Abstract
Description
Technical Field
[0001] This invention relates to the field of biomedical device technology, and in particular to an automatic cutting device for an enterostomy chassis. Background Technology
[0002] After enterostomy, patients need to wear an ostomy bag on their abdomen, which is fixed to the skin by a stoma base plate. Because the shape, size, and location of the stoma vary from patient to patient, the center hole of the stoma base plate needs to be cut according to the individual's condition before use. Clinical surveys show that over 65% of enterostomies have complex morphological features such as irregular protrusions and tilt angles. When cutting the enterostomy base plate, the length and width of the stoma root are first measured manually with a stoma ruler to complete the two-dimensional planar data acquisition of the enterostomy, which cannot obtain three-dimensional morphological information. Then, the enterostomy base plate is cut manually or with a semi-automatic cutting machine. Due to factors such as operator experience and hand stability, there are significant errors between the cut base plate and the stoma edge, leading to decreased stoma base plate sealing. Improper measurement or cutting can even cause inflammation and ulceration of the skin around the stoma, increasing the patient's suffering. Summary of the Invention

The cutting blade 34 is generally annular, and during the cutting process, the cutting blade 34 can rotate around its mounting axis. The pressing member 35 is generally a circular plate, and during the cutting process of the cutting assembly 3, the pressing member 35 can press against the clamping assembly 4.
[0036] Also refer to Figures 5 to 8The second mounting groove 14 has a mounting hole 15 at its center. The clamping assembly 4 is mounted on the lower housing 11 and extends out of the mounting hole 15. The clamping assembly 4 includes a mounting base 47, a sleeve 41, a pusher 42, a resetter 43, a clamping member 44, a first elastic member 45, and a second elastic member 46. The mounting base 47 is mounted on the lower side of the second mounting groove 14. Preferably, the mounting base 47 is located between the lower housing 11 and the battery assembly 12. The mounting base 47 has two annular grooves. The upper end of the mounting base 47 has a flange extending radially outward, and the flange has multiple openings. Screws pass through the openings to mount the mounting base 47 on the lower side of the second mounting groove 14. The sleeve 41 is generally a hollow cylinder with openings at both ends. The sleeve 41 has a through hole 411 at its center. Preferably, the through hole 411 is a stepped hole. The sleeve 41 is partially inserted into the mounting hole 15 of the lower assembly 1. The lower end of the sleeve 41 is provided with an annular protrusion 413 extending radially outward. The protrusion 413 is located between the mounting base 47 and the mounting hole 15. A side opening 412 is provided on the portion of the sleeve 41 that protrudes from the mounting hole 15, and the side opening 412 penetrates the sleeve 41 radially.
[0037] A pusher 42 is fitted into the through hole 411 of the mounting base 47 and extends from the upper end of the mounting base 47. The pusher 42 includes a cylindrical portion 421 and a tapered portion 422 disposed on the lower end of the cylindrical portion 421. The diameter of the tapered portion 422 gradually decreases from top to bottom. A reset member 43 is mounted on the end of the tapered portion 422 away from the cylindrical portion, and the reset member 43 is also fitted into the through hole 411 of the mounting base 47. The diameter of the reset member 43 is larger than the diameter of the cylindrical portion of the pusher 42. The upper end of the reset member 43 is provided with a notch 431, and the two sides of the notch 431 are respectively configured as first inclined surfaces 432. The distance between the two first inclined surfaces 432 gradually decreases from top to bottom. Two clamping members 44 engage in the side opening 412 and are respectively located on both sides of the tapered portion 422. The clamping member 44 has a second inclined surface 442 on one side adjacent to the conical portion 422, which is tangent to the conical portion 422. The clamping member 44 has a downward-facing groove at its center, and a third inclined surface 443 is formed on one side of the groove adjacent to the conical portion 422, which fits against the first inclined surface 432. When the pushing member 42 is pushed downward by the pressing member 35, the resetting member 43 moves downward simultaneously. Under the action of the cylindrical portion 421 and the second inclined surface 442, the clamping member 44 moves outward. When the sleeve 41 is pushed downward by the pressing member 35, it causes the clamping member 44 to move downward, clamping the enterostomy base plate 6 between the clamping member 44 and the second mounting groove 14.
[0038] The first elastic element 45 is located between the mounting base 47 and the resetting element 43. Preferably, one end of the first elastic element 45 is installed in an annular groove of the mounting base 47, and the other end abuts against the lower end of the resetting element 43. The second elastic element 46 is located between the mounting base 47 and the sleeve 41. One end of the second elastic element 46 is installed in another annular groove of the mounting base 47, and the other end abuts against the lower end of the sleeve 41. Preferably, the first elastic element 45 and the second elastic element 46 are springs. After the enterostomy base plate 6 is cut, the pressing element 35 releases the pressure on the sleeve 41 and the pushing element 42. The sleeve 41 moves upward under the action of the second elastic element 46, and the resetting element 43 and the pushing element 42 move upward under the action of the first elastic element 45, driving the clamping element 44 to move upward. At the same time, under the action of the first inclined surface 432 and the third inclined surface 443, the clamping element 44 returns to the side opening 412, making it convenient for the user to remove the cut enterostomy base plate 6 from the second mounting groove 14. In addition, it is conceivable that the lower housing 11 is also provided with a drawer for storing the enterostomy tray 6.
[0039] In use, the automatic cutting device for the enterostomy base plate is opened. The user takes out the 3D scanner 5 from the first mounting slot 13 and places the enterostomy base plate 6 to be cut into the second mounting slot 14. The central opening of the enterostomy base plate 6 passes through the clamping component 4. The user then holds the 3D scanner 5 to scan the enterostomy and obtain 3D data about the enterostomy. The control component receives the data from the 3D scanner 5 and generates the required cutting path based on the received data. The user confirms the generated cutting path on the display screen 22 and confirms the start and end positions of the cutting path. The user drives the cutting component 3 to perform the corresponding cutting work through the button 23. Under the control of the control component, component 3 moves the cutting scissors 34 to the starting position of the cutting path via the three-axis moving component 31. During the movement of the cutting scissors 34, the pressing component 35 is simultaneously moved downward onto the clamping component 4, the pushing component 42 is pushed downward by the pressing component 35, and the resetting component 43 moves downward at the same time. Under the action of the cylindrical part 421 and the second inclined surface 442, the clamping component 44 moves outward; the sleeve 41 is pushed downward by the pressing component 35, which in turn moves the clamping component 44 downward, clamping the ostomy base plate 6 between the clamping component 44 and the second mounting groove 14. Then, under the control of the control component, the cutting component 3 cuts the ostomy base plate 6 along the required cutting path. Preferably, during the cutting process, the motor 32 drives the cutting scissors 34 to rotate so as to cut more arc-shaped positions. After the cutting is completed, the three-axis moving assembly 31 drives the cutting blade and the pressing component 35 to move upward back into the third mounting groove 24. During this process, the pressing component 35 releases the pressure on the sleeve 41 and the pushing component 42. The sleeve 41 moves upward under the action of the second elastic component 46. The resetting component 43 and the pushing component 42 move upward under the action of the first elastic component 45, driving the clamping component 44 to move upward. At the same time, under the action of the first inclined surface 432 and the third inclined surface 443, the clamping component 44 returns to the side opening 412. The automatic cutting device for the ostomy chassis is opened to remove the cut ostomy chassis 6 from the second mounting groove 14.
