Description

Technical Field

[0001] This invention relates to the field of anastomosis technology, specifically to a tracking electric laparoscopic anastomosis device with absorbable needle thread. Background Technology

[0002] With the rapid development of the biomedical engineering industry, minimally invasive surgery, with its significant advantages such as small trauma, rapid postoperative recovery, and fewer complications, has been widely applied in various clinical fields, including gastrointestinal surgery, thoracic surgery, and hepatobiliary and pancreatic surgery. As a core instrument in minimally invasive surgery, the performance of laparoscopic anastomoses directly affects surgical safety, anastomosis quality, and postoperative healing outcomes. Among these, the tracking-type electric laparoscopic anastomose with absorbable sutures has become a common type in clinical applications. The absorbable sutures are integrally formed from an absorbable needle body and absorbable suture, and are completely biodegradable and absorbable after implantation. The tracking function, through corresponding mechanical or electronic control structures, enables real-time monitoring and limiting of the instrument's firing stroke, tissue anastomosis trajectory, and suture working status, effectively improving the accuracy of the anastomosis operation and reducing intraoperative errors.

[0003] Existing electric laparoscopic staplers work by using an internal linkage support to close the front staple cartridge, precisely clamping the tissue to be anastomosed. The operator then presses a safety switch to activate the handle, which triggers a microswitch. This activates the electric drive mechanism (mainly a drive motor and gear set), moving the rack along a preset trajectory and simultaneously moving the blades inside the staple cartridge to cut and suture the clamped tissue. However, if the electric drive mechanism malfunctions—for example, if the drive motor burns out, the gears jam or wear, or there is poor electrical contact—the motor will stop working and cannot output power. Consequently, the rack cannot be driven to reciprocate. In this situation, the blades inside the staple cartridge cannot advance to complete the cutting and suturing, nor can they retract to detach from the tissue, causing the stapler to jam. This interrupts the surgical procedure and delays the patient's treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a tracking electric laparoscopic stapler with absorbable suture needles to solve the problem mentioned in the background art where, when the electric drive mechanism malfunctions, the blade inside the staple cartridge can neither continue to advance to complete the cutting and suturing nor retract to detach from the tissue, causing the stapler to become stuck, which will interrupt the surgical process and delay the treatment of the patient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tracking electric endoscopic stapler with absorbable suture needle, comprising a housing, a closing handle rotatably installed inside the housing, a linkage bracket fixedly connected to the closing handle, an operating mechanism disposed at one end of the linkage bracket, and a limiting mechanism and an electric drive mechanism disposed inside the housing.

The drive power supply is fixedly installed inside the housing, and the transmission gear is fixedly connected to the output shaft end of the drive power supply. The transmission gear meshes with the transmission rack.

[0009] Preferably, the adjusting mechanism includes a threaded rod and a limiting rod. The threaded rod is rotatably installed inside the housing and threadedly connected to one end of the lifting frame. The limiting rod is slidably sleeved on one end of the lifting frame and is fixedly installed inside the housing.

[0010] Preferably, the first transmission mechanism includes a fixed bracket, a transmission bracket, and a translation component. The top of the fixed bracket is fixedly connected to the outer shell. A top block is slidably installed inside the fixed bracket. A transmission rod is fixedly installed on one side of the top block. Guide rods are slidably sleeved at both ends of the transmission bracket. The bottoms of the two guide rods are fixedly connected to the mounting bracket. A transmission groove is opened inside the transmission bracket. The end of the transmission rod away from the top block is slidably installed inside the transmission groove. The side of the transmission bracket away from the fixed bracket is fixedly connected to the lifting frame.

[0011] Preferably, the translation component includes a transmission block, the transmission block has a transmission groove II inside, a transmission rod II is slidably installed inside the transmission groove II, both sides of the transmission rod II are fixedly connected to the lifting frame, the bottom of the transmission block is slidably connected to the sliding bracket, and a push rod is fixedly installed on one side of the transmission block.

