A split-type skin preparation model suitable for neurosurgery

Abstract

This invention discloses a split-type skin preparation model suitable for neurosurgical procedures, comprising a gripping part, a right-angle plate, and a horizontal plate. The right-angle plate has horizontal and vertical sections, and the horizontal plate has a horizontal section. Reinforcing rings and snap-fit ​​fasteners are installed on the horizontal and vertical sections, respectively. Another reinforcing ring is installed on the horizontal plate, and another snap-fit ​​fastener is installed on the gripping part. The snap-fit ​​fastener on the vertical section passes through the vertical section and assembles with the reinforcing ring on the horizontal plate, thus mounting the horizontal plate onto the vertical section. Similarly, the snap-fit ​​fastener on the gripping part passes through the horizontal section and assembles with the reinforcing ring on the horizontal section, thus mounting the gripping part onto the horizontal section. This invention, through a template-like design, cuts out the area requiring skin preparation, reducing the risk of over- or under-shaving of the patient's hair due to improper operation by medical personnel. Simultaneously, it significantly reduces the technical requirements for skin preparation, standardizing and unifying the skin preparation area.

Description

Technical Field

[0001] This invention relates to nursing aids, and in particular to a split-type skin preparation model suitable for neurosurgical procedures. Background Technology

[0002] Prep surgery refers to the process of shaving hair and cleaning the surgical area before surgery. It is a procedure performed on patients who are scheduled for surgery to clean the surgical area. Shaving is a traditional prep method and remains the mainstream method in many surgeries. For example, in neurosurgery, medical staff need to prep the surgical area on the patient's head by removing hair from that area.

[0003] Neurosurgical shaving typically involves the entire head. However, with the advancement of the field, more and more clinicians are raising differing opinions regarding the advantages of full shaving. They argue that full shaving may cause minor skin abrasions, potentially disrupting the skin's protective barrier and allowing bacteria to invade, thus increasing the risk of postoperative infection. Furthermore, removing all hair can negatively impact a patient's psychological well-being and their ability to resume normal work and life after surgery.

[0004] Studies have shown that localized small-area skin preparation is safe and effective in neurosurgery, without increasing postoperative infection rates or poor wound healing rates. Localized skin preparation not only reduces surgical trauma for patients but also alleviates their psychological burden, enabling them to adapt to society and work more quickly and significantly shortening the time it takes for them to reintegrate into society.

[0005] Currently, in neurosurgery, most patients are unwilling to have all their hair shaved off during skin preparation. Therefore, partial shaving is mostly used. For patients with hemifacial spasm and trigeminal neuralgia, the skin preparation area is usually two finger widths above the ear and three finger widths behind the ear (parallel to the hairline). However, during partial skin preparation, the remaining hair can interfere with the preparation area, and medical staff may also expand or shrink the patient's skin preparation area, resulting in an irregular skin preparation area. Therefore, we need a skin preparation model to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a split-type skin preparation model suitable for neurosurgery, which can indicate the skin preparation area so that medical staff can quickly and accurately perform skin preparation.

[0007] To achieve the above objectives, the present invention provides a split-type skin preparation model suitable for neurosurgical procedures, comprising a gripping part, a right-angle plate, and a horizontal plate. The right-angle plate is provided with a horizontal part and a vertical part, and the horizontal plate is provided with a horizontal plate part.

[0008] A reinforcing ring and a snap-fit ​​buckle are respectively installed on the horizontal and vertical portions. Another reinforcing ring is installed on the horizontal plate, and another snap-fit ​​buckle is installed on the grip portion. The snap-fit ​​buckle installed on the vertical portion passes through the vertical portion and assembles with the reinforcing ring installed on the horizontal plate, so that the horizontal plate is installed on the vertical portion. The snap-fit ​​buckle installed on the grip portion passes through the horizontal portion and assembles with the reinforcing ring installed on the horizontal portion, so that the grip portion is installed on the horizontal portion.

[0009] As a further improvement of the present invention, the horizontal plate portion is parallel to the horizontal portion.

[0010] As a further improvement of the present invention, the horizontal plate and the right-angle plate are made of elastic material.

[0011] As a further improvement of the present invention, a connecting part is provided on the vertical part, and a reinforcing ring is provided on the connecting part. The plug-in buckle on the horizontal plate part is inserted into this reinforcing ring to complete the assembly.

