Description

Technical Field

[0001] The utility model relates to a locking mechanism and medical equipment with the locking mechanism. Background Art

[0002] In modern healthcare, the use of various medical devices is becoming increasingly widespread, playing a vital role in improving diagnostic accuracy and treatment efficiency. However, with the advancement of medical technology, higher demands are being placed on the user-friendly design and ease of use of medical devices. In practice, doctors and medical staff need to adjust the angle and position of medical devices based on the patient's specific condition and operational requirements to facilitate optimal operation and observation.

[0003] In the design of medical devices, flexible adjustment and secure locking of operating panels are key factors in improving device performance, enhancing medical staff efficiency, and ensuring patient safety. While existing medical devices offer certain adjustment capabilities, they often suffer from single locking mechanisms, complex operation, and high costs. Especially for medical devices that require simultaneous control of multiple motion modes (such as vertical movement and rotation), existing locking mechanisms often fail to meet the requirements for efficiency, reliability, and safety.

[0004] Furthermore, traditional locking mechanisms typically only control a single motion mode or require complex mechanical structures to control multiple motion modes. This not only increases the manufacturing cost and size of the device but also reduces the reliability of the locking mechanism. Furthermore, complex structures often mean increased maintenance requirements and potential safety hazards. Therefore, the design and manufacturing of medical devices urgently need a locking mechanism that can simultaneously control multiple motion modes while offering excellent reliability, safety, and cost-effectiveness. Utility Model Content

[0005] The present utility model was developed in response to the aforementioned problems. Its purpose is to provide a locking mechanism and a medical device incorporating such a locking mechanism, which, through a simple structure, can precisely control the relative movement between the components being locked, while exhibiting excellent reliability and safety. Furthermore, due to its simple structure, it not only effectively reduces the overall size and weight of the device, but also significantly reduces manufacturing costs. Furthermore, for operators of medical devices incorporating such a locking mechanism, adjustments to the device can be made more easily, improving the device's efficiency and user experience.

[0006] The utility model provides a locking mechanism and medical equipment with the locking mechanism.

[0013] Furthermore, the first component and the second component are provided with matching holes that match the locking shaft, and the locking shaft moves up and down inside the matching holes.

[0014] When the locking action is performed, the locking shaft descends and is inserted into the first component and the second component through the matching hole, thereby limiting the relative movement between the first component and the second component.

The through hole is formed into a slope structure with a depth gradually changing from shallow to deep. The locking shaft passes through the rotating base and the rotating trigger in sequence, and is fixed to the second fastener through the through hole. When the rotating trigger rotates, the second fastener rises or falls as the rotating ring rolls in the through hole, thereby driving the locking shaft to rise and fall.

[0052] According to an exemplary embodiment of the present invention, a locking mechanism is provided.

[0053] Figure 1 1 is a schematic diagram showing a locking mechanism 10 according to an exemplary embodiment of the present invention. Figure 1As shown, the locking mechanism 10 includes a locking shaft 1, a cap 11, and a rotary trigger 2. The locking shaft 1 is configured to pass through the rotary trigger 2 and be inserted into the first part P1 and the second part P2, which are external locking objects, to lock the relative movement between the first part P1 and the second part P2. The cap 11 and the locking shaft 1 are fixed to each other. The rotary trigger 2 is configured to be connected to an external control line 3 (shown by a dotted line in the figure) and is configured to rotate in response to the input of the control line 3. The cap 11 moves up and down with the rotation, thereby driving the locking shaft 1 to move up and down, thereby achieving the locking and release of the relative movement between the first part P1 and the second part P2.

[0054] The locking shaft 1 can be configured to move in different ways. For example, in some implementations, in order to limit the relative movement between the first component P1 and the second component P2 in the left-right direction and achieve locking and releasing in this direction, the cap 11 and the locking shaft 1 can be configured to move left-right. Specifically, the rotary trigger 2 rotates in response to the input of the control line 3, and the cap 11 moves in the left-right direction with this rotation, thereby driving the locking shaft 1 to move in the left-right direction, thereby achieving locking and releasing relative movement in the left-right direction. Alternatively, in order to limit the relative movement between the first component P1 and the second component P2 in the front-to-back direction and achieve locking and releasing in this direction, the cap 11 and the locking shaft 1 can be configured to move back-to-back. Specifically, the rotary trigger 2 rotates in response to the input of the control line 3, and the cap 11 moves in the front-to-back direction with this rotation, thereby driving the locking shaft 1 to move in the front-to-back direction, thereby achieving locking and releasing relative movement in the front-to-back direction.

