Description

Technical Field

[0001] This utility model belongs to the field of auxiliary device technology, specifically relating to a functional clip and its magazine-type push clip device. Background Technology

[0002] In daily life, metal and plastic clips are used in many situations. Depending on the situation, the function of the clips varies, but they all require opening and clamping. For example, in neurosurgical craniotomy, traditional scalp clamps and disposable scalp clips are used to compress the scalp incision and stop bleeding, providing the surgeon with a clear surgical field. During surgery, each scalp clip needs to be manually installed by a nurse, requiring close cooperation between medical staff. After the surgeon makes the incision, they quickly open the disposable scalp clip to compress the incision and stop the bleeding; this is known as the "clamping hemostasis method." To perform the opening and clamping operations, many specialized tools are currently used by surgeons in the medical field, such as hemostatic forceps and dissecting forceps. Most medical tools are currently single and cannot be used continuously, resulting in cumbersome operation. There is a strong demand for new, simpler tools. Therefore, clip pushers have emerged as auxiliary instruments. Clip pushers, as a new tool in the medical field, can be divided into electric and manual types. While push-clamp devices are convenient, efficient, and low-cost, overcoming the shortcomings of traditional tools, they still have some drawbacks. For example, electric push-clamp devices are relatively bulky and inconvenient to operate, and their electrical components pose unpredictable risks. Manual push-clamp devices are laborious and inconvenient for changing hemostatic clips. Typically, opening forceps can only operate on one opening clip at a time, making the loading and unloading process cumbersome and time-consuming. Furthermore, existing push-clamp devices can only be operated with the forehand; when clamping an incision on the same side as the surgeon's, the position must be changed to the opposite side, which is extremely inconvenient, physically demanding for the surgeon, increases the intensity of the surgery, and indirectly affects the success rate.

[0003] Therefore, there is an urgent need for a high-efficiency, low-cost pusher clamp to reduce the difficulty of operation for doctors, shorten the operation time, alleviate patient pain, and improve the success rate of surgery. Utility Model Content

[0026] The clamping ends of the two clamping parts 702 are configured as interlocking serrated structures 704.

[0027] like Figure 1 , Figure 2 As shown, this utility model provides a magazine-type push-clamp device, including a button 1, a housing 2, a guide 3, a push handle 6, a replacement component, and a functional clip 7 as described in any one of claims 1 to 2. The housing 2, guide 3, button 1, and push handle 6 are reusable components, which are assembled together. The functional clip 7, spring plate 8, square spring 9, replacement compartment 4, and tail cover 5 are replaceable components. The guide 3 is fixed to the front end of the housing 2 by screws. The posts 601 on both sides of the push handle 6 are embedded in the grooves 202 of the housing 2 and rotate around the embedded posts 601. The upper end of the push handle 6 is a pushing part 602 that is pushed and connected to the button 1, so that the push handle 6 can slide forward under the push of the button 1. The button 1 is slidably connected to the housing 2. The replacement component is installed inside the housing 2 for inserting and pushing multiple functional clips 7 forward.

[0028] like Figure 1 , Figure 2As shown, the replacement assembly includes a replacement compartment 4, a tail cover 5, a spring plate 8, and a square spring 9. The replacement compartment 4 is detachably installed inside the outer casing 2 and located behind the guide 3. Multiple functional clips 7 are arranged sequentially inside the replacement compartment 4, and a spring plate 8 is installed behind the functional clips 7. A square spring 9 is installed between the spring plate 8 and the tail cover 5. The spring plate 8 is slidably connected to the inside of the replacement compartment 4, and the tail cover 5 is detachably connected to the replacement compartment 4.

[0029] like Figure 6 , Figure 10 As shown, the left and right sides of the rear end of the replacement chamber 4 are provided with barbs 401, which are engaged with the slots 201 provided on the side wall of the outer shell 2. The inner walls of the left and right sides of the replacement chamber 4 are provided with guide ribs 402, which are engaged with the side notches 703 of the functional clip 7. The spring plate 8 has sliding grooves 801 on both sides, which are engaged with the guide ribs 402 of the replacement chamber 4.

[0030] like Figure 6 , Figure 7 As shown, the tail cover 5 is provided with barbs 501 on both the left and right sides of the front end. The barbs 501 are hooked onto the card plates 403 provided on the left and right side walls of the rear end of the replacement chamber 4. The card plates 403 are provided with card cases 404 on the outside.

[0031] The second barb 501 is inserted into the casing 404 and hooked onto the plate 403.

[0032] like Figures 2-4 As shown, the two pillars 102 on both sides of the button 1 are embedded in the elongated grooves 203 provided in the outer shell 2, and can slide back and forth.

[0033] like Figure 5 As shown, there are two guides 3, which are respectively set on the left and right sides of the outer shell 2, and the upper and lower end faces of each guide 3 are inclined surfaces that gradually approach each other from front to back, which are used to gradually open the functional clamp 7.

[0034] like Figure 8 , Figure 3 As shown, the push handle 6 is triangular in shape, with the top corner being the push part 602 and rounded. It is set in the corresponding slot 101 inside the button 1. The push handle 6 has a column 601 at the rear end and a downward protruding sliding part 603 at the front end. The front end of the sliding part 603 is used to push the function clip 7 forward. The rear end of the sliding part 603 is a slope, which can smoothly pass over the function clip 7.

[0035] The functional clips 7 are loaded sequentially from the end of the replacement chamber 4. Inside the replacement chamber 4, there is a guide rib 402 that fits into the side notch 703 of the functional clips 7. At the front end of the replacement chamber 4, there is a protrusion that connects to the outer shell 2 to prevent the functional clips 7 from slipping. After loading, the spring plate 8 has sliding grooves 801 on both sides that cooperate with the guide rib 402 inside the replacement chamber 4 and enter the replacement chamber 4. The square spring 9 is fixed to the end face of the tail cover 5. The square spring 9 enters the replacement chamber 4 and is compressed until the barbs 501 on both sides of the tail cover 5 hook onto the groove of the replacement chamber 4. Under the action of the spring plate 8, the square spring 9, and the tail cover 5, the functional clips 7 are tightly housed in the cavity of the replacement chamber 4. The front end of the loaded replacement chamber 4 is inserted into the end of the outer shell 2 and pushed forward until the barb 401 on the outer side of the end of the replacement chamber 4 is embedded in the slot 201 at the end of the outer shell 2.

[0036] When the functional clip 7 is extended, button 1 slides backward, causing push handle 6 to move backward. During this movement, the lower end of push handle 6 contacts the arc surface of functional clip 7 and slides along the arc surface until it crosses functional clip 7. Then, push button 1 forward, and push handle 6 moves forward under the action of button 1. The functional clip 7 that push handle 6 crosses moves forward under the action of the front end of push handle 6. The opening of the side notch 703 of functional clip 7 continuously widens under the action of guide rib 402 of replacement compartment 4 and the guide, and the affected area enters the front notch 703 of guide 3. Push button 1 to disengage functional clip 7 from guide 3. Functional clip 7 clamps the required affected area under the action of its own restoring force. When pushed forward, subsequent functional clips 7 are pushed forward by spring plate 8 and square spring 9, preparing for the next use. After the functional clip 7 is used, it is replenished. Hold the outer shell 2 and squeeze the barb 401 of replacement compartment 4 with two fingers to completely remove the replacement assembly. Refill the new replacement assembly and continue to use.
