[0003] In the prior art, the ultrasonic scalpel surgical device mainly includes an ultrasonic cutting hemostat, a transducer handle and a host. The transducer handle is the core component of the ultrasonic scalpel surgical device, and is used to convert the electrical signal output from the host end into a longitudinal vibration of ultrasonic frequency using the inverse piezoelectric effect, so that the blade of the ultrasonic cutting hemostat is forced to resonate. The common transducer handle is a reusable independent component, the front end of the transducer handle is connected to the ultrasonic cutting hemostat, and the cable module at the rear end is connected to the host. At present, the cable module has two structural forms: one is to set a wire clamping member in the shell, and use screws to lock the cable radially, but there is a risk of wearing the outer skin of the cable and the internal wiring harness insulation, which is easy to cause a short circuit; the second is to use potting glue to fix the cable in the shell, but if the transducer handle fails after the potting glue is cured, it is difficult to disassemble, analyze and repair the rear end of the transducer handle.

[0056] The technical solutions provided by the embodiments of this application will be described below with reference to the accompanying drawings.

[0057] As Figure 1 and Figure 2 shown, in a first aspect, this application provides a cable module 10, which is applied in a transducer handle 01 and is used to introduce a cable 500 led out from a host to a transducer 20. The cable module 10 includes a first housing 100, a clamping sleeve 200, a fixing sleeve 300, an adapter plate 400, and a cable 500, wherein:

[0058] The cable 500 has a first section 510, and the first section 510 of the cable 500 extends into the first housing 100. In one example, when the cable 500 and the first housing 100 are fixedly connected, the cable 500 passes through the rear end of the first housing 100, and a set length is reserved inside the first housing 100 for the cable 500. A part of the outer skin of the end of the first section 510 is stripped to lead out the wire harness 520 to be welded.

[0059] The clamping sleeve 200 is sleeved outside the first section 510 of the cable 500. One end of the clamping sleeve 200 is fixed inside the first housing 100, and this end of the clamping sleeve 200 is detachable relative to the first housing 100. In one example, the connection manner between the clamping sleeve 200 and the first housing 100 can be snap connection, concave-convex fit, threaded connection, etc.

[0060] The fixing sleeve 300 is fixed to the inner wall of the first housing 100, and the fixing sleeve 300 is detachable relative to the inner wall of the first housing 100. In one example, the connection manner between the fixing sleeve 300 and the inner wall of the first housing 100 can be snap connection, concave-convex fit, threaded connection, etc. At the same time, the inner wall of the fixing sleeve 300 is sleeved on the other end of the clamping sleeve 200, and the clamping sleeve 200 is clamped to the first section 510 of the cable 500 through the fixing sleeve 300, so that the fixing sleeve 300 clamps the clamping sleeve 200 and the first section 510 into one body. In another example, the fixing sleeve 300 and the first housing 100 can be made of hard metal and light metal to reduce weight and facilitate the lightweight of the cable module 10.

[0061] The adapter board 400 is fixed to the end of the fixing sleeve 300 away from the clamping sleeve 200, and the adapter board 400 is detachable relative to this end of the fixing sleeve 300 away from the clamping sleeve 200. In one example, the connection manner between the adapter board 400 and the fixing sleeve 300 can be snap connection, concave-convex fit, threaded connection, etc. At the same time, the adapter board 400 is electrically connected to the first section 510. In one example, the wire harness 520 of the adapter board 400 and the first section 510 is electrically connected by welding, wire contact locking, etc.

[0062] When assembling the above-mentioned cable module 10, first insert the first section 510 of the cable 500 from the rear end of the first housing 100, then sleeved the clamping sleeve 200 on the first section 510, and fix the clamping sleeve 200 inside the first housing 100; then fixedly connect between the fixing sleeve 300 and the inner wall of the first housing 100, and sleeved the fixing sleeve 300 on the clamping sleeve 200 to clamp the clamping sleeve 200 and the first section 510 together; finally, fix the adapter board 400 on the end of the fixing sleeve 300 away from the clamping sleeve 200, and electrically connect between the adapter board 400 and the first section 510 to complete the assembly. Since the first section 510 of the cable 500 is fixed in the first housing 100 through the fixing sleeve 300 and the clamping sleeve 200, it can avoid abrasion of the outer skin of the cable 500, reduce the risk of short circuit of the cable 500, and improve the connection strength of the cable 500. Since the adapter board 400 and the fixing sleeve 300, the fixing sleeve 300 and the first housing 100, the clamping sleeve 200 and the first housing 100, and the fixing sleeve 300 and the clamping sleeve 200 can all be detachably connected, the cable module 10 can be disassembled and repaired, improving the service life.

