[0048] To solve related technical problems, such as Figure 1a and Figure 1bAs shown, the utility model embodiment provides a mounting tool for ultrasonic probe 4, including:

[0050] First sensor protection pipe 2, first sensor protection pipe 2 is fixed in mounting piece 11, and first sliding channel 200 is established in first sensor protection pipe 2, and first sliding channel 200 is used to accommodate sensor wire harness;

[0051] The front end of first sensor protection pipe 2 extends the front end of mounting piece 11 and forms extension section 201, and at least a portion of extension section 201 is arranged as transition section 202 formed by cutting extension section along helix, and transition section 202 corresponds with the bending of ultrasonic probe 4;

[0054] Mounting piece 11 is mainly used to install ultrasonic probe 4, and the specific structure of mounting piece 11 can be set according to the structure of ultrasonic probe 4.In an implementation manner, mounting piece 11 includes protection long pipe 1, and first installation channel 100 is arranged in protection long pipe 1, and first installation channel 100 is used to pass through ultrasonic probe 4.Handle fixing assembly 3 is installed at the rear end of mounting piece 11, and can fix probe handle end 40 of ultrasonic probe 4.First sensor protection pipe 2 is fixed on mounting piece 11, and specifically can be fixed on the inner side of protection long pipe 1, and of course in some implementation manners, it can also be fixed on the outer side of protection long pipe 1 or arranged on other structure type mounting piece 11, and the specific arrangement mode is not limited in the embodiment.

[0055] In an embodiment, the electromagnetic navigation sensor can be connected with the ultrasonic wave emitting part through a specific buckle assembly, which comprises a probe buckle, a clamping groove and a clamping piece. The probe buckle can be sleeved on the ultrasonic wave emitting part, and the probe buckle 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, and the electromagnetic navigation sensor is installed on the clamping groove and is attached to the outer side of the ultrasonic wave emitting part under the action of the probe buckle. The clamping piece can be sleeved on the rear end of the probe buckle to tightly hold the probe buckle 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.

[0056] After the ultrasonic probe 4 is installed to the installation tool, the electromagnetic navigation sensor needs to be installed. As shown in the figure, Figure 1a In the embodiment, the first sensor protection pipe 2 is arranged on the installation part. The first sensor protection pipe 10 is a long strip-shaped tubular structure, has a hollow cavity to form a first sliding channel 200, and the two ends of the first sliding channel 200 are open structures. The sensor wire harness of the electromagnetic navigation sensor can pass into 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. In the utility model, the sensor wire harness can only include the wire harness connected with the electromagnetic navigation sensor, or can include the wire harness connected with the electromagnetic navigation sensor and a protective sleeve or a protective pipe sleeved outside the wire harness.

[0057] Since the position of the sensor wire harness corresponding to the bending part of the ultrasonic probe will also bend when the ultrasonic wave emitting part bends, in order to better protect the sensor wire harness, as shown in the figure, Figure 1b In the embodiment, the front end of the first sensor protection pipe 2 extends out of the front end of the protection long pipe 1 and forms an extension section 201. At least a part of the extension section 201 is arranged as a transition section 202. The transition section 202 is formed by cutting the extension section 201 along a spiral line, and the transition section 202 corresponds to the bending part of the ultrasonic probe, and the sensor wire harness is arranged in the transition section 202.

[0058] Specifically, in the embodiment, the front end of the sensor wire harness extends the front end of the first sensor protection pipe 2 and is connected with the electromagnetic navigation sensor. A spiral transition section 202 is arranged on the extension section 201 of the first sensor protection pipe 2 extending out of the protection long pipe 1. The position of the transition section 202 is the bending position of the sensor wire harness. In the embodiment, the transition section 202 can be formed by cutting the hollow extension section 201. The transition section 202 can be bent at any angle without being broken, so as to protect the sensor wire harness and avoid the breakage of the extension section 201 of the first sensor protection pipe 2.

