Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a medical handle and a surgical power device. Background Art

[0002] In today's surgical field, minimally invasive surgical tools play a vital role in tissue removal surgery. For example, traditional planing tools are widely used in the cutting of soft tissues in parts such as the ear, nose and throat. During surgery, a handle is usually required, and the doctor controls the planing tool by manipulating the handle to complete the operation.

[0003] However, existing surgical knives have certain limitations in circumferential position adjustment. The circumferential adjustment of some surgical knives is achieved by rotating the entire handle, and the cable at the end of the handle needs to be dragged during the rotation process, which is inconvenient to operate; some surgical knives are axially adjusted by operating the circumferential adjustment mechanism on the handle. However, in actual operation, there is a situation where the knife is loosened due to accidental contact with the knife locking mechanism during the operation of the adjustment mechanism, affecting the safety of the operation. Summary of the invention

[0004] The main purpose of the present invention is to provide a medical handle and a surgical power device, which aims to solve the problem that the tool is easily accidentally hit by the tool locking structure during the adjustment process, causing the tool to loosen.

[0005] In order to achieve the above-mentioned object, the present invention provides a medical handle, which comprises:

[0006] handle body;

[0007] A mounting assembly is sleeved with the handle body and relatively fixed in axial position with the handle body, and has a tool mounting channel for mounting a tool;

[0008] a direction-adjusting assembly, which is movably sleeved on the outer circumference of the handle body and is circumferentially fixed to the mounting assembly; the movable position of the direction-adjusting assembly along the axial direction of the mounting assembly includes a circumferential locking position and a circumferential unlocking position; when the direction-adjusting assembly is in the circumferential locking position, the direction-adjusting assembly and the handle body are circumferentially locked; when the direction-adjusting assembly is in the circumferential unlocking position, the direction-adjusting assembly and the handle body are circumferentially unlocked, so that the mounting assembly can rotate circumferentially relative to the handle body along with the direction-adjusting assembly; and

[0009] The locking assembly comprises a first operating sleeve movably sleeved on the outer periphery of the mounting assembly, the first operating sleeve moves along the axial direction of the mounting assembly to lock or unlock the tool in the tool installation channel, and the movable position of the first operating sleeve along its own axial direction comprises a tool locking position and a tool unlocking position;

[0010] Wherein, when the direction adjustment assembly is in the circumferential unlocking position, the direction adjustment assembly has a tendency to press against the locking assembly toward the tool locking position so as to keep the locking assembly in the tool locking position.

[0011] In one embodiment, the medical handle further comprises an elastic member, and the elastic member is disposed between the direction adjustment component and the first operating sleeve, so that the first operating sleeve and the direction adjustment component are respectively maintained in the tool locking position and the circumferential locking position in a non-operating state;

[0012] When the first operating sleeve is in the tool unlocking position, the elastic member pushes the direction adjustment assembly to remain in the circumferential locking position.

[0013] In one embodiment, a mounting cavity is formed between the first operating sleeve and the mounting assembly, and the elastic member is disposed in the mounting cavity.

[0014] In one embodiment, the handle body is provided with a cavity, the mounting assembly is disposed in the cavity, and the mounting assembly has an extension portion extending forward from the cavity, the direction adjustment assembly is partially sleeved on the periphery of the extension portion, and the first operating sleeve is sleeved on the periphery of the extension portion.

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

[0016] In one embodiment, the mounting assembly includes a mounting sleeve, a side wall of the mounting sleeve is provided with a receiving groove, and the locking assembly also includes a locking member provided in the receiving groove, and the locking member can partially extend into or withdraw from the tool mounting channel to lock or unlock the tool in the tool mounting channel;

[0017] When the first operating sleeve is located at the tool unlocking position, the first operating sleeve avoids the path of the locking member exiting the tool installation passage to unlock the tool;

[0018] When the first operating sleeve is located at the tool locking position, the first operating sleeve blocks the path of the locking member exiting the tool installation passage 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 in the axial direction. When the first operating sleeve is located in the tool unlocking position, the position of the movable groove corresponds to the position of the accommodating groove so that the locking member can partially retreat into the movable groove. When the first operating sleeve is located in the tool locking position, the position of the blocking portion corresponds to the position of the accommodating groove.

