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 terms of circumferential adjustment. Some surgical instruments rely on rotating the entire handle for circumferential adjustment, which requires dragging the cable at the end of the handle, making operation inconvenient. Other surgical instruments rely on a circumferential adjustment mechanism on the operating handle for axial adjustment. However, in actual operation, there is a risk of the instrument becoming loose due to accidental activation of the locking mechanism while operating the adjustment mechanism, which could affect surgical safety. Utility Model Content

[0004] The main purpose of this invention is to propose a medical handle and surgical power device, which aims to solve the problem that the cutting tool may easily come loose due to accidental contact with the cutting tool locking structure during the adjustment process.

[0005] To achieve the above objectives, the present invention provides a medical handle, the medical handle comprising:

[0006] handle body;

[0007] The mounting component is sleeved with the handle body and is fixed relative to the axial position of the handle body, and has a tool mounting channel for mounting tools.

[0008] A directional adjustment component is movably fitted around the outer periphery of the handle body and circumferentially fixed to the mounting component. The directional adjustment component has two circumferentially locked and unlocked positions along the axial direction of the mounting component. When the directional adjustment component is in the circumferentially locked position, it is circumferentially locked to the handle body. When the directional adjustment component is in the circumferentially unlocked position, it is circumferentially unlocked from the handle body, allowing the mounting component to rotate circumferentially relative to the handle body with the directional adjustment component.

[0009] The locking assembly includes a first operating sleeve movably sleeved on the periphery of the mounting assembly. The first operating sleeve moves along the axial direction of the mounting assembly to lock or unlock a tool in the tool mounting channel. The movable positions of the first operating sleeve along its own axial direction include a tool locking position and a tool unlocking position.

[0010] When the directional component is in the circumferential unlocked position, the directional component tends to press against the locking component toward the tool locking position, so that the locking component remains in the tool locking position.

[0011] In one embodiment, the medical handle further includes an elastic element disposed between the adjusting component and the first operating sleeve, so that the first operating sleeve and the adjusting component are respectively held in the tool locking position and the circumferential locking position when not in operation;

[0012] When the first operating sleeve is in the tool unlock position, the elastic element pushes the adjusting component to remain in the circumferential locking position.

[0013] In one embodiment, an installation cavity is formed between the first operating sleeve and the installation component, and the elastic element is disposed within the installation cavity.

[0014] In one embodiment, the handle body has a cavity, the mounting assembly is disposed in the cavity, and the mounting assembly has a protrusion extending forward out of the cavity. The steering assembly is partially sleeved on the outer periphery of the protrusion, and the first operating sleeve is sleeved on the outer periphery of the protrusion.

[0015] In one embodiment, the locking assembly further includes a limiting member, which is disposed on the outer periphery of the protrusion and is axially fixed relative to the mounting assembly. The limiting member is disposed on the side of the first operating sleeve that is axially away from the adjusting assembly, so that the first operating sleeve abuts against the limiting member when it is in the tool locking position.

[0016] In one embodiment, the mounting assembly includes a mounting sleeve, the side wall of which is provided with a receiving groove, and the locking assembly further includes a locking member disposed in the receiving groove, the locking member being able to partially extend into or out of the tool mounting channel to lock or unlock the tool in the tool mounting channel;

[0017] When the first operating sleeve is in the tool unlocking position, the first operating sleeve avoids the path of the locking member exiting the tool mounting channel, thereby unlocking the tool;

[0018] When the first operating sleeve is in the tool locking position, the first operating sleeve blocks the path of the locking member exiting the tool mounting channel to lock the tool.

[0019] In one embodiment, the inner wall of the first operating sleeve is provided with a movable groove and a blocking portion adjacent to each other along the axial direction. When the first operating sleeve is in the tool unlocking position, the position of the movable groove corresponds to the position of the receiving groove, so that the locking member can be partially retracted into the movable groove. When the first operating sleeve is in the tool locking position, the position of the blocking portion corresponds to the position of the receiving groove.

