At the same time, the smoking hood is detachably arranged at the front end of the pen body, so that the smoking hood can be synchronously replaced after the cutter head is replaced, enabling the generated smoke to be absorbed in the first time, preventing the smoke that needs to be cleared in time from blocking the surgical area, reducing the doctor's recognition of tissue structures, increasing the surgical risk, and improving the surgical efficiency.

Description

Technical Field

[0001] The present invention belongs to the field of electrosurgical knives, and particularly relates to a smoking knife capable of quickly replacing a smoke suction cover and a knife head and an automatic assembly device thereof. Background Art

[0002] An electrosurgical pen is a medical device widely used in surgical operations, which realizes functions such as tissue cutting, hemostasis, and coagulation through high-frequency current. However, when using an electrosurgical pen for surgery, a large amount of surgical smoke will be generated. This smoke not only obscures the surgical field of view but may also contain harmful substances, posing a potential threat to the health of medical staff and patients. To solve this problem, a smoking electrode knife (integrating a smoke suction function) is introduced into the surgery, which can effectively remove surgical smoke and improve the surgical environment.

[0003] In actual surgeries, doctors may need to switch to using electrode knives of different lengths according to the surgical situation. However, the existing smoking surgical knives can be telescoped, but only the knife head is telescoped, and the length of the smoke suction cover remains unchanged, resulting in the inability to absorb the smoke generated immediately. The smoke that is not cleared in time will obscure the surgical area, reduce the doctor's recognition of tissue structures, increase the surgical risk, and reduce the surgical efficiency.

[0004] In the assembly and production process, the manufacturing of surgical electrosurgical pens highly depends on manual operations, with low production efficiency and easy errors. The position of the knife head is the part that directly contacts the human body, and manual assembly is prone to introducing contamination (such as fingerprints and particulate residues), affecting the product cleanliness, while the requirements for a sterile environment in medical devices are extremely strict. Therefore, it is necessary to propose a smoking knife capable of quickly replacing a smoke suction cover and a knife head and an automatic assembly device thereof. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art and provide a smoking knife capable of quickly replacing a smoke suction cover and a knife head and an automatic assembly device thereof.

[0006] The above technical object of the present invention is achieved through the following technical solutions:

[0007] A smoking knife capable of quickly replacing a smoke suction cover and a knife head includes a pen body, a conductive elastic member, a circuit board, an electrode knife head, and a smoke suction cover. The circuit board is arranged inside the pen body. The smoke suction cover is detachably arranged at the front end of the pen body. The conductive elastic member is arranged at the lower end of the circuit board. The electrode knife head is arranged inside the smoke suction cover and extends into the pen body and is detachably inserted into the conductive elastic member. The conductive elastic member closely adheres to the outer side wall of the electrode knife head. The smoke suction cover can match different lengths of smoke suction covers according to the length of the electrode knife head.

[0008] In the present invention, the electrode cutter head is inserted into the conductive elastic member, and the conductive elastic member is closely attached to the outer side wall of the electrode cutter head, so as to achieve detachable replacement of the cutter head while ensuring electrical connection. At the same time, the smoke suction hood is detachably arranged at the front end of the pen body, so that the smoke suction hood can be synchronously replaced after the cutter head is replaced, so as to absorb the generated smoke in the first time, prevent the timely cleared smoke from blocking the surgical area, reduce the doctor's recognition of tissue structure, increase the surgical risk, and improve the surgical efficiency.

[0009] Preferably, clamping grooves are formed on the side wall of the front end of the pen body, the two clamping grooves are arranged oppositely, clamping blocks are formed on the outer side wall of the smoke suction hood and are matched with the clamping grooves, and a rotating track is formed on the side wall of the front end of the pen body to facilitate the rotating clamping of the clamping blocks into the clamping grooves.

[0010] In the present invention, the clamping blocks on the smoke suction hood are rotated and clamped into the clamping grooves through the rotating track, so as to achieve convenient disassembly of the smoke suction hood.

[0011] The bottom of the conductive elastic member is open, and the cross section is triangular. Three outward claw petals are formed on one side of the conductive elastic member close to the front end of the pen body to facilitate the insertion of the electrode cutter head.

[0012] Preferably, limiting strips are formed on the side wall of the clamping groove close to the front end of the pen body, and limiting grooves are formed on the clamping blocks and are matched with the limiting strips to strengthen the clamping effect.

