Description

Technical Field

[0001] This application relates to the field of medical testing technology, and in particular to an endoscope operating unit, an endoscope, and a medical device. Background Technology

[0002] With the development of the medical industry, endoscopic technology has become increasingly sophisticated. In current minimally invasive endoscopic surgeries, in order to achieve precise and flexible operation within complex and narrow human body areas, laparoscopy typically employs a combination of a lens, a skeletal frame, and a traction rope. A lever is used to control the pulling of the traction rope, thereby adjusting the angle and position of the skeletal frame, which in turn controls the angle and position of the lens. This allows the lens to move smoothly within the narrow cavity to monitor images within the abdominal cavity.

[0003] With existing endoscopic probes, medical staff need to constantly adjust the probe angle by moving it in a predetermined direction to insert the endoscope. Post-operatively, when removing the endoscope from the abdominal incision, medical staff often need to repeatedly adjust the lever to reposition the probe. In endoscopic surgery, medical staff often use a combination of multiple medical instruments to complete the procedure, and the constant adjustment of levers to reposition the endoscope undoubtedly consumes a significant amount of their energy. Utility Model Content

[0004] In view of this, it is necessary to provide an endoscope, endoscope operating unit, and medical device that are easy to reposition to reduce the difficulty of surgery, in order to solve the above problems.

[0005] Embodiments of this application provide an endoscope operating unit, including:

[0006] The shell has an internal cavity;

[0007] A transmission assembly is disposed in the inner cavity and connected to the bending part of the endoscope to drive the endoscope to bend. The transmission assembly has a rotating part that rotates about a rotation axis.

[0008] A toggle element, with one end located outside the housing and the other end connected to the transmission assembly, drives the transmission assembly to move;

[0009] The reset assembly includes a first elastic element and a second elastic element fixedly connected to the housing and respectively connected to the two ends of the rotating part in the radial direction, providing an elastic force to drive the rotating part to rotate to the initial state.

[0010] In at least one embodiment of this application, the rotating part includes a gear;

[0011] The gear is provided with a first meshing section, a second meshing section, a first opening and a second opening in the circumferential direction. The first opening and the second opening are arranged opposite each other in the radial direction of the gear. The first elastic member extends into the first opening and is fixedly connected to the gear, and the second elastic member extends into the second opening and is fixedly connected to the gear.

[0012] In at least one embodiment of this application, the transmission assembly further includes a transmission section, the two ends of which are respectively connected to a toggle member and the rotation axis of the rotating section, providing a force to drive the rotating section to rotate about its rotation axis.

[0013] In at least one embodiment of this application, the gear further includes a protruding first fixing portion and a second fixing portion;

[0014] One end of the first elastic element extends into the first opening and is sleeved on the first fixing part;

[0015] One end of the second elastic member extends into the second opening and is fitted onto the second fixing part.

[0016] In at least one embodiment of this application, the endoscope operating part further includes a connecting component whose middle part is fixed to the rotation axis of the rotating part, and whose two ends fix the first elastic element to the first fixing part and the second elastic element to the second fixing part.

[0017] In at least one embodiment of this application, the connecting component includes a first connector and a fastener;

[0018] The first connector includes a first connecting part, a fastening part, and a second connecting part arranged sequentially. The first connecting part is sleeved on the first fixing part, and the second connecting part is sleeved on the second fixing part.

[0019] The fastening part has a first fastening hole, and the rotation axis of the rotating part has a second fastening hole directly opposite the first fastening hole. The fastener passes through the first fastening hole and is fixed in the second fastening hole.

[0020] In at least one embodiment of this application, the endoscope operating unit further includes two second connectors;

[0021] The first elastic element and the second elastic element are respectively fixedly connected to the housing through two second connecting members.

[0022] In at least one embodiment of this application, the first elastic member and the second elastic member are springs, which are connected to both ends of the rotating part along the length direction of the endoscope operating part.

[0023] An endoscope includes an endoscope operating section as described above.

[0024] A medical device comprising the endoscope described above.

[0025] The endoscope, endoscope operating unit, and medical device described above connect the first and second elastic elements to the radial ends of the rotating unit, respectively. Thus, when medical personnel adjust the endoscope angle by moving the actuating element, the first and second elastic elements deform with the transmission assembly. After the endoscope is used and the medical personnel remove their fingers from the actuating element, the transmission assembly automatically resets under the elastic force of the first and second elastic elements, avoiding the cumbersome postoperative operation of manually moving the actuating element to reset the endoscope.

