Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, specifically to a clamping cap with an electric knife tip fixing device. Background Technology

[0002] A high-frequency electrosurgical unit (HFOS) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue by generating a high-frequency, high-voltage current at the tip of its effective electrode, achieving tissue separation and coagulation, thus achieving cutting and hemostasis. Currently, when using an HFOS to cut tissue during surgery, it enters through the instrument channel of an endoscope. Because its outer diameter is smaller than the instrument channel, it cannot be fixed in place during the cutting process and may wobble, potentially leading to failure to cut the target tissue and affecting the surgical progress. Utility Model Content

[0003] Technical objective: To address the shortcomings of existing high-frequency electrosurgical procedures, this utility model discloses a clamping cap with an electrosurgical tip fixing device.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A clamping cap with an electrosurgical tip fixing device is provided. The clamping cap is fixed to an endoscope lens and includes a clamping cap housing. The fixing device includes a thin film layer that is detachably fixed inside the clamping cap housing. The thin film layer has a lens hole corresponding to the endoscope lens and an instrument hole corresponding to the instrument channel. A limiting sleeve that matches the shape of the electrosurgical tip is provided at the instrument hole, and the electrosurgical tip is fixed by the limiting sleeve.

[0006] Preferably, the limiting sleeve of this utility model adopts a conical structure, and the diameter of the end of the limiting sleeve is between the minimum diameter and the maximum diameter of the electric knife head. The extension distance of the electric knife head is controlled by changing the diameter of the end of the limiting sleeve.

[0007] Preferably, the inner wall of the clamping cap housing of this utility model is provided with a slot for clamping and fixing the film layer. The film layer is inserted along the opening side of the clamping cap housing, and the edge is screwed into the slot by rotation.

[0008] Preferably, the present invention provides a guide structure inside the clamping cap housing along the insertion direction of the film layer to restrict the initial orientation of the film layer insertion.

[0009] Preferably, the guide structure of this utility model includes a guide block disposed on the clamping cap housing, and a notch corresponding to the guide block is disposed on the thin film layer.

[0010] Beneficial effects: The clamping cap with an electrosurgical head fixing device provided by this utility model can limit and fix the high-frequency electrosurgical head through the set limiting sleeve, preventing the head from shaking during surgery; and the thin film layer is detachably connected to the clamping cap shell, which can be flexibly replaced as needed. The extension length of the high-frequency electrosurgical head can be controlled by changing the diameter of the end of the limiting sleeve. Attached Figure Description

[0017] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0018] like Figures 1-4 As shown, this utility model discloses a clamping cap with an electrosurgical head fixing device. The clamping cap 1 is fixed at the endoscope lens and includes a clamping cap housing 2. The fixing device includes a thin film layer 3 that is detachably fixed inside the clamping cap housing 2. The thin film layer 3 has a lens hole 4 corresponding to the endoscope lens and an instrument hole corresponding to the instrument channel. A limiting sleeve 6 that matches the shape of the electrosurgical head 5 is provided at the instrument hole. The electrosurgical head 5 is fixed by the limiting sleeve 6.

[0019] The limiting sleeve 6 of this utility model adopts a conical structure. After the electric knife head 5 is installed, the inner wall of the limiting sleeve 6 abuts against the side wall of the electric knife head 5, thereby achieving reliable fixation of the electric knife head 5. The diameter of the end of the limiting sleeve 6 is between the minimum diameter and the maximum diameter of the electric knife head 5. The extension distance of the electric knife head 5 can be controlled by changing the diameter of the end of the limiting sleeve 6. The film layer 3 is set to be detachable to facilitate disassembly and replacement.

[0020] In one specific embodiment, such as Figure 3 and Figure 4 As shown, the inner wall of the clamping cap housing 2 of this utility model is provided with a slot 7 for clamping and fixing the film layer 3. The film layer 3 is inserted along the opening side of the clamping cap housing 2, and the edge is screwed into the slot 7 by rotation. Inside the clamping cap housing 2, along the insertion direction of the film layer 3, a guide structure is provided to limit the initial orientation of the film layer 3. The guide structure includes a guide block 8 provided on the clamping cap housing 2, and a notch 9 corresponding to the guide block 8 is provided on the film layer 3. The guide block 8 can also limit the film layer 3 after rotation.

[0021] In use, the clamp cap is installed and fixed on the lens of the endoscope. After the electrosurgical head 5 enters through the instrument channel of the endoscope, the limiting sleeve 6 quickly and effectively fixes the electrosurgical head 5 to avoid problems caused by shaking during the operation.
