Description

Technical Field

[0001] The present invention relates to the technical field of medical device assisted measurement, and particularly to a stoma shaping device for stoma trimming of a stoma bag. Background Art

[0002] A stoma is caused by digestive system or urinary system diseases, and surgical treatment is required to separate the intestinal tract, and one end of the intestinal tract is led out to the body surface (the anus or urethra is moved to the abdominal wall) to form an opening; a stoma can achieve intestinal decompression, relieve obstruction, protect the anastomosis or injury of the distal intestinal tract, and promote the recovery of intestinal and urinary tract diseases; a stoma bag is a container for collecting human excreta, such as urine and feces; it is generally used for the collection and discharge of excreta of patients undergoing intestinal stoma surgery; the stoma bag has a cuttable opening to adapt to the stoma size and shape of different patients; in the actual use process, some stoma shapes are not circular, and when cutting, a stoma caliper should be used to measure the lengths in two directions (the transverse axis and longitudinal axis of the body) of the stoma respectively; then the two measured values are respectively enlarged by 1-2 mm and marked on the stoma chassis to avoid pinching the stoma, which may cause bleeding and necrosis of the mucosa; use a stoma curved scissors to cut according to the marks; avoid being too large or too small, as being too large will have a stimulating and damaging effect on the skin of the stoma; adjust the stoma inner diameter to make it closely fit with the skin around the stoma to form a fitting surrounding state. In summary, the following technical problems exist in the current stoma bag trimming process: when trimming the stoma bag, the circular groove on the stoma caliper is used to compare with the stoma, but the stoma is not always circular. For a non-circular stoma, medical staff can only estimate the concave or convex shape within the corresponding size, resulting in the trimming shape of the stoma bag not fitting the stoma shape.

The air pushing semi-column and the air pushing semi-plate are located at half of the air pushing hole. The working semi-column and the working semi-plate on one combined frame and the air pushing semi-column and the air pushing semi-plate are on the same side. When the working semi-columns, the working semi-plates, the air pushing semi-columns, and the air pushing semi-plates on the two combined frames are all on the same side, the working semi-plates of the two combined frames face each other, and the air pushing semi-plates of the two combined frames face each other.

[0014] The beneficial effects of the present invention: A stoma shaping device for stoma bag trimming. When in use, first flip the combining frame on one side, and then align the combining frames on both sides. At this time, the working part and the air pushing part between the two combining frames are opposite to each other, but the working part and the air pushing part between the two combining frames are respectively distributed on the upper and lower sides. Combine the two combining frames, and the clamping ball is clamped with the clamping groove. Through the working holes on the same side, move the dial block in the working hole towards the combining frame on the opposite side. During the movement of the dial block, after the limiting block on the working half plate cooperates with the inclined plane of the inclined plane block, the limiting block cooperates with the vertical plane of the inclined plane block. The inclined plane block moves up and down through the upper compression spring, separating the two combining frames. The limiting block pulls the inclined plane block, so that the moving plug stores gas in the air pushing hole. During the pulling process, the connecting frame cooperates with the inclined plane of the locking inclined block, and at the same time, the limiting rod prevents the connecting frame from being pushed towards the moving plug by the locking inclined block. After the locking inclined block is located between the pulling plate and the moving plug, the locking inclined block moves up and down through the lower compression spring. The moving plug is pulled by the air pushing pulling spring, and the fixing plate on the air pushing half column drives the pulling plate to move towards the locking inclined block. The vertical plane of the locking inclined block cooperates with the pulling plate, and the locking inclined block pushes the pulling plate to compress the middle compression spring. The pulling plate pulls the wire, causing the inclined plane block to move down, and the limiting block disengages, separating the two combining frames; When measurement is required, flip and close the combining frame, close the combining frames at the stoma position, and the clamping ball cooperates with the clamping groove. At this time, the air pushing parts of the two combining frames correspond to each other and are on the same side. The trigger blocks on the lower sides of the two air pushing half plates abut against each other and push each other, causing the lower pulling spring to be pulled and the unlocking inclined block to be pushed. The unlocking slider drives the locking inclined block to move downward simultaneously under the action of the pressing rod. The connecting frame ensures that the pulling plate and the locking inclined block will not get stuck between the pulling plate and the fixing plate during the cooperation process. The pulling plate disengages from the locking inclined block, and the moving plug pushes the gas in the air pushing hole under the pulling of the air pushing pulling spring. The gas passes through the main air pipe, the connecting air pipe and the piston to push the moving plate to move. The bottom plate on the lower side of the moving plate fits against the edge of the lower side of the stoma to perform stoma shaping; Since the stoma extends from the body to the outside of the skin, the shape of the stoma is mostly mushroom-shaped. After trimming the stoma, it should fit as closely as possible to the lower side of the stoma to protect the skin. Through the inward structure of the bottom plate, it fits against the lower side of the stoma, and then through the pressing plate on the moving plate, the shaping is printed on the stoma bag. Through the settings of the bottom plate and the pressing plate on the moving plate, the shaping is slightly larger than the actual shape, which conforms to the operation of magnifying the measured value by 1 - 2 mm in the existing clinical operation. After the air pushing part completes the air pushing and shaping, press the control handle downward, the lower clamping frame is clamped with the combining frame, and the pressure ring tightly abuts against the piston rod of the piston to prevent the piston from continuing to move.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

