Abstract
Description
Technical Field
[0001] The invention relates to an ultrasonic surgical knife handle. Background Art
[0002] Ultrasonic Scalpel (also known as ultrasonic scalpel or ultrasonic hemostatic scalpel) is an advanced medical device that is widely used in surgical operations. Ultrasonic scalpels can not only cut tissues, but also have coagulation functions. During the cutting process, the high-frequency vibration of the blade can close the blood vessels, thereby reducing bleeding. The ultrasonic scalpel consists of a handle and a knife. The transducer and circuit structure are set inside the handle. The knife is connected to the handle. During surgery, the doctor holds the handle and inserts the knife into the human body to perform the operation. The knife is usually disposable and will be discarded after use; but the handle is relatively expensive and is usually reused after strict disinfection.
[0003] During the disinfection process, the handle is usually washed with water to remove surface stains. However, during water washing, since the mouth of the mounting hole connecting the front of the handle to the tool is open, it is very easy for liquid to enter the interior of the handle through this opening, causing damage to the circuit structure and transducer inside the handle, resulting in a significant shortening of the service life of the handle.

[0045] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings to make the advantages and features of the present invention more easily understood by those skilled in the art. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
[0046] Example 1
[0047] See also Figures 1 to 6The ultrasonic surgical knife handle shown includes a handle body 1, an inner cavity of the handle body 1 is provided with a transducer assembly and other circuit elements, a front portion of the handle body 1 is provided with a connector 11, a mounting hole 13 is provided on the connector 11, and a tool can pass through the mounting hole 13 and connect with the connector 11, thereby being connected to the handle body 1; the handle body 1 also has a gripping handle 12 located at the lower portion, after the handle body 1 is powered on, the operator can hold the gripping handle 12 and operate the handle or button and other operating elements on the handle body 1 to perform surgical operations on the surgical site through the tool.
[0048] The handle also includes a power connection line 2 connected to the handle body 1. The power connection line 2 includes a conductive line 21 and a connection base 22 fixed to one end of the conductive line 21. The other end of the conductive line 21 is electrically connected to the circuit components located in the handle body 1. The connection base 22 has a connection structure for connecting to an external power source. The connection base 22 can be inserted into the mounting hole 13. Specifically, the power connection line 2 is connected to the lower portion of the grip 12.
[0049] Thus, the power cable 2 has two different usage states. In the first usage state, the power cable 2 is connected to an external power source and can be used for surgical operations after the handle body 1 is powered on. In the second usage state, the conductive wire 21 bends forward and upward, and the connecting seat 22 is cooperatively inserted into the mounting hole 13, so that the mounting hole 13 is blocked. In this way, when the handle is cleaned or disinfected, the mounting hole 13 can be blocked to prevent liquid from entering the inner cavity of the handle body 1 through the mounting hole 13 during the cleaning and disinfection process and causing damage to the internal circuit components of the handle. The power cable 2 can be used for multiple purposes and also avoids the problems of needing to store and easily lose the waterproof end plug.
[0050] As shown in the accompanying drawings, the connecting seat 22 is generally cylindrical in shape. The outer periphery of the connecting seat 22 includes a sealing ring 22a that protrudes radially outward. When the connecting seat 22 is inserted into the mounting hole 13, the outer periphery of the connecting seat 22 is sealedly connected to the circumferential wall of the mounting hole 13 via the sealing ring 22a, thereby completely blocking the mounting hole 13 and isolating the inner cavity of the handle body 1 from the outside, thereby preventing liquid from entering the inner cavity of the handle body 1 during cleaning and disinfection. In this embodiment, multiple sealing rings 22a are provided at intervals along the length of the connecting seat 22, thereby forming a multi-layer seal to fully prevent liquid from entering the inner cavity of the handle body 1.
[0051] The connector 22 includes a base body 221 having a mounting cavity, and an electrical connection element 223 and a connector 222 fixedly disposed in the mounting cavity. The conductive wire 21 extends from one end of the base body 221 into the mounting cavity and is fixedly connected to the connector 222. The electrical connection element 223 extends from the other end of the base body 221 into the mounting cavity of the base body 221. The electrical connection element 223 is fixedly connected to the connector 222 and electrically connected to the conductive wire 21. The connection structure is disposed in the electrical connection element 223.
