[0038] See also Figure 1 , Figure 1 1 shows an in-hole introduction device according to an embodiment of the present disclosure. In some embodiments, the in-hole introduction device 100 includes an operating handle 110 ( Fig. 9 The in-hole introduction device 100 may be an endoscope or other types of instruments.

[0039] In some embodiments, the in-hole introduction device 100 includes a gripping portion 120 and a key base 1. The gripping portion 120 includes a first gripping portion 2 and a second gripping portion 4. The first gripping portion 2 and the key base 1 may be split structures and may be assembled and fixed; the first gripping portion 2 and the second gripping portion 4 may be split structures and may be assembled and fixed.

[0040] The first grip portion 2 has a user-facing surface 21. The first grip portion 2 defines a long axis direction and a user-facing direction. Specifically, the first grip portion 2 may define a long axis L, such as Figure 1 As shown, the long axis L is substantially parallel to the Z-axis direction, and the direction of the long axis L is the long axis direction. The user-facing direction is substantially parallel to the X-axis direction. When the operator holds the first grip portion 2 with one hand, the thumb can be placed on the user-facing surface 21; and depending on the posture of the wrist, arm, etc., the user-facing surface 21 is not necessarily facing the operator's chest.

[0041] Exemplarily, the first grip portion 2 may include at least one key. The key base 1 may include at least one key, such as a first key 201. It should be understood that the key may be set as a button, a dial button, a push button or even a knob. In the embodiment of the present disclosure, the key may be set as a button.

[0042] The button base 1 includes a base body 10 and a first button 201. The first button 201 can be one of the aforementioned buttons. Exemplarily, the base body 10 can be a shell. The first button 201 is disposed on the base body 10 and exposed outside the base body 10.

[0043] Combination Figure 2 The base body 10 has a connecting surface 11 , a first surface area 12 , a second surface area 13 and a third surface area 14 .

[0044] The connection surface 11 is connected to one end of the first holding portion 2. The connection surface 11 can also be used to define the long axis L, and the circumference of the connection surface 11 is the direction around the long axis L. After the key base 1 and the first holding portion 2 are connected, the connection surface 11 may not be exposed. The surface of the key base 1 can be divided into different surface areas according to the difference in position or shape.

[0045] The first surface area 12 and the second surface area 13 are arranged along the circumference of the connecting surface 11, and the first surface area 12 and the second surface area 13 are arranged opposite to each other at the two ends of the connecting surface 11. The first surface area 12 and the second surface area 13 are opposite to each other along the X-axis direction. The first surface area 12 is connected to the user-facing surface 21. The third surface area 14 is located at an end of the second surface area 13 that is opposite to the first gripping portion 2. The third surface area 14 and the connecting surface 11 are arranged opposite to each other along the Z-axis direction, for example, Figure 2 As shown, the third surface area 14 is the top surface of the base body 10 .

[0046] The third surface area 14 is inclined relative to the long axis direction, and the third surface area 14 is opposite to the side where the first surface area 12 is located along the user-opposing direction. When the key seat 1 is used, the end of the third surface area 14 facing the second surface area 13 is the end facing the index finger. In the inclined third surface area 14, the end facing the index finger has a shorter distance relative to the first grip portion 2, while the end of the third surface area 14 facing the first surface area 12 can have a longer distance relative to the first grip portion 2. The index finger can more smoothly bypass the end of the third surface area 14 facing the second surface area 13 and then rest on the third surface area 14. In addition, the third surface area 14 can have a larger projection area along the X-axis direction, realizing a larger operating space.

[0047] The side where the second surface area 13 is located is the front side, and the side where the first surface area 12 is located is the rear side. The front end of the third surface area 14 is low and the rear end is high.

[0048] The first button 201 is disposed at the third surface area 14. Exemplarily, the first button 201 has a first pressing axis m, and the first button 201 can be pressed along the direction of the first pressing axis m. The first pressing axis m is inclined toward the front side relative to the long axis L. Exemplarily, the angle α between the first pressing axis m and the long axis L can satisfy 0°<α<90°, for example, 0°<α<45°. Optionally, the angle α is 10°, 15°, 20° or 25°.

