A transumbilical multi-hole laparoscopic puncture component

Abstract

The invention discloses a transumbilical multi-hole laparoscopic puncture assembly, which comprises an operating part, a first connecting sheath arranged inside the operating part and a connecting seat arranged at the bottom of the operating part, and the first connecting sheath is connected with the connecting seat through the connecting seat. The operation part is connected, the bottom end of the first connecting sheath tube is connected with a puncture needle through the third connecting sheath tube, the inside of the puncture needle is provided with an imaging mechanism, and the outside of the third connecting sheath tube is provided with a support body, and the support body Adjustment mechanisms are provided on both sides. The invention adjusts the telescopic length of the rack on the support body by sliding the connecting plate inside the support body, thereby adjusting the working position of the first connecting body, connecting the connecting part with the biaxial connecting body through a tightening belt, and rotating the biaxial Adjust the upper and lower working positions of the connecting part toward the column of the connecting body, and adjust the front and rear working positions of the connecting part by rotating the arc surface of the biaxial connecting body, so as to connect the operating part and the connecting part to each other, and it is also convenient to adjust the operating part and the connecting part. Operating space between joints.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a transumbilical multi-hole laparoscopic puncture component and a use method. Background technique [0002] With the continuous innovation and development of minimally invasive medical surgery, more and more attention has been paid to the scarless surgery of the patient's appearance. The common single hole scarless surgery through the umbilical abdominal wall needs to create a rather large wound on or near the patient's navel for surgery. , due to the use of single-hole laparoscopic surgery, the phenomenon of mutual influence between surgical instruments is inevitable. If the surgery further expands the wound, it may have a serious impact on the patient's postoperative recovery, which is not easy to heal, and cannot Be minimally invasive.

[0002] With the continuous innovation and development of minimally invasive medical surgery, more and more attention is paid to the scarless surgery of the patient's appearance. The common single hole scarless surgery through the umbilical abdominal wall needs to create a rather large wound on or near the patient's navel for surgery. , due to the use of single-hole laparoscopic surgery, the phenomenon of mutual influence between surgical instruments is inevitable. If the surgery further expands the wound, it may have a serious impact on the patient's postoperative recovery, which is not easy to heal, and cannot minimally invasive

[0003] In the prior art, transumbilical puncture as in abdominal surgery generally includes two methods, one is to cut a single incision of about 2 cm in the umbilicus, and insert multiple casings into a single opening for operation; Multiple incisions are made around the navel, and a cannula is placed through each incision for surgery. During the operation of these two methods, multiple independent puncture components are required to cooperate with each other. During the operation, when operating one of the puncture components , the rest of the puncture components require additional medical staff to assist in grasping, which is likely to cause excessive manpower consumption. If the operation is not assisted by additional medical staff, the multiple puncture components will easily slip into the patient's abdominal cavity due to unstable fixation and affect the operation.
