Visual puncture outfit capable of keeping abdominal pressure

Abstract

The invention discloses a visual puncture outfit capable of keeping abdominal pressure. The visual puncture outfit comprises a sealing shell, a puncture outfit cap and a lower sealing cover, wherein the sealing cover is installed at the top of the sealing shell in a threaded mode; a first groove is formed in the bottom of the sealing cover; a rotary knob is rotationally connected to the right end of the sealing cover; the lower end of the rotary knob is arranged in the first groove; a second groove is formed in the top of the sealing cover; a rotating disc is rotationally connected inside the second groove; and a gear ring is fixed to the top of the rotating disc. The visible puncture outfit capable of keeping the abdominal pressure is provided with a positive electrode, a negative electrode, a driving motor and a first screw rod; and when a puncture needle punctures the inner wall of the abdominal cavity of a patient, the positive electrode and the negative electrode are both separated from the skin of the patient, at the moment, the positive electrode and the negative electrode are electrically disconnected, a controller detects disconnection and starts a driving motor, the driving motor drives the first screw rod to rotate, and the first screw rod pulls the puncture needle to contract until the puncture needle is completely contracted in a cannula, so that the puncture needle is prevented from puncturing the viscera of the patient, and the use is safer.

Description

technical field [0001] The invention relates to the technical field of puncture devices, in particular to a visible puncture device capable of maintaining abdominal pressure. Background technique [0002] Trocar is a medical device for minimally invasive surgery. Its structural sleeve runs through the patient's abdominal wall, and the sleeve can provide a passage for surgical instruments to enter the patient's abdominal cavity. [0003] Existing puncture devices usually only have one sealing film, and different surgical instruments have different diameters and sizes. Sharing the same type of sealing film is likely to cause the problem of poor sealing, which in turn increases the probability of air leakage, which is not practical enough to use. Moreover, the structure of existing trocars is too complex, and there are too many non-detachable parts, which increases the difficulty of disinfection and is easy to cause residues, which has certain hidden dangers in use. Existing tr...

Problems solved by technology

[0004] The object of the present invention is to provide a visual puncture device that can maintain abdominal pressure, to solve the problem that the existing puncture device proposed in the above background technology is usually only provided with a sealing film, and different surgical instruments have different diameters and sizes, and share the same The sealing film of the model is easy to cause the problem of poor sealing, which then increases the probability of air leakage, which is not practical enough to use, and the structure of the existing trocar is too complicated, and there are too many non-detachable parts, which increases the difficulty of disinfection. It is also easy to cause residue, and there are certain hidden dangers in use. The existing puncture device is usually not equipped with an anti-accidental organ structure. , regardless of safety issues when using
