Description

Instrument handle and medical instrument

Technical Field

The invention relates to the technical field of medical equipment, in particular to an instrument handle and a medical instrument.

Background

Medical device handles typically include a handle body and a sliding sleeve that is slidable thereon. The handle body is usually connected with an outer protective sheath of the medical instrument, the sliding sleeve is usually connected with an operation wire positioned in the outer protective sheath, an operator drives the operation wire to move forwards/backwards by pushing and pulling the sliding sleeve forwards/backwards, and the function of the instrument (such as the extension/retraction of the end part of the operation wire) is realized by utilizing the change of the relative positions of the outer protective sheath and the operation wire.

With the development of medical instruments, single-function medical instruments cannot meet the demands of people, and a 'two-in-one' instrument which realizes the functions of two instruments by using a single instrument is generated. However, the existing medical instrument handle is generally provided with two sliding sleeves, and two operation lines can be controlled respectively, so that the purpose of realizing the function of double instruments by a single instrument is achieved. However, such medical device handles are too long, and the two sliding sleeves may interfere with each other during use.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the invention by way of example only and that the invention may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the invention.

According to one aspect of the present invention, an instrument handle is provided. The two instruments can be independently operated through one operation piece on the instrument handle, so that each instrument can independently complete treatment and/or diagnosis tasks. According to another aspect of the present invention, there is also provided a medical device employing the device handle. As shown in fig. 1-2, the medical device includes a device handle 10 and a device portion. The instrument portion may include a first instrument and a second instrument. The first and second instruments may be connected to the instrument handle 10 by a connection (e.g., a manipulation wire) that is provided through the outer protective sheath 20 such that the first and second instruments may be extendable/retractable in an axial direction within the outer protective sheath 20. The proximal end of the outer protective sheath 20 is connected to the handle body 300 of the instrument handle 10. The instrument handle 10 will be described in detail below with reference to the accompanying drawings.

As shown in fig. 3, the instrument handle 10 may include a handle body 300, a first slider 100, a second slider 200, and an operating member 400. The handle body 300 may be generally hollow rod-shaped. In other embodiments not shown, the handle body 300 may have any other suitable shape. The proximal end of the handle body 300 may have a ring-shaped configuration to facilitate handling by an operator. The handle body 300 will serve as a fixed portion of the instrument handle 10. In general, the distal end of the handle body 300 may be used to attach the outer protective sheath 20. The distal end refers to the end of the user that is remote from the user when using the instrument handle.

The first slider 100 and the second slider 200 may be provided on the handle body 300. The first slider 100 and the second slider 200 may be slidable independently of each other in the axial direction X-X. The first slider 100 does not affect the sliding of the second slider 200 relative to the handle body 300, nor does the second slider 200 affect the sliding of the first slider 100 relative to the handle body. In the illustrated embodiment, the first slider 100 and the second slider 200 may be substantially sheet-shaped. In other embodiments not shown, the first slider 100 and the second slider 200 may also have any other suitable shape. The first slider 100 and the second slider 200 may have the same structure or may have different structures. As shown in fig. 3, the handle body 300 has a hollow cavity therein, and the first slider 100 and the second slider 200 may be accommodated in the cavity of the handle body 300.

In the embodiment shown in fig. 3, the handle body 300 is provided with a positioning hole 330. As shown in fig. 5 to 6, the first slider 100 and the second slider 200 are provided with a first hole groove 140 and a second hole groove 240, respectively, extending in the axial direction. The positioning pin 600 passes through the first and second hole slots 140 and 240, and the end is fixed in the positioning hole 330. When the first slider 100 and the second slider 200 slide in the axial direction, the positioning pin 600 may slide along the first hole groove 140 and the second hole groove 240, whereby the first slider 100 and the second slider 200 are slidably coupled with the handle body 300 by the positioning pin 600 and play a guiding role in the sliding of the first slider 100 and the second slider 200. As will be mentioned later, the operation member 400 is also to be inserted into the first and second hole grooves 140 and 240 and slid along the first and second hole grooves 140 and 240, whereby the first and second sliders 100 and 200 can be positioned at two points by the operation member 400 and the positioning pin 600, thereby ensuring the accuracy of the sliding of the first and second sliders 100 and 200 in the axial direction X-X.

