Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical handpiece and surgical power device. Background Technology

[0002] In the field of modern surgery, minimally invasive surgical instruments play a crucial role in tissue removal procedures. For example, traditional shaving tools are widely used for cutting soft tissues in areas such as the ear, nose, and throat. During surgery, a handle is usually attached, and the surgeon controls the shaving tool by manipulating the handle to complete the surgical procedure.

[0003] However, existing surgical instruments have certain limitations in circumferential orientation adjustment. In traditional surgical instrument use, when adjusting the circumferential orientation of the instrument is required, the surgeon needs to drag a long cable and rotate the entire handle. This process places high demands on the surgeon's manual dexterity, increasing not only the complexity of the surgery but also significantly increasing the surgeon's workload. Furthermore, due to the limitations in cable length and handle rotation range, the flexibility of surgical manipulation and the precision with which the instrument acts on tissue are both affected to some extent. Utility Model Content

[0012] In one embodiment, the orientation component includes:

[0013] An operating sleeve, movably fitted around the outer periphery of the handle body; and

[0014] A transmission sleeve is fixedly disposed inside the operating sleeve, and the transmission sleeve is circumferentially fixed to the mounting assembly;

[0015] The operating sleeve is operable to reciprocate along the axial direction of the handle body, so as to lock or unlock the transmission sleeve to the handle body.

[0016] In one embodiment, a second concave-convex insertion structure is provided between the transmission sleeve and the operating sleeve, and the transmission sleeve and the operating sleeve are circumferentially fixed relative to each other through the second concave-convex insertion structure.

An axial limiting surface is provided on the handle body, a limiting step surface is provided inside the operating sleeve, and a limiting sleeve and an elastic element are provided on the outer periphery of the protrusion. The elastic element abuts against the transmission sleeve and the limiting sleeve respectively, so that the transmission sleeve abuts against the limiting step surface and drives the adjusting assembly to remain in the locked position abutting against the axial limiting surface.

[0018] In one embodiment, the handle body is provided with an axial limiting surface, which abuts against the adjusting component to limit the axial limit position of the adjusting component's movement toward the locking position.

[0019] In one embodiment, a cavity is formed inside the handle body, the mounting assembly is disposed in the cavity, and the mounting assembly has a protrusion extending out of the front end of the handle body, and the directional assembly is circumferentially fixed relative to the protrusion.

[0020] In one embodiment, the medical handle further includes a locking assembly, which includes a limiting sleeve and an elastic element. The limiting sleeve is fitted around the outer periphery of the protrusion. The elastic element abuts against the limiting sleeve and the adjusting assembly in the axial direction to drive the adjusting assembly to remain in the locked position.

[0021] In one embodiment, the medical handle further includes a positioning element disposed between the protrusion and the adjusting component to circumferentially fix the mounting component and the adjusting component.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0045] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0047] In traditional surgical instrument use, when adjusting the circumferential orientation of the instrument, the surgeon needs to drag a long cable, causing the entire handle to rotate. This process places high demands on the surgeon's manual dexterity, increasing not only the complexity of the surgery but also significantly increasing the workload. Furthermore, due to the limitations of cable length and handle rotation range, the flexibility of surgical manipulation and the precision with which the instrument acts on tissue are both affected to some extent.

[0048] This utility model proposes a medical handle.

[0049] Please see Figure 1 In one embodiment of this utility model, the medical handle 100 includes:

[0050] Handle body 1;

[0051] Mounting component 2 is rotatably sleeved with handle body 1 and is fixed relative to the axial position of handle body 1. Mounting component 2 is used to mount the cutting tool.

[0052] The directional component 3 is movably sleeved on the outer periphery of the handle body 1 and is circumferentially fixed relative to the mounting component 2;

[0053] The directional component 3 has two circumferential positions along its own axial direction, including a locked position and an unlocked position. When the directional component 3 is in the locked position, it is circumferentially locked to the handle body 1. When the directional component 3 is in the unlocked position, it is circumferentially unlocked to the handle body 1, so that the mounting component 2 can rotate circumferentially relative to the handle body 1 with the directional component 3.

[0054] The technical solution of this utility model adopts a circumferential positioning-axial unlocking motion mechanism. By moving the directional component 3 axially between the locked and unlocked positions, the circumferential degree of freedom of the mounting component 2 is switched. When the directional component 3 slides to the locked position, the directional component 3 and the handle body 1 are in a circumferentially fixed state, and the mounting component 2 is also fixed along with the directional component 3. At this time, the tool cannot rotate to adjust its direction. When the directional component 3 slides to the unlocked position, the directional component 3 and the handle body 1 are in a circumferentially unlocked state. The directional component 3 and the mounting component 2 can rotate synchronously relative to the circumference of the handle body 1, so that the mounting component 2 drives the tool to adjust according to the target angle. No large rotational force needs to be applied during the entire operation, which significantly improves the convenience of surgical operation.

