Description

Technical Field

[0001] The present invention relates to the technical field of electrocoagulation forceps, in particular to a surgical instrument and a use method thereof. Background Art

[0002] Electrocoagulation forceps are often used during surgery. High-frequency electrical energy is transmitted to both ends of the forceps. The current causes local heating of the tissue, thereby thermally coagulating the tissue and quickly cutting the tissue. The tip of the forceps is specially designed to concentrate the current and accelerate the cutting and hemostasis effects. It can accurately control the depth and shape of the cutting, leaving almost no scars, and is highly safe and precise.

[0003] However, under high temperatures, tissue proteins will coagulate and adhere to the jaws, making it difficult to open the jaws. Forced separation may tear off the coagulated tissue, causing secondary bleeding. The existing solution is to use saline solution to cool and soften the tissue, but it is difficult for doctors to spare time to take out saline solution during micro-manipulation. At the same time, high temperatures will cause the tissue to produce a certain amount of salt mist, which will affect the doctor's vision. Summary of the Invention

[0011] Preferably, the transfer mechanism includes a connector, one end of which is fixedly connected to the main body, and one end of which is away from the main body and fits in with the main pipe, wherein the interior of the connector is slidably fitted with the central push rod.

In addition, both ends of the trapezoidal curved block are curved surfaces with the same shape, but one end is thicker and the other end is thinner.

[0014] Preferably, positioning components are symmetrically provided on both sides of the main body; The positioning assembly includes an end rail, the bottom of the inner cavity of the end rail is fixedly connected to a No. 2 elastic telescopic rod, the top of the No. 2 elastic telescopic rod is fixedly connected to a top block, wherein the number of No. 2 elastic telescopic rods and the top blocks is several, and each of the top blocks is in contact with and fits with each other.

[0016] A method for using a surgical instrument comprises the following steps: Step 1: Turn the handle and extend the center push rod outward, so that the upper and lower inclined surfaces of the inclined block connected to the other end of the center push rod will squeeze the No. 1 and No. 2 clamp heads respectively. At this time, the two inserted heads will be in an expanded state, otherwise they will be in a clamped state; Step 2: The operator rotates the handle clockwise, and the pull rod fixed to the top of the handle is pulled and moves toward the main body. The pull rod creates a gap between the sealing plate and the trapezoidal platform, and the physiological saline stored in the U-shaped platform is discharged from the gap to clean the part where the jaws and tissue are adhered. Step 3: The operator turns the adjustment handle clockwise, so that the deflection rod connected to it through the same through-axis will move downward, and the other end of the deflection rod is connected to the column, so the column will pass downward from the bottom of the shift block and squeeze any top block at its bottom. At the same time, the No. 2 elastic telescopic rod connected to the bottom of the top block will shrink to limit the shift block and the handle.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The curved rails enhance the deflection stability of the first and second jaws and provide a position limit to prevent them from deflecting or deflecting at different angles during compression by the bevel block. Furthermore, the operator can adjust the deflection angles of the first and second jaws simply by pulling the handle inward. Releasing the handle automatically returns the first and second jaws to their original positions.

[0018] 2. As the occluding plate moves inward, a gap will be created between the occluding plate and the trapezoidal platform, so that the physiological saline stored inside the U-shaped platform will be discharged outward from the gap and the part where the jaws and tissues are adhered will be cleaned, thus avoiding heavy bleeding caused by forced tearing.

[0019] 3. The inner cavity of the U-shaped table is divided into two cavities by a partition. One cavity is used to store physiological saline, and the other cavity is connected to the external trachea. When burns occur between the jaws and tissue and a certain amount of smoke is generated, the trachea will absorb the smoke, thereby preventing the accumulation of smoke and affecting the operator's subsequent hemostasis or ligation.

[0020] 4. The thicker part of the trapezoidal curved block is larger than the slot of the No. 2 inner groove, while the thinner part of the trapezoidal curved block is smaller than the slot of the No. 2 inner groove. However, when the trapezoidal curved block pops out, the thicker part is close to the No. 2 inner groove. Therefore, the trapezoidal curved block can no longer pass through the No. 2 inner groove to return to the No. 2 plug-in block, thereby achieving self-locking of the inner arc plate and locking of the main body and the connector.

[0021] 5. The column passes downward from the bottom of the shift block and squeezes any top block at the bottom. At the same time, the second elastic telescopic rod connected to the bottom of the top block will shrink, thereby limiting the shift block and the handle, preventing the operator from getting tired from constantly pressing the handle.

