Welding device with temperature control function for medical anastomat

Abstract

The application discloses a welding device with temperature control function for a medical anastomat, and relates to the technical field of anastomat welding devices. The device comprises a base, a machine case, an electric door opening, a welding assembly, a discharging port and a precision control device. When fixed, the device drives a pre-tightening turnover device to displace twice by using a clamping sliding block, so that a fixing pin is inserted into a rotating hole in the end of an upper cover to complete positioning of the end of the upper cover. Then, the device drives a pre-tightening ring to rotate and extrude a pre-tightening spring by using a displacement of a pushing end, so that the pre-tightening spring applies a pre-tightening force to a fixing head to make the fixing head generate a torque. Under the action of the torque, the upper cover is closely attached to a nail abutting seat, and the effect of fixing and stacking of the upper cover and the nail abutting seat is achieved. The pre-tightening spring in a pre-tightening state is used to make the fixing head deflect the finished product welding piece to the discharging port, so that the pre-tightening force is converted into rotation to achieve the effect of auxiliary discharging. The damping effect of the second extrusion piece is used to make the pre-tightening spring slowly rebound, so that the fixing head is prevented from deflecting too fast to cause bumping of the welding piece.

TECHNICAL FIELD

[0001] The present application relates to the technical field of anastomat welding device, and particularly relates to a medical anastomat welding device with temperature control function. BACKGROUND

[0002] The medical anastomat replaces traditional manual suturing through mechanical stapling technology, is mainly used for rapid connection and repair of tissues or organs such as gastrointestinal, blood vessels and lungs, and can not only significantly improve the operation efficiency, but also effectively reduce postoperative complications such as liquid leakage and infection. In the production process of the anastomat, a butt joint seat needs to be welded on the upper cover of the anastomat clamp head, and the upper cover is usually composed of a U-shaped strip and an end head. The butt joint seat is welded with the U-shaped strip to form a U-shaped weld seam, and the end head is provided with a rotating hole on both sides for rotating and installing the upper cover at the clamp head.

[0003] However, there is a lack of full-automatic high-precision welding equipment specially used for welding the butt joint seat and the upper cover of the anastomat in the existing market. Many existing anastomat manufacturers still rely on manual welding. Even if there is some automatic welding equipment, the butt joint seat and the upper cover are still manually clamped by workers. This method is not only low in efficiency, but also depends on the experience and technology of the workers, so that the quality of the welded parts produced is uneven. SUMMARY

[0004] The present application aims to provide a medical anastomat welding device with temperature control function to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a medical anastomat welding device with temperature control function, comprising a base, a machine box is installed on the base, a precision control device is slidingly installed on the base, a discharging port is arranged on the base, a welding assembly is arranged on the base, and an electric door is arranged on the machine box; the precision control device comprises an electric sliding support, the electric sliding support is slidingly installed on the base, a butt joint seat roller assembly is rotatably installed on the electric sliding support, locking assemblies are symmetrically installed on the electric sliding support, and an upper cover fixing device is slidingly installed on the electric sliding support.

The electric sliding support can slide along the track on the base. An upper feeding device is connected to the machine box, and the upper feeding device is used for placing the butt joint seat and the upper cover on the precision control device.

[0007] During machining, the control system opens the electric door, controls the electric sliding support to slide out, and uses the external loading device to place the anvil on the bottom roller, engaging the anvil's nail groove with the limit teeth. The control system then activates the electric telescopic rods, and the output shafts on both sides of the electric telescopic rods drive the locking plates to lock the rotating shaft. The limit teeth restrict the anvil from moving in the same plane. Afterwards, the loading device overlaps the U-shaped strip of the upper cover on the anvil and places the upper cover end on the bracket, completing the loading process.

[0009] The electric slider can slide along the track on the electric sliding support after being powered.

