Description

Technical Field

[0001] This utility model relates to the field of instrument brush technology, specifically to an instrument brush with a replaceable brush head. Background Technology

[0002] In the cleaning of large precision instruments, in order to achieve comprehensive cleaning of different instruments, different types of instrument brushes are generally used to clean different instruments and different parts of the instruments.

[0003] Currently, medical device brushes on the market are mainly divided into two types: integrated and replaceable. Integrated medical device brushes have the brush head and handle fixedly connected. When the brush head is worn, aged, or the brush head specifications need to be changed for different types of instruments, the whole brush needs to be discarded and replaced with a new one. This not only leads to the waste of non-worn parts such as the handle and increases the cost of use, but also generates a large amount of waste plastic and other pollutants, which is not in line with the development trend of energy conservation and environmental protection.

[0004] While existing replaceable instrument brushes have solved the waste problem of one-piece designs, they have many shortcomings in structural design: First, most use threaded connections, snap-fit ​​fasteners, or other fixing methods, requiring manual rotation or forceful insertion and removal when changing brush heads, which is cumbersome; Second, they lack versatility, with most clamping structures only compatible with brush handles of specific sizes. When different types of instruments need to be cleaned and different brush heads need to be changed, special handles are often required, and too many brushes need to be prepared during the cleaning process. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable brush head for a medical brush, in order to solve the technical problems of limited adjustment range of clamping degree and difficulty in adapting to the fixing requirements of brush handles of different thicknesses in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: A replaceable brush head instrument brush, comprising: Circular ring; Two semi-cylindrical handles, each with a semi-cylindrical end attached to the same side end; A rotating shaft is provided on the handle end on the outer side of the end head. Both handles are connected to the side wall on the same side of the ring through the rotating shaft. The two handles are arranged in a mirror symmetrical manner. The clamping head includes two mirror-symmetrical clamping plates, which are arranged parallel to the cutting plane of the handle. The outer end of each clamping plate is connected to the outer end of the end head through a connector, and a clamping gap is formed between the two clamping plates. The handle is rotatable around the rotating axis to the axial direction of the ring, so that the outer wall of the end and the inner wall of the ring come into contact, and the two clamping plates are close to each other to hold the brush handle of the brush head.

[0007] As a preferred embodiment of this utility model, a slot is provided in the middle of the two ends of the grips facing the clamp plate. The slot is perpendicular to the cutting plane of the grip along the length direction of the grip, and the slot is open on both the surface and the cutting plane of the end of the grip.

[0008] As a preferred embodiment of this utility model, a semi-threaded post is provided at the ends of the two grips away from the end head. The cross-sectional planes of the two semi-threaded posts cooperate to form a stud, and the two semi-threaded posts are threadedly connected by a nut.

[0009] As a preferred embodiment of this utility model, a positioning groove is provided on the surface of the clamp plate to cooperate with the brush handle of the brush head.

[0010] Compared with the prior art, this utility model has the following advantages: This invention utilizes a rotating shaft, a handle, and a ring to create a mechanism that allows for the clamping and disassembly of the brush head simply by rotating the handle around the rotating shaft. When the handle is rotated to the axial direction of the ring, the two clamping plates approach each other and clamp the brush handle. Rotating the handle in the opposite direction separates the clamping plates, allowing the old brush head to be removed and replaced with a new one. The entire process requires no tools, is simple to operate, and improves the efficiency of brush head replacement. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 and Figure 2 As shown, this utility model provides a replaceable brush head instrument brush, comprising: Ring 10; Two semi-cylindrical handles 20, each with a semi-cylindrical end 11 connected to the same side end of the two handles 20; The rotating shaft 30 is located on the end of the handle 20 on the outer side of the end 11. Both handles 20 are connected to the side wall of the same side of the ring 10 through the rotating shaft 30. The two handles 20 are arranged in a mirror symmetrical manner. In conjunction with the rotating shaft 30, the handle 20 can rotate around the shaft to achieve a clamping action similar to "pliers", improving operating efficiency and saving effort.

