Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular, to an intradermal suture fixation device. Background Art

[0002] Nowadays, the requirements for aesthetics of surgical incision suture are getting higher and higher. When surgical incisions are layered and sutured to the skin layer, a variety of suture methods can be selected. The most common ones are skin interrupted suture, intracutaneous interrupted suture, and intracutaneous continuous suture. Intracutaneous continuous suture is divided into absorbable suture and non-absorbable suture. If absorbable suture is used, the knots at the head and tail are generally left in the skin or subcutaneous. The absorption time of the suture varies depending on the selected suture. When non-absorbable suture is used for intracutaneous continuous suture, the selected suture has a smooth surface, the head and tail are left outside the skin, and simply knotted or fixed with different materials to prevent the suture from slipping into the skin. The fixing materials at both ends of the intracutaneous continuous suture are mostly medical plastic pipes, which are cut and applied. The tightness of the suture is unstable, which varies according to the suture level of the surgeon, and there is a possibility of slippage. Therefore, a suture fixing device is needed to quickly clamp the suture head and tail to fix the suture firmly. Utility Model Content

[0047] The first clamp shell 11 and the second clamp shell 16 are both made of medical rubber, and are provided with rounded corners. A lower groove 12 is provided on the top wall of the first clamp shell 11, and a plurality of first rubber blocks 15 are provided and fixedly connected to the groove wall of the lower groove 12 at equal intervals. An upper groove 17 is provided on the bottom wall of the second clamp shell 16, and a plurality of second rubber blocks 18 are provided and fixedly connected to the groove wall of the upper groove 17 at equal intervals. The first clamp shell 11 and the second clamp shell 16 are clamped together by a clamping piece, and the first clamp shell 11 and the second clamp shell 16 are clamped together so that the lower groove 12 and the upper groove 17 are spliced ​​to form a square groove 25. The height of the first rubber block 15 is greater than the groove height of the square groove 25, and the height of the second rubber block 18 is greater than the groove depth of the square groove 25. The first rubber block 15 and the second rubber block 18 are respectively staggered along the horizontal extension direction of the square groove 25.

[0048] The top wall of the first clamping shell 11 is provided with symmetrical threaded holes 14, and the end wall of the second clamping shell 16 is provided with symmetrical circular holes 21, and when the first clamping shell 11 and the second clamping shell 16 are clamped, the threaded holes 14 and the circular holes 21 correspond to each other in vertical position, and the circular holes 21 are connected with the threaded holes 14. A limiting groove 26 is provided in the second clamping shell 16 below the circular hole 21, and a bolt 20 is inserted into the circular hole 21, and the bolt 20 extends downward and a part of the bolt 20 is located in the limiting groove 26. A limiting ring 27 is fixedly connected to a part of the bolt 20 located in the limiting groove 26, and the lower end of the bolt 20 is inserted into the threaded hole 14 and is threadedly connected with the threaded hole 14. The upper end of the bolt 20 is rotatably connected to a rotating shaft 28, and both ends of the rotating shaft 28 are respectively fixedly connected to the inner ring wall of the pull ring 22. The rotating shaft 28 is made of medical rubber. The rotating shaft 28 passes through the upper end of the bolt 20 and there is friction between the rotating shaft 28 and the upper end of the bolt 20. When the pull ring 22 is not affected by external artificial forces, the pull ring 22 is horizontally set in the circular hole 21.

[0049] The clamping member includes: a U-shaped clamping block 19; a plurality of clamping grooves 13 are evenly spaced on the top wall of the first clamping shell 11; the U-shaped clamping block 19 is provided with a plurality of and evenly spaced fixedly connected to the bottom wall of the second clamping shell 16; the U-shaped clamping block 19 is made of medical rubber and has elasticity; inclined side walls 23 are provided on the two side walls of the U-shaped clamping block 19; and a protrusion 24 is fixedly connected to the upper part of the inclined side wall 23. The groove width of the clamping groove 13 is greater than the spacing between the two inclined side walls 23, and the groove width of the clamping groove 13 is less than the spacing between the two protrusions 24. Each U-shaped clamping block 19 corresponds to one of the clamping grooves 13.

