[0059] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0060] To solve the related technical problems, as shown in Figure 1a and Figure 2 The utility model embodiment provides a kind of installation protection pipe for ultrasonic probe 4, comprising:

[0061] Protect long pipe 1, first installation passage 100 is arranged in protection long pipe 1, first installation passage 100 is used to pass through ultrasonic probe 4, first sensor protection pipe 2 is fixedly arranged in protection long pipe 1, first sliding passage 200 is established in first sensor protection pipe 2, and first sliding passage 200 is used to accommodate sensor wire harness;

[0062] Handle fixed component 3, second installation passage 38 is arranged in handle fixed component 3, handle fixed component 3 is fixedly arranged in the end of protection long pipe 1, second installation passage 38 is communicated with first installation passage 100, and second installation passage 38 is used for the front end of ultrasonic probe 4 to pass through and accommodate probe handle end 40 of fixed ultrasonic probe 4.

[0063] In the embodiment, installation protection pipe is mainly used to install ultrasonic probe 4 and electromagnetic navigation sensor together. Ultrasonic probe 4 includes probe handle end 40, long strip-shaped insertion pipe and ultrasonic wave emission part located at the front end of insertion pipe. Electromagnetic navigation sensor needs to be installed to the back of ultrasonic wave emission part. Electromagnetic navigation sensor and ultrasonic wave emission part can be connected by specific buckle component or adhesive, etc., and the embodiment does not limit it here.

[0064] As shown in Figure 10As shown, in an embodiment, the electromagnetic navigation sensor can be connected with the ultrasonic wave emitting part through a specific buckle assembly, which includes a probe buckle 11, a clamping groove and a clamping piece 12. The probe buckle 11 can be sleeved on the ultrasonic wave emitting part, and the probe buckle 11 has an opening for avoiding the emitting window of the ultrasonic wave emitting part. The clamping groove is installed on the inner side of the probe buckle 11, and the electromagnetic navigation sensor is installed on the clamping groove and adheres to the outer side of the ultrasonic wave emitting part under the action of the probe buckle 11. The clamping piece 12 can be sleeved on the rear end of the probe buckle 11 to tightly hold the probe buckle 11 on the ultrasonic wave emitting part. It should be noted that the structure of the buckle assembly in the embodiment is not limited, and other structures of the buckle assembly can also be used by those skilled in the art.

[0065] Since the electromagnetic navigation sensor needs to be connected with a wire harness for use, the arrangement of the sensor wire harness also needs to be considered. As shown in the figure, Figure 1a As shown in the embodiment, the installation protection pipe mainly includes a protection long pipe 1, a first sensor protection pipe 2 and a handle fixing assembly 3. The protection long pipe 1 is a long strip-shaped tubular structure with a hollow cavity to form a first installation channel 100 for the insertion of an ultrasonic probe 4. The handle fixing assembly 3 is fixed at the rear end of the protection long pipe 1, and the handle fixing assembly 3 is provided with a second installation channel 38 in communication with the first installation channel 100. As shown in the figure, Figure 2 As shown in the figure, the insertion tube of the ultrasonic probe 4 is loaded into the second installation channel 38 and after passing through the first installation channel 100, the ultrasonic wave emitting part at the front end of the insertion tube passes out of the front end of the first installation channel 100. At this time, the probe handle end 40 of the ultrasonic probe 4 is located in the second installation channel 38 of the handle fixing assembly 3, and the probe handle end 40 of the ultrasonic probe 4 is fixed by the handle fixing assembly 3. In an embodiment, the probe handle end 40 of the ultrasonic probe 4 can be fixed by buckling or screwing, and the embodiment does not limit the fixing method.

[0066] After the ultrasonic probe 4 is installed in the installation protection pipe, the electromagnetic navigation sensor also needs to be installed in the installation protection pipe. As shown in the figure, Figure 1a As shown in the embodiment, the first sensor protection pipe 2 is arranged in the protection long pipe 1, and the first sensor protection pipe 2 is a long strip-shaped tubular structure with a hollow cavity to form a first sliding channel 200. The first sliding channel 200 has an open structure at both ends. The sensor wire harness of the electromagnetic navigation sensor can pass into the first sliding channel 200 from the rear end of the first sliding channel 200 and extend to the front of the first sliding channel 200, and the sensor wire harness is at least partially located in the first sliding channel 200.

