Description

Technical Field

[0001] This invention relates to the field of rigid lens technology, and more particularly to a video rigid lens that is easy to use. Background Technology

[0002] Currently available medical devices for assisting intubation include fiber optic laryngoscopes, video laryngoscopes, and rigid video endoscopes, as well as light wands. However, all have some drawbacks. For example, with video laryngoscopes, a guidewire must be used to fix the endotracheal tube into a specific curved shape before intubation, and the mouth opening is relatively large. Rigid video endoscopes can compensate for the shortcomings of video laryngoscopes, but sterilization of the endoscope body is currently a problem. Many manufacturers only offer wiping sterilization, not immersion sterilization. The rotation range of the display screen in existing rigid video endoscopes is limited, failing to meet the operator's needs for adjusting the screen angle. The endoscopes are relatively long, and the self-locking mechanisms currently available on the market have large gaps, resulting in significant wobbling, which is even more pronounced with longer rigid video endoscopes. This is detrimental to intubation and, due to the significant wobbling, can easily cause poor contact.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a video hard lens that is easy to use, allows for repeated use of the video hard lens, facilitates the operator's requirements for the angle of the display screen, avoids shaking between the lens body and the handle, and avoids poor contact.

[0005] The technical solution of this invention is as follows: A convenient video rigid endoscope is provided, comprising: a display screen, a handle connected to the display screen, an endoscope body connected to the handle, and a disposable tracheal connector fitted onto the endoscope body. The disposable tracheal connector comprises: a connector body and a transparent flexible tube sleeve. The connector body is provided with an insertion hole, a tracheal insertion groove, and an extension tube. The transparent flexible tube sleeve passes through the tracheal insertion groove and communicates with the insertion hole. The transparent flexible tube sleeve separates the insertion hole and the tracheal insertion groove. The extension tube communicates with the tracheal insertion groove. The endoscope body is inserted into the transparent flexible tube sleeve through the insertion hole. The endoscope body can be inserted through the insertion hole into the transparent flexible tube sleeve, so that the surface of the endoscope body is covered by the transparent flexible tube sleeve. During intubation, direct contact between the endoscope body and the human body is avoided. After use, this disposable tracheal connector can be discarded without disassembling the endoscope body for soaking and disinfection. This will greatly reduce the cost of intubation surgery and greatly facilitate its application. The material of the transparent flexible tube sleeve is preferably polycarbonate.

[0006] The user-friendly video rigid mirror further includes a dual-axis rotating frame; the dual-axis rotating frame includes a horizontal rotating axis and a vertical rotating axis connected to the horizontal rotating axis. The horizontal rotating axis is connected to the display screen, and the vertical rotating axis is connected to a handle. The display screen is connected to the handle via the dual-axis rotating frame, allowing for a wide range of adjustable angles, making it convenient for operators.

[0007] The horizontal pivot includes: a horizontal pivot body and at least one damping pivot. The horizontal pivot body is provided with a first pivot hole, and the display screen is provided with a second pivot hole. The two ends of the damping pivot are respectively inserted into the first pivot hole and the second pivot hole. The damping pivot can stop the display screen at any position without deviation, which is convenient for operators.

[0008] The damping shaft can be structured in two ways. The first method includes a shaft body and a compression spring. The shaft body comprises a round rod and a fixed rod connected to the round rod. The fixed rod has a first spring groove, and a spring support plate is provided in the first shaft hole. The two ends of the compression spring abut against the first spring groove and the spring support plate, respectively. The second shaft hole is a round hole, and the round rod is inserted into it. The fixed rod is a non-round rod, and the first shaft hole is also non-round, with the fixed rod inserted into it. The damping shaft further includes a first damping ring fitted onto the round rod, positioned between the fixed rod and the display screen. The first damping ring enhances the damping effect of the damping shaft.

[0009] The second type is as follows: the damping shaft includes a first damping element and a second damping element. The first damping element is provided with a damping circular hole, and the second damping element is provided with a damping arc-shaped plate. The damping arc-shaped plate is inserted into the damping circular hole and abuts against the inner wall of the damping circular hole. The first damping element is inserted into the first shaft hole and is locked by the first shaft hole, and the second damping element is inserted into the second shaft hole and is locked by the second shaft hole.

