It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail with reference to examples.

Example (b):

as shown in fig. 1-6, a muscle distraction device for general surgery department, including electric handle 1, electric handle 1 outer wall fixed mounting has the key 2 that contracts of propping, the tip of electric handle 1 is contained angle symmetry swing joint and has 2 vaulting poles 4, the one end of vaulting pole 4 is located inside electric handle 1, the other end of vaulting pole 4 extends to outside electric handle 1 by the tip of electric handle 1, electric handle 1 is inside to be fixed with installation base 11, the inside flexible motor 3 that inlays of installation base 11, the fixed welding of flexible end of flexible motor 3 has transfer line 31, prop the key and contract motor electric connection for the work of control flexible motor. Stay 5 is fixedly welded at the end part of stay 4 far away from electric handle 1, and pull sheet 6 is detachably connected to stay 5, and pull sheet 6 is located at the opposite surface of the connection surface of stay 5 and stay 4.

In this embodiment, in the operation process, prop open the muscle when performing the operation as needs, at first make the plectrum 6 under two vaulting poles 4 draw close mutual conflict earlier, then slowly control electric handle 1 and stretch into the wound with plectrum 6, when guaranteeing that plectrum 6 bottom stretches into the muscle layer, press the key that props in the key 2 that contracts, in the process of strutting, see that the degree of strutting is suitable, press the action that props the key and stop propping once more, the postoperative, press the key that contracts again, when two plectrums 6 offset, slowly control the device again and take out plectrum 6, so can make the operation in-process, save medical personnel's physical power, improve the operation precision.

The end of the mounting base 11 is symmetrically and fixedly provided with 2 rotating grooves 41, the 2 rotating grooves 41 are respectively positioned at two sides of the transmission rod 31, the rotating grooves 41 are connected with one end of the stay bar 4, the end of the transmission rod 31 far away from the telescopic motor 3 is fixedly connected with the connecting block 32, the transmission rod 31 is symmetrically connected with 2 connecting rods 33 through the connecting block 32, and the end of the connecting rod 33 far away from the transmission rod 31 is hinged with the stay bar 4.

In this embodiment, when pressing the vaulting key, the flexible end of flexible motor 3 corresponds makes the motion of stretching, drives connecting rod and connecting rod 33 for 2 connecting rods 33 are to the both sides motion, drive vaulting pole 4 and open, and when pressing the key that contracts on the same principle, make 2 connecting rods 33 to the middle motion, drive vaulting pole 4 and contract.

Stay 5 and a plurality of screw holes 51 of equidistant integrated into one piece, plectrum 6 and stud 61 integrated into one piece, plectrum 6 passes through stud 61 and screw hole 51 with stay 5 and is connected, and the contained angle of plectrum 6 and stud 61 axis is 5, and plectrum 6 keeps away from stud 61 one end and is circular-arc.

In this embodiment, according to the size of the operation wound determined by the medical staff, 1 or more than one shifting piece 6 can be selected and installed on the stay 5 to correspond to different operation wounds; the included angle of the poking piece 6 and the central axis of the stud 61 is set to be 5 degrees (namely the inclined arrangement of the poking piece 6), so that the muscle injury caused by the same opening width of the muscle and the upper skin in the operation process can be avoided, and the thinner the poking piece is closer to the bottom of the muscle, the easier the device is to stretch into the muscle seam.

The stay bar 4 and the electric handle 1 form an included angle of 20 degrees.

In this embodiment, in the operation process, utilize to be 20 contained angles between vaulting pole 4 and the electric handle 1, medical personnel operate the electric handle need not keep the horizontality with the opening, can place the hand on the opening by a take the altitude, possess better sight to and hand position, ensure that the device can stretch into the operation opening with the exact form.

The outer layer of the shifting sheet 6 is an anti-skid silica gel layer 62.

In the embodiment, the poking sheet 6 can be prevented from sliding off in the opening process, so that the operation process is delayed.

The working principle is as follows: before the operation, according to operation wound size and the effect of strutting that wants, select the plectrum 6 of suitable quantity and select suitable mounted position, in the operation, electric handle 1 is being controlled, slowly stretch into the wound with plectrum 6, reach preset position after, continuously press and prop the key, when strutting the degree suitable, it does other corresponding operations to relieve and prop the key, the tiltability of plectrum 6, can make muscle and cortex and adipose layer strut the degree different, avoid muscle damage, the antiskid silica gel layer 62 of plectrum 6 outside can prevent to strut in-process muscle landing, avoid hindering the operation process, after other operations finish, continuously press and contract the key, treat after plectrum 6 folds up completely, take out the device again, suture the wound, the whole operation gets off, not only save medical personnel's physical power, the operation precision has still been improved, can also avoid the patient to have the secondary injury in the muscle struts in-process.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