The first slider 100 may be used to connect a first instrument and the second slider 200 may be used to connect a second instrument. The user can extend/retract only the first instrument by pushing and pulling the first slider 100, and can extend/retract only the second instrument by pushing and pulling the second slider 200. The first instrument and the second instrument may be selected from the same or different various forms of medical instruments as desired. Currently, there is an increasing demand for endoscopic surgery, and the main instruments used include high-frequency mucous membrane incision, and in addition to the high-frequency mucous membrane incision, other types of instruments, such as injection needles, are sometimes used in the surgery. In this case, the first instrument and the second instrument may be an incision knife and an injection needle, respectively. The two-in-one surgical instrument can reduce the cost and save the time for replacing the instrument in the operation. An operating wire connected to the first instrument may be connected to the distal end of the first slider 100. The distal end of the first slider 100 may be further provided with a first interface 150, the first interface 150 being for letting out the operation wire of the first instrument or connecting the operation wire of the first instrument to an external device. The handle body 300 may be provided with a first opening (not shown in the figures for angular reasons) through which the first interface 150 passes, the first opening having a sufficient length in the axial direction X-X to allow the first interface 150 to slide inside. Based on this, the first opening and the first interface 150 may also have a certain guiding effect. Of course, the width of the first opening may also be significantly greater than the width of the first interface 150 without guiding the first interface 150. An operating wire connected to the second instrument may be connected to the distal end of the second slider 200. The distal end of the second slider 200 may also be provided with a second interface 250, the second interface 250 being for letting out or connecting the operating wire of the second instrument to an external device. The handle body 300 may be provided with a second opening 301 through which the second port 250 is passed, the second opening 301 having a sufficient length in the axial direction X-X to allow the second port 250 to slide therein. Based on this, the second opening 301 and the second interface 250 may also have a certain guiding effect. Of course, the width of the second opening 301 may also be significantly greater than the width of the second interface 250 without guiding the second interface 250.

The operating member 400 is movable in both an axial direction X-X and a lateral direction Y-Y that is perpendicular to the axial direction X-X as seen in FIG. 3. In the illustrated embodiment, the operating member 400 is generally rod-shaped. In other embodiments not shown, the manipulator 400 may have any other suitable shape. The operating member 400 may be provided on the handle body 300. The operating member 400 can have a first clamping position and a second clamping position during movement in the lateral direction Y-Y. The first slider 100 may be provided with a first clamping portion 110, and the second slider 200 may be provided with a second clamping portion 210. The operation member 400 may be provided with a catching adapter 410. The locking adapting portion 410 may be locked with only the first locking portion 110 when the operation member 400 is at the first locking position, so as to drive the first instrument to move along the axial direction X-X. The locking adapting portion 410 is not locked with the second locking portion 210 when the operation member 400 is at the first locking position. The locking adapting portion 410 may be locked with only the second locking portion 210 when the operating member 400 is at the second locking position, so as to drive the second instrument to move along the axial direction X-X. The locking adapting portion 410 may not be locked with the first locking portion 110 when the operation member 400 is at the second locking position.

When the clamping adapting portion 410 is clamped with the first clamping portion 110, the operation member 400 can drive the first slider 100 to move along the axial direction X-X, and further drive the first instrument to move along the axial direction X-X. The operation member 400 may be located at the second holding position, similar to the operation member 400 being located at the first holding position, which will not be described herein. The clamping of the first clamping portion 110, the second clamping portion 210, and the clamping adapter portion 410 may have various forms. Typically, the first and second clamping portions 110 and 210 may take the form of blind holes, through holes, etc., and the clamping adapter 410 may take the form of pins, keys, or various other protrusions, so long as they can cooperate with the first and second clamping portions 110 and 210 so that they can be fixed in relative positions with the clamping adapter 410 along the axial direction X-X, respectively.

In the instrument handle provided by the application, the handle main body 300 is provided with the first sliding block 100 and the second sliding block 200, the operation piece 400 is provided with the first clamping position and the second clamping position respectively clamped with the first sliding block 100 and the second sliding block 200 by moving along the lateral direction Y-Y, and after the operation piece 400 is clamped with the expected sliding block, the operation piece 400 can move along the axial direction X-X together with the sliding block, so that the extension/recovery of the instrument connected with the sliding block is realized. It can be seen that the instrument handle can independently control the first slider 100 and the second slider 200 to move along the axial direction X-X by one operation member 400, and thus can independently control the first instrument connected to the first slider 100 or the second instrument connected to the second slider 200, thereby realizing the effect that one instrument handle can independently control two medical instruments respectively. And the whole structure is simple, the occupied space is small, the misoperation is not easy to happen when an operator uses the device, the work of the first instrument and the second instrument can not interfere with each other, and the whole device is safer.

For example, as shown in fig. 3 to 4, the first and second catching parts 110 and 210 may be through holes adapted to the catching adaptation part 410. The form of the clamping adapter 410 may be more varied by adopting the first and second clamping parts 110 and 210 in the form of through holes, for example, the clamping adapter 410 may include various structures such as a sphere, a cylinder, or a cone. The first and second clamping portions 110, 210 in the form of through holes also provide convenience for the structural sizing of the clamping adapter 410.

