Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a drip control component and drip electrocoagulation forceps suitable for drip electrocoagulation forceps. Background Technology

[0002] Bipolar electrocoagulation is used in microsurgery to electrocoagulate blood vessels in microvessels. Its working principle involves forceps connected to the electrocoagulator via leads. The forceps tips clamp the bleeding point, and the electrocoagulator releases current, forming a circuit between the two forceps tips. This provides high-frequency electrical energy to the lesion tissue, causing the blood vessels between the two ends of the bipolar forceps to dehydrate, denature, and coagulate. Because the current flows only between the two forceps tips, it does not cause burns to other areas, making it ideal for various microsurgical procedures. However, during hemostasis, the forceps tips are prone to eschar adhesion. This not only creates an insulation effect, rendering electrocoagulation ineffective, but also causes tissue to adhere to the forceps, leading to secondary damage and rebleeding when the forceps are removed. Therefore, to prevent tissue charring and adhesion during hemostasis, those skilled in the art require electrode forceps with a dripping function.

[0003] For example, CN219000548U discloses a drip electrocoagulation forceps and an electrocoagulation device, which includes a forceps body with a tubular structure. The inner wall of the forceps body forms a first flow channel, which extends through the forceps body axially. A forceps tip is fixedly connected to the forceps body and forms an integral forceps blade. The end of the forceps tip near the forceps body is hollow and forms a second flow channel, which communicates with the first flow channel. A drip outlet is provided at the end of the forceps tip away from the forceps body, and the drip outlet communicates with the second flow channel. In operation, the drip outlet is suitable for guiding physiological saline in the first and second flow channels to the wound surface. While this electrocoagulation forceps can achieve a dripping effect, it lacks a convenient structure for controlling the dripping process.

[0004] Based on the deficiencies of the aforementioned disclosed technologies, CN114515190B discloses a self-drip bipolar electrocoagulation tweezers, which includes an electrode base, tweezer handles on both sides of the electrode base, conductive tips connected to the tweezer handles, a flow guide tube on the tweezer handles, and a control mechanism for controlling the flow guide tube sleeved on the tweezer handles. The control mechanism includes a control housing sleeved on the tweezer handles, a through hole for penetrating the flow guide tube on the control housing, a control groove on the control housing, a control rod movably disposed in the control groove, a pressing rod at one end of the control rod facing the through hole, a control button connected to the other end of the control rod, a first spring sleeved on the pressing rod at one end of the control groove near the through hole, an elastic limiting plate on the control rod, a limiting block at one end of the elastic limiting plate away from the control rod, and a closed groove communicating with the control groove on the outside of the control housing. Based on this disclosed technology, when the electrocoagulation forceps are needed for dripping, the doctor can use a tool or hand to press the limiting block to disengage it from the closed groove. Under the action of the first spring, the control rod moves towards the control button, causing the pressing rod to disengage from the drainage tube, thus releasing the drainage tube from its closed state and restarting the dripping function. This not only achieves long-term self-sealing and self-connection of the drainage tube, but also allows the degree of deformation of the drainage tube to be controlled by pressing the control button, so as to control the dripping speed (without pressing the control button all the way down).

[0005] Based on the aforementioned publicly available technology, research and trials have revealed a problem with its operational convenience. Specifically, during the operation of the control mechanism, medical personnel need to use a single hand to press it. However, due to the limited size of the electrocoagulation forceps for operational flexibility and convenience, the operable space is restricted. Under these limited conditions, medical personnel may use one hand to hold the pair of handles of the electrocoagulation forceps while using the other hand to press the control mechanism, potentially causing interference between the two hands and affecting the overall operational flexibility. In actual surgical procedures, electrocoagulation forceps need to be used in conjunction with other surgical instruments, such as surgical forceps, to facilitate the gripping and control of the area to be electrocoagulated, thereby improving the smoothness of the electrocoagulation process. Furthermore, in the actual electrocoagulation process, in order to achieve hemostasis as quickly as possible, the overall operation requires to be as fast and accurate as possible. Therefore, in the actual surgical process, dripping water while performing electrocoagulation does not require repeated and tedious adjustments to the dripping speed. In addition, considering the disposable nature of medical consumables, a cumbersome structure would increase the cost of medical devices and the amount of medical waste.

[0006] Therefore, the current electrocoagulation tweezers, which are equipped with dripping and dripping control functions, still have the problem of not being convenient and flexible enough in use. Further improvements are needed to the dripping control structure of the electrocoagulation tweezers. Utility Model Content

Water pipe, its passageway through the pipe body; The press-adjustable control includes a control body partially placed in the control box and partially extending out of the control box, and a water passage provided in the part of the control body placed in the control box, suitable for a water pipe to pass through; the water passage is connected to the pipe body channel. An elastic element is located between the control body and the inner wall of the control box; When the pair of tweezers are open relative to each other and the elastic element is in a natural elastic state, one side wall of the water passage is adapted to squeeze the water pipe to cut off the water flow in the water pipe; when the pair of tweezers are close together relative to each other to compress the control body and the elastic element is in a compressed deformation state, the side wall of the water passage releases the squeezing of the water pipe to restore the water flow in the water pipe.