[0036] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, it includes an electrocoagulation mechanism 1 for coagulating and hemostatically treating human tissue, and a switching mechanism 3 is provided on the outside of the electrocoagulation mechanism 1; An adjusting mechanism 2 for limiting the deflection angle of the electrocoagulation forceps, the adjusting mechanism 2 being connected to the adapter mechanism 3; The adapter mechanism 3 is used for connecting the electrocoagulation mechanism 1 and the regulating mechanism 2; The electrocoagulation mechanism 1 includes a main body 11, a frame 12 is provided on the top of the main body 11, and a pull rod 13 is slidably adapted inside the frame 12; The interior of the main body 11 is slidably fitted with a central push rod 18 and a sliding plate 19. The outer side of the central push rod 18 is fixedly connected to the sliding plate 19. The outer side of the sliding plate 19 is fixedly connected to a return spring 10. The end of the return spring 10 away from the sliding plate 19 is fixedly connected to the interior of the main body 11. The center push rod 18 is inserted into the inner side of the main body 11 and extends to the outside thereof, and is fixedly connected to the inclined block 101; by having the operator manually pull the handle 25 inward, it is deflected clockwise with the inner shaft 24 as the center, wherein the top end of the handle 25 is connected to the connecting bar 26, and the connecting bar 26 has a certain toughness, and its other end is fixedly connected to the center push rod 18, so the center push rod 18 will extend outward along the connecting head 31 and the main body 11 respectively, and the outer side of the center push rod 18 is connected to the sliding plate 19, and the outer side of the sliding plate 19 is connected to the return spring 10, and the sliding plate 19 and the return spring 10 are both inside the main body 11, so when the operator cancels the inward pulling force on the handle 25, the center push rod 18 will automatically reset under the action of the return spring 10. The other end of the center push rod 18 is connected to the inclined surface block 101. As the center push rod 18 extends outward with the inclined surface block 101, the upper and lower inclined surfaces of the inclined surface block 101 will squeeze the No. 1 clamp head 16 and the No. 2 clamp head 17 respectively. The No. 1 clamp head 16 and the No. 2 clamp head 17 are both centered on the axis in the support 15 and are symmetrically arranged up and down.

[0038] The outer end surface of the main body 11 is fixedly connected to a support 15, and the interior of the support 15 is rotatably mounted with a first clamp head 16 and a second clamp head 17 through a shaft, wherein the first clamp head 16 and the second clamp head 17 are both squeezed and adapted to the inclined surface block 101; The second clamp head 17 is provided with a cleaning assembly 14; The outer side of the shaft inside the support 15 is fixedly connected with a fixed sleeve 102, the inner side of the fixed sleeve 102 is fixedly connected with a sleeve rod 103, and the upper and lower ends of the sleeve rod 103 are fixedly connected with a toughness strip 104; Both ends of the No. 1 pliers head 16 and the No. 2 pliers head 17 are connected to the slider 105 by shaft rotation, the outer side of the slider 105 is fixedly connected to the toughness bar 104, and the end of the slider 105 away from the No. 1 pliers head 16 is slidably adapted with an arc rail 106, and the arc rail 106 is fixedly connected to the inner side of the support 15; wherein both ends of the No. 1 pliers head 16 and the No. 2 pliers head 17 are installed with the slider 105 by shaft rotation, and the slider 105 is slidably adapted in the arc rail 106 connected to the inner wall of the support 15, and the outer side of the slider 105 is connected to the sleeve rod 103 through the toughness bar 104, wherein the outer side of the sleeve rod 103 is connected to the support 15 through the fixed sleeve 102, so the sleeve rod 103 is fixed, and the toughness bar 104 is elastic and made of rubber. The arcuate rail 106 serves to increase the deflection stability of the first and second jaws 16, 17 and to limit their position, thereby preventing them from deflecting or having inconsistent deflection angles during the squeezing process of the ramp block 101. Furthermore, the arcuate rail 106 allows the operator to adjust the deflection angles of the first and second jaws 16, 17 simply by manually pulling the handle 25 inward. Release of the handle 25 automatically resets the first and second jaws 16, 17 to their initial positions.

[0039] The toughness strip 104 is used for resetting the No. 1 clamp head 16 and the No. 2 clamp head 17 .

