An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.

An integrated bandaging system for encircling the abdomen of a horse. A ventral access opening selectively provides access to the horse's abdomen while the bandage remains in place. This ventral access opening is normally covered by a ventral window cover. However, the window cover may be easily opened so that an old dressing can be removed, an abdominal wound can be cleaned, and a new dressing applied. The invention has four major components: a main wrap, a saddle bridge, a ventral window cover, and a brace. The main wrap is easily placed around the horse's abdomen and secured using VELCRO® fasteners. It includes the ventral access opening. The saddle bridge attaches over the top of the main wrap and adjustably applies tension to the horse's mid section. The ventral window cover attaches over the ventral access opening and provides further adjustment of the tension on the abdomen. The brace applies over the points of the horse's shoulders, between the front legs, and over the ventral chest region. This final component prevents the bandage from slipping aft on the horse.

An intra-abdominal organ suspension device is used in conjunction with at least two fixers located outside the patient's body to suspend a specific organ during an operation. The intra-abdominal organ suspension device includes a The receiving part, at least one connecting part connected to the receiving part, and at least two positioning parts respectively connected to both sides of the connecting part and passing through the abdominal wall of the patient's abdominal cavity, and after the positioning part passes through the abdominal wall, it is composed of The connecting piece pulls up the receiving piece, and the fixing piece is clamped and fixed on the connecting piece partially exposed outside the patient's body, so that the specific organ is suspended and positioned. By virtue of the fact that the locating piece directly penetrates the abdominal wall from the abdominal cavity, and is clamped and fixed by the fixing piece, there is no need to open an opening for each locating piece to pass through, so the number of abdominal wounds of the patient can be reduced, thereby reducing the number of surgical procedures for the patient. Postoperative pain and wound recovery time.

The present invention relates to a bandage for use in negative-pressure wound therapy, more particularly for wounds in the abdominal region, comprising a flexible film as a wound contact layer and at least one conduit applied to the film, wherein the conduit communicates with the wound space through openings in the conduit and in the film.

The invention discloses an umbrella type anastomat for a laparoscope. The umbrella type anastomat comprises a regulating mechanism, a first supporting mechanism, a second supporting mechanism and a fixed shell body, wherein the regulating mechanism is arranged at one end of the fixed shell body, the first supporting mechanism and the second supporting mechanism are arranged at one end, far away from the regulating mechanism, of the fixed shell body, the regulating mechanism is composed of the fixed shell body, an adjusting handwheel, a cutting control handle, an interlocking lever, a control switch, an adjusting threaded hole, a center rod, a limiting groove and a limiting block, the center rod is connected inside the fixed shell body in a sliding manner, and one end of the fixed shell body is rotatably connected with the adjusting handwheel. The umbrella type anastomat for the laparoscope, disclosed by the invention, is compact in structure, and linear-circular conversion of the anastomat is achieved by using an umbrella rod of an umbrella cover structure; a circular anastomosing method is carried out under a laparoscope, operations are completely the same as laparotomy operations, a small space of a puncture hole of the laparoscope is broken through, circular anastomosing under the laparoscope is achieved, and a wound of an abdominal region is minimally invasive; and meanwhile, secondary injuries caused by other anastomosing methods are avoided, the time of surgical operation is shortened, and wound healing is facilitated.

The invention relates to a bionic peritoneum for open treatment and repair of the abdominal cavity and a preparation method thereof, comprising hydrogel, polylactic acid-glycolic acid microspheres mounted on the hydrogel, and polylactic acid microspheres covered on the hydrogel and polylactic acid -Nanofibrous membrane on glycolic acid microspheres, by loading polylactic acid-glycolic acid microspheres on the hydrogel, the microspheres are the source of growth factors required for wound repair, and covered with a nanofiber membrane to form a double-layer membrane structure, constructing "artificial bionic peritoneum" applied to open wounds in the abdominal cavity; bionic peritoneum can not only protect the intestines, but also serve as a carrier for controlled-release microspheres, organically combine wound protection and drug release functions, and participate in wound repair; bionic peritoneum may be through the following mechanisms Promote healing, differentiate and participate in the formation of new tissue, or paracrine cytokines to promote the formation of new tissue; the synergistic effect of artificial peritoneum and microspheres, while directly participating in the regeneration of defective tissue, can mobilize the body's own regeneration and repair mechanism, and finally Realize rapid repair of open wounds in the abdominal cavity.

The invention discloses an auxiliary incision-free anus cannula device, relates to a peritoneoscope surgical operation auxiliary instrument and provides an auxiliary incision-free anus cannula device which has the advantages that no scar is left on the abdomen, the postoperative pain is reduced to the greatest extent, the length of stay is shortened, the expense is reduced and the like. The auxiliary incision-free anus cannula device is provided with an outer cannula, a guide tube, a rear cover and an apparatus hole cover, wherein external threads are formed at the tail end of the outer cannula; the outer cannula sleeves the guide tube; internal threads which are formed at the rear cover are in threaded connection with the external threads at the tail end of the outer cannula; a conical part is arranged at the front end of the guide tube; a grip handle is arranged at the rear end of the guide tube; an apparatus hole is formed in the tail of the rear cover; internal threads at the apparatus hole cover are in threaded connection with external threads at the tail of the rear cover. A peritoneoscope lower left colon and rectum resection operation is completed without an abdomen wall auxiliary incision, the minimally invasive aim is achieved, an abdomen wound is more attractive, the occurrence of postoperative incisional hernia, incision infection, dehiscence, incision tumour abdomen wall plantation and the like is avoided, and the intestinal canal adhesion probability is reduced. The auxiliary incision-free anus cannula device has the advantages that tumour-free operation is realized, the operation is simple and convenient, and safety and reliability are realized.

The invention discloses a laparoscopic tissue spreader.
