Description

Technical Field

[0001] This utility model relates to the field of ultrasonic probe technology, specifically to an operating handle for a transesophageal ultrasonic probe. Background Technology

[0002] In terms of patient examinations, doctors in the medical field can currently perform both external and internal examinations. Internal examinations often utilize transesophageal ultrasound (TEU) probes. A TEU probe typically consists of an insertion section that goes into the esophagus and an operating handle that remains outside the body.

[0003] In existing technologies, operating handles that remain outside the human body are generally elongated cylindrical in shape. These handles consist of a cylindrical handle body and buttons and knobs mounted on its surface. The direction of button presses is generally perpendicular to the axial direction of the handle body; that is, the angle between the button mounting surface and the axial direction of the handle body is 0 degrees. When holding the handle body and pressing the buttons with a finger, the buttons move perpendicular to the handle body. This mismatch between the button's movement direction and the bending direction of the finger during button operation leads to inconvenience in button operation. Utility Model Content Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing transesophageal ultrasound probe's operating handle, such as the poor fit between the buttons and fingers and the inconvenience of button operation, thereby providing an operating handle for a transesophageal ultrasound probe.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An operating handle for a transesophageal ultrasound probe includes a handle housing and a button. The handle housing has a button platform protruding outward from its outer contour. The button platform has a button mounting plane, and the button is mounted on the button mounting plane. The plane where the button mounting plane is located forms an angle with the longitudinal direction of the handle housing. One side of the handle housing also has a first protrusion protruding outward. The first protrusion is adapted to press against the transverse crease of the thumb metacarpophalangeal joint or the proximal phalanx of the thumb when the operator holds the handle housing, so as to allow the operator's finger to press the button within its bending range.

[0005] Furthermore, the angle between the plane where the button mounting surface is located and the longitudinal direction of the handle housing ranges from 1° to 89°.

[0006] Furthermore, the handle housing includes a central outer shell body, a proximal interface located near the proximal end of the outer shell body, and a distal interface located far from the proximal end of the outer shell body; the proximal interface is adapted to connect a cable led out from the ultrasound host, and the distal interface is adapted to connect a cable led out from the ultrasound probe; the button and the first protrusion are both disposed on the outer shell body.

[0007] Furthermore, the outer shell body includes a proximal shell segment, an intermediate shell segment, and a distal shell segment arranged sequentially and linearly along the longitudinal direction from the proximal interface to the distal interface.

The proximal side of the first protrusion has a first inclined arc surface extending towards the proximal shell segment in an arc transition form, and the distal side of the first protrusion has a second inclined arc surface extending towards the distal shell segment in an arc transition form. The button platform is disposed on the first inclined arc surface. When the operator holds the handle shell, the second inclined arc surface fits into the palm of the operator's hand, and the first protrusion abuts against the transverse crease of the metacarpophalangeal joint of the operator's thumb or the proximal phalanx of the thumb, so as to allow the distal phalanx of the operator's thumb to press the button within the range of bending motion.

[0008] Furthermore, the intermediate housing segment is also provided with a second protrusion protruding outward, the second protrusion and the first protrusion being located on opposite sides of the intermediate housing segment, the second protrusion being closer to the proximal housing segment than the first protrusion; the proximal side of the second protrusion is provided with a third inclined arc surface extending towards the proximal housing segment in an arc transition form, and the distal side of the second protrusion is provided with a fourth inclined arc surface extending towards the distal housing segment in an arc transition form; when the operator holds the handle housing with their hand, the fourth inclined arc surface fits into the four fingers of the operator's palm excluding the thumb, and the second protrusion positions the operator's index finger.

[0009] Furthermore, both the near-end interface and the far-end interface are curved, and both the near-end interface and the far-end interface are curved in a clockwise direction or in a counterclockwise direction relative to the housing body.

[0010] Furthermore, the outer shell body includes a proximal shell segment, an intermediate shell segment, and a distal shell segment arranged sequentially from the proximal interface to the distal interface. The intermediate shell segment and the distal shell segment are arranged in a straight line along the longitudinal direction. The proximal shell segment and the intermediate shell segment are arranged at an angle. The button platform is disposed on the intermediate shell segment on the concave side of the outer shell body. The first protrusion and the button platform are respectively located on opposite sides of the intermediate shell segment.

