Description

Technical Field

[0001] The present invention relates to a medical device, and more particularly to a bipolar electrocoagulation dissection forceps hook. Background Art

[0002] Laparoscopy is a newly developed minimally invasive surgical method and an inevitable trend in the development of surgery in the 21st century. At present, laparoscopy can be used in most gynecological surgeries, such as uterine fibroids, ovarian tumors, cervical cancer, endometrial cancer, ovarian cancer, endometriosis, etc. In endoscopic abdominal surgery, usually several small holes are made in the abdomen, and trocars are inserted. Surgical instruments such as laparoscopes and abdominal surgical forceps enter the abdominal cavity through the trocars. The doctor observes the situation inside the abdominal cavity through the laparoscope and uses the abdominal surgical forceps to clamp, grasp, traction, fix, and dissect tissues and organs during the operation. However, the existing abdominal surgical forceps often have a single function and can only complete a single clamping function or dissection and shearing function, etc. This causes the doctor to constantly replace the surgical forceps during the laparoscopic surgery, prolonging the operation time and bringing greater pain to the patient. At the same time, the existing surgical forceps do not have a temperature control function, and it is inevitable to have eschar burns caused by too high temperature. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background art and provide a bipolar electrocoagulation dissection forceps hook.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions:

[0005] A bipolar electrocoagulation dissection forceps hook includes a handle and a multi-functional forceps head provided at the front end of the handle. The multi-functional forceps head includes a first forceps head and a second forceps head. A semi-through mounting groove is provided in the direction from the head to the tail of the second forceps head. A temperature probe is provided in the semi-through mounting groove. A wire is connected to the temperature probe. The temperature probe is provided in the semi-through mounting groove, and the wire extends outside the second forceps head. Thermal conductive glue is also filled in the semi-through mounting groove. A temperature display screen is provided on the handle. The tails of the first forceps head and the second forceps head are both hook-shaped.

[0006] The present invention transmits heat to the temperature probe better through the thermal conductive glue. The temperature probe detects the temperature of the tissue or blood vessel that needs to be operated between the surgical forceps, and then displays the temperature on the temperature display screen. At the same time, through the temperature control module, the detected temperature is compared with the set temperature, and the corresponding current output is adjusted. Then, the tails of the first forceps head and the second forceps head are both hook-shaped to hook, clamp, and dissect tissues to ensure that the temperature is maintained within a certain range during the entire operation and avoid the phenomenon of scorching of human tissues caused by too high temperature.

[0007] The thermal conductive adhesive of the present invention can fix the temperature probe in the second jaw, prevent the shaking of the temperature probe, and at the same time can seal between the wire and the temperature probe to achieve the function of waterproofing, and can also improve the thermal conductivity.

[0008] On the inner side of the first jaw, an upper toothed clamping electrocoagulation strip is formed along the length direction, on the second jaw, a lower toothed clamping electrocoagulation strip that cooperates with the upper toothed clamping electrocoagulation strip is formed along the length direction, and a coagulation-breaking strip is further provided on the inner side of the second jaw.

[0009] The present invention clamps and electrocoagulates tissues through the cooperation of the upper toothed clamping electrocoagulation strip of the first jaw and the lower toothed clamping electrocoagulation strip of the second jaw. Since the tails of both the first jaw and the second jaw are hook-shaped, tissues can be hooked, clamped, and dissected during the operation. The coagulation-breaking blade can effectively coagulate small blood vessels and tissues during the operation, enabling the surgical forceps to have multiple functions and eliminating the need to continuously replace the surgical forceps during the operation, thus shortening the operation time.

[0010] Preferably, there are two lower toothed clamping electrocoagulation strips, and the two lower toothed clamping electrocoagulation strips are arranged in parallel. The lower toothed clamping electrocoagulation strip includes several first tooth bodies and first tooth grooves that are alternately arranged in sequence. The end face of the first tooth body is a first arc surface that protrudes upward, and the bottom of the first tooth groove is a second arc surface that protrudes downward; the upper toothed clamping electrocoagulation strip includes several second tooth bodies and second tooth grooves that are alternately arranged in sequence. The second tooth body corresponds to the first tooth groove, and the second tooth groove corresponds to the first tooth body.