[0067] Furthermore, the front end of the first sensor protection tube 2 extends beyond the long protection tube 1 to form an extension section 201. This extension section 201 is flexible and corresponds to the bend of the ultrasound probe 4. This flexible extension section 201 better protects the portion of the sensor harness that follows the bend of the ultrasound probe 4. If an additional protective tube is attached to the sensor harness, the flexible extension section 201 can also protect the curved portion of the protective tube.

[0068] On the one hand, the utility model establishes an installation channel for the ultrasonic probe 4 through the protective long tube 1 and the handle fixing assembly 3, and establishes an installation channel for the electromagnetic navigation sensor through the first sensor protection tube 2, thereby facilitating the installation and combination of the ultrasonic probe 4 and the electromagnetic navigation sensor, thereby solving the problem of inconvenient installation and combination of the navigation device and the ultrasonic probe 4 in the related art;

[0069] On the other hand, after installation, the protective long tube 1 can protect the ultrasonic probe 4, and the first sensor protection tube 2 can also protect the sensor harness, thereby avoiding damage during use and improving safety.

[0070] In one embodiment of the ultrasound probe 4, the ultrasonic emitting portion is bendable relative to the insertion tube, with the bending process controlled by a wrench on the probe handle 40. Because the electromagnetic navigation sensor is fixed to the ultrasonic emitting portion, it also moves with the ultrasonic emitting portion. Therefore, the sensor harness connected to the electromagnetic navigation sensor must be able to slide within the first sliding channel 200.

[0071] For this reason, Figure 1a and Figure 3 As shown, in this embodiment, a slide groove 34 is provided on the handle fixing assembly 3 , a slider 35 is provided in the slide groove 34 , the slide groove 34 is communicated with the first sliding channel 200 , and the slider 35 is used to fix the sensor harness.

[0072] Specifically, in this embodiment, the electromagnetic navigation sensor is inserted through the rear end of the first sliding channel 200, and the sensor wiring harness is routed within the first sliding channel 200. Once the electromagnetic navigation sensor is installed in the desired position (i.e., the length extending out of the first sliding channel 200 meets the design value), the sensor wiring harness is installed within the chute 34 and secured to the slider 35. The distal end of the sensor wiring harness then extends rearward to connect to the device. As the electromagnetic navigation sensor moves with the ultrasonic transmitter, the sensor wiring harness drives the slider 35 within the chute 34. The slider 35 cooperates with the chute 34 to constrain the sensor wiring harness and support its movement. Furthermore, in this embodiment, after the sensor wiring harness is positioned within the handle fixing assembly 3 of the tooling, the entire sensor wiring harness is concealed within the tooling, protecting it from damage during use. In this utility model, the sensor wiring harness may comprise only the wiring harness connected to the electromagnetic navigation sensor, or it may comprise the wiring harness connected to the electromagnetic navigation sensor and a protective sheath or tube attached to the wiring harness.

[0073] The handle fixing assembly 3 is used by doctors to operate the ultrasound probe 4 by hand, so it has a length and shape that meet the operation requirements. Since the movement of the electromagnetic navigation sensor is only the bending and deformation of the ultrasonic transmitter relative to the ultrasound probe within a certain angle, the sliding stroke of the follower slider 35 in the slide groove 34 is relatively short, that is, the length of the slide groove 34 does not need to be set too long. On this basis, in order to ensure the sliding of the sensor harness relative to the handle fixing assembly 3, as shown in FIG. Figure 5 As shown, in this embodiment, a second sliding channel 36 is provided on the handle fixing assembly 3 , and both ends of the second sliding channel 36 are communicated with the first sliding channel 200 and the sliding groove 34 respectively.

