[0001] This utility model relates to the field of medical device technology, and in particular to a cutting handle, cutting device and cutting system with a suction channel. Background Technology

[0002] A planer handle is a cutting handle with a suction channel. During surgery, by adapting it to a tool assembly with a tissue channel, power can be output to the tool assembly to cut the tissue and then extract the cut tissue through the tissue channel and suction channel. For example, in ear, nose, and throat surgery, a planer tool adapted to this planer handle can be selected to remove and remove soft tissue, or a nasal drill bit with a tissue channel can be adapted to the planer handle to remove and remove bone tissue.

[0003] During the procedure, the surgeon operates the planer by holding a planer handle. Traditional planer handles are prone to slippage during operation, which can affect the reliability of the surgery. Utility Model Content

[0004] Therefore, it is necessary to provide a cutting handle, cutting device, and cutting system to address the technical problem of slippage during operation, which affects the reliability of the surgery.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the limiting protrusion is used to abut against the middle finger to restrict the movement of the middle finger toward the front end of the handle housing.

[0009] In one embodiment, the limiting protrusion has an abutting surface facing away from the front end of the handle housing;

[0010] Wherein, the contact surface is a concave arc surface; and / or, the contact surface is connected to the outer surface of the gripping part by an arc transition.

[0011] In one embodiment, the handle housing is further provided with an operating component for operating the cutting handle, and the operating component and the limiting protrusion are respectively located on opposite sides of the grip portion.

[0012] In one embodiment, the limiting groove is disposed on the side of the limiting protrusion, and the limiting groove and the limiting protrusion are distributed circumferentially along the gripping portion.

[0013] In one embodiment, at least one limiting groove is a first limiting groove, which is used for thumb pressure to limit thumb slippage; at least one limiting groove is a second limiting groove, which is used for index finger pressure to limit index finger slippage; the limiting protrusion is disposed in the middle part of the first limiting groove and the second limiting groove.

[0014] In one embodiment, the handle housing is further provided with an operating component for operating the cutting handle, and the operating component is located within the operating space of the index finger.

[0015] In one embodiment, the operating component is located at the middle part between the first limiting groove and the second limiting groove; and / or, the gripping part is further provided with a mounting protrusion, and the operating component is disposed on the mounting protrusion.

[0016] In one embodiment, the operating component is located between the first limiting groove and the second limiting groove; the operating component and the limiting protrusion are respectively located on opposite sides of the gripping portion along a first direction, and the first limiting groove and the second limiting groove are respectively located on opposite sides of the limiting protrusion along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] In one embodiment, a cutting system is provided, including a main unit (not shown) and a cutting device. The main unit and the cutting device are electrically connected, thereby enabling the main unit to provide power, control signals, and other functions to the cutting device, and to perform surgical operations such as removing diseased tissue using the cutting device. Furthermore, the cutting device can be any of the cutting devices described in the following embodiments, which are less prone to slippage during use, ensuring reliable surgical procedures.

[0031] Of course, the main unit can also provide suction force to the cutting device, allowing the tissue cut by the cutting device to be discharged from the cutting device under negative pressure. The main unit can be a component from existing technology, which will not be elaborated upon here.

[0032] It should be noted that the cutting device of this application embodiment can be applied in ear, nose and throat surgery, joint surgery, or other surgeries. For ease of understanding, the cutting device in the accompanying drawings of the following embodiments is described using a planing device as an example.

[0033] In one embodiment, a cutting device is provided, including a tool assembly (not shown) and a cutting handle 100 having a suction channel (not shown). The tool assembly is adapted to the cutting handle 100, which is used to drive the tool assembly to cut tissue. For example, Figure 5 The cutting handle 100 is a planer handle, which is in a state of being adapted and connected to the tool assembly. At this time, the tool assembly can be a planer assembly or a nasal drill bit with a tissue channel. The tool assembly is connected to the cutting handle 100 by a plug-in or snap-fit ​​method. Thus, by holding the cutting handle 100, surgical operations such as removing diseased tissue can be performed using the tool assembly. Furthermore, the cutting handle 100 is not prone to slippage during use, ensuring reliable surgical procedures. The cutting handle can be any of the following embodiments.

