seat is respectively arranged on each upward-sloping surface; the ends, provided with the length adjusting holes with equal intervals, of the two elastic elongated sheets are relatively inserted into the fixed bushing to be superposed mutually, and at least one pair of length adjusting holes align to the pin holes in the upper and lower surfaces of the fixed bushing; a plug pin is inserted into the pin holes in the fixed bushing to connect the two elastic elongated sheets to the fixed bushing; and two hook bodies with the same structure are fixedly connected with the hook body seats on the other ends of the two elastic elongated sheets through nuts respectively. The soft tissue debridement self-retaining retractor is convenient to carry, prolongs or shortens adaptively according to the length of a debridement incision, better exposes the surface of a wound, facilitates the debridement operative procedures, is rapid to combine, simple and convenient to adjust, large in application range, and reliable in traction and separation and a doctor does not need the assistance of an assistant.

Description

technical field [0001] The invention relates to a field surgical medical instrument, in particular to an automatic retractor for soft tissue debridement suitable for firearm injuries. Background technique [0002] Experience in the treatment of war wounds in previous wars shows that for soft tissue injuries caused by firearms, debridement surgery must be performed urgently in the shortest possible time, that is, to use surgical methods to remove foreign bodies in open wounds, and to remove necrotic, inactivated or heavily contaminated tissues. Tissues, correct treatment of damaged blood vessels and nerves. The principles of debridement for soft tissue gunshot wounds are: (1) The sooner the debridement after injury, the better; (2) Strict aseptic operation; (3) The incision should be large enough and the debridement should be thorough; (4) The wound should not be debrided after debridement Primary suture. Although debridement of soft tissue gunshot wounds has been extensive...
