[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This multi-point adjustable negative pressure smoke extraction electrocoagulation clamp, through the coordinated use of the movable rod, the storage block, and the blocking block, allows for adjustment of the length of the inner cylinder and the support. Simply press the storage block to slide it against the inner wall of the storage groove, compressing the spring to deform and contract. At this time, the storage block drives the limiting block to contract against the inner wall of the storage groove and the limiting groove, causing the blocking block to lose its blocking effect. Then, the movable rod can slide between the inner walls of the outer cylinder, thereby driving the baffle, the inner cylinder, and the slip ring to slide against the inner wall of the sliding chamber, thus achieving the purpose of adjusting the inner cylinder and the support. This allows the support to drive the clamps one and two to better assist in the treatment of the patient.

[0013] 2. This negative pressure smoke extraction electrocoagulation clamp features multi-point adjustable design. Through the coordinated use of the adapter block and the locking block, when the auxiliary handle needs replacement due to wear or breakage after prolonged use, simply pull the handle outward. This causes the handle to deform and stretch the second spring. The outward pulling force applied to the handle causes the locking block to slide outward along the inner wall of the slot until it separates from the inner wall of the slot. At this point, the auxiliary handle can be removed for replacement. After the new auxiliary handle is reinserted into the inner wall of the circular slot, the locking block is slid to the slot outside the adapter block. Then, the handle is released. The elastic potential energy of the second spring causes the locking block to re-engage with the slot on the outer edge of the auxiliary handle, thus fixing and restricting the new auxiliary handle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 A negative pressure smoke exhaust electrocoagulating clamp with multi-point adjustable features includes an outer cylinder 1. The inner cavity of the outer cylinder 1 has a sliding chamber 2, and the outer edge of the outer cylinder 1 has a sliding groove 3. A sliding ring 6 is slidably connected to the inner wall of the sliding chamber 2. An inner cylinder 4 is fixedly installed on the inner wall of the sliding ring 6. A fixed cylinder 5 is fixedly installed on the inner wall of the inner cylinder 4. A baffle 7 and a baffle 8 are fixedly installed at the front and rear ends of the fixed cylinder 5, respectively. A movable rod 9 is fixedly installed on the outer side of the baffle 7. A receiving groove 10 is formed on the inner wall of the movable rod 9. A spring 11 is provided on the inner wall of the receiving groove 10. A limiting groove 12 is formed on the inner wall of the receiving groove 10, and a limiting block 1 is slidably connected to the inner wall of the limiting groove 12. 3. A storage block 14 is fixedly installed on the extension end of spring 11. A bracket 15 is slidably connected to the inner cavity of the fixed cylinder 5. A connecting rod 16 is fixedly installed on the outer side of the bracket 15. A connecting rod 27 is fixedly installed on the outer edge of the connecting rod 16. An adapter block 18 is fixedly installed at the bottom of the connecting rod 27. A circular groove 19 is opened at the bottom of the adapter block 18. An auxiliary handle 20 is slidably connected to the inner wall of the circular groove 19. A slot 21 is opened on the outer side of the adapter block 18 and the auxiliary handle 20. A locking block 22 is slidably connected to the inner wall of the slot 21. A pull handle 24 is fixedly installed at the outer end of the locking block 22. A spring 23 is provided on the outer side of the adapter block 18.

[0024] In the above structure, through the coordinated use of the movable rod 9, the storage block 14, and the blocking block 34, when it is necessary to adjust the length of the inner cylinder 4 and the support 15, simply press the storage block 14 so that it slides toward the inner wall of the storage groove 10 and compresses the spring 11 to deform and contract. At this time, the storage block 14 drives the limiting block 13 to contract on the inner wall of the storage groove 10 and the limiting groove 12, so that the blocking effect of the blocking block 34 on the storage block 14 disappears. Then, the movable rod 9 can slide between the inner walls of the outer cylinder 1, thereby driving the baffle 7, the inner cylinder 4, and the slip ring 6 to slide on the inner wall of the sliding chamber 2, thereby achieving the purpose of adjusting the inner cylinder 4 and the support 15, so that the support 15 can drive the clamp 25 and the clamp 28 to better assist the patient in treatment.

[0025] In a preferred embodiment: the storage block 14 is slidably connected to the inner wall of the storage groove 10, and the limiting block 13 is fixedly installed on the outer side of the storage block 14. The movable rod 9 is slidably connected to the inner wall of the outer cylinder 1, and the inner wall of the outer cylinder 1 is fixedly installed with a blocking block 34. The storage block 14 is slidably connected to the outer side of the blocking block 34.

[0026] In the above structure, the sliding of the limiting block 13 and the storage block 14 can be limited by the setting of the limiting groove 12.

[0027] In a preferred embodiment: connecting rod 17 is slidably connected to the inner wall of the groove 3, adapter block 18 is slidably connected to the outer edge of the outer cylinder 1, locking block 22 is adapted to the diameter of the locking groove 21, and a fixed handle 32 is fixedly installed on the outer edge of the outer cylinder 1.