[0034] The tool assembly can be an existing component, which will not be described in detail here. The main unit and the cutting handle 100 are electrically connected by wires, cables, or the like; in addition, the main unit can provide negative pressure to discharge the tissue cut by the tool assembly through the tissue channel of the tool and the suction channel of the cutting handle 100.

[0035] like Figures 1 to 5As shown, in one embodiment, a cutting handle 100 with a suction channel is provided, including a handle housing 110. The handle housing 110 has a cylindrical gripping portion and a limiting portion 120 provided on the gripping portion. Thus, the operator can grip the entire handle housing 110 by holding the gripping portion. Furthermore, the cutting tool assembly is connected to the front end of the handle housing 110 by a plug-in or snap-fit ​​method. After the operator grips the gripping portion of the handle housing 110, they can operate the cutting tool assembly to perform surgical operations such as removing diseased tissue. Simultaneously, the limiting portion 120 is used to limit the movement of the gripping fingers relative to the handle housing 110. The limiting portion 120 includes a limiting protrusion 121 protruding from the outer surface of the gripping portion and a limiting groove recessed into the outer surface of the gripping portion.

[0036] It should be noted that the cylindrical shape can be a round cylinder, an elliptical cylinder, or other cylindrical structures with regular or irregular cross-sectional shapes.

[0037] In the above embodiment, the cutting handle 100 with a suction channel allows the operator to grip the gripping part of the handle housing 110 with their fingers during surgery. The limiting part 120 on the gripping part limits the gripping fingers. During the application of force, the limiting protrusion 121 and the limiting groove can restrict the movement of the corresponding gripping fingers relative to the handle housing 110 and prevent slippage. This avoids the gripping fingers from moving relative to the handle housing 110, which helps improve the reliability of the operator's grip on the cutting handle and thus helps ensure the quality and effect of the surgery.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the limiting protrusion 121 is used to abut against the middle finger 230 to restrict the movement of the middle finger 230 toward the front end of the handle housing 110. Thus, after the operator's fingers grip the gripping part of the handle housing 110, the limiting protrusion 121 and the middle finger 230 abut against each other. During the application of force, the middle finger 230 is restricted by the limiting protrusion 121 and cannot move relative to the handle housing 110 toward the front end, thereby preventing slippage and ensuring reliable surgical procedures. Furthermore, the abutment between the limiting protrusion 121 and the middle finger allows the operator to more intuitively feel the interaction force between the limiting protrusion 121 and the middle finger, which helps the middle finger apply accurate force to the handle housing 110 to complete the corresponding surgical operation, ensuring surgical quality and effectiveness.

[0039] like Figure 1 and Figure 2As shown, the limiting protrusion 121 further has an abutting surface 1211 facing away from the front end of the handle housing 110. Thus, when the operator's fingers grip the gripping part of the handle housing 110, the abutting surface 1211 abuts against the middle finger 230. Optionally, the abutting surface 1211 is a concave arc surface. Since fingers are generally cylindrical, the concave arc surface design allows for a larger contact area between the finger and the abutting surface 1211, reducing slippage and ensuring more even force distribution at the contact point, resulting in a better user experience. Optionally, the abutting surface 1211 is connected to the outer surface of the gripping part with an arc transition. This makes the contact between the middle finger 230 and the abutting surface 1211 smoother, preventing stress from being concentrated at the connection between the gripping part and the abutting surface 1211 when the middle finger 230 applies force, thus avoiding pressure sores, scratches, or cuts to the middle finger 230.

[0040] like Figure 1 and Figure 2 As shown, the handle housing 110 also includes an operating component 130 for manipulating the cutting handle, and the operating component 130 and the limiting protrusion 121 are located on opposite sides of the grip portion. Thus, see... Figure 5 When the operator holds the cutting handle, the middle finger 230 abuts against the limiting protrusion 121, and the operating component 130 is within the operating position of the index finger, which facilitates one-handed operation.

