Description

Technical Field

[0001] The present invention relates to the field of maxillofacial surgery medical aesthetic tools, and in particular to a rib cartilage rhinoplasty auxiliary tool. Background Art

[0002] Costal cartilage rhinoplasty is a cosmetic surgery that uses autologous costal cartilage as a material for rhinoplasty. Figure 1 As shown, the patient's own costal cartilage is harvested and reshaped. The reshaped costal cartilage is then surgically attached to the nasal septum. The septal cartilage and costal cartilage are then sutured at multiple points to support the columella. Next, the bilateral alar cartilages are lifted and aligned with the fixed costal cartilage to form the high point of the nasal tip, which is then sutured.

[0003] In their work, the applicant discovered that existing nasal septum suturing methods have several inconveniences. For example, since the suturing is performed within the nasal cavity, the operation is not convenient. Poor fixation often leads to inaccurate suture points, affecting the suturing effect. Furthermore, the need for a dedicated person to lift the alar cartilage and fix the rib cartilage is also inconvenient.

[0004] Currently, there is no application of costal cartilage rhinoplasty auxiliary tools that solve the above problems. After searching, no patents that can solve the above problems were found. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a costal cartilage rhinoplasty auxiliary tool which makes nasal septum suturing more convenient and accurate.

[0006] The technical solution adopted to solve the above problems is as follows: the rib cartilage rhinoplasty auxiliary tool includes a clamping clamp, a clamp, a clamp mounting strip, a guide column and a height adjustment structure; the clamping clamp includes two clamping clamp handles arranged crosswise and hingedly, the front end of the clamping clamp handle is a first clamping clamp rod; the clamp mounting strip is arranged in a one-to-one correspondence with the clamping clamp handle and is located above the front of the clamping clamp handle, the front end of the clamp mounting strip is a second clamping clamp rod, and the second clamping clamp rod is parallel to the first clamping clamp rod; each clamping clamp handle is connected to two guide columns arranged at intervals in the front-to-back direction, and the clamp mounting strip is mounted on the guide columns so that it can move up and down; the height adjustment structure is connected to the clamping clamp handle, and the height adjustment structure can fix the clamp mounting strip and adjust the height of the clamp mounting strip; the clamp includes an elastic member and at least three clamping clamp units, each clamping clamp unit is arranged in the vertical direction, and the clamping clamp unit has a suture positioning hole, the elastic member connects adjacent clamping clamp units, the clamping clamp unit located at the bottom is connected to the first clamping clamp rod, and the clamping clamp unit located at the top is connected to the second clamping clamp rod.

[0007] Furthermore, the elastic member is a curved elastic sheet, and the width of the elastic sheet is greater than its thickness.

[0008] Furthermore, the clip unit is made of plastic, and the elastic member is made of steel.

[0009] Furthermore, the clip includes four clip units.

[0010] Furthermore, the clip is mounted on the first clip rod and the second clamping rod and is interference fit with the first clip rod and the second clamping rod. Each first clip rod and the second clamping rod can be mounted with multiple clips, and each clip unit has a suture positioning hole.

[0011] Furthermore, the height adjustment structure includes an adjusting bolt and a linkage piece, the adjusting bolt passes through a clip mounting strip and is threadedly connected to the clamping handle corresponding to the clip mounting strip, and positioning flanges are provided on both sides of the clip mounting strip on the adjusting bolt, and the positioning flanges are in contact with the clip mounting strip; the linkage piece is connected to the clip mounting strip through which the adjusting bolt passes, and the linkage piece has a long slot, and another clip mounting strip passes through the long slot, and the upper and lower walls of the long slot are in contact with the clip mounting strip.

[0012] Furthermore, the costal cartilage rhinoplasty auxiliary tool includes an anti-opening buckle. When the clip is clamped, the anti-opening buckle can connect the rear ends of the two clamping handles to prevent the clip from loosening.