Detailed Implementation

[0035] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Example 1

[0039] Please see Figure 1 , Figure 2 and Figure 3Embodiment 1 of this application provides an endoscope operating unit 100, including a housing 10, a transmission assembly 20, an actuating member 30, and a reset assembly 50. Specifically, the housing 10 has an inner cavity 10a, and the transmission assembly 20 is disposed in the inner cavity 10a and connected to the bending portion of the endoscope for driving the endoscope to bend. One end of the actuating member 30 is disposed outside the housing 10, and the other end is connected to the transmission assembly 20, so that medical personnel can drive the transmission assembly 20 to move by actuating the actuating member 30, and the transmission assembly 20 drives the endoscope to bend. The reset assembly 50 includes a first elastic member 51 and a second elastic member 52 fixedly connected to the housing 10. Further, the transmission assembly 20 has a rotating portion 212 that rotates about a rotation axis, and the first elastic member 51 and the second elastic member 52 are respectively connected to the two ends of the rotating portion 212 in the radial direction to provide an elastic force to drive the rotating portion 212 to rotate to the initial state after the endoscope is used.

[0040] In one specific embodiment, the actuating element 30 is a lever.

[0041] It should be noted that the endoscopic manipulation unit 100 is a tool used in minimally invasive surgery, typically for observing and manipulating organs within the abdominal cavity. During endoscopic manipulation unit 100 surgery, the patient, after preoperative preparation, lies supine on the operating table. Medical personnel puncture the abdominal wall at the umbilicus or other designated site using a pneumoperitoneum needle, introducing carbon dioxide into the abdominal cavity to inflate it. Then, a trocar is inserted into the abdominal cavity, and a small incision of 0.5cm-1cm is made at the umbilicus or other site to insert other manipulators. The endoscopic manipulation unit 100 is inserted into the trocar to guide it into the patient's abdominal cavity, and is connected to a cold light source to emit light at its head, facilitating the observation and examination of the patient's abdominal tissues or organs in conjunction with other manipulators.

[0042] Furthermore, during the insertion of the endoscope operating unit 100 into the abdominal cavity, medical personnel need to continuously adjust the length and angle of the endoscope probe by moving the adjusting element 30 to avoid the patient's internal organs. Because the length and angle of the endoscope probe are adjusted during insertion, medical personnel need to adjust the endoscope probe back to its original position when the endoscope operating unit 100 is withdrawn from the abdominal cavity. In existing technologies, when the endoscope is withdrawn, medical personnel need to perform the same operation and continuously move the adjusting element 30 to return the angle of the curved part of the endoscope to its original position. Since medical personnel need to insert multiple medical instruments into the abdominal cavity and operate on multiple instruments simultaneously to complete the examination during endoscope operation unit 100 surgery, the need to continuously adjust the angle of the endoscope to remove it from the abdominal cavity distracts medical personnel and increases the difficulty of abdominal surgery. Based on this, the endoscope operating unit 100 provided in Embodiment 1 of this application connects the first elastic element 51 and the second elastic element 52 to the two ends of the rotating part 212 radially, respectively. Thus, during endoscopic surgery, after the medical staff adjusts the angle of the endoscope by moving the actuating element 30, the first elastic element 51 and the second elastic element 52 deform with the rotating part 212. After the endoscopic surgery is completed and the medical staff removes their fingers from the actuating element 30, the force on the actuating element 30 is released, resulting in the release of the force exerted by the actuating element 30 on the first elastic element 51 and the second elastic element 52. At this time, the first elastic element 51 and the second elastic element 52 return to their original shape under their own elastic force, driving the transmission assembly 20 to move. The transmission assembly 20 then causes the curved portion of the endoscope to automatically return to its original position, thereby avoiding the cumbersome operation of manually moving the actuating element 30 to reset the endoscope after endoscopic surgery. Furthermore, the transmission assembly 20, extending from one end of the inner cavity 10a, is connected to the traction rope 40 and the multi-section snake bone, and then to the endoscope probe. Thus, when medical personnel move the actuating element 30, the actuating element 30 drives the transmission assembly 20 to move, which in turn drives the traction rope 40, the multi-section snake bone, and the endoscope probe to move, thereby changing the extension length and angle of the endoscope probe. The adjustment of the endoscope probe's length and angle is part of existing technology and will not be described further here.

