[0064] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0065] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0066] like Figure 1 a and Figure 2 As shown, the embodiment of the present invention provides a protective tube tooling for an ultrasonic probe 4, comprising:

[0067] A protective long tube 1 is provided with a first installation channel 100 for passing an ultrasonic probe 4. A first sensor protection tube 2 is fixedly provided in the protective long tube 1. A first sliding channel 200 is established in the first sensor protection tube 2 for accommodating a sensor wiring harness.

[0068] The handle fixing assembly 3 is provided with a second mounting channel 38. The handle fixing assembly 3 is fixed to the end of the protective long tube 1. The second mounting channel 38 is communicated with the first mounting channel 100. The second mounting channel 38 is used for the front end of the ultrasonic probe 4 to pass through and accommodate the probe handle end 40 that fixes the ultrasonic probe 4.

[0069] In this embodiment, the protective tube fixture is primarily used to mount the ultrasonic probe 4 and the electromagnetic navigation sensor together. The ultrasonic probe 4 comprises a probe handle 40, a long, rectangular insertion tube, and an ultrasonic transmitter located at the front end of the tube. The electromagnetic navigation sensor is mounted on the back of the ultrasonic transmitter. The connection between the electromagnetic navigation sensor and the ultrasonic transmitter can be achieved using a specific snap-fit ​​assembly or adhesive, which is not limited in this embodiment.

[0070] In one embodiment, the electromagnetic navigation sensor and the ultrasonic transmitter can be connected via a specific snap assembly, which includes a probe snap, a slot, and a clamping member. The probe snap can be sleeved onto the ultrasonic transmitter, and the probe snap has an opening that avoids the transmission window of the ultrasonic transmitter. The slot is mounted on the inner side of the probe snap, and the electromagnetic navigation sensor is mounted on the slot. Under the action of the probe snap, it fits on the outer side of the ultrasonic transmitter. The clamping member can be sleeved on the rear end of the probe snap to clamp the probe snap to the ultrasonic transmitter. It should be noted that the structural description of the snap assembly in this embodiment is not restrictive, and those skilled in the art may also adopt snap assemblies with other structures.

[0071] Since electromagnetic navigation sensors need to be connected to wiring harnesses for use, the layout of the sensor wiring harnesses also needs to be considered. Figure 1 a As shown, in this embodiment, the protection tube tooling mainly includes a long protection tube 1, a first sensor protection tube 2, and a handle fixing assembly 3. The long protection tube 1 is a long tubular structure with a hollow cavity to form a first installation channel 100. The first installation channel 100 is used to insert the ultrasound probe 4. The handle fixing assembly 3 is fixed to the rear end of the long protection tube 1. The handle fixing assembly 3 is provided with a second installation channel 38 that is connected to the first installation channel 100. During installation, as shown in FIG. Figure 2 As 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.

[0072] After the ultrasonic probe 4 is installed on the protective tube fixture, the electromagnetic navigation sensor needs to be installed on the protective tube fixture. Figure 1 aAs shown, in this embodiment, a first sensor protection tube 2 is disposed within a long protective tube 1. The first sensor protection tube 2 is an elongated tubular structure with a hollow cavity forming a first sliding channel 200. Both ends of the first sliding channel 200 are open. The sensor harness of the electromagnetic navigation sensor can pass through the rear end of the first sliding channel 200 and extend to the front of the first sliding channel 200. The sensor harness is at least partially located within the first sliding channel 200.

[0073] 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;

[0074] 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.

[0075] 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.

[0076] For this reason, Figure 1 a 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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 .

[0082] 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.

[0083] The handle fixing assembly 3 is used as a structure for fixing the probe handle end 40 of the ultrasound probe 4. Figure 1 a 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;

[0084] 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;

[0085] The sliding groove 34 is provided on the first clamping fixture 32 or the second clamping fixture 33 .

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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 1 a 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.

[0090] 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.

[0091] 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 1 a 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).

[0092] 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.

[0093] 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.

[0094] 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°.

[0095] In an embodiment of limiting the rotation angle, a limiting stopper is arranged on the fixed section 320, which is located in the rotation direction of the movable section 321. When the movable section 321 rotates upward to contact the limiting stopper, the movable section 321 cannot rotate further, thereby limiting the maximum rotation angle of the movable section 321. In another embodiment, the rotation angle can be limited by adjusting the hinged part of the movable section 321 and the fixed section 320, which is not described herein.

