Description

Technical Field

[0001] This application relates to the field of medical surgical instrument technology, specifically to an electrosurgical blade for anal canal treatment. Background Technology

[0002] Genital warts can appear on the skin of the anus, anal canal, or perineum. In the early stages, they may appear as small, light red, dark red, or dirty gray nipple-like protrusions with a granular or rough surface, resembling the head of a pin or the stamen of a flower. They gradually increase in number and size and may merge into patches or overlap each other.

[0003] Electrosurgical treatment is suitable for condyloma acuminata that is large, numerous, has a wide base, or is located deep within the anal canal. However, when using an electrosurgical knife to treat condyloma acuminata inside the anal canal, the limited length of the electrosurgical tip prevents it from penetrating deep into the anal canal to remove the condyloma acuminata, thus affecting the treatment area. Utility Model Content

[0004] In order to remove condyloma acuminata deep in the anal canal and improve the removal effect of the electrosurgical head on condyloma acuminata, this application provides an electrosurgical head for anal canal treatment.

[0005] An electrosurgical blade for anal canal treatment includes: a blade shaft, which includes a connecting section that can be electrically connected to the handle of the electrosurgical blade and a conductive section wrapped with an insulating sleeve; a working part fixedly connected to the conductive section, the working part being hook-shaped, the inner side of the working part being provided with a hooking surface having a hooking function, and the outer side of the working part being provided with a scraping part having a scraping function, the thickness of the scraping part gradually decreasing along the direction from the inner side of the working part to the outer side.

[0006] In one embodiment of this application, the working part includes a working section one parallel to the axis of the tool holder and a working section two connected to the working section one and being arc-shaped.

[0007] In one embodiment of this application, a shovel is provided on the outer side of working section one and / or the outer side of working section two.

[0008] In one embodiment of this application, along the axial direction of the working part, the working part includes a first section parallel to the axial direction of the tool holder and a second section perpendicular to the first section.

[0009] In one embodiment of this application, a shovel portion is provided on the outer side of the first section and / or the outer side of the second section.

[0010] In one embodiment of this application, the outer wall of the insulating sleeve is provided with length markings along the axial direction of the tool holder.

[0011] In one embodiment of this application, the outer wall of the conductive segment is provided with reinforcing ribs.

[0012] In one embodiment of this application, the projected length of the working part located outside the insulating sleeve along the axial direction of the tool holder is 2 to 5 mm.

[0013] In one embodiment of this application, the length of the conductive segment is 7 to 9 cm.

[0014] In one embodiment of this application, the electrosurgical head for anal canal treatment further includes a rubber sleeve that can be fitted onto the handle of the electrosurgical head, and the rubber sleeve is fixedly connected to an insulating sleeve.

[0015] The beneficial effects of this application are at least as follows:

[0016] After the blade is inserted into the electrosurgical handle and energized, the blade, working part, and scraper part become electrified, allowing for the cutting of condyloma acuminata. When cutting smaller condyloma acuminata, the hook surface on the inner side of the working part can be used to surround and cut the wart. When the condyloma acuminata is larger, the outer scraper part can be energized and scraped away. Therefore, depending on the size of the condyloma acuminata, either the hook surface on the inner side of the working part or the scraper part on the outer side can be used for removal. This electrosurgical head significantly improves the efficiency and effectiveness of condyloma acuminata removal. Attached Figure Description

[0030] To provide a clearer understanding of the technical features, objectives, and effects of this application, specific embodiments of this application are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0031] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0032] To keep the drawings concise, only the parts relevant to this application are shown schematically in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0033] The "fixed connection" between the two components in this application is achieved through methods such as integral manufacturing, threaded connection, snap welding, and bonding, so that the relative position between the two components does not change or rotate relative to each other during use.

[0034] Please see Figures 1 to 6 Learn more about this application.

[0035] See Figure 1 An electrosurgical blade for anal canal treatment includes a working part 201, a blade 101, and an insulating sleeve 301 fitted onto the blade 101. See also... Figures 2 to 4 The cutter bar 101, the working part 201, and the shovel part 203 can be made of highly conductive materials such as stainless steel and tungsten alloy.

