Abstract

This utility model relates to a safety buckle for cable ties, comprising a strip-shaped soft strap body, a retaining ring at one end of the strap body, a first buckle tooth inside the retaining ring, and teeth along the length of the strap body. When the open end of the strap body passes through the retaining ring to form a ring, the teeth engage with the first buckle tooth for limiting the movement. The teeth can also move forward along the first buckle tooth and lock in the opposite direction. The buckle also includes a ring-shaped safety buckle with a second buckle tooth inside. The safety buckle passes through the open end of the strap body and is engaged with the second buckle tooth for limiting the movement. The teeth can also move forward along the second buckle tooth and lock in the opposite direction. When there is a distance between the safety buckle and the retaining ring, the safety buckle acts as an auxiliary structure for the operator to apply force on the strap body. When the safety buckle abuts the retaining ring, the safety buckle and the retaining ring form a double limiting and locking state relative to the teeth. This utility model can greatly improve the safety of cable ties and provides anti-slip assistance during operation through the safety buckle.

Description

Technical Field

[0001] This utility model relates to a medical device, and more particularly to a cable tie safety buckle. Background Technology

[0002] In order to address male reproductive issues such as phimosis or paraphimosis, an increasing number of men are choosing circumcision to avoid the negative impacts on their health and sex life. Circumcision involves using a circumcision stapler. First, the foreskin is positioned on the stapler's attachment ring. One method of fixation is using an inner ring on the inside and a ligature on the outside. The tightened ligature, combined with the annular groove on the inner ring, holds the foreskin in the desired position. Then, the stapler's cutting blade precisely cuts the foreskin. Although the ligature's structure and application are very mature and rarely come loose, if the ligature's locking teeth accidentally loosen, it will affect the overall efficiency of the procedure and may even cause harm to the patient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bandage safety buckle. The design of the safety buckle forms a double structure to lock the bandage, which exponentially increases the safety factor of the bandage and can greatly reduce the risks during surgery.

[0004] This utility model adopts the following technical solution: a binding strap safety buckle, including a strip-shaped soft strap body, a retaining ring at one end of the strap body, a first buckle tooth inside the retaining ring, and teeth along the length of the strap body. When the open end of the strap body passes through the retaining ring to form a ring, the teeth are locked by the first buckle tooth for limiting, and the teeth can move forward along the first buckle tooth to lock in the opposite direction. It also includes a ring-shaped safety buckle, a second buckle tooth inside the safety buckle. The safety buckle passes through the open end of the strap body and is locked by the second buckle tooth for limiting, and the teeth can move forward along the second buckle tooth to lock in the opposite direction. When there is a distance between the safety buckle and the retaining ring, the safety buckle serves as an auxiliary structure for the operator to apply force on the strap body. When the safety buckle abuts against the retaining ring, the safety buckle and the retaining ring form a double limiting and locking state relative to the teeth.

[0005] As an improvement, one side of the safety buckle has a thickened outer wall to facilitate the operator's application of force.

[0006] As an improvement, one side of the safety buckle has a second extension bar to facilitate the operator's application of force.

[0007] As an improvement, the outer side of the retaining ring is provided with a first extension bar to facilitate the operator to apply force.

[0008] As an improvement, the distal end of the first extension has a larger-sized protrusion.

[0009] As an improvement, a blocking plate is provided on the end of the belt where the retainer is located. When the open end of the belt passes through the retainer to form a ring, the blocking plate and the inner side of the belt together form an inner wall of the ring.

[0010] As an improvement, the thickness of the blocking sheet gradually decreases as it extends outward.

[0011] As an improvement, the belt body gradually decreases in size from the position of the belt teeth towards the open end, which makes it easier for the open end of the belt body to pass through the retaining ring so that the belt teeth can reach the retaining ring.

[0012] The beneficial effects of this invention are as follows: The safety buckle design, combined with the retaining ring, creates a double-locking limit at the toothed position of the strap, significantly improving the safety of the ligature. If the probability of a problem occurring at a single locking position is one in a thousand, then the probability of a problem occurring at a double locking position is one in a thousand squared, or one in a million. This exponentially increases the safety factor of the safety buckle during circumcision surgery, ensuring the smooth progress of the procedure. Furthermore, since the strap itself is made of a relatively slippery material, the safety buckle, before being pushed to lock against the retaining ring, acts as an enlarged block structure on the strap, allowing the surgeon to apply force and providing anti-slip assistance during operation.

[0017] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 , 2As shown in Figure 3, this is a specific embodiment of the safety buckle of the present invention. This embodiment includes a strip-shaped soft strap 1, with a retaining ring 2 at one end of the strap 1. A first buckle tooth 21 is provided inside the retaining ring 2. Teeth 3 are provided on the strap 1 along its length. When the open end of the strap 1 passes through the retaining ring 2 and is wound into a ring, it is locked by the first buckle tooth 21 by the teeth 3. The teeth 3 can move forward along the first buckle tooth 21 and lock in the opposite direction. It also includes a ring-shaped safety buckle 4, with a second buckle tooth 41 inside the safety buckle 4. The safety buckle 4 passes through the open end of the strap 1 and is locked by the second buckle tooth 41 by the teeth 3. The teeth 3 can move forward along the second buckle tooth 41 and lock in the opposite direction. When there is a distance between the safety buckle 4 and the retaining ring 2, the safety buckle 4 serves as an auxiliary structure for the operator to apply force on the strap 1. When the safety buckle 4 abuts against the retaining ring 2, the safety buckle 4 and the retaining ring 2 form a double limiting and locking state relative to the teeth 3.

