Description

Technical Field

[0001] The present invention relates to the technical field of cutting devices, and particularly to a cutting auxiliary device for a stoma bag. Background Art

[0002] In medical treatment, for patients with rectal or bladder lesions, in order to save the patient's life, the diseased part will be removed, leaving a stoma on the body surface. A stoma bag will be placed on the surface of the stoma. The stoma bag is a device to help patients collect excreta. When making the stoma bag, it needs to be cut. Each stoma has a different size and shape, and the stoma of the required stoma bag is also different. The stoma of stoma patients is not a regular perfect circle. Therefore, it is difficult to cut the opening of the stoma bag into a size that matches the stoma size.

[0003] In the prior art, the method of tracing the shape of the stoma with a transparent plastic paper and then covering it on the chassis to outline and cut is often used. However, due to the mistakes of the operator, situations such as the cut shape being exactly the opposite of the actual shape from left to right, or the pasting angle of the stoma bag being incorrect, resulting in the cut hole not matching the stoma, will occur. There will also be problems of the stoma being too large or too small, leading to waste of the stoma bag. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a cutting auxiliary device for a stoma bag to solve the problems raised in the above background art. The structure of the present invention is novel. The stoma bag is clamped between the bottom plate and the clamping plate. Through the measurement component, multiple points of the patient's stoma are selected. The trajectory of the guiding component is adjusted to be similar to the stoma. The cutting component cuts the stoma bag along the path of the guiding component, improving the accuracy of the cutting shape and avoiding the problem that the opening of the stoma bag is too large or too small compared with the patient's stoma.

[0006] Further, at the middle position of one end of the bottom plate, there is a connecting column rotatably installed through a rotating shaft, and the bottom of the connecting column is fixedly connected to one end of the fixed sliding frame.

[0007] Further, the measuring component further includes a screw rod. Inside both the fixed sliding frame and the rotating sliding frame, there are two screw rods rotatably installed through bearings. The two sliders are respectively threadedly sleeved on the surfaces of the corresponding screw rods.

[0008] Further, at the bottom of the slider, there is a cone, and the bottommost parts of the cones of the rotating sliding frame and the fixed sliding frame are on the same plane.

[0009] Further, the guiding component further includes a connecting frame. On the outer side of the outer rubber ring, there is a connecting frame fixedly connected, and the bottom of the connecting frame is fixedly connected to the vertical rod. The number and position of the connecting frames correspond to those of the vertical rods.

[0010] Further, the cutting component further includes a rotating rod. At the top of the central shaft, there is a rotating rod rotatably installed through a bearing, and the top of the rotating rod contacts the inner hole of the cutting surface of the stoma bag body. On the surface of the rotating rod, there is a connecting plate, and the cutting knife passes through the inside of the connecting plate.

[0011] Further, at the topmost part of the rotating rod, there is a first limiting plate, and the first limiting plate penetrates into the stoma bag body.

At one end of the second limiting plate close to the rotating rod, there is a collar, and the collar is slidably sleeved on the surface of the rotating rod.

[0012] Furthermore, a return spring is rotatably mounted on the top of the collar through a shaft ring, and the top of the return spring is fixedly connected to the first limit plate.

[0013] Furthermore, the second limiting plate and the connecting plate are provided with the same sliding groove on their surfaces, and a moving block is slidably connected inside the sliding groove, and a slot is provided inside the moving block, and the cutting knife slides through the slots of the two moving blocks.

[0015] Beneficial effects of the present invention:

[0016] 1. When the measuring component of the present invention is adjusted according to the shape of the patient's stoma, the cutting knife will move with the guiding component, clamp the stoma bag body between the bottom plate and the clamping plate, and use scissors to cut from the circular hole in the middle of the stoma bag to the position of the top of the cutting knife to facilitate the insertion of the cutting knife, and then insert the first limit plate from the circular hole of the stoma bag body to contact the inner surface of the stoma bag body, then release the reset spring, the second limit plate contacts the outer surface of the stoma bag body, and the cutting knife penetrates the cutting opening, and the handle is manually controlled to move along the path of the guiding component. Through the connection between the connecting plate and the vertical rod, the shaft rod will rotate with the cutting knife, the first limit plate and the second limit plate rotate synchronously, and maintain the squeezing effect on the inner and outer sides of the cutting position of the stoma bag on the cutting path of the cutting knife to prevent the problem of cutting obstruction or mismatch of cutting size caused by wrinkles in the stoma bag.

[0017] 2. The present invention uses the sliding grooves of the second limit plate and the connecting plate and the moving block to connect with the cutting knife, and the cutting knife can maintain connectivity with the connecting plate and the second limit plate by sliding the moving block along the sliding groove according to the sleeve position of the guide assembly. The cutting knife is slidably engaged with the outer rubber ring and the inner rubber ring through the protrusions at the top and bottom of the plug block to prevent the plug block from being separated from the gap of the rubber ring.

[0018] 3. The present invention fixes the bottom of the vertical rod on the slider, and the fixed sliding frame and the rotating sliding frame select the irregular points on the patient's stoma, and the cone is matched with the two ends of the irregular points of the stoma. The vertical rod moves synchronously. Due to the retractability of the outer rubber ring and the inner rubber ring, they will be synchronized to a shape similar to the stoma, and the gap between the inner rubber ring and the outer rubber ring can be used for the movement of the insert block of the cutting knife to guide the cutting knife when cutting.

[0019] 4. In the present invention, the fixed sliding frame is used as the basic point position and is rotatably connected to the bottom plate through the connecting column. When shaping the stoma of the patient, the bottom plate is turned over and opened, which facilitates manual adjustment of the positions of the fixed sliding frame and the rotating sliding frame according to the size and shape of the stoma. There are two point positions inside both the fixed sliding frame and the rotating sliding frame, which can be adjusted separately. Moreover, these two point positions are on the straight line corresponding to the center of the stoma. According to the shape of the patient's stoma, multiple straight lines are selected, and each rotating sliding frame is rotated to the selected straight line. Then, the screw is rotated, and the slider moves inside the fixed sliding frame and the rotating sliding frame until the bottom of the cone corresponds to the two ends of the straight line of the stoma. By selecting multiple groups of point positions, the guiding component can roughly simulate the shape of the stoma and provide a path for the movement of the cutting knife. The fixed sliding frame and the rotating sliding frame are arranged in a vertically offset manner, which facilitates rotation and separation. And the bottoms of the two cones at the bottom of each sliding frame are on the same plane, which is convenient for adjustment according to the stoma position of the patient. The bottom of the cone does not need to contact the human skin, or a protective sleeve is provided at the bottom of the cone to avoid damaging the human skin. The bottoms of the cones are arranged at multiple point positions on the periphery of the stoma to simulate the shape of the stoma. After the guiding component is adjusted, the bottom plate is turned to the top to clamp and cut the ostomy bag body.

[0020] 5. Compared with the prior art, in the present invention, the ostomy bag is clamped between the bottom plate and the clamping plate. The measurement component makes multi-point selection of the patient's stoma, adjusts the trajectory of the guiding component to be similar to the stoma, and uses the cutting component to cut the ostomy bag along the path of the guiding component, improving the accuracy of the cutting shape and avoiding the problem that the opening of the ostomy bag is too large or too small compared with the patient's stoma.