[0010] In an optional embodiment of this utility model, the control box is provided with a receiving cavity for assembling the control body; The control body slides into the receiving cavity, and the relative sliding direction between the control body and the receiving cavity is perpendicular to the flow direction of the water in the water pipe; and the elastic element is adapted to stretch and deform along the relative sliding direction between the control body and the receiving cavity.

[0011] In an optional embodiment of this utility model, the sidewall of the water passage suitable for squeezing the water pipe is a V-shaped wall, and the cone tip of the V-shaped wall faces the water pipe.

[0012] In an optional embodiment of this utility model, the elastic element is disposed in the water passage between the side end face of the water pipe facing away from the water pipe and the inner wall of the control box, which is suitable for squeezing the side wall of the water pipe.

[0013] In an optional embodiment of this utility model, the cross-section of the water passage along the relative sliding direction between the control body and the receiving cavity is a rectangular cross-section, and the width of the rectangular cross-section is not less than the outer diameter of the water pipe.

[0014] In an optional embodiment of this utility model, the cross-section of the pipe channel along the relative sliding direction between the control body and the receiving cavity is a circular cross-section, and the inner diameter of the circular cross-section is larger than the outer diameter of the water pipe.

This causes the forceps to move towards the control box, thereby compressing and deforming the elastic element and releasing the pressure on the water pipe from the side wall of the water passage, thus restoring the water flow in the water pipe. Therefore, for the drip electrocoagulation forceps of this embodiment, no additional control process for dripping is required while performing electrocoagulation, thus simplifying the operation of the entire drip electrocoagulation forceps and improving its convenience and efficiency in surgical operations.

[0022] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] Example 1: Please see Figures 1 to 6 As shown, this embodiment provides a drip control component suitable for drip electrocoagulation tweezers, which includes at least: a control box 11, a water pipe 12, and a press control.

[0024] Specifically, firstly, a control box 11 is fixed to the side end face of one of the two tweezers 2 of the dripping electrocoagulation tweezers, facing the other tweezers 2; the control box 11 has a tube channel 17 extending along the length of the tweezers 2. For ease of manufacturing, the control box 11 can be a regular, for example, but not limited to, cuboid structure. A water pipe 12 passes through the tube channel 17 along the length of the tweezers 2.

[0025] Secondly, there is the press-adjustment control, which includes a control body 13 partially placed in the control box 11 and partially protruding outside the control box 11, and a water passage 14 located in the part of the control body 13 placed inside the control box 11, suitable for the passage of the water pipe 12; the water passage 14 is connected to the pipe channel 17. It should be noted that, here, for the control body 13, part of it protrudes from the side of the control box 11 opposite to the tweezers 2 connected to it. That is to say, for the control box 11, one end face is connected to the tweezers 2, while the control body 13 protrudes from the other opposite side end face of the control box 11. With this design, the other tweezers 2 in the drip electrocoagulation tweezers that is not connected to the control box 11 can generate a pushing force on the part of the control body 13 protruding outside the control box 11 through the relative closing movement of a pair of tweezers 2, so that the control body 13 can be further extended into the control box 11 under the pushing force.

[0026] It should be noted that an elastic element 15 is provided between the control body 13 and the inner wall of the control box 11. This elastic element 15 is adapted to stretch and deform along the relative closing and opening directions of the pair of tweezers 2. For the elastic element 15 here, a spring may be selected, for example, but not limited to, a spring.

[0027] Based on the above structure, when the pair of tweezers 2 are relatively open and the elastic element 15 is in a natural elastic state, one sidewall of the water passage 14 is adapted to squeeze the water pipe 12 to cut off the water flow in the water pipe 12. When the pair of tweezers 2 are relatively close together to compress the control body 13 and the elastic element 15 is in a compressed deformation state, the sidewall of the water passage 14 releases the compression on the water pipe 12 to restore the water flow in the water pipe 12. That is to say, when the pair of tweezers 2 are relatively open, the water flow in the water pipe 12 can flow normally, while when the pair of tweezers 2 are relatively close together, the water flow in the water pipe 12 is blocked by the action of one sidewall of the water passage in the control body 13, thereby cutting off the water flow in the water pipe 12.

[0028] Next, referring to the accompanying drawings, it is necessary to describe in more detail that the control box 11 is provided with a receiving cavity for assembling the control body 13, and an opening communicating with the receiving cavity is opened on the side end face of the control box 11 facing away from the tweezers 2 connected thereto, so that the control body 13 can slide and engage with the receiving cavity through the opening, and the relative sliding direction between the control body 13 and the receiving cavity is perpendicular to the flow direction of the water in the water pipe 12; and the elastic member 15 is adapted to stretch and deform along the relative sliding direction between the control body 13 and the receiving cavity.