[0074] In other words, in this embodiment, two channels are provided on the handle fixing assembly 3, one of which is the second sliding channel 36 and the other is the slide groove 34. The second sliding channel 36 only needs to accommodate the sensor harness and slide with the sensor harness, while the slide groove 34 needs to provide a sliding track for the slider 35. Figure 5 As shown, in this embodiment, the sliding groove 34 can be opened at a position close to the end of the handle fixing assembly 3.

[0075] After setting the second sliding channel 36, the electromagnetic navigation sensor needs to be inserted from the rear end of the second sliding channel 36 during installation, and then pass through the first sliding channel 200 and out from the front end of the first sliding channel 200. The sensor wiring harness is similarly arranged on the slide groove 34 and the slider 35.

[0076] On the basis of providing the chute 34, as Figure 8As shown, in order to better protect the sensor harness, the slide groove 34 and the slider 35 , a snap-fit ​​cover 37 is provided on the handle fixing assembly 3 in this embodiment, and the snap-fit ​​cover 37 is snap-fitted and fixed on the slide groove 34 .

[0077] Specifically, in this embodiment, the snap-on cover 37 is snap-fastened to the handle fixing assembly 3, covering the slide groove 34 to provide protection. The snap-on cover 37 can be configured as a flip-top structure, with one side hinged to the handle fixing assembly 3 and the other side secured to the handle fixing assembly 3 by a snap connection or screws. Alternatively, the snap-on cover 37 can be configured as a separate cover-like structure, with snaps provided at the edges of the snap-on cover 37, which snap-on connects to the handle fixing assembly 3.

[0078] The handle fixing assembly 3 is used as a structure for fixing the probe handle end 40 of the ultrasound probe 4. Figure 1a and Figure 2 As shown, in one embodiment, the handle fixing assembly 3 is fixed by holding the probe handle end 40 of the ultrasound probe 4. In this embodiment, the handle fixing assembly 3 includes a connecting member 31, a first clamping fixing member 32 and a second clamping fixing member 33;

[0079] The connecting member 31 is fixedly sleeved on the end of the protective long tube 1, and the first clamping member 32 and the second clamping member 33 are arranged opposite to each other. The first clamping member 32 and the second clamping member 33 are used to clamp and fix the probe handle end 40 of the ultrasonic probe 4;

[0080] The sliding groove 34 is provided on the first clamping fixture 32 or the second clamping fixture 33 .

[0081] Specifically, it should be noted that the handle fixing assembly 3 includes a first clamping fixture 32 and a second clamping fixture 33 that are relatively distributed, and a connecting member 31 that can be fixed to the rear end of the protective long tube 1. The connecting member 31 can be an annular structure that is sleeved and fixed to the rear end of the protective long tube 1, or it can be at least two connecting blocks fixed to the rear end of the protective long tube 1. A second installation channel 38 is formed between the first clamping fixture 32 and the second clamping fixture 33. When installing the ultrasonic probe 4, the first clamping fixture 32 and the second clamping fixture 33 are first separated by a distance to make room for installation. After the ultrasonic probe 4 is installed, the first clamping fixture 32 and the second clamping fixture 33 are adjusted to tightly hold the probe handle end 40 of the ultrasonic probe 4.

[0082] In one embodiment of the first clamping fixture 32 and the second clamping fixture 33, the first clamping fixture 32 and the second clamping fixture 33 can be hinged to the connecting member 31, thereby enabling opening or clamping by rotation. In another embodiment, the first clamping fixture 32 and the second clamping fixture 33 can be slidably connected to the connecting member 31 in a radial direction, thereby enabling opening or clamping by linear sliding.

[0083] In this embodiment, the slide groove 34 for supporting the sliding of the sensor harness can be selectively arranged on the first clamping fixture 32 or the second clamping fixture 33, and this is not limited in this embodiment. Furthermore, to enhance the tightness with which the two clamping fixtures grip the probe handle 40 of the ultrasound probe 4, the inner side profiles of the first clamping fixture 32 and the second clamping fixture 33 in this embodiment match the surface profile of the probe handle 40 of the ultrasound probe 4.

