Description

Technical Field

[0050] The method of applying the endoscopic surgical pad comprises the following steps:

[0051] Step 1. The endoscopic surgical gasket is in a contracted state. The endoscopic surgical gasket is kept in a contracted state before use:

[0052] ①Please refer to the attached Figure 1 , 2 , the gasket limiting ring 9 and the gasket limiting ring buckle 16 are fixed by a buckle structure, so that the gasket limiting tube 8 is sleeved outside the gasket 5, so that the gasket 5 remains in a contracted state;

[0053] ②Please refer to the attached Figure 2 , 610, the delivery pipe 3 is connected to the long curved arm 6 of the fixture through the connecting ring 4, the first tenon 18 on the connecting ring 4 is clamped in the first limiting ring 24 at the tail of the long curved arm 6 of the fixture, and the second tenon 19 on the connecting ring 4 is clamped in the second limiting ring 17 at the head of the delivery pipe 3.

[0054] ③Please refer to the attached Figure 2 The short arm 7 of the fixer is sleeved in the long curved arm 6 of the fixer, the long curved arm tooth comb 22 and the short arm tooth comb 25 are in an unclosed state, and the pushing block 13 is located in the short arm pushing groove 28.

[0055] Step 2. Deployment of the endoscopic surgical gasket. After the endoscopic surgical gasket is delivered to the body cavity through the endoscopic biopsy channel, it must first be deployed in the body cavity:

[0056] Please see attached Figure 3 , 9 , open the gasket limiting buckle 16, separate the gasket limiting ring 9 from the gasket limiting ring buckle, pull the gasket limiting tube 8 backward to unfold the gasket 5. Since the gasket 5 is a memory metal wire woven skeleton, when the gasket limiting tube 8 is pulled backward to expose the gasket 5, the gasket 5 automatically unfolds into a sheet.

[0057] Step 3. Fixing of endoscopic surgical gasket: fix the unfolded gasket on the surgical suture:

[0058] Please see attached Figure 3 , 5 , 7, 8, 9, 11, 12, 13, hang the long curved arm 6 of the fixer on the surgical suture, push the pusher 1 forward, make the short arm 7 of the fixer slide forward in the long curved arm 6 of the fixer, complete the engagement of the long curved arm tooth comb 22 and the short arm tooth comb 25, make the endoscopic surgical gasket pad between the surgical suture and the human tissue, and complete the fixation. In this process, it is necessary to push the thumb ring 10 forward, push the pushing bar 11 forward to the top of the pushing bar limiting groove 15, at this time, the pushing block 13 pushes the short arm 7 of the fixer forward, and the long curved arm limiting protrusion 23 slides in the slide rail 26 and slides into the short arm limiting groove 27, so that the position of the short arm 7 of the fixer and the long curved arm 6 of the fixer is fixed.

[0059] Step 4. Release of the endoscopic surgical gasket. After the endoscopic surgical gasket is fixed, the delivery system and the gasket system need to be separated and released:

[0060] Please see attached Figure 4 , 5 6. Pull the thumb ring 10 backward to drive the push block 13 into the push block separation groove 20, and continue to pull backward to make the first tenon 18 disengage from the first limiting ring 24, thereby completing the release of the delivery system and the gasket system, leaving the gasket system in the body cavity, and withdrawing the delivery system through the biopsy channel of the endoscope.

[0061] Example: Please see the attached Figure 1-13 As shown, during the percutaneous endoscopic gastrostomy surgery, the first physician passes the surgical suture through the abdominal wall to the gastric cavity through the gastric wall fixator in the gastrostomy kit, leaving a loose semi-circular surgical suture in the gastric cavity, and the second physician delivers the endoscopic surgical gasket 5 to the gastric cavity along the endoscopic biopsy channel, and the nurse inserts the thumb of the right hand into the thumb ring 10, and the index finger and middle finger of the right hand into the handle finger rings 14 on both sides of the handle 2 to fix the handle 2, opens the gasket limiting ring buckle 16, separates the gasket limiting ring 9 from the gasket limiting ring buckle 16, pulls the gasket limiting ring 9 backward to drive the gasket limiting tube 8 to move backward, and the gasket 5 slips out of the gasket limiting tube 8, completing the release of the endoscopic surgical gasket 5;

[0062] The second doctor adjusts the endoscope so that the exposed long curved arm 6 of the fixator is hung on the semi-circular surgical suture, pushes the thumb ring 10 forward, makes the pushing block 13 enter the short arm pushing groove 28, pushes the short arm 7 of the fixator to slide along the slide rail 26, and the long curved arm limiting protrusion 23 just slides into the short arm limiting groove 27, the long curved arm tooth comb 22 just bites with the short arm tooth comb 25, and the short arm 7 of the fixator and the long curved arm 6 of the fixator form a closed ring, completing the fixation of the endoscopic surgical gasket 5;

[0063] Then the endoscopic surgical gasket 5 is fixed on the surgical suture, the doctor one tightens the surgical suture outside the body, the doctor two adjusts the endoscopic surgical gasket 5 to a satisfactory position through the cooperation of the endoscope, the doctor one knots the surgical suture outside the body to fix it, the nurse pulls the thumb ring 10 backwards, drives the push block 13 to retreat to the push block separation groove 20, and then pulls it back hard to make the first tenon 18 disengage from the first limiting ring 24 and retreat to the second limiting ring 17, completing the separation of the endoscopic surgical gasket 5, the doctor two pulls the remaining part out of the endoscopic biopsy channel, checks the position of the suture and the endoscopic surgical gasket 5, the gasket 5 can be in various forms such as umbrella-shaped release, folding-shaped release, spiral-shaped release, petal-shaped release, etc., to adapt to different surgical requirements, the gasket 5 is coated with There are slow-release hemostatic coatings and slow-release antibiotic coatings, which can slowly release hemostatic drugs and antibiotic drugs to reduce bleeding and infection at the fistula. The tail end of the long curved arm 6 of the fixator is provided with a first limiting ring 24. When removing the stitches two weeks after the gastrostomy operation, the first doctor first clamps the first limiting ring 24 with a foreign body forceps under the endoscope, and the second doctor cuts and removes the sutures. The first doctor removes the endoscopic gasket 5 through the esophagus under the endoscope. However, when the stitches are removed for some patients with esophageal tumors, the esophagus is already severely narrowed, and the endoscopic gasket 5 cannot be removed through the esophagus. At this time, the endoscopic gasket 5 will fall into the gastric cavity after the stitches are removed, and will be excreted with feces through the intestine. The patient can connect the built-in GPS positioning system through the mobile phone to observe the position of the endoscopic gasket 5 and whether it is excreted.

[0064] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
