[0042] This utility model proposes a medical handle.

[0043] Please see Figures 1 to 4 , Figure 1 A cross-sectional view of an embodiment of the medical handle provided by this utility model. Figure 1 , Figure 2 for Figure 1 A magnified view of a portion of point A in the middle. Figure 3This is a cross-sectional view of a partial structure of an embodiment of the medical handle provided by this utility model. Figure 4 A schematic diagram of the structure of the first sub-shell of the housing of the handle assembly of the medical handle provided by this utility model.

[0044] In one embodiment of this utility model, the medical handle includes:

[0045] The handle assembly 100 includes a housing 110 and a partition 120. The housing 110 has a sealed cavity 101 and an assembly groove 102 that are adjacent to each other and separated by the partition 120. The groove of the assembly groove 102 is opened on the housing 110 and communicates with the outside of the housing 110.

[0046] The drive assembly 200 passes through the partition 120 and is sealed to the partition 120. At least a portion of the drive assembly 200 is disposed in the sealed cavity 101. The power output component 201 of the drive assembly 200 is disposed in the assembly groove 102, and at least a portion of the power output component 201 is exposed in the groove opening.

[0047] The medical handle of this utility model includes a handle assembly 100 and a drive assembly 200. The handle assembly 100 includes a housing 110 and a partition 120. The housing 110 has a sealing cavity 101 and an assembly groove 102. The partition 120 separates the sealing cavity 101 and the partition 120. The drive assembly 200 passes through the partition 120 and is sealed to the partition 120, so that a part of the drive assembly 200 is located in the sealing cavity 101 and is protected by the handle assembly 100, reducing the possibility of damage. The power output component 201 of the drive assembly 200 is located in the assembly groove 102, and part of the power output component 201 is exposed at the opening of the assembly groove 102. When the biopsy needle is assembled onto the medical handle, the opening of the assembly groove 102 faces the biopsy needle, and the power output component 201 drives the power input component connected to the biopsy needle, realizing the medical handle driving the biopsy needle. The sealed connection between the drive assembly 200 and the partition 120 reduces the possibility of liquids, dust, etc. from the external environment entering the sealed cavity 101 through the periphery of the drive assembly 200, improves the waterproof performance of the medical handle, thereby ensuring that the sealed cavity 101 is dry and clean, reduces the possibility of short circuits or malfunctions of the components in the sealed cavity 101, and extends the service life of the medical handle.

[0048] The sealing connection between the drive assembly 200 and the partition 120 can be achieved by setting a sealing ring, applying sealant, or other methods.

[0049] In one embodiment, the driving component 200 further includes:

[0050] At least one rotating shaft 210 and a first sealing member 220 sleeved on the corresponding rotating shaft 210, the partition portion 120 is provided with a first shaft hole 1221, the rotating shaft 210 is rotatably inserted through the corresponding first shaft hole 1221, and the first sealing member 220 seals the gap between the first shaft hole 1221 and the rotating shaft 210.

[0051] Combination Figures 2 to 7 In an embodiment of this utility model, the medical handle is applied to a biopsy sampling device. The drive assembly 200 includes two motors, two rotating shafts 210, two first seals 220, two drive gears 240, two transmission gears 250, and a support shaft 230. The two motors are disposed in the sealing cavity 101, and each motor drives and connects to one rotating shaft 210. The rotating shaft 210 extends through the first shaft hole 1221 on the partition 120 into the assembly groove 102. Each rotating shaft 210 is located in the assembly groove 102. One end of the 02 is provided with a drive gear 240, the support shaft 230 is fixed in the assembly groove 102, and two transmission gears 250 are rotatably sleeved on the outside of the support shaft 230. Each drive gear 240 meshes with a transmission gear 250. The transmission gear 250 is the power output component 201, which is used to mesh with the power input component on the biopsy needle. The rotation of the motor drives the drive gear 240 to rotate through the rotating shaft 210, and the drive gear 240 drives the transmission gear 250 to rotate, thereby driving the biopsy needle to move. The first seal 220 seals the gap between the first shaft hole 1221 and the rotating shaft 210, preventing liquid from the external environment from entering the sealing cavity 101 from the assembly groove 102. The first seal 220 can be disposed between the inner wall of the first shaft hole 1221 and the outer wall of the rotating shaft 210, respectively sealing and contacting the inner wall of the first shaft hole 1221 and the outer wall of the rotating shaft 210; the first seal 220 can also be disposed outside the rotating shaft 210, with the side wall of the first seal 220 sealing and contacting the periphery of the first shaft hole 1221.

