Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a scalp clip installation device. Background Technology

[0002] In modern neurosurgical craniotomies both domestically and internationally, it is routine to temporarily clamp the edges of the scalp incision with scalp clips to prevent marginal bleeding. However, current scalp clip installation procedures have many drawbacks, severely impacting surgical efficiency and progress. Currently, the specific procedure for installing scalp clips into scalp clip forceps involves the operator pinching the clip with the thumb and forefinger of one hand while holding the forceps handle with the other. The prongs of the forceps are then precisely inserted into the narrow groove in the middle of the clip, and the prongs are opened for use. This process is extremely cumbersome, requiring the operator to pinch each clip individually, which significantly limits the efficiency of scalp clip installation. Furthermore, during the entire craniotomy and scalp incision procedure, the scrub nurse hands the scalp clamps with the scalp clips attached to them to the surgeon. After the surgeon uses them, the empty scalp clamps (i.e., the scalp clips at the beak end of the clamps have been clamped to the edge of the scalp incision for hemostasis) are handed back to the scrub nurse. This back-and-forth process of passing the scalp clamps seems simple, but it consumes valuable surgical time to varying degrees. In situations where surgical time is tight, this may have an adverse impact on the overall surgical schedule and may even affect the surgical outcome. Summary of the Invention

[0003] In view of this, in order to solve the above problems, the purpose of the present invention is to provide a scalp clip installation device, including: a base, a clip and a blocking bolt, wherein the clip is detachably connected to the upper end of the base, a blocking hole is provided through the clip, one side of the blocking bolt passes through the blocking hole, the scalp clip is disposed in the clip, and the scalp clip is operablely lowered along the clip onto the base.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "lateral", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] It should be noted that the terms "horizontal" and "vertical" in this invention are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0022] like Figure 1-4 The diagram shows a preferred embodiment of a scalp clip installation device, comprising: a base 1, a magazine 2, and a blocking bolt 3. The magazine 2 is detachably connected to the upper end of the base 1. A blocking hole is provided through the magazine 2. One side of the blocking bolt 3 passes through the blocking hole. The blocking bolt 3 is used to control the descent of the scalp clip 4 inside the magazine 2. When one side of the blocking bolt 3 passes through the blocking hole, it can prevent the scalp clip 4 from falling. When the scalp clip 4 needs to be used, the blocking bolt 3 can be moved to disengage from the magazine 2, and the scalp clip 4 can then fall under its own weight and the action of the gravity bolt. The scalp clip 4 is disposed inside the magazine 2 and can be operably lowered along the magazine 2 onto the base 1.

[0023] Furthermore, in a preferred embodiment, the base 1 includes a base plate 11, a support portion 12, and a snap-fit ​​portion 13 arranged sequentially from bottom to top. The support portion 12 connects the snap-fit ​​portion 13 and the base plate 11. A scalp clamping groove 14 is provided in the middle of the support portion 12. A snap-fit ​​groove 15 is provided at the upper end of the snap-fit ​​portion 13. A drop hole 16 is provided through the bottom wall of the snap-fit ​​groove 15. The drop hole 16 is directly opposite to the scalp clamping groove 14 and communicates with the scalp clamping groove 14.

[0024] Furthermore, as a preferred embodiment, one end of the support portion 12 has an opening, which is V-shaped and communicates with the scalp clamp groove 14.

[0025] Furthermore, as a preferred embodiment, it also includes a return spring 5, which is disposed at the other end of the support portion 12.

[0026] Furthermore, as a preferred embodiment, the magazine 2 includes: a sleeve 21 and a snap-fit ​​plate 22. The sleeve 21 is a hollow cylindrical shape, and a blocking hole is opened on the side wall of the sleeve 21. The lower end of the sleeve 21 is connected to the snap-fit ​​plate 22, and the snap-fit ​​plate 22 is disposed in the slot 15.

[0027] Furthermore, as a preferred embodiment, the center of the snap-fit ​​plate 22 is provided with a through hole equal to the inner diameter of the sleeve 21, and the through hole is directly opposite the drop hole 16.

[0028] Furthermore, in a preferred embodiment, a stop 23 is provided at one end of the latching part 13, and the stop 23 abuts against the latching plate 22. Further, the stop 23 is used to fix the position of the magazine 2 to prevent the magazine 2 from shifting during use and affecting the descent of the scalp clip 4.

[0029] Furthermore, as a preferred embodiment, a guide block 17 is provided inside the opening. One side of the guide block 17 is connected to the inner wall of one side of the opening. The lower end of the guide block 17 is connected to the base plate 11. One end of the guide block 17 has a ramp, and the beak end of the scalp clamp can extend into the scalp clamp groove 14 from the ramp.

[0030] Furthermore, as a preferred embodiment, a scalp clamp removal slide 18 is formed between the other side of the guide block 17 and the inner wall of the other side of the opening, and the scalp clamp can be disengaged from the scalp clamp groove 14 along the scalp clamp removal slide 18.

[0031] Furthermore, as a preferred embodiment, a gravity bolt is also included, which is slidably disposed within the sleeve 21. More specifically, the gravity bolt is preferably a metal weight. During the scalp clip 4's descent along the sleeve 21, the gravity bolt increases the descent force of the scalp clip 4, assisting it in falling smoothly. Especially when there are many scalp clips 4 within the sleeve 21, and the pressure on the bottom scalp clip 4 is greater, the gravity bolt effectively prevents the scalp clip 4 from jamming due to excessive resistance, ensuring that the scalp clip 4 falls stably and smoothly into the scalp clip groove 14 of the base 1.

[0032] The working principle of this invention is as follows: In use, firstly, the magazine 2 is installed in the slot 15 of the base 1 via the snap-fit ​​plate 22, aligning the connecting hole with the falling hole 16. Several scalp clips 4 and a gravity bolt are then placed into the sleeve 21 of the magazine 2. These steps can be completed and sterilized in advance. During the operation, simply open the sterilized package and remove the magazine 2 with the scalp clips 4 and gravity bolt installed for direct use. Then, the base 1 is fixed to the operating edge of the operating table using the base fixing clamp. When the scalp clip 4 needs to be retrieved, the blocking bolt 3 is moved to disengage it from the sleeve 21. At this time, the scalp clip 4 will fall under its own weight and the action of the gravity bolt. The scalp clip 4 at the bottom will fall into the scalp clip groove 14. At this point, medical personnel can hold the scalp clip forceps and insert the beak end of the forceps into the scalp along the slope of the guide block 17. Within the clamping groove 14, medical personnel can precisely insert the beak end of the scalp clamp into the groove in the middle of the scalp clamp 4. By slightly opening the beak end of the scalp clamp, the scalp clamp 4 can be firmly installed on the beak end of the scalp clamp. At this time, the inner wall of the other side of the opening can be moved slightly away from the guide block 17 to increase the distance between the other side of the guide block 17 and the inner wall of the other side of the opening, thereby increasing the horizontal width of the scalp clamp removal slide 18. This makes it easier to remove the beak end of the scalp clamp along with the installed scalp clamp 4 along the scalp clamp removal slide 18. After removal, the upper scalp clamp 4 will fall back into the scalp clamping groove 14. At this time, the inner wall of the other side of the opening will automatically reset under the action of the return spring 5. When medical personnel need to remove the scalp clamp 4, the above removal process can be repeated.

[0033] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
