Description

Technical Field

[0001] The utility model relates to the technical field of endoscope cameras, and particularly relates to an endoscope camera adapter. Background Technique

[0002] An endoscope is used to observe the internal state or collect tissue cells of a diseased part in the body. It is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc. Inside the endoscope, there are disposal tool insertion channels or air supply pipelines, water supply pipelines, suction pipelines, etc.; the endoscope can enter the stomach through the oral cavity or enter the body through other natural orifices. Using the endoscope, lesions that cannot be shown by X-rays can be seen.

[0003] Currently, in endoscopic surgery, the connection between the endoscope and the imaging system is through the bayonet of the camera. Before the operation, the doctor will disinfect and sterilize the camera and the endoscope; sometimes, the doctor needs to use different endoscopes in one operation and will also disinfect and sterilize the required endoscopes in advance. However, there is only one camera. During the operation, different endoscopes need to be replaced. In this case, although the camera and the endoscope are disinfected and sterilized before the operation, there is still a possibility of cross-infection at the camera end when different endoscopes are replaced during the operation.

[0004] The imaging system is expensive, and it is too costly to configure multiple sets of imaging systems and thus cannot be achieved. Therefore, there is still a situation where one operating room or multiple operating rooms share one imaging system. Moreover, the sterilization and disinfection of the camera takes a relatively long time, seriously affecting work efficiency.

[0005] Endoscopes are relatively inexpensive and are used more frequently in patient surgeries. Hospitals will also be equipped with more endoscopes for replacement; usually, the doctor will use a disposable sterile cover to protect the camera and replace the endoscope according to the needs of the patient's surgery. The endoscope in contact with the patient has been disinfected and sterilized. However, since the endoscope is used by being stuck on the camera and only the endoscope is replaced without replacing the camera, there is also a possibility of cross-infection between different patients.

[0006] Therefore, based on the above problems, an endoscope camera adapter is proposed to conveniently and quickly replace the contaminated endoscope during the operation. Content of the Utility Model

[0007] The purpose of the utility model is to provide an endoscope camera adapter to solve the problems raised in the above background technique.

[0008] To achieve the above object, the present utility model provides the following technical solutions: An endoscope camera adapter, including an endoscope, one end of the endoscope is provided with a threaded adapter device, the inner wall of the adapter device is fixedly provided with a clamping device, and one side of the endoscope is provided with a threaded extension ring;

[0009] The adapter device includes a connecting shaft threadedly installed at one end of the endoscope. One end of the connecting shaft is fixedly provided with a connecting ring. The outer wall of the connecting shaft is fixedly provided with a limiting plate. The outer wall of the connecting shaft close to the endoscope is fixedly provided with a limiting ring. A limiting groove is provided between the limiting ring and the limiting plate. A transfer ring is movably arranged in the limiting groove;

[0010] The clamping device includes a clamping shaft fixedly installed on the inner wall of the connecting shaft. Clamping grooves are symmetrically arranged on both sides of the clamping shaft. A clamping plate is movably arranged in the clamping groove. One end of the inner wall of the clamping groove is fixedly provided with a damping spring. One end of the damping spring is fixedly connected to the clamping plate. One side of the clamping plate is fixedly provided with a clamping rod. One side of the clamping rod is fixedly provided with a limiting rod. One end of the clamping plate is fixedly provided with a driven plate. A gear is adaptively arranged on one side of the driven plate. A driving plate is adaptively arranged on the other side of the gear. One end of the driving plate is fixedly provided with a pressing rod.

[0011] Further, ejector rods are symmetrically arranged on one side of the clamping shaft, and the ejector rods are adapted to one end of the endoscope.

[0012] Further, the clamping rod is in clamping and adaptive connection with the endoscope, and the limiting rod is adapted to one end of the endoscope.

[0013] Further, the connecting ring is connected to the camera.

