The utility model discloses a wound closing device, and belongs to the field of medical supplies. A skin pasting unit of the wound pulling and closing device comprises a skin surface flexible elastic pasting layer and a base band used for being fixedly connected with the wound pulling and closing unit, the base band is fixedly arranged on the side, close to a wound, of the upper surface of the skin surface flexible elastic pasting layer, and the outer edge of the base band does not exceed the outer edge area of the skin surface flexible elastic pasting layer; the base band on each skin pasting unit at least comprises a base band upper layer and a base band lower layer, the base band upper layer is composed of a plurality of base band upper layer substrates which are arranged at intervals in the long axis direction of the base band lower layer, and every two adjacent base band upper layer substrates are spaced or make contact with each other or are connected through an easy-to-tear structure. The fixed ends of the wound pulling and closing units located on the same skin pasting unit are connected to different upper-layer substrates of the base band, the lower layer of the base band is designed to be of an elastic sheet body structure with strip-shaped reinforcing ribs, and the wound pulling and closing device can be suitable for pulling and closing wounds on the joint part and the area near the joint.

The invention discloses a self-adhesive bandage for rapidly closing a wound and a preparation method of the self-adhesive bandage, and particularly relates to the technical field of high-molecular polymer bandings.The preparation method comprises the steps that an alpha, omega-dihydroxyl-terminated ethylene glycol polymer, cyclic oligosaccharide molecules and pure water are mixed, and a polymer solution I is obtained; mixing a cyclic oligosaccharide polymer, a polyether high-molecular compound and pure water to obtain a polymer solution II; mixing and drying the polymer solution I and the polymer solution II to prepare a thin film layer; dissolving a carboxylic acid compound and a protein compound in pure water, and heating to obtain an adhesion layer solution I; adding an ester compound and a keto acid compound into the adhesion layer solution I to obtain an adhesion layer solution II; uniformly dripping the adhesion layer solution II onto the thin film layer prepared in the step S2, and curing the adhesion layer solution II to obtain the bandage; the bandage is stretched, so that crystalline regions in the bandage are arranged in a highly oriented manner, the prepared bandage is high in contraction speed, and the modulus after contraction can be mechanically matched with various human tissues.

The utility model discloses a wound suture fixing device in an extubation tube, and relates to the technical field of wound suture, the wound suture fixing device in the extubation tube comprises a bottom plate, the top of the bottom plate is fixedly connected with a round rod, through the mutual cooperation of an operation table, a movable rod, a lactic acid nail and other components in the fixing device, when the lactic acid nail moves downwards, the lactic acid nail can be fixed on the round rod. According to the device, automatic operation can be achieved through the displacement plate and a related mechanical structure, manual intervention of medical staff in the tube drawing and suturing process is reduced, efficiency is improved, it can be guaranteed that the wound is accurately closed during tube drawing through the design of the lactic acid nails, and the wound is closed in the tube drawing process. The problems of irregularity and incomplete closure possibly caused by manual suture are reduced, so that a better healing effect is promoted, the time of medical operation can be remarkably saved through the automatic and simplified process, and the patient turnover rate is increased.

The preparation method comprises the following steps: S1, uniformly mixing prepared frankincense, calamine, calcined dragon bone, cacumen biotae, herba lycopi and rheum officinale, and crushing to obtain a mixture A; s2, sequentially grinding the mixture A obtained in the step S1 with talcum powder, minium and borneol in a sleeving manner, and uniformly mixing to obtain a mixture B; and S3, adding the mixture B obtained in the step S2 into molten liquid of vaseline and wool fat, and uniformly stirring to obtain the hemostatic paste. The blood-stopping ointment has the effects of healing sore and promoting tissue regeneration, cooling blood and stopping bleeding, clearing away heat and toxic materials, promoting blood circulation to subdue swelling, cooling blood and relieving pain, removing blood stasis and stimulating menstrual flow, and can achieve the treatment effect of getting twofold results with half the effort.

The utility model relates to the technical field of medical instruments, and discloses an anchor device for closing a wound notch in an endoscopic premature cancer dissection operation. The device comprises a spiral upper structure, a middle straight rod structure, a round separation blade, a rotatable middle column body and a bottom structure. The spiral upper structure is formed by spirally winding a metal wire, and the top end of the spiral upper structure is pointed cone-shaped; the middle straight rod structure is connected with the bottom end of the spiral upper structure; the round separation blade is arranged at the joint of the middle straight rod structure and the spiral upper structure; the rotatable middle column body is arranged on the middle straight rod structure in a sleeving manner, can rotate freely and is provided with a rope threading hole; the bottom structure is connected with the bottom end of the middle straight rod structure and comprises an upper wafer and a lower cube, and a circular groove is formed in the middle of the lower cube. Through the unique structural design, the efficiency and the reliability of closing the notch of the wound surface in the endoscopic premature cancer dissection operation are improved, and meanwhile, the convenience of the operation and the safety of a patient are both considered.
