AI Technical Summary

Technical Problem

The status feedback structure of the existing continuous ligation clamp is prone to failure, resulting in limited use times and is unable to effectively remind users to reach key nodes.

Method used

A state feedback device is designed, including a curved touch plate, a reset bottom plate, a fixed swing arm and a sliding swing arm. Through the cycle of the sliding swing arm between the fully bottoming, fully popping and retracting locking state, it provides clear force feedback and a sense of stuttering, reminding the user to turn the wrench to a key node.

Benefits of technology

By enhancing the expansion and contraction of the state feedback device, the thickness of the arc-shaped contact plate and the stability of the structural stability are improved, ensuring that the continuous ligation clamp can still provide feedback during multiple uses, and avoiding the problem of too small opening of the ligation clamp caused by missing key nodes.

Abstract

The invention relates to a continuous ligation clip which at least comprises a clip applying pipe preassembled with a ligation clip, a handheld part, a wrench and a state feedback device, and the state feedback device comprises an arc-shaped touch plate, a reset bottom plate, a fixed swing arm and a sliding swing arm. When the fixed swing arm moves forwards along with the wrench, the sliding swing arm is squeezed by the arc-shaped touch plate to achieve a complete grounding state, and when the sliding swing arm moves to the limit position of the front end, the sliding swing arm achieves a complete pop-up state. When the fixed swing arm retreats along with the wrench, the sliding swing arm passes through a gap between the pair of arc-shaped touch plates, and when the fixed swing arm moves to the rear end, the sliding swing arm is squeezed by the reset bottom plate to achieve a retraction locking state. According to the running-firing ligation clip, when the sliding swing arm is in a complete grounding state, the sliding swing arm keeps abutting against the arc-shaped touch plate and slides along the arc-shaped touch plate, and corresponding damping is generated between the sliding swing arm and the arc-shaped touch plate to provide clear force feedback for a user.

Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a continuous hair ligation clip. Background Art

[0002] When using a ligation clamp for surgery, a continuous ligation clamp is required. The continuous ligation clamp is a ligation clamp pre-installed in a clamp tube, and a wrench for driving the ligation clamp is provided in the handle. When the wrench is grasped by hand, the ligation clamp is driven by the driving mechanism provided in the clamp tube to perform surgery. During the movement of the wrench, the following most critical nodes are passed: the ligation clamp moves from the clamp tube to the jaws and opens to the maximum angle. At this time, the continuous ligation clamp should give sufficient feedback to remind the user, otherwise once this critical node is missed, the ligation clamp has begun to gradually close, which may cause the ligation clamp opening to be too small to clamp the blood vessel.

[0003] The prior art has disclosed some preliminary designs. Application No. 201920433577X, patent name "A patent with state feedback function" records the following scheme: damping is generated when the guide post and the positioning protrusion at its end slide on the inner wall of the guide rail. However, the above scheme has the following problems: the guide rail is thin, because its guide post and the positioning protrusion must slide on the inside of the guide rail during the upward stage (the guide post elastically deforms and bends to allow it to slide smoothly into the inside of the guide rail), and after it pops out from the upper end of the guide rail, the positioning protrusion can only go down from the outside of the guide rail (when the guide post is fully straightened, it is larger than the outer diameter of the guide rail). Due to the limited elastic deformation of the guide post, the thickness of the guide rail is very limited, and the above structure is very easy to fail after multiple uses.

[0004] Therefore, it is necessary to design a brand-new state feedback device that can be used multiple times and a continuous ligation clip with the same. Summary of the invention

[0005] A continuous ligation clip comprises at least a clip applicator tube pre-installed with a ligation clip, a hand-held portion, a wrench hinged on the left side of the hand-held portion, and a state feedback device, wherein the state feedback device comprises:

[0006] There are two arc-shaped touch panels, one at the upper end and one at the lower end of the hand-held part;

[0007] A reset bottom plate is arranged in the hand-held part and behind the arc-shaped touch plate;

[0008] A fixed swing arm is arranged on the right side of the wrench; the fixed swing arm comprises a swing arm base in a rectangular shape, a swing arm inner cavity arranged on the right side of the swing arm base, a spring slot arranged at the lower edge of the swing arm inner cavity, a pop-up compression spring arranged in the spring slot, and a limit plug arranged on the right side below the swing arm inner cavity;

