Description

Technical Field

[0001] The utility model relates to an auxiliary treatment device for jaw cysts, in particular to a split-type impression making device for a jaw cyst plugging treatment device. Background Art

[0002] Jaw cyst is a common cystic lesion in the oral and maxillofacial region. It refers to a cystic mass containing fluid in the jaw, mostly in the mandible. Because the disease is asymptomatic in the early stage and grows slowly, it is easy to be ignored. It is often discovered accidentally during X-rays taken during oral disease treatment or when patients come to the hospital for treatment due to symptoms such as jaw bulge, facial deformity and chewing disorder. If it is not treated effectively in time, it can lead to jaw destruction, absorption and even pathological fracture.

[0003] Common treatment methods in clinical practice include fenestration decompression, partial jaw resection, and curettage. Among them, fenestration decompression is becoming increasingly popular in clinical practice, especially for the treatment of large-scale cysts. It is a conservative functional surgical procedure that destroys the integrity of the cyst wall and forms a drainage channel in the oral cavity that communicates with the cyst cavity, so as to achieve the purpose of draining cystic fluid and reducing intracystic pressure, thereby promoting cyst cavity reduction and jaw bone reconstruction. In order to maintain the patency of the drainage channel, it is mainly achieved clinically by wearing a jaw cyst plug.

[0004] At present, for patients who undergo fenestration decompression surgery in clinical practice, when making a jaw cyst plug, the conventional method is mainly used to take a mold using an oral tray. The impression taken is an integrated structure. Due to its long structure, this impression is not easy to be removed from the oral cavity after preparation when the mouth opening is small, the cyst cavity is deep, or it is located in the posterior teeth area. Or it is easy to damage the soft tissue in the oral cavity during the removal process, causing secondary injury, bringing more pain and psychological burden to the patient, and also reducing the confidence of medical staff in taking the impression. In addition, the accuracy is insufficient, resulting in the jaw cyst plug made not fitting, which is not conducive to the cleaning of the patient's cyst drainage port and postoperative recovery.

[0005] Currently, there are improved impression-taking devices. Although the accuracy of impression-taking has been improved, the problem of a long structure still exists. For the above-mentioned patients, after the impression is prepared, it is still not easy to remove it from the mouth, or the soft tissue in the mouth may be easily damaged during the removal process, causing secondary damage, bringing more pain and psychological burden to the patients. In addition, there is still the problem of insufficient accuracy, and therefore, it cannot meet the treatment needs of the above-mentioned patients well. Utility Model Content

[0006] Based on the above problems, the problem to be solved by the utility model is to provide a split-type impression making device which is easy to remove, light, does not damage the soft tissue in the oral cavity, and has high molding accuracy.

[0007] The technical solution of the utility model is as follows:

[0008] A split-type impression making device for a jaw cyst plugging device comprises an upper impression component, a lower impression component and an impression puller; the upper impression component and the lower impression component form two states of adaptive insertion or looseness; the impression puller and the lower impression component form two states of detachable fixed connection or looseness.

[0009] In one embodiment, in the split-type mold making device, the lower end of the upper mold component is provided with an outwardly convex bolt body; correspondingly, the upper end of the lower mold component is provided with an inwardly concave bolt channel; the upper mold component and the lower mold component are formed with two states of adaptive insertion or looseness through the bolt body of the upper mold component and the bolt channel of the lower mold component.

[0010] In one embodiment, in the split-type impression making device, the bolt body of the upper impression component and the bolt channel of the lower impression component are both regular polygonal structures.

[0011] In one embodiment, in the split-type impression making device, the regular polygonal structure is a pentagonal structure.

[0012] In one embodiment, in the split-type mold making device, an internal threaded hole is provided at the center position of the bottom of the bolt channel of the lower mold part, and an external thread is provided at one end of the mold puller; the mold puller and the lower mold part are connected in a detachable or loose state through the external thread of the mold puller and the internal threaded hole of the lower mold part.

