Description

Technical Field

[0001] This invention belongs to the field of medical devices, specifically relating to an intraoperative gastrointestinal fistula fixation device. Background Technology

[0002] Gastrointestinal stoma is a common surgical procedure in gastrointestinal surgery. It involves creating an artificial passage between the gastrointestinal tract and the abdominal wall to achieve therapeutic purposes such as drainage, nutritional support, or decompression. During the stoma procedure, the surgeon needs to manage and fix multiple stoma traction sutures to ensure a clear surgical field and smooth operation.

[0003] Currently, in clinical practice, gastrointestinal stoma surgery typically relies on surgeons manually combing and pulling the stoma sutures. However, this traditional method has the following drawbacks: First, manually combed stoma sutures are prone to scattering or piling up around the surgical area, obstructing the surgical view and affecting the surgeon's observation and manipulation of the stoma. Second, multiple stoma sutures are prone to tangling during surgery, increasing the difficulty of counting sutures and potentially leading to accidental pulling, causing tissue damage or requiring secondary suturing. Third, existing traction methods lack effective fixation devices, making it impossible to flexibly adjust the traction direction according to changes in suture position, thus limiting the convenience of the surgical procedure. Therefore, current techniques suffer from the problem of lacking effective fixation devices after suture traction during stoma surgery, resulting in multiple sutures tangling, obstructing the surgical view, and being unable to flexibly adjust the traction direction according to suture angle, thus affecting the efficiency and success rate of the surgical procedure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an intraoperative gastrointestinal fistula fixation device, which solves the problems in existing technologies where there is a lack of effective fixation devices after suture traction during fistula surgery, resulting in multiple sutures becoming entangled and obstructing the surgical field of vision, and the inability to flexibly adjust the traction direction according to the suture angle, thus affecting the efficiency and success rate of surgical operations.

[0005] The objective of this invention can be achieved through the following technical solutions: An intraoperative gastrointestinal fistula fixation device includes a circular fixation ring; Multiple arc-shaped movable plates are arranged circumferentially on the inner peripheral wall of the fixed ring, and the movable plates are all slidably connected to the inner peripheral wall of the fixed ring around the central axis of the fixed ring. Multiple positioning blocks are fixedly connected to each movable plate. The multiple positioning blocks are arranged around the fixed ring. Each positioning block is provided with a groove for fixing the fistula line. Each movable plate is equipped with a locking mechanism, which is used to lock the movable plate in the adjusted position.

[0006] Furthermore, the locking mechanism includes a connecting cylinder, which is fixed to the side of the moving plate away from the central axis of the fixed ring; Multiple arc-shaped grooves are provided on the fixed circumferential wall. The number of arc-shaped grooves is equal to the number of connecting cylinders and they correspond one-to-one. The connecting cylinders slide through the corresponding arc-shaped grooves.

[0007] Furthermore, the locking mechanism also includes a slider that is slidably connected inside the connecting cylinder. The slider extends to the outside of the connecting cylinder from the end away from the moving plate and is fixed with a connecting plate. At least one pin facing the fixing ring is fixed on the connecting plate. Multiple pin holes are provided on the outer peripheral wall of the fixed ring at any position of the arc-shaped slide groove. The pin holes are evenly arranged along the extension direction of the arc-shaped slide groove, and the pin shaft can be slidably inserted into any pin hole at the corresponding arc-shaped slide groove.

[0008] Furthermore, each connecting cylinder is fixedly installed with a spring placed coaxially. The spring is located on the side of the slider away from the connecting plate, and the slider is fixedly connected to one end of the spring.

[0009] Furthermore, a handle is fixed to the end of the connecting plate away from the slider.

[0010] Furthermore, a flange extends inward from the inner peripheral wall of either end of the fixing ring, and an annular groove is provided on the flange that is coaxial with the fixing ring. Each movable plate is fixed with an arc-shaped locking strip, which slides and engages in the circular groove.

[0011] Furthermore, the positioning block has wire-locking grooves on both sides extending circumferentially along the fixing ring.

[0012] Furthermore, an adhesive plate is fixed to either end face of the fixation ring along the axial direction, and the adhesive plate is used to attach and fix the fixation ring to the patient's skin.

