Description

Technical Field

[0001] This utility model relates to the field of rhinoplasty technology, specifically a rib cartilage carving plate. Background Technology

[0002] Rhinoplasty is a procedure that alters the height and shape of the nose by implanting appropriate materials to harmonize it with other facial features. It is one of the most common procedures in the field of plastic surgery.

[0003] In medicine, there are many types of materials used in rhinoplasty, such as medical-grade silicone rubber, autologous cartilage, animal tendons or ligaments, expanded polytetrafluoroethylene (ePTFE), and hyaluronic acid. There are also various methods for preparing nasal implants. Among them, autologous cartilage, because it comes from the patient's own body, does not cause rejection and has become the mainstream implant material. Before implanting rib cartilage, a layer of fascia needs to be sutured onto it to increase skin thickness. The fascia needs to be sutured around the rib cartilage, but currently there is no device specifically designed for suturing the rib cartilage fascia. Doctors must adjust the position of the rib cartilage multiple times before suturing, which is very inconvenient. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a rib cartilage carving plate to solve the shortcomings of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a rib cartilage carving plate, including a carving plate, a first positioning pin and a second positioning pin, wherein the first positioning pin and the second positioning pin are spaced apart along the length of the carving plate, the first positioning pin is vertically fixed on the carving plate, and the second positioning pin is slidably disposed on the carving plate, the second positioning pin having the freedom to move along the length of the carving plate, and the first positioning pin and the second positioning pin are respectively pierced at both ends of the rib cartilage to keep the rib cartilage in a suspended state.

[0006] Furthermore, a slider is fixed to the bottom of the second positioning pin, and a groove is formed on the top of the engraving plate along its own length direction, and the slider slides and adapts to the groove.

[0007] Furthermore, a threaded hole is provided on one side of the slider, and a strip groove is provided on the side wall of the engraving plate. The strip groove is connected to the slide groove, and the tail of the fastening bolt passes through the strip groove and is threaded into the threaded hole. The head of the fastening bolt abuts against the side wall of the engraving plate.

[0008] Furthermore, an elastic plate is fitted onto the fastening bolt, and the elastic plate is located between the head of the fastening bolt and the engraving plate.

[0009] Furthermore, both the first and second positioning pins are fixed with protrusions.

[0010] Furthermore, a first protective sleeve is movably fitted on the first positioning pin, and the first protective sleeve is threadedly connected to the engraving plate. A second protective sleeve is movably fitted on the second positioning pin. An annular threaded hole is opened at the top of the slider, and the bottom thread of the second protective sleeve is adapted to fit into the annular threaded hole.

[0011] The beneficial effects of this utility model are:

[0012] The costal cartilage is suspended and fixed by the first and second positioning pins, leaving the costal cartilage exposed around its perimeter. This facilitates fascia suturing around the costal cartilage, making the suturing operation easier for the doctor, reducing the difficulty of suturing, and improving suturing efficiency.

[0017] Example 1

[0018] like Figures 1 to 3 As shown, a rib cartilage carving plate includes a carving plate 1, a first positioning pin 2, and a second positioning pin 3. The first positioning pin 2 and the second positioning pin 3 are spaced apart along the length of the carving plate 1. The first positioning pin 2 is vertically fixed to the carving plate 1, while the second positioning pin 3 is slidably disposed on the carving plate 1, having the freedom to move along the length of the carving plate 1. The first positioning pin 2 and the second positioning pin 3 are respectively inserted at both ends of the rib cartilage to suspend the rib cartilage. By suspending and fixing the rib cartilage with the first positioning pin 2 and the second positioning pin 3, the rib cartilage is exposed around its perimeter, facilitating fascia suturing around the rib cartilage, simplifying the suturing operation, reducing the difficulty of suturing, and improving suturing efficiency. The position of the second positioning pin 3 is adjustable, allowing adjustment of the distance between the first positioning pin 2 and the second positioning pin 3 to accommodate different lengths of implanted rib cartilage. In specific implementation, the carving plate 1 is 6 cm long and 3 cm wide.

[0019] Example 2

[0020] Based on Example 1, such as Figure 1 As shown, both the first positioning pin 2 and the second positioning pin 3 are fixed with protrusions 10. The protrusions 10 support the costal cartilage and prevent it from being punctured and falling onto the carving plate 1 during the suturing process, so that the suspended position of the costal cartilage is not affected during the carving process.

[0021] Example 3

[0022] Based on Example 2, such as Figure 3 As shown, a first protective sleeve 11 is movably sleeved on the first positioning pin 2, and the first protective sleeve 11 is threadedly connected to the engraving plate 1. A second protective sleeve 12 is movably sleeved on the second positioning pin 3. The top of the slider 4 has an annular threaded hole, and the bottom thread of the second protective sleeve 12 is adapted to fit into the annular threaded hole. After use, the first protective sleeve 11 and the second protective sleeve 12 are respectively put on the first positioning pin 2 and the second positioning pin 3 to cover the first positioning pin 2 and the second positioning pin 3 and avoid puncture.

[0023] Example 4

[0024] Based on Example 3, such as Figure 1 and Figure 2 As shown, a slider 4 is fixed to the bottom of the second positioning pin 3. A groove 5 is formed on the top of the engraving plate 1 along its length. The slider 4 slides within the groove 5. A threaded hole 6 is formed on one side of the slider 4. A strip groove 7 is formed on the side wall of the engraving plate 1, which connects to the groove 5. The tail of the fastening bolt 8 passes through the strip groove 7 and is threaded into the threaded hole 6. The head of the fastening bolt 8 rests against the side wall of the engraving plate 1. An elastic piece 9 is fitted on the fastening bolt 8, located between the head of the fastening bolt 8 and the engraving plate 1. The first positioning pin 2 and the second positioning pin 3 are adjusted according to the size of the rib cartilage. To adjust the position of the second positioning pin 3, first loosen the fastening bolt 8 to unlock the movement freedom of the slider 4, allowing the slider 4 to move within the groove 5. During the movement of the slider 4, the fastening bolt 8 moves synchronously within the strip groove 7 to avoid interference. After adjustment, tighten the fastening bolt 8 so that the head of the fastening bolt 8 presses against the elastic sheet 9, causing deformation and thus pressing the fastening bolt 8 against the engraving plate 1, preventing the fastening bolt 8 from moving. This restricts the movement freedom of the slider 4, fixing the position of the second positioning pin 3. The operation is simple and has a wide range of applications.