[0050] Working or installation process:

[0051] Initial state: the first clamp shell 11 and the second clamp shell 16 are separated and do not contact each other, the pull ring 22 is completely horizontally located in the circular hole 21, the bolt 20 is inserted into the circular hole 21 and the bolt 20 can rotate around its own axial circumference, and the bolt 20 can slide up and down along the axial extension direction of the circular hole 21.

[0052] According to the required tension of the suture, the surgical suture of corresponding length is placed in the lower groove 12. At this time, the second clamp shell 16 is picked up and aligned with the first clamp shell 11 and the bottom wall of the second clamp shell 16 is fitted with the top wall of the first clamp shell 11, and the U-shaped block 19 is inserted into the corresponding clamping groove 13, so that the arc convex surface of the protrusion 24 is pressed and contacted with the groove wall of the clamping groove 13. At this time, the lower end of the bolt 20 is inserted into the threaded hole 14 and the bolt 20 is rotated forward so that the lower end of the bolt 20 is threadedly connected with the threaded hole 14. The first clamp shell 11 and the second clamp shell 16 are fixed by the clamping connection between the U-shaped block 19 and the clamping groove 13 and the threaded connection between the bolt 20 and the threaded hole 14. At this time, the suture is located in the square groove 25 formed by splicing the lower groove 12 and the upper groove 17. Since the height of the first rubber block 15 is greater than the groove height of the square groove 25 and the first rubber block 15 is made of medical rubber, the height of the second rubber block 18 is greater than the groove height of the square groove 25 The groove is high and the second rubber block 18 is made of medical rubber. The first rubber block 15 and the second rubber block 18 are elastic and can be deformed. The top wall of the first rubber block 15 is pressed against the top wall of the upper groove 17 and deformed (that is, the first rubber block 15 and the groove wall of the upper groove 17 have an interference fit), and the bottom wall of the second rubber block 18 is pressed against the bottom wall of the lower groove 12 and deformed (that is, the second rubber block 18 and the groove wall of the lower groove 12 have an interference fit). A part of the suture is pressed between the first rubber block 15 and the upper groove 17. The first rubber block 15 and the second rubber block 18 are staggered. The suture located in the square groove 25 is concave and convex and distributed along the horizontal extension direction of the square groove 25. The first rubber block 15 and the second rubber block 18 are respectively interference fit, so that there is friction between the suture and the first rubber block 15 and the second rubber block 18, and a part of the suture located in the square groove 25 cannot be easily detached from the square groove 25.

[0053] When it is necessary to remove the stitches or adjust the tension of the suture, the first clamp shell 11 and the second clamp shell 16 need to be separated. At this time, the medical staff pulls up the pull ring 22 in the circular hole 21 to make the pull ring 22 rotate around the rotating shaft 28, and makes a part of the pull ring 22 rotate to the top of the circular hole 21. The medical staff holds the pull ring 22 and rotates the bolt 20 in the opposite direction, so that the lower end of the bolt 20 is disengaged from the threaded connection with the threaded hole 14. At this time, the pull rings 22 on both sides are pulled at the same time, so that the pull ring 22 drives the bolt 20 to move upward, and the bolt 20 drives the limiting ring 27 to move upward. The limiting ring 27 presses the top wall of the limiting groove 26 and drives the second clamp shell 16 to move upward. The second clamp shell 16 drives the U-shaped block 19 to move upward, and makes the U-shaped block 19 disengage from the threaded hole 14, so that the second clamp shell 16 is completely separated from the first clamp shell 11, and the suture is taken out from the lower groove 12 or the length of the suture in the square groove 25 is adjusted, so as to complete the removal of the suture or adjust the tension.

[0054] The first clamping shell 11 and the second clamping shell 16 are spliced ​​together to form a flat disc structure, which is convenient for wrapping the sutured part with gauze later.