[0084] In terms of distribution, the first clamping fixture 32 can be located above the second clamping fixture 33, so when holding the doctor, the first clamping fixture 32 contacts the doctor's palm. Since the first clamping fixture 32 and the second clamping fixture 33 are both movably connected to the connecting member 31, it is obvious that the connection structure set at the connection position will affect the doctor's grip. For this reason, Figure 1a As shown, in this embodiment, the first clamping fixture 32 is divided into two sections, specifically a fixed section 320 and a movable section 321, according to the doctor's gripping area. The first end of the fixed section 320 is fixedly connected to the upper side of the connector 31 (when the connector 31 is an annular structure, the upper side here refers to the upper area of ​​the end surface of the connector 31), and the rear end is movably connected to the movable section 321. After the fixed section 320 and the connector 31 are fixedly connected, the two can be connected in an integral manner or by end-face welding, so that the connection position of the fixed section 320 and the connector 31 is relatively smooth, thereby facilitating operation when the fixed section 320 is used as the doctor's gripping section.

[0085] Furthermore, it should be noted that the length of the fixing section 320 is not only determined by the physician's gripping area but also by the structure of the probe handle 40 of the ultrasound probe 4. In one embodiment, the probe handle 40 of the ultrasound probe 4 has a protrusion in the middle. Since the fixing section 320 is a fixed structure, the rear end of the fixing section 320 cannot extend beyond the apex of the protrusion on the probe handle 40 to ensure proper installation. If the probe handle 40 of the ultrasound probe 4 has other structures, the fixing section 320 also needs to be adjusted based on the structural features of the probe handle 40. This is not discussed in detail in this embodiment.

[0086] In this embodiment, in order to make the entire structure more compact and to facilitate clamping and fixing the probe handle end 40 of the ultrasonic probe 4, a rotational motion is adopted in this embodiment. Figure 1a As shown, in this embodiment, the second end of the fixed section 320 is hinged to the first end of the movable section 321; the first end of the second clamping fixture 33 is hinged to the lower side of the connecting member 31 (when the connecting member 31 is a ring structure, the lower side here refers to the lower area of ​​the end face of the connecting member 31).

[0087] During installation, the movable section 321 can be rotated upward and the second clamping fixture 33 can be rotated downward to make way for the installation channel of the ultrasonic probe 4. After installation, the movable section 321 can be rotated downward to fit the upper area of ​​the probe handle end 40 of the ultrasonic probe 4, and the second clamping fixture 33 can be rotated upward to fit the lower area of ​​the probe handle end 40. Figure 3 As shown, to facilitate gripping the probe handle 40, in this embodiment, the second end of the movable segment 321 and the second end of the second clamping fixture 33 are detachably fixedly connected via a locking member 6. In this embodiment, the locking member 6 connects the movable segment 321 and the second end of the second clamping fixture 33. In one embodiment, the locking member 6 can be a latch, a locking screw, or a snap-fit ​​structure, etc., which is not limited in this embodiment.

[0088] After the first clamping fixture 32 is divided into a fixed section 320 and a movable section 321, the slide 34 is provided on the movable section 321. Figure 5 As shown, the second sliding channel 36 opened on the first clamping fixing member 32 includes a first sliding section 361, a second sliding section 362 and a third sliding section 363. The first sliding section 361 is located on the connecting member 31, the second sliding section 362 is located on the fixed section 320, and the third sliding section 363 is located on the movable section 321.

[0089] In this embodiment, the front portion of the movable section 321 has a third sliding section 363, and the rear portion of the movable section 321 has a slide groove 34, which communicates with the third sliding section 363. The distal end of the first sensor protection tube 2 extends through the first sliding section 361 and the second sliding section 362 to the third sliding section 363. The distal end of the first sensor protection tube 2 can optionally extend into the slide groove 34 or not. Because the distal end of the first sensor protection tube 2 extends into the movable section 321 through the fixed section 320, the movable section 321 must rotate open relative to the fixed section 320 when the ultrasound probe 4 is installed. To prevent excessive rotation from causing damage to the first sensor protection tube 2, the maximum rotation angle of the movable section 321 is limited. In one embodiment, when the movable section 321 is at its maximum external rotation angle, the opening and closing angle between the second sliding section 362 and the third sliding section 363 is less than 20°.

