Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endoscopic instrument auxiliary device and an endoscope. Background Technology

[0002] With the development of science and technology, endoscopes are increasingly used in modern minimally invasive surgery. They can enter the stomach through the mouth or other natural orifices. An endoscope includes an operating section and an insertion section. The insertion section includes an insertion tube and a tip. The tip connects to a curved section at the front end of the insertion tube, and the rear end of the insertion tube connects to the operating section. The tip is equipped with a camera unit, an illumination unit, a working forceps channel, and a water vapor channel. Instruments can be extended through the working forceps channel to the front of the tip for sampling or treatment of lesions.

[0003] Patent document US20030040657A1 discloses an endoscope with a swing bracket in its instrument channel. Near a distal opening, the distal portion of an instrument, extended from the distal opening, passes through the instrument channel, allowing the swing bracket to swing freely. The swing bracket is manipulated by pulling a tilting line proximally. Therefore, based on the swing bracket, the distal portion of the instrument can be controlled to swing near the center of the field of view in both right and left directions from the endoscope. This endoscope allows for the capture of lesion locations within the field of view, facilitating the removal of diseased mucosa.

[0004] However, in practical applications, it has been found that because the swing bracket is located inside the appliance channel, it is difficult to control the appliance to swing at a large angle, and the swing bracket is also difficult to clean. Summary of the Invention

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] The following is combined Figures 1-8This invention describes an endoscopic instrument auxiliary device and an endoscope.

[0039] like Figure 1 and Figure 4 As shown, this embodiment provides an endoscopic instrument auxiliary device, including: a mounting base 100, a lifting clamp component, and a driving assembly 300.

[0040] Mounting base 100 is used to connect to the tip 500 of an endoscope; lifting clamp component is connected to mounting base 100, and drive assembly 300 is connected to lifting clamp component to control lifting clamp component to switch between a first state and a second state.

[0041] With the clamping component in the first state, the vertical projection of the clamping component on the front end face 52 of the tip 500 is misaligned with the area where the clamp passage outlet 51 of the tip 500 is located. At this time, the instrument 400 extends through the clamp passage outlet 51 to the front side of the tip 500, and the clamping component and the instrument 400 separate from each other, so that the instrument 400 is in a naturally extended state on the front side of the tip 500 and is in the initial position.

[0042] When the clamp lifting member is in the second state, the vertical projection of the front end face 52 of the clamp lifting member 500 at least partially overlaps with the area where the clamp outlet 51 is located, so that the clamp lifting member abuts against the instrument 400 extending from the clamp outlet 51. At this time, based on the abutment action of the clamp lifting member against the instrument 400 extending from the clamp outlet 51, the instrument 400 extending from the clamp outlet 51 can swing relative to its initial position. Obviously, when the clamp lifting member returns from the second state to the first state, the instrument 400 extending from the clamp outlet 51 returns to its initial position.

[0043] Specifically, in this embodiment, after the mounting base 100 is installed on the tip 500 of the endoscope, since the lifting forceps component is located on the mounting base 100 and switches between the first state and the second state under the drive of the drive component 300, the instrument 400 extending out of the working forceps channel can be controlled to swing at a relatively large angle based on the state switching of the lifting forceps component outside the working forceps channel. While the auxiliary instrument 400 is sampling or treating the lesion, it is also convenient to clean the lifting forceps component.

[0044] Here, the endoscopic instrument 400 auxiliary device shown in this embodiment is particularly suitable for direct-viewing endoscopes with a viewing angle of 0°.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the mounting base 100 in this embodiment includes a second connecting part 101 and a protective part 102.

[0046] The second connecting part 101 is connected to the protective part 102. The second connecting part 101 is detachably connected to the side wall of the tip 500. The protective part 102 is provided on the front side of the tip 500 along the axial direction of the tip 500.

[0047] At least a portion of the protective part 102 extends circumferentially along the tip 500 to form a protective space inside the protective part 102. The lifting clamp component is disposed in the protective space and connected to the inner wall surface of the protective part 102.

[0048] In this embodiment, the mounting base 100 can be an annular member with a central angle greater than 180° and capable of elastic deformation. For example, the mounting base 100 can be an annular member with an opening on the side, or it can be an annular member with a fully enclosed side.

