Referring to fig. 1 to 4, the medical handle 10 provided by the present utility model includes a handle body 100, a sliding grip 200, a pulling cable 300, a sleeve 400 and a rotating set 500. The handle body 100 extends longitudinally along the front-back direction, the front end of the handle body 100 is provided with a long hole 110, the long hole 110 comprises a first hole section 111 and a second hole section 112 which are communicated sequentially from front to back, and the second hole section 112 penetrates through the handle body 100 along the width direction; the sliding handle 200 includes a sliding sleeve 210 and a sliding block 220 that are connected, the sliding sleeve 210 is slidably sleeved on the outer side of the handle body 100 along the front-back direction, the sliding block 220 extends into the second hole section 112, and a limiting cavity 222 that is communicated with the second hole section 112 forward is provided; the pull rope 300 movably penetrates through the long hole 110, and the rear end of the pull rope 300 is expanded to be limited in the limiting cavity 222; the sleeve body 400 is movably sleeved on the outer side of the inhaul cable 300 and penetrates through the first hole section 111; the rotating sleeve 500 is rotatably sleeved on the outer side of the front section of the handle body 100 along the front-rear axis; wherein, the rear section of the guy cable 300 and the sliding block 220, and/or the rear section of the sleeve body 400 and the first hole section 111 can be selectively engaged in a rotating way or a rotation-stopping way.

In the technical scheme provided by the utility model, the rotation fit or the rotation stop fit can be selectively carried out between the inhaul cable 300 and the sliding block 220 and between the sleeve body 400 and the first hole section 111 respectively, so that when the rotation fit is carried out between the inhaul cable 300 and the sliding block 220 and between the sleeve body 400 and the first hole section 111, the rotation adjustment of the inhaul cable 300 and the sleeve body 400 can not be realized through the relative rotation of the operation handle body 100 and the rotation sleeve 500, and the rotation sleeve is applicable to application occasions without rotating operation of the operation tool 60; when the rotation stopping matching is carried out between the inhaul cable 300 and the sliding block 220 and between the sleeve body 400 and the first hole section 111, the inhaul cable 300, the sleeve body 400 and the handle body 100 are relatively fixed in the rotation direction, and the rotation adjustment of the inhaul cable 300 and the sleeve body 400 can be realized through the relative rotation of the operation handle body 100 and the rotation sleeve 500, so that the rotating device is suitable for application occasions needing to rotate the operation tool 60; when one of the cable 300 and the slider 220, the sleeve 400 and the first hole section 111 are in rotational fit and the other one is in rotational fit, the cable 300 or the sleeve 400 can be selectively rotated and adjusted by the relative rotation of the operation handle body 100 and the rotation sleeve 500. The utility model can provide various operation modes for the inhaul cable 300 and the sleeve body 400, and meet different operation requirements of the operation tool 60, thereby being beneficial to improving the universality and the practicability of the medical handle 10.

In this design, the handle body 100 extends in a longitudinal shape in the front-rear direction, that is, the length direction of the handle body 100 is defined as the front-rear direction. The specific form of the handle body 100 is not limited, and may be configured to have different shapes, different sizes, different materials, etc. according to actual needs. The front end of the handle body 100 is provided with an elongated hole 110, and the elongated hole 110 extends rearward, but generally does not extend through the rear end of the handle body 100.

The sliding sleeve 210 is slidably coupled to the outside of the handle body 100. It can be appreciated that the sliding sleeve 210 is provided with a sliding hole along the front-rear direction, and the sliding sleeve 210 is slidably connected with the handle body 100 through the sliding hole. The sliding sleeve 210 may be configured to have a configuration that facilitates the user's hand holding, for example, to have two grip rings. Since the second hole section 112 penetrates the handle body 100 along the width direction of the handle body 100, the slider 220 can slide in the front-rear direction in the second hole section 112, and the slider 220 can penetrate the second hole section 112 and be connected with the sliding sleeve 210.