[0090] In one embodiment of limiting the rotation angle, a limit lever is provided on the fixed segment 320, located in the rotation direction of the movable segment 321. When the movable segment 321 rotates upward until it contacts the limit lever, the movable segment 321 cannot rotate further, thereby limiting the maximum rotation angle of the movable segment 321. In another embodiment, the rotation angle can be limited by adjusting the hinged connection between the movable segment 321 and the fixed segment 320, which is not described in detail in this embodiment.

[0091] like Figure 8 and Figure 9 As shown, in order to achieve locking of the first clamping fixture 32 and the second clamping fixture 33, the locking member 6 in this embodiment includes a first clip 60 and a second clip 61. The first clip 60 is fixed to the second end of the movable section 321, and the second clip 61 is fixed to the second end of the second clamping fixture 33. The first clip 60 and the second clip 61 are clipped together.

[0092] Specifically, in this embodiment, after the first clamping fixture 32 and the second clamping fixture 33 are rotated and tightly embraced on the probe handle end 40 of the ultrasound probe 4, the first clip 60 and the second clip 61 can be operated to snap together to lock the first clamping fixture 32 and the second clamping fixture 33. In one embodiment of the first clip 60 and the second clip 61, at least one of the first clip 60 and the second clip 61 is configured to be elastic, and due to its own elasticity, it can automatically snap together during the pressing process.

[0093] Specifically, buckle grooves are provided on both sides of the first buckle 60, and the second buckle 61 includes a base 611, a torsion spring and a clamping strip 610. The clamping strip 610 is provided in two and is hinged on both sides of the base 611 through a rotating shaft. The torsion spring is sleeved on the rotating shaft. The first end of the clamping strip 610 is provided with a clamping protrusion, and the second end of the clamping strip 610 is provided with a push handle 612. The buckle groove and the clamping protrusion are connected by a buckle.

[0094] In this embodiment, during the engagement of the first clamping fixture 32 and the second clamping fixture 33, the lower end of the first buckle 60 abuts against the upper end of the clip 610. As the first clamping fixture 32 and the second clamping fixture 33 are further engaged, the first buckle 60 pushes the clip 610 to rotate outward, compressing the torsion spring. When the buckle groove on the first buckle 60 aligns with the engaging protrusion on the clip 610, the first clamping fixture 32 and the second clamping fixture 33 are firmly secured to the probe handle 40 of the ultrasound probe 4. Simultaneously, the clip 610 rotates inward under the elastic force of the torsion spring, engaging the buckle groove and the engaging protrusion, thereby completing the locking process.

[0095] To facilitate rotation of the clamping bar 610 during the locking process, the first clamping bar 60 has an inclined surface at the bottom end of the first clamping bar 60 that contacts the clamping bar 610, and an inclined surface at the top end of the clamping bar 610 that contacts the first clamping bar 60. Force transmission is achieved through the cooperation of these two inclined surfaces.

[0096] like Figure 9 As shown, to facilitate rotation of the clamping strip 610 during disassembly, a push handle 612 is provided at the lower end of the clamping strip 610 in this embodiment, and the push handle 612 is perpendicular to the end surface of the clamping strip 610. In one embodiment, to facilitate installation of the clamping strip 610 and the torsion spring, the base 611 is configured as a U-shaped base with an arcuate groove provided therein. The two clamping strips 610 are configured as arcs and are installed in the arcuate groove via a rotating shaft. The torsion spring is sleeved on the rotating shaft and located in the arcuate groove, and the clamping strip 610 rotates within a certain angle range within the arcuate groove.

[0097] After being fixedly connected to the slider 35, the sensor harness must pass through the through-hole at the rear end of the first clamping fixture 32. As the ultrasonic emitting portion of the ultrasonic probe 4 bends, the electromagnetic navigation sensor moves synchronously, causing the sensor harness to drive the slider 35 within the chute 34 and pull the rear end of the sensor harness to move. Since the harness at the rear end of the first clamping fixture 32 inevitably bends during use, it is easily damaged during the pulling process. Therefore, to avoid damage, a certain amount of margin is provided within the chute 34 for the sensor harness. During movement of the electromagnetic navigation sensor, only the sensor harness within the chute 34 moves, while the harness at the rear end of the first clamping fixture 32 remains stationary.