[0009] A sliding swing arm is slidably arranged in the fixed swing arm; the sliding swing arm comprises a telescopic base slidably arranged in the inner cavity of the swing arm, a receiving cutout arranged on the left side above the telescopic base, a limiting slot arranged on the right side of the lower end of the telescopic base and cooperating with a limiting plug, a telescopic thin shaft arranged on the right side of the telescopic thin shaft, an end stopper arranged on the right side of the telescopic thin shaft, and a spring stopper arranged below the telescopic base and inserted into the spring slot, wherein the spring stopper is located on the right side of the pop-up compression spring;

[0010] When the fixed swing arm moves forward with the wrench, the sliding swing arm is squeezed by the arc-shaped touch plate to achieve a completely bottomed state, and when it moves to the front extreme position, the sliding swing arm reaches a completely popped-out state;

[0011] When the fixed swing arm retreats with the wrench, the sliding swing arm passes through the gap between a pair of arc-shaped touch plates. When moving to the rear end, the sliding swing arm is squeezed by the reset bottom plate to achieve a retracted locking state.

[0012] As a further implementation:

[0013] The continuous ligation clamp also includes:

[0014] A fixed lock head is arranged on the left side above the inner cavity of the swing arm, and a fixed inclined plane inclined from the upper right to the lower left is also arranged on the right side of the fixed lock head;

[0015] The sliding unlocker comprises a spring insertion hole arranged laterally above the swing arm base, a lower through hole arranged on the left side of the lower end of the spring insertion hole, an unlocking compression spring arranged on the right half of the spring insertion hole, a spring stopper slidably arranged on the left half of the spring insertion hole, a sliding clamping body arranged below the spring stopper and passing through the lower through hole, and an unlocking inclined surface inclined from the upper left to the lower right arranged on the left side of the sliding clamping body;

[0016] The spring-loaded lock comprises a spring-loaded longitudinal cavity arranged in the telescopic base, a spring-loaded opening arranged on the left side of the upper end of the spring-loaded longitudinal cavity, a bottom insert tube arranged at the lower end of the spring-loaded longitudinal cavity, a lock compression spring arranged at the bottom of the inner cavity of the bottom insert tube, a lock slider slidably arranged in the spring-loaded longitudinal cavity, a lock body arranged at the upper end of the lock slider and passing through the spring-loaded opening, a lock inclined surface inclined from the upper right to the lower left arranged on the left side of the lock body, a guide plug hole formed at the lower end of the lock slider and sleeved on the outer edge of the bottom insert tube, and a spring core rod arranged at the lower end of the lock slider and inserted in the inner cavity of the bottom insert tube, wherein the spring core rod abuts against the top of the lock compression spring;

[0017] A resistance adjusting device, the resistance adjusting device includes a rotation-stopping side hole arranged on the right side above a spring insertion hole, a narrow-diameter through hole arranged on the right side of the spring insertion hole, a rotating core shaft rotatably arranged in the narrow-diameter through hole, a rotating terminal arranged on the right side of the rotating core shaft, a rotating inner disk arranged on the left side of the rotating core shaft, an externally threaded rod arranged on the left side of the rotating inner disk, an internally threaded cylinder screwed on the externally threaded rod, and a rotation-stopping plug arranged above the internally threaded cylinder and passing through the rotation-stopping side hole.

[0018] Beneficial effects;

[0019] The continuous ligation clamp described in this case has a sliding swing arm of a state feedback device that can cycle between a retracted locking state, a fully bottomed state, and a fully popped-out state. Compared with the prior art solution that purely relies on the elastic deformation of the guide column, the telescopic range of the state feedback device in this case is greatly improved, thereby allowing the thickness of the arc-shaped touch plate to be greatly increased, and the structural strength is more stable.

[0020] The continuous ligation clamp described in this case, when the sliding swing arm is in a completely bottomed state, maintains contact with the arc-shaped touch plate and slides along the arc-shaped touch plate, and the corresponding damping is generated between the two to give the user clear force feedback. Furthermore, when the locking groove and the end stopper of the sliding swing arm are locked and matched, a crisp clicking sound can be generated and a momentary sense of stuck can be given, clearly reminding the user that the wrench has been rotated to a critical node.

[0021] In the continuous ligation clamp described in this case, the reset base plate can assist the sliding swing arm of the status feedback device to perform initial retraction to reach a retracted locking state. In this state, the distal end of the sliding swing arm cooperates with the guide slope, and the guide slope can squeeze the sliding swing arm to a completely bottoming state.

