[0002] In related technologies, during surgery, the electrically powered handpiece assembly includes an electrically powered handpiece and a sterile housing. The electrically powered handpiece is installed inside the sterile housing, and the working head (e.g., a vascular clamp cartridge) is installed inside the sterile housing. The working head is connected to the electrically powered handpiece via a drive mechanism, and the working head is controlled by the electrically powered handpiece. However, during surgery, if the electrically powered handpiece malfunctions and cannot drive the working head to perform surgical operations, it needs to be replaced. Since the electrically powered handpiece is not sterile, replacing it may contaminate the sterile housing, potentially contaminating the patient and harming their health. Furthermore, replacing the electrically powered handpiece during surgery prolongs the operation time and reduces surgical efficiency. Summary of the Invention

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following is for reference. Figures 1-5 This invention describes a sterile housing 100 according to an embodiment of the present invention. The sterile housing 100 and the electric handle 200 constitute an electric handle assembly 300. The electric handle 200 is a reusable, non-sterile instrument. The sterile housing 100 is used to mount the electric handle 200, which is installed inside the sterile housing 100. A working head is mounted on the sterile housing 100 and is connected to the electric handle 200 via a transmission connection. The working head is controlled by the electric handle 200. The working head can be a vascular clamp; this application uses a vascular clamp as an example for illustration.

[0046] like Figures 1-5 As shown, the sterile housing 100 according to an embodiment of the present invention includes: a housing body 10 and a manual drive shaft 20. The manual drive shaft 20 is a sterile component. An installation space 11 for mounting an electric handle 200 is formed within the housing body 10, and the electric handle 200 is mounted within the installation space 11. The manual drive shaft 20 is selectively connected to the electric handle 200 to drive the electric handle 200 to operate. That is, the manual drive shaft 20 can be connected to the electric handle 200, and the manual drive shaft 20 can also be disconnected from the electric handle 200. When the manual drive shaft 20 is connected to the electric handle 200 (either directly or indirectly), the manual drive shaft 20 can drive the electric handle 200 to operate.

[0047] The electric handle 200 may have a handle drive shaft (e.g., a motor output shaft) that is connected to the working head. The electric handle 200 has an operating hole 201, which can be located within the motor 202 of the electric handle 200. A transmission mechanism exists between the handle drive shaft and the motor 202. The manual drive shaft 20 has an operating end 23 near the mounting space 11, which is adapted to be inserted into the operating hole 201. The operating hole 201 has a polygonal cross-section, and the cross-sectional shape of the operating end 23 matches the cross-sectional shape of the operating hole 201. Before surgery, the electric handle 200 is installed in the mounting space 11 of the sterile housing 100, and the working head is installed in the sterile housing 100 and connected to the electric handle 200. When the electric handle 200 is functioning correctly and can drive the working head normally, the electric handle 200 electrically drives the handle drive shaft to drive the working head. When the electric handle 200 malfunctions and cannot drive the working head to work normally, and it is necessary to manually control the electric handle 200 to drive the working head, i.e., to manually drive the vascular clamp to perform clamp delivery or closure operations, the manual drive shaft 20 is connected to the electric handle 200. At this time, the operating end 23 is inserted into the operating hole 201, and then the handle drive shaft of the electric handle 200 is driven by the manual drive shaft 20 to drive the working head, thus achieving the purpose of manually operating the vascular clamp. This setting allows the electric handle 200 to drive the working head via the manual drive shaft 20, avoiding the need to replace the electric handle 200 during surgery, reducing the risk of contamination of the sterile shell 100, which is beneficial to the patient's health. Furthermore, since the electric handle 200 does not need to be replaced during surgery, it can shorten the operation time and improve surgical efficiency.

[0048] Therefore, by setting a manual drive shaft 20, when the electric handle 200 malfunctions and cannot drive the working head to perform surgical operations, the manual drive shaft 20 can be controlled to drive the electric handle 200 to drive the working head. This avoids the need to replace the electric handle 200 during surgery, reduces the risk of contamination of the sterile shell 100, is beneficial to the patient's health, and improves surgical efficiency. Furthermore, by setting the manual drive shaft 20 on the shell body 10, the manual drive shaft 20 can be integrated into the shell body 10, making it convenient for doctors to operate the manual drive shaft 20 without the need for separate placement, thus solving the problem of separate placement of the manual drive shaft 20.

[0049] In some embodiments of the present invention, the manual drive shaft 20 passes through the housing body 10 and extends into the mounting space 11. Specifically, the end of the manual drive shaft 20 near the mounting space 11 extends into the mounting space 11. The manual drive shaft 20 has a first position and a second position relative to the housing body 10. The manual drive shaft 20 selectively moves to the first position or the second position. When in the first position, the manual drive shaft 20 is connected to the electric handle 200 to drive the electric handle 200 to work, so that the electric handle 200 drives the working head to work. When in the second position, the manual drive shaft 20 is separated from the electric handle 200.