The connection mode of the sliding sleeve 210 and the sliding block 220 is not limited, and in order to facilitate disassembly and replacement, the sliding sleeve 210 is detachably connected with the sliding block 220, and the connection mode of the sliding sleeve 210 and the sliding block can be screw connection fixation of a screw connection piece and a threaded hole, magnetic attraction fixation of a magnetic attraction piece and a magnetic matching piece, buckling fixation of a buckling piece and a buckling groove, and the like.

Specifically, for example, one of the joints between the sliding block 220 and the sliding block 210 is provided with a buckle, and the other is provided with a buckle hole, and the sliding block 210 and the sliding block 220 can be connected and fixed through the buckling and the fixing of the buckle and the buckle hole.

The cable 300 penetrates into the elongated hole 110 from the front end of the handle body 100 and extends to the second hole section 112, and the limiting cavity 222 is communicated with the second hole section 112 forward, so that the rear section of the cable 300 can smoothly enter the limiting cavity 222. The rear section of the cable 300 may be expanded, for example, by knotting the rear section of the cable 300, connecting a buckle at the rear section of the cable 300, or the like, so that the width or thickness of the rear section of the cable 300 is greater than the width or thickness of the middle section of the cable 300 connected therewith. Based on this, the width of the limiting cavity 222 in the corresponding direction may be set to be greater than the width or thickness of the rear section of the cable 300, but the thickness or thickness of the connection between the limiting cavity 222 and the second hole section 112 is smaller than the width or thickness of the rear section of the cable 300, so that the rear section of the cable 300 may be limited in the limiting cavity 222, and the rear section of the cable 300 is prevented from falling out from the limiting cavity 222 and the second hole section 112.

When the sliding sleeve 210 drives the sliding block 220 to slide in the front-back direction, the sliding sleeve can act on the rear section of the cable 300, so as to drive the cable 300 to move in the front-back direction as a whole.

The sleeve 400 is movably sleeved on the outer side of the inhaul cable 300, so that the inhaul cable 300 can move back and forth in the sleeve 400. The sleeve body 400 is connected to the first hole section 111, so that the sleeve body 400 is limited at the first hole section 111 at least in the front-back direction, when the cable 300 is driven to move in the front-back direction, the sleeve body 400 is fixed relative to the handle body 100, and therefore the cable 300 can move back and forth relative to the sleeve body 400, and especially when the front end of the cable 300 is connected with the surgical tool 60, the surgical tool 60 can be correspondingly controlled to move. Reference is made in particular to the prior art, without limitation.

Referring to fig. 6, a swivel assembly 500 may generally include a swivel positioning cap 510 and a protective sleeve 520 connected in series from back to front. The rotation positioning cap 510 is connected to the front end of the handle body 100, and is limited at the front end of the handle body 100 in the front-rear direction, and can rotate along the circumferential direction relative to the handle body 100. The protective sleeve 520 is internally threaded with one of the rotational positioning caps 510 and externally threaded with the other. The protective sleeve 520 and the rotary positioning cap 510 are both sleeved outside the sleeve body 400.

In view of the above, the first hole section 111 and/or the rotary sleeve 500 limits the rear section of the sleeve 400 in the front-rear direction, so as to avoid the sleeve 400 from being pulled out of the first hole section 111, and in the circumferential direction of the handle body 100, the rear section of the sleeve 400 and the first hole section 111 may be selectively engaged in a rotating or anti-rotating manner:

wherein, the rear section of the sleeve body 400 can rotate along the front-rear axis in the first hole section 111, and at this time, when the handle body 100 and the rotating sleeve 500 rotate relatively, the sleeve body 400 is not limited by the handle body 100, and thus cannot rotate along with the handle body 100.

The rotation-locking engagement, i.e. the rear section of the sleeve 400, is not rotatable in the first bore section 111 along the longitudinal axis, i.e. the two are fixed relative to each other in this direction. At this time, when the handle body 100 and the rotating sleeve 500 rotate relatively, the sleeve 400 is driven by the handle body 100 to rotate in the same direction, so as to realize the rotation adjustment of the sleeve 400.

