Application method of puncture device

Abstract

The invention discloses an application method of a puncture device. The application method includes the following steps: extending a puncture core component below subcutaneous tissue from a cannula ofa cannula component, and rotating a rotary knob to form an accommodating space; upwardly moving the puncture core component to locate the to-be-sutured subcutaneous tissue in the accommodating space;pressing down a suturing button, and pushing a suture needle to pass through the subcutaneous tissue to drive the tail of a suture line to pass through the subcutaneous tissue; upwardly moving the puncture device to draw out the tail of the suture line from a puncture hole; knotting the tail of the suture line, and removing the surplus suture line. According to the application method of the puncture device, the puncture hole is sutured by rotating the rotary knob and pressing down the suturing button; operations are simple, and expansion of the puncture hole and addition of an additional surgical instrument are not needed; the puncturing effect can be achieved, the puncture hole can be sutured in the narrow puncture hole, and puncture hernias caused by puncture holes of minimally invasivesurgery can be effectively avoided.

Description

Technical field [0001] The invention relates to a method of using a puncture puncture device. Background technique [0002] Laparoscopic surgery has been widely accepted in surgical operations. Compared with traditional open surgery, laparoscopic surgery has many advantages, including reduced damage, faster healing, and reduced risk of infection. In abdominal cavity inspection, abdominal cavity surgery and other minimally invasive or surgical operations, the trocar is an indispensable surgical instrument. The trocar can establish an access channel in the abdominal wall of the human body so that staplers or other surgical instruments (such as endoscopes, scissors, guide wires, catheters, filters, stents, etc.) can enter the abdominal cavity and provide a channel for gas to enter and exit. Control the pneumoperitoneum required for surgery for examination or surgery. The trocar is a surgical instrument used to establish an artificial passage into the body cavity in laparoscopic su...

Problems solved by technology

When it is necessary to suture the puncture hole of a patient, especially the puncture hole of an obese patient, only a stapler specially used for suturing the puncture hole can be used, but this requires additional surgical instruments, the suturing cost is high, and there are many surgical instruments and inconvenient operation; And, the stapler that specially sutures the puncture hole has a complex structure and is inconvenient to use