[0011] The present invention clamps and electrocoagulates tissues through the cooperation of the first tooth body and the second tooth groove, and through the cooperation of the first tooth groove and the second tooth body for biting. Through the design of the arc surface, the contact area with the tissue can be increased, facilitating clamping.

[0012] The end face of the first tooth body and the bottom of the first tooth groove can also be flat or can be a tip.

[0013] Preferably, the coagulation-breaking strip is arranged between the two lower toothed clamping electrocoagulation strips. The width of the coagulation-breaking strip gradually decreases from the side close to the second jaw to the side far from the second jaw. The first jaw is provided with a V-shaped card slot that cooperates with the coagulation-breaking strip.

[0014] The coagulation-breaking blade of the present invention gradually decreases from the side close to the second jaw to the side far from the second jaw, which can ensure the stability of the coagulation-breaking blade while ensuring its sharpness. The tissue is coagulated through the cooperation of the V-shaped card slot and the coagulation-breaking blade.

[0015] Preferably, the top surface of the coagulation-breaking strip is higher than the top surface of the upper toothed clamping electrocoagulation strip, and the top surface of the V-shaped card slot is higher than the inner surface of the first clamping head, so that the tissue can be coagulated and broken after clamping.

[0016] The handle includes a sleeve, a clamping head opening and closing mechanism, and a housing. The sleeve is connected to the housing. The multi-functional clamping head is arranged at the front end of the sleeve and extends out of the pipe orifice of the sleeve. The clamping head opening and closing mechanism controls the opening and closing action of the multi-functional clamping head.

[0017] The clamping head opening and closing mechanism includes a sliding rod, a sliding block, a front handle, and a rear handle. The sliding rod passes through the pipe hole of the sleeve. The sliding block is fixed on the outer side of the sliding rod and is slidably connected to the sleeve. The rear handle is rotatably connected to the starting end of the sliding rod. A second clamping head fixing plate is formed on one side of the second clamping head close to the sliding rod. The second clamping head fixing plate is provided with a first mounting hole and a second mounting hole in sequence from left to right. The height of the first mounting hole is higher than that of the second mounting hole. A third mounting hole is provided on the sliding rod and is matched with the first mounting hole. The sliding rod and the second clamping head fixing plate are rotatably connected through the third mounting hole and the first mounting hole;

[0018] Two first clamping head fixing plates are formed on one side of the first clamping head close to the sliding rod. The two first clamping head fixing plates are arranged on both sides of the second clamping head fixing plate. The first clamping head fixing plate is provided with a fourth mounting hole and a fifth mounting hole in sequence from left to right. The fourth mounting hole corresponds to the second mounting hole. The height of the fifth mounting hole is higher than that of the fourth mounting hole. The first clamping head fixing plate and the second clamping head fixing plate are rotatably connected through the fourth mounting hole and the second mounting hole. A fixing pin is provided on the fifth mounting hole. Extension plates are arranged on both sides of the sleeve at the position of the first clamping head fixing plate. The extension plates are connected to the fixing pin.

[0019] By pressing the rear handle, the sliding rod is controlled to retract inward, so that the first clamping head and the second clamping head are closed, and the functions of clamping, electrocoagulation and coagulation-breaking are completed. When the rear handle is released, the sliding rod extends outward, and the first clamping head and the second clamping head open.

[0020] The manufacturing method of the surgical forceps hook is as follows:

[0021] S1, opening holes: A semi-through mounting groove is opened in the direction from the head to the tail of the second clamping head through a sensor mounting device;

[0022] S2, flushing: With the head of the second clamping head facing downwards, the chips in the semi-through mounting groove are flushed through the sensor mounting device;

[0023] S3, drying: With the head of the second clamping head facing downwards, the second clamping head is dried through the sensor mounting device;

[0024] S4. Install a temperature probe. Place the temperature probe into the semi-through installation groove of the second jaw through a sensor installation device.

