Description

Technical Field

[0001] This utility model belongs to the field of medical device accessories technology, and in particular relates to a dripping bipolar electrocoagulation forceps dripping pipeline structure. Background Technology

[0002] Bipolar electrocoagulation forceps are an indispensable precision hemostatic tool in modern surgery. Their core working principle utilizes a high-frequency current to form a closed circuit between the two forceps tips. When the current flows through the tissue held by the forceps tips, it generates localized high heat, causing the proteins within the tissue cells to denature and coagulate, thereby achieving the purpose of sealing blood vessels and effectively stopping bleeding. Current bipolar electrocoagulation forceps typically lack an internal water system, making it impossible to cool the forceps tips during surgery, thus affecting surgical outcomes.

[0003] For example, a Chinese invention patent application discloses a bipolar electrocoagulation forceps [application number: 202510550752.3]. This invention patent application includes a main forceps head, a sliding rod, a cannula, a handle, and a lighting lamp. The end of the cannula is located inside the handle, and the sliding rod is slidably located inside the cannula. The main forceps head includes two sub-forceps heads, and the main forceps head is located at the front end of the cannula. The sliding rod controls the opening and closing of the two sub-forceps heads by sliding back and forth. The lighting lamp is located at the front end of the cannula, and a liquid suction channel is formed between the cannula and the sliding rod.

[0004] This invention patent application has the advantage of significantly improving the clinical applicability and surgical efficiency of bipolar electrocoagulation forceps through the synergistic optimization of the main forceps head, integrated lighting and suction channel, but it still does not solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drip-feed bipolar electrocoating clamp drip-feeding pipe structure includes an inlet pipe located inside a flexible tube and an outlet pipe located inside a pull rod. The inlet pipe is connected to the outlet pipe through a water connection mechanism. One end of the pull rod passes through the water connection mechanism, and the other end is connected to the clamp head. The clamp head is provided with at least one drip hole, and the outlet pipe is connected to the drip hole through a drip pipe.

[0008] In the above-mentioned dripping bipolar electrocoagulation clamp dripping pipe structure, one end of the dripping hole extends to the outer surface of the clamp head, and the other end extends to the clamping surface of the clamp head.

[0009] In the above-mentioned dripping bipolar electrocoagulation clamp dripping pipe structure, the end of the pull rod near the clamp head is also provided with a pull rod connecting section.

[0010] In the above-mentioned dripping bipolar electrocoagulation clamp dripping pipe structure, an isolation seat is provided between the clamp head and the pull rod connecting section. The isolation seat is rotatably connected to the pull rod connecting section. The end of the dripping pipe away from the pull rod connecting section extends into the isolation seat and communicates with the dripping hole. The outer wall of the dripping pipe is sealed to the inner wall of the isolation seat.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] This embodiment provides a dripping bipolar electrocoating clamp dripping pipe structure, combined with... Figure 1 and Figure 5 As shown, it includes an inlet pipe 1 located inside the hose 5 and an outlet pipe 2 located inside the pull rod 3. The inlet pipe 1 is connected to the outlet pipe 2 through a water connection mechanism 100. One end of the pull rod 3 passes through the water connection mechanism 100, and the other end is connected to the clamp head 7. The clamp head 7 is provided with at least one drip hole 201. The outlet pipe 2 is connected to the drip hole 201 through a drip pipe 202.

[0031] In this invention, during use, the flexible hose 5 is connected to an external water source. Water is sequentially delivered to the surface of the forceps head 7 through the inlet pipe 1, the water connection mechanism 100, the outlet pipe 2, the drip pipe 202, and the drip hole 201, thereby cooling the forceps head 7. Therefore, this invention fully utilizes the existing structure of bipolar electrocoagulation forceps, placing the outlet pipe 2 inside the pull rod 3 and the drip hole 201 at the forceps head 7 position. This allows the entire drip pipe structure to be well integrated into the existing bipolar electrocoagulation forceps, while simultaneously cooling the forceps head during surgery to ensure surgical effectiveness.