[0096] As shown in FIGS. 1 and 2, the first clamping and fixing member 32 and the second clamping and fixing member 33 are arranged on the probe handle end 40 of the ultrasonic probe 4. Figure 8 And Figure 9 To achieve the locking of the first clamping and fixing member 32 and the second clamping and fixing member 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, and the second buckle 61 is fixedly arranged at the second end of the second clamping and fixing member 33. The first buckle 60 and the second buckle 61 are buckled and connected.

[0097] Specifically, in the embodiment, after the first clamping and fixing member 32 and the second clamping and fixing member 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 are operated to be buckled and connected, thereby achieving the locking of the first clamping and fixing member 32 and the second clamping and fixing member 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, which can be automatically clamped during the pressing process by the elasticity thereof.

[0098] Specifically, both sides of the first buckle 60 are provided with buckle grooves, and the second buckle 61 includes a base 611, a torsional spring, and a clamping strip 610. The clamping strip 610 is provided with two and is hinged at both sides of the base 611 through a rotating shaft. The torsional 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 grooves and the clamping protrusion are buckled and connected.

[0099] In the embodiment, during the buckling of the first clamping and fixing member 32 and the second clamping and fixing member 33, the lower end of the first buckle 60 abuts against the upper end of the clamping strip 610. With the further buckling of the first clamping and fixing member 32 and the second clamping and fixing member 33, the first buckle 60 pushes the clamping strip 610 to rotate outward and compresses the torsional spring. When the buckle grooves on the first buckle 60 correspond to the clamping protrusion on the clamping strip 610, the first clamping and fixing member 32 and the second clamping and fixing member 33 are clamped on the probe handle end 40 of the ultrasonic probe 4. At the same time, the clamping strip 610 rotates inward under the elastic force of the torsional spring, so that the buckle grooves and the clamping protrusion are engaged, thereby completing the locking.

[0100] When disassembly is needed, the clamping strip 610 can be rotated to make the clamping protrusion disengage from the buckle slot. In order to facilitate the rotation of the first buckle 60 to push the clamping strip 610 during locking, in the embodiment, the surface of the lower end of the first buckle 60 for contacting the clamping strip 610 is provided as an inclined surface, and the surface of the upper end of the clamping strip 610 for contacting the first buckle 60 is provided as an inclined surface, and the force transmission is realized through the cooperation of the two inclined surfaces.

[0101] As shown in Figure 9 In order to facilitate the rotation of the clamping strip 610 during disassembly, in the embodiment, a push handle 612 is provided at the lower end of the clamping strip 610, and the push handle 612 is perpendicular to the end surface of the clamping strip 610. In an implementation, in order to facilitate the installation of the clamping strip 610 and the torsional spring, the base 611 is provided as a U-shaped seat, an arc-shaped groove is provided in the base 611, the two clamping strips 610 are provided as arc shapes and are installed in the arc-shaped groove through a rotating shaft, and the torsional spring is sleeved on the rotating shaft and located in the arc-shaped groove, and the clamping strip 610 rotates in the arc-shaped groove within a certain angle range.

[0102] After the sensor wire harness is fixedly connected with the sliding block 35, it still needs to pass out from the through hole at the rear end of the first clamping fixing part 32. 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 fixing part 32 is difficult to avoid bending, so it is easy to be damaged in the pulling process. Therefore, in order to avoid damage, the sensor wire harness can have a certain excess amount in the sliding groove 34, and only the sensor wire harness in the sliding groove 34 moves with the electromagnetic navigation sensor in the movement process, and the sensor wire harness at the rear end of the first clamping fixing part 32 remains stationary.

[0103] To achieve this purpose, as shown in Figure 3 to Figure 5 The first clamping fixing part 32 in the 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, the rear end of the wire winding spring 7 is fixed on the handle fixing assembly 3, and the wire winding spring 7 is used for winding the sensor wire harness;

[0104] 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 the fixing part is used for fixing the sensor wire harness;

[0105] 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.

[0106] Specifically, the wire spring 7 is a spring, and the sensor wire bundle can be wound on the wire spring 7 according to the spiral direction of the wire spring 7 after passing through the sliding block 35. After winding, the sensor wire bundle passes out of the first clamping fixing member 32 and is tightly fixed on the first clamping fixing member 32 by a pressing plate or the like. The front end of the wire spring 7 is fixedly connected with the sliding block 35, and the rear end is fixed on the first clamping fixing member 32. The sliding block 35 moves linearly in the sliding groove 34, and in the process, the wire spring 7 is stretched.