[0036] See Figure 2Along the axial direction of the tool holder 101, the tool holder 101 includes a connecting section 102 and a conductive section 103. One end of the conductive section 103 is connected to the connecting section 102, and the other end is connected to the working part 201. The connecting section 102, the conductive section 103, and the working part 201 can be manufactured by an integrated manufacturing process, or they can be produced by welding or other methods to achieve a fixed connection between the connecting section 102, the conductive section 103, and the working part 201.

[0037] See Figure 5 The electrosurgical handle 501 is provided with a connection hole 502. After the connecting section 102 is inserted into the connection hole 502, the metal spring in the connection hole 502 is in direct contact with the connecting section 102. When the operator presses the button on the electrosurgical handle 501, the current in the electrosurgical handle 501 connected to the host flows to the human tissue through the metal spring, the connecting section 102, the conductive section 103, and the working part 201 to achieve the purpose of cutting or coagulation. The current finally returns to the host through the negative electrode plate, thus constructing a complete current circuit.

[0038] Since the length of the anal canal is generally between 3 and 5 centimeters, in one embodiment of this application, the length of the conductive segment 103 is 7 to 9 centimeters, so that the electric knife head has a suitable length to extend into the anal canal, avoiding the electric knife head being too short and unable to penetrate into the anal canal to cut condyloma acuminata, and also preventing the electric knife head from being too long, which would cause inconvenience in operation.

[0039] See Figure 2 In one embodiment of this application, the outer wall of the conductive segment 103 is provided with reinforcing ribs 104 to strengthen the structure of the conductive segment 103, ensuring its structural strength and preventing the conductive segment 103 from becoming too long and thus reducing its bending resistance. See also Figure 2 The outer wall of the conductive section 103 is provided with reinforcing ribs 104 along its axial and circumferential directions. Of course, the reinforcing ribs 104 may also have other extending directions, such as a spiral shape coiled around the outer wall of the conductive section 103, which will not be described in detail here.

[0040] The conductive section 103 is wrapped with an insulating sleeve 301 made of materials such as polytetrafluoroethylene. The insulating sleeve 301 is fixedly connected to the conductive section 103 by heat fusion or other processes. Thus, when the electric knife tip is inserted into the anal canal, the insulating sleeve 301 can prevent the current from coming into contact with human tissue from the conductive section 103, causing uncontrollable cutting, so that cutting or clotting can only occur at the working part 201.

[0041] See Figure 1 , Figure 6In one embodiment of this application, along the axial direction of the blade 101, the outer wall of the insulating sleeve 301 is provided with a length scale 302. Medical personnel can use the length scale 302 to understand the depth and size of the skin lesion, so as to facilitate the next treatment operation.

[0042] See Figure 1 The working part 201 extends from the insulating sleeve 301. When the working part 201 is energized, it has the function of cutting or coagulating human tissue.

[0043] See Figure 1 , Figure 3 The length direction of the working part 201 is parallel to the axis of the tool holder 101; the width direction of the working part 201 is... Figure 3 Describe the direction in the middle, for Figure 3 The left and right directions are as follows: the thickness direction of the working part 201 is perpendicular to the plane where the hook-shaped working part 201 is located.

[0044] See Figure 1 The working part 201 is hook-shaped. The inner side of the working part 201 is provided with a hooking surface 202 with a hooking function, and the outer side of the working part 201 is provided with a shovel part 203 with a shovel function. The thickness of the shovel part 203 gradually decreases along the inner side of the working part 201 towards the outer side, so that the shovel part 203 forms a blade-like structure. Thus, the shovel part 203 can remove skin lesions such as condyloma acuminata when it is powered on.

[0045] When cutting smaller condyloma acuminata, the hook surface 202 on the inner side of the working part 201 can be used to surround the condyloma acuminata and cut it. When the condyloma acuminata is larger, the outer shovel part 203 can be used to remove it after being electrified. Thus, depending on the size of the condyloma acuminata, the hook surface 202 on the inner side of the working part 201 or the shovel part 203 on the outer side can be used to remove the condyloma acuminata. The electrosurgical head of this application can significantly improve the removal efficiency and removal effect of condyloma acuminata.

[0046] Further, see Figure 1 The hooking surface 202 is an arc surface to avoid reducing the hooking and scraping effect of the working part 201 on normal tissue when hooking condyloma acuminata or other skin lesions.

