Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an artificial contraction structure and a medical device. Background Art

[0002] In the medical field, artificial contractile structures are widely used to treat diseases such as urinary incontinence due to their adjustability and adaptability. Artificial contractile structures can effectively treat diseases by reducing the diameter of organs or achieving occlusion of organs by applying pressure. In particular, in the treatment of urinary incontinence, such artificial contractile structures essentially form an artificial sphincter, which can open and close the urethra by controlling the applied pressure.

[0003] In the prior art, the contraction band of an artificial contractile structure is usually fixed by buckling a closure member and a reinforcing element. The reinforcing elements are arranged at equal intervals on the contraction band to ensure that the contraction band can be evenly stressed when pressure is applied, avoiding excessive local pressure and damage to the organ. However, this fixing method relies on the buckling of multiple discrete reinforcing elements with the closure member. Since the reinforcing elements are arranged at equal intervals, it is difficult to adapt to organs of different sizes and shapes, resulting in poor versatility. Utility Model Content

[0004] The problem solved by the utility model is that in the prior art, the reinforcing elements are arranged at equal intervals, which makes it difficult to adapt to organs of different sizes and shapes, resulting in poor versatility.

[0005] In order to solve the above problems, the utility model provides an artificial contraction structure, which includes: a contraction band, a fixing seat is provided at one end of the contraction band, and a clamping portion is provided at the other end, and the fixing seat cooperates with the clamping portion so that the contraction band surrounds the target object; the fixing seat includes a fixing piece, and the clamping portion is provided with an oblique tooth groove; when the fixing seat cooperates with the clamping portion, the fixing piece abuts against the inclined surface of the oblique tooth groove to limit the clamping portion from moving in a direction away from the fixing seat.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the contraction band can wrap around the target object through the cooperation between the fixing seat at one end of the contraction band and the clamping part at the other end. This design enables the contraction band to flexibly adapt to organs of different sizes and shapes, thereby improving its versatility and adaptability. Specifically, when the target object is a human organ, such as the urethra, and the contraction band wraps around the human organ, the clamping part cooperates with the fixing seat. At this time, the fixing piece on the fixing seat abuts against the inclined surface of the oblique tooth groove on the clamping part, so that the contraction band can be tightened to a diameter that fits the target object, and the contraction band will not detach from the fixing seat. The contraction band can adapt to organs of different sizes and shapes through the cooperation between the fixing piece and the inclined surface of the oblique tooth groove.

[0007] Furthermore, the fixing seat is provided with a rotating shaft and an elastic member, and the fixing member is rotatably connected to the fixing seat via the rotating shaft; the elastic member is sleeved on the rotating shaft to drive the fixing member to lean against the inclined surface.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by arranging an elastic member between the fixing seat and the fixing member, the fixing member drives the fixing member to lean against the inclined surface, thereby ensuring a stable connection between the clamping portion and the fixing seat.

[0009] Furthermore, the fixing member includes a buckle portion and a pressing portion connected to each other, and the buckle portion is in contact with the inclined surface; wherein, when pressure is applied to the pressing portion, the buckle portion rotates in a direction away from the oblique tooth groove to release the cooperation between the fixing seat and the clamping portion.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the buckle part of the fixing piece is designed to be in contact with the inclined surface of the beveled tooth groove, ensuring that under normal working conditions, the contraction band can stably surround the organ and apply appropriate pressure. When it is necessary to adjust or release the fixation of the contraction band, the medical staff only needs to apply a certain amount of pressure to the pressing part. Under the action of pressure, the buckle part will rotate in the direction away from the beveled tooth groove, thereby easily releasing the cooperation between the fixing seat and the clamping part. Such a design simplifies the adjustment process, allowing medical staff to complete the operation more quickly, and reduces the difficulty of operation and reduces errors caused by improper operation. Due to the interconnection between the buckle part and the pressing part, the entire fixing piece is compact and stable, and is not prone to loosening or falling off, further enhancing the reliability and stability of the artificial contraction structure.

[0011] Furthermore, the fixing seat includes a locking piece, and the fixing seat is provided with a locking hole; the buckle portion is provided with a groove that matches the locking piece, and the locking piece passes through the locking hole and matches with the groove to limit the relative movement of the fixing piece and the fixing seat.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the locking piece on the fixing seat cooperates with the groove on the buckle part, and the relative movement between the fixing piece and the fixing seat is effectively limited by the tight cooperation between the locking piece passing through the locking hole and the groove. This design makes it difficult for the fixing piece to deviate or loosen when subjected to external force, thereby ensuring the stability and reliability of the artificial contraction structure during long-term use. The provision of the locking piece and the locking hole also makes the installation and removal of the fixing piece more convenient. Medical staff only need to perform simple operations to lock and unlock the fixing piece, thereby quickly completing the installation and adjustment of the artificial contraction structure.

