Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to an ostomy bag base plate incision device. Background Technology

[0002] For patients whose normal bowel function cannot be completed through the anus due to certain diseases (such as colorectal cancer, intestinal obstruction) or surgery, it is necessary to excrete feces through an abdominal stoma (artificial anus), and the ostomy bag is an essential medical device for collecting and managing excrement.

[0003] The commonly used two-piece ostomy bag consists of a bag for collecting stoma excrement and a base plate detachably connected to the bag. The base plate includes a soft plate body, a circular mounting ring protruding from one end of the soft plate body, and a release paper with a stoma ruler (consisting of multiple concentric circles) located at the other end of the soft plate body. Traditionally, medical staff use scissors to cut stoma holes of different sizes, based on the diameter of the circles on the stoma ruler, to accommodate different sized artificial anuses. However, this method makes it difficult to create regular, smooth, and neat incisions; rough stoma holes can easily scratch the skin, and repeated trimming is time-consuming. Utility Model Content

[0004] In view of the technical problems existing in the prior art, this utility model provides an ostomy bag base plate incision device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ostomy bag base plate incision device is disclosed for cutting an ostomy bag base plate. The base plate includes a soft plate body, an annular mounting ring protruding from one end of the soft plate body, and a release paper with an ostomy ruler at the other end of the soft plate body. The soft plate body has a circular hole coaxial with the mounting ring. The ostomy bag base plate incision device includes a base with a mounting cavity, a rotating platform installed in the mounting cavity, an electric drive mechanism connected to the rotating platform for driving the rotating platform to rotate horizontally, a positioning mechanism on the rotating platform for fixing the base plate, a lifting bracket on one side of the base, a support rod vertically connected to one side of the lifting bracket, and a cutter vertically connected to the support rod. The positioning mechanism includes a cutting cavity capable of accommodating the ostomy ruler. The cutter can enter / exit the cutting cavity, and the cutter entering the cutting cavity can abut against the ostomy ruler. The cutter's position can be adjusted radially within the cutting cavity.

[0007] Furthermore, a magnetic block is embedded on the top surface of the rotating platform, and the magnetic block attracts a frustum that can be accommodated within the mounting ring.

[0008] Furthermore, the positioning mechanism also includes an annular pressing member whose inner cavity is defined as a cut-in-the-inner cavity, a tail fin fixed to the outer wall of the annular pressing member, two lugs fixed to the end face of the tail fin near the rotating platform and arranged at intervals, two support arms inclinedly arranged on the top surface of the rotating platform and arranged at intervals, a hinge shaft connecting the support arms and the lugs, and a torsion spring sleeved on the hinge shaft. The torsion spring is located between the two lugs. Pressing the tail fin allows the annular pressing member to reciprocate in a direction toward or away from the rotating platform.

[0009] Furthermore, the bottom surface of the annular clamping member is covered with a silicone layer.

[0010] Furthermore, the annular clamping member is provided with a plurality of threaded holes arranged at intervals around the center, and each threaded hole is threaded with a clamping screw, the end of the clamping screw near the rotating table being covered with a silicone layer.

[0011] Furthermore, the support rod includes a main rod body with one end screwed to the lifting bracket, and a limiting block screwed to the main rod body; the cutter includes a movable sleeve through which the main rod body can pass, a fastening bolt screwed to the movable sleeve and capable of locking the position of the movable sleeve, and a blade body connected to the outside of the movable sleeve, the movable sleeve being capable of reciprocating along the length direction of the main rod body.

[0012] Furthermore, a screw cylinder is fixedly connected to the outer wall of the base, and the bottom end of the lifting bracket is screwed to the screw cylinder.

[0013] Furthermore, the base has a storage cavity located below the mounting cavity, and a storage drawer capable of entering / exiting the storage cavity is installed in the storage cavity.

