Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

With reference to the accompanying drawings 1-5, a puncture combination device comprises a puncture needle 1, and further comprises a skin cutting part 2, an expansion part 3, a support part 4 and a cutting part 5, wherein:

the puncture needle 1 is used for puncturing and entering a body cavity after passing through soft tissue, and a detachable handle 101 is arranged at one end of the puncture needle;

the skin cutting piece 2 is used for cutting skin after being sleeved outside the puncture needle 1, and the skin cutting piece 2 is of a hollow structure;

the expansion piece 3 is sleeved outside the puncture needle 1 to expand the soft tissue, and at the moment, the skin cutting piece 2 is detached from the puncture needle 1;

the support piece 4 is sleeved outside the puncture needle 1 to support soft tissues, and at the moment, the expansion piece 3 is firstly pulled out of the puncture needle 1;

the incision piece 5 is used for sleeving the support piece 4 and then incising the incision on the inner wall of the body cavity and expanding the incision.

When the puncture treatment is carried out by using the device, the puncture treatment is carried out according to the following steps: firstly, the puncture needle 1 is arranged in soft tissue of a patient and extends into a body cavity through the handle 101, then the handle 101 is removed, and the skin cutting piece 2 is sleeved outside the puncture needle 1 for skin cutting; then, the skin cutting part 2 is taken down, and the expansion part 3 is sleeved outside the puncture needle 1, so that the soft tissue is expanded; then, the stent 3 is removed, the supporting member 4 is fitted to the outside of the puncture needle 1, and the incision of the inner wall of the body cavity is made along the supporting member 4 by the incision member 5 and enlarged, thereby completing the whole puncture process.

The dermatome 2 comprises a hollow dermatome 21, the dermatome 21 comprises a hollow cutter head 211, a hollow rod 212 and a cutter handle 213 which are connected in sequence, wherein the cutter head 211 is of a structure with a V-shaped tip at the end part, the hollow rod 212 is of a belt shape, a cavity 214 penetrates through the hollow rod 212 and the cutter head 211 from top to bottom, and the cavity 214 can accommodate the puncture needle 1.
