Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an anastomosis reinforcement and leak prevention device for sleeve gastrectomy. Background Technology

[0002] With the continuous development of medical device technology, electric staplers are gradually replacing traditional manual sutures or conventional staplers. Electric staplers utilize electric drive systems and automated control technology, enabling rapid and accurate connection and closure of tissues during surgery. This significantly reduces surgical time and trauma, minimizes the risk of tissue damage, bleeding, and infection, and promotes patient recovery and healing. Furthermore, electric staplers can provide consistent anastomosis force and pressure, unaffected by variations in manual operation, thus lowering the technical requirements for the operator.

[0003] Sleeve gastrectomy is a common surgical procedure for treating obesity and related metabolic diseases. Strengthening and preventing leakage at the anastomosis is crucial for surgical safety, directly impacting postoperative recovery and complication rates. In this delicate procedure, surgeons must hold the anastomosis device for extended periods. The surgical field is narrow and the operating space is limited, requiring the hand to remain stable while performing precise movements. Minor adjustments to hand posture or hand tremors caused by unforeseen circumstances during surgery are difficult to completely avoid. However, existing anastomosis devices used in this surgery generally have significant defects. The most prominent one is that the drive buttons on the operating handle lack reliable protective structures. These drive buttons are often directly exposed and have a short trigger stroke. During the operation, frequent hand movements, adjustments to the grip posture, or accidental contact between surgical instruments can easily trigger the drive buttons. Once the drive button is accidentally triggered, it will directly cause the jaws at the front of the device to open or close unexpectedly or deflect at an angle. If the jaws are in a critical position during the anastomosis reinforcement operation, it may not only damage the initially formed anastomosis structure but also cause pinching or tearing of the surrounding fragile gastric wall tissue, thereby increasing the risk of surgical errors.

[0004] In view of this, we propose an anastomosis reinforcement and leak prevention device for sleeve gastrectomy. Summary of the Invention

[0005] The purpose of this invention is to provide an anastomosis reinforcement and leak prevention device for sleeve gastrectomy, in order to solve the problem mentioned in the background art where the drive buttons lack a reliable protective structure. These drive buttons are often directly exposed and have a short trigger stroke. During surgery, frequent hand movements, adjustments to grip posture, or accidental contact between surgical instruments can easily cause accidental activation of the drive buttons. Once the drive button is accidentally activated, it will directly cause the jaws at the front end of the device to open or close unexpectedly or deflect at an angle. If the jaws are in a critical position during the anastomosis reinforcement operation, it may not only damage the initially formed anastomosis structure, but also cause pinching or tearing of the surrounding fragile gastric wall tissue, thereby increasing the risk of surgical errors. To achieve the above objectives, the present invention provides the following technical solution: an anastomosis reinforcement and leak prevention device for sleeve gastrectomy, comprising a handle, a control frame fixedly connected to the top of the handle, a drive block fixedly connected to the side of the control frame, an annular groove on the left side of the control frame, a connecting block rotatably connected to the side of the inner wall of the annular groove, a support rod fixedly connected to the left side of the connecting block, a jaw fixedly connected to the left end of the support rod, a drive button fixedly connected to the left side of the handle, a moving groove on the bottom of the handle, a protective component for preventing accidental contact slidably connected inside the moving groove, an installation chamber on the right side of the handle, and a power supply block disposed inside the installation chamber.

[0006] Preferably, the protective component includes a T-shaped strip, which is slidably connected inside the movable groove. An L-shaped plate is fixedly connected to the bottom of the T-shaped strip. A rectangular groove is provided on the side of the vertical plate of the L-shaped plate. The L-shaped strip is slidably connected inside the rectangular groove. The overall position can be adjusted by the sliding cooperation between the T-shaped strip and the movable groove. The sliding of the L-shaped strip in the rectangular groove provides a degree of freedom of movement for the protective structure, so that the protective component can be stably installed on the handle and the protective position can be flexibly adjusted according to the operation requirements, providing multi-dimensional protective space for the drive button.

[0007] Preferably, the drive button has a groove inside, and a locking block is fixedly connected to the top of the horizontal bar of the L-shaped strip. The locking block and the side of the horizontal bar of the L-shaped strip are slidably connected to the inside of the groove. A first compression spring is fixedly connected to the bottom of the horizontal bar of the L-shaped strip. The bottom end of the first compression spring is fixedly connected to the bottom of the inner wall of the rectangular groove. The cooperation between the locking block and the groove allows the L-shaped plate and the drive button to form a precise engagement. The elastic force of the first compression spring can push the L-shaped strip to automatically reset, ensuring that the locking block is always engaged in the groove when not in operation.