[0013] Preferably, the pen body is divided into an upper pen body and a lower pen body. A partition is arranged on the lower pen body. A smoke suction channel is formed between the partition and the bottom of the lower pen body. Side plates are arranged between the partition and the front end of the lower pen body. Electrode cutter head through holes are formed on the side plates. A tail plug is arranged at the tail of the lower pen body. A smoke suction pipe connection port is arranged on the tail plug. A notch is formed on the top of the tail plug. A limiting ring is formed on the outer side wall of the tail plug. The limiting ring is used to prevent the tail plug from being inserted too far. The notch is convenient for the installation of the wire on the circuit board. The tail plug is convenient for the insertion of the subsequent smoke suction pipe.

[0014] In the present invention, the circuit board is installed above the smoke suction channel through the partition to protect the circuit board while smoking.

[0015] The electrode cutter head includes a cutter handle and a cutter head.

[0016] An automatic assembly device for a smoking knife capable of quickly replacing a smoke suction hood and a cutter head includes a machine frame, a conveyor belt arranged on the machine frame. A plurality of lower pen body baffles are evenly distributed along the conveying direction of the conveyor belt. A placement space for placing the lower pen body is arranged between every two adjacent lower pen body baffles. A tail plug insertion area, a circuit board placement area, an upper pen body pressing area, an ultrasonic heat sealing area, and an electrode cutter head insertion area are sequentially arranged along the conveying direction of the conveyor belt. In the whole device, for more convenience, four pen bodies can be set to operate simultaneously.

[0017] In the present invention, the lower pen body can be placed on the conveyor belt through the placement space 62 on the conveyor belt, so that the lower pen body can move to different workstations along with the conveyor belt. When passing through the tail plug insertion area, the tail plug can be automatically inserted. When passing through the printed circuit board placement area, the printed circuit board can be manually placed. When passing through the upper pen body pressing area, the upper pen body can be automatically pressed onto the lower pen body. Then, automatic heat sealing is performed through the ultrasonic heat sealing area. Then, the electrode knife head is automatically inserted into the pen body through the electrode knife head insertion area. Then, tests are carried out through the function test area. The entire production of the product, including the automatic feeding, assembly, ultrasonic heat sealing of plastic parts, etc. of each part, is completed by the automation of the equipment. For the entire production, few personnel are involved, and errors in manual assembly are avoided, which can greatly ensure the high feasibility and consistency of multiple batches of products.

[0018] The tail plug insertion area includes a tail plug feeding cylinder, a tail plug transfer cylinder, a rotating shaft, a rotating motor, a telescopic plate, and a tail plug insertion electric push rod. The tail plug feeding cylinder is arranged on the side of the conveyor belt and fixedly connected to the frame. The tail plug transfer cylinder is arranged below the tail plug feeding cylinder and its bottom is a closed end. The rotating shaft is arranged at the bottom of the tail plug feeding cylinder. The rotating motor is arranged at one end of the rotating shaft. One of the tail plug insertion electric push rods is fixedly connected to the rotating shaft, and the other tail plug insertion electric push rod is fixedly connected to the rotating motor. The two tail plug insertion electric push rods are fixed on the frame, and the rotating motor is fixed on the frame. The telescopic plate is arranged between the tail plug feeding cylinder and the tail plug transfer cylinder. The telescopic plate is pushed back and forth by an electric push rod. The telescopic plate is provided with a tail plug discharge port. A vibration motor can be installed on the tail plug transfer cylinder to facilitate the positioning of the tail plugs that fall into the cylinder.

[0019] In the present invention, the tail plugs are arranged in the tail plug feeding cylinder from bottom to top. The mouth of the tail plug transfer cylinder is upward. When discharging is required, the telescopic plate retracts backward so that the tail plug discharge port aligns with the tail plug feeding cylinder. One tail plug drops downward from the tail plug discharge cylinder into the tail plug transfer cylinder. Then, the telescopic plate immediately moves forward to block the tail plug discharge port. Then, the tail plug transfer cylinder is flipped 90° by the rotating motor so that the tail plug transfer cylinder aligns with the placement space. Then, the tail plug insertion electric push rod drives the tail plug transfer cylinder to move to the conveyor belt, so that the tail plug is inserted into the rear end of the lower pen body. Then, the tail plug insertion electric push rod drives the tail plug transfer cylinder to return to its original position, thus completing the automatic insertion of the tail plug.