[0011] Furthermore, the concave side of the outer shell body is also provided with a second protrusion; the distal end of the first protrusion is provided with a first inclined arc surface extending towards the distal shell segment in an arc transition form, and the distal end of the first protrusion is provided with a second inclined arc surface extending towards the distal shell segment in an arc transition form; the proximal end of the second protrusion is provided with a third inclined arc surface extending towards the proximal shell segment in an arc transition form, and the distal end of the second protrusion is provided with a fourth inclined arc surface extending towards the distal shell segment in an arc transition form; the third inclined arc surface and the fourth inclined arc surface... The inclined arc surfaces are each provided with the button platform and the button; when the operator holds the handle housing, the second inclined arc surface fits into the palm of the operator's hand, the fourth inclined arc surface fits into the little finger of the operator, the first protrusion abuts against the transverse crease of the metacarpophalangeal joint of the operator's thumb or the proximal phalanx of the thumb, the second protrusion abuts against the middle finger of the operator, so as to allow the operator's index finger to press the button on the third inclined arc surface within the range of bending activity, and to allow the operator's ring finger to press the button on the fourth inclined arc surface within the range of bending activity.

[0012] Furthermore, the distal interface is curved, and the length extension direction of the proximal interface is in the same direction as the length extension direction of the proximal housing segment.

[0013] Furthermore, the operating handle also includes a knob connected to the handle housing, and the button and the knob are disposed on different sides of the same tube segment of the handle housing.

[0014] Furthermore, both the button and the knob are disposed on the middle housing section of the handle housing. The middle housing section includes a pair of wide side surfaces and a pair of narrow side surfaces arranged opposite to each other. The first protrusion and the second protrusion are respectively located on the two narrow side surfaces. The button is disposed on one of the narrow side surfaces. The knob is connected to one of the wide side surfaces.

[0015] The present invention has the following advantages: When the operating handle of this transesophageal ultrasound probe is held, the first protrusion on the outer periphery of the handle housing can guide the operator's hand posture when holding the handle housing, which is conducive to forming a uniform holding standard where the transverse crease of the thumb metacarpophalangeal joint or the proximal phalanx of the thumb presses against the first protrusion; moreover, the plane on which the button is mounted is set at an angle to the longitudinal direction of the handle housing, so that when the operator's hand is held on the handle housing, the operator's fingers can press the button within their own bending range, making the operation of pressing the button simpler.

[0023] To address the problem of poor button fit between the buttons and fingers in the operating handle of existing transesophageal ultrasound probes, resulting in inconvenient button operation, this application provides an operating handle for a transesophageal ultrasound probe.

[0024] Example 1 like Figure 1 and Figure 2 The diagram shows an operating handle for a transesophageal ultrasound probe. The operating handle includes a handle housing 1, buttons 2, and knobs 4. Buttons 2 and knobs 4 are both located on the outer periphery of the handle housing 1, and are situated on different sides of the handle housing 1. Multiple buttons 2 are provided, and two knobs 4 are coaxially arranged. When the operator holds the handle housing 1, they can press different buttons 2 or turn different knobs 4 to perform corresponding control functions.