[0043] It is understood that the number and location of the elastic elements are not limited to this. For details, please refer to [link / reference needed] in this embodiment. Figure 2 and Figure 3The first elastic element 51 and the second elastic element 52 are respectively connected to both ends of the rotating part 212 in the radial direction. Thus, when the rotating part 212 rotates around its rotation axis to change the angle of the curved portion of the endoscope (either adjusting the angle of the curved portion or resetting the curved portion), the first elastic element 51 and the second elastic element 52 provide a balanced restoring force to the rotating part 212, thereby avoiding the problem of increased friction caused by the eccentricity of the rotating part 212 with its rotation axis. In another embodiment, the number of elastic elements can be three, four, or five, etc., with one end fixedly connected to the housing 10 and the other end equally spaced in a matrix configuration to the rotating part 212. This allows the rotating part 212 to be subjected to force from all directions when it rotates, thereby preventing the eccentricity of the rotating part 212.

[0044] In one specific embodiment, the first elastic element 51 and the second elastic element 52 are elongated springs, which are connected to both ends of the rotating part 212 along the length of the endoscope operating part 100. It should be noted that in actual use, the endoscope operating part 100 is held in the hand of a medical professional and has an elongated structure. Therefore, when the first elastic element 51 and the second elastic element 52 are connected to the rotating part 212 along the length of the endoscope operating part 100, they are located within the inner cavity 10a and can adapt to the shape of the endoscope operating part 100, thereby fully utilizing the space of the endoscope operating part 100, avoiding the need for extra space to accommodate the first elastic element 51 and the second elastic element 52, and reducing the overall volume of the endoscope operating part 100.

[0045] Furthermore, the rotating part 212 includes a gear 21. Specifically, the gear 21 is circumferentially provided with a first meshing section 213, a second meshing section 214, a first opening 21a, and a second opening 21b. The first opening 21a and the second opening 21b are arranged radially opposite to each other along the gear 21. A first elastic member 51 extends into the first opening 21a and is fixedly connected to the gear 21. A second elastic member 52 extends into the second opening 21b and is fixedly connected to the gear 21. This solution, by providing the first opening 21a and the second opening 21b radially opposite to each other on the gear 21 for the first elastic member 51 and the second elastic member 52 to extend into, avoids the first elastic member 51 and the second elastic member 52 being fixed to the gear 21 by stacking when connected, thereby reducing the thickness of the endoscope operating part 100.

[0046] Furthermore, the rotating part 212 also includes a rack 22. In one specific embodiment, there are two racks 22 and two traction ropes 40. The two racks 22 are respectively engaged with the first engagement section 213 and the second engagement section 214. Preferably, the first engagement section 213 and the second engagement section 214 are also arranged opposite to each other. The two traction ropes 40 are respectively located at the end of one of the racks 22 that extends out of the inner cavity 10a, and the end of each traction rope 40 away from the rack 22 is connected to the snake bone and the probe. In this application, by actuating the actuating element 30, the gear 21 is driven to rotate. The gear 21 drives the two racks 22 to move in opposite directions, so as to simultaneously drive the two traction ropes 40 to move in different directions, thereby changing the angle of the snake bone and the probe.

[0047] Please combine Figure 6 and Figure 7 The above-described solution involves fixing the first elastic element 51 to the gear 21 via the first opening 21a and the second elastic element 52 to the gear 21 via the second opening 21b. When the endoscope operating section 100 adjusts the angle to drive the gear 21 to rotate, since the other ends of the first elastic element 51 and the second elastic element 52 are both fixed to the housing 10, the first elastic element 51 and the second elastic element 52 bend and deform until the gear 21 contacts the first elastic element 51 and the second elastic element 52 on the sidewalls of the first opening 21a and the second opening 21b. At this point, the first elastic element 51 and the second elastic element 52 will stop the gear 21, thereby preventing the gear 21 from rotating excessively and causing the probe angle to be adjusted too much, which could damage the internal tissues of the human body. Furthermore, fixing the first elastic element 51 to the gear 21 via the first opening 21a and the second elastic element 52 to the gear 21 via the second opening 21b provides a more secure fixation compared to fixing the first elastic element 51 and the second elastic element 52 to the peripheral wall of the gear 21.

[0048] Please see Figure 3 The transmission assembly 20 also has a transmission section 211. Specifically, the two ends of the transmission section 211 are respectively connected to the rotation axis of the actuating member 30 and the rotating part 212, providing a force to drive the rotating part 212 to rotate around its rotation axis.

[0049] In one specific embodiment, the transmission part 211 is a transmission shaft integrally formed with the rotating part 212. One end of the transmission part 211 is fixedly connected to the rotation axis of the rotating part 212, and the other end extends out of the housing 10 and is connected to the actuating member 30. The actuating member 30 can rotate about the transmission part 211 as the axis. Thus, when the endoscope operation part 100 adjusts the probe angle, the medical staff presses and rotates the actuating member 30. The rotating part 212 transmits the rotational force to the transmission part 211, which drives the gear 21 to rotate. The gear 21 drives the rack 22 to move, thereby converting the circumferential rotation of the gear 21 into the linear motion of the two racks 22. When the two racks 22 move in a straight line, each rack 22 drives a traction rope 40 to move linearly, thereby moving the snake bone and the endoscope probe through the two traction ropes 40, thus changing the angle of the endoscope probe.