[0059] The utility model discloses one aspect in the electromagnetic navigation sensor is attached to ultrasonic probe 4, and sensor wire harness is arranged along first sliding channel 200, and sensor wire harness can slide in first sliding channel 200, on the other hand, the extension section 201 of first sensor protection tube 2 front end forms the transition section 202 of spiral with the position corresponding to the bending of ultrasonic probe 4, in the process of bending of ultrasonic probe 4 front end, transition section 202 is bent along, through the transition section 202 of spiral, can play the protection effect to sensor wire harness, and can have better bending and resilience, will not break under the larger bending angle, thereby solve the problem that the navigation sensor is installed to ultrasonic probe 4 in the related art, and sensor wire harness is easy to cause the protection tube of jacketing in the process of bending to break.

[0060] As Figure 6 For further protecting first sensor protection tube 2, the mounting tool in the embodiment further includes film covering support 9, and the film covering support 9 is fixedly sleeved at the front end of the protection long tube 1, and the first sensor protection tube 2 is arranged in the film covering support 9. When the ultrasonic wave emitting part is bent back, the film covering support 9 can prevent the first sensor protection tube 2 from being separated from the bending back part, causing the first sensor protection tube 2 to break and other damages. In the embodiment, the film covering support 9 can use the support in the related art, and the specific structure is not limited in the embodiment.

[0061] In the embodiment, the length of the film covering support 9 should meet that the front end of the film covering support 9 is located at the rear end of the bending part of the ultrasonic wave emitting part, and the film covering support 9 will not be bent and deformed with the ultrasonic wave emitting part. The transition section on the first sensor protection tube 2 can be selected to extend out of the front end of the film covering support 9 or not to extend out of the front end of the film covering support 9, and when extending out, the length of the extension should be controlled to be less than 3 mm.

[0062] For the installation of the film covering support 9 on the protection long tube 1, as Figure 6 And Figure 7 The film covering support 9 in the embodiment includes a large-diameter section 90 and a small-diameter section 91, and the large-diameter section 90 is fixedly sleeved at the front end of the protection long tube 1.

[0063] In one embodiment, the sensor wire harness is directly arranged in the first sliding channel 200. Since the sensor wire harness will slide relative to the sliding channel, in order to better protect the wire harness, in another embodiment, as Figure 7 The mounting tool further includes a second sensor protection tube 10, and the second sensor protection tube 10 is slidably arranged in the first sliding channel 200, and the second sensor protection tube 10 is provided with a third mounting channel, and the third mounting channel is used for mounting the electromagnetic navigation sensor.

[0064] In the embodiment, the electromagnetic navigation sensor is pre-installed in the third installation channel of the second sensor protection tube 10, and the front end of the electromagnetic navigation sensor extends out of the second sensor protection tube 10. The stripped sensor wire harness is accommodated in the third installation channel, and the sensor wire harness can be fixed with the second sensor protection tube 10 by point gluing. Then, the electromagnetic navigation sensor and the second sensor protection tube 10 are inserted into the first sliding channel 200 of the first sensor protection tube 2. During the movement of the electromagnetic navigation sensor with the ultrasonic emitter, the second sensor protection tube 10 will slide linearly in the first installation channel 100, and the second sensor protection tube 10 plays a protective role on the sensor wire harness.

[0065] In the embodiment, the second sensor protection tube 10 slides out of the transition section of the first sensor protection tube. The helically cut transition section can protect the first sensor protection tube and ensure sufficient bending performance.

[0066] In an embodiment of the mounting member 11, the mounting member 11 includes a protection long tube 1. Specifically, the protection long tube 1 is provided with a first installation channel 100 for installing an ultrasonic probe 4, and the protection long tube 1 is fixedly provided with a first sensor protection tube 2, and the first sensor protection tube 2 is provided with a first sliding channel 200 for the electromagnetic navigation sensor to pass through and accommodate the sensor wire harness.