[0020] In one embodiment, a first concave-convex insertion structure is provided between the steering component and the handle body, and the steering component and the handle body can be inserted or separated through the first concave-convex insertion structure.

[0021] In some embodiments, the first protrusion-recessed structure includes a first protrusion and a first groove that cooperate. One of the directional assembly and the handle body is provided with the first protrusion, and the other is provided with the first groove. At least one of the first protrusion and the first groove is distributed in multiple circumferentially, so that the directional assembly can be locked to multiple circumferential positions of the handle body.

[0022] In one embodiment, the orientation component includes:

[0023] The second operating sleeve is movably fitted onto the outer periphery of the handle body; and

[0024] A transmission sleeve is fixedly disposed inside the second operating sleeve, and the transmission sleeve is circumferentially fixed to the mounting assembly;

[0025] The second 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.

[0026] To achieve the above objectives, this utility model also proposes a surgical power device, which includes a compatible medical handle and a medical blade, wherein the medical handle is the medical handle described in any of the above embodiments.

[0027] The technical solution of this utility model adopts a cooperative mechanism of directional adjustment component and locking component, which realizes that while the directional adjustment component adjusts the tool direction, it can also drive the locking component to lock the tool, significantly improving the tool's fixing strength. The axial movement of the directional adjustment component between the circumferential locking position and the circumferential unlocking position achieves the switching of the circumferential degree of freedom of the mounting component. When the directional adjustment component slides to the circumferential locking position, the directional adjustment component and the handle body are in a circumferentially locked state, and the mounting component is also fixed along with the directional adjustment component. At this time, the tool cannot rotate to adjust its direction. When the directional adjustment component slides to the circumferential unlocking position, the directional adjustment component and the handle body are in a circumferentially unlocked state. The directional adjustment component and the mounting component can rotate synchronously relative to the circumference of the handle body, allowing the mounting component to drive the tool to adjust according to the target angle. In addition, the tool is locked or unlocked by the reciprocating motion of the first operating sleeve in the locking assembly along the axial direction of the mounting assembly. When the directional assembly is in the circumferential unlocked position, the directional assembly tends to press against the locking assembly towards the tool locking position, so that the locking assembly is kept in the tool locking position, ensuring that the tool is always stable during the direction adjustment process, eliminating the risk of tool loosening or even falling off due to rotation operation, and improving the safety of operation.

[0043] Existing surgical instruments have certain limitations in terms of circumferential adjustment. Some surgical instruments rely on rotating the entire handle for circumferential adjustment, which requires dragging the cable at the end of the handle, making operation inconvenient. Other surgical instruments rely on a circumferential adjustment mechanism on the operating handle for axial adjustment. However, in actual operation, there is a risk of the instrument becoming loose due to accidental activation of the locking mechanism while operating the adjustment mechanism, which could affect surgical safety.

[0044] This utility model proposes a medical handle.

[0045] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the medical handle 100 includes:

[0046] Handle body 1;

[0047] Mounting component 2 is sleeved with handle body 1 and is fixed relative to the axial position of handle body 1, and has a tool mounting channel for mounting tools.

[0048] The adjusting component 3 is movably sleeved on the outer periphery of the handle body 1 and circumferentially fixed to the mounting component 2. The adjusting component 3 has two circumferentially locked and unlocked positions along the axial direction of the mounting component 2. When the adjusting component 3 is in the circumferentially locked position, it is circumferentially locked to the handle body 1. When the adjusting component 3 is in the circumferentially unlocked position, it is circumferentially unlocked from the handle body 1, allowing the mounting component 2 to rotate circumferentially relative to the handle body 1 with the adjusting component 3.

[0049] The locking assembly 4 includes a first operating sleeve 41 that is movably sleeved on the outer periphery of the mounting assembly 2. The first operating sleeve 41 moves along the axial direction of the mounting assembly 2 to lock or unlock the tool in the tool mounting channel. The movable positions of the first operating sleeve 41 along its own axial direction include a tool locking position and a tool unlocking position.

