Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a medical power handle and surgical power device with a knife recognition function. Background Technology

[0002] Surgical power devices are often used in some minimally invasive surgeries to manipulate bone or soft tissue. A surgical power device consists of a blade and a power handle. The blade is mounted on the power handle and connected to it. The power handle provides power to drive the blade to perform actions such as rotation and oscillation to act on the tissue and perform the surgical procedure.

[0003] Traditional surgical power devices with blade recognition functions place electronic tags on the blade holder and place the recognition component inside the handle on the outside of the blade holder, corresponding to the location of the recognition tag. In this way, the electronic tag does not rotate with the blade rod inside the blade holder. However, this method of placing the recognition tag on the outside of the blade results in a larger handle diameter, which is inconvenient for doctors to hold and perform surgical operations. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a medical power handle and surgical power device with a blade recognition function, so as to solve the problem that the large size of the existing surgical power device makes it inconvenient to hold.

[0011] An axial positioning protrusion is used to axially position the bracket within the handle body. The axial positioning protrusion protrudes from the outer wall of the support sleeve body and is located behind the identification coil.

[0012] Furthermore, the axial positioning protrusion is an annular protrusion, and a threading channel is provided on the annular protrusion.

[0013] Furthermore, the support sleeve body is coaxially sleeved with the handle body, and a positioning structure is provided between the axial positioning protrusion and the handle body to restrict the circumferential rotation of the bracket.

[0014] Furthermore, the support includes:

[0015] The identification coil is wound around the outside of the support sleeve body;

[0016] The wire-blocking part is provided on the outer wall of the support sleeve body and blocks the front of the identification coil.

[0017] Furthermore, the line-blocking portion is located at the front end of the support sleeve body.

[0018] Furthermore, a through hole is provided along the circumferential direction on the wire-blocking part, and the through hole is used for the identification coil to pass through and limit the identification coil.

[0019] Furthermore, the support sleeve body is provided with a winding groove, which is a spiral groove provided on the outer wall of the support sleeve body, and the spiral groove extends along the axial direction of the support sleeve body for the identification coil to be wound.

[0029] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0030] In order to describe this utility model in detail, the following is a specific description of a medical power handle and surgical power device with a knife recognition function provided by this utility model.

[0031] This utility model provides a medical power handle with a knife identification function, wherein the knife is connected to the medical power handle, and such... Figure 1As shown, the cutting tool consists of two parts: a blade holder 1 and a blade shank 2. The blade shank 2, as the core component for surgical operations, can rotate at high speed along its own axis, allowing the blade head connected to it to act on the target tissue using methods such as grinding, planing, or milling. The blade shank 2 passes through the blade holder 1 and is rotatably connected to it, enabling it to rotate relative to the blade holder 1 along its own axis. A motor is also installed inside the medical power handle; the blade shank 2 rotates under the motor's drive after being connected to it. An electronic tag 5 is installed inside the blade holder 1.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the medical power handle includes a handle body 3 and an identification component 4. The front end of the handle body 3 is provided with a knife holder mounting channel 31 for inserting the knife holder 1 axially. After the knife holder 1 is inserted into the knife holder mounting channel 31 of the handle body 3, it can be locked in the knife holder mounting channel 31 by the handle body 3, so that there will be no circumferential rotation or axial movement between the knife holder 1 and the handle body 3.

[0033] It should be noted that the tool locked in the tool holder mounting channel 31 of the handle body 3 can be achieved by the tool holder locking structure provided in the handle body 3, and the tool holder locking structure can be considered as part of the handle body 3. Figure 2 In this design, the tool holder 1 is provided with a locking groove. The tool locking structure includes a mounting sleeve 32, an operating sleeve 33, and a locking ball 34. Part of the inner wall of the mounting sleeve 32 forms the tool holder mounting channel 31. The operating sleeve 33 is fitted over the mounting sleeve 32 and is operable to move along the axial direction. The mounting sleeve 32 has a locking ball 34 mounting position, and the locking ball 34 is located at the locking ball 34 mounting position. The inner wall of the operating sleeve 33 includes a first inner wall and a second inner wall connected together, and the diameter of the second inner wall is larger than that of the first inner wall. When the operating sleeve moves forward in the direction shown in the figure, causing the first inner wall to move to the periphery of the locking ball 34 mounting position, the locking ball 34 can enter the tool holder mounting channel 31 and partially embed into the locking groove of the tool holder, thereby locking the tool. When the operating sleeve moves backward in the direction shown in the figure, causing the second inner wall to move to the periphery of the locking mounting position, the locking ball 34 is pushed out of the tool holder mounting channel 31 by the tool, unlocking the tool holder. Of course, locking and unlocking of the tool holder can also be achieved by other tool holder locking structures, as long as locking and unlocking of the tool holder can be achieved. For example, an operating sleeve 33 can be set outside the elastic clamping member. The internal structure of the elastic clamping member is the tool holder mounting channel 31. The axial movement of the operating sleeve 33 causes the elastic wall of the elastic clamping member to deform accordingly to clamp or release the tool holder, thereby achieving locking and unlocking of the tool holder.