The first and second catching adaptation parts 411 and 412 may be convexly provided with respect to the body of the operation member 400. When the first and second catching portions 110 and 210 are first and second through holes penetrating the first and second sliders 100 and 200 in the lateral direction, respectively, the operating member 400 may penetrate the first and second sliders 100 and 200 in the lateral direction Y-Y. As shown in fig. 3, the first hole groove 140 communicates with the first through hole, and the width of the first hole groove 140 is smaller than the aperture of the first through hole and is adapted to the size of the main body (e.g., the small diameter portion) of the operation member 400. The second hole groove 240 communicates with the second through hole, and the width of the second hole groove 240 is smaller than the aperture of the second through hole and is adapted to the size of the main body of the operation member 400. Fig. 3 shows a case where the number of the catching adaptation parts 410 is two, and fig. 7 shows a case where the number of the catching adaptation parts 410 is one. Whether the number of snap-fit features 410 is several, it is similar to the mating of the first aperture slot 140 and the second aperture slot 240. For ease of understanding, the principle thereof will be described below with reference to fig. 7. In the state shown in fig. 7, the locking adapting portion 410 is not engaged with both the first locking portion 110 and the second locking portion 210, and the operation member 400 is at the neutral position. Typically, the neutral position is located between the first and second clamping positions. When the operation member 400 moves leftwards, the locking adapting portion 410 is engaged with the first locking portion 110, and the main body of the operation member 400, which is not provided with the locking adapting portion 410, may be disposed in the second slider 200. When the operating member 400 drives the first slider 100 to slide, the main body of the operating member 400 can slide along the second hole 240 on the second slider 200, referring to fig. 3 in combination, and thus the second slider 200 is not driven to slide along the axial direction. Similarly, when the operation member 400 moves rightward, the locking adapting portion 410 is engaged with the second locking portion 210, and the main body of the operation member 400 may be disposed through the first slider 100. When the operating member 400 drives the second slider 200 to slide, the main body of the operating member 400 can slide along the second hole 240 on the first slider 100, so as not to drive the first slider 100 to slide along the axial direction. Typically, the manipulator 400 is movable back and forth between a first clamping position and a second clamping position, and the clamping adapter 410 is movable back and forth between the first slider 100 and the second slider 200. In the case where the holding adapting portion 410 is one, the holding adapting portion 410 may be located between the first slider 100 and the second slider 200 when not held with any slider. Based on this, it may be necessary to leave a sufficient space between the first slider 100 and the second slider 200 to accommodate the chucking adaptation portion 410, and to allow the chucking adaptation portion 410 to be movable between a position chucking with the first chucking portion 110, a position chucking with the second chucking portion 210, and a neutral position not chucking with any chucking portion. If the neutral position is not required, no gap may be provided between the first slider 100 and the second slider 200, and the first slider 100 and the second slider 200 can be substantially attached to each other. This can reduce the volume of the handle body 300.

Illustratively, the first clamping portion 110 and the second clamping portion 210 may be a first blind hole and a second blind hole, respectively, as shown in fig. 8, the opening directions of the first blind hole and the second blind hole are both facing in the lateral direction and opposite to each other. In this case, the operation member 400 may not penetrate the first slider 100 and the second slider 200 in the lateral direction Y-Y. The operating member 400 may be movable between the first and second sliders 100, 200, e.g., between a first clamping position and a second clamping position. Illustratively, the operating member 400 includes a gear lever 440. The handle body 300 is provided with a knob chute 340, and the knob 440 passes out of the handle body 300 through the knob chute 340 in a direction perpendicular to the axial direction and the lateral direction Y-Y. In the resting orientation shown in fig. 3, the knob chute 340 may be disposed on top of the handle body 300. The knob 440 may be threaded upwardly out of the handle body 300. The snap fit portion 410 is connected to a gear lever 440. The number of the catching adaptation parts 410 is one. As shown in fig. 8, the locking adapting portion 410 is engaged with the first locking portion 110, and is not engaged with the second locking portion 210. When the operating member 400 moves the first slider 100 to slide, the second slider 200 does not slide along the operating member 400 in the axial direction. Similarly, when the operation member 400 moves rightward until the catching adaptation part 410 is caught with the second catching part 210, the first slider 100 does not slide along the axial direction along with the operation member 400. By providing such a knob 440, the lateral length of the operating member 400 may be shortened, but a certain clearance may be required between the first slider 100 and the second slider 200. This may result in a slightly larger volume of the handle body 300, but the operating member 400 does not protrude in a lateral direction beyond the handle body 300. In the case where the first clamping portion 110 and the second clamping portion 210 may be the first blind hole and the second blind hole, respectively, the number of the clamping adapting portions 410 may be two. The configuration of the operating member 400 can be selected as desired by those skilled in the art.

