Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to an assembled anal dilator. Background Technology

[0002] An anal dilator (also known as an anal expander or anal splinter) is a medical device primarily used to enlarge the opening of the anus and lower rectum during certain medical examinations, treatments, or surgeries, so that doctors can see the internal condition more clearly or operate more easily.

[0003] Chinese patent document CN102000387B discloses an anal dilator for dilating the anus and anal canal. It includes a cylindrical body and an outwardly wide side, with the wide side located at the proximal end of the body. The feature is that a hollow anal dilator cap is provided at the distal end of the body. The anal dilator cap includes a frustum-shaped dilator portion located at its proximal end, a conical guide portion located at its distal end, and a connecting portion located between the dilator portion and the guide portion. The maximum outer diameter of the anal dilator cap is smaller than the outer diameter of the body.

[0004] However, existing anal dilators have the following shortcomings in practical use: In situations such as enemas, when fluid is continuously introduced through the catheter, the dilator may need to be temporarily removed from the patient's body. However, because the dilator is a complete structure, the catheter must be removed from the patient's body first before the dilator can be removed, and then the catheter can be reinserted. Therefore, this catheter insertion method increases patient discomfort. To solve this problem, the assembled anal dilator of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an assembled anal dilator that can be directly removed without the need to pull out the catheter.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An assembled anal dilator, comprising:

[0008] Two semi-cylinders, each with an expanded edge at one end and an arc-shaped groove on each. One of the semi-cylinders has a limiting groove on each side edge of the arc-shaped groove, and the other of the semi-cylinders has a limiting step on each side edge of the arc-shaped groove. The inner wall of the limiting groove also has a locking groove, and a locking protrusion is provided at the connection between the locking groove and the limiting groove. A buckle is provided on the limiting step.

[0009] When the two semi-cylinders are used to fasten each other, the limiting step is adapted to be accommodated in the limiting groove, and the fastening block slides into the slot. When the two semi-cylinders slide relative to each other, the fastening block is engaged with or moved away from the slot protrusion.

[0010] Optionally, each of the limiting grooves has two card slots, and there is a gap between the two card slots.

[0011] Optionally, each of the limiting steps is provided with two buckles, and the distance between the two buckles is equal to the distance between the two slots.

[0012] Optionally, a gripping block is also provided on the extended edge.

[0013] Optionally, the semi-cylinder is made of plastic.

[0014] Optionally, the semi-cylinder, the extended edge, and the grip block are integrally formed.

[0015] Optionally, the semi-cylinder is also provided with a perforated hole.

[0016] Optionally, the outer diameter of the semi-cylinder gradually decreases along a direction away from the expanding edge.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] This utility model discloses an assembled anal dilator, comprising two semi-cylinders, each with an expanded edge at one end and an arc-shaped groove on each semi-cylinder. One of the semi-cylinders has a limiting groove on each side edge of the arc-shaped groove, and the other has a limiting step on each side edge of the arc-shaped groove. The inner wall of the limiting groove also has a locking groove, and a locking protrusion is provided at the connection between the locking groove and the limiting groove. A buckle is provided on the limiting step. When the two semi-cylinders are used to interlock, the limiting step is fitted into the limiting groove, and the buckle slides into the locking groove. When the two semi-cylinders slide relative to each other, the buckle engages with or moves away from the locking protrusion. Thus, when the assembled anal dilator of this application is inserted into the patient's anus during actual use, the medical catheter is also inserted into the patient's body between the two arc-shaped grooves. When it is necessary to remove the anal dilator, the two semi-cylinders are simply slid a certain distance apart so that the buckle disengages from the locking protrusion, and the two semi-cylinders can be separated. This allows the anal dilator to be removed without removing the medical catheter, making it convenient to use. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] like Figures 1 to 3 As shown, in one embodiment, an assembled anal dilator 10 includes two semi-cylinders 100. Each semi-cylinder 100 has an expanding edge 200 at one end. Each semi-cylinder 100 has an arc-shaped groove 110. One of the semi-cylinders 100 has a limiting groove 120 on each side edge of the arc-shaped groove 110. The other semi-cylinder 100 has a limiting step 130 on each side edge of the arc-shaped groove 110. The inner wall of the groove 120 is also provided with a slot 140. A locking protrusion 150 is provided at the connection position between the slot 140 and the limiting groove 120. A buckle 160 is provided on the limiting step 130. When the two semi-cylinders 100 are used to fasten each other, the limiting step 130 is adapted to be accommodated in the limiting groove 120, and the buckle 160 slides into the slot 140. When the two semi-cylinders 100 slide relative to each other, the buckle 160 is engaged with or moved away from the locking protrusion 150.

