[0002] Laparoscopic instruments are tools used in laparoscopic surgery. They mainly include laparoscopic instruments and thoracic instruments, which have many functions and are diverse in type. They are important instruments commonly used in surgery.

[0003] Existing laparoscopic instruments are generally as shown in the instruction manual. Figure 1 As shown, most of them have a straight handle structure. When using them, due to differences in the body size of different patients, the different layout of the puncture cannula for different surgeries, and the different arm lengths of different doctors, using the same laparoscopic instruments may cause some doctors to operate in an ergonomic manner. For example, doctors need to maintain an extended arm position for a long time during the operation, which can easily lead to fatigue. Moreover, long-term operation in this state can also easily cause occupational diseases such as frozen shoulder, cervical spondylosis, and tenosynovitis in doctors. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a malleable laparoscopic instrument to address the issue that most existing laparoscopic instruments have a straight handle structure, which makes it inconvenient to flexibly adjust the length and orientation of the operating handle. Doctors often need to maintain an extended arm position for a long time to perform surgical operations, which is not only easy to cause fatigue, but also easy to induce occupational diseases in doctors.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A malleable laparoscopic instrument includes an instrument rod, one end of which is provided with an operating head, and the other end of the instrument rod away from the operating head is provided with a bending unit. The bending unit is connected to a main operating handle. The bending unit is a malleable flexible tube, and a transmission cable is provided inside the bending unit. The two ends of the transmission cable are respectively connected to the shafts of the operating head and the main operating handle.

[0007] A secondary operating handle is fitted onto the main operating handle. A movable main handle is rotatably mounted on the lower end of the main operating handle. A first locking mechanism for fixing the movable main handle is provided on the main operating handle.

[0008] Optionally, a rotation knob is installed on the instrument lever, and the rotation knob is located between the bending unit and the main operating handle.

[0009] Optionally, both the main operating handle and the auxiliary operating handle have grooves at their lower ends. A movable main block is fixed to the top of the movable main handle, and a movable auxiliary block is fixed to the top of the movable auxiliary handle. The movable main block is rotatably installed in the groove at the lower end of the main operating handle, and the movable auxiliary block is rotatably installed in the groove at the lower end of the auxiliary operating handle.

[0010] Optionally, the first locking mechanism includes a first fastening bolt, which is threaded into the main operating handle and abuts against the middle of the movable main block to form a fixation; the first fastening bolt is threaded into the auxiliary operating handle and abuts against the middle of the movable auxiliary block to form a fixation.

[0011] Optionally, a limiting ear is provided on the side of the movable main handle facing the movable secondary handle, and a limiting block is fixed on the side of the movable secondary handle facing the movable main handle, and the limiting block is located between the limiting ears, with the limiting ears limiting the limiting block in a horizontal direction.

[0012] Optionally, the lower end of the movable main handle is fixed with an extension main rod, and the top end of the extension main handle is sleeved and installed on the lower end of the extension main rod to form a telescopic structure.

[0013] Optionally, the lower end of the movable secondary handle is fixed with an extension secondary rod, and the top end of the extension secondary handle is sleeved and installed on the lower end of the extension secondary rod to form a telescopic mechanism.

[0014] Optionally, the second locking mechanism includes a second fastening bolt, which is threaded into the extension main shank and abuts against the extension main rod, and a second fastening bolt is threaded into the extension secondary shank and abuts against the extension secondary rod.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, the orientation can be adjusted to a certain extent by setting a bending unit, and the operating direction can be further adjusted by the movable main handle and the movable secondary handle. At the same time, with the extension main handle and the extension secondary handle, the operating length of the main operating handle and the secondary operating handle can be adjusted as needed. With the help of two locking mechanisms, the structural strength of the instrument can be maintained while achieving flexible shaping at various angles.

[0017] Meanwhile, the length of the main and auxiliary operating handles can be freely adjusted according to the different hand lengths of different doctors to further improve the comfort of doctors when holding the device and help alleviate the fatigue of doctors during long surgical operations.

[0018] In summary, this device can effectively improve the operating comfort of surgeons, reduce work fatigue, thereby improving surgical efficiency and safety, and reducing the incidence of occupational diseases such as frozen shoulder, cervical spondylosis, and tenosynovitis among surgeons.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0029] The present invention provides a malleable endoscopic instrument in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0030] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0031] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0032] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0033] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0034] like Figures 2 to 6As shown, an embodiment of this utility model provides a malleable endoscopic instrument, including an instrument rod 1. One end of the instrument rod 1 is provided with an operating head 2, which can be a clamp, a gripper, or scissors, and is not specifically limited. The other end of the instrument rod 1 is provided with a main operating handle 3 and a secondary operating handle 4 for operating the operating head 2.

[0035] The end of the instrument rod 1 furthest from the operating head 2 is provided with a bending unit 102, which is connected to the main operating handle 3, specifically as follows: Figure 4 As shown, the bending unit 102 is a flexible hose covered with a soft rubber layer, allowing it to be bent in any direction. In practice, the bending unit 102 can be 20cm-30cm in length, depending on actual needs. A transmission cable 103 is installed inside the bending unit 102. The two ends of the transmission cable 103 are connected to the shafts of the operating head 2 and the main operating handle 3, respectively. This allows the main operating handle 3 to still drive the operating head 2 to move via the transmission cable 103 when the bending unit 102 is in a bent state, thus providing control. In other embodiments, the transmission cable 103 can also be a multi-degree-of-freedom bending member or a ball-joint serpentine structure.

