Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic cutting equipment, and in particular to a portable handheld ultrasonic knife. Background Art

[0002] Ultrasonic cutting equipment is a kind of equipment that uses ultrasonic energy for cutting. It has the advantages of cutting without cutting edges, environmental protection, no danger, and high precision, and is suitable for cutting various soft and elastic materials. Ultrasonic knife is an ultrasonic cutting equipment that uses advanced ultrasonic energy technology. The host of the ultrasonic knife converts high-frequency electrical energy into ultrasonic mechanical vibration energy. The transducer in the handle converts the high-frequency electrical energy provided by the host generator into ultrasonic energy and transmits it to the knife head.

[0003] In the patent document with the publication number CN106142156A, a portable ultrasonic hand-held cutter is provided, the main features of which are that the piezoelectric ceramic transducer is connected to the tool head through a 12.9 grade high-strength screw, the piezoelectric ceramic transducer front cover is equipped with a nylon washer A on the top of the zero vibration point, and a nylon washer B on the bottom, the transducer middle tube and the transducer upper tube are threaded to press the nylon washer A and the nylon washer B, and the piezoelectric ceramic transducer is fixed inside the transducer housing, the inner side of the transducer middle tube is equipped with an insulating sleeve B, and the surface of the piezoelectric ceramic transducer ceramic sheet is equipped with an insulating sleeve A to prevent the electrode from connecting to the metal, the transducer tube rear cover is connected to the transducer middle tube through a thread, and the transducer tube rear cover is provided with a ventilation hole and an aviation plug-in connection port, and the aviation plug-in connection port is connected to the signal cable connected to the ultrasonic drive power supply through a cable line. It has the advantages of small actuator size, light weight, low noise, low energy consumption, convenient and flexible operation, wide application, and can effectively reduce costs and improve production efficiency.

[0004] The above-mentioned device improves cutting efficiency by applying kinetic energy to the tool head. Since no protective mechanism is provided on the outside of the tool head, accidents are prone to occur when the tool head is opened. If an external protective mechanism is adopted, such as installing a scabbard, once the scabbard comes into contact with the started tool head, the scabbard will be cut by the action of the tool head with kinetic energy, thereby causing unnecessary damage to the scabbard.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0026] Refer to Figures 1-4, a portable handheld ultrasonic scalpel, including a handle 1, in the middle of the front of the handle 1 is fixedly connected with an ultrasonic scalpel body 5. The ultrasonic scalpel body 5 includes a knife handle and a blade. A protection mechanism 3 is sleeved on the side of the knife handle of the ultrasonic scalpel body 5. A fixing mechanism 4 is installed at the upper end of the protection mechanism 3. A grip sleeve mechanism 2 is sleeved on the outside of the protection mechanism 3. The inner wall of the grip sleeve mechanism 2 is slidably connected with the protection mechanism 3. One end of the grip sleeve mechanism 2 close to the handle 1 is fixedly connected with the handle 1, and one end of the protection mechanism 3 close to the handle 1 has no connection relationship with the handle 1.

[0027] Refer to Figures 1-4 , the grip sleeve mechanism 2 includes a cylinder body 201. The cylinder body 201 is a cylindrical sleeve structure. A chute 202 is opened above the cylinder body 201. Two vertical plates 203 are fixedly connected to both sides of the chute 202. The two vertical plates 203 are arranged in parallel on both sides of the chute 202. The upper ends of the vertical plates 203 are fixedly connected with a top plate 204. The top plate 204 extends parallel to the chute 202 for a certain distance. A plurality of uniformly arranged upper teeth 205 are fixedly connected to the lower surface of the top plate 204 away from one side of the top plate 204. When using the ultrasonic scalpel, by grasping the cylinder body 201 with the hand, the effect of holding the ultrasonic scalpel is achieved. The longitudinal section of the cylinder body 201 is polygonal, so as to achieve a certain anti-slip effect. The grip sleeve mechanism 2 is responsible for providing an internal space for installing components to ensure the stability of the working process.

