Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an ultrasonic surgical scalpel used in prostate surgery. Background Technology

[0002] The application of ultrasound in surgery typically involves converting and transmitting ultrasonic energy into biological tissue. The resulting mechanical vibration and thermal effect cause the hydrogen bonds in tissue proteins to break, leading to protein denaturation and coagulation. In particular, the mechanical and thermal energy generated is used to perform operations such as coagulation, hemostasis, and cutting of tissues. Ultrasonic scalpels used for the prostate can be inserted into the patient's urethra, allowing the cutting area of ​​the ultrasonic scalpel to act on the patient's prostate for surgical procedures.

[0003] The ultrasound surgical observation equipment used in prostate ultrasound surgery is an optical microscope. The connection between the optical microscope and the ultrasound surgery is relatively large, but the surgical space is small during the operation, especially when it is used in prostate ultrasound surgery. The large connection makes it difficult for the operator to maintain balance during the operation, and the lens is easily contaminated by the patient's blood, making it difficult for the operator to observe the surgical site. Utility Model Content

The observation scope of the ultrasonic scalpel has a smaller volume, and this invention provides a novel ultrasonic scalpel structure adapted to the observation scope, which greatly reduces the overall weight of the scalpel, reduces the difficulty of operation for the operator, and allows the observation scope to be cleaned during the operation, thus making it easier for the operator to observe the patient's surgical site.

[0005] This utility model provides an ultrasonic scalpel for prostate surgery, comprising: a sliding scalpel holder having a sliding groove extending along a first direction; a cutting assembly having a cutting shank, a portion of which is accommodated within the sliding groove and is slidable relative to the sliding scalpel holder along the first direction; an observation mirror fixed to the sliding scalpel holder; and a cleaning tubing fixed to the sliding scalpel holder, the cleaning tubing being used to rinse the surgical site and the observation mirror.

[0008] In some embodiments, the sliding blade holder further includes: a blade holder body; a cutting blade sleeve fixedly connected to the blade holder body, wherein the sliding groove passes through the blade holder body and the cutting blade sleeve; wherein the cutting blade sleeve is sleeved on the outside of the blade bar to separate the blade bar from the cleaning pipeline.

[0009] In some embodiments, the observation mirror includes: an electronic lens; a transmission line fixedly connected to the electronic lens; wherein the sliding blade holder further includes: an electronic lens sleeve located inside the cleaning pipeline and sleeved outside the transmission line, the electronic lens being located inside the electronic lens sleeve and the end of the electronic lens being adjacent to the internal space of the cleaning pipeline.

[0010] In some embodiments, the ultrasonic scalpel further includes a moving block, which is sleeved on the outside of the scalpel shaft and axially fixed to the scalpel shaft; wherein the moving block has a first handle, the sliding scalpel holder has a second handle, and the first handle and the second handle are spaced apart in the first direction for driving the moving block and the scalpel shaft to slide relative to the sliding scalpel holder in the first direction.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The specific technical features described in the various embodiments in the detailed implementation can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0026] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0027] Additionally, it should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate any similarity or connection between them. It should be understood that the directional descriptions such as "above," "below," "inside," and "outside" refer to the orientation under normal use conditions.

[0028] In the following specific embodiments, the vibration frequency of the ultrasonic scalpel used in prostate surgery can be any frequency that meets the surgical requirements. It can be an ultrasonic scalpel with a low vibration frequency or a radiofrequency scalpel with a high vibration frequency. The structure and function of the ultrasonic scalpel used in prostate surgery are illustrated below with reference to various embodiments.

[0029] In some embodiments, such as Figure 1As shown, the ultrasonic scalpel for prostate surgery (hereinafter referred to as the ultrasonic scalpel) includes: a sliding scalpel holder 10, a cutting assembly 20, an observation mirror 30, and a cleaning tubing 40. The cutting assembly 20 includes a blade 21, which can generate ultrasonic vibrations to have a cutting function. The sliding scalpel holder 10 has a direction along a first direction (the first direction is as follows). Figure 1 (As shown by the middle arrow) The sliding groove extends, and the blade shank 21 is partially accommodated in the sliding groove and can slide relative to the sliding blade holder 10 in the first direction. During the sliding process of the blade shank 21 relative to the sliding groove, the end of the blade shank 21 can contact the patient's lesion to remove the lesion. During use, the operator holds the sliding blade holder 10 to control the position of the blade shank 21. After the blade shank 21 moves to the target position, the lesion of the patient is removed by sliding the blade shank along the first direction.