[0025] S5. Perform primary vibration potting. Pour 1 / 3 of the thermal conductive adhesive into the semi-through installation groove where the temperature probe is installed, and then perform vibration defoaming through the sensor installation device.

[0026] S6. Perform secondary vibration potting. Pour another 1 / 3 of the thermal conductive adhesive into the semi-through installation groove, and then perform vibration defoaming through the sensor installation device.

[0027] S7. Perform tertiary vibration potting. Pour the remaining 1 / 3 of the thermal conductive adhesive into the semi-through installation groove, and then perform vibration defoaming through the sensor installation device. Then wait for the thermal conductive adhesive to cure to complete the installation of the temperature probe.

[0028] S8. Assemble. Assemble the second jaw, the first insert head, and the handle.

[0029] In the present invention, the temperature probe is installed in the second jaw through an opening. The chips in the semi-through installation groove are flushed through flushing and drying, which is convenient for subsequent potting. Through three steps of potting, defoaming of the thermal conductive adhesive can be carried out, making the combination of the thermal conductive adhesive and the temperature probe closer, enhancing the thermal conductivity. Then, through assembly, the installation of the bipolar electrocoagulation dissection forceps hook is completed, so that the manufactured bipolar electrocoagulation dissection forceps hook has the function of detecting temperature.

[0030] Preferably, the sensor installation device includes a workbench, and the workbench is sequentially divided into a drilling area, a flushing area, a drying area, and a gluing area from left to right.

[0031] Preferably, the drilling area includes a second jaw fixing box, a drilling mechanism, and a fixing plate. The second jaw fixing box is arranged on the fixing plate, and the drilling mechanism is arranged above the second jaw fixing box.

[0032] The drilling mechanism includes an electric push rod, a drill bit, and a motor for driving the drill bit. This is a mature existing technology, so it will not be elaborated in this case.

[0033] In the present invention, the second jaw is arranged in the second jaw fixing box, making the head of the second jaw upward. Then, the second jaw fixing box is placed on the fixing plate, and then the drill bit of the drilling mechanism is pushed by the electric push rod to open an opening in the second jaw.

[0034] The second clamp head fixing box includes a box body and a cover plate. A partition is provided inside the box body, and the partition divides the box body into several second clamp head accommodation cavities. The second clamp head is stuck in the second clamp head accommodation cavity. An extrusion plate is provided on one side of the coagulation breaking strip in the second clamp head accommodation cavity. An extrusion card slot that cooperates with the coagulation breaking strip and the lower toothed clamping electrocoagulation strip is opened on the front surface of the extrusion plate, and a compression spring is provided on the back of the extrusion plate;

[0035] The cover plate includes a fixing plate. Through slots corresponding to the second clamp head accommodation cavities are opened on the fixing plate. First clamping strips, second clamping strips, and third clamping strips are arrayed on the through slots. The first clamping strip and the second clamping strip clamp the head of the second insert head. A clamping plate extends from the bottom of the third clamping strip, and the clamping plate clamps the side wall of the head of the second clamp head.

[0036] In the present invention, the tail of the second clamp head is placed downward into the second clamp head accommodation cavity. During the placement process, the extrusion plate moves outward under the extrusion force. When the lower toothed clamping electrocoagulation strip of the second clamp head touches the extrusion card slot, the compression spring drives the extrusion plate to rebound so that the lower toothed clamping electrocoagulation strip is stuck in the extrusion card slot, completing the fixation of the front and back sides of the second clamp. Then, the cover plate is covered so that the first clamping strip and the second clamping strip fix the head of the second clamp head, and the clamping plate fixes the left and right sides, thereby completing the fixation of multiple second clamp heads, which is convenient for later punching.