[0050] The technical solution of this utility model adopts a cooperative mechanism of adjusting component 3 and locking component 4, which realizes the effect of adjusting component 3 adjusting the tool direction while simultaneously driving locking component 4 to lock the tool. The axial movement of adjusting component 3 between the circumferential locking position and the circumferential unlocking position achieves the switching of the circumferential degree of freedom of mounting component 2. When adjusting component 3 slides to the circumferential locking position, adjusting component 3 and handle body 1 are in a circumferentially locked state, and mounting component 2 is also fixed along with adjusting component 3. At this time, the tool cannot rotate to adjust its direction. When adjusting component 3 slides to the circumferential unlocking position, adjusting component 3 and handle body 1 are in a circumferentially unlocked state. Adjusting component 3 and mounting component 2 can rotate synchronously relative to the circumference of handle body 1, allowing mounting component 2 to drive the tool to adjust according to the target angle. In addition, the locking assembly 41 reciprocates along the axial direction of the mounting assembly 2 by the first operating sleeve 41 in the locking assembly 4, thereby locking or unlocking the tool; when the adjusting assembly 3 is in the circumferential unlocked position, the adjusting assembly 3 tends to press against the locking assembly 4 towards the tool locking position, so that the locking assembly 4 is kept in the tool locking position, ensuring that the tool is always stable during the direction adjustment process, eliminating the risk of tool loosening or even falling off due to rotation operation, and improving surgical safety.

[0051] 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 and otolaryngology.

[0052] In the embodiments of this utility model, please refer to Figure 1 and Figure 2The medical handle 100 also includes an elastic element 5, which is disposed between the adjusting component 3 and the first operating sleeve 41, so that the first operating sleeve 41 and the adjusting component 3 are respectively held in the tool locking position and the circumferential locking position when not in operation; when the first operating sleeve 41 is in the tool unlocking position, the elastic element 5 pushes the adjusting component 3 to be held in the circumferential locking position. In this design, the elastic element 5 can be a cylindrical spring. The two ends of the spring are respectively aligned with the adjusting component 3 and the first operating sleeve 41. When the user does not operate the spring, due to the elastic tension at both ends of the spring, the elastic force at one end of the spring causes the end face of the adjusting component 3 away from the first operating sleeve 41 to always keep in contact with the end face of the handle body 1. The elastic force at the other end of the spring causes the first operating sleeve 41 to tend to move away from the adjusting component 3, and always remain in the tool locking position. When it is necessary to install or remove the tool when the user does not operate the spring, the first operating sleeve 41 can be slid to the right to compress the elastic element 5 to overcome the elastic force, and the first operating sleeve 41 can be switched from the tool locking position to the tool unlocking position.

[0053] In the embodiments of this utility model, please refer to Figure 1 An installation cavity is formed between the first operating sleeve 41 and the installation component 2, and the elastic element 5 is disposed in the installation cavity. In this solution, the first operating sleeve 41 and the installation component 2 are arranged axially at intervals to leave installation space for the elastic element 5. Of course, an annular hole can also be drilled on the inner wall of the first operating sleeve 41 or the outer wall of the installation component 2, and the elastic element 5 can be placed in the annular hole.

[0054] In the embodiments of this utility model, please refer to Figure 2 The handle body 1 has a cavity, the mounting component 2 is located in the cavity, and the mounting component 2 has a protrusion that extends forward out of the cavity. The adjusting component 3 is partially sleeved on the outer periphery of the protrusion, and the first operating sleeve 41 is sleeved on the outer periphery of the protrusion.

[0055] In the embodiments of this utility model, please refer to Figures 1 to 3 The locking assembly 4 also includes a limiting member 42, which is located on the outer periphery of the protrusion and is axially fixed relative to the mounting assembly 2. The limiting member 42 is located on the side of the first operating sleeve 41 facing away from the adjusting assembly 3 along the axial direction, so that the first operating sleeve 41 abuts against the limiting member 42 when it is in the tool locking position. The limiting member 42 can be a ring structure, which can fit well on the outer periphery of the protrusion. The limiting member 42 is located on the side of the first operating sleeve 41 facing away from the adjusting assembly 3 along the axial direction, so that when the tool needs to be locked, the adjusting assembly 3 can press the first operating sleeve 41 against the limiting member 42, keeping the first operating sleeve 41 in the locked position. This helps to ensure that the tool remains in a stable locked state throughout the entire operation, reducing the risk of the tool loosening or falling off.

