Description

Technical Field

[0001] This utility model relates to the technical field of surgical electrode forming molds, and in particular to a mold for processing surgical electrodes. Background Technology

[0002] The plasma ablation bipolar electrode is installed parallel to the endoscope sheath. Medical staff push the electrode back and forth, and the energy generator delivers high-frequency energy to the electrode cutting ring on the front end of the electrode through the electrode connecting wire. The electrode cutting ring contacts the target tissue and quickly vaporizes and separates the tissue, thus removing the lesion.

[0003] In existing technologies, plasma ablation bipolar electrodes, in order to accommodate the installation and use of endoscopes, require a pre-reserved channel for the endoscope to facilitate observation of the cutting location. Simultaneously, to prevent the electrode cutting ring from getting caught on the endoscope head during operation and to ensure smooth cutting, a partial bending process is often required. Currently, this bending is typically done manually, leading to low production efficiency and significant processing errors, resulting in lower precision. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of low electrode production efficiency in the prior art and provides a surgical electrode forming mold that is conducive to improving electrode production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mold for processing surgical electrodes, comprising:

[0007] upper mold;

[0008] The lower mold is connected to the upper mold in a sliding manner. When the mold is closed, the upper mold and the lower mold together form a cavity.

[0009] The front-end bending assembly and the left and right extrusion assemblies are both fixedly connected to the front end of the cavity, and the front-end bending assembly is located on the side of the left and right extrusion assemblies.

[0010] The rear bending assembly is fixedly connected to the rear end of the cavity.

[0011] The dual-rod bipolar electrode is placed on the lower mold and positioned within the cavity. During mold closing, the operator controls the driver via the control system to press down the upper mold. The front and rear bending components bend the front and rear ends of the dual-rod bipolar electrode at a certain angle, respectively, replacing manual processing and improving electrode production efficiency. The front bending component bends the front end of the dual-rod bipolar electrode to provide a channel for the endoscope, facilitating observation of the cutting position after the endoscope passes through, while preventing the electrode cutting ring from getting caught on the endoscope head and hindering operation. The rear bending component bends the rear end of the dual-rod bipolar electrode to facilitate its use with the endoscope. The left and right extrusion components extrude the rods of the dual-rod bipolar electrode, making its internal structure more stable and robust.

[0012] Preferably, the upper mold includes an upper base plate and an upper template. One side of the upper template is detachably connected to the center of the upper base plate. The lower mold includes a lower base plate, a lower template 1, and two lower template 2s. The upper base plate and the lower base plate are slidably connected vertically. The top front and rear ends of the lower template 1 are fixedly connected to the two lower template 2s respectively. The bottom of the lower template 1 is elastically connected to the lower base plate, forming a floating gap. The cavity includes a cavity 1 and a cavity 2. The cavity 1 is formed by the front end of one lower template 2 on the opposite side of the upper template. The cavity 2 is formed by the rear end of the other lower template 2 on the opposite side of the upper template. The left and right extrusion components and the front bending component are distributed in the cavity 1 along the front-rear direction. The rear bending component is located in the cavity 2. Since only the two ends of the double-rod bipolar electrodes are bent, the lower template 2 is divided into two parts, which facilitates installation and disassembly and saves materials.

[0013] Preferably, the front-end bending assembly includes a front-end bending die core with a rectangular cross-section. The bottom of the front-end bending die core is fixedly connected to the lower base plate. The top of the front-end bending die core passes through the lower template and is located inside the lower template. A forming block extends upward from the center of the top of the front-end bending die core, and its edge forms a stepped bending forming surface. The bottom of the forming block is fixedly connected to the front-end bending die core. The top of the forming block passes through the lower template and protrudes from the surface of the lower template. Guide slopes are provided on the left and right sides of the top and the left and right sides of the rear of the forming block. The front and rear ends of the upper template are respectively provided with a connected forming groove 1 and a forming groove 2. The forming groove 1 and the forming groove 2 are located inside the cavity 1 and the cavity 2, respectively. A front-end bending head is provided inside the upper template. One end of the front-end bending head is fixedly connected to the upper template. The other end of the front-end bending head is located inside the forming groove 1 and corresponds to and matches the bending forming surface 1. The other end of the front-end bending head is provided with an insertion hole that matches the forming block. Initially, the forming block is located between the two electrode rods of the dual-rod bipolar electrode. Because the bottom of the lower template one is elastically connected to the lower base plate, forming a floating gap, when the upper die presses down, it pushes the lower template one and lower template two downwards simultaneously. At the same time, the forming block gradually inserts into the insertion hole, and the bending forming surface one gradually protrudes from the lower template two, working together with the front punching head to bend the two electrode rods of the dual-rod bipolar electrode in one bending operation. This improves both production efficiency and bending accuracy. The shape of the bending forming surface one can be set according to actual bending requirements. The guide slope at the top of the forming block provides good guidance when the forming block is inserted into the insertion hole. The guide slope at the rear of the forming block increases the distance between the two electrode rods of the dual-rod bipolar electrode, matching the electrode cutting ring.