[0016] The clamping head 40 includes two mirror-symmetrical clamping plates 41, which are parallel to the cutting plane of the handle 20. The outer end of each clamping plate 41 is connected to the outer end of the end head 11 via a connector 43, forming a clamping gap between the two clamping plates 41. The two mirror-symmetrical clamping plates 41 form a stable clamping structure, reliably fixing the brush head handle and preventing it from loosening or falling off during cleaning. The parallel design of the clamping plates to the cutting plane of the handle ensures that the brush head handle is evenly clamped, avoiding damage caused by uneven force. The connection to the end head 11 via the connector 43 allows the rotation of the handle to be precisely converted into the opening and closing of the clamping plates, making operation intuitive and simple.

[0017] The handle 20 can rotate around the rotation axis 30 to the axial direction of the ring 10, so that the outer wall of the end 11 contacts the inner wall of the ring 10, and the two clamping plates 41 clamp the brush head handle close to each other. This allows the handle 20 to rotate freely around the axis, precisely controlling the opening and closing degree of the clamping plates 41 to accommodate brush head handles of different diameters. It also allows the brush head to adjust its direction in three-dimensional space, facilitating the cleaning of medical devices at different angles and positions, and improving the cleaning coverage.

[0018] A slot 50 is provided in the middle of the ends of the two grips 20 facing the clamp plate 41. The slot 50 is along the length of the grip 20 and perpendicular to the cutting plane of the grip 20. The slot 50 is open on both the surface and the cutting plane of the end of the grip 20. The slots 50 on the two grips 20 are in the same vertical position and form a cross groove structure with the cutting plane of the two grips 20.

[0019] This means that when the brush handle is long, the brush handle can be inserted into the slot 50 through the clamping gap between the two clamping plates 41 or into the cross-groove structure according to the structure of the brush handle. Then, with the clamping cooperation of the two clamping plates 41, the brush handle of the brush head can be clamped in multiple segments, which further improves the tightness and the adaptability of the brush head.

[0020] Each of the two grips 20 is provided with a semi-threaded post 21 at the end away from the end 11. The cutting planes of the two semi-threaded posts 21 fit together to form a stud, and the two semi-threaded posts 21 are threaded together by a nut 22. The two semi-threaded posts fit together to form a complete stud. After being tightened by the nut 22, the grip 20 is locked in a specific position to prevent accidental loosening.

[0021] The opening and closing degree of the handle can be precisely controlled by rotating the nut 22, thereby adjusting the clamping force of the clamp 41 on the brush head, adapting to brush head handles of different materials and thicknesses. Simply loosening the nut will immediately release the lock, enabling quick brush head replacement and improving work efficiency.

[0022] The surface of the clamping plate 41 is provided with a positioning groove 42 that matches the brush handle of the brush head. The groove matches the specific shape of the brush handle to ensure that the brush head is installed in the correct position, avoids displacement that affects the cleaning effect, prevents the brush head from rotating during use, and ensures that the bristles always face the correct direction, thereby improving cleaning efficiency. The positioning groove 42 fits tightly with the brush handle, increases the contact area, improves clamping stability, and prevents the brush head from loosening during strong cleaning.

[0023] This implementation method enables rapid replacement of brush heads without replacing the entire brush, significantly reducing the preparation time for cleaning medical devices. One handle can be adapted to multiple brush heads, reducing the procurement and inventory costs of medical equipment, while extending the lifespan of the handle. Multi-angle adjustment combined with stable clamping ensures that every corner of the medical device is thoroughly cleaned, improving the success rate of disinfection and sterilization.

[0024] In this embodiment, a raised ridge 60 can be provided on the outer side wall of the grip 20, and a finger-fitting groove 70 that biomimetically matches the fingertip can be provided on the raised ridge 60 to improve grip comfort.

[0025] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