[0013] In one embodiment, in the split-type impression making device, the upper impression part and the lower impression part of the impression making device respectively include a column and a wing plate; a lateral vertical design distribution is formed between the wing plate and the column.

[0025] The preferred embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 6 As shown, the utility model provides a split-type impression making device 100 for a jaw cyst plugging device, which includes an upper impression component 300, a lower impression component 200 and an impression pull rod 60. The upper impression component 300 and the lower impression component 200 form a matching plug-in or loose state, and the impression pull rod 60 also forms a detachable active connection with the lower impression component 200, that is, the impression pull rod 60 and the lower impression component 200 form a fixed connection or a loose state. The specific design scheme of the device 100 is as follows.

[0027] In the above-mentioned split-type impression making device 100, in order to facilitate the formation of two states of adaptable insertion or looseness between the upper impression component 300 and the lower impression component 200, a downwardly protruding bolt body 30 is provided at the lower end of the upper impression component 300; correspondingly, an inwardly concave bolt channel 50 is provided at the upper end of the lower impression component 200, and the bolt body 30 of the upper impression component 300 and the bolt channel 50 of the lower impression component 200 are adaptable to be inserted or loosened; the bolt body 30 of the upper impression component 300 and the bolt channel 50 of the lower impression component 200 are adaptable to be inserted, that is, the bolt body 30 of the upper impression component 300 and the bolt channel 50 of the lower impression component 200 form a fixed plug-in connection or a loose state.

[0028] In order to maintain a good insertion, the specifications and dimensions of the plug body 30 and the bolt channel 50 are consistent, and the external shapes and structures are consistent. In this embodiment, the length of the plug body 30 and the depth of the bolt channel 50 are both 3 mm. When preparing the impression, it is necessary to wrap a layer of silicone rubber on the outside of the upper impression part 300 and the lower impression part 200, respectively, and the external shape and structure of the silicone rubber are adapted to the cyst drainage channel, the depth of the cyst cavity, and the soft tissue and dentition around the cyst drainage port. The silicone rubber is used to make a complete impression (composed of the silicone rubber on the outside of the upper impression part 300 and the silicone rubber on the outside of the lower impression part 200). Since the upper impression component 300 and the lower impression component 200 are two separate combined impression components, after the impression is made, the impression is also wrapped around the outside of the entire impression making device 100. When the upper impression component 300 and the lower impression component 200 are respectively taken out of the oral cavity, it is also necessary to ensure that the upper impression component 300 and the lower impression component 200 in the impression making device 100 are separated; at the same time, the impressions shaped by the external silicone rubber of the upper impression component 300 and the lower impression component 200 are also separated; however, the lower impression component 200 and the external silicone rubber must be ensured to be in the cyst drainage channel and the cystic cavity. Therefore, the 3mm size of the bolt body 30 length and the bolt channel 50 depth makes it easy for the upper impression component 300 to be pulled out from the lower impression component 200. After the upper impression component 300 and the lower impression component 200 are used in combination to successfully prepare the impression, it does not hinder the upper impression component 300 and the impression wrapped therein from being taken out of the oral cavity together, and it is also convenient for them to be adapted and inserted outside the oral cavity to form a complete impression, which can play a good role in embracing friction retention.

[0029] Preferably, the bolt body 30 of the upper mold component 300 and the bolt channel 50 of the lower mold component 200 are both regular polygonal structures; for example, the cross-section is a quadrilateral, pentagonal or hexagonal structure. This design can ensure that the upper mold component 300 and the lower mold component 200 form an effective fixed plug-in connection during molding, and after the mold is made, when the upper mold component 300 and the mold wrapped outside are taken out of the oral cavity, the two can be easily loosened.