Similarly, the sliding block 220 limits the rear section of the cable 300 in a front-back upward manner, so as to avoid the cable 300 from being pulled out of the limiting cavity 222 forward, and in the circumferential direction of the handle body 100, the rear section of the cable 300 and the sliding block 220 can be selectively in running fit or rotation-stopping fit:

the rear section of the cable 300 can rotate along the front-rear axis relative to the slider 220, and at this time, when the handle body 100 and the rotating set 500 rotate relatively, the cable 300 is not limited by the handle body 100, and thus cannot rotate along with the handle body 100.

The detent engagement, i.e., the rear section of the cable 300, is not rotatable relative to the slider 220 along the fore-aft axis, i.e., the two are fixed relative to each other in this direction. At this time, when the handle body 100 and the rotating sleeve 500 rotate relatively, the cable 300 is driven by the handle body 100 to rotate in the same direction, so as to realize the rotation adjustment of the cable 300.

It should be noted that, the above-mentioned anti-rotation fit and rotation fit:

this may be accomplished by switching different mating locations between the same sleeve 400 and the first bore section 111, and/or by switching different mating locations between the same cable 300 and the slider 220.

Or may be achieved by switching different connection strengths between the same sleeve 400 and the first bore section 111, and/or by switching different connection strengths between the same cable 300 and the slider 220.

Or may be achieved by switching between different sleeves 400 to mate with the same portion of the first bore section 111 and/or by switching between different cables 300 to mate with the same portion of the slider 220.

Further, referring to fig. 1 to 4, in an embodiment, one of the hole wall of the first hole section 111 and the outer wall of the rear section of the sleeve 400 is provided with a concave portion 120, and the other is optionally provided with a convex portion. Specifically, taking the hole wall of the first hole section 111 as an example, when the outer wall of the rear section of the sleeve body 400 is provided with a convex part, interference is generated between the concave part 120 and the convex part, so as to limit the sleeve body 400 and the first hole section 111 to generate relative rotation, and the rotation-stopping fit of the two is realized. When the outer wall of the sleeve body 400 is not provided with the convex part, the outer wall of the sleeve body 400 can be a flat cambered surface, and can be partially provided with the groove, and the convex part and the groove can not be interfered, so that the sleeve body 400 and the first hole section 111 can not be limited to relatively rotate, and the running fit between the sleeve body 400 and the first hole section 111 is realized.

Specifically, in an embodiment, the radial cross-sectional shape of the first hole section 111 is polygonal, and the recess 120 is defined between each two adjacent sides of the first hole section 111; the radial cross section of the rear section of the sleeve 400 is polygonal and matched with the first hole section 111, and the convex part is defined between every two adjacent sides of the sleeve 400; or the radial cross section of the rear section of the sleeve 400 is circular. For example, the radial cross-sectional shape of the first hole section 111 is a hexagon in which the angle between the adjacent two sides is not more than 180 ° to constitute the recess 120 described above. Based on this, when the radial cross section of the sleeve 400 is also set to a hexagon, the angle between the adjacent two sides of the hexagon is not less than 180 °, constituting the above-mentioned convex portion. When the radial cross section of the sleeve 400 is circular, no protrusion is formed, and the sleeve 400 can rotate with respect to the first hole section 111.

It should be noted that at least two sleeve bodies 400 may be provided, wherein a radial cross section of one sleeve body 400 is polygonal, a radial cross section of the other sleeve body 400 is circular, and the two sleeve bodies 400 are selected for use to realize rotation or non-rotation of the sleeve body 400. Alternatively, a sleeve body 400 may be provided, the radial sections of two portions along the axial direction of the sleeve body 400 are respectively polygonal and circular, and the sleeve body 400 can be movably adjusted back and forth to a certain extent relative to the first hole section 111, so that the two portions of the sleeve body 400 are respectively matched with the first hole section 111, and finally the sleeve body 400 is rotated or not rotated.

In view of the foregoing, referring to fig. 3 and 7, in an embodiment, the sleeve body 400 includes a sleeve 410 movably sleeved on the outer side of the cable 300, and a sleeve 420 fixedly sleeved on the outer side of the rear section of the sleeve 410, where the sleeve 420 and the first hole section 111 may be selectively engaged in a rotation fit or a rotation-stopping fit. The sleeve 410 and the sleeve 420 can be integrally formed, or can be detachably connected after being separately arranged. The provision of the sleeve 420 helps to increase the strength of the corresponding portion of the sleeve 410 when connected to the first bore section 111. In addition, in practical application, the radial cross-section shape of the sleeve 420 may be polygonal or circular, and the sleeve 420 may be connected to the same sleeve 410 by replacing different sleeves, which is helpful to increase the versatility of the sleeve 400 and reduce the manufacturing cost.

