Description

Technical Field

[0001] The invention relates to the technical field of medical suture cutting, in particular to a cutting device for medical suture. Background Art

[0002] Medical sutures are special wires used to suture tissues or organs during surgery. They are divided into absorbable and non-absorbable types based on the material. During surgery, surgeons usually require a wire length that suits specific suturing needs to improve the efficiency and accuracy of the operation. Nurses are responsible for cutting sutures to a fixed length to ensure that doctors can use them quickly without having to be distracted by operating the sutures during surgery, saving time and reducing the risk of contamination. This kind of teamwork is an important part of ensuring the smooth progress of the operation.

[0003] In the prior art, nurses usually use scissors to cut fixed-length medical sutures at the surgical site. After the fixed-length medical sutures are cut, both ends are in a loose state, resulting in the fibers of the thread ends being scattered and irregular. This not only increases the difficulty of inserting the sutures into the suture needle holes, but also easily causes the fibers to fall off, affecting the efficiency and cleanliness of the operation. Especially in emergency medical operations, the time-consuming and labor-intensive problem may affect the progress of the operation and bring inconvenience to medical personnel.

[0045] The pipe diameter of the vacuum bucket 14 is smaller than the diameter of the medical suture. It should be added that the distance between one end of the guide cylinder 34 and one end of the fixed cylinder 36 needs to be set appropriately. When the heating needle 361 moves up to the same height as the two wrapped half cylinders 23, the heating needle 361 will contact one end of the medical suture.

[0046] The specific implementation steps and principles of the present invention are as follows:

[0047] In the initial state, the two wrapped half-cylinders 23 are at the farthest distance apart, the two pulling half-cylinders 241 are at the farthest distance apart, the guide cylinder 34 and the two wrapped half-cylinders 23 are on the same horizontal line, and one end of the medical suture roll set on the fixed baffle 6 extends out from the guide cylinder 34. The nurse pulls out the indicating folding rod 5 from the bottom plate 8 to an appropriate distance according to the cutting length and the scale, and pulls out the extension folding rod 16 from the top of the top plate 9 until one end of the top of the extension folding rod 16 overlaps one end of the indicating folding rod 5. The vertical handle 10 is pulled upward by manpower, and the entire rectangular column 12 is moved horizontally until the rectangular column 12 contacts the microswitch 91. At this time, the vacuum bucket 14 uses negative pressure to draw the suture inside the guide cylinder 34 to the bottom of the arc pressure plate 13, and the vertical handle 10 is pressed down by manpower, and one end of the medical suture is clamped by the arc pressure plate 13, and finally the rectangular column 12 is moved horizontally to the extreme position of the guide groove 161.

[0048] After the micro-cylinder 39 drives the cutting blade 40 to complete the cutting work, the central motor 19 starts, drives the middle cross bar 20 to move upward, pushes the two wrapped half-cylinders 23 to merge through the middle oblique rod 21, and drives the two pulling half-cylinders 241 to merge through the synchronous cross bar 201, and drives the guide cylinder 34 to move upward through the driving cross bar 18. At this time, the heating needle 361 moves to the same horizontal height as the two pulling half-cylinders 241, and starts the common cylinder 33. The common cylinder 33 drives the switching U-seat 331 and drives the U-seat 31 to move horizontally. During this process, the switching U-seat 331 drives the heating needle 361 to extend into one end of the two wrapped half-cylinders 23 through the driving block 37, and the driving U-seat 31 drives the edge cross bar 25 to move horizontally. The two pulling half-cylinders 241 pull one end of the medical suture thread to the inside of the two wrapped half-cylinders 23 by pulling one end of the medical suture thread, and finally starts the heating needle 361 to complete the hot melt sealing of one end of the medical suture thread.
