Thus, when the blade 501 can not cut the fascia, the medical electric knife device can be connected to the push knife 5 for cutting by using the electric knife.
Embodiment 2:
the embodiment is further optimized in embodiment 1, and the specific optimization scheme is as follows: the included angle between the two symmetrically arranged clamping frames (the first clamping frame 3 and the second clamping frame 4) and the adjusting column 1 is controlled to be 120-145 degrees. In the embodiment, the included angle between the clamping frame and the adjusting column 1 is set to be 120-145 degrees, so that the clamping frame can obliquely enter the skin, the fascia can be clamped without pressing the two clamping frames and the push broach 5, the skin and surrounding tissues can not be damaged, and the included angle is set to be 120-145 degrees, so that the hand-holding operation of a doctor is facilitated, and the operation is simple, convenient and effective. Other operations in this embodiment are the same as those in embodiment 1, and are not described herein.
Embodiment 3:
the embodiment is further optimized in embodiment 1, and the specific optimization scheme is as follows: the symmetrical positions of the inner walls of the tubes of the two clamping frames are respectively inwards recessed to form sliding grooves 8, and the two transverse sides of the push broach 5 can be positioned in the sliding grooves 8, which is shown in figure 2. Therefore, after the push broach 5 is connected between the two clamping frames in a sliding mode, if the inner walls of the two clamping frames are not provided with the sliding grooves, the push broach 5 can rotate in the hollow inner wall formed by the two clamping frames, and after the push broach rotates, the push broach 5 possibly does not face the fascia, so that the cutting efficiency is influenced, and surrounding tissues are possibly damaged. When the two sides of the push broach 5 are slidably connected in the sliding grooves 8, the push broach 5 cannot rotate when sliding between the clamping frames, so that the push broach mechanism is just opposite to the fascia no matter the push broach mechanism is pushed or pulled out, and the cutting task can be quickly and effectively finished. Other operations in this embodiment are the same as those in embodiment 1, and are not described herein.
Embodiment 4:
the embodiment is a further optimization of the embodiment 3, and the specific optimization scheme is as follows: the sliding groove 8 in embodiment 3 is arranged in a T shape, that is, arranged as a T-shaped sliding groove 801, see fig. 3, and at the same time, the push broach 5 is arranged in an "i" shape, the push broach 5 is matched with the two T-shaped sliding grooves 801 between the first holding frame 3 and the second holding frame 4, and the position of the blade 501 is in the vertical direction of the "i" shaped push broach 5. The purpose of this embodiment is optimized in such a way that if the distance between the first clamping frame 3 and the second clamping frame 4 is too large in the manner according to embodiment 3, the size of the selected push broach 5 cannot be completely matched, so that the push broach 5 still may rotate between the two clamping frames, and the expected purpose cannot be achieved, we select the T-shaped sliding groove 801 and the "i" shaped push broach according to this embodiment, which can avoid the problem, and after the size of the push broach 5 is selected, the distance between the first clamping frame 3 and the second clamping frame 4 is adjusted according to the size of the push broach 5 until the push broach 5 can be pushed into the two clamping frames, so that the push broach 5 never rotates between the two clamping frames.
The further improvement of the embodiment is that: the front ends of the two clamping frames can be set to be of a semi-cone structure, the inner walls of the semi-cone structure positions of the first clamping frame 3 and the second clamping frame 4 are not provided with the sliding groove 8 (T-shaped sliding groove 801) and are only provided to be close to the position of the cone structure, so that the push broach 5 can only push to the position of the cone structure and can not move forwards any more, the first clamping frame 3, the second clamping frame 4 and the push broach 5 are integrally pushed at the moment, after gluteus contracture fascia is completely cut off, even if the semi-cone structures of the first clamping frame 3 and the second clamping frame 4 touch sciatic nerves at the rear, because the distance between the first clamping frame 3 and the second clamping frame 4 is smaller than the diameter of the sciatic nerves at the rear, the injury of acute structures to sitting bone nerves can be avoided, the injury to patients is avoided, the push broach 5 can only push to the position of the semi-cone structure, and the push of the push broach 5 to exceed, the sharp blade damages the surrounding tissue.
This embodiment is the same as embodiment 3, and will not be described herein.
Embodiment 5:

Referring to the attached drawing 4, the outer side surface of the adjusting column 1 is provided with a locking screw 10, and after the distance between the first clamping frame 3 and the second clamping frame 4 is adjusted, the locking screw 10 on the outer side of the adjusting column 1 is locked, so that the adjusting handle 2 cannot move between the adjusting column 1, the distance between the first clamping frame 3 and the second clamping frame 4 cannot be changed, and the use is more stable.
Other operations in this embodiment are the same as those in embodiment 1, and are not described herein.
Embodiment 6:
the embodiment is further optimized in embodiment 1, and the specific optimization scheme is as follows: with adjusting handle 2 whole setting in adjusting post 1, adjusting post 1 keeps away from two holding frame terminal surface threaded connection adjusting screw 11, and adjusting screw 11 is close to 2 one ends of adjusting handle and rotates to be connected in adjusting handle 2, and when adjusting screw 11 was rotatory, adjusting handle 2 irrotational. In this embodiment, the one end that adjustment handle 2 kept away from two holding framves sets up to hollow end 201, adjusting screw 11 is close to 2 one end fixed connection lugs 12 of adjusting handle, lug 12 is located 2 hollow end 201 of adjusting handle and swivelling joint, and like this, when rotating adjusting screw 11, because adjusting screw 11 and 1 threaded connection of regulation post, when adjusting screw 11 is rotatory, move forward or backward, because adjusting screw 11 rotates with adjusting handle 2 to be connected, adjusting handle 2 does not rotate when adjusting screw 11 rotates, but adjusting screw 11 can drive adjusting handle and move forward or backward, can adjust the distance between two holding framves. This embodiment transfers the linear movement adjustment of adjustment handle 2 to the rotational adjustment of adjusting screw 11, and the adjustment is more accurate.
Other operations in this embodiment are the same as those in embodiment 1 and are not described herein.
The above embodiments are merely illustrative of the technical concepts and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
