When in use, the medical staff can adjust the sequence of the first punching piece, the second punching piece and the third punching piece according to the operation requirement. In nasal plastic surgery, a first punch is used for skin punching to obtain acellular dermal matrix (acellular dermal matrix, ADM), and the allogenic or xenogenic dermis is subjected to pancreatin digestion to remove the dermal matrix after the epidermis cell components. The collagen fiber bundle comprises normal skin collagen fiber bundles and an intact basement membrane structure, has strong biological affinity and lower immunogenicity, and can be used as an induction bracket for re-implantation of receptor fibroblasts and vascular endothelial cells. Is applied to wound surface covering or filling of subjects such as burn, plastic, oral cavity and the like. The second perforating piece is used for cutting the comfort platinum material, the comfort platinum material is suitable for orthopedic surgery, the outline improvement of the nose can be carried out, the bone tissue of the part can be fully replaced, the effect of remodelling the nose structure can be achieved, normal vascularization can be carried out in part after implantation surgery is finished, infectivity is not easy to occur, and the comfort platinum material can be stored in the body for a long time and cannot be absorbed. The third puncher is used for obtaining the self-body ear cartilage, filling the nose bridge with the self-body ear cartilage bone, and healing with the tissue of the nose part into a whole, so that the puncher is easy to fix and does not shift; no rejection reaction occurs; the absorption is less, the absorption rate of autologous cartilage is low, and the autologous cartilage can survive without blood supply; the operation is simple, the product is taken from the body, and the acquisition is easy. And because the hardness of skin, comfort platinum material and ear cartilage is different, the degree of sharpness of the perforating needle 102 of first perforating piece, second perforating piece and third perforating piece is also different, and the degree of sharpness of the perforating needle 102 of first perforating piece, second perforating piece and third perforating piece increases in proper order.

After punching, the punching members 1 are sterilized and washed, and then are connected again to be stored.

In the utility model, a plurality of punching parts 1 are combined, and when in use, each section of handle 101 is combined together, so that a longer holding part can be provided, and the handle is convenient for medical staff to hold and use. Except that the perforating needle 102 of the perforating component 1 at one end of the combination body 100 is exposed, the other perforating needles 102 are all accommodated in the accommodating part 1011, so that the size of the combination on the length is reduced, the accommodating and packaging are convenient, and the perforating needle 102 can be protected on the other hand, the cutting edge of the perforating needle 102 is not easy to wear, and the sharpening frequency of the perforating needle 102 is reduced. Each punching part 1 is combined together, and when surgical equipment is prepared, the punching parts 1 with different specifications do not need to be taken from different storage areas for multiple times, so that the surgical equipment is convenient to take and is not easy to lose. In addition, the hollow handle 101 is communicated with the perforating needle 102, so that the cleaning and the disinfection are facilitated, and the cleanliness of the instrument is ensured.

In the practical application process of the utility model, the number of the punching components 1 and the specification of the punching components 1 in the combination 100 can be determined according to the operation requirement, so that different combinations can be conveniently selected according to different operations. In addition, the adjacent punching members 1 in the assembly 100 may be detachably connected, and may be screwed or snap-connected, as shown in fig. 4.

As shown in fig. 1, in a preferred example, the length of the punching needle 102 is smaller than the depth of the accommodating portion 1011, and the diameter of the punching needle 102 is smaller than the diameter of the accommodating portion 1011. On the one hand, the accommodating portion 1011 is ensured to have enough accommodating space for accommodating the punching needle 102, and on the other hand, the punching needle 102 is prevented from contacting with the wall surface of the accommodating portion 1011, thereby preventing the punching needle 102 from being worn out.

As shown in fig. 1, in a preferred embodiment, both ends of the assembly 100 are provided with end caps 2, and the end caps 2 are screwed with the assembly 100. The end cap 2 includes a front cover 201 and a rear cover 202, the front cover 201 is connected to the first connection portion 1012, and the rear cover 202 is connected to the second connection portion 1013. The front cover 201 of the end cover 2 is arranged at the front end of the combination body 100, covers the outer side of the punching needle 102 of the punching component 1 at the forefront end of the combination body 100, is connected with the first connecting part 1012 of the punching component, and protects the punching needle 102; the rear cover 202 is provided at the rear end of the assembly 100, covers the tail of the punch member 1 at the extreme end of the assembly 100, is connected to the second connection part 1013 of the punch, and covers the accommodating part 1011 of the punch. By arranging the end caps 2 at two ends of the combination body 100, two ends of the combination body 100 are closed, and the combination body 100 is further protected, so that the perforating needle 102 is not easy to be polluted.

In practical application, the two ends of the combination body 100 are detachably connected with the end covers 2, the end covers 2 are in threaded connection or clamping connection with the combination body 100, and the connection mode of the end covers 2 and the combination body 100 is the same as the connection mode of each punching part 1 in the combination body 100.

As shown in fig. 2, in a preferred embodiment, the outer surface of the handle 101 is provided with a non-slip texture 1014. The roughness on the surface of the handle 101 is increased by the protective textures, so that the friction force between hands and the handle 101 is increased when a medical staff holds the handle, the handle is firmer to hold, and the medical staff can operate conveniently.

As shown in fig. 2, in a preferred embodiment, the penetrating end of the perforating needle 102 is provided with serrations 1021. The sawtooth 1021 on the perforating needle 102 increases the sharpness of the penetrating end of the perforating needle 102 on the one hand, so that the perforating needle is convenient to penetrate into skin, cartilage or prosthesis, labor is saved, and the perforating needle 102 can be rotated to cut the skin, cartilage or prosthesis, so that the medical staff can conveniently operate.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