[0014] Furthermore, the electric drive mechanism includes a housing disposed within the mounting cavity and located below the rotary table, a drive motor installed within the housing, a first bevel gear connected to the drive motor, a second bevel gear meshing with the first bevel gear, and a support shaft connected to the second bevel gear, the top end of the support shaft being detachably connected to the rotary table.

[0015] In summary, the beneficial effects of this utility model are as follows: 1. The drive motor drives the rotary table to rotate smoothly through a bevel gear transmission system (first bevel gear plus second bevel gear), while the cutter position is fixed, achieving a "chassis moving, cutter stationary" cutting mode. Compared with the traditional manual rotation or movement of the cutter, the roundness error and edge roughness of the cut are smaller, making it easier to quickly cut smooth and flat incisions, effectively avoiding rough edges irritating the skin around the stoma. Automated operation does not rely on the experience of medical personnel, reducing human error. 2. The same device, through the "rotary frustum / silicone pad switching" on the rotary table, is not only specifically used for cutting convex (with mounting ring) chassis, but can also be used for cutting flat chassis, saving costs and resources. 3. The tail wing plus torsion spring structure enables the ring-shaped holding part to be pressed and fixed with one hand, making it convenient to pick up and put down the chassis. The height and horizontal position of the cutter are adjustable to adapt to different cutting needs. 4. The bottom end of the lifting bracket is screwed to the base screw cylinder, and the support rod is screwed to the lifting bracket, both of which can be quickly disassembled. After disassembly, the support rod and lifting bracket can be stored in the hidden storage drawer under the base, changing the equipment from a "three-dimensional assembly state" to a "flat stacked state". This reduces the size and makes it easy to store in a treatment cabinet or carry to the bedside, making it especially suitable for small-space primary medical institutions or home care scenarios.

Detailed Implementation

[0020] The present invention will be further illustrated below with reference to specific figures.

[0021] Please see Figure 1This utility model provides an ostomy bag base plate cutting device for cutting ostomy bag base plates. The base plate includes a soft plate body, an annular mounting ring protruding from one end of the soft plate body, and a release paper with an ostomy ruler at the other end of the soft plate body. The soft plate body is provided with a circular hole coaxial with the mounting ring. The ostomy bag base plate incision device includes a base 100 having a mounting cavity 110, a rotary table 200 mounted in the mounting cavity 110, an electric drive mechanism 300 connected to the rotary table 200 for driving the rotary table 200 to rotate horizontally, a positioning mechanism 400 disposed on the rotary table 200 for fixing the base plate, a lifting bracket 500 disposed on one side of the base 100, a support rod 600 vertically connected to one side of the lifting bracket 500, and a cutter 700 vertically connected to the support rod 600. The positioning mechanism 400 includes a cutting cavity capable of accommodating the stoma ruler. The cutter 700 can enter / exit the cutting cavity, and the cutter 700 entering the cutting cavity can abut against the stoma ruler. The cutter 700 can be radially adjusted in position within the cutting cavity. The base is fixed using the positioning mechanism 400, aligning the stoma ruler with the cutter 700. The electric drive mechanism 300 is then activated, rotating the rotary table 200. The cutter 700 cuts a smooth stoma with even edges on the stoma ruler. This device uses the electric drive mechanism 300 to drive the rotary table 200 to rotate horizontally, working in conjunction with the radially adjustable cutter 700 to achieve uniform circular motion cutting. This ensures a standard circular cut with smooth, even edges, preventing rough edges from scratching the skin around the stoma and reducing the risk of infection. This device employs automated rotary cutting with a standardized operating procedure, requiring no personal skill. Even beginners can quickly complete high-quality incisions, reducing human error. A single cut achieves the desired shape, eliminating the need for multiple adjustments and trimmings, shortening operation time, and reducing the risk of base material damage due to repeated cutting, thus minimizing material waste.

[0022] The base 100 has a storage cavity 120 located below the mounting cavity 110, and a storage drawer 121 that can enter and exit the storage cavity 120 is installed in the storage cavity 120. The lower storage cavity 120 is embedded inside the base 100, and the drawer structure hides the storage accessories, improving space utilization.

