Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing cannula trocar does not have the function of limiting the moving distance of the puncture tube, which leads to the fact that when the puncture tube is inserted too deep, it is easy to cause damage to the internal organs of the patient. It has the function of rationalizing and fixing the puncture needle, which is not conducive to the rapid opening of the puncture operation channel, and a thrust-type cannula puncturer is proposed

Abstract

The invention discloses a thrust type cannula puncture outfit, and relates to the technical field of medical instruments. The thrust type cannula puncture outfit comprises a puncture tube, the outer side of the puncture tube is sleeved with an anti-injury pad, the outer side of the anti-injury pad is bonded with a positioning ring, the outer side of the positioning ring is connected with a compression spring through injection molding, and one side of the tail end of the compression spring is provided with a thrust plate; four sets of threaded holes are formed in the inner side of the thrust plate, studs are in threaded connection with the inner sides of the threaded holes, and two sets of fixing blocks are fixedly connected to the upper portion of the inner side of the puncture tube. According to the puncture outfit, due to the fact that the thrust plate is installed on the outer side of the puncture tube, the downward insertion depth of the puncture tube can be effectively limited bythe thrust plate, and therefore the situation that the internal organs of a patient are damaged due to the fact that the downward insertion depth of the puncture tube is too large can be effectively prevented; furthermore, the inner side of the thrust plate is in threaded connection with the stud, and the user can conveniently adjust the position height of the thrust plate on the puncture tube according to the downward insertion depth.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a thrust type cannula puncturer. Background technique [0002] The puncture device is used to establish a channel for endoscopes and surgical instruments to enter and exit the body after puncturing the body wall in laparoscopic surgery, and can deliver gas to the body. It is suitable for establishing and maintaining access to the abdominal cavity or in general surgery, thoracic surgery, gynecology and urology The working channel of the chest. [0003] The existing cannula trocars do not have the function of limiting the moving distance of the puncture tube, which leads to the fact that when the puncture tube is inserted too deep, it is easy to cause damage to the internal organs of the patient. In addition, it does not have the function of rationally fixing the puncture needle , And then it is not conducive to the rapid opening of the puncture operation channel. Co...