[0020] In one embodiment, a first concave-convex plug-in structure is provided between the direction adjustment component and the handle body, and the direction adjustment component and the handle body can be plugged in or separated through the first concave-convex plug-in structure.

[0021] In some embodiments, the first concave-convex plug-in structure includes a matching first protrusion and a first groove, one of the direction adjustment component and the handle body is provided with the first protrusion, and the other is provided with the first groove, and at least one of the first protrusion and the first groove is distributed in plurality along the circumferential direction, so that the direction adjustment component can be locked at multiple circumferential positions of the handle body.

[0022] In one embodiment, the steering assembly comprises:

[0023] A second operating sleeve is movably sleeved on the outer circumference of the handle body; and

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

[0025] Wherein, the second operating sleeve can be operated to slide back and forth along the axial direction of the handle body to lock or unlock the connection between the transmission sleeve and the handle body.

[0026] To achieve the above-mentioned object, the present invention further proposes a surgical power device, which includes a matching medical handle and a medical knife, and the medical handle is the medical handle described in any of the above embodiments.

[0027] The technical solution of the present invention adopts the cooperation mechanism of the direction-adjusting component and the locking component, which realizes that while the direction-adjusting component adjusts the direction of the tool, it can also drive the locking component to lock the tool, which significantly improves the fixing strength of the tool. The circumferential degree of freedom of the mounting component is switched by the axial movement of the direction-adjusting component between the circumferential locking position and the circumferential unlocking position. When the direction-adjusting component slides to the circumferential locking position, the direction-adjusting component and the handle body are in a circumferential locking state, and the mounting component is also fixed together with the direction-adjusting component. At this time, the tool cannot rotate to adjust the direction; when the direction-adjusting component slides to the circumferential unlocking position, the direction-adjusting component and the handle body are in a circumferential unlocking state, and the direction-adjusting component and the mounting component can rotate synchronously relative to the circumference of the handle body, so that the mounting component drives the tool to adjust according to the target angle. In addition, the locking or unlocking of the tool is achieved by the reciprocating movement of the first operating sleeve in the locking assembly in the axial direction of the mounting assembly; when the direction adjustment assembly is in the circumferential unlocking position, the direction adjustment assembly has a tendency to press the locking assembly toward the tool locking position, so that the locking assembly remains in the tool locking position, ensuring that the tool is always stable during the direction adjustment process, eliminating the risk of the tool loosening or even falling off due to rotation operation, and improving the safety of operation.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] Existing surgical knives have certain limitations in circumferential position adjustment. The circumferential adjustment of some surgical knives is achieved by rotating the entire handle, and the cable at the end of the handle needs to be dragged during the rotation process, which is inconvenient to operate; some surgical knives are axially adjusted by operating the circumferential adjustment mechanism on the handle. However, in actual operation, there is a situation where the knife is loosened due to accidental contact with the knife locking mechanism during the operation of the adjustment mechanism, affecting the safety of the operation.

[0044] The invention provides a medical handle.

[0045] See also Figure 1 and Figure 2 In one embodiment of the present invention, the medical handle 100 comprises:

[0046] Handle body 1;

[0047] The mounting assembly 2 is sleeved with the handle body 1 and relatively fixed in axial position with the handle body 1, and has a tool mounting channel for mounting a tool;

[0048] The direction-adjusting component 3 is movably sleeved on the outer circumference of the handle body 1 and is circumferentially fixed to the mounting component 2. The movable position of the direction-adjusting component 3 along the axial direction of the mounting component 2 includes a circumferential locking position and a circumferential unlocking position. When the direction-adjusting component 3 is in the circumferential locking position, the direction-adjusting component 3 and the handle body 1 are circumferentially locked. When the direction-adjusting component 3 is in the circumferential unlocking position, the direction-adjusting component 3 and the handle body 1 are circumferentially unlocked, so that the mounting component 2 can rotate circumferentially relative to the handle body 1 along with the direction-adjusting component 3; and

[0049] The locking assembly 4 includes a first operating sleeve 41 that can be movably mounted 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 position of the first operating sleeve 41 along its own axial direction includes a tool locking position and a tool unlocking position.