[0052] In one embodiment, the first seal 220 is disposed in the assembly groove 102, and an axial limiting member is provided on the rotating shaft 210. One end of the first seal 220 abuts against the axial limiting member, and the other end of the first seal 220 abuts against the partition portion 120 and covers the first shaft hole 1221.

[0053] Reference Figure 5In this embodiment of the invention, the first sealing element 220 is disposed within the assembly groove 102, which greatly reduces the possibility of liquids, dust, etc., passing through the first shaft hole 1221. This better seals the rotating shaft 210 and the first shaft hole 1221, further improving the waterproof performance of the medical handle and extending its service life. An axial limiting element is provided on the rotating shaft 210 to axially position the first sealing element 220, preventing axial movement of the first sealing element 220 on the rotating shaft 210 that could lead to sealing failure and ensuring the sealing effect of the first sealing element 220. The axial limiting element can be implemented in various forms such as a shoulder or a retaining ring.

[0054] In one embodiment, the first seal 220 includes a main body 221 and a lip 222 disposed on the main body 221. The main body 221 is sleeved on the outside of the rotating shaft 210 and is press-fitted with the rotating shaft 210. The lip 222 abuts against the partition 120 and covers the first shaft hole 1221.

[0055] Reference Figure 2 and Figure 8 The first sealing element 220 includes a main body 221 and a lip 222. The main body 221 is fitted onto the outside of the rotating shaft 210 and is press-fitted with the rotating shaft 210. The lip 222 is disposed on one side of the main body 221 and extends obliquely away from the rotating shaft 210. The end of the lip 222 away from the main body 221 abuts against the partition portion 120. When the first sealing element 220 rotates with the rotating shaft 210, the lip 222 rotates on the partition portion 120 and always covers the first shaft hole 1221, thereby preventing liquids and dust from the external environment from passing through the first shaft hole 1221. Furthermore, the contact area between the lip 222 and the partition portion 120 is small, resulting in less resistance to the rotation of the rotating shaft 210 and minimal impact on the output torque of the medical handle. Specifically, the first sealing element 220 is a V-shaped sealing ring, such as a VA-type sealing ring, a VS-type sealing ring, or a VL-type sealing ring. In this embodiment, a VA-type sealing ring is used.

[0056] In one embodiment, the drive assembly 200 further includes a support shaft 230, the partition portion 120 is provided with a second shaft hole 1222, and the support shaft 230 is fixedly inserted through the second shaft hole 1222 and sealed to the second shaft hole 1222.

[0057] Combination Figures 2 to 7In this embodiment of the invention, a second shaft hole 1222 is provided on the partition portion 120. One end of the support shaft 230 is fixed in the second shaft hole 1222, and the other end is fixed to the inner wall of the assembly groove 102 opposite to the partition portion 120. The support shaft 230 passing through the second shaft hole 1222 makes the structure of the medical handle more compact and reduces the possibility of radial runout of the support shaft 230, thereby improving the stability of the support shaft 230. Since the support shaft 230 is fixed to the second shaft hole 1222, a static sealing method can be used between the support shaft 230 and the second shaft hole 1222, such as setting a sealing ring or applying sealant.

[0058] In one embodiment, the partition portion 120 is at least partially integrally formed with the housing 110; or, the partition portion 120 and the housing 110 are separately formed, and the partition portion 120 and the housing 110 are sealed together; or, the partition portion 120 and the housing 110 are integrally formed.

