While removing the lesions, tissue specimens can be retained for histological evaluation to determine whether there is a lesion, the range and depth of the lesion, the condition of the lesion at the cutting edge (positive or negative cutting edge), and whether there is infiltration and to measure the invasive cancer lesions under the microscope. According to the type of surgical instrument, cervical cone excision includes cervical cold knife cone excision (CKC), cervical electrosurgical excision (EKC), cervical loop electrosurgical excision (LEEP), cervical radiofrequency knife cone excision, cervical cryotherapy, etc. LEEP is the most commonly used surgery now. During the operation, the LEEP knife is used to remove the cone part of the lesion.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0027] Embodiment 1:

[0028] like Figure 1-5 As shown, the cone and soft tissue separation device for full cone cutting surgery provided by the utility model includes: a cutting device and a host, the cutting device is electrically connected to the host, the host supplies power to the cutting device, the cutting device includes an outer tube 1, an electrode 2 is installed in the outer tube 1, a handle 3 is installed at the tail of the outer tube 1, a LEEP knife assembly 4 is plugged and installed at the end of the outer tube 1, the LEEP knife assembly 4 includes a fixing rod 5, the fixing rod 5 is plugged with the end of the outer tube 1, a sleeve 6 is installed on the fixing rod 5 with damping sliding, a telescopic rod 7 is installed on one side of the sleeve 6, a knife head 8 is installed between the telescopic rod 7 and the tip of the fixing rod 5, the knife head 8 adopts the knife head used by the conventional LEEP knife, the knife head 8 is electrically connected to the electrode 2, and when in use, the knife head 8 is adjusted according to the morphology of the patient's lesion. The angle between the blade head 8 and the fixed rod 5 is adjusted. At this time, the sleeve 6 is slid to the side away from the tip of the fixed rod 5, and the tip of the telescopic rod 7 is pressed to shorten the length of the telescopic rod 7. The movement of the sleeve 6 is coordinated to keep the blade head 8 in a straight line. At this time, the angle between the blade head 8 and the fixed rod 5 becomes smaller. If the fixed rod 5 is rotated 360 degrees as the axis, a cone with a smaller cone angle will be cut out. When adjusted in the opposite direction, a cone with a larger cone angle will be cut out. Therefore, by adjusting the angle of the blade head 6, the cut tissue can be more consistent with the patient's lesion morphology, and the thickness of the healthy tissue removed around the lesion can be more uniform, thereby reducing the amount of healthy tissue removed. Therefore, the requirements for surgical techniques are greatly reduced. The operation method of LEEP knife surgery is a well-known technology and will not be repeated here.

[0029] By setting up a LEEP knife assembly 4 including a fixed rod 5, a sleeve 6, a telescopic rod 7 and a knife head 8, by moving the position of the sleeve 6 and coordinating the use of the telescopic rod 7, the angle between the knife head 8 and the fixed rod 5 is adjusted, and the cone angle of the cut cone is changed, so that the cone is more matched with the shape of the lesion, which facilitates the uniform removal of healthy tissue around the lesion and reduces the difficulty of the operation.

[0030] Embodiment 2:

[0031] like Figure 3-4 As shown, the telescopic rod 7 includes an outer sleeve 9 and an inner rod 10, one end of the inner rod 10 is inserted into the outer sleeve 9, the other end of the inner rod 10 is connected to the cutter head 8, one end of the outer sleeve 9 is connected to the sleeve 6, and a damping friction ring 12 is fixedly installed on the inner rod 10, and the material of the damping friction ring 12 is rubber. The outer side of the inner rod 10 is squeezed with the inner wall of the outer sleeve 9 to form a certain amount of friction resistance. When in use, the outer side of the inner rod 10 is pressed to move it into the outer sleeve 9, thereby shortening the length of the entire telescopic rod 7. Due to the existence of the damping friction ring 12, there is a sufficiently large static friction between the inner rod 10 and the outer sleeve 9, so that its length will not change easily.

[0032] By providing the telescopic rod 7 including the outer sleeve 9, the inner rod 10 and the damping friction ring 12, the length of the telescopic rod 7 can be conveniently adjusted, and the length of the telescopic rod 7 will not change easily when a certain external force is applied.

[0033] Embodiment 3:

[0034] like Figure 4 As shown, the inner wall of the outer sleeve 9 is provided with anti-skid patterns 11, which are evenly arranged on the inner wall of the outer sleeve 9. When in use, the damping friction ring 12 is squeezed and contacted with the inner wall of the outer sleeve 9. The anti-skid patterns 11 can increase the resistance between the outer sleeve 9 and the damping friction ring 12, making it difficult for the inner rod 10 to move.