[0012] Preferably, the locking mechanism includes a mounting base 1, with fixed base 1 slidably mounted at both ends of the mounting base 1, and locking blocks slidably mounted at the bottom of each of the two fixed base 1s. The two locking blocks face opposite directions, and spring 1 is fixedly mounted between the top of each locking block and the inner wall of its corresponding fixed base 1. Spring 2 is fixedly mounted between the interior of each of the two fixed base 1s and the inner wall of the mounting base 1.

[0013] Preferably, the connecting mechanism includes a second mounting base, which is fixedly connected to the closing handle. Two fixed bases are slidably mounted on both ends of the second mounting base. A connecting block is slidably fitted onto the top of each of the two fixed bases, with the two connecting blocks facing opposite directions. A spring three is fixedly mounted between the bottom of each connecting block and the inner wall of its corresponding fixed base.

Sliding blocks are rotatably installed at both ends of the linkage rod. The two sliding blocks are slidably connected to their respective fixed seats and lifting plates.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes an adjustment mechanism to position the lifting frame at different locations. Under the action of the first transmission mechanism, the structures in the locking mechanism and connecting mechanism are switched. When the closing handle is manually pressed, the transmission rack can be moved, thereby enabling the blade inside the staple cartridge to advance or retract. This solves the problem that when the motor drive mechanism malfunctions, the transmission rack cannot drive the blade to move, and the blade cannot continue to advance to complete the cutting and suturing, nor can it retract to detach from the tissue, causing the stapler to become stuck, interrupting the surgical process, and delaying the patient's treatment. This further improves the reliability and clinical applicability of electric staplers in the biomedical engineering industry.

[0016] 2. During the horizontal movement of the transmission block, the present invention drives the push rod connected to it to move synchronously. The push rod acts on the limiting bracket, causing the limiting bracket to rotate. The limiting bracket no longer limits the linkage bracket. When the operator presses the closing handle multiple times in the future, it is not necessary to always push the limiting bracket to release the limitation on the closing handle, thus ensuring the continuity of the operator pressing the closing handle.