[0067] The handle fixing assembly 3 is provided with a second installation channel 38, and the handle fixing assembly 3 is fixedly arranged at the end of the protection long tube 1. The second installation channel 38 is in communication with the first installation channel 100, and the second installation channel 38 is used for the front end of the ultrasonic probe 4 to pass through and accommodate the probe handle end 40 of the ultrasonic probe 4.

[0068] Since the electromagnetic navigation sensor needs to be connected with the wire harness for use, the arrangement of the sensor wire harness also needs to be considered. As shown in Figure 1a In the embodiment, the installation tool mainly includes a protection long tube 1, a first sensor protection tube 2, and a handle fixing assembly 3. The protection long tube 1 is a long strip-shaped tubular structure, has a hollow cavity to form a first installation channel 100, and the first installation channel 100 is used for the insertion of the ultrasonic probe 4. The handle fixing assembly 3 is fixed at the rear end of the protection long tube 1, and the handle fixing assembly 3 is provided with a second installation channel 38 in communication with the first installation channel 100. During installation, as shown in Figure 2As shown, the insertion tube of the ultrasound probe 4 is inserted through the second mounting channel 38 and, after passing through the first mounting channel 100, the ultrasonic emitting portion at the front end of the insertion tube passes through the front end of the first mounting channel 100. At this point, the probe handle 40 of the ultrasound probe 4 is located within the second mounting channel 38 of the handle fixing assembly 3, and the handle fixing assembly 3 secures the probe handle 40 of the ultrasound probe 4. One method of securing the probe handle 40 of the ultrasound probe 4 may be through a snap fastener or screw fastener, which is not limited in this embodiment.

[0069] 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;

[0070] 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.

[0071] 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.

[0072] 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.

[0073] Specifically, in this embodiment, the electromagnetic navigation sensor is inserted from the rear end of the first sliding channel 200, and the sensor harness is installed in the first sliding channel 200. When the electromagnetic navigation sensor is installed to the set position (i.e., the length extending from the first sliding channel 200 meets the design value), the sensor harness is installed in the slide 34 and fixed to the slider 35. The end of the sensor harness extends backward to connect with the device. As the electromagnetic navigation sensor moves with the ultrasonic transmitter, the sensor harness drives the slider 35 to slide in the slide 34. The slider 35 cooperates with the slide 34 to constrain the sensor harness while providing support for the movement of the electromagnetic navigation sensor. In addition, in this embodiment, after the sensor harness is set in the handle fixing assembly 3 of the tooling, the sensor harness as a whole is hidden in the tooling. The tooling can protect the sensor harness to avoid damage during use.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] On the basis of providing the chute 34, as Figure 8 As 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 .

[0078] Specifically, in the present embodiment, the buckling cover 37 is buckled and fixed on the handle fixing assembly 3, and the buckling cover 37 can cover on the sliding groove 34, thereby playing a protection role. The buckling cover 37 can be provided as a flip cover structure, one side of which is hinged with the handle fixing assembly 3, and the other side is buckled or screw-fixed with the handle fixing assembly 3. Of course, the buckling cover 37 can also be provided as a separate cover structure, and a buckle is arranged at the edge position of the buckling cover 37, which is buckled with the handle fixing assembly 3.

[0079] The handle fixing assembly 3 is a structure for fixing the probe handle end 40 of the ultrasonic probe 4, as shown in Figure 1a and Figure 2 In an embodiment, the handle fixing assembly 3 is fixed by embracing the probe handle end 40 of the ultrasonic probe 4. In the present embodiment, the handle fixing assembly 3 comprises a connecting piece 31, a first clamping fixing piece 32 and a second clamping fixing piece 33.

[0080] The connecting piece 31 is fixedly sleeved on the end of the protection long tube 1, and the first clamping fixing piece 32 and the second clamping fixing piece 33 are oppositely distributed, and the first clamping fixing piece 32 and the second clamping fixing piece 33 are used for clamping and fixing on the probe handle end 40 of the ultrasonic probe 4.