[0050] The technical solution of the present invention adopts the cooperation mechanism of the direction adjustment component 3 and the locking component 4, which realizes the effect that while the direction adjustment component 3 adjusts the direction of the tool, the locking component 4 can also be driven to lock the tool. The circumferential degree of freedom of the mounting component 2 is switched by the axial movement of the direction adjustment component 3 between the circumferential locking position and the circumferential unlocking position. When the direction adjustment component 3 slides to the circumferential locking position, the direction adjustment component 3 and the handle body 1 are in a circumferential locking state, and the mounting component 2 is also fixed together with the direction adjustment component 3. At this time, the tool cannot rotate to adjust the direction; when the direction adjustment component 3 slides to the circumferential unlocking position, the direction adjustment component 3 and the handle body 1 are in a circumferential unlocking state, and the direction adjustment 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. In addition, the locking or unlocking of the tool is achieved through the axial reciprocating motion of the first operating sleeve 41 in the locking assembly 4 in the mounting assembly 2; when the direction adjustment assembly 3 is in the circumferential unlocking position, the direction adjustment assembly 3 has a tendency to press the locking assembly 4 toward the tool locking position, so that the locking assembly 4 remains in the tool locking position, ensuring that the tool is always stable during the direction adjustment process, eliminating the risk of the tool loosening or even falling off due to the rotation operation, and improving the safety of the operation.

[0051] Optionally, the direction adjustment component 3 is integrated with an angle scale ring, which is conducive to more accurate adjustment of the circumferential angle of the tool, and is particularly suitable for delicate surgical scenarios such as neurosurgery and otolaryngology.

[0052] In the embodiments of the present invention, please refer to Figure 1 and Figure 2The medical handle 100 also includes an elastic member 5, which is arranged between the direction adjustment component 3 and the first operating sleeve 41, so that the first operating sleeve 41 and the direction adjustment component 3 are respectively kept in the tool locking position and the circumferential locking position in the non-operating state; when the first operating sleeve 41 is in the tool unlocking position, the elastic member 5 pushes the direction adjustment component 3 to keep it in the circumferential locking position. In the present embodiment, the elastic member 5 can be a cylindrical spring, and the two ends of the spring respectively abut against the adjustment component 3 and the first operating sleeve 41. When the user does not perform any operation, due to the elastic tension at both ends of the spring, the elastic force at one end of the spring makes the end face of the adjustment component 3 away from the first operating sleeve 41 always keep in contact with the end face of the handle body 1, and the elastic force at the other end of the spring makes the first operating sleeve 41 have a tendency to move away from the adjustment component 3 and always remain in the tool locking position. When the user needs to disassemble the tool, the first operating sleeve 41 can be slid to the right to compress the elastic member 5 to overcome the elastic force of the elasticity and convert the first operating sleeve 41 from the tool locking position to the tool unlocking position.

[0053] In the embodiments of the present invention, please refer to Figure 1 A mounting cavity is formed between the first operating sleeve 41 and the mounting assembly 2, and the elastic member 5 is arranged in the mounting cavity. In this solution, the first operating sleeve 41 and the mounting assembly 2 are arranged in an axially spaced manner to reserve a mounting space for the elastic member 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 mounting assembly 2 to place the elastic member 5 in the annular hole.

[0054] In the embodiments of the present invention, please refer to Figure 2 The handle body 1 is provided with a cavity, the mounting assembly 2 is provided in the cavity, and the mounting assembly 2 has an extension portion extending forward from the cavity, the direction adjustment assembly 3 is partially sleeved on the outer periphery of the extension portion, and the first operating sleeve 41 is sleeved on the outer periphery of the extension portion.

[0055] In the embodiments of the present invention, please refer to Figures 1 to 3 The locking assembly 4 also includes a limit member 42, which is arranged on the outer periphery of the extension part and is axially fixed relative to the mounting assembly 2. The limit member 42 is arranged on the side of the first operating sleeve 41 axially away from the adjustment assembly 3, so that the first operating sleeve 41 is in abutment with the limit member 42 when it is in the tool locking position. The limit member 42 can be an annular structure, which can be well sleeved on the outer periphery of the extension part. The limit member 42 is arranged on the side of the first operating sleeve 41 axially away from the adjustment assembly 3, so that when the tool needs to be locked, the adjustment assembly 3 can press the first operating sleeve 41 against the limit member 42, so that the first operating sleeve 41 is kept in the locked position, which is conducive to ensuring that the tool is always kept in a stable locking state during the entire operation, reducing the risk of the tool loosening or falling off.