[0098] To achieve this goal, Figures 3 to 5 As shown, in this embodiment, a winding spring 7 is further provided on the first clamping fixture 32. The winding spring 7 is located at the rear end of the slider 35. The front end of the winding spring 7 is fixedly connected to the slider 35, and the rear end of the winding spring 7 is fixed to the handle fixing assembly 3. The winding spring 7 is used to wind and constrain the sensor harness.

[0099] The handle fixing assembly 3 is provided with a fixing portion, which is located at the rear end of the winding spring 7 and is used to fix the sensor harness;

[0100] The maximum stretching amount of the winding spring 7 is greater than the maximum sliding stroke of the slider 35 in the sliding groove 34 .

[0101] Specifically, the winding spring 7 is a spring. After passing through the slider 35, the sensor wire harness is wound around the winding spring 7 in the direction of the winding spring 7's spiral. After being wound, the sensor wire harness passes through the first clamping fixture 32 and is simultaneously clamped and secured to the first clamping fixture 32 by a pressure plate or other structure. The front end of the winding spring 7 is fixedly connected to the slider 35, while the rear end is fixed to the first clamping fixture 32. As the slider 35 moves linearly within the chute 34, it stretches the winding spring 7.

[0102] First, when the ultrasonic emitting portion at the front end bends, the slider 35 slides in the chute 34 in a coordinated manner. At the same time, the slider 35 pulls the winding spring 7 to deform and gain elastic potential energy. When the ultrasonic emitting portion recovers, the winding spring 7 can pull the slider 35 back to its original position. Second, because the sensor harness is wound around the winding spring 7, when the winding spring 7 stretches, the sensor harness wound around the winding spring 7 also deforms. Since the maximum stretching of the winding spring 7 is greater than the maximum sliding stroke of the slider 35 in the chute 34, the maximum deformable amount of the sensor harness is also greater than the maximum sliding stroke of the slider 35. Therefore, during the sliding process of the slider 35, no pulling is generated on the rear end of the sensor harness.

[0103] like Figure 4 As shown, in order to reasonably utilize the space, the winding spring 7 in this embodiment is arranged in the slide groove 34, and the fixing part is a fixed card slot opened at the rear end of the slide groove 34. A fixing plate is detachably fixed on the fixed card slot, and the fixing plate is used to press the sensor harness into the fixed card slot.

[0104] Specifically, in this embodiment, the rear end of the sensor harness, after being spirally wound around the winding spring 7, extends through a fixed slot and out of a first clamping fixture 32. The portion of the sensor harness in the fixed slot is clamped and secured by a fixing plate. During movement of the electromagnetic navigation sensor, the portion of the sensor harness extending beyond the first clamping fixture 32 remains stationary, while only the portion wrapped around the winding spring 7 stretches as the spring stretches, thereby tracking the movement of the electromagnetic navigation sensor and completely preventing any pull on the external sensor harness.

[0105] Since the second end of the winding spring 7 needs to be fixed, in one embodiment, Figure 4 As shown, a fixing seat 8 is provided on the handle fixing assembly 3, and in particular, the fixing seat 8 can be provided on the first clamping fixing member 32. The fixing seat 8 is located in front of the fixing slot, and the rear end of the winding spring 7 is fixedly connected to the fixing seat 8; a wire passing groove 80 is provided on the fixing seat 8, and the wire passing groove 80 is used for the sensor harness to pass through.

[0106] Specifically, in this embodiment, the rear end of the sensor harness passes through a wire groove 80 and then through a fixed slot after being wound onto the winding spring 7. The fixed connection between the rear end of the winding spring 7 and the fixing base 8 can be achieved by welding, bonding, or a locking structure such as a locking screw, which is not limited in this embodiment.