[0049] In some examples, the inner diameter of the annular member is smaller than the outer diameter of the tip 500, and the second connecting portion 101 on the annular member can be assembled to the side wall of the tip 500 after deformation.

[0050] Meanwhile, the protective part 102 on the annular component is used to cover the lifting clamp component, so that the lifting clamp component does not directly contact the inner wall of the body's natural cavity, thus protecting the mucosa.

[0051] Each edge of the protective part 102 is provided with a rounded chamfer so that the protective part 102 will not cut human tissue during insertion.

[0052] In some embodiments, such as Figure 2 and Figure 3 As shown, the lifting clamp component includes a second deflection block 201, and the first end of the second deflection block 201 is rotatably connected to the inner wall surface of the protection part 102 via an adapter shaft.

[0053] The drive component 300 is connected to the second end of the second deflection block 201 and drives the second deflection block 201 to deflect relative to the mounting base 100 so that the second deflection block 201 switches between a first state and a second state.

[0054] Thus, when the second deflection block 201 is in the first state, the side of the second deflection block 201 facing the central axis of the tip 500 is separated from the instrument 400 extending from the clamp outlet 51. When the second deflection block 201 is in the second state, the second deflection block 201 abuts against the instrument 400 extending from the clamp outlet 51 in the upward direction of the endoscope, so that the instrument 400 extending from the clamp outlet 51 is deflected toward the side of the camera module on the tip 500.

[0055] The upward direction of the endoscope usually refers to the extension direction of the tip 500 from the channel outlet 51 to the camera module.

[0056] In order to better control the contact state between the second deflection block 201 and the appliance 400, this embodiment provides a first groove on one side of the second deflection block 201 facing the tip 500. The first groove is used to fit with the side wall of the appliance 400.

[0057] In some embodiments, in order to better control the deflection of the instrument 400 extending from the clamp outlet 51, the first end of the second deflection block 201 may be positioned close to the front end face of the tip 500, and the second end of the second deflection block 201 may be positioned away from the front end face of the tip 500.

[0058] Since the first end of the second deflection block 201 is rotatably connected to the inner wall surface of the protective part 102, and the drive assembly 300 is connected to the second end of the second deflection block 201, when the drive assembly 300 applies a driving force to the second end of the second deflection block 201, the second end of the second deflection block 201 can be brought closer to or further away from the appliance 400, thereby realizing the switching of the second deflection block 201 between the first state and the second state.

[0059] In some embodiments, in order to ensure that the second deflection block 201 is always within the protection space under any state, this embodiment sets the vertical distance between the end of the protection part 102 away from the second connection part 101 and the front end face 52 to be greater than the vertical distance between the second end of the second deflection block 201 and the front end face 52.

[0060] In some embodiments, in order to better control the switching of the second deflection block 201 between the first state and the second state, the drive assembly 300 shown in this embodiment includes a second traction member 301, which is a steel wire traction rope; the mounting base 100 is provided with a traction channel 121 extending axially along the tip 500.

[0061] The steel wire traction rope is inserted into the traction channel 121 and arranged along the extension direction of the traction channel 121; the first end of the steel wire traction rope extends into the protection space and is connected to the second end of the second deflection block 201.

[0062] Here, the second traction member 301 shown in this embodiment includes a screw drive mechanism, the output end of which is connected to the second end of the wire traction rope. Based on the traction force applied by the screw drive mechanism to the second end of the wire traction rope, the reciprocating movement of the wire traction rope within the traction channel 121 can be controlled.

[0063] Thus, as the wire traction rope moves toward the front of the tip 500 relative to the traction channel 121, the first end of the wire traction rope can drive the second end of the second deflection block 201 to deflect toward the center of the tip 500 until the second deflection block 201 comes into contact with the device 400 extending out of the clamp outlet 51.

[0064] Accordingly, as the wire traction rope moves toward the rear of the tip 500 relative to the traction channel 121, the first end of the wire traction rope can drive the second end of the second deflection block 201 to deflect toward the side away from the center of the tip 500 until the second deflection block 201 separates from the device 400 extending out of the clamp outlet 51.

