Description
Technical Field
The invention relates to an operation auxiliary device, which is applied to the establishment of an abdominal wall internal and external channel in laparoscopic surgery.
Background
The laparoscopic surgery is that a surgical channel is established by placing a sheath tube of an abdominal wall puncture outfit in an abdominal wall, high-pressure gas is injected into the abdominal cavity to expand the abdominal cavity, a space is generated, the abdominal cavity is placed into a columnar laparoscopic to observe the operation process in the abdominal cavity through a hollow tubular structure of the abdominal wall puncture outfit, and surgical instruments with long handles enter the abdominal cavity for operation through the hollow tubular structure of the abdominal wall puncture outfit. The puncture hole of the abdominal wall is tiny, which is called as a keyhole operation, so compared with the traditional open surgery, the abdominal wall operation of the patient has small injury and quick recovery. Obviously, the abdominal wall puncture outfit is an indispensable auxiliary device for laparoscopic surgery.
The abdominal wall puncture outfit mainly comprises a base and a sheath tube, wherein the base comprises a three-way tube air injection valve, an air blocking valve, a rear cover sealing seat and other complex structures and is the main structure of the abdominal wall puncture outfit, and the base is always kept outside the body during operation and does not enter the abdominal wall and the abdominal cavity; the sheath tube of the abdominal wall puncture outfit is a tubular structure with simple structure, enters the abdominal wall and the abdominal cavity in the operation, the abdominal wall puncture outfit can be divided into different types of standards of 3 mm, 5 mm, 10 mm, 12 mm, 15 mm and the like according to the thickness of the sheath, the thicker the sheath is, the larger the wound of the abdominal wall is, for the fat patients with fat abdominal walls, the types of the abdominal wall puncture outfits with lengthened sheath tubes are also needed, so the types of the abdominal wall puncture outfits are various, clinically, the abdominal wall puncture outfits with different types and standards are selected according to the fat and thin of the patients, the types of diseases and the random strain in the operation process, because the base and the sheath tube of the prior abdominal wall puncture outfit are of a one-to-one integrated structure, in order to meet the clinical requirements for different types of sheath tubes, the abdominal wall puncture outfit with a plurality of types is often required to be configured, and each type of abdominal wall puncture outfit is a base corresponding to one sheath tube. However, even so, due to the unpredictable situation during the operation, the abdominal wall puncture outfit which is already arranged on the operation table often lacks the actually needed model, causes difficult operation, increases the trauma of the patient, or is arranged in a redundant and useless way, and causes waste. In addition, the hard sheath tube on the isolation and protection bag for the laparoscope needs to be connected with the base of the abdominal wall puncture outfit for matching use, and the hard sheath tube on the bag also has various models with different thicknesses, so the same problem is also faced.
It is easy to understand that different requirements of the abdominal wall puncture outfit in clinic are different requirements of the abdominal wall puncture outfit due to the fact that a universal base is tried to be adopted according to different requirements of the matched connecting sheath tubes, the sheath tubes of different types needed in the laparoscopy can be connected at will, the cost can be reduced, and different requirements of a clinician on the abdominal wall puncture outfit in the operation can be met.
In view of the above, the base of the abdominal wall puncture outfit has a universal adapting interface function, and each type of sheath tube has a universal adapting socket function, i.e. one end of each type of sheath tube with different sizes has a universal adapting socket function, in other words, one type of base can be connected with various types of sheath tubes, so that doctors can randomly connect sheath tubes with required sizes according to clinical needs in the operation. In addition, because a plurality of hard sheath tubes with different thicknesses are connected on the soft bag for sealing, isolating and protecting the abdominal cavity in the laparoscopic surgery and a plurality of types of bases matched with the hard sheath tubes are also needed, the base of the abdominal wall puncture outfit is converted and arranged to have a function of a universal adapter interface, and the purpose that the sheath tubes with various types are connected with the base with one type can be realized.
The invention researches that in the early experiments, the threaded connection part of the sheath tube and the base is easy to rotate and loosen during the abdominal wall puncture, thereby influencing the operation.
At present, abdominal wall puncture outfits with different thickness models are all provided with corresponding puncture needle cores with different thickness models, in other words, one puncture needle core can only be matched with a sheath tube with one model, and due to the requirement of multiple models in clinical operation, a plurality of puncture needle cores are often required for one operation.
Because the abdominal wall puncture outfit is widely used in clinic, the using amount of the puncture needle core and the using amount of the base of the main structure are very large, and the problems of environmental protection and the like are involved in the medical waste treatment after the puncture outfit is used, the using amount of the puncture needle core and the using amount of the base can be reduced, so that the abdominal wall puncture outfit not only has important economic value, but also has important social value.