[0055] In addition, despite Figure 1 It is shown that the rotary trigger 2 is connected to the external control line 3 , however, those skilled in the art should understand that the rotary trigger 2 can also be remotely controlled wirelessly.

[0056] like Figure 1 As shown, the first and second components P1 and P2 are provided with mating holes h1 and h2, respectively, which mate with the locking shaft 1. The locking shaft 1 moves up and down within the mating holes h1 and h2. During locking, the locking shaft 1 descends, inserting into the second component P2 and first component P1 sequentially through the mating holes h2 and h1, restricting relative movement between the first and second components P1 and P2. During release, the locking shaft 1 ascends, exiting the mating holes h1 and h2, allowing relative movement between the first and second components P1 and P2.

[0057] Specifically, for example, if the locking shaft 1 is configured to move up and down, when a locking action is performed in response to input from the control line 3, the locking shaft 1 descends, sequentially passing through the mating hole h2 provided in the second component P2 and the mating hole h1 provided in the first component P1, inserting into the second component P2 and the first component P1, thereby locking the relative movement between the first component P1 and the second component P2. If a release action is performed in response to input from the control line 3, the locking shaft 1 ascends, sequentially exiting through the mating hole h1 and the mating hole h2, releasing the locking mechanism 10 and allowing relative movement between the first component P1 and the second component P2. If the locking shaft 1 is configured to move left and right or forward and backward, the corresponding actions can be performed in a similar manner.

[0058] Furthermore, the relative movement between the first component P1 and the second component P2 may be relative rotation, vertical movement, or a combination of rotation and vertical movement. In the case of a combination of relative movement, rotational positioning may be performed first and then vertical movement locking, or vertical positioning may be performed first and then rotational locking.

[0059] In addition, the matching holes h1 and h2 can be set to various shapes, such as circular, oval, square, etc., as long as they can match the locking shaft 1. In some implementations, guide grooves, spiral grooves or protrusions can also be set in the matching holes h1 and h2 to guide the precise movement and positioning of the locking shaft 1. In addition, in some implementations, elastic parts such as springs or dampers can also be set in the matching holes h1 and h2 to provide buffering or auxiliary locking when the locking shaft 1 moves. In addition, in some implementations, elastic parts such as springs can also be set around the locking shaft 1. While maintaining the stable position of the locking shaft, it can also assist in locking and releasing actions, reduce operating force, and provide buffering and shock absorption, reduce wear, and extend the service life of the components.

[0060] The locking mechanism 10 of this embodiment can precisely control the relative movement between locked components through a simple structure, achieving multi-dimensional motion control with excellent reliability and safety. Furthermore, its simple structure effectively reduces the overall size and weight of the device while significantly lowering manufacturing costs.

[0061] Two exemplary embodiments of this embodiment are described in detail below.

[0062] Example 1.

[0063] Figure 2 This is an exploded perspective view of the locking mechanism 10A according to the first embodiment. Figure 2 A specific embodiment of the locking mechanism 10 according to the above embodiment is shown. Figure 2The external locking objects used in conjunction with the locking mechanism 10A, namely the first component P1 (not shown) and the second component P2 (not shown), are omitted in order to more clearly illustrate the structure and function of the locking mechanism 10A.

[0064] like Figure 2 As shown, similarly to the locking mechanism 10, the locking mechanism 10A includes a locking shaft 1A, a cap 11A ( Figure 2 The upper cover 4A and fastener S2 in the lock and the rotary trigger 2A. The locking shaft 1A is set to pass through the rotary trigger 2A. The cap 11A and the locking shaft 1A are fixed to each other. The rotary trigger 2A is set to be connected to the external control line 3A, and rotates in response to the input of the control line 3A. The cap 11A moves up and down with the rotation, thereby driving the locking shaft 1A to move up and down, realizing the locking and release of the relative movement between the first part P1 and the second part P2 as the locking objects. Regarding the connection between the rotary trigger 2A and the external control line 3A, for example, Figure 2 As shown, a control wire hanging hole h can be provided on the rotary trigger 2A. By snapping a ball provided at one end of the control wire 3A into the control wire hanging hole h, one end of the control wire 3A is secured to the rotary trigger 2A. However, the present invention is not limited to this embodiment. As long as the control wire 3A can be used to control the rotary trigger 2A so that the rotary trigger 2A rotates in response to input from the control wire 3A, any fixing method or wireless control method known in the art can be used.

