Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an ultrasonic endoscope. Background Technology

[0002] In one existing ultrasound endoscopy device, an ultrasound probe is installed at the top of the endoscope. The endoscope and ultrasound are used to diagnose lesions in body cavities, so as to obtain clearer and more accurate tomographic images of tissues and organs, providing objective basis for doctors to treat the symptoms.

[0003] However, the endoscope and ultrasonic probe used in this device are quite difficult to repair and assemble.

[0004] Therefore, how to provide an easy-to-assemble ultrasonic endoscope is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an ultrasonic endoscope that is easy to assemble.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ultrasonic endoscope includes an ultrasonic module and an endoscope module. The ultrasonic module includes an ultrasonic support block, and the endoscope module includes an endoscope spindle assembly. The ultrasonic support block is provided with a mounting sleeve, and the endoscope spindle assembly is axially inserted into the mounting sleeve. The ultrasonic module includes a rotation locking assembly, and the angle between the endoscope spindle assembly and the mounting sleeve is adjustable. After the angle is locked by the rotation locking assembly, the endoscope spindle assembly can slide axially within the mounting sleeve.

[0008] For example, one of the endoscope spindle assembly and the rotation locking assembly is provided with a plurality of slots along the circumferential direction, and the other is provided with a locking block. The locking block can lock the relative angle between the mounting sleeve and the endoscope spindle assembly by engaging the corresponding slot in the radial direction, and the locking block can switch the slot it engages with to switch the angle of the endoscope spindle assembly relative to the mounting sleeve.

[0009] For example, when the rotation locking assembly locks the angle of the endoscope spindle assembly, the plurality of slots engage with the plurality of blocks one by one.

[0010] For example, the plurality of said slots are evenly arranged circumferentially.

[0011] For example, the rotation locking assembly includes two locking racks disposed in the mounting sleeve, the tooth surfaces of the two locking racks are arranged opposite each other, the endoscope spindle assembly is disposed between the two locking racks, and the teeth on the locking racks are the locking blocks.

[0012] For example, the relative angle between the endoscope spindle assembly and the mounting sleeve can be switched to any angle within a preset continuous angle range.

[0013] For example, the rotation locking assembly further includes a rotating ring sleeved on the outside of the endoscope spindle assembly, wherein a rotation limiting structure is provided between the rotating ring and the endoscope spindle assembly to rotate synchronously, and the rotating ring is adjustablely connected to the mounting sleeve.

[0014] For example, the endoscope mandrel assembly is axially slidably inserted into the rotating ring; the rotation limiting structure includes a groove on one of the rotating ring and the endoscope mandrel assembly, and a slider on the other, the groove being axially continuous, and the slider being slidably engaged with the groove.

[0015] For example, the mounting sleeve has a notch at one end radially away from the ultrasonic support block, and the notch extends axially through the support block; and / or, the mounting sleeve has a probe connection hole for axial insertion of an ultrasonic probe in the ultrasonic module into the probe connection hole.

[0016] For example, the rotating locking assembly includes a handle connected to the outer peripheral surface of the mounting sleeve and a locking body disposed between the handle and the endoscope spindle assembly; the handle can be swung to drive the locking body to circumferentially lock the endoscope spindle assembly to the mounting sleeve or unlock it.

[0017] The ultrasonic endoscope provided by this utility model only requires adding a mounting sleeve to the ultrasonic module to connect the endoscope module. The relative angle between the ultrasonic module and the endoscope module is adjustable, and through the rotation locking component, it can move axially relative to each other freely while the angle is locked. It is easy to assemble. During the examination or surgery, the relative position of the ultrasonic module and the endoscope module can be adjusted at will, ensuring the flexibility of use and making the operation more convenient. At the same time, the endoscope spindle assembly can serve as a guide structure to guide the axial movement of the ultrasonic module and improve the stability of the ultrasonic module's movement.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] The core of this invention is to provide an ultrasonic endoscope that is easy to assemble.

[0035] For a specific embodiment of the ultrasonic endoscope provided by this utility model, please refer to the following: Figures 1 to 4 It includes an endoscope module 2 and an ultrasound module 1, which are connected to form an ultrasound endoscope.

[0036] like Figure 2 As shown, the ultrasound module 1 includes an ultrasound support block 11 and an ultrasound probe 12 connected to the ultrasound support block 11. Specifically, one end of the ultrasound probe 12 is connected to one end of the ultrasound support block 11, for example, by insertion, bolting, or bonding. The ultrasound support block 11 can be used as a part held by the doctor. The ultrasound probe 12 can send ultrasound signals to the object being examined in the body cavity and receive ultrasound signals reflected from the object being examined.