[0030] The observation scope 30 is fixed to the sliding blade holder 10 and can be inserted into the patient's urethra along with the blade 21, reaching the vicinity of the surgical site. The operator can view the patient's surgical site through the observation scope 30 to determine whether the blade 21 has reached the target position or to confirm whether the patient's lesion has been completely removed. Due to the confined space of the surgical site, the patient's blood may cover the lens of the observation scope 30 and the surgical site during the resection process, making it inconvenient for the operator to observe. Therefore, a cleaning structure is needed to clean the lens of the observation scope 30 and the surgical site. The observation scope 30 can be any structure capable of observing the tubed lesion. For example, the observation scope 30 can be an optical microscope or an electron microscope.

[0031] The cleaning tubing 40 is fixed to the sliding blade 10, and its outlet can enter the urethra along with the blade handle. This allows the outlet of the cleaning tubing 40 to be located near the surgical site and the lens of the observation mirror 30. The water flow from the cleaning tubing 40 can rinse away blood and water covering the lens surface of the observation mirror 30, as well as blood and water covering the surgical site, making it easier for the operator to observe the patient's surgical site. The cleaning tubing 40 can be a rigid or flexible tube. The water source for the cleaning tubing 40 can be a water tank built into the ultrasonic scalpel or an external water source. It should be noted that the cleaning tubing 40 can clean the observation mirror 30 in any way. For example, the cleaning tubing 40 has an observation mirror nozzle for directly spraying water onto the observation mirror 30 to clean it. For example, the observation mirror 30 is located inside the cleaning tubing 40, and is cleaned while sterile water is output from the cleaning tubing 40.

[0032] This utility model provides an ultrasonic scalpel for prostate surgery. The ultrasonic scalpel includes a sliding blade holder with a sliding groove extending in a first direction, and a cutting component with a cutting shank that is accommodated in the sliding groove and can slide relative to the sliding blade holder in the first direction. The position of the cutting component can be controlled by the sliding blade holder, and the cutting component can be slid relative to the sliding blade holder to cut the patient's affected area. The ultrasonic scalpel also includes an observation mirror fixed to the sliding blade holder for the operator to observe the surgical site, and a cleaning pipeline fixed to the sliding blade holder for rinsing the observation mirror and the surgical site. Because the surgical site is small, the patient's blood may cover the lens of the observation mirror and the surgical site during the resection, making it inconvenient for the operator to observe. The cleaning pipeline outputs water to rinse the blood covering the surface of the observation mirror and the blood covering the patient's surgical site, making it easier for the operator to observe the surgical site.

[0033] Optionally, the observation mirror 30 is an electronic mirror. The electronic mirror is smaller than the optical mirror, and the connection structure between the electronic mirror and the ultrasonic scalpel is also smaller. This makes the ultrasonic scalpel more suitable for prostate ultrasound surgery in confined spaces, and also makes it easier for the operator to maintain the balance of the scalpel during the operation.

[0034] In some embodiments, such as Figure 1 As shown, the observation mirror 30 and the blade 21 are located inside the cleaning conduit 40, and the end of the blade 21 extends from the water outlet of the cleaning conduit 40. This means that by placing the observation mirror 30 inside the cleaning conduit 40, the observation mirror 30 inside the cleaning conduit 40 can be cleaned while sterile water is output from the cleaning conduit 40, without the need for an additional water nozzle facing the observation mirror 30. At the same time, the end of the blade 21 extends from the water outlet of the cleaning conduit 40. This means that the end of the blade 21 extending out of the cleaning conduit 40 is a cutting position. Extending this end from the water outlet of the cleaning conduit 40 allows the water outlet of the cleaning conduit 40 to be as close as possible to the cutting position, thereby achieving a better flushing effect on the blood and fluid at the surgical site.

