Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a handle of a high-frequency electrocautery instrument. Background Art
[0002] Since the knife head and the handle of the traditional high-frequency electrocautery are mostly fixed by threads, it is laborious and inefficient to disassemble and replace the knife head. To solve this problem, the existing patent CN215425051U discloses a high-frequency surgical electrocautery. By setting up a connecting frame, a clamping rod, a rotating column, a sliding frame and a connecting rod to cooperate with each other, the electrocautery head is fixed inside the connecting frame, replacing the traditional thread fixing method, making the replacement more time-saving and labor-saving, thus improving the efficiency of replacing the electrocautery head, and improving the practicability and convenience of the main body. However, the components used to fix the knife head in this scheme are relatively complex, and each component is arranged inside the connecting frame. Once a certain component is damaged, it will be difficult to repair and replace, which will inevitably lead to poor fixing effect of the electrocautery head. Content of the Utility Model
[0003] Aiming at the deficiencies of the above-mentioned prior art, the utility model provides a handle of a high-frequency electrocautery instrument, which can not only solve the problem of inconvenient disassembly of the electrocautery head, but also has a simpler structure, is easy to replace and repair, and can better ensure the fixing effect of the electrocautery head.
[0004] The utility model realizes the above purpose through the following technical solutions:
[0005] A handle of a high-frequency electrocautery instrument, including a main body, a top cover and a power connection head. A connecting seat is arranged at the upper end of the main body, a knife seat is arranged at the upper end of the connecting seat, and a plurality of clamping pieces are evenly distributed along the circumference on the knife seat. An upper limit platform and a lower limit platform are respectively arranged at the upper and middle parts of the outer side of each clamping piece. A first clamping sleeve is sleeved between the two limit platforms, and a second clamping sleeve is sleeved under the lower limit platform; A through hole is arranged in the top cover, and the top cover is connected to the main body through the connecting seat; The power connection head is inserted into the lower end of the main body.
[0006] Further, the cross section of the clamping piece is fan-shaped.
[0007] Further, the number of the clamping pieces is 2 to 3.
[0008] Further, the connection between the top cover and the connecting seat is a snap connection or a threaded connection.
[0009] Further, both the first clamping sleeve and the second clamping sleeve are silica gel sleeves.
[0010] Compared with the prior art, the advantages and effects of the utility model are:
[0011] 1. The utility model fixes the handle of the electrocautery knife in the form of a collet and a jacket. It can not only conveniently disassemble the tool bit, but also has a simpler internal structure. Moreover, the jacket can be replaced at any time, effectively ensuring a good clamping effect.
[0012] 2. Since the collet for fixing the handle can expand outwards and the jacket is used to limit the expansion of the collet, the range of applicable handle sizes of the utility model is relatively wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further illustrates the utility model in conjunction with embodiments, but the utility model is not limited to these embodiments.
[0021] The handle of a high-frequency electrocautery instrument described in this embodiment, as Figure 1 and 2 shown, includes a main body 1, a top cover 2 and a power connection head 3. A connecting seat 11 is provided at the upper end of the main body 1, and a tool bit seat 12 for installing an electrocautery knife 4 is provided at the upper end of the connecting seat 11. A through hole for the electrocautery knife 4 to be inserted and accommodating the tool bit seat 12 is provided inside the top cover 2. The top cover 2 is sleeved on the connecting seat 11 of the main body 1 by means of snap connection or threaded connection.
[0022] As Figure 2As shown in FIGS. 5, there are 3 sector-shaped clamping pieces 13 evenly distributed along the circumference on the tool holder 12, and there is a certain gap between the clamping pieces 13. The space surrounded by the 3 clamping pieces 13 can allow the handle of the electric scalpel 4 to extend in; in addition, a first-stage limiting platform 14 is provided at the upper part outside each clamping piece 13, and a second-stage limiting platform 15 is provided in the middle outside each clamping piece 13. A first-stage clamping sleeve 5 is sleeved between the two limiting platforms, and a second-stage clamping sleeve 6 is sleeved under the second-stage limiting platform 15. Both clamping sleeves are silicone sleeves, which can gather the 3 clamping pieces 13 towards the center to clamp the electric scalpel 4.
[0023] As Figure 2 and 6 shown, the power connection head 3 is inserted into the lower end of the main body 1 through the connection hole 16 at the bottom of the main body 1. The power connection head 3 can adopt an existing safety sheath type banana plug.
[0024] The working principle of this embodiment is as follows:
[0025] 1. Before installing the electric scalpel 4, first sleeve the top cover 2 on the main body 1, and then insert the handle of the electric scalpel 4 through the through hole at the top of the top cover 2. When passing through the space surrounded by the clamping pieces 13, each clamping piece 13 expands outwards under the extrusion of the handle, and the first-stage clamping sleeve 5 and the second-stage clamping sleeve 6 can gather each clamping piece 13 towards the center to clamp the handle. When the bottom of the handle touches the tool holder 12, the installation is in place. Finally, insert the power connection head 3 into the bottom of the main body 1 to be powered on for use;
[0026] 2. After use, first pull out the power connection head 3, then pull out the electric scalpel 4, and then remove the top cover 2 to clean and disinfect the electric scalpel 4 and the handle respectively. Since both two-stage clamping sleeves are made of silicone material, long-term use and cleaning will inevitably cause the silicone to age and the elasticity to be insufficient, which can be replaced at any time according to actual needs to maintain a good clamping effect.