[0012] As a further improvement of the present invention, a horizontal thinning portion and a horizontal thinning portion are respectively provided on the horizontal portion and the horizontal plate portion, and the horizontal thinning portion and the horizontal plate thinning portion are used to reduce the thickness of the corresponding horizontal portion and the horizontal plate portion.

[0013] As a further improvement of the present invention, the plug-in buckle is provided with a buckle protrusion, which passes through the corresponding reinforcing ring and is clamped and assembled with the reinforcing ring.

[0014] As a further improvement of the present invention, the horizontal plate and the horizontal part are respectively the corresponding horizontal bar and horizontal telescopic bar, and the vertical part is the vertical bar. The horizontal bar is provided with a horizontal telescopic groove and a through groove. One end of the through groove is connected to the horizontal telescopic groove and the other end passes through the horizontal bar. A horizontal telescopic plate is installed on the horizontal telescopic bar. One end of the horizontal telescopic plate is inserted into the horizontal telescopic groove and is engaged and slidably assembled with the horizontal telescopic groove. A vertical telescopic groove is provided on the inner side of the vertical bar. The vertical telescopic groove is engaged and slidably assembled with the vertical telescopic plate.

[0015] As a further improvement of the present invention, a horizontal scale plate is provided on the horizontal telescopic plate, and a scale is provided on the horizontal scale plate. The scale corresponds to the end face of the horizontal bar to read the length of the horizontal telescopic plate inserted into the horizontal telescopic groove.

[0016] The vertical telescopic plate is provided with a vertical scale plate, and the scale plate is provided with a scale, which corresponds to the end face of the vertical rod to read the length of the vertical telescopic plate inserted into the vertical telescopic groove.

[0017] As a further improvement of the present invention, different plug-in buckles are installed on the two crossbars respectively, and different reinforcing rings are provided on the vertical bar and the gripping part respectively. The plug-in buckles pass through the corresponding reinforcing rings and are assembled with them to realize the assembly of the crossbar and the vertical bar, and the other crossbar and the gripping part.

[0018] As a further improvement of the present invention, a locking assembly is installed on the horizontal bar and the vertical bar respectively, and a through groove similar to a through slot is provided on the vertical bar; the locking assembly includes a locking shell, a slider, and a locking block, the locking shell is installed on the horizontal bar or the vertical bar, and a locking shell groove is provided inside the locking shell, and one end of the locking block passes through the through slot and is pressed against the horizontal telescopic plate or the vertical telescopic plate;

[0019] The locking block is assembled with one end of the spring plate, and the other end of the spring plate is assembled with the corresponding horizontal or vertical bar. The spring plate is elastic and applies a spring force to the locking block away from the horizontal or vertical telescopic plate. The spring plate is provided with a spring plate inclined surface, which is fitted and slidably assembled with the slider inclined surface. The slider inclined surface is provided on the slider, which is engaged and slidably installed in the locking housing groove. The slider is provided with an operating block that protrudes from the locking housing groove.

[0020] The slider is also provided with a stop groove, which is assembled with one end of a limit pin, and the other end of the limit pin is installed on the locking housing.

[0021] The beneficial effects of this invention are:

[0022] This invention utilizes a template-based design to cut out the area requiring skin preparation, reducing the risk of improper operation by medical staff resulting in too much or too little hair being shaved. Simultaneously, it significantly lowers the skill requirements for skin preparation, standardizing and unifying the preparation area. The invention employs a soft padding material, making the model more easily conform to the patient's scalp and facilitating operation.

[0023] This invention reduces patients' anxiety about appearance by creating a skin preparation model, and standardizes and unifies the skin preparation area, fully adhering to the principle of "people-oriented" and providing patients with more humane services, demonstrating humanistic care.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] Example 1

[0041] See Figures 1-2The split-type skin preparation model of this embodiment includes a gripping part 110, a right-angle plate 120, and a horizontal plate 130. The right-angle plate 120 is provided with a horizontal part 121 and a vertical part 122, and the horizontal plate 130 is provided with a horizontal plate part 131, which is parallel to the horizontal part 121.

[0042] A reinforcing ring 220 and a snap-fit ​​buckle 210 are respectively installed on the horizontal portion 121 and the vertical portion 122. Another reinforcing ring 220 is installed on the horizontal plate 130, and another snap-fit ​​buckle 210 is installed on the grip portion 110. The snap-fit ​​buckle 210 installed on the vertical portion 122 passes through the vertical portion 122 and is assembled with the reinforcing ring 220 installed on the horizontal plate 130, so that the horizontal plate 130 is installed on the vertical portion 122. The snap-fit ​​buckle 210 installed on the grip portion 110 passes through the horizontal portion 121 and is assembled with the reinforcing ring 220 installed on the horizontal portion 121, so that the grip portion 110 is installed on the horizontal portion 121.