[0029] In one optional embodiment, the sidewall of the water passage 14 suitable for compressing the water pipe 12 is a V-shaped wall 16, with the conical tip of the V-shaped wall 16 facing the water pipe 12. An elastic member 15 is disposed between the side end face of the sidewall of the water passage 14 suitable for compressing the water pipe 12, facing away from the water pipe 12, and the inner wall of the regulating box 11. Through the design of the V-shaped wall 16, while satisfying the function of compressing the water pipe 12 to cut off the water flow in the water pipe 12, the contact area between the V-shaped wall 16 and the water pipe 12 can also be reduced.

[0030] Furthermore, it should be noted that, in order to meet the requirement of the V-shaped wall 16 of the water passage 14 to intercept the water flow in the water pipe 12, firstly, the cross-section of the water passage 14 along the relative sliding direction between the control body 13 and the receiving cavity is a rectangular cross-section, and the width of this rectangular cross-section is not less than the outer diameter of the water pipe 12. Based on this, it can be ensured that the water flow in the water pipe 12 is normal when the V-shaped wall 16 of the water passage 14 does not compress the water pipe 12. The cross-section of the pipe channel 17 along the relative sliding direction between the control body 13 and the receiving cavity is a circular cross-section, and the inner diameter of this circular cross-section is larger than the outer diameter of the water pipe 12. Furthermore, when the pair of tweezers 2 are relatively open and the elastic element 15 is in a natural elastic state, the side wall portion of the water passage 14 suitable for compressing the water pipe 12 is located in the pipe channel 17. In other words, when the elastic element 15 is in its natural elastic state, part of the V-shaped wall 16 of the water passage 14 enters the pipe channel 17, thus reducing the space left for the water pipe 12 at the part of the pipe channel 17 corresponding to the water passage 14. Of course, it can be understood that when the pair of tweezers 2 are relatively close together and the elastic element 15 is in a compressed deformation state, part of the side wall of the water passage 14 suitable for squeezing the water pipe 12 can still be located in the pipe channel 17, as long as no pressure is formed on the outer wall of the water pipe 12.

[0031] In summary, regarding the drip control component of the electrocoagulation forceps of this embodiment, by setting the drip control component on the side end face of one of the pair of forceps 2 facing the other, when medical personnel operate the electrocoagulation forceps, during the process of squeezing the pair of forceps 2 to electrocoagulate the wound, the pair of forceps 2 naturally generate a pushing force on the control body 13, causing it to move into the control box 11. This causes the elastic element 15 to be compressed and deformed, thereby releasing the pressure on the water pipe 12 from the side wall of the water passage 14 and restoring the water flow in the water pipe 12. Therefore, for the electrocoagulation forceps of this embodiment, no additional control process for the drip operation is required while performing the electrocoagulation operation, thus simplifying the operation process of the overall electrocoagulation forceps and improving its convenience and efficiency in surgical operation.

[0032] Example 2: Please see Figures 1 to 6 As shown, based on the drip control component for drip electrocoagulation tweezers in Embodiment 1, this embodiment provides a drip electrocoagulation tweezers, including at least: a tweezers body 3, a pair of tweezers plates 2 connected to the tweezers body 3, and the drip control component for drip electrocoagulation tweezers in Embodiment 1. To meet the practical needs of dripping, each pair of tweezers plates 2 is pre-set with a water channel 21; and each pair of tweezers plates 2 is equipped with a pair of water pipes 5, and both water pipes 5 are partially inserted into the control box 11 and connected to the water pipe 12; the water pipe 12 located outside the control box 11 is also equipped with a water inlet 18. It is understood that the tweezers plates 2 in this embodiment are also designed with a water outlet 19 near the tweezers tip 4. The structure and implementation principle of the water channel 21 and the water outlet 19 on the tweezers plates 2 can adopt mature methods in the prior art, such as, but not limited to, the technology disclosed in announcement number CN219000548U. This embodiment will not elaborate further on this.

[0033] Based on the above structure, the control box 11 is also provided with through holes suitable for the one-to-one insertion of a pair of water pipes 5, and a connecting pipe 6 is provided between the water pipe 12 and the pair of water pipes 5; a U-shaped transition is formed between the connecting pipe 6 and the water pipe 12. That is to say, the water pipe 12 allows external water to enter the water pipe 12 through the configured water inlet 18, and then enters the pair of water pipes 5 through the connecting pipe 6, and finally enters the water passage 21 on the tweezers 2 one-to-one through the pair of water pipes 5.

[0034] In summary, the dripping electrocoagulation forceps of this embodiment do not require additional control of the dripping process during use. Instead, the dripping effect can be achieved simultaneously with the electrocoagulation operation, thus greatly improving the operational comfort of medical staff during surgery.