[0040] The cleaning component 14 includes a U-shaped platform 141, which is arranged on the top of the No. 2 clamp head 17. The upper and lower sides of the inner cavity of the U-shaped platform 141 are fixedly connected with a trapezoidal platform 142. The outer end surface of the trapezoidal platform 142 is embedded with a sealing plate 143. The outer side of the sealing plate 143 is fixedly connected to a No. 1 magnetic block 144. The sealing plate 143 is fixedly connected to the pull strip 13; a frame 12 is provided on the main body 11, and the inner sliding of the frame 12 is adapted to be fitted with a pull strip 13, wherein the frame 12 plays a supporting role for the pull strip 13, and the other end of the pull strip 13 is connected to the cleaning component 14. In the process of hemostasis or ligation and suturing of tissue, the operator only needs to change the way of grasping the electrocoagulation forceps so that the lower three fingers hold the handle of the main body 21, and the fingers are buckled on the handle. On the handle 25, the thumb is then tilted upward and the turning handle 23 is deflected clockwise, and then the pull strip 13 fixedly connected to the top of the turning handle 23 is pulled and moves toward the direction of the main body 21, and the other end of the pull strip 13 is connected to the blocking plate 143, so the blocking plate 143 will move inward along the through rod 145, wherein the blocking plate 143 is initially embedded with the trapezoidal platform 142, and is embedded with the thickest part of the trapezoidal platform 142, but as the blocking plate 143 moves inward, a gap is generated between the two, so that the physiological saline stored in the U-shaped platform 141 will be discharged outward from the gap, and the part where the jaws and tissue are adhered is cleaned, thereby avoiding forced tearing and causing heavy bleeding.

[0041] The inner cavity of the U-shaped platform 141 is divided into two cavities by a central partition; the inner cavity of the U-shaped platform 141 is divided into two cavities by the partition, one of which is used to store physiological saline, and the other is connected to the external trachea, so that when burns occur between the jaws and tissue and a certain amount of smoke is generated, the trachea will absorb the smoke, thereby preventing the accumulation of smoke from affecting the operator's subsequent hemostasis or ligation.

[0042] A through rod 145 is inserted into the center of the blocking plate 143, and a fixed rod 146 is fixedly connected to the end of the through rod 145 away from the blocking plate 143. The fixed rod 146 is arranged inside the U-shaped platform 141, and the outer side of the fixed rod 146 is fixedly connected to the second magnetic block 147. The outer side of the blocking plate 143 is fixedly connected to the first magnetic block 144, and the fixed rod 146 is fixedly connected to the second magnetic block 147. The repulsive force is maintained between the two magnetic blocks, thereby playing a role in resetting the blocking plate 143 and the pull bar 13. Explanation: The blocking plate 143 is embedded with the trapezoidal platform 142, so it will not detach from the U-shaped platform 141. And the cleaning component 14 is detachable.

[0043] like Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, the adjustment mechanism 2 includes a main body 21, the outer side of the main body 21 is fixedly connected to a shaft seat 22, the inner side of the shaft seat 22 is rotatably mounted with a turning handle 23, and the top end of the turning handle 23 is fixedly connected to the pull bar 13; An inner shaft 24 is fixedly installed inside the main body 21 , a handle 25 is rotatably installed outside the inner shaft 24 , a connecting bar 26 is fixedly connected to the top of the handle 25 , and the end of the connecting bar 26 away from the handle 25 is fixedly connected to the central push rod 18 .

[0044] The adapter mechanism 3 includes a connector 31, one end of which is fixedly connected to the main body 21, and an end of the connector 31 away from the main body 21 is fitted with the main body 11, wherein the interior of the connector 31 is slidably fitted with the central push rod 18; The interior of the connector 31 is adapted to slide with a No. 1 plug-in block 32, and the end face of the No. 1 plug-in block 32 is fixedly mounted with a No. 2 plug-in block 33. The bottom of the inner cavity of the No. 2 plug-in block 33 is provided with a No. 1 inner groove 34. The interior of the No. 1 inner groove 34 is adapted to slide with an inner arc plate 35. The outer side of the inner arc plate 35 is extruded with an arc strip 36. The end of the arc strip 36 away from the inner arc plate 35 is fixedly connected to the interior of the connector 31. By inserting the main body 11 into the interior of the connector 31, the No. 1 plug-in block 32 and the No. 2 plug-in block 33 connected to the main body 11 are connected. The No. 1 plug 33 will also extend into the interior of the connector 31, and then the connector 31 will be deflected counterclockwise, so that the No. 1 plug 32 and the No. 2 plug 33 are completely embedded in the connector 31. At the same time, as the connector 31 is deflected, the arc strip 36 fixedly connected to the interior of the connector 31 will squeeze the inner arc plate 35 outward, so that the inner arc plate 35 will move outward along the No. 1 inner groove 34, so that the No. 2 plug 33 and the inner arc plate 35 will close the groove of the connector 31 and fit perfectly.

