Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a device for extracting rib cartilage slices in vivo. Background Art

[0002] Costal cartilage is located on the side of the thorax. It is a soft and elastic tissue that is easier to cut and shape than other types of bone tissue. In some thoracic surgeries, it is necessary to obtain thin slices of costal cartilage to repair or rebuild damaged tissue structures. For example, for some breast reconstruction surgeries, thoracic repair surgeries or other similar surgeries, it is necessary to cut thin slices from the patient's ribs for use.

[0003] In the existing in vivo costal cartilage slice cutting equipment, the accuracy of cutting costal cartilage is largely limited by human factors, requiring doctors to maintain the same action for a long time. When the doctor's hand is unstable, the size and shape of the cut cartilage slice may not be satisfactory, thus affecting the success rate and effect of the operation. At the same time, it is also inconvenient to replace the cutting knife, which may cause greater trauma during the operation and increase the risk of postoperative complications.

[0004] How to invent a device for extracting rib cartilage slices in vivo to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0009] Preferably, the cutter is arranged to be inclined downward and its end portion extends to the outside of the limiting frame, and the outer end surface of the roller shaft extends below the bottom surface of the limiting frame.

[0010] Preferably, the cross section of the limit frame is U-shaped, and the limit frame is movably inserted into the two limit sleeves through a limit shaft.

[0011] Preferably, two ends of the adjusting screw are provided with two sections of reciprocating threads which are arranged in opposite directions to each other, and the two ends of the adjusting screw are respectively threadedly connected to the adjusting clamping parts.

[0012] Preferably, the thickness of the elastic portion is smaller than the thickness of the adjusting clamping portion, and the inner cavity side wall of the handle is provided with an anti-slip texture.

[0013] The beneficial effects of the utility model are:

[0023] Example

[0024] Reference Figure 1-Figure 3 , a device for in vivo cutting of rib cartilage slices, comprising a handle 1, an inner cavity of the handle 1 is slidably connected with an extension part 2, the end of the extension part 2 extends to the outside of the handle 1 and a limiting groove 201 is arranged at the end thereof, an adjusting component 3 is movably connected in the limiting groove 201, an upper end of the adjusting component 3 and a corresponding side wall of the extension part 2 are provided with a mounting hole, a connecting bolt 4 is movably inserted in the mounting hole, the end of the connecting bolt 4 extends to the outside of the extension part 2 and a locking nut 401 is threadedly connected thereto, the adjusting component 3 is composed of an elastic part 301 and an adjusting clamping part 302, an adjusting lead screw 5 and two limiting sleeves 6 are respectively arranged on the adjusting clamping part 302, the limiting sleeve 6 is located at the end of the adjusting clamping part 302, and a cutting component is movably arranged between the two limiting sleeves 6;

[0025] It should be noted that: two ends of the adjusting screw 5 are provided with two sections of reciprocating threads arranged in opposite directions to each other, and the two ends of the adjusting screw 5 are respectively threadedly connected with the adjusting clamping part 302, and the opening and closing degree of the adjusting component 3 can be controlled by twisting the adjusting screw 5, so as to clamp cutting components of different specifications, and the thickness of the elastic part 301 is smaller than the thickness of the adjusting clamping part 302, and the inner cavity side wall of the handle 1 is provided with anti-slip bottom lines, which increases the stability and safety when holding;

[0026] Reference Figure 3-Figure 4 The cutting assembly includes a limiting shaft 703 fixedly connected to the limiting frame 7 and the outer wall of the limiting frame 7, a cutter 701 is fixedly connected to the lower end of the inner wall of the limiting frame 7, and a roller shaft 702 is rotatably connected to the upper end of the inner wall of the limiting frame 7;

[0027] It should be noted that the cutter 701 is tilted downward and its end extends to the outside of the limit frame 7. The outer end surface of the roller shaft 702 extends below the bottom surface of the limit frame 7 to ensure that the patient's costal cartilage slices can be cut. The cross-section of the limit frame 7 is U-shaped, and the limit frame 7 is movably connected to the inside of the two limit sleeves 6 through the limit shaft 703, which is convenient for replacing the cutting component.

[0028] The working principle of the device for in vivo cutting of rib cartilage slices is as follows: the handle 1 is designed with an inner cavity for sliding connection of the extension part 2, allowing the extension part 2 to be accurately adjusted forward and backward in the handle 1, so that the doctor can control the extension length of the extension part 2 according to the surgical requirements, and by accurately controlling the cutting depth and range, the required cartilage can be obtained from the rib without destroying its overall structure. The inner cavity side wall of the handle 1 is provided with an anti-slip bottom pattern, which increases the stability and safety when holding;

[0029] The design of the limit frame 7, the cutter 701 and the roller 702 makes the cutting process stable and accurate. The inclined design of the cutter 701 helps to reduce damage to surrounding tissues. The cutter 701 can be supported during operation and the stability of the cutter 701 during the cutting process is ensured by the setting of the limit frame 7 and the roller 702 with a U-shaped cross section. The movable plug-in structure of the limit shaft 703 and the limit sleeve 6 allows the cutting assembly to be adjusted within a certain range according to the inclination angle of the operator holding the handle 1.

[0030] When the surgical area is not convenient for direct operation, the locking nut 401 can be loosened by rotating it counterclockwise, and the cutting angle can be adjusted. The adjustment can be adaptively performed according to the surgical area. After the adjustment is completed, it can be fixed again.

[0031] The adjusting screw 5 is designed with two sections of reverse threads, which allows the opening and closing of the clamping part 302 to be adjusted by rotating the screw. Then, the doctor can replace the cutting assembly suitable for the size of the patient's incision as needed. By minimizing the cutting range and providing precise operation, the instrument helps to reduce the risks of hematoma, pneumothorax, etc. that may occur during surgery, while reducing postoperative pain and improving patient comfort.

[0032] Overall, this design focuses on providing an adjustable, stable and precise way to cut thin slices of rib cartilage, which is crucial for surgeries such as repairing nasal deformities or other surgeries that require cartilage transplants. The design of this instrument helps simplify the surgical steps, allowing doctors to obtain rib cartilage slices more easily and quickly, reducing the difficulty of the operation and speeding up the overall surgical process.