[0059] As a further implementation:

[0060] A swing arm notch 66 for accommodating a rotating terminal is formed above the right end surface of the fixed swing arm 6 .

[0061] As a further implementation:

[0062] The upper and lower ends of the end stopper rod 55 are flush with the upper and lower ends of the swing arm base 61 respectively;

[0063] The longitudinal dimension of the end stopper 55 is larger than the gap between the pair of arc-shaped contact plates 8;

[0064] The longitudinal dimension of the telescopic thin shaft 54 ​​is smaller than the gap between the pair of arc-shaped contact plates 8 .

[0065] As a further implementation:

[0066] A guiding slope 81 sloping from the upper left to the lower right is provided at the lower edge of the arc-shaped touch plate 8 , and a locking groove 82 for locking the end stopper 55 is provided at the upper left side of the arc-shaped touch plate 8 .

[0067] As a further implementation:

[0068] The inner arc surface of the arc-shaped touch plate 8 is densely covered with micro-small teeth.

[0069] The continuous ligation clamp described in this case has a sliding swing arm 5 that can cycle between a retracted locking state p, a fully bottomed state q, and a fully popped-out state r:

[0070] Retraction locking state p:

[0071] See the instruction manual Figure 8 , 9 , press the sliding swing arm 5 to make it slide to the left to overcome the damping of the pop-up compression spring 64, until the fixed inclined surface 41 squeezes the lock body 26 to make it overcome the damping of the lock compression spring 24 and move downward, until the lock body 26 passes over the fixed inclined surface 41 and is stuck on the left side of the fixed lock 4;

[0072] Complete bottoming state q:

[0073] See the instruction manual Fig.10 , continue to press the sliding swing arm 5 to move it to the left, so that the spring lock head 2 passes over the sliding clamp body 35 and the unlocking inclined surface 36, and the sliding swing arm 5 is directly inserted into the leftmost side of the fixed swing arm 62;

[0074] Fully pop-up state r:

[0075] Reference Manual Attached Fig.11 , 12 After stopping pressing, the pop-up compression spring 64 drives the sliding swing arm 5 to pop up to the right, and the lock body 26 drives the spring stopper 34, the sliding clamp body 35, and the unlocking inclined surface 36 to overcome the damping of the spring stopper 33 and move to the right until it abuts against the fixed lock 4 and stops. The lock body 26 continues to move to the right with the sliding swing arm 5, and the unlocking inclined surface 36 squeezes the lock body 26 to overcome the damping of the lock compression spring 24 and go down, until the lock body 26 continuously passes the unlocking inclined surface 36 and the fixed inclined surface 41 and pops out completely.

[0076] It should be noted that the elastic force of the pop-up compression spring 64 is much greater than the elastic force of the lock compression spring 24 , and the elastic force of the lock compression spring 24 is much greater than the elastic force of the unlocking compression spring 33 .

[0077] The fixed swing arm 6 and the sliding swing arm 5 move as follows during the cycle of swinging with the wrench 93:

[0078] As the instruction manual Figure 2 As shown, the sliding swing arm 5 is in a retracted locking state p;

[0079] As the instruction manual Figure 3 As shown, pressing the wrench 93 backward drives the fixed swing arm 6 and the sliding swing arm 5 upward, and the guiding inclined surface 81 squeezes the sliding swing arm 5 to make it continue to retract, reaching the completely bottoming state q;

[0080] Since the sliding swing arm 5 is rigidly connected to the fixed swing arm 6 at this time, and the end stop rod 55 of the sliding swing arm 5 abuts against the inner walls of the upper and lower arc-shaped touch plates 8 to generate stable damping, when the end stop rod 55 slides into the locking groove 82, the clicking sound and instantaneous jamming feeling generated can remind the user.

[0081] As the instruction manual Figure 4 , 5 As shown:

[0082] After the sliding swing arm 5 passes the arc-shaped touch plate 8, it loses the squeezing force source and then pops out to reach the fully popped-out state r;

[0083] The telescopic thin shaft 54 ​​is smaller in the longitudinal direction than the end stopper 55, so that it can slide downward through the longitudinal gap between the pair of arc-shaped touch plates 8;

[0084] As the instruction manual Figure 6 , 7 As shown:

[0085] The fixed swing arm 6 and the sliding swing arm 5 continue to swing downward, and the sliding swing arm 5 is squeezed and retracted by the reset bottom plate 7;

[0086] The sliding swing arm 5 reaches the retracted state p.