[0050] It is understood that the type of transmission part 211 is not limited to this, and other structures that can connect the actuating member 30 and the gear 21 are all within the scope of protection of this application.

[0051] Please see Figure 4 The gear 21 includes a base 2121, and the rotation axis of the gear 21 is located on the base 2121. A first meshing section 213 and a second meshing section 214 are disposed on the circumferential surface of the base 2121. The base, the first meshing section 213, and the second meshing section 214 enclose and form the aforementioned first opening 21a and second opening 21b.

[0052] In one specific embodiment, the base 2121 is the gear disk of the gear 21, and the first meshing section 213 and the second meshing section 214 are toothed portions. Preferably, in the original state of the endoscope operating section 100 (i.e., in... Figure 2 When the two traction ropes 40 shown are neither extended nor retracted, the first engagement section 213 and the second engagement section 214 are arranged radially opposite each other. At this time, the first opening 21a and the second opening 21b are also arranged radially opposite each other and connect to the inner cavity 10a.

[0053] Please continue to combine Figure 3 and Figure 4 To further improve the tightness of the connection between gear 21 and the first elastic member 51 and the second elastic member 52, in a specific embodiment, gear 21 further includes a protruding first fixing part 215 and a second fixing part 216. Specifically, the first fixing part 215 is disposed on the base 2121 and located at the first opening 21a, and one end of the first elastic member 51 extends into the first opening 21a and is sleeved on the first fixing part 215. The second fixing part 216 is disposed on the base 2121 and located at the second opening 21b, and one end of the second elastic member 52 extends into the second opening 21b and is sleeved on the second fixing part 216.

[0054] In one specific embodiment, the first fixing part 215 and the second fixing part 216 are protruding column structures integrally formed with the base 2121. The ring at the end of the first elastic member 51 is sleeved on the first fixing part 215, and the ring at the end of the second elastic member 52 is sleeved on the second fixing part 216, so as to fix the first elastic member 51, the second elastic member 52 and the base 2121.

[0055] It should be noted that the types of the first fixing part 215 and the second fixing part 216, as well as their arrangement and shape with the base 2121, are not limited thereto. Any other structure that can be connected to the base 2121 and fixedly connected to the first elastic member 51 and the second elastic member 52 is within the scope of protection.

[0056] To ensure the secure fixation of the first elastic element 51, the second elastic element 52, and the gear 21, in one specific embodiment, the endoscope operating part 100 further includes a connecting assembly 60 whose central portion is fixed to the rotation axis of the rotating part 212. The connecting assembly 60 fixes the first elastic element 51 to the first fixing part 215 and the second elastic element 52 to the second fixing part 216 at both ends. This solution, by using the connecting assembly 60 to fix the first elastic element 51 to the first fixing part 215 and the second elastic element 52 to the second fixing part 216, further increases the stability of the fixation between the first elastic element 51, the second elastic element 52, and the base 2121 of the gear 21.

[0057] Specifically, please see Figure 3 , Figure 4 and Figure 5 The connecting assembly 60 includes a first connector 61 and a fastener 62. The first connector 61 includes a first connecting portion 611, a fastening portion 612, and a second connecting portion 613 arranged sequentially. The first connecting portion 611 is sleeved on the first fixing portion 215, and the second connecting portion 613 is sleeved on the second fixing portion 216. The fastening portion 612 has a first fastening hole 612a, and the rotating portion 212 has a second fastening hole 212a opposite to the first fastening hole 612a. The fastener 62 passes through the first fastening hole 612a and is fixed in the second fastening hole 212a.