[0081] The sliding groove 34 is arranged on the first clamping fixing piece 32 or the second clamping fixing piece 33.

[0082] Specifically, it is necessary to explain that the handle fixing assembly 3 comprises the oppositely distributed first clamping fixing piece 32 and second clamping fixing piece 33, and the connecting piece 31 which can be fixed on the rear end of the protection long tube 1. The connecting piece 31 can be a ring structure which is sleeved and fixed on the rear end of the protection long tube 1, or at least two connecting blocks which are fixed on the rear end of the protection long tube 1. The second installation channel 38 is formed between the first clamping fixing piece 32 and the second clamping fixing piece 33, and the first clamping fixing piece 32 and the second clamping fixing piece 33 are first separated by a distance to leave an installation space when the ultrasonic probe 4 is installed. After the ultrasonic probe 4 is installed in place, the first clamping fixing piece 32 and the second clamping fixing piece 33 are adjusted to embrace the probe handle end 40 of the ultrasonic probe 4.

[0083] In an embodiment of the first clamping fixing piece 32 and the second clamping fixing piece 33, the first clamping fixing piece 32 and the second clamping fixing piece 33 can be hinged with the connecting piece 31, thereby being able to be opened or embraced in a rotating manner. In another embodiment, the first clamping fixing piece 32 and the second clamping fixing piece 33 can be slidingly connected with the connecting piece 31, and the sliding direction is radial, thereby being able to be opened or embraced in a straight line sliding manner.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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).

[0088] 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.

[0089] 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.

[0090] 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°.

[0091] In one embodiment of limiting the rotation angle, a limit lever can be provided on the fixed segment 320. The limit lever is 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. This is not described in detail in this embodiment.

[0092] As Figure 8 and Figure 9 shown, to achieve the locking of the first clamping fixture 32 and the second clamping fixture 33, the locking member 6 in the embodiment includes a first buckle 60 and a second buckle 61, the first buckle 60 is fixedly arranged at the second end of the movable section 321, the second buckle 61 is fixedly arranged at the second end of the second clamping fixture 33, and the first buckle 60 and the second buckle 61 are buckled connected.

[0093] Specifically, in the embodiment, after the first clamping fixture 32 and the second clamping fixture 33 are rotated and clamped on the probe handle end 40 of the ultrasonic probe 4, the first buckle 60 and the second buckle 61 can be operated to buckle and connect to achieve the locking of the first clamping fixture 32 and the second clamping fixture 33. In an embodiment of the first buckle 60 and the second buckle 61, at least one of the first buckle 60 and the second buckle 61 is provided with elasticity, and can be automatically clamped during the pressing process through the elasticity thereof.

[0094] Specifically, the first buckle 60 is provided with buckle grooves on both sides, the second buckle 61 includes a base 611, a torsion spring, and a clamping strip 610, the clamping strip 610 is provided with 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, the second end of the clamping strip 610 is provided with a push handle 612, and the buckle grooves and the clamping protrusion are buckled connected.

[0095] In the embodiment, during the buckling 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 clamping strip 610, and with the further buckling of the first clamping fixture 32 and the second clamping fixture 33, the first buckle 60 pushes the clamping strip 610 to rotate outwardly and compresses the torsion spring. When the buckle grooves on the first buckle 60 correspond to the clamping protrusion on the clamping strip 610, the first clamping fixture 32 and the second clamping fixture 33 are clamped on the probe handle end 40 of the ultrasonic probe 4, and at the same time, the clamping strip 610 rotates inwardly under the elastic force of the torsion spring, so that the buckle grooves and the clamping protrusion are engaged, thereby completing the locking.