[0008] Preferably, the bottom of the drive button has an elongated groove, the front side of the inner wall of the elongated groove is fixedly connected to a second compression spring, the side of the inner wall of the elongated groove is slidably connected to a T-shaped block, one side of the T-shaped block is fixedly connected to the other end of the second compression spring, the bottom of the vertical block of the T-shaped block is fixedly connected to the top of the horizontal plate of the L-shaped plate, the sliding cooperation between the T-shaped block and the elongated groove provides guidance for the horizontal movement of the L-shaped plate, and the second compression spring can be pulled to automatically return to its original position after the L-shaped plate is unlocked.

[0009] Preferably, a slot is provided on the upper side of the inner wall of the movable groove, the side of the vertical bar of the L-shaped strip slides into the side of the inner wall of the slot, and a circular groove is provided on the side of the connecting block. The number of circular grooves is several, and the several circular grooves are equally spaced and arranged in a ring on the side of the connecting block. The side of the vertical bar of the L-shaped strip slides into the interior of one of the circular grooves. The cooperation between the vertical bar of the L-shaped strip and the slot further improves the installation stability of the protective component and prevents it from shaking in the protective state. The interlocking structure of the vertical bar and the ring-shaped grooves can simultaneously fix the rotation position of the connecting block when the protective component is locked, preventing the jaws from rotating accidentally when not in operation, ensuring accurate positioning of the jaws during surgery, and improving the safety of the anastomosis reinforcement operation.

[0010] Preferably, a protective plate is fixedly connected to the left side of the power block, and the protective plate is the same size as the control frame. Two mounting plates are fixedly connected to the right side of the protective plate. Mounting ports that mate with the mounting plates are opened on the right sides of both the front and rear sides of the control frame. The design of the protective plate being the same size as the control frame can achieve complete sealing protection of the mounting chamber, preventing body fluids and impurities from entering the mounting chamber and damaging the power block during the operation. The precise matching of the mounting plates and mounting ports provides a quick positioning and installation structure for the power block, simplifies the disassembly and assembly process of the power block, and facilitates power replacement and device maintenance before and after the operation.

[0011] Preferably, the protective plate has a through groove inside, and connecting grooves are formed on both the front and rear sides of the inner wall of the through groove. A C-shaped rod is arranged inside the through groove, and a round block is fixedly inserted into the side of the vertical rod of the C-shaped rod. A torsion spring is fixedly sleeved on both the front and rear sides of the side of the round block. One end of the torsion spring is fixedly connected to one side of the connecting groove, and the other end of the torsion spring is fixedly connected to the side of the vertical rod of the C-shaped rod. The torsion spring provides a continuous elastic force to the C-shaped rod through the cooperation of the round block and the connecting groove, so that the C-shaped rod always maintains a stable locked posture and prevents it from loosening during device vibration or operation.

[0012] Preferably, a fixing groove is provided on the side of the inner wall of the mounting port, and an insert rod is fixedly connected to the side of the vertical rod of the C-shaped rod. The side of the insert rod slides in cooperation with the side of the inner wall of the fixing groove. The precise fitting of the insert rod and the fixing groove can form a rigid connection between the protective plate and the control frame, avoiding relative displacement between the protective plate and the control frame during surgical operations.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the T-shaped strip of the protective component is slidably connected to the moving groove of the handle, so that the L-shaped plate can stably cover the outside of the drive button. The locking block at the top of the L-shaped strip fits into the groove, and with the elastic restoring force of the first compression spring, it is ensured that the locking block is always locked in the groove, forming double protection, effectively avoiding accidental contact with the drive button during surgery and reducing the risk of operational errors.

[0014] In this invention, the L-shaped strip moves downward to compress the first compression spring, causing the locking block to disengage from the groove and the vertical strip of the L-shaped strip to exit the circular groove. At this time, the connecting block can rotate along the annular groove of the control frame, thereby driving the support rod and the jaws to adjust to the required deflection angle. After adjustment, the L-shaped strip is released, the first compression spring pushes the L-shaped strip to reset, and the vertical strip of the L-shaped strip is re-embedded into the circular groove at the corresponding position. This achieves the fixation of the position of the L-shaped plate after movement and the angle limitation of the support rod, completing the positioning without additional operation and improving surgical efficiency.

