[0002] The cervix is ​​prone to infection by various bacteria, making it a common site for gynecological diseases. In the screening and treatment of cervical diseases, cervical biopsy tissue sampling and examination play an important role. Cervical biopsy forceps are widely used in clinical practice due to their advantages of large sample volume and minimal harm to patients.

[0003] The existing cervical biopsy forceps have a single integrated handle and jaw. To avoid cross-infection between different patients, the forceps must either undergo a complex sterilization process after each use or be for single-use only. Reusing the forceps poses a risk of hospital-acquired infections due to their complex structure and difficulty in thorough sterilization; using them for single-use is costly and wasteful of resources.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many other different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0035] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] This invention provides a detachable biopsy sampling forceps to solve the problem that existing biopsy sampling forceps cannot balance hygiene and cost.

[0038] In the embodiments of the present invention, please refer to the references. Figures 1 to 2 The detachable biopsy sampling forceps includes a clamp assembly 10, a linkage assembly 20, and a handle assembly 30. The handle assembly 30 includes a first handle 31 and a second handle 32. The clamp assembly 10 includes at least two clamps 11 and a connecting assembly 12. The clamps 11 are connected to the connecting assembly 12, and the connecting assembly 12 is detachably connected to the first handle 31. The linkage assembly 20 is disposed on the clamp assembly 10, and the second handle 32 can drive the linkage assembly 20 to move, thereby controlling the clamps 11 to open or close.

[0039] The detachable biopsy sampling forceps uses a linkage component 20 to transmit the movement of the handle assembly 30 to the clamp 11 to control the opening and closing of the clamp 11. Both the clamp 11 and the linkage component 20 are detachably connected to the first handle 31 through the connecting component 12. Thus, after sampling, the clamp assembly 10 and the linkage component 20 can be removed from the first handle 31. That is, the clamp assembly 10 and the linkage component 20 are for single use, while the handle assembly 30 is reused, which ensures hygiene and reduces waste.

[0040] In this embodiment of the invention, the clamps 11 are used to grasp biopsy samples from the cervix. Therefore, the core function of these clamps is that they can open and close to each other to remove the samples. Thus, the number of clamps 11 should be two or more, which can be set according to actual needs. However, when the number of clamps 11 increases, the connection structure between them and the connecting component 12 will inevitably increase, which not only increases the complexity of the structure but may also cause inconvenience in operation. Therefore, in practice, it is preferred to use two clamps 11. In the following descriptions of various embodiments, the number of clamps 11 will also be described as two.

[0041] In this embodiment of the invention, the first handle 31 and the second handle 32 can be hinged or separately configured. When the first handle 31 and the second handle 32 are hinged, the first handle 31 provides a connection position for the second handle 32. Therefore, there is no need for a connection between the second handle 32 and the linkage component 20. That is, the linkage component 20 can be moved simply by abutting a portion of the second handle 32 with at least a portion of the linkage component 20. The structure is simple, disassembly is more convenient, and the hinge also facilitates one-handed operation, increasing the ease of operation. Therefore, the hinge of the first handle 31 and the second handle 32 is the preferred solution in practice. As for the case where the second handle 32 and the first handle 31 are separately configured, compared to the hinged case, only a detachable connection structure needs to be added between the linkage component 20 and the second handle 32.

[0042] In one embodiment, the connecting component 12 includes a connector 121 and a fixing seat 122. A clamp 11 is disposed at one end of the connector 121. The connector 121 is fixedly connected to the fixing seat 122. The fixing seat 122 is detachably connected to the first handle 31.

[0043] In one specific embodiment, an adapter 311 is fixedly connected to one end of the first handle 31 that is connected to the fixed base 122. A limiting structure is formed on the adapter 311 and / or the fixed base 122, and the fixed base 122 and the adapter 311 are detachably connected through the limiting structure.

[0044] The advantage of setting up the mounting bracket 122 and the adapter 311 is that it can increase the modularity of the overall structure, making it easier to install and maintain.

[0045] In a more specific embodiment, please refer to the reference. Figure 6 and Figure 8 The adapter 311 includes an adapter base 3111 and a plurality of straight rods 3112 extending upward from the upper surface of the adapter base 3111. The fixing seat 122 has mounting holes 1221 that match the number and shape of the straight rods 3112, allowing the fixing seat 122 to be inserted into the straight rods 3112. The straight rods 3112 and the mounting holes 1221 constitute the aforementioned limiting structure. In this embodiment, the straight rods 3112 and the mounting holes 1221 are preferably interference-fitted, making it less likely for the adapter 311 to detach after being connected to the fixing seat 122.

[0046] In a further specific embodiment, four straight rods 3112 are provided and arranged in two rows on both sides of the adapter 311.