Illustratively, referring back to the embodiment shown in fig. 3-6, the snap fit features 410 may be two. As best seen in fig. 4, the latching adapter 410 may include a first latching adapter 411 and a second latching adapter 412. The first clamping adapter 411 may be clamped with the first clamping portion 110 when the operating member 400 is at the first clamping position. The second clamping adapting portion 412 is not clamped with the second clamping portion 210. The second clamping adapter 412 may be located outside the second slider 200 as shown. In this way, the space between the first slider 100 and the second slider 200 can be made small, as long as the space is capable of generating no friction when the first slider 100 and the second slider 200 slide compared to each other. Of course, in other embodiments not shown, the second clamping adapter 412 may also be located between the first slider 100 and the second slider 200. In this way, the lateral length of the operating member 400 can be shortened, but a sufficient gap needs to be left between the first slider 100 and the second slider 200. One skilled in the art can select any of the above configurations as desired. When the operation member 400 is at the second clamping position, the second clamping adapting portion 412 may be clamped with the second clamping portion 210. The first clamping adapter 411 is not clamped with the second clamping part 210. The second latching adapter 412 may be located outside the first slider 100 or between the first slider 100 and the second slider 200. In the embodiment shown in fig. 4, the manipulator 400 may also have a neutral position. The first and second latching adapter parts 411 and 412 are located at both sides of the first and second sliders 100 and 200, respectively, when the operating member 400 is in the neutral position. Of course, if the distance between the first slider 100 and the second slider 200 is sufficiently large, at least one of the first catch fitting portion 411 and the second catch fitting portion 412 may be located between the first slider 100 and the second slider 200 when the operation member 400 is in the neutral position.

The first and second catching adaptation parts 411 and 412 may be convexly provided with respect to the body of the operation member 400. Illustratively, the body of the manipulator 400 may include a shaft 413, and the shaft 413 may be parallel to the lateral direction Y-Y. The first and second catching adaptations 411 and 412 may be convexly provided on the shaft 413 in a radial direction of the shaft 413 and may be spaced apart from each other along the shaft 413. The first and second catching adaptation parts 411 and 412 may protrude in different radial directions or the same radial direction of the shaft 413. In this case, the first and second catching adaptation parts 411 and 412 may be protrusions protruding from the outer sidewall of the shaft 413 in the radial direction. Preferably, the first and second seizing fittings 411, 412 surround the entire shaft 413 in the circumferential direction of the shaft 413, for example, in a columnar shape around the shaft 413. In this way, even if the shaft 413 rotates during the movement in the lateral direction y—y, the engagement of the first and second latching fitting portions 411 and 412 with the first and second latching portions 110 and 210, respectively, can be ensured.

When moving to the first clamping position, the end surface of the clamping adapting portion 410, which is closest to the first clamping portion 110 first, is tapered gradually shrinking toward the first clamping portion 110. When moving to the second clamping position, the end surface of the clamping adapting portion 410, which is closest to the second clamping portion 210 first, is tapered gradually shrinking toward the second clamping portion 210. As shown in fig. 7, the catching adapter 410 has a first end face 410a and a second end face 410b opposite along the lateral direction Y-Y. The first end surface 410a is first adjacent to the first clamping portion 110 when the clamping adapting portion 410 moves leftwards to the first clamping position, and the first end surface 410a may have a tapered shape gradually shrinking leftwards. The second end surface 410b is first adjacent to the second clamping portion 210 when the clamping adapting portion 410 moves to the right to the second clamping position, and the second end surface 410b may be tapered to gradually shrink to the right. By providing such tapered end surfaces, when the clamping adapting portion 410 moves to the first clamping position and the second clamping position, the two end surfaces can respectively play a guiding role, so that the clamping adapting portion 410 can be smoothly clamped with the first clamping portion 110 and the second clamping portion 210, and the hand feeling of an operator is better.

In the case where the latching adaptation part 410 includes the first latching adaptation part 411 and the second latching adaptation part 412, as shown in fig. 4, both the first latching adaptation part 411 and the second latching adaptation part 412 move toward the middle of the first slider 100 and the second slider 200 when they are to be engaged with the first latching part 110 and the second latching part 210, respectively. The inner side 411a of the first clamping adapter 411 facing the second clamping adapter 412 is tapered gradually shrinking toward the second clamping adapter 412. In this way, the first clamping adapting portion 411 can play a guiding role when moving to be clamped with the first clamping portion 110, so that the hand feeling of an operator is smoother. Illustratively, an inner side surface 412a of the second latching adaptation portion 412 facing the first latching adaptation portion 411 is tapered gradually shrinking toward the first latching adaptation portion 411. In this way, the second clamping adapting portion 412 can play a guiding role when moving to be clamped with the second clamping portion 210, so that the hand feeling of an operator is smoother.