[0030] It should be noted that the assembled anal dilator 10 of this application is an assembled structure, which can be easily disassembled and assembled. Specifically, an arc-shaped groove 110 is provided on the semi-cylinder 100, and an expanding edge 200 is provided at its end. Thus, the expanding edge 200 facilitates the insertion of the anal dilator into the patient's body by medical staff. Furthermore, limiting grooves 120 are provided on both sides of the arc-shaped groove 110 of one semi-cylinder 100, and limiting steps 130 are provided on both sides of the arc-shaped groove 110 of the other semi-cylinder 100. Thus, when the two semi-cylinders 100 are fastened together, the two limiting steps 130 are respectively accommodated in the two limiting grooves 120. In this way, through the cooperation of the limiting steps 130 and the limiting grooves 120, the two semi-cylinders 100 can be fastened together quickly and accurately. Furthermore, a retaining groove 140 is also provided on the semi-cylinder 100 with the limiting groove 120, wherein the retaining groove 140 is located on the inner wall of the limiting groove 120. Furthermore, a retaining protrusion 150 is provided at the junction of the retaining groove 140 and the limiting groove 120. Furthermore, a latching block 160 is also provided on the semi-cylinder 100 with the limiting step 130. Thus, when the two semi-cylinders 100 are fastened together, the two limiting steps 130 are respectively accommodated in the two limiting grooves 120, and simultaneously, the latching block 160 slides into the retaining groove 140. When the two semi-cylinders 100 are subjected to an external force and slide against each other, the latching block 160 engages with the retaining protrusion 150, ensuring that the two semi-cylinders 100 are reliably fastened as a whole. When the latching block 160 disengages from the retaining protrusion 150, the two semi-cylinders 100 can be separated. Thus, when the assembled anal dilator 10 of this application is inserted into the patient's anus during actual use, the medical catheter is also inserted into the patient's body between the two arc-shaped grooves 110. When it is necessary to remove the anal dilator, the two semi-cylinders 100 are simply slid a certain distance apart so that the buckle 160 disengages from the locking protrusion 150, and the two semi-cylinders 100 can be separated. This allows the anal dilator to be removed without removing the medical catheter, making it convenient to use.

[0031] like Figure 2 and Figure 3 As shown, in one embodiment, each limiting groove 120 has two slots 140, and there is a gap between the two slots 140. Each limiting step 130 has two fastening blocks 160, and the distance between the two fastening blocks 160 is equal to the distance between the two slots 140.

[0032] It should be noted that there are two spaced-apart slots 140 and fasteners 160 on either side of the arc-shaped groove 110. Thus, when the two semi-cylinders 100 are fastened together, each side of the semi-cylinder 100 is engaged with the two slot protrusions 150 in the slots 140 by the two fasteners 160, so that the two semi-cylinders 100 can be reliably fastened and fixed.

[0033] like Figure 1 As shown, in one embodiment, a gripping block 300 is also provided on the extended edge 200. Thus, the gripping block 300 extends outward along the radial direction of the semi-cylinder 100, making it convenient for medical staff to grip the semi-cylinder 100.

[0034] In one embodiment, the semi-cylinder 100 is made of plastic. Further, in another embodiment, the semi-cylinder 100, the expanded edge 200, and the grip 300 are integrally molded. This ensures sufficient structural strength among the semi-cylinder 100, the expanded edge 200, and the grip 300. By using a plastic material for the assembled anal dilator 10 of this application, as a disposable medical device, manufacturing costs can be effectively reduced, while avoiding the risk of cross-infection from sharing among patients.

[0035] In one embodiment, the semi-cylinder 100 is also provided with a perforation. This perforation allows medical staff to easily administer medication to the patient's lesion site.

[0036] like Figure 1 As shown, in one embodiment, the outer diameter of the semi-cylinder 100 gradually decreases along the direction away from the expanding edge 200.

[0037] Thus, the outer diameter of the end of the semi-cylinder 100 away from the expanding edge 200 is small, and the outer diameter of the end of the semi-cylinder 100 close to the expanding edge 200 is large, so that the outer diameter of the assembled anal dilator has a structure that is smaller in the front and larger in the back. This makes it easier to insert the assembled anal dilator 10 of this application into the patient's anus. During the insertion process, the sphincter of the patient's anus can gradually expand, avoiding the problem of strain due to violent expansion.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
