Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endoscope-assisted needle control and suture-cutting device. Background Technology

[0002] Minimally invasive surgery is a type of surgery with tiny incisions. Because of the small incision, it can reduce blood loss during the procedure and decrease postoperative pain. Specifically, during a minimally invasive surgery, the surgeon places an endoscope inside the patient's body to observe the internal environment. The endoscope facilitates the surgeon's ability to perform surgical procedures and perform postoperative suturing.

[0003] In minimally invasive surgery, there is a widespread need for devices that can close wounds with sutures, similar to those used in open abdominal surgery. Many existing techniques cannot perform continuous suturing of the wound in a single procedure, requiring multiple installations of the suture device. Even among devices capable of continuous suturing in a single procedure, the control of fixing and releasing the auxiliary needle is not very smooth or reliable. Furthermore, the cutting and disposal of the sutures after suturing is cumbersome and requires improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a device with a reasonable structure and convenient operation for the operator, addressing the shortcomings of the aforementioned background technology.

[0005] To achieve the above objectives, the present invention provides an endoscope-assisted needle control and suture-pulling device, including an auxiliary needle control module and a suture-pulling module.

[0006] The auxiliary needle control module includes a locking seat, a locking device disposed in the locking seat, and a first control component connected to the locking device. The locking device matches the auxiliary needle and can fix or release the auxiliary needle.

[0007] The suture cutting module includes a suture cutting seat, a suture anchor, and a second control component connected to the suture anchor. The first end of the suture anchor is provided with a spike to anchor into human tissue. The suture cutting seat is provided with a suture cutting part for cutting the suture.

[0008] Furthermore, the auxiliary pin is provided with a slot, the engaging device is made of elastic material, and the first end of the engaging device is provided with a locking block that matches the slot.

[0009] Furthermore, the second end of the engaging device is provided with a control surface, which is inclined relative to the axial direction of the engaging device. A control ball is provided at the position of the control surface, and the control ball is connected to the first control component through a first control wire.

[0010] Furthermore, the first control component includes a first control base and a control button, the control button is movably connected to the first control base, the first control wire is connected to the control button, and a first return spring is also provided between the control button and the first control base.

[0011] Furthermore, the auxiliary needle control module also includes a first connecting rod, the two ends of which are respectively connected to the first control seat and the locking seat, and the first control wire passes through the inside of the first connecting rod.

[0012] Furthermore, the lifting anchor is spirally arranged.

[0013] Furthermore, the second control component includes a second control seat and a control knob, the control knob being movably connected to the second control seat, the control knob being connected to the lifting anchor via a second control steel wire, and a second return spring being provided between the control knob and the second control seat.

[0014] Furthermore, the lifting and wire-cutting module also includes a second connecting rod, the two ends of which are respectively connected to the second control seat and the lifting and wire-cutting seat, and the second control wire passes through the inside of the second connecting rod.

[0015] Furthermore, the cutting part is a blade, the blade is arranged in a ring shape, and the blade is integrally formed with the edge of the lifting cutting seat.

[0016] Furthermore, it also includes an operating console, to which both the first control component and the second control component are connected.

[0017] The above-described solution of the present invention has the following beneficial effects:

[0018] The endoscopic auxiliary needle control and suture-cutting device provided by this invention, through the combination of an auxiliary needle control module and a suture-cutting module, can conveniently control the fixing and loosening of the auxiliary needle, the lifting of human tissue, and the final cutting of the suture. The structure is reasonable and the operation is convenient. In particular, the suture-cutting module has the functions of lifting human tissue and cutting suture at the same time. Compared with the setting of two modules, it can reduce the occupation of the valuable endoscope channel, save the module installation steps, simplify the operation process, and thus improve the quality of surgery.

[0019] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0029] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] like Figure 1 As shown, an embodiment of the present invention provides an endoscopic auxiliary needle control and suture-cutting device, including an auxiliary needle control module and a suture-cutting module. The auxiliary needle control module controls the fixing and releasing of the auxiliary needle 1, which is connected to the suture 2. Initially, the auxiliary needle 1 is integrated with the main needle 3. During suturing, the main needle 3 and the auxiliary needle 1 are inserted through a hole on the first side of the wound. Then, the auxiliary needle 1 is inserted into the auxiliary needle control module, which fixes it so that it disengages from the main needle 3 after the main needle 3 resets. Next, the main needle 3 is inserted through a hole on the second side of the wound, and the auxiliary needle control module releases the auxiliary needle 1 after insertion. The main needle 3 resets, causing the auxiliary needle 1 to pass through the second side of the wound in the opposite direction. This process is repeated to connect the two sides of the wound with the suture 2. Tightening the suture 2 completes the suturing of the wound.