[0025] like Figure 1 , Figure 2 and Figure 6As shown, the handle housing 1 includes a central outer shell body 11, a proximal interface 12 located near the proximal end of the outer shell body 11, and a distal interface 13 located at the distal end of the outer shell body 11. The outer contour of the outer shell body 11 conforms to the grip posture of the operator's hand, improving the ease of gripping the handle housing 1 and reducing the risk of slipping during gripping. The knob 4 and button 2 are both located on different sides of the same section of the outer shell body 11. The proximal interface 12 is suitable for connecting the cable led out from the ultrasound host, and the distal interface 13 is suitable for connecting the cable led out from the ultrasound probe.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, both the near-end interface 12 and the far-end interface 13 are curved, and both are bent clockwise or counterclockwise relative to the main body 11. The curved design of the near-end interface 12 causes the cable connected to it to bend in the outgoing direction, creating a larger angle between the cable's outgoing direction and the operator's hand. This facilitates gripping the handle housing 1, protects the cable from excessive bending during operation, and extends its lifespan. Similarly, the curved design of the far-end interface 13 causes the cable connected to it to bend in the outgoing direction, ensuring a smooth transition and preventing excessive bending during operation.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the outer shell body 11 includes a proximal shell segment 111, an intermediate shell segment 112, and a distal shell segment 113 arranged sequentially from the proximal interface 12 to the distal interface 13. The proximal shell segment 111, the intermediate shell segment 112, and the distal shell segment 113 are arranged in a straight line along the longitudinal direction of the outer shell body 11. The intermediate shell segment 112 includes a pair of oppositely arranged wide side surfaces 112g and a pair of oppositely arranged narrow side surfaces. The lengths of the wide side surfaces 112g and the narrow side surfaces are the same, and the width of the wide side surface 112g is greater than the width of the narrow side surface. The knob 4 is connected to one of the wide side surfaces 112g. One of the narrow side surfaces of the intermediate shell segment 112 has an outwardly protruding first protrusion 112a. The proximal side of the first protrusion 112a has a first inclined arc surface 112c extending towards the proximal shell segment 111 in an arc transition form, and the distal side of the first protrusion 112a has a second inclined arc surface 112d extending towards the distal shell segment 113 in an arc transition form. The first protrusion 112a can guide and position the grip posture. When the operator holds the outer shell body 11, the first protrusion 112a can guide the operator's hand to hold the outer shell body 11 and position the grip position of the palm, which is conducive to forming a uniform grip standard where the transverse crease of the metacarpophalangeal joint of the thumb or the proximal phalanx of the thumb presses against the first protrusion 112a.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the first inclined arc surface 112c is provided with a button platform 3 protruding outward from the outer contour of the middle housing section 112. The button platform 3 is provided with a button mounting plane 301, and the button 2 is mounted on the button mounting plane 301. The plane where the button mounting plane 301 is located is set at an angle to the longitudinal direction of the handle housing 1. The angle between the plane where the button mounting plane 301 is located and the longitudinal direction of the handle housing 1 ranges from 1° to 89°. For example, in some embodiments, the angle between the plane where the button mounting plane 301 is located and the longitudinal direction of the handle housing 1 is 10°, 20°, or 30°.

[0029] like Figure 4 and Figure 6 As shown, when the operator's hand is in the posture of holding the outer shell 11, the second inclined arc surface 112d fits into the palm of the operator's hand, and the first protrusion 112a abuts against the transverse crease of the metacarpophalangeal joint of the operator's thumb or the proximal phalanx of the thumb, allowing the distal phalanx of the operator's thumb to press the button 2 on the first inclined arc surface 112c within its bending range. At the same time, it allows the operator's thumb to move the knob 4 located on the wide side 112g within its bending range. This allows the operator to select to press the button 2 or move the knob 4 by using the bending movement of the thumb when holding the outer shell 11, enabling blind operation of the handle and making operation simpler, thus solving the problem of inconvenience caused by the flatness of the buttons. Moreover, the plane where the button mounting plane 301 is located is set at an angle to the longitudinal direction of the handle shell 1. When the operator's hand is holding the handle shell 1, the operator's thumb can press the button 2 and move the knob 4 within its own bending range, making the operation of pressing the button 2 even simpler.

[0030] The transverse crease of the thumb's metacarpophalangeal joint refers to the transverse crease where the base of the thumb connects to the palm; it is the skin fold that spans the surface of the thumb's metacarpophalangeal joint. Of the two phalanges of the thumb, the one located at the base of the thumb and connecting to the metacarpal bones is the proximal phalanx, and the other phalanx farther from the palm is the distal phalanx. The joint formed by the distal phalanx and proximal phalanx is the interphalangeal joint of the thumb, and the transverse skin groove on the palmar surface of the interphalangeal joint is the transverse crease of the interphalangeal joint. The proximal phalanx of the thumb is the base portion of the thumb, including the proximal phalanx and its surrounding skin tissue; it is the segment of the finger between the transverse crease of the thumb's metacarpophalangeal joint and the transverse crease of the interphalangeal joint. The proximal phalanx of the thumb is also called the proximal phalanx of the thumb or the first phalanx of the thumb. The distal phalanx of the thumb is the tip of the thumb, including the distal phalanx and the surrounding skin tissue. It is the segment of the finger between the transverse crease of the thumb interphalangeal joint and the tip of the thumb. The distal phalanx of the thumb is also called the distal phalanx of the thumb, the distal phalanx of the thumb, or the second segment of the thumb.