[0065] like Figure 3 As shown, when a traction force is applied to the wire traction rope along the extension direction of the traction channel 121, the wire traction rope will move relative to the extension direction of the traction channel 121, thereby causing the second deflection block 201 to rotate relative to the protection part 102, so as to realize that the second deflection block 201 abuts or separates from the device 400 extending from the clamp outlet 51, thereby controlling the device 400 extending from the clamp outlet 51 to rise or fall.

[0066] In some embodiments, the clamping component shown in this embodiment includes an electro-deformable element connected to the inner wall surface of the protective portion 102; the drive assembly 300 includes a circuit board electrically connected to the electro-deformable element to control the energized state of the electro-deformable element. The circuit board is electrically connected to the electro-deformable element via a wire extending along the insertion tube of the endoscope.

[0067] In practical applications, based on the characteristic that the electro-deformable element deforms when energized and recovers its deformation when de-energized, when the electro-deformable element is de-energized by the circuit board, the electro-deformable element is in the first state, and the electro-deformable element is separated from the device 400 extending out of the clamp outlet 51.

[0068] Accordingly, when the electro-deformation element is energized by the circuit board, the electro-deformation element is in the second state and abuts against the device 400 extending from the clamp outlet 51.

[0069] Therefore, in this embodiment, by controlling the energization state of the electro-deformable element, the deflection of the device 400 extending from the clamp outlet 51 can be conveniently controlled.

[0070] In some embodiments, such as Figures 4 to 8 As shown, the mounting base 100 in this embodiment includes a first connecting portion 111 and a receiving portion 112; the first connecting portion 111 is detachably connected to the side wall of the tip 500; the receiving portion 112 is connected to the first connecting portion 111, one end of the receiving portion 112 is close to the front end of the tip 500, and the other end extends toward the rear end of the tip 500; the receiving portion 112 is provided with a receiving cavity that extends through the tip 500 along its axial direction.

[0071] The first connecting part 111 can be an annular member extending circumferentially along the tip 500, and the first connecting part 111 is fitted onto the side wall of the tip 500.

[0072] Furthermore, the clamping component includes a first deflection block 202; a drive assembly 300 is connected to a first end of the first deflection block 202 and drives the first end of the first deflection block 202 to move between a first position and a second position within the receiving cavity along the axial direction of the tip 500. When the first deflection block 202 is in the first position, the first deflection block 202 is hidden within the receiving cavity; when the first deflection block 202 is in the second position, the drive assembly 300 is also used to drive the first deflection block 202 to switch between the first state and the second state.

[0073] In this embodiment, a second groove is provided on one side of the first deflection block 202 facing the central axis of the tip 500. The second groove is used to fit with the side wall of the appliance 400.

[0074] like Figure 5 As shown, when the first end of the first deflection block 202 is in the first position, the first deflection block 202 is located inside the receiving cavity.

[0075] like Figure 6 As shown, when the first end of the first deflection block 202 is in the second position, one end of the first end of the first deflection block 202 is rotatably disposed in the receiving cavity, and the second end of the first deflection block 202 extends out of the receiving cavity and is located on the front side of the tip 500. The drive assembly 300 is also used to drive the first deflection block 202 to deflect relative to the mounting base 100 so that the first deflection block 202 switches between the first state and the second state.

[0076] In practical applications, when inserting the endoscope tip 500 into the human body, this embodiment can first connect the first connecting part 111 of the mounting base 100 to the side wall of the tip 500, and then place the first end of the first deflection block 202 in the first position of the receiving cavity, so that the lifting clamp component is not exposed during the insertion process, thereby avoiding scratches to the human body.

[0077] When the tip 500 reaches the lesion site and the instrument 400 extends from the forceps outlet 51, in this embodiment, the first end of the first deflection block 202 can be moved from the first position to the second position by the drive assembly 300. At this time, since the first end of the first deflection block 202 is rotatably disposed in the receiving cavity when the first end of the first deflection block 202 is in the second position, and the second end of the first deflection block 202 extends out of the receiving cavity, when the drive assembly 300 applies a driving force to the first deflection block 202, the first deflection block 202 will deflect relative to the mounting base 100.

[0078] Therefore, in this embodiment, based on the state switching of the first deflection block 202, the instrument 400 extending from the working forceps can be controlled to swing at a relatively large angle to assist the instrument 400 in sampling or treating the lesion.

