AI Technical Summary
In surgical procedures, the flap needs to be peeled through the small incision buried dilator. The peeled skin tissue is arc-shaped in the cross-section. When peeling the deep flap, the tissue near the incision protrudes on the cross-section. The straight shank cannot enter the peeling position through the small incision, and the required uniform thickness flap cannot be peeled out.
An adjustable curvature scalpel handle is designed, including a blade, a blade mount, a handle body, a block, a screw, a knob and two steel ropes. The tension of the steel rope is adjusted by twisting the knob, thereby bending and adjusting the shape of the handle body to adapt to the arc of the subcutaneous tissue.
The adjustable bend of the tool holder body is realized, and it can be adjusted according to the protruding arc of the subcutaneous tissue, thereby solving the problem that the straight tool holder cannot enter the peeling position and ensuring that the flap of uniform thickness can be peeled out.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.
[0018] Please refer to Figures 1 to 6 , Figure 1 which is a schematic structural diagram of the adjustable curvature surgical knife handle of the present utility model, Figure 2 which is a partial structural diagram of the present utility model, Figure 3 which is a schematic structural diagram of the screw of the present utility model, Figure 4 which is a schematic structural diagram of the block of the present utility model, Figure 5 which is a top view of the block of the present utility model, Figure 6 which is a schematic structural diagram of the capsule body of the present utility model. The present utility model provides an adjustable curvature surgical knife handle: including a blade 1, a blade 1 mounting member, a handle main body 2, a support block 3, a screw 4, a knob 5 and two steel cables 6. The blade 1 mounting member and the support block 3 are both arranged on the handle main body 2. The blade 1 is mounted on the blade 1 mounting member. The screw 4 is fixedly connected to the support block 3. The knob 5 is in threaded cooperation with the support block 3. The handle main body 2 includes a plurality of blocks 7 and a plurality of capsule bodies 8. The block 7 is provided with two arc grooves 16. A plurality of capsule bodies 8 are respectively placed in the corresponding arc grooves 16. The block 7 is provided with two first round holes 14. The capsule body 8 is provided with two second round holes 15. One ends of the two steel cables 6 are both fixedly connected to the blade 1 mounting member. The other ends of the two steel cables 6 respectively pass through a plurality of corresponding first round holes 14 and second round holes 15 in sequence and are slidably connected to the screw 4. And the two steel cables 6 are both connected to the knob 5;
[0019] The knob 5 includes a threaded sleeve 9 and a rotating member. The threaded sleeve 9 is in threaded cooperation with the screw 4. The rotating member is fixedly connected to the threaded sleeve 9. And the two steel cables 6 are both fixedly connected to the rotating member.
[0020] In this embodiment, during specific use, when it is necessary to bend the handle body 2, only need to turn the knob 5 according to actual requirements. At this time, the threaded sleeve 9 of the knob 5 rotates on the screw rod 4. At this time, the two steel ropes 6 are in a relaxed state. Then bend the handle body 2, and several blocks 7 and several capsule bodies 8 on the handle body 2 come into contact respectively to form a specified bending angle. After the adjustment is completed, turn the knob 5 in the reverse direction. The threaded sleeve 9 on the knob 5 moves away from the screw rod 4 to generate a relative displacement therewith. At this time, the knob 5 drives the two steel ropes 6 to move, so that the two steel ropes 6 slide in the corresponding first round holes 14 and the corresponding second round holes 15 respectively until the steel ropes 6 are in a taut state, thus completing the support of the handle body 2 and the adjustment of the bending degree of the handle body 2. In this way, it solves the technical problem in the prior art that in surgical operations, when implanting a dilator through a small incision, it is necessary to strip the skin flap. The stripped skin tissue is arc-shaped in cross-section. When stripping the deep skin flap, the tissue near the incision bulges in cross-section. A straight handle cannot enter the stripped position through a small incision, and a skin flap with a required uniform thickness cannot be stripped. The curved handle body 2 can be adjusted to the corresponding curvature of the handle body 2 according to the curvature of the subcutaneous tissue bulge.
[0021] Furthermore, the rotating member includes a rotating rod 10 and two support ears 11. The rotating rod 10 is fixedly connected to the threaded sleeve 9, and the two support ears 11 are both fixedly connected to the rotating rod 10.
[0022] In this embodiment, through the two support ears 11 of the knob 5, the two support ears 11 drive the rotating rod 10 to rotate to drive the threaded sleeve 9 to rotate.
[0023] Furthermore, the blade 1 mounting member includes a connecting block 12 and a blade card slot 13. The connecting block 12 is fixedly connected to the corresponding capsule body 8, the blade card slot 13 is connected to the connecting block 12, and the blade 1 is arranged in the blade card slot 13.
[0024] In this embodiment, the blade card slot 13 is connected to the handle body 2 through the connecting block 12, and the blade card slot 13 is used for mounting the blade 1.
[0025] Advantages of the present utility model: When it is necessary to bend the handle main body 2 during specific use, only need to turn the knob 5 according to actual requirements. At this time, the threaded sleeve 9 of the knob 5 rotates on the screw rod 4, and at this time, the two steel ropes 6 are in a relaxed state. Then bend the handle main body 2, and several blocks 7 and several capsule bodies 8 on the handle main body 2 contact respectively to form a specified bending angle. After the adjustment is completed, turn the knob 5 in the reverse direction. The threaded sleeve 9 on the knob 5 moves away from the screw rod 4 to generate a relative displacement therewith. At this time, the knob 5 drives the two steel ropes 6 to move, so that the two steel ropes 6 slide in the corresponding first round holes 14 and the corresponding second round holes 15 respectively until the steel ropes 6 are in a taut state, which completes the support for the handle main body 2 and the adjustment of the bending degree of the handle main body 2. In this way, it solves the technical problem in the prior art that during a surgical operation, when a dilator is buried through a small incision, it is necessary to strip the skin flap. The stripped skin tissue is arc-shaped in cross-section. When stripping the deep skin flap, the tissue near the incision bulges in cross-section, and a straight handle cannot enter the stripped position through the small incision, and a skin flap with a required uniform thickness cannot be stripped. The curved handle main body 2 can be adjusted to the corresponding curvature of the handle main body 2 according to the curvature of the subcutaneous tissue bulge.
[0026] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of rights of the present utility model. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