[0030] In this embodiment, the cross-section of the bolt body 30 and the bolt channel 50 is preferably a pentagonal structure, and the pentagon is a combination of a regular quadrilateral and an isosceles triangle. The pentagon is designed so that the tip of the vertex of the triangle is used for positioning; that is, the combination of a regular quadrilateral and an isosceles triangle is designed so that the tip of the vertex of the isosceles triangle is used for positioning. The upper and lower structures have only one vertex of a triangle, so they can be accurately positioned and combined. That is, the combination direction of the upper and lower structures in the mouth when taking the mold should be consistent with the combination direction of the upper and lower structures after being taken out of the mouth. If they are not consistent, the situation in the mouth cannot be completely reproduced, resulting in the jaw cyst plug not fitting in the mouth.

[0031] Preferably, the lower end of the upper mold component 300 is further provided with an embedded stepped table 42 of cylindrical structure, and the bolt body 30 is arranged on the embedded stepped table 42; correspondingly, the upper end of the lower mold component 200 is provided with an annular embedded stepped hole table 41, and the bolt channel 50 is embedded in the embedded stepped hole table 41. The outer diameter of the embedded stepped table 42 is consistent with the inner diameter of the embedded stepped hole table 41, and the height of the embedded stepped table 42 is consistent with the depth of the embedded stepped hole table 41, both of which are 1 mm. This design is conducive to further ensuring that the upper mold component 300 and the lower mold component 200 form an effective fixed plug-in connection during molding, avoiding the two from loosening, thereby improving the manufacturing accuracy of the mold; at the same time, it is also conducive to further ensuring that an effective embracing friction retention is formed when the upper mold (i.e., the silicone rubber outside the upper mold component 300) and the lower mold (i.e., the silicone rubber outside the lower mold component 200) are combined extraorally.

[0032] The die pull rod 60 is a cylindrical rod, one end of which is provided with an external thread 62, and the other end is provided with an anti-skid structure 61, such as vertical stripes, horizontal stripes, threads or rough surface, etc., to increase friction resistance and prevent slipping during use. The die pull rod 60 is used to facilitate the removal of the lower die component 200 after the die is prepared. Therefore, an internal thread hole 20 is provided at the bottom center of the bolt channel 50 of the lower die component 200, and the external thread 62 of the die pull rod 60 and the internal thread hole 20 of the lower die component 200 form a detachable threaded connection, that is, the die pull rod 60 and the lower die component 200 form two states of threaded connection or looseness. When making the impression, first, the silicone rubber is kneaded and shaped around the outside of the lower impression component 200, and then the lower impression component 200 and the silicone rubber outside are placed in the cyst cavity (not shown in the figure) through the cyst drainage channel (not shown in the figure), and then the upper impression component 300 and the lower impression component 200 are adapted to be plugged and connected to facilitate the production of the overall impression; after the impression is prepared, the upper impression component 300 is loosened from the lower impression component 200 through the tray and the cured machine-adjustable silicone rubber, the impression puller rod 60 is threadedly connected to the lower impression component 200, and the lower impression is pulled out from the patient's cyst cavity.

[0033] In the above-mentioned split-type impression making device, the upper impression part 300 and the lower impression part 200 respectively include a column 40 and a wing plate 10. The column 40 is a cylindrical structure, which is convenient for making an impression, and the wing plate 10 is a square structure, such as a rectangular block or a square block, and is arranged outside the column 40 and perpendicular to the column 40. The main function of the wing plate 10 is to prevent rotation and retention, and can prevent the column 40 from rotating and dislocating during and after the impression is prepared.

[0034] The column 40 and the wing plate 10 can be integrally cast, or can be nested and fixedly connected, or can be integrally formed by machining a whole piece of stainless steel. In this embodiment, the column 40 and the wing plate 10 are cast by a mold-integrated machine.

[0035] Preferably, there are multiple wing plates 10, which are arranged in parallel and symmetrically at intervals in the middle of the outer wall of the column 40. More preferably, each wing plate 10 is designed with inner grooves 11 around it to increase the anti-rotation force and retention force. Four grooves 11 are arranged symmetrically on the side of the wing plate 10 to balance the anti-rotation force and retention force.