[0031] like Figure 5 and Figure 6 As shown, in some embodiments, the intermediate housing segment 112 is further provided with an outwardly protruding second protrusion 112b. The second protrusion 112b and the first protrusion 112a are located on opposite sides of the intermediate housing segment 112, with the second protrusion 112b being closer to the proximal housing segment 111 than the first protrusion 112a. The proximal side of the second protrusion 112b is provided with a third inclined arc surface 112e extending towards the proximal housing segment 111 in an arc transition form, and the distal side of the second protrusion 112b is provided with a fourth inclined arc surface 112f extending towards the distal housing segment 113 in an arc transition form. When the operator holds the handle housing 1 with their hand, the fourth inclined arc surface 112f fits into the four fingers of the operator's hand, excluding the thumb, and the second protrusion 112b positions the operator's index finger. The second protrusion 112b works in conjunction with the first protrusion 112a to better position and position the operator's hand holding the outer shell 11; while the fourth inclined arc surface 112f can better match the operator's fingers, improve the grip fit, and reduce the risk of slipping during gripping.

[0032] Example 2 like Figure 7 and Figure 8The operating handle for a transesophageal ultrasound probe shown differs from that in Embodiment 1 in that the outer shell body 11 includes a proximal shell section 111, an intermediate shell section 112, and a distal shell section 113 arranged sequentially from the proximal interface 12 to the distal interface 13. The intermediate shell section 112 and the distal shell section 113 are arranged in a straight line along the longitudinal direction. The proximal shell section 111 and the intermediate shell section 112 are arranged at an angle. The button platform 3 is disposed on the intermediate shell section 112 on the concave side of the outer shell body 11. The first protrusion 112a and the button platform 3 are located on opposite sides of the intermediate shell section 112, respectively.

[0033] like Figure 7 and Figure 8 As shown, the distal end of the first protrusion 112a has a first inclined arc surface 112c extending towards the distal housing segment 113 in an arc transition form, and the distal end of the first protrusion 112a has a second inclined arc surface 112d extending towards the distal housing segment 113 in an arc transition form. The concave side of the outer shell body 11 has a second protrusion 112b, the proximal end of the second protrusion 112b has a third inclined arc surface 112e extending towards the proximal housing segment 111 in an arc transition form, and the distal end of the second protrusion 112b has a fourth inclined arc surface 112f extending towards the distal housing segment 113 in an arc transition form. There are two button platforms 3, each button platform 3 is provided with a button 2, one button platform 3 is set on the third inclined arc surface 112e, and the other button platform 3 is set on the fourth inclined arc surface 112f.

[0034] like Figure 7 and Figure 8 As shown, when the operator's palm is holding the outer casing 11, the second inclined arc surface 112d fits into the operator's palm, the fourth inclined arc surface 112f fits into the operator's little finger, the first protrusion 112a abuts against the transverse crease of the thumb's metacarpophalangeal joint or the proximal phalanx of the thumb, and the first inclined arc surface 112c fits into the bending shape of the operator's thumb. The operator's thumb can move the knob 4 within its bending range, the operator's middle finger rests on the second protrusion 112b, the operator's index finger can press the button 2 on the third inclined arc surface 112e within its bending range, and the operator's ring finger can press the button 2 on the fourth inclined arc surface 112f within its bending range. When holding the outer casing 11, the operator can use the bending movements of the thumb, index finger, and ring finger to select to press the button 2 or move the knob 4, realizing blind operation of the handle, making operation simpler and solving the problem of inconvenience caused by the flatness of the buttons.

[0035] like Figure 7 and Figure 8As shown, the length extension direction of the near-end interface 12 is in the same direction as the length extension direction of the near-end housing section 111, while the far-end interface 13 is curved. The curved design of the far-end interface 13 causes the cable connected to it to bend in the outgoing direction. This allows the cable's outgoing direction to form a large angle with the operator's hand when gripping the handle housing 1, facilitating the operator's grip and protecting the cable from excessive bending during operation, thus extending the cable's lifespan. Since the near-end housing section 111 of the main housing body 11 is already curved relative to the middle housing section 112, the near-end interface 12 is also curved relative to the middle housing section 112. This allows the cable connected to the near-end interface 12 to transition smoothly, preventing excessive bending during operation.

[0036] In summary, the operating handle for a transesophageal ultrasound probe provided in this embodiment of the invention offers advantages such as a high degree of fit between the shape of the handle housing 1 and the operator's hand posture, enhancing ease of use. The first protrusion 112a on the outer periphery of the handle housing 1 guides the operator's hand posture, facilitating a standardized grip where the thumb's metacarpophalangeal joint crease or the proximal phalanx of the thumb rests against the first protrusion 112a. Furthermore, the plane where the button mounting surface 301 is located forms an angle with the longitudinal direction of the handle housing 1. When the operator's hand grips the handle housing 1, their fingers can press the button 2 and turn the knob 4 within their own range of motion, simplifying the operation of pressing the button 2.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
