Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to ultra-fine side-rotation biopsy forceps. Background Technology

[0002] Currently, biopsy forceps are essential tools for obtaining human tissue samples for pathological analysis. During biopsy, doctors use an endoscope to penetrate the body, precisely locate suspicious lesions from the acquired images, and then use the forceps to grasp the suspicious tissue for subsequent pathological biopsy and cytological examination. However, existing biopsy forceps have several shortcomings: most current biopsy forceps use a design with two forceps heads connected to two connecting plates at the tail end, forming a four-bar linkage. The opening and closing of the forceps head is controlled by the movement of this four-bar linkage. This design involves numerous parts in the assembly process, greatly increasing assembly complexity and production costs. Furthermore, existing biopsy forceps cannot effectively grasp tissues in difficult-to-access locations or angles within the human body, thus affecting the accuracy and effectiveness of diagnosis and treatment.

The first forceps head and the second forceps head are rotatably connected. The first forceps head is connected to one side of the forceps body. The forceps body is connected to the handle. One end of the traction wire passes through the second forceps head and the forceps body in sequence and extends into the handle. A push block is slidably provided on the handle. The traction wire is connected to the push block.

[0004] In another preferred embodiment, the clamp body includes a support frame and a sheath, the first clamp head being welded to one side of the support frame, and the other side of the support frame being connected to the sheath.

[0005] In another preferred embodiment, the handle includes: a fixing block, a pull rod, a lock head, and a gripping part. The fixing block connects the sheath and the gripping part. The upper end of the gripping part has a sliding groove. The push block is slidably disposed in the sliding groove. One end of the pull rod passes through the fixing block and the push block and extends into the gripping part. The other end of the pull rod extends into the sheath. One end of the traction wire is connected to the pull rod. The lock head is disposed on the push block and abuts against the pull rod.

[0006] In another preferred embodiment, the push block has a threaded hole, and one end of the lock head has an external thread that mates with the threaded hole. One end of the lock head extends into the threaded hole and abuts against the pull rod.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0020] like Figures 1-4 As shown, a preferred embodiment of an ultrafine side-turn biopsy forceps is illustrated, comprising: a first forceps head 1, a second forceps head 2, a traction wire 3, a forceps body, and a handle. The first forceps head 1 and the second forceps head 2 are rotatably connected. The first forceps head 1 is connected to one side of the forceps body, and the forceps body is connected to the handle. One end of the traction wire 3 passes through the second forceps head 2 and the forceps body in sequence and extends into the handle. A pusher block 10 is slidably provided on the handle, and the traction wire 3 is connected to the pusher block 10.

[0021] Furthermore, in a preferred embodiment, the clamp body includes a support frame 4 and a sheath 5. The first clamp head 1 is welded to one side of the support frame 4, and the other side of the support frame 4 is connected to the sheath 5, with the other side of the support frame 4 extending into the sheath 5. Furthermore, the sheath 5 provides an internal channel for the traction wire 3 and the pull rod 7, thereby providing protection and guidance.

[0022] Furthermore, as a preferred embodiment, the other side of the support frame 4 has a chamfer, which extends into the sheath 5 and connects to the sheath 5.

[0023] Furthermore, as a preferred embodiment, the sheath 5 is lightweight and soft, which helps protect the sampling forceps from bending and deformation during transportation and ordinary impacts.

[0024] Furthermore, as a preferred embodiment, the surface of the sheath 5 is relatively smooth, so that the frictional resistance between the sheath 5 and the endoscope is small when the endoscope is inserted, which facilitates the insertion of the endoscope and can also avoid scratching the endoscope forceps channel, ensuring that the sampling forceps can reach the sampling position smoothly.

[0025] Furthermore, in a preferred embodiment, the handle includes: a fixing block 6, a pull rod 7, a locking head 8, and a gripping part 9. The gripping part 9 is easy to grip. The fixing block 6 connects the sheath 5 and the gripping part 9. A groove is provided at the upper end of the gripping part 9. The push block 10 is slidably disposed in the groove. One end of the pull rod 7 passes through the fixing block 6 and the push block 10 and extends into the gripping part 9. The other end of the pull rod 7 extends into the sheath 5. One end of the traction wire 3 is connected to the pull rod 7. The locking head 8 is disposed on the push block 10 and abuts against the pull rod 7.

[0026] Furthermore, in a preferred embodiment, the push block 10 has a threaded hole, and one end of the locking head 8 has an external thread that mates with the threaded hole. One end of the locking head 8 extends into the threaded hole and abuts against the pull rod 7. Furthermore, by turning the locking head 8, the position of the pull rod 7 on the push block 10 can be locked, so that when gripping tissue, sliding the push block 10 can drive the pull rod 7 to move synchronously, thus preventing relative sliding between the push block 10 and the pull rod 7. When cleaning or maintenance of the pull rod 7 or the push block 10 is required, simply turning the locking head 8 can separate the pull rod 7 from the push block 10, facilitating disassembly and assembly.

[0027] Furthermore, as a preferred embodiment, the first pliers head 1 has a first connecting hole, and the second pliers head 2 has a second connecting hole that is directly opposite to the first connecting hole. A rivet 11 is provided in the first connecting hole and the second connecting hole, and the second pliers head 2 is rotatably connected to the first pliers head 1 through the rivet 11.

[0028] Furthermore, as a preferred embodiment, the second clamp head 2 is provided with a traction hole, and one end of the traction wire 3 passes through the traction hole.

[0029] Furthermore, in a preferred embodiment, the other end of the traction wire 3 is bent, and the other end of the traction wire 3 is connected to the second clamp head 2.

[0030] The working principle of this utility model is as follows: Before use, the sampling forceps are first strictly disinfected. When sampling is required, medical staff can push the push block 10 on the handle. The push block 10 can slide smoothly in the groove opened at the upper end of the grip 9. The sliding of the push block 10 will drive the pull rod 7 to move. When the pull rod 7 moves, it will pull the traction wire 3, which will drive the second clamp head 2 to rotate around the rivet 11, so that the first clamp head 1 and the second clamp head 2 gradually close, realizing the action of grasping tissue. The force provided by the traction wire 3 allows the doctor to grasp tissue more accurately and easily, avoiding incomplete grasping or tissue tearing due to improper force. If it is necessary to adjust the angle of the clamp head for side rotation sampling, the medical staff can adjust the direction of the grip 9 according to the actual situation while pushing the push block 10, so as to accurately grasp the target tissue from different angles.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