[0010] The vertical shaft includes: a vertical shaft body, a spring plate, and a vertical shaft connector. The vertical shaft connector includes: a support cylinder and a connecting plate connected to the support cylinder. The support cylinder has a vertical circular groove, and the vertical shaft body has a spring plate groove. The vertical shaft body is inserted into the vertical circular groove, and the spring plate abuts against the inner walls of the spring plate groove and the vertical circular groove, respectively. The connecting plate is connected to the handle. Because the spring plate abuts against the inner walls of the spring plate groove and the vertical circular groove, it can restrain the vertical shaft body, preventing easy movement of the vertical shaft and facilitating operation.

[0011] The vertical shaft further includes a second damping ring fitted onto the vertical shaft body, the second damping ring contacting both the vertical shaft body and the inner wall of the vertical circular groove. The second damping ring enhances the friction between the vertical shaft body and the vertical circular groove, thereby improving the damping effect.

[0012] The vertical rotating shaft further includes a limiting plate, which is connected to the vertical shaft body and spans the vertical circular groove. A connecting plate is disposed between the limiting plate and the support cylinder. The limiting plate prevents the vertical shaft body from coming out of the vertical circular groove.

[0013] The handle is connected to the lens body via a connecting seat, a connecting head, and a self-locking mechanism. The self-locking mechanism includes a pin, a trigger, and a pressing spring. The trigger includes a pressing section, a connecting strip connected to the pressing section, and a hook connected to the connecting strip. The connecting strip has a first pin hole located between the pressing section and the hook. The connecting seat has a second pin hole, a spring support strip, a pressing hole, a trigger movable groove, and a slot. The second pin hole passes through the trigger movable groove, and the slot communicates with the trigger movable groove. The pressing hole communicates with the trigger movable slot; the two ends of the pressing spring abut against the pressing section and the spring support bar respectively; the pressing section is disposed in the pressing hole; the connecting bar is disposed in the trigger movable slot; the pin passes through the first pin hole and the second pin hole; the connector includes: a plug, a rear end connected to the plug, and an O-ring fitted on the plug; the plug is provided with a groove; the plug matches the slot; the groove matches the hook; and the O-ring is disposed between the groove and the rear end.

[0014] The connector connects to the handle, and the connector head connects to the lens body. The trigger can be configured as a lever structure with a pin as its axis. After the plug is inserted into the slot, the hook will lock into the groove, thus locking the connector and connector head together. The O-ring, made of elastic rubber, plastic, or silicone, effectively fills the gap between the slot and the plug, perfectly preventing any wobbling between the connector and connector head for easy application. To remove the connector, press the pressing section. Due to the lever's action, the latch will also lift out of the groove, disengaging the hook from the groove. The hook is no longer locked in the groove, and then the plug can be pulled out, thus separating the connector from the connector head.

[0015] The spring support bar has a second spring groove, and the pressing section has a third spring groove. Both ends of the pressing spring are inserted into the second and third spring grooves, respectively. The self-locking mechanism further includes a push pin, which is disposed in the third spring groove. The pressing spring abuts against the pressing section via the push pin. The push pin allows the force of the pressing spring to be applied more evenly to the pressing section. The second and third spring grooves facilitate the assembly of the pressing spring and prevent its position from shifting.

[0016] The slot is provided with a foolproof strip, and the plug is provided with a foolproof groove. The foolproof strip matches the foolproof groove to ensure that the plug and the slot are aligned and installed to avoid incorrect installation. The front end of the hook and the front end of the plug are both arc surfaces. The arc surfaces can make it easier for the plug to push up the hook when it is inserted into the slot.

[0017] Using the above solution, the present invention provides a convenient video rigid endoscope. The endoscope body can be inserted through the insertion hole into a transparent flexible tube sleeve, so that the surface of the endoscope body is covered with a transparent flexible tube sleeve. When inserting the tube, the endoscope body avoids direct contact with the human body. After use, this disposable tracheal connector can be discarded without disassembling the endoscope body for soaking and disinfection. This will greatly reduce the cost of intubation surgery and greatly facilitate its application. Attached Figure Description

The spring plate 34 abuts against the inner walls of the spring plate groove 38 and the vertical circular groove 37, respectively. The connecting plate 36 is connected to the handle 11. Because the spring plate 34 abuts against the inner walls of the spring plate groove 38 and the vertical circular groove 37, the spring plate 34 can restrain the vertical shaft body 33, preventing the vertical shaft from moving easily and facilitating operation.

[0041] The vertical shaft further includes a second damping ring 39 fitted onto the vertical shaft body 33. The second damping ring 39 contacts both the vertical shaft body 33 and the inner wall of the vertical circular groove 37.
