Description

Technical Field

[0001] The utility model relates to the technical field of surgical electrocautery, in particular to a device for removing scale from a surgical electrocautery head. Background Art

[0002] Surgical operations require the application of a high-frequency electrocautery, which heats tissues by generating a high-frequency high-voltage current at the tip of an effective electrode when it comes into contact with the body, achieving the separation and coagulation of body tissues, thereby serving the purpose of cutting and hemostasis. However, during the application process, the blood scale formed after blood coagulation often adheres to the electrocautery head, affecting the use efficiency of the electrocautery.

[0003] The commonly adopted method is usually to configure a friction-type blood scale removal patch to remove the blood scale. Due to problems in the force applied during manual wiping, the cleaning process is difficult and the blood scale is difficult to be completely removed. In addition, the removed blood scale is scattered, easily causing mess on the operating table. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for removing scale from a surgical electrocautery head.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A device for removing scale from a surgical electrocautery head includes a first box body. The upper part of the first box body is open. On both left and right sides of the opening at the upper part of the first box body, abrasive plates are installed. There is a gap between the left and right abrasive plates for the vertical movement of the electrocautery. Removable abrasive layers are connected to the opposite sides of the two abrasive plates. At the top of the abrasive plates, a second box body is installed. On both left and right sides of the second box body, wave blocks are installed. A guiding through groove communicating with the first box body is opened on the second box body, and the guiding through groove is located between the two wave blocks.

[0007] As a preferred solution, the abrasive layer is fixed on the abrasive plate through a locking member. The locking member includes a first U-shaped clamping block and a second U-shaped clamping block. On the opposite inner sides of the first U-shaped clamping block, first grooves are opened. On the opposite inner sides of the two first grooves, first teeth are installed. On the opposite outer sides of the first U-shaped clamping block, second grooves are opened. On the opposite outer sides of the two second grooves, second teeth cooperating with the first teeth are installed.

[0008] As a preferred solution, a plurality of first teeth and second teeth are provided. Each first tooth is welded on the first U-shaped clamping block, and each second tooth is welded on the second U-shaped clamping block.

[0009] As a preferred solution, the second box body has a cavity, and two arc-shaped scraping plates for centering and clamping are arranged inside the cavity. The two arc-shaped scraping plates are located on the left and right sides of the guiding through groove. The bottom of the arc-shaped scraping plate is hinged to the bottom of the cavity. A first connecting piece, a second connecting piece and a third connecting piece for pushing the arc-shaped scraping plate to rotate are arranged in the cavity. One end of the first connecting piece and one end of the second connecting piece are hinged to one end of the third connecting piece. The other end of the first connecting piece is hinged to the top of the cavity. The other end of the second connecting piece is hinged to the middle of the arc-shaped scraping plate. An internally threaded sleeve is hinged to the other end of the third connecting piece. A threaded rod that is threadedly engaged with the internally threaded sleeve is installed in the internally threaded sleeve. The other end of the threaded rod horizontally penetrates through the side surface of the second box body.

[0010] As a preferred solution, a hand wheel is installed at one end of the threaded rod that penetrates through the second box body, and a bearing seat is installed at the other end of the threaded rod. The bearing seat is fixed to the bottom of the cavity.

[0011] As a preferred solution, a sliding groove is horizontally opened on the side surface of the first box body. A drawer that can slide in and out is installed in the sliding groove. The drawer is used to hold the blood scale debris after the electrosurgical knife hangs and picks up the electrosurgical knife. The position of the drawer after being inserted into the sliding groove is directly below the gap between the left and right two grinding plates.

[0012] As a preferred solution, four U-shaped parts distributed in a matrix are arranged between the second box body and the grinding plate, and between the grinding plate and the first box body.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1). In order to better remove the debris attached to the surgical electrosurgical knife, the subsequent surgical electrosurgical knife moves back and forth on the wave block. When the handle of the surgical electrosurgical knife is horizontally pushed by the wave block, the knife body fluctuates up and down to achieve height change and slide left and right at the same time. Then, it is ensured that the knife body part of the surgical electrosurgical knife moves up and down and left and right between the two grinding layers, and the debris on the surgical electrosurgical knife is thoroughly wiped and collected.

[0015] 2). A locking part is designed to realize the detachable of the grinding layer on the grinding plate. The locking part itself applies an up-and-down force by two U-shaped clamping blocks to quickly clamp the grinding layer and the grinding plate; when disassembling, apply a left-and-right force to the two U-shaped clamping blocks to separate them, and the grinding layer can be replaced.

