Description

Technical Field

[0001] This utility model belongs to the field of medical device accessories technology, and in particular relates to a water circuit connection mechanism for bipolar electrocoagulation forceps. Background Technology

[0002] Some existing surgical instruments incorporate water channels as needed, but most of these channels are directly connected to an external water source. This connection method results in poor flexibility of the water channel structure itself, making it unsuitable for use during surgery where some components of the surgical instrument require rotation or other movements, thus limiting its application scenarios.

[0003] For example, a Chinese utility model patent discloses a surgical forceps [Application No.: 202321082200.7]. This utility model patent includes a fixed handle and a movable handle, hinged together; a fixed forceps body connected to the fixed handle; a movable forceps body connected to the movable handle and adapted to move relative to the fixed forceps body; a water passage groove disposed on the fixed forceps body and arranged along the length direction of the fixed forceps body, one end of the water passage groove passing through the head of the fixed forceps body to form a water outlet, and the other end of the water passage groove extending to the tail of the fixed forceps body to form a water inlet, the water inlet being used to connect a water pipe; and an optical path groove disposed on the fixed forceps body and positioned... On one side of the water channel, one end of the optical channel penetrates the head of the fixing clamp and the other end extends to the tail of the fixing clamp to form an optical path entrance; an electrocoagulation end channel is disposed on the fixing clamp and adjacent to the optical channel, one end of the electrocoagulation end channel penetrates the head of the fixing clamp and the other end extends to the tail of the fixing clamp, an electrocoagulation end is disposed in the electrocoagulation end channel, and a wire is connected to the tail of the electrocoagulation end, the wire being connected to a radio frequency generator through the electrocoagulation end channel; the electrocoagulation end includes a high-frequency electrocoagulation knife head in air medium and a low-temperature plasma radio frequency knife head in water medium.

[0004] The utility model patent uses a water channel structure that directly connects to external water pipes by opening a water channel groove inside. Therefore, it still suffers from the problem that the water channel structure itself is not flexible enough and its application scenarios are limited. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a water circuit connection mechanism applicable to bipolar electrocoagulation clamps with a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A water circuit connection mechanism for bipolar electrocoagulation clamps includes an inlet pipe and an outlet pipe, and a connecting seat with an internal water passage cavity. The inlet pipe is connected to the water passage cavity. The connecting seat has a through hole, through which a pull rod passes. The outlet pipe is located inside the pull rod. The side wall of the pull rod also has an inlet. The water passage cavity and the outlet pipe are connected through the inlet.

[0007] In the above-mentioned water connection mechanism for bipolar electrocoagulation clamp, at least two sealing rings are also included. The side of the connecting seat is provided with a sealing groove that is recessed into the connecting seat. The sealing ring is accommodated in the sealing groove and is located between the pull rod and the connecting seat. The water inlet is located between the two sealing rings.

[0008] In the above-mentioned water circuit connection mechanism for bipolar electrocoagulation clamp, a gasket is also pressed on the side of the sealing ring, and the gasket is arranged in a one-to-one correspondence with the sealing ring. A retaining spring is also pressed on the surface of the gasket away from the sealing ring, and the retaining spring is arranged in a one-to-one correspondence with the gasket. The pull rod surface is provided with a retaining spring mounting groove, and the retaining spring is embedded in the retaining spring mounting groove.

[0009] In the aforementioned water connection mechanism applied to bipolar electrocoagulation clamps, the centerlines of the gasket, sealing ring, and pull rod coincide with each other.

[0010] In the above-mentioned water connection mechanism applied to bipolar electrocoagulation clamp, the connecting seat is fixedly connected to the outer shell, the pull rod passes through the connecting seat through the through hole and is slidably connected to the connecting seat, and during the sliding process of the pull rod, the water inlet is always located between the two sealing rings.

[0011] In the above-mentioned water connection mechanism for bipolar electrocoagulation clamps, the water inlet pipe is located inside the flexible hose, and a water inlet connector extends from the lower surface of the connector seat. The water inlet connector is sleeved inside the flexible hose and is connected to the water inlet pipe.

[0012] In the above-mentioned water circuit connection mechanism applied to bipolar electrocoagulation clamp, the connecting seat is also provided with a conductive mounting groove for installing conductive springs. One end of the conductive mounting groove passes through the upper surface of the connecting seat, and the other end passes through the side of the connecting seat.

[0013] In the above-mentioned water connection mechanism applied to bipolar electrocoagulation clamp, the bottom surface of the conductive mounting groove is provided with a clamping protrusion, and a corresponding clearance groove is provided above the clamping protrusion, and the conductive spring is pressed on the clamping protrusion.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. The pull rod of this utility model passes through the connecting seat through the through hole, so that the water passage cavity is in a state surrounding the outside of the pull rod. It is connected to the water passage cavity through the water inlet set on the side wall. In this way, the connection between the pull rod and the water passage cavity can be maintained when the pull rod rotates during the operation, thereby expanding the application range.

[0015] 2. The application of this utility model only requires an adaptive structural transformation of the internal structure of the existing bipolar electrocoagulation clamp, without adjusting its overall external structure and shape. The modification cost is low, making it suitable for large-scale promotion and use. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] This embodiment provides a water circuit connection mechanism for bipolar electrocoagulation clamps, combined with... Figure 1-3 As shown, it includes an inlet pipe 1 and an outlet pipe 2, and also includes a connecting seat 101 with an internal water passage cavity 102. The 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 outlet pipe 2 is located inside the pull rod 3. The side wall of the pull rod 3 is also provided with an inlet 104. The water passage cavity 102 and the outlet pipe 2 are connected through the inlet 104.

[0020] During surgery, bipolar electrocoagulation forceps require rotating the lever 3 to rotate the forceps head, thereby enabling surgical operations at different sites on the patient. In this invention, water enters from the inlet pipe 1 into the water-passing cavity 102, then from the water-passing cavity 102 through the inlet 104 into the outlet pipe 2, and finally the outlet pipe 2 delivers the water to the area requiring cooling. The lever 3 of this invention passes through the connecting seat 101 via the through hole 103, ensuring that the water-passing cavity 102 is positioned around the outside of 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.

[0021] like Figure 3 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.

[0022] 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.

[0023] Combination Figure 1 and Figure 3 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.

[0024] 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.

[0025] 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.

[0026] like Figure 3As 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.

[0027] like Figure 1 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.

[0028] 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.

[0029] 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.

[0030] Example 2

[0031] This embodiment provides a water circuit connection mechanism for bipolar electrocoagulation clamps. Its specific structure is largely the same as that in Embodiment 1, except for the arrangement of the connecting seat 101. 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.

[0032] 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.

[0033] 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.

[0034] 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, connector 101, water passage cavity 102, through hole 103, 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, locking protrusion 112, and clearance groove 113, 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.
