Description

Technical Field

[0001] This invention relates to the field of endoscopy technology, and more particularly to endoscopes that can be operated by a single person. Background Technology

[0002] An endoscope is an advanced medical device that integrates an image sensor, optical lens, light source, and mechanical system. It can be flexibly inserted into the body through natural orifices or superficial perforations to directly observe the tissue morphology of body cavities and internal organs, accurately locate lesions, and provide strong support for disease diagnosis and treatment. Common flexible endoscopes include gastroscopes, colonoscopes, and bronchoscopes, which play a crucial role in the medical field.

[0003] The key technical advantages of endoscopes lie in their flexibility and image quality. The flexible, bendable endoscope body can easily adapt to the complex anatomical structures of the human body, reducing patient discomfort. Simultaneously, the introduction of high-definition (HD) and 4K imaging technologies enables flexible endoscopes to provide higher quality and clearer images, helping doctors to more accurately observe lesion details, improving diagnostic accuracy and patient treatment outcomes.

[0004] Existing endoscopes have a clamping channel for use with hemostats or cannulas. However, when the doctor places the endoscope in the appropriate position inside the patient's body, another medical staff member is needed to insert the hemostat into the clamping channel of the endoscope to adjust the insertion length or distance of the hemostat and ensure its stability. Existing endoscopes lack a structure that can both control the extension and retraction of the hemostat and ensure its stability, so two people are required to use them. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a single-person operated endoscope to overcome the above-mentioned shortcomings of the prior art.

[0006] Technical solution: A single-person operated endoscope includes a control unit, a biopsy valve is fixedly installed on the bottom side wall of the control unit, a drive component is provided inside the biopsy valve, a drive mechanism is provided inside the drive component, a biopsy channel is opened at the top of the biopsy valve, an insertion tube is fixedly installed at the bottom of the control unit, a forceps channel is provided on the insertion tube, and the biopsy channel is connected to the forceps channel.

[0007] As a further description of the above technical solution: the top of the driving component is provided with a through groove, the driving mechanism includes two driving wheels, the through groove is disposed between the two driving wheels, a transmission component is disposed between the two driving wheels, a connecting rod is fixedly installed on one of the driving wheels, and a telescopic control knob is fixedly installed on the end of the connecting rod away from the driving wheel.

[0008] As a further description of the above technical solution: the transmission assembly includes two first gears, which are respectively fixedly mounted on the side walls of the two drive wheels. A second gear is rotatably mounted inside the drive component. The second gear is disposed between the two first gears and meshes with the two first gears respectively. The two first gears do not contact each other.

[0009] As a further description of the above technical solution: a movable groove is provided on the outer wall of the biopsy valve, and the driving component slides in conjunction with the movable groove.

[0010] As a further description of the above technical solution: the bottom of the driving component is provided with a toothed groove, the bottom of the driving component is provided with a control disk, the control disk is slidably installed inside the biopsy valve, a spring is fixedly installed between the control disk and the biopsy valve, and the control disk is engaged with the toothed groove.

[0011] As a further description of the above technical solution: both the top of the biopsy channel that connects to the control panel inside the biopsy valve and the top of the control panel are provided with expansion ports, and the expansion ports are conical.

[0012] As a further description of the above technical solution: a universal cable is fixedly connected to the top side wall of the control unit, and a light source connector is fixedly installed at the end of the universal cable away from the control unit. A light guide and an air tube are provided inside the universal cable. The light guide and the air tube are also provided inside the insertion tube. The light guide is made of a quartz lens.

[0013] As a further description of the above technical solution: an angle control knob is rotatably mounted on the top of the control unit, and a remote switch is provided on the top of the control unit.

[0015] Beneficial effects: This invention incorporates a drive mechanism inside the biopsy valve. The drive mechanism, in conjunction with the transmission assembly, drives the hemostat to extend and retract. Furthermore, the distance between the two drive wheels is less than the diameter of the hemostat cable, increasing the positive pressure applied by the drive wheels to the cable and enhancing friction to prevent slippage, thus securing the hemostat. The rotation of the drive mechanism further controls the rotation of the hemostat. Simultaneously, the meshing between the toothed groove and the control disc ensures the stability of the hemostat after rotation, guaranteeing its flexible and stable use on the endoscope and facilitating single-person operation.

[0025] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-6A single-person operated endoscope includes a control unit 1. A biopsy valve 2 is fixedly installed on the bottom side wall of the control unit 1. A drive component 3 is provided inside the biopsy valve 2, and a drive mechanism is provided inside the drive component 3. A biopsy channel 4 is opened at the top of the biopsy valve 2. An insertion tube 5 is fixedly installed at the bottom of the control unit 1. A forceps channel 6 is provided on the insertion tube 5. The biopsy channel 4 is connected to the forceps channel 6. During the use of this device, hemostatic forceps are inserted into the forceps channel 6 of the insertion tube 5 through the biopsy channel 4. The extension and retraction of the hemostatic forceps are controlled by the drive mechanism. The drive mechanism can effectively clamp and fix the hemostatic forceps, keeping them stable inside the endoscope. This allows the use of the hemostatic forceps to be operated by a single person without the need for a second medical staff member.

