Problems solved by technology
Due to the extremely high requirements on the accuracy and speed of the operation, and due to the serious defects of the existing implanter, when the stent is released, the inner sleeve of the implanter is often not fixed well, and the stent is placed inaccurately. Sometimes, the gap is very large, resulting in Serious adverse consequences, therefore, requires experienced experts to operate

Embodiment Construction
[0010] The method of esophageal stent placement is to determine the location of the tumor, the length of the esophageal stenosis, the degree of stenosis or the location of the fistula using radiation or gastroscopy, so as to determine the position of the stent, the length of the stent, and the inner diameter of the stent; The 2 cm stent for the tumor is placed under X-ray fluoroscopy or endoscopy, or a combination of the two methods.
[0011] (1) Insertion method under simple X-ray fluoroscopy: After determining the location of the lesion, mark it on the surface of the upper and lower edge of the lesion, insert the guide wire through the mouth under fluoroscopy, insert the stent implanter along the guide wire, and determine the position of the stent. When the position is in the center of the lesion, both ends exceed the lesion by 2 cm, slowly release the stent, complete the operation, and remove the inserter.
[0012] (2) Insertion method under simple gastroscopy: insert the g...

An esophageal stent implantation set rule comprises a nut (1), an adjusting clamping groove (2), a support (3), a fixing support (4), a bottom-end U-shaped groove (5), a bolt (6), a movable fixing support (7) and an upper-end U-shaped groove (8). The nut (1) is fixed in the adjusting clamping groove (2), the movable fixing support (7) is fixed with the bolt (6), and the upper-end U-shaped groove (8) is fixed on the movable fixing support (7). The fixing support (4) is arranged at the bottom end of the support (3), and the fixing support (4) is provided with the bottom-end U-shaped groove (5). According to the esophageal stent implantation set rule, no matter how an outer sleeve is moved, the position of an inner sleeve is fixed and unchanged all the time, the upper end of the support can be accurately positioned, so that the support is placed more simplified and 'folly', hence, the speed and accuracy for placing the support are improved, and the success rate of operations is obviously improved.
Description
technical field [0001] The invention relates to a medical device, in particular to a positioning ruler for placing an esophageal stent. Background technique [0002] Esophageal stent implantation has very high technical requirements. The position of the stent must be placed accurately. When withdrawing the outer sleeve of the pusher, the pusher must not move as a whole. In addition, the operation process should be as simple and fast as possible to reduce the operation time. Due to the extremely high requirements on the accuracy and speed of the operation, and due to the serious defects of the existing implanter, when the stent is released, the inner sleeve of the implanter is often not fixed well, and the stent is placed inaccurately. Sometimes, the gap is very large, resulting in Serious adverse consequences, therefore, requires experienced specialists to operate. Contents of the invention [0003] A positioning ruler for placing an esophageal stent includes: a nut, an a...