If the first and second latching adaptation parts 411 and 412 are to be engaged with the first and second latching parts 110 and 210, respectively, they are not moved toward the middle of the first and second sliders 100 and 200 as in fig. 4, but are moved from the middle of the first and second sliders 100 and 200 toward the outer sides of the first and second sliders 100 and 200, respectively. In this case, the outer side of the first latching fitting part 411 facing away from the second latching fitting part 412 and the outer side of the second latching fitting part 412 facing away from the first latching fitting part 411 are tapered.

Taking an example in which the manipulator 400 shown in fig. 4 includes the shaft 413, a portion of the shaft 413 outside the first and second holding-fit portions 411 and 412 has a diameter D1, a portion of the shaft 413 between the first and second holding-fit portions 411 and 412 has a diameter D3, and the first and second holding-fit portions 411 and 412 may be symmetrically disposed about a center of the shaft 413. The inner sides of the first and second catching adaptation parts 411 and 412 opposite to each other are tapered. The diameter at the maximum cross section of the first and second seizing adaptation parts 411 and 412 is D2. D2 is greater than D1, and D2 is greater than D3. D1 and D3 may be equal or unequal. The first and second latching parts 110 and 210 are in the form of through holes that match the first and second latching adaptation parts 411 and 412, respectively. The diameter of the through hole may be slightly larger than D2. When the operating member 400 is located at the first clamping position as shown in the drawing, the first clamping adapting portion 411 and the first clamping portion 110 form a clamping connection, and the operating member 400 can drive the first slider 100 to slide relative to the handle body 300 in the axial direction X-X, at this time, the second clamping adapting portion 412 is located outside the second slider 200, so that the second slider 200 is not affected by the sliding of the operating member 400. When the second slider 200 needs to be manipulated, the operation member 400 may drive the first slider 100 to return to the initial position. Then, the operation member 400 moves to the second clamping position in the lateral direction Y-Y, so that the second clamping adapting portion 412 and the second clamping portion 210 form a clamping, and the operation member 400 can drive the second slider 200 to slide relative to the handle body 300 in the axial direction X-X, at this time, the first clamping adapting portion 411 is located on the outer side of the first slider 100, and therefore the first slider 100 is not affected by the sliding of the operation member 400. By providing two holding adapting portions, i.e., the first holding adapting portion 411 and the second holding adapting portion 412, they can be made to be held with the first holding portion 110 and the second holding portion 210 from the outside of the first slider 100 and the second slider 200, respectively. In this way, it is unnecessary to leave a large gap between the first slider 100 and the second slider 200 to accommodate the first catch fitting 411 and the second catch fitting 412, so that space within the handle body 300 can be saved.

In the above embodiment, the shaft 413 penetrates the first slider 100 and the second slider 200 to be caught with them from opposite inner sides or opposite outer sides of the first slider 100 and the second slider 200. In other embodiments not shown, the first and second clamping portions 110 and 210 may be grooves provided on the top or bottom (in the placement position shown in fig. 3) of the first and second sliders 100 and 200, respectively, in which case, the shaft 413 may be provided with a protrusion protruding only toward the groove, and the protrusion may be capable of driving the first slider 100 to move in the axial direction X-X when being slid to engage with the groove on the first slider 100, and driving the second slider 200 to move in the axial direction X-X when being slid to engage with the groove on the second slider 200.

As illustrated in fig. 3 to 4, first and second grooves 310 and 320 may be provided on opposite sidewalls of the handle body 300 in the lateral direction Y-Y, respectively. The first slider 100 and the second slider 200 are slidably disposed between the two sidewalls. The first slot 310 may be adjacent to the first slider 100. The sidewall where the first slot 310 is located may be located outside the first slider 100. The second slot 320 may be adjacent to the second slider 200. The sidewall where the second slot 320 is located may be located outside the second slider 200. The first slot 310 may include a first shuttle opening 311 for the first latching adapter 411 to shuttle in the lateral direction Y-Y. Illustratively, the first shuttle port 311 may be circular in shape matching the first snap fit 411 and have a diameter D2. In other embodiments, the first shuttle opening 311 may have other shapes as long as the first clamping adapter 411 can be shuttled back and forth in the lateral direction. The first slot 310 may also include a first runner 312 extending distally in the axial direction X-X from the first shuttle port 311. The operating member 400 is slidable on the first slide slot 312. The second slot 320 may include a second shuttle port 321 for shuttling the second snap fit portion 412 in the lateral direction Y-Y. Illustratively, the second shuttle port 321 may be circular in shape matching the second snap fit 412 and have a diameter D2. In other embodiments, the second shuttle opening 321 may have other shapes as long as the second clamping adapter 412 can be shuttled back and forth in the lateral direction. The second slot 320 may also include a second runner 322 extending distally in the axial direction X-X from the second shuttle port 321. The operating member 400 is slidable on the second chute 322. The dimensions of both the first runner 312 and the second runner 322 may be matched to the dimensions of the body (e.g., shaft 413) of the operator 400. Illustratively, the widths of the first and second sliding grooves 312, 322 may be slightly greater than D1, such that only the body (e.g., shaft 413) of the operating member 400 may slide over the first and second sliding grooves 312, 322, and the first and second snap fit portions 411, 412 may not enter into the first and second sliding grooves 312, 322. The movement of the first slider 100 and the second slider 200 in the axial direction X-X can be guided by the sliding of the body (e.g., the shaft 413) of the operation member 400 within the first chute 312 and the second chute 322. Moreover, since the main body of the operation member 400 can slide in the first sliding groove 312 and the second sliding groove 322, when the operation member 400 is clamped with the first sliding block 100 and drives the first sliding block 100 to slide, the main body of the operation member 400 can slide in the second sliding groove 322, and the second sliding block 200 is not driven to slide. Vice versa, when the operating member 400 is clamped with the second slider 200 and the second slider 200 slides, the main body of the operating member 400 can slide in the first sliding slot 312, and the first slider 100 is not driven to slide.