[0107] First, when the front end of the ultrasonic wave emitting part is bent, the sliding block 35 slides in the sliding groove 34, and at the same time, the sliding block 35 pulls the wire spring 7 to deform and obtain elastic potential energy. When the ultrasonic wave emitting part recovers, the wire spring 7 can pull the sliding block 35 to reset. Secondly, since the sensor wire bundle is wound on the wire spring 7, when the wire spring 7 is stretched, the sensor wire bundle wound on the wire spring 7 deforms. Since the maximum stretching amount of the wire spring 7 is greater than the maximum sliding stroke of the sliding block 35 in the sliding groove 34, the maximum deformable amount of the sensor wire bundle is also greater than the maximum sliding stroke of the sliding block 35. Therefore, the sliding block 35 will not pull the rear end of the sensor wire bundle during the sliding process.

[0108] As shown in Figure 5 , in order to reasonably utilize the space, the wire spring 7 in the embodiment is arranged in the sliding groove 34. The fixed part is a fixed clamping groove arranged at the rear end of the sliding groove 34. A fixed plate is detachably fixed on the fixed clamping groove. The fixed plate is used to tightly press the sensor wire bundle in the fixed clamping groove.

[0109] Specifically, in the embodiment, the rear end of the sensor wire bundle is extended out of the first clamping fixing member 32 after being spirally wound on the wire spring 7. The part of the sensor wire bundle on the fixed clamping groove is tightly fixed by the fixed plate. During the movement of the electromagnetic navigation sensor, the part of the sensor wire bundle extended out of the first clamping fixing member 32 remains stationary, and only the part wound on the wire spring 7 is stretched with the stretching of the wire spring 7, so as to realize the follow-up movement with the electromagnetic navigation sensor, and completely avoid pulling the external sensor wire bundle.

[0110] Since the second end of the wire spring 7 needs to be fixed, in one embodiment, as shown in Figure 4 , a fixed seat 8 is arranged on the handle fixing assembly 3, especially on the first clamping fixing member 32. The fixed seat 8 is located in front of the fixed clamping groove, and the rear end of the wire spring 7 is fixedly connected with the fixed seat 8. A wire passing groove 80 is arranged on the fixed seat 8, and the wire passing groove 80 is used for the sensor wire bundle to pass through.

[0111] Specifically, in the embodiment, the rear end of the sensor wire harness passes through the wire slot 80 and then the fixing slot after being wound on the winding spring 7. The fixed connection between the rear end of the winding spring 7 and the fixed seat 8 can be achieved by welding, bonding or by a locking structure such as a locking screw, which is not limited in the embodiment.

[0112] In an embodiment, in order to fix the rear end of the winding spring 7, the fixed seat 8 is provided with a spring passing hole, which is located below the wire slot 80, and the rear end of the winding spring 7 is arranged in the spring passing hole and is locked and fixed. Specifically, in the embodiment, a threaded hole is arranged on the fixed seat 8 in the radial direction of the spring passing hole, and a locking screw is threadedly connected in the threaded hole, which can press the rear end of the winding spring 7 in the spring passing hole. Of course, other ways can also be used to fix it, and the above description is not restrictive.

[0113] As shown in Figure 4 , in order to control the stretching and contraction movement of the winding spring 7 within a set range, a guide column 81 is arranged at the front end of the fixed seat 8 in the embodiment, and the spiral part of the winding spring 7 is sleeved on the guide column 81. The stretching and contraction movement of the winding spring 7 is along the guide column 81, and the guide column 81 can avoid the deviation of the winding spring 7 during movement.

[0114] On the basis of the above-mentioned embodiment, in order to reduce the inner diameter of the first sensor protection tube 2, the sensor wire harness can be stripped, specifically, the part of the sensor wire harness corresponding to the first sensor protection tube 2 can be stripped to reduce the diameter of the part of the sensor wire harness, and then the diameter requirement of the first sensor protection tube 2 is reduced. Similarly, the part of the sensor wire harness located on the second sliding channel 36, the sliding groove 34, the sliding block 35 and the winding spring 7 can also be stripped. The part of the sensor wire harness fixed with the rear end of the first clamping and fixing part 32 can retain the wire skin, thereby improving the structural strength.

