Problems solved by technology

However, in the existing operation of tibial transverse bone transfer technology, it is necessary to drill a hole on the tibia, cut off the bone block and then use the support to move the tibia. Drilling, osteotomy, and transfer on the tibia or bone increase the risk of surgery, while minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. If the tibial transverse bone transfer operation can be miniaturized and miniaturized It will bring good news to patients. The inventor found a new surgical method through research, which can not only achieve the effect of tibial transverse bone transfer technology to treat diabetic feet, but also realize the miniaturization of surgery, but there is no related medical equipment at present. to stretch the periosteum and soft tissue

Embodiment 1

[0033] Such as Figure 1 to Figure 4 As shown, a kind of periosteum and soft tissue stretcher, comprises periosteum and soft tissue supporting plate 1 and lifting device, and described periosteum and soft tissue supporting plate 1 is provided with a threaded hole 1 and lifting device, and lifting device comprises bone needle 2 and rotating Sleeve 3, the rotating sleeve 3 is set on the bone needle 2 and one end is provided with an external thread 31, the external thread 31 cooperates with the threaded hole 1, when the rotating sleeve 3 is rotated, the periosteum and soft tissue support The sheet 1 can move along the axial direction of the spicule 2, and the periosteum and soft tissue supporting sheet 1 is used to support the periosteum and soft tissue.

[0034] In order to realize automatic rotation, the described periosteum and soft tissue stretcher also includes an automatic rotation device, the automatic rotation device includes a motor 4 and a control system, the motor 4 is...

Embodiment 2

[0041] Such as Figure 5 to Figure 6Shown, a kind of periosteum and soft tissue stretcher, comprises periosteum and soft tissue supporting plate 1 and lifting device, described periosteum and soft tissue supporting plate 1 is provided with a threaded hole 1 and lifting device, and lifting device comprises bone needle 2 and Rotation sleeve 3, the rotation sleeve 3 is set on the bone needle 2 and one end is provided with an external thread 31, the external thread 31 cooperates with the threaded hole 1, when the rotation sleeve 3 is rotated, the periosteum and soft tissue The support piece 1 can move along the axial direction of the bone needle 2, and the periosteum and soft tissue support piece 1 is used to support the periosteum or soft tissue.

[0042] working principle:

[0043] First cut an incision on the skin, put the periosteum and soft tissue supporting sheet 1 under the periosteum (the position between the periosteum and the bone) or under the soft tissue, and then dri...

Embodiment 3

[0045] Such as Figure 4 , Figure 7 to Figure 9 Shown, a kind of periosteum and soft tissue stretcher comprises periosteum and soft tissue supporting plate 1 and lifting device, described periosteum and soft tissue supporting plate 1 is provided with two threaded holes 1 and two lifting devices, and each lifting device includes The bone needle 2 and the rotating sleeve 3, the rotating sleeve 3 is set on the bone needle 2 and one end is provided with an external thread 31, the external thread 31 is matched with the threaded hole 1, when the rotating sleeve 3 is rotated, the The periosteum and soft tissue supporting sheet 1 can move along the axial direction of the bone needle 2, and the periosteum and soft tissue supporting sheet 1 is used to support the periosteum or soft tissue. Two lifting devices are used to make the periosteum and soft tissue supporting sheet 1 It is more stable in the process of moving up and down without deflection.

[0046] In order to realize automa...

Abstract

The invention relates to a periosteum and parenchyma distractor. The periosteum and parenchyma distractor is characterized by comprising a periosteum and parenchyma support sheet and lifting devices,wherein one or more thread holes and lifting devices are arranged on the periosteum and parenchyma support sheet; and each lifting device comprises a spicule and a rotary sleeve, wherein the rotary sleeve sleeves the spicule, an external thread is formed in one end of the rotary sleeve, the external thread cooperates with the corresponding thread hole, when the rotary sleeve rotates, the periosteum and parenchyma support sheet can move along the axial direction of the spicule, and the periosteum and parenchyma support sheet is use for supporting periosteum. The periosteum and parenchyma distractor can slowly and automatically distract periosteum and parenchyma. The periosteum and the parenchyma are slowly distracted to enable proliferation and biosynthesis functions of cells to be stimulated. The self repair capacity of organisms is mobilized, the foot blood supply can be improved, and the ulcer healing can be promoted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a stretcher for periosteum and soft tissue. Background technique [0002] Chronic non-healing wounds refer to wounds that have no tendency to heal after treatment for at least 1 month. According to global estimates, the prevalence of chronic wounds is about 1% to 2%, and the prevalence is higher in developing countries and people over 65 years old. At present, among the approximately 100 million person-times of skin, surgical incision and sinus wounds in China, about 30 million person-times develop into chronic refractory wounds on the body surface. The etiology of chronic wounds mainly includes metabolic diseases (diabetes), trauma, infection and burns, tumors, and vascular diseases of the lower extremities. Among them, the proportion of diabetes in metabolic diseases is increasing year by year. By 2008, the etiology of chronic wounds in domestic surveys was as high as ...