[0050] The electric handle 200 may have a handle drive shaft (e.g., a motor output shaft) that is connected to the working head. The electric handle 200 has an operation hole 201, which can be located within the motor 202 of the electric handle 200. The manual drive shaft 20 has an operation end 23 at its end near the mounting space 11. The operation end 23 is adapted to be inserted into the operation hole 201. The cross-section of the operation hole 201 is polygonal, and the cross-sectional shape of the operation end 23 matches the cross-sectional shape of the operation hole 201. Before surgery, the electric handle 200 is installed in the mounting space 11 of the sterile housing 100, and the working head is installed in the sterile housing 100 and connected to the electric handle 200. When the electric handle 200 is functioning correctly and can drive the working head normally, the manual drive shaft 20 is in a second position relative to the housing body 10, the operation end 23 is not inserted into the operation hole 201 of the electric handle 200, and the manual drive shaft 20 is separated from the electric handle 200. When the electric handle 200 malfunctions and cannot drive the working head to work normally, and it is necessary to manually control the electric handle 200 to drive the working head, i.e., to manually drive the vascular clamp to perform clamping or clamping operations, the manual drive shaft 20 is moved relative to the housing body 10 to the first position, so that the manual drive shaft 20 is connected to the electric handle 200. At this time, the operating end 23 is inserted into the operating hole 201, and then the handle drive shaft of the electric handle 200 is driven by the manual drive shaft 20 to drive the working head, so as to achieve the purpose of manually operating the vascular clamp. This setting allows the electric handle 200 to drive the working head through the manual drive shaft 20, which can avoid replacing the electric handle 200 during the operation, reduce the risk of contamination of the sterile housing 100, and benefit the patient's health. Furthermore, since the electric handle 200 does not need to be replaced during the operation, the operation time can be shortened and the efficiency of the operation can be improved.

[0051] Meanwhile, if the manual drive shaft 20 is set as a separate component, that is, the manual drive shaft 20 and the housing body 10 are separate parts, when using the manual drive shaft 20 to drive the electric handle 200 to drive the working head, the manual drive shaft 20 needs to pass through the sterile housing body 10 to reach the sterile electric handle 200. After the operation is completed, it detaches from the electric handle 200, and the manual drive shaft 20 becomes a contaminated object. The process of the manual drive shaft 20 detaching from the housing body 10 will pose a risk of contaminating the sterile housing body 10. In this application, by setting the manual drive shaft 20 in the housing body 10, the manual drive shaft 20 can be integrated into the housing body 10. The manual drive shaft 20 is part of the sterile housing 100 and is not separated from the housing body 10, which greatly reduces the risk of the manual drive shaft 20 contaminating the housing body 10. It also makes it easier for doctors to operate the manual drive shaft 20, which can further improve surgical efficiency. In addition, there is no need to store the manual drive shaft 20 separately, solving the problem of separate storage of the manual drive shaft 20.

[0052] In some embodiments of the present invention, the manual drive shaft 20 is adapted to move to a first position or a second position along the axial direction of the manual drive shaft 20. Wherein, for example... Figure 2 As shown, when it is not necessary for the manual drive shaft 20 to control the electric handle 200 to drive the working head, the manual drive shaft 20 is moved relative to the housing body 10 along its axial direction to the second position, thus separating the manual drive shaft 20 from the electric handle 200. When it is necessary for the manual drive shaft 20 to control the electric handle 200 to drive the working head, the manual drive shaft 20 is moved relative to the housing body 10 along its axial direction to the first position, thus connecting the manual drive shaft 20 to the electric handle 200. At this time, rotating the manual drive shaft 20 will control the electric handle 200 to drive the working head.

[0053] In some embodiments of the present invention, such as Figure 2 As shown, the housing body 10 has a mounting portion 12, which defines an assembly hole 13 communicating with the mounting space 11. A manual drive shaft 20 is mounted in the assembly hole 13 and is adapted to move along the axial direction of the assembly hole 13 to a first position or a second position. The manual drive shaft 20 extends along the axial direction of the assembly hole 13, and further, the central axis of the manual drive shaft 20 is collinear with the central axis of the assembly hole 13. The manual drive shaft 20 is adapted to move along the axial direction of the assembly hole 13 to the first position or the second position. During the movement of the manual drive shaft 20 along the axial direction of the assembly hole 13, the inner wall of the assembly hole 13 guides the manual drive shaft 20, ensuring that the manual drive shaft 20 moves along the axial direction of the assembly hole 13.