[0115] In an embodiment, the sensor wire harness is directly arranged in the first sliding channel 200 and the second sliding channel 36. Since the sensor wire harness will slide relative to the sliding channel, in order to better protect the wire harness, in another embodiment, as shown in Figure 7 , the protection tube tool further includes a second sensor protection tube 10, which is slidably arranged in the first sliding channel 200, and the second sensor protection tube 10 is provided with a third installation channel for installing an electromagnetic navigation sensor.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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 1 bAs 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.

[0122] 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.

[0123] like Figure 6 As shown, to further protect the first sensor protection tube 2, the protection tube fixture in this embodiment also includes a film support 9. The film support 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 film support 9. When the ultrasonic emitting portion bends back, the film support 9 prevents the first sensor protection tube 2 from separating from the bend, which could cause damage such as breakage. In this embodiment, the film support 9 can adopt a conventional support, and its specific structure is not limited in this embodiment.

[0124] 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 ensures that the first sensor protection tube 2 fits the curved portion of the ultrasound probe as closely as possible, 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 extended, the extension should be less than 3 mm.

[0125] 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 .

[0126] 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.

[0127] In one embodiment, the long protective 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.

[0128] like Figure 10 and Figure 11 a As shown, the embodiment of the present invention provides an installation tool for an ultrasound probe 4, which can be used in conjunction with the protective tube tool in the above embodiment to complete the assembly of the ultrasound probe and the electromagnetic navigation sensor. The installation tool includes:

[0129] Base 11;

[0130] The mounting base 12 is fixed on the base 11. The mounting base 12 is provided with an assembly channel 18. The mounting base 12 is provided with an assembly entrance 15 connected to the assembly channel 18. The assembly channel 18 is configured to accommodate the probe buckle 16;

[0131] The propulsion mechanism 13 includes a movable end 130 and a pushing end 131. The movable end 130 is configured to be able to move linearly along the axial direction of the ultrasonic probe 4. The pushing end 131 is configured to be able to connect with the clamping member 17 and, under the action of the movable end 131, push the clamping member 17 sleeved on the ultrasonic probe 4 toward the mounting seat 12 and sleeve the clamping member 17 tightly on the probe buckle 16.

[0132] In this embodiment, the installation tool is mainly used to sleeve the clamping member 17 onto the probe buckle 16, so that the probe buckle 16 can be tightly clamped on the ultrasonic emitting part of the ultrasonic probe 4, and thus the navigation sensor installed on the probe buckle 16, such as the electromagnetic navigation sensor, can maintain a relatively fixed positional relationship with the ultrasonic emitting part. Before using the installation tool, the navigation sensor and the probe buckle 16 need to be pre-assembled. The pre-assembly process varies depending on the different structures of the probe buckle 16. In one embodiment, Figure 17 to Figure 19 As shown, a slot 23 is provided within the probe clip 16, and the navigation sensor is fixed to the slot 23. During installation, the clamping member 17 is sleeved onto the first protective tube 2, positioned between the probe clip 16 and the membrane support 9. The front end of the ultrasound probe 4 is then inserted into the probe clip 16 from the rear end thereof. Finally, the clamping member 17 is pushed so that it snaps onto the rear end of the probe clip 16, thereby firmly clamping the probe clip 16 to the ultrasound probe 4. The clamping member 17 and the rear end of the probe clip 16 can be connected by a snap connection. For example, a plurality of slots are provided at the rear end of the probe clip 16, and a plurality of snaps are provided on the inner side of the clamping member 17. After the clamping member 17 is sleeved onto the rear end of the probe clip 16, the snaps snap into the corresponding slots, thereby firmly clamping the rear end of the probe clip 16 to the ultrasound probe 4.

[0133] When used with the protective tube fixture in the above embodiment, the pre-assembly process includes: inserting the electromagnetic navigation sensor into the second sensor protective tube 10, with the electromagnetic navigation sensor extending a certain distance beyond the front end of the second sensor protection tube. The sensor wiring harness is located within and secured to the second sensor protection tube 10, with the rear end of the sensor wiring harness extending beyond the rear end of the second sensor protection tube 10. The electromagnetic navigation sensor and the second sensor protection tube 10 are then inserted together into the first sensor protection tube 2 of the protective tube fixture, with the front ends of the electromagnetic navigation sensor and the second sensor protection tube 10 extending a certain distance beyond the front end of the first sensor protection tube 2. The rear end of the second sensor protection tube 10 then extends into the sliding channel and groove 34 within the first clamping fixture 32. The rear end of the sensor wiring harness extends beyond the second sensor protection tube, passes through the slider 35, and is wound around the winding spring 7. It then passes through the fixing seat 8 and exits the rear end of the first clamping fixture 32. The clamping member 17 is then fitted onto the first sensor protection tube 2, located in front of the protective tube 1 and behind the electromagnetic navigation sensor. The electromagnetic navigation sensor is installed in the card slot 1313, and the card slot 1313 is fixedly installed on the inner side of the probe card slot 1313.

