A paediatrics puncture ware theory of operation:
a pediatric puncture instrument that requires insertion of a puncture cone assembly into a cannula assembly prior to use; when puncturing, the puncture conical cover is propped against by the palm, and the forefinger presses on the puncture guide surface of the puncture cannula. When the puncture starts, the conical surface of the puncture conical tip and the auxiliary separation blade firstly separate the incision, and then the puncture guide surface of the puncture sleeve expands the incision, so that the pediatric puncture outfit can puncture into tissues smoothly; finally, the tissue is attached to the anti-slip thread of the puncture cannula, and the pediatric puncture outfit is fixed in the incision. After the penetration is complete, the puncture cone assembly is withdrawn from the cannula assembly.
When pneumoperitoneum is established, a standard connector of a pneumoperitoneum machine is connected with an air injection valve of a pediatric puncture outfit, then an air injection switch is rotated, and the pediatric puncture outfit is communicated with the pneumoperitoneum machine and an abdominal cavity to inject air into the abdominal cavity of a patient; the gas injection speed can be adjusted by adjusting the angle of the gas injection switch. The paediatrics puncture outfit of pneumoperitoneum machine need not be connected, need rotate the gas injection switch to perpendicular with the gas injection valve, close the gas injection function to avoid causing gas leakage.
When the pneumoperitoneum machine starts to inject air, the air blocking piece on the air blocking cap of the pediatric puncture outfit is tightly closed under the action of pneumoperitoneum pressure, so that the problem that the operation is influenced due to unstable pneumoperitoneum pressure caused by air leakage is solved.
When surgical instruments are inserted into the pediatric puncture outfit, the air blocking hole in the middle of the sealing sheet of the pediatric puncture outfit wraps the instruments, so that the problem that the surgery is influenced due to unstable pneumoperitoneum pressure caused by air leakage caused by the entering of the instruments is avoided.
After the operation, dial out surgical instruments from paediatrics puncture ware, open the gas injection switch, with the gas in the patient's abdominal cavity outside the gas vent discharge body of gas injection valve, treat gas discharge back, can dial out paediatrics puncture ware from patient's belly.
The utility model provides a paediatrics puncture ware reasonable in design, this paediatrics puncture ware small and exquisite exquisiteness, the structure is inseparable, and the part is few, and is with low costs, possesses this some functions of puncture ware simultaneously. The puncture outfit is uniquely designed aiming at the pediatric clinical operation condition. The pediatric puncture outfit is provided with the extremely short puncture guide surface, the design considers that the abdominal cavity of a child is small, the abdominal wall is thin, and the extremely short puncture guide surface can ensure that the length of the puncture outfit entering the abdominal cavity is reduced when the pediatric puncture outfit is fixed on the abdominal wall, so that the operation space of an operation is improved; therefore, the length of the puncture outfit sleeve is shortened, and the phenomenon that the exposed part is too long after the puncture outfit is fixed, so that the instrument is not easy to insert into the puncture outfit is avoided; meanwhile, after the length is shortened, the weight of the puncture outfit is greatly reduced, and the condition that severe impression occurs on the abdominal wall due to long-time operation is avoided; in addition, after the weight of the puncture outfit is reduced, the pressure of the puncture outfit on the abdominal wall incision is also reduced, and the occurrence probability of incisional hernia is reduced. Considering that the child abdominal wall is thin, when the puncture outfit is used by a doctor, the puncture progress needs to be known in real time according to puncture hand feeling, and the pediatric puncture outfit is subjected to ergonomic research by combining a holding gesture of the doctor during puncture. When the puncture outfit is used for puncture, a doctor props against the puncture conical cover by using the hand center part, the tip of the forefinger finger is pressed on the puncture guide surface, and the other fingers hold the near end of the puncture sleeve; this gesture makes things convenient for the doctor to exert oneself, and the forefinger fingertip presses on the puncture guiding surface simultaneously, and the doctor can get into length through the position control puncture ware puncture of fingertip, has avoided the puncture ware to stab the accident of organ.

When the puncture starts, the conical surface of the conical tip of the puncture cone 1-1 and the auxiliary separation blade 1-1-1 firstly separate the incision, and then the puncture guide surface 2-2-2 of the puncture sleeve 2-2 enlarges the incision, so that the pediatric puncture outfit can puncture into the tissue smoothly; finally, the tissue is attached to the anti-slip thread 2-2-3 of the puncture cannula 2-2, and the pediatric puncture instrument is fixed in the incision. After the penetration is complete, thepuncture cone assembly 1 is withdrawn from thecannula assembly 2.
When pneumoperitoneum is established, a standard connector of a pneumoperitoneum machine is firstly connected with an air injection valve 2-5 of a pediatric puncture outfit, then an air injection switch 2-6 is rotated, the pediatric puncture outfit is communicated with the pneumoperitoneum machine and an abdominal cavity, and air is injected into the abdominal cavity of a patient; the gas injection speed can be adjusted by adjusting the angle of the gas injection switches 2-6. The pediatric puncture outfit which is not connected with the pneumoperitoneum machine needs to rotate the gas injection switch 2-6 to be vertical to the gas injection valve 2-5 to close the gas injection function so as to avoid gas leakage.
When the pneumoperitoneum machine starts to inject air, the air blocking piece 2-4-4 on the air blocking cap 2-4 of the pediatric puncture outfit is tightly closed under the action of pneumoperitoneum pressure, so that the problem that the operation is influenced due to unstable pneumoperitoneum pressure caused by air leakage is solved.
When a surgical instrument is inserted into the pediatric puncture outfit, the air blocking holes 2-3-4 in the middle of the sealing sheets 2-3 of the pediatric puncture outfit wrap the instrument when the instrument enters, so that the problem that the operation is influenced due to unstable pneumoperitoneum pressure caused by air leakage caused by the entering of the instrument is solved.
After the operation is finished, the surgical instrument is pulled out of the pediatric puncture outfit, the gas injection switch 2-6 is opened, the gas in the abdominal cavity of the patient is discharged out of the body from the gas outlet of the gas injection valve 2-5, and the pediatric puncture outfit can be pulled out of the abdominal cavity of the patient after the gas is discharged.