[0020] Preferably, the tail plug feeding cylinder and the tail plug transfer cylinder are both provided with positioning blocks along the axial direction that cooperate with the notches of the tail plugs. The length of the positioning block located in the tail plug transfer cylinder is the length from the limiting ring to the end of the tail plug, ensuring positioning while not preventing the tail plug from being inserted into the lower pen body.

[0021] The present invention can position the tail plug through the positioning block, preventing the tail plug from moving within the tail plug feeding cylinder and the tail plug transfer cylinder, which may affect the subsequent assembly.

[0022] Preferably, the electrode tool head insertion area includes a vibrating bowl, a tool head adjustment and installation mechanism, a vision system, a feeding box, a tool head conveyor belt, and a tool head pressing member. The tool head adjustment and installation mechanism is provided at the discharge port of the vibrating bowl. The vision system is provided above the tool head adjustment and installation mechanism. The feeding box is provided behind the tool head adjustment and installation mechanism. The tool head conveyor belt is provided behind the feeding box. The conveying direction of the tool head conveyor belt is the same as that of the conveyor belt and is located on the side of the conveyor belt. The tool head pressing member is provided on the side of the tool head conveyor belt. A conveying track is provided between the vibrating bowl and the tool head adjustment and installation mechanism. The vibrating bowl is a prior art, so it will not be elaborated in this case. The vision system includes an industrial camera, an image processor, etc., which are prior arts, so they will not be elaborated in this case.

[0023] In the present invention, the electrode tool heads are poured into the vibrating bowl. The vibrating bowl aligns the axes of the electrode tool heads automatically with the conveying track, and then they are successively conveyed to the tool head adjustment and installation mechanism. The vision system determines whether the direction of the electrode tool heads is correct. If it is incorrect, the direction is adjusted (always keeping the tool handle of the electrode tool head facing the feeding box). Then, they fall into the feeding box and are conveyed by the tool head conveyor belt to the front of the tool head pressing member. Then, they are conveyed by the tool head pressing member to the conveyor belt and inserted into the pen body to complete the automatic installation of the electrode tool heads.

[0024] Preferably, the tool head adjustment and installation mechanism includes a rotating disk, a retaining ring, a downwardly inclined discharge plate, a rotary cylinder, and a guiding plate. The rotary cylinder is provided on the frame. The rotating disk is provided on the top of the rotary cylinder. The retaining ring is provided outside the rotating disk. The guiding plate is provided in the middle of the rotating disk. A guiding groove is provided on the guiding plate. Feeding ports and discharge ports are provided at the positions corresponding to both ends of the guiding plate on the retaining ring. The feeding port is connected to the discharge port of the vibrating bowl, and the discharge port is connected to the discharge plate. The end of the discharge plate is provided on the feeding box. A roller can be installed at the discharge port of the retaining ring to facilitate the conveyance of the electrode tool heads onto the discharge plate.

[0025] In the present invention, the electrode tool heads are conveyed into the guiding groove of the guiding plate through the feeding port of the retaining ring. When the direction needs to be rotated, the direction is adjusted by the rotary cylinder. When the direction does not need to be adjusted, the conveyance continues forward.

[0026] Preferably, the tool head extruding member includes a hollow extrusion block, an extrusion electric push rod, and a special-shaped clamping mechanism. The rear end of the extrusion block is a closed end, and the front end is an opening. The extrusion electric push rod is arranged at the rear end of the extrusion block, and the special-shaped clamping mechanism is arranged inside the extrusion block. The special-shaped clamping mechanism includes a left clamping member and a right clamping member. There is a gap between the left clamping member and the right clamping member. Both the left clamping member and the right clamping member include a clamping block and a compression spring. The compression spring is arranged between the clamping block and the side wall of the extrusion block. A number of clamping blocks and compression springs are arranged in an array.