[0134] To realize the above assembly process, Figure 10 and Figure 11 a As shown, the installation tool in this embodiment mainly includes a base 11, a mounting base 12 and a propulsion mechanism 13. Among them, the base 11 serves as a basic mounting structure. The base 11 can be set as a long plate-like structure. Of course, it can also be other structural forms, which are not limited in this embodiment. The mounting base 12 can be installed on the first end of the base 11 as a structure for accommodating the probe clip 16. An assembly channel 18 extending in the horizontal direction is provided on the mounting base 12, and an assembly entrance 15 connected to the assembly channel 18 is provided at the rear end (right end) of the mounting base 12.

[0135] After the pre-assembly is completed, the probe buckle 16 equipped with the navigation sensor can be installed into the assembly channel 18, and then the clamping piece 17 can be sleeved on the ultrasonic probe 4. At the same time, the front end of the ultrasonic probe 4 is inserted into the probe buckle 16. At this time, the clamping piece 17 is located behind the probe buckle 16 (such as Figure 11 a Then operate the pushing mechanism 13, which is mainly used to push the clamping member 17 forward so that it can be clamped on the rear end of the probe buckle 16 (as shown). Figure 15 In this embodiment, the propulsion mechanism 13 mainly includes a moving end 130 and a pushing end 131, wherein the moving end 130 is mainly used to drive the pushing end 131 to move, and the pushing end 131 is mainly used to maintain connection with the clamping member 17, so that the clamping member 17 is pushed by the moving end 130.

[0136] Specifically, when assembling with the above-mentioned protective tube tooling, after completing the above-mentioned pre-assembly, the probe clip 16 can be installed into the assembly channel 18, and the protective long tube 1 is placed on the base 11. The base 11 is provided with a corresponding support structure to support the protective long tube 1. The handle fixing assembly 3 at the rear end of the protective long tube 1 is located behind the base 11. Then the handle fixing assembly 3 is adjusted to install the ultrasonic probe 4 from the second installation channel 38 of the handle fixing assembly 3. The front end of the ultrasonic probe 4 is inserted into the probe clip 16 through the protective long tube 1 and the clamping member 17. Finally, the clamping member 17 is pushed by the propulsion mechanism 13 to move on the ultrasonic probe 4 and be sleeved on the probe clip 16. The entire assembled device is as follows: Figure 19 shown.

[0137] In one embodiment, the movable end 130 can be set on the base 11 and driven by a corresponding driving mechanism to move linearly. Of course, the movable end 130 can also be not set on the base 11, and be assembled and used as an independent component during installation. The pushing end 131 is connected to the movable end 130. In one embodiment, the pushing end 131 can move linearly along the radial direction of the ultrasonic probe 4. During installation, the pushing end 131 can move linearly close to the ultrasonic probe 4 and be located at the rear end of the clamping member 17. At this time, the front end surface of the pushing end 131 is close to or in contact with the rear end surface of the clamping member 17, so that the pushing end 131 can push the clamping member 17 to move linearly under the action of the movable end 130. After the installation is completed, the pushing end 131 can move in the opposite direction to facilitate the removal of the ultrasonic probe 4. In another embodiment, the pushing end 131 can be clamped on the clamping member 17 to push the clamping member 17 to move. The specific structure of the pushing end 131 is not limited in this embodiment, and those skilled in the art can design it according to actual needs.