[0013] Furthermore, the fixing seat is provided with a clamping groove, and the clamping part is slidably matched with the clamping groove.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the design of the snap-in groove enables the snap-in part to slide along a preset track when it cooperates with the fixing seat, making the installation and adjustment process smoother, reducing unnecessary friction and resistance, and also reducing the difficulty of operation, so that medical staff can complete the installation and adjustment work more quickly and accurately. The sliding fit also enhances the stability of the structure. Since the snap-in part slides in the snap-in groove, its movement trajectory is restricted, thereby effectively preventing the snap-in part from accidentally falling off or shifting during use, ensuring the stability and reliability of the artificial contraction structure during long-term use, and improving the treatment effect and patient experience.

[0015] Furthermore, the artificial contraction structure includes: a transmission device, the transmission device includes a traction wire, one end of the traction wire is fixedly connected to the contraction position of the contraction belt, and the transmission device is used to contract the contraction belt.

[0016] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the contraction and release of the contraction belt is controlled by the transmission device, thereby achieving control over the patient's human organs, and the traction wire can quickly and accurately pull the contraction belt to contract, thereby achieving effective compression of the organs. The transmission device achieves precise control of the contraction belt, improving the efficiency and accuracy of treatment and the comfort of the patient.

[0017] Furthermore, the fixing seat is provided with a through hole, the fixing piece is provided with an opening, and the traction wire passes through the through hole and the opening in sequence.

[0018] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: in order to prevent the normal operation of the traction wire, an opening is opened at the position where the traction wire passes through the fixing piece, so that the traction wire will not be affected by the fixing piece.

[0019] Furthermore, the transmission device includes a flexible tube, and the traction wire is arranged in the inner cavity of the flexible tube.

[0020] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the flexible tube can effectively prevent the traction wire from being disturbed and damaged by the external environment during use, such as friction, pulling, etc., thereby extending the service life of the traction wire. At the same time, the flexible tube can also provide support and guidance for the traction wire to ensure its stability and precision during operation.

[0021] Furthermore, the contraction belt is provided with a receiving groove, and the traction wire is arranged between two ends of the receiving groove.

[0022] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the setting of the storage groove improves the stability and reliability of the traction wire. Since the traction wire is limited in the storage groove, its position is relatively fixed and it is not easy to shift or fall off. It ensures that the traction wire can always maintain a stable connection with the contraction belt during operation, thereby realizing precise control of the contraction belt.

[0023] The utility model also provides a medical device, which comprises the artificial contraction structure provided by the above technical solution.

[0024] After adopting the technical solution of the utility model, the following technical effects can be achieved:

[0025] The contraction band can wrap around the target object by the cooperation of the fixing seat at one end of the contraction band and the clamping part at the other end. This design enables the contraction band to flexibly adapt to organs of different sizes and shapes, thus improving its versatility and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] This embodiment provides an artificial contractile structure, such as Figure 1As shown, the artificial contraction structure includes: a contraction belt 100, a fixing seat 110 is provided at one end of the contraction belt 100, and a clamping portion 130 is provided at the other end, the fixing seat 110 cooperates with the clamping portion 130 so that the contraction belt 100 surrounds the target object; the fixing seat 110 includes a fixing piece 120, and the clamping portion 130 is provided with an oblique tooth groove 131: when the fixing seat 110 cooperates with the clamping portion 130, the fixing piece 120 abuts against the inclined surface of the oblique tooth groove 131 to limit the clamping portion 130 from moving in a direction away from the fixing seat 110.

[0035] Specifically, the target object is a human organ, and the artificial contraction structure surrounds a hollow human organ such as the urethra, rectum, esophagus or stomach. In order to reduce the diameter of the human organ or occlude the human organ, the artificial contraction structure applies pressure to the organ. In particular, in the case of urinary incontinence or fecal incontinence, the artificial contraction structure essentially forms an artificial sphincter that can be opened and closed by controlling the pressure applied by the contraction band 100.

[0036] It should be noted that the shrink band 100 has sufficient hardness so that the shrink band can be bent and wrapped into a hollow structure, and the human organ is arranged in the hollow structure. When the shrink band 100 is wrapped, the fixing seat 110 cooperates with the clamping part 130 to fix the two ends of the shrink band 100, so that the shrink band 100 is wrapped into a hollow structure.