[0056] In the embodiments of the present invention, please refer to Figure 4 The mounting assembly 2 includes a mounting sleeve 21, which is in the shape of a hollow cylinder. A receiving groove 211 is provided on the side wall of the mounting sleeve 21; the locking assembly 4 also includes a locking member 43 provided in the receiving groove 211, and the locking member 43 can partially extend into or withdraw from the tool installation channel to lock or unlock the tool in the tool installation channel; when the first operating sleeve 41 is located in the tool unlocking position, it can avoid the path of the locking member 43 withdrawing from the tool installation channel, so that the locking member 43 can smoothly withdraw from the tool installation channel partially to achieve the unlocking of the tool; when the first operating sleeve 41 is located in the tool locking position, the first operating sleeve 41 blocks the path of the locking member 43 withdrawing from the tool installation channel, forming a reliable physical barrier. It is worth mentioning that a locking groove (not shown) for the locking member 43 to fit in and be embedded is provided on the tool adapted in the tool installation channel (not shown in the figure), so that the locking member 43 locks the tool by entering or withdrawing from the locking groove. This structure realizes the rapid disassembly and assembly of the tool. It should be noted that, please refer to Figure 4 The mounting assembly 2 may further include a protective sleeve 22, which is sleeved on the outer periphery of the mounting sleeve 21 and is sleeved in the cavity. The protective sleeve 22 is provided with a flange 221, and the mounting sleeve 21 is provided with a limiting shoulder 212, and the flange 221 is respectively against the shift step 12 and the limiting shoulder 212. Specifically, a flange 221 is provided at one end of the protective sleeve 22 close to the shift step 12. This structure is conducive to preventing the mounting sleeve 21 and the handle body 1 from being bonded together due to rust due to the provision of the protective sleeve 22. Optionally, the protective sleeve 22 may be made of PEEK material.

[0057] In the embodiments of the present invention, please refer to Figure 1The inner wall of the first operating sleeve 41 is provided with a movable groove 411 and a blocking portion 412 adjacent to each other in the axial direction. When the first operating sleeve 41 is located 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 partially retreat into the movable groove 411. When the first operating sleeve 41 is located in the tool locking position, the position of the blocking portion 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 ensure that the switching between the tool unlocking position and the tool locking position can be achieved through 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 blocking portion 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. 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 first operating sleeve 41 is fixed and cannot move, and the locking member 43 extends into the tool installation channel and can cooperate with the locking groove on the tool to lock the tool (not shown); when the tool needs to be disassembled, the first operating sleeve 41 can be slid to the right, compressing the elastic member 5 to overcome the elastic force of the elastic member 5, so that the movable groove 411 is connected with the receiving groove 211, and the locking member 43 can move in the space between the movable groove 411 and the receiving groove 211. At this time, by pulling out the tool, the locking member 43 can be pushed to move toward the movable groove 411 to withdraw from the tool installation channel, so that the tool can be inserted or pulled out of the tool installation channel. In this embodiment, the locking member 43 can be a structure that is easy to roll, such as a ball.

[0058] In the embodiments of the present invention, please refer to Figure 2 and Figure 5A first concave-convex plug-in structure 6 is provided between the direction adjustment component 3 and the handle body 1, and the direction adjustment component 3 and the handle body 1 can be plugged or separated through the first concave-convex plug-in structure 6. The first concave-convex plug-in structure 6 includes a first protrusion 61 and a first groove 62 that match each other. One of the direction adjustment component 3 and the handle body 1 is provided with a first protrusion 61, and the other is provided with a first groove 62, and at least one of the first protrusion 61 and the first groove 62 is distributed in multiple intervals along the circumferential direction, so that the direction adjustment component 3 can be locked at multiple circumferential positions of the handle body 1. In addition, the structures of the first protrusion 61 and the first groove 62 are 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 an arc groove, etc. For example, the direction adjusting component 3 may be provided with a first protrusion 61 having a guide surface, and the front end of the handle body 1 may be evenly distributed with a plurality of first grooves 62 along the circumferential direction. In this way, no matter to which circumferential position the direction adjusting component 3 rotates, the first protrusion 61 may move axially with the direction adjusting component 3 and be smoothly embedded in the first groove 62 at the corresponding position, thereby circumferentially locking the direction adjusting component 3 and the handle body 1.