Furthermore, referring to fig. 3 to 5, in an embodiment, the slider 220 includes a main body 221 and two clamping arms 223 protruding from the main body 221 toward the front, where the two clamping arms 223 are disposed at opposite intervals in the width direction of the handle body 100, so as to define a clamping cavity 224 at the interval, and the clamping cavity 224 communicates with the limiting cavity 222; the two clamping arms 223 are movably arranged in directions approaching to and separating from each other, so that the width of the clamping cavity 224 is adjustable, and during the adjustment process, the rear section of the cable 300 and the slider 220 are switched between the rotation-stopping fit and the rotation fit.

The two clamping arms 223 and the main body 221 can be integrally formed and arranged, or can be detachably assembled after being separately arranged. The two grip arms 223 may be provided separately on opposite sides of the handle body 100 in the thickness direction thereof.

The limiting cavity 222 may be defined directly by the body 221; alternatively, the spacing cavity 222 may be defined by two clamping arms 223 together. In addition, the spacing chamber 222 and the clamping chamber 224 may be two independent chambers, which are sequentially communicated from back to front, and the width of the clamping chamber 224 is smaller than the width of the spacing chamber 222, so as not to affect the spacing effect of the spacing chamber 222 on the rear section of the cable 300. Of course, the limiting cavity 222 and the clamping cavity 224 may also be the same cavity, and at this time, when the width of the limiting cavity 222 is smaller than that of the cable 300, the cable 300 may be directly clamped and fixed.

In view of the above, the mutual approaching and mutual distancing of the two gripping arms 223 can be achieved by exchanging different sliders 220. Specifically, for example, the endoscope 1 is preset with at least two types of sliding blocks 220, wherein two clamping arms 223 of one sliding block 220 are far away from each other, and the limiting cavity 222 is defined to limit the cable 300 in the front-back direction, but the limiting cavity 224 is defined to not limit the cable 300 in the rotation stopping direction; the two clamping arms 223 of the other slider 220 are close to each other, the limiting cavity 222 is defined to limit the cable 300 in the front-rear direction, and the limiting cavity 224 is defined to limit the cable 300 in the rotation-stopping direction.

When applied to an embodiment in which the spacing cavity 222 and the clamping cavity 224 share a single cavity, the two types of sliders 220 can be distinguished by a design in which two protrusions are provided on the inner cavity walls of opposite sides of the spacing cavity 222 and two protrusions are not provided.

Of course, the mutual approaching and mutual distancing of the two gripping arms 223 can also be achieved by applying different gripping forces to the same slider 22. When the two clamping arms 223 are driven to approach each other by a larger acting force, the width of the adjustable clamping cavity 224 is reduced, so that the clamping strength of the inhaul cable 300 at the clamping cavity 224 is increased, the inhaul cable 300 is limited to move relative to the sliding block 220 in each direction, and the rotation-stopping fit of the two is realized. When the two clamping arms 223 are driven to move away from each other by a smaller acting force, the width of the adjustable clamping cavity 224 is increased, so that the clamping strength of the inhaul cable 300 at the clamping cavity 224 is reduced, and the inhaul cable 300 can rotate relative to the sliding block 220, so that the two can be in running fit.

Further, in one embodiment, the sliding sleeve 210 is provided with a through hole 211 corresponding to each clamping arm 223 and communicated with the elongated hole 110; the two clamping arms 223 can be elastically deformed in directions approaching to and separating from each other, each clamping arm 223 is convexly provided with a pressing protrusion 225, and the pressing protrusion 225 is inserted into the corresponding through hole 211 so as to drive the corresponding clamping arm 223 to elastically deform under the action of external force.