[0065] Furthermore, if Figure 2 As shown, the locking mechanism 10A also includes an upper cover 4A and a rotating base 5A. The upper cover 4A is secured to the rotating base 5A via fasteners S1, thereby rotatably clamping the rotary trigger 2A between the upper cover 4A and the rotating base 5A. The rotating trigger 2A, the upper cover 4A, and the rotating base 5A are provided with holes for the locking shaft 1A to pass through. The locking shaft 1A is inserted through the upper cover 4A, the rotating trigger 2A, and the rotating base 5A in sequence and secured to the upper cover 4A via fasteners S2. The upper cover 4A and fasteners S2 form a cap 11A.

[0066] Fasteners S1 and S2 can be screws, pins, etc. known in the art. However, in some implementations, a stepped screw can be used for fastener S1. A stepped screw generally includes two threaded portions of different diameters, the larger thread being used to secure the upper cover 4A, while the smaller thread is used to rotate the base 5A. This design can provide a stronger fixing force, ensuring that when the rotary trigger 2A rotates, the upper cover 4A remains firmly fixed on the rotating base 5A, and no relative movement occurs between the two. In addition, in some implementations, the fastener S2 can also be a stepped screw to provide a more reliable fixation, reduce the risk of loosening due to vibration or impact, and improve the reliability of the entire locking mechanism.

[0067] Furthermore, if Figure 2 As shown, the surface of the rotary trigger 2A is provided with a plurality of grooves g1, which are formed as inclined grooves with increasing depth. Balls are disposed in each of the grooves g1. The rolling motion of the balls within the grooves g1 propels the upper cover 4A upward or downward, thereby driving the locking shaft 1A upward or downward.

[0068] Specifically, by forming the multiple grooves g1 into inclined grooves, the balls move along the inclined surfaces as they roll within the grooves g1, guiding the upper cover 4A as it rises or falls. When raising the upper cover 4A, the balls roll along the inclined surfaces of the grooves g1 from a deeper position to a shallower position; when lowering the upper cover 4A, the balls roll along the inclined surfaces of the grooves g1 from a shallower position to a deeper position. By providing the inclined grooves g1 and the balls used with them, the operator operating the locking mechanism 10A using the control wire 3A can achieve significant movement of the upper cover 4A with only a small amount of force.

[0069] Figure 2 The figure shows a case where three grooves g1 are formed on the surface of the rotary trigger 2A, and each groove g1 is provided with a ball, but the present invention is not limited to this. In some implementations, two or more grooves g1 can be provided, depending on the actual surface conditions of the rotary trigger 2A and usage requirements. In addition, depending on the length of the groove and the adjustment requirements, more than two balls can be placed in each groove, thereby increasing the contact points, further reducing friction and improving adjustment accuracy. Alternatively, different numbers of balls can be placed in different grooves to achieve different force and speed transmission, improve adjustment accuracy, and optimize the performance of the locking mechanism.

[0070] Furthermore, in some implementations, one or more grooves g2 are also provided on the surface of the rotating base 5A. The grooves g2 are formed as horizontal grooves with a uniform depth, and balls are placed in the grooves g2. Figure 2 In the figure, a circular groove g2 is formed on the surface of the rotating base 5A, and three balls are placed in the groove g2. However, the present invention is not limited to this. In some implementations, more than two grooves g2 can be provided, and one ball can be placed in each groove g2, or more balls can be placed in each groove g2.

[0071] By creating horizontal grooves g2 on the surface of the rotating base 5A and placing balls within them, the rolling motion of the balls within the grooves g2 replaces the sliding friction between the upper and lower components, significantly reducing the coefficient of friction and making the rotating base 5A rotate more smoothly. Furthermore, the pressure from the upper cover 4A is distributed across multiple points on the rotating base 5A, reducing localized pressure concentration and improving the load-bearing capacity of the entire structure. This significantly reduces component wear, enhances the durability and reliability of the entire locking mechanism 10A, and ultimately helps reduce maintenance costs over long-term use.