[0014] Preferably, the left and right sides of the first bending forming surface are symmetrically distributed around the forming block. The front end of the left side of the first bending forming surface sinks down and connects with the front end of the right side to form a C-shaped plane. The front end of the left side of the first bending forming surface rises from the sinking part and gradually tilts downward to connect with the rear end, with the connection point transitioning evenly through an arc surface. The rear end of the first bending forming surface is a horizontal plane. Since the electrode is a bipolar electrode, the internal rod of the electrode rod needs to form two parallel rods at the end, which are respectively connected to two electrode cutting rings. Therefore, during forming, the sinking position of the front end of the first bending forming surface matches this part, so that this part is limited to this location and the front bending head. Before the two rods are formed in this part, the electrode rod is bent by the rising part and the rear end of the first bending forming surface to reserve a channel for the endoscope, so that the endoscope can pass through and observe the cutting position. At the same time, it avoids the electrode cutting ring from getting caught on the head of the endoscope and being unable to work.

[0015] Preferably, the left and right extrusion assembly includes an extrusion die core and two extrusion blocks symmetrically distributed around the extrusion die core. The extrusion die core is located inside the cavity. One end of the extrusion die core is fixedly connected to the lower base plate, and a protrusion is fixed at the center of the other end of the extrusion die core. Two extrusion grooves are arranged parallel to each other in the front-back direction on both sides of the protrusion, forming an extrusion protrusion between the two extrusion grooves. Two T-shaped sliding grooves are opened on the lower template at the front end of the lower template, which respectively match the two extrusion blocks. The bottom of the extrusion block matches the T-shaped sliding groove and slides on the lower template in the left-right direction. Two clearance grooves are provided on the upper template, which respectively match the top of the two extrusion blocks. One end of the extrusion block is close to the protrusion, and the other end of the extrusion block is away from the protrusion. A V-shaped pressure head corresponding to the extrusion protrusion is fixed at the top of the end of the extrusion block close to the protrusion. In the initial state, the protrusion is located between the two electrode rods on the left and right sides, with the electrode rods on top of the protrusion. Since the bottom of the lower template one is elastically connected to the lower base plate and forms a floating gap, when the upper mold presses down, it pushes the lower template one and the lower template two to move down synchronously. At the same time, the extrusion groove one gradually moves up and corresponds to the two rods that are parallel to each other and connected to the two electrode cutting rings respectively, so that the extrusion protrusion is located between the two rods. When the upper mold presses down, the extrusion blocks one on the left and right sides move closer to each other at the same time. Through the interaction between the corresponding V-shaped pressure head and the corresponding extrusion protrusion, the center of the shell covering the outside of the two rods is squeezed between the two rods, so that the shell tightly wraps and presses the two rods, which helps to improve the stability and firmness of the electrode structure.

[0016] Preferably, the top of the end of the extrusion block 1 away from the protrusion is provided with an inclined guide surface. Two driving blocks are fixed in the clearance groove, each corresponding one-to-one with one of the two extrusion blocks 1. One end of each driving block is fixedly connected to the bottom of the clearance groove, and the other end of each driving block is located within the opening of the clearance groove and is provided with a driving surface that matches the corresponding guide surface and is arranged at an inclination. Under the driving action of the driving surface on the corresponding driving block matching the guide surface, the extrusion block 1 elastically slides to the lower mold plate 2 in the left-right direction. When the upper mold presses down, the driving block acts on the guide surface through the inclined driving surface to overcome the elastic action and gradually push the corresponding extrusion block 1 towards the cavity direction to slide. This structure is simple and helps save costs. Conversely, when the upper mold leaves the lower mold, the driving block resets under elastic action.