[0059] In embodiments of this utility model, the partition portion 120 can be partially integrally formed with the housing 110, or partially separately formed with the housing 110, reducing the manufacturing difficulty of the handle assembly 100; the partition portion 120 can also be entirely separately formed with the housing 110, and then sealed and assembled on the housing 110, reducing the manufacturing difficulty of the handle assembly 100; the partition portion 120 can also be integrally formed with the housing 110, reducing the number of parts in the handle assembly 100 and simplifying the assembly process.

[0060] In one embodiment, the partition portion 120 includes:

[0061] The first part 121 is used to construct part of the groove wall of the assembly groove 102, and the first part 121 and the shell 110 surround to form an assembly opening 12101, which is connected to the sealing cavity 101 and the assembly groove 102 respectively.

[0062] The second part 122 is used to construct part of the groove wall of the assembly groove 102. The second part 122 is separately formed from the housing 110, and the second part 122 is sealed to the periphery of the assembly port 12101 to block the assembly port 12101. The drive assembly 200 passes through the second part 122 and is sealed to the second part 122.

[0063] Reference Figure 2 and Figure 3In an embodiment of this utility model, the partition portion 120 includes a first portion 121 and a second portion 122. The first portion 121 and the housing 110 surround and form an assembly groove 102 and an assembly port 12101 connecting the assembly groove 102 and the sealing cavity 101. The assembly port 12101 facilitates the assembly of the drive assembly 200, improving the ease of assembly of the medical handle. The second portion 122 is used to block and seal the assembly port 12101. Sealing can be achieved by adding a sealing sheet or applying sealant between the inner wall of the assembly port 12101 and the second portion 122, thereby ensuring the sealing effect of the sealing cavity 101. Specifically, in this embodiment, the first portion 121 includes a side wall plate 1211 and a top wall plate 1212. The side wall plate 1211 is integrally formed with the housing 110, while the top wall plate 1212 is separately disposed from the side wall plate 1211. During assembly, the drive assembly 200 and the second part 122 can be assembled into a whole first, then the second part 122 can be installed at the corresponding position of the assembly port 12101, and finally the top wall panel 1212 can be fastened to connect the second part 122 and the side wall panel 1211; or, the top wall panel 1212 can be connected to the side wall panel 1211 first, then the whole assembly of the drive assembly 200 and the second part 122 can be installed at the assembly port 12101, and finally the second part 122 and the top wall panel 1212 can be connected.

[0064] In one embodiment, the housing 110 is provided with a mounting groove, and the second portion 122 is inserted into the mounting groove and sealed to the inner wall of the mounting groove; and / or,

[0065] The partition 120 also includes a positioning structure, which includes a positioning protrusion 1223 and a positioning groove. One of the first part 121 and the second part 122 is provided with a positioning groove, and the other corresponding positioning groove in the first part 121 and the second part 122 is provided with a positioning protrusion 1223. The positioning protrusion 1223 cooperates with the positioning groove to position the second part 122.

[0066] In an embodiment of this utility model, the housing 110 is provided with a mounting groove, and the second part 122 is inserted into the mounting groove. The mounting groove facilitates the installation of the second part 122 itself and the sealing between the second part 122 and the housing 110. A sealing sheet or sealant can be added to the mounting groove. Specifically, in this embodiment, after the second part 122 is inserted into the mounting groove, sealant is applied around the second part 122, which seals the second part 122 and the mounting groove, as well as the second part 122 and the assembly port 12101, and makes the second part 122 more firmly fixed.

[0067] Reference Figure 7In an embodiment of this utility model, a positioning structure is provided between the first part 121 and the second part 122. The positioning structure includes a positioning protrusion 1223 and a positioning groove. The positioning groove can be provided on the first part 121, and the positioning protrusion 1223 can be correspondingly provided on the second part 122; alternatively, the positioning groove can be provided on the second part 122, and the positioning protrusion 1223 can be correspondingly provided on the first part 121. By positioning the second part 122 using a separate positioning structure, only the machining accuracy of the positioning protrusion 1223 and the positioning groove needs to be controlled. This ensures the positional accuracy of the first shaft hole 1221 and the second shaft hole 1222 on the second part 122, while avoiding increased machining difficulty and cost to control the overall accuracy of the second part 122 and the first part 121.

