Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a ureteral stent tube fixing device. Background Art

[0002] With the increasing aging of society and the current situation of increasing tumor incidence, the probability of elderly male patients suffering from bladder cancer is also increasing. At present, the main method of radical cystectomy combined with urinary diversion is to treat muscle-invasive and high-risk non-muscle-invasive bladder cancer; in addition, some patients are treated by combining bladder placement with urinary diversion. Among them, in urinary diversion treatment, ureterocutaneous ureterostomy has the best specific survival rate and is often used for patients with weaker constitutions.

[0003] Specifically, when performing ureterostomy, the ureteral stent is first inserted into the tail end of the ureter through the skin stoma, thereby fixing it in the renal pelvis; then, the leaking part of the ureteral stent is placed in a disposable stoma bag, and urine is drained after it is fixed. However, from the perspective of long-term clinical use, although the ureteral stent is fixed with a stoma bag, it is very easy to fall out due to the patient's daily activities and the peristalsis of the ureter itself, which brings great trouble to the patient and is not conducive to the patient's recovery. Utility Model Content

[0004] In view of the above problems, an embodiment of the utility model provides a ureteral stent tube fixing device to solve the problem that the ureteral stent tube is difficult to fix.

[0005] The utility model provides a ureteral stent tube fixing device, comprising:

[0006] The clamping body has a deformation part and side wings connected to two sides of the deformation part, and the side wings are provided with limiting grooves matched with the ureteral stent tube;

[0007] Support plates are symmetrically arranged on both sides of the bottom of the side wings;

[0008] The handle is connected to the side wing. In response to external force, when the clamping body switches between the clamping position and the open position, the support plates are brought closer or separated so that the side wing and the deformation part are surrounded to form an installation space for the ureteral stent tube to pass through.

[0009] In some embodiments, the cross-section of the limiting groove is arc-shaped, and the radius of the limiting groove is not less than the radius of the ureteral stent tube.

[0010] In some embodiments, the arc length of the limiting groove is between 1 / 4 and 1 / 2 of the circumference of the ureteral stent tube.

[0011] In some embodiments, the cross section of the clamping body is in an inverted U shape, and the clamping body is made of an elastic material.

[0012] In some embodiments, a cross section of the deformation portion is arc-shaped, and an opening of the deformation portion faces the installation space.

[0013] In some embodiments, an angle is formed between the support plate and the side wing, and the angle ranges from 60° to 130°.

[0014] In some embodiments, the deformation portion and the side wings are integrally formed.

[0015] In some embodiments, the support plate includes a flexible plate body and a memory alloy disposed inside the flexible plate body.

[0016] In some embodiments, the memory alloy is one of a nickel-titanium alloy, a copper-nickel alloy, a copper-aluminum alloy, a copper-zinc alloy and an iron alloy.

[0017] In some embodiments, an anti-slip member is disposed at the bottom of the flexible board.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are as follows:

[0019] The ureteral stent tube fixing device provided by the utility model comprises a clamping body, a support plate and a handle. The clamping body has a deformation part and a wing, and the handle is connected to the wing. The user can transmit the external force to the wing by operating the handle. Since the wing is connected to the deformation part, the deformation part can be deformed under the action of the external force and the support plate is separated. At this time, the ureteral stent tube can pass through the installation space and cooperate with the limiting groove, so as to realize the limiting fixation of the ureteral stent tube by the fixing device. This type of fixing device has a simple overall structure and a simple operation method. The user can even operate it with one hand, which is beneficial to the user experience. In addition, through the cooperation between the limiting groove and the ureteral stent tube, a good limiting fixation of the ureteral stent tube can be realized, so that the ureteral stent tube can be prevented from being separated from the ureter due to the patient's activities or the peristalsis of the ureter to a large extent, thereby facilitating the treatment and rehabilitation of the patient. In addition, the support plates arranged on both sides of the wing increase the contact area between the fixing device and the user's appearance, thereby facilitating the improvement of the clamping stability of the fixing device.

[0030] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein.

[0031] Reference Figure 1-Figure 3 As shown, the utility model provides a ureteral stent tube fixing device, including a clamping body 100, a supporting plate 200 and a handle 300. The clamping body 100 has a deformation portion 110 and side wings 120 connected to both sides of the deformation portion 110, and the side wings 120 are provided with limiting grooves 121 that match the ureteral stent tube; the supporting plates 200 are symmetrically arranged on both sides of the bottom of the side wings 120, and the handle 300 is connected to the side wings 120; and in response to the external force, the clamping body 100 is switched between the clamping position and the open position, and the supporting plates 200 are close to or separated, so that the side wings 120 and the deformation portion 110 are enclosed to form an installation space (not marked in the figure) for the ureteral stent tube to pass through.