1-3, the instrument handle may further include a sliding sleeve 500, the sliding sleeve 500 may be slidably sleeved on the handle body 300 along the axial direction X-X, and the operating member 400 may be movably sleeved on the sliding sleeve 500 along the lateral direction Y-Y. The operation member 400 can be driven to slide by the operation sliding sleeve 500, so that the operation member 400 can slide more stably. Moreover, the sliding sleeve 500 can protect the internal structure of the instrument handle, and can especially wrap the first clamping portion 110, the second clamping portion 210 and the clamping adapting portion 410, so that the clamping fit is more stable.

Illustratively, a first button 420 may be connected to an end of the operating member 400 adjacent to the first catching adaptation part 411, and the first button 420 may be located outside the sliding sleeve 500. When the operation member 400 is in the first holding position, the first button 420 may abut against the outer surface of the sliding sleeve 500 along the lateral direction Y-Y, as shown in fig. 4, and the first holding adapting portion 411 abuts against the inner surface of the sidewall where the first sliding slot 312 is located along the lateral direction Y-Y. In this way, when the operating member 400 drives the first slider 100 to move along the axial direction X-X, the first button 420 and the first clamping adapter 411 can be clamped between the inside of the handle body 300 and the outside of the sliding sleeve 500, so that the operating member 400 drives the first slider 100 to slide smoothly along the axial direction X-X. Illustratively, a second button 430 may be attached to an end of the operating member 400 adjacent to the second snap fit portion 412, and the second button 430 may be located outside of the sliding sleeve 500. The second button 430 can rest against the outer surface of the sliding sleeve 500 in the lateral direction Y-Y when the operating member 400 is in the second retaining position. The second clamping adapter 412 abuts against the inner surface of the sidewall of the second chute 322 along the lateral direction Y-Y. In this way, when the operating member 400 moves the second slider 200 in the axial direction X-X, the second button 430 and the second latching adapter 412 can be clamped between the inside of the handle body 300 and the outside of the sliding sleeve 500, so that the operating member 400 moves the second slider 200 to be smoothly slid in the axial direction X-X.

The instrument handle 10 may also include a locking mechanism movable between a locked position in engagement with the locking portion and an unlocked position out of engagement with the locking portion. The locking mechanisms are arranged in one-to-one correspondence with the first sliding blocks and/or the second sliding blocks. That is, only the first slider may have a corresponding locking mechanism, only the second slider may have a corresponding locking mechanism, or both the first slider and the second slider may have a corresponding locking mechanism. For each locking mechanism, when the locking adapting portion 410 of the operating member 400 is engaged with one slider (for example, the slider a may be a first slider or a second slider) corresponding to the locking mechanism, the locking mechanism moves to the unlocking position to unlock the slider a; and when the latching adapter 410 is snapped with another slider, the locking mechanism moves to the locking position to lock the slider a. Thus, when sliding of the slider a is desired, the locking mechanism corresponding to the slider a is in the unlocking position to release the slider a, and when sliding of the slider B is desired, the locking mechanism corresponding to the slider a is in the locking position to lock the slider a. Thus, the slider a can be reliably fixed to the handle body 300 when the slider a is not intended to slide, preventing the slide a from being unexpectedly moved from the intended position.