[0049] refer to Figures 1 to 3 In the in-hole introduction device 100 provided in the embodiment of the present disclosure, the first gripping portion 2 can be held by one hand, such as the left hand. In other embodiments, a gripping portion that can be held by one hand of the right hand can be designed. The button seat 1 has an ingenious structure and can be arranged on the first gripping portion 2. The button seat 1 is used to form an easy-to-use endoscope.

[0050] The in-hole introduction device 100 provided in the embodiment of the present disclosure is comfortable to use. By setting the third surface area 14 of the key base 1 to be inclined relative to the long axis direction, the first key 201 at the third surface area 14 is easy to be operated by the index finger. The user can also use the index finger to operate different keys, and the inclined third surface area 14 facilitates the transfer of the index finger between the key base 1 and the front side of the first gripping portion 2.

[0051] In some embodiments, the second surface area 13 and the third surface area 14 are respectively configured as curved surfaces. In this way, the second surface area 13 and the third surface area 14 can better absorb manufacturing tolerances, and the third surface area 14 can better ensure that its actual shape meets design expectations and ensures the comfort of use of the actual product.

[0052] Exemplarily, the third surface area 14 is configured as a curved surface with a convex middle portion. The first button 201 may be located in the middle of the third surface area 14. The third surface area 14 has a section A. The section A is perpendicular to the first pressing axis m, and then the section A is inclined relative to the long axis L. The section at any position of the third surface area 14 may be inclined toward the front side relative to the long axis L.

[0053] Exemplarily, the second surface area 13 is configured as a curved surface with a convex middle portion. The second surface area 13 is located on the lower side of the section A along the Z-axis direction. The second surface area 13 as a whole is generally facing the front side. Exemplarily, the key seat 1 includes a second key 202. The second key 202 is arranged at the second surface area 13, for example, at the middle position of the second surface area 13. The second key 202 may have a second pressing axis n. The direction of the second pressing axis n may be the normal direction of the second surface area 13 at that location. The angle between the second pressing axis n and the major axis L may be between 0° and 90°, for example, between 45° and 90°. Optionally, the angle between the second pressing axis n and the major axis L is 50°, 55°, 60° or 65°.

[0054] In some embodiments, the second surface area 13 and the third surface area 14 are connected in arc. The second surface area 13 and the third surface area 14 can be used to be smoothly swiped by fingers, which helps to reduce discomfort during operation. Exemplarily, the second surface area 13 and the third surface area 14 are used to form an integrated curved surface, and the curvature of the curved surface at the first button 201 and the curvature at the second button 202 can be different.

[0055] In some embodiments, the second surface area 13 and the third surface area 14 are connected smoothly, and the two can be connected by a rounded corner. The seat body 10 also has a fourth surface area 15 and a fifth surface area (not shown), which are arranged along the circumference of the connecting surface 11, and the fourth surface area 15 and the fifth surface area are arranged opposite to each other.

[0056] refer to Figure 1 and Figure 3 The first grip portion 2 has a user facing surface 21, a palm configuration surface 22, and a button configuration surface 23. The connection surface 11 of the button seat 1 can be called a first connection surface, and then the first grip portion 2 can have a second connection surface. The second connection surface is used to be connected to the first connection surface. Exemplarily, the user facing surface 21 can be called a sixth surface area, the palm configuration surface 22 can be called a seventh surface area, and the button configuration surface 23 can be called an eighth surface area.

[0057] The user facing surface 21, the palm configuration surface 22 and the button configuration surface 23 are sequentially arranged along the circumferential direction of the long axis L. The fourth surface area 15 corresponds to the palm configuration surface 22 of the first grip portion 2; illustratively, the first surface area 12 corresponds to the user facing surface 21, and the second surface area 13 corresponds to the button configuration surface 23 of the first grip portion 2.

[0058] The fourth surface area 15 is smoothly connected to the third surface area 14, which helps the index finger tip to press the first button 201, and helps the distal interphalangeal joint of the index finger to have a comfortable touch when the pressing action is achieved. The fourth surface area 15 can also be smoothly connected to the second surface area 13; the fourth surface area 15 can also be smoothly connected to the first surface area 12.

[0059] For example, the first surface area 12 and the second surface area 13 are respectively suitable for smoothly connecting to the surface of the first grip portion 2, which helps to avoid the thumb or index finger from feeling awkward. In general, the connection between the first grip portion 2 and the key base 1 is smooth, which is conducive to giving the index finger and thumb a comfortable touch.

