Problems solved by technology

However, it has been found in the application that although the pulling rope is wound on the slider with a plurality of pulleys, the pulling rope itself cannot When there is a tension difference between the two sides of the surgical incision, it will rotate precisely to counteract the tension, so that after the surgical incision is retracted and the field of view is exposed, there may still be a large tension difference on both sides, which can improve the condition of unilateral muscle over-extrusion not obvious

Embodiment 1

[0033] The number of the motor 12 in this embodiment is one and two output shafts of the motor 12 have a symmetric distribution. Such as figure 1 The motor 12 is disposed in the middle of the base 1, and the two output shafts of the motor 12 are distributed to the left and right side, and the horizontal distributed screw 10 is connected by the electromagnetic clutch 11, respectively. The left screw 10 is mounted with the filament 9 provided in the left slider 8, and the right screw 10 is mounted with a filament 9 disposed within the right slider 8. After the motor 12 is activated, in the electromagnetic clutch 11 engaged, the two slitters 8 are driven by two slitters 8 in reverse sliding along the strip 3. After any of the electromagnetic clutch 11, the output shaft of the motor 12 is disconnected from the torque between the corresponding screw 10, and the slider is stationary. In this embodiment, the motor 12 is integrated with a worm wheel box or other self-locking function, wh...

Embodiment 2

[0043] Such as image 3 As shown, the main structure and the retraction force balancing system in this embodiment are the same as those of Example 1. The difference is only that the number of motor 12 is two in this embodiment and the two motor 12 are disposed at both ends of the base 1. The two motor 12 outputs the axis relative distribution and is connected to one of the electromagnetic clutch 11, respectively. Two motor 12 share a control circuit to achieve synchronous opening and closing.

[0044] The method in which the method in this embodiment is the same as that of Example 1, and details are not described again.

Embodiment 3

[0046] Such as Figure 4 As shown, a muscle retracting device that can hold the holding force has a motor 12, and the motor 12 is disposed at the center of the susceptor 1 and has two synchronous output shafts that are distributed toward the left and right sides. Unlike Example 1, any of the output shafts in this embodiment is connected to the corresponding side lead bonds 10 by mutually independent first electromagnetic clutch 19 and the second electromagnetic clutch 20. In any of the first electromagnetic clutch 19 or the second electromagnetic clutch 20, it is possible to achieve a torque transmission between the output shaft and the screw 10; when the first electromagnetic clutch 19 and the second electromagnetic clutch 20 are separated. In the state, the output shaft and the screw 10 do not transfer torque.

[0047] The trailing force balancing system in this embodiment has a detecting mechanism for detecting the pull tension in which the hook 4 is tested and used to slide th...

Abstract

The invention discloses an asymmetric muscle retraction method and device. The method comprises the steps: respectively hanging retraction hooks on the skin at two sides of a surgical incision, respectively connecting retraction ropes at the rear ends of the retraction hooks to sliding blocks through tension sensors, and driving the two sliding blocks to slide oppositely; In the sliding process ofthe two sliding blocks, tension numerical values detected by the two tension sensors are uploaded to the single-chip microcomputer in real time, and the tension numerical values detected by the two tension sensors are judged through a comparison program arranged in the single-chip microcomputer. an electromagnetic clutch in the motor lead screw structure corresponding to the retracting hook on the side with the larger tension value is separated, so that the corresponding slide blocks corresponding to the retracting hook with a relatively high tension value can be in a standing state. According to the surgical incision retractor, the retraction force of the two retraction hooks is automatically balanced according to the stretching resistance of muscles on the two sides of a surgical incision, the asymmetric retraction effect relative to an original surgical incision is generated, and therefore excessive extrusion of muscular tissue on one side is avoided.

Description

Technical field [0001] The present invention relates to the field of general surgical equipment in the field, and in particular, a non-symmetrical muscle retraction method and apparatus. Background technique [0002] Muscle trailers are widely used in ordinary surgery, which is used to take the structure before surgery, reveal the surgical range, which is easy to explore and operate. Existing muscle retractors can be divided into two categories of hand-held hooks and automatic elimination, with specifications of different shapes and sizes, which can be selected according to the surgery. [0003] The muscle retractor of the hand-held hook is always required to hold the pull-up rope of the medical staff, but also consume a lot of physical strength, but also maintain the incision is extremely unstable, which is easy to cause improper operation during the operation. The exposed surgical incision is re-closed, affecting the procedure process. The automatic shocked muscle trailers are ...
