[0001] The utility model relates to the technical field of oral implantation, in particular to a special impression tray for oral implantation. Background Art

[0002] The special impression tray for oral implants is a medical device used in oral implant surgery. It is used to make personalized impressions of dental implants or dentures. During oral implant surgery, an impression of the patient's mouth needs to be taken to obtain accurate information about the oral structure and tooth position for the subsequent production of implants or dentures.

[0003] Currently, in the special impression trays for oral implants, if the handle and the tray cannot be disassembled, the entire tray needs to be replaced. Even if only the tray is damaged but the handle is not damaged, it will cause some inconvenience and waste. If the damage to the tray is limited to the tray itself and the handle is intact, but the tray cannot be replaced alone, the tray needs to be replaced as a whole, which will result in the handle and other parts that could have been used being wasted, increasing costs and waste of resources. For this reason, we propose a special impression tray for oral implants. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a special impression tray for oral implants. Through the design of the first snap-fit ​​component and the second snap-fit ​​component, a detachable connection between the tray and the handle is achieved, so that the tray can be replaced separately without replacing the entire device, thereby reducing replacement costs, avoiding waste of parts such as the handle, and improving the maintainability and economy of the equipment.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a special impression tray for oral implants, comprising an impression tray main body, a handle is provided at the right end of the impression tray main body, a second clamping assembly is fixedly installed on the handle, the handle is connected to the tray through the second clamping assembly, a first clamping assembly is installed on the tray, and the tray is clamped with the side wall of the handle through the first clamping assembly.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Embodiment:

[0024] like Figure 1-4 As shown, a special impression tray for oral implantation comprises an impression tray body 1, a handle 2 is arranged at the right end of the impression tray body 1, a second clamping assembly 5 is fixedly mounted on the handle 2, the handle 2 is connected to the tray 3 via the second clamping assembly 5, a first clamping assembly 4 is mounted on the tray 3, and the tray 3 is clamped with the side wall of the handle 2 via the first clamping assembly 4;

[0025] The first clamping assembly 4 includes a clamping block 41 fixed on the right end side wall of the tray 3 and a polishing surface 42 arranged on the end of the clamping block 41;

[0026] The second engaging assembly 5 includes an inserting shaft 51 fixed on the end of the tray 3, a fixing plate 52 fixed on the outer wall of the handle 2, an inserting groove 53 provided in the handle 2 and extending into the fixing plate 52, a through hole 54 provided in the fixing plate 52, an auxiliary bin 55 fixed on the outer wall of the top end of the fixing plate 52, a slide groove 56 provided in the auxiliary bin 55, a slider 57 slidably connected to the slide groove 56, a limiting rod 58 inserted in the auxiliary bin 55 and fixedly connected to the slider 57, a spring 59 wound around the outer wall of the limiting rod 58, and a limiting groove 510 provided in the inserting shaft 51;

[0027] When the staff needs to remove the tray 3 from the handle 2, they only need to pull the limit rod 58 upwards so that the limit rod 58 slides upward in the slide groove 56 through the slider 57. One end of the spring 59 is connected to the inner wall of the auxiliary warehouse 55, and the other end of the spring 59 is connected to the outer wall of the slider 57. During the sliding process, the spring 59 is squeezed to deform until the inner end of the limit rod 58 moves from the limit groove 510 to the auxiliary warehouse 55. Two groups of slide grooves 56 are symmetrically opened in the auxiliary warehouse 55, and the length of each group of slide grooves 56 is set to be greater than the length of the through hole 54 and the limit groove 510. The length of each set of slide grooves 56 is greater than the sum of the lengths of the through hole 54 and the limit groove 510. The purpose of this arrangement is to ensure that when the limit rod 58 is pulled, the slider 57 can move smoothly, and the limit rod 58 can completely break away from the limit of the plug-in shaft 51, thereby releasing the limit of the plug-in shaft 51. At this time, the staff pulls the tray 3 outward, so that the tray 3 drives the plug-in shaft 51 to be pulled out of the plug-in groove 53, thereby driving the engaging block 41 to separate from the outer wall of the tray 3, and the disassembly is completed;

[0028] Similarly, when installation is required, it is only necessary to pull the limit rod 58 upward in advance so that the limit rod 58 moves into the auxiliary bin 55, and then the tray 3 drives the plug-in shaft 51 to plug into the plug-in slot 53 in the handle 2. The tray 3 simultaneously drives the two groups of engaging blocks 41 to contact the side walls of the handle 2. The polished surface 42 contacts the arc surface of the tray 3 to squeeze the two groups of engaging blocks 41 to expand outward and deform. Until the tray 3 drives the plug-in shaft 51 to be completely inserted into the plug-in slot 53, the two groups of engaging blocks 41 just form a clamping engagement with the side walls of the handle 2. At this time, the limit rod 58 is loosened and pulled, and the restoring force generated by the elasticity of the spring 59 itself pushes the limit rod 58 to restore, and the bottom end of the limit rod 58 passes through the through hole 54 and plugs into the limit slot 510 to form a fixation.

[0029] It is worth noting that there are two groups of snap-in blocks 41 symmetrically fixedly installed, and the spacing between the two groups of snap-in blocks 41 is set equal to the width of the left end of the handle 2. The snap-in blocks 41 are set as elastic bodies, and the snap-in blocks 41 are specifically set as polyurethane elastic parts. The polishing surface 42 of the left end of the handle 2 is set as an arc surface. In the special impression tray for oral implantation, there are two groups of snap-in blocks 41 symmetrically fixedly installed, and the spacing between the two groups of snap-in blocks is set equal to the width of the left end of the handle 2. The purpose of this design is to ensure that the snap-in blocks can be evenly squeezed and deformed during installation, so as to achieve a stable snap-in effect. The snap-in blocks are set as elastic bodies, and specifically adopt the material of polyurethane elastic parts, so that the snap-in blocks have certain flexibility and resilience, adapt to connecting parts of different shapes and sizes, and provide sufficient clamping force and fixity. In addition, the design that the polishing surface 42 of the left end of the handle 2 is set as an arc surface can ensure that during installation, the polishing surface 42 can evenly squeeze the two groups of snap-in blocks 41 to expand outward and deform after contacting the arc surface of the tray 3, so as to achieve a tight snap connection.

[0030] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model.