[0079] In this embodiment, the arrangement design of the forceps components also facilitates cleaning of the forceps components after surgery.

[0080] In some embodiments, such as Figure 5 and Figure 6 As shown, the drive assembly 300 in this embodiment includes a first traction member 311 and a guide member 312. The first traction member 311 can also be a traction mechanism consisting of a lead screw drive mechanism and a steel wire traction rope as shown in the above embodiment. Here, the specific structure of the first traction member 311 will not be described in detail.

[0081] One end of the first traction member 311 is connected to the first end of the first deflection block 202, and the first end of the first deflection block 202 is provided with a connecting shaft 21; the guide member 312 is provided in the receiving cavity, the first end of the guide member 312 is provided in the first position, the second end of the guide member 312 is provided in the second position, the second end of the guide member 312 is provided with a limiting groove 32, and the guide member 312 guides the first deflection block 202 to move between the first position and the second position through the guide inclined surface 31.

[0082] like Figure 7 and Figure 8 As shown, the guide member 312 is provided with a guide slope 31, which extends from the first end of the guide member 312 to the second end of the guide member 312, such that the radial distance of the first end of the guide member 312 relative to the central axis of the tip 500 is greater than the radial distance of the second end of the guide member 312 relative to the central axis of the tip 500.

[0083] like Figure 7 As shown, when the first traction member 311 drives the first end of the first deflecting block 202 to the first position within the receiving portion 112 via the steel wire traction rope, the side of the first deflecting block 202 facing away from the central axis of the tip 500 is in contact with the guide slope 31, or the connecting shaft 21 on the first deflecting block 202 is in contact with the guide slope 31. At this time, the first deflecting block 202 has no interaction with the device 400 extending from the clamp outlet 51.

[0084] like Figure 8As shown, during the process of the first traction member 311 driving the first end of the first deflecting block 202 to move from the first position to the second position via the steel wire traction rope, under the guidance of the guide slope 31, the second end of the first deflecting block 202 gradually approaches the appliance 400 until the connecting shaft 21 on the first deflecting block 202 moves into the limiting groove 32. At this time, the second end of the first deflecting block 202 is located outside the receiving cavity. When the first traction member 311 applies a traction force to the first deflecting block 202, the first end of the first deflecting block 202 remains unchanged relative to the second position. Since the connecting shaft 21 on the first deflecting block 202 is rotatably disposed in the limiting groove 32, under the action of the traction force applied by the first traction member 311 to the first deflecting block 202, the first deflecting block 202 will deflect, thereby realizing the switching between the first state and the second state.

[0085] In this embodiment, when the first end of the first deflection block 202 is in the second position, in order to facilitate the deflection of the first deflection block 202 by driving the first deflection block 202 through the first traction member 311, the first traction member 311 is connected to the side of the first end of the first deflection block 202 that is away from the central axis of the tip 500. This allows the first traction member 311 to apply traction force to the first deflection block 202, causing the first deflection block 202 to rotate relative to the central axis of the connecting shaft 21. This enables the first deflection block 202 to abut or separate from the device 400 extending from the clamp outlet 51, thereby controlling the lifting or lowering of the device 400 extending from the clamp outlet 51.

[0086] Based on the scheme shown in the above embodiment, in order to better control the deflection of the instrument 400 extending from the clamp outlet 51, this embodiment also sets the radial distance of the lifting clamp component relative to the central axis of the tip 500 to be greater than the radial distance of the center of the clamp outlet 51 relative to the central axis of the tip 500.

[0087] Preferably, this embodiment also provides an endoscope, including: an endoscope instrument auxiliary device as described in any of the preceding claims.

[0088] Specifically, since the endoscope shown in this embodiment includes an endoscope instrument auxiliary device, and the specific structure of the endoscope instrument auxiliary device is as described in the above embodiments, the endoscope shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects brought about by all the technical solutions of the above embodiments, which will not be described in detail here.

[0089] In this embodiment, the endoscope is a direct-viewing endoscope. When the instrument is inserted along the working channel and initially extends out of the channel outlet, the extension direction of the instrument from the channel outlet is parallel to the central axis of the tip and the optical axis of the camera module on the tip.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
