Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an ultrasonic knife central rod provided with an expansion structure. Background Art

[0002] The ultrasonic scalpel is a surgical energy platform based on ultrasound. It can stop bleeding by cutting some tissues locally. It can also provide some cosmetic techniques based on the ultrasonic scalpel to lift the face and remove wrinkles. A center rod is provided in the middle of the knife holder below the moving knife arm of the ultrasonic scalpel.

[0003] However, the center rod of the existing ultrasonic knife is relatively fixed, which makes it inconvenient to adjust the expansion, resulting in a single usage.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and an ultrasonic knife center rod with an expansion structure is provided. Utility Model Content

[0005] The purpose of the utility model is to provide an ultrasonic knife center rod with an expansion structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultrasonic knife center rod with an expansion structure, comprising a bottom rod and an adjustment component, an adjustment plate is arranged on the left side of the bottom rod, and a mounting hole is opened on the surface of the bottom rod, the adjustment component for expansion adjustment is arranged on the outside of the adjustment plate, and the adjustment component comprises a limit groove, an adjustment block, an expansion plate and a sealing plate, an adjustment block is slidably installed inside the limit groove, and an expansion plate is installed at the end of the adjustment block, and a sealing plate is installed at the end of the expansion plate.

[0007] Furthermore, the left side of the expansion plate is connected to a connection platform, and the left side of the connection platform is connected to a pole top.

[0008] Furthermore, a connecting block is provided on the surface of the adjusting piece, and a connecting rod is installed at the end of the connecting block.

[0009] Furthermore, five connecting blocks are equidistantly distributed about the connecting rod, and two groups of connecting blocks and connecting rods are provided.

[0010] Furthermore, the right end of the connecting rod is connected to a cover, and a folding hole is opened inside the bottom of the cover.

[0011] Furthermore, a hydraulic gas rod is installed inside the folding hole, and the folding hole and the cover are an integrated structure.

[0012] Furthermore, the side of the cover is provided with auxiliary components for auxiliary adjustment, and three groups of auxiliary components are provided.

[0013] Furthermore, the auxiliary component includes an auxiliary sleeve and an anti-deviation rod, and the anti-deviation rod is arranged inside the auxiliary sleeve.

[0014] The utility model provides an ultrasonic knife center rod with an expansion structure, which has the following beneficial effects:

[0015] 1. The utility model uses the limiting groove to limit the movement of the adjustment block to avoid the expansion plate from moving offset during expansion. The adjustment sheet moves inside the expansion plate so that the adjustment sheet can move for expansion, increasing the large diameter of the center rod. The sealing sheet itself can be stretched, thereby increasing the sealing between the expansion plate and the adjustment sheet, avoiding leakage of the center rod during expansion.

[0016] 2. The utility model uses a connecting block to place the connecting rod in the middle of the adjusting plate so that the adjusting plate can be evenly stressed. The hydraulic gas rod drives the connecting rod to move outward with respect to the center of the center rod through telescoping. The connecting rod drives the adjusting plate to move in an expanding manner to complete the expansion of the center rod. The cover serves as an outer cover for the hydraulic gas rod. When the auxiliary sleeve moves outside the anti-deviation rod, the movement and adjustment of the auxiliary cover are adjusted, thereby increasing the stability of the movement of the connecting rod.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1As shown, an ultrasonic knife center rod with an expansion structure includes a bottom rod 1 and an adjustment component 4, an adjustment plate 2 is arranged on the left side of the bottom rod 1, and a mounting hole 3 is opened on the surface of the bottom rod 1, a connecting platform 5 is connected to the left side of the expansion plate 403, and a rod top 6 is connected to the left side of the connecting platform 5, a connecting block 7 is arranged on the surface of the adjusting plate 2, the connecting block 7 makes the connecting rod 8 in the middle of the adjusting plate 2 so that the adjusting plate 2 can be evenly stressed, and a connecting rod 8 is installed on the end of the connecting block 7, five connecting blocks 7 are equidistantly distributed about the connecting rod 8, and two groups of connecting blocks 7 and connecting rods 8 are arranged, the connecting rod 8 drives the adjusting plate 2 to move for expansion, and completes the expansion of the center rod.

[0023] like Figure 2 As shown, the adjustment component 4 for expansion adjustment is arranged on the outside of the adjustment piece 2, and the adjustment component 4 includes a limit groove 401, an adjustment block 402, an expansion plate 403 and a sealing sheet 404. The adjustment block 402 is slidably installed inside the limit groove 401. The limit groove 401 allows the adjustment block 402 to limit and adjust the movement to avoid the expansion plate 403 from moving offset during expansion. The adjustment piece 2 moves inside the expansion plate 403, so that the adjustment piece 2 can move for expansion, increasing the large diameter of the center rod, and the expansion plate 403 is installed at the end of the adjustment block 402. The sealing sheet 404 is installed at the end of the expansion plate 403. The sealing sheet 404 itself can be stretched, thereby increasing the sealing between the expansion plate 403 and the adjustment piece 2, avoiding leakage of the center rod during expansion.

[0024] like Figure 3 As shown, the right end of the connecting rod 8 is connected with a cover 9, which serves as an outer cover for the hydraulic gas rod 11, and a folding hole 10 is provided inside the bottom of the cover 9, and the hydraulic gas rod 11 is installed inside the folding hole 10. The hydraulic gas rod 11 drives the connecting rod 8 to move outward relative to the center of the center rod through telescoping, and the folding hole 10 and the cover 9 are an integrated structure. An auxiliary component 12 for auxiliary adjustment is provided on the side of the cover 9, and the auxiliary component 12 is provided in three groups. The auxiliary component 12 includes an auxiliary sleeve 1201 and an anti-drift rod 1202, and the anti-drift rod 1202 is provided inside the auxiliary sleeve 1201. When the auxiliary sleeve 1201 moves outside the anti-drift rod 1202, it assists the movement and adjustment of the cover 9, thereby increasing the stability of the movement of the connecting rod 8.

[0025] In summary, the ultrasonic knife center rod with an expansion structure is firstly based on Figure 1-Figure 3In the structure shown in , when the center rod is expanded, the two groups of hydraulic gas rods 11 are controlled to extend at the same time. When the hydraulic gas rods 11 extend, the cover 9 is driven to move. When the cover 9 moves, the connecting rod 8 and the connecting block 7 drive the two groups of adjusting plates 2 to move outward away from the center point of the center rod. When moving outward, the limiting groove 401 allows the adjusting block 402 to limit and adjust the movement to avoid the expansion plate 403 from moving offset during expansion. When expanding outward, the adjusting plate 2 moves inside the expansion plate 403, thereby expanding the center rod and increasing the large diameter of the center rod. When expanding outward, the sealing plate 404 itself avoids leakage of the center rod during expansion by telescoping.
