[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] like Figure 1 As shown, this utility model provides an electric cutting device for minimally invasive excision of axillary apocrine glands, including a hollow shell 1, a cutting head 13 disposed at one end of the shell 1, and a negative pressure device connected to the other end of the shell 1, such as... Figure 3 As shown, a cutting window 131 is opened on the cutting head 13, and a fixed cutting head 132 is set on the cutting window 131. A drive mechanism is set on the housing 1, and a drive shaft 14 is set inside the housing 1. One end of the drive shaft 14 is connected to the output end of the drive mechanism, and a moving cutting head 15 is set on the other end of the drive shaft 14. The moving cutting head 15 is arranged correspondingly to the fixed cutting head 132. The drive mechanism is used to control the moving cutting head 15 to move linearly and reciprocally parallel to the fixed cutting head 132 through the drive shaft 14, so that the moving cutting head 15 and the fixed cutting head 132 cut the apocrine gland tissue at the cutting window 131. A negative pressure device is used to extract the cut apocrine gland tissue from the housing 1. The drive mechanism is a motor.

[0033] Understandably, by setting a fixed cutting head 132 and a movable cutting head 15, after pressing the apocrine gland tissue against the cutting window 131, the movable cutting head 15 is controlled by a drive mechanism to move linearly back and forth, causing the apocrine gland tissue to be cut off by the fixed cutting head 132 and the movable cutting head 15 and fall into the cutting head 13, where it is then sucked away by negative pressure. Compared to existing technologies, the cutting method using the fixed cutting head 132 and the movable cutting head 15 makes it less likely for the apocrine gland tissue to shift, resulting in a cleaner cut.

[0034] It should be noted that the top of the cutting head 13 is flat, and the fixed cutting head 132 should be flush with the top of the cutting head 13 to ensure the cutting depth and cutting effect.

[0035] In some embodiments, such as Figure 4As shown, two driving columns 16 are arranged in the cutting head 13, the two driving columns 16 are arranged in parallel, the two driving columns 16 are perpendicular to the bottom of the cutting head 13, one end of the driving column 16 is in sliding connection with the bottom of the cutting head 13, the other end of the driving column 16 is connected with the moving cutting head 15, the end of the driving shaft 14 is provided with an eccentric shaft 17, the eccentric shaft 17 is arranged non-coaxially with the driving shaft 14, the eccentric shaft 17 is inserted between the two driving columns 16, so that the eccentric shaft 17 eccentrically moves during the rotation of the driving shaft 14 and drives the moving cutting head 15 to move linearly reciprocatingly. The diameter of the eccentric shaft 17 is slightly smaller than the spacing between the two driving columns 16.

[0036] The eccentric shaft 17 can eccentrically move with the rotation of the driving shaft 14, during the eccentric movement of the eccentric shaft 17, the two driving columns 16 can be driven to move left and right, the driving column 16 drives the moving cutting head 15 to move left and right, so that the moving cutting head 15 and the fixed cutting head 132 shear the apocrine gland tissue.

[0037] Further, a sliding groove is formed in the bottom of the cutting head 13, a sliding block is arranged in the sliding groove in a sliding manner, the sliding block can only slide along the sliding groove, and one end of the driving column 16 is connected with the sliding block.

[0038] The cross sections of the sliding groove and the sliding block can be inversely T-shaped, the upper end of the sliding block extends out of the sliding groove and is in threaded connection or welding with the driving column 16.

[0039] In some embodiments, the fixed cutting head 132 and the moving cutting head 15 are both provided with cutting teeth, and the fixed cutting head 132 and the moving cutting head 15 cut the apocrine gland tissue through the cutting teeth. The sizes of the cutting teeth of the fixed cutting head 132 and the moving cutting head 15 are completely same.

[0040] It can be understood that the moving cutting head 15 is attached directly below the fixed cutting head 132, when the moving cutting head 15 moves linearly reciprocatingly parallel to the fixed cutting head 132, the cutting teeth on the fixed cutting head 132 and the moving cutting head 15 can shear the apocrine gland tissue, and the sheared apocrine gland tissue directly falls into the cutting head 13.

[0041] In some embodiments, a blade is arranged on the driving shaft 14, and the blade is used to further cut the apocrine gland tissue after cutting.

[0042] It should be noted that, Figure 2 and Figure 4 The structure of the blade is not shown in the and the blade is a non-essential structure. The blade can be a spiral blade, so that the cut apocrine gland tissue can be further cut, and the blade should not affect the residue discharge channel between the inner wall of the driving shaft and the cutting rod. In addition, the spiral direction of the blade should be such that the blade can push the cut apocrine gland tissue to the direction of the negative pressure device when the blade rotates.

