Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, and in particular to a clip applier using a lock buckle type ligature. BACKGROUND

[0002] In endoscopic surgery, before the disconnection of tissues or blood vessels, the tissues or blood vessels need to be clamped and then disconnected. The commonly used method is to use a ligature clip to ligate and stop bleeding of the tissues or blood vessels. The commonly used ligature clip includes a bioabsorbable ligature clip and a non-absorbable plastic ligature clip. The clamping principle is that the upper and lower ends of the clip are buckled under the external force of the clip applier, so as to achieve the purpose of clamping.

[0003] Such ligature clips also have some defects in clinical use. For example, such ligature clips are used to hold and compress tissues or tube walls by means of hard double-armed V-shaped or U-shaped arms to achieve the purpose of ligation. The shear force on the tissues is large, and the tissues are easily cut when closed, especially when the tube wall is edematous. The risk of cutting and falling after surgery increases, resulting in consequences such as arterial intimal injury, bleeding, and bile fistula. In addition, it is difficult to clamp the ligature clip for thicker bundle-shaped tissues such as hepatic pedicle, splenic pedicle, and renal pedicle, and even a laparoscopic cutting stapler needs to be used.

[0004] Therefore, it is necessary to design a clip applier to achieve O-shaped centripetal ligation of tissues, uniform and firm ligation force on tissues, reduce shear injury of tissues or blood vessels, and be particularly suitable for O-shaped ligation of thicker bundle-shaped tissues such as hepatic pedicle, splenic pedicle, and renal pedicle. The operation is convenient, the cost is low, the surgical efficiency and safety can be improved. CONTENT OF THE INVENTION

[0033] This embodiment discloses a clamping tool using a locking cable tie. The clamping tool is used to tighten the cable tie 100, thereby allowing the cable tie 100 to form an O-shape and tighten the portion to be tied towards the center. To facilitate understanding of this embodiment, the cable tie 100 in this embodiment will first be described, such as... Figure 1 As shown, the cable tie 100 in this embodiment is a one-way serrated cable tie 100 with a locking hole at the head. Specifically, the cable tie 100 includes a locking hole frame 110 and a sheet-like strap 120. The locking hole frame 110 is provided with one-way serrations. One end of the sheet-like strap 120 is fixedly connected to the outer side of the locking hole frame 110, and the other end of the sheet-like strap 120 is configured as a free end 1201 (tip). Serrations are also provided on both sides of the sheet-like strap 120. The free end 1201 of the sheet-like strap 120 can be inserted into the locking hole frame 110 and tightened in one direction through the serrations. The cable tie 100 here can refer to the existing structure, and will not be described in detail in this embodiment.

[0034] like Figure 2 As shown, the clamping pliers using locking cable ties in this embodiment include a fixed handle 1, a sleeve 2, a movable handle 3, a trigger 4, a first clamping arm 5, a second clamping arm 6, a push block 7, a first pull rod 8, and a second pull rod 9.

[0035] like Figure 2 As shown, the upper end of the fixed handle 1 is located on one end of the sleeve 2, and the fixed handle 1 provides a handhold for the worker. The fixed handle 1 and the sleeve 2 can be designed as a single piece.

[0036] like Figure 2 As shown, the sleeve 2 is a slender hollow cylindrical tube with open ends. The specific length and inner diameter of the sleeve 2 can be designed according to actual conditions, and are not limited in this embodiment. In this embodiment, the left end and the right end of the sleeve 2 in the length direction are defined as the first end and the second end, respectively, and the fixing handle 1 is fixedly set at the first end of the sleeve 2.

[0037] like Figure 3As shown, the moving handle 3 is hingedly connected to the fixed handle 1 by a first pin shaft, and the fixed handle 1 and the moving handle 3 can be gripped by a hand, so that the first pull rod 8 is moved.

[0038] The fixed handle 1 is provided with a through slot 1a in the axial direction of the sleeve, for accommodating the trigger 4 and the moving handle 3.

