Description

Technical Field

[0001] The invention belongs to the technical field of electrocoagulation forceps, in particular to an electrocoagulation forceps for plastic surgery. Background Art

[0002] Bipolar electrocoagulation forceps is a new type of surgical instrument commonly used in cosmetic surgery. It uses the thermal effect of high-frequency current to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and fuse the blood vessel and the blood clot into one, thereby achieving effective hemostasis. Bipolar electrocoagulation forceps is favored by minimally invasive surgery clinicians for its simple operation, fast coagulation and good effect.

[0003] However, when the electrocoagulation forceps are manufactured, the connecting tube for positioning the forceps head is of fixed length. In different scenarios, when blood is coagulated on small incisions, an overly long connecting tube will cause the forceps head to be unstable in operation, and when the connecting tube is too long, it is easy to break when it is directly stored.

[0004] In view of this, an electrocoagulation forceps for plastic surgery is proposed. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In view of the following technical problems in the prior art: when the electrocoagulation forceps are manufactured, the connecting tube for positioning the forceps head is of a fixed length. In different scenarios, when performing blood coagulation on small openings, an overly long connecting tube will cause the operation of the forceps head to be unstable, and when the connecting tube is long, it is easy to break when it is directly stored.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an electrocoagulation forceps for plastic surgery, comprising an operating frame, an electrode head and a forceps head; the tail end of the operating frame is connected to an electrode wire, the end of the electrode wire away from the operating frame is connected to the electrode head, and the bottom end of the operating frame is provided with a fixed handle; a movable cavity is opened in the operating frame, a movable rotating shaft, a winding disk and a positioning rotating shaft are rotatably connected in the movable cavity, a movable handle is provided on the outside of the movable rotating shaft, a connecting tube is provided at the tip of the operating frame, the end of the connecting tube away from the operating frame is movably connected to a telescopic sleeve, and the forceps head is hinged at the tip of the telescopic sleeve.

[0008] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a linkage frame and a linkage rod are arranged on the outer side of the positioning rotating shaft. One side of the movable rotating shaft and the linkage rod are mutually driven by a traction wire. A fixing plate penetrates through the inner edge of the movable cavity. A positioning plate is arranged on the outer side of the traction wire close to the fixing plate. A first spring is arranged between the positioning plate and the fixing plate. When the movable rotating shaft is pulled to rotate, the traction wire can pull the linkage rod to rotate. And under the action of the first spring, the movable rotating shaft can be reset without being affected by the pulling force.

[0009] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a second spring is arranged between the linkage rod and the inner edge of the movable cavity. The second spring can enable the linkage rod to be reset after not being affected by the pulling force. When the linkage rod rotates, it can drive the linkage frame to rotate. When the linkage frame rotates, it can pull the flexible steel wire.

[0010] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a flexible steel wire is wound on the winding disc. The driving end of the winding disc penetrates through the operation frame and is linked with a linkage gear. When the linkage gear rotates, it can drive the winding disc to rotate. When the winding disc rotates, it can wind and unwind the flexible steel wire.

[0011] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a positioning sleeve is arranged in the connecting cylinder. One end of the positioning sleeve is provided with a guiding outer cylinder. The flexible steel wire penetrates through the centers of the positioning sleeve and the guiding outer cylinder. A guiding channel is opened on the upper surface of the connecting cylinder. A guiding groove is opened in one end of the telescopic sleeve facing the connecting cylinder. The guiding outer cylinder slides in the guiding groove, playing a guiding role in the telescopic movement of the telescopic sleeve.

[0012] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a threaded rod is arranged outside one end of the telescopic sleeve facing the connecting cylinder. The threaded rod is slidably connected in the guiding channel. An external thread of the threaded rod is in threaded transmission with a threaded sleeve. When the telescopic sleeve moves to a specified position, the threaded sleeve is tightened, and at this time, the position of the telescopic sleeve can be limited.

[0013] As a preferred technical solution of an electrocoagulation forceps for plastic surgery, a driving frame is arranged on the outer side of one end of the telescopic sleeve. A guiding groove is opened on the outer side of the connecting cylinder. The short end of the driving frame is slidably connected in the guiding groove. A rack is arranged on one side of the inner edge of the driving frame. The rack is meshed with the linkage gear. When the telescopic sleeve moves, the driving frame moves synchronously, and under the meshing transmission, the linkage gear rotates, facilitating the winding of the flexible steel wire and ensuring that both ends of the flexible steel wire are in a taut state (this state is when the elastic resetting member is not pulled).

[0014] As an optimal technical solution for electrocoagulation forceps for plastic surgery, the telescopic sleeve is rotatably connected to a gear one at one end toward the pliers head, the pliers head is arranged on the outside of the gear one, and the side of the gear one that is not at the axis is movably connected to a rotating disk, one end of the flexible steel wire is connected to the rotating disk, and an elastic reset part is arranged outside the end of the flexible steel wire toward the pliers head. Through the arrangement of the elastic reset part and the rotating disk, the pliers head can be linked to rotate.

[0015] The beneficial effects of the present invention are as follows: the electric coagulation forceps loosens the threaded sleeve, pushes the telescopic sleeve toward the position of the operating frame, the driving frame slides in the guide groove, the guide outer cylinder slides in the guide groove, the driving frame meshes with the linkage gear through the rack, and the winding disk rotates. At this time, the excessively long flexible steel wire can be stored, thereby ensuring that the operating movable handle can be linked to the pliers head, and the threaded sleeve is tightened. At this time, the telescopic sleeve can be limited, and the distance of the positioning sleeve can be adjusted without affecting the linkage of the pliers head.

[0016] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and the drawings.

