Row hook type skin stretch closure device

Abstract

The invention provides a row hook type skin stretch closure device. The row hook type skin stretch closure device comprises adjusting assemblies and fixing hook devices, wherein each adjusting assembly comprises a threaded rod, a pressure adjusting member, a pressure adjusting spring, a sliding casing pipe and a fixing nut, each fixing hook device comprises a fixing hook body part and multiple hooks arranged on the corresponding fixing hook body part, the upper portions of the fixing hook body parts are transversely provided with circular holes, each fixing nut and the corresponding pressure adjusting member are rotationally arranged at the two ends of the corresponding threaded rod respectively, each pressure adjusting spring and the corresponding sliding casing pipe sequentially sleeve the corresponding threaded rod, each pressure adjusting member, the corresponding pressure adjusting spring and the corresponding sliding casing pipe are in pushing cooperation in sequence, each threaded rod between the corresponding sliding casing pipe and fixing nut is sleeved with an inner sleeve and an outer sleeve, each outer sleeve sleeves the corresponding inner sleeve, the two fixing hook devices slidably sleeve the inner sleeves through the circular holes and are in pushing cooperation with the outer sleeves and the fixing nuts in the axial direction respectively, and the outer sleevesare in pushing cooperation with the sliding casing pipes; or the inner sleeves are not arranged, and the middles of the threaded rods are provided with smooth rod sections, thereby ensuring that therow hook type skin stretch closure device cannot be jammed when the fixing hook devices slide.

Description

technical field [0001] The invention relates to the technical field of trauma surgical instruments, in particular to a row hook type skin stretch closure device. Background technique [0002] Skin defects caused by trauma are relatively common in clinical practice, and are often repaired by skin grafting or skin flaps. However, such methods will damage another donor site of the patient. Skin stretch surgery is an effective method for the treatment of skin defects. It is through continuous mechanical tension acting on the skin and soft tissue to promote skin tissue and cell division, proliferation, growth, increase of intercellular space and increase of inherent elasticity, so as to obtain "extra" intact skin and soft tissue and close the wound. Skin stretch surgery has the advantages of rapid wound closure, simple operation, and few complications. It is a method for the self-repair of soft tissue defects. Skin stretch surgery requires special traction devices (ie, skin stret...
