Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a gynecological grasping forceps. Background Technology

[0002] In the diagnosis and treatment of gynecological diseases, biopsy forceps are a crucial medical instrument widely used to obtain tissue samples for pathological examination. This allows for pathological analysis, accurately determining whether a patient has lesions and the severity of those lesions.

[0003] Related prior art, such as Chinese patent application "A Cervical Biopsy Forceps for Obstetrics and Gynecology", application number: CN202311466392.6, discloses a forceps body including a fixed handle, a movable handle, a fixed tube, a connecting rod, and a biopsy forceps body. One end of the fixed tube is connected to the top of the fixed handle, and the other end is connected to the biopsy forceps body. The connecting rod passes through the fixed handle and the fixed tube, with one end connected to the biopsy forceps body and the other end connected to the movable handle. The biopsy forceps body includes a forceps body, an upper forceps head, a lower forceps head, and a connecting mechanism. The forceps body and the upper forceps head are connected as a whole. The upper forceps head is movably connected to the forceps body through the connecting mechanism. By pulling the connecting rod through the movable handle, the upper forceps head is moved up and down and closed within the forceps body. When the upper and lower forceps heads are closed, the head is in the shape of a smooth sphere.

[0004] For example, Chinese patent application "A Novel Gynecological Biopsy Forceps", application number: CN202120358380.1, discloses a forceps bar portion, a clamping portion with a front end of the forceps bar portion, and a handle portion with a rear end of the forceps bar portion; the forceps bar portion includes an upper forceps bar and a lower forceps bar; the upper forceps bar has an upper sliding rod that is slidably engaged inside, and the lower forceps bar has a lower sliding rod that is slidably engaged inside; the clamping portion includes an upper clamp and a lower clamp; the handle portion includes a front handle and a rear handle; the upper rear ends of the front handle and the rear handle are hinged together; the hinged handle portion controls the upper sliding rod to slide within the upper forceps bar through a second rotating connector, and the upper sliding rod, in turn, controls the upper clamp and the lower clamp to engage through the first rotating connector at the front end for excision and sampling.

[0005] However, the aforementioned existing technologies still have certain limitations. Some biopsy forceps have complex structural designs with numerous components, which not only increases production costs but also poses significant challenges to product manufacturing and assembly, making them difficult to adapt to the efficient modes of modern automated production. For example, the complex connection structure and numerous components require more manpower and time for assembly and debugging, reducing production efficiency. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a gynecological grasping forceps that, by optimizing the product structure and reducing unnecessary parts, further reduces the cost of the product and alleviates the burden of medical costs.

[0007] The technical solution adopted in this application is as follows: a gynecological grasping forceps, including a clamping assembly, a fixed handle and a movable handle. The fixed handle includes a rod, a handle and a connecting part. The rod and the handle are connected by the connecting part. The included angle between the rod and the handle is an acute angle or a right angle. The top of the connecting part is provided with an installation slot, and the rear end of the connecting part is provided with an insertion port. The tail end of the clamping assembly is inserted into the installation slot through the rod. The top of the movable handle passes through the insertion port through the connecting part to the installation slot and is hinged to the clamping assembly. The movable handle and the fixed handle are connected by a pivot, which is located at the connecting part.

[0008] Compared with the prior art, the advantages of this application are as follows: First, by rationally designing the structure of the fixed handle, the tail end of the clamp assembly is inserted into the mounting slot of the fixed handle rod, and the top of the movable handle passes through the insertion port and is hinged to the clamp assembly at the mounting slot. The overall number of parts is relatively reduced, which reduces production costs. At the same time, it simplifies the manufacturing and assembly process, and can better adapt to the efficient mode of modern automated production, thereby improving production efficiency.

[0009] Secondly, the rod and handle form an acute or right angle through the connection. This structural design helps to provide more suitable mechanical support and operating angle during use. When grasping tissue samples, it can make the force more effectively transmitted to the clamp assembly, improve the stability and reliability of the grasp, and at the same time help doctors operate more accurately and reduce errors caused by inconvenient operation.