[0035] In some embodiments, such as Figure 1As shown, the sliding scalpel holder 10 has a first water inlet 12, and the cleaning pipeline 40 has a second water inlet 43. Both the first water inlet 12 and the second water inlet 43 are connected to the outlet of the cleaning pipeline 40. It can be understood that one of the two water inlets is used as the inlet and the other water inlet is used as the outlet, thus forming a main pipe between the two water inlets, and the cleaning pipeline 40 is used as a branch pipe. Thus, most of the external water input flows into and out of the ultrasonic scalpel through the main pipe. At the same time, a small amount of sterile water can flow into the branch pipe and be output to the patient's surgical site through the outlet of the cleaning pipeline 40. This allows most of the water pressure from the external water source to be discharged through the main pipe, thereby greatly reducing the water pressure of the sterile water output from the outlet and reducing the possibility of excessive water pressure causing damage to the patient's surgical site.

[0036] Optional, such as Figure 1 As shown, the cleaning pipeline 40 is fixedly connected to the sliding blade holder 10 via the first locking block 44, and the first locking block 44 can seal the gap between the cleaning pipeline 40 and the sliding blade holder 10, thereby reducing the risk of sterile water leaking from the gap between the cleaning pipeline 40 and the sliding blade holder 10 when the sterile water in the sliding blade holder 10 flows into the cleaning pipeline 40.

[0037] In some embodiments, combined with Figure 1 and Figure 2 The sliding tool holder 10 also includes a tool holder body 13 and a cutting tool tube sleeve 14. The tool holder body 13 is the main part of the tool holder 10, and the operator can control the position of the cutting tool 21 through the tool holder body 13. The cutting tool tube sleeve 14 is fixedly connected to the tool holder body 13, and a sliding groove passes through the tool holder body 13 and the cutting tool tube sleeve 14. That is, the tool holder body 13 has a part of the sliding groove, and the cutting tool tube sleeve 14 has another part of the sliding groove, and the two parts are connected. Part of the cutting tool 21 is located between the tool holder body 13 and the cutting tool tube sleeve 14. The cutting blade sleeve 14 is located outside the blade shank 21 and inside the cleaning pipe 40. This allows the end of the blade shank 21 to extend from the outlet of the cleaning pipe 40 while protecting the blade shank 21. This isolates the part of the blade shank 21 that does not participate in cutting from the sterile water in the cleaning pipe 40, keeping this part dry. This reduces the impact of the vibration of the blade shank 21 on the sterile water in the cleaning pipe 40 and extends the service life of the blade shank 21.

[0038] In some embodiments, such as Figure 3As shown, the observation mirror 30 includes an electronic lens 31 and a transmission line 32. The electronic lens 31 is used to acquire images of the patient's surgical site and convert these images into electrical signals. The transmission line 32 is fixedly connected to the electronic lens 31, enabling the output of these electrical signals. After the electrical signals are output to the ultrasound host in the operating room, the ultrasound host converts the signals into images and displays them on its screen, allowing the operator to observe the images of the surgical site. This is achieved by combining... Figures 1 to 3 The sliding scalpel holder 10 also includes an electron endoscope sleeve 15, which is fitted outside the transmission line 32 and located inside the cleaning line 40. Simultaneously, the electron lens 31 is located inside the electron endoscope sleeve 15, with its end adjacent to the internal space of the cleaning line 40. This can be understood as the end of the electron lens 31 serving as a transparent protective cover for the lens. Light from the surgical site can enter the interior of the electron lens 31 through this transparent protective cover. The photosensitive chip inside the electron lens 31 can convert the light into an electrical signal and transmit the electrical signal to the transmission line. 32, that is, except for the end of the electronic lens 31, the rest of the observation lens 30 is an electronic component. By placing the non-end of the electronic lens 31 and the transmission line 32 inside the electronic lens tube 15, the electronic lens tube 15 can protect the electronic components of the observation lens 30. At the same time, by placing the end of the electronic lens 31 at the end of the electronic lens tube 15 and adjacent to the internal space of the cleaning pipeline 40, the sterile water in the cleaning pipeline 40 can clean the transparent protective cover of the electronic lens, thereby removing the blood adhering to the transparent protective cover.

