Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a medical powered mobile phone and surgical instruments. 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] In traditional power units, the blade has to pass through the recognition component before connecting to the motor's output shaft. This results in a longer powered handpiece, which in turn increases its weight. Doctors may experience hand fatigue after prolonged use, affecting subsequent 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 powered handpiece and surgical instrument to solve the problem that the existing powered handpieces are long and heavy, and that prolonged use affects the doctor's operation.

[0005] To achieve the above and other related objectives, in one aspect, this utility model provides a medical powered handpiece, which is adapted to a cutting tool, and the medical powered handpiece includes:

[0006] The handle body has a motor mounting cavity for mounting a motor and a tool mounting cavity for a tool to pass through.

[0007] An identification component for identifying the cutting tool is installed between the motor mounting cavity and the cutting tool mounting cavity, and an inner cavity is provided inside the identification component;

[0008] An adapter assembly is disposed within the inner cavity and is used to connect the power input end of the cutting tool and the power output end of the motor.

[0009] The tool mounting cavity, the inner cavity, and the motor mounting cavity are arranged sequentially along the axial direction of the motor output shaft.

[0010] Furthermore, the adapter assembly includes an adapter member, which has a first torque transmission part for connecting with a cutting tool and a second torque transmission part for connecting with the output end of a motor.

[0011] Furthermore, the end of the first torque transmission part is provided with a first torque transmission groove extending along its own axial direction, and the end of the second torque transmission part is provided with a second torque transmission groove extending along its own axial direction.

[0012] Furthermore, a guide section for guiding is provided at the end of the first torque transmission groove away from the second torque transmission groove, and the groove width of the guide section gradually decreases from the end away from the second torque transmission groove toward the end near the second connecting hole.

[0013] Furthermore, the adapter assembly also includes a sleeve, the motor has an output spindle, the output end protrudes from the end of the output spindle, the sleeve is fitted over the output spindle, and the adapter is fitted inside the sleeve.

[0014] Furthermore, the inner wall of the sleeve is provided with a first axial limiting part and a second axial limiting part. The adapter is axially disposed between the first axial limiting part and the second axial limiting part. The sleeve is provided with a clamping spring. One end of the clamping spring abuts against the adapter and the other end abuts against one of the limiting parts of the first axial limiting part and the second axial limiting part, so that the other end of the adapter abuts against the other limiting part of the first axial limiting part and the second axial limiting part.

[0015] Furthermore, the identification component includes a support sleeve and an identification coil, the identification coil being wound around the support sleeve.

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.

[0028] In order to describe this utility model in detail, the medical powered mobile phone and surgical instruments provided by this utility model will be specifically described below.

[0029] like Figure 1As shown, this utility model provides a medical powered handpiece, wherein the medical powered handpiece is adapted to a cutting tool, and the cutting tool is installed on the medical powered handpiece to form a surgical instrument.

[0030] The medical power handpiece includes a handle body 3, an identification component 4, and an adapter component 6. The handle body 3 has a motor mounting cavity for mounting a motor and a tool mounting cavity 31 for a tool to pass through.

[0031] like Figure 1 As shown, the handle body 3 includes a handle housing and components connected to the handle housing.

[0032] The identification component 4 is installed between the motor mounting cavity and the tool mounting cavity 31, such as Figure 1 As shown, the right side of the identification component 4 is the motor mounting cavity, and the left side is the tool mounting cavity 31. The identification component 4 is used to identify tool information.

[0033] The identification component 4 has an internal cavity 45, and the adapter component 6 is disposed inside the internal cavity 45. The adapter component 6 rotates relative to the internal cavity 45. The motor drives the adapter component 6 to rotate, and the adapter component 6 drives the cutting tool to move, thereby realizing the rotation, swing and other operations of the cutting tool.

[0034] One end of the adapter component 6 is connected to the power input end of the cutting tool, and the other end is connected to the power output end of the motor. In order to shorten the length of the medical power handpiece, the cutting tool mounting cavity 31, the inner cavity 45, and the motor mounting cavity are arranged sequentially along the axial direction of the motor output shaft. That is, the inner cavity 45 is located in the middle of the cutting tool mounting cavity 31 and the motor mounting cavity, and the cutting tool does not penetrate the identification component 4.

[0035] Figure 1 In the example, the cutting tool includes a tool holder 1 and a shank 2 rotatably mounted within the tool holder 1 along its own axis. The tool holder 1 is detachably mounted in a tool mounting cavity 31. The cutting tool is inserted into the tool mounting cavity 31 and connected to the adapter assembly 6. The shank 2 rotates as the adapter assembly 6 rotates. The tool holder 1 is located in front of the identification assembly 4, and an electronic tag 5 is installed inside the tool holder 1. The identification assembly 4 obtains information about the cutting tool by identifying the electronic tag 5. In actual implementation, the cutting tool can also adopt other structures. For example, the cutting tool can also only include a shank (not shown in the figure), with a shank support component inside the handle body, and a tool mounting cavity 31 set inside the shank support component. In this case, the electronic tag is located at the rear end of the shank, corresponding to the position of the identification assembly.

[0036] In some embodiments, the adapter assembly 6 includes an adapter 60, which includes a first torque-transmitting part 61 and a second torque-transmitting part 62. The first torque-transmitting part 61 and the second torque-transmitting part 62 are rigidly fixedly connected, and the first torque-transmitting part 61 cannot rotate relative to the second torque-transmitting part 62, thereby realizing torque transmission. The first torque-transmitting part 61 is connected to the cutting tool and drives the cutting tool to rotate, while the second torque-transmitting part 62 is connected to the power output end of the motor. The first torque-transmitting part 61 and the second torque-transmitting part 62 are distributed at both ends of the adapter 60 along its own axial direction.