[0037] like Figure 3 As shown, the endoscope module 2 includes an endoscope body 21 and an endoscope spindle assembly 22 connected to the endoscope body 21. The endoscope body 21 includes an endoscope control assembly. The endoscope spindle assembly 22 is connected to the endoscope body 21 at its first end in its extension direction, and to the endoscope image acquisition assembly at its second end in its extension direction. The endoscope spindle assembly 22 includes an endoscope spindle body and an endoscope sheath 221 sleeved on the outside of the endoscope spindle body. An operating handle is provided at the first end of the endoscope sheath 221, and a water inlet / outlet hole 224 is provided on the operating handle.

[0038] To connect the endoscope module 2 and the ultrasound module 1, such as Figure 1 and Figure 4As shown, a mounting sleeve 14 is provided on the outer side of the ultrasonic support block 11. Specifically, the ultrasonic support block 11 is located on one side of the mounting sleeve 14 in the radial direction, and can be fixedly connected or integrally formed. The endoscope spindle assembly 22 is axially inserted into the mounting sleeve 14. The ultrasonic module 1 is provided with a rotation locking assembly 13. The angle between the endoscope spindle assembly 22 and the mounting sleeve 14 is adjustable. Specifically, when the rotation locking assembly 13 is unlocked, the endoscope spindle assembly 22 and the mounting sleeve 14 can rotate relative to each other. After the endoscope spindle assembly 22 and the mounting sleeve 14 are angle-locked by the rotation locking assembly 13, the endoscope spindle assembly 22 can slide axially in the mounting sleeve 14. In addition, in the unlocked state, the endoscope spindle assembly 22 and the mounting sleeve 14 can also slide axially or remain axially fixed relative to each other.

[0039] It should be noted that, in the embodiments of this application, unless otherwise specified, the through direction of the mounting sleeve 14 is taken as the axial direction, and the circumferential and radial directions are defined with reference to the axis of the mounting sleeve 14.

[0040] In addition, to facilitate ultrasound and endoscopic examinations, the endoscope spindle assembly 22 is connected to the second end of the endoscope image acquisition assembly (see reference). Figure 1 The right end (middle) is the end closest to the patient or lesion; the first end (refer to...) Figure 1 The left end is the end closest to the operator, such as the doctor; the ultrasound probe 12 includes a detection part, which is located on the same side of the ultrasound support block 11 as the second end of the endoscope core assembly 22. Figure 1 In this orientation, the second end of the endoscope mandrel assembly 22 and the detection portion of the ultrasound probe 12 are located on the right side of the ultrasound support block 11, and are used for patient detection. Specifically, the endoscope mandrel assembly 22 and the ultrasound probe 12 extend in parallel and can extend axially.

[0041] During operation, the relative angle between the endoscope spindle assembly 22 and the mounting sleeve 14 can be adjusted as needed. Specifically, the angle of the ultrasound module 1 can be adjusted around the endoscope spindle assembly 22. After adjustment, the endoscope spindle assembly 22 is circumferentially locked to the mounting sleeve 14 by rotating the locking assembly 13. At this time, the ultrasound module 1 can still move freely along the axial direction of the endoscope spindle assembly 22, so that the relative axial position of the endoscope spindle assembly 22 and the ultrasound probe 12 can be adjusted arbitrarily to meet the needs of information acquisition or surgery. For example, during the operation of the endoscope module 2, the ultrasound module 1 can still slide along the axial direction after being circumferentially locked, without interfering with the surgical execution of the endoscope module 2 during the operation.

[0042] It can be seen that in this type of ultrasound endoscope, only the installation sleeve 14 needs to be added to the ultrasound module 1 to connect the endoscope module 2. The relative angle between the ultrasound module 1 and the endoscope module 2 is adjustable, and through the rotation locking assembly 13, they can move axially relative to each other at will while the angle is locked. Assembly is convenient. During the examination or surgery, the axial relative position of the ultrasound module 1 and the relative position of the endoscope module 2 near the patient can be adjusted at will, ensuring the flexibility of use and making the operation more convenient. At the same time, the endoscope spindle assembly 22 can serve as a guide structure to guide the axial movement of the ultrasound module 1 and improve the stability of the movement of the ultrasound module 1.

