[0043] like Figure 1 As shown, an embodiment of the present invention provides a control device for a handheld surgical device, which includes:

[0044] A control box, wherein a motor driver and a peristaltic pump controller are arranged in the control box;

[0045] The motor driver is used to be electrically connected to the motor in the handheld surgical device;

[0046] The peristaltic pump controller is used to be electrically connected to the peristaltic pump, and the peristaltic pump is used to provide power to the flushing tube of the handheld surgical device, that is, to make the flushing liquid in the flushing tube flow smoothly;

[0047] A foot switch is electrically connected to the motor driver and the peristaltic pump controller respectively. The peristaltic pump and the motor can be controlled to start at the same time by stepping on the foot switch. When the operation is finished, the foot switch can be released. One person can complete the operation, which is convenient and efficient.

[0048] It should be noted that the motor driver and the peristaltic pump controller are both existing structures.

[0049] In addition, the peristaltic pump is specifically composed of three parts: a drive mechanism such as a drive motor, a pump head, and a hose. The peristaltic pump is like squeezing a hose full of fluid with your fingers, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump is also based on the same principle, except that the fingers are replaced by rollers. The fluid is pumped by alternately squeezing and releasing the elastic delivery hose of the pump. Just like squeezing a hose with two fingers, as the fingers move, negative pressure is formed in the tube, and the liquid flows.

[0050] In a specific embodiment, the driving mechanism is arranged in the control box to protect the driving mechanism, and the driving mechanism is electrically connected to the peristaltic pump controller; the pump head is fixed to the side wall outside the control box, and the flushing tube of the handheld surgical device is used to be connected to the pump head, which facilitates the connection between the flushing tube of the handheld surgical device and the pump head, specifically, facilitates the connection between the flushing tube and the hose in the pump head.

[0051] In a specific embodiment, the foot switch is arranged on the ground to facilitate foot control by the surgical operator; the foot switch includes a base and a foot button arranged on the base, the foot button is connected to two connecting wires, one connecting wire is connected to the motor driver, and the other connecting wire is connected to the peristaltic pump controller. By fixing the base to the ground, the motor and the peristaltic pump can be controlled simultaneously by pressing the foot button.

[0052] like Figure 2 As shown, another embodiment of the present invention provides a handheld surgical device, which includes:

[0053] A handheld part, the handheld part comprises a handheld housing 1, a motor housing 2 is arranged inside the handheld housing 1, and a motor is fixed inside the motor housing 2;

[0054] The control device of the handheld surgical device;

[0055] A peristaltic pump, installed in the control box;

[0056] The motor is electrically connected to the motor driver;

[0057] The peristaltic pump is electrically connected to the peristaltic pump controller. The foot switch is electrically connected to the motor driver and the peristaltic pump controller respectively. By stepping on the foot switch, the peristaltic pump and the motor can be controlled to start at the same time. When the operation is completed, the foot switch can be released. One person can complete the operation, which is convenient and efficient.

[0058] In a specific embodiment, the handheld surgical device further includes: a cooling liquid flow channel 13, which is provided between the inner periphery of the handheld housing 1 and the outer periphery of the motor housing 2;

[0059] A flushing port 5 extends along the inner side of the front end of the handheld housing 1 toward the coolant flow channel 13 and communicates with the coolant flow channel 13;

[0060] The liquid inlet 10 is located at one end of the handheld housing 1 away from the flushing port 5, and is connected to the coolant flow channel 13. The liquid inlet 10 is connected to a flushing pipe 11, and the flushing pipe 11 is used to connect to a cooling source. When the handheld surgical device is working, the coolant enters the coolant flow channel 13 from the liquid inlet 10, surrounds the outer periphery of the motor housing 2 to cool the working motor, and prevents the motor from burning out under continuous high temperature conditions. It can also reduce the temperature of the handheld housing 1, making it easier for medical staff to hold it; the coolant flowing through the motor housing 2 is sprayed out from the flushing port 5, and can be used to cool the milling drill 4 at the front end of the handheld housing 1 and clean the surgical wound. The structure is simple and easy to operate.

[0061] In addition, by providing a cooling system between the handheld housing 1 and the motor housing 2, on the one hand, it is convenient to cool the motor and the handheld housing 1, as well as to cool the milling drill 4 at the front end of the handheld housing 1 and clean the surgical wound; on the other hand, in this embodiment, the motor is placed in the handheld housing 1 to form an integrated structure, so that the overall structure is compact and portable, and can be disinfected and discarded at the same time, so as to achieve true no secondary use and cross infection.

[0062] It should be noted that the “front end” of the handheld housing 1 refers to the surgical operation end of the handheld housing 1, i.e. Figure 2 Of course, it can be understood that the "rear end" of the handheld housing 1 refers to the end of the handheld housing 1 away from the surgical operation end, that is, Figure 2 right end shown in .

[0063] In a specific embodiment, a sandwich is formed between the inner periphery of the handheld housing 1 and the outer periphery of the motor housing 2. The outer diameter of the motor housing 2 can be set to be smaller than the inner diameter of the handheld housing 1, so as to form an annular gap between the motor housing 2 and the handheld housing 1. The annular gap serves as the sandwich to constitute the coolant flow channel 13. Thus, the coolant can flow through the sandwich, surround the outer periphery of the motor housing 2, cool the motor housing 2, and then cool the motor in the motor housing 2 to prevent the motor from overheating, and also cool the handheld housing 1 to prevent it from getting hot.

[0064] It should be noted that, in the present invention, the cooling liquid can be liquids such as physiological saline, sterilizing water, disinfectant, etc. Of course, these liquids used need to be harmless to the human body to avoid affecting the surgical wound.

