Anti-drop's peritoneoscope puncture ware

Technical Field

The utility model relates to the field of medical equipment, in particular to anti-drop's peritoneoscope puncture ware.

Background

Laparoscopic surgery is currently the most clinically used surgical procedure. The puncture outfit is a necessary instrument for establishing an operation channel in laparoscopic surgery. The skin epidermis is first incised with a scalpel, and then the puncture device is penetrated through the skin into the body cavity. And then the puncture vertebra is drawn out, and the surgical instrument can be placed into the puncture sheath through the channel of the puncture sheath to perform surgical operation. In the laparoscopic surgery process, a surgery may need dozens of or even more surgical instruments to pass in and out of the puncture sheath canal channel, so the puncture sheath canal often appears and deviates from the external or excessively goes deep into the internal condition, can not effectively fix, if the puncture sheath canal deviates from the external, the operator needs to puncture once more and place the puncture sheath canal, not only increases the surgery time, influences the surgery quality, still can aggravate the incision wound of the patient. If the puncture sheath is too deep in the body, it may puncture the patient's organ. In addition, for patients with thin body and poor skin elasticity, a gap is easy to be formed between the puncture sheath tube and the body wall of the patient, so that gas in the body cavity is easy to leak, subcutaneous emphysema complications are easy to cause, and operation risks and pain of the patient are increased.

In view of the above, there is a need to improve the existing laparoscopic puncture outfit technology to achieve the purposes of good fixing effect and effectively preventing falling off.

An anti-drop laparoscope puncture outfit comprises a puncture sheath tube 1, a puncture cannula seat 2 connected with the puncture sheath tube 1 and a puncture cone 3 sleeved in the puncture sheath tube 1, wherein the puncture cone 3 integrally penetrates through the puncture cannula seat 2 and the puncture sheath tube 1, the end part is cone-shaped and can easily puncture skin, the side wall of the puncture cannula seat 2 is provided with a first inflation valve 4 and a first valve switch 5 connected with the first inflation valve 4, gas is provided for the puncture cannula seat 2 mainly through the first inflation valve 4, the side wall of the puncture sheath tube 1 is also provided with grooves 6, the grooves 6 are communicated with an inner cavity of the puncture sheath tube 1, the number of the grooves 6 is 2-6, in the embodiment, the number of the grooves is preferably 4, the specific distribution can refer to figure 1, the grooves are uniformly distributed on the side wall of the puncture sheath tube 1, air bags 7 are attached in the grooves 6, one end, close to the puncture sheath tube 1, of the side wall of the puncture cannula seat 2 is provided with a second inflation valve 8, the second inflation valve 8 is connected with the airbag 7, the second inflation valve 8 is further connected with a second valve switch 9, and the connection mode of the second inflation valve 8 and the second valve switch 9 is any connection mode in the prior art, and the connection mode is not limited in many places.

When the laparoscopic puncture outfit is used specifically, the surgical site of a patient is cut by a scalpel, the puncture cone 3 is sleeved into the puncture sheath tube 1 and penetrates into the body of the patient together, the puncture cone 3 is taken out after successful puncture, and an operator determines whether to fill the body cavity with carbon dioxide gas or not and can fill the body cavity with the carbon dioxide gas through the first inflation valve 4. After the puncture sheath tube 1 is positioned, the second inflation valve 8 is used for inflating air to enable the air bag 7 to be expanded until the puncture sheath tube 1 and the incision expanded by the patient are firmly fixed, and then the second valve switch 9 is closed. The laparoscope puncture outfit can be prevented from shifting and falling off in the whole operation process, so that the puncture outfit is tightly attached to the incision of a patient, and the subcutaneous emphysema caused by the fact that external gas enters the subcutaneous part of the patient through the incision of the patient can be prevented. And the position of the puncture outfit is repeatedly adjusted in the operation process, the tissue damage is reduced, the operation risk is reduced, and the operation time is shortened.

Meanwhile, the first inflation valve 4 is not only used for selectively ventilating, but also can be changed into a liquid valve according to actual conditions, so that the transfusion to the body of a patient is facilitated.