[0032] Combination Figure 5 and Figure 6 As shown, one end of the drip hole 201 extends to the outer surface of the clamp head 7, and the other end extends to the clamping surface of the clamp head 7. In this way, water for cooling can be delivered to the surface and clamping surface of the clamp head 7, and multiple surfaces are cooled simultaneously to improve the cooling effect.

[0033] like Figure 6 As shown, the pull rod 3 is provided with a pull rod connecting section 203 at one end near the pliers head 7. One end of the pull rod connecting section 203 extends into the pull rod 3. One end of the drip pipe 202 extends into the pull rod connecting section 203 and is connected to the water outlet pipe 2. The outer wall of the drip pipe 202 is sealed to the inner wall of the pull rod connecting section 203. An isolation seat 204 is also provided between the pliers head 7 and the pull rod connecting section 203. The isolation seat 204 is rotatably connected to the pull rod connecting section 203. The end of the drip pipe 202 away from the pull rod connecting section 203 extends into the isolation seat 204 and is connected to the drip hole 201. The outer wall of the drip pipe 202 is sealed to the inner wall of the isolation seat 204.

[0034] Preferably, the surface of the isolation seat 204 is provided with a strip groove 205 that is recessed into the interior of the isolation seat 204, and the drip pipe 202 is made of elastic material and is embedded in the strip groove 205.

[0035] The drip tube 202 is fitted into the strip groove 205 to limit the position of the drip tube 202, preventing it from shifting significantly when the forceps head 7 rotates or opens and closes during the operation.

[0036] The drip tube 202 is made of an elastic material, allowing it to deform as needed during use to adapt to different application scenarios. Both ends of the drip tube 202 can be easily and conveniently glued and sealed.

[0037] like Figure 1 As shown, a flow controller 8 is also provided on the hose 5. A control roller 9 is rotatably connected inside the flow controller 8. The hose 5 passes through the flow controller 8 and the control roller 9 is pressed against the surface of the hose 5. Rolling the control roller 9 can squeeze the hose 5 to control the opening of the hose 5. The flow controller 8 can adopt a specific structure commonly used in the prior art. The rolling of the control roller 9 is used to control the amount of water dripping at the clamp head 7.

[0038] Combination Figure 2-4 As shown, the water connection mechanism 100 includes a connecting seat 101 with a water passage cavity 102 inside. The water inlet pipe 1 is connected to the water passage cavity 102. The connecting seat 101 is provided with a through hole 103 that passes through the connecting seat 101. The pull rod 3 passes through the through hole 103. The water outlet pipe 2 is located inside the pull rod 3. The side wall of the pull rod 3 is also provided with a water inlet 104. The water passage cavity 102 and the water outlet pipe 2 are connected through the water inlet 104.

[0039] During surgery, the bipolar electrocoagulation forceps require rotating the lever 3 to rotate the forceps head, thereby enabling surgical manipulation at different sites on the patient. In use, water enters the water-passing cavity 102 through the inlet pipe 1, then flows from the water-passing cavity 102 through the inlet 104 to the outlet pipe 2, and finally, the outlet pipe 2 delivers the water to the area requiring cooling. In this invention, the lever 3 passes through the connecting seat 101 via the through hole 103, ensuring that the water-passing cavity 102 surrounds the lever 3. It is connected to the water-passing cavity 102 via the inlet 104 located on the side wall. This ensures communication with the water-passing cavity 102 even when the lever 3 rotates during surgery, thus expanding its application range.

[0040] like Figure 4 As shown, it also includes at least two sealing rings 105. The side of the connecting seat 101 is provided with a sealing groove 106 that is recessed into the connecting seat 101. The sealing rings 105 are accommodated in the sealing groove 106 and are located between the pull rod 3 and the connecting seat 101. The water inlet 104 is located between the two sealing rings 105.

[0041] By placing the inlet 104 between the two sealing rings 105, it can be ensured that the connection point between the water passage cavity 102 and the inlet 104 is also located between the two sealing rings 105, thereby ensuring the overall sealing performance and preventing water from overflowing.