[0010] After loading is completed, the control system starts the servo motor, and the output shaft of the servo motor drives the gear to rotate a preset number of circles. The gear drives the racks on both sides to slide on the electric slider, and the racks drive the two clamping sliders to slide closer. The clamping sliders drive the pre-tightening flipping device to move closer. During the approach process, the fixed head on the pre-tightening flipping device pushes the end of the upper cover to move to the middle until the fixed head contacts both sides of the upper cover end. The upper cover is centered under the push of the fixed heads on both sides.

[0011] Furthermore, the pre-tightening flipping device includes a propulsion end, which is installed on the clamping slider, a sliding ring is slidably installed on the propulsion end, a clamping spring is installed between the sliding ring and the propulsion ring, a pre-tightening ring is movably installed on the propulsion end, the pre-tightening ring is rotatably connected to the sliding ring, a fixed head is rotatably installed at one end of the sliding ring, the fixed head is rotatably connected to the pre-tightening ring, a pre-tightening spring is installed between the pre-tightening ring and the fixed head, a bracket is installed at the bottom end of the fixed head, and an annular gasket is installed on the fixed head.

[0012] The annular gasket is used to protect the end of the upper cover to prevent clamping marks from appearing on the end of the upper cover. It also increases the friction between the fixed head and the end of the upper cover to prevent sliding between the fixed head and the end of the upper cover during clamping.

[0013] After the upper cover is centered, the control system further starts the servo motor, the servo motor drives the gear to rotate, the gear further drives the clamping slider to move close through the toothed belt, because the fixed head is against the two sides of the end of the upper cover, the fixed head cannot move close, with the clamping slider driving the advancing end to further move, the push head pushes the fixed pin to extend the fixed head and penetrate into the rotating hole of the end of the upper cover, the positioning of the end of the upper cover is completed; during the movement of the fixed pin, the transmission column on the fixed pin extrudes the pre-tightening ring through the inclined slot, drives the pre-tightening ring under pressure to rotate around the center axis thereof, the first extrusion piece rotates with the pre-tightening ring and compresses the pre-tightening spring, after the pre-tightening spring is compressed, the elastic force is transmitted to the second extrusion piece, the second extrusion piece drives the fixed head to generate a torque rotating around the center axis of the fixed pin, so that the fixed head has a tendency to drive the upper cover to rotate around the fixed pin, under the action of the torque, the upper cover is closely attached to the nail abutting seat, the effect of fixing the upper cover and the nail abutting seat to be stacked is achieved, so that the upper cover and the nail abutting seat are prevented from being dislocated during welding, and the welding precision is affected.

[0014] Further, the advancing end comprises a push head, the push head is installed on the clamping slider, one end of the push head is provided with a fixed pin, one end of the push head is symmetrically provided with a positioning rod, the fixed pin is symmetrically provided with a transmission column, the positioning rod is in sliding connection with the sliding ring, the fixed pin is in movable connection with the pre-tightening ring, the transmission column is in sliding connection with the pre-tightening ring, and the fixed pin is in sliding connection with the sliding ring.

[0016] The second damping block adopts a column structure and is semi-embedded in the slide way. When the end of the positioning rod is retracted in the slide way, the two second damping blocks will generate slight friction with the end of the positioning rod, the relative movement speed between the positioning rod and the sliding ring is slowed down through the friction force, and the damping effect is achieved.

[0017] Further, the pre-tightening ring is symmetrically provided with a first extrusion piece, the first extrusion piece is connected with one end of the pre-tightening spring, the pre-tightening ring is provided with an inclined slot, the transmission column is slidably installed in the inclined slot, one end of the pre-tightening ring is provided with a second rotating ring, and the second rotating ring is rotatably installed in the second rotating groove.

[0019] The first damping block adopts a columnar structure and is semi-embedded in the spring groove. When the compressed pre-tightening spring rebounds, the first damping blocks on both sides will slightly rub against the pre-tightening spring, thereby slowing down the rebound speed of the pre-tightening spring through friction, allowing the pre-tightening spring to slowly rebound and achieving a damping effect.