[0065] In a specific embodiment, grooves are formed on the inner periphery of the handheld housing 1 and / or the outer periphery of the motor housing 2, and the grooves constitute the coolant flow channel 13 between the inner periphery of the handheld housing 1 and the outer periphery of the motor housing 2. In other words, grooves can be formed on the inner periphery of the handheld housing 1 alone, or on the outer periphery of the motor housing 2 alone, or on both the inner periphery of the handheld housing 1 and the outer periphery of the motor housing 2 at the same time; the grooves are used for the circulation of coolant.

[0066] Specifically, the groove may be in the form of a groove, or may be formed as a space between two adjacent dividing strips. The specific form is not limited as long as it can guide the flow of the coolant.

[0067] In a specific embodiment, the groove extends in a spiral shape from one end of the handheld housing 1 to the other end along the inner circumference of the handheld housing 1;

[0068] And / or, the groove extends in a spiral shape from one end of the motor housing 2 along the outer circumference of the motor housing 2 to the other end. Setting the groove in a spiral shape can guide the coolant to flow in a spiral shape to the entire outer circumference of the motor housing 2, and can also cool the motor housing 2, and then cool the motor in the motor housing 2 to prevent the motor from overheating, and also cool the handheld housing 1 to avoid scalding.

[0069] In another specific embodiment, the inner circumference of the handheld housing 1 is provided with a plurality of grooves extending along its axial direction at intervals, and the plurality of grooves and the outer circumference of the motor housing 2 form the coolant flow channel 13;

[0070] And / or, the outer periphery of the motor housing 2 is provided with a plurality of grooves extending along its axial direction, and the plurality of grooves and the inner periphery of the handheld housing 1 form the coolant flow channel 13. Thus, the coolant flows along the grooves from one end of the outer periphery of the motor housing 2 to the other end, and / or, the coolant flows along the grooves from one end of the inner periphery of the handheld housing 1 to the other end, which can also cool the motor housing 2, and then cool the motor in the motor housing 2 to prevent the motor from overheating, and also cool the handheld housing 1 to prevent it from getting hot.

[0071] In addition, the grooves may be in the shape of long strips, waves, etc., and the specific shape is not limited.

[0072] In a specific embodiment, the flushing port 5 is a long hole, which is arranged along the axial direction of the handheld shell 1, and the aperture of the long hole is 0.6-0.8 mm, preferably 0.7 mm; it is ensured that the coolant sprayed from the flushing port 5 has a certain pressure to facilitate flushing of the wound.

[0073] like Figure 2As shown, in a specific embodiment, it also includes a flushing hole 6 provided on the front cap 7, the front cap 7 is docked with the front end of the handheld shell 1, and a sealing ring 8 is provided at the docking position to ensure the sealing effect, the flushing hole 6 is connected with the outlet of the flushing port 5, the aperture of the flushing hole 6 can match the flushing port 5, and the outlet of the flushing hole 6 is inclined toward the axial direction of the handheld shell 1, so that the coolant sprayed from the flushing hole 6 can be directly flushed to the milling drill 4 extending from the front cap 7 at a close distance, which will not affect the normal progress of the operation, but also clean the wound during the operation to avoid infection.

[0074] A specific embodiment, such as Figure 2 As shown, the motor housing 2 is fixed with a mounting sleeve 3 at the output end of the motor, and the mounting sleeve 3 extends out of the handheld housing 1. In order to ensure that the mounting sleeve 3 is firmly connected to the handheld housing 1, an interference fit is adopted between the mounting sleeve 3 and the handheld housing 1, thereby forming a sealed connection between the mounting sleeve 3 and the handheld housing 1, that is, the coolant does not directly pass through the outer periphery of the mounting sleeve 3;

[0075] The output end of the motor is connected to a milling drill 4, which is driven by the motor to rotate so as to cut or grind the surgical site. The axial direction of the mounting sleeve 3 is provided with a through hole for the milling drill 4 to pass through, and in order to ensure the smooth rotation of the milling drill 4, a bearing 9 is provided on the outer fixed sleeve of the milling drill 4, and the outer ring of the bearing 9 is fixed to the inner circumference of the mounting sleeve 3;

[0076] The flushing port 5 extends along the sealed connection between the handheld housing 1 and the mounting sleeve 3 and is connected to the coolant flow channel 13, so that the coolant passing through the coolant flow channel 13 is only sprayed out from the flushing port 5, ensuring that the injection pressure can meet the surgical requirements, and the flushing port 5 is located above the mounting sleeve 3, which does not affect the normal progress of the operation and can also facilitate direct flushing of the milling cutter.

[0077] In a specific embodiment, the handheld housing 1 is provided with a hand-grip rubber layer at the mounting sleeve 3, and the hand-grip rubber layer can be made of a rubber pad, which not only increases the hand feel but also prevents slipping during surgery;

[0078] The end of the handheld housing 1 located at the liquid inlet 10 is also connected to a power cord 12, and the power cord 12 is used to connect to the power interface of the control box to supply power to the motor.

[0079] It can be seen from the above embodiments that the present invention can be controlled by one-touch through a foot switch, and one person can complete the operation, which is convenient and efficient. In addition, it is convenient to cool the motor and the handheld housing, as well as to cool the milling drill at the front end of the handheld housing and clean the surgical wound. Moreover, the motor is placed in the handheld housing to form an integrated structure, so that the overall structure is compact and portable, and can be disinfected and discarded at the same time, so as to achieve true no secondary use and cross infection.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
