Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surgical instrument design, and particularly relates to a continuous scalp clip applicator. BACKGROUND

[0002] In recent years, the number of craniotomy operations in neurosurgery in China is estimated to be hundreds of thousands per year. How to quickly and effectively stop bleeding after cutting the scalp during craniotomy is an important problem. Because the number of scalp blood vessels is large, and the blood vessels are relatively small, it is difficult to stop bleeding by suturing. Electrocautery is often used for relatively large blood vessels, and excessive electrocautery can cause skin margin necrosis and difficulty in wound healing. At present, scalp clips are generally used for bleeding in related operations at home and abroad. The use of this medical device includes two parts: one is the scalp clip, and the other is the scalp clip forceps. When using, the scrub nurse installs the scalp clip on the scalp clip forceps and delivers it to the surgeon, who holds the scalp clip forceps with the scalp clip and clamps the scalp clip on one side of the scalp incision, and then delivers the empty scalp clip forceps to the scrub nurse, who again installs the next scalp clip on the scalp clip forceps and delivers it to the surgeon, and so on, until the scalp margins on both sides of the incision are clamped and pressed by the scalp clips to stop bleeding. Generally, dozens of scalp clips are used for a wound, and the process of installing and delivering dozens of scalp clips by the nurse takes a considerable amount of time, increasing the labor intensity of the nurse and prolonging the operation time. During the process of installing the scalp clips by the nurse, there is a lot of bleeding from the scalp, and the prolonged operation time increases the bleeding of the patient.

[0003] In view of the need for continuous and rapid clamping, some domestic and foreign manufacturers have produced some continuous scalp clip applicators, most of which are gun-shaped or forceps-shaped designs, and the operating principle is to apply force to the holding part to deliver the scalp clip to the front end of the clip magazine, and then to clamp it on the scalp incision after stretching it open. However, in the last stage of the process of pushing out the scalp clip, a lot of force is often needed to stretch the scalp clip open, and even manual maintenance of the stretched state of the scalp clip is needed before the clamping is completed. By comparison, the scalp clip forceps can be locked after stretching the scalp clip, so after multiple clamping, the surgeon's hands are more likely to be tired. And most of the designs will have complex mechanical transmission structures, which not only increase the size, weight and production cost of the instrument, but also reduce the reliability of the instrument. In addition, the scalp clips matched with these clamping devices are generally specially designed to realize the function of the clamping device, so that these special scalp clips and ordinary scalp clip forceps become incompatible, and therefore a special scalp clip forceps needs to be designed separately for use with the clamping device. Therefore, these designs are not very ideal, and at present, the most basic scalp clip forceps are still used for clamping in craniotomy operations at home and abroad. SUMMARY

[0039] Working process:

[0040] The head clamp 7 is sequentially worn on the Y-shaped guide rail 3 in a fixed direction, and is pre-installed in the magazine 2, when in use, the ejection opening 11 of the clamping device is aligned with the head to be clamped, the operation protrusion 54 of the pushing device 5 is pushed forward, the push rod 53 of the pushing device 5 pushes the head clamp 7 forward, when the front end of the head clamp 7 contacts the left and right Y-shaped pieces 4 in the ejection opening 11, the extension protrusions 75 on the two sides of the front end of the head clamp 7 slide the tail ends of the Y-shaped pieces 4 into the front end opening of the head clamp 7, when the curled edge 76 of the head clamp 7 contacts the front end bifurcations of the Y-shaped guide rail 3 and the Y-shaped pieces 4, the three Y-shaped bifurcations are pressed to the head to be clamped at the same time, the first clamp 72 and the second clamp 73 of the head clamp 7 slide upward and downward along the three Y-shaped bifurcations respectively and support the head clamp 7, when the curled edge 76 of the front end of the head clamp 7 slides out of the range of the three Y-shaped pieces 4, the head clamp 7 clamps the head, the clamping device is withdrawn backward to complete the clamping action, at the same time, the pushing device 5 is reset along the reset channel 52, the next clamping can be performed, the supplementary clamp device 6 pushes the head clamp 7 forward, and the above-mentioned actions are repeated to complete continuous clamping, so that the head incision is clamped side by side;

[0041] Specifically:

[0042] The curled edge 76 of the Y-shaped piece 4, the Y-shaped guide rail 3 and the head clamp 7 jointly push out the head clamp 7;

[0043] In the process of pushing the pushing device 5 to push out the head clamp 7, the curled edge 76 slides along the horizontal part of the Y-shaped guide rail 3, the extension protrusions 75 slide the Y-shaped pieces 4 along the sliding groove of the magazine 2, and the first clamp 72 and the second clamp 73 of the head clamp 7 are respectively distributed on the upper and lower sides of the Y-shaped pieces 4;

[0044] When the curled edge 76 of the hair clip 7 slides to the bifurcated part of the Y-shaped sheet 4 and the Y-shaped guide rail 3, the curled edge 76 continues to slide along the bifurcated part and pushes the bifurcated part of the Y-shaped sheet 4 and the Y-shaped guide rail 3 to the middle while the first clip sheet 72 and the second clip sheet 73 are pushed to the two sides respectively.