[0033] The function of the lifting and cutting module is to lift the human tissue on the first and second sides of the wound during suturing, making it easier for the main needle 3 and auxiliary needle 1, or the main needle 3 alone, to puncture the human tissue. Simultaneously, after puncture, the suture 2 is cut at an appropriate position, allowing it to remain in the wound. After cutting, the first end of the suture 2 connects to the auxiliary needle 1 and remains within the human tissue until the wound is completely healed or it degrades automatically. The second end of the suture 2 also remains within the human tissue. To prevent the second end of the suture 2 from loosening, a barb structure can be provided at the second end of the suture 2. This barb structure enhances the adhesion to the human tissue, preventing loosening before the wound heals.

[0034] At the same time, such as Figure 2 As shown, the auxiliary needle control module includes a locking seat 4 and a locking device 5 disposed within the locking seat 4. The auxiliary needle 1 has a locking groove 6, and the first end of the locking device 5 has a locking block 7 that matches the locking groove 6. The locking device 5 itself is made of an elastic material. When the auxiliary needle 1 is inserted into the locking device 5 from its first end, the conical surface (spiked portion) at the front end of the auxiliary needle 1 allows the locking block 7 to open, moving until the locking block 7 aligns with the locking groove 6, after which it elastically recovers and locks the auxiliary needle 1 in place. A control surface 8 is disposed at the second end of the locking device 5, and the control surface 8 is also inclined relative to the axial direction of the locking device 5. A control ball 9, which is spherical (or other shaped), is disposed at the control surface 8 and is connected to the inner end of the first control wire 10. When it is necessary to release the auxiliary needle 1, the operator pushes the control ball 9 through the first control wire 10, so that the control ball 9 moves along the control surface 8 toward the first end of the clamp 5, thereby opening the first end of the clamp 5, and the locking block 7 exits from the locking groove 6 to release the auxiliary needle 1, so that the main needle 3 can be combined with the auxiliary needle 1.

[0035] It should be noted that the first end of the locking device 5 is provided with multiple notches, which form a petal-like structure at the first end of the locking device 5, so that it can open smoothly under the action of the control ball 9.

[0036] It should be noted that the main needle 3 and auxiliary needle 1 are joined using a similar structure in this embodiment. A connecting block is provided at the rear of the auxiliary needle 1, and a connecting groove is provided at the front of the main needle 3. The connecting groove and connecting block are relatively thin and tapered, resulting in less limiting force compared to the connection between the auxiliary needle 1 and the retainer 5, thus facilitating the fixing and loosening of the auxiliary needle 1 by the retainer 5. Additionally, in this embodiment, the auxiliary needle 1 is provided with a suture connection groove 11. The first end of the suture 2 (after knotting) is inserted into the suture connection groove 11 to fix it to the auxiliary needle 1.

[0037] At the same time, such as Figure 3As shown, the outer end of the first control wire 10 passes through the first connecting rod 12 and extends to the first control assembly. The first control assembly includes a first control base 13 and a control button 14. The control button 14 is movably connected to the first control base 13 and can move relative to it. The outer end of the first control wire 10 is connected to the control button 14. When the operator presses the control button 14, the first control wire 10 (which has a certain rigidity) can be pushed, causing the control ball 9 at the inner end of the first control wire 10 to move towards the first end of the locking device 5, thus releasing the auxiliary needle 1. In a preferred embodiment, a first return spring 15 is also provided between the control button 14 and the first control base 13. When the operator releases the control button 14, the control button 14 automatically resets under the action of the first return spring 15, thereby resetting the control ball 9. Therefore, after the auxiliary needle 1 and the main needle 3 are combined, simply releasing the control button 14 controls the main needle 3 to drive the auxiliary needle 1, simplifying the operator's operation.

[0038] It should be noted that in this embodiment, the locking seat 4, the first connecting rod 12, and the first control seat 13 together form the outer shell support structure of the auxiliary needle control module. During installation, the locking seat 4 and the first connecting rod 12 pass through the first functional channel of the endoscope, and the locking seat 4 protrudes from the inner end of the endoscope, so that operation can be performed inside human tissue and control can be performed outside human tissue.