[0138] In summary, during assembly, the present invention can first install the navigation sensor on the probe buckle 16, and then install the probe buckle 16 into the assembly channel 18 of the mounting seat 12 from the assembly entrance 15, and the clamping piece 17 is sleeved on the ultrasonic probe 4, and then the front end of the ultrasonic probe 4 is inserted into the probe buckle 16 from the rear end of the probe buckle 16, and finally the propulsion mechanism 13 moves the movable end 130 toward the mounting seat 12, and at the same time, the pushing end 131 is connected to the clamping piece 17. During the movement of the movable end 130, the pushing end 131 pushes the clamping piece 17 toward the probe buckle 16 until the clamping piece 17 is sleeved and fixed on the probe buckle 16, and the probe buckle 16 is tightly clamped on the ultrasonic probe 4, thereby achieving the technical effect of being able to conveniently and firmly sleeve the clamping piece 17 on the probe buckle 16, so as to stably clamp the probe buckle 16 on the ultrasonic probe 4, thereby solving the problem in the related art of lacking a tooling that can firmly sleeve the clamping piece 17 on the probe buckle 16.

[0139] According to the structural characteristics of the ultrasonic emitting portion of the ultrasonic probe 4, an ultrasonic emitting window 41 is provided on the ultrasonic emitting portion, and a notch needs to be provided in the probe buckle 16 to avoid the ultrasonic emitting window 41. To avoid interference of the probe buckle 16 with the ultrasonic emission, an emission avoidance groove 160 that matches the ultrasonic emitting window 41 needs to be provided on the probe opening. Since, during the above-mentioned installation process, the probe buckle 16 is pre-installed into the assembly channel 18 before the ultrasonic emitting portion is inserted into the probe buckle 16, it is necessary to avoid relative deflection between the ultrasonic emitting window 41 on the ultrasonic emitting portion and the emission avoidance groove 160 on the probe buckle 16. That is, the relative positions of the emission avoidance groove 160 and the ultrasonic emitting window 41 need to be calibrated during the installation process.

[0140] To achieve this purpose, in one embodiment, Figure 10 As shown, the mounting base 12 includes a fixed vertical plate 120 and a calibration mechanism 121. The fixed vertical plate 120 is fixed on the base 11. The fixed vertical plate 120 is provided with an assembly entrance 15.

[0141] The calibration mechanism 121 is provided with an assembly channel 18, such as Figure 13a As shown, the calibration mechanism 121 includes a fixing member 1211, which is used to abut against the open end surface of the emission avoidance groove 160 on the probe buckle 16 to position the open end surface to a relative horizontal position with respect to the calibration mechanism 121;

[0142] The calibration mechanism 121 is rotatably connected to the fixed vertical plate 120 , and the calibration mechanism 121 can rotate around the axis of the ultrasonic probe 4 to calibrate the relative position of the probe buckle 16 and the ultrasonic wave emission window 41 of the ultrasonic probe 4 .

[0143] Specifically, the fixed vertical plate 120 is provided with two which can be respectively installed at the front and rear ends of the calibration mechanism 121, and the assembly channel 18 is provided in the calibration mechanism 121. When calibrating the relative positions of the emission avoidance groove 160 and the ultrasonic emission window 41, it is necessary to adjust the position of one of them as a basis and the position of the other. For example, the position of the ultrasonic emission window 41 is adjusted based on the probe buckle 16, that is, the probe buckle 16 is fixed, and the relative position of the ultrasonic emission window 41 and the emission avoidance groove 160 is adjusted by rotating the ultrasonic probe 4. The position of the probe buckle 16 can also be adjusted based on the ultrasonic emission window 41, that is, the ultrasonic probe 4 is stationary, and the relative position of the two is adjusted by rotating the probe buckle 16. Since the ultrasonic probe 4 has a certain length, it is inconvenient to rotate it. In the present utility model, it is preferred to calibrate the position by rotating the probe buckle 16.

[0144] Therefore, the calibration mechanism 121 in this embodiment includes a fixing member 1211, which is provided in two groups and is respectively located on both sides of the axis of the assembly channel 18. The fixing member 1211 can fix the probe buckle 16 in the assembly channel 18 and locate the position of the probe buckle 16. Specifically, when the probe buckle 16 is installed in the assembly channel 18, the position of the probe buckle 16 is adjusted by the fixing member 1211 so that the emission avoidance groove 160 on the probe buckle 16 is in a relative horizontal position with respect to the calibration mechanism 121. The fixing member 1211 abuts against the open end face of the emission avoidance groove 160, specifically against the upper end faces of the side walls on both sides of the emission avoidance groove 160. When the probe buckle 16 is installed in the assembly channel 18 at a certain deflection angle, the fixing member 1211 can push the probe buckle 16 to rotate so as to calibrate the position of the probe buckle 16.