[0096] When disassembly is needed, the clamping protrusion can be rotated to be separated from the buckle groove. In order to facilitate the rotation of the clamping strip 610 by the first buckle 60 during the locking, in the embodiment, the surface of the lower end of the first buckle 60 for contacting the clamping strip 610 is provided with an inclined surface, and the surface of the upper end of the clamping strip 610 for contacting the first buckle 60 is provided with an inclined surface, and the force is transmitted through the cooperation of the two inclined surfaces.

[0097] As Figure 9As shown, in order to facilitate the rotation of the clamping strip 610 when disassembled, a push handle 612 is arranged at the lower end of the clamping strip 610 in this embodiment, and the push handle 612 is perpendicular to the end face of the clamping strip 610. In an embodiment, in order to facilitate the installation of the clamping strip 610 and the torsion spring, the base 611 is arranged as a U-shaped seat, and an arc-shaped groove is arranged in the base 611. The two clamping strips 610 are arranged in an arc shape and are installed in the arc-shaped groove through a rotating shaft. The torsion spring is sleeved on the rotating shaft and located in the arc-shaped groove. The clamping strip 610 rotates in a certain angle range in the arc-shaped groove.

[0098] The sensor wire harness needs to pass out from the through hole at the rear end of the first clamping fixture 32 after being fixedly connected with the sliding block 35. In the bending process of the ultrasonic wave emitting part of the ultrasonic probe 4, the electromagnetic navigation sensor moves synchronously, so that the sensor wire harness drives the sliding block 35 to slide in the sliding groove 34 and pulls the rear end of the sensor wire harness to move. In the use process, the wire harness at the rear end of the first clamping fixture 32 is difficult to avoid being bent, and is thus easily damaged in the pulling process. Therefore, in order to avoid damage, a certain amount of slack is provided for the sensor wire harness in the sliding groove 34. Only the sensor wire harness in the sliding groove 34 moves in the movement process of the electromagnetic navigation sensor, and the sensor wire harness at the rear end of the first clamping fixture 32 remains stationary.

[0099] To achieve this purpose, as shown in the drawings, Figure 3 to Figure 5 The first clamping fixture 32 in this embodiment is further provided with a wire winding spring 7. The wire winding spring 7 is located at the rear end of the sliding block 35. The front end of the wire winding spring 7 is fixedly connected with the sliding block 35, and the rear end of the wire winding spring 7 is fixed on the handle fixing assembly 3. The wire winding spring 7 is used for winding the sensor wire harness.

[0100] The handle fixing assembly 3 is provided with a fixing part. The fixing part is located at the rear end of the wire winding spring 7, and is used for fixing the sensor wire harness.

[0101] The maximum stretching amount of the wire winding spring 7 is greater than the maximum sliding stroke of the sliding block 35 in the sliding groove 34.

[0102] Specifically, the wire winding spring 7 is a spring. After passing through the sliding block 35, the sensor wire harness can be wound on the wire winding spring 7 according to the spiral direction of the wire winding spring 7. After winding, the sensor wire harness passes out of the first clamping fixture 32 and is fixed on the first clamping fixture 32 by a pressing plate or the like. The front end of the wire winding spring 7 is fixedly connected with the sliding block 35, and the rear end is fixed on the first clamping fixture 32. The sliding block 35 moves linearly in the sliding groove 34, which stretches the wire winding spring 7.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] In an embodiment, the second sensor protection tube 10 needs to be installed on the slider 35, and the sensor wire harness also needs to be installed on the slider 35. Since the diameter of the sensor wire 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 in sequence 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 wire harness and part of the spring wire of the wire spring 7.

[0114] When the rear end of the sensor wire harness is wound on the wire spring 7 after passing through the second groove body 3501, the part of the sensor wire harness located in the second groove body 3501 and on the wire spring 7 is removed.

[0115] In an embodiment, the protection long 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 materials, or the protection long tube 1 is made of stainless steel materials.

[0116] According to another aspect of the present application, an ultrasonic probe assembly is provided, which includes the above-mentioned installation tool.

[0117] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