[0055] Optionally, the orientation component 3 integrates an angle scale ring, which facilitates more precise adjustment of the circumferential angle of the tool, making it particularly suitable for delicate surgical scenarios such as neurosurgery. Additionally, the mounting component 2 has an internal tool mounting channel and a quick-change interface at its front end for rapid insertion and fixation.

[0056] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 A first concave-convex insertion structure 7 is provided between the directional component 3 and the handle body 1, allowing the directional component 3 and the handle body 1 to be inserted into or separated via the first concave-convex insertion structure 7. The first concave-convex insertion structure 7 includes a cooperating first protrusion 71 and a first groove 72. One of the directional component 3 and the handle body 1 has a first protrusion 71, and the other has a first groove 72. At least one of the first protrusions and the first grooves is distributed in multiple circumferentially, so that the directional component 3 can be locked to multiple circumferential positions of the handle body 1. Furthermore, the structure of the first protrusion and the first groove is not specifically limited. The first protrusion can be a trapezoidal tooth or a circular arc tooth, and the first groove can be a trapezoidal groove or a circular arc groove, respectively. For example, the directional component 3 may be provided with a first protrusion 71, the first protrusion 71 having a guide surface, and the front end of the handle body 1 having a plurality of first grooves 72 evenly distributed along the circumference. In this way, no matter which circumferential position the directional component 3 rotates to, the first protrusion 71 can move axially with the directional component 3 and smoothly embed into the corresponding first groove 72, thereby locking the directional component 3 and the handle body 1 circumferentially.

[0057] Of course, in order to achieve "when the adjusting component 3 is in the locked position, the adjusting component 3 is circumferentially locked to the handle body 1, and when the adjusting component 3 is in the unlocked position, the adjusting component 3 is circumferentially unlocked to the handle body 1", other first concave-convex insertion structures 7 can also be used. For example, a separable key and keyway can also be used.

[0058] In some embodiments, the directional assembly 3 is an integral structure composed of a single part; of course, the directional assembly 3 may also be a combination of multiple parts.

[0059] In one embodiment, please refer to Figures 1 to 3 The directional component 3 includes:

[0060] Operating sleeve 31 is movably fitted around the outer periphery of handle body 1; and

[0061] The transmission sleeve 32 is fixedly disposed inside the operating sleeve 31, and the transmission sleeve 32 is circumferentially fixed to the mounting assembly 2;

[0062] The operating sleeve 31 can be operably slid back and forth along the axial direction of the handle body 1 to lock or unlock the transmission sleeve 32 to the handle body 1.

[0063] Specifically, the directional adjustment component 3 consists of an operating sleeve 31 and a transmission sleeve 32 fitted together. The transmission sleeve 32 moves synchronously back and forth along the axial direction of the handle body 1, thus enabling the transmission sleeve 32 to be engaged and locked or disengaged from the end of the handle body 1. That is, when the direction of the tool needs to be adjusted, the user can slide the operating sleeve 31 to the left, which will cause the transmission sleeve 32 to move synchronously to the left, thereby disengaging from the handle body 1. At this time, the rotation of the transmission sleeve 32 and the operating sleeve 31 will cause the mounting component 2 to rotate synchronously. When the direction of the tool needs to be fixed, the user can slide the operating sleeve 31 to the right, which will cause the transmission sleeve 32 to move synchronously to the right, thereby engaging and locking with the handle body 1. At this time, the transmission sleeve 32 is fixed to the end of the handle body 1, and the mounting component 2 is also fixed accordingly, making it impossible to adjust the tool.

[0064] Specifically, "the transmission sleeve 32 is fixedly disposed inside the operating sleeve 31," meaning that the transmission sleeve 32 is circumferentially and axially fixed relative to the operating sleeve 31. In this embodiment of the invention, to achieve the relative fixation between the transmission sleeve 32 and the operating sleeve 31, please refer to... Figure 3 and Figure 4 A second concave-convex insertion structure 8 is provided between the transmission sleeve 32 and the operating sleeve 31, and the transmission sleeve 32 and the operating sleeve 31 are circumferentially fixed relative to each other by the second concave-convex insertion structure 8. Similarly, the second concave-convex insertion structure 8 includes a matching second protrusion 81 and a second groove 82. One of the transmission sleeve 32 and the operating sleeve 31 is provided with the second protrusion 81, and the other is provided with the second groove 82. In addition, the structure of the second protrusion and the second groove is not specifically limited. The second protrusion can be a trapezoidal tooth or a circular arc tooth, etc., and the second groove can be a trapezoidal groove or a circular arc groove, etc., respectively. For example, the outer wall of the transmission sleeve 32 near the end face is provided with the second groove 82, and the operating sleeve 31 is provided with the corresponding second protrusion 81.