[0028] In the above structure, through the cooperation of the adapter block 18 and the locking block 22, when the auxiliary handle 20 needs to be replaced due to wear or breakage after long-term use, simply pull the handle 24 outward. At this time, the handle 24 drives the spring 23 to deform and stretch. Through the outward pulling force applied to the handle 24, the handle 24 can drive the locking block 22 to slide outward on the inner wall of the slot 21 until the locking block 22 separates from the inner wall of the slot 21. At this time, the auxiliary handle 20 can be removed for replacement. After the new auxiliary handle 20 is reinserted into the inner wall of the circular groove 19, the locking block 22 is slid to the slot 21 outside the adapter block 18. Then, the handle 24 is released. Using the elastic potential energy of the spring 23 itself, the locking block 22 can be driven to re-engage with the slot 21 on the outer edge of the auxiliary handle 20, thereby fixing and restricting the new auxiliary handle 20.

[0029] In a preferred embodiment: a clamp 25 is rotatably connected to the inner wall of the bracket 15, a rotating groove 26 extends through the inner wall of the clamp 25, a fixing rod 27 is fixedly installed on the inner wall of the bracket 15, the rotating groove 26 and the fixing rod 27 are rotatably sleeved together, a round rod 29 is fixedly installed on the inner wall of the clamp 25, a clamp 28 is rotatably connected to the inner wall of the bracket 15, a rotating groove 30 extends through the inner wall of the clamp 28, the rotating groove 30 and the round rod 29 are rotatably sleeved together, and a spring 31 is provided between the clamp 28 and the inner wall of the clamp 25.

[0030] In the above structure, through the combined use of spring 31, fixing rod 27, and round rod 29, when the auxiliary handle 20 is pulled outward, the auxiliary handle 20 drives connecting rod 27 and connecting rod 16, thereby causing the bracket 15 to slide outward in the inner cavity of the fixing cylinder 5. After clamp 1 25 and clamp 2 28 slide out of the inner cavity of the fixing cylinder 5, the setting of spring 31 allows clamp 2 28 to open with clamp 1 25, thereby providing auxiliary treatment for the patient.

[0031] In a preferred embodiment, one end of the second spring 23 is fixedly installed on the inside of the handle 24, and the other end is fixedly installed on the outside of the adapter block 18.

[0032] In the above structure, by setting the second spring 23, when it is necessary to automatically reset the locking block 22, simply slide the locking block 22 into the locking groove 21 on the outside of the adapter block 18, and then release the pull handle 24. Then, the elastic potential energy of the second spring 23 itself can drive the locking block 22 back to its original position, thereby achieving the purpose of locking and limiting the auxiliary handle 20.

[0033] In a preferred embodiment: the bracket 15 is slidably connected to the inner cavity of the fixed cylinder 5, the first baffle 7 and the second baffle 8 overlap with the bracket 15, and the outer edge of the outer cylinder 1 is provided with a smoke exhaust pipe 33.

[0034] In the above structure, the baffle 7 and the baffle 8 prevent the bracket 15 from sliding out of the inner cavity of the fixed cylinder 5, thus limiting the bracket 15.

[0035] Working principle: When this device is needed, it can first be used in conjunction with the movable rod 9, the storage block 14, and the blocking block 34. Then, when the length of the inner cylinder 4 and the support 15 needs to be adjusted, simply press the storage block 14, causing it to slide towards the inner wall of the storage groove 10 and compress the spring 11, causing it to deform and contract. At this time, the storage block 14 drives the limiting block 13 to contract within the inner walls of the storage groove 10 and the limiting groove 12, causing the blocking effect of the blocking block 34 on the storage block 14 to disappear. Then, the movable rod 9 can slide between the inner walls of the outer cylinder 1, thereby causing the baffle 7, the inner cylinder 4, and the slip ring 6 to slide within the inner wall of the sliding chamber 2, thus achieving the purpose of adjusting the inner cylinder 4 and the support 15. This allows the support 15 to better assist the patient in treatment by driving the clamps 25 and 28. Secondly, using the adapter... The cooperation of block 18 and locking block 22 allows the auxiliary handle 20 to be replaced after prolonged use due to wear or breakage. Simply pull the handle 24 outward, causing the spring 23 to deform and stretch. The outward pulling force applied to the handle 24 causes the locking block 22 to slide outward on the inner wall of the slot 21 until the locking block 22 separates from the inner wall of the slot 21. At this point, the auxiliary handle 20 can be removed for replacement. After the new auxiliary handle 20 is reinserted into the inner wall of the circular groove 19, the locking block 22 is slid to the slot 21 on the outer side of the adapter block 18. Then, the handle 24 is released, and the elastic potential energy of the spring 23 causes the locking block 22 to re-engage with the slot 21 on the outer edge of the auxiliary handle 20, thus fixing and restricting the new auxiliary handle 20.