[0047] See Figure 1 , Figure 3In one embodiment of this application, the working part 201 includes a first working section 204 parallel to the axial direction of the cutter bar 101 and a second working section 205 connected to the first working section 204 and being arc-shaped. The first working section 204 can increase the distance between the second working section 205 and the insulating sleeve 301, allowing skin lesions such as condyloma acuminata to more easily enter the hook opening and be hooked by the hooking surface 202, facilitating the cutting of the skin lesions. Since condyloma acuminata in its early stages and small size is circular and elliptical in shape, the arc-shaped second working section 205 can frame the condyloma acuminata along its circumference, and the hooking surface 202, after being energized, can quickly cut the condyloma acuminata.

[0048] See Figure 3 In one embodiment of this application, a shovel portion 203 is provided on the outer side of both working section one 204 and working section two 205, thereby increasing the effective range of the shovel portion 203. When the electrosurgical head is pushed and pulled along the length of working section 201, the shovel portion 203 on working section two 205 is used to cut larger lesions. Since working section two 205 is arc-shaped, the contact area between the shovel portion 203 and the lesion gradually increases, resulting in a gradual increase in cutting length with increasing cutting depth. This progressive cutting length allows medical personnel to observe bleeding and other conditions during cutting and select appropriate next treatment steps based on the cutting situation. When the electrosurgical head is oscillated along the width of working section 201, the shovel portions 203 on working section one 204 and working section two 205 can be used to cut larger lesions, significantly improving cutting efficiency. The addition of shovels 203 on the outer sides of both working section 1 204 and working section 2 205 can significantly improve cutting efficiency and make the cutting method more flexible.

[0049] Of course, the arrangement of the shovel 203 is not limited to the outer side of both the first working section 204 and the second working section 205. It can also be that the shovel 203 is located on the outer side of either the first working section 204 or the second working section 205.

[0050] Those skilled in the art to which this application pertains will understand that the shape of the working section 201 is not limited to the shapes of working segment 204 and working segment 205 mentioned above, but can also be other shapes, for example, see Figure 4 In one embodiment of this application, along the axial direction of the working part 201, the working part 201 includes a first section 206 parallel to the axial direction of the tool holder 101 and a second section 207 perpendicular to the first section 206.

[0051] In one embodiment of this application, a shovel portion 203 is provided on the outer side of the first section 206 and the outer side of the second section 207.

[0052] When cutting along the length of the working section 201, the shovel 203 provided in the second section 207 can be used. Since the second section 207 is perpendicular to the first section 206 and is a straight line, it allows for direct cutting to the maximum length, thus improving cutting efficiency. When cutting along the width of the working section 201, the shovel 203 provided in the first section 206 can be used to cut the skin lesion. The shovel 203 located on the outer side of the first section 206 and the outer side of the second section 207 significantly improves cutting efficiency and provides greater flexibility in cutting methods. During coagulation, the second section 207, due to its straight line nature, has a longer contact length with the wound, allowing it to directly cover a larger area of ​​the wound, thereby improving coagulation efficiency.

[0053] Of course, the arrangement of the shovel part 203 is not limited to the way that the shovel part 203 is provided on the outer side of the first section 206 and the outer side of the second section 207. It can also be that the shovel part 203 is provided on the outer side of the first section 206 or the outer side of the second section 207.

[0054] In one embodiment of this application, the portion of the working part 201 located outside the insulating sleeve 301 has a projected length of 2 to 5 mm in the axial direction of the knife bar 101, which reduces the possibility that the working part 201 may accidentally injure normal tissue in the anal canal due to its excessive length in the axial direction of the knife bar 101.

[0055] join Figure 6 In one embodiment of this application, the electrosurgical head for anal canal treatment further includes a rubber sleeve 401 that can be fitted onto the electrosurgical handle 501. The rubber sleeve 401 is fixedly connected to the insulating sleeve 301 by means of heat fusion or other methods. The rubber sleeve 401 can prevent contaminants such as bodily fluids from entering the connection between the connecting hole 502 and the connecting section 102 in the anal canal, reducing the possibility of contamination inside the electrosurgical handle 501.

[0056] Those skilled in the art to which this application pertains will understand that the electrosurgical tip in this application can be used as a disposable consumable.

[0057] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0058] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of this application and are not intended to limit the scope of protection of this application. All equivalent implementations or modifications made without departing from the spirit of the art of this application, such as combinations, divisions or repetitions of features, should be included within the scope of protection of this application.
