AI Technical Summary
During the use of existing laparoscopic instruments, fluids outside the instrument structure can easily leak into the interior, leading to contamination of the internal fiber optic channels and components, which affects surgical outcomes and equipment lifespan.
A laparoscopic handle structure was designed, which uses a combination of sealing rings and sealing gaskets to ensure the sealing between the connector and the housing. Sealing rings and sealing gaskets are set in key parts to form a sealed cavity to prevent fluid leakage.
It effectively prevents fluid contamination of internal components of the handle, ensures the cleanliness of the fiber optic channel, improves the sealing performance of the handle, extends equipment life, and reduces the risk of contamination.

Abstract
Claims
1. A laparoscopic handle seal structure, characterized by: The device includes a housing with an internal cavity containing a PCB board. A control button is located on the housing relative to the PCB board. Connectors are installed at the front and rear ends of the housing. The connectors have axially extending channels for fiber optic and signal lines, which are connected to the cavity. A sealing ring is provided between the outer side of the connector and the housing to make the cavity a sealed chamber. The surface of the control button is covered with a sealing gasket, which is installed on the housing.
2. The laparoscopic handle seal structure of claim 1, wherein: The front and rear ends of the housing are detachably fitted with end caps. The end caps are provided with through holes for installing connectors. Sealing rings are provided between the end caps and the housing, and between the connectors and the through holes.
3. The laparoscopic handle seal structure of claim 2, wherein: The outer side of the end cap is provided with a mounting groove for installing a sealing ring.
4. The laparoscopic handle seal structure of claim 1, wherein: The connector has a stepped structure at one end near the housing. The right-angle bend of the stepped structure abuts against the housing, and the sealing ring is fitted onto the right-angle bend of the stepped structure on the connector.
5. The laparoscopic handle seal structure of claim 1, wherein: A fixing frame is provided along the axial position inside the cavity, and the PCB board is mounted on the fixing frame.
6. The laparoscopic handle seal structure of claim 5, wherein: The mounting bracket or PCB board is equipped with wire clamps.
7. The laparoscopic handle sealing structure as described in claim 1, characterized in that: The top of the housing has a recess, and the control button and the sealing gasket are located inside the recess. The sealing gasket and the housing are fixed together with fasteners.
8. A laparoscope characterized by: The laparoscope includes an optical fiber plug and a laparoscope handle sealing structure as described in any one of claims 1 to 7. The laparoscope handle sealing structure and the optical fiber plug are connected by a cable. The cable contains an optical fiber and a signal line. The optical fiber plug includes a connector. The connector has a channel for the optical fiber and signal line to pass through. The surface of the connector has several interfaces that communicate with the channel. One interface is sealed with a plug, and the other interfaces are sealed with connectors. The plug and connectors have through holes for the signal line or optical fiber to pass through.
9. The laparoscope of claim 8, wherein: The connector is fitted with a cover at the interface of the plug, and the cover is sealed to the plug. A sealing ring is provided between the outer side of the cover and the connector.
10. The laparoscope of claim 8, wherein: It also includes a monitor, which is connected to the fiber optic cable and signal line of the fiber optic plug, and the front end of the fiber optic cable extending out of the housing is connected to the camera.