[0063] There are various structural forms of the clamping sleeve 200. In a preferred embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the clamping sleeve 200 includes a first sleeve body 210 and a second sleeve body 220. The second sleeve body 220 is connected to the first sleeve body 210. In one example, the second sleeve body 220 and the first sleeve body 210 can be an integral structure, prepared by processes such as injection molding and casting. In another example, the clamping sleeve 200 can be made of metal materials such as copper alloy and stainless steel to ensure the reliability of the structure. Among them:

[0064] Refer to Figure 6 and Figure 7 together. The first sleeve body 210 is connected to the first housing 100, and the first sleeve body 210 is detachable relative to the first housing 100. The first sleeve body 210 has a first through hole 211 for the first section 510 of the cable 500. In one example, the size of the first through hole 211 is adapted to the cable 500, and the inner diameter of the first through hole 211 can be slightly larger than the outer diameter of the cable 500 to facilitate the setting of the cable 500.

[0065] The second sleeve 220 is inserted into the interior of the fixed sleeve 300, and the second sleeve 220 includes at least three elastic arms 221 and at least three compression parts 222. The compression parts 222 and the elastic arms 221 are arranged one by one, and the compression parts 222 and the elastic arms 221 are connected. The multiple elastic arms 221 are arranged at intervals along the circumference of the first sleeve 210. The compression parts 222 protrude from the ends of the elastic arms 221 away from the first sleeve 210, and the compression parts 222 abut against the inner wall of the fixed sleeve 300 and the outer wall of the first section 510. In one example, an avoidance gap 230 is formed between adjacent elastic arms 221 to provide deformation space for adjacent elastic arms 221. In another example, the compression parts 222 are block structures, the elastic arms 221 are strip structures, and the block-shaped compression parts 222 protrude from the ends of the strip-shaped elastic arms 221.

[0066] The fixing sleeve 300 and the adapter plate 400 are both provided with a through hole for the first section 510 of the cable 500 to pass through. The first section 510 of the cable 500 is electrically connected to the adapter plate 400 through the through hole. In one example, the fixing sleeve 300 is provided with a first through hole 310, and the first through hole 310 is used for the first section 510 of the cable 500 to pass through it. The adapter plate 400 is provided with a second through hole 410, and the second through hole 410 is also used for the first section 510 of the cable 500 to pass through it. In one example, the adapter plate 400 is also provided with a chip 420, and the chip 420 is located on the side of the adapter plate 400 away from the fixing sleeve 300. The first section 510 of the cable 500 passes through the second through hole 410 and is connected to the chip 420. After the cable 500 is electrically connected to the chip 420, the adapter plate 400 and the fixing sleeve 300 are fixed as a whole by screws 600.

[0067] In the cable module 10, the cable 500 is passed through the first through hole 211 of the first sleeve 210 and through the accommodation space formed by the second sleeve 220, and then the first sleeve 210 is installed inside the first shell 100 to achieve a fixed connection between the clamping sleeve 200 and the first shell 100, and then the cable 500 is passed through the through holes of the fixing sleeve 300 and the adapter plate 400, and then the fixing sleeve 300 is sleeved on the outside of the second sleeve 220. The fixing sleeve 300 abuts against and compresses the compression portion 222, causing the compression portion 222 to drive the elastic arm 221 to deform radially inward and compress the avoidance gap 230, and the compression portion 222 and the elastic arm 221 move toward the cable 500, so that the outer side of the compression portion 222 abuts against the inner wall of the fixing sleeve 300, and the inner side of the compression portion 222 abuts against the outer wall of the first section 510, so that the elastic arm 221 is retracted through the fixing sleeve, and the compression portion 22 clamps the first section of the cable 500.

[0068] To improve the clamping force of the clamping sleeve 200 on the cable 500, specifically, as Figure 2 and Figure 3 shown, a plurality of wire-clamping teeth 2221 are formed on the inner wall of one end of the compression part 222 facing away from the first sleeve body 210. The plurality of wire-clamping teeth 2221 are arranged in sequence along the axis of the first sleeve body 210, and the wire-clamping teeth 2221 are used to clamp the outer wall of the cable 500. In the above-mentioned cable module 10, through the clamping action between the wire-clamping teeth 2221 and the outer wall of the cable 500, the tensile trend of the cable 500 along the axis direction of the first sleeve body 210 can be blocked, the tensile resistance between the compression part 222 and the cable 500 is increased, so that the wire-clamping teeth 2221 lock the cable 500, and thus the fixation of the cable 500 is realized. In one example, the number of the wire-clamping teeth 2221 is two, three, four or more than four, and the shape of the wire-clamping teeth 2221 can be structures such as serrated shape and wedge shape.