In one set of embodiments, the locking mechanisms may be disposed on corresponding sliders, and the locking portions may be disposed on the handle body 300, for each locking mechanism, during the engagement of the latching adapter 410 with the corresponding slider of the locking mechanism, the latching adapter 410 cooperates with the locking mechanism to push the locking mechanism to the unlocked position. Thus, the locking mechanism of the slider desired to be moved can be triggered to be unlocked by the catching adapter 410 on the operating member 400, without a separate locking/unlocking operating member to trigger the locking mechanism, so that the operation is simpler and erroneous operation is less likely to occur. Of course, the present invention does not exclude the case of triggering the locking mechanism by a separate locking/unlocking operation member. The separate locking/unlocking operation member may be a knob, a button, a handle or a paddle, etc.

As shown in fig. 4-6, for example, the first slider 100 may be provided with a first locking mechanism, such as a first locking pawl 120, movable between a first locking position and a first unlocking position, the first locking pawl 120 being retractable to the first unlocking position when the operating member 400 is in the first holding position, and the first locking pawl 120 being extendable to the first locking position when the operating member 400 is in the second holding position. As shown in fig. 4-6, the first locking pawl 120 is now in the first unlocked position. The second locking claw 220 on the second slider 200, which will be described later, is in its second locking position. The first locking claw 120 may have various shapes such as a V-shape, an L-shape, or a semicircular shape, which are not particularly limited herein.

The handle body 300 may be provided with a first locking portion which may be used to lock with the first locking pawl 120 in the first locking position. The first locking portion may be an opening, a groove, a protrusion, or the like provided on the handle body 300 as long as the first locking claw 120 in the first locking position can be blocked from moving in the axial direction X-X. When the operating member 400 is in the second holding position, the first locking pawl 120 is in the first locking position in which the first locking portion will lock with the first locking pawl 120, and the first locking portion can restrict movement of the first locking pawl 120 and thus the first slider 100. When the operation member 400 is at the first holding position, the first locking claw 120 is at the first unlocking position, and the first locking portion is not locked with the first locking claw 120, that is, the first locking portion does not limit the movement of the first slider 100. The first locking portion may include various structures, and the locking of the first locking portion with the first locking claw 120 may be in various forms such as a snap fit, an interference fit, or a magnetic attraction fit.

Although in the embodiment shown in fig. 4 the first slider 100 is located on the left side and the second slider 200 is located on the right side, in other embodiments not shown the positions of the first slider 100 and the second slider 200 may be interchanged.

Illustratively, the first locking pawl 120 may be located on a side of the first slider 100 opposite the second slider 200. During the movement of the operation member 400 to the first latching position, the inner side surface of the first latching adapting portion 411 (i.e., the side surface facing the second latching adapting portion 412) may cooperate with the first locking pawl 120 to push the first locking pawl 120 to the first unlocking position. The first locking claw 120 is located at a side of the first slider 100 facing away from the second slider 200, and when the inner side of the first clamping adapting portion 411 is tapered, the first clamping adapting portion 411 can continuously and stably push the first locking claw 120, and the first locking claw 120 cannot be suddenly pushed by a large angle, so that the stability of the whole device is enhanced.

Illustratively, the first locking pawl 120 may be pivotally connected to the first slider 100 about a pivot axis. The first locking claw 120 may have a V-shape, and the pivot may be located at a bent portion of the V-shape. The catch adapter 410 may cooperate with one end of the V-shape for retraction to the first unlocked position, the other end of the V-shape for locking with the first locking portion. Illustratively, during movement of the operating member 400 to the first retaining position, the first retaining adapter 411 may push the first locking pawl 120 upward (based on the rest position of fig. 3-5), thereby allowing the first locking pawl 120 to move to the first unlocking position. The use of the V-shaped first locking pawl 120 provides even more space savings in the handle body 300. The pivotable connection of the first locking jaw 120 to the first slider 100 may reduce the space occupied by the first locking jaw 120, thereby avoiding an excessive size of the handle body 300. In other embodiments, not shown, the first locking pawl 120 is also translatable between the first unlocked position and the first locked position. Moving the first locking pawl 120 in a translational manner may simplify the structure of the locking mechanism. Illustratively, the first locking pawl 120 is provided with a first angled surface that faces away from the first slider 100. In fig. 3, the first slope faces the first button 420. The inner side 411a of the first latching adapter 411 facing the first slider 100 engages with the first inclined surface to push the first locking pawl 120 to the unlocked position. The first ramp may translate translation of the first catch adapter 411 in the lateral direction Y-Y into rotation of the first locking pawl 120, whereby the first ramp may facilitate such translation between directions of movement.

For example, a first elastic member 130 may be provided on the first slider 100, and the first elastic member 130 applies an elastic force to the first locking pawl 120 toward the locking position. The first elastic member 130 may be disposed between the first locking pawl 120 and the first slider 100. The first elastic member 130 applies an elastic force to the first locking pawl 120 toward the first locking position. The first elastic member 130 may be a spring or an elastic body made of an elastic material, etc. In this case, the first elastic member 130 may be clamped between the top of the first locking claw 120 and the first slider 100. The first elastic member 130 may allow the first locking position to be a normal position of the first locking jaw 120, thereby ensuring that the first slider 100 can be reliably positioned at a desired position. Illustratively, the first elastic member 130 may be cantilevered and integral with the first slider 100. Therefore, the number of parts can be reduced, and the assembly difficulty is reduced.