[0037] The output power of the motor is transmitted to the tool holder 2 after passing through the second torque transmission part 62 and the first torque transmission part 61, which drives the tool holder 2 to move.

[0038] In some embodiments, a first torque transmission groove 63 is provided in the first torque transmission section 61, and a torque transmission structure matching the first torque transmission groove 63 is provided on the corresponding cutting tool. The extension direction of the first torque transmission groove 63 is the length direction of the first torque transmission section 61. A second torque transmission groove 64 is provided in the second torque transmission section 62, and the extension direction of the second torque transmission groove 64 is the length direction of the second torque transmission section 62. The power output end of the motor enters the second torque transmission groove 64 and connects to the second torque transmission section 62. Of course, the second torque transmission section 62 can also adopt other methods. For example, the second torque transmission section 62 and the motor can be connected by splines, parallel keys, etc., as long as torque transmission can be achieved.

[0039] In some embodiments, the first torque transmission groove 63 on the first torque transmission part 61 and the torque transmission structure on the tool can be interchanged, that is, the first torque transmission groove 63 is provided on the tool, while the torque transmission structure is provided on the first adapter. Of course, the second torque transmission groove 64 on the first torque transmission part 61 and the torque transmission structure on the tool can also be interchanged.

[0040] Optionally, to facilitate insertion of the tool into the first torque transmission groove 63, a guide section 65 is provided at the end of the first torque transmission groove 63 away from the second torque transmission groove 64 for guiding. Specifically, the guide section 65 gradually decreases in width from the end away from the second torque transmission groove 64 toward the end near the second connecting hole. The guide section 65 is flared from left to right, and the width of the groove is the width of the groove extending radially along the first torque transmission part 61. The left side of the guide section 65 penetrates the outer wall of the adapter 60, or it may not penetrate the outer wall of the adapter 60. The width of the guide section 65 is larger on the left and smaller on the right, so that the tool holder 2 can be quickly inserted during insertion.

[0041] In some embodiments, the adapter assembly 6 further includes a sleeve 66 installed outside the adapter 60, with the adapter 60 fitted inside the sleeve 66, and the adapter 60 positioned by the sleeve 66; the motor has an output spindle 7, with the power output end of the motor protruding from the end of the output spindle 7, i.e., the left side of the power output end extends beyond the output spindle 7, thereby facilitating connection with the second torque transmission part 62. The sleeve 66 is fitted outside the output spindle 7, and the adapter 60 is fitted inside the sleeve 66, with the sleeve 66 supporting and positioning the adapter 60, making the adapter 60 coaxial with the output spindle 7.

[0042] Among them, sleeve 66 can rotate synchronously with output spindle 7, see [reference] Figure 1 A bearing is provided on the outside of the sleeve 66. The bearing has an outer ring and an inner ring. The outer ring is fixedly installed in the handle body, and the inner ring is fitted on the outside of the sleeve 66. In this way, the sleeve 66 can rotate synchronously with the output spindle 7.

[0043] Optionally, the inner wall of the sleeve 66 is provided with a first axial limiting portion 67 and a second axial limiting portion 68, which are respectively disposed at both ends of the sleeve 66 in the circumferential direction. An adapter 60 is axially disposed between the first axial limiting portion 67 and the second axial limiting portion 68. A retaining spring 69 is provided inside the sleeve 66. One end of the retaining spring 69 abuts against the adapter 60, and the other end abuts against one of the limiting portions of the first axial limiting portion 67 and the second axial limiting portion 68, so that the other end of the adapter 60 abuts against the other limiting portion of the first axial limiting portion and the second axial limiting portion 68. The retaining spring 69 holds the adapter 60 against the tool. In this embodiment, the retaining spring 69 is located between the second adapter 60 and the output spindle 7. Alternatively, the retaining spring 69 can be installed between the first torque transmission portion 61 and the tool holder 2.

[0044] The first axial limiting part 67 and the second axial limiting part 68 can be a protruding ring or a protruding block with only partial protrusion, as long as they can limit the clamping spring 69.

[0045] In some embodiments, the identification component 4 includes a support sleeve 41 and an identification coil, with the identification coil wound around the support sleeve 41. A wire-blocking portion 43 is provided at the front of the support sleeve 41, and an axial positioning protrusion 42 is provided at the rear. A spiral groove 44 is provided between the wire-blocking portion 43 and the axial positioning protrusion 42, and the spiral groove 44 extends along the axial direction of the support sleeve 41 to allow the identification coil to be wound.

[0046] On the other hand, this utility model also provides a surgical instrument, including the above-mentioned medical power handpiece and a knife adapted to the above-mentioned medical power handle. The knife passes through the knife mounting cavity 31 and is connected to the adapter component 6. The knife is provided with an electronic tag 5 adapted to the identification component 4.

[0047] Optionally, the cutting tool includes a tool holder 1 and a tool shank 2 rotatably mounted within the tool holder 1 along its own axis. The tool holder 1 is detachably mounted within the cutting tool mounting cavity 31 and located in front of the identification component 4. An electronic tag 5 is installed within the tool holder 1, and the identification component 4 is used to identify the electronic tag 5. In this structure, the electronic tag 5 is located within the tool holder 1. Since the tool holder 1 is relatively fixed within the cutting tool mounting cavity 31 and does not rotate with the tool shank 2, it helps to eliminate the risk of the electronic tag 5 falling off due to rotation.

[0048] Optionally, the rear end of the tool holder 1 is opposite to the front end of the recognition component 4, and a mounting groove is provided on the rear end face of the tool holder 1, in which the electronic tag 5 is installed. In this structure, the electronic tag 5 is adjacent to the end face of the recognition component 4, resulting in good recognition performance.

[0049] 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.