[0010] In this application, for ease of description, the end where the biopsy forceps assembly is located is referred to as the front, and the end away from the end where the forceps assembly is located is referred to as the back.

[0011] In some embodiments of this application, the mounting slot extends through the top and rear ends of the connector, and the insertion port is located below the mounting slot. This layout facilitates the insertion of the tail end of the clamp assembly into the mounting slot via the rod, while the top of the movable handle can pass through the connector from the insertion port below to the mounting slot and hinge with the clamp assembly, further simplifying the assembly process and improving the convenience and efficiency of assembly.

[0012] In some embodiments of this application, a side cover is provided at the mounting slot, a slide rail is provided on the bottom surface of the mounting slot in the horizontal direction, the longitudinal section of the slide rail is an inverted L-shaped structure, and a bayonet is provided at the tail end of the slide rail.

[0013] The inner wall surface of the side cover is provided with a sliding groove to adapt to the slide rail, and the tail end of the sliding groove is provided with a locking protrusion corresponding to the locking slot; the side cover moves along the slide rail until the locking protrusion is engaged with the locking slot.

[0014] By setting up a side cover and a snap-fit ​​structure, the mounting slot is sealed after assembly, effectively protecting the connection structure between the internal clamping components and the movable handle, preventing foreign objects from entering or the external environment from affecting the connection structure, and improving the reliability and service life of the gripper.

[0015] In some embodiments of this application, the bottom of the movable handle is integrally circular for the user's thumb to pass through. This circular design is ergonomic, providing a more comfortable grip and allowing the user to apply force more stably when operating the gripper, reducing hand fatigue and improving operational flexibility and precision.

[0016] In some embodiments of this application, the bottom of the fixed handle has an oblong hole for the user's four fingers to pass through. The oblong hole is also designed based on ergonomic principles, making it convenient for the user's four fingers to pass through and grip the fixed handle, enhancing the fit between the gripper and the hand, providing a more stable grip, which helps to maintain the stability of the gripper during operation, and improves the accuracy and safety of the operation.

[0017] In some embodiments of this application, the rod is a tubular structure, and its inner wall structure is adapted to the clamp assembly. A limiting ring is provided at the tail end of the inner wall of the rod. The clamp assembly is installed in place when it is inserted into contact with the limiting ring. The tubular rod structure is simple and strong, and its inner wall surface is adapted to the clamp assembly, ensuring smooth and unobstructed insertion of the clamp assembly. The limiting ring provides a clear limit for the clamp assembly to be installed in place, preventing over-insertion or under-insertion, and ensuring the overall assembly quality and performance of the gripper.

[0018] In some embodiments of this application, the front end of the rod is provided with multiple grippers, which together form an annular structure with external threads on its outer surface. A gap exists between adjacent grippers. The rod is equipped with a locking nut, which has internal threads and is threadedly connected to the multiple grippers. Rotating the locking nut adjusts the gap between the grippers. This design allows the inner diameter of the annular structure formed by the multiple grippers to be adjusted as needed, facilitating adaptation and disassembly between different specifications of clamp assemblies or connecting parts. This increases the versatility and flexibility of the gripper, and also facilitates the replacement or maintenance of the clamp assembly.

[0019] In addition, this application can also design a corresponding snap-fit ​​structure on the inner wall of the rod so that the sleeve is snapped in place after installation, thereby preventing the sleeve from falling off.

[0020] In some embodiments of this application, the clamp assembly includes a sleeve and a pull rod. The tail end of the sleeve is inserted into the rod, and a first clamping head is movably mounted on the front end of the sleeve. The tail end of the pull rod passes through the sleeve and is hinged to the top of the movable handle. This split-type clamp assembly design simplifies the internal structure and facilitates production and assembly. The cooperation between the sleeve and the pull rod ensures that the pull rod slides stably within the sleeve, thereby realizing the opening and closing action of the first clamping head. The structure is compact and reliable, improving the working efficiency and stability of the gripping clamp.

