Elastic fast strutting device for abdominal surgery cut

Abstract

The invention discloses an elastic fast stretching device for abdominal surgery incision, which comprises two symmetrical and hinged left and right driving rods, the head and tail of the four stretching and retracting rods are respectively hinged together through rotating shafts to form a rhombus structure. A linear bearing or a sliding sleeve is set on the retracting rod, and a rotary sleeve or a smooth shaft is vertically connected to one side of the linear bearing or the sliding sleeve; an elastic adjustment mechanism is arranged between the left and right driving rods. In the present invention, after the four expansion and contraction rods of rhombus structure are compressed, each linear bearing or sliding sleeve can shrink to the center, so that the distance between the four rotating sleeves is small and can be smoothly inserted into the incision. During the unfolding process of each retractable rod, the linear bearing or sliding sleeve can automatically slide and finally maintain a square distribution. The operation is convenient and the effect is good.

Description

Technical field [0001] The invention belongs to the technical field of clinical surgical incision expanders, and in particular relates to an elastic and rapid expansion device for abdominal surgical incisions. Background technique [0002] At present, multiple retractors are used in general surgical operations to pull open the surgical incision to expand the field of vision and facilitate medical operations, which requires the cooperation of multiple medical staff. The shortcomings of the retracting operation are obvious, and the medical staff is prone to fatigue for a long time, which brings inconvenience to the operation. The incision expansion device used in the prior art uses general forceps to clamp the incision and then opens the incision. The defect is that the surgical application is not compatible, especially for small incisions, which makes it more inconvenient to open the incision. It is easy to cause incision damage, affect the effect of the operation, extend the ope...

AI Technical Summary

Problems solved by technology

The disadvantages of adopting the hook-type stretching operation are obvious, and the medical staff are prone to fatigue for a long time, which brings inconvenience to the operation

The incision stretching instrument adopted in the prior art is to use general forceps to clamp the incision and then open it outwards. Its defect is that the operation application is not matched, especially for small incisions, and it is even more inconvenient to open the incision. It is easy to cause incision damage, affect the effect of surgery, prolong the operation time, and cannot meet the ideal surgical effect

[0003] In order to solve the above problems, there has been a spreader that is positioned by pulling and locking at both ends. This kind of spreader can adjust the spread width according to the size of the surgical incision, and does not need to be held by medical staff for a long time, but its shortcomings are: When the two ends are pulled outward, it is easy to spread too much due to inconvenient operation, causing damage to the surgical incision; when the hooks at both ends support the edge of the incision, the support force is insufficient, causing the spreader to fall, and the opening of the support is reduced, which affects Surgical operation

Although the left and right sliders form an opening, the pulleys at both ends shrink instead. If the square or rectangle formed by the four pulleys is smaller than the size of the incision, it will cause slack and fail to achieve an effective expansion effect.

And this two pliers handle is not easy to fix, troublesome to operate