[0042] Combination Figure 2 and Figure 4 As shown, it also includes a gasket 107 pressed on the side of the sealing ring 105, the gasket 107 being configured one-to-one with the sealing ring 105, and a retaining spring 108 pressed on the surface of the gasket 107 away from the sealing ring 105, the retaining spring 108 being configured one-to-one with the gasket 107, the surface of the pull rod 3 is provided with a retaining spring mounting groove 109, and the retaining spring 108 is embedded in the retaining spring mounting groove 109.

[0043] During surgery, the bipolar electrocoagulation forceps require the lever 3 to be moved back and forth to control the opening or closing of the forceps head, thereby completing the surgical operation. Using the above connection method, the connecting seat 101 and the lever 3 can be fixed axially, so that when the lever 3 moves back and forth, the connecting seat 101 can move synchronously back and forth.

[0044] Preferably, the centerlines of the gasket 107, the sealing ring 105, and the pull rod 3 coincide. This ensures a good sealing effect and reliable axial connection between the connecting seat 101 and the pull rod 3.

[0045] like Figure 4 As shown, the water inlet pipe 1 is located inside the flexible hose 5, and a water inlet connector 110 extends from the lower surface of the connector 101. The water inlet connector 110 is sleeved inside the flexible hose 5 and connected to the water inlet pipe 1. This ensures the reliability of the connection at the water inlet.

[0046] like Figure 2 As shown, the connecting seat 101 is also provided with a conductive mounting groove 111 for mounting the conductive spring 6. One end of the conductive mounting groove 111 passes through the upper surface of the connecting seat 101, and the other end passes through the side of the connecting seat 101.

[0047] Preferably, the bottom surface of the conductive mounting groove 111 is provided with a clamping protrusion 112, and a corresponding clearance groove 113 is provided above the clamping protrusion 112, and the conductive spring 6 is pressed on the clamping protrusion 112.

[0048] The conductive mounting groove 111 on the connector 101 allows for the installation of the conductive spring 6, enabling the water system and electrical system to be better integrated within the electrocoating clamp. A locking protrusion 112 is also provided to ensure the secure installation of the conductive spring 6.

[0049] Example 2

[0050] This embodiment provides a dripping bipolar electrocoagulation clamp dripping pipe structure, which is generally the same as that in embodiment 1. The only difference is the way the connecting seat 101 is set. Specifically, the connecting seat 101 is fixedly connected to the outer shell 4, and the pull rod 3 passes through the connecting seat 101 through the through hole 103 and is slidably connected to the connecting seat 101. During the sliding process of the pull rod 3, the water inlet 104 is always located between the two sealing rings 105.

[0051] In Embodiment 1, the connecting seat 101 is axially fixed to the pull rod 3, so that the connecting seat 101 moves synchronously during the back-and-forth movement of the pull rod 3. However, this solution inevitably causes many components to move during the movement, such as the flexible hose 5, the conductive spring 6, and the wire structure connected to the conductive spring 6, which move axially, thus requiring further improvement in the overall structural stability. Therefore, this embodiment improves upon this by fixing the connecting seat 101 to the outer shell 4, so that the connecting seat 101 and other structures connected to it remain fixed during the back-and-forth sliding of the pull rod 3. Commonly used sealing elements in the prior art, such as O-rings as sealing rings 105, can also ensure a seal when the pull rod 3 and the connecting seat 101 slide relative to each other. However, in this embodiment, the connecting seat 101 needs to be made larger in the axial direction of the pull rod 3 so that the water passage cavity 102 can be set large enough, that is, there can be a sufficient distance between the two sealing rings 105, so that the water inlet 104 is always located between the two sealing rings 105 during the sliding process of the pull rod 3, thus avoiding water leakage.

[0052] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0053] Although this document frequently uses terms such as inlet pipe 1, outlet pipe 2, pull rod 3, outer casing 4, hose 5, conductive spring 6, clamp head 7, flow controller 8, brake roller 9, water connection mechanism 100, connecting seat 101, water passage cavity 102, through hole 103, water inlet 104, sealing ring 105, sealing groove 106, gasket 107, snap ring 108, snap ring mounting groove 109, water inlet connector 110, conductive mounting groove 111, clamping protrusion 112, clearance groove 113, drip hole 201, drip pipe 202, pull rod connecting section 203, isolation seat 204, and strip groove 205, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