[0060] Exemplarily, the first surface area 12 is smoothly connected to the user facing surface 21 , the second surface area 13 is smoothly connected to the button configuration surface 23 , and the fourth surface area 15 is smoothly connected to the palm configuration surface 22 .

[0061] In some optional embodiments, the seat body 10 and the first holding portion housing 20 of the first holding portion 2 can realize an integrated structure, and then the connecting surface 11 is a cross section of the long axis L to divide the key seat 1 and the first holding portion 2. Figure 2 As shown, the connection surface 11 can be inclined relative to the long axis L, and the connection surface 11 has a longer perimeter, and then the inner side of the connection surface 11 can be used to open a larger assembly area. The rear end of the connection surface 11 along the X-axis direction is lower, and illustratively, the angle between the connection surface 11 and the first surface area 12 is an acute angle.

[0062] refer to Figure 2 In some embodiments, the first surface area 12 is inclined relative to the long axis direction, and the first surface area 12 is opposite to the side where the connecting surface 11 is located along the long axis direction. The button base 1 includes a third button 203, and the third button 203 is located at the first surface area 12. Figure 4 The thumb of the operator can conveniently operate the third button 203, and the thumb can have enough bending space in the XZ plane. The pressing axis of the third button 203 can be roughly parallel to the X-axis direction, or can be inclined relative to the X-axis direction, so that the thumb can press the third button 203 obliquely downward.

[0063] refer to Figures 1 to 4 For example, the user can hold the operating handle 110 of the hole introduction device 100 with the left hand. In some embodiments, the operating handle 110 includes a button seat 1, a first gripping portion 2, a supporting portion 3, a second gripping portion 4 and a locking portion 5. The button seat 1, the supporting portion 3 and the second gripping portion 4 are respectively connected to the first gripping portion 2.

[0064] Exemplarily, the second holding portion 4 can be used to define a long axis L, and a cross section of a distal end of the second holding portion 4 can be approximately circular, with the long axis L passing through the center of the circle.

[0065] The support portion 3 may include a support portion housing 301. The support portion housing 301 is used to install the cable 9. The support portion housing 301 may be provided as an integrated structure with the first handle portion housing 20, and the internal installation space of the support portion housing 301 may be connected to the internal installation space of the first handle portion housing 20. The cable 9 is passed through the support portion housing 301. In some embodiments, the support portion housing 301 may be relatively long, and the user's hand may directly hold the support portion 3; in other embodiments, the length of the support portion housing 301 is appropriate, and the user's hand may also hold a portion of the cable 9.

[0066] The proximal end of the second gripping portion 4 is connected to the distal end of the first gripping portion 2; the locking portion 5 is connected to the distal end of the second gripping portion 4. The locking portion 5 can be used to lock the second gripping portion 4 with the insertion portion 6 ( Fig. 9 ). It can be understood that the introduction direction of the hole introduction device 100 can be set along the long axis direction of the long axis L, and the operating handle 110 and each component of the insertion part 6 can have a proximal end and a distal end relative to the user. The insertion part 6 can be used to be at least partially introduced into the hole, and the operating handle 110 itself is generally not introduced into the hole.

[0067] like Figure 1 and Figure 4 As shown, exemplarily, the in-hole introduction device 100 further includes a support portion 3. The support portion 3 is connected to the palm configuration surface 22 of the first grip portion 2, and the support portion 3 and the first grip portion 2 define a thumb space 303. The support portion 3 protrudes from the user-facing surface 21 along the radial direction of the long axis L in the X-axis direction shown in the figure. When the user holds the first grip portion 2 and the second grip portion 4, the thumb of his left hand can be fitted in the thumb space 303. Of course, the user can also independently choose to hold the device at a position farther from the support portion 3, for example, or place the thumb on the palm configuration surface 22.

[0068] refer to Figure 4 For example, the first grip portion 2 may include a fourth button 204, a fifth button 205, and a sixth button 206 arranged from top to bottom, and these buttons may be arranged on the button configuration surface 23. The user may use the ring finger and the little finger of the left hand to hold the second grip portion 4 and part of the first grip portion 2, the metacarpal bone may be against the palm configuration surface 22 and a part of the second grip portion 4, the thumb may be against the user facing surface 21 and can operate the third button 203, and the tiger's mouth may be fitted in the tiger's mouth space 303. The user may use the middle finger of the left hand to operate the sixth button 206, and the middle finger may also be used to operate the fifth button 205. Figure 4As shown, the index finger of the user can switch between the second button 202 and the fourth button 204 , for example, the user can operate the second button 202 with the index finger.