[0145] After the position of the probe buckle 16 is calibrated, the probe buckle 16 is fixed in the assembly channel 18. After the ultrasonic probe 4 is inserted, the relative position of the probe buckle 16 and the ultrasonic emission window 41 needs to be calibrated. In this embodiment, the relative position of the probe buckle 16 and the ultrasonic emission window 41 is calibrated by rotating the probe buckle 16 by the rotating base 1210.

[0146] On the basis of the above embodiment, in order to realize automatic calibration, it is expected that when the ultrasonic probe 4 is inserted into the probe buckle 16, the calibration mechanism 121 can drive the probe buckle 16 to rotate based on the ultrasonic emission window 41 to calibrate the relative position of the two. Figure 13a and Figure 13c As shown, the calibration mechanism 121 in this embodiment further includes a rotating seat 1210 and an elastic pressing member. The end of the rotating seat 1210 is rotatably connected to the fixed vertical plate 120 through a bearing;

[0147] An assembly channel 18 is provided in the rotating seat 1210 , and a fixing member 1211 is provided on the rotating seat 1210 ;

[0148] The elastic pressing member is arranged on the rotating seat 1210, and the elastic pressing member includes a first elastic part 1213 and a first pressing part 1212. Under the action of the first elastic part 1213, the first pressing part 1212 at least partially extends into the assembly channel 18 and is located on the assembly path of the ultrasonic emitting window 41.

[0149] Specifically, in this embodiment, the rotating base 1210 can rotate horizontally around the axis of the assembly channel 18, and the fixing member 1211 is mounted on the rotating base 1210 to fix the position of the calibration probe buckle 16. In this embodiment, the first pressing portion 1212 has a certain width and is parallel to the emission avoidance groove 160 on the probe buckle 16. When the ultrasonic emission window 41 is inserted into the probe buckle 16 at a certain deflection angle, a portion of the first pressing portion 1212 abuts against the higher side of the ultrasonic emission window 41. Under the action of the first elastic portion 1213, the first pressing portion 1212 tends to completely adhere to the surface of the ultrasonic emission window 41. Since the ultrasonic probe 4 is held by the operator during the insertion process, it will not rotate. Therefore, the force applied by the first elastic part 1213 to the first pressing part 1212 will react to the rotating seat 1210, thereby driving the rotating seat 1210 and the probe buckle 16 to rotate, so that when the rotating seat 1210 rotates, the first pressing part 1212 is completely attached to the ultrasonic emission window 41. At this time, the relative position of the ultrasonic emission window 41 and the emission avoidance groove 160 meets the requirements.

[0150] In this embodiment, the emission avoidance slot 160 on the probe buckle 16 is not necessarily in a horizontal state after installation. Its specific state is determined by the deflection state of the ultrasonic emission window 41 when inserted. The first elastic portion 1213 can be a spring or a spring, etc., which is not limited in this embodiment.

[0151] like Figure 13b As shown, in one embodiment of the fixing member 1211, in order to enable the fixing member 1211 to apply a certain pressure to the probe buckle 16 during the installation of the probe buckle 16 to calibrate the position of the probe buckle 16, the fixing member 1211 in this embodiment includes a second elastic portion 12111 and a second pressing portion 12110 arranged in the rotating seat 1210. Under the action of the second elastic portion 12111, the second pressing portion 12110 at least partially extends into the assembly channel 18 and is located on the assembly path of the probe buckle 16.

[0152] Specifically, in this embodiment, when the probe clip 16 is installed into the assembly channel 18 at a certain deflection angle, the upper end of one side wall of the launch avoidance groove 160 is higher than the upper end of the other side wall. Therefore, the higher side, upon contact with the corresponding second pressing portion 12110, will compress the second elastic portion 12111 connected to the second pressing portion 12110 to a greater extent. Similarly, the lower side, upon contact with the corresponding second pressing portion 12110, will compress the second elastic portion 12111 connected to the second pressing portion 12110 to a relatively smaller extent. Therefore, the second elastic portion 12111 with a greater compression amplitude will apply greater pressure to the corresponding second pressing portion 12110, thereby pushing the probe clip 16 to rotate within the assembly channel 18 by a certain angle until the compression amplitudes of the second elastic portions 12111 on both sides are close to or consistent. At this point, the probe clip 16 is in the correct position within the assembly channel 18, i.e., the launch avoidance groove 160 is in a horizontal position.