[0045] A second inner groove 37 is provided inside the No. 2 plug-in block 33, and the inner side of the No. 2 inner groove 37 is squeezed and adapted to the trapezoidal curved block 39. The bottom of the trapezoidal curved block 39 is connected to the No. 1 elastic telescopic rod 38 through a bearing. In addition, when the two need to be separated, it is only necessary to rotate the trapezoidal curved block 39 180 degrees so that the smaller part of the trapezoidal curved block is close to the No. 2 inner groove 37. At this time, the inner arc plate 35 will be retracted into the No. 2 plug-in block 33, and the trapezoidal curved block 39 will also be retracted into the inner arc plate 35, thereby facilitating the replacement and repair of the connector 31 or the main body 11.

[0046] The trapezoidal curved block 39 is deflected on the first elastic telescopic rod 38 through a bearing. In addition, both ends of the trapezoidal curved block 39 are curved surfaces with the same shape, but one end is thicker and the other end is thinner. In addition, when the inner arc plate 35 is extended outward, the trapezoidal curved block 39 will be squeezed by the No. 2 inner groove 37, so that the trapezoidal curved block 39 will be temporarily retracted into the inner arc plate 35 and compress the No. 1 elastic telescopic rod 38. When the inner arc plate 35 is fully extended, under the action of the No. 1 elastic telescopic rod 38, the trapezoidal curved block 39 will pop out again, and the thicker part of the trapezoidal curved block 39 is larger than the notch of the No. 2 inner groove 37, and the thinner part of the trapezoidal curved block 39 is smaller than the notch of the No. 2 inner groove 37. However, when the trapezoidal curved block 39 pops out, the thicker part is close to the No. 2 inner groove 37. Therefore, the trapezoidal curved block 39 can no longer return to the No. 2 plug-in block 33 through the No. 2 inner groove 37, thereby playing the role of self-locking the inner arc plate 35 and locking the main body 11 and the connector 31.

[0047] Positioning components 27 are symmetrically provided on both sides of the main body 21; The positioning assembly 27 includes an end rail 271, a second elastic telescopic rod 272 is fixedly connected to the bottom of the inner cavity of the end rail 271, and a top block 273 is fixedly connected to the top of the second elastic telescopic rod 272. There are multiple second elastic telescopic rods 272 and top blocks 273, and each top block 273 is in contact with each other. The inner sliding adaptor of the end rail 271 is equipped with a shift block 274, which is fixedly connected to the handle 25. A through-shaft 275 is rotatably installed inside the shift block 274. The inner and outer sides of the through-shaft 275 are respectively fixedly connected with an adjustment handle 276 and a deflection rod 277. The bottom end of the deflection rod 277 is fixedly connected with a column 278, and the column 278 is slidably adapted inside the shift block 274. When the operator rotates the handle 25 inward, the shift block 274 fixedly connected to its outer side will deflect along the end rail 271, wherein the center of the end rail 271 is the same as the center of the inner shaft 24. Therefore, when the handle 25 is rotated to the desired position, the shift block 274 fixedly connected to the outer side thereof will deflect along the end rail 271. When the predetermined angle is reached, the operator only needs to turn the adjustment handle 276 clockwise so that the deflection rod 277 connected to it through the same through shaft 275 will move downward, and the other end of the deflection rod 277 is connected to the column 278, so the column 278 will pass downward from the bottom of the shift block 274 and squeeze any top block 273 at its bottom. At the same time, the second elastic telescopic rod 272 connected to the bottom of the top block 273 will shrink, thereby limiting the shift block 274 and the handle 25, avoiding the operator from getting tired of constantly pressing the handle 25.

[0048] The portion where the deflection rod 277 and the column 278 are connected is elastic.

[0049] The bottom of the shifting block 274 is squeezed and fitted with the top block 273 , and is used to limit the position of the handle 25 .