[0058] It should be noted that, in one specific embodiment, the first connecting portion 611, the fastening portion 612, and the second connecting portion 613 are integrally formed sheet structures. In the above solution, after the first elastic member 51 is fitted onto the first fixing portion 215 and the second elastic member 52 is fitted onto the second fixing portion 216, the first connecting portion 611 is fitted onto the first fixing portion 215 and the second connecting portion 613 is fitted onto the second fixing portion 216, thereby pressing and fixing the first elastic member 51 and the second elastic member 52 onto the first fixing portion 215 and the second fixing portion 216, increasing the firmness of the fixation. Further, in the above solution, after the first elastic member 51 is pressed onto the first fixing portion 215 by the first connecting portion 611 and the second elastic member 52 is pressed onto the second fixing portion 216 by the second connecting portion 613, the fastening portion 612 is fixed to the base portion 2121 by the fastener 62, thereby fixing the first elastic member 51 and the second elastic member 52 onto the base portion 2121. Furthermore, the pressure of the fastener 62 on the fastening portion 612 is transmitted to the first connecting portion 611 and the second connecting portion 613 to compress the first elastic element 51 and the second elastic element 52, thereby further increasing the tightness between the first elastic element 51, the second elastic element 52 and the gear 21 base 2121. In a specific embodiment, the fastener 62 is a locking screw.

[0059] Specifically, please refer to Figure 5 The first connecting part 611 has a first connecting hole 611a, which is fitted onto the first fixing part 215. The second connecting part 613 has a second connecting hole 613a, which is fitted onto the second fixing part 216.

[0060] The above solution involves creating a first connecting hole 611a in the first connecting portion 611 and a second connecting hole 613a in the second connecting portion 613 to fit the first connecting member 61 onto the first fixing portion 215 and the second fixing portion 216. Since the first connecting member 61 is a single, integrated piece, during the production and assembly of the endoscope operating part 100, the ring at the end of the first elastic member 51 is first fitted onto the first fixing portion 215, and the ring at the end of the second elastic member 52 is fitted onto the second fixing portion 216. Then, by holding the first connecting member 61 and aligning the first connecting hole 611a with the first fixing portion 215 and the second connecting hole 613a with the second fixing portion 216, the first connecting member 61 can be directly fitted onto the first fixing portion 215 and the second fixing portion 216. Finally, by inserting the fastener 62 through the first fastening hole 612a and tightening it into the second fastening hole 212a, the gear 21 can be installed, making the operation simple.

[0061] Furthermore, to facilitate both contact and fixation of the first connector 61 to the base 2121, and to facilitate its fitting onto the first fixing part 215 and the second fixing part 216, in a specific embodiment, the first connector 61 further includes a third connector 614 and a fourth connector 615. Specifically, the two ends of the third connector 614 are respectively fixed to the fastening part 612 and the first connector 611, and one end of the third connector 614 extends from the fastening part 612 away from the base 2121. The two ends of the fourth connector 615 are respectively fixed to the fastening part 612 and the second connector 613, and one end of the fourth connector 615 extends from the fastening part 612 away from the base 2121.

[0062] In one specific embodiment, the first connecting portion 611, the second connecting portion 613, the fastening portion 612, the third connecting portion 614, and the fourth connecting portion 615 are integrally formed. Preferably, the furthest distance between the third connecting portion 614 and the fastening portion 612 is equal to the height of the first fixing portion 215, and the furthest distance between the fourth connecting portion 615 and the fastening portion 612 is equal to the height of the second fixing portion 216. Thus, when the fastening portion 612 is fixed to the base 2121 by the fastener 62, the first connecting portion 611 and the second connecting portion 613 are respectively fitted onto the first fixing portion 215 and the second fixing portion 216. Preferably, to increase the fatigue strength of the connector, the third connecting portion 614 is perpendicular to the first connecting portion 611 and the base 2121, and the fourth connecting portion 615 is perpendicular to the second connecting portion 613 and the base 2121. However, it is obviously not limited to this. Other angles are also possible, such as the first connecting part 611 being fitted onto the first fixing part 215 and the second connecting part 613 being fitted onto the second fixing part 216.

[0063] Please see Figure 6 or Figure 7 To facilitate the fixing of the first elastic element 51 and the second elastic element 52 to the housing 10, in one specific embodiment, the endoscope operating part 100 further includes two second connecting members 70. Specifically, the first elastic element 51 and the second elastic element 52 are respectively fixedly connected to the housing 10 via the two second connecting members 70. Specifically, both ends of the first elastic element 51 are fixed to one second connecting member 70 and the first fixing part 215, respectively. Both ends of the second elastic element 52 are fixed to one second connecting member 70 and the second fixing part, respectively. Specifically, the two second connecting members 70 are respectively fixed to the housing 10 at positions directly opposite the first opening 21a and the second opening 21b, so that when the endoscope operating part 100 is in its initial state, the first elastic element 51 and the second elastic element 52 naturally extend along the length direction of the endoscope operating part 100.

[0064] In one specific embodiment, the second connector 70 is a stud, one end of which is fixed to the housing 10 by threads, and the other end is provided with a ring. The first elastic element 51 or the second elastic element 52 is sleeved on the ring of the second connector 70.
