Description

Technical Field

[0001] The utility model belongs to the technical field of surgical and medical auxiliary tool structures, and in particular relates to an surgical field exposure device for plasma radiofrequency ablation of adenoids, tonsils, etc. Background Art

[0002] Adenoids and tonsils are common diseases, more common in children. Currently, for children with poor results after conservative treatment, the common method is to perform low-temperature plasma radiofrequency ablation of the tonsils and adenoids. The adenoids are located in the hidden nasopharynx. Under normal circumstances, the nasopharynx is small, and due to tonsil hypertrophy and adenoid hypertrophy, the nasopharynx is even smaller. The common surgical method is to enter and expose the tonsil and adenoid structures through the natural channel of the mouth, and perform separate ablations under an angled endoscope or indirect nasopharyngoscope. Among them, the commonly used nasopharyngeal surgical field exposure tools are mostly disposable gastric tubes / urinary catheters. The gastric tubes / urinary catheters are passed through the anterior nostrils and then removed from the mouth. The two ends of the disposable gastric tubes / urinary catheters are then clamped to lift the soft palate, maximally exposing the nasopharyngeal surgical cavity and ensuring that the adenoids are ablated under a good field of vision.

[0003] However, traditional gastric tubes / urinary catheters are made of thin strips of material. Even when the two ends are tightened to lift the soft palate to the maximum, the exposed surgical field is still unsatisfactory due to the limited contact area between the gastric tube / urinary catheter and the soft palate. Unclear and incomplete exposure of the surgical field can easily affect the effect of the operation, increasing the risk of collateral damage on the one hand, and on the other hand, due to uneven linear local compression force, it can easily lead to severe edema of the soft palate and uvula mucosal tissue after surgery, aggravating the child's postoperative discomfort and respiratory obstruction. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide a surgical field exposure device for plasma radiofrequency ablation of adenoids and tonsils, which can lift the entire soft palate over a large area when in use and make the soft palate evenly stressed, so as to better expose the nasopharyngeal surgical cavity and ensure that the adenoid ablation surgery is completed under a good field of view.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A surgical field exposure device for plasma radiofrequency ablation of adenoids and tonsils comprises a soft belt and a fan-shaped piece arranged at one end of the soft belt. The fan-shaped piece is provided with a connecting portion, and the other end of the soft belt is detachably connected to the connecting portion. The fan-shaped piece is folded to form a column, and the surface of the column is wrapped with a fixing film.

[0007] Furthermore, the tip of the sector-shaped piece is integrally connected to the end of the soft belt, and both the soft belt and the sector-shaped piece are made of silicone rubber material.

[0008] Furthermore, the connecting portion is located on an extension line of the length direction of the soft belt, and the connecting portion is a through hole opened on the fan-shaped piece, and the end of the soft belt is passed through the through hole.

[0009] Furthermore, the connecting portion is located on an extension line of the length direction of the soft belt, and the connecting portion includes a fixing ring provided on the fan-shaped piece, and the fixing ring is provided for the end of the soft belt to pass through.

[0010] Furthermore, both ends of the sector piece along the circumferential direction are symmetrically arranged with respect to the soft belt.

[0011] Furthermore, the sector angle of the sector piece is 45° to 60°.

[0012] Furthermore, the length of the soft belt is 18±3 cm, and the radius of the sector-shaped piece is 12±3 cm.

[0013] Furthermore, the outer diameter of the soft belt is 5±1 mm; the outer diameter of the column with the fixed membrane is 6±1 mm.

[0014] The utility model has the following beneficial effects:

[0015] The utility model is provided with a connected soft belt and a fan-shaped piece, and the fan-shaped piece is folded to form a cylinder, and a fixed membrane is wrapped on the surface of the cylinder. Therefore, before the low-temperature plasma radiofrequency ablation of adenoids and tonsils, the cylinder with the fixed membrane can be inserted into the nasal cavity and then taken out from the oral cavity. After the fixed membrane is removed, the cylinder is unfolded to form a fan-shaped piece. The fan-shaped piece can cover the entire soft palate. When the end of the soft belt is connected to the connecting part and the end of the soft belt is lifted, the fan-shaped piece can contact and lift the soft palate combined with the uvula with the maximum area, and make the soft palate as a whole evenly stressed, so as to prevent the soft palate tissue or the uvula from being locally stressed and edematous, and can better expose the surgical field. At the same time, due to the large-area shielding of the fan-shaped piece, the secondary damage caused by accidental contact of the plasma knife can be reduced, thereby improving the safety of operation.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Terms such as "upper," "inner," "middle," "left," "right," and "one" used in this specification are for ease of description and are not intended to limit the scope of the present invention. Changes or adjustments to these terms, without substantially altering the technical content, are also considered within the scope of the present invention.

[0023] The utility model provides a surgical field exposure device for low-temperature plasma radiofrequency ablation of adenoids and tonsils. When the surgical field exposure device is used, the soft palate tissue and uvula can be wrapped over a larger range to increase the contact area with the soft palate. When the soft palate is lifted, the surgical field can be better exposed to facilitate low-temperature plasma radiofrequency ablation, and reduce accidental injuries caused by accidental contact of the low-temperature plasma blade during the operation, while reducing the risk of postoperative edema caused by local force and pressure on the soft palate and uvula mucosa.

