A highly airtight surgical channel with anti-leakage when inflated

Abstract

The invention discloses a highly airtight surgical channel with anti-leakage when inflated, which belongs to the technical field of medical appliances and comprises a channel inner tube, the outer wall of the channel inner tube is covered with a protective seat, and one side of the protective seat is It is connected with a placement seat, the other side of the protective seat is connected with an inflation mechanism, one side of the inflation mechanism is movably connected with a fitting mechanism, and the top of the placement seat is provided with an adjustment mechanism. In the present invention, the movement of the screw rod base can drive the measuring ruler to move, and the movement of the measuring ruler can be compared with the measuring groove on one side to assist the doctor to observe the depth of the tube, and the reciprocating screw rod can drive the measuring ruler to reset when it continues to rotate, and the measuring ruler can be reset by the reciprocating movement. The moving distance of the ruler can be used to judge the depth of the tube, which can drive the inner tube of the channel to move stably into the wound and out, avoiding the laceration caused by the doctor's hand shaking and the contact with the inner cavity of the wound, and can move the measuring ruler to judge the depth of the tube during rotation, reducing the cost of surgery. It is difficult to establish the channel, which significantly facilitates the work of doctors.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a highly airtight operation channel with anti-leakage when inflated. Background technique [0002] In the original technology, the surgical wound is large, which is prone to postoperative complications. With the development of science and technology, laparoscopic surgery is more and more widely used. After laparoscopic surgery, it has the advantages of small wound, short treatment time, and less pain for patients. The working sleeve of the laparoscope is inserted into the human body as a passage for the surgical instruments, and the doctor can send the laparoscope and surgical instruments into the human body through the working sleeve to realize disease diagnosis and surgical treatment. [0003] Most of the existing surgical channels are fixed and installed through the sleeve, and the sealing effect between the sleeve and the surgical wound is poor, which e...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the poor sealing effect of the cannula and the surgical wound, it is easy to cause cross-infection, and affect the subsequent availability of the device, and the insertion depth is limited due to the shielding of the protective device during insertion. It cannot be observed very well, and can only be observed by the surgeon when inserting, and the protective tube lacks the limit ability when inserting, so a high air-tight operation with anti-leakage when inflated is proposed aisle