[0023] A screw-in cylinder (not shown in the figure) is fixedly connected to the outer wall of the base 100, and the bottom end of the lifting bracket 500 is screwed to the screw-in cylinder. The lifting bracket 500 is telescopically adjustable in height, allowing the distance between the cutter 700 and the ostomy ruler to be flexibly adjusted. The lifting bracket 500 can be separated from the base 100 and can be easily placed in the storage drawer 121 when retracted, which saves storage space.

[0024] Please see Figure 2The positioning mechanism 400 also includes an annular pressing member 410 whose inner cavity is defined as a cut-in-the-inner cavity, a tail fin 420 fixed to the outer wall of the annular pressing member 410, two lugs fixed to the end face of the tail fin 420 near the rotary table 200 and arranged at intervals, two support arms 430 inclinedly arranged on the top surface of the rotary table 200 and arranged at intervals, a hinge shaft 440 connecting the support arms 430 and the lugs, and a torsion spring 450 sleeved on the hinge shaft 440. The torsion spring 450 is located between the two lugs. Pressing the annular pressing member 410 of the tail fin 420 can reciprocate in the direction of approaching or moving away from the rotary table 200. When the annular pressing member 410 moves towards the rotary table 200, it can press the soft disc body, and conversely, it can open the annular pressing member 410 and release the pressure on the chassis. The inner cavity of the annular clamping member 410 is a cutting cavity, the shape of which is usually matched with the mounting ring of the stoma base plate. After clamping the soft plate body and accommodating the mounting ring in the cutting cavity, the annular clamping member 410 can apply uniform pressure along the edge of the base plate to avoid local deformation caused by single-point fixation.

[0025] The bottom surface of the annular support member 410 is covered with a silicone layer, which elastically compensates for unevenness on the surface of the soft disc. Some stoma base plates may have slight curvature at the edges or unevenness caused by the manufacturing process (such as slight lifting of the adhesive layer edge). The elasticity of the silicone layer can adaptively conform to the irregular surface, filling gaps through local compression and ensuring uniform force distribution throughout the annular area. In addition, it can also increase the friction of the contact surface and prevent the base plate from sliding.

[0026] The annular clamping member 410 has several threaded holes arranged at intervals around the center. Each threaded hole is threaded with a clamping screw 411, and the end of the clamping screw 411 near the rotating table 200 is covered with a silicone layer. When it is not necessary to pressurize and fix the soft disk, rotating the clamping screw 411 can move the clamping end of the clamping screw 411 away from the soft disk. If it is necessary to reinforce the soft disk in addition to the clamping of the annular clamping member 410, rotating the clamping screw 411 can extend the clamping end of the clamping screw 411 from the threaded hole to clamp the soft disk. In addition, in order to protect the soft disk, the clamping end of the clamping screw 411 is also covered with a silicone layer.

[0027] A magnetic block 210 is embedded on the top surface of the rotating stage 200. The magnetic block 210 attracts a frustum 230 that can be accommodated in the mounting ring. This frustum 230 can support the ostomy ruler below. The soft disk of the convex base (or the base with the mounting ring) itself has a certain curvature or rigid structure. If there is no support below during cutting, the pressure during cutting may cause the soft disk to dent or shift locally. The frustum 230 is accommodated in the mounting ring and supports the ostomy ruler below, which is equivalent to providing a rigid support base inside the base, keeping the concentric circle scale of the ostomy ruler flat, avoiding the reference deformation caused by uneven force, and thus ensuring that the size of the cut is consistent with the markings on the ostomy ruler. The magnetic block 210 has a silicone pad 220 on its top surface that is flush with the rotary table 200. When cutting the flat base, the frustum 230 can be removed and placed on the silicone pad 220. The flat base has a flat adhesive surface without a mounting ring or convex structure. If the frustum 230 is used directly for support, the base may be suspended because the top surface of the frustum 230 is higher than the rotary table 200 (when not removed), making it easy to slip during cutting. After removing the frustum 230, the silicone pad 220 on the top surface of the magnetic block 210 is flush with the rotary table 200, forming a flat support surface that matches the flatness of the flat base, ensuring that the base fits the support surface completely during cutting and preventing wobbling. The silicone material has high friction, which can fix the position of the flat base and prevent the base from shifting as the cutter 700 moves during cutting.