[0043] In use, first assemble the grip 110 and the right-angle plate 120. Then, use the vertical part 122 to position it two finger-widths above the patient's ear, that is, the end face of the vertical part 122 is close to the ear to complete the positioning. The area for skin preparation is the area between the right-angle plate 120 and the ear. Then install the horizontal plate 130, and position the horizontal plate part 131 behind the ear to locate the position three finger-widths behind the ear. At this time, the area between the horizontal plate 130 and the right-angle plate 120 is the area for skin preparation.

[0044] In this embodiment, the grip 110, right-angle plate 120, and horizontal plate 130 can be assembled first. The horizontal plate 130 can rotate around the corresponding snap-fit ​​210. During the first positioning, the horizontal plate 130 is rotated 180°. Figure 1 The middle horizontal plate 130 is rotated 180° to the left to avoid interference from the first positioning.

[0045] Preferably, the horizontal plate 130 and the right-angle plate 120 are made of elastic material, and can be bent and fitted onto the scalp during use to further complete the positioning.

[0046] This design is mainly for quick assembly and disassembly of the horizontal plate 130 and the right-angle plate 120. In actual use, due to the different head sizes of each patient and the difference in the distance between the hairline and the back of the ear, a split design is adopted. Different sizes of horizontal plate 130 and right-angle plate 120 can be selected and combined according to different head sizes to meet the needs of each patient. The buckle design is also for quick disassembly.

[0047] Example 2

[0048] See Figures 3-4In order to make the end faces of the horizontal plate 130 and the right-angle plate 120 flush with the scalp for better scalp preparation, this embodiment provides a connecting part 123 on the vertical part 122. A reinforcing ring 220 is installed on the connecting part 123. The plug-in buckle 210 on the horizontal plate part 131 is inserted into the reinforcing ring 220 to complete the assembly.

[0049] Example 3

[0050] See Figures 5-7 In order to enable the horizontal portion 121 and the horizontal plate portion 131 to bend and conform to the scalp, this embodiment also provides a horizontal thinning portion 124 and a horizontal plate thinning portion 132 on the horizontal portion 121 and the horizontal plate portion 131, respectively. The horizontal thinning portion 124 and the horizontal plate thinning portion 132 are used to reduce the thickness of the corresponding horizontal portion 121 and the horizontal plate portion 131 so that they can be bent better.

[0051] Preferably, the plug-in buckle 210 is provided with a buckle protrusion 211, which passes through the corresponding reinforcing ring 220 and is then clamped and assembled with the reinforcing ring 220.

[0052] Example 4

[0053] See Figures 8-11 In embodiments one through three, the horizontal plate 130 and the right-angle plate 120 are all in a non-adjustable state. For different head shapes, only the corresponding horizontal plate 130 and right-angle plate 120 can be replaced. Obviously, this method is not only time-consuming and laborious but also extremely unreasonable. Therefore, this embodiment makes the following improvements:

[0054] The horizontal plate 130 and the horizontal part 121 are replaced with the corresponding horizontal bar 150 and horizontal telescopic bar 140, and the vertical part 122 is replaced with the vertical bar 160. The horizontal bar 150 is provided with a horizontal telescopic groove 151 and a through groove 152. One end of the through groove 152 is connected to the horizontal telescopic groove 151, and the other end passes through the horizontal bar 150. A horizontal telescopic plate 141 is installed on the horizontal telescopic bar 140. A horizontal scale plate 142 is provided on the horizontal telescopic plate 141. The scale plate 142 is provided with graduations. The graduations correspond to the end face of the horizontal bar 150 to read the length of the horizontal telescopic plate 141 inserted into the horizontal telescopic groove 151. One end of the horizontal telescopic plate 141 is inserted into the horizontal telescopic groove 151 and is engaged and slidably assembled with the horizontal telescopic groove 151. In use, the depth of the horizontal telescopic plate 141 inserted into the horizontal telescopic groove 151 can be adjusted as needed, thereby adjusting the length of the corresponding horizontal part 121 and the horizontal plate part 131. This allows for size adjustment as needed without the need to prepare various specifications of horizontal plates 130 and right-angle plates 120 for disassembly and replacement.