[0036] In one embodiment, the upper mold component 300 includes two wing plates 10, which are arranged in parallel and symmetrically, and the four edges of the two wing plates 10 are also distributed in parallel and vertically symmetrically, that is, the vertical projection planes of the two wing plates 10 after being arranged in parallel coincide with each other; the interval between the two wing plates 10 is about 2-4 mm. The lower mold component 200 includes three wing plates 10, and each adjacent two wing plates are arranged in parallel with an interval of 5-7 mm, and the three wing plates 10 are respectively formed in a staggered arrangement around the central axis O in the same clockwise or counterclockwise direction, and the staggered angles of the adjacent two wing plates are the same; that is, the center lines of the three wing plates 10 are line segments a, b, and c, and the line segments a, b, and c form three staggered angles with the central axis O of the column 40 in a unified direction, so that the three wing plates 10 form a spiral ascending or descending structure. Arranged in the same clockwise or counterclockwise direction, the three staggered angles have the same value, all of which are 30°. This structural design is conducive to the hand-adjustable shaping of the silicone rubber, which better enhances the anti-rotation force and retention force.

[0037] The above-mentioned split impression making device can be designed into four models according to different intraoral conditions, such as SI, S-II, LI, and LI I; wherein, the difference between S and L lies in the radius and the size of the anti-rotation wing plate, S represents a small size, and L represents a large size, both of which are proportionally enlarged and reduced; the difference between I and II lies in the length, I represents short, and II represents long, and the four models are suitable for different intraoral conditions; in this way, there are four models of the upper impression component and four models of the lower impression component, because the bolt body 30 and the bolt channel 50 mounted on the lower impression component 200 are the same size regardless of the model, which is equivalent to a total of 16 combinations of the upper impression component and the lower impression component.

[0038] The operation process of the split impression making device is as follows:

[0039] 1. When it is necessary to make an impression, first mix the hand-adjusted silicone rubber according to the ratio of silica gel and hardener, and then shape the hand-adjusted silicone rubber around the outside of the lower impression part 200. The size of the shaping depends on the size of the cyst drainage channel and the depth of the cyst cavity, so as to play a role in blocking the cyst drainage port and supporting it.

[0040] 2. After the impression rod 60 is threadedly connected to the lower impression part 200, the lower impression part 200, which has been manually adjusted and kneaded by silicone rubber, is placed into the cyst cavity through the cyst drainage channel, so that the bottom end of the lower impression is against the bottom of the cyst cavity, and the top end of the lower impression is flush with the gingival end of the cyst drainage channel;

[0041] 3. Insert the upper mold component 300 into the bolt channel 50 of the lower mold component 200 through the bolt body 30;

[0042] 4. Spread the machine-adjustable silicone rubber with good fluidity onto the tray, then buckle the tray together with the machine-adjustable silicone rubber onto the dentition where the lower impression has been placed, press the tray with appropriate force and keep the tray stable, and wait for the machine-adjustable silicone rubber to cure;

[0043] 5. Take out the tray from the oral cavity. At this time, the upper mold component 300 is pulled out of the lower mold component 200 together with the tray after the curing of the machine-adjusted silicone rubber;

[0044] 6. After the impression rod 60 is threadedly connected to the lower impression component 200 again, the lower impression is pulled out of the cyst cavity by the impression rod 60, and the impression rod 60 on the lower impression is removed outside the mouth, and then the lower impression is adapted and snapped into the bolt body 30 of the upper impression through the bolt channel 50, thereby making a complete impression.

[0045] It should be understood that the above description of the preferred embodiments of the utility model is relatively detailed, and it cannot be regarded as a limitation on the scope of patent protection of the utility model. The scope of patent protection of the utility model shall be based on the attached claims.
