The doctor can use the scalpel in general, and the holding method is four (as shown in fig. 5):

the first is: bow-holding method

The tool holding mode is the most commonly used one, the action range is wide and flexible, the force is applied to the whole upper limb, but the tool is mainly concentrated on the wrist and is mainly used for the incision with larger chest and abdomen.

The second is: pen holding method

The holding method has the advantages of light force, flexible and accurate operation, convenient control of the activity degree of the knife, and the action and the force of the knife are mainly in the fingers. Can be used for short incision and fine surgery, such as dissection of blood vessel, nerve and peritoneum.

The third is: gripping method

The knife handle is held by the full hand, and the thumb and the index finger tightly pinch the notch of the knife handle. The method has stable knife control. The main point of action is the shoulder joint. Can be used for operation with wide cutting range, deep incision position and large force requirement, such as amputation, tendon incision, etc.

The fourth is: reverse picking method

Is a conversion form of the pen-holding method, and the knife edge is upwards used for picking up the superficial skin, so that the deep tissues can be prevented from being damaged. The point of movement is the finger, which is commonly used for superficial abscess incision.

When medical staff performs surgery on a patient through a grasping method, the force is required to be high, so that uncomfortable symptoms can occur on hands of the medical staff when the surgical knife is used for a long time, and the problem is solved through the following structure.

As shown in fig. 1 to 4, a surgical knife convenient to grasp includes a handle body 100, a first grip 200 is provided at one side of the handle body 100, a second grip 300 is provided at the other side of the handle body 100, a cutter head 400 is provided at an end of the handle body 100, and a blade 500 is mounted on the cutter head 400; the outer wall of the tool handle main body 100 is provided with a trapezoid groove 110; the first holding piece 200 comprises a finger ring sleeve 210, a rotating disc 220, a connecting disc 230 and a trapezoidal sliding block 240, wherein the trapezoidal sliding block 240 is arranged in the trapezoidal groove 110, the connecting disc 230 is arranged at the end part of the trapezoidal sliding block 240, the rotating disc 220 is arranged at one end of the connecting disc 230 far away from the trapezoidal sliding block 240, and the finger ring sleeve 210 is arranged at one end of the rotating disc 220 far away from the connecting disc 230;

the finger ring 210 is made of rubber, so that the medical staff can feel more comfortable when using the finger ring; in order to facilitate the grasping by the medical staff, the rotating disc 220 is rotatably connected with the connecting disc 230;

the inner parts of the first grip 200 and the second grip 300 are identical except for the aperture size of the finger ring 210;

the above-mentioned structural design is convenient for medical personnel to adjust the position of first gripping member 200 and second gripping member 300 according to own demand, overlaps first gripping member 200 and second gripping member 300 respectively with forefinger and thumb when using the scalpel, can accomplish the gripping to the scalpel.

However, during the course of research and development experiments, the medical staff found that the positions of the first grip 200 and the second grip 300 are easily moved during use, and thus the above problems are solved by the following structure.

Referring to fig. 2, 3 and 4, the number of the trapezoid slots 110 is four, the trapezoid slots 110 of four groups are distributed on two sides of the tool shank main body 100, and the trapezoid slots 110 extend along the length direction of the tool shank main body 100;

the inner wall of the trapezoid groove 110 is provided with limiting holes 120 penetrating to the outer wall of the tool handle main body 100, and the limiting holes 120 are distributed in a square equidistant array according to the length of the trapezoid groove 110;

the first holding piece 200 further comprises a limiting rod 250 and a limiting magnetic plate 260, wherein the limiting magnetic plate 260 is connected with the connecting disc 230 through magnetic force, the limiting rod 250 is fixedly assembled on one side of the limiting magnetic plate 260, the number of the limiting rods 250 is three, and the three groups of limiting rods 250 are distributed on one side of the limiting magnetic plate 260 in an equidistant array manner;

one side of the connection disc 230 is provided with a first through hole penetrating to the other end of the connection disc, one side of the trapezoidal sliding block 240 is provided with a second through hole penetrating to the other end of the trapezoidal sliding block, and the apertures of the first through hole and the second through hole are matched with the outer wall of the limit rod 250;

the above-mentioned structural design is convenient for the medical personnel to pull out the limit magnetic plate 260 outwards when the position of the first holding piece 200 and the second holding piece 300 needs to be adjusted, so that the limit magnetic plate 260 moves to drive the limit rod 250 to move, when the limit rod 250 moves from the inside of the trapezoid slider 240 to be separated from the limit hole 120, the first holding piece 200 and the second holding piece 300 can slide, and when the first holding piece 200 and the second holding piece 300 move to the required position, the limit magnetic plate 260 is reset again, thus the locking of the first holding piece 200 and the second holding piece 300 can be completed.

The foregoing is only illustrative of the preferred embodiments of the present utility model, and is not intended to be exhaustive or to be construed as limiting the utility model to the precise forms disclosed. It should be understood that the above description is not intended to limit the utility model to the particular embodiments disclosed, but to limit the utility model to the particular embodiments disclosed, and that the utility model is not limited to the particular embodiments disclosed, but is intended to cover modifications, adaptations, additions and alternatives falling within the spirit and scope of the utility model.
