Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary devices, specifically relating to an auxiliary stretching device for artificial skin suturing. Background Technology

[0002] In recent years, burn patients have continued to constitute a significant proportion of all types of trauma patients both domestically and internationally. Burn treatment involves multiple aspects, including fluid resuscitation, shock management, electrolyte balance, and stabilization of organ function. Furthermore, wound management and repair are crucial to the entire burn treatment process. Generally, superficial burns or small-area burns can heal spontaneously after dressing changes and topical medications. However, large-area deep burns require skin grafting to cover the wound and minimize exposed areas. This remains a challenge for patients with large-area burns or those with limited natural skin margins. With advancements in biomedical engineering, the application and development of various artificial skins, such as allogeneic or xenogeneic skin (e.g., pigskin), have provided new options for burn wound repair. Artificial skin can temporarily cover the wound, preventing infection and deepening. Before complete wound repair, allogeneic or xenogeneic skin can provide a similar covering effect to autologous skin. However, because the skin grafts are prefabricated, the size or shape of the artificial skin (including allogeneic or xenogeneic skin) cannot perfectly match the actual wound condition. Therefore, it is necessary to splice the artificial skin to match the wound. Pre-splicing the artificial skin facilitates overall coverage of the surgical area, shortening the operation time and reducing surgical and anesthetic risks. Currently, skin graft splicing still requires manual operation by the surgeon. In cases of large-area burns, the workload is heavy, the artificial skin is prone to shifting during suturing, and splicing is time-consuming, laborious, and inefficient, severely impacting the surgical progress. Currently, however, there is no specialized auxiliary equipment available for artificial skin splicing and suturing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary stretching device for suturing artificial skin, which can fix and stretch the artificial skin to avoid the movement of the skin piece during the suturing process.

[0004] The technical solution adopted in this utility model is:

[0005] An auxiliary stretching device for artificial skin suturing includes a base, a support plate embedded on the surface of the base, and extension devices disposed on the top surface of the base and located on the left and right sides of the support plate. The top surface of the support plate is flush with the top surface of the base, and there are two of them, which are movably disposed in the embedding groove on the top surface of the base.

[0006] Furthermore, the extension device includes a gantry frame fixedly mounted on the base, an elastic connector mounted on the gantry frame, and a pressure plate fixed to the bottom of the elastic connector.

[0007] Furthermore, fixing teeth are provided on the bottom surface of the pressure plate.

[0008] Furthermore, the elastic connector includes a sleeve fixed on the gantry frame, a connecting rod sleeved inside the sleeve, and a spring disposed on the connecting rod. The upper end of the connecting rod is located inside the sleeve, and the lower end is fixedly connected to the pressure plate. The spring is located between the sleeve and the pressure plate.

[0009] Furthermore, an outwardly protruding slide rail is provided on the side wall of the mounting groove, and a slide groove that matches the slide rail is provided on the side wall corresponding to the tray.

[0010] Furthermore, a spring positioning bead is provided on the bottom surface of the embedding groove near the inner end, and a positioning groove for cooperating with the spring positioning bead is provided on the bottom surface of the support plate.

[0011] Furthermore, several rollers are provided on the bottom surface of the embedding groove, located outside the spring positioning bead.

[0012] Furthermore, a clearance groove is provided on the bottom surface of the embedding groove, directly below the position where the two trays are close together.

[0013] The positive effects of this utility model are:

[0014] This invention features an extension device at both ends of the top surface of the base. The two extension devices work together to firmly and tautly press the artificial skin onto the base. The top surface of the support plate is flush with the top surface of the base, further facilitating the flattening of the artificial skin. Simultaneously, there are two support plates, movably positioned within the mounting groove. When both support plates are pushed outwards simultaneously, the gap between them can be used as space for sutures. When the two support plates contact each other, they form a complete plane, which helps to flatten and align the two artificial skins, improving the efficiency of subsequent sewing.

[0019] As attached Figure 1-4As shown, this utility model discloses an auxiliary stretching device for suturing artificial skin, including a base 1, stretching devices disposed at the left and right ends of the top surface of the base 1, and a support plate 4 disposed between the two stretching devices. A mounting groove 12 is provided on the top surface of the base 1, and the support plate 4 is disposed inside the mounting groove 12. There are two support plates 4, which are movably connected to the mounting groove 12 and can move within the mounting groove 12, thus creating a certain gap between the two support plates 4 to provide space for the movement of the suture needle during suturing. In the initial state, the inner surfaces of the two support plates 4 are in contact and located at the center line of the top surface of the base 1. The artificial skin can be directly laid on the plane formed by the support plate 4 and the top surface of the base 1.