[0052] Specifically, the seat body 221 is made of plastic or silicone material, and when inserted into the mounting hole 13, it can fit well with the circumferential hole wall of the mounting hole 13 to block the mounting hole 13. The external power supply includes an external power line 3, and the power connection line 2 is connected to the power supply after being connected to the external power line 3. Figure 2 As shown, the external power cord 3 has a plug connector 31, a power adapter 33 and a plug 32. The plug 32 can be plugged into a socket connected to an AC power source to connect to the power supply. The plug connector 31 can be pluggably matched with the connection structure on the connection socket 22 and connected to the power connection element 223. Figure 6 As shown, a slot 224 is formed on the connection base 22 for at least partially inserting the plug connector 31. The connection structure is a socket and a positioning protrusion provided on the power connection element 223. When the plug connector 31 is inserted into the slot 224, it can be matched with the socket and the positioning protrusion to connect with the power connection element 223, thereby electrically connecting to the power connection element 223.
[0053] like Figure 3 、 Figure 4 As shown, the power connection line 2 also includes a fixing seat 24, a waterproof ring 25 and a limit seat 23 which are sequentially sleeved on the conductive wire 21. A connecting hole is opened on the handle body 1, which is connected to the inner cavity of the handle body 1, wherein the waterproof ring 25 is cooperatively inserted into the above-mentioned connecting hole and is sealed with the circumferential hole wall of the connecting hole; the fixing seat 24 is located in the inner cavity of the handle body 1, and the limit seat 23 is located outside the handle body 1, which prevents water from entering the position where the power connection line 2 is connected to the handle body 1.
[0054] In this embodiment, the above-mentioned fixing seat 24, waterproof ring 25 and limiting seat 23 are integrally formed as a whole component and covered on the outside of the conductive wire 21. During assembly, the two outer shells of the handle body 1 are docked with each other to clamp the waterproof ring 25 between the two, so that the assembly of the power connection line 2 can be realized.
[0055] In summary, the ultrasonic surgical knife handle provided in this embodiment has a power connection line 2 attached to the handle body 1, which can not only directly connect to an external power source to power the circuit components of the handle body 1, but also can insert the connecting seat 22 on the power connection line 2 into the mounting hole 13 on the front of the handle body 1 during cleaning and disinfection, so that the mounting hole 13 is blocked, thereby preventing liquid from entering the inner cavity of the handle body 1 from the mounting hole 13 during the cleaning and disinfection process and causing damage to its internal circuit components. This is not only convenient to operate, but also does not require the additional configuration of waterproof end plugs, avoiding the problems of independent storage and easy loss caused by the independent configuration of waterproof end plugs.
[0056] Example 2
[0057] See also Figures 7 to 15 The ultrasonic surgical knife handle shown in the figure differs from that in Example 1 mainly in the following two aspects:
[0058] First, in the ultrasonic surgical knife handle provided in this embodiment, the connection base 22 of the power connection cable 2 is further provided with an annular limiting flange 22b. Specifically, the annular limiting flange 22b is provided on the outer peripheral portion of the base body 221 and extends radially outward. When the connection base 22 is inserted into the mounting hole 13, the annular limiting flange 22b abuts against the handle body 1, specifically, axially against the outer end of the connector 11. In this way, when the connection base 22 is inserted into the mounting hole 13, it is convenient to know whether the connection base 22 has been inserted into the mounting hole 13. At the same time, the annular limiting flange 22b abuts against the handle body 1, thereby enhancing the sealing at the contact point between the two and further improving the waterproof effect.
[0059] Secondly, in the ultrasonic scalpel handle provided in this embodiment, a waterproof component is added between the operating part of the handle and the handle body 1 to prevent liquid from entering the interior of the handle body 1 from the position where the operating part is connected to the handle body 1, further improving the overall waterproof performance of the ultrasonic scalpel handle, thereby facilitating the cleaning and sterilization operations of the ultrasonic scalpel handle.
