A method for using in the accurate apparatus that punctures of position of surgical approach in the laparoscopic surgery, wherein, at first, according to patient's CT result, measure the thickness of the patient's chest wall or abdominal wall, confirm the depth that the inner tube will enter, turn the nut on the upper place of inner tube through the external screw thread from the lower place of inner tube first, then cooperate with internal thread of the outer tube through the external screw thread of the inner tube, embolia the outer tube from the lower place of inner tube, rotate to the upper place of inner tube along the external screw thread, until the stop piece of the outer tube is parallel to scale that will enter on the inner tube, then turn the nut of the upper place and lock with the outer tube rotatably, at last, perpendicular to skin incision direction of inner tube and skin, insert the inner tube into the incision hard, when the outer tube contacts with skin, and the inner tube has broken through and feels, indicate that the puncture is successful, the surgical approach has already been opened at this moment, the operator can carry on the next step of surgical operation.
The invention has the following beneficial effects: 1. according to the invention, through the design of the scales on the inner tube and the position of the outer tube, the thickness of the chest wall or the abdominal wall of a patient can be measured according to a CT image of the chest and the abdomen, the puncture depth is adjusted, and the possibility that the puncture device damages the organs of the patient is reduced while efficient and accurate puncture is performed.
2. According to the invention, through the design of the threads on the inner tube, under the conditions that pneumoperitoneum is not completely established and lung is not completely collapsed, the force of a surgeon during puncture can be accurately controlled during puncture, and the surgeon can be effectively fixed with the puncture part, so that the possibility of skewness of the puncture route is reduced. The collateral damage to the patient is reduced, and the operation risk and the occurrence possibility of operation complications are reduced.
3. In the invention, the inner tube and the outer tube are both made of disposable materials, thus solving the problems that the traditional puncture outfit is difficult to clean and disinfect incompletely after repeated use and avoiding nosocomial infection.