[0072] Furthermore, in some implementations, the locking mechanism 10A further includes an elastic member S3, such as a spring, disposed around the locking shaft 1A. This elastic member S3 maintains the stable position of the locking shaft 1A, preventing loosening due to vibration and maintaining locking stability. Furthermore, it provides cushioning and shock absorption, reducing wear and extending service life. Furthermore, it assists in locking and releasing operations, improving response speed and, accordingly, further reducing the operator's operating force when operating the control line to lock and release, thereby enhancing operational convenience.

[0073] According to the locking mechanism 10A of the first embodiment, when the locking action is performed in response to input from the control line 3A, the rotary trigger 2A rotates, and the upper cover 4A descends as the ball provided in the rotary trigger 2A rolls toward the deeper side in the groove g1. This in turn drives the locking shaft 1A fixed to the upper cover 4A downward, thereby locking the relative movement between the first and second components to be locked. Conversely, when the release action is performed in response to input from the control line 3A, the rotary trigger 2A rotates, and the upper cover 4A ascends as the ball provided in the rotary trigger 2A rolls toward the shallower side in the groove g1. This in turn drives the locking shaft 1A fixed to the upper cover 4A upward, thereby releasing the locking mechanism 10A and allowing relative movement between the first and second components to be locked.

[0074] The locking mechanism 10A according to the first embodiment, in addition to achieving the technical effects achieved by the locking mechanism 10 described above, also has the following technical effects: First, by providing a sloped groove g1 with varying depths on the surface of the rotary trigger 2A and allowing the ball to roll within the groove g1, precise control of the raising or lowering of the upper cover 4A can be achieved, thereby finely adjusting the lifting and lowering of the locking shaft 1A. Second, the rolling motion of the ball within the sloped groove g1 is smoother than direct sliding, reducing friction and wear, and improving the durability of the locking mechanism. The use of the ball also reduces the direct contact area between the upper cover 4A and the rotating base 5A, reducing friction and making movement smoother. Third, the sloped design of the groove g1 allows a smaller rotational force to be converted into a larger vertical motion force, thereby effectively driving the lifting and lowering of the locking shaft 1A. This further reduces the operating force required by the operator using the control line 3A to operate the locking mechanism 10A, further improving the efficiency of the locking mechanism and the user experience.

[0075] Example 2.

[0076] Figure 3 This is an exploded perspective view showing a locking mechanism 10B according to the second embodiment. Figure 3 Another specific embodiment of the locking mechanism 10 according to the above embodiment is shown. Figure 3 The external locking objects used in conjunction with the locking mechanism 10B, namely the first component P1 (not shown) and the second component P2 (not shown), are omitted in order to more clearly illustrate the structure and function of the locking mechanism 10B.

[0077] like Figure 3 As shown, similar to the locking mechanism 10, the locking mechanism 10B includes a locking shaft 1B, a cap 11B (i.e. Figure 3 The locking shaft 1B is configured to pass through the rotating trigger 2B. The cap 11B and the locking shaft 1B are fixed to each other. The rotating trigger 2B is configured to be connected to an external control line 3B and is configured to rotate in response to the input of the control line 3B. The cap 11B moves up and down with the rotation, thereby driving the locking shaft 1B to move up and down, thereby achieving the locking and release of the relative movement between the first part P1 and the second part P2 as the locking objects. Regarding the connection between the rotating trigger 2B and the external control line 3B, for example, Figure 3 As shown, a control wire groove can be provided on the rotary trigger 2B, and a ball provided at one end of the control wire 3B can be inserted into the control wire groove to secure one end of the control wire 3B to the rotary trigger 2B. However, the present invention is not limited to this embodiment. As long as the control wire 3B can be used to control the rotary trigger 2B so that the rotary trigger 2B rotates in response to input from the control wire 3B, any fixing method or wireless method known in the art can be used.

[0078] Furthermore, if Figure 3 As shown, the locking mechanism 10B further includes a rotating base 5B, to which the rotary trigger 2B is secured via a fastener s1. The rotary trigger 2B is provided with an arcuate through-hole t1, which is configured to allow the fastener s2 to pass through. Furthermore, the rotary trigger 2B is configured to rotate relative to the rotating base 5B about the fastener s2. The fastener s2 forms a cap 11B.