[0039] In some embodiments, the middle position of the fixed handle 1 is provided with a slot 1a, which is provided on the fixed handle 1 in the axial direction of the sleeve, and the slot 1a can provide a avoiding position when the moving handle 3 is folded to the fixed handle 1, so that the moving handle 3 can be folded and gripped more to the fixed handle 1. In some preferred embodiments, a first reset elastic member (not shown) is provided between the fixed handle 1 and the moving handle 3, and the two ends of the first reset elastic member are connected to the fixed handle 1 and the moving handle 3 respectively, and the first reset elastic member can provide a reset force for the moving handle 3, and after the hand releases the moving handle 3, the moving handle 3 is reset under the action of the first reset elastic member, specifically: when the hand releases the moving handle 3, the first reset elastic member drives the moving handle 3 to open, so that the first pull rod 8 moves to the right, thereby driving the second clamping arm 6 to rotate away from the first clamping arm 5. In this embodiment, the first reset elastic member is preferably a torsional spring, which is coaxially sleeved on the first pin shaft, and the two ends of the torsional spring are connected to the fixed handle 1 and the moving handle 3 respectively.

[0040] As shown, Figure 3 The middle position of the trigger 4 is hingedly connected to the fixed handle 1 by a second pin shaft, and the upper end of the trigger 4 is located between the sleeve 2 and the moving handle 3. When the hand pulls the trigger 4, the second pull rod 9 connected to the trigger 4 drives the push block 7 to tighten the cable tie 100, wherein the trigger 4 is hingedly connected in the slot 1a of the fixed handle 1, and such design can make the trigger 4 as much as possible to be retracted into the slot 1a, so that the second pull rod 9 has a greater pushing stroke. In some preferred embodiments, a second reset elastic member is provided between the trigger 4 and the fixed handle 1, and the two ends of the second reset elastic member are connected to the trigger 4 and the fixed handle 1 respectively, and the second reset elastic member can provide a reset force for the trigger 4, and after the hand releases the trigger 4, the trigger 4 is reset under the action of the second reset elastic member, specifically: when the hand releases the trigger 4, the second reset elastic member drives the trigger 4 to open, and the trigger 4 drives the second pull rod 9 to move to the right, and at the same time, the push block 7 is reset to the initial position gradually close to the end of the sleeve 2. In this embodiment, the second reset elastic member is preferably a torsional spring, which is coaxially sleeved on the second pin shaft, and the two ends of the torsional spring are connected to the fixed handle 1 and the trigger 4 respectively.

[0041] As shown, Figure 4 and Figure 5As shown, the first clamping arm 5 is arranged at the second end of the sleeve 2 and extends along the axial direction of the sleeve 2, and the first clamping arm 5 can be fixedly arranged with the end surface of the sleeve 2 or integrally formed. One surface of the first clamping arm 5 facing the second clamping arm 6 is provided with a guide groove 5a, which is opened along the length direction of the first clamping arm 5, and the guide groove 5a of the first clamping arm 5 is used for placing the sheet-shaped band body 120 of the cable tie 100, and the guide groove 5a of the first clamping arm 5 facilitates guiding and limiting the sheet-shaped band body 120 of the cable tie 100, so as to realize the directional movement and tightening of the cable tie 100. The first clamping arm 5 is provided with a guide plate 501 at the position away from the end of the sleeve 2, and the length direction (i.e. the extension direction) of the guide plate 501 is perpendicular or nearly perpendicular to the first clamping arm 5, and the guide plate 501 is arranged to guide the sheet-shaped band body 120 of the cable tie 100 to bend at an angle of 90 degrees or nearly 90 degrees, so that the free end 1201 of the sheet-shaped band body 120 can smoothly pass through the locking hole frame 110 of the cable tie 100 upwards, thereby realizing the connection of the cable tie 100 to form an O shape. In the embodiment, the guide plate 501 is also provided with a guide groove 5a along the length direction, and the guide groove 5a on the guide plate 501 is in communication with the guide groove 5a on the first clamping arm 5, and the free end 1201 of the cable tie 100 is arranged in the guide groove 5a of the guide plate 501, and the guide groove 5a on the guide plate 501 facilitates stably guiding the sheet-shaped band body 120 of the cable tie 100 to pass through the locking hole frame 110 upwards, thereby realizing the stable tightening of the cable tie 100.

[0042] As shown in the drawings, Figure 6 As shown, one end of the second clamping arm 6 is hingedly connected with the second end of the sleeve 2 through a rotating shaft, and under the driving of the first pull rod 8, the second clamping arm 6 can rotate towards the first clamping arm 5 and perform a clamping action. The end of the second clamping arm 6 away from the sleeve 2 is provided with a mounting portion 601, which can be connected with the locking hole frame 110 of the cable tie 100, and when the second clamping arm 6 approaches the first clamping arm 5, the locking hole frame 110 corresponds to the guide groove 5a on the guide plate 501, so that the free end 1201 extending out of the guide groove 5a can pass through the locking hole frame 110 upwards.