[0014] Further, a sealing cover is provided with threads on the surface of the adapter device.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] (1) In order to meet the need for convenient and rapid replacement of a contaminated endoscope during the operation, during use, one end of the endoscope is clamped and installed in the clamping rod, so that the clamping rod clamps and fixes one end of the endoscope, and the position of the endoscope is restricted by the limiting rod to prevent the endoscope from moving during use;

[0017] When the device needs to be disassembled, it is only necessary to apply pressure to the pressing rod to move the pressing rod, so that the movement of the pressing rod pushes the active plate to move, so that the tooth groove on one side of the active plate pushes the gear to rotate, and the rotation of the gear drives the driven plate on the other side to move up and down, so that the driven plate and the active plate operate in the opposite direction, and the driven plate drives the card-embedded plate to move up and down during the up and down movement, so that the card-embedded plate drives the card-embedded rod to move, so that the card-embedded rod cancels the position restriction on one end of the endoscope, and at the same time, the elastic restoring force of the damping spring itself can drive the card-embedded plate to reset, so that the card-embedded plate always applies pressure to one end of the endoscope through the card-embedded rod to fix it when in use, and the position of the endoscope is further restricted by the push rod.

[0018] (2) When the traditional endoscope is used, the traditional light guide has a high risk of falling off during use. Therefore, when in use, the light guide is placed on the surface of the extension ring to fix the light guide, prevent the light guide from falling off during the operation and prevent the light guide from being contaminated during the operation.

A limiting plate 203 is fixedly provided on the outer wall of the connecting shaft 201, and a limiting ring 204 is fixedly provided on the outer wall of the connecting shaft 201 close to the endoscope 1. A limiting groove 205 is provided between the limiting ring 204 and the limiting plate 203, and a middle transfer ring 206 is movably provided in the limiting groove 205. A sealing cover 6 is threadedly provided on the surface of the adapter device 2, which can threadedly connect the sealing cover 6 to the surface of the adapter device 2 when the device is not in use to seal the adapter device 2 and prevent the inner wall of the adapter device 2 from being contaminated. When in use, the sealing cover 6 is rotated threadedly to separate the sealing cover 6 from the adapter device 2 for easy use of the device. A clamping device 3 is fixedly provided on the inner wall of the adapter device 2. The clamping device 3 includes a clamping shaft 301 fixedly installed on the inner wall of the connecting shaft 201. Clamping grooves 302 are symmetrically provided on both sides of the clamping shaft 301. Clamping plates 303 are movably provided in the clamping grooves 302. One end of the inner wall of the clamping groove 302 is fixedly provided with a damping spring 304, and one end of the damping spring 304 is fixedly connected to the clamping plate 303. A clamping rod 305 is fixedly provided on one side of the clamping plate 303, a limiting rod 306 is fixedly provided on one side of the clamping rod 305, and a driven plate 307 is fixedly provided at one end of the clamping plate 303. A gear 308 is adaptively provided on one side of the driven plate 307, and a driving plate 309 is adaptively provided on the other side of the gear 308. A pressing rod 310 is fixedly provided at one end of the driving plate 309. An extension ring 4 is threadedly provided on one side of the endoscope 1. Thrust rods 5 are symmetrically provided on one side of the clamping shaft 301. The thrust rods 5 are adapted to one end of the endoscope 1. The clamping rod 305 is adaptively connected to the endoscope 1 in a clamping manner, and the limiting rod 306 is adapted to one end of the endoscope 1;

[0028] The specific implementation method is as follows:

[0029] During use, one end of the endoscope 1 is clamped and installed inside the clamping rod 305, so that the clamping rod 305 clamps and fixes one end of the endoscope 1, and the position of the endoscope 1 is restricted by the limiting rod 306 to prevent the endoscope 1 from moving during use;

[0030] When the device needs to be disassembled, only pressure needs to be applied to the pressing rod 310 to move the pressing rod 310. The movement of the pressing rod 310 pushes the active plate 309 to move. The tooth groove on one side of the active plate 309 drives the gear 308 to rotate. The rotation of the gear 308 drives the driven plate 307 on the other side to move up and down, so that the driven plate 307 moves in the opposite direction to the active plate 309. During the up and down movement of the driven plate 307, the clamping plate 303 is driven to move up and down, so that the clamping plate 303 drives the clamping rod 305 to move, and the clamping rod 305 cancels the position restriction on one end of the endoscope 1. At the same time, the elastic restoring force of the damping spring 304 can drive the clamping plate 303 to reset, so that the clamping plate 303 always applies pressure to one end of the endoscope 1 through the clamping rod 305 for fixation during use, and further restricts the position of the endoscope 1 through the ejector rod 5.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
