Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a stoma positioning ruler. Background Art

[0002] A surgical stoma locator is a tool used to locate and measure the position and size of the incision during surgery. It usually consists of a main body and some measuring rulers, which can help doctors accurately determine the position and length of the surgical incision. Surgical stoma locators are often used in surgical operations to ensure the accuracy and consistency of surgical incisions to ensure the success and safety of the surgical operation.

[0003] In the Chinese patent with publication number CN210932145U, a stoma positioning ruler is mentioned, which uses two angle-adjustable scales, and slides a positioning ruler on each of the two scales, places the fixed axis at the intersection of the two scales at the patient's umbilicus, and adjusts the angle between the scales so that the two scales point from the umbilicus to the direction of the pubic symphysis and the direction of the anterior superior iliac spine, respectively, moves the sliders that the positioning ruler and the scales are slidably connected, so that the two sliders are located at the corresponding positions of the pubic symphysis and the anterior superior iliac spine, respectively, and a triangle is formed by the fixed axis and the two sliders, and then the positioning ruler is pointed to the midpoint of the opposite sides of the triangle, at this time, the intersection of the two positioning rulers is the preset stoma position. This fills the gap in the prior art that there is no special tool for the triangular stoma positioning method. The stoma positioning ruler has a simple structure, is easy to operate, and has accurate positioning, which can facilitate medical staff to easily and quickly perform preoperative positioning of the intestinal stoma.

[0004] The stoma positioning ruler in the above-mentioned comparative patent has a simple structure, is easy to operate, and has precise positioning, and can facilitate medical staff to easily and quickly perform preoperative positioning of the intestinal stoma. However, during use, the positioning ruler cannot be fixed and limited on the patient's skin, which causes the positioning ruler to easily shift in position during measurement, and when the marking ruler moves to the middle part of the positioning ruler, the marking ruler cannot be fixed and limited, thereby affecting the accuracy of positioning.

The abutment rod 403 is inserted through the inside of the sleeve seat 401, and the sleeve seat 401 is slidably connected to the outside of the second positioning ruler 3.

[0033] Specifically, through the stretching operation of the abutting rod 403 , the elasticity between the abutting rod 403 and the tension spring 402 can be extended and retracted, so that the abutting rod 403 abuts and fixes the outside of the second positioning ruler 3 .

[0034] As can be seen from the above, when the sleeve seat 401 moves to the middle position on the first positioning ruler 1 and the second positioning ruler 3, the elastic expansion and contraction between the abutment rod 403 and the tension spring 402 can make the abutment rod 403 abut against the outside of the second positioning ruler 3, so as to abut and fix the sleeve seat 401 on the outside of the second positioning ruler 3, and then through the stretching operation of the positioning rope 504, the positioning rope 504 is stretched to the bottom of the corresponding positioning ruler. At this time, the intersection position between the two positioning ropes 504 is the preset stoma position, and the setting of the winding spring 501 facilitates the elastic automatic winding of the positioning rope 504.