[0045] After the bifurcated part of the Y-shaped sheet 4 and the Y-shaped guide rail 3 contacts the hair to be clamped, the hair is clamped, the curled edge 76 of the hair clip 7 continues to slide along the slope formed by the bifurcated part to the two sides of the hair, and after the curled edge 76 contacts the hair, the irregular tissue at the incision of the hair is pressed down and continues to slide forward, and the incision of the hair is slid into the first clip sheet 72 and the second clip sheet 73.

[0046] After the curled edge 76 of the hair clip 7 continues to slide to slide out of the bifurcated part of the Y-shaped sheet 4 and the Y-shaped guide rail 3, the first clip sheet 72 and the second clip sheet 73 clamp the hair, the bifurcated part of the Y-shaped sheet 4 returns to the original position, the pushing device 5 continues to be pushed and the shell 1 is moved backward, and the bifurcated part of the Y-shaped guide rail 3 returns to the original position after being pulled out of the auxiliary opening 74.

[0047] During the pushing process of the hair clip 7, the supplementary clip device 6 pushes the remaining hair clip 7 in the cartridge 2 forward by pulling the supplementary clip spring 62, the extension protrusion 75 slides along the sliding groove of the cartridge 2 to the Y-shaped sheet 4, and the first clip sheet 72 and the second clip sheet 73 are distributed on the two sides of the Y-shaped sheet 4 and the Y-shaped guide rail 3.

[0048] The pushing device 5 is pulled backward after being released by the reset spring, the push rod 53 moves backward through the reset channel 52 at the front end of the top of the shell 1 via the hair clip 7 in the cartridge 2, the pushing device 5 stops moving after contacting the limiting protrusion, the pushing device 5 is pressed when the next pushing is prepared, the push rod 53 pushes the first hair clip 7 in the cartridge 2 forward, the push rod 53 pushes the second hair clip 7 in the cartridge 2 backward, and the push rod 53 is inserted between the first hair clip 7 and the second hair clip 7 in the cartridge 2;

[0049] The Y-shaped sheet 4 and the Y-shaped guide rail 3 are used simultaneously in the application, and the following problems are also solved:

[0050] It is known that when the distance of movement is quantified, the smaller the angle of the inclined plane, the smaller the force required to push the object onto the slope, so for the thinner scalp, the force required to use the clipper to clip is smaller. For the existing traditional scalp clipper, it often needs to be clamped to the maximum before clipping, and the force does not change with the thickness of the scalp. And unlike the existing traditional scalp clipper, the clamping process of the scalp clipper is to open the scalp clipper, maintain the open state of the scalp clipper, send the scalp into the opening of the scalp clipper, and release the scalp clipper. The pushing process of the clipper, the scalp is sent into the opening of the clipper, and the scalp clipper is pushed out. The doctor starts to exert force from pushing out the scalp clipper, and the opening is released. There is no pause in between.

[0051] At the same time, the scalp is not a rigid object and has a certain compressibility. When the bifurcated part of the Y-shaped piece 4 and the Y-shaped guide rail 3 clamps the scalp, the scalp will be compressed by a certain amount. Assuming that only the Y-shaped guide rail 3, when the scalp clip 7 is pushed out, the bifurcated part of the Y-shaped guide rail 3 will compress the center part of the scalp in the clamping range, so that the scalp forms a shape similar to a butterfly. When the front end of the scalp clip 7 contacts the scalp, the size of the scalp clip 7 is equal to the thickness of the center part of the scalp in the clamping range, so the two sides of the scalp clip 7 will be stuck by the thicker remaining scalp, resulting in failure of clipping. Similarly, when only the two Y-shaped pieces 4, the scalp clip 7 will be stuck by the middle part of the scalp in the clamping range. Therefore, the Y-shaped piece 4 and the Y-shaped guide rail 3 need to exist at the same time.

[0052] When the bifurcated part of the Y-shaped piece 4 and the Y-shaped guide rail 3 clamps the scalp at the same time, the part of the scalp between the three Y-shaped structures will still be raised, and the hem 76 at the front end of the scalp clip 7 will be pressed down during the pushing process, so that the scalp is smoothly sent into the opening of the scalp clip 7, and the clipping is completed.

[0053] After the scalp clip 7 clamps the scalp, the bifurcated part of the Y-shaped guide rail 3 is still in the opening of the scalp clip 7. If it is directly pulled out, there is a risk of pulling the scalp clip 7 off the scalp, resulting in failure of clipping. Therefore, the pushing device 5 can continue to push forward by a certain distance at this time, so that the bifurcated part of the Y-shaped guide rail 3 is pulled out of the opening of the scalp clip 7, thereby avoiding failure of clipping.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