[0021] In some embodiments of this application, the top surface of the movable handle has an insertion slot, the tail end of the pull rod is inserted into the insertion slot, and a pin passes through the tail end of the pull rod and the wall of the insertion slot; the first jaw and the second jaw are rotatably connected, and the front end of the pull rod is hinged to the second jaw. The fixing method of the insertion slot and the pin makes the connection between the pull rod and the movable handle more stable, preventing the pull rod from loosening or falling off during operation. The rotatable connection between the first jaw and the second jaw, and the hinge of the pull rod to the second jaw, enable the jaws to rotate flexibly around the axis under the drive of the pull rod, realizing accurate and stable opening and closing actions, effectively improving the accuracy and success rate of grasping tissues.

[0022] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0026] The present application will now be described in detail with reference to the accompanying drawings.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0028] A gynecological grasping forceps, as described in Example 1 Figures 1 to 2 As shown: It includes a clamp assembly 1, a fixed handle 2 and a movable handle 8. The fixed handle 2 includes a rod 3, a handle 4 and a connecting part 5. The rod 3 and the handle 4 are connected by the connecting part 5. The included angle between the rod 3 and the handle 4 is an acute angle or a right angle. This structural design helps to provide more suitable mechanical support and operating angle during use. When grasping tissue samples, it can make the force more effectively transmitted to the clamp assembly 1, improve the stability and reliability of grasping, and also help doctors operate more accurately and reduce errors caused by inconvenient operation.

[0029] The top of the connecting part 5 has a mounting slot 6, and the rear end of the connecting part 5 has an insertion port 7. The tail end of the clamp assembly 1 is inserted into the mounting slot 6 via the rod part 3. The top of the movable handle 8 passes through the insertion port 7 through the connecting part 5 to the mounting slot 6 and is hinged to the clamp assembly 1. The movable handle 8 and the fixed handle 2 are connected by a pivot 9 located at the connecting part 5. By rationally designing the structure of the fixed handle 2, inserting the tail end of the clamp assembly 1 into the mounting slot 6 of the rod part 3 of the fixed handle 2, and the top of the movable handle 8 passing through the insertion port 7 and hinged to the clamp assembly 1 at the mounting slot 6, the overall number of parts is relatively reduced, lowering production costs. It also simplifies manufacturing and assembly processes, better adapts to the efficient mode of modern automated production, and improves production efficiency.

[0030] In this application, for ease of description, the end where the biopsy forceps assembly 1 is located is referred to as the front, and the end away from the end where the forceps assembly 1 is located is referred to as the rear.

[0031] Example 2, as Figures 1 to 3As shown, the mounting slot 6 extends through the top and rear ends of the connecting part 5, and the insertion port 7 is located below the mounting slot 6. This layout facilitates the insertion of the tail end of the clamp assembly 1 into the mounting slot 6 via the rod part 3, while the top of the movable handle 8 can pass through the connecting part 5 from the insertion port 7 below to the mounting slot 6 and hinge with the clamp assembly 1, further simplifying the assembly process and improving the convenience and efficiency of assembly.

[0032] A side cover 10 is provided at the mounting slot 6. A slide rail 11 is provided horizontally on the bottom surface of the mounting slot 6. The longitudinal section of the slide rail 11 is an inverted L-shaped structure, and a latch 12 is provided at the tail end of the slide rail 11. The inner wall surface of the side cover 10 is provided with a sliding groove 13 to adapt to the slide rail 11. The tail end of the sliding groove 13 is provided with a latching protrusion 14 corresponding to the latch 12. The side cover 10 moves along the slide rail 11 until the latching protrusion 14 is engaged with the latch 12. By setting the side cover 10 and the latching structure, the mounting slot 6 is sealed after assembly, effectively protecting the connection structure between the internal clamp assembly 1 and the movable handle 8, preventing foreign objects from entering or the external environment from affecting the connection structure, and improving the reliability and service life of the gripper.

