The utility model discloses an intramedullary needle for treating fracture and convenient to hold, which is provided with a treatment section and a holding section for operating and holding, and a positioning structure for holding and positioning is further arranged on the holding section. The intramedullary needle conforms to tubular bone biological fixation, the treatment section can be effectively prevented from rotating in the surgical treatment operation process through the holding section, the penetration depth and path of the treatment section can be further accurately controlled, the treatment accuracy is improved, and the treatment duration is shortened. When the intramedullary needle is used in the treatment process of metacarpal bone fracture, further damage to fracture local hematoma and periosteum can be avoided through closed reduction, blood supply of sclerotin is protected, and fracture healing is facilitated. The intramedullary needle is small in trauma, small in wound scar and beneficial to attractiveness; intramedullary fixation retains the minimally invasive characteristic of kirschner wire fixation, and the fixing effect is more stable and lasting than that of a kirschner wire, and the articular surface is not damaged.

The invention discloses application of hydrogel in preparation of an external preparation for treating wound scar infection risk, and belongs to the technical field of biomedical materials. The preparation method of the hydrogel comprises the following steps: preparing a copper ion solution with the mass fraction of 0.01%-0.05%, adding 0.1%-1% of sodium alginate into every 100 mL of the copper ion solution according to the mass fraction, adjusting the pH value to 4.5-5.5, and carrying out defoaming and sterile treatment to obtain the hydrogel capable of regulating and controlling the collagen proportion and reducing the risk of wound scar infection. According to the invention, a'regeneration type 'mode with a better healing guide structure and higher softness is adopted, so that the risks of hypertrophic scars, skin sclerosis and hardening after wound healing caused by fungal infection and the like are obviously reduced from the source. The application is suitable for high-quality repair of chronic wounds of human and pets.