[0032] It should be noted that the clamping body 100 in the present application, as the core component of the fixing device, mainly realizes the position fixing of the ureteral stent by switching between the clamping position and the open position. Therefore, the deformation path of the deformation part 110 in the clamping body 100 is adapted to the shape of the clamping position and the open position. Exemplarily, the deformation part 110 can be an elastic connecting plate. When in the clamping position, the deformation part 110 is in a natural extension state, and one end of the side wing 120 connected to the two sides of the deformation part 110 is close to each other; when in the open position, the deformation part 110 is in an elastic deformation state driven by the side wing 120, and one end of the side wing 120 is far away from each other; in addition, the deformation part 110 can also include a rigid plate and a compression spring, the two ends of the rigid plate are respectively connected to the side wing 120 for rotation, and the compression spring is respectively connected to the inner wall of the rigid plate and the side wing 120; when in the clamping position, the compression spring is in a compressed state, and the side wing 120 is brought closer to the middle of the rigid plate, and the installation space has a tendency to be closed; when in the open position, the compression spring is in a stretched state, and the side wing 120 moves to both sides of the rigid plate, so that the installation space has a tendency to be opened. It can be found that there are many different implementations of the specific structure of the deformation part 110, and this application does not limit this.

[0033] In addition, the handle 300 connected to the side wing 120, as a force-bearing structure, can be implemented in different ways to facilitate the user's operation and grip, and to expand the user's operation methods:

[0034] Embodiment 1: The handle 300 can be fixedly connected to the bottom end of the side wing 120, and the user can press the handles 300 on both sides of the clamping body 100 with one hand at the same time to deform the deformation part 110, thereby realizing the switching of the clamping body 100 between the clamping position and the open position. Preferably, in this implementation form,

[0035] Embodiment 2: The handle 300 can be rotatably connected to the bottom end of the side wing 120. When the user presses the handle 300 on both sides of the clamping body 100 with one hand at the same time, the handle 300 rotates relative to the side wing 120, and the middle and upper area of ​​the handle 300 body can press against the connection between the side wing 120 and the deformation part 110, so that the fixing device forms a lever structure as a whole, thereby deforming the deformation part 110 and realizing the switching of the clamping body 100 between the clamping position and the open position.

[0036] Embodiment 3: The handle 300 can be fixedly connected to the outer wall of the side wing 120, and the handle 300 extends toward the outside of the side wing 120. In this real-time mode, the user holds the handles 300 on both sides with both hands, so that the side wings 120 are separated and the deformation part 110 is deformed, thereby realizing the switching of the clamping body 100 between the clamping position and the open position.

[0037] On the other hand, the handle 300 is used as a force-applying structure. In order to make the user's operation more labor-saving and more effectively transmit the external force to the deformation part 110, the handle 300 can be formed into a labor-saving structure by changing the size of the handle 300. For example, in the above-mentioned embodiments 1 to 3, the length of the handle 300 can be set to be 3-5 cm longer than the length of the side wing 120, so as to appropriately increase the length of the handle 300 so that the handle 300 has a longer force arm.

[0038] In addition, the support plate 200 is symmetrically arranged on both sides of the bottom of the side wing 120, and can directly contact the human body surface. Therefore, in order to improve the fit between the support plate 200 and the human body surface, preferably, the support plate 200 can be set as an arc plate, and the arc plate is adapted to the contour of the human body surface, so as to achieve a close fit between the support plate 200 and the human body surface, and further improve the stability of the fixing device.

[0039] In other embodiments, the support plate 200 may further include a flexible plate body (not marked in the figure) and a memory alloy (not shown in the figure) arranged inside the flexible plate body, wherein the memory alloy is one of a nickel-titanium alloy, a copper-nickel alloy, a copper-aluminum alloy, a copper-zinc alloy and an iron alloy.

[0040] Through the flexibility of the flexible board itself (the flexibility can be formed by the elasticity of the materials such as silicone and rubber used in the flexible board), the support board 200 has the ability to deform to a certain extent, and the shape of the support board 200 after deformation is adapted to the contour of the human body. In addition, the memory alloy arranged inside the flexible board can keep the flexible board in a fixed position after deformation, which is conducive to maintaining the stability of the fixing device.

