Embodiment 1

[0040] Such as Figure 1 to Figure 12 As shown, a bone moving device includes a first bone needle 1, a second bone needle 2 and a lifting device, the second bone needle 2 is hollow and is set on the first bone needle 1, and the first bone needle The needle 1 is connected to the second bone needle 2 through the lifting device, and the second bone needle 2 is hollow and covered with the first bone needle 1, so that when the first bone needle 1 and the second bone needle 2 penetrate into the bone 52, the bone 52, only one wound is needed to realize the removal operation, and the materials of the first spicule 1 and the second spicule 2 are titanium alloy.

[0041] In order to facilitate the lifting device to move up and down on the first bone needle 1, the first end of the first bone needle 1 is provided with a first thread 11, and the lifting device is in order to facilitate the connection of the second bone needle 2. The first end of the second bone needle 2 is provided with a...

Abstract

The invention discloses a bone transport device. The bone transport device is characterized by comprising a first bone needle, a second bone needle and a lifting device, wherein the second bone needle is hollow and sleeves the first bone needle, and the first bone needle is connected with the second bone needle through the lifting device. According to the bone transport device, two bone needles can be punched into one wound, so the wound formed by punching the bone needles is greatly reduced; a transport speed is high, bone transport can be achieved only by rotating a rotating ring, transport time is at least one time shorter than transport time needed by a traditional bone transport device, and the bone transport device has the function of being easy and convenient to operate; and compared with a traditional bone transport device, the bone transport device of the invention has the advantages that fewer parts are used, the bone transport device is more convenient to assemble, and less operation time is needed.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a bone moving device. 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 skin, surgical incision and sinus wounds in China, about 30 million have developed 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 33.3%, has become the main cause of ...