[0043] As shown in the drawings, Figure 6As shown, in this embodiment, the mounting part 601 includes three side plates. The first side plate 6011 and the second side plate 6012 are both disposed on a surface of the second clamping arm 6 facing the first clamping arm 5. In this embodiment, the surface of the second clamping arm 6 facing the first clamping arm 5 is configured as the lower surface. The first side plate 6011 and the second side plate 6012 are disposed opposite to each other on the lower surface of the second clamping arm 6. The inner side of the third side plate 6013 is connected to the first side plate 6011 and the second side plate 6012. The three side plates form a limiting groove with three sides and one side missing. The position of the lock hole frame 110 is limited by the limiting groove. Specifically, the lock hole frame 110 is a rectangular frame with four outer sides. The three side plates are respectively attached to the three outer sides of the lock hole frame 110. The other side of the lock hole frame 110 is connected to the sheet-like strip 120. The inner side of the third side plate 6013 can be attached to and abut against the front side of the lock hole frame 110, thereby limiting the position of the lock hole frame 110 in the length direction of the first clamping arm 5.

[0044] It should be noted that, as Figure 6 As shown, the first side plate 6011 and the second side plate 6012 both extend forward along the length of the second clamping arm 6 to the outer side of the front end face of the second clamping arm 6. The third side plate 6013 is connected to the front of the front end face of the second clamping arm 6. The first side plate 6011 and the second side plate 6012 protrude to the front end face of the second clamping arm 6 so that after the lock hole frame 110 is installed on the mounting part 601, at least a part of the lock hole frame 110 can protrude from the front end of the second clamping arm 6, so that the free end 1201 of the cable tie 100 below can pass through the protruding part of the lock hole frame 110, thereby realizing the closure of the cable tie 100.

[0045] In this embodiment, the lower surface of the second clamping arm 6 is configured as the inner top surface of the aforementioned limiting groove, and the lower surface of the second clamping arm 6 is in contact with the upper surface of the lock hole frame 110.

[0046] In some embodiments, the mounting part 601 may also use only two side plates, namely a first side plate 6011 and a second side plate 6012. Both the first side plate 6011 and the second side plate 6012 are made of elastic material, which can elastically resist the two outer surfaces of the lock hole frame 110, thereby realizing the installation of the lock hole frame 110.

[0047] like Figure 2 As shown, the first pull rod 8 is slender and rod-shaped. The two ends of the first pull rod 8 are respectively hinged to the top of the second clamping arm 6 and the moving handle 3. When a person grips the fixed handle 1 and the moving handle 3, the second clamping arm 6 rotates and clamps towards the first clamping arm 5. When the moving handle 3 is released, the second clamping arm 6 automatically resets and rotates away from the first clamping arm 5 under the action of the first reset elastic element.

[0048] likeFigure 6 As shown, in some preferred embodiments, a connecting portion 602 is provided at one end of the second clamping arm 6 near the sleeve 2. The length direction of the connecting portion 602 is perpendicular to the length direction of the second clamping arm 6, that is, the connecting portion 602 extends in a direction perpendicular to the second clamping arm 6, so that the connecting portion 602 and the second clamping arm 6 form an L-shaped structure. One end of the first pull rod 8 is hinged to the connecting portion 602, that is, the first pull rod 8 is hinged to the second clamping arm 6 through the connecting portion 602. It can be understood that the first pull rod 8 can be directly hinged to the second clamping arm 6, or it can be hinged to the second clamping arm 6 through the connecting portion 602. The advantage of the first pull rod 8 being hinged to the second clamping arm 6 through the connecting portion 602 is that it makes it easier for a person to grip the moving handle 3, reduces the force required for a person to grip the moving handle 3, thereby reducing the operating burden of the operator and improving the flexibility of the structure.

