The invention discloses a rapid scar-free healing device for limb and face sutured wounds. The rapid scar-free healing device comprises a supporting plate, a threaded bushing, a sliding column, an adjusting rod, a pressure bolt, a pan head pull rod, a push plate, a pressing plate, a breathable plate, a limiting pin, a tension spring, a hanging rod and a fastening belt. Through the retraction force of the tension spring, the push plate extrudes tissues on the two sides of a sutured wound to bulge towards the middle, and tissue tension is changed into tissue tightening force; the pressing plate and the breathable plate are pushed to move downwards through the pressure bolt, the protruding portion of the wound is wedged and flattened, tissues on the two sides of the wound are tightly attached in an airtight level, the butt joint and anastomosis speed of the tissues is increased, microorganisms can be effectively prevented from invading the wound, and infection is prevented. By flattening and suturing the convex part of the wound, the forced tissue hyperplasia can only be carried out subcutaneously, the body surface is always kept in a flat, smooth and non-hyperplasia state, and the sutured wound can be quickly healed without scars; the vertical pressure of the pressing plate and the transverse pushing force of the pushing plate can be steplessly adjusted through the pressure bolt and the adjusting rod so as to adapt to the tolerance of a patient.

In a dental implant surgery, bone grafting is needed due to insufficient bone mass, and periosteum tension reduction is needed during bone grafting, so that the minimally invasive periosteum tension reduction device is an instrument for periosteum minimally invasive tension reduction during dental implant, and aims to reduce the pain of a patient during periosteum tension reduction during implant and improve the operation convenience of a doctor. In the current oral implant surgery, the existing implant periosteum distension reduction instrument is only provided with a surgical blade clinically at present, and a doctor needs to add a vertical incision in the periosteum distension reduction process, so that the pain of a patient is greatly increased, the operation time of the doctor is greatly prolonged, and the operation difficulty of the doctor is also increased. According to the minimally invasive periosteum tension reducing instrument for oral implantation, vertical incisions of an implantation area are reduced, the direction and the movement track of a traditional scalpel are changed, the minimally invasive purpose is achieved, and the consequences that the vertical incisions of gingival mucosa are increased by the traditional scalpel and the soft tissue of a patient is excessively injured due to too deep cutting of the traditional scalpel are not brought to a doctor; compared with the prior art, the device has the advantages of being minimally invasive, reducing the pain of a patient, shortening the operation time, facilitating operation of a doctor, improving the operation efficiency, removing a vertical incision during periosteum tension reduction, reducing postoperative suture wound cracking, preventing the risk of infection caused by bone meal exposure, providing an effective solution for complex oral implant cases, and having a wide application prospect. And the treatment experience and satisfaction degree of the patient are improved.

The application discloses a post-cesarean section anti-slipping wound compression hemostasis device and belongs to the technical field of medical devices. The device comprises an elastic band, a third air bag installed on the inner side of the elastic band, and a compression mechanism located on the outer wall of the elastic band and used for expanding the third air bag to stop bleeding of a patient's wound. The compression mechanism comprises an auxiliary component arranged on the outer wall of the elastic band. The third air bag is flexibly connected to the surface of the wound and has no sharp edges or hard points, so that friction and tearing of the sutured wound and damaged skin can be avoided, the integrity of the wound surface is protected, skin ulcer and nerve damage (such as the "local pressure sores" risk of a traditional hemostasis band) caused by excessively high local pressure can be avoided, the third air bag can be inflated to be attached to the curved surface of the human body, the problem of poor attachment and pressure dead angle caused by rigid compression is solved, and the recovery effect of the incision of the patient after the cesarean section is improved.

The utility model discloses a medical skin stitching instrument which comprises at least one group of stitching pull buckles, each group of suturing pull buckles comprises a first medical adhesive block and a second medical adhesive block which are respectively adhered to the skin on two sides of a sutured wound, and a first tensioning adhesive block which is fixedly connected with the first medical adhesive block through a first tensioning piece; the first medical viscose block is fixedly connected with the first tensioning viscose block through a first tensioning piece, the second medical viscose block is fixedly connected with the second tensioning viscose block through a second tensioning piece, the first medical viscose block, the second medical viscose block, the first tensioning viscose block and the second tensioning viscose block are all provided with release pieces, the structure is simple, machining is convenient, the suturing effect is good, and a wound is smooth.

The utility model discloses a retainer for suturing a skin wound, which belongs to the field of medical instruments for suturing the skin wound, and comprises two adhesive pieces, pre-tightening components are respectively mounted on two sides of the upper ends of the two adhesive pieces, and a plurality of limiting components which are distributed in a staggered manner are mounted on the center sides of the upper ends of the two adhesive pieces. A protective part is attached to the upper end of one adhesive part, the adhesive part comprises a plastic base beam and an adhesive plate, the adhesive plate is fixedly connected to the side end of the plastic base beam, and a first covering film is attached to the lower end of the adhesive plate, so that pre-gathering operation can be conducted on the cracked edge end of a wound before the wound is sutured, tension after the wound is cracked is reduced, and subsequent personnel can conduct suturing more conveniently; meanwhile, trauma of the wound is reduced, the wound position after suturing is kept subsequently, the thread opening phenomenon is avoided, and under the action of the protection piece, the wound after suturing can be waterproof, and the healing rate is increased.

The invention belongs to the field of medical sutures, and particularly provides an antibacterial PDO suture and a preparation process thereof, and the preparation process comprises the following steps: taking PPDO particles, fully drying the PPDO particles, then carrying out melt spinning, then sequentially carrying out traction, corona and dipping treatment, and then washing and drying the PPDO particles to obtain the antibacterial PDO suture. The dipping treatment is carried out in a coating solution; the PDO suture line prepared after being treated by the coating liquid has the advantage of lasting antibacterial property, and slow degradation is beneficial to playing a long-term fixing role on a sutured wound.

The left and right push plates are pushed by pan head bolts to oppositely move towards the two sides of a wound, tissues on the two sides are extruded to protrude towards the middle, and tissue tension is changed into tissue tightening force; a pan head bolt pushes a pressing plate and a breathable plate to move downwards, a wound bulge is wedged and flattened, tissues on the two sides of a wound are in airtight-level fit, tissue hyperplasia can only be forcibly carried out subcutaneously, the tissue butting and anastomosis speed is increased, the body surface is always kept in a flat, smooth and non-hyperplasia state, microorganisms can be effectively prevented from invading the wound, and the wound healing effect is improved. Infection is prevented, so that rapid scar-free healing of sutured wounds is realized. Transverse thrust, vertical pressure and body binding force can be finely adjusted in a stepless mode through the buckles so as to adapt to the tolerance of a patient.
