Problems solved by technology

There are many types of existing skin stretchers, but some stretchers are bulky, not minimally invasive in use, difficult to install, and not comfortable to wear; stretch belts of some skin stretchers, The design of the pulling carrier at the connection between the steel wire or the Kirschner wire and the skin at the wound margin is still unsatisfactory and cannot meet the needs of wounds of different shapes; some skin stretching devices, especially skin stretching belts, have insufficient biomechanical strength, and Poor reliability, easy to break during use, or cut the skin at the wound edge; some stretchers cannot achieve precise stretching, that is, the adjustment method is relatively extensive; the various shortcomings of the stretcher for skin stretching mentioned above limit the stretching of the skin wide range of clinical applications

Embodiment 1

[0042] An assembled multi-section retractable skin stretcher, suitable for 8 defected skins. When skin stretching is used for treatment, according to the length and width of the patient's skin damage, the longer opposite sides of the defected skin 8 are defined as the longitudinal direction, spanning The orientation of the vertical sides is landscape.

[0043] Such as figure 1 As shown, the stretcher includes two stretching parts 7 arranged on the longitudinal sides of the defective skin 8 to fix the edge of the defective skin 8 for passing through the skin; the stretching part 7 is a bone that can pass through the skin For circular needles, different shapes of bone needles can be used according to the different shapes of patients’ wounds, such as straight line, arc or wave shape. After the bone needles pass through the skin alternately up and down, keep 2-4cm at both ends of the bone needles. It is exposed outside the skin; preferably, the bone circular needle is made of ste...

Embodiment 2

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

[0058] The connecting handle 6 is an interference fit with the vertical side of the L-shaped stretching base 1 , that is, the rubber ring is fixed outside the connecting handle 6 and pressed into the vertical side of the L-shaped stretching 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 process of using the retractor in the present embodiment is as follows:

[0061] When the patient needs to be treated with skin stretching, according to the shape ...

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...
