Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a scoop for removing residual tophi during surgery. Background Technology

[0002] During gout surgery, gouty tophi often cannot be completely removed in one session, requiring careful removal of any remaining tophi. Currently, surgeons mostly use a curette to manually scrape away these remaining tophi. However, using a curette to remove residual tophi has several drawbacks. For example, during scraping, residual tophi easily adhere to the curette surface, requiring frequent cleaning, which is cumbersome and affects surgical efficiency. Furthermore, the curette's relatively long blade makes it difficult to precisely scrape areas with residual tophi, potentially leading to incomplete removal and impacting the surgical outcome. Utility Model Content

[0003] The purpose of this invention is to provide a scoop for removing residual tophi during surgery, which improves the efficiency of removing residual tophi during gout surgery and has a good removal effect.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A scoop for removing residual tophi during surgery, comprising a scoop head and a connecting handle;

[0006] The spoon head is a transparent spherical structure, and there is a receiving cavity inside the spoon head. The bottom of the spoon head has a cleaning port for removing residual tophi, and the cleaning port is connected to the receiving cavity.

[0007] The front end of the connecting handle is fixed to the rear side of the spoon head. A negative pressure channel is provided inside the connecting handle, the front end of the negative pressure channel is connected to the receiving cavity, and the rear end of the negative pressure channel is used to connect to an external negative pressure device.

[0008] The outer wall of the connecting handle is also provided with a water inlet for connecting an external water injection device, and the water inlet is also connected to the negative pressure channel.

[0009] Compared with the prior art, the advantages of this utility model are:

[0010] 1. By setting a transparent spoon head, a cleaning port, an annular convex edge, and a receiving cavity, the operator can clearly observe the position of the cleaning port and the state inside the receiving cavity, so that the operator can accurately position the residual tophi during the operation and quickly remove them through the blade, thus improving the efficiency and accuracy of surgical removal.

[0011] 2. By setting up a accommodating cavity, a negative pressure channel connected to the accommodating cavity, and an external negative pressure device, the removed residual tophi can be drawn into the negative pressure channel. In conjunction with the external water injection device and water inlet, liquid is injected into the negative pressure channel, which enhances the fluidity of the residual tophi in the negative pressure channel, thereby quickly removing and collecting the residual tophi. This avoids the need for frequent cleaning of instruments during the traditional removal process and improves the efficiency of the operation. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0018] like Figure 1-4 The image shown is a schematic diagram of an embodiment of a scoop for removing residual tophi during surgery provided by this utility model:

[0019] A scoop for removing residual tophi during surgery, comprising a scoop head 1 and a connecting handle 2;

[0020] The spoon head 1 is a transparent spherical structure, and the spoon head 1 has a receiving cavity inside. The bottom of the spoon head 1 has a cleaning port 3 for removing residual tophi, and the cleaning port 3 is connected to the receiving cavity.

[0021] The front end of the connecting handle 2 is fixed to the rear side of the spoon head 1. The connecting handle 2 is provided with a negative pressure channel 4 that runs through the front and rear. The front end of the negative pressure channel 4 is connected to the accommodating cavity, and the rear end of the negative pressure channel 4 is used to connect to an external negative pressure device.

[0022] The outer wall of the connecting handle 2 is also provided with a water inlet 5 for connecting an external water injection device, and the water inlet 5 is also connected to the negative pressure channel 4.

[0023] It should be further noted that the external water injection device and the external negative pressure device are both existing devices on the market, so no further details will be provided here. The external water injection device is connected to the water inlet 5 through the water injection pipe 201, and the external negative pressure device is connected to the rear end of the negative pressure channel 4 through the exhaust pipe 202.

[0024] In this embodiment, the spoon head 1 is a spherical structure, the cleaning port 3 is circular, and the cleaning port 3 is located at the bottom center of the spoon head 1. In some embodiments, the spoon head 1 may also be rugby ball shaped.

[0025] The bottom of the spoon head 1 is provided with an annular protrusion 6 corresponding to the cleaning port 3. The annular protrusion 6 extends downward and is used to assist in aligning the residual tophi to be removed.

[0026] The outer periphery of the cleaning port 3 is provided with a cutting edge.

[0027] The outer wall surface of the connecting handle 2 is provided with an anti-slip structure 7 for easy gripping. In this embodiment, the anti-slip structure 7 is a sleeve fitted on the outer wall surface of the rear section of the connecting handle 2. The sleeve has anti-slip texture. In some embodiments, the anti-slip structure 7 can be selected as grooves, protrusions, and surface textures.

[0028] The spoon head 1 is made of polycarbonate or polypropylene. Specifically, the spoon head 1 is made of transparent material so that the operator can clearly observe the state of the removal opening 3 and the cavity, so as to accurately remove the residual tophi during the operation.

[0029] The general method of using this utility model is as follows:

[0030] During the procedure, the surgeon holds the connecting handle 2 and aligns the removal port 3 of the spoon head 1 with the residual tophi on the bone or joint surface, then removes the residual tophi through the blade. The removed residual tophi first enter the receiving cavity inside the spoon head 1, and then, under the action of an external negative pressure device, are drawn into the negative pressure channel 4 of the connecting handle 2. Simultaneously, liquid is injected into the negative pressure channel 4 through the water inlet 5 of an external water injection device, enhancing the fluidity of the residual tophi within the negative pressure channel 4, allowing them to be smoothly drawn away and collected by the external negative pressure device, thus improving surgical efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