[0016] 3). In order to further wipe the surgical electrosurgical knife, two arc-shaped scraping plates are installed in the second box body. Subsequently, by simply rotating the left and right hand wheels respectively, the distance between the two arc-shaped scraping plates inside the second box body can be adjusted to facilitate better wiping of the debris on the surgical electrosurgical knife.

Specific embodiments

[0021] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0022] Refer to Figure 1-Figure 3 , the present invention provides a technical solution:

[0023] A scale removal device for a surgical electrocautery head includes a first box body 1 with an opening at the upper part. On both left and right sides of the opening at the upper part of the first box body 1, frosted plates 4 are installed. There is a gap for the vertical movement of the electrocautery between the left and right frosted plates 4. Frosted layers 7 are detachably connected to the opposite side surfaces of the two frosted plates 4. A second box body 8 is installed on the top of the frosted plate 4. Wave blocks 9 are installed on both left and right sides of the second box body 8. A guiding through groove 10 communicating with the first box body 1 is opened on the second box body 8, and the guiding through groove 10 is located between the two wave blocks 9.

[0024] In the above structure, the first box body 1 is provided to accommodate the debris wiped by the surgical electrotome. Subsequently, the debris enters the interior of the first box body 1 from the opening above the first box body 1. Two frosted plates 4 are designed and installed on the left and right sides of the top of the first box body 1. During the subsequent up and down sliding of the surgical electrotome, the handle part of the electrotome is placed in the gap between the two frosted plates 4. Friction is generated between the two side surfaces of the surgical electrotome and the left and right frosted plates 4, and then the surface of the surgical electrotome is wiped. In order to increase the frictional force at this place, frosted layers 7 are selected to be installed on the opposite side surfaces of the two frosted plates 4, and the frosted layers 7 are selected to be installed on the frosted plates 4 in a detachable connection manner. In order to drive the overall up and down movement of the surgical electrotome, a second box body 8 is selected to be installed on the frosted plate 4, and a wave block 9 is also installed on the second box body 8. Subsequently, the surgical electrotome is inserted into the gap between the two frosted layers 7 through the guiding through groove 10. As the surgical electrotome is pushed horizontally and moves in the guiding through groove 10, the handle part of the surgical electrotome起伏上下 along the wave block 9, the height can be changed, and it can also slide left and right, thereby ensuring that the blade part of the surgical electrotome moves up and down and left and right between the two frosted layers 7, and finally completing the debris wiping work and debris collection work of the surgical electrotome.

[0025] For the above-mentioned frosted layer 7, a detachable connection to the frosted plate 4 is selected, and the following specific detachable connection structure is designed:

[0026] The frosted layer 7 is fixed on the frosted plate 4 through a locking member 5. The locking member 5 includes a first C-shaped block 51 and a second C-shaped block 52. On the opposite inner side surfaces of the first C-shaped block 51, first grooves 511 are opened. On the opposite inner side surfaces of the two first grooves 511, first teeth 512 are installed. On the opposite outer side surfaces of the first C-shaped block 51, second grooves 521 are opened. On the opposite outer side surfaces of the two second grooves 521, second teeth 522 that cooperate with the first teeth 512 are installed.

[0027] Subsequently, the first U-shaped clamping block 51 can be docked with the second U-shaped clamping block 52. If it is selected that the first teeth 512 and the second teeth 522 fit each other at the docking position, the first U-shaped clamping block 51 and the second U-shaped clamping block 52 can be used in cooperation to lock the frosting layer 7 on the frosting plate 4. In order to ensure that the side surface at the mating position of the first U-shaped clamping block 51 and the second U-shaped clamping block 52 is not uneven, two grooves are provided on the clamping block at the docking position. Subsequently, the clamping block is installed in the corresponding groove. During installation, only the first U-shaped clamping block 51 and the second U-shaped clamping block 52 need to be buckled up and down with each other. In fact, the second teeth 522 that cooperate with the first teeth 512 are meshed with each other to complete the locking work of the two. When disassembling, only the first U-shaped clamping block 51 and the second U-shaped clamping block 52 need to be错开 left and right to separate the two from each other, and then the frosting layer 7 can be removed and a new frosting layer 7 can be replaced. The overall fixing and disassembly are relatively convenient. In addition, in some other embodiments, the two can also be fixed by the existing connection method of male and female buckles. For example, male buckles are installed on the top surface and the ground surface of the frosting plate 4 respectively, and female buckles that cooperate with the male buckles are installed at both ends of the frosting layer 7, and the same effect can be achieved.