[0060] Specifically, the operating part is movably provided on the handle body 1, and a mounting groove (not shown in the figure) is provided on the handle body 1. The operating part is partially inserted into the mounting groove and connected to the handle body 1, so as to drive the operating part to move when the ultrasonic scalpel handle is used to implement the corresponding surgical operation. The waterproof component specifically includes a flexible and deformable waterproof cover, which is cooperatively covered on the outside of the operating part, and the outer peripheral portion of the waterproof cover is sealedly connected to the circumferential groove wall of the mounting groove, so that the operating part can be protected in the space formed between the waterproof cover and the handle body 1. At the same time, since the waterproof cover can be deformed, it does not affect the normal movement of the operating part or affect the surgical operation. The waterproof cover is specifically made of soft rubber material, which can deform when under pressure and return to its original shape after the pressure is released.
[0061] Specifically, in the ultrasonic surgical knife handle of this embodiment, the operating components include a button component 4 and a grip component 5. Correspondingly, a first waterproof component 6 and a second waterproof component 7 are provided on the handle. Figures 7 to 15 The structures of the first waterproof component 6 and the second waterproof component 7 are respectively described in detail.
[0062] The handle body 1 is provided with a first mounting slot. The button assembly 4 includes a plurality of buttons 41. The pressing positions of the buttons 41 are located outside the handle body 1. The buttons 41 are movably inserted into the first mounting slot and connected to components within the handle body 1. The first waterproof assembly 6 includes a first waterproof cover 61 having a receiving cavity open toward the first mounting slot. The button assembly 4 can be movably received within the receiving cavity.
[0063] In this embodiment, the first waterproof assembly 6 further includes a first waterproof seat 62, which is circumferentially closed and annular and cooperatively embedded in the first mounting groove. The outer peripheral edge of the first waterproof cover 61 is clamped between the first waterproof seat 62 and the circumferential groove wall of the first mounting groove. In specific configuration, the hardness of the first waterproof seat 62 is greater than the hardness of the first waterproof cover 61. During installation, when the two half shells forming the outer shell of the handle body 1 have not yet been aligned, after the button assembly 4 is assembled to the handle body 1, the first waterproof cover 61 is sleeved onto the outside of the button assembly 4, and then the outer peripheral edge of the first waterproof cover 61 is clamped into the first mounting groove via the first waterproof seat 62. The two half shells are then assembled accordingly. This facilitates the assembly of the first waterproof cover 61, avoids the formation of a gap between the first waterproof cover 61 and the handle body 1, and improves the waterproof performance.
[0064] The handle body 1 also defines a second mounting slot. The grip assembly 5 includes an operating handle 51 and a connecting rod 52, which are fixedly mounted to each other. The operating handle 51 is located outside the handle body 1, and the connecting rod 52 is movably mounted within the second mounting slot and connected to the handle body 1. The second waterproof assembly 7 includes a second waterproof cover 71. The second waterproof cover 71 includes a fixed portion 71a fixedly mounted outside the operating handle 51, and a connecting portion 71b extending from the fixed portion 71a toward the handle body 1. The connecting portion 71b is sealingly connected to the circumferential groove wall of the second mounting slot. The connecting portion 71b defines a receiving cavity opening toward the second mounting slot, and the connecting rod 52 is movably mounted within the receiving cavity. When the grip assembly 5 is moved relative to the handle body 1, the fixed portion 71a remains fixed to the operating handle 51. The connecting portion 71b is located between the operating handle 51 and the handle body 1 and can be squeezed and deformed. The entire grip assembly 5 is encased in the second waterproof cover 71, preventing water from entering the connection between the grip assembly 5 and the handle body 1.
[0065] Similarly, the second waterproof assembly 7 also includes a second waterproof seat 72, which is a closed ring along the circumferential direction and is fitted in the second mounting groove. The outer peripheral edge of the second waterproof cover 71 is clamped between the second waterproof seat 72 and the circumferential groove wall of the second mounting groove.