There are various ways to realize the elastic deformation setting of the clamping arms 223 in the directions approaching and separating from each other, for example, at least two clamping arms 223 on the setting slider 220 are made of elastic materials, for example, rubber materials, silica gel materials, etc.; the two clamping arms 223 may also be provided as sheet metal, which also has a certain elastic deformability. Alternatively, the main body 221 and the grip arm 223 may be rotatably connected, and the connection therebetween is elastically pulled by an elastic member such as a spring.

When the through hole 211 and the pressing protrusion 225 are not pressed, the through hole 211 may form the fastening hole structure, the pressing protrusion 225 may form the fastening structure, and the two structures are fastened and fixed, so as to connect the slider 220 and the sliding sleeve 210. When the clamping strength of the two clamping arms 223 to the cable 300 needs to be increased, the pressing protrusion 225 at the position of at least one clamping arm 223 can be pressed, so that the clamping arm 223 is driven to be close to the other clamping arm 223, the dimension of the clamping cavity 224 in the corresponding direction (namely, the width of the uniformly named clamping cavity 224) is reduced, and the operation is simple.

Further, based on any of the above embodiments, at least a portion of the swivel assembly 500 connected to the handle body 100 is made of an elastic material. The arrangement is such that when the rotary sleeve 500 (such as the rotary positioning cap 510) is deformed and expanded by an external force, the sleeve is smoothly connected to the front section of the handle body 100, and the deformation is recovered after the external force is removed, so as to connect with the handle body 100.

And/or, the outer wall of the handle body 100 at least at the portion connected to the rotation kit 500 is made of an elastic material. The arrangement is such that when the rotary sleeve 500 (such as the rotary positioning cap 510) is sleeved on the front section of the handle body 100, the handle body 100 can shrink and deform under the action of external force to complete adjustment in a forestation manner, and the rotary sleeve 500 and the handle body 100 can be connected by recovering the deformation after the external force is removed.

In particular, in an embodiment, please refer to fig. 2 to fig. 4, the front end of the handle body 100 is concavely provided with an annular avoidance groove 130 at the periphery of the first hole section 111, so as to divide the front section of the handle body 100 into an inner handle body 141 and an outer handle body 142 that are sleeved inside and outside, and a notch 143 that is communicated with the annular avoidance groove 130 is provided on the outer wall of the outer handle body 142, so that the outer handle body 142 can bend and deform towards and away from the inner handle body 141 under the action of external force. In this way, it is not only helpful to ensure that the inner shank 141 has enough strength to form the first hole section 111, but also to ensure that the connection between the first hole section 111 and the sleeve 400 is stable; and the outer handle body 142 is also facilitated to elastically bend and deform under the action of external force.

Next, in one embodiment, one of the joints between the handle body 100 and the rotating set 500 is provided with a sliding protrusion 511, and the other is provided with an annular sliding groove 150, and the sliding protrusion 511 is slidably engaged with the annular sliding groove 150. The sliding protrusion 511 can slide along the annular chute 150 to assist in stabilizing the rotation of the swivel assembly 500 relative to the handle body 100. In addition, since the annular chute 150 is formed on the outer wall of the handle body 100, two limiting walls are formed on two opposite side walls of the annular chute 150 in the front-rear direction, so that the sliding protrusion 511 can be limited forward and backward, the sliding protrusion 511 is prevented from being separated from the annular chute 150, and the rotating sleeve 500 is prevented from being separated from the handle body 100.

In addition, the utility model also provides a medical apparatus 1, the medical apparatus 1 comprises the medical handle 10 and the surgical tool 60, the front end of the guy cable 300 extends out of the sleeve 400, and the surgical tool 60 is connected with the front end of the guy cable 300.

It should be noted that, the detailed structure of the medical handle 10 in the medical apparatus 1 may refer to the above embodiment of the medical handle 10, and will not be described herein again; because the medical device 1 of the present application uses the medical handle 10, the embodiments of the medical device 1 of the present application include all the technical solutions of all the embodiments of the medical handle 10, and the achieved technical effects are identical, and are not described in detail herein.

In particular applications, the surgical tool 60 may be embodied as a snare, a stone retrieval basket, a medical clamp, or the like, without limitation.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