[0035] By providing the anti-slip grooves 11 on the inner wall of the outer sleeve 9, the resistance between the outer sleeve 9 and the damping friction ring 12 can be increased, so that the inner rod 10 is not easy to move.

[0036] Embodiment 4:

[0037] like Figure 4 As shown, a connecting tube 13 is fixedly installed on the sleeve 6, and a limiting rod 14 is installed in the connecting tube 13. One end of the limiting rod 14 is fixedly installed with a clamping plate 15, and the clamping plate 15 is fixedly connected to the outer sleeve 9. A limiting plate 17 is fixedly installed on the limiting rod 14, and a spring 18 is sleeved on the limiting rod 14, and the spring 18 is in a compressed state. Through the compressed spring 18, one end of the limiting rod 14 is pressed tightly against the fixing rod 5. When in use, the clamping plate 15 is pinched and the clamping plate 15 is moved to the side away from the connecting tube 13, thereby moving the limiting rod 14 and disengaging from the fixing rod 5. At this time, the spring 18 is compressed, and the sleeve 6 and the fixing rod 5 are movably connected, which facilitates the axial movement of the sleeve 6 along the fixing rod 5. After loosening the clamping plate 15, the limiting rod 14 is pressed tightly against the fixing rod 5 at one end under the action of the compressed spring 18, thereby fixing the sleeve 6 on the fixing rod 5.

[0038] By providing the connecting pipe 13 , the limiting rod 14 , the clamping plate 15 , the limiting plate 17 and the spring 18 , the sleeve 6 can be conveniently moved and fixed.

[0039] Embodiment 5:

[0040] like Figure 2-4 As shown, a plurality of limit grooves 16 are evenly provided on the fixing rod 5, and the limit grooves 16 are adapted to the limit rod 14. When in use, one end of the limit rod 14 is inserted into one of the limit grooves 16 under the action of the spring 18. By plugging the limit rod 14 into the limit groove 16, the connection strength between the sleeve 6 and the fixing rod 5 is increased, making it difficult for the sleeve 6 to move on the fixing rod 5.

[0041] By evenly providing a plurality of limiting grooves 16 on the fixing rod 5 , the connection strength between the sleeve 6 and the fixing rod 5 can be enhanced.

[0042] Embodiment 6:

[0043] like Figure 2 and Figure 5 As shown, a prismatic plug connector 20 is provided on one side of the fixing rod 5, and a plug slot 19 adapted to the plug connector 20 is provided at one end of the electrode 2. The electrode 2 is rotatably connected to the outer tube 1, and a knob 21 and a connecting wire 22 are installed at the tail of the electrode 2. The connecting wire 22 is used to connect to the host. When in use, the fixing rod 5 is plugged into the electrode 2 through the plug connector 20 and the plug slot 19, and the knob 21 is pinched, and the electrode 2 rotates in the outer tube 1, thereby rotating the fixing rod 5, thereby rotating the cutter head 8, and then cutting the lesion tissue. The cutter head 8 is electrically connected to the electrode 2 through the fixing rod 5 and the plug connector 20, which is used to power the cutter head 8.

[0044] By providing the plug slot 19, the plug connector 20, the knob 21 and the connecting line 22, it is convenient to supply power to the cutter head 8, so as to facilitate the rotation and cutting of the cutter head 8.

[0045] Working principle: When in use, the angle between the blade head 8 and the fixed rod 5 is adjusted according to the shape of the patient's lesion. At this time, the sleeve 6 is slid to the side away from the tip of the fixed rod 5, and the tip of the telescopic rod 7 is pressed to shorten the length of the telescopic rod 7. The movement of the sleeve 6 is coordinated to keep the blade head 8 in a straight line state. At this time, the angle between the blade head 8 and the fixed rod 5 becomes smaller. If the fixed rod 5 is rotated 360 degrees as the axis, a cone with a smaller cone angle will be cut out. When the adjustment is reversed, a cone with a larger cone angle will be cut out. Therefore, by adjusting the angle of the blade head 6, the cut tissue can be more consistent with the shape of the patient's lesion, and the thickness of the healthy tissue removed around the lesion can be more uniform, thereby reducing the amount of healthy tissue removed. Therefore, the requirements for surgical techniques are greatly reduced. During the operation, the handle 3 is held and the outer tube 1 is inserted into the patient's body. The operation method of the LEEP knife surgery is a well-known technology and will not be repeated here.