[0049] like Figure 7 As shown, the push block 7 is slidably disposed in the guide groove 5a of the first clamping arm 5. The push block 7 can slide in the guide groove 5a along the length direction of the first clamping arm 5. The push block 7 can move toward the cable tie 100 under the push of the second pull rod 9 and push the cable tie 100 to tighten. Since the cable tie 100 on the first clamping arm 5 is restricted by the guide groove 5a, the sheet-like strip 120 of the cable tie 100 can only pass through the lock hole frame 110 and converge and tighten inward under the push of the push block 7.

[0050] like Figure 2 As shown, the two ends of the second pull rod 9 are hinged to the back of the push block 7 and the top of the trigger 4, respectively. When the trigger 4 is pulled by hand, the top of the trigger 4 drives the second pull rod 9 to move toward the push block 7. The second pull rod 9 then pushes the push block 7 toward the cable tie 100. When the trigger 4 is released by hand, the second reset elastic element can drive the trigger 4 to reset. At the same time, the trigger 4 drives the second pull rod 9 and the push block 7 to reset. At this time, the push block 7 resets in a direction away from the guide plate 501.

[0051] The working principle of the clamp in this embodiment is as follows: Figure 7 As shown:

[0052] With the moving handle 3 and trigger 4 released, the locking hole frame 110 of the cable tie 100 is inserted into the mounting part 601 at the front end of the second clamping arm 6. Then, the sheet-like strap 120 of the cable tie 100 is bent and installed in the guide groove 5a of the first clamping arm 5 and the guide plate 501. The free end 1201 of the sheet-like strap 120 is located in the guide groove 5a of the guide plate 501.

[0053] When it is needed to ligate tissue or blood vessel, the first and second arms 5 and 6 are extended to the two sides of the tissue or blood vessel to be ligated, the fixed handle 1 and the moving handle 3 are moved towards each other, the moving handle 3 drives the first pull rod 8 in the sleeve 2 to move backward, the second arm 6 connected with the first pull rod 8 is pulled to rotate towards the first arm 5 (the rotating direction of the first arm is shown by the arrow F2), so that the locking hole frame 110 of the ligature 100 is moved above the guide plate 501;

[0054] Then the trigger 4 is pulled, the second pull rod 9 drives the push block 7 to slide towards the ligature 100 under the pushing of the trigger 4 (the moving direction of the push block is shown by the arrow F1), the push block 7 pushes and squeezes the sheet-shaped band 120 of the ligature 100, and the free end 1201 of the ligature 100 can only pass through the locking hole frame 110 upward and make the ligature 100 tighten due to the limitation of the guide groove 5a, wherein the one-way sawtooth of the ligature 100 limits the ligature 100 to only tighten in one direction and cannot reverse, and the tissue wrapped by the ligature 100 is gradually locked and ligated in O shape, and the tissue is uniformly stressed;

[0055] Finally, the trigger 4 is released, the second elastic reset member drives the trigger 4 and the second pull rod 9 to reset, so that the push block 7 is also reset backward under the driving of the second pull rod 9; the moving handle 3 is released, the first elastic reset member drives the moving handle 3 to reset, the moving handle 3 drives the first pull rod 8 to move, the first pull rod 8 drives the second arm 6 to rotate away from the first arm 5, at the same time, the locking hole frame 110 is separated from the mounting part 601 on the second arm 6, and the first arm 5 and the second arm 6 are thus separated from the ligature 100.

[0056] The embodiment also discloses a ligature device, which comprises a ligature (for example, the ligature 100) and the clip applier for tightening the ligature, the ligature (the ligature 100) comprises a locking hole frame 110 and a sheet-shaped band 120, the locking hole frame 110 is provided with a one-way sawtooth, one end of the sheet-shaped band 120 is fixedly connected with the outer side of the locking hole frame 110, the other end of the sheet-shaped band 120 is configured as a free end 1201 (a pointed end), both sides of the sheet-shaped band 120 are also provided with sawteeth, the free end 1201 of the sheet-shaped band 120 can be inserted into the locking hole frame 110 and tightened in one direction through the sawteeth, and the contact surface of the ligature and the tissue is provided with a longitudinal fine-tooth structure, which is similar to the fine-tooth structure of a non-injury vascular clamp, can prevent slipping and does not damage the tissue.

[0057] The above merely describes a specific implementation of the present application. Those skilled in the art can clearly understand the specific working processes of the system, modules and units described above for the convenience and brevity of description, and can refer to the corresponding processes in the foregoing method embodiments, which will not be described herein again. It should be understood that the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
