[0001] The present invention relates to the technical field of medical instruments, and in particular to an endoscope-assisted needle control and wire-lifting and cutting device. Background Art

[0002] Minimally invasive surgery is a type of surgery with tiny incisions. Due to the small incision, minimally invasive surgery can reduce the patient's blood loss during the operation and reduce the patient's pain after the operation. During the operation, the surgeon places an endoscope into the patient's body and observes the patient's internal conditions through the endoscope. Under the action of the endoscope, the surgeon can perform the corresponding surgical operations and postoperative sutures in the patient's body.

[0003] During minimally invasive surgery, there is a widespread demand for devices that can close wounds with sutures, similar to open laparotomy. Many of the existing related technologies are unable to perform continuous sutures on wounds at one time, and require multiple installations of suture devices. In some devices that can perform continuous sutures on wounds at one time, the control of fixing and releasing the auxiliary needle is not very smooth and reliable. At the same time, after the wound is sutured, the cutting and handling of the sutures are more troublesome and need to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a device with reasonable structure and convenient operation for operators in view of the shortcomings of the above-mentioned background technology.

DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1 As shown, an embodiment of the present invention provides an endoscopic auxiliary needle control and lifting and cutting thread device, including an auxiliary needle control module and a lifting and cutting thread module. Among them, the auxiliary needle control module is used to fix and release the auxiliary needle 1, and the auxiliary needle 1 is connected to the suture 2. The auxiliary needle 1 is connected to the main needle 3 in the initial state of suturing. During suturing, the main needle 3 and the auxiliary needle 1 are pierced and inserted from the first side of the wound, and then the auxiliary needle 1 is inserted into the auxiliary needle control module. The auxiliary needle control module fixes the auxiliary needle 1 so that the auxiliary needle 1 is separated from the main needle 3 after the main needle 3 is reset; then the main needle 3 is pierced and inserted from the second side of the wound, and the auxiliary needle control module releases the auxiliary needle 1 after the auxiliary needle 1 is inserted. The reset of the main needle 3 drives the auxiliary needle 1 to pass through the second side of the wound in the opposite direction; the above process is repeated to make the suture 2 connect the two sides of the wound, and the suture 2 is tightened to complete the suturing of the wound.

[0033] The function of the lifting and thread cutting module is to lift the human tissue on the first and second sides of the wound during the suturing process to facilitate the main needle 3 and the auxiliary needle 1, or the main needle 3 alone to puncture the human tissue. At the same time, after the puncture is completed, the suture 2 is cut at the appropriate position so that the suture 2 can remain at the wound position. After cutting, the first end of the suture 2 is connected to the auxiliary needle 1, which will remain in the human tissue until the wound is completely healed or automatically degraded, and the second end of the suture 2 will also remain in the human tissue. In order to prevent the second end of the suture 2 from loosening, a barb structure can be set at the second end of the suture 2, relying on the barb structure to improve the degree of integration with the human tissue, and it will not loosen before the wound heals.

[0034] At the same time Figure 2 As shown, the auxiliary needle control module includes a snap-fit ​​seat 4 and a snap-fit ​​device 5 arranged in the snap-fit ​​seat 4. Among them, a snap-fit ​​slot 6 is arranged on the auxiliary needle 1, and a snap-fit ​​block 7 matching the snap-fit ​​slot 6 is arranged at the first end of the snap-fit ​​device 5, and the snap-fit ​​device 5 itself is made of elastic material. When the auxiliary needle 1 is inserted into the snap-fit ​​device 5 from the first end of the snap-fit ​​device 5, the conical surface (spike portion) at the front end of the auxiliary needle 1 can open the snap-fit ​​block 7, so that the snap-fit ​​block 7 moves to align with the snap-fit ​​slot 6 and then elastically recovers to snap the auxiliary needle 1. A control surface 8 is arranged at the second end of the snap-fit ​​device 5, and the control surface 8 is also inclined relative to the axial direction of the snap-fit ​​device 5. At the same time, a control ball 9 is arranged at the control surface 8, and the control ball 9 is spherical (or other shapes) and connected to the inner end of the first control wire 10. When the auxiliary needle 1 needs to be loosened, the operator pushes the control ball 9 through the first control wire 10 to move the control ball 9 along the control surface 8 toward the first end of the coupler 5, thereby opening the first end of the coupler 5, and the block 7 withdraws from the slot 6 to loosen the auxiliary needle 1, making it easier for the main needle 3 to be combined with the auxiliary needle 1.

[0035] It should be noted that the first end of the snap-fit ​​device 5 is provided with a plurality of notches, through which the first end of the snap-fit ​​device 5 forms a petal-like structure, so that it can be smoothly opened under the action of the control ball 9.

[0036] It should be noted that the combination of the main needle 3 and the auxiliary needle 1 in this embodiment also adopts a similar structure, that is, a combination block is provided at the rear of the auxiliary needle 1, and a combination groove is provided at the front of the main needle 3. Of course, the thickness of the combination groove and the combination block is small and conical, and the limiting force is smaller than that of the auxiliary needle 1 and the clamp 5, which facilitates the clamp 5 to fix and release the auxiliary needle 1. In addition, in this embodiment, a suture connection groove 11 is provided on the auxiliary needle 1, and the first end of the suture 2 (after knotting) is inserted into the suture connection groove 11 to be fixed to the auxiliary needle 1.