[0055] The vertical rod 160 has a vertical telescopic groove on its inner side. The vertical telescopic groove engages with and slides with the vertical telescopic plate 111. The vertical telescopic plate 111 has a vertical scale plate 112 with graduations. The graduations correspond to the end face of the vertical rod 160 to read the length of the vertical telescopic plate 111 inserted into the vertical telescopic groove.

[0056] Two horizontal bars 150 are each equipped with different plug-in buckles 210, and the vertical bar 160 and the grip part 110 are each provided with different reinforcing rings 220. The plug-in buckles 210 pass through the corresponding reinforcing rings 220 and are assembled with them to realize the assembly of the horizontal bar 150 with the vertical bar 160 and the other horizontal bar 150 with the grip part 110.

[0057] Locking assemblies 300 are respectively installed on the horizontal bar 150 and the vertical bar 160. The vertical bar 160 is provided with a through groove similar to the through slot 152. The locking assembly 300 includes a locking shell 310, a slider 320, and a locking block 330. The locking shell 310 is installed on the horizontal bar 150 or the vertical bar 160. The locking shell 310 is provided with a locking shell groove 311. One end of the locking block 330 passes through the through slot 152 and presses against the horizontal telescopic plate 141 or the vertical telescopic plate 111 to lock the horizontal telescopic plate 141 or the vertical telescopic plate 111, thereby preventing the horizontal telescopic plate 141 or the vertical telescopic plate 111 from extending or retracting. The locking block 330 is assembled with one end of a spring plate 331, and the other end of the spring plate 331 is assembled with the corresponding horizontal bar 150 or the vertical bar 160. The spring plate 331 is elastic and applies pressure to the locking block 330 to move away from the horizontal telescopic plate 150 or the vertical bar 160. The elasticity of the 41 or vertical telescopic plate 111; the spring plate 331 is provided with a spring plate inclined surface 3311, the spring plate inclined surface 3311 is in contact with and slidably assembled with the slider inclined surface 321, the slider inclined surface 321 is provided on the slider 320, the slider 320 is engaged and slidably installed in the locking housing groove 311, the slider 320 is provided with an operating block 322, the operating block 322 extends out of the locking housing groove 311, in use, the operating block 322 drives the slider 320 to slide in the locking housing groove 311 to drive the locking block 330 to press against the horizontal telescopic plate 141 or the vertical telescopic plate 111, or to separate from the horizontal telescopic plate 141 or the vertical telescopic plate 111 so that the spring plate 331 drives the locking block 330 to release and separate from the horizontal telescopic plate 141 or the vertical telescopic plate 111, thereby facilitating the sliding adjustment of the horizontal telescopic plate 141 and the vertical telescopic plate 111.

[0058] The slider 320 is also provided with a stop groove 321, which is assembled with one end of the limiting pin 312, and the other end of the limiting pin 312 is installed on the locking housing 310. This design can limit the maximum displacement point of the slider 320 relative to the limiting pin 312, thereby preventing the slider 320 from being pulled out.

[0059] Figure 11 The demonstration shows the initial state. When it is necessary to adjust the extension and retraction of the horizontal telescopic plate 141 and the vertical telescopic plate 111 relative to the horizontal bar 150 and the vertical bar 160, the slider 320 is first slid outward from the locking housing groove 311 by the operating block 322, so that the slider inclined surface 321 separates from the spring plate inclined surface 3311. The spring plate 331 drives the locking block 330 to release and separate from the corresponding horizontal telescopic plate 141 or vertical telescopic plate 111. At this time, the position of the horizontal telescopic plate 141 or vertical telescopic plate 111 is adjusted. The specific extension and retraction amount can be read by the corresponding position of the horizontal scale plate 142 and the end face of the horizontal bar 150, and the corresponding position of the vertical scale plate 112 and the end face of the vertical bar 160. After the adjustment is completed, the slider 320 is pushed back so that the slider inclined surface 321 and the spring plate inclined surface 3311 are pressed together, thereby driving the locking block 330 to return to pressing on the horizontal telescopic plate 141 or vertical telescopic plate 111 to complete the locking. This design only requires one model to flexibly adapt to different head shapes, thus eliminating the need to prepare numerous models of the Horizontal Plate 130 and Right Angle Plate 120, and also eliminating the need for frequent disassembly and assembly of the Horizontal Plate 130 and Right Angle Plate 120, which greatly facilitates use and improves the range of adaptability.

[0060] Any aspects of this invention not described in detail are well-known to those skilled in the art.

[0061] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
