Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a dissecting knife for local adjustment of implanted breast augmentation. Background Technology

[0002] Breast augmentation is a common procedure in plastic surgery. By creating a cavity behind the pectoralis major muscle or breast tissue and inserting an implant, the volume of the breasts is significantly increased, resulting in a firmer and fuller appearance. Currently, with the improvement of people's economic level and the advancement of aesthetic awareness, more and more women hope to use this method to achieve their pursuit of beauty.

[0003] According to the public disclosure number CN 205126322 U, a separator for tunnel separation in breast augmentation surgery is described. The key technical points are: the separator described in this utility model adopts a structure similar to medical scissors. The separation part has a certain thickness and width, and the edges are smooth and rounded. The angle of the two dissecting heads can be adjusted to 90 degrees, so as to fix one side to strengthen the resistance and increase the force and accuracy of the dissecting head on the other side. It can protect the surrounding normal soft tissue while separating the cavity, forming an easy-to-separate cavity without causing serious tissue damage. It has the advantages of precise control of force, direction and range, which can speed up the breast augmentation surgery and improve the postoperative recovery speed.

[0004] The above-mentioned technology has the advantages of not causing serious tissue damage during dissection and achieving precise control over force, angle, and range. However, it still has some drawbacks. The structure used above produces relatively limited effects, and the blade design of the dissection knife is not flexible and precise enough to adapt well to different surgical sites and angle requirements. Especially when making local adjustments, the operation is not convenient and efficient enough. In view of this, we propose a new type of dissection knife for local adjustment of implant breast augmentation to solve the above problems. Utility Model Content

The rotating block is fixedly connected to the outer wall of the handguard. The slide rod is embedded through the front end surface of the rotating block. The two ends of the slide rod pass through the upper and lower end faces of the knife handle and are rotatably mounted with a rotating shaft. A stop shaft is sleeved on both sides of the outer surface of the slide rod, and the two stop shafts abut against the rotating block on the side closest to each other. A limiting spring is movably sleeved between the stop shaft and the rotating shaft.

[0010] Furthermore, the upper and lower end faces of the tool holder are provided with limiting holes, and the two limiting holes are in sliding contact with the slide rod.

[0025] The blade body mechanism 4 includes a blade post 401, a blade head 412, a limiting groove 402, a limiting post 403, a sleeve shaft 405, a tapered shaft 407, a limiting groove 406, a fixed shaft 410, and a locking block 414. The blade post 401 is fixedly connected to the left side wall of the handguard 3. The surface of the blade post 401 has a limiting groove 402, and the sleeve shaft 405 and the limiting post 403 are embedded in the limiting groove 402. The bottom of the sleeve shaft 405... A limiting groove 406 is provided on the side wall, and a limiting post 403 is inserted into the limiting groove 406. One end of the sleeve shaft 405 is fixedly connected to a tapered shaft 407, and a cavity is formed between the sleeve shaft 405 and the tapered shaft 407. A fixed shaft 410 is located in the cavity, and a cutter head 412 is fixedly connected to the top of the fixed shaft 410. A snap-fit ​​block 414 is provided on the outer wall of the fixed shaft 410, and the snap-fit ​​block 414 is fitted into the tapered shaft 407.

[0026] The cutter body mechanism 4 also includes a first screw 409, a second screw 411 and a mounting hole 408. Mounting holes 408 are provided on both sides of the cutter column 401. The first screw 409 is slidably disposed in the mounting hole 408. The second screw 411 is connected to the two side walls of the fixed shaft 410.