[0069] like Figure 5 As shown, the index finger of the user can switch between the first button 201, the second button 202 and the fourth button 204. For example, the user can use the index finger to operate the first button 201. Since the third surface area 14 is inclined to the front side, when the index finger switches from the second button 202 to the first button 201, the movement is smooth and has a short movement stroke. In addition, the index finger partially abuts against the support part 3, but the index finger can at least contact the front half of the first button 201.

[0070] Exemplarily, the pressing direction of the first button 201 points to the space between the thumb and the base 303, which is convenient for the index finger to press the first button 201. Exemplarily, the pressing direction of the second button 202 can also point to the space between the thumb and the base 303, which is convenient for the index finger to press the second button 202.

[0071] refer to Figure 5 and Figure 6 In some embodiments, the support portion 3 of the in-hole introduction device 100 is connected to the palm configuration surface 22 of the first gripping portion 2, and the support portion 3 defines the index finger root contact position 302. The index finger root contact position 302 is located at the far side of the support portion 3 along the long axis direction. Specifically, the projection of the index finger root contact position 302 on the XZ plane may fall on the long axis L. The distance between the index finger root contact position 302 and the support portion 3 is 6 mm to 10 mm, for example, 7 mm or 9 mm. Such a configuration can ensure that when the operator's finger root is against the index finger root contact position 302, the side of the index finger is against the support portion 3, which helps to hold the gripping portion 120 comfortably and stably.

[0072] The index finger root contact position 302 may face the first key 201 along the long axis direction. The key base 1 includes a second key 202 located in the second surface area 13. In the plane defined by the long axis direction and the user-facing direction, the distance between the second key 202 and the index finger root contact position 302 is the same as the distance between the first key 201 and the index finger root contact position 302. Such a configuration is conducive to the index finger being able to easily switch to operate different keys by swinging without substantially changing the placement position of the finger root. The internal space of the key base 1 can be expanded sufficiently to facilitate the assembly of internal parts.

[0073] For example, when measuring the position of a key, the contact surface of the key for contacting a finger may be measured. For example, the center position of the contact surface may be measured. The contact surface may be a plane or a curved surface.

[0074] Exemplarily, the first distance between the second button 202 and the index finger root contact position 302 is smaller than the second distance between the first button 201 and the index finger root contact position 302. Exemplarily, the difference between the second distance and the first distance is smaller than 10 mm, such as 8 mm, 7 mm or 5 mm. Exemplarily, the third distance between the fourth button 204 and the index finger root contact position 302 is smaller than the first distance between the second button 202 and the index finger root contact position 302. Exemplarily, the difference between the first distance and the third distance is smaller than 10 mm, such as 9 mm, 7 mm or 6 mm. By making the farther buttons closer to the index finger root contact position 302, it is possible to facilitate the index finger to switch different buttons.

[0075] The index finger root contact position 302 can be used to abut against the index finger root of the operator. Of course, the actual holding position can still be adjusted. For the structure of the index finger, the end of the third knuckle corresponding to the metacarpophalangeal joint is the finger root, but it can be considered that the finger root is covered by the palm skin. Figure 1 and Figure 6 , the index finger base contact position 302 may belong to the palm configuration surface 22 .

[0076] Exemplarily, the second surface area 13 is inclined relative to the long axis direction, and the second surface area 13 is opposite to the side where the connecting surface 11 is located along the long axis direction. The index finger can conveniently operate the second button 202. In addition, it is also helpful to reduce the obstruction of the index finger when transferring between the first button 201 and the fourth button 204.

[0077] Exemplarily, the distance from the first button 201 to the index finger root contact position 302 along the long axis direction is less than or equal to 5 mm. When the in-hole introduction device 100 is used, the metacarpal joint of the index finger can be located at the index finger root contact position 302, and the fingertip of the index finger can operate the first button 201. Not only can a large hand operate the button seat 1 and the first gripping portion 2 provided in the embodiment of the present disclosure with one hand, but also a small hand can operate the button seat 1 and the first gripping portion 2 with one hand because the third surface area 14 is tilted forward, and can press the first button 201. When using the same hand, the posture will also be adjusted to prevent muscle relaxation, and the hands in different postures can operate the first button 201 well.