[0020] The stretching device includes a gantry frame 3 fixedly mounted on the base 1, elastic connectors on the top left and right sides of the gantry frame 3, and a pressure plate 7 fixedly mounted on the bottom of the elastic connectors. The bottom surface of the pressure plate 7 is provided with fixing teeth 8. The elastic connectors provide downward force to the pressure plate 7, and the two ends of the artificial skin are pressed onto the base 1 by the fixing teeth 8, thereby achieving the stretching and fixing of the artificial skin.

[0021] Preferably, the elastic connector includes a sleeve 15 fixed to the portal frame 3, a connecting rod 5 fitted inside the sleeve 15, and a spring 6 disposed on the connecting rod 5. The top end of the sleeve 15 is fixed to the portal frame 3, and the pressure plate 7 is fixedly installed at the lower end of the connecting rod 5. The spring 6 is located between the sleeve 15 and the pressure plate 7, and the spring 6 provides downward pressure to the pressure plate 7. To prevent the fixing teeth 8 from damaging the artificial skin, a silicone pad can be provided on the base 1, directly below the pressure plate 7.

[0022] An outwardly protruding slide rail 13 is provided on the inner side wall of the mounting groove 12, and a sliding groove adapted to the slide rail 13 is provided on the corresponding side wall of the support plate 4. By setting an appropriate sliding groove length, the two support plates 4 can be made to fit together perfectly when the support plate 4 is moved inward to its limit position.

[0023] As attached Figure 3 As shown in another embodiment of this utility model, two spring positioning beads 9 are provided on the bottom surface of the embedding groove 12, near the inner end. Their main bodies are embedded in the embedding groove 12, with the positioning pins protruding outwards. A positioning groove 10 is provided on the bottom surface of the support plate 4 to cooperate with the spring positioning beads 9. When the support plate 4 moves inwards to its limit position, the spring positioning beads 9 and the positioning groove 10 cooperate perfectly, acting as a limit and preventing the support plate 4 from moving outwards. In the working state, when the support plate 4 moves outwards, the spring positioning beads 9 can also cooperate with the inner surface of the support plate 4 to prevent the support plate 4 from moving inwards and affecting the sewing process.

[0024] Preferably, a plurality of rollers 14 are provided on the bottom surface of the mounting groove 12, and the top height of the rollers 14 is slightly lower than the top surface height of the spring positioning bead 9, so as to improve the smoothness of the movement of the tray 4.

[0025] Considering that the thickness of the tray 4 is relatively small, the reserved space between the two trays 4 may not be high enough. Therefore, a clearance groove 11 is opened in the middle of the embedding groove 12 to ensure that space is reserved for the needle eye to pass through during sewing. The length direction of the clearance groove 11 is consistent with the length direction of the base 1.

[0026] The method of using this utility model is as follows:

[0027] (1) Place the two artificial skin pieces on the base 1 and the support plate 4. First, align the two artificial skin pieces together and flatten them fully. Press them under the stretching device at one end to fully stretch the two artificial skin pieces. Then, fix the fixing teeth of the stretching device at the tail end so that the two artificial skin pieces are fully stretched. If the artificial skin is too long, lay the excess part flat at the tail end of one stretching device and fasten the fixing teeth of the stretching device. After the target area is sewn, move the remaining unsewn part to the position between the two stretching devices.

[0028] (2) Move the tray to both sides to expose the suture cavity.

[0029] (3) The artificial skin is sutured and fixed according to the conventional surgical suturing method.

[0030] (4) Put away the equipment in a timely manner. Operation complete.

[0031] This invention features an extension device located at both ends of a fixed support, with the artificial skin secured below by fixing teeth. This device extends and moderately tightens the artificial skin to maintain a certain tension. It can be used for the splicing and suturing of artificial skin during surgery, assisting in the splicing and suturing process, effectively saving manpower, improving work efficiency, and shortening surgical time. This invention is rationally designed, simple to operate, and highly practical.