[0033] The bottom of the movable handle 8 is circular, allowing the user's thumb to pass through.

[0034] The bottom of the fixed handle 2 has an oblong hole 15 for the user's four fingers to pass through. The oblong hole 15 is also designed based on ergonomic principles, making it convenient for the user's four fingers to pass through and grip the fixed handle 2, enhancing the fit between the gripper and the hand, providing a more stable grip, which helps to maintain the stability of the gripper during operation, and improves the accuracy and safety of operation.

[0035] The rod 3 has a tubular structure, and its inner wall structure is adapted to the clamp assembly 1. A limiting ring 16 is provided at the tail end of the inner wall of the rod 3. The clamp assembly 1 is installed in place when it is inserted into contact with the limiting ring 16. The tubular rod 3 has a simple and high-strength structure. Its inner wall surface is adapted to the clamp assembly 1, which can ensure that the clamp assembly 1 is inserted smoothly and without obstruction. The limiting ring 16 provides a clear limit for the clamp assembly 1 to be installed in place, preventing the clamp assembly 1 from being over-inserted or under-installed, thus ensuring the overall assembly quality and performance of the gripper.

[0036] The clamp assembly 1 includes a sleeve 19 and a pull rod 20. The tail end of the sleeve 19 is inserted into the rod, and the front end of the sleeve 19 is movably mounted with a first clamp head 21. The tail end of the pull rod 20 passes through the sleeve 19 and is hinged to the top of the movable handle 8. This split-type clamp assembly 1 design simplifies the internal structure and facilitates production and assembly. The cooperation between the sleeve 19 and the pull rod 20 ensures that the pull rod 20 slides stably within the sleeve 19, thereby realizing the opening and closing action of the first clamp head 21. The structure is compact and reliable, improving the working efficiency and stability of the gripper.

[0037] The top surface of the movable handle 8 has an insertion slot 22. The tail end of the pull rod 20 is inserted into the insertion slot 22, and the pin 23 passes through the tail end of the pull rod 20 and the wall of the insertion slot 22. The first jaw 21 and the second jaw 24 are rotatably connected, and the front end of the pull rod 20 is hinged to the second jaw 24. The fixing method of the insertion slot 22 and the pin 23 makes the connection between the pull rod 20 and the movable handle 8 more stable, preventing the pull rod 20 from loosening or falling off during operation. The rotatable connection between the first jaw 21 and the second jaw 24 and the hinge of the pull rod 20 to the second jaw 24 enable the jaws to rotate flexibly around the axis under the drive of the pull rod 20, realizing accurate and stable opening and closing actions, effectively improving the accuracy and success rate of grasping tissues.

[0038] The rest of the contents of Example 2 are the same as those of Example 1.

[0039] Example 3, as Figures 3 to 4 As shown, the other contents of Embodiment 3 are the same as those of Embodiment 2, except that the rod 3 of the fixed handle 2 has been further improved. The front end of the rod 3 is provided with multiple grippers 17, which form a ring-shaped structure with external threads on its outer surface. There is a gap between adjacent grippers 17. The rod 3 is equipped with a locking nut 18, which has internal threads and is threadedly connected to the multiple grippers 17. Rotating the locking nut 18 can adjust the gap between the grippers 17. This design allows the inner diameter of the ring-shaped structure formed by the multiple grippers 17 to be adjusted as needed, facilitating adaptation and disassembly between different specifications of clamp assemblies 1 or connecting parts 5, increasing the versatility and flexibility of the gripper, and also facilitating the replacement or maintenance of the clamp assembly 1. Furthermore, this application can also design a corresponding snap-fit ​​structure on the inner wall of the rod 3, so that the sleeve 19 is locked in place after installation, thereby preventing the sleeve 19 from falling off.