[0047] The advantage of this structure is that the connection between the adapter 311 and the mounting base 122 is relatively stable and they do not rotate with each other.

[0048] In a further specific embodiment, the adapter 311 also includes an adapter spring 3113, which is disposed on opposite sides of the adapter base 3111. The fixing seat 122 is provided with a slot 1222. When the fixing seat 122 moves a preset distance along the straight rod 3112, the adapter spring 3113 is engaged in the slot 1222.

[0049] The advantages of adding the adapter spring 3113 are that, on the one hand, it can strengthen the tightness of the connection between the fixing base 122 and the adapter 311, and on the other hand, when the adapter spring 3113 is inserted into the slot 1222, the impact sound made by the two surfaces hitting each other can remind the user that the assembly is in place, which facilitates the assembly operation.

[0050] Understandably, the adapter spring 3113 and slot 1222 can also be used independently when the straight rod 3112 is not present. However, this snap-fit ​​design is less stable than the combined design. Therefore, in practice, it is preferable to use the straight rod 3112 for primary fixing and the adapter spring 3113 for secondary fixing.

[0051] In one embodiment, please refer to the reference. Figure 3-5 With the connecting component 12 including the connector 121 and the fixing base 122, the linkage component 20 includes a clamp support member capable of elastic deformation and a push tube 21; the clamp support member is disposed between the clamps 11 or between the clamps 11 and the connector 121, and is used to spread the clamps 11 apart; the push tube 21 is sleeved on the outside of the connector 121 and is slidably connected to the fixing base 122, one end of the push tube 21 abuts against the second handle 32, and the second handle 32 can push the push tube 21 to move towards the clamps 11, so that the clamps 11 partially enter the front opening of the push tube 21, thereby closing the clamps 11.

[0052] In one specific embodiment, the clamp 11 is preferably a structure with an upward bulge in the middle. When the two clamps 11 are closed, the distance between the highest points of the bulges of the two clamps 11 is greater than the inner diameter of the front opening of the push tube 21, so that the clamps 11 cannot completely enter the push tube 21.

[0053] The above structure can prevent the push tube 21 from moving too far and causing injury to the patient, and can also prevent the push tube 21 from becoming disconnected from the fixed seat 122.

[0054] In one specific embodiment, please refer to Figure 4 The clamp support is configured as a clamp spring 22. The clamp 11 is hinged to the connector 121, and the hinge point separates the jaw part 111 for sampling and the movable part 112 for driving the jaw part 111 to move. The clamp spring 22 is placed between the movable part 112 and the connector 121, thereby opening the jaw part 111. When the jaw part 111 is closed by external force, the clamp spring 22 is pressed down. When the external force is removed, the clamp spring 22 pushes the movable part 112 to reset, and the jaw part 111 opens.

[0055] In a more specific embodiment, please refer to Figure 9 The connector 121 includes a cylindrical section 1211 with a circular cross-section and a prism section 1212 with a square cross-section. The prism section 1212 is used to connect two mounting plates extending forward from the end sidewall of the clamp 11. The two clamps 11 are rotatably connected to the connector 121 by shaft elements such as pins or bolts. One end of the clamp spring 22 is fixedly connected to the prism section 1212, and the other end is placed under the movable part 112.

[0056] In another specific embodiment, the clamp support can be configured as a spring supporting the two clamps 11.

[0057] In one specific embodiment, please refer to Figure 3 , Figure 6 and Figure 10 The fixing base 122 is a tubular structure with a central through hole. The push tube 21 is inserted into the central through hole for sliding connection with the fixing base 122. The push tube 21 has a relief groove 211. The fixing base 122 and the connector 121 have connection holes 1223. The fastener passes through the connection hole 1223 on the fixing base 122, passes through the relief groove 211, and connects with the connection hole 1223 on the connector 121. The aforementioned fasteners include, but are not limited to, screws, bolts, and pins.

[0058] It is understandable that the fixing seat 122 can also be configured as a non-tubular structure, as long as it has an arc-shaped surface that surrounds the push tube 21 or forms a guide structure such as a slide rail or a slide groove with the push tube 21, so that the push tube 21 and the fixing seat 122 can form a sliding connection relationship.

[0059] In a more specific embodiment, please refer to the reference. Figure 7 and Figure 9 A groove 1224 is provided on the wall of the middle through hole of the fixing base 122, and a protrusion 1213 is formed at the end of the connector 121 to cooperate with the groove 1224. The protrusion 1213 can be slid along the groove 1224 to align with the connecting hole 1223 on the fixing base 122 and the connector 121.