[0037] Preferably, a threaded hole is opened at the top of the box body. A through hole corresponding to the threaded hole is opened on the fixing plate. A threaded column passes through the through hole, and the bottom end of the threaded column is threadedly connected to the threaded hole. A nut is provided on the threaded column. The flushing area includes a water outlet box with an open top, a cleaning spray head. The water outlet box is provided at the bottom of the workbench. A water outlet groove is opened at the position of the workbench corresponding to the water outlet box. The cleaning spray head is provided at the bottom of the water outlet box. Positioning holes that cooperate with the threaded column are opened around the water outlet groove. A water outlet is opened on the side wall of the water outlet box.

[0038] The drying area 84 includes a fixing frame 841. A drying groove 842 of the same size as the water outlet groove 833 is opened on the workbench. The fixing frame 841 is provided around the drying groove 842. Drying fixing holes of the same size as the positioning holes are opened at the top of the fixing frame 841. A drying box 843 is provided at the bottom of the drying groove 842. Heating sheets are provided inside the drying box 843. Heat dissipation holes 845 are opened on the fixing frame 841.

[0039] In the present invention, the cover body and the box body are fixed by the threaded connection of the threaded post and the threaded hole, and then by the threaded connection of the nut and the threaded post. After drilling, only the second jaw fixing box needs to be fixed downward, and the threaded post is fixed in the positioning hole in the flushing area to fix the second jaw after drilling. Then, the second jaw and the semi-through installation groove of the second jaw can be flushed through the cleaning nozzle. The impurities and water after flushing are discharged through the water outlet. Then, the second jaw fixing box is moved to the drying area and fixed in the drying fixing hole, and then heated. The hot air after heating is discharged through the heat dissipation holes to complete the drying step. Then, the second jaw fixing box is moved upward to the material fixing frame in the gluing area to perform glue filling. In the whole process, only the second jaw needs to be fixed in the second jaw fixing box and does not need to be taken out later, and steps such as flushing, drying, and gluing can be carried out, improving the work efficiency.

[0040] Preferably, the gluing area includes a support frame, a gluing electric push rod, a gluing fixed plate, a dispensing head, a material fixing frame, and an up-and-down vibration mechanism. The support frame is arranged on the side of the workbench. The gluing electric push rod is arranged at the inner top of the support frame. The gluing fixed plate is arranged at the push rod end of the gluing electric push rod. The dispensing head is arranged at the bottom of the gluing fixed plate. The material fixing frame is arranged below the dispensing head. The up-and-down vibration mechanism is arranged at the bottom of the material fixing frame. There are multiple dispensing heads, which can perform one-time glue filling on the second jaw in the second jaw fixing box.

[0041] In the present invention, the second jaw fixing box is fixed upward by the material fixing frame, the temperature probe is placed into the semi-through installation groove, and then the gluing electric push rod moves downward, and the dispensing head discharges the heat-conducting glue to fill the temperature probe, thus completing the glue filling step. Multiple second jaws can be glued at one time, improving the work efficiency.

[0042] The up-and-down vibration mechanism includes a base. A crank is rotatably arranged between the two bases. A first connecting rod is arranged between the two cranks. The bottom end of the first connecting rod is rotatably connected to the crank. The top end of the first connecting rod is rotatably connected to a connecting block. A hollow slide rod is arranged at the top of the connecting block. A fixed block is arranged on the outer side wall of the slide rod. A chute for the slide rod to slide is opened on the fixed block. The top of the fixed block is fixedly connected to a material placing frame. A second connecting rod is arranged inside the slide rod. The top end of the second connecting rod is fixedly connected to the material placing frame. An anti-detachment block is fixedly connected to the bottom end of the slide rod. A first spring is sleeved on the outer side wall of the second connecting rod. The first spring is fixedly connected to the slide rod. Second springs are also arranged on both sides of the material placing frame. One end of the second spring is fixedly connected to the material placing frame, and the other end is fixedly connected to the base.