[0028] Refer to Figures 1-4 , a plug 206 is fixedly connected to one end of the chute 202 and the vertical plate 203 away from the handle 1. The lower part of the upper teeth 205 can be engaged with the fixing mechanism 4. The fixing mechanism 4 can displace along the chute 202, thereby driving the protection mechanism 3 to move back and forth. The positioning of the fixing mechanism 4 is realized through the upper teeth 205, and the limit of the fixing mechanism 4 is realized through the plug 206, so as to ensure the normal use of the protection mechanism 3.

[0029] Refer to Figures 1-4 , the protection mechanism 3 includes a sliding sleeve 302301. A fixing plate is fixedly connected to the upper end of the sliding sleeve 302301. The outside of the sliding sleeve 302301 is slidably connected with the inner wall of the cylinder body 201. A guiding column 303 is fixedly connected to the middle of the upper surface of the fixing plate. The protection mechanism 3 is sleeved inside the ultrasonic scalpel body 5 and the grip sleeve mechanism 2 is sleeved on the outside. The protection mechanism 3 can displace along the grip sleeve mechanism 2, so that the protection mechanism 3 is sleeved outside the blade of the ultrasonic scalpel body 5, thereby achieving the effect of protecting the outside of the blade.

[0030] Refer to Figures 1-4, the fixing mechanism 4 includes a spring 401. The lower end of the spring 401 is fixedly connected to the fixing plate. The spring 401 is sleeved on the side surface of the guiding column 303. The upper end of the spring 401 is fixedly connected with a pressing block 402. A cylindrical groove 403 is formed in the middle of the lower surface of the pressing block 402. The internal shape of the cylindrical groove 403 is the same as that of the guiding column 303 and is slidably connected with the guiding column 303. Lower clamping teeth 404 are fixedly connected to the upper surfaces on both sides of the pressing block 402. Press the fixing mechanism 4 to make the pressing block 402 move downward along the guiding column 303. The guiding column 303 is inserted into the internal part of the cylindrical groove 403, so that the lower clamping teeth 404 are disengaged from the upper clamping teeth 205, thereby making the fixing mechanism 4 enter a state where it can be pushed. Release the fixing mechanism 4, and the spring 401 pushes the pressing block 402 upward, so that the upper surface of the lower clamping teeth 404 contacts the adjacent surfaces of the two upper clamping teeth 205. At this time, the upper clamping teeth 205 play a role in limiting the lower clamping teeth 404, thereby making the fixing mechanism 4 enter a locked state, and further ensuring the normal use of the protection mechanism 3.

[0031] Refer to Figures 1-4 , an extension block 405 is fixedly connected to the middle of the upper surface of the pressing block 402. A push plate 406 is fixedly connected to the upper end of the extension block 405. The push plate 406, the extension block 405 and the top plate 204 are slidably connected. By pressing or releasing the push plate 406, the fixing mechanism 4 is made to enter a state where it can be pushed or a locked state. Push the push plate 406 to make the fixing mechanism 4 displace along the sliding groove 202, thereby driving the protection mechanism 3 to reach a specified position.

[0032] Working principle: When using the ultrasonic scalpel, grasping the cylinder body 201 by hand can achieve the effect of holding the ultrasonic scalpel. The longitudinal section of the cylinder body 201 is polygonal, thereby achieving a certain anti-slip effect. The grip sleeve mechanism 2 is responsible for providing an internal space for installing components to ensure the stability of the working process. By pressing or releasing the push plate 406, the fixing mechanism 4 is made to enter a state where it can be pushed or a locked state. Push the push plate 406 to make the fixing mechanism 4 displace along the sliding groove 202, thereby driving the protection mechanism 3 to reach a specified position;

[0033] Press the fixing mechanism 4 to make the pressing block 402 move downward along the guiding column 303. The guiding column 303 is inserted into the internal part of the cylindrical groove 403, so that the lower clamping teeth 404 are disengaged from the upper clamping teeth 205, thereby making the fixing mechanism 4 enter a state where it can be pushed. Release the fixing mechanism 4, and the spring 401 pushes the pressing block 402 upward, so that the upper surface of the lower clamping teeth 404 contacts the adjacent surfaces of the two upper clamping teeth 205. At this time, the upper clamping teeth 205 play a role in limiting the lower clamping teeth 404, thereby making the fixing mechanism 4 enter a locked state, and further ensuring the normal use of the protection mechanism 3.