[0027] In the present invention, when the extrusion block extrudes towards the electrode tool head through the gap, the electrode tool head can be pushed into the extrusion block. Then, due to the elastic force of the compression spring, the clamping block clamps the electrode tool head. Since there are multiple clamping blocks, no matter what direction the tool head of the electrode tool head is in, it can be clamped. Then, the electrode tool head follows the extrusion block and is pushed into the pen body on the conveyor belt. After that, the tool head extruding member returns to its original position through the extrusion electric push rod, completing the automatic assembly of the electrode tool head.

[0028] A vertically telescopic blocking plate is arranged opposite to the tool head conveyor belt relative to the tool head extruding member. The blocking plate can be telescoped through an electric push rod. When the electrode tool head is still on the tool head conveyor belt and the blocking plate rises, when the extrusion block moves towards the conveyor belt, the electrode tool head can be extruded into the extrusion block. When it is necessary to convey the electrode tool head to the conveyor belt, the blocking plate descends.

[0029] The tool head conveyor belt includes a conveyor belt body, and an electrode tool head limiting groove is formed on the conveyor belt body, so that when the tool head conveyor belt passes through the feeding box, the electrode tool head can be taken away.

[0030] The upper pen body pressing area includes a slide rail, a pen body electric push rod, a connecting plate, a suction cup, and a lower pen body placement box. The slide rail is arranged on the frame. The pen body electric push rod is slidably arranged below the slide rail. The sliding direction of the slide rail is perpendicular to the conveying direction of the conveyor belt. The connecting plate is arranged at the push rod end of the pen body electric push rod. The suction cup is arranged below the pen body electric push rod. The lower pen body placement box is arranged on the side of the conveyor belt. The lower pen body placement box is provided with a plurality of partitions, which are convenient for arranging the lower pen bodies in the required directions and placing them in the lower pen body placement box.

[0031] In the present invention, through the slide rail and the pen body electric push rod, the suction cup sucks up the upper pen in the pen body placement box and then presses it down onto the lower pen body.

[0032] Pressing mechanisms are arranged in both the tail plug insertion area and the electrode tool head insertion area. The pressing mechanism is composed of a pressing plate and an electric push rod, which prevent the pen body from shifting when the tail plug and the electrode tool head are inserted.

[0033] The conveyor belt is also provided with a function test area, which consists of a pressing electric push rod and a pressing block. When passing through the function test area, a low-voltage current is input. The low-voltage test line passes the low-voltage current through the cutter head part for low-voltage testing. The pressing electric push rod presses the coagulation button and the cutting button of the electric scalpel pen. The function test is prior art, so it will not be elaborated in this case.

[0034] In summary, the beneficial effects of the present invention are as follows:

[0035] 1. In the present invention, the electrode cutter head is inserted into the conductive elastic member, and the conductive elastic member closely adheres to the outer side wall of the electrode cutter head, realizing detachable replacement of the cutter head while ensuring electrical connection. At the same time, the smoke suction hood is detachably arranged at the front end of the pen body, so that the smoke suction hood can be synchronously replaced after the cutter head is replaced, so as to absorb the generated smoke in the first time, prevent the timely cleared smoke from blocking the surgical area, reduce the doctor's recognition of tissue structure, increase the surgical risk, and improve the surgical efficiency.

[0036] 2. In the present invention, the lower pen body can be placed on the conveyor belt through the placement space on the conveyor belt, so that the lower pen body can move to different workstations along with the conveyor belt. When passing through the tail plug insertion area, the tail plug can be automatically inserted. When passing through the circuit board placement area, the circuit board can be manually placed. When passing through the upper pen body pressing area, the upper pen body can be automatically pressed onto the lower pen body. Then, automatic heat sealing is carried out through the ultrasonic heat sealing area. Then, the electrode cutter head is automatically inserted into the pen body through the electrode cutter head insertion area. Then, tests are carried out through the function test area. The entire production of the product, including automatic feeding, assembly, ultrasonic heat sealing of plastic parts, etc. of each part, is completed by equipment automation. In the whole production process, few people are involved, avoiding errors in manual assembly, and greatly ensuring the high feasibility and consistency of multi-batch products.