[0013] The beneficial effect of the present invention is as follows: when the present invention is used, the surgeon assists the operator in placing the clips of the rib cartilage rhinoplasty auxiliary tool on the nasal septum with the rib cartilage supported, and then lightly pinches the clamping forceps to make the clips lightly clamp the nasal septum and fix the rib cartilage. The surgeon then uses a suture needle and thread to pass through the suture positioning hole to suture and fix the nasal septum cartilage and the rib cartilage. Finally, the front end of the rib cartilage rhinoplasty auxiliary tool is respectively placed into the bilateral nostrils, and the height adjustment structure is operated to raise the clips. The clips support the bilateral alar cartilages and the shaped nasal septum to form a new nasal tip high point. The clamping forceps are lightly pinched to fix the entire columella, which has the effect of lifting the bilateral alar cartilages in the prior art. Then the surgeon uses a suture needle and thread to suture and fix the nasal tip high point.

[0014] The invention is used to assist in suturing the nasal septum, which can lightly clamp and fix the nasal septum and avoid displacement of the inserted costal cartilage; passing the suture needle and thread through the suture positioning hole to suturing the nasal septum can ensure the accuracy of the suture point and avoid the suture points being too concentrated or dispersed, thus helping to ensure the suture effect. The clip supports the nasal cavity, playing the role of clamping the nasal cavity and pulling it up in the existing technology, so there is no need to clamp the nasal cavity and pull it up, which can simplify the operation to a certain extent. The structure of the clip determines that when the clip is raised, the elastic part rebounds, causing the distance between each clip monomer to increase evenly, that is, the distance between each suture positioning hole increases evenly, thereby further ensuring the uniformity of the suture points.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 2 to 7 As shown, the rib cartilage rhinoplasty auxiliary tool includes a clamping forceps 1, a clip 3, a clip mounting strip 2, a guide column 5 and a height adjustment structure 4; the clamping forceps 1 includes two clamping forceps handles 11 arranged crosswise and hingedly connected, the front end of the clamping forceps handle 11 is a first clamping plate rod 111; the clip mounting strip 2 is arranged in a one-to-one correspondence with the clamping forceps handle 11 and is located above the front part of the clamping forceps handle 11, the front end of the clip mounting strip 2 is a second clamping plate rod 21, and the second clamping plate rod 21 is parallel to the first clamping plate rod 111; each clamping forceps handle 11 is connected to two guide columns 5 spaced apart in the front and rear directions, The clip mounting strip 2 is mounted on the guide column 5 so that it can move up and down; the height adjustment structure 4 is connected to the clamping handle 11, and the height adjustment structure 4 can fix the clip mounting strip 2 and adjust the height of the clip mounting strip 2; the clip 3 includes an elastic member 32 and at least three clip monomers 31, each clip monomer 31 is arranged in the up and down direction, and a suture positioning hole 311 is provided on the clip monomer 31. The elastic member 32 connects adjacent clip monomers 31, and the clip monomer 31 located at the bottom is connected to the first clip rod 111, and the clip monomer 31 located at the top is connected to the second clamping sheet rod 21.

[0026] When the present invention is used, the surgeon assists the operator in placing the clips 3 of the costal cartilage rhinoplasty auxiliary tool on the nasal septum with the costal cartilage supported, and then lightly pinches the clamping forceps 1 so that the clips 3 lightly clamp the nasal septum and fix the costal cartilage. The surgeon then uses a suture needle and thread to pass through the suture positioning hole 311 to suture and fix the nasal septum cartilage and the costal cartilage. Finally, the front end of the costal cartilage rhinoplasty auxiliary tool is respectively placed into the bilateral nostrils, and the height adjustment structure 4 is operated to raise the clips 3. The clips 3 support the bilateral alar cartilages and the shaped nasal septum to form a new nasal tip high point. Lightly pinch the clamping forceps 1 to fix the entire nasal columella, thereby achieving the effect of lifting the bilateral alar cartilages in the prior art, and then the surgeon uses a suture needle and thread to suture and fix the nasal tip high point.

[0027] The invention assists in suturing the nasal septum, which can gently clamp and fix the nasal septum and prevent displacement of the inserted costal cartilage; passing the suture needle and thread through the suture positioning hole 311 to suturing the nasal septum can ensure the accuracy of the suture point and avoid the suture points being too concentrated or dispersed, thereby ensuring the suture effect. The clip 3 supports the nasal cavity, playing the role of clamping the nasal cavity and pulling it up in the existing technology, so there is no need to clamp the nasal cavity and pull it up, which can simplify the operation to a certain extent. The structure of the clip 3 determines that when the clip 3 is raised, the elastic member 32 rebounds, causing the distance between each clip monomer 31 to increase uniformly, that is, the distance between each suture positioning hole 311 increases uniformly, thereby further ensuring the uniformity of the suture points.