[0028] In order to better connect the corresponding teeth to the corresponding clamping blocks, the following specific connection structure is designed for the two: A plurality of first teeth 512 and second teeth 522 are provided. Each first tooth 512 is welded to the first U-shaped clamping block 51, and each second tooth 522 is welded to the second U-shaped clamping block 52.

[0029] In order to further wipe the surgical electrocautery knife, the following structure is also designed:

[0030] The second box body 8 has a cavity 82. Two arc-shaped scraping plates 14 for centering and clamping are arranged inside the cavity 82. The two arc-shaped scraping plates 14 are located on the left and right sides of the guiding through groove 10. The bottom of the arc-shaped scraping plate 14 is hinged to the bottom of the cavity 82 of the cavity 82. A first connecting piece 11, a second connecting piece 12 and a third connecting piece 13 for pushing the arc-shaped scraping plate 14 to rotate are arranged in the cavity 82. One end of the first connecting piece 11 and one end of the second connecting piece 12 are hinged to one end of the third connecting piece 13. The other end of the first connecting piece 11 is hinged to the top of the cavity 82. The other end of the second connecting piece 12 is hinged to the middle of the arc-shaped scraping plate 14. The other end of the third connecting piece 13 is hinged with an internal thread sleeve 17. A threaded rod 16 that is threadedly matched with it is installed in the internal thread sleeve 17. The other end of the threaded rod 16 horizontally penetrates through the side surface of the second box body 8.

[0031] When in use, the threaded rod 16 is rotated in the second box body 8, and the internal threaded sleeve 17 is displaced left and right on the threaded rod 16, so as to cause the first connecting piece 11, the second connecting piece 12 and the third connecting piece 13 to rotate the arc scraper 14 itself around the hinge point between the arc scraper 14 and the cavity bottom; when the internal threaded sleeve 17 moves to the left, the arc scraper 14 rotates counterclockwise; on the contrary, when the internal threaded sleeve 17 moves to the right, the arc scraper 14 rotates clockwise;

[0032] The same structure is installed on both sides of the second box body 8, and the gap between the left and right arc scrapers 14 is adjusted subsequently. Similarly, when the surgical electrosurgical knife moves vertically and horizontally in the guide groove 10, the left and right arc scrapers 14 scrape off the debris on the surface of the knife body, and the debris falls to the frosted layer 7 through the lower channel of the guide groove 10 and flows into the first box body 1 through the gap between the frosted layers 7.

[0033] In order to more conveniently rotate the threaded rod 16, a handwheel 18 for driving the threaded rod 16 to rotate in the cavity 82 is installed at one end of the threaded rod 16 that passes through the outside of the second box body 8, and a bearing seat 15 for supporting the threaded rod 16 itself is installed at the other end of the threaded rod 16. The bearing seat 15 is fixed to the bottom of the cavity 82. The threaded rod 16 can be driven to rotate by turning the handwheel 18 subsequently, and the bearing seat 15 installed at the other end plays a supporting role for the threaded rod 16.

[0034] Finally, in order to facilitate the removal of the debris in the first box body 1, a slide groove is designed to be horizontally opened on the side of the first box body 1, and a drawer 2 that can slide inwards and outwards is installed in the slide groove. The drawer 2 is used to hold the blood, scale and debris after the electric knife is hung and removed. After the drawer 2 is inserted into the slide groove, the position is directly below the gap between the left and right sanding plates 4.

[0035] Subsequently, the drawer 2 only needs to be pulled out from the slide slot to dump the debris in the drawer 2 to a designated position, and then the drawer 2 can be inserted into the slide slot again to continue the left collection work.

[0036] Finally, in order to have a certain space gap between the second box body 8, the frosting plate 4 and the first box body 1, four U-shaped pieces 3 distributed in a matrix are selected to be provided between the second box body 8 and the frosting plate 4, and between the frosting plate 4 and the first box body 1.

[0037] The U-shaped member 3 between the second box body 8 and the frosting plate 4 is fixed up and down by welding. Similarly, the U-shaped member 3 between the frosting plate 4 and the first box body 1 can be fixed by the same welding method.