[0017] Preferably, the rear-end bending assembly includes a rear-end bending die core with a rectangular cross-section. The bottom of the rear-end bending die core is fixedly connected to the lower template one. A bending groove is provided on the lower template two at the rear end of the lower template one. The bending groove is located at the rear end of the lower template two. The top of the rear-end bending die core is a bending forming surface two. The top of the rear-end bending die core passes through the lower template two and is located in the bending groove. A rear-end bending head is provided in the upper template. One end of the rear-end bending head is fixedly connected to the upper template. The other end of the rear-end bending head is located in the forming groove two and corresponds to and matches the bending forming surface two. To facilitate the use of the endoscope, the rear end of the electrode needs to be bent using the rear bending assembly. In the initial state, the two electrode rods are placed parallel to each other on the surface of the lower template. When the upper die is pressed down, the rear bending head presses down, causing the two electrode rods to bend along the bending forming surface two in one step, thereby improving production efficiency and bending accuracy. The shape of the bending forming surface two can be set according to the actual bending requirements. In this invention, the two ends of the bending forming surface two are parallel planes, and the middle is an inclined surface that facilitates bending.

[0018] Preferably, a rectangular extrusion block II protrudes from the bending forming surface II. The extrusion block II has two extrusion grooves II arranged parallel to each other in the front-to-back direction and both being arc-shaped. The other end of the rear punching head has a stamping block corresponding to the extrusion block II. The stamping block has two stamping grooves, each corresponding to one of the extrusion grooves II. The two electrode rods are located within their respective extrusion grooves II. When the upper die presses down, the mutual extrusion of the stamping block II and the extrusion block II, along with the interaction between the extrusion grooves II and the corresponding stamping grooves, causes the electrode rods to be compressed vertically, resulting in outwardly protruding lugs on both the front and rear sides. This improves the robustness and stability of the internal structure of the electrode rods.

[0019] Preferably, the upper base plate is provided with a punch with the same height as the thickness of the upper template. The punch is located at the rear end of the upper template. One end of the punch is fixedly connected to the upper base plate, and the other end of the punch is provided with a through hole and two upper limit slots that correspond to two stamping grooves and are on the same straight line. The stamping grooves are located at the front end of the upper limit slots, and the through hole is located at the rear end of the upper limit slots. A riveting knife is provided in the through hole. One end of the riveting knife is fixedly connected to the upper base plate, and the other end of the riveting knife passes through the through hole and corresponds to the upper limit slot. The other end of the riveting knife is provided with a V-shaped cutting head, and the bend of the V-shaped cutting head forms a cutting edge. The base plate is provided with a punch seat corresponding to the punch. The height of the punch seat is equal to the sum of the thicknesses of the lower template 1 and the lower template 2. The punch seat is slidably connected to the lower template 2 at the rear end of the lower template 1. One end of the punch seat is fixedly connected to the lower base plate. The other end of the punch seat is provided with a through hole 2 corresponding to the through hole 1 and two lower limit grooves respectively corresponding to the two upper limit grooves 1 and 2. A riveting knife 2 is provided in the through hole 2. One end of the riveting knife 2 is fixedly connected to the lower base plate. The other end of the riveting knife 2 passes through the through hole 2 and corresponds to the lower limit groove. The other end of the riveting knife 2 is provided with a trapezoidal cutter head. The front and rear ends of the trapezoidal cutter head form parallel and protruding cutting edges 2. In the initial state, the ends of the two electrode rods are placed on the trapezoidal cutter head after passing through the two lower limit grooves. When the upper mold presses down, the first riveting cutter cuts the top of the two electrode rods through the first cutting edge of the V-shaped cutter head, while the second riveting cutter cuts the bottom of the two electrode rods through the second cutting edges of the trapezoidal cutter head. This results in a cut opening at the top of the electrode rod and two cut openings at the bottom of the electrode rod, which is used to rivet and press the internal electrode wire tightly and prevent the electrode wire from being pulled out from the cutting ring.

[0020] Preferably, a limiting block is provided on the lower template two at the front end of the lower template one. The bottom of the limiting block is fixedly connected to the front end of the lower template two, and the top of the limiting block protrudes from the surface of the lower template two. The limiting block is located inside the cavity one, and the left and right extrusion components are located between the limiting block and the front bending component. The limiting block facilitates the electrode to contact the template through its end, which facilitates the initial positioning of the electrode and improves the accuracy of the positions requiring bending and extrusion processing.

