When the laparoscopic trocar is used, it is equipped with a puncture cone. As a supporting surgical instrument for laparoscopy, the laparoscopic trocar should first establish pneumoperitoneum, then cut a small incision at the appropriate position of the abdomen, fix the laparoscopic trocar on the pneumoperitoneum raised abdomen by hand at a suitable angle, and insert the puncture sleeve of the laparoscopic trocar together with the puncture cone into the small incision, Press and hold the cap of the puncture cone handle of the puncture cone with your hand to wrap the upper cover and press it down. With the puncture cone penetrating the lower layer of soft tissue with a front-end puncture bayonet, enter the soft tissue together with the oblique section with a taper at the lower part of the puncture sleeve.
When the puncture knife cone passes through the soft tissue of the patient's abdomen to the abdominal cavity, the puncture sleeve is inserted into the abdominal cavity with the puncture cone to the middle of the puncture sleeve. Pull the puncture cone out of the puncture sleeve, open the valve switch on the upper part of the gas injection valve, and the gas is injected into the abdominal cavity of the patient from the puncture sleeve through the air inlet, valve core and valve body of the gas injection valve, making the abdominal cavity of the patient bulge, and close the valve switch 7. The abdominal surgery instruments can enter the puncture sleeve from the locking cap, sealing ring, sleeve elastic sealing cap and gas blocking sealing cap of the laparoscopic trocar, and insert into the abdominal cavity through the puncture sleeve, Due to the multiple seals such as sealing ring, sleeve elastic sealing cap and gas blocking sealing cap, the abdominal cavity sealing surgical instrument has good performance, and the gas injected into the abdominal cavity will not leak. The puncture sleeve fixing structure of clamping the puncture device from the inside and outside of the human body, such as positioning ring and airbag, is adopted. When the puncture device penetrates the human body, it is firmly fixed without shaking, and it is not easy to fall off during the operation, The clamping position can be easily adjusted by a locating ring made of elastic soft material. After the operation, pull the surgical instrument out of the laparoscopic trocar, open the valve switch, and discharge the injected gas in the patient's abdominal cavity from the exhaust port of the gas injection valve. After the injected gas is discharged, press the valve core of the one-way valve to discharge the gas filled in the airbag, and then take out the puncture sleeve from the patient's cavity wall, so as to pull the laparoscopic trocar out of the patient's abdomen.
laparoscopic trocar improves the effect
The laparoscopic trocar is reasonably designed, compact in structure, safe and effective in use. It can greatly reduce the wound area, greatly shorten the operation time, facilitate the operation, reduce the bleeding and postoperative infection of patients, and improve the quality of surgery. The postoperative pain is light and the healing is fast. Because the puncture cone is equipped with a puncture bayonet, a puncture knife handle, a puncture cone head, a puncture cone lower sleeve, a puncture cone upper sleeve, a puncture cone handle, a firing safety button, and a puncture cone handle cap, it can easily penetrate the abdominal tissue without scratching other tissues in the abdominal cavity. Due to the multiple seals such as a sealing ring, a sleeve elastic sealing cap, and a gas blocking sealing cap, the sealing abdominal surgery instrument has good performance, and the gas injected into the abdominal cavity will not leak. During the operation, the gas injected into the abdominal cavity through the gas injection valve of the laparoscopic trocar will not leak out during the operation, so as to ensure the normal operation of abdominal surgery and safe and reliable use. Due to the use of a positioning ring and an air bag, which clamp the puncture sleeve of the puncture device from the inside and outside of the human body respectively, when the puncture sleeve of the puncture device penetrates into the human body, it is firmly fixed and will not shake. It is not easy to fall off during the operation, and the clamping position can be easily adjusted through the positioning ring made of elastic soft material.