[0060] In a further specific embodiment, a limiting boss 1225 is formed on the inner wall of the intermediate through hole of the fixing seat 122. The limiting boss 1225 is disposed opposite to the slide groove 1224 and located in the relief groove 211, and its bottom surface abuts against the outer surface of the connector 121.

[0061] The advantage of setting the limiting boss 1225 is that, together with the slide groove 1224, it further facilitates the alignment of the connecting holes 1223 on the fixing seat 122 and the connecting member 121.

[0062] In a further specific embodiment, the connector 121 includes a main body and a connecting block. Connecting holes 1223 are provided at corresponding positions on the main body and the connecting block. A receiving hole is provided at the end of the main body. The receiving hole opens radially outward to form a clearance groove. A protrusion 1213 is formed on the connecting block. When the connecting block is inserted into the receiving hole, the protrusion 1213 slides in along the clearance groove until the connecting holes 1223 on the main body and the connecting block are aligned, thereby forming the connector 121.

[0063] In one specific embodiment, a push tube reset member 212 is provided between the push tube 21 and the fixed base 122. When an external force is applied to the second handle 32, the second handle 32 pushes the push tube 21 forward, and the push tube reset member 212 undergoes elastic deformation. When the external force is removed, the push tube reset member 212 returns to its original state, and drives the push tube 21 and the second handle 32 to reset.

[0064] In a more specific embodiment, please refer to Figure 1 , Figure 2 and Figure 6 The push tube reset component 212 is set as a spring, which is sleeved on the push tube 21. The end of the push tube 21 is fixedly connected to the limit block 213. One end of the spring 212 abuts against the fixed seat 122, and the other end abuts against the limit block 213.

[0065] In the above embodiment, the spring 212 is compressed when the push tube 21 is pushed forward. In another more specific embodiment, the spring can also be disposed on the side of the fixing base 122 facing the clamp 11, in which case the spring is stretched when the push tube 21 is pushed forward. It is understood that the spring can also be replaced by elastic elements such as rubber or elastic rope, which will not be described in detail here.

[0066] In one specific embodiment, the handle assembly 30 further includes a handle reset member 33, one end of which is connected to the first handle 31 and the other end of which is connected to the second handle 32. The handle reset member 33 can generate elastic deformation when an external force is applied to the first handle 31 and the second handle 32, and drive the first handle 31 and the second handle 32 to reset when the external force is removed.

[0067] In a more specific embodiment, please refer to Figure 1 The first handle 31 and the second handle 32 are hinged together. The handle reset component 33 is a spring, which is vertically positioned. One end of the spring is fixedly connected to the second handle 32, with the connection point located above the hinge point of the first handle 31 and the second handle 32. The other end of the spring is fixedly connected to the first handle 31, with the connection point located below the hinge point of the first handle 31 and the second handle 32. When an external force is applied to the first handle 31 and the second handle 32, causing them to move closer together, the spring is stretched. When the external force is removed, the spring retracts, causing the first handle 31 and the second handle 32 to reset.

[0068] It is understandable that the handle reset member 33 can also be set as a spring piece supported between the first handle 31 and the second handle 32. This is existing technology and will not be described in detail here.

[0069] It should be noted that in the above embodiments, the push tube 21 can also be replaced with a non-tubular element. The specific implementation scheme can be obtained by modifying the above embodiments in combination with conventional technical means, which will not be elaborated here.

[0070] In a preferred embodiment combining the foregoing embodiments, the detachable biopsy sampling forceps operates as follows: the operator applies force to the gripping area of ​​the handle assembly 30, causing the first handle 31 and the second handle 32 to move closer together. The handle reset member 33 is stretched, and the end of the second handle 32 pushes the push tube 21 towards the clamp assembly 10. The push tube reset member 212 is compressed, and the push tube 21 pushes the two clamps 11 to close together to grasp the sample. The clamp spring 22 is pressed down by the movable part 112 of the clamp 11. When the external force is removed, the handle reset member 33 retracts, pulling the handle assembly 30 back to its original position. The push tube reset member 212 springs back, pushing the push tube 21 back relative to the clamps 11. The clamp spring 22 springs back, causing the two clamps 11 to open together, thus enabling re-sampling of the same patient. After the procedure, the fixation base 122 and its connected components are removed from the adapter 311 and discarded, while the handle assembly 30 is recycled. Before the next round of sampling, remove the handle assembly 30 and connect the new clamp assembly 10 and linkage assembly 20 to the adapter 311 via the fixing base 122. Specifically, connect the adapter 311 to the straight rod 3112 of the adapter 311 through the mounting hole 1221 until the adapter spring 3113 is inserted into the slot 1222 and an audible prompt is made. At this point, the assembly is complete, and a new round of sampling can be carried out.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