[0054] In some embodiments of the present invention, the sterile housing 100 may further include a damping plug (not shown in the figure), which is disposed within the mounting hole 13 and sleeved on the outside of the manual drive shaft 20. The damping plug may be a rubber plug or a plastic plug, and it serves a sealing function as well as increasing the friction between the damping plug and the manual drive shaft 20. The damping plug is installed between the manual drive shaft 20 and the inner wall of the mounting hole 13. It seals the gap between the manual drive shaft 20 and the mounting hole 13, increases the friction between them, prevents the manual drive shaft 20 from moving out of the mounting hole 13, and restricts the axial movement of the manual drive shaft 20 along the mounting hole 13.

[0055] In some embodiments of the present invention, such as Figure 2 As shown, a first stop wall 14 is provided on the inner sidewall of the assembly hole 13. The first stop wall 14 can extend circumferentially along the assembly hole 13. The first stop wall 14 is located near the end of the assembly hole 13 away from the installation space 11. Alternatively, it can be understood that the first stop wall 14 is located near the outer end of the assembly hole 13. A second stop wall 21 is provided on the outer sidewall of the manual drive shaft 20. The second stop wall 21 can extend circumferentially along the manual drive shaft 20. The second stop wall 21 is adapted to stop and limit the first stop wall 14. Furthermore, the first stop wall 14 defines a through hole, through which the manual drive shaft 20 passes. When the manual drive shaft 20 moves toward the second position along the axial direction of the mounting hole 13, it can also be understood that when the manual drive shaft 20 moves away from the mounting space 11 along the axial direction of the mounting hole 13, the second stop wall 21 and the first stop wall 14 stop and limit the movement, thus preventing the manual drive shaft 20 from moving out of the mounting hole 13 and preventing the manual drive shaft 20 from detaching from the housing body 10, thereby achieving the effect of integrating the manual drive shaft 20 into the housing body 10.

[0056] In some embodiments of the present invention, such as Figures 1-3As shown, the sterile housing 100 may further include a manual operation unit 30, which is disposed outside the housing body 10 and connected to a manual drive shaft 20. The manual operation unit 30 is used to drive the manual drive shaft 20 to move to a first position or a second position. Specifically, when the manual drive shaft 20 is needed to control the electric handle 200 to drive the working head, the operator controls the manual operation unit 30 to drive the manual drive shaft 20 from the second position to the first position, connecting the manual drive shaft 20 to the electric handle 200. At this time, the operating end 23 is inserted into the operating hole 201, and then the operator rotates the manual drive shaft 20 to drive the handle drive shaft of the electric handle 200 to drive the working head, achieving the effect of manually operating the working head. When the manual drive shaft 20 is not needed to control the electric handle 200 to drive the working head, the operator controls the manual operation unit 30 to drive the manual drive shaft 20 from the first position to the second position, disengaging the manual drive shaft 20 from the electric handle 200.

[0057] Furthermore, such as Figure 2 As shown, the manual operation unit 30 is rotatably connected to the end of the manual drive shaft 20 away from the mounting space 11. By controlling the rotation of the manual operation unit 30 relative to the manual drive shaft 20, the manual drive shaft 20 is driven to move to a first position or a second position. The end of the manual drive shaft 20 away from the mounting space 11 extends out of the housing body 10, and the manual operation unit 30 is rotatably connected to the end of the manual drive shaft 20 extending out of the housing body 10.

[0058] When the electric handle 200 is working normally, the manual drive shaft 20 is in the second position. When the manual drive shaft 20 is needed to control the electric handle 200 to drive the working head, the operator rotates the manual operating unit 30 to move the manual drive shaft 20 from the second position to the first position, connecting the manual drive shaft 20 to the electric handle 200. Then, the operator controls the manual drive shaft 20 to rotate, driving the handle drive shaft of the electric handle 200 to drive the working head, achieving the effect of manual operation of the working head. When the manual drive shaft 20 is not needed to control the electric handle 200 to drive the working head, the operator rotates the manual operating unit 30 to move the manual drive shaft 20 from the first position to the second position, disengaging the manual drive shaft 20 from the electric handle 200.