[0039] Optional, combined Figure 3 and Figure 4 The observation mirror 30 also includes a control board 33 and a transmission optical fiber 34. The transmission line 32 is fixedly connected to the control board 33, and the transmission optical fiber 34 is fixedly connected to the control board 33. The control board 33 is used to convert the electrical signal in the transmission line 32 into an optical signal, and the transmission optical fiber 34 is used to transmit the optical signal to the ultrasound host in the operating room. Optionally, the scalpel body 13 includes a receiving member 131 and a cover plate 132. The receiving member 131 has a circuit board cavity 133 with an opening. The cover plate 132 is detachably connected to the receiving member 131 and is used to cover the opening of the circuit board cavity 133. The control board 33 is located inside the circuit board cavity 133. Meanwhile, the receiving member 131 has a through hole communicating with the circuit board cavity 133, and the transmission optical fiber 34 can extend out of the circuit board cavity 133 through the through hole. Optionally, the surface of the cover plate 132 has an operating handle 134, which facilitates the installation or removal of the cover plate 132.

[0040] In some embodiments, such as Figure 5As shown, the ultrasonic scalpel also includes a moving block 50, which is sleeved on the outside of the scalpel handle 21 and axially fixed to the scalpel handle 21. That is, the moving block 50 restricts the axial sliding between the scalpel handle 21 and the moving block 50. The moving block 50 moves along a first direction (the first direction is as follows...). Figure 5 (As indicated by the middle arrow) When sliding, the moving block 50 can drive the blade 21 to slide relative to the sliding blade holder 10. The moving block 50 has a first handle 51, and the sliding blade holder 10 has a second handle 16. The first handle 51 and the second handle 16 are spaced apart in a first direction. The operator can drive the moving block 50 to slide relative to the sliding blade holder 10 in the first direction using the first handle 51 and the second handle 16, thereby driving the blade 21 to slide relative to the sliding blade holder 10 in the first direction, and thus enabling the blade 21 to remove the patient's lesion. Optionally, the first handle 51 and the second handle 16 can be on the same side of the ultrasonic scalpel, allowing the operator to slide the blade 21 relative to the sliding blade holder 10 using only one hand.

[0041] In some embodiments, such as Figure 5 As shown, the ultrasonic scalpel also includes an elastic element 60, which is located between the moving block 50 and the sliding blade holder 10. The two ends of the elastic element 60 abut against the sliding blade holder 10 and the moving block 50, respectively. When the moving block 50 is moved toward the sliding blade holder 10 by an external force, the elastic element 60 is compressed. After the external force is removed, the moving block 50 moves away from the sliding blade holder 10 under the elastic force of the elastic element 60 and returns to its original position before the external force was applied. It can be understood that the operator only needs to apply an external force to make the moving block 50 move toward the sliding blade holder 10, so that the end of the blade moves toward the patient's lesion to achieve cutting. After the external force is removed, the moving block 50 can automatically return to its original position, which is convenient for the operator's operation.

[0042] In some embodiments, such as Figure 5 As shown, the ultrasonic scalpel also includes a guide rod 70, and the end face of the sliding scalpel holder 10 facing the moving block 50 has a guide groove 17. The depth direction of the guide groove 17 is perpendicular to a first direction (as shown in the image). Figure 5 (As shown by the middle arrow) Parallel, the guide rod 70 is fixedly connected to the moving block 50, and part of the guide rod 70 is located in the guide groove 17. The guide rod 70 can guide the moving block 50. That is, the force between the guide rod 70 and the guide groove 17 restricts the movement of the moving block 50 except in the first direction. Moreover, when the moving block 50 moves relative to the sliding tool holder 10 in a direction other than the first direction, the bending moment generated by the movement is borne by the guide rod 70 and the bending moment will not be transmitted to the tool holder 21, reducing the risk of the tool holder 21 bending due to bending deformation and thus failing.

[0043] In some embodiments, such as Figure 6As shown, the cutting assembly also includes a transducer 22, which is detachably connected to the moving block 50. The transducer 22 is used to drive the ultrasonic vibration of the cutter bar 21, thereby giving the cutter bar 21 a stronger cutting ability. Moreover, since the transducer 22 is detachably connected to the moving block 50, the cutter bar 21 or the transducer 22 can be replaced according to the actual situation, which improves the versatility of the ultrasonic cutter.

