The invention discloses a protecting and fixing device for wound, comprising at least one protecting and fixing layer with openings, wherein the protecting and fixing layer with openings is longitudinally provided with an opening for communicating the upper end face and the lower end face; the opening can enclose the wound therein so as to make the protecting and fixing layer with openings limit the wound tension and increase the mobile corrugation of the wounded skin. The invention can protect and fix the operation wound, the trauma wound or the catheter infusion wound into an opening which can limit the tension increase of the wound and the mobile corrugation of the surface skin of the wound and can prevent the wound from being torn and cracked and also avoid the damage for the wound due to the mobile corrugation and the surgical dressing of the wounded skin as well as the relative displacement frictions of the infusion catheter. Therefore, the invention fills the blank of current technology, which can enable the covered dressings to penetratively contact the secretion so as to absorb the exudate of the wound. Besides, the invention can prevent the foreign material contact anaphylaxis due to the wound contacting by compressing the dressing and the direct bonding of the catheter infusion wound and can prevent the re-injury of the wound caused by the synechia between the dressing and the wound secretion.

The invention relates to a degradable backflow-prevention esophagastro anastomosis support, relates to a hollow or tubular prosthesis capable of being implanted in vivo, and particularly relates to a degradable backflow-prevention support used for esophagastro anastomosis. The degradable backflow-prevention esophagastro anastomosis support comprises a tubular support body made of a degradable material; and a backflow-prevention device capable of isolating objects contained in an esophagastro and an anastomosis opening is arranged inside the tubular support body. The esophagastro anastomosis support is provided with a detachable inner core penetrating an inner hole of the tubular support body; the esophagus end of the detachable inner core is hemi-ellipsoidal and extends out from the inner hole of the tubular support body; the stomach end of the detachable inner core is conic; grooves capable of being clamped through vessel clamps are formed in the two sides; and annular sunken ligation grooves are formed in the surface of the periphery of the tubular support body. In an esophagastro anastomosis operation, the detachable inner core can be used for clamping operation, and depending on the supporting function of the support body and the positioning function of the ligation grooves, the operation is convenient, simple and rapid; and the support is not high in material price, the manufacturing process is simple, the operation cost can be obviously reduced, and the loads of a patient are reduced.

Disclosed is a bile duct anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The stent main body takes the shape of a tube and has a diameter which is suitable for putting in a bile duct. Each of the two sides of the outer surface of the main body is provided with a circle of protuberance for fixing the pouch line knots at the broken ends of the bile duct. The bile duct anastomosis stent has the advantages that the bile duct anastomosis stent is easy to operate, quick, short in anastomosis time and low in cost and has no complicating disease after the operation.

The invention relates to a gastrointestinal anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The middle of the stent main body is tubular, and two ends of the stent main body are open and increase gradually like a trumpet; one opening is big and the other opening is small; the opening at the big end is in a shape and a size which are suitable for the lumen of the stomach; and the opening at the small end is in a shape and a size which are suitable for the lumen of the intestine. The gastrointestinal anastomosis stent can simplify anastomosis process, shorten anastomosis time and reduce complicating diseases after the operation, and the stend is low in cost and wide in application range.

The invention relates to an iliac screw with a bone induction material coating and a spine fixing device. The iliac screw comprises a screw body and a connector; the screw body comprises a rod portion and a head portion located at one end of the rod portion, at least a part of the surface of the rod portion is provided with an outer thread, and the surface of the outer thread is coated with a bone induction material layer; the connector is used for fixedly connecting the head portion with a spinal rod. According to the iliac screw and the spine fixing device, on one hand, the osteogenesis capacity can be excited by utilizing the bioactivity of a bone induction material to promote bone tissue growing and healing, and close combination can be formed between the screw body and bone tissue to ensure the connection reliability; on the other hand, due to the fact that the iliac screw is coated with the bone induction material, the screw body can be prevented from directly making contact with the bone tissue, and the problems such as infection are prevented from being generated.

The invention relates to collagen gel as well as a preparation method and application thereof, and belongs to the technical field of medical cosmetology. The collagen gel provided by the invention comprises collagen, hyaluronic acid, a cross-linking agent and a vascular endothelial cell growth factor. The collagen generated by fibroblasts is used as a raw material, the hyaluronic acid and the cross-linking agent are mixed to prepare a gel product, and the autologous collagen gel is free of toxic and side effects, has good biocompatibility and histocompatibility, can be used as an organism tissue filler in medical cosmetology. Wherein the vascular endothelial cell growth factor can promote healing and growth of subcutaneous blood vessels after filling, promote blood circulation, moisten skin, eliminate wrinkles and prevent stains, and has a very good beautifying effect.

The invention discloses a colon ligature anastomosis stent which comprises a bypass pipe made from degradable material that is acceptable to the human body; the middle part of the bypass pipe is tubiform, and the two ends of the bypass pipe are respectively provided with a widening funnel-shaped opening; a groove is arranged in a connection section in which the tubiform middle part is connected with the funnel-shaped opening. During the anastomosis, the stent is put in an intestinal cavity, and colon is fixed on the stent by a wire at the groove; the two ends of the colon are in contact with each other in the centre of the vertical axis of the stent, grow and heal, thus realizing the anastomosis of the colon. The colon ligature anastomosis stent can simplify the operation, shorten the operation time and reduce the incidence rate of anastomotic leakage and anastomotic stenosis.