[0019] When using this invention, the physician first places the glans penis at the foreskin fixing ring, then rolls the foreskin to the outside of the foreskin fixing ring. The position of the foreskin is adjusted to determine the relative positioning position of the foreskin and the foreskin fixing ring. After the position is determined, the ligature forms a ring around the foreskin from the outside to complete the initial positioning. The physician can finely adjust the position of the frenulum to prevent the frenulum from entering the cutting and suturing area, and then tighten the ligature to complete the fixation of the foreskin. In practice, the doctor first passes the open end of the strap 1 through the retaining ring 2 to form a loop, and then uses the strap teeth 3 to lock it at the first buckle 21 for limitation. The safety buckle 4 is then placed on the strap 1 and locked at the second buckle 41 by the strap teeth 3. The strap 1 itself is relatively thin and smooth. The safety buckle 4 and retaining ring 2 can initially be kept at a distance, with the safety buckle 4 acting as a relatively large anti-slip aid structure for the doctor to lean on when applying force. After adjusting the position of the foreskin, the doctor first applies force to tighten the retaining ring 2, causing the strap 1 to lock the foreskin. Then, the doctor moves the safety buckle 4 until it contacts the retaining ring 2, creating a double-limiting and locking state on the strap teeth 3 of the strap 1, thus ensuring the stability and security of the lock. After the size adjustment and locking are completed, the excess strap 1 at the end can be cut off with scissors, leaving the loop portion to work with the foreskin fixing ring for foreskin fixation. When it is necessary to remove the cable ties, the safety buckle 4 and the locking ring 2 can be cut directly with scissors to break their structure and unlock them. The teeth 3, the first buckle tooth 21, and the second buckle tooth 41 all adopt a mature one-way movable locking tooth structure, that is, when moving forward, they can slide by relying on the inclined surface of the teeth, and when moving in the opposite direction, they will be locked by the vertical surface of the teeth.

[0020] As an improved specific implementation, one side of the safety buckle 4 has a thickened outer wall 42 that facilitates the operator to apply force.

[0021] like Figure 1 , 2As shown in Figure 3, when the safety buckle 4 is installed on the belt body 1, the thickened outer wall 42 faces outward, which increases the surface volume of the safety buckle 4, making it easier for the doctor to press on it for operation, and making it easier to apply force to slide the retaining ring 2 and the belt body 1, or to apply force to slide the safety buckle 4 and the belt body 1.

[0022] As an improved specific implementation, the safety buckle 4 has a second extension strip 43 on one side to facilitate the operator to apply force.

[0023] like Figure 3 As shown, in specific implementation, the newly added second extension strip 43 extends outward, providing a larger position for the doctor to operate the safety buckle 4. The doctor can use the thumb and forefinger to hold the second extension strip 43 to slide the safety buckle 4, thereby improving the convenience of operation. After the adjustment of the safety buckle 4 is completed, the second extension strip 43 can be cut off from the base with scissors without affecting the state of the bandage itself in fixing the foreskin in a ring.

[0024] As an improved specific implementation, the outer side of the retaining ring 2 is provided with a first extension strip 22 to facilitate the operator to apply force.

[0025] like Figure 1 , 2 As shown in Figure 3, in specific implementation, the newly added first extension strip 22 extends outward, providing a larger position for the doctor to operate the retaining ring 2. The doctor can use the thumb and forefinger to grasp the first extension strip 22 to slide the retaining ring 2, thereby improving the convenience of operation. After the retaining ring 2 is adjusted, the first extension strip 22 can be cut off from the root with scissors without affecting the state of the bandage itself in fixing the foreskin in a ring.

[0026] As an improved specific implementation, the distal end of the first extension strip 22 has an enlarged protrusion 23.

[0027] like Figure 1 , 2 As shown in Figure 3, the protrusion 23 increases the volume of the end of the first extension strip 22, making it easier for the doctor to press his / her fingers on it for operation, and making it easier to apply force to slide the retaining ring 2 and the belt body 1, thus preventing the strip-shaped first extension strip 22 from slipping.

[0028] As an improved specific implementation, a blocking piece 5 is provided on the end of the belt body 1 where the retaining ring 2 is located. When the open end of the belt body 1 passes through the retaining ring 2 and is wound into a ring, the blocking piece 5 together with the inner side of the belt body 1 surrounds and forms an annular inner wall.

[0029] like Figure 1 , 2As shown in Figure 3, the belt 1 itself is wound into a ring to hold the foreskin. Then, the intersection of the winding will produce a non-smooth angle. By further setting the blocking piece 5 to extend along the intersection, a smooth transition is achieved, avoiding the angle at the intersection, thus making the ring limit force of the foreskin uniform, avoiding uneven force on the foreskin at a certain point, which would affect the positioning deviation and the deviation of the cutting position.

[0030] As an improved specific implementation, the thickness of the blocking sheet 5 gradually decreases as it extends outward.

[0031] like Figure 1 , 2 As shown in Figure 3, the distal end of the blocking piece 5 gradually becomes thinner, allowing the blocking piece 5 to bend more flexibly and fit into the interior of the contacted belt 1, and the distal end can transition into the belt 1 more smoothly.

[0032] As an improved specific implementation, the size of the belt body 1 gradually decreases towards the open end where the belt teeth 3 are located, thereby facilitating the open end of the belt body 1 to pass through the retaining ring 2 and allow the belt teeth 3 to reach the retaining ring 2.

[0033] like Figure 1 , 2 As shown in Figure 3, the open end of the belt body 1 is smaller in size, making it easier to pass through the retaining ring 2 and pull until the belt teeth 3 reach the retaining ring 2 for engagement, thus improving operational convenience.

[0034] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