[0043] For the circumferential rotation angle adjustment between the mounting sleeve 14 and the endoscope spindle assembly 22, a stepped adjustment method can be adopted. Stepped adjustment means that there are fixed levels during the adjustment process, and the relative angle adjustment can only switch between preset levels. Using a stepped adjustment method can improve the controllability of angle adjustment, so that the locking angle position between the mounting sleeve 14 and the endoscope spindle assembly 22 can be known each time.

[0044] Specifically, one of the endoscope spindle assembly 22 and the rotation locking assembly 13 has multiple slots 222 arranged circumferentially on its upper side, and the other has a locking block 132. The locking block 132 can be radially engaged with the corresponding slot 222 to lock the relative angle between the mounting sleeve 14 and the endoscope spindle assembly 22. Furthermore, the locking block 132 can switch the slots 222 it engages with to change the angle of the endoscope spindle assembly 22 relative to the mounting sleeve 14. Each slot 222 corresponds to a specific position; by engaging the same locking block 132 with different slots 222, different positions can be switched. This engagement of the slots 222 and the locking block 132 achieves rotational limiting, ensuring the reliability of circumferential limiting.

[0045] For example, such as Figures 1 to 4 As shown, multiple slots 222 are fixedly arranged in sequence along the circumferential direction on the outer peripheral surface of the endoscope spindle assembly 22, and the rotation locking assembly 13 includes a locking block 132 arranged facing the outer peripheral surface of the endoscope spindle assembly 22.

[0046] Specifically, the slot 222 can be directly formed on the outer peripheral surface of the endoscope spindle assembly 22, specifically on the outer peripheral surface of the outer sheath 221. In this case, the endoscope outer sheath 221 has a threaded design, which engages with the locking block 132 of the rotary locking assembly 13 to achieve rotational locking. Alternatively, to reduce damage to the outer peripheral surface of the endoscope spindle assembly 22 (usually referring to the outer peripheral surface of the outer sheath 221), the rotary locking assembly 13 also includes a rotating ring 135 sleeved on the outside of the endoscope spindle assembly 22. The rotating ring 135 is angularly adjustable and connected to the mounting sleeve 14. In this case, the slot 222 is formed on the outer peripheral surface of the rotating ring 135.

[0047] Of course, in other embodiments, the locking block 132 may be disposed on the endoscope spindle assembly 22, and the slot 222 may be disposed in the rotation locking assembly 13.

[0048] It should be noted that during axial movement, the locking block 132 and its engaging slot 222 move relative to each other axially, which can serve as a guide. Specifically, the slot 222 extends from the first end to the second end of the endoscope spindle assembly 22, and the locking block 132 extends from one axial end to the other axial end of the mounting sleeve 14 to ensure the reliability of axial guidance.

[0049] Furthermore, to improve the reliability of circumferential limiting, when the rotation locking assembly 13 locks the angle of the endoscope spindle assembly 22, multiple slots 222 engage with multiple locking blocks 132 in a one-to-one correspondence. Optionally, such as Figure 4 As shown, there are multiple card slots 222 and card blocks 132, and the number can be the same or different. Each time a gear is switched, a card block 132 is engaged in each of the card slots 222, or all the card blocks 132 are engaged in one card slot 222. Of course, in this embodiment, only one card block 132 may be provided.

[0050] Furthermore, to improve the uniformity of angle adjustment, multiple slots 222 are evenly arranged circumferentially. Therefore, when the same locking block 132 switches between adjacent slots 222, the endoscope spindle assembly 22 rotates at the same angle relative to the mounting sleeve 14. For example, as... Figure 3 As shown, multiple slots 222 are distributed circumferentially on the outer circumferential surface of the endoscope spindle assembly 22. At this time, the endoscope spindle assembly 22 can be locked by the rotation locking component 13 each time it rotates in the same direction by the same set angle A, and can rotate 360° / A times, providing 360° / A positions. For example, if A is 18°, 20 positions are provided, or if A is 10°, 36 positions are provided.

[0051] Furthermore, such as Figure 4 As shown, the rotary locking assembly 13 includes a locking body, which includes two locking racks 134 disposed in the mounting sleeve 14. The tooth surfaces of the two locking racks 134 are arranged opposite each other, and the endoscope spindle assembly 22 is disposed between the two locking racks 134. The teeth on the locking racks 134 serve as locking blocks 132. By providing two locking racks 134 in the rotary locking assembly 13 to provide locking blocks 132, the assembly of the endoscope spindle assembly 22 on the ultrasonic support block 11 is facilitated. During assembly, the two locking racks 134 can be engaged with the outside of the endoscope spindle assembly 22 and then uniformly assembled in the mounting sleeve 14; or, the two locking racks 134 can be fixed to the mounting sleeve 14 first, and then the endoscope spindle assembly 22 can be axially inserted between the two locking racks 134.