[0020] After the welding is completed, the control system causes the electric telescopic rod to drive the locking plate to retract, causing the rotating shaft to be unlocked, and then the electric sliding block is turned on, the electric sliding block drives the upper cover fixing device with the upper cover fixed thereon to move, the upper cover drives the nail seat welded thereon to slide on the bottom support roller, the nail groove on the nail seat drives the limiting teeth to rotate, the limiting teeth drive the bottom support roller to rotate, and the bottom support roller and the limiting teeth rotate to assist in discharging, thereby avoiding the nail seat from being directly scraped on the surface of the limiting block and preventing the nail seat from being scratched.

[0021] When the nail seat and the upper cover completely slide away from the bottom support roller, the pre-tightening spring slowly rebounds under the action of the first damping block due to the loss of support at the bottom of the nail seat, the pre-tightening spring slowly rotates the fixing head through the second extrusion piece, the fixing head drives the nail seat and the upper cover to deflect downward around the fixing pin to the discharging groove, and then the control system turns on the servo motor to cause the clamping sliding block to drive the pre-tightening turnover device to loosen the fixation of the nail seat and the upper cover, and the nail seat and the upper cover enter the discharging opening from the discharging groove and slide into the finished product collection place along the discharging channel in the base, thereby completing the discharging of the finished welded product.

[0022] After the pre-tightening turnover device is loosened, the clamping spring inside rebounds to push the sliding ring to slide along the positioning rod, the sliding ring slowly slides under the action of the second damping block, the sliding ring pushes the pre-tightening ring to move forward during the sliding process, the pre-tightening ring rotates forward under the action of the transmission column and the inclined groove, the first extrusion piece on the pre-tightening ring rotates the fixing head through the pre-tightening spring to reset, and when the clamping spring completely rebounds, the pre-tightening turnover device is completely reset, thereby completing the entire welding process, and the process is repeated to realize the automatic welding of the upper cover and the nail seat.

[0023] Further, the electric sliding support is provided with a discharging groove, the electric sliding support is provided with a mounting seat, the mounting seat is rotatably provided with a nail seat roller assembly, and the mounting seat is symmetrically provided with a locking assembly.

[0024] After the fixing and stacking are completed, the control system controls the electric sliding support to slide into the machine box until the discharging groove on the electric sliding support is located above the discharging opening, the control system turns on the welding assembly, and the welding assembly welds the U-shaped seam between the upper cover and the nail seat.

[0025] Further, the nail seat roller assembly includes a plurality of rotating shafts, the rotating shafts are rotatably installed on the mounting seat, the rotating shafts are provided with bottom support rollers, the bottom support rollers are provided with a plurality of limiting teeth, the end of the rotating shaft is designed as a rough surface, the rotating shaft is provided with a plurality of transmission teeth, the rotating shaft is provided with a transmission belt, the transmission belt is in meshing transmission with the transmission teeth, and the limiting teeth are matched with the shape of the nail groove of the nail seat.

[0028] The rough surface design of the locking plate and the end of the rotating shaft can generate high friction when the two are attached, so that the rotating shaft cannot rotate under the action of the friction, achieving the purpose of locking the supporting roller.

[0029] Compared with the prior art, the present application has the following beneficial effects:

[0030] 1. The gear and rack are used to make the clamping slider drive the pre-tightening turnover device to push the end of the upper cover to displace, so as to achieve the purpose of centering the upper cover. The limiting teeth are designed to match the shape of the nail grooves of the nail seat, so that the limiting teeth can be embedded with the nail grooves of the nail seat. When the supporting roller is locked, the purpose of preventing the nail seat from displacing in the plane is achieved. The rough surface design of the locking plate and the end of the rotating shaft can generate high friction when the two are attached, so that the rotating shaft cannot rotate, achieving the purpose of locking the supporting roller.