[0079] The locking shaft 1B sequentially passes through the rotating base 5B and the rotating trigger 2B, and is secured to the fastener s2 via the through-hole t1. Furthermore, the locking mechanism 10B further includes a rotating ring r1, which is positioned so as to surround the fastener s2 and be located between the fastener s2 and the through-hole t1. Furthermore, the through-hole t1 is formed into a sloped structure with a gradually increasing depth from shallow to deep. The fastener s2 is positioned so as to sequentially pass through the through-hole t1, interposed between the rotating ring r1 and be secured to the locking shaft 1B. When the rotating trigger 2B rotates, the rotating ring r1 rolls within the sloped through-hole t1, causing the fastener s2 to rise or fall, thereby driving the locking shaft 1B up and down, thereby locking and releasing the relative movement between the components being locked.

[0080] Fasteners s1 and s2 can be screws, pins, or the like, as are known in the art. Preferably, they can be stepped screws. Using stepped screws, with two threaded sections of different diameters, provides a more secure fixation, reduces the risk of loosening due to vibration or impact, and improves the reliability of the entire locking mechanism.

[0081] In addition, regarding the through hole t1, it can be further specifically configured according to different application requirements. For example, the slope can be adjusted by changing the angle or shape of the ramp structure to achieve different lifting speeds and forces. In some implementations, the through hole t1 may also include guide grooves, etc. to ensure the precise guidance of the step screw s2 and the rotating ring r1 during movement to prevent lateral movement or falling off. In addition, in some implementations, special materials or coatings can be used for the through hole t1 to improve the durability and reliability of the locking mechanism in high temperature, low temperature, corrosive or high vibration environments.

[0082] Furthermore, in some implementations, the locking mechanism 10B further includes an elastic member S3, such as a spring, disposed around the locking shaft 1B. Similar to the locking mechanism 1A, this elastic member S3 can firstly maintain the stable position of the locking shaft 1B, preventing loosening due to vibration and maintaining locking stability. Secondly, it can provide cushioning and shock absorption, reducing wear and extending service life. Thirdly, it can assist in locking and releasing operations, improving response speed, and correspondingly further reducing the operator's operating force when operating the control line to lock and release, thereby improving operational convenience.

[0083] According to the locking mechanism 10B of the second embodiment, when a locking action is performed in response to input from the control line 3B, the rotary trigger 2B rotates, causing the fastener s2 (rotating ring r1) to slide along the through hole t1 provided in the rotary trigger 2B. As the rotating ring r1 moves from the shallower side of the through hole t1 to the deeper side, the fastener s2 descends, thereby lowering the locking shaft 1B fixed thereto, thereby locking relative movement between the first and second components to be locked. Conversely, when a release action is performed in response to input from the control line 3B, the rotary trigger 2B rotates, causing the fastener s2 (rotating ring r1) to slide along the through hole t1 provided in the rotary trigger 2B. As the rotating ring r1 moves from the deeper side of the through hole t1 to the shallower side, the fastener s2 ascends, thereby ascending the locking shaft 1B fixed thereto, thereby releasing the locking mechanism 10B and allowing relative movement between the first and second components to be locked.

[0084] The locking mechanism 10B of Example 2, in addition to achieving the technical effects achieved by the locking mechanism 10 described above, also has the following technical effects: First, compared with the locking mechanism 10A of Example 1, it has a simpler structure and lower cost, further reducing the overall size and weight of the device and further reducing manufacturing costs. Second, the sloped structure of the through hole t1 provided in the rotary trigger 2B converts a smaller rotational force into a larger vertical motion force, thereby effectively driving the lifting and lowering of the locking shaft 1B. This further reduces the operating force required by the operator operating the locking mechanism 10B using the control line 3B, further improving the efficiency of the locking mechanism and the user experience.

[0085] According to yet another exemplary embodiment of the present invention, a medical device is provided.

[0086] Figure 4 A top view of a medical device 100 according to yet another exemplary embodiment of the present invention is shown. Figure 5 1 is a partial cross-sectional view showing the medical device 100. Figure 4 and Figure 5The medical device 100 according to this embodiment will be described in detail. The same or similar structures and effects as those described above will not be described in detail here.

[0087] like Figure 4 As shown, medical device 100 includes a rotating unit 101, locking mechanisms 10 (locking mechanisms 10A and 10B), an operating panel 102, and a column (not shown). Operating panel 102 has a base 103. The column is disposed below base 103 of the operating panel and supports the operating panel. Rotating unit 101 is a component for rotating the operating panel when operated and is secured to base 103 using fasteners such as screws.