[0052] For example, such as Figure 4 As shown, the endoscope spindle assembly 22 has a cylindrical structure, and the slot 222 is provided on the outer peripheral surface of the endoscope spindle assembly 22. The tooth surface of the locking rack 134 can be an arc-shaped surface, and the locking blocks 132 on the locking rack 134 are arranged along the arc to match the outer peripheral surface of the endoscope spindle assembly 22.

[0053] For example, such as Figure 4 As shown, the mounting sleeve 14 has a notch 141 at the end that is radially away from the ultrasonic support block 11, and the notch 141 extends through the shaft axially. At this time, the mounting sleeve 14 is a U-shaped frame, and the two locking racks 134 and the endoscope spindle assembly 22 can be assembled from either the radial opening or the axial end opening of the mounting sleeve 14.

[0054] To achieve angle locking and unlocking between the locking block 132 and the slot 222, the locking block 132 can be exemplarily configured as an elastic element. During angle adjustment, the endoscope spindle assembly 22 rotates, and the locking block 132 rotates synchronously with the endoscope spindle assembly 22. Under the pressure of the slot wall of the slot 222, it is compressed or oscillates and deforms. When the endoscope spindle assembly 22 rotates to its position, the locking block 132 returns to its original position and springs back into the corresponding slot 222, automatically locking itself. In this case, the rotating locking assembly 13 only needs to have a structure with the locking block 132, and no other locking structure needs to be added separately. Based on this, the locking block 132 can be fixedly connected to the mounting sleeve 14. For example, the locking rack 134 including the locking block 132 can be fixed in the mounting sleeve 14, specifically by welding or bolting; or, in other embodiments, the locking block 132 can be directly and integrally set on the mounting sleeve 14.

[0055] Alternatively, the rotary locking assembly 13 may also include a handle 131, which is connected to the locking body. For ease of operation, the handle 131 may be connected to the outer peripheral surface of the mounting sleeve 14. By swinging the handle 131, the locking body can be circumferentially locked to the endoscope spindle assembly 22 in the mounting sleeve 14 or unlocked. Optionally, the handle 131 can be unlocked when it is parallel to the axial direction and locked when it is perpendicular to the axial direction.

[0056] Based on this, the locking body also includes a first transmission mechanism. The handle 131 is connected to the locking rack 134 through the first transmission mechanism. The first transmission mechanism locks or unlocks the endoscope spindle assembly 22 by moving the two locking racks 134 closer or further apart. Optionally, the first transmission mechanism connects to and moves only one locking rack 134 closer or further away from the other locking rack 134, or the first transmission mechanism is connected to both locking racks 134 simultaneously, moving the two locking racks 134 closer or further apart. In addition, the first transmission mechanism specifically includes a lead screw and nut transmission mechanism, a gear and rack transmission mechanism, a screw transmission mechanism, or a crank and slider transmission mechanism to adjust the spacing of the locking racks 134 by rotating the handle 131.

[0057] Additionally, when the two locking racks 134 are far apart, to prevent the endoscope spindle assembly 22 from radially shifting due to the lack of locking racks 134, such as... Figure 5 As shown, in a specific embodiment, the ultrasound module 1 further includes a positioning block 111, which is fixed to the ultrasound support block 11. Specifically, a positioning block 111 can be respectively provided on the ultrasound support block 11 on both sides of the mounting sleeve 14. The positioning block 111 has an arc-shaped positioning surface. When the two locking racks 134 are far apart, the endoscope spindle assembly 22 can be supported by the arc-shaped positioning surface. When the two locking racks 134 are close together for locking, there is no need to radially adjust the endoscope spindle assembly 22. The endoscope spindle assembly 22 can be directly clamped and locked.

[0058] In addition, the angle adjustment between the mounting sleeve 14 and the endoscope spindle assembly 22 can also be achieved using a stepless adjustment method. Stepless adjustment refers to the ability to continuously and smoothly switch the locked angle between the mounting sleeve 14 and the endoscope spindle assembly 22 within a certain range. Using a stepless adjustment method can expand the range of angle adjustment.

[0059] Specifically, such as Figures 6 to 11 As shown, the relative angle between the endoscope spindle assembly 22 and the mounting sleeve 14 can be switched to any angle within a preset continuous angle range. Optionally, the preset continuous angle is 360°, or it can be 180°.

