Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to a packing material for lacrimal cystorhinostomy or nasal surgery. Background Art

[0002] At present, after the lacrimal sac is incised during endoscopic dacryocystorhinostomy (En-DCR) surgery, in order to keep the lacrimal sac incision open for a long time, it is necessary to promote the adhesion and healing between the nasal mucosa and the lacrimal sac mucosa. Since there is no special stoma packing dressing at present, the stoma is usually supported and packed with degradable expansion sponges, hemostatic sponges or non-degradable expansion sponges commonly used in nasal surgery, and the wound is hemostatically controlled with gelatin sponges or hemostatic patches, hemostatic powders and other dressings with hemostatic functions. The existing hemostatic sponges or expansion sponges are generally strip-shaped or sheet-shaped with a certain thickness. When used, they need to be manually trimmed into a shape and size suitable for the stoma, and they are filled into the stoma site with medical equipment, which takes a long time and increases the difficulty of operation. The stoma filling cannot be completed in time and quickly, and the manually trimmed hemostatic sponges or expansion sponges are very likely to produce size errors, affecting the hemostasis or support effect, and thus affecting the surgical treatment effect; in addition, although there are some stoma stents made of materials such as silicone, they have not been widely promoted and applied due to their high prices.

[0003] Therefore, it is necessary to design a packing material which is low in manufacturing cost and convenient and quick to use and is suitable for dacryocystorhinostomy or nasal surgery. Summary of the invention

[0004] In order to solve the above technical problems, the utility model proposes a packing for lacrimal cystorhinostomy or nasal surgery, which can be suitable for use as a packing in lacrimal cystorhinostomy and other nasal surgeries, can be directly applied to the stoma position without artificial trimming, is quick and easy to place and remove, can effectively shorten the operation time, and improve the operation efficiency. At the same time, it can enhance the hemostasis and support effects after swelling in water, ensure that the artificial incision is in an open state, and thus guarantee the surgical treatment effect.

[0040] Embodiment 1:

[0041] like Figure 1~Figure 2 As shown, the utility model provides a packing for lacrimal cystorhinostomy or nasal surgery, which includes a packing block 1 that can expand when in contact with water. The packing block 1 is a conical block that is narrow at the top and wide at the bottom, and its cross-section is circular, that is, the packing block 1 is conical, which can facilitate the pushing, placement and removal of the packing.

[0042] The packing block 1 is provided with a longitudinally penetrating accommodating through hole 2, and the aperture size of the accommodating through hole 2 can be set according to the specific usage scenario and needs. If medical instruments such as clamps or tweezers are used for clamping and placement, the accommodating through hole 2 can be arranged to be adapted to the tip of the clamp or tweezers to facilitate clamping by the clamp or tweezers. If used in conjunction with a lacrimal duct probe and a lacrimal duct catheter, the accommodating through hole 2 is larger than the diameter of the traction guide wire of the lacrimal duct probe and the lacrimal duct catheter, so that the traction guide wire can pass through the accommodating through hole 2 to pull the packing block 1 to fill the stoma.

[0043] The accommodating through hole 2 is arranged at the center of the filling block 1 . The accommodating through hole 2 is a straight tube through hole, which coincides with the center axis of the conical filling block 1 .

[0044] Optionally, in some embodiments, the packing block 1 is a degradable packing block 1. After being implanted for a period of time, the packing block 1 can automatically degrade without manual removal. Specifically, a degradable dressing made of materials such as polyetherester-urethane, hydroxyethyl cellulose, plant polysaccharides, chitosan, etc. can be used.

[0045] refer to Figure 1 As shown, the top and bottom edges of the packing block 1 are provided with rounded structures to avoid sharp damage to the lacrimal duct tissue during placement or removal.

[0046] like Figure 2 As shown, the specific application of the packing in this embodiment in nasal surgery can replace the existing hemostatic cotton and hemostatic patch. It is placed at the turbinate inside the nasal cavity. Due to its conical structure, it can play a good hemostatic and supporting role, and after swelling in water, it can improve the stability of its placement and is not easy to fall off.

[0047] Embodiment 2:

[0048] For Example 2 of the utility model, Figure 3 , Figure 4 Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.

[0049] like Figure 3 , Figure 4 As shown, the packing for lacrimal cystorhinostomy or nasal surgery involved in the utility model also includes a traction line 3, wherein the traction line 3 is embedded in the accommodating through hole 2, and both ends thereof extend out of the top and bottom of the packing block 1. Only the length of part of the traction line 3 is shown in the figure, and its specific length can be set as needed.

[0050] The traction line 3 and the packing block 1 are in an integrated structure. The packing block 1 can be pulled through the nasal cavity to the lacrimal cystostomy by pulling the traction line 3. For the specific steps, please refer to the schematic diagram. Figure 4 .

[0051] Optionally, in some embodiments, the traction line 3 is a degradable traction line 3, and the filling block 1 is a degradable filling block 1. After the filling material of this embodiment is implanted, it does not need to be subsequently removed and can be self-dissolved.

[0054] like Figure 5 , Figure 6 As shown, the utility model relates to a packing for lacrimal cystorhinostomy or nasal surgery, wherein the traction line 3 is fixedly arranged in the accommodating through hole 2, and when the packing block 1 swells with water, the traction line 3 can be moved and separated from the accommodating through hole 2; that is, before the packing is implanted, the traction line 3 is fixedly connected to the packing block 1, and the traction line 3 can be pulled to complete the placement and implantation of the packing block 1 into the stoma. As the packing block 1 swells with water, the accommodating through hole 2 is in an expanded state, and at this time, the traction line 3 is separated from the wrapping and fixing of the accommodating through hole 2, and the traction line 3 can be pulled out to leave only the packing block 1 at the stoma, thereby reducing the patient's discomfort.

[0055] Optionally, in some embodiments, the traction line 3 includes an independent upper traction line and a lower traction line (not shown in the figure), wherein one end of the upper traction line is embedded in the accommodating through hole 2, and the other end extends outward from the top of the filling block 1, and one end of the lower traction line is embedded in the accommodating through hole 2, and the other end extends outward from the bottom of the filling block 1.

[0056] The upper traction line is fixedly arranged in the accommodating through hole 2, and when the stuffing block 1 swells when exposed to water, the upper traction line can move and detach from the accommodating through hole 2, thereby pulling out the upper traction line; the lower traction line and the stuffing block 1 are an integrated structure, that is, the lower traction line is firmly fixedly connected to the stuffing block 1, so that the lower traction line is still fixedly connected to the stuffing block 1 after the stuffing block 1 expands, reducing the difficulty of removing the stuffing block 1 later.