[0056] In the embodiments of this utility model, please refer to Figure 4 The mounting assembly 2 includes a mounting sleeve 21, which is a hollow cylindrical shape with a receiving groove 211 on its side wall. The locking assembly 4 also includes a locking member 43 disposed within the receiving groove 211. The locking member 43 can partially extend into or retract from the tool mounting channel to lock or unlock the tool within the tool mounting channel. When the first operating sleeve 41 is in the tool unlocking position, it avoids the path of the locking member 43 exiting the tool mounting channel, allowing the locking member 43 to smoothly and partially exit the tool mounting channel, thus unlocking the tool. When the first operating sleeve 41 is in the tool locking position, it blocks the path of the locking member 43 exiting the tool mounting channel, forming a reliable physical barrier. Notably, the tool adapted within the tool mounting channel (not shown) is provided with a locking groove (not shown) for the locking member 43 to engage with. Thus, the locking member 43 locks the tool by entering or retracting from the locking groove. This structure enables quick tool installation and removal. Please refer to [link to relevant documentation]. Figure 4 The mounting assembly 2 may further include a protective sleeve 22, which is fitted around the outer periphery of the mounting sleeve 21 and fits within the cavity. The protective sleeve 22 has a flange 221, and the mounting sleeve 21 has a limiting shoulder 212. The flange 221 abuts against the stop step 12 and the limiting shoulder 212, respectively. Specifically, the flange 221 is provided at one end of the protective sleeve 22 near the stop step 12. This structure, with the protective sleeve 22, helps prevent the mounting sleeve 21 from sticking to the handle body 1 due to rust. Optionally, the protective sleeve 22 may be made of PEEK material.

[0057] In the embodiments of this utility model, please refer to Figure 1The inner wall of the first operating sleeve 41 is provided with a movable groove 411 and a retaining part 412 adjacent to each other along the axial direction. When the first operating sleeve 41 is in the tool unlocking position, the position of the movable groove 411 corresponds to the position of the receiving groove 211, so that the locking member 43 can be partially retracted into the movable groove 411. When the first operating sleeve 41 is in the tool locking position, the position of the retaining part 412 corresponds to the position of the receiving groove 211. In order to realize that "the movable position of the first operating sleeve 41 along its own axial direction includes the tool locking position and the tool unlocking position", and to ensure that the switching between the tool unlocking position and the tool locking position can be realized by the axial movement of the first operating sleeve 41, the inner wall of the first operating sleeve 41 can also be provided with a movable groove 411. When the first operating sleeve 41 is in the tool locking position, the retaining part 412 of the first operating sleeve 41 blocks the receiving groove 211. The receiving groove 211 and the movable groove 411 are staggered in the axial direction, and the locking member 43 is fixed inside the receiving groove 211. At this time, the mounting assembly 2 is fixed by the first operating sleeve 41. The locking element 43 is fixed and cannot move, and extends into the tool mounting channel, engaging with the locking groove on the tool to lock it in place (not shown). When the tool needs to be installed or removed, the first operating sleeve 41 can be slid to the right, compressing the elastic element 5 to overcome its elastic force, so that the movable groove 411 and the receiving groove 211 are connected. The locking element 43 can move within the space between the movable groove 411 and the receiving groove 211. At this time, by inserting or removing the tool, the locking element 43 can be pushed towards the movable groove 411 to exit the tool mounting channel, allowing the tool to be inserted into or removed from the tool mounting channel. In this embodiment, the locking element 43 can be a ball bearing or other easily rolling structure.

