Periosteum moving device

Abstract

The periosteum moving device is characterized in that the periosteum moving device comprises a capsular bag, and a hole is formed in the capsular bag; wherein the capsular bag is used for supporting the periosteum or the soft tissue, when gas or liquid is injected into the hole, the capsular bag can expand to move the periosteum or the soft tissue, in addition, the device further comprises a fluid control device, and the fluid control device can conduct gas charging and discharging control or liquid charging and discharging control on the capsular bag; according to the periosteum moving device, continuous, stable or slow traction force is provided when the periosteum or soft tissue is moved, so that the periosteum moving device is suitable for the periosteum or soft tissue moving operation, meanwhile, the periosteum or soft tissue can be integrally and evenly moved, and the periosteum moving device is easy and convenient to operate and low in cost. And the moving operation can be conveniently realized only by putting the bag under the periosteum or the soft tissue, and complicated operations such as injecting a bone needle are not needed, so that the operation of a doctor is greatly facilitated, the anesthesia time of a patient is shortened, and the related anesthesia risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a periosteum transfer device. Background technique [0002] Chronic refractory wounds refer to wounds with no healing tendency after at least one month of treatment. According to global estimates, the prevalence of chronic wounds is about 1% to 2%, and the prevalence is high in developing countries and people over the age of 65. At present, of the approximately 100 million wounds in China, such as skin, surgical incisions, and sinus tracts, approximately 30 million developed chronic and refractory wounds on the body surface. The etiological components of chronic wounds mainly include metabolic diseases (diabetes), trauma, infection and burns, tumors, and lower extremity vascular diseases. Among the metabolic diseases, the proportion of diabetes is increasing year by year. By 2008, the proportion of chronic wounds in domestic surveys was as high as 33.3%, whi...

Problems solved by technology

Chinese invention patent discloses a periosteum and soft tissue stretcher, application number: 202010831910.X, this kind of periosteum and soft tissue stretcher can not only be used for the treatment of periosteum transfer technology, but also can be used for microvascular network in ischemic parts In the place of reconstruction, the growth of blood vessels is stimulated by moving the periosteum; however, when the periosteum and soft tissue support piece needs to be placed under the periosteum when the periosteum and soft tissue distractor is used during the operation, the skin and periosteum block the support of the periosteum and soft tissue The "holes" on the slice require the doctor to drive bone needles into the holes of the periosteum and soft tissue support slices with the naked eye, and even the doctor may distort the bone needles if he is a little careless, which increases the difficulty of the operation

In addition: a Chinese invention patent discloses a periosteum transporter, application number: 202010347555.9, this type of periosteum transporter can not only be used for the treatment of periosteum transport technology, but also can be used for the place where the microvascular network needs to be reconstructed in the ischemic part. periosteum to stimulate the growth of blood vessels; however, the same problem exists. When the periosteum supporting sheet is placed under the periosteum during the operation, the skin and periosteum cover the "holes" on the periosteum and soft tissue supporting sheet. The "hole" on the periosteum support plate is drilled, and even if the doctor is a little careless, the bone needle will be distorted, which will increase the difficulty of the operation

It can be seen that in the above-mentioned invention patents, bone needles need to be driven in and operations such as "drilling holes on the corresponding periosteum support sheet" are required. This kind of periosteum removal operation has many "drilling holes", and the operation steps are complicated and difficult. Large incision incision and other factors make the operation difficult, slow postoperative recovery, and does not conform to the concept of minimally invasive surgery