[0043] In the present invention, the crank rotates, driving the movement of the first connecting rod, which in turn drives the connecting block to impact the anti - detachment block, driving the sliding rod to move within the sliding groove, thereby jacking up the material placement frame. Then, under the elastic force of the first spring and the second spring, the material placement frame moves downward, forming a certain height difference, causing the material placement frame to vibrate, thereby achieving vibration defoaming.

[0044] In summary, the beneficial effects of the present invention are as follows:

[0045] 1. In the present invention, the heat - conducting adhesive transmits heat to the temperature probe better. The temperature probe detects the temperature of the tissue or blood vessel that needs to be operated on between the surgical forceps, and then displays the temperature on the temperature display screen. At the same time, through the temperature control module, the detected temperature is compared with the set temperature, and the corresponding current output is adjusted. Then, the tails of the first forceps head and the second forceps head are both hook - shaped to hook, clamp, and peel the tissue, ensuring that the temperature remains within a certain range during the entire surgical process and avoiding the phenomenon of burning human tissue due to excessive temperature.

[0046] 2. The heat - conducting adhesive of the present invention can fix the temperature probe in the second forceps head, prevent the shaking of the temperature probe, and at the same time can seal between the wire and the temperature probe to achieve the waterproof effect, and can also improve the heat - conducting performance.

[0047] 3. In the present invention, the tissue is clamped and electrocoagulated through the cooperation of the upper toothed clamping of the electrocoagulation strip by the first forceps head and the lower toothed clamping of the electrocoagulation strip by the second forceps head. The tails of the first forceps head and the second forceps head are both hook - shaped, and during the surgical process, the tissue can be hooked, clamped, and peeled. The coagulation - cutting blade can effectively coagulate and cut small blood vessels and tissue during the surgical process, enabling the surgical forceps to have multiple functions, and there is no need to continuously replace the surgical forceps during the surgical process, shortening the surgical time.

[0048] 4. In the present invention, the temperature probe is installed in the second forceps head through an opening. The chips in the semi - through installation groove are washed through flushing and drying, which is convenient for later glue filling. Through three steps of glue filling, defoaming of the heat - conducting adhesive can be achieved, making the combination of the heat - conducting adhesive and the temperature probe closer, strengthening the heat - conducting performance. Then, through assembly, the installation of the bipolar electrocoagulation and cutting surgical forceps hook is completed, so that the manufactured bipolar electrocoagulation and cutting surgical forceps hook has the function of detecting temperature.

[0049] The tail of the second clamp head is placed downward into the accommodating cavity of the second clamp head. During the placement process, the extrusion plate moves outward under the extrusion force. When the lower toothed clamping electrocoagulation strip of the second clamp head touches the extrusion card slot, the compression spring drives the extrusion plate to rebound, causing the lower toothed clamping electrocoagulation strip to be stuck in the extrusion card slot, completing the fixation on both the front and rear sides of the second clamp. Then, the cover plate is covered so that the first clamping strip and the second clamping strip fix the head of the second clamp head, and the clamping plate fixes the left and right sides, thereby completing the fixation of multiple second clamp heads, facilitating subsequent drilling.

[0050] 5. In the present invention, through the threaded connection between the threaded column and the threaded hole, and then through the threaded connection between the nut and the threaded column, the fixation of the cover body and the box body is completed. After drilling, only the second clamp head fixing box needs to be turned downward, and the threaded column is fixed in the positioning hole in the flushing area to fix the drilled second clamp head. Then, the second clamp head and the semi-through installation groove of the second clamp head can be flushed through the cleaning nozzle. The impurities and water after flushing are discharged through the water outlet. Then, the second clamp head fixing box is moved to the drying area and fixed in the drying fixing hole, and then heated. The hot air after heating is discharged through the heat dissipation holes, and the drying step can be completed. Then, the second clamp head fixing box is moved upward to the material fixing frame in the gluing area to perform glue filling. In the whole process, only the second clamp head needs to be fixed in the second clamp head fixing box, and there is no need to take it out later, and steps such as flushing, drying, and gluing can be carried out, improving the work efficiency.