[0041] The ureteral stent tube fixing device provided by the utility model can transmit external force to the wing 120 by operating the handle 300. Since the wing 120 is connected to the deformation part 110, the deformation part 110 can be deformed under the action of external force, and the support plate 200 is separated. At this time, the ureteral stent tube can pass through the installation space and cooperate with the limiting groove 121, so as to realize the limiting fixation of the ureteral stent tube by the fixing device. This type of fixing device has a simple overall structure and a simple operation method. The user can even operate it with one hand, which is beneficial to the user experience. In addition, through the cooperation between the limiting groove 121 and the ureteral stent tube, a good limiting fixation of the ureteral stent tube can be achieved, so that the ureteral stent tube can be prevented from being separated from the ureter due to the patient's activity or the peristalsis of the ureter to a large extent, thereby facilitating the treatment and rehabilitation of the patient. In addition, the support plates 200 arranged on both sides of the wing 120 increase the contact area between the fixing device and the user's appearance, thereby facilitating the improvement of the clamping stability of the fixing device.

[0042] In some embodiments, the cross-section of the limiting groove 121 is arc-shaped, and the radius of the limiting groove 121 is not less than the radius of the ureteral stent tube.

[0043] Generally speaking, the cross section of the ureteral stent tube is mostly circular. By setting the cross section of the limiting groove 121 to an arc shape, the limiting groove 121 can be better adapted to the shape of the ureteral stent tube, thereby improving the matching accuracy of the limiting groove 121 and the ureteral stent tube. However, it should be noted that the limiting groove 121 can be not only a circular groove, but also an elliptical groove. The specific structure of the limiting groove 121 is not limited in this application. In addition, the present application limits the size of the limiting groove 121, such as making the radius of the limiting groove 121 greater than or equal to the radius of the ureteral stent tube, so that there is a gap or just fit between the limiting groove 121 and the ureteral stent tube; when there is a gap between the two, it is conducive to the assembly of the limiting groove 121 and the ureteral stent tube. When the two are just fit, the limiting groove 121 can stably limit the ureteral stent tube inside the limiting groove 121, and prevent the ureteral stent tube from shaking in the limiting groove 121 as much as possible. The present application also does not limit the size of the limiting groove 121.

[0044] Preferably, the arc length of the limiting groove 121 is between 1 / 4 and 1 / 2 of the circumference of the ureteral stent. The present application further limits the arc length of the limiting groove 121, so that the limiting groove 121 can meet the convenience of assembling the ureteral stent while also taking into account the stability of the ureteral stent in the limiting groove 121.

[0045] In some embodiments, the cross section of the clamping body 100 is inverted U-shaped, and the clamping body 100 is made of an elastic material, wherein the elastic material may be elastic metal, rubber, silicone, etc.

[0046] The cross section of the clamping body 100 is set to an inverted U shape, which can make the clamping body 100 itself have a certain elasticity from the structural point of view, so that the clamping body 100 can switch between the clamping position and the closed position. In addition, in the clamping body 100 made of elastic material, not only the deformation part 110 can be made of elastic material, but also the side wing 120 can be made of elastic material. This method can further improve the elastic deformation ability of the clamping body 100 from the material level, so that the clamping body 100 has a larger opening and closing angle in the clamping position, and then the installation space can be used for a larger size of ureteral stent tube to pass through, that is, the clamping body 100 can adapt to ureteral stent tubes of various diameters.

[0047] In a specific example, the cross section of the deformable portion 110 is arc-shaped, and the opening of the deformable portion 110 faces the installation space. By setting the cross section of the deformable portion 110 to be arc-shaped, the elastic deformation capability of the deformable portion 110 can be further improved.

[0048] Furthermore, there is an angle between the support plate 200 and the side wing 120, and the angle ranges from 60° to 130°. The large angle between the support plate 200 and the side wing 120 can make the support plate 200 tilt downward to a certain extent, so that the support plate 200 can clamp the human body surface to a certain extent, thereby facilitating the fixation of the support plate 200 on the human body surface and improving the stability of the fixing device.

[0049] Preferably, the deformable portion 110 and the side wing 120 are integrally formed, which helps to ensure the overall structural strength of the clamping body 100. In addition, the integrally formed method does not require the user to assemble the components in the fixing device, thereby facilitating the use of the user.

[0050] In some embodiments, reference Figure 4 As shown, when the support plate 200 adopts a setting mode combining a flexible plate body and a memory alloy, an anti-skid member 210 may be further provided at the bottom of the flexible plate body. The anti-skid member 210 may be an anti-skid rib, an anti-skid pad, an anti-skid protrusion, etc. The material of the anti-skid member 210 may be skin-friendly silicone, latex, etc., and the present application does not limit the structure and material of the anti-skid member 210.