[0028] As previously mentioned, one function of the elastic member 32 is to rebound, thereby uniformly increasing the distance between the clip elements 31. Another function of the elastic member 32 is to connect the clip elements 31. The elastic member 32 should be able to elastically deform in the vertical direction, but should not easily deform in the horizontal direction. Therefore, in the present invention, the elastic member 32 is preferably a curved elastic sheet, with a width greater than its thickness. Furthermore, it is preferred that the clip elements 31 be made of plastic, and the elastic member 32 be made of steel.

[0029] According to the number of suture points generally required in the up-down direction, the clip 3 preferably includes four clip units 31 .

[0030] The connection method between the clip 3 and the first clip rod 111 and the second clamping rod 21 is preferably as follows: the clip 3 is mounted on the first clip rod 111 and the second clamping rod 21 and is interference fit with the first clip rod 111 and the second clamping rod 21. Multiple clips 3 can be mounted on each first clip rod 111 and the second clamping rod 21, and each clip unit 31 has a suture positioning hole 311.

[0031] In this way, different numbers of clips 3 can be installed according to the depth of the suture. If the suture position needs to be deeper, the number of clips 3 can be increased, and vice versa. The amount of interference fit between the clip 3 and the first clip rod 111 and the second clamping rod 21 should be appropriate to prevent the clip 3 from being difficult to put on and easy to move. When the present invention is used, the clip 3 is subjected to very little force in the forward and backward direction. Therefore, the clip 3 is installed on the first clip rod 111 and the second clamping rod 21, and the interference fit between the first clip rod 111 and the second clamping rod 21 can meet the requirements.

[0032] like Figure 6 and Figure 7 As shown, it is preferred that the uppermost suture positioning hole 311 of the rearmost clip 3 is a C-shaped hole, and the other suture positioning holes 311 are round holes. The reason is that the costal cartilage and the nasal septum are sometimes fixed with an additional stitch at the C-shaped hole.

[0033] The specific structure of the height adjustment structure 4 is preferably as follows: the height adjustment structure 4 includes an adjusting bolt 41 and a linkage piece 42, the adjusting bolt 41 passes through a clip mounting strip 2 and is threadedly connected to the clamping handle 11 corresponding to the clip mounting strip 2, and the adjusting bolt 41 is provided with positioning flanges 411 on both sides of the clip mounting strip 2, and the positioning flanges 411 are in contact with the clip mounting strip 2; the linkage piece 42 is connected to the clip mounting strip 2 through which the adjusting bolt 41 passes, and the linkage piece 42 has a long groove 421, and another clip mounting strip 2 passes through the long groove 421, and the upper and lower walls of the long groove 421 are in contact with the clip mounting strip 2.

[0034] Due to the guiding effect of the guide column 5, the clip mounting strip 2 can only move up and down. Rotate the adjusting bolt 41 to move it upward, and the positioning flange 411 will drive one clip mounting strip 2 to move upward. At the same time, the clip mounting strip 2 drives the linkage piece 42 to move upward, and the linkage piece 42 moves upward and drives the other clip mounting strip 2 to move upward. Therefore, when the height adjustment structure 4 adjusts the height of the clip mounting strip 2, it only needs to rotate the adjusting bolt 41, which is easy to operate. The clip mounting strip 2 that does not pass through the adjusting bolt 41 passes through the long slot 421, such as Figure 5 and Figure 8 As shown, the long slot 421 should be arranged in the left-right direction, which is to leave enough space for the clamp mounting strip 2 to swing, so as to avoid interference between the clamp mounting strip 2 and the linkage piece 42 when loosening or tightening the clamp 1.

[0035] To ensure that the costal cartilage rhinoplasty auxiliary tool maintains its grip after lightly clamping the nasal septum, the costal cartilage rhinoplasty auxiliary tool preferably includes an anti-opening buckle 6. When the clip 3 is clamped, the anti-opening buckle 6 can connect the rear ends of the two clamping forceps handles 11 to prevent the clip 3 from loosening. Many existing medical forceps have an anti-opening structure, and the specific structure of the anti-opening buckle 6 can be designed with reference to existing technologies.