[0031] Embodiment

[0032] Refer to Figure 1 and 2, which is an embodiment of the present invention. This embodiment provides an electrocoagulation forceps for plastic surgery, including an operating frame 100, an electrode head 102, and a forceps head 108; an electrode wire 101 is docked at the tail end of the operating frame 100, and one end of the electrode wire 101 away from the operating frame 100 is docked with the electrode head 102. The position where the electrode wire 101 extends into the operating frame 100 can be elongated to facilitate the storage of the telescopic sleeve 303. A fixed handle 103 is provided at the bottom end of the operating frame 100; an activity cavity 200 is opened in the operating frame 100, and an activity rotating shaft 105, a winding disc 205, and a positioning rotating shaft 206 are rotatably connected in the activity cavity 200. An activity handle 104 is provided on the outer side of the activity rotating shaft 105. A connecting cylinder 106 is provided at the tip of the operating frame 100. One end of the connecting cylinder 106 away from the operating frame 100 is movably connected with a telescopic sleeve 303, and the forceps head 108 is hinged at the tip of the telescopic sleeve 303.

[0033] Referring to Figure 3 , a linkage frame 207 and a linkage rod 208 are provided on the outer side of the positioning rotating shaft 206. One side of the activity rotating shaft 105 and the linkage rod 208 are mutually driven by a traction wire 202. A fixing plate 201 penetrates through the inner edge of the activity cavity 200. A positioning plate 203 is provided on the outer side of the traction wire 202 close to the fixing plate 201. A first spring 204 is provided between the positioning plate 203 and the fixing plate 201. When the activity rotating shaft 105 is pulled and rotated, the traction wire 202 can pull the linkage rod 208 to rotate, and under the action of the first spring 204, the activity rotating shaft 105 can be reset without being affected by the pulling force; a second spring 209 is provided between the linkage rod 208 and the inner edge of the activity cavity 200. Through the second spring 209, the linkage rod 208 can be reset without being affected by the pulling force. When the linkage rod 208 rotates, it can drive the linkage frame 207 to rotate, and when the linkage frame 207 rotates, it can pull the flexible steel wire 210;

[0034] Referring to Figure 1 , 3 As shown in FIGS. 6, 11 and 7, a flexible steel wire 210 is wound on the winding disc 205. The transmission end of the winding disc 205 penetrates through the operating frame 100 and is linked with a linkage gear 211. When the linkage gear 211 rotates, it can drive the winding disc 205 to rotate. When the winding disc 205 rotates, it can wind and unwind the flexible steel wire 210;

[0035] Referring to Figure 3 and 4, a positioning sleeve 300 is arranged inside the connecting cylinder 106. One end of the positioning sleeve 300 is provided with a guiding outer cylinder 302. The flexible steel wire 210 passes through the center of the positioning sleeve 300 and the guiding outer cylinder 302. A guiding channel 301 is formed on the upper surface of the connecting cylinder 106. A guiding groove 304 is formed inside one end of the telescopic sleeve 303 facing the connecting cylinder 106. The guiding outer cylinder 302 slides inside the guiding groove 304, playing a guiding role for the telescopic movement of the telescopic sleeve 303;

[0036] Refer to Figure 4 , a threaded rod 305 is arranged outside one end of the telescopic sleeve 303 facing the connecting cylinder 106. The threaded rod 305 is slidably connected inside the guiding channel 301. An external thread of the threaded rod 305 drives a threaded sleeve 306. After the telescopic sleeve 303 moves to a specified position, the threaded sleeve 306 is tightened, and at this time, the position of the telescopic sleeve 303 can be limited;

[0037] Refer to Figure 1 and 6 , a driving frame 307 is arranged outside one end of the telescopic sleeve 303. A guiding groove path 308 is formed on the outside of the connecting cylinder 106. The short end of the driving frame 307 is slidably connected inside the guiding groove path 308. A rack 309 is arranged on one side of the inner edge of the driving frame 307. The rack 309 meshes with the linkage gear 211. When the telescopic sleeve 303 moves, the driving frame 307 moves synchronously, and under the meshing drive, the linkage gear 211 rotates, facilitating the winding of the flexible steel wire 210 and ensuring that both ends of the flexible steel wire 210 are in a taut state (this state is when the elastic resetting member 312 is not pulled);

[0038] Refer to Figure 5 , a first gear 310 is rotatably connected inside one end of the telescopic sleeve 303 facing the clamping head 108. The clamping head 108 is arranged outside the first gear 310. A rotating disc 311 is movably connected to the side of the first gear 310 that is not at the axis. One end of the flexible steel wire 210 is docked with the rotating disc 311. An elastic resetting member 312 is arranged outside one end of the flexible steel wire 210 facing the clamping head 108. Through the arrangement of the elastic resetting member 312 and the rotating disc 311, the clamping head 108 can be driven to rotate.

[0039] Through this implementation, the following can be achieved: loosen the threaded sleeve 306, push the telescopic sleeve 303 towards the position of the operating frame 100, the driving frame 307 slides in the guiding groove 308, the guiding outer cylinder 302 slides in the guiding groove 304, the driving frame 307 meshes with the linkage gear 211 through the rack 309, and the winding disc 205 rotates. At this time, the overly long flexible steel wire 210 can be stored, so as to ensure that the operating activity handle 104 can drive the clamping head 108 in linkage, and tighten the threaded sleeve 306. At this time, the telescopic sleeve 303 can be limited. When pulling the activity handle 104, the activity rotating shaft 105 rotates, pulling the traction wire 202. At this time, the linkage rod 208 rotates to drive the linkage frame 207 to press down the flexible steel wire 210. At this time, under the action of the rotating disc 311, the first linkage gear 310 can be driven to rotate, so that the clamping head 108 rotates and opens. Under the action of the elastic resetting member 312, the clamping head 108 can be ensured to reset.

[0040] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine work of design, manufacturing and production.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
