Laparoscope puncture outfit device

Abstract

The invention relates to a laparoscope puncture outfit device. The device comprises a puncture sleeve and a puncture needle, and a channel for the puncture needle to penetrate through is arranged on the vertical center of the puncture sleeve and denoted as a puncture channel; when the device is in use, the puncture needle penetrates through the puncture channel, is inserted into the puncture sleeve, and extends out of the tail end of the puncture sleeve; an air filling valve is installed on the side wall of a puncture sleeve base and integrated with the puncture sleeve; the puncture sleeve comprises a puncture sleeve body and two levels of sealing devices, the puncture sleeve body comprises the puncture sleeve base and a sleeve body, the two levels of sealing devices are installed above the puncture sleeve base, and the sleeve body is installed below the puncture sleeve base; the air filling valve is installed on the side wall of the puncture sleeve base and integrated with the puncture sleeve. The laparoscope puncture outfit is light in overall structure and can effectively ensure a dynamic sealing effect in an operation process, it can be ensured that the an enterocoelia operation is conducted normally and fluency in an operation instrument movement process is high, the usage is convenient, and the device is safe and reliable.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a laparoscopic puncture device. Background technique [0002] In minimally invasive human medical surgery, once a disease is found in the human body, surgery or resection is required. During the operation, the puncture device is first used. The puncture device is a kind of operation that pierces the abdominal wall and enters the body cavity for other surgical instruments. An instrument belongs to a minimally invasive surgical instrument. A trocar usually includes a sleeve assembly serving as an access channel for other surgical instruments and a puncture rod penetrating through the sleeve assembly. First, in order to penetrate the skin, cut the epidermis of the skin with a scalpel, then use the puncture rod to penetrate the skin and enter the body cavity together with the sleeve assembly, and then pull out the puncture rod, the sleeve assembly can be used to introduce various ...

AI Technical Summary

Problems solved by technology

[0003] In the process of establishing pneumoperitoneum, air leakage between the outer sheath and the incision site of human tissue often occurs, resulting in the failure of pneumoperitoneum establishment; During the whole operation, the doctor will constantly adjust the insertion angle of the puncture device according to the needs of the operation and take out or insert the surgical instruments reciprocally, which will also cause the puncture device to slip off and leak air; The puncture needle is also equipped with an exposed blade. Since the blade with the puncture head is always exposed, it is easy to accidentally injure the internal organs of the human body after entering the incision of human tissue. Therefore, special attention must be paid to the medical staff. Operational strength increases the difficulty of operation for medical staff

As can be seen from the above, the puncture device in the prior art is inconvenient to use and has low reliability and safety