[0013] The beneficial effects of this invention are: 1. This application uses a circular fixed ring as the basic support structure and slides multiple arc-shaped movable plates on its inner circumferential wall. At the same time, multiple positioning blocks with suture grooves are arranged on the movable plates, which realizes the orderly fixation of multiple sutures in the fistula surgery. When in use, the doctor can independently slide and adjust each movable plate to the optimal traction position according to the position of the suture needle and reliably lock it through the locking mechanism. This effectively solves the problems of sutures scattering and tangling and obstructing the surgical field of vision, and significantly improves the convenience of surgical operation and the clarity of the field of vision. 2. The outer side adjusts the inner side moving plate through the cooperation of the connecting cylinder and the arc-shaped sliding groove. The sliding pin shaft and the evenly distributed pin holes are used to achieve multi-position precise locking. A spring is set to prevent the pin shaft from accidentally loosening to improve the locking stability. The sliding engagement of the circular groove and the locking strip enhances the guidance and connection stability of the moving plate. The positioning block has wire grooves on both sides to double the fixing points to reduce the risk of entanglement. The adhesive plate allows the device to be quickly and firmly fixed to the patient's skin and is easy to remove after surgery, taking into account both the convenience of operation and the safety of the patient.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1 to 6 As shown, an intraoperative gastrointestinal fistula fixation device includes a circular fixation ring 100; Multiple arc-shaped movable plates 200 are arranged circumferentially on the inner peripheral wall of the fixed ring 100. The movable plates 200 are all slidably connected to the inner peripheral wall of the fixed ring 100 around the central axis of the fixed ring 100. Multiple positioning blocks 300 are fixedly connected to each movable plate 200. The multiple positioning blocks 300 are arranged circumferentially along the fixing ring 100. Each positioning block 300 is provided with a wire-locking groove 301 for fixing the stoma line. Each movable plate 200 is equipped with a locking mechanism 400, which is used to lock the movable plate 200 in the adjusted position; In use, the doctor first places the circular fixing ring 100 on the skin around the patient's stoma. Then, according to the specific position and angle requirements of the sutures during surgery, the doctor slides and adjusts multiple arc-shaped movable plates 200 along the inner circumferential wall of the fixing ring 100. Since the movable plates 200 are all slidably connected to the inner circumferential wall of the fixing ring 100, each movable plate 200 can move independently and smoothly along the circumference of the fixing ring 100, thus flexibly adjusting to the most suitable position for traction of the stoma line. Once the movable plate 200 is adjusted to the required position, the locking mechanism 400 on the movable plate 200 reliably locks it in its current position to prevent damage during surgery. Accidental contact caused the movable plate 200 to shift; then, the doctor sequentially inserted the stoma suture into the suture slot 301 on the positioning block 300 for fixation; each movable plate 200 is fixedly connected to multiple positioning blocks 300 arranged circumferentially along the fixing ring 100, providing sufficient fixing points for the stoma suture; through the above structure, multiple movable plates 200 achieve zoned and orderly management of the stoma suture, effectively avoiding the problems of stoma sutures tangling and obstructing the surgical field of vision; at the same time, the adjustable position of the movable plate 200 allows the doctor to make adaptive adjustments according to the traction direction of different sutures, greatly facilitating the surgical operation and improving the success rate and safety of the operation; Preferably, one end of the positioning block 300 extends axially along the fixing ring 100 to the outside of the fixing ring 100 to ensure that the suture groove 301 is located outside the fixing ring 100, which facilitates the fixation of the stoma suture.

[0018] The locking mechanism 400 includes a connecting cylinder 401, which is fixed to the side of the movable plate 200 away from the central axis of the fixed ring 100; Multiple arc-shaped grooves 101 are provided on the periphery of the fixed ring 100. The number of arc-shaped grooves 101 is equal to that of the connecting cylinders 401 and they correspond one-to-one. The connecting cylinders 401 slide through the corresponding arc-shaped grooves 101. By setting up the connecting cylinder 401 and the arc-shaped slide groove 101, the connecting cylinder 401 is pushed to move along the corresponding arc-shaped slide groove 101, and the moving plate 200 is driven by the connecting cylinder 401, so as to realize the position adjustment of each moving plate 200 on the outside of the fixed ring 100.