[0021] Preferably, each of the lower templates at both ends of the lower template one is provided with two sets of positioning components. These positioning components are located between the front bending component and the rear bending component, and are symmetrically distributed along the front-rear direction. Each positioning component includes two left-right corresponding limiting vertical plates one, two left-right corresponding limiting vertical plates two, and an insert block. The limiting vertical plates one, two limiting vertical plates two, and the insert block are all located within the forming cavity. The insert block is located between the two limiting vertical plates one, and the limiting vertical plate two is located between the limiting vertical plates one and the insert block. The limiting vertical plates one on one set of positioning components are closer to the other set of positioning components, and the insert block on that set is farther from the other set of positioning components. The limiting vertical plates one... One end of the upper template and one end of the limiting vertical plate are both fixedly connected to the lower template. The top of the limiting vertical plate and the top of the limiting vertical plate protrude from the surface of the lower template. The height of the limiting vertical plate is greater than the height of the limiting vertical plate. Both the limiting vertical plate and the limiting vertical plate are provided with arc-shaped surfaces on their side walls. The front and rear ends of the upper template are provided with two pressing rods that correspond one-to-one with the limiting vertical plates on the two sets of positioning components. One end of the pressing rod is fixedly connected to the upper template. The other end of the pressing rod is matched with the two limiting vertical plates and is provided with two arc-shaped pressing grooves distributed in the left and right direction. The two pressing grooves are respectively aligned vertically with the arc-shaped surfaces on the two limiting vertical plates. The two sets of positioning components provide good positioning for the electrodes when bending the front and rear bending components, respectively, thereby improving the bending accuracy. The insert block is located between the two electrode rods, and the two limiting vertical plates 1 respectively match and contact the left and right sides of the insert block on the electrode, thereby positioning the electrode and preventing deformation of the insert block. The two limiting vertical plates 2 on the two sets of positioning components correspond one-to-one with the lower pressure rods on the upper template, positioning the electrode and pressing the clamping rings on the corresponding electrode rods at both ends of the insert block through the corresponding clamping grooves, thereby improving the fit between the insert block and the electrode.

[0022] The beneficial effects of this utility model are: by punching the front and rear ends of the bipolar electrode at a certain angle using a mold, manual processing is replaced, thereby improving electrode production efficiency; it facilitates installation and disassembly while saving materials; it improves bending accuracy while increasing production efficiency; it enhances the stability and robustness of the electrode structure; and its simple structure helps save costs.

[0050] like Figure 6 and Figure 9As shown, a limiting block 52 is provided on the lower template 2 10 at the front end of the lower template 1 9. The bottom of the limiting block 52 is fixedly connected to the front end of the lower template 2 10, and the top of the limiting block 52 protrudes from the surface of the lower template 2 10.

[0051] like Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, two sets of positioning components 53 are provided on the lower template 2 10 at both ends of the lower template 1 9. The positioning components 53 are located between the front bending component 3 and the rear bending component 5. The two sets of positioning components 53 are symmetrically distributed in the front-rear direction. The positioning components 53 include two left and right corresponding limiting vertical plates 1 54, two left and right corresponding limiting vertical plates 2 55, and insert blocks 56. The limiting vertical plates 1 54, the limiting vertical plates 2 55, and the insert blocks 56 are all located in the forming cavity.

The other end of the pressing rod 58 is matched with the two limiting vertical plates 2 55 and is provided with two arc-shaped pressing grooves 59 distributed in the left and right direction. The two pressing grooves 59 are respectively vertically aligned with the arc-shaped surfaces 57 on the two limiting vertical plates 2 55.

[0052] Combination Figures 11-14In the first embodiment of this utility model, a dual-rod bipolar electrode is placed on the lower mold 2 and positioned within the cavity, and is positioned by a limiting block 52 and a positioning component 53. Initially, the forming block 15 and the protrusion 23 are both located between the upper template 761 of the two electrode rods of the dual-rod bipolar electrode. The upper template 761 of the electrode rods is located on top of the protrusion 23. When the mold is closed, the operator controls the driver through the control system to press down the upper mold 1. Because the bottom of the lower template 1 9 is elastically connected to the lower base plate 8 and forms a floating gap 11, when the upper mold 1 is pressed down, the lower template 1 9 and the lower template 2 10 press down synchronously. As the forming block 15 moves, it is gradually inserted into the insertion hole 20, and the bending forming surface 16 gradually protrudes from the lower template 2 10. Together with the front punching head 19, it bends the upper template 7 of the two electrode rods of the double rod bipolar electrode in one step, thereby improving production efficiency and bending accuracy. The shape of the bending forming surface 16 can be set according to the actual bending requirements. The guide slope 60 at the rear end of the forming block 15 increases the distance between the upper template 7 of the two electrode rods of the double rod bipolar electrode, matching and adapting to the upper template 7 of the electrode cutting ring 762.

