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.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a hydrophilic drainage layer, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for an organ protection layer, as well as a system for the treatment of abdominal wounds.

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 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. The laparoscopic tissue spreader comprises a support mechanism and a spreading mechanism, the support frame comprises a support frame, a first support plate and a second support plate, and the first support plate and the second support plate are respectively mounted on opposite sides of the support frame; the spreading mechanism includes a clamping member and a driving member, and the clamping member is detachably connected to the support frame to send the support mechanism to a supporting position or take the support mechanism away froma supporting position. The driving member is cooperated with the support frame to move the first support plate away from or toward the second support plate. The support mechanism of the laparoscopic tissue spreader is spread as a frame structure, the first support plate and the second support plate are used to open the patient's tissue, the support frame takes up a small space, a surgical instrument can pass through the support frame for operation, and re-opening of the micro wound can be avoided, which reduces the abdominal wound of the patient and the surgical pain of the patient.