In other embodiments not shown, the first resilient member 130 may comprise a torsion spring that is journaled with one end against the first locking pawl 120 and the other end against the first slider 100. In this way, standard components can be selected, which is beneficial to cost reduction.

Illustratively, the second slider 200 may be provided with a second locking mechanism, such as a second locking pawl 220, movable between a second locking position and a second unlocking position, the second locking pawl 220 being retractable to the second unlocking position when the operating member 400 is in the second retaining position, and the second locking pawl 220 being extendable to the second locking position when the operating member 400 is in the first retaining position. As shown in fig. 4-6, the second locking pawl 220 is now in the second locking position. The second locking claw 220 may have various shapes such as a V-shape, an L-shape, or a semicircular shape, and is not particularly limited herein.

The handle body 300 may be provided with a second locking portion which may be used to lock with the second locking claw 220 in the second locking position. The second locking portion may be an opening, a groove, a protrusion, or the like provided on the handle body 300 as long as the second locking claw 220 in the second locking position can be blocked from moving in the axial direction X-X. When the operating member 400 is in the first holding position, the second locking pawl 220 is in the second locking position, and the second locking portion will lock with the second locking pawl 220, the second locking portion can restrict movement of the second locking pawl 220 and thus the second slider 200. When the operation member 400 is at the second holding position, the second locking claw 220 is at the second unlocking position, and the second locking portion is not locked with the second locking claw 220, that is, the second locking portion is not limited to move of the second slider 200. The second locking portion may include various structures, and the locking of the second locking portion with the second locking claw 220 may be in various forms such as a snap fit, an interference fit, or a magnetic attraction fit.

Illustratively, the second locking pawl 220 may be located on a side of the second slider 200 facing away from the first slider 100, wherein an inner side of the second latching adapter 412 (i.e., a side facing the first latching adapter 411) may cooperate with the second locking pawl 220 to urge the second locking pawl 220 to the second unlocked position during movement of the operating member 400 to the second latching position. The second locking claw 220 is located at a side of the second slider 200 opposite to the first slider 100, and when the inner side of the second clamping adapting portion 412 is tapered, the second clamping adapting portion 412 can continuously and stably push the second locking claw 220, and the second locking claw 220 cannot be suddenly pushed to a large angle, so that the stability of the whole device is enhanced.

Illustratively, the second locking pawl 220 can be pivotally connected to the second slider 200 about a pivot 222 as shown in FIG. 3. The second locking claw 220 may have a V-shape, and the pivot 222 may be located at a bend of the V-shape. The second latching adapter 412 may be mated with one end of the V-shape for retraction to the second unlocked position, and the other end of the V-shape may be used for locking with the second locking portion. Illustratively, during movement of the operating member 400 to the second retaining position, the second retaining adapter 412 may push the second locking pawl 220 upward (based on the rest position of fig. 3-5), thereby allowing the second locking pawl 220 to move to the second unlocking position. The use of the V-shaped second locking pawl 220 saves more space within the handle body 300. The pivotal connection of the second locking claw 220 to the second slider 200 may reduce the space occupied by the second locking claw 220, thereby avoiding the handle body 300 from being excessively large. In other embodiments not shown, the second locking pawl 220 is also translatable between the second unlocked position and the second locked position. Moving the second locking pawl 220 in a translational manner may simplify the structure of the locking mechanism. Illustratively, the second locking pawl 220 is provided with a second angled surface 220a, the second angled surface 220a facing away from the second slider 200. In fig. 3, the second inclined surface 220a faces the second button 430. The inner side surface 412a of the second latching adapting portion 412 facing the second slider 200 is engaged with the second inclined surface 220a to push the second locking claw 220 to the unlocking position. The second ramp 220a may translate the translation of the second snap fit 412 in the lateral direction Y-Y into rotation of the second locking pawl 220, whereby the second ramp 220a may facilitate such translation between directions of movement.

Illustratively, a second elastic member 230 may be provided on the second slider 200, and the second elastic member 230 applies an elastic force to the second locking pawl 220 toward the locking position. The second elastic member 230 may be disposed between the second locking claw 220 and the second slider 200. The second elastic member 230 may apply an elastic force to the second locking pawl 220 toward the second locking position. The second elastic member 230 may be a spring or an elastic body made of an elastic material, etc. In this case, the second elastic member 230 may be clamped between the top of the second locking claw 220 and the second slider 200.
