Description

Technical Field

[0001] The utility model belongs to the technical field of puncture devices, and particularly relates to a buckle-type sealing puncture device. Background Art

[0002] A trocar is a surgical instrument that pierces the abdominal wall and provides a passage for other surgical instruments to enter the body cavity. It is a minimally invasive surgical instrument. The trocar usually includes a cannula as an entry passage for other surgical instruments and a puncture needle assembly that runs through the cannula. During surgery, first, in order to penetrate the skin, the skin epidermis is cut with a scalpel, and then the puncture needle assembly is used to penetrate the skin and enter the body cavity together with the cannula body. The puncture needle assembly is then pulled out, and the cannula can be used as a passage for introducing various instruments and tools into the abdominal cavity and providing aeration to raise the abdominal wall above the organs. However, in the existing trocars, no corresponding fixing structure is provided on the cannula. When various instruments and tools are introduced into the abdominal cavity through the cannula, the cannula is prone to loosening due to lack of fixation, affecting the normal progress of the operation, thereby increasing the risk of surgery.

The balloon 221 fits the patient's skin from the inside, and the fixing member 234 fits the patient's skin from the outside. The patient's skin is clamped between the balloon 221 and the fixing member 234. Finally, the pressing part 2334 is stopped, and the connecting member 233 moves under the resetting action of the compression spring 2333 so that the clamping part 2332 is clamped again in the thread groove of the external thread 211 of the first sleeve 21, thereby fixing the puncture device through the fixing member 234, preventing the puncture device from loosening during use, and ensuring the smooth progress of the operation. At the same time, the balloon 221 and the fixing member 234 are both tightly fitted to the skin, so that the balloon 221, the fixing member 234 and the skin at the patient's abdominal puncture port are well sealed, which improves the sealing performance between the puncture device and the patient's skin and can effectively prevent gas leakage in the patient's body.