[0034] In this utility model, "front" and "rear" are defined along the axial direction of the tool holder 2, with one end of the tool holder 2 being the front and the end of the handle body 3 where the motor is mounted being the rear. Figure 1As shown, the left side is the front, and the right side is the back.

[0035] The identification component 4 is installed inside the handle body 3 and is located behind the tool mounting channel. When the tool holder 1 is inserted into the tool holder mounting channel 31, the identification component 4 and the tool holder 1 are arranged adjacent to each other along the axial direction, such as... Figure 1 As shown, the blade holder 1 is located on the left, while the identification component 4 is located on the right side of the blade holder 1. In this way, the identification component 4 identifies the electronic tag 5 inside the blade holder 1 through the end face. The identification component 4 is no longer located outside the blade holder 1, which is beneficial to the diameter size of the medical power handle and makes it easier for doctors to hold and operate.

[0036] In some embodiments, the identification component 4 includes a bracket and an identification coil. The identification coil is wound around the bracket and is axially adjacent to the tool holder 1 inserted into the tool holder mounting channel 31. After the tool holder 1 is installed into the handle body 3, the tool holder 1 and the bracket are in close proximity along the axial direction, allowing the identification coil on the bracket to be wound as close as possible to the tool holder 1 along the axial direction, thus achieving proximity between the identification coil and the tool holder 1. This structure, because the identification coil and the electronic tag 5 are axially adjacent, helps ensure the reliability of tool identification.

[0037] The bracket includes a support sleeve body 41 and an axial positioning protrusion 42. In some embodiments, the support sleeve body 41 is hollow, and its outer wall can be cylindrical or elliptical, generally cylindrical. The identification coil is wound around the outer wall of the support sleeve body 41. The axial positioning protrusion 42 protrudes from the outer wall of the support sleeve body 41 and is used to axially position the bracket within the handle body 3. The axial positioning protrusion 42 cooperates with the axial positioning structure provided inside the handle body 3, preventing the support sleeve body 41 from moving left or right along the axial direction, thereby axially limiting the identification component 4.

[0038] For ease of understanding, see [link to relevant documentation]. Figure 2 The axial positioning structure includes a first limiting part 35 and a second limiting part 36, which respectively abut against the two ends of the axial positioning protrusion to restrict the movement of the axial positioning protrusion in the axial direction.

[0039] The axial positioning protrusion 42 is located behind the identification coil, thereby bringing the identification coil closer to the tool holder 1, which is beneficial for the identification coil to identify the electronic tag 5. The closer the identification coil is to the tool holder 1, the better the identification effect. At the same time, the axial positioning protrusion 42 located behind the identification coil can also limit the identification coil wound on the outer wall of the support sleeve body 41, preventing the identification coil from detaching from the support sleeve body 41 from the rear.

[0040] In some embodiments, the axial positioning protrusion 42 may be one or more protrusions arranged radially outward on the outer wall of the support sleeve body 41, or it may be an annular protrusion formed circumferentially on the outer side of the support sleeve body 41. If the axial positioning protrusion 42 is an annular protrusion, a wire passage 43 needs to be provided on the annular protrusion so that the wire of the identification coil can pass through the wire passage 43. Of course, if multiple spaced protrusions are provided on the outer side of the support sleeve body 41, then the interval between the protrusions forms the wire passage 43.

[0041] Optionally, the threading channel 43 can be a hole provided axially in the axial positioning protrusion 42, or a notch provided in the axial positioning protrusion 42.

