Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a soft palate fixation and protection device. Background Technology

[0002] During adenoidectomy, the soft palate can obstruct the procedure because the adenoids are located at the top of the nasopharynx. To ensure adequate exposure of the surgical area and facilitate the surgeon's work, a soft palate fixation device is used to pull and fix the soft palate forward and upward.

[0003] Currently, traditional soft palate fixation devices generally consist of a urinary catheter, sutures, and metal hooks. The method of using a urinary catheter to fix the soft palate involves inserting it through one nostril, passing through the nasopharynx, and exiting through the oral cavity. During the procedure, the catheter needs to be adjusted to pull the soft palate upwards, which significantly increases preoperative preparation time. Furthermore, the pressure from the catheter is concentrated at the nasal vestibule or soft palate contact point during traction, potentially causing mucosal ischemia, edema, or even pressure necrosis. Uneven traction can also lead to localized pressure or slippage of the soft palate. Additionally, the catheter can only pull the soft palate in one direction, limiting exposure to the posterior nasopharynx, especially in cases of adenoid hypertrophy or nasopharyngeal stenosis. This can result in insufficient exposure of the surgical field, increasing the risk of adenoid remnant. Therefore, there is an urgent need to research a soft palate fixation and protection device to address these problems. Utility Model Content

[0004] The present invention provides a soft palate fixation and protection device, the purpose of which is to solve the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a soft palate fixing and protection device, including a net bag for wrapping around the soft palate and a first strap and a second strap connected to the edge of the net bag; the first strap and the second strap are disposed on opposite sides of the net bag; when the first strap and the second strap are both straightened, the length direction of the first strap is parallel to the length direction of the second strap; the end of the first strap away from the net bag can be connected to the end of the second strap away from the net bag.

[0007] As a preferred embodiment of this utility model, the edge of the net bag has a flange; the end of the first strip near the net bag and the end of the second strip near the net bag are both connected to the flange.

[0008] As a preferred embodiment of this utility model, both the first strip and the second strip are silicone soft strips.

[0009] As a preferred embodiment of this utility model, the first strip has multiple through holes arranged side by side at the end away from the net, and the arrangement direction of the multiple through holes is consistent with the length of the first strip; the second strip has multiple protruding posts fixed side by side at the end away from the net; the multiple protruding posts can be respectively inserted into the multiple through holes.

[0010] As a preferred embodiment of this utility model, the length direction of the plurality of protrusions is perpendicular to the length direction of the second strip, and any one of the protrusions is either interference-fitted or clearance-fitted with the corresponding through hole.

[0011] As a preferred embodiment of this utility model, the circumferential sidewalls of the plurality of protruding posts are provided with barbs; when the protruding post is inserted into the through hole, the through hole is located between the barbs on the protruding post and the second strip.

[0012] This utility model has the following beneficial effects:

[0013] This invention involves inserting a first band into the patient's nostril, passing through the nasopharynx, and exiting through the oral cavity. The net between the first and second bands easily covers the soft palate. After connecting the end of the first band away from the net to the end of the second band away from the net, pulling the first and second bands outwards pulls the net upwards, fully exposing the surgical field. This not only achieves comprehensive coverage of the soft palate but also provides even traction, effectively avoiding problems such as local pressure or slippage of the soft palate. It also reduces the probability of residual adenoids and shortens the preoperative preparation time.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 As shown, this utility model is a soft palate fixing and protection device, including a net bag 1 for wrapping around the soft palate and a first strap 2 and a second strap 3 connected to the edge of the net bag 1; the first strap 2 and the second strap 3 are disposed on opposite sides of the net bag 1; when both the first strap 2 and the second strap 3 are straightened, the length direction of the first strap 2 is parallel to the length direction of the second strap 3; the end of the first strap 2 away from the net bag 1 can be connected to the end of the second strap 3 away from the net bag 1. Figure 5-6As shown, during use, the first band 2 is inserted into the patient's nostril, passes through the nasopharynx, and exits through the oral cavity. The net 1, located between the first band 2 and the second band 3, easily wraps around the soft palate. After connecting the end of the first band 2 away from the net 1 to the end of the second band 3 away from the net 1, pulling the first band 2 and the second band 3 outwards pulls the soft palate upwards, fully exposing the surgical field and facilitating the surgeon's operation. This not only provides comprehensive coverage of the soft palate but also ensures even traction, preventing displacement and effectively avoiding problems such as localized pressure or slippage of the soft palate. It also reduces the probability of residual adenoids and shortens preoperative preparation time. Furthermore, the holes in the net 1 provide ventilation, preventing continuous full-contact pressure on the soft palate tissue and avoiding postoperative tissue edema caused by continuous pressure. During surgery, the net 1 also protects the soft palate, preventing accidental contact and damage from electrocautery or plasma scalpels.

[0027] Among them, such as Figure 2 As shown, the net 1 has a thin-walled structure, and the edge of the net 1 is integrally formed with a flange 101. The first strip 2 and the second strip 3 near the net 1 are both connected to the flange 101. The net 1 and the flange 101 are both made of soft silicone material, and the first strip 2 and the second strip 3 are both soft silicone strips. That is, the net 1, the flange 101, the first strip 2, and the second strip 3 are integrally formed. By making the net 1, the flange 101, the first strip 2, and the second strip 3 all made of soft silicone material, it is not only convenient for the soft palate fixation and protection device to enter the nasal cavity, but also ensures the wrapping effect of the net 1 on the soft palate. While the net 1 wraps the soft palate, the flange 4 adheres to the soft palate, which can effectively disperse pressure, reduce the risk of local damage, and further improve the protection effect on the soft palate.

[0028] Example 2:

[0029] Based on Example 1, as follows Figure 1-2 and Figure 4As shown, the first strip 2 has multiple through holes 201 arranged side by side at one end away from the net bag 1, and the arrangement direction of the multiple through holes 201 is consistent with the length of the first strip 2; the second strip 3 has multiple protrusions 301 fixed side by side at one end away from the net bag 1; the multiple protrusions 301 can be inserted into the multiple through holes 201 respectively; the length direction of the multiple protrusions 301 is perpendicular to the length direction of the second strip 3, and at any time, there is an interference fit or clearance fit between the protrusion 301 and the corresponding through hole 201. In this utility model, a clearance fit is adopted; the circumferential sidewalls of the multiple protrusions 301 are integrally formed with barbs 302; the barbs 302 are made of hard plastic; when the protrusion 301 is inserted into the through hole 201, the through hole 201 is located between the barb 302 on the protrusion 301 and the second strip 3. In use, the first band 2 is inserted into the patient's nostril, passes through the nasopharynx, and exits through the oral cavity. The net 1, located between the first band 2 and the second band 3, easily covers the soft palate. The appropriate position of the through hole 201 can be selected according to the size required by the patient, and the protrusion 301 is matched with the through hole 201. The through hole 201 is located between the barb 302 on the protrusion 301 and the second band 3. Then, the net 1 pulls the soft palate upward to expose the adenoids, which facilitates the adenoid removal surgery. After the surgery is completed, the barb 302 cannot be removed from the through hole 201. At this time, the first band 2 or the second band 3 can only be cut to remove the soft palate fixation and protection device. This ensures that the soft palate fixation and protection device can only be used once.