[0028] The support rod 600 includes a main rod body 610 that is screwed to the lifting bracket 500 at one end, and a limiting block 620 that is screwed to the main rod body 610. The support rod 600 can be detached from the lifting bracket 500, and the detached support rod 600 can also be stored in the storage drawer 121, saving more space during storage.

[0029] The cutter 700 includes a movable sleeve 710 through which the main shaft 610 passes, a fastening bolt 720 screwed to the movable sleeve 710 and capable of locking the position of the movable sleeve 710, and a blade body 730 connected to the outside of the movable sleeve 710. The movable sleeve 710 can reciprocate along the length of the main shaft 610. Before cutting, the movable sleeve 710 is locked to the main shaft 610 by the fastening bolt 720, forming a rigid connection structure to prevent stress on the blade during cutting. The blade body 730 can be adjusted in position within the cutting cavity. Through dual adjustment of height and horizontal position, different sizes of chassis cuts can be flexibly cut.

[0030] Please see Figure 3The electric drive mechanism 300 includes a housing 310 disposed within the mounting cavity 110 and located below the rotary table 200, a drive motor 320 mounted within the housing 310, a first bevel gear 330 connected to the drive motor 320, a second bevel gear 340 meshing with the first bevel gear 330, and a support shaft 350 connected to the second bevel gear 340. The rotary table 200 is actively rotated via the drive motor 320 and the bevel gear transmission system (first bevel gear 330 and second bevel gear 340), replacing manual operation and improving cutting efficiency and stability. The motor can precisely control the rotation speed and angle, ensuring a more uniform concentric circle reference for the stoma base incision, making it particularly suitable for complex shapes or high-precision requirements (such as differentiated cutting of convex / flat bases). When the motor drives the rotary table 200 to rotate, the cutting pen position is fixed, and the base rotates with the rotary table 200 to complete the cutting, reducing human error and making it particularly suitable for one-time forming of concentric or arc-shaped incisions. The top of the support shaft 350 is screwed to the rotary table 200. If the electric drive mechanism 300 fails, the screwed rotary table 200 can be easily and quickly disassembled.

[0031] This incision device features: 1. A drive motor 320, via a bevel gear transmission system (first bevel gear 330 plus second bevel gear 340), smoothly rotates the rotary table 200 while the cutter 700 remains stationary, achieving a "rotating chassis, stationary cutter" cutting mode. Compared to traditional manual rotation or movement of the cutter, this method results in less roundness error and less edge roughness, facilitating the quick and easy creation of smooth, flat incisions and effectively preventing rough edges from irritating the skin around the stoma. Automated operation eliminates the need for experienced medical personnel, reducing human error. 2. The same device, through the "rotary table 230 / silicone pad 220 switching" on the rotary table 200, can be used not only for cutting convex (with mounting ring) chassis but also for cutting flat chassis, saving costs and resources. 3. A tail wing 420 with a torsion spring 450 structure allows for one-handed pressing and fixing of the annular holding member 410, facilitating chassis removal and placement. The height and horizontal position of the cutter 700 are adjustable to adapt to different cutting needs. IV. The bottom of the lifting bracket 500 is screwed to the base 100 screw sleeve, and the support rod 600 is screwed to the lifting bracket 500, both of which can be quickly disassembled. After disassembly, the support rod 600 and the lifting bracket 500 can be stored in the hidden storage drawer 121 under the base 100, changing the equipment from a "three-dimensional assembly state" to a "flat stacked state", reducing its size and making it easy to store in a treatment cabinet or carry to the bedside, especially suitable for space-constrained primary medical institutions or home care scenarios.
