Description

[0001] The present invention relates to the technical field of medical instruments, and in particular to an electrode clamp cooling system and an electrode clamp for rotating a clamp head at any axial angle. Background Art

[0002] Energy medical devices are primarily used in electrosurgery for tissue cutting and sealing blood vessels or tissues. Heat diffusion at the electrode's occluded location can cause thermal damage to adjacent or surrounding tissues, a critical issue that needs to be addressed during current clinical procedures.

[0003] Surgical electrode forceps are a commonly used energy-based medical device. They include a pair of jaws that can be controlled to open and close to grasp the target tissue between them. The jaws are brought into close proximity to apply a mechanical clamping force to the tissue, while electrosurgical energy is transferred to the tissue through one or more electrode surfaces of the jaws, enabling electrosurgical cutting and coagulation. To facilitate surgical procedures, surgical electrode forceps require that the forceps head be capable of rotating 360 degrees axially and circumferentially along the electrode shaft. However, achieving cooling and heat dissipation in the forceps head region has been challenging for forceps with such arbitrarily rotatable heads. The technical solutions disclosed in the prior art are unable to achieve the required waterway sealing while ensuring unrestricted axial rotation of the forceps head. Therefore, those skilled in the art are in urgent need of a new electrode forceps cooling system that can meet the cooling and heat dissipation requirements of the forceps head region for forceps with arbitrarily axial rotation of the forceps head.

[0020] The above-mentioned electrode clamp cooling system for the clamp head to rotate at any axial angle; and the clamp head assembly, the clamp head conductive assembly and the insulating rotary wheel.

[0021] The technical solution of the present invention has the following advantages:

[0022] 1. The present invention provides an electrode clamp cooling system for rotating the clamp head at any axial angle, the electrode clamp comprising:

[0023] The clamp head assembly comprises: a movable clamping body and a static clamping body which are hingedly connected; the clamp head assembly has a clamp head heat exchange cavity for cooling medium to pass through;

[0024] The pliers head conductive assembly comprises: a metal outer tube, and a conductive pull rod driven to extend and retract within the metal outer tube; the metal outer tube is conductively and fixedly connected to the static clamping body, and the conductive pull rod is conductively and fixedly connected to the dynamic clamping body, and drives the dynamic clamping body to complete the clamping and opening actions of the pliers head assembly;

[0027] First, in order to achieve the 360-degree rotation of the pliers head in its axial direction and circumferentially along the length of the pliers head, the present invention uses an insulating rotating wheel mounted on the metal outer tube to drive the pliers head conductive component to rotate at any angle along its circumferential direction, thereby driving the pliers head assembly to achieve 360-degree rotation. This structure can effectively achieve the requirement of 360-degree rotation of the pliers head assembly in the circumferential direction along the length of the pliers head.

[0028] More importantly, in order to solve the problem of cooling and dissipating heat in the clamp head area of ​​the electrode clamp, the present invention also specifically discloses that: a clamp head heat exchange cavity for passing a cooling medium is provided in the clamp head assembly. An electrode clamp cooling system is also provided. The sealing bracket of the electrode clamp cooling system is sleeved on the electrode clamp main shaft. During the process of the electrode clamp main shaft rotating along with the clamp head conductive assembly and the clamp head assembly, the sealing bracket remains stationary relative to the electrode clamp main shaft, thereby achieving unlimited axial rotation of the electrode clamp main shaft, while the cooling cavity remains sealed. The above-mentioned sealing bracket and the electrode clamp main shaft form a cooling cavity for accommodating the cooling medium. The circulating water circuit of the electrode clamp cooling system provides cooling medium to the cooling cavity. The cooling cavity is connected to the clamp head heat exchange cavity. The electrode clamp main shaft can rotate freely under the drive of the insulating rotary wheel, and drives the clamp head assembly to rotate freely, thereby solving the problem of cooling and dissipating heat in the clamp head area of ​​the electrode clamp that can rotate at any angle of 360 degrees in the circumference of the present invention.

[0029] 2. In the electrode clamp cooling system provided by the present invention, which allows the clamp head to rotate at any angle along the axis, the clamp head heat exchange cavity is disposed within the static clamping body. In the present invention, the clamp head heat exchange cavity can be disposed within either or both of the dynamic clamping body, as needed. However, considering production costs and optimizing spatial layout, disposing the clamp head heat exchange cavity within the static clamping body is preferred.

[0031] In the present invention, the cooling chamber consists of a liquid inlet cavity and a liquid discharge cavity. The liquid inlet pipe of the circulating water circuit is connected to the liquid inlet cavity, and the liquid discharge pipe of the circulating water circuit is connected to the liquid discharge cavity. Subsequently, the liquid inlet cavity and the liquid discharge cavity are connected to the aforementioned clamp head heat exchange cavity through a coolant conduit, thereby circulating the coolant in the clamp head heat exchange cavity and ensuring effective cooling and heat dissipation in the clamp head area.

Furthermore, each groove sidewall is provided with a channel for a coolant conduit. These coolant conduits, which rotate synchronously with the electrode clamp spindle and the clamp head assembly, allow stable and reliable circulation of coolant within the clamp head heat exchange cavity, ensuring effective cooling and heat dissipation of the clamp head area.

The present invention provides an electrode clamp cooling system for rotating the clamp head at any axial angle, wherein an annular boss is provided on the main shaft of the electrode clamp; there are two sealing brackets, which are respectively provided on both sides of the annular boss of the main shaft of the electrode clamp to form the liquid inlet cavity and the liquid discharge cavity respectively.

[0036] In the present invention, the annular boss divides the liquid inlet and liquid outlet cavities into two sections, each corresponding to a separate sealing bracket. The two sealing brackets are respectively adapted to the electrode clamp main shaft and remain stationary during the rotation of the electrode clamp main shaft, forming the liquid inlet and liquid outlet cavities, respectively. This structure effectively ensures stable and reliable operation of the electrode clamp cooling system.

[0037] 6. The present invention provides an electrode clamp cooling system for rotating the clamp head at any axial angle, and dynamic sealing rings are provided on the connecting surface of the sealing bracket and the main shaft of the electrode clamp, respectively located at the two ends of the length direction of the liquid inlet cavity and the liquid discharge cavity.

[0038] In the present invention, the dynamic sealing ring can effectively seal the relatively rotating sealing bracket and the connecting surface of the electrode clamp main shaft, thereby ensuring the stability and reliability of the equipment.

[0039] 7. The present invention provides an electrode clamp cooling system for rotating the clamp head at any axial angle. A pipeline support is provided on the sealing bracket. The shape of the pipeline support is respectively adapted to the liquid inlet pipe and the liquid discharge pipe, and is suitable for fixing the circulating water circuit and turning it to extend into the cooling chamber.