[0037] At the same time Figure 3As shown, the outer end of the first control wire 10 passes through the first connecting rod 12 and then extends to the first control assembly. The first control assembly includes a first control seat 13 and a control button 14. The control button 14 is movably connected to the first control seat 13 and can move relative to the first control seat 13. 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 can be pushed (the first control wire 10 has a certain rigidity), so that the control ball 9 at the inner end of the first control wire 10 moves toward the first end of the clamp 5, and the auxiliary needle 1 is released. As a preferred embodiment, a first reset spring 15 is also provided between the control button 14 and the first control seat 13. When the operator releases the control button 14, the control button 14 will automatically reset under the action of the first reset spring 15, so that the control ball 9 is reset. Therefore, after the auxiliary needle 1 is combined with the main needle 3, only the control button 14 needs to be released to control the main needle 3 to drive the auxiliary needle 1 to move, which simplifies the operator's operation.

[0038] It should be noted that, in this embodiment, the snap-fit ​​seat 4, the first connecting rod 12, and the first control seat 13 together constitute the outer shell support structure of the auxiliary needle control module. When installed, the snap-fit ​​seat 4 and the first connecting rod 12 pass through the first functional channel of the endoscope, and the snap-fit ​​seat 4 is passed through the inner end of the endoscope, so as to operate in the human tissue and control outside the human tissue.

[0039] At the same time Figure 4 As shown, the lifting and thread cutting module includes a lifting and thread cutting seat 16 and a lifting anchor 17. Among them, the first end of the lifting anchor 17 is provided with a spike portion, and is spirally arranged so as to smoothly anchor into human tissue and lift it, so as to facilitate the main needle 3 and the auxiliary needle 1, or the main needle 3 alone to puncture the human tissue. The second end of the lifting anchor 17 is connected to the first end of the second control wire 18 in the lifting and thread cutting seat 16. The second control wire 18 controls the displacement of the lifting anchor 17 on the one hand, and controls the rotation of the lifting anchor 17 on the other hand, so that the lifting anchor 17 is smoothly anchored into human tissue.

[0040] At the same time 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 operator presses the control knob 21, the second control wire 18 can be pushed (the second control wire 18 has a certain rigidity), so that the lifting anchor 17 at the inner end of the second control wire 18 moves to the outside of the lifting and cutting wire seat 16 until it is inserted into the human tissue, and then the control knob 21 is synchronously rotated to allow the lifting anchor 17 to rotate and anchor into the human tissue, and then the control knob 21 is pulled outward. Similarly, a second reset spring 22 is also provided between the control knob 21 and the second control seat 20. When the operator releases the control knob 21, the control knob 21 will automatically reset under the action of the second reset spring 22, thereby resetting the lifting anchor 17. Of course, before this, the control knob 21 needs to be rotated in the opposite direction to separate from the human tissue.

[0041] It should be noted that, in this embodiment, the lifting and cutting thread seat 16, the second connecting rod 19, and the second control seat 20 constitute the outer shell support structure of the lifting and cutting module. During installation, the lifting and cutting thread seat 16 and the second connecting rod 19 pass through the second functional channel of the endoscope, and the lifting and cutting thread seat 16 is passed through the inner end of the endoscope. It can also be operated inside the human tissue and controlled outside the human tissue.

[0042] In this embodiment, a blade 23 is provided at the end of the lifting and cutting seat 16. Preferably, the blade 23 is distributed in an annular shape and is integrally formed with the edge of the lifting and cutting seat 16. The blade 23 is used to shear the suture 2 so that the suture 2 after suturing is completed is cut off and retained at the wound position. Figure 6 As shown, after the suturing is completed, the first end of the suture 2 and the auxiliary needle 1 remain near the wound, and the second end of the suture 2 (the second end after being cut) is located in the first functional channel of the endoscope, that is, the channel where the auxiliary needle control module is located, and is not cut at this time but extends to the outside. Therefore, when cutting the thread, the lifting anchor 17 is first extended relative to the lifting thread cutting seat 16 through the control knob 21, and then the entire endoscope is rotated. Since the suture 2 and the lifting anchor 17 have different rotation centers, and the first end of the suture 2 is stationary, the suture 2 will be wound around the lifting anchor 17, and then the lifting anchor 17 is rotated. Based on the spiral shape of the lifting anchor 17, the suture 2 can be firmly wound. Then, the control knob 21 is pulled outward to retract the lifting anchor 17 into the lifting thread cutting seat 16. The suture 2 will be directly cut by the sharp blade 23 when passing the edge of the lifting thread cutting seat 16, so that the second end of the suture 2 is formed and retained near the wound. The lifting thread cutting module can be taken out as a whole to recover the remaining suture 2 on the lifting anchor 17.

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

[0044] In addition, Figure 7 As shown, as a preferred embodiment, the entire device in this embodiment is also 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 thread module are fixed on the operating table 24, and the operating table 24 can be fixed on the arm or other installation positions through the fixing part, so as to facilitate 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 may be arbitrarily combined. To make the description concise, 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 only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