[0041] See also Figures 1 to 5 In some embodiments, a limiting groove is disposed beside a limiting protrusion, and the limiting groove and the limiting protrusion 121 are distributed circumferentially along the gripping portion. Thus, when the operator grips the cutting handle, different fingers can engage with the limiting protrusion 121 and the limiting groove respectively.

[0042] In one embodiment, at least one limiting groove is a first limiting groove 122. The first limiting groove 122 is used for the thumb 210 to press and prevent slippage, i.e., to limit the movement of the thumb 210 relative to the handle housing 110. Thus, after the operator's fingers grip the gripping portion of the handle housing 110, the thumb 210 is at least partially pressed into the first limiting groove 122 for positioning. During the application of force, the thumb 210 cannot move relative to the handle housing 110, thereby preventing slippage and ensuring reliable surgical procedures. Furthermore, the positioning of the thumb 210 by the first limiting groove 122, combined with the resistance of the limiting protrusion 121 to the middle finger 230, makes it less likely for the operator's entire palm to move relative to the handle housing 110 during the application of force, further effectively preventing slippage.

[0043] The contour of the first limiting groove 122 can match at least part of the contour of the thumb 210, which facilitates the positioning and limiting of the thumb 210 and ensures a comfortable grip.

[0044] In one possible implementation, the surface of the thumb pad 210 can be in contact with the surface of the first limiting groove 122 over a large area, thereby increasing the friction force by increasing the contact area and preventing slippage. In another possible implementation, the first limiting groove 122 can also be in contact with the thumb pad of the thumb over a small area, with the edge of the first limiting groove 122 contacting the thumb pad of the thumb, which can increase the coefficient of friction between the thumb and the handle housing 110, thereby increasing the friction force and preventing slippage. Of course, the coefficient of friction can also be increased by providing anti-slip textures or other anti-slip structures on the surface of the first limiting groove 122, which can also prevent slippage.

[0045] like Figure 2 , Figure 3 and Figure 4 As shown, optionally, at least one limiting groove is a second limiting groove 123. The limiting protrusion is located at the middle portion of the first limiting groove 122 and the second limiting groove 123, meaning the first limiting groove 122 and the second limiting groove 123 are located on opposite sides of the gripping portion, for example, the first limiting groove 122 and the second limiting groove 123 are located on the left and right sides of the gripping portion, respectively. Furthermore, the second limiting groove 123 is used for the index finger 220 to press and restrict the sliding of the index finger 220 relative to the handle housing 110. Thus, after the operator's fingers grip the gripping portion of the handle housing 110, the index finger 220 is at least partially pressed into the second limiting groove 123 for positioning (for example, the pad of the index finger 220 is pressed into the second limiting groove 123 for positioning). During the application of force, the index finger 220 cannot move relative to the handle housing 110 towards the handle housing 110, thereby preventing slippage and ensuring reliable surgical procedures. Moreover, the positioning of the thumb 210 by the first limiting groove 122 and the positioning of the index finger 220 by the second limiting groove 123, combined with the resistance of the limiting protrusion 121 to the middle finger 230, make it less likely for the operator's entire palm to move relative to the handle shell 110 during the application of force, thereby more effectively preventing slippage.

[0046] The contour of the second limiting groove 123 can match at least part of the contour of the index finger 220, which facilitates the positioning and limiting of the index finger 220 and ensures a comfortable grip.

[0047] The fingertip of the index finger 220 can be in contact with the surface of the second limiting groove 123 over a large area, increasing the contact area and friction force to prevent slippage. The second limiting groove 123 can also be in contact with the fingertip of the index finger 220 over a small area. The edge of the second limiting groove 123 contacts the fingertip of the index finger 220, which can increase the friction coefficient between the thumb and the handle housing 110 and the second limiting groove 123, thereby increasing the friction force and preventing slippage. Of course, the friction coefficient can also be increased by setting anti-slip textures or other anti-slip structures on the surface of the second limiting groove 123, which can also prevent slippage.

