[0006] To solve the above-mentioned technical problems, the technical scheme adopted by the utility model is as follows:

[0007] The application relates to an alcohol lamp auxiliary device, which comprises a cover body sleeved on the outside of an alcohol lamp, at least one inlet is arranged on the cover body, a guide plate is arranged at each inlet, the cover body is rotationally connected with the guide plate, the height difference between the rotation of the guide plate and the cover body and the outer flame of the alcohol lamp is 3-5 cm, a fixing device for fixing a needle tool is arranged on the guide plate, the fixing device comprises an elastic fixing block, a fixing groove matched with the needle tool is arranged on the elastic fixing block, and the fixing groove is an open groove.

[0008] After the technical scheme is adopted, the cover body is sleeved on the outside of the alcohol lamp, the flame of the alcohol lamp can be protected, the flame of the alcohol lamp is prevented from swinging under the influence of laminar flow or wind, the needle tool can be stably contacted and heated by the outer flame of the alcohol lamp for disinfection, the guide plate can rotate relative to the cover body, the rotation friction between the guide plate and the cover body is large, the guide plate and the cover body can be fixed at a certain angle through the friction after the guide plate and the cover body form the certain angle, and the angle adjusting mode is simple. When the needle tool is fixed on the guide plate through the fixing groove (the needle tool and the fixing groove are also clamped through the friction), the needle tool can be contacted with the outer flame of the alcohol lamp at the angle, the heating and disinfection effect of the needle tool is improved, the heating time is reduced, when the heating and disinfection are completed, the heated needle tool can be directly taken out in the direction of vertically and remotely from the cover body through the inlet on the cover body, the possibility of pollution of the heated part is reduced, and the safety of hemostasis is improved. The needle tool is relatively light, and the angle between the guide plate and the cover body is not changed due to the gravity of the needle tool after the needle tool is placed on the guide plate and fixed. Therefore, the angle between the guide plate and the cover body is not changed after the angle between the guide plate and the cover body is fixed through the friction, and the guide plate is stable during use.

[0009] The application does not need a doctor to hold the needle tool for heating, the heated needle tool can be taken out through the inlet, the operation is relatively convenient, the use feeling of the device is improved, the device can also adjust the contact angle between the needle tool and the outer flame according to different types of needle tools, so that the heating time is reduced and the heating effect is improved. Meanwhile, the device can also change the size of the guide plate, so that the guide plate can be matched with other non-needle instruments for heating and disinfection, and the practicability of the device is improved. In addition, the guide plate in the device is arranged on the cover body, when the guide plate and the cover body are not rotated, the guide plate and the cover body are integrally formed, the structure is relatively simple, and the device is convenient to store.

[0010] The cover body is connected with an angle supporting device, the angle supporting device comprises a bottom plate arranged on the outer wall of the cover body, at least one telescopic rod is connected with the bottom plate, and a supporting plate is connected with the telescopic rod.

[0011] With this technical solution, when the guide plate rotates to a certain angle relative to the cover, the support plate on the telescopic rod can be stretched to support the guide plate, which is already at a certain angle relative to the cover, thereby achieving the purpose of fixing and limiting the position of the guide plate. At the same time, this device adds an angle support device, allowing the guide plate to adjust its angle with the cover without friction. This angle adjustment method is more stable and can improve the stability of the device during use.

[0017] By adopting this technical solution, the sliding groove increases the smoothness of the elastic fixing block's adjustment on the guide plate. The baffle cooperates with the sliding groove to limit the elastic fixing block, achieving the effect of fixing and adjusting the elastic fixing block. The fixing between the elastic fixing block and the sliding groove relies on the friction of the elastic fixing block in the sliding groove for positioning. This positioning method is simple and convenient to operate.

[0018] The fixing groove is provided with a first opening, the width of which is 1 / 2 to 4 / 5 of the needle diameter arc length, and the fixing groove is interference-fitted with the needle.

[0019] By adopting the technical scheme, the first opening is arranged, so that the needle tool can be clamped in the fixed groove through the interference fit of the shape and the fixed groove, and the needle tool can be taken out from the cover after being heated through the first opening and the inlet, thereby facilitating subsequent operation, and the clamping mode is simple and convenient to operate.

[0020] In summary, due to adoption of the above technical scheme, the beneficial effects of the utility model are:

The elastic fixing block 6 is provided with a fixing groove 701 matched with the thimble. The fixing groove 701 is an open groove.

[0036] In the embodiment, the cover body 4 is annular structure, and the size of the cover body 4 is matched with the maximum diameter of the alcohol lamp, so that when the cover body 4 covers the outside of the alcohol lamp, the alcohol lamp is directly at the center position of the cover body 4. In other embodiments, the cover body 4 can also be directly arranged to be matched with the shape of the alcohol lamp, so that the position of the alcohol lamp in the cover body 4 is more accurate, or the diameter of the cover body 4 is smaller than the maximum diameter of the alcohol lamp, so that the cover body 4 is sleeved on the upper part of the alcohol lamp. This structure is simpler, and the consumption of the cover body 4 material is reduced.

[0037] In the embodiment, the cover body 4 and the guide plate 5 are made of stainless steel material. The stainless steel material is corrosion resistant, and the thermal conductivity coefficient is low. Before use, the cover body 4 and the guide plate 5 can be sterilized by high-temperature steam, and the sterilization effect is good. In order to further prevent the heat conduction of the stainless steel, in other embodiments, heat-resistant paint which will not change in nature under heat can be coated on the inner side wall of the cover body 4. In the embodiment, only the end of the needle with a sharp part contacts the outer flame of the alcohol lamp, so the heat will not be transmitted to the non-heating end of the needle through the guide plate 5, and the heat will only be transmitted from the heating end to the non-heating end of the needle.

[0038] In the embodiment, the needle can be any one of a suture needle and an acupuncture needle. In the application, a large-head needle 8 which is used in ophthalmic surgery is taken as an example.

When the pin is fixed on the guide plate 5 through the fixing groove 701 (the pin and the fixing groove 701 are also clamped through friction), the pin can be contacted with the outer flame of the alcohol lamp at this angle, which improves the heating and disinfection effect of the pin and reduces the heating time. When the heating and disinfection are finished, the pin after being heated can be taken out in a direction perpendicular to and away from the cover 4 through the inlet on the cover 4, which reduces the possibility of pollution of the heated part and improves the safety of hemostasis.

[0047] The present application does not need to be held by the doctor to heat the pin, and the pin after being heated can be taken out through the inlet, which is more convenient to operate, increases the use of the device, and the device can also adjust the contact angle of the pin and the outer flame according to different types of pins to reduce the heating time and improve the heating effect.