[0059] Of course, in order to realize "when the direction adjustment component 3 is in the circumferential locking position, the direction adjustment component 3 and the handle body 1 are circumferentially locked, and when the direction adjustment component 3 is in the unlocking position, the direction adjustment component 3 and the handle body 1 are circumferentially unlocked", other forms of the first concave-convex plug-in structure 6 may also be adopted, for example, a detachable key and multiple key slots may also be adopted.

[0060] In some embodiments, the steering assembly 3 is an integrated structure, consisting of a single part; of course, the steering assembly 3 may also be a combination of multiple parts.

[0061] In the embodiments of the present invention, please refer to Figure 2 , the steering component 3 includes:

[0062] The second operating sleeve 31 is movably sleeved on the outer circumference of the handle body 1; and

[0063] The transmission sleeve 32 is relatively 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 operated to slide back and forth along the axial direction of the handle body 1 to lock or unlock the transmission sleeve 32 and the handle body 1 .

[0065] Specifically, the direction adjustment component 3 is composed of a second operating sleeve 31 and a transmission sleeve 32, and the transmission sleeve 32 follows the second operating sleeve 31 to perform synchronous reciprocating motion in the axial direction of the handle body 1, thereby realizing the plug-in locking or separation 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 to the left synchronously, thereby separating from the handle body 1 and achieving separation. At this time, with the rotation of the transmission sleeve 32 and the second operating sleeve 31, the installation component 2 can be driven 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, driving the transmission sleeve 32 to move to the right synchronously, thereby plugging and fixing with the handle body 1 to achieve locking. At this time, the transmission sleeve 32 is fixed at the end of the handle body 1, and the installation component 2 is also fixed accordingly, and the tool cannot be adjusted.

[0066] Here, “the transmission sleeve 32 is relatively fixedly disposed inside the second operating sleeve 31 ”, that is, the transmission sleeve 32 is circumferentially and axially fixed relative to the second operating sleeve 31 .

[0067] In the embodiment of the present invention, the elastic force of the elastic member 5 enables the transmission sleeve 32 to always abut against the step surface inside the second operating sleeve 31 , so as to achieve relative fixation of the transmission sleeve 32 and the second operating sleeve 31 in the axial direction.

[0068] In the embodiments of the present invention, please refer to Figure 6 In order to achieve the relative fixation between the transmission sleeve 32 and the operating sleeve 31, a second concave-convex plug-in structure 7 is provided between the transmission sleeve 32 and the operating sleeve 31, and the transmission sleeve 32 and the operating sleeve 31 are relatively fixed in the circumferential direction through the second concave-convex plug-in structure 7. Similarly, the second concave-convex plug-in structure 7 includes a second protrusion 71 and a second groove 72 that match each other. One of the transmission sleeve 32 and the operating sleeve 31 is provided with the second protrusion 71, and the other is provided with the second groove 72. For example, the outer wall of the adjacent end surface of the transmission sleeve 32 is provided with the second groove 72, and the operating sleeve 31 is correspondingly provided with the second protrusion 71. Of course, in order to achieve "the transmission sleeve 32 and the mounting assembly 2 are relatively fixed in the circumferential direction" and meet the "direction adjustment assembly 3, which can be movably sleeved on the outer periphery of the handle body 1", other methods can also be adopted. For example, the transmission sleeve 32 and the mounting assembly 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 surfaces of the two.

[0069] The present invention also provides a surgical power device 200, see Figure 7The surgical power device 200 includes a matching medical knife and a medical handle 100. The specific structure of the medical handle 100 refers to the above embodiment. Since the surgical power device 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. It should be noted that there is no specific limitation on the type of medical knife, for example, it can be a planer knife, etc. In addition, one medical handle 100 can be installed in a surgical power device 200, or multiple medical handles 100 can be installed, so that the operation of multiple medical handles 100 can be controlled by one surgical power device 200.

[0070] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