[0078] Exemplarily, the index finger base contact position 302 and the base space 303 are arranged along the circumference of the first grip portion 2. The index finger base contact position 302 is closer to the first button 201 than the base space 303 along the long axis direction. Figure 6 The distal end of the support portion housing 301 is formed into an upward curve, and the portion thereof away from the user-facing surface 21 gradually rises.

[0079] Generally speaking, it is expected that the curved surface of the index finger is substantially parallel to the pressing direction of the first button 201. However, in some cases, the curved surface of the index finger may also be deflected to a certain extent relative to the pressing direction of the first button 201, and the index finger may operate the first button 201 by means of scratching and pressing. The fourth surface area 15 may be smoothly connected to the second surface area 13, the fourth surface area 15 may be smoothly connected to the third surface area 14, and the second surface area 13 may be smoothly connected to the third surface area 14, which helps prevent loose wrists and fingers, and the user can operate the first button 201 in a relatively comfortable manner.

[0080] In some embodiments, the angle between the pressing direction of the first button 201 and the pressing direction of the second button 202 is less than 45°. The button base 1 has a compact structure, which is convenient for fingers to press different buttons and can avoid excessive changes in the pressing direction of fingers.

[0081] refer to Figure 7 and Figure 8 In some embodiments, the second surface area 13 and the third surface area 14 are configured as mutually deflected planes. The deflection of the second surface area 13 and the third surface area 14 can make the operator feel a relatively obvious difference in the position of the finger during blind operation, which helps to more accurately locate the first key 201.

[0082] Exemplarily, the second surface area 13 faces away from the first gripping portion 2. The inner angle between the second surface area 13 and the third surface area 14 may be less than 180° and greater than 135°. Exemplarily, along the long axis L from the third surface area 14 to its distal side, the size of the seat body 10 becomes larger and larger.

[0083] refer to Figure 1 and Fig. 9 The intra-hole introduction device 100 provided in the embodiment of the present disclosure may be an endoscope.

[0084] In some embodiments, the in-hole introduction device 100 includes a button seat 1, a first holding portion 2, a supporting portion 3, a second holding portion 4, a locking portion 5 and an insertion portion 6; the in-hole introduction device 100 can be connected to a connector 7 via a cable 9, and then connected to a matching device 8 to form an in-hole introduction system.

[0085] refer to Fig. 9 In other embodiments, the in-hole introduction device 100 may include an operating handle 110, an inserting portion 6, a connector 7, a matching device 8, and a cable 9. The operating handle 110 may include a button seat 1, a first holding portion 2, a supporting portion 3, a second holding portion 4, and a locking portion 5.

[0086] Exemplarily, the insertion portion 6 includes a flexible tube 61 and a curved portion 62. The proximal end of the flexible tube 61 can be locked to the second holding portion 4 through the locking portion 5, and the distal end of the flexible tube 61 is connected to the curved portion 62. The curved portion 62 can be controlled by the first holding portion 2 to bend in different directions.

[0087] Exemplarily, the supporting device 8 includes a light source 81, a processor 82 and a display 83. The light source 81 can emit light and can transmit light to the distal end of the insertion portion 6 through the connector 7 and the cable 9. The insertion portion 6 can obtain an image using a lens (not shown). Exemplarily, the intra-hole introduction device 100 includes an image sensor that can generate an electrical signal. The processor 82 can receive an electrical signal carrying image information through the connector 7. The processor 82 is electrically connected to the display 83, and can cause the display 83 to display an image. The processor 82 can also be electrically connected to the light source 81 to control the light source 81.

[0088] The intra-hole introduction device 100 provided in the embodiment of the present disclosure can be used as an endoscope. After a user uses it for a long time, the operator's hand holding the first gripping part 2 can have a more comfortable experience, thereby ensuring the stability and reliability of the endoscopic operation.

[0089] In other embodiments, the hole introduction device 100 may include some instruments for performing actions, which may be at least partially extended to the far side of the second holding portion 4 through the locking portion 5 and controlled by the first button 201 to perform actions such as grasping, expanding, bending, and injecting liquid in the hole. By configuring the third surface area 14 of the button base 1, the first button 201 can be easily pressed to reliably and stably perform the aforementioned operations, such as the injection operation.
