背景技术Background technique
烧伤植皮是治疗烧伤患者的常见方法。在医学上，由于个体之间的排异反应，对于深度烧伤的治疗，异体皮、异种皮等各种伤面覆盖物对缺皮伤面仅是短期保护，其最终目的是以自身皮细胞的繁殖生长来完成全部覆盖伤面。因此用尽量少的皮源实现最大限度地对伤面的覆盖，是目前医患双方共同追求的目标。Burn skin grafting is a common method of treating burn patients. In medicine, due to the rejection among individuals, for the treatment of deep burns, all kinds of wound surface coverings such as allogeneic skin and heterogeneous skin are only short-term protection for the lack of skin, and the ultimate goal is to use the body's own skin cells. Propagate the growth to complete the full coverage of the wound. Therefore, achieving maximum coverage of the injured surface with as little skin source as possible is the common goal pursued by both doctors and patients.
现有的植皮方法中采用较广的有植皮片切网法，该方法是在大张植皮片上，切若干个彼此大小相等、相互平行、交错排列的切口，横向拉开就如同一张网，将此网状皮片植在伤面后，能保持伤面的一定弹性，有利于肢体功能的回复。目前，植皮片的切网常采用的轧皮机，其结构为：两个直径相同的圆钢辊，两圆钢辊相互平行安装于一个支架上，上面的圆钢辊表面镶嵌有大小相等、相互平行、间距相等、相互交错排列的刀片，而且所有刀片外圆必须同圆。操作时，将切好的大张植皮片平铺于塑料板上，通过手摇柄转动上面有刀片的圆钢辊，并将铺有皮片的塑料板置于两圆钢辊之间辊轧，这样植皮片就被轧出与刀片排列相同的刀口，转动90°继续辊轧，轧切成小皮片；或用扩展刀片轧切植皮片，然后横拉皮片成网。但是由于取得的植皮片的厚度不均，而用于辊轧并装有刀片的两圆钢辊的间距一定，不能调整，因此在辊轧皮片时，会导致切不透的情况，即皮肤切口未被完全切开，植皮之前还需医生用手术刀作补充性切割。In the existing skin grafting method, a wider skin grafting method is adopted. This method is to cut a number of equal-sized, parallel and staggered incisions on a large skin grafting sheet, and stretch them horizontally like a net. After the mesh skin is implanted on the injured surface, it can maintain a certain degree of elasticity of the injured surface, which is beneficial to the recovery of limb functions. At present, the skin rolling machine often used for cutting the skin grafting sheet has a structure of two round steel rollers with the same diameter, and the two round steel rollers are installed parallel to each other on a support. Blades that are parallel to each other, equally spaced, and staggered, and the outer circles of all blades must be the same circle. During operation, spread the cut large sheet of skin graft on the plastic plate, turn the round steel roller with the blade on it through the hand crank, and place the plastic sheet covered with the skin sheet between the two round steel rollers for rolling. In this way, the skin graft is rolled out to the same knife edge as the blade arrangement, rotated 90° to continue rolling, and cut into small skins; However, due to the uneven thickness of the skin grafts obtained, the distance between the two round steel rollers used for rolling and equipped with blades is fixed and cannot be adjusted. Therefore, when the skin grafts are rolled, it will cause the situation that the skin cannot be cut through, that is, the skin The incision is not completely cut, and the doctor needs to make supplementary cuts with a scalpel before skin grafting.

Specifically, as shown in FIG. 3 , the gear 8 includes two meshing upper roller gears and lower roller gears. One end of the upper roller 17 passes through the upper roller groove of the first side plate 1 and extends to the outside of the first side plate 1 to be fixedly connected with the upper roller gear. Similarly, one end of the lower roller 19 passes through the lower roller hole of the first side plate 1 and extends out of the first side plate 1 to be fixedly connected with the lower roller gear. That is, after the lower roller 19 is rotated, the gear of the lower roller also rotates, which drives the gear of the upper roller meshed with the gear of the lower roller to rotate in the reverse direction, and drives the upper roller 17 to rotate in the reverse direction, that is, the upper roller 17 and the lower roller 19 are reversed at the same time. turn.

For example, a concave keyway is provided on the inner surface of the upper roller gear, and a protruding keyway is provided on the surface of the upper roller 17. The upper roller gear 17 is sleeved on the upper roller 17, and the keyway on the upper roller 17 is aligned with the upper roller gear. The keyway on the top is matched, thereby the upper roller gear is fixedly connected with the upper roller 17. Similarly, the lower roller 19 and the lower roller gear 19 can also be fixedly connected through keyway matching. Preferably, the shaft end screw 22 can also be assembled at one end of the upper roller 17 and/or the lower roller 19 to prevent the upper roller gear from falling off from the upper roller 17 and the lower roller gear from falling off from the lower roller 19 in the working process.
本发明中，为降低上辊17、下辊19转动过程中与第一侧板1、第二侧板21之间的摩擦力，如图1、2、3所示，上辊17的两端分别通过第一轴承16转动安装于上辊槽内；如图3所示，下辊19的两端分别通过第二轴承24转动安装于下辊孔内。In the present invention, in order to reduce the friction force between the first side plate 1 and the second side plate 21 during the rotation process of the upper roller 17 and the lower roller 19, as shown in Figures 1, 2 and 3, the two ends of the upper roller 17 The two ends of the lower roller 19 are rotatably installed in the lower roller hole through the second bearing 24 respectively, as shown in FIG. 3 .