[0069] To facilitate the connection between the first sleeve body 210 and the first housing 100, specifically, a plurality of limiting grooves 212 are formed on the outer wall of the first sleeve body 210, and a plurality of limiting blocks 110 are formed on the inner wall of the first housing 100. The plurality of limiting grooves 212 are arranged at intervals along the circumferential direction of the outer wall of the first sleeve body 210. Similarly, the plurality of limiting blocks 110 are arranged at intervals along the circumferential direction of the inner wall of the first housing 100. The limiting blocks 110 and the limiting grooves 212 are clamped with each other, so as to realize the convenient, fast and detachable connection between the first sleeve body 210 and the first housing 100. In one example, the number of the limiting grooves 212 and the limiting blocks 110 can be two, three, four or more than four, and the shapes of the limiting grooves 212 and the limiting blocks 110 can be structures such as rectangular shape, wedge shape and trapezoidal shape.

[0070] To improve the connection reliability of the cable 500 inside the first housing 100, specifically, the cable 500 is fixed by potting inside the first housing 100, and part of the first section 510 extends out of the potting area inside the first housing 100. On the one hand, the cable 500 can be firmly fixed at the rear end of the first housing 100 through the potting effect of the potting area, improving the connection reliability. On the other hand, the potting area can also isolate the inside and outside of the first housing 100, improving the sealing performance of the cable module 10.

[0071] To facilitate assembly, specifically, as Figure 3 and Figure 5As shown, at one end of the first body 210 away from the elastic arm 221, a receiving groove 213 is formed. The receiving groove 213 surrounds the outside of the first through hole 211 and is in communication with the first through hole 211. The receiving groove 213 is used to receive the overflowing colloid during potting. In the above-mentioned cable module 10, the overflowing colloid during potting is received by the receiving groove 213, so as to facilitate the control of the amount of colloid during potting between the cable 500 and the first housing 100. On the one hand, it enables the assembly of the cable module 10 to be more convenient and controllable. On the other hand, it allows a larger amount of colloid to ensure the sealing performance between the cable 500 and the first housing 100.

[0072] To facilitate the installation of the cable 500 in the first housing 100, in a preferred embodiment, as Figure 1 and Figure 2 shown, the cable module 10 further includes a protective sleeve 700. The protective sleeve 700 is sleeved on the part of the cable 500 other than the first section 510. One end of the protective sleeve 700 extends into the first housing 100, and the protective sleeve 700 is fixed in the first housing 100 by potting. On the one hand, it can protect the part of the cable 500 other than the first section 510 through the protective sleeve 700, improving the connection reliability and sealing performance of the cable 500 inside the first housing 100.

[0073] There are various structural forms of the protective sleeve 700. Specifically, as Figure 2 shown, the protective sleeve 700 includes a third body 710 and a positioning portion 720. A second through hole 730 is formed in the third body 710 for receiving the cable 500. The positioning portion 720 is provided at one end of the third body 710 extending into the first housing 100, and the positioning portion 720 protrudes from the end of the third body 710. The first housing 100 has a third through hole 120 and a groove 130. The groove 130 is stepped and has a large end and a small end. The groove 130 is provided on the inner wall of the first housing 100 and opens into the third through hole 120. The small end of the groove 130 is in communication with the third through hole 120. The large end of the groove 130 is used to receive the potting portion 800 formed by potting. The potting portion 800 is used to abut the positioning portion 720 in the small end of the groove 130. The small end of the groove 130 is used to cooperate with the positioning portion 720 to prevent the protective sleeve 700 from axially moving in the first housing 100. In one example, the protective sleeve 700 can be made of silicone material, rubber material, etc., and the protective sleeve 700 is coaxially assembled with the rear end of the first housing 100. In one example, a guiding groove 731 is further formed on the third body 710. The guiding groove 731 surrounds the outside of the second through hole 730 and is in communication with the second through hole 730, and is used to guide the glue to pot the assembly gap between the second through hole 730 and the cable 500 when potting the protective sleeve 700, so as to achieve the effect of strengthening the seal.