[0019] The locking mechanism 400 also includes a slider 402 slidably connected inside the connecting cylinder 401. The end of the slider 402 away from the moving plate 200 extends to the outside of the connecting cylinder 401 and is fixed to the connecting plate 403. At least one pin 404 facing the fixing ring 100 is fixed on the connecting plate 403. Multiple pin holes 102 are provided on the outer peripheral wall of the fixing ring 100 at any position of the arc-shaped slide groove 101. The pin holes 102 are evenly arranged along the extension direction of the arc-shaped slide groove 101. The pin shaft 404 can be slidably inserted into any pin hole 102 at the corresponding arc-shaped slide groove 101. When the movable plate 200 is adjusted to the desired position, the sliding slider 402 moves the connecting plate 403 toward the fixing ring 100, thereby inserting the pin 404 into the corresponding pin hole 102, thus fixing the connecting cylinder 401 and the fixing ring 100, locking the movable plate 200 in the current position. When the position of the movable plate 200 needs to be adjusted again, the sliding slider 402 is reversed to disengage the pin 404 from the pin hole 102, releasing the locking state, and the movable plate 200 can slide freely again. This structure achieves precise locking of the position of the movable plate 200 through the insertion and engagement of the pin 404 and the pin hole 102. The operation is simple and reliable, and the even arrangement of multiple pin holes 102 provides multi-level adjustment function, which can adapt to the needs of different surgical angles. Preferably, each connecting plate 403 has two symmetrically arranged pins 404, and each arc-shaped groove 101 has two rows of pin holes 102, with the two rows of pin holes 102 corresponding one-to-one with the two pins 404 on the connecting plate 403; by inserting the two pins 404 into the two pin holes 102 at the same time, the stability of the fit between the pin holes 102 and the pins 404 is improved.

[0020] Because the pin 404 on the periphery is prone to accidentally slipping out of the pin hole 102 under the influence of gravity when the fixed ring 100 is placed at different angles, causing the locking to be unstable, in order to solve the above problem, springs 405 placed in the same axis are fixedly installed inside the connecting cylinder 401. The springs 405 are located on the side of the slider 402 away from the connecting plate 403, and the slider 402 is fixedly connected to one end of the spring 405. When the position of the movable plate 200 needs to be adjusted, pull the connecting plate 403 to move it away from the movable plate 200. At the same time, the connecting plate 403 pulls the spring 405 to extend until the connecting plate 403 drives the pin to be pulled out of the pin hole 102, and the position of the movable plate 200 can be adjusted. When the movable plate 200 is adjusted to the desired position, slowly release the connecting plate 403 so that the pin 404 is inserted into the pin hole 102 at the desired position. With the elastic force of the spring 405, the pin 404 can be prevented from accidentally slipping out of the pin hole 102, which further improves the stability when locking the movable plate 200.

[0021] A handle 406 is fixed to the end of the connecting plate 403 away from the slider 402; the handle 406 is provided to facilitate the movement of the connecting plate 403.

[0022] A flange 103 extends inward from the inner peripheral wall of any end of the fixing ring 100, and an annular groove 104 is provided on the flange 103 and is placed coaxially with the fixing ring 100. Each movable plate 200 is fixed with an arc-shaped locking strip 201, and the locking strip 201 is slidably engaged in the annular groove 104; By using the combination of the clip 201 and the annular groove 104, the guiding properties of the moving plate 200 during movement are improved, and the stability of the connection between the moving plate 200 and the fixed ring 100 is also improved, thus preventing the moving plate 200 from separating from the fixed ring 100. Preferably, the cross-section of the retaining strip 201 along the axial direction is convex, and the cross-section of the annular groove 104 is concave to match it, so as to ensure effective sliding engagement between the retaining strip 201 and the annular groove 104.

[0023] The positioning block 300 has suture grooves 301 on both sides extending circumferentially along the fixing ring 100. In a limited space, two stoma sutures can be fixed at the same time by one positioning block 300, which realizes the multiplication of fixing points, facilitates the zoned management of multiple sutures, and effectively avoids the mutual entanglement and interference of stoma sutures.

[0024] An adhesive plate 500 is fixed to any end face of the fixing ring 100 along the axial direction. The adhesive plate 500 is used to attach and fix the fixing ring 100 to the patient's skin. The adhesive plate 500 is used to fix the gastrointestinal fistula fixator to the patient's skin. Preferably, the adhesive plate 500 can be made of medical pressure-sensitive adhesive, such as acrylic pressure-sensitive adhesive or silicone gel pressure-sensitive adhesive, to ensure good biocompatibility and skin affinity, while possessing sufficient adhesive strength to ensure the device remains stable and does not shift during surgery. The shape of the adhesive plate 500 is preferably a ring structure that matches the fixation ring 100, so as to be evenly distributed on the end face of the fixation ring 100. To prevent the adhesive plate 500 from being contaminated or its adhesive strength from decreasing before use, its surface is covered with a peelable dustproof film, which can be made of paper material coated with a release agent or PET film. During use, the doctor only needs to peel off the dustproof film to directly attach the fixation ring 100 to the patient's skin through the adhesive plate 500, making the operation simple and quick. After surgery, the adhesive plate 500 can be gently peeled off from the skin along with the fixation ring 100, avoiding secondary damage to the patient.