[0065] Of course, in order to achieve "the transmission sleeve 32 and the mounting component 2 are circumferentially fixed" and to satisfy "the adjusting component 3 is movably sleeved on the outer periphery of the handle body 1", other methods can also be used. For example, the transmission sleeve 32 and the mounting component 2 can adopt a nested sleeve structure, and a key structure, such as a spline or a flat key, can be provided on the mating surface of the two.

[0066] In the embodiments of this utility model, please refer to Figure 2The handle body 1 has an internal cavity, and the mounting assembly 2 is disposed within the cavity. The mounting assembly 2 has a protrusion extending out of the front end of the handle body 1, and the transmission sleeve 32 is circumferentially fixed relative to the protrusion. Specifically, the end of the protrusion may be provided with a fork groove or a slot for engaging and fixing with a fork or claw on a tool. In order to achieve axial fixation of the transmission sleeve 32 relative to the operating sleeve 31, the handle body 1 is provided with an axial limiting surface 11, the operating sleeve 31 is provided with a limiting step surface 311, and the outer periphery of the protrusion is provided with a limiting sleeve 41 and an elastic element 42. The elastic element 42 abuts against the transmission sleeve 32 and the limiting sleeve 41 respectively, so that the transmission sleeve 32 abuts against the limiting step surface 311 and drives the adjusting assembly 3 to remain in the locked position abutting against the axial limiting surface 11. The axial limiting surface 11 and the limiting step surface 311 can be annular planes, the limiting sleeve 41 can be a thin-walled cylinder, and the elastic element 42 can be a cylindrical spring. The two ends of the spring abut against the transmission sleeve 32 and the limiting sleeve 41, respectively. Under the elastic tension of the spring, the end face of the transmission sleeve 32 and the limiting step surface 311 of the operating sleeve 31 always remain in contact, thus driving the operating sleeve 31 to always press against the axial limiting surface 11 on the handle body 1, maintaining it in the locked position. When the operating sleeve 31 needs to be unlocked, simply compress the spring to overcome its elastic force and separate the operating sleeve 31 from the axial limiting surface 11.

[0067] In the embodiments of this utility model, please refer to Figure 2 The handle body 1 is provided with an axial limiting surface 11, which abuts against the adjusting component 3 to limit the axial limit position of the adjusting component 3 to move towards the locking position. The axial limiting surface 11 can be an annular plane, or it can have rounded corners at the edges.

[0068] In the embodiments of this utility model, please refer to Figure 2 The handle body 1 has a cavity inside, the mounting component 2 is located in the cavity, and the mounting component 2 has an extension that extends out of the front end of the handle body 1. The adjusting component 3 is circumferentially fixed to the extension.

[0069] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The medical handle 100 also includes a locking assembly 4, which includes a limiting sleeve 41 and an elastic element 42. The limiting sleeve 41 is fitted onto the outer periphery of the protrusion. The elastic element 42 abuts against the limiting sleeve 41 and the adjusting assembly 3 in the axial direction to keep the adjusting assembly 3 in the locked position. The limiting sleeve 41 is fitted onto the outer periphery of the end of the protrusion. Through the elastic tension of the elastic element 42, the adjusting assembly 3 can be kept pressed against the handle body 1 and held in the locked position.

[0070] In the embodiments of this utility model, see Figure 1 , Figure 2 and Figure 5 The protruding part is generally hollow cylindrical. A receiving groove 210 is provided on the outer wall of the protruding part, and a locking ball 6 is provided inside the receiving groove 210. A movable groove 411 can also be provided on the inner wall of the limiting sleeve 41. When the limiting sleeve 41 is in the locked state, it blocks the receiving groove 210. The receiving groove 210 and the movable groove 411 are staggered, and the locking ball 6 is fixed inside the receiving groove 210. At this time, the mounting assembly 2 is fixed by the limiting sleeve 41 and cannot move. Furthermore, the locking ball 6 extends into the hollow space inside the protruding part and can... The locking groove on the tool is used to lock the tool (not shown in the figure). When the tool needs to be disassembled or assembled, the limiting sleeve 41 can be slid to the right to compress the elastic element 42 to overcome the elastic force of the elastic element 42, so that the movable groove 411 is connected to the receiving groove 210. The locking ball 6 can move within the space between the movable groove 411 and the receiving groove 210. At this time, by inserting or removing the tool, the locking ball 6 can be pushed to move towards the movable groove 411 to exit the internal hollow space of the protrusion, so that the tool can be inserted or removed from the protrusion.

