TECHNICAL FIELD
[0001] The utility model relates to a kind of medical instruments field, in particular to a kind of effective anti-organ shift's resistance seat. BACKGROUND
[0002] Anastomat is the device used in medicine to replace traditional hand sewing, its main working principle is to use titanium nail to cut or anastomose tissue, similar to stapler.According to different application range, it can be mainly divided into skin anastomat, digestive tract circular anastomat, rectal anastomat etc.Anastomat has the advantages of convenient use, tightness, suitable tightness, especially its rapid sewing, simple operation, few side effects and surgical complications, and is favored and respected by domestic and foreign clinical surgeons.To successfully complete sewing, resistance seat is generally needed to be installed on anastomat, and the quality of resistance seat will directly affect the sewing effect and the recovery of patient's wound after operation.
[0003] During clamping and cutting, tissue shift affects the quality of sewing (nail forming), so the tissue needs to be fixed to reduce movement.Anastomat reduces tissue shift by the closing force applied by the jaw and the gecko claw structure on the nail cartridge surface, but due to the smoothness of the tissue surface and the sharpness deviation of the cutting knife, the cutting resistance is large, and in actual use, the tissue still exists shift, which will affect the nail forming and ultimately affect the operation effect. SUMMARY
[0004] The main purpose of the utility model is to provide a kind of effective anti-organ shift's resistance seat.
[0005] To achieve the above purpose, the technical scheme adopted by the utility model is as follows:
[0006] An effective anti-organ shift's resistance seat, comprising a nail seat body, arc-shaped guard plates are fixedly arranged on both sides of the tail part of the nail seat body, a knife path groove is fixedly arranged at the center of the nail seat body, a plurality of nail resistance grooves are fixedly arranged on the upper end surface of the nail seat body, recesses are further fixedly arranged on both sides of the upper end surface of the nail seat body along the length direction of the nail seat body, protruding parts are fixedly arranged at the edges of both sides of the upper end surface of the nail seat body, the nail resistance grooves are formed by the intersection of the sharp parts of two water-drop-shaped grooves, forming a nail resistance groove structure with wide ends and narrow middle, and the length direction of the nail resistance groove is the same as the length direction of the nail seat body.
[0007] Further, the protruding parts are a plurality of protruding hemispherical structures.
[0008] Further, the protruding parts are a plurality of small bosses, and the edges and corners of the upper end surface of the small bosses are provided with chamfers.
[0009] Further, the protruding parts are long-strip-shaped rectangular bosses, and the edges and corners of the upper end surface of the rectangular bosses are provided with chamfers.
[0010] Further, the stop nail grooves are arranged along the length direction of the nail seat body, and the number of rows of the stop nail grooves arranged on one side of the tool path groove is not less than two.
[0011] Compared with the prior art, the utility model has the advantages that:
[0012] The convex part can effectively reduce tissue slipping during clamping and cutting tissues in surgery, and realize the anti-skid effect; and the 8-shaped stop nail groove formed by two water-drop-shaped grooves can improve the smoothness of the upper end surface of the stop nail seat body.