[0042] In some embodiments, in order to keep the bracket stationary relative to the handle body 3, that is, to keep it stationary relative to the tool holder 1, so as to improve the reliability of tool identification, the support sleeve body 41 is coaxially sleeved with the handle body 3, and a positioning structure restricting the circumferential rotation of the bracket is provided between the axial positioning protrusion 42 and the handle body 41.

[0043] Optionally, the positioning structure includes at least two positioning holes 44 provided on the axial positioning protrusion 42, and a pin hole provided on the handle body. The positioning pin passes through the positioning hole 44 and connects with the pin hole, thereby fixing the bracket circumferentially and preventing the bracket from rotating circumferentially relative to the handle body 41. It is worth mentioning that the positioning structure can also adopt other structures. For example, the positioning protrusion can be integrated on one of the handle body 3 and the axial positioning protrusion 42, and a positioning hole that mates with the positioning protrusion can be provided on the other of the handle body 3 and the axial positioning protrusion 42.

[0044] In order to ensure the coaxiality of the bracket and the handle body 3, such as Figure 4 As shown, the axial positioning protrusion 42 is not located at the rear end of the support sleeve body 41, thus there is a certain distance between the axial positioning protrusion 42 and the rear end of the support sleeve body 41. Figure 1 and Figure 2 As shown, the support sleeve body 41 at the rear of the axial positioning protrusion 42 is fitted inside the other components inside the handle body 3. The other components are, for example, the sleeve for mounting the motor behind the support sleeve body 41, thereby ensuring the coaxiality of the support sleeve body 41 and the handle body 3.

[0045] In some embodiments, a wire-blocking portion 45 is provided on the outer wall of the support sleeve body 41. The wire-blocking portion 45 is located in front of the support sleeve body 41 and is mainly used to prevent the identification coil from slipping off the front of the support sleeve body 41 and detaching from the support sleeve body 41.

[0046] Optionally, to shorten the distance between the recognition coil and the tool holder 1 without affecting the recognition effect, the wire stop 45 is set at the front end of the support sleeve body 41, that is, the wire stop 45 is set on the end face of the support sleeve body 41 near the tool holder 1. The wire stop 45 can also be a protruding ring set on the support sleeve body 41. The diameter of the wire stop 45 is smaller than the diameter of the axial positioning protrusion 42, so that when the bracket is installed into the handle body 3, the wire stop 45 will not obstruct the assembly of the axial positioning protrusion 42 with the axial positioning structure inside the handle body 3.

[0047] In some embodiments, in order to prevent the distance between the identification coil and the electronic tag 5 from changing after the identification coil slides backward along the axial direction, a through hole is provided on the wire-blocking part 45. After the double-strand identification coil is wound around the support sleeve body 41, the rear end extends backward to connect to the positive and negative poles respectively, and the front end can be inserted into the through hole. The identification coil is limited by the through hole to prevent the identification coil from moving backward.

[0048] In some embodiments, to prevent the identification coil from swaying left and right during use, a winding groove 46 is provided on the support sleeve body 41, and the identification coil is located in the winding groove 46. The winding groove 46 can be a spiral groove provided on the outer wall of the support sleeve body 41, and the spiral groove extends along the axial direction of the support sleeve body 41, so that the identification coil can be spirally wound along the spiral groove.

[0049] The threading channel 43 is connected to the winding groove 46, which allows the identification coil to extend smoothly backward.

[0050] On the other hand, this utility model also provides a surgical power device, including any of the above-mentioned medical power handles with knife identification function and a knife adapted to the medical power handle. The knife includes a knife holder 1 and a knife bar 2 that is rotatably inserted in the knife holder 1 along its own axis. The knife holder 1 is provided with an electronic tag 5.

[0051] The tool holder 1 has an opening at its rear end, and the electronic tag 5 is placed inside the opening so that the electronic tag 5 is located at the rear end of the tool holder 1.

[0052] The electronic tag 5 inside the blade holder 1 is adjacent to the identification component 4 along the axial direction, which can be considered as using end face identification. The distance between the electronic tag 5 and the identification coil is close enough to make the identification effect good. Furthermore, since the identification component inside the medical power handle is not located on the periphery of the blade holder 1, it is beneficial to reduce the diameter of the medical power handle, making it easier for doctors to hold and operate.

[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