[0088] The locking mechanism 10 is fixed to the base 103 by fasteners such as screws, and is configured so that its locking shaft 1 (1A, 1B) passes through the rotary trigger 2 (2A, 2B) and is then inserted into the rotating portion 101. As described above, the rotary trigger 2 (2A, 2B) is connected to a control line and can rotate in response to input from the control line. This rotation causes the locking shaft 1 (1A, 1B) to move up and down, thereby locking and releasing the rotating portion 101.

[0089] Below, refer to Figure 5 The structure of the rotating part 101 and its cooperation with the locking mechanism 10 are described in detail. Figure 5 In order to make those skilled in the art understand the present invention more clearly, only the main structures of the rotating portion 101 and the locking mechanism 10 (10A, 10B) are shown, and the illustration of the operation panel (base) and the column is omitted.

[0090] like Figure 5 As shown, the rotating unit 101 is composed of an upper plate 101-1, a plate base 101-2, and a lower plate 101-3 stacked together. When the rotating unit 101 rotates, the upper plate 101-1 and the lower plate 101-3 rotate relative to the plate base 101-2. In other words, the upper plate 101-1 and the lower plate 101-3 constitute a first component, and the plate base 101-2 constitutes a second component. The rotation of the upper plate 101-1 and the lower plate 101-3 relative to the plate base 101-2 constitutes relative movement between the first component and the second component.

[0091] Furthermore, corresponding holes are formed on the upper plate 101-1, the plate base 101-2, and the lower plate 101-3 to match the locking shaft 1 (1A, 1B). The locking shaft 1 (1A, 1B) moves up and down within the matching holes to lock and release the rotating part 101.

[0092] Specifically, when the locking mechanism 10 (10A, 10B) rotates in response to the input of the control line to perform a locking action, the locking shaft 1 (1A, 1B) descends, passes through the upper disk 101-1 and the disk base 101-2 in sequence through the respective matching holes, and is inserted into the lower disk 101-3, thereby restricting the upper disk 101-1 and the lower disk 101-3 from rotating relative to the disk base 101-2, thus completing the locking. Conversely, when the locking mechanism 10 (10A, 10B) rotates in response to the input of the control line to perform a release action, the locking shaft 1 (1A, 1B) ascends and exits from the respective matching holes, thereby allowing the upper disk 101-1 and the lower disk 101-3 to rotate relative to the disk base 101-2, thus completing the release.

[0093] In some implementations, the medical device 100 further includes a lifting unit disposed within the column, configured to operate the operating panel to cause the lifting movement. The lifting unit is connected to a rotary trigger of the locking mechanism 10 (10A, 10B) via a cable. When the rotary trigger rotates in response to input from a control cable, it pulls out and rewinds the cable, thereby pulling the lifting unit to lock and release the lifting unit.

[0094] Specifically, in the medical device 100, the lifting part may include a gas spring. One end of the cable is connected to the rotary trigger of the locking mechanism 10 (10A, 10B), and the other end is connected to the gas spring of the lifting part. When the rotary trigger rotates in response to the input of the control line to perform a locking action, the cable connecting the rotary trigger and the gas spring is rewound as the rotary trigger rotates, locking the gas spring, and thus locking the lifting part. Conversely, when the rotary trigger rotates in response to the input of the control line to perform a release action, the above-mentioned cable is pulled out as the rotary trigger rotates, releasing the gas spring, and thus releasing the lifting part.

[0095] In addition to the technical effects of the aforementioned embodiments, this embodiment also has the following effects: When a lifting portion is provided, the locking mechanism 10 (10A, 10B) can simultaneously lock and release the rotational motion of the rotating portion and the lifting motion of the lifting portion, thereby enabling simultaneous control of both motion modes through a simple structure, significantly reducing the overall size and manufacturing cost of the medical device and improving the reliability of the medical device. Furthermore, for operators operating medical devices equipped with this locking mechanism, adjustments to the medical device can be made more easily, thereby improving the efficiency of use of the medical device and the user experience.

[0096] The locking mechanism and medical device having the same according to the present invention have been described above. However, the structures shown in the above exemplary embodiments are merely examples of the present invention and may be combined with other known technologies, or portions of the structures may be omitted or modified without departing from the spirit of the present invention.

[0097] Furthermore, the present invention can freely combine the various embodiments, modify any structural elements of the various embodiments, or omit any structural elements of the various embodiments within the scope of the present invention.