[0037] Specifically, a fixing position 117 is provided on the fixing seat 110, and a clamping groove 114 is provided below the fixing seat 110, the clamping groove 114 is communicated with the fixing position 117, the fixing member 120 is arranged in the fixing position 117, and at least part of the buckle portion 121 of the fixing member 120 extends to the clamping groove 114. When the shrink band 100 is wrapped around, the clamping portion 130 enters the clamping groove 114, and the buckle portion 121 abuts against the inclined surface of the oblique tooth groove 131 to limit the clamping portion 130 from moving away from the fixing seat 110. At this time, the clamping portion 130 can continue to move toward the fixing seat 110 to continue to tighten the shrink band 100.

[0038] Furthermore, the fixing seat 110 is provided with a rotating shaft 111 and an elastic member, and the fixing member 120 is rotatably connected to the fixing seat 110 via the rotating shaft 111; the elastic member is sleeved on the rotating shaft 111 to drive the fixing member 120 to lean against the inclined surface.

[0039] Specifically, the elastic member is sleeved on the rotating shaft 111, driving the buckle portion 121 of the fixing member 120 to press against the inclined surface of the oblique tooth groove 131, so that the clamping portion 130 can only move into the clamping groove 114 but cannot move out of the clamping groove 114, thereby achieving unidirectional locking of the clamping portion 130 by the fixing seat 110.

[0040] Further, such as Figure 4As shown, the fixing member 120 includes a snap portion 121 and a pressing portion 122 connected to each other, and the snap portion 121 is in contact with the inclined surface; wherein, when pressure is applied to the pressing portion 122, the snap portion rotates in a direction away from the oblique tooth groove 131 to release the cooperation between the fixing seat 110 and the snap portion 130.

[0041] Specifically, when the engaging portion 130 needs to be pulled out from the engaging groove 114, it is only necessary to press the pressing portion 122 downward so that the snap-fit ​​portion 121 rotates upward and separates from the oblique tooth groove 131 to release the lock on the engaging portion 130, move the engaging portion 130 outward to the desired position, release the pressing portion 122, and the snap-fit ​​portion 121 will rest against the inclined surface of the oblique tooth groove 131 again under the action of the elastic member, pushing the engaging portion 130 toward the engaging groove 114 for readjustment. The structure is simple and easy to operate.

[0042] Further, such as Figure 2 and Figure 3 As shown, the fixing seat 110 includes a locking piece 112, and the fixing seat 110 is provided with a locking hole 113; the buckle portion 121 is provided with a groove that matches the locking piece 112, and the locking piece 112 passes through the locking hole 113 and matches with the groove to limit the relative movement of the fixing piece 120 and the fixing seat 110.

[0043] Specifically, when the shrink band 100 is adjusted to a suitable position, the locking member 112 is inserted into the locking hole 113 and into the groove 124 of the fixing member 120 to lock the fixing member 120 to prevent the fixing member 120 from loosening and causing the shrink band 100 to fall off.

[0044] Furthermore, the fixing seat 110 is provided with a clamping groove 114 , and the clamping portion 130 is slidably matched with the clamping groove 114 .

[0045] Furthermore, the artificial contraction structure includes: a transmission device 200 , the transmission device 200 includes a traction wire, one end of the traction wire is fixedly connected to the contraction position 115 of the contraction belt 100 , and the transmission device 200 is used to contract the contraction belt 100 .

[0046] Specifically, a fixed seat 110 at one end of the traction wire passes through and is fixedly connected to the contraction position 115 of the contraction band 100. When the contraction band 100 surrounds a human organ and the human organ needs to be occluded, the traction force generated by the traction wire contracts the contraction band 100, thereby occluding the human organ.

[0047] Furthermore, the fixing seat 110 is provided with a through hole, the fixing member 120 is provided with an opening 123 , and the traction wire passes through the through hole and the opening 123 in sequence.

[0048] Specifically, when the traction wire passes through the fixing seat 110, in order to prevent the fixing member 120 from blocking the traction wire, an opening 123 is set on the fixing member 120. The size of the opening 123 should take into account the rotation of the fixing member 120 when the fixing member 120 is pressed, including the traction wire being able to pass through the opening.

[0049] Furthermore, the transmission device 200 includes a flexible tube 210 , and the traction wire is arranged in the inner cavity of the flexible tube 210 .

[0050] Furthermore, the shrink band 100 is provided with a receiving groove 116 , and the traction wire is arranged between two ends of the receiving groove 116 .

[0051] Embodiment 2:

[0052] This embodiment provides a medical device, which includes the artificial contraction structure of the first embodiment.

[0053] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
