Description
Technical Field
The present invention relates to a surgical instrument for minimally invasive surgery, such as endoscopic or laparoscopic surgery, and more particularly to a surgical instrument for piercing tissue, such as a puncture instrument.
Background
Laparoscopic surgery is currently the most widely used minimally invasive surgical procedure in clinical practice. In the operation, a laparoscope puncture outfit is used to puncture the body wall (chest, abdomen, waist and other parts) of a human body through the skin, the front end of a sheath tube of the puncture outfit is kept in the body cavities of an abdominal cavity, a thoracic cavity or a posterior abdominal cavity and the like, and then a surgical instrument is placed in a channel in the puncture sheath tube to carry out corresponding operation on the tissues and organs in the body cavities. The laparoscope puncture outfit is an instrument which must be used in the operation, the prior laparoscope puncture outfit has no effective fixing device after the sheath tube is punctured into a body cavity, and the puncture sheath tube is often separated from the body and goes deep into the body in the operation process. The puncture outfit sheath is placed too deeply, so that the risk of damaging visceral organs is caused, the visual field of an endoscope can be shielded, and the operation of surgical instruments is difficult, such as various forceps, clamps, ultrasonic knife heads, needle holders and the like can not be opened; the puncture outfit sheath tube is frequently taken out, so that an operator has to repeatedly puncture and place the cannula, the operation progress and quality are seriously influenced, and the trauma of a patient is aggravated. In addition, in laparoscopic surgery, carbon dioxide gas is required to be filled into the body cavity of a human body to expand the body cavity so as to facilitate the operation of surgical instruments. As a large gap can exist between the sheath tube of the puncture outfit currently used and the body wall puncture channel, the leakage of gas in the cavity is easy to cause. The body cavity is decompressed and collapsed due to a large amount of gas leakage, and the operation is seriously disturbed; the overflowed gas enters the subcutaneous loose fat tissue gap to form extensive subcutaneous emphysema, which increases the pain of the patient.
Currently, the most clinically applied puncture device sheath tube fixing measure is a skin suture method, namely, a method for fixing the puncture device sheath tube by knotting a suture after the suture passes through a side hole preset on the wall of the puncture device tube after the suture is sewn on the skin of a puncture site. The fixing mode is simple and convenient, can cut off and really prevent the sheath from being separated, but can not solve the problems that the sheath is placed too deeply and gas leaks outside. Aiming at the current situation that the puncture outfit used in the laparoscopic surgery lacks perfect fixing measures, different researchers design a plurality of puncture outfit auxiliary fixing structures or devices with fixing functions. For example, in the "laparoscope puncture cannula fixing seat" of the chinese utility model with patent number ZL201520070627.4 (publication number CN204428128U), the fixing seat includes an elastic rubber fixing disk which can be sleeved outside the sheath of the puncture device, when in use, the disk and the sheath are fixed relatively by the elastic tightening action of the rubber material, and the disk bottom and the skin of the puncture site of the body wall are fixed by suture. Or the Chinese utility model 'a laparoscope puncture outfit positioning snap ring' adopting the similar external fixing method, such as patent number ZL201420300864.0(CN203915028U), discloses the relative fixing between the puncture outfit sheath tube and the external fixing device by bolts, the design of the external fixing method can play a certain role in preventing the puncture outfit sheath tube from being placed too deeply and/or getting out, but the puncture outfit sheath tube is repeatedly twisted and pushed and pulled in the actual operation, the sheath tube and the fixing device of the outer sleeve still have a large risk of getting out, and the outer sleeve fixing device must limit the rotation angle of the puncture outfit sheath tube to a certain extent, thereby interfering the operation of surgical instruments, which is particularly remarkable when a relatively deep and far body cavity, such as a posterior abdominal cavity instrument is operated. Therefore, after the puncture outfit of the Chinese utility model patent with the patent number ZL201520146655.X (the publication number is CN204581447U) enters the abdominal cavity, gas or liquid is filled into the inflation/liquid pipeline through the inflation/liquid port to expand the saccule, thereby achieving the purpose of fixing the apparatus; the puncture outfit can expand the saccule by filling gas or liquid after entering the abdominal cavity, the puncture outfit is provided with the inflation/liquid port and the inflation/liquid pipeline, so that the diameter of the sheath tube of the puncture outfit is easily increased, and meanwhile, the manufacturing cost and the use cost of the puncture outfit with the saccule are higher, so that the prior puncture outfit needs to be further improved.