[0015] In this invention, the mounting plate on the side of the protective plate is inserted into the mounting port of the control frame. When the power block is disassembled, the C-shaped rod is lifted upward and the torsion spring is compressed, which drives the plug rod to exit the fixing groove of the mounting port. At this time, the protective plate and the power block can be directly pulled out. When the power block is replaced, the mounting plate is aligned with the mounting port and pushed in, and the torsion spring drives the plug rod to automatically lock into the fixing groove. Thus, the overall operation is more convenient and meets the needs of quickly changing the power supply before and after surgery. Attached Figure Description

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.

[0019] Please see Figures 1 to 9 The present invention provides a technical solution: an anastomosis reinforcement and leak prevention device for sleeve gastrectomy, comprising a handle 1, a control frame 2 fixedly connected to the top of the handle 1, a drive block 3 fixedly connected to the side of the control frame 2, an annular groove 4 opened on the left side of the control frame 2, a connecting block 5 rotatably connected to the side of the inner wall of the annular groove 4, a support rod 6 fixedly connected to the left side of the connecting block 5, a jaw 7 fixedly connected to the left end of the support rod 6, a drive button 8 fixedly connected to the left side of the handle 1, a moving groove 9 opened at the bottom of the handle 1, a protective component 10 for preventing accidental contact slidably connected inside the moving groove 9, and an installation chamber 11 opened on the right side of the handle 1, with a power block 12 disposed inside the installation chamber 11.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9As shown, the protective component 10 includes a T-shaped strip 1001, which is slidably connected inside the movable groove 9. An L-shaped plate 1002 is fixedly connected to the bottom of the T-shaped strip 1001. A rectangular groove 1003 is provided on the side of the vertical plate of the L-shaped plate 1002. An L-shaped strip 1004 is slidably connected inside the rectangular groove 1003. The overall position adjustment is achieved through the sliding cooperation between the T-shaped strip 1001 and the movable groove 9. The sliding of the L-shaped strip 1004 in the rectangular groove 1003 provides a degree of freedom of movement for the protective structure, so that the protective component 10 can be stably installed on the handle 1 and the protective position can be flexibly adjusted according to the operation requirements, providing a multi-dimensional protective space for the drive button 8.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the drive button 8 has a groove 801 inside. The top of the horizontal bar of the L-shaped bar 1004 is fixedly connected to a locking block 1005. The locking block 1005 and the side of the horizontal bar of the L-shaped bar 1004 are slidably connected to the inside of the groove 801. The bottom of the horizontal bar of the L-shaped bar 1004 is fixedly connected to a first compression spring 1006. The bottom end of the first compression spring 1006 is fixedly connected to the bottom of the inner wall of the rectangular groove 1003. The cooperation between the locking block 1005 and the groove 801 makes the L-shaped plate 1002 and the drive button 8 precisely engaged. The elastic force of the first compression spring 1006 can push the L-shaped bar 1004 to automatically reset, ensuring that the locking block 1005 is always engaged in the groove 801 when not in operation.

[0022] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, a long groove 802 is provided at the bottom of the drive button 8. A second compression spring 803 is fixedly connected to the front side of the inner wall of the long groove 802. A T-shaped block 804 is slidably connected to the side of the inner wall of the long groove 802. One side of the T-shaped block 804 is connected to the other end of the second compression spring 803. The bottom of the vertical block of the T-shaped block 804 is fixedly connected to the top of the horizontal plate of the L-shaped plate 1002. The sliding cooperation between the T-shaped block 804 and the long groove 802 provides guidance for the horizontal movement of the L-shaped plate 1002. The second compression spring 803 can be pulled to automatically return to its original position after the L-shaped plate 1002 is unlocked.