[0030] Working principle: In use, first press the closing handle 2, which drives the linkage bracket 3 and the operating mechanism 44 to move synchronously. Under the action of the linkage bracket 3, the front staple cartridge closes, precisely clamping the tissue to be anastomosed. Then, the operator controls the operating mechanism 44, which transmits a signal to the drive power supply 7, driving the transmission gear 8 to rotate. At this time, the transmission rack 10 and the sliding bracket 9 move synchronously, and the sliding block 13 slides inside the U-shaped frame 12. As the transmission rack 10 moves, it drives the blade inside the staple cartridge to move, thereby cutting the tissue. Immediately afterwards, the absorbable sutures inside the staple cartridge... When the tissue is sutured, the transmission rack 10 moves to its limit position when it touches the corresponding stop 43, and the blade inside the staple cartridge also moves to its limit position. Then, the operator pushes the limiting bracket 6, which rotates around the rotating axis 4 to release the limit on the linkage bracket 3. Immediately afterwards, the transmission gear 8 reverses, and the transmission rack 10 resets until it touches the corresponding stop 43, at which point the transmission rack 10 stops moving. The operating mechanism 44, how the signal is transmitted to the drive power supply 7, how the blade inside the staple cartridge moves, and how the absorbable needle sutures the tissue are all existing technologies and will not be described in detail here. When the electric drive mechanism malfunctions, rotating the threaded rod 15 causes the lifting frame 14 to move downward under the action of the limit rod 16. The position of the lifting frame 14 can be observed through the transparent observation window 45. During the first stage of descent, the lifting frame 14 drives the transmission rod 25 to descend synchronously. The transmission rod 25 first moves downward in the inclined area of ​​the transmission groove 24. The transmission block 23 then drives the sliding bracket 9 and the transmission rack 10 to move synchronously. The transmission rack 10 no longer meshes with the transmission gear 8. Subsequently, the transmission rod 25 slides to the vertical area of ​​the transmission groove 24. During the descent of the lifting frame 14, the transmission bracket 20 moves steadily downward along the two guide rods 21. Under the action of the transmission groove 22, the transmission rod 19 drives the top block 18 to move horizontally. During the horizontal movement of the transmission block 23, it drives the push rod 46 connected to it to move synchronously. The push rod 46 acts on the limit bracket 6, causing the limit bracket 6 to rotate. The limit bracket 6 no longer limits the linkage bracket 3. When the operator presses the closing handle 2 multiple times in the future, it is not necessary to always push the limit bracket 6 to release the limit on the closing handle 2, thus ensuring the continuity of the operator pressing the closing handle 2. Subsequently, the threaded rod 15 is rotated to lower the lifting frame 14 to the second stage. At this time, the top block 18 slides synchronously and touches the fixed seat 28 near the top block 18. The fixed seat 28 is forced to move downward, which drives the corresponding locking block 29 to move downward synchronously. At the same time, under the action of the corresponding linkage rod 41, the sliding blocks 42 at both ends of the linkage rod 41 slide inside the corresponding fixed seat 28 and the lifting plate 40. The corresponding lifting plate 40 moves upward along the two guide rods 39. The lifting plate 40 pushes up the corresponding short rod 38. The short rod 38 drives the corresponding fixed seat 33 to move upward. At this time, the connecting block 34 moves upward. Next, the operator can press the closing handle 2, causing the connected mounting base 32 to move synchronously. The raised connecting block 34 extends into the corresponding groove 11 at the bottom of the sliding bracket 9. As the closing handle 2 rotates, the raised connecting block 34 can push the sliding bracket 9 to move. After the closing handle 2 moves the mounting base 32 to its limit position, the descending locking block 29 then engages with the corresponding groove 11 at the top of the sliding bracket 9, fixing the position of the sliding bracket 9. Then, the closing handle 2 is released, and under the action of the elastic element (it should be noted that the linkage bracket 3 is connected through a corresponding mechanism)... The blades in the staple cartridge act on the elastic element within the structure (the elastic element is existing technology and will not be described in detail here). When the closing handle 2 is reset, the raised connecting block 34 is reset in the opposite direction. During the reverse rotation, the connecting block 34 touches the sliding bracket 9 and presses the corresponding spring 35. The connecting block 34 then retracts into the fixed seat 2 33 until it moves into the corresponding groove 11. Under the action of the spring 35, the connecting block 34 moves upward and repositions itself in the corresponding groove 11. Then, the closing handle 2 is pressed again to achieve continuous movement of the transmission rack 10, allowing the blades inside the staple cartridge to cut the tissue. After the cutting and stitching is completed, continue to rotate the threaded rod 15 to lower the lifting frame 14 to the third stage. At this time, the top block 18 acts on the more distant fixed seat 28, while the more nearby fixed seats 28 and 33 are reset under the action of their respective springs 30 and 35. Under the action of the more distant second transmission mechanism, the more distant fixed seat 28, the locking block 29, the 33, and the connecting block 34 extend. When the closing handle 2 is pressed again, the transmission rack 10 is reset. By adjusting the lifting frame 14 to different positions using the adjustment mechanism, the structures in the locking mechanism and connecting mechanism are switched under the action of the first transmission mechanism. When the closing handle 2 is manually pressed, the transmission rack 10 can be moved, thereby advancing or retracting the blade inside the staple cartridge. This solves the problem that when the motor drive mechanism malfunctions, the transmission rack 10 cannot drive the blade to move, and the blade cannot continue to advance to complete the cutting and suturing, nor can it retract to detach from the tissue, causing the stapler to become stuck, interrupting the surgical process, and delaying the patient's treatment. This further improves the reliability and clinical applicability of electric staplers in the biomedical engineering industry.