[0107] In one embodiment, to facilitate securing the rear end of the winding spring 7, the fixing base 8 is provided with a spring insertion hole, located below the wire slot 80. The rear end of the winding spring 7 is inserted into the spring insertion hole and locked securely. Specifically, in this embodiment, a threaded hole is provided on the fixing base 8 along the radial direction of the spring insertion hole. A locking screw is threadedly connected within the threaded hole. The locking screw can press the rear end of the winding spring 7 into the spring insertion hole. Of course, those skilled in the art may also adopt other fixing methods, and the above description is not restrictive.

[0108] like Figure 4 As shown, in order to control the extension and contraction movement of the winding spring 7 within a set range, a guide post 81 is provided at the front end of the fixing base 8 in this embodiment, and the spiral portion of the winding spring 7 is sleeved on the guide post 81. The extension and contraction movement of the winding spring 7 are both carried out along the guide post 81, which can prevent the winding spring 7 from shifting during movement.

[0109] Based on the above embodiment, to reduce the inner diameter of the first sensor protection tube 2, the sensor wiring harness can be stripped. Specifically, the portion of the sensor wiring harness corresponding to the first sensor protection tube 2 can be stripped, thereby reducing the diameter of this portion of the sensor wiring harness, and thus reducing the required diameter of the first sensor protection tube 2. Similarly, the portion of the sensor wiring harness located within the second sliding channel 36, the chute 34, the slider 35, and the winding spring 7 can also be stripped. The portion of the sensor wiring harness secured to the rear end of the first clamping fixture 32 can remain stripped to improve structural strength.

[0110] In one embodiment, the sensor harness is directly passed through the first sliding channel 200 and the second sliding channel 36. Since the sensor harness will slide relative to the sliding channel, in order to better protect the harness, in another embodiment, as shown in FIG. Figure 7 As shown, the installation protection tube also includes a second sensor protection tube 10, which slides through the first sliding channel 200. A third installation channel is provided in the second sensor protection tube 10, and the third installation channel is used to install the electromagnetic navigation sensor.

[0111] In this embodiment, during installation, the electromagnetic navigation sensor is pre-inserted into the third mounting channel of the second sensor protection tube 10, with the front end of the electromagnetic navigation sensor extending out of the second sensor protection tube 10. The stripped sensor wiring harness is housed in the third mounting channel and secured to the second sensor protection tube 10 by adhesive. The electromagnetic navigation sensor and the second sensor protection tube 10 are then inserted together into the first sliding channel 200 of the first sensor protection tube 2. As the electromagnetic navigation sensor moves with the ultrasonic transmitter, the second sensor protection tube 10 slides linearly within the first mounting channel 100, providing protection for the sensor wiring harness.

[0112] like Figure 5 As shown, in one embodiment, the rear end of the first sensor protection tube 2 extends to near the middle of the third sliding section 363. The rear end of the second sensor protection tube 10 extends beyond the rear end of the first sensor protection tube 2, passes through the third sliding section 363, and into the slide groove 34, ultimately securing it to the slider 35. The stripped rear end of the sensor wiring harness extends beyond the rear end of the second sensor protection tube 10, passes through the slider 35, and is wound around the winding spring 7. The stripped portion of the sensor wiring harness passes through the first clamping fixture 32 and is secured thereto.

[0113] To facilitate the installation of the sensor harness on the slider 35, as shown in FIG. Figure 4 As shown, in this embodiment, a mounting groove 350 is provided on the slider 35 . The mounting groove 350 passes through the slider 35 along the sliding direction of the slider 35 . The mounting groove 350 is used to fix the sensor harness.

[0114] In one embodiment, the second sensor protection tube 10 needs to be installed on the slider 35, and the sensor wiring harness also needs to be installed on the slider 35. Since the diameter of the sensor wiring harness is smaller than the outer diameter of the second sensor protection tube 10, the installation groove 350 includes a first groove body 3500 and a second groove body 3501 arranged from front to back. The width of the first groove body 3500 is greater than the width of the second groove body 3501. The first groove body 3500 is used to accommodate the second sensor protection tube 10, and the second groove body 3501 is used to accommodate the sensor wiring harness and part of the spring wire of the winding spring 7.