[0071] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 6 The medical handle 100 also includes a positioning element 5, which is located between the protrusion and the adjusting component 3 to circumferentially fix the mounting component 2 and the adjusting component 3. The positioning element 5 can be a spline, a flat key, or other structures with circumferential positioning function. The phrase "the positioning element 5 is located between the protrusion and the adjusting component 3" means that the positioning element 5 can be located on the outer wall of the protrusion, on the inner wall of the adjusting component 3, or partially on the protrusion and partially on the adjusting component 3, depending on the specific design requirements.

[0072] In the embodiments of this utility model, please refer to Figure 2 The positioning element 5 is a ball bearing. The inner wall of the directional component 3 is provided with a positioning groove, and the outer wall of the protrusion is provided with a guide groove extending in the axial direction. The ball bearing is simultaneously fitted in the positioning groove and the guide groove. In this way, when the directional component 3 moves in the axial direction of the handle body 1, the ball bearing will move synchronously with the directional component 3 in the guide groove. This can realize the reciprocating sliding of the directional component 3 in the axial direction of the handle body 1, while satisfying the requirement that the directional component 3 and the mounting component 2 be circumferentially fixed.

[0073] Alternatively, in another embodiment, the positioning element 5 is a ball bearing, the inner wall of the adjusting component 3 is provided with a guide groove extending in the axial direction, and the outer wall of the protrusion is provided with a positioning groove. The ball bearing is simultaneously fitted in the positioning groove and the guide groove. In this way, when the adjusting component 3 moves in the axial direction of the handle body 1, the ball bearing will not move with the movement of the adjusting component 3, and the setting of the guide groove provides a space for the ball bearing to be accommodated.

[0074] Alternatively, in another embodiment, the positioning member 5 is fixedly disposed on the directional assembly 3, and the outer wall of the protrusion is provided with a guide groove extending in the axial direction, and the positioning member 5 is fitted in the guide groove; for example, a fixed positioning member 5 can be used, such as a cylindrical pin, which is fixed to the inner wall of the directional assembly 3, and a dovetail-shaped guide groove is provided on the outer wall of the protrusion. The synchronous movement of the positioning member 5 is driven by the movement of the directional assembly 3 to ensure the accuracy of the axial movement of the directional assembly 3.

[0075] Alternatively, in another embodiment, the positioning member 5 is fixedly disposed on the protrusion, and the inner wall of the adjusting component 3 is provided with a guide groove extending in the axial direction, with the positioning member 5 fitting within the guide groove. In this embodiment, the positioning member 5 is fixedly disposed on the outer wall of the protrusion, and the positioning member 5 can be a guide rail, allowing the adjusting component 3 to move along the guide rail.

[0076] In the embodiments of this utility model, please refer to Figure 2 and Figure 6 The cavity contains a stop step 12. The mounting assembly 2 includes a mounting sleeve 21 and a protective sleeve 22. The protective sleeve 22 is fitted around the outer periphery of the mounting sleeve 21 and fits into the cavity. The protective sleeve 22 has a flange 221, and the mounting sleeve 21 has a limiting shoulder 211. The flange 221 abuts against the stop step 12 and the limiting shoulder 211, respectively. Specifically, the flange 221 is provided at the end of the protective sleeve 22 near the stop step 12. This structure, with the protective sleeve 22, helps to prevent the mounting sleeve 21 from sticking to the handle body 1 due to rust. Optionally, the protective sleeve 22 can be made of PEEK material.

[0077] Optionally, multiple recesses may be provided on the surface of the gear shift step 12, and protrusions may be provided on the surface of the flange 221 facing the gear shift step 12. The installation stability of the protective cover 22 inside the handle body 1 is improved by the cooperation of the protrusions and the recesses.

[0078] This utility model also proposes a surgical power device 200, please refer to [link / reference]. Figure 7 The surgical power device 200 includes a compatible medical cutting tool 201 and a medical handle 100. The specific structure of the medical handle 100 is as described in the above embodiments. Since this surgical power device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
