Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
This embodiment provides a new tendon cutter, as shown in fig. 1, 2, 3 and 5, comprising scissors,
the distance between the notch 1 and one end of the cutter head 2, which is far away from the handle of the scissors, is less than 5mm, specifically, 2mm in the embodiment;
when the scissors are closed, the two notches 1 are closed to form a loop taking port 3;
the outer sides of the two ends, far away from the scissor handle 4, of the knife heads 2 are arc-shaped.
The working principle of the technical scheme is as follows: the operation of taking the tendon of the arm as an example is similar to other operations.
Firstly, a minimally invasive incision is made in the skin on the upper part of a wrist tendon, and the tendon is found;
the right hand of the operator uses the novel tendon incision device of the embodiment to open the loop incision and uses the two notches 1 to clamp the tendon, and at the moment, the tendon can slide into the two notches 1 due to the characteristics of the tendon itself;
closing both of the notches 1, wherein a gap exists between the tendon and the extraction opening 3, thereby allowing the tendon to slide within the extraction opening 3;
the operator pulls the tendon out of the incision with the tendon cutter, and the operator pulls the tendon with his left hand, and operates the tendon cutter with his right hand to extend into the incision and move it toward the elbow, at which time the tendon slides in the insertion opening 3, thereby separating the tendon from its surrounding tissues;
when the cutting length is reached, the left hand of the operator pulls the tendon tightly, and the right hand operates the tendon cutter to open the scissor bit, at the moment, the tendon slides into the blade, and the right hand operates the tendon cutter to cut the tendon, so that the cut tendon in the arm can be drawn out.
The beneficial effects of the above technical scheme are: the scissors tool bit sets up notch 1 with tool bit 2 is kept away from the distance of scissors one end is less than 5mm, conveniently snatchs, separates the tendon, does not influence tissue around the tendon, and cuts the tendon behind the convenient separation tendon, and whole operation wound is little, and only a little incision can be accomplished, saves time.
In one embodiment, as shown in figures 1 and 2,
the device also comprises a limiting device, wherein the limiting device comprises a limiting rod 5 and a limiting hole 6;
the limiting rod 5 is arranged on the inner side of one scissor handle 4;
the limiting hole 6 is formed in the inner side of the handle of the other scissors handle 4;
when the limiting rod 5 extends into the limiting hole 6, the two notches 1 are closed.
The working principle of the technical scheme is as follows: in the last embodiment, the distance between the notch 1 and the end of the knife head 1 far away from the scissors is less than 5mm, and is very narrow, so that when an operator uses the novel tendon cutter, the operator cannot observe the condition of the knife head of the scissors extending into the arm, therefore, as shown in fig. 5, the end of the knife head far away from the scissors is easy to stagger due to different hand strength of the operator, so that tendons are tightly clamped by the notch 1, and the tendons cannot be smoothly separated, and pain is caused to a patient; or, the operator may worry about the above situation, and the two notches 1 are not closed and the distance between the two notches is too large, so that the tendon is easy to slip out from the two notches 1, and the operation difficulty is increased.
In the embodiment, the two handles of the scissors are provided with the limiting devices, and the handles are completely exposed under the visual field of an operator in the operation process, so that the operator can ensure that the two notches 1 extending into the arm of the patient are closed to form the proper extraction opening 3 by ensuring that the limiting rod 5 extends into the limiting hole 6, and the tendon can be conveniently separated.
The beneficial effects of the above technical scheme are: by providing a stop means, it is ensured that both said recesses 1 are closed, thereby forming a withdrawal opening 3.
In one embodiment, as shown in figure 3,
the plane of the sleeving and taking opening 3 and the plane of the cutting edge of the cutter head form an angle of 10-15 degrees, specifically, the angle is 12 degrees in the embodiment.
When the angle is within the range, the cutter head 2 of the convenient scissors extends into the incision and slides along the tendon to separate the tendon.
In one embodiment, as shown in figure 2,
the extraction opening 3 is oval.
When the angle is set according to the previous embodiment, the sleeving and taking port 3 is oval, so that the sleeving and taking port 3 can slide with the tendon more conveniently, and the tendon can be separated conveniently.
In one embodiment, as shown in figures 1 and 2,
As described in the first embodiment, when the surgeon uses the tendon cutter, the extraction opening 3 is inserted under the skin, so that the surgeon cannot easily determine the length of the separated tendon. However, when the scissors are provided with the scales 7, the surgeon can observe the length of the separated tendon according to the scales 7 provided on the scissors, thereby facilitating the cutting of the tendon of the desired length.
It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