[0039] At the same time, such as Figure 4 As shown, the lifting and cutting module includes a lifting and cutting seat 16 and a lifting anchor 17. The first end of the lifting anchor 17 is equipped with a spike and is spirally arranged to smoothly anchor into and lift human tissue, facilitating puncture of human tissue by the main needle 3 and auxiliary needle 1, or by the main needle 3 alone. The second end of the lifting anchor 17 is connected to the first end of a second control wire 18 within the lifting and cutting seat 16. The second control wire 18 controls both the displacement and rotation of the lifting anchor 17, ensuring smooth anchoring into human tissue.

[0040] At the same time, such as Figure 5As shown, the outer end of the second control wire 18 passes through the second connecting rod 19 and extends to the second control assembly. The second control assembly includes a second control seat 20 and a control knob 21. The control knob 21 is movably connected to the second control seat 20 and can move and rotate relative to the second control seat 20. The outer end of the second control wire 18 is connected to the control knob 21. When the surgeon presses the control knob 21, the second control wire 18 can be pushed (the second control wire 18 has a certain rigidity), thereby causing the lifting anchor 17 at the inner end of the second control wire 18 to move outward from the lifting suture cutter seat 16 until it is inserted into the human tissue. Then, the control knob 21 is rotated synchronously to allow the lifting anchor 17 to rotate and anchor into the human tissue. Finally, the control knob 21 is pulled outward. Similarly, a second return spring 22 is also provided between the control knob 21 and the second control seat 20. When the surgeon releases the control knob 21, the control knob 21 will automatically return to its original position under the action of the second return spring 22, thereby resetting the lifting anchor 17. Of course, before that, the control knob 21 needs to be rotated in the opposite direction to separate it from the human tissue.

[0041] It should be noted that in this embodiment, the lifting wire cutter 16, the second connecting rod 19, and the second control seat 20 form the outer shell support structure of the lifting wire cutter module. During installation, the lifting wire cutter 16 and the second connecting rod 19 pass through the second functional channel of the endoscope, and the lifting wire cutter 16 protrudes from the inner end of the endoscope. Similarly, the operation is performed inside the human tissue and controlled outside the human tissue.

[0042] In this embodiment, a blade 23 is provided at the end of the suture-cutting base 16. Preferably, the blade 23 is arranged in a ring and integrally formed with the edge of the suture-cutting base 16. The blade 23 is used to cut the suture 2 so that the suture 2 after suturing is cut off and left at the wound position. Simultaneously... Figure 6 As shown, after suturing is completed, the first end of the suture 2 and the auxiliary needle 1 remain near the wound. The second end of the suture 2 (the second end after cutting) is located in the first functional channel of the endoscope, i.e., the channel where the auxiliary needle control module is located, and it extends to the outside without being cut. Therefore, when cutting the suture, the lifting anchor 17 is first extended relative to the lifting suture cutting seat 16 by controlling the knob 21, and then the entire endoscope is rotated. Since the suture 2 and the lifting anchor 17 have different centers of rotation, and the first end of the suture 2 does not move, the suture 2 will be wrapped around the lifting anchor 17. Then the lifting anchor 17 is rotated. Based on the spiral shape of the lifting anchor 17, the suture 2 can be firmly wrapped around. Then pull the control knob 21 outward to retract the lifting anchor 17 into the lifting suture cutter seat 16. When the suture 2 passes the edge of the lifting suture cutter seat 16, it will be directly cut by the sharp blade 23, so that the second end of the suture 2 is formed and retained near the wound. Afterward, the remaining suture 2 on the lifting anchor 17 can be recovered by removing the entire lifting suture cutter module.

[0043] Therefore, the lifting and suture-cutting module provided in this embodiment has both the functions of lifting human tissue and cutting suture 2. Compared with the setting of two modules, it can reduce the occupation of the valuable endoscope channel, save module installation steps, simplify the operation process, and thus improve the quality of surgery.

[0044] Other examples Figure 7 As shown, in a preferred embodiment, the entire device in this example is further provided with an operating table 24. The first control seat 13 of the auxiliary needle control module and the second control seat 20 of the lifting and cutting suture module are both fixed on the operating table 24. The operating table 24 can be fixed to the arm or other installation positions by the fixing part, which facilitates the operator to perform comprehensive operations. The first connecting rod 12 and the second connecting rod 19 extend outward from the bottom of the operating table 24 and are respectively inserted into the corresponding channels of the endoscope.

[0045] 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.

[0046] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
