Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a handle body, a medical handle, and a biopsy sampling device. Background Technology
[0002] A biopsy sampling device is a widely used medical instrument used for biopsy sampling and cell aspiration of pyramidal tumors and other tumors of unknown origin. It is suitable for biopsy sampling of various organs such as the kidneys, liver, lungs, breasts, thyroid glands, prostate, pancreas, testes, uterus, ovaries, and body surface.
[0003] Biopsy sampling devices typically include a detachably connected handle and a biopsy needle. The drive assembly inside the handle provides power for the movement of the biopsy needle. In order to achieve power transmission, the engagement point between the drive assembly and the biopsy needle needs to be exposed outside the handle.
[0004] During actual surgical procedures, the handpiece inevitably comes into contact with the patient's bodily fluids, such as blood and tissue fluid. Furthermore, when disinfecting the handpiece, chemical reagents such as alcohol and disinfectant are typically used. These two factors mean that liquids from the external environment may seep into the handpiece, causing corrosion or short circuits to internal electronic components or mechanical parts, leading to malfunction or failure of the handpiece.

[0055] In one embodiment of this utility model, the handle body 100 includes:
[0056] The shell structure 110 has a receiving space with an opening;
[0057] The partition structure 120 is located inside the receiving space and includes a side panel assembly 121 and a cover plate 122. The side panel assembly 121 is arranged around the periphery of the opening, and the cover plate 122 closes the end of the side panel assembly 121 away from the opening, so that the partition structure 120 divides the receiving space into an adjacent sealed cavity 1101 and an assembly groove 1102. The assembly groove 1102 communicates with the external environment through the opening.
[0058] The side panel assembly 121 is bonded and fixed to the cover plate 122 and sealed. At least one of the side panel assembly 121 and the cover plate 122 is provided with a bonding structure 123, and the bonding structure 123 is disposed between the side panel assembly 121 and the cover plate 122.
[0059] The handle body 100 of this utility model includes a housing structure 110 and a partition structure 120. The housing structure 110 has a receiving space with an opening. The partition structure 120 is disposed around the opening, dividing the receiving space into a sealed cavity 1101 and an assembly groove 1102 communicating with the opening. The housing structure 110 protects the components inside the sealed cavity 1101. The assembly groove 1102 communicates with the external environment through the opening and is used to receive the power output component of the drive assembly 200. The opening is used to expose part of the power output component. The partition structure 120 includes a side plate assembly 121 and a cover plate 122. The side plate assembly 121 is disposed around the opening. The cover plate 122 closes the end of the side plate assembly 121 away from the opening. The cover plate 122 and the side plate assembly 121 are sealed together by adhesive bonding, ensuring the sealing performance of the sealed cavity 1101 and preventing dust, liquids, etc. from the external environment from entering the sealed cavity 1101 through the assembly groove 1102. An adhesive bonding structure 123 is provided between the side plate assembly 121 and the cover plate 122. The adhesive bonding structure 123 can adopt grooves, protrusions, or textures to increase the bonding area and enhance the bonding effect, thereby improving the bonding strength between the side plate assembly 121 and the cover plate 122. This further prevents dust, liquids, etc. from the external environment from entering the sealed cavity 1101 from between the cover plate 122 and the side plate assembly 121, thus improving the waterproof and dustproof effect of the handle body 100. On the other hand, the probability of water entering the sealed cavity 1101 of the handle body 100 is small, so users do not need to take additional waterproof protection measures for the handle body 100 during use, improving the ease of use of the medical handle.
[0060] The adhesive structure 123 can be provided only on the side panel assembly 121, only on the cover plate 122, or on both the cover plate 122 and the side panel assembly 121.
[0061] In one embodiment, the adhesive structure 123 includes a first adhesive reservoir 1231 for containing adhesive.
[0062] The side panel assembly 121 has a first adhesive groove 1231 on its end face facing the cover plate 122; and / or, the cover plate 122 has a first adhesive groove 1231 on its end face facing the side panel assembly 121.
[0063] Reference Figures 2 to 4In this embodiment of the invention, the adhesive-bonding structure 123 includes a first adhesive-receiving groove 1231. The first adhesive-receiving groove 1231 allows for the addition of more adhesive and increases the contact area with the adhesive, thereby improving the bonding strength between the side panel assembly 121 and the cover plate 122, and enhancing the sealing performance between them. This prevents dust and liquids from the external environment from entering the sealing cavity 1101 through the assembly groove 1102, thus improving the waterproof and dustproof performance of the handle body 100. The first adhesive-receiving groove 1231 can be provided only on the end face of the side panel assembly 121 facing the cover plate 122, only on the end face of the cover plate 122 facing the side panel assembly 121, or on both the end faces where the cover plate 122 and the side panel assembly 121 are bonded. Specifically, in this embodiment, the first adhesive groove 1231 is provided on the end face of the side plate assembly 121 facing the cover plate 122, and is provided around the side plate assembly 121 to ensure that the side plate assembly 121 is tightly bonded to the cover plate 122 in all directions.