[0050] When the present invention is in use: first, the operator manually pulls the handle 25 inward, causing it to deflect clockwise with the inner shaft 24 as the center of the circle, wherein the top end of the handle 25 is connected to the connecting strip 26, and the other end thereof is fixedly connected to the center push rod 18, so that the center push rod 18 will extend outward along the connecting head 31 and the main body 11 respectively. In addition, the outer side of the center push rod 18 is connected to the sliding plate 19, and the outer side of the sliding plate 19 is connected to the return spring 10, and the sliding plate 19 and the return spring 10 are both inside the main body 11. Therefore, when the operator cancels the pulling force on the handle 25 inward, the center push rod 18 will automatically reset under the action of the return spring 10, wherein the other end of the center push rod 18 is connected to the inclined plane block 101. As the center push rod 18 extends outward with the inclined plane block 101, the upper and lower inclined plane parts of the inclined plane block 101 will squeeze the No. 1 pliers head 16 and the No. 2 pliers head 17 respectively. Both ends of the No. 1 clamp head 16 and the No. 2 clamp head 17 are equipped with sliders 105 through shaft rotation, and the sliders 105 are slidably adapted in the arc rail 106 connected to the inner wall of the support 15. In addition, the outer side of the slider 105 is connected to the sleeve rod 103 through a toughness strip 104, and the outer side of the sleeve rod 103 is connected to the support 15 through a fixed sleeve 102.

[0051] A frame 12 is provided on the main body 11, and a pull strip 13 is slidingly adapted inside the frame 12, and the other end of the pull strip 13 is connected to the cleaning component 14. In the process of hemostasis or ligation and suturing of tissue, the operator only needs to change the way of grasping the electrocoagulation forceps, so that the lower three fingers hold the handle of the main body 21, and the lower three fingers are buckled on the handle 25, and then the thumb is tilted upward and the handle 23 is deflected clockwise, and then the pull strip 13 fixedly connected to the top of the handle 23 will be pulled and moved toward the main body. The blocking plate 143 moves in the direction of the U-shaped platform 141, and the other end of the pull rod 13 is connected to the blocking plate 143, so the blocking plate 143 moves inward along the through rod 145, wherein the blocking plate 143 is initially engaged with the trapezoidal platform 142, and is engaged with the thickest part of the trapezoidal platform 142, but as the blocking plate 143 moves inward, a gap is generated between the two. At this time, the physiological saline stored in the U-shaped platform 141 will be discharged outward from the gap and clean the part where the jaws and tissue are adhered.

[0052] By inserting the main body 11 into the interior of the connector 31, the No. 1 plug 32 and the No. 2 plug 33 connected to the main body 11 will also extend into the interior of the connector 31, and then the connector 31 is deflected counterclockwise, so that the No. 1 plug 32 and the No. 2 plug 33 are completely embedded in the connector 31. At the same time, as the connector 31 is deflected, the arc strip 36 fixedly connected to the interior of the connector 31 will squeeze the inner arc plate 35 outward, so that the inner arc plate 35 will move outward along the No. 1 inner groove 34, so that the No. 2 plug 33 and the inner arc plate 35 will close the notch of the connector 31 and fit perfectly.

[0053] In addition, when the inner arc plate 35 is extending outward, the trapezoidal curved block 39 will be squeezed by the No. 2 inner groove 37, so that the trapezoidal curved block 39 will be temporarily retracted into the inner arc plate 35 and compress the No. 1 elastic telescopic rod 38. When the inner arc plate 35 is fully extended, under the action of the No. 1 elastic telescopic rod 38, the trapezoidal curved block 39 will pop out again, and the thicker part of the trapezoidal curved block 39 is larger than the notch of the No. 2 inner groove 37, and the thinner part of the trapezoidal curved block 39 is smaller than the notch of the No. 2 inner groove 37. However, when the trapezoidal curved block 39 pops out, the thicker part is close to the No. 2 inner groove 37, so the trapezoidal curved block 39 can no longer pass through the No. 2 inner groove 37 to return to the No. 2 plug-in block 33.

[0054] When the operator turns the handle 25 inward, the shift block 274 fixedly connected to its outer side will deflect along the end rail 271, wherein the center of the end rail 271 is the same as the center of the inner shaft 24. Therefore, when the handle 25 is rotated to the predetermined angle, the operator only needs to turn the adjustment knob 276 clockwise so that the deflection rod 277 connected to it through the same through shaft 275 will move downward, and the other end of the deflection rod 277 is connected to the column 278, so the column 278 will pass downward from the bottom of the shift block 274 and squeeze any one of the top blocks 273 at its bottom, and at the same time, the second elastic telescopic rod 272 connected to the bottom of the top block 273 will shrink.

Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