[0027] As a preferred technical solution of this embodiment, the top of the driving component 3 is provided with a through groove 7. The driving mechanism includes two driving wheels 8. The through groove 7 is disposed between the two driving wheels 8. A transmission component is disposed between the two driving wheels 8. A connecting rod 9 is fixedly installed on one of the driving wheels 8. A telescopic control knob 10 is fixedly installed on the end of the connecting rod 9 away from the driving wheel 8. The hemostat enters the through groove 7 of the driving component 3 through the biopsy channel 4, so that the hemostat is between the two driving wheels 8. The body of the hemostat is made of a special steel wire rope. When the end of the special steel rope reaches the two driving wheels 8, it is at the angle between the two driving wheels 8. At this time, by rotating the telescopic control knob 10, the two driving wheels 8 are driven to rotate, so that the end of the hemostat is driven to continuously enter the channel 6 through the rotational friction between the two driving wheels 8 and the hemostat. When the hemostat reaches the end of the insertion tube 5, it stops moving forward and is hidden inside the insertion tube 5. When needed, it is pushed out by the telescopic control knob 10.

[0028] As a preferred embodiment, the transmission assembly includes two first gears 11, which are respectively fixedly mounted on the sidewalls of the two drive wheels 8. A second gear 12 is rotatably mounted inside the drive component 3, and the second gear 12 is disposed between the two first gears 11. The second gear 12 meshes with the two first gears 11 respectively, and the two first gears 11 do not contact each other. The two first gears 11 are driven by the second gear 12 to ensure that the two first gears 11 rotate in the same direction. The distance between the two drive wheels 8 is less than the diameter of the hemostat cable, which increases the normal pressure applied by the drive wheels 8 to the cable, increases the friction to prevent slippage. The greater the normal pressure, the stronger the friction, and the more reliable the transmission. As a result, there is static friction between the cable and the sidewall of the roller. When the roller rotates, the sidewall "grabs" the cable through friction, driving it to move.

[0029] As a preferred technical solution in this embodiment, a movable groove 13 is provided on the outer wall of the biopsy valve 2, and the driving member 3 slides in the movable groove 13. When using the hemostat, it may be necessary to use the hemostat at a certain angle. The rotation of the telescopic control knob 10 can be used to drive the rotation of the driving member 3. The holding force between the two driving wheels 8 and the hemostat cable makes the hemostat relatively fixed to the driving wheels 8 when the driving wheels 8 do not rotate. Therefore, the rotation of the driving member 3 drives the hemostat cable to rotate, which in turn drives the end of the hemostat to rotate.

[0030] As a preferred technical solution of this embodiment, the bottom of the driving component 3 is provided with a toothed groove 14, and the bottom of the driving component 3 is provided with a control disk 15. The control disk 15 is slidably installed inside the biopsy valve 2, and a spring 16 is fixedly installed between the control disk 15 and the biopsy valve 2. The control disk 15 and the toothed groove 14 are engaged. After the driving component 3 drives the hemostat to rotate, in order to ensure the stability of the hemostat's position, the driving component 3 is fixed by the mutual engagement between the control disk 15 and the toothed groove 14, so as to ensure the stability of the position of the driving component 3 and the hemostat after rotation.

[0031] As a preferred technical solution in this embodiment, both the top of the biopsy channel 4 that connects to the control disk 15 inside the biopsy valve 2 and the top of the control disk 15 are provided with expansion ports 17, which are conical in shape. Since the control disk 15 needs to move inside the biopsy valve 2, the biopsy channel 4 inside the biopsy valve 2 is inevitably discontinuous. Therefore, expansion ports 17 are provided at the discontinuous breaks to facilitate the smooth passage of the hemostatic forceps.

[0032] As a preferred embodiment, a universal cable 18 is fixedly connected to the top sidewall of the control unit 1. A light source connector 19 is fixedly installed at the end of the universal cable 18 away from the control unit 1. A light guide 20 and a trachea 21 are disposed inside the universal cable 18, and the light guide 20 and the trachea 21 are also disposed inside the insertion tube 5. The light guide 20 is made of a quartz lens. The light source connector 19 is the interface for connecting the endoscope to an external light source device. Its main function is to provide stable and uniform illumination for the endoscope, ensuring that the doctor can clearly observe the lesions in the patient's body. The quartz lens light guide 20 is a component in the endoscope used to transmit and focus light. It can focus and guide the light transmitted from the light source connector 19, ensuring that the light can accurately illuminate the observed area and improve the image quality of the endoscope. The trachea 21 may be used in the endoscope to deliver gas, such as to blow away blood or tissue debris in front of the lens to maintain a clear field of vision. In some treatment processes, the trachea 21 can also be used to deliver drugs or perform local anesthesia.

[0033] As a preferred embodiment, an angle control knob 22 is rotatably mounted on the top of the control unit 1, and a remote switch 23 is provided on the top of the control unit 1. The angle control knob 22 controls the rotation angle of the insertion tube 5 end, and the remote switch 23 allows the doctor to control certain functions of the endoscope, such as switching the light source on and off, freezing and thawing the image, while away from the endoscope host. This simplifies the operation process, reduces the number of steps the doctor takes during surgery, and improves surgical efficiency. The above structure has already been applied in existing endoscopes and will not be described in detail here.

[0034] Example 2

The output end of the micro motor 25 is fixedly connected to the drive wheel 8. With the corresponding motor drive module, the computer can control the micro motor through the micro controller as a bridge. By setting values ​​in advance on the computer, the computer can control the automatic extension and retraction of the hemostat and its positioning.