[0115] When the rear end of the sensor harness passes through the second slot 3501 and is wound around the winding spring 7 , portions of the sensor harness located on the second slot 3501 and the winding spring 7 are partially removed.

[0116] Since the second sensor protection tube 10 will also bend when the ultrasonic emitting portion bends, in order to better protect the second sensor protection tube 10, as shown in FIG. Figure 1bAs shown, in this embodiment, the front end of the first sensor protection tube 2 extends out of the front end of the protection long tube 1 and forms an extension section 201. At least a portion of the extension section 201 is configured as a transition section 202, which is formed by cutting the extension section along a spiral line.

[0117] Specifically, in this embodiment, the front end of the second sensor protection tube 10 extends beyond the front end of the first sensor protection tube 2. A spiral transition section 202 is provided on the extension 201 of the first sensor protection tube 2 extending from the long protective tube 1. The transition section 202 is located at the bend point of the second sensor protection tube 10. In this embodiment, the transition section 202 is formed by cutting the extension section 201. This allows it to bend at any angle without breaking, thus protecting the second sensor protection tube 10 while preventing the extension section 201 of the first sensor protection tube 2 from breaking.

[0118] like Figure 6 As shown, to further protect the first sensor protection tube 2, the installation protection tube in this embodiment also includes a stent graft 9. The stent graft 9 is sleeved and fixed to the front end of the long protection tube 1, and the first sensor protection tube 2 is inserted into the stent graft 9. When the ultrasonic emitting portion bends back, the stent graft 9 prevents the first sensor protection tube 2 from separating from the bend, which could cause damage such as breakage. In this embodiment, the stent graft 9 can be a cardiovascular stent as known in the related art, and its specific structure is not limited in this embodiment.

[0119] In this embodiment, the length of the stent graft 9 should be such that the front end of the stent graft 9 is positioned over the curved portion of the ultrasound probe, causing the front end of the stent graft 9 to bend during bending. This positioning of the front end of the stent graft 9 over the curved portion allows the first sensor protection tube 2 to fit closely to the curved portion of the ultrasound probe, preventing breakage during bending. In this embodiment, the transition section 202 of the first sensor protection tube 2 can extend beyond the front end of the stent graft 9 or not. If it does extend beyond the front end of the stent graft 9, the extension should be kept within 3 mm.

[0120] To facilitate the installation of the stent graft 9 on the protective long tube 1, as shown in FIG. Figure 6 and Figure 7 As shown, the stent graft 9 in this embodiment includes a large diameter section 90 and a small diameter section 91 , and the large diameter section 90 is sleeved and fixed on the front end of the protective long tube 1 .

[0121] In another embodiment, in order to protect the first sensor protection tube 2 , the membrane support 9 can be replaced with a heat shrink tube or other tubular structure that has a certain supporting capacity and can shrink.

[0122] In one embodiment, the long protection tube 1 , the first sensor protection tube 2 , and the second sensor protection tube 10 are all made of biocompatible materials, such as nickel-titanium, or the long protection tube 1 is made of stainless steel.

[0123] According to another aspect of the present invention, Figure 10 As shown, an ultrasound probe 4 assembly is provided, comprising the aforementioned mounting protective tube, the ultrasound probe 4, a probe clip 11, a clamping member 12, a second sensor protection tube 10, and an electromagnetic navigation sensor. The electromagnetic navigation sensor passes through the second sensor protection tube 10, the sensor wiring harness is fixed within the second sensor protection tube 10, and the electromagnetic navigation sensor extends out of the front end of the second sensor protection tube 10. The ultrasound probe 4 is sleeved within the protective long tube 1, the ultrasonic emitting portion of the ultrasound probe 4 extends out of the front end of the protective long tube 1, and the probe handle end 40 of the ultrasound probe 4 is fixed within the handle fixing assembly 3. The second sensor protection tube 10 is slidably sleeved within the first sensor protection tube 2. The electromagnetic navigation sensor is attached to the ultrasonic emitting portion via the probe clip 11, and the clamping member 12 holds the probe clip 11 tightly and securely to the ultrasound probe 4.

[0124] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
