Description

Technical Field

[0001] The invention relates to the field of medical devices, in particular to a disposable appendectomy ligation device. Background Art

[0002] The appendix, also known as the lumbrical process, is a long, thin, curved blind tube located in the lower right side of the abdomen, between the cecum and ileum. Its root is connected to the posteromedial wall of the cecum, while its distal end is free and closed. Its range of motion varies greatly from person to person, influenced by factors such as the mesentery, allowing the appendix to extend into any position in the abdominal cavity. The appendix is ​​located in the lower right side of the abdomen, between the cecum and ileum. It is a long, thin, curved blind tube with a closed distal end.

[0003] Appendicitis is an inflammatory condition caused by a variety of factors. It is a common surgical disease, most common in young adults and more common in men than women. Clinically, acute appendicitis is relatively common and can occur in women of all ages, including those during pregnancy.

[0004] Common treatments for appendicitis include appendectomy, which is used to treat acute appendicitis, suppurative appendicitis, and gangrenous appendicitis. While generally easy to perform, the procedure can be challenging, such as in the case of an ectopic appendix. Therefore, appendectomy should never be considered a minor procedure. It must be taken seriously to improve treatment outcomes and avoid or minimize postoperative complications and sequelae.

[0005] With the development of minimally invasive surgical techniques, the degree of damage to the human body caused by appendectomy has gradually decreased. Endoscopic surgery is usually used, using an appendectomy band, and the appendectomy can be completed without laparotomy. However, in endoscopic appendectomy, the loop of the traditional appendectomy band is in a free state during the process of entering the human body, which increases the resistance to entry. At the same time, a larger diameter pneumoperitoneum channel is established, which also increases the risk of interference with other instruments. The operation is more difficult and requires a lot of experience from the surgeon, resulting in high surgical costs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a disposable appendectomy ligation device that is easy to use. The loop is hidden in the cavity during the process of entering the human body, reducing entry resistance and the risk of interference with other instruments or human tissues; after reaching the lesion location, the outer sleeve is rotated and the loop automatically pops out, and the operation can be performed, effectively reducing the operation time and effectively reducing the difficulty of minor operations.

[0010] The sliding flange matches the size of the ring slide groove;

[0011] The arc-shaped tube body and the tie groove can form a closed cavity.

[0012] As a further improvement of the present invention, the sliding flange is an inner flange.

[0013] As a further improvement of the present invention, the hidden tie groove and the tie groove are located on the same side of the sleeve body.

[0014] As a further improvement of the present invention, the upper section and the lower section of the cable tie through hole are coaxial, and the middle portion of the cable tie through hole is an arc-shaped hole; the arc-shaped hole matches the shape of the cable tie groove.

[0034] like Figures 1 to 9 The disposable appendectomy ligation device shown in the figure comprises an outer sleeve 3, a ligation band 1, and an inner sleeve 2. The ligation band 1 can be of conventional design. Because the loop 4 at its lower end is made of elastic material and can only be tightened in one direction, it is an excellent ligation material for appendectomy surgery. Furthermore, due to its excellent elasticity, it can automatically eject from the cavity when the cavity is opened.

[0035] The inner sleeve 2 is coaxially installed in the outer sleeve 3 and can rotate with each other; the ligature 1 is installed in the inner sleeve 2 and can move axially relative to the inner sleeve 2; since the sliding flange 3-5 is engaged in the annular groove 2-5, the inner sleeve 2 and the outer sleeve 3 can move axially at the same time, which is convenient for operation.

[0036] The inner sleeve 2 includes a sleeve body 2-2, a tie groove 2-4 on the outside of the sleeve body 2-2 and a tie through hole 2-3 inside the sleeve body 2-2; the lower end of the sleeve body 2-2 is a cone, and a hidden tie groove 2-7 is opened on one side of the cone; the sleeve body 2-2 is also provided with a ring slide groove 2-5, and a stopper 2-6 is installed at the end of the ring slide groove 2-5; at least one stopper 2-6 is provided to prevent the sliding flange 3-5 from accidentally falling out of the ring slide groove 2-5.

[0037] The hidden belt groove 2-7 is used to hold the belt body of the ligature belt 1 to prevent the belt body from being exposed outside the cone, thereby reducing friction and unnecessary contact with the pneumoperitoneum channel during entry into the human body. The hidden belt groove 2-7 is parallel to the cone direction of the lower end of the sleeve body 2-2.

[0038] The outer sleeve 3 includes a circular tube 3-3 and an arcuate tube 3-4. The arcuate tube 3-4 is connected to the lower end of the circular tube 3-3. A sliding flange 3-5 is provided at the lower end of the arcuate tube 3-4. The circular tube 3-3 and the arcuate tube 3-4 are hollow structures, each forming a hollow hole. The curvature of the arcuate tube 3-4 is greater than the curvature of the tie groove 2-4.

[0039] The sliding flange 3-5 matches the size of the ring slide groove 2-5; the sliding flange 3-5 slides back and forth in the ring slide groove 2-5.

[0040] The arc-shaped tubular body 3-4 and the tie-band groove 2-4 can form a closed cavity. This cavity is used to store the ring sleeve 4, and the corresponding belt body of the tie-band 1 just fits into the hidden belt groove 2-7 at this moment.

[0041] Furthermore, the sliding flange 3-5 is an inner flange.

[0042] Furthermore, the hidden tie groove 2-7 and the tie groove 1 are located on the same side of the sleeve body 3-3.

[0043] Furthermore, the upper section and the lower section of the cable tie through hole 2-3 are coaxial, and the middle portion of the cable tie through hole 2-3 is an arc-shaped hole; the arc-shaped hole matches the shape of the cable tie groove 2-4.

[0044] Furthermore, the outer side of the lower end of the arc-shaped tube body 3-4 is tapered, and its outer edge matches the outer edge of the cone.

[0045] Furthermore, a lifting block 2 - 1 is symmetrically provided on the upper end of the sleeve body 2 - 2 for tightening the ring sleeve 4 .

[0046] Furthermore, a rotating block 3-2 is provided at the upper end of the circular tube 3-3 for rotating the circular tube 3-3, that is, realizing the rotation between the circular tube 3-3 and the inner sleeve 2.

[0047] Furthermore, a ring 4 is provided at the lower end of the tying belt 1 .

[0048] Furthermore, the cable tie grooves 2 - 4 are concave arc-shaped grooves.

[0049] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solutions formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