[0060] Furthermore, such as Figure 10 As shown, the rotation locking assembly 13 also includes a rotating ring 135 sleeved on the outside of the endoscope spindle assembly 22. A rotation limiting structure is provided between the rotating ring 135 and the endoscope spindle assembly 22 to allow for synchronous rotation. The rotating ring 135 is angularly adjustable to the mounting sleeve 14. In this case, the rotation locking and unlocking is achieved through the rotating ring 135, which can reduce damage to the endoscope spindle assembly 22, and the rotating ring 135 will not interfere with the axial relative movement between the mounting sleeve 14 and the endoscope spindle assembly 22.

[0061] Based on this, the endoscope spindle assembly 22 can also be configured to be axially slidably inserted into the rotating ring 135. The rotation limiting structure includes a groove 223 on one of the rotating ring 135 and the endoscope spindle assembly 22, and a slider 136 on the other. In one embodiment, the rotation limiting structure includes a groove 223 on the inner circumferential surface of the rotating ring 135 and a slider 136 on the outer circumferential surface of the endoscope spindle assembly 22. The groove 223 extends axially, and the slider 136 slides in conjunction with the groove 223. At this time, the groove 223 and the slider 136 limit rotation while also providing axial guidance, and are axially locked to the mounting sleeve 14 when the rotating ring 135 is circumferentially rotated and locked to the mounting sleeve 14.

[0062] For example, two grooves 223 are disposed opposite to each other on the outer peripheral surface of the endoscope spindle assembly 22, specifically disposed on the outer sheath 221. Two sliders 136 are disposed opposite to each other on the inner peripheral surface of the rotating ring 135, and the sliders 136 are fitted into the grooves 223 in a one-to-one correspondence. In addition, the grooves 223 can be arc-shaped grooves or square grooves, and the shape of the sliders 136 is adapted to fit them.

[0063] Additionally, a rotating groove can be provided on the mounting sleeve 14 to axially limit the rotating ring 135 and prevent it from moving axially on the mounting sleeve 14. Of course, in other embodiments, the rotating ring 135 can also be fixedly connected to the endoscope spindle assembly 22, and the rotating ring 135 can be axially slidably connected to the mounting sleeve 14.

[0064] Furthermore, such as Figure 10 As shown, the rotary locking assembly 13 also includes a handle 131, which is connected to the locking body. For ease of operation, the handle 131 can be connected to the outer peripheral surface of the mounting sleeve 14. By swinging the handle 131, the locking body can be circumferentially locked to the endoscope spindle assembly 22 in the mounting sleeve 14 or unlocked. Optionally, the handle 131 can be unlocked when it is parallel to the axial direction and locked when it is perpendicular to the axial direction.

[0065] Based on this, the locking body also includes a second transmission mechanism connected between the rotating ring 135 and the handle 131. The second transmission mechanism can lock or unlock the rotating ring 135 by moving closer to or further away from it.

[0066] Exemplarily, the rotary locking assembly 13 uses friction to achieve rotary locking or unlocking of the endoscope spindle assembly 22. Specifically, the outer circumferential surface of the rotating ring 135 has a friction surface. After the rotating ring 135 rotates to its position, it approaches and is supported by the friction surface through the second transmission mechanism to achieve friction locking. Specifically, the second transmission mechanism is built into the mounting sleeve 14 and / or the ultrasonic support block 11. Specifically, the second transmission mechanism includes a friction rod 133, which moves radially to contact and lock the rotating ring 135, or to separate from the rotating ring 135. The second transmission mechanism also includes a screw and nut transmission mechanism, a gear and rack transmission mechanism, a screw transmission mechanism, a crank and slider transmission mechanism, etc., connected between the friction rod 133 and the handle 131, so as to drive the friction rod 133 to move linearly through the rotation of the handle 131.

[0067] In addition, the assembly of the ultrasonic support block 11 and the ultrasonic probe 12, such as Figure 1 As shown, the ultrasonic support block 11 is provided with a probe connection hole 15 for axial insertion of the ultrasonic probe 12 in the ultrasonic module into the probe connection hole 15. The structure is simple and easy to assemble. For example, as... Figure 2 As shown, the probe connection hole 15 can be an axially through-hole structure, or in other embodiments, a blind hole. One end of the ultrasonic probe 12 is inserted into the probe connection hole 15. In addition to insertion, the probe connection hole 15 and the ultrasonic probe 12 can also be further bonded and fixed.

[0068] It should be noted that when an element is referred to as "fixing" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as "connecting" another element, it can be directly connected to the other element or there may be an intervening element.