[0031] 2. When fixed, the clamping slider drives the pre-tightening turnover device to displace again, so that the fixing pin penetrates into the rotating hole of the end of the upper cover to complete the positioning of the end of the upper cover. Then the displacement of the pushing end drives the pre-tightening ring to rotate and press the pre-tightening spring, so that the pre-tightening spring exerts a pre-tightening force on the fixing head to generate a torque. Under the action of the torque, the upper cover is closely attached to the nail seat, achieving the effect of fixing the upper cover and the nail seat in a stacked manner, improving the stability, preventing the upper cover and the nail seat from moving during welding, and affecting the welding precision.

[0032] 3. During the unloading process, the supporting roller is unlocked, and the supporting roller and the limiting teeth rotate to assist unloading, avoiding the nail seat directly sliding on the surface of the limiting block and scratching the nail seat, achieving the purpose of protecting the pre-tightening state welding part during unloading.

[0033] 4. The pre-tightening spring in the pre-tightening state uses the resilience to make the fixing head deflect to the unloading port, achieving the effect of converting the pre-tightening force into rotation for assisting unloading. The damping effect of the second pressing piece makes the pre-tightening spring slowly rebound, avoiding the fixing head deflecting too fast to cause the knocking of the welding part, and improving the safety.

[0034] 5. The second damping block slows down the rebound speed of the fixing head driven by the sliding ring when the clamping slider drives the pre-tightening turnover device to move, so that the fixing head can first break the contact with the finished welding part, and the welding part can first fall off, completing the rapid unloading.

Since the fixed head 84 abuts against the two sides of the end head of the upper cover, the fixed head 84 cannot move to approach, and as the clamping sliding block 623 drives the advancing end 81 to further move, the push head 811 pushes the fixed pin 813 to extend out of the fixed head 84 and penetrate into the rotating hole of the end head of the upper cover, and the positioning of the end head of the upper cover is completed; in the moving process of the fixed pin 813, the transmission column 814 thereon extrudes the pre-tightening ring 87 through the inclined slot 872, drives the pre-tightening ring 87 under pressure to rotate around its central axis, the first extrusion piece 871 rotates with the pre-tightening ring 87 and compresses the pre-tightening spring 88, the pre-tightening spring 88 transmits the elastic force to the second extrusion piece 843 after being compressed, the second extrusion piece 843 drives the fixed head 84 to generate a torque around the central axis of the fixed pin 813, so that the fixed head 84 has a tendency to drive the upper cover to rotate around the fixed pin 813, and under the action of the torque, the upper cover is closely attached to the nail holder, so that the effect of fixed stacking of the upper cover and the nail holder is achieved, and the misalignment between the upper cover and the nail holder during welding is prevented, so as to affect the welding precision.

[0073] When the nail seat and the upper cover completely slide away from the bottom support roller 631, the pre-tightening spring 88 starts to slowly rebound under the action of the first damping block 844, the pre-tightening spring 88 drives the fixed head 84 to slowly rotate through the second extrusion piece 843, the fixed head 84 drives the nail seat and the upper cover to deflect downward around the fixed pin 813 to the discharging groove 611, then the control system opens the servo motor 622 in the direction, so that the clamping sliding block 623 drives the pre-tightening turnover device 8 to loosen the fixing of the nail seat and the upper cover, the nail seat and the upper cover enter the discharging port 5 from the discharging groove 611, slide into the finished product collecting place along the discharging channel in the base 1, so as to complete the discharging of the finished product welding piece.

[0074] After the pre-tightening turnover device 8 is loosened, the clamping spring 82 rebounds and pushes the sliding ring 83 to slide along the positioning rod 812, the sliding ring 83 slowly slides under the action of the second damping block 834, the sliding ring 83 pushes the pre-tightening ring 87 to move forward in the sliding process, the pre-tightening ring 87 rotates while moving forward under the action of the transmission column 814 and the inclined groove 872, the first extrusion piece 871 on the pre-tightening ring 87 drives the fixed head 84 to rotate and reset through the pre-tightening spring 88, and when the clamping spring 82 completely rebounds, the pre-tightening turnover device 8 is completely reset. Thus, the whole welding process is completed, and the automatic welding of the upper cover and the nail seat is realized through the cycle.