[0068] In one embodiment, the housing 110 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 and the second sub-housing 112 are sealed together and together form a sealed cavity 101. An assembly groove 102 and an assembly port 12101 are provided in the first sub-housing 111. The partition portion 120 is sealed together with the first sub-housing 111.

[0069] Reference Figure 1 In this embodiment of the invention, the housing 110 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 and the second sub-housing 112 are joined together to form a sealed cavity 101, reducing the processing difficulty of the housing 110 and the assembly difficulty of the components within the sealed cavity 101. The first sub-housing 111 and the second sub-housing 112 can be sealed by using a sealing sheet or applying sealant, further improving the waterproof performance of the medical handle and extending its service life.

[0070] In one embodiment, the inner edge of the groove of the assembly groove 102 is provided with a protective part 113 extending into the assembly groove 102, and the protective part 113 is provided with a drain hole 103 communicating with the inside of the assembly groove 102 and the outside of the housing 110.

[0071] Combination Figure 4 and Figure 9In this embodiment of the invention, since both the transmission gear 250 and the drive gear 240 are located in the exposed assembly groove 102, and only the transmission gear 250 engages with the biopsy needle outside the assembly groove 102, a protective part 113 is provided on the inner edge of the groove opening of the assembly groove 102. The protective part 113 covers the drive gear 240 and the rotating shaft 210, thus protecting the drive gear 240 and the rotating shaft 210, reducing the possibility of damage to the drive gear 240 and the rotating shaft 210, and reducing the possibility of liquids, dust, etc. from the external environment entering the first subspace 1021, thereby extending the service life of the medical handle. The handle assembly 100 is also provided with a drain hole 103, so that even if liquids from the external environment enter the assembly groove 102, they can flow out to the external environment through the drain hole 103, avoiding the problem of liquids not being able to drain from the assembly groove 102.

[0072] In one embodiment, the protective part 113 divides the assembly slot 102 to form a first subspace 1021 and a second subspace 1022 that are connected. The power output component 201 is disposed in the first subspace 1021 and partially extends into the second subspace 1022. The second subspace 1022 is connected to the external environment. The drain hole 103 is connected to the first subspace 1021 and the second subspace 1022.

[0073] Reference Figure 9 In this embodiment of the invention, the protective part 113 divides the assembly groove 102 into a first subspace 1021 and a second subspace 1022. The drive gear 240 and the rotating shaft 210 are both located within the first subspace 1021, and the transmission gear 250 partially extends into the second subspace 1022. The second subspace 1022 is used for the insertion of the power input component of the biopsy needle, allowing the transmission gear 250 and the power input component to engage within the second subspace 1022. This ensures a tight connection between the medical handle and the biopsy needle, resulting in a more compact biopsy sampling device structure. The drain hole 103 connects the first subspace 1021 and the second subspace 1022. Even if liquid from the external environment enters the first subspace 1021, it can flow through the drain hole 103 into the second subspace 1022 and then into the external environment, preventing the problem of liquid being unable to drain from the first subspace 1021.

[0074] Reference Figure 9 In this embodiment of the present invention, the drain hole 103 is located at the connection between the inner edge of the groove of the assembly groove 102 and the protective part 113. When the first sub-shell 111 of the medical handle is placed on the table below, the drain hole 103 is located at the lowest point of the first sub-space 1021, and the drain hole 103 is inclined, with the end communicating with the first sub-space 1021 being higher than the end communicating with the second sub-space 1022, making it easier and more convenient to drain the liquid in the first sub-space 1021.

[0075] In one embodiment, the medical handle further includes a cable assembly 310 and a second seal 320.