[0043] In some embodiments, as shown in Figure 1 The shell 1 includes a hand-held part 11 and a cutting rod 12, one end of the hand-held part 11 is provided with a suction connector 111, the other end of the hand-held part 11 is connected with the cutting rod 12, the suction connector 111 is used to connect with a negative pressure device, a cutting head 13 is arranged at one end of the cutting rod 12 away from the hand-held part 11, a driving shaft 14 is arranged in the cutting rod 12, and a slag discharge channel is arranged between the driving shaft 14 and the inner wall of the cutting rod 12.

[0044] It should be noted that the diameter of the cutting rod 12 can be 0.5mm, and the width of the fixed cutting head 132 can be 1mm. The cutting rod 12 is convenient to extend into the subcutaneous tissue of the patient through the cutout for minimally invasive resection of the apocrine gland tissue.

[0045] Further, a driving mechanism is arranged in the hand-held part 11, and a button 112 is arranged on the hand-held part 11, which is used to control the start and stop of the driving mechanism. By arranging the button 112, the start and stop of the driving mechanism can be controlled, so that the operation during the surgery is more simple.

[0046] Further, the negative pressure device is connected in series with the driving mechanism. By connecting the negative pressure device in series with the driving mechanism, the button 112 can also control the on-off of the negative pressure device. When the cutting head 13 reaches the cutting starting point, the button 112 can be pressed to simultaneously start the driving mechanism and the negative pressure device.

[0047] In some embodiments, as shown in Figure 1 A pressing mechanism 2 is arranged on the shell 1, the pressing mechanism 2 includes a pressing plate 21 and a stand column 22, one end of the pressing plate 21 is slidingly connected with the stand column 22, the other end of the pressing plate 21 extends above the cutting window 131, a fixing member 23 is arranged on the pressing plate 21, and the fixing member 23 is used to adjust the fixed height of the pressing plate 21 on the stand column 22.

[0048] The stand column 22 can be integrated with the cutting rod 12, the stand column 22 is arranged close to the hand-held part 11, the fixing member 23 can be a screw, the fixing member 23 is threadedly connected with the pressing plate 21, the pressing plate 21 and the stand column 22 can be fixed by tightening the fixing member 23, and in addition, a scale can be arranged on the stand column 22, the scale can indicate the distance between the pressing plate 21 and the cutting window 131, so that the cutting thickness can be more accurately controlled.

[0049] In some embodiments, the fixed cutting head 132 is detachably fixedly connected with the cutting head 13.

[0050] It should be noted that the fixed cutting head 132 and the movable cutting head 15 will become less sharp after being used for a period of time, which may cause the cutting to be not clean or affect the cutting efficiency. Therefore, the fixed cutting head 132 can be detachably fixedly connected to the cutting window 131 of the cutting head 13 in a buckle or bolt manner. The movable cutting head 15 can be detachably fixedly connected to the driving column 16 in a bolt manner. Since the movable cutting head 15 is arranged directly below the fixed cutting head 132, the movable cutting head 15 can be removed after the fixed cutting head 132 is removed, so that the fixed cutting head 132 and the movable cutting head 15 can be replaced.

[0051] In some embodiments, as shown in FIG. 1, the cutting head 13 is detachably connected to the cutting rod 12. The cutting head 13 and the cutting rod 12 can be connected in a threaded connection or a buckle joint. The cutting head 13 is disposable consumables, which does not need to be cleaned after use and can be directly replaced. In this way, the problem that the tissue in the cutting head 13 cannot be cleaned out can be avoided. Compared with replacing the fixed cutting head 132 and the movable cutting head 15, the cutting head 13 is more convenient to replace. Figure 5

[0052] The use method of the electric cutting device for minimally invasive resection of axillary apocrine glands is as follows: a 1cm minimally invasive incision is made under the armpit of a patient, the cutting rod 12 is inserted into the subcutaneous tissue through the minimally invasive incision by holding the hand-held part 11, and in the case that the button 112 is not pressed, there is no negative pressure at the cutting window 131. When the cutting head 13 reaches the surgical area, the height of the pressing plate 21 is adjusted by the fixing part 23 and the pressing plate 21 is fixed, the apocrine gland tissue is pressed at the cutting window 131, the button 112 is pressed, the negative pressure device and the driving mechanism are started, and the apocrine gland is cut. The cutting can be in a strip cutting manner, that is, after the cutting head 13 reaches the end of the apocrine gland tissue, the cutting is started, the cutting head 13 retreats and cuts in the direction of the minimally invasive incision, so that a longitudinal strip of apocrine gland tissue is cut off, and the width of 1cm can be cut at a time (if the width of the fixed cutting head 132 is 1cm). During the cutting process, the pressing plate 21 is always limited to ensure the cutting thickness, and the cutting is formed at a time. If the range of the apocrine gland tissue is 10cm, about 10 times of cutting is needed to cut the apocrine gland completely.

[0053] The above-described embodiments are only used to illustrate the technical solutions of the present application, but not limit the same. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features thereof.