[0023] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9As shown, a slot 901 is provided on the upper side of the inner wall of the movable groove 9. The side of the vertical bar of the L-shaped bar 1004 slides and engages with the side of the inner wall of the slot 901. A circular groove 501 is provided on the side of the connecting block 5. There are several circular grooves 501, which are equidistantly arranged in a ring on the side of the connecting block 5. The side of the vertical bar of the L-shaped bar 1004 slides and engages with the inside of one of the circular grooves 501. The engagement between the vertical bar of the L-shaped bar 1004 and the slot 901 further enhances the installation stability of the protective component 10 and prevents it from shaking in the protective state. The interlocking structure of the vertical bar and the circularly distributed grooves 501 can simultaneously fix the rotation position of the connecting block 5 when the protective component 10 is locked, preventing the jaws 7 from rotating accidentally when not in operation, ensuring the accurate positioning of the jaws 7 during surgery, and improving the safety of the anastomosis reinforcement operation.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, a protective plate 1201 is fixedly connected to the left side of the power block 12. The protective plate 1201 is the same size as the control frame 2. Two mounting plates 1202 are fixedly connected to the right side of the protective plate 1201. Mounting ports 1203 that cooperate with the mounting plates 1202 are opened on the right side of both the front and rear sides of the control frame 2. The design of the protective plate 1201 being the same size as the control frame 2 can achieve complete sealing protection of the installation chamber 11, preventing body fluids and impurities from entering the installation chamber 11 and damaging the power block 12 during the operation. The precise cooperation between the mounting plates 1202 and the mounting ports 1203 provides a quick positioning and installation structure for the power block 12, simplifying the disassembly and assembly process of the power block 12 and facilitating power replacement and device maintenance before and after the operation.

[0025] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, the protective plate 1201 has a through groove 1204 inside. The inner wall of the through groove 1204 has connecting grooves 1205 on both the front and back sides. A C-shaped rod 1206 is installed inside the through groove 1204. A round block 1207 is fixedly inserted into the side of the vertical rod of the C-shaped rod 1206. A torsion spring 1208 is fixedly sleeved on both the front and back sides of the round block 1207. One end of the torsion spring 1208 is fixedly connected to one side of the connecting groove 1205, and the other end of the torsion spring 1208 is fixedly connected to the side of the vertical rod of the C-shaped rod 1206. The torsion spring 1208 provides a continuous elastic force to the C-shaped rod 1206 through the cooperation of the round block 1207 and the connecting groove 1205, so that the C-shaped rod 1206 always maintains a stable locked posture and prevents it from loosening during device vibration or operation.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 9 As shown, a fixing groove 1209 is provided on the side of the inner wall of the mounting port 1203. The side of the vertical rod of the C-shaped rod 1206 is fixedly connected to the insertion rod 1210. The side of the insertion rod 1210 slides and engages with the side of the inner wall of the fixing groove 1209. The precise engagement of the insertion rod 1210 and the fixing groove 1209 can form a rigid connection between the protective plate 1201 and the control frame 2, thus preventing relative displacement between the protective plate 1201 and the control frame 2 during surgical operations.

[0027] The method of use and advantages of the present invention: The anastomosis reinforcement and leak prevention device for sleeve gastrectomy works as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figures 8 to 9 As shown, the T-shaped strip 1001 of the protective component 10 is slidably connected to the moving groove 9 of the handle 1, so that the L-shaped plate 1002 can stably cover the outside of the drive button 8. The locking block 1005 at the top of the L-shaped strip 1004 is precisely engaged with the groove 801 of the drive button 8. With the elastic restoring force of the first compression spring 1006, it can ensure that the locking block 1005 is always locked in the groove 801 when not in operation, forming double protection, effectively avoiding accidental contact with the drive button 8 during surgery and reducing the risk of operational errors. By pressing the L-shaped strip 1004, the first compression spring 1006 can be compressed, causing the locking block 1005 to disengage from the groove 801 and driving the vertical strip of the L-shaped strip 1004 to exit the circular groove 501. At this time, the connecting block 5 can rotate along the annular groove 4 of the control frame 2, thereby driving the support rod 6 and the jaw 7 to adjust to the required deflection angle. After the adjustment is completed, the L-shaped strip 1004 is released, the first compression spring 1006 pushes the L-shaped strip 1004 to reset, and the vertical strip of the L-shaped strip 1004 is re-embedded into the corresponding circular groove 501. Thus, the position of the L-shaped plate 1002 after movement is fixed and the angle of the support rod 6 is limited. Positioning can be completed without additional operation, improving surgical efficiency. The power block 12 is fixedly connected to the protective plate 1201. The mounting plate 1202 on the side of the protective plate 1201 is inserted into the mounting port 1203 of the control frame 2. When the power block 12 is disassembled, the C-shaped rod 1206 is lifted upward and the torsion spring 1208 is compressed, which will drive the insertion rod 1210 out of the fixing groove 1209 of the mounting port 1203. At this time, the protective plate 1201 and the power block 12 can be directly pulled out. When the power block 12 is replaced, the mounting plate 1202 is aligned with the mounting port 1203 and pushed in, and the torsion spring 1208 drives the insertion rod 1210 to automatically lock into the fixing groove 1209. The whole process does not require tools, is easy to operate, and meets the needs of quickly changing the power supply before and after surgery.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