[0036] The instrument lever 1 is also equipped with a rotation knob 101, which is located between the bending unit 102 and the main operating handle 3. This ensures that after bending by the bending unit 102, the rotation knob 101 and the main operating handle 3 are adjacent to each other, facilitating the operation of the rotation knob 101. In practice, the rotation knob 101 is a common control knob in existing laparoscopic instruments, which can be used to adjust the angle or direction of the instrument head. By precisely adjusting the angle and direction of the instrument, the flexibility and accuracy of the surgery can be further improved.

[0037] like Figure 2 As shown, the main operating handle 3 cooperates with the auxiliary operating handle 4. A movable main handle 5 is rotatably mounted on the lower end of the main operating handle 3, and a movable auxiliary handle 7 is rotatably mounted on the lower end of the auxiliary operating handle 4. A retractable extension main handle 6 is provided at the lower end of the movable main handle 5, and a retractable extension auxiliary handle 8 is provided at the lower end of the movable auxiliary handle 7. A first locking mechanism for fixing the movable main handle 5 is provided on the main operating handle 3, a first locking mechanism for fixing the movable auxiliary handle 7 is provided on the auxiliary operating handle 4, and a second locking mechanism for fixing after extension and retraction is provided on the extension main handle 6 and the extension auxiliary handle 8, respectively.

[0038] The main operating handle 3 is extended by using the movable main handle 5 and the extended main handle 6, and the auxiliary operating handle 4 is extended by using the movable secondary handle 7 and the extended secondary handle 8. This makes the grip part of the instrument malleable, making it easy to adjust the operating angle and length. During the operation, the doctor's upper limb can be placed in a comfortable position without having to maintain an extended arm for a long time. At the same time, the two locking mechanisms can further ensure the operation effect.

[0039] like Figure 2 and Figure 5 As shown, the lower ends of the main operating handle 3 and the auxiliary operating handle 4 are both provided with grooves. The top of the movable main handle 5 is fixed with a movable main block 501, and the top of the movable auxiliary handle 7 is fixed with a movable auxiliary block 701. The movable main block 501 is rotatably installed in the groove at the lower end of the main operating handle 3, and the movable auxiliary block 701 is rotatably installed in the groove at the lower end of the auxiliary operating handle 4, so that the movable main handle 5 and the movable auxiliary handle 7 can rotate relative to the instrument rod 1.

[0040] like Figure 6 As shown, the first locking mechanism includes a first fastening bolt 9. The first fastening bolt 9, which is installed on the main operating handle 3, is threaded into the main operating handle 3 and abuts against the middle of the movable main block 501 to form a fixation. The first fastening bolt 9, which is installed on the auxiliary operating handle 4, is threaded into the auxiliary operating handle 4 and abuts against the middle of the movable auxiliary block 701 to form a fixation.

[0041] Two limiting ears 502 are provided on the side of the movable main handle 5 facing the movable secondary handle 7. A limiting block 702 is fixed on the side of the movable secondary handle 7 facing the movable main handle 5. The two limiting ears 502 are symmetrically arranged, and the limiting block 702 is located between the two limiting ears 502. The limiting ears 502 limit the limiting block 702 in the horizontal direction to keep the rotation angle of the movable main handle 5 and the movable secondary handle 7 consistent.

[0042] The lower end of the movable main handle 5 is fixed with an extension main rod 503, and the top end of the extension main handle 6 is sleeved and installed on the lower end of the extension main rod 503 to form a telescopic structure; the lower end of the movable secondary handle 7 is fixed with an extension secondary rod 703, and the top end of the extension secondary handle 8 is sleeved and installed on the lower end of the extension secondary rod 703 to form a telescopic mechanism.

[0043] The second locking mechanism includes a second fastening bolt 10, which is threaded into the extension main handle 6 and abuts against the extension main rod 503. The second fastening bolt 10 is threaded into the extension secondary handle 8 and abuts against the extension secondary rod 703.

[0044] The workflow of the technical solution provided by this utility model is as follows:

[0045] In use, the bending unit 102 allows for a certain degree of directional adjustment, and the operating direction is further adjusted by rotating the movable main handle 5 and the movable secondary handle 7. Simultaneously, the extension main handle 6 and the extension secondary handle 8, in conjunction with these mechanisms, allow for adjustment of the operating lengths of the main operating handle 3 and the secondary operating handle 4 as needed. Furthermore, two locking mechanisms ensure flexible shaping at various angles while maintaining the structural strength of the instrument.

[0046] In summary, this device can effectively improve the operating comfort of surgeons, reduce work fatigue, thereby improving surgical efficiency and safety, and reducing the incidence of occupational diseases such as frozen shoulder, cervical spondylosis, and tenosynovitis among surgeons.

[0047] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0048] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