[0064] In one embodiment, the adhesive structure 123 includes a mesh structure 1232;
[0065] The mesh structure 1232 is disposed on the end face of the cover plate 122 facing the side plate assembly 121; and / or, the mesh structure 1232 is disposed on the end face of the side plate assembly 121 facing the cover plate 122.
[0066] Reference Figures 9 to 10 In this embodiment of the invention, the adhesive-bonding structure 123 includes a mesh structure 1232, which is formed by a plurality of elongated protrusions or grooves arranged in an alternating pattern. The mesh structure 1232 increases the contact area with the adhesive, thereby improving the bonding strength between the side panel assembly 121 and the cover plate 122, and enhancing the sealing performance between them. This prevents dust and liquids from the external environment from entering the sealing cavity 1101 through the assembly groove 1102, thus improving the waterproof and dustproof performance of the handle body 100. The mesh structure 1232 can be provided only on the end face of the side panel assembly 121 facing the cover plate 122, or only on the end face of the cover plate 122 facing the side panel assembly 121, or on both the end faces where the cover plate 122 and the side panel assembly 121 are in contact. In this specific embodiment, the mesh structure 1232 is disposed on the end face of the cover plate 122 facing the side plate assembly 121. Since the cover plate 122 has a large plane, the mesh structure 1232 is easy to arrange and has low processing difficulty.
[0067] In one embodiment, the side panel assembly 121 includes:
[0068] The first side plate 1211 is integrally formed with the shell structure 110. An assembly notch is formed between the first side plate 1211 and the shell structure 110, connecting the sealing cavity 1101 and the assembly groove 1102.
[0069] The second side plate 1212 is separately set from the shell structure 110. The second side plate 1212 is sealed to the periphery of the assembly notch to seal the assembly notch.
[0070] Combination Figures 2 to 4 In an embodiment of this utility model, the side plate assembly 121 includes a first side plate 1211 and a second side plate 1212. The first side plate 1211 is integrally formed with the housing structure 110, and the second side plate 1212 is separately formed with the housing structure 110. Specifically, the opening is rectangular. The first side plate 1211 and the second side plate 1212 together form the four side walls of the assembly groove 1102. Among them, the first side plate 1211, which is integrally formed with the housing structure 110, forms three side walls, and the second side plate 1212, which is separately formed with the housing, forms one side wall. Specifically, in this embodiment, the driving assembly 200 of the medical handle passes through the second side plate 1212, such that a part of the driving assembly 200 is located in the assembly groove 1102, and another part is located in the sealing cavity 1101.
[0071] Specifically, in this embodiment, during the assembly of the medical handle, the drive assembly 200 is first assembled with the second side plate 1212, and then the second side plate 1212 is assembled at the assembly notch. A sealing connection between the second side plate 1212 and the assembly notch is achieved by setting a sealing sheet or applying sealant, so that the second side plate 1212 and the first side plate 1211 form a complete side plate assembly 121. Then, the cover plate 122 is snapped and glued onto the side plate assembly 121. By integrally molding the first side plate 1211 with the shell structure 110, the number of parts requiring assembly is reduced, improving assembly convenience and enhancing the connection strength and sealing performance between the side plate assembly 121 and the shell structure 110. By separately configuring the second side plate 1212 and the shell structure 110, it is convenient to have one part of the drive assembly 200 located in the assembly groove 1102 and the other part in the sealing cavity 1101, reducing the assembly difficulty of the medical handle.
[0072] Combination Figure 1 , Figure 3 and Figure 5In one embodiment, the housing structure 110 includes an upper housing 111 and a lower housing 112. The upper housing 111 and the lower housing 112 are sealed together and together form a receiving space. An opening is located in the lower housing 112. The partition structure 120 is integrally formed with the lower housing 112, reducing the processing difficulty of the housing structure 110. Specifically, in this embodiment, the upper housing 111 and the cover plate 122 are fixed by screws or snap-fitting. While the upper housing 111 and the lower housing 112 are fastened together, the cover plate 122 is fastened to the side plate assembly 121, achieving adhesive fixation between the cover plate 122 and the side plate assembly 121, reducing assembly steps.
[0073] This utility model also proposes a medical handle, comprising:
[0074] The aforementioned handle body 100; and
[0075] The drive assembly 200 passes through the side plate assembly 121 and is sealed to the side plate assembly 121. At least a portion of the drive assembly 200 is located in the sealed cavity 1101. The power output component of the drive assembly 200 is located in the assembly groove 1102, and a portion of the power output component is exposed outside the opening.
[0076] The specific structure of the handle body 100 is as described in the above embodiments. Since this medical handle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here. The power output component of the drive assembly 200 is located within the mounting groove 1102, and part of the power output component is exposed outside the opening, facilitating connection and power transmission with the components driven by the medical handle. The other parts of the power output component pass through the side plate assembly 121 and are arranged within the sealed cavity 1101, reducing the possibility of contamination by dust and liquids in the external environment and extending the service life of the drive assembly 200.
[0077] In one embodiment, the drive assembly 200 includes a drive shaft 210 rotatably passing through the side plate assembly 121 to extend from the sealing cavity 1101 to the mounting groove 1102, and the drive shaft 210 is sealed to the side plate assembly 121.