[0024] The structure and function of the surgical field exposure device of the present invention are introduced as follows:

[0025] A surgical field exposure device for plasma radiofrequency ablation of adenoids and tonsils, such as Figures 1 to 5 As shown, it includes a soft belt 1 and a fan-shaped piece 2 arranged at one end of the soft belt 1. The fan-shaped piece 2 is provided with a connecting portion, and the other end of the soft belt 1 is detachably connected to the connecting portion. The fan-shaped piece 2 is folded to form a column 20, and the surface of the column 20 is wrapped with a fixed membrane 3. Therefore, before performing low-temperature plasma radiofrequency ablation of adenoids and tonsils, the column 20 with the fixed membrane 3 can be inserted into the nasal cavity and then taken out of the mouth. After that, the fixed membrane 3 is torn off to allow the column 20 to unfold to form the fan-shaped piece 2. Then, the end of the soft belt 1 is connected to the connecting portion, and the soft belt 1 is lifted by hand, and the soft palate is lifted at the same time to expose the surgical field. During this process, the fan-shaped piece 2 can contact the soft palate tissue and uvula over a larger area, so that the force is evenly distributed during the lifting process and the possibility of accidental injury by the low-temperature plasma knife is reduced.

[0026] In this embodiment, the length of the soft belt 1 is 18 ± 3 cm, and the radius of the sector-shaped piece 2 is 12 ± 3 cm. The surgical field exposure device of the present invention can be designed to have different specifications by adjusting the length of the soft belt 1 and the radius of the sector-shaped piece 2 according to different ages; therefore, in subsequent actual use, the corresponding specifications can be selected according to the age of the child to improve operational efficiency.

[0027] In this embodiment, the tip of the sector-shaped piece 2 is integrally connected to the end of the soft belt 1, and the soft belt 1 and the sector-shaped piece 2 are both made of silicone rubber material; therefore, the surgical field exposure device of the present invention has better elasticity as a whole. When in use, when the column 20 with the fixed cap and part of the soft belt 1 enter the nasal cavity and oral cavity, the discomfort during the process can be reduced while improving operational safety.

[0028] Among them, the outer diameter of the soft belt 1 is 5±1 mm; the outer diameter of the column 20 with the fixed membrane 3 is 6±1 mm. It can be seen that the outer diameter of the soft belt 1 and the outer diameter of the column 20 with the fixed cap of the surgical field exposure device of the present invention meet the size of the nasal cavity of ordinary people, and therefore meet normal use requirements.

[0029] In this embodiment, the connecting portion is located on the extension line of the length direction of the soft belt 1. Therefore, when the soft belt 1 is connected to the connecting portion and the end of the soft belt 1 is pulled, the pulling force can be concentrated on the soft belt 1, and the deviation of the fan-shaped piece 2 during the pulling process can be reduced, thereby improving the operational convenience and safety.

[0030] At the same time, the two ends of the fan-shaped piece 2 along the circumferential direction are symmetrically arranged about the soft belt 1, which has the advantage of facilitating industrial production, and the fan-shaped angle of the fan-shaped piece 2 is 45° to 60°, which can make the fan-shaped piece 2 better cover the soft palate, so that the soft palate is evenly stressed and the comfort of the lifting process is improved.

[0031] The connection part can be designed into a variety of structures, as follows:

[0032] 1) The connecting portion is a through hole 21 (such as Figure 4 As shown), the through hole 21 is provided for the end of the soft belt 1 to pass through.

[0033] 2) The connecting portion includes a fixing ring (not shown) provided on the sector piece 2, through which the end of the soft belt 1 is passed. Therefore, in actual use, the sector piece 2 can lift the soft palate by pulling the end of the soft belt 1.

[0034] In summary, the utility model is provided with a connected soft belt 1 and a fan-shaped piece 2, and the fan-shaped piece 2 is folded to form a cylinder 20, and a fixed membrane 3 is wrapped on the surface of the cylinder 20; therefore, before low-temperature plasma radiofrequency ablation of adenoids and tonsils, the cylinder 20 with the fixed membrane 3 can be inserted into the nasal cavity and then taken out from the oral cavity. After the fixed membrane 3 is removed, the cylinder 20 can be unfolded to form a fan-shaped piece 2. The fan-shaped piece 2 can cover the entire soft palate. When the end of the soft belt 1 is connected to the connecting part and the end of the soft belt 1 is lifted, the fan-shaped piece 2 can contact and lift the soft palate combined with the uvula with the maximum area, and make the overall force of the soft palate uniform, and can better expose the surgical field. At the same time, due to the large area of ​​shielding of the fan-shaped piece 2, the secondary damage caused by accidental contact of the plasma knife can be reduced, thereby improving the safety of operation.

[0035] The implementation methods of the present invention are not limited to this. According to the above content of the present invention, by utilizing common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, the present invention can also make other various forms of modification, replacement or combination, all of which fall within the scope of protection of the present invention.
