Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to a repeatedly used ultrasonic scalpel handle. BACKGROUND

[0002] For the common multiple breast fibroma, breast nodule and other diseases in the breast department, generally a minimally invasive puncture surgery is adopted to sample the breast lesion tissue and partially or completely remove the abnormal tissue. At present, in other open and endoscopic surgeries, an ultrasonic scalpel is generally used to replace an electric knife for removing the lesion tissue. The principle of the ultrasonic scalpel is that a metal blade is mechanically oscillated at an ultrasonic frequency by an ultrasonic frequency generator to vaporize water molecules in the tissue, break hydrogen bonds of proteins, collapse cells, cut or coagulate the tissue, and close blood vessels. The advantages of the ultrasonic scalpel are: (1) effective, which can accurately cut the lesion tissue including hard calcified tissue and fascia tissue with small thermal damage and fast healing; (2) convenient, which has less smoke and eschar to make the surgical field clear, faster cutting speed, and shorter surgery time; and (3) safe, which has no electric current passing through the human body and less bleeding. The minimally invasive breast puncture ultrasonic scalpel is to introduce the ultrasonic scalpel into the minimally invasive surgery to quickly and accurately cut the tissue by using the principle of the ultrasonic scalpel, and to have little bleeding by using the self-coagulation feature of the ultrasonic scalpel. The traditional minimally invasive breast puncture rotary scalpel is based on the mechanical shearing principle, and has high requirements for the blade edge and the matching gap, which is difficult to produce and manufacture, thereby causing the problems of the blade edge of the knife tip not being able to penetrate into the tissue, cutting failure, clamping, pulling, irregular cutting edge, incomplete cutting, and the like, and further causing the problems of slow wound healing, especially the problems of hard calcified tissue not being easy to separate and cut, and fascia tissue being easy to slide and difficult to position and cut. Meanwhile, based on the cold knife cutting principle, bleeding is inevitable during the surgery, which is not conducive to the timely observation of the cutting condition by the doctor. The minimally invasive breast puncture ultrasonic scalpel can solve the above problems of the traditional minimally invasive breast puncture rotary scalpel in principle. The advantages of the minimally invasive breast puncture ultrasonic scalpel are: (1) effective, which can easily remove and collect the breast lesion tissue; (2) convenient, which has shorter surgery time and does not need hospitalization; and (3) safe, which has small surgery incision and short healing time.

[0003] At present, the breast puncture ultrasonic scalpel generally comprises a one-time use ultrasonic surgical scalpel, a repeatedly used ultrasonic surgical scalpel handle, and a repeatedly used transducer. The ultrasonic surgical scalpel handle and the transducer are two independent devices, and each has a power line. When the breast puncture ultrasonic scalpel is used, the ultrasonic surgical scalpel, the ultrasonic surgical scalpel handle, and the transducer need to be assembled in sequence, and then the power lines of the ultrasonic surgical scalpel handle and the transducer are connected to the main machine.

The transducer power supply structure 3 includes a conductive ring seat limiting support 30, a conductive ring seat 31, a conductive ring 32, and a transducer 33, which is used to supply power to the transducer inside the ultrasonic scalpel handle. Assemble the ultrasonic scalpel handle 1: First, assemble the driving structure 2, that is, first fix the motor gear 21 to the output shaft of the encoder motor 20, then put the encoder motor 20 into the groove of the handle lower shell 11, and fix the motor cover 22 on the handle lower shell 11 with screws; then assemble the transducer power supply structure 3, that is, first put two groups of conductive rings into the conductive ring seat 31, then guide the cable on the conductive ring 32 out of the hole on the conductive ring 32, bury it into the groove on the surface of the conductive ring seat 31, and fix it with hot melt glue.

[0021] The design has the following advantages: (1) in the design, the cutout on the conductive ring seat limiting support is only a distance, which meets the needs of the transducer movement and installation, and can avoid the conductive ring seat moving out between the lower shell of the knife handle and the conductive ring seat limiting support; (2) in the design, the side of the conductive ring seat limiting support is provided with an elastic arm buckle, which can avoid the conductive ring seat from easily sliding out and affecting the assembly of the ultrasonic surgical knife and the ultrasonic surgical knife handle; (3) in the design, the conductive ring seat is provided with an ultrasonic knife rod supporting surface, which ensures that the conductive ring in the conductive ring seat is in close contact with the copper ring on the transducer after the transducer and the ultrasonic knife rod are tightened; (4) in the design, a separate power supply cover is used, which is conducive to the connection of the cable and the subsequent maintenance; (5) in the design, the conductive ring-copper ring wireless contact type power supply mode not only realizes the rotating installation of the transducer, but also realizes the movement of the transducer after being connected with the ultrasonic knife rod, and avoids the power supply cable of the transducer from being wound due to rotation, so as to realize the integrated design of the transducer and the ultrasonic surgical knife handle, and further make the installation and use of the breast puncture ultrasonic knife more convenient.

[0022] As Figures 5-6As shown, the minimally invasive breast puncture ultrasonic knife includes an ultrasonic surgical knife 4 and an ultrasonic surgical knife handle 1, wherein the ultrasonic surgical knife 4 is disposable, and the ultrasonic surgical knife handle 1 is reusable. The use process of the minimally invasive breast puncture ultrasonic knife is as follows: firstly, the assembly process, that is, first determine the transducer 33 on the ultrasonic surgical knife handle 1 in the initial position, without sliding out (if the transducer slides, the transducer rotating part can be pulled outward, and the internal buckle of the ultrasonic surgical knife handle will make the transducer stay in the initial position), then insert the plug block of the ultrasonic surgical knife handle 1 into the insertion opening of the ultrasonic surgical knife 4, then buckle the ultrasonic surgical knife 4 and the ultrasonic surgical knife handle 1, then rotate the transducer 33 until it is tightened, finally insert the negative pressure pipe and the air supplement pipe into the main machine, and insert the power cord 18 of the ultrasonic surgical knife handle 1 into the main machine; secondly, the working process, after the main machine is turned on, the ultrasonic surgical knife will start the automatic self-checking, that is, the encoder motor 20 rotates to drive the ultrasonic knife rod to move, to ensure that the ultrasonic knife rod automatically returns to the initial position. Before puncture, confirm that the indicator light is in the off state (switch by pressing the OPEN / CLOSE button), press the forward key on the button to close the sampling groove, and this process does not excite the ultrasonic work, and the air supplement end and the negative pressure end are both closed. After puncture reaches the sampling position, press the backward key on the button to open the sampling groove, at this time the air supplement end is switched to the negative pressure opening, and the negative pressure end is also opened. Before ultrasonic cutting, confirm that the indicator light is in the on state (switch by pressing the OPEN / CLOSE button), press the forward key on the button to cut the tissue, in this process, the negative pressure end remains open, and the air supplement end also remains open, the ultrasonic knife rod is excited to cut, and when the cutting is completed, the ultrasonic stops exciting. Press the backward key on the button, in this process, the negative pressure end remains open, and the air supplement end is switched to the air supplement opening. During the sampling process, the indicator light is in the constant-on state, and the above-mentioned operations (forward key and backward key on the button) can be repeated to realize continuous sampling. After the sampling work is completed, confirm that the indicator light is in the off state (switch by pressing the OPEN / CLOSE button), pull out the minimally invasive breast puncture ultrasonic knife, press the two side knobs of the knife collection bin, pull out the collection bin, and pour out the sampling tissue. Finally, the disassembly process, that is, first loosen and remove the transducer, then press the release button on the ultrasonic surgical knife, and take down the ultrasonic surgical knife from the ultrasonic surgical knife handle.