[0058] In the embodiments of this utility model, please refer to Figure 2 and Figure 5A first concave-convex insertion structure 6 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 6. The first concave-convex insertion structure 6 includes a cooperating first protrusion 61 and a first groove 62. One of the directional component 3 and the handle body 1 has a first protrusion 61, and the other has a first groove 62. At least one of the first protrusions 61 and the first grooves 62 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 61 and the first groove 62 is not specifically limited. The first protrusion 61 can be a trapezoidal tooth or a circular arc tooth, etc., and the first groove 62 can be a trapezoidal groove or a circular arc groove, etc., respectively. For example, the directional component 3 may be provided with a first protrusion 61, the first protrusion 61 having a guide surface, and the front end of the handle body 1 having a plurality of first grooves 62 evenly distributed along the circumference. In this way, no matter which circumferential position the directional component 3 rotates to, the first protrusion 61 can move axially with the directional component 3 and smoothly embed into the corresponding first groove 62, thereby locking the directional component 3 and the handle body 1 circumferentially.

[0059] Of course, in order to achieve "when the adjusting component 3 is in the circumferential locking 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 6 can also be used. For example, a separable key and multiple key slots can also be used.

[0060] 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.

[0061] In the embodiments of this utility model, please refer to Figure 2 The directional component 3 includes:

[0062] The second operating sleeve 31 is movably fitted onto the outer periphery of the handle body 1; and

[0063] The transmission sleeve 32 is fixedly disposed inside the second operating sleeve 31, and the transmission sleeve 32 is circumferentially fixed to the mounting assembly 2;

[0064] The second 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.

[0065] Specifically, the directional adjustment component 3 consists of a second operating sleeve 31 and a transmission sleeve 32 sleeved together. The transmission sleeve 32 moves synchronously back and forth along the axial direction of the handle body 1, following the second operating sleeve 31, thereby achieving the insertion and locking or separation and unlocking of the transmission sleeve 32 and the end of the handle body 1. That is, when the direction of the tool needs to be adjusted, the user can slide the second operating sleeve 31 to the left, which will drive the transmission sleeve 32 to move synchronously to the left, thereby disengaging it from the handle body 1. At this time, the rotation of the transmission sleeve 32 and the second operating sleeve 31 can drive the mounting component 2 to rotate synchronously. When the direction of the tool needs to be fixed, the user can slide the second operating sleeve 31 to the right, which will drive the transmission sleeve 32 to move synchronously to the right, thereby inserting it into the handle body 1 to achieve locking. 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.

[0066] Among them, "the transmission sleeve 32 is relatively fixed inside the second operating sleeve 31", that is, the transmission sleeve 32 is circumferentially fixed and axially fixed relative to the second operating sleeve 31.

[0067] In the embodiments of this utility model, the elastic force of the elastic member 5 causes the transmission sleeve 32 to always abut against the stepped surface inside the second operating sleeve 31, so as to achieve relative fixation between the transmission sleeve 32 and the second operating sleeve 31 in the axial direction.

[0068] In the embodiments of this utility model, please refer to Figure 6 To achieve relative fixation between the transmission sleeve 32 and the operating sleeve 31, a second concave-convex insertion structure 7 is provided between them. The transmission sleeve 32 and the operating sleeve 31 are circumferentially fixed together by the second concave-convex insertion structure 7. Similarly, the second concave-convex insertion structure 7 includes a matching second protrusion 71 and a second groove 72. One of the transmission sleeve 32 and the operating sleeve 31 has a second protrusion 71, and the other has a second groove 72. For example, the outer wall of the adjacent end face of the transmission sleeve 32 has a second groove 72, and the operating sleeve 31 has a corresponding second protrusion 71. Of course, to achieve "circumferential relative fixation between the transmission sleeve 32 and the mounting component 2" and to satisfy "the adjusting component 3 is movably fitted onto 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 their mating surfaces.

[0069] This utility model also proposes a surgical power device 200, please refer to [link / reference]. Figure 7The surgical power device 200 includes a compatible medical cutting tool 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. It should be noted that the type of medical cutting tool is not specifically limited, for example, it can be a scalpel or the like. Furthermore, a surgical power device 200 can be equipped with one medical handle 100 or multiple medical handles 100, so that the operation of multiple medical handles 100 can be controlled by one surgical power device 200.

[0070] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