When the working semi-columns (203), the working semi-plates (204), the air pushing semi-columns (312), and the air pushing semi-plates (316) on the two combined frames (1) are all on the same side, the working semi-plates (204) of the two combined frames (1) are opposite to each other, and the air pushing semi-plates (316) of the two combined frames (1) are opposite to each other.

[0024] In summary, for the stoma shaping device for stoma bag trimming of the present invention, during use, first flip the combined frame (1) on one side, and then align the combined frames (1) on both sides. At this time, the working part and the air pushing part between the two combined frames (1) are opposite, but the working part and the air pushing part between the two combined frames (1) are respectively distributed on the upper and lower sides. Combine the two combined frames (1), and the clamping ball (104) is clamped with the clamping groove (105). Through the working hole (102) on the same side, move the shifting block (2) in the working hole (102) towards the combined frame (1) on the opposite side. During the movement of the shifting block (2), after the limiting block (205) on the working half plate (204) cooperates with the inclined surface of the inclined surface block (320), the limiting block (205) cooperates with the vertical surface of the inclined surface block (320). The inclined surface block (320) moves up and down through the upper compression spring (321) to separate the two combined frames (1). The limiting block (205) pulls the inclined surface block (320), so that the moving plug (310) stores gas in the air pushing hole (101). During the pulling process, the connecting frame (3141) cooperates with the inclined surface of the locking inclined block (333), and at the same time, the limiting rod (3131) prevents the connecting frame (3141) from being pushed towards the moving plug (310) by the locking inclined block (333). After the locking inclined block (333) is located between the pulling plate (314) and the moving plug (310), the locking inclined block (333) moves up and down through the lower compression spring (331). The moving plug (310) is pulled by the air pushing pulling spring (311), and the fixing plate (313) on the air pushing half column (312) drives the pulling plate (314) to move towards the locking inclined block (333). The vertical surface of the locking inclined block (333) cooperates with the pulling plate (314), and the locking inclined block (333) pushes the pulling plate (314) to compress the middle compression spring (315). The pulling plate (314) pulls the wire (322), so that the inclined surface block (320) moves downwards, and the limiting block (205) disengages, and the two combined frames (1) are separated; When measurement is required, turn over the round frame (1), close the frame (1) at the stoma position. The ball catch (104) cooperates with the card slot (105). At this time, the air pushing parts of the two frames (1) correspond and are on the same side. The trigger blocks (319) on the lower sides of the two air pushing half plates (316) abut against each other and push each other, so as to pull the pull-down spring (317) and push the unlocking inclined block (332). Under the action of the pressure rod (330), the unlocking slider drives the locking inclined block (333) downward at the same time. The connecting frame (3141) ensures that the pulling plate (314) and the locking inclined block (333) will not get stuck between the pulling plate (314) and the fixed plate (313) during the cooperation process. The pulling plate (314) disengages from the locking inclined block (333). The moving plug (310) pushes the gas in the air pushing hole (101) under the pulling of the air pushing pull spring (311). The gas pushes the moving plate (3) through the main air pipe (110), the connecting air pipe (111) and the piston (112). The bottom plate (301) on the lower side of the moving plate (3) fits with the edge of the lower side of the stoma to perform stoma shaping; since the stoma is led out from the body to the outside of the skin, the stoma shape is mostly mushroom-shaped. After trimming the stoma, it should fit the lower side position of the stoma as much as possible to protect the skin. Through the inward structure of the bottom plate (301), it fits with the lower side of the stoma, and then through the pressing plate (302) on the moving plate (3), the shaping is printed on the ostomy bag. Through the settings of the bottom plate (301) and the pressing plate (302) on the moving plate (3), the shaping is slightly larger than the actual shape, which conforms to the operation of magnifying the measured value by 1-2 mm in the existing clinical operation. After the air pushing part completes the air pushing and shaping, press down the control handle (303), the lower card frame is clamped with the frame (1), and the pressure ring (306) tightly abuts against the piston rod of the piston (112) to prevent the piston (112) from continuing to move.