[0074] In the above-mentioned cable module 10, the protective sleeve 700 is inserted from the front end of the first housing 100, the positioning portion 720 abuts against the small end of the groove 130, the third sleeve body 710 penetrates through the rear end of the first housing 100, the cable 500 is inserted into the second through hole 730 of the third sleeve body 710, and extends out of the protective sleeve 700 by a set length to form the first section 510. Then, the protective sleeve 700 is quantitatively potted with potting glue from the front end of the first housing 100, and after the glue is cured, a potted portion 800 is formed to complete the sealed connection between the protective sleeve 700, the cable 500, and the first housing 100, and can reinforce the fixed connection between the cable 500 and the first housing 100.

[0075] To further protect the cable 500, in a preferred embodiment, as Figure 2 shown, the cable module 10 further includes an insulating sleeve 900. The insulating sleeve 900 is inserted into the first housing 100 and sleeved outside the adapter board 400. The insulating sleeve 900 is used to isolate the adapter board 400 from the first housing 100 made of metal. In one example, the insulating sleeve 900 can be made of a hard insulating plastic material to obtain the effect of withstanding high medical temperature and pressure and steam sterilization. In the above-mentioned cable module 10, the insulating sleeve 900 isolates the inner wall of the first housing 100 from the adapter board 400, the wire harness 520 of the cable 500, and the solder joints between the cable 500 and the adapter board 400, and can prevent the first housing 100 made of metal from contacting the adapter board 400, the wire harness 520 of the cable 500, and the solder joints between the cable 500 and the adapter board 400, thereby preventing short circuits.

[0076] Second, as Figure 1 shown, the present application provides a transducer handle 01, which is applied to an ultrasonic scalpel surgical device, used to connect an ultrasonic cutting hemostat and a host, and convert the electrical signal input by the host into ultrasonic vibration of the ultrasonic cutting hemostat. The transducer handle 01 includes the cable module 10, the transducer 20, and the second housing 30 according to any one of the above technical solutions; the second housing 30 and the first housing 100 are in interference fit to achieve a tight fixed connection between the second housing 30 and the first housing 100. The transducer 20 is disposed inside the second housing 30, and the transducer 20 is electrically connected to the adapter board 400 of the cable module 10 to achieve the electrical control operation of the transducer 20.

[0077] In one example, the transducer handle 01 further includes an isolation sleeve 40 and a sealing ring 50, and the sealing connection is achieved through the sealing ring 50 disposed between the second housing 30 and the first housing 100 to realize the sealing of the module composed of the second housing 30 and the first housing 100 and prevent the entry of external impurities and liquids. The isolation sleeve 40 is sleeved on the end of the transducer 20 close to the adapter plate 400, and the isolation sleeve 40 is used to isolate the transducer 20 and the adapter plate 400 to insulate the harness 520 of the transducer 20, the adapter plate 400 and the cable 500, thereby improving the reliability of the product.

[0078] In one example, a connection portion 130 cooperating with the second housing 30 is formed at the front end of the first housing 100. An annular groove 141 is formed in the connection portion 130. The sealing ring 50 is disposed in the annular groove 141. When the second housing 30 is sleeved on the connection portion 130 of the first housing 100, the sealing ring 50 is compressed between the opposite surfaces of the second housing 30 and the annular groove 141 to achieve the sealed connection between the second housing 30 and the first housing 100.

[0079] When assembling the above-mentioned transducer handle 01, after inserting the cable module 10 into the first housing 100 through the first section of the cable 500, clamping the sleeve 200 is fixed inside the first housing 100, the fixing sleeve 300 is fixed inside the first housing 100 to clamp the clamping sleeve 200 and the first section 510 together, the adapter plate 400 is fixed on the fixing sleeve 300 and electrically connected to the first section 510 to complete the assembly, the transducer 20 is disposed in the second housing 30, and the electrical connection between the transducer 20 and the adapter plate 400 is established, and the fixed connection between the second housing 30 and the first housing 100 is achieved through the interference fit between the second housing 30 and the first housing 100 to complete the assembly of the transducer handle 01. Since the first section 510 of the cable 500 in the cable module 10 is fixed inside the first housing 100 through the fixing sleeve 300 and the clamping sleeve 200, it can prevent the outer skin of the cable 500 from being scratched, reduce the risk of short circuit of the cable 500, and improve the connection strength of the cable 500. Since the adapter plate 400 and the fixing sleeve 300, the fixing sleeve 300 and the first housing 100, the clamping sleeve 200 and the first housing 100, the fixing sleeve 300 and the clamping sleeve 200, and the second housing 30 and the first housing 100 can all be detachably connected, the cable module 10 can be disassembled and repaired, thereby improving the service life of the transducer handle 01. Since there is an interference connection between the second housing 30 and the first housing 100, the transducer handle 01 has high reliability and good product performance.
