Description

Technical Field

[0001] The invention relates to a surgical auxiliary device, which is applied to the establishment of internal and external passages of the abdominal wall during laparoscopic surgery. Background Art

[0002] Laparoscopic surgery is to insert a sheath of an abdominal wall puncture device into the abdominal wall to establish a surgical channel, inject high-pressure gas into the abdominal cavity to expand the abdominal cavity and create space, and insert a columnar laparoscope through the hollow tubular structure of the abdominal wall puncture device to observe the intra-abdominal surgical process, and use long-handled surgical instruments to enter the abdominal cavity through the hollow tubular structure of the abdominal wall puncture device for surgical operations. The abdominal wall puncture hole is tiny, and it is also called "keyhole" surgery. Therefore, compared with traditional open surgery, the patient's abdominal wall surgery damage is small and the recovery is fast. Obviously, the abdominal wall puncture device is an indispensable auxiliary device for laparoscopic surgery.

[0003] The main structure of the abdominal wall puncture device is the base and the sheath. The base includes a three-way tube air injection valve, an air blocking valve, a rear cover sealing seat and other complex structures. It is the main structure of the abdominal wall puncture device. The base is always kept outside the body during the operation and does not enter the abdominal wall and abdominal cavity. The sheath of the abdominal wall puncture device is a tubular structure with a simple structure. It enters the abdominal wall and abdominal cavity during the operation. According to the thickness of the sheath, the abdominal wall puncture device can be divided into different model standards such as 3 mm, 5 mm, 10 mm, 12 mm, 15 mm, etc. The thicker the sheath, the thicker the abdominal wall. The greater the trauma to the abdominal wall, the more obese patients with thick abdominal wall need a longer sheath model. Therefore, there are many types of abdominal wall puncture devices. Clinically, different types of abdominal wall puncture devices are selected according to the patient's fatness, the type of disease, and the adaptability during the operation. Since the base and sheath of the abdominal wall puncture device are currently a one-to-one integrated structure, in order to meet the clinical needs for different types of sheaths, it is often necessary to configure multiple types of abdominal wall puncture devices, and each type of abdominal wall puncture device is a sheath fixed to a base. However, even so, due to the unpredictable situation during the operation, it is often the case that the abdominal wall puncture devices already configured on the operating table either lack the actual required model, causing surgical difficulties, or increasing the patient's trauma, or are redundant and useless, causing waste. In addition, the hard sheath on the bag of the laparoscopic isolation and protection bag needs to be connected to the base of the abdominal wall puncture device for matching use. Since there are also multiple models of hard sheaths with different thicknesses on the bag, they also face the same problem.

[0004] It is not difficult to understand that the different clinical demands for abdominal wall puncture devices are due to the different demands for their matching connecting sheaths. Trying to use a universal base that can arbitrarily connect different types of sheaths required during laparoscopic surgery can reduce costs and meet the different demands of clinicians for abdominal wall puncture devices during surgery.

[0005] In view of this, the present invention sets the base of the abdominal wall puncture device with a universal adapter interface function, and each type of sheath tube is set with a universal adapter socket function, that is, one end of sheath tubes of different types, such as thick, thin, long, and short, has a universal adapter socket function. In other words, one type of base can be connected to multiple types of sheath tubes, so during surgery, the doctor can freely connect the required type of sheath tube according to clinical needs. In addition, since multiple hard sheath tubes of different thicknesses are connected to the soft bag used for closed isolation and protection in the abdominal cavity during laparoscopic surgery, multiple types of bases that match them are also required. The present invention sets the base conversion of the abdominal wall puncture device with a universal adapter interface function, so that multiple types of sheath tubes can be connected to one type of base.

[0006] Since the sheath encounters resistance when being inserted into the abdominal wall, it needs to be rotated forcefully to be able to puncture into the abdominal cavity. In the early experiments of the present invention, it was found that the threaded connection between the sheath and the base is very easy to rotate and loosen during abdominal wall puncture, affecting the surgical operation. Obviously, the threaded connection between the sheath and the base is a weak link when used for abdominal wall puncture and needs to be strengthened and stabilized.

[0007] At present, abdominal wall puncture devices of different thicknesses are equipped with corresponding puncture needle cores of different thicknesses. In other words, one puncture needle core can only be used with one type of sheath. Due to the need for multiple types of puncture needle cores during clinical surgery, one operation often requires multiple puncture needle cores.

[0008] Since abdominal wall puncture devices are widely used in clinical practice, the consumption of puncture needle cores and bases of the main structure is very large, and the disposal of medical waste after use involves environmental protection and other issues. Therefore, if the consumption of puncture needle cores and bases can be reduced, it not only has important economic value, but also has important social value. Summary of the invention