[0053] Since the electrode is a bipolar electrode, the upper template 763 of the upper template 7 inside the upper template 761 of the electrode rod needs to form two parallel upper templates 763 of the upper template 7 at the end, which are respectively connected to the upper templates 762 of the two electrode cutting rings. Therefore, during the forming process, the lower position of the front end of the bending forming surface 16 matches this part, so that this part is limited to this part and the front punching head 19. Before the two upper templates 763 of the upper template 7 are formed in this part, the upper template 761 of the electrode rod is bent by the rising part of the bending forming surface 16 and the rear end, so as to reserve a channel for the endoscope, so that the endoscope can pass through and observe the cutting position. At the same time, it avoids the upper template 762 of the electrode cutting ring being hung on the head of the endoscope and unable to work.

[0054] In the second embodiment, during the downward pressing of the upper die 1, the extrusion groove 24 gradually moves upward and aligns with the two parallel rod upper templates 763 connected to the upper templates 762 and 7 of the two electrode cutting rings, respectively. This causes the extrusion protrusion 25 to be located between the upper and lower rod upper templates 763. Simultaneously with the downward pressing of the upper die 1, the driving block 30 acts on the guide surface 29 through the inclined driving surface 31 to overcome the elastic effect and gradually push the corresponding extrusion block 22 towards the cavity direction. The sliding motion causes the left and right extrusion blocks 22 to move closer together simultaneously. Through the interaction of the corresponding V-shaped pressure heads 28 and the corresponding extrusion protrusions 25, the upper shell template 764, which covers the outer side of the upper template 763 of the two rods, is pressed between the upper shell template 764 and the upper shell template 763. This tightly wraps and presses the upper shell template 764 and the upper shell template 763 of the two rods together, improving the stability and robustness of the electrode structure. Conversely, when the upper mold 1 moves away from the lower mold 2, the drive block 30 resets under elastic action.

[0055] In Example 3, to facilitate the use of the endoscope, the rear end of the electrode needs to be bent by the rear bending assembly 5. In the initial state, the upper template 7 of the two electrode rods is placed parallel to the surface of the lower template 10. When the upper mold 1 is pressed down, the rear bending head 35 is pressed down, causing the upper template 7 of the two electrode rods to bend along the bending forming surface 34 in one step, thereby improving production efficiency and bending accuracy. The shape of the bending forming surface 34 can be set according to the actual bending requirements. In this utility model, the two ends of the bending forming surface 34 are parallel planes, and the middle is an inclined surface that facilitates bending.

[0056] In Example 4, the upper template 761 of the two electrode rods is located in the corresponding extrusion groove 37. When the upper mold 1 is pressed down, the mutual extrusion of the stamping block 38 and the extrusion block 36, under the interaction of the extrusion groove 37 and the corresponding stamping groove 39, causes the upper template 761 of the electrode rod to be extruded in the vertical direction, and both the front and rear sides are extruded into the ear plate upper template 765 upper template 7, which helps to improve the firmness and stability of the internal structure of the upper template 761 of the electrode rod.

[0057] In the fifth embodiment, in the initial state, the ends of the upper templates 761 of the two electrode rods are placed on the trapezoidal cutter head 50 after passing through the two lower limit grooves 48 respectively. When the upper mold 1 is pressed down, the first riveting cutter 43 cuts grooves on the top of the upper templates 761 of the two electrode rods through the first cutting edge 45 on the V-shaped cutter head 44. At the same time, the second riveting cutter 49 cuts grooves on the bottom of the upper templates 761 of the two electrode rods through the second cutting edge 51 at both ends of the trapezoidal cutter head 50. This results in a cut-out upper template 766 formed on the top of the upper templates 761 of the electrode rods, and two cut-out upper templates 766 formed on the bottom of the upper templates 761 of the electrode rods. This is to rivet and press the internal electrode wires tightly and prevent the electrode wires from being pulled out from the upper template 762 of the electrode cutting ring.

[0058] In Example 6, during the above operation, the two sets of positioning components 53 provide a good positioning effect for the electrode when bending the front bending component 3 and the rear bending component 5, respectively, thereby improving the bending accuracy. The insert block is located between the upper template 7 of the two electrode rods 761 and the upper template 7. The two limiting vertical plates 54 make matching contact with the left and right sides of the upper template 768 of the electrode insert block, thereby positioning the electrode and preventing deformation of the upper template 768 of the insert block. The two limiting vertical plates 55 on the two sets of positioning components 53 correspond one-to-one with the lower pressing rods 58 on the upper template 7. While positioning the electrode, the corresponding pressing grooves 59 press the upper template 768 of the insert block to the upper template 7 of the corresponding electrode rod 761, thereby improving the fit between the upper template 768 of the insert block and the electrode.