[0078] In an embodiment of this utility model, the drive assembly 200 includes a rotatable drive shaft 210. The drive shaft 210 extends from the sealed cavity 1101 through the side plate assembly 121 into the mounting groove 1102. Since the drive shaft 210 rotates, a dynamic seal is used to seal the drive shaft 210 and the side plate assembly 121, for example, by providing an O-ring or lip seal on the outside of the drive shaft 210. This sealed connection between the drive shaft 210 and the side plate assembly 121 prevents dust and liquids from the external environment from entering the sealed cavity 1101 from around the drive shaft 210, further improving the waterproof and dustproof performance of the medical handle.
[0079] In one embodiment, the side plate assembly 121 is provided with a first shaft hole, and the drive shaft 210 is rotatably inserted through the first shaft hole. The medical handle also includes a first seal 300, which is sleeved on the outside of the drive shaft 210, abuts against the side plate assembly 121, and seals the first shaft hole.
[0080] Reference Figure 11 and Figure 12 In this embodiment of the present invention, the drive shaft 210 rotatably passes through the first shaft hole provided on the side plate assembly 121. A first sealing element 300 is provided on the drive shaft 210. The first sealing element 300 can be an O-ring or a lip seal, etc. The first sealing element 300 abuts against the side plate assembly 121 and seals the first shaft hole. Even if the first sealing element 300 rotates with the drive shaft 210, it does not affect the sealing of the first shaft hole by the first sealing element 300, thereby achieving dynamic sealing between the drive shaft 210 and the side plate assembly 121. The structure is simple and the cost is low.
[0081] In one embodiment, the side plate assembly 121 has a receiving groove 12121 for receiving lubricating medium on the side facing the sealing cavity 1101, a first shaft hole is provided in the bottom wall of the receiving groove 12121, and a first seal 300 is at least partially provided inside the receiving groove 12121.
[0082] Reference Figure 12 In this embodiment of the invention, a receiving groove 12121 is provided on the side of the side plate assembly 121 facing the sealing cavity 1101. The receiving groove 12121 is used to add a lubricating medium, such as grease or graphite lubricant. The first seal 300 may be partially or completely located in the receiving groove 12121. During the rotation of the first seal 300 with the drive shaft 210, the first seal 300 will rub against the inner wall of the receiving groove 12121. Increasing the lubricating medium reduces friction and helps extend the service life of the first seal 300. On the other hand, due to the obstruction of the lubricating medium, dust and liquids from the external environment are less likely to enter the sealing cavity 1101, further improving the dustproof and waterproof effect of the medical handle.
[0083] Specifically, in this embodiment, the receiving groove 12121 includes a first sub-groove and a second sub-groove that are connected to each other. The second sub-groove is close to the assembly groove 1102. The first sealing member 300 is disposed inside the second sub-groove. The inner diameter of the first sub-groove is larger than the inner diameter of the second sub-groove, which facilitates the addition of lubricating medium. The end of the motor 230 blocks the groove opening of the first sub-groove facing the sealing cavity 1101 to prevent the lubricating medium from leaking into the sealing cavity 1101.
[0084] In one embodiment, the drive assembly 200 further includes a support shaft 220, which is at least partially disposed within the mounting groove 1102 and fixedly passes through the side plate assembly 121.
[0085] Reference Figure 8 In this embodiment of the invention, the drive assembly 200 further includes a fixed support shaft 220, which is fixed in the assembly groove 1102. For ease of assembly, one end of the support shaft 220 passes through the side plate assembly 121. Therefore, the drive shaft 210 and the side plate assembly 121 are sealed together by a static seal, such as by setting a sealing ring or applying sealant to the outside of the drive shaft 210. The sealed connection between the support shaft 220 and the side plate assembly 121 prevents dust and liquids from the external environment from entering the sealed cavity 1101 from around the support shaft 220, further improving the waterproof and dustproof performance of the medical handle.
[0086] In one embodiment, the side plate assembly 121 is provided with a second shaft hole, and the support shaft 220 is fixedly inserted through the second shaft hole;
[0087] The support shaft 220 has at least one of the outer wall and the inner wall of the second shaft hole, which is provided with a second adhesive groove 221. The second adhesive groove 221 is used to contain adhesive so that the side plate assembly 121 is bonded and fixed to the support shaft 220 and sealed. Alternatively, the medical handle also includes a second seal 400, which is disposed between the outer wall of the support shaft 220 and the inner wall of the second shaft hole to seal the connection between the support shaft 220 and the side plate assembly 121.
[0088] Reference Figure 6 and Figure 7In this embodiment of the invention, the support shaft 220 passes fixedly through the second shaft hole provided on the side plate assembly 121. A second adhesive groove 221 can be provided on the outer wall of the support shaft 220, or on the inner wall of the second shaft hole, or both the outer wall of the support shaft 220 and the inner wall of the second shaft hole can be provided. By adding adhesive to the second adhesive groove 221, the support shaft 220 is firmly bonded to the side plate assembly 121, forming a seal. The structure is simple and easy to process.
