Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an intestinal stoma and anal dilation nursing device. Background Art

[0002] A colostomy is an artificial opening made in the abdominal wall by a surgeon to treat certain intestinal diseases (such as rectal cancer, ulcerative colitis, etc.). A section of the intestine is pulled out of the opening, flipped over and sewed to the abdominal wall, thus forming a colostomy.

[0003] Chinese patent publication number CN219250618U discloses a colostomy anal dilation care device. By setting an expansion component, four small electric push rods drive the corresponding four expansion side plates to move, slowly expanding the patient's colostomy. It is simple, convenient and effective to use.

[0004] However, compared with the existing technology and comparative documents, the existing colostomy anal dilation care device uses an electric device to drive the expansion plate to expand the colostomy during use. However, during the expansion process, the movement distance of the expansion plate driven by the electric device cannot be effectively controlled, and the accuracy is poor. Utility Model Content

[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0022] like Figure 1-Figure 3As shown, the intestinal stoma anal dilation nursing device provided in this embodiment includes a rod body 1, a gripping rod 2 is installed at the bottom end of the rod body 1, which is convenient for the staff to take the gripping rod 2 to use the device, four groups of expansion plates 3 are set on the outside of the rod body 1, the expansion plates 3 are used to expand the anus, and an expansion mechanism 4 is installed in the expansion plate 3. The expansion mechanism 4 includes a connecting rod 401 connected to the expansion plate 3, and the connecting rod 401 can drive the expansion plate 3 to move. A guide seat 402 is installed at one end of the connecting rod 401, and the guide seat 402 is The force drives the expansion plate 3 to move through the connecting rod 401. A guide cone 403 is arranged between the guide seats 402. The guide cone 403 can apply force to the guide seat 402 during the lifting process. A bearing 404 is installed in the middle of the bottom end of the guide cone 403 to facilitate the connection between the screw 405 and the guide cone 403 through the bearing 404. The screw 405 is fixed in the bearing 404. The staff adjusts the expansion plate 3 by turning the screw 405. The inner wall of the guide seat 402 has a conical structure.

[0023] like Figure 1-Figure 3 As shown, both the top and bottom ends of the expansion plate 3 are inclined structures, and the expansion plate 3 fits well with the rod body 1, which can improve the comfort when the rod body 1 enters the patient's body.

[0024] like Figure 1-Figure 2 As shown, a guide rod 5 is symmetrically installed at the bottom end of the guide cone 403, and the guide rod 5 is slidably connected to the rod body 1, so that the guide cone 403 can be guided by the guide rod 5.

[0025] like Figure 1-Figure 2 As shown, a guide hole 9 is symmetrically opened at the bottom end of the rod body 1, and the guide hole 9 corresponds to the position of the guide rod 5, and the guide hole 9 can be used to limit the guide rod 5.

[0026] like Figure 1-Figure 2 As shown, a return spring 6 is provided on the outside of the connecting rod 401 , and one end of the return spring 6 is fixed to the inner wall of the rod body 1 , so that the expansion board 3 can be returned to its original position by the return spring 6 after use.

[0027] like Figure 1-Figure 3 As shown, a bottom plate 7 is provided at the bottom end of the screw rod 405 , and the bottom plate 7 is connected to the screw rod 405 with bolts, so that the staff can drive the screw rod 405 to rotate through the bottom plate 7 .

[0029] The working principle of this device: When this device is used, the staff takes the holding rod 2 and inserts the rod body 1 into the patient's enterostomy. After the insertion is completed, the staff drives the screw 405 to rotate through the bottom plate 7. The screw 405 can rotate along the rod body 1 and drive the guide cone 403 to move through the bearing 404. The guide cone 403 contacts the guide seat 402 of the conical structure during the movement. When the guide seat 402 contacts the guide cone 403, it is forced to drive the four groups of expansion plates 3 to move outward synchronously through the connecting rod 401 to expand the anus. The rotation of the screw 405 makes it convenient for the staff to make precise adjustments and improve the accuracy. During the lifting and lowering of the guide cone 403, the guide rod 5 can move along the guide hole 9, thereby ensuring the vertical lifting and lowering of the guide cone 403, and the connecting rod 401 can be guided by the through hole 8. After use, the expansion plate 3 is reset by the reset spring 6.
