Example Embodiment

[0041] Example 1

[0042] An assembled multi-section retractable skin distractor, suitable for 8 defective skins. When skin extension is used for treatment, according to the length and width of the patient's skin injury, the longer and opposite sides of the skin 8 are defined as longitudinal, spanning The direction on both sides of the vertical is horizontal.

[0043] Such as figure 1 As shown, the distractor includes two distractors 7 arranged on the longitudinal sides of the defect skin 8 to fix the edges of the defect skin 8 for passing through the skin; the distraction parts 7 are bones that can pass through the skin. Round needles, different shapes of bone round needles can be used according to the different shapes of the patient’s wound, such as straight, arc or wavy. After the bone round needles pass through the skin alternately up and down, the two ends of the bone round needles are kept 2~4cm each Bare outside the skin; preferably, the bone round needle is made of sterile...

Example Embodiment

[0056] Example 2

[0057] The difference between this embodiment and embodiment 1 is that the adjusting part includes two distraction bases 1, two connecting parts arranged at the lower part of the distraction base 1, 2, and a laterally spanning between the defective skin 8 The adjusting rod 3, an adjusting device 4 arranged at one end of the adjusting rod 3, and a connecting handle 6 arranged on the upper part of the stretching base 1.

[0058] The connecting handle 6 and the vertical side of the L-shaped stretch base 1 are interference fit, that is, a rubber ring is fixed on the outside of the connecting handle 6 and pressed into the vertical side of the L-shaped stretch base 1.

[0059] The adjustment structure 4 includes a sleeve 41 and a tightening member 42, and the sleeve 41 is directly fixed on another stretch base 1.

[0060] The use process of the distractor in this embodiment is as follows:

[0061] When the patient needs to use skin stretching for treatment, according to th...

Abstract

The invention relates to the field of medical instruments, in particular to an assembled multi-section telescopic skin retractor. The assembled multi-section telescopic skin retractor is suitable forbeing fixed to the defect skin and closing the wound surface by means of traction force with certain strength. The device comprises two traction parts penetrating through the two longitudinal sides ofthe defect skin respectively and two adjusting parts used for adjusting the distance between the traction parts. Each adjusting part comprises (1) two traction bases located on the edge of the defectskin, two connecting parts arranged on the traction bases and used for fixing the traction parts, (2) a transverse adjusting rod arranged on the two traction bases and crossing the defect skin and anadjusting device arranged at one end of the adjusting rod and used for adjusting the effective length of the adjusting rod. The skin retractor is simple in structure and easy to install, the stretching amount of the skin near the soft tissue defect position of a patient can be accurately adjusted, and the operation process is simple, convenient and easy to implement; all the components of the device are located around the wound surface of the patient, the wound surface cannot be shielded, and the change of the wound surface and the tissue around the wound surface can be conveniently and directly observed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an assembled multi-section retractable skin stretcher. Background technique [0002] In medicine, soft tissue wounds that cannot be directly sutured due to trauma, infection, donor site after flap removal, incision of fascial compartment syndrome, excision of body surface tumors, and chronic medical diseases are extremely common. The traditional treatment method is to change the dressing after debridement, and then perform skin grafting or skin flap transplantation to close the wound after the wound is clean and the granulation tissue grows well. However, traditional skin grafting and skin flap transplantation may cause complications such as infection of the donor site, vascular crisis, poor wear resistance of the skin in the recipient area, long wound healing time, and scar formation that affect the appearance and limb function. [0003] There are many repair methods for skin def...