[0037] 3. In the present invention, the tail plugs are arranged in the tail plug feeding cylinder from bottom to top. The mouth of the tail plug transfer cylinder is upward. When discharging is required, the telescopic plate retracts backward so that the tail plug discharge port is aligned with the tail plug feeding cylinder. One tail plug drops down into the tail plug transfer cylinder. Then the telescopic plate immediately moves forward to block the tail plug discharge port. Then the tail plug transfer cylinder is flipped 90° by the rotating motor so that the tail plug transfer cylinder is aligned with the placement space. Then the tail plug insertion electric push rod drives the tail plug transfer cylinder to move to the conveyor belt, so that the tail plug is inserted into the rear end of the lower pen body. Then the tail plug insertion electric push rod drives the tail plug transfer cylinder to return to its original position, thus completing the automatic insertion of the tail plug.

[0038] 4. In the present invention, the electrode cutter heads are poured into the vibrating bowl. Through the vibrating bowl, the axes of the electrode cutter heads are automatically aligned with the conveying track, and then they are successively conveyed to the cutter head adjustment and installation mechanism. The vision system is used to judge whether the directions of the electrode cutter heads are correct. If not, the directions are adjusted (always keeping the handles of the electrode cutter heads facing the feeding box). Then, they fall into the feeding box and are conveyed by the cutter head conveyor belt to the front of the cutter head extruding part. After that, they are conveyed by the cutter head extruding part to be inserted into the pen body through the conveyor belt, completing the automatic installation of the electrode cutter heads.

[0039] 5. When the extrusion block squeezes towards the electrode cutter head through the gap in the present invention, the electrode cutter head can be pushed into the extrusion block. Then, due to the elastic force of the compression spring, the clamping block clamps the electrode cutter head. Since there are multiple clamping blocks, the cutter head of the electrode cutter head can be clamped regardless of its direction. Then, the electrode cutter head follows the extrusion block and is pushed into the pen body on the conveyor belt. After that, the cutter head extruding part returns to its original position through the extrusion electric push rod, completing the automatic assembly of the electrode cutter head.

[0067] Working principle: As Figures 1 - 19 shown in the figure, when the automatic assembly equipment is in use, the partition of the lower pen body 12 is placed upward on the conveyor belt 6. Then the conveyor belt 6 drives the lower pen body 12 to move to the tail plug insertion area 7. The mouth of the tail plug transfer cylinder 72 is upward. The telescopic plate 75 retracts backward so that the tail plug discharge port is aligned with the tail plug feeding cylinder 71. One tail plug drops from the tail plug feeding cylinder 71 into the tail plug transfer cylinder 72. Then the telescopic plate immediately moves forward to block the tail plug feeding cylinder 71. Then the tail plug transfer cylinder 72 is flipped 90° by the rotation motor 74 so that the tail plug transfer cylinder 72 is aligned with the placement space 62. Then the tail plug insertion electric push rod 76 drives the tail plug transfer cylinder 72 to move onto the lower pen body 12 on the conveyor belt, so that the tail plug 125 is inserted into the rear end of the lower pen body 12. Then the tail plug insertion electric push rod 76 drives the tail plug transfer cylinder 72 to return to its original position to perform the work of the next tail plug. The lower pen body with the inserted tail plug moves to the circuit board placement area 70. The circuit board is placed on the lower pen body manually. Then it moves to the upper pen body pressing area 80. The suction cup is driven by the slide rail 801 to move above the lower pen body placement box 805 to suck the upper pen body 11. Then it moves above the conveyor belt 6. The pen body electric push rod 802 presses down to initially press the upper pen body 11 above the lower pen body 12. Then it undergoes ultrasonic heat sealing in the ultrasonic heat sealing area. Then it is conveyed to the electrode knife head insertion area 8. The electrode knife heads are arranged on the knife head conveyor belt first. The extrusion block 861 moves towards the conveyor belt direction through the extrusion electric push rod 862. During the movement, the electrode knife head 4 is pushed into the extrusion block 861. Then the electrode knife head 4 follows the extrusion block and is pushed into the pen body on the conveyor belt 6 by the extrusion block 861. Then the extrusion block 861 returns to its original position through the extrusion electric push rod 862 to complete the automatic assembly of the electrode knife head. Then functional testing is carried out to eliminate unqualified products. The qualified products are then assembled with the smoking hood and the tail smoking pipe. Through the automatic assembly equipment, the whole production involves few personnel, avoids errors in manual assembly, can greatly ensure the high feasibility of the products and the consistency of multi-batch products. Especially for the position of the knife head, automatic assembly is adopted, which greatly reduces the direct contact of the human body and reduces pollution.