[0044] In some embodiments, such as Figure 6 As shown, the cutting assembly 20 also includes a rotary motor 23, which is detachably connected to the motion block 50. The rotary motor 23 can drive the blade 21 to rotate. Depending on the cutting requirements, the blade 21 can slide only along the first direction, or the rotary motor 23 can be turned on to rotate around the first direction while the blade 21 slides along the first direction. Moreover, since the rotary motor 23 is detachably connected to the motion block 50, the rotary motor 23 can be removed when it is determined that the rotation function of the blade 21 is not needed, thereby reducing the weight of the ultrasonic cutter.

[0045] This utility model embodiment also provides a prostate surgery device, which includes an ultrasonic scalpel and an ultrasonic main unit. The ultrasonic scalpel includes an inlet / outlet water pipe holder, a blade retraction holder, and an ultrasonic resection blade. A water diversion pipe is welded to the main body of the inlet / outlet water pipe holder. Inlet / outlet water connectors are threaded onto the main body of the inlet / outlet water pipe holder. A locking block is threaded onto the main body of the inlet / outlet water pipe holder, assembling the inlet / outlet water pipe holder. An electron endoscope sleeve and an ultrasonic resection blade sleeve are welded together, then installed and welded onto the main body of the retraction holder. Inlet / outlet water connectors are threaded onto the main body of the retraction holder. A front handle is fixed to the main body of the retraction holder with screws. A spring is placed in a hole at the rear end of the main body of the retraction holder. A guide rod passes through a hole on the moving block and is threaded onto the main body of the retraction holder. A locking block is threaded onto the moving block, assembling the blade retraction holder. The blade moves back and forth, the blade holder inserts into the inlet and outlet water pipes to form a water path, and the locking block is twisted to lock the two components. The ultrasonic resection blade is inserted into the blade holder, moves back and forth, and the locking block is twisted to lock the two components. The ultrasonic resection blade and the electron microscope are connected to the ultrasonic host via a cable.

[0046] Among them, the design of the electronic mirror on the blade holder through the front and rear movement of the blade greatly reduces the overall weight of the blade, reduces the difficulty of operation for the operator, and reduces the manufacturing cost of the blade. At the same time, through the independent design of the ultrasonic resection blade and the blade holder, the blade holder can be matched with different types of ultrasonic resection blades to adapt to patients in different conditions, giving the ultrasonic resection blade more operability.

[0047] The principle of this application: A prostate ultrasound surgical device, in which a cleaning pipe 40 is welded to the inlet / outlet water pipe holder body 13, a first water inlet 12 and a second water inlet 43 are threaded onto the inlet / outlet water pipe holder body 13, and a first locking block 44 is threaded onto the inlet / outlet water pipe holder body 13 to assemble the inlet / outlet water pipe holder. An electron microscope sleeve 15 and a cutting blade sleeve 14 are welded together, then mounted on a sliding holder 10 and welded together. The first water inlet 12 and the second water inlet 43 are threaded onto the holder body 13, a first handle 15 is screwed onto the holder body 13, an elastic element 60 is placed in the rear end hole of the sliding holder 10, a guide rod 70 passes through a hole in the moving block 50 and is threaded onto the holder body 13, and a second locking block is threaded onto the moving block 50 to assemble the sliding holder 10. The sliding blade holder 10 is inserted into the inlet / outlet water pipe to form a water channel, and the first locking block 44 is twisted to lock the two components. The blade rod 21 is inserted into the sliding blade holder 10, and the second locking block is twisted to lock the two components. The cutting component 20 and the electronic lens 31 are connected to the ultrasound host via a cable. The resection surgery is achieved by pressing the motion block 50, which moves back and forth on the guide rod 70 to drive the cutting component 20. During the surgery, this prostate ultrasound surgical device is inserted into the patient's urethra until it reaches the prostate lesion. The patient's lesion and the blade can be observed through the electronic endoscope. Pressing the motion block 50 moves the blade to perform the resection surgery.