[0051] In the present invention, the crank rotates, thereby driving the movement of the first connecting rod, which in turn drives the sliding rod to impact the anti-detachment block, thereby jacking up the material placement frame. Then, under the elastic force of the first spring and the second spring, the material placement frame moves downward, thereby forming a certain height difference, causing the material placement frame to vibrate, and thus performing vibration defoaming.

[0085] Working principle:

[0086] As Figures 1-17As shown, the tail of the second jaw 32 is placed downward into the second jaw receiving cavity 864. During the placement process, the pressing plate 865 moves outward under the extrusion force. When the lower toothed clamping electrocoagulation strip of the second jaw 32 touches the extrusion card slot 866, the compression spring 867 drives the pressing plate 865 to rebound, causing the lower toothed clamping electrocoagulation strip to be stuck in the extrusion card slot, completing the fixation of the front and back sides of the second jaw. After that, the cover plate 862 is covered so that the first clamping strip 8681 and the second clamping strip 8682 fix the head of the second jaw, and the clamping plate 8684 fixes the left and right sides, thus completing the fixation of multiple second jaws. Then, the drilling head of the drilling mechanism is pushed by the electric push rod to drill holes in the second jaw. After drilling, the second jaw fixing box 86 is lowered, and the threaded column 8602 is fixed in the positioning hole 8331 of the flushing area 83 to fix the drilled second jaw 32. Then, the second jaw can be flushed through the cleaning nozzle 832 in the semi-through installation groove 326 of the second jaw. The impurities and water after flushing are discharged through the water outlet 830. Then, the second jaw fixing box is moved to the drying area 84 and fixed in the drying fixing hole 844, and then heated. The hot air after heating is discharged through the heat dissipation holes, completing the drying step. Then, the second jaw fixing box is moved upward into the material fixing frame in the gluing area. Then, the temperature probe 6 is placed into the semi-through installation groove 326. Then, the gluing electric push rod moves downward, and the dispensing head discharges the thermal conductive glue to perform the first potting on the temperature probe. Then, the crank 872 rotates, driving the movement of the first connecting rod 873, which drives the connecting block 874 to impact the anti-detachment block 870, thus lifting the material placement frame upward. Then, under the elastic force of the first spring and the second spring, the material placement frame moves downward, creating a certain height difference, causing the material placement frame to vibrate, thus performing the first vibration defoaming. Then, the first potting and the first vibration defoaming are repeated, performing the second potting, the second vibration defoaming, the third potting, and the third vibration defoaming. Then, the second jaw, the first jaw, and the handle are assembled.

[0087] When the assembled bipolar electrocoagulation dissection forceps hook is in use, heat is better transmitted to the temperature probe through the thermal conductive adhesive. The temperature probe detects the temperature of the tissue or blood vessel that needs to be operated on between the forceps, and then the temperature is displayed on the temperature display screen. At the same time, through the temperature control module (how the temperature control module controls the temperature sensor is prior art and will not be elaborated in this case), the detected temperature is compared with the set temperature, and the corresponding current output is adjusted. Then, the tails of the first forceps head (31) and the second forceps head (32) are both hook-shaped to hook, clamp, and dissect the tissue, so as to ensure that the temperature is maintained within a certain range during the whole operation, avoiding the phenomenon of burning human tissue due to too high temperature. Then, the tissue is hooked, clamped, and dissected through the hooks of the first forceps head 31 and the second forceps head 32. The tissue is clamped and electrocoagulated through the cooperation of the upper toothed clamping electrocoagulation strip 311 of the first forceps head and the lower toothed clamping electrocoagulation strip 321 of the second forceps head. The small blood vessels and tissue are effectively coagulated and transected by the coagulation and transection blade 33 during the operation, so that the forceps has multiple functions, and there is no need to continuously replace the forceps during the operation, shortening the operation time.