[0048] To facilitate understanding of how the limiting grooves and limiting protrusions 121 distributed axially along the grip area collectively restrict the relative movement of the gripping fingers relative to the handle housing 110, please refer to [reference needed]. Figures 1 to 5 The gripping area includes a finger gripping section, with a limiting protrusion 121, a first limiting groove 122, and a second limiting groove 123 distributed circumferentially along the finger gripping section. Thus, when the operator grips the cutting handle, the thumb 210 can grip the first limiting groove 122 beside the limiting protrusion 121, and the index finger 220 can grip the second limiting groove 123 on the other side of the limiting protrusion 121. The thumb 210, middle finger 230, and index finger 220 work together against the handle housing 110, facilitating precise control, making the grip more comfortable and convenient, and enabling efficient surgical operations and force application.

[0049] Of course, the outer surface of the gripping part can also form a tiger's mouth abutment section. Along the axial direction of the gripping part, the tiger's mouth abutment section is set at the rear end of the finger gripping section. After the operator's fingers grip the finger gripping section of the gripping part, the tiger's mouth can rest against the tiger's mouth abutment section. That is, the way of holding the cutting handle is similar to the tiger's mouth holding pen posture, making the grip more convenient and comfortable, and facilitating efficient surgical operation and force application.

[0050] like Figures 1 to 5 In the illustrated embodiment, the handle housing 110 is further provided with an operating component 130 for controlling the cutting handle, and the operating component 130 is located within the operating space of the index finger 220. Thus, after the operator's fingers grip the gripping part, they can use the index finger 220 to perform pressing or other operating actions on the operating component 130 to trigger corresponding operating commands to complete the corresponding surgical operation.

[0051] Optionally, the operating component 130 is located at the middle part between the first limiting groove 122 and the second limiting groove 123. Of course, in this utility model, it is not excluded that the operating component 130 is located in front of or behind the index finger pressing area, or in any other position within the operating space of the index finger 220.

[0052] Optionally, the operating component 130 can be a button structure such as a push switch.

[0053] like Figures 1 to 5 As shown, the grip area also has a mounting protrusion 140. The operating component 130 is located on the mounting protrusion 140. Thus, the mounting protrusion 140 makes the operating component 130 protrude further from the handle housing 110, facilitating pressing and other operations by the index finger 220, improving ease of use. Furthermore, the operating component 130 is more prominent, making it easier to operate intuitively and precisely.

[0054] like Figure 3 and Figure 4 As shown, in one embodiment, the operating part 130 is located between the first limiting groove 122 and the second limiting groove 123. The operating part 130 and the limiting protrusion 121 are located on opposite sides of the gripping part along a first direction. Furthermore, the first limiting groove 122 and the second limiting groove 123 are located on opposite sides of the limiting protrusion 121 along a second direction, and the first direction and the second direction are perpendicular to each other. Thus, when the hand grasps the handle housing 110, the thumb 210 is at least partially pressed into the first limiting groove 122, the index finger 220 is at least partially pressed into the second limiting groove 123, and the middle finger 230 is at least partially in contact with the limiting protrusion 121. This makes it less likely for the operator's entire palm to move relative to the handle housing 110 during the application of force, thereby more effectively preventing slippage. Furthermore, the operating component 130 is very likely to be within the operator's line of sight, making it easier for the operator to intuitively and accurately control the operating component 130. At the same time, the index finger 220 can also perform pressing and other operations on the operating component 130, improving the convenience of use.

[0055] In one embodiment, the first direction is Figure 1 , Figure 2 , Figure 4 The vertical direction shown, the second direction is Figure 4 The left and right directions are shown. The mounting protrusion 140 and the limiting protrusion 121 are located on the upper and lower sides of the handle housing 110, respectively, and the first limiting groove 122 and the second limiting groove 123 are located on the left and right sides of the handle housing 110, respectively.