[0059] In some embodiments of the present invention, such as Figures 2-5As shown, the sterile housing 100 may further include: a pivot shaft 31, a manual drive shaft 20 having a first pivot hole 22, a manual operation part 30 having a second pivot hole 32, and the pivot shaft 31 passing through the first pivot hole 22 and the second pivot hole 32. Furthermore, the manual operation unit 30 is constructed as a pull ring structure, which has a bent portion 33. The bent portion 33 is provided with a second pivot hole 32. Specifically, a notch 34 is formed between the two ends of the pull ring structure. Both ends of the pull ring structure have a bent portion 33, and a notch 34 is formed between the two bent portions 33. Each bent portion 33 is provided with a second pivot hole 32. The two second pivot holes 32 on the two bent portions 33 are arranged opposite to each other. The end of the manual drive shaft 20 away from the installation space 11 is provided with a first pivot hole 22. The end of the manual drive shaft 20 away from the installation space 11 is installed at the notch 34. The first pivot hole 22 and the second pivot hole 32 are arranged opposite to each other. The pivot shaft 31 passes through the first pivot hole 22 and the second pivot hole 32 at the same time, thereby realizing the rotational connection between the manual operation unit 30 and the manual drive shaft 20.

[0060] Furthermore, along the extending direction of the manual operation section 30, the end of the bent section 33 has a first end face 35, and the distance between the first end face 35 and the central axis of the second pivot hole 32 is A mm. Along the width direction of the manual operation section 30, the width direction of the manual operation section 30 is... Figure 5 In the direction of the lines, the bent portion 33 has a second end face 36, and the distance between the second end face 36 and the central axis of the second pivot hole 32 is Bmm, satisfying the relationship: Amm < Bmm. Wherein, as... Figure 1 As shown, when the manual drive shaft 20 is in the second position, the second end face 36 is in contact with and limited by the housing body 10. When the manual drive shaft 20 needs to control the electric handle 200 to drive the working head, the operator rotates the manual operating part 30 to separate the second end face 36 from the housing body 10, so that the first end face 35 is opposite to the housing body 10. Since Amm < Bmm, the manual drive shaft 20 can be moved from the second position to the first position by pushing the manual operating part 30 toward the installation space 11, so that the manual drive shaft 20 is connected to the electric handle 200. When the manual drive shaft 20 does not need to control the electric handle 200 to drive the working head, the manual drive shaft 20 can be moved from the first position to the second position by pulling the manual operating part 30, so that the manual drive shaft 20 is separated from the electric handle 200. Then, the manual operating part 30 is rotated to make the second end face 36 contact and limit with the housing body 10, and the manual drive shaft 20 cannot move freely along the axial direction.

[0061] In some embodiments of the present invention, such as Figures 2-5As shown, the sterile housing 100 may further include: an elastic element 40, which may be configured as a spring; a first stop wall 14 is provided on the inner sidewall of the mounting hole 13, the first stop wall 14 is provided near the end of the mounting hole 13 away from the mounting space 11; a second stop wall 21 is provided on the outer sidewall of the manual drive shaft 20; and the elastic element 40 is disposed between the first stop wall 14 and the second stop wall 21. The elastic element 40 is disposed within the mounting hole 13 and sleeved on the outside of the manual drive shaft 20. When the manual drive shaft 20 is in the second position, the elastic element 40 is compressed between the first stop wall 14 and the second stop wall 21, at which time the elastic element 40 has elastic force. When the manual drive shaft 20 is needed to control the electric handle 200 to drive the working head, the operator rotates the manual operating part 30 to separate the second end face 36 from the housing body 10, so that the first end face 35 is positioned opposite the housing body 10. Under the action of the spring force, the manual drive shaft 20 will move from the second position to the first position, thereby realizing the automatic connection between the manual drive shaft 20 and the electric handle 200. When the manual drive shaft 20 is not needed to control the electric handle 200 to drive the working head, the manual drive shaft 20 is moved from the first position to the second position by pulling the manual operating part 30. The spring is compressed by the first stop wall 14 and the second stop wall 21, thereby giving the spring elastic force.

[0062] In some embodiments of the present invention, the sterile housing 100 further includes a manual operation unit 30, which is detachably connected to a manual drive shaft 20. The manual operation unit 30 is used to drive the manual drive shaft 20 to move to a first position or a second position. Specifically, when the manual drive shaft 20 needs to control the electric handle 200 to drive the working head, the manual operation unit 30 is connected to the manual drive shaft 20. The operator controls the manual operation unit 30 to drive the manual drive shaft 20 from the second position to the first position, connecting the manual drive shaft 20 to the electric handle 200. At this time, the operating end 23 is inserted into the operating hole 201. Then, by rotating the manual operation unit 30, the manual drive shaft 20 drives the handle drive shaft of the electric handle 200 to drive the working head, achieving the effect of manually operating the working head. When the manual drive shaft 20 is not required to control the electric handle 200 to drive the working head, the operator controls the manual operation unit 30 to drive the manual drive shaft 20 from the first position to the second position, so that the manual drive shaft 20 is separated from the electric handle 200, and then the manual operation unit 30 is removed from the manual drive shaft 20.