[0153] In one embodiment of the second elastic portion 12111 and the second pressing portion 12110, the second elastic portion 12111 includes a second spring, the second pressing portion 12110 includes a pressure column, the second spring is arranged in the rotating seat 1210, the first end of the pressure column is against the second spring, and the second end of the pressure column can extend into the assembly channel 18 under the action of the second spring, and against the open end face of the emission avoidance groove 160 on the probe buckle 16.

[0154] Specifically, in this embodiment, when the probe clip 16 is installed into the assembly channel 18, the lower end of the pressure column contacts the upper end surface of the side wall of the launch avoidance groove 160 and compresses the corresponding second spring. During the installation of the probe clip 16, the lower end of the pressure column and the upper end surface of the side wall of the launch avoidance groove 160 experience sliding friction. To reduce friction, a ball bearing can be provided at the lower end of the pressure column.

[0155] like Figure 13a and Figure 13b As shown, in one embodiment of the first elastic portion 1213 and the first pressing portion 1212 , the first elastic portion 1213 includes a first spring 12130 , and the first spring 12130 is disposed on the rotating seat 1210 ;

[0156] The first pressing portion 1212 includes a pressing block 12120 , a first end of the pressing block 12120 abuts against the first spring 12130 , and a second end of the pressing block 12120 can extend into the assembly channel 18 under the action of the first spring 12130 and abut against the ultrasonic emission window 41 .

[0157] In this embodiment, as the ultrasonic probe 4 is inserted into the probe clip 16, the second end of the pressing block 12120 abuts against the surface of the ultrasonic emission window 41, compressing the first spring 12130. When the ultrasonic emission window 41 deflects, the force applied by the first spring 12130 to the pressing block 12120 reacts on the rotating base 1210, driving the probe clip 16 to rotate, thereby calibrating the relative position of the emission avoidance slot 160 on the probe clip 16 and the ultrasonic emission window 41.

[0158] On the basis of the above embodiment, the pressure block 12120 is hinged on the inner side of the rotating seat 1210 through the rotating shaft, the first spring 12130 is against the end of the pressure block 12120 away from the rotating shaft, and the first rolling element 1214 is provided on the end of the pressure block 12120 away from the rotating shaft. The first rolling element 1214 can extend into the assembly channel 18 under the action of the first spring 12130 and against the ultrasonic emission window 41.

[0159] Specifically, in this embodiment, the rear end of the pressure block 12120 is hinged to the inner side of the rotating base 1210 via a rotating shaft. A first spring 12130 is disposed within the rotating base 1210, with the lower end of the first spring 12130 abutting against the upper end surface of the front end of the pressure block 12120. A first rolling element 1214 is disposed on the lower end surface of the front end of the pressure block 12120. The first rolling element 1214 can be a ball or a bearing, and the first rolling element 1214 reduces friction.

[0160] Since the movement of the mobile terminal 130 needs to be controlled during the installation process, in order to facilitate the linear movement of the mobile terminal 130, as shown in FIG. Figure 10 As shown, a linear drive mechanism 19 is provided on the base 11 in this embodiment. The linear drive mechanism 19 is transmission-connected to the moving end 130 for driving the moving end 130 to move linearly.

[0161] In this embodiment, the linear drive mechanism 19 can be a screw transmission mechanism, a cylinder, a hydraulic cylinder, etc., and there is no limitation on them in this embodiment. When the linear drive mechanism 19 is set as a screw transmission mechanism, the screw slider 193 of the screw transmission mechanism is fixedly connected to the movable end 130, and the screw 190 of the screw transmission mechanism rotates to drive the screw slider to move linearly, thereby driving the movable end 130 to move linearly. The pushing end 131 serves as a structure for pushing the clamping member 17. In this embodiment, the pushing end 131 includes a clamping member that can move linearly along the radial direction of the ultrasonic probe 4. During installation, the clamping member is controlled to move toward the ultrasonic probe 4, and the clamping member is clamped on the clamping member 17 or pressed against the end face of the clamping member 17, so that the clamping member 17 is pushed to move under the action of the movable end 130 so as to be sleeved and fixed on the probe buckle 16.

[0162] In one embodiment of the linear drive mechanism 19, as Figure 11 aAs shown, the linear driving mechanism 19 includes a lead screw transmission mechanism and a guide shaft 21, both of which are arranged on the base 11.

[0163] The moving end 130 is fixedly connected with the lead screw block 193 of the lead screw transmission mechanism, and is sleeved on the guide shaft 21.

[0164] In this embodiment, the guide shaft 21 is installed on the base 11, and both ends of the guide shaft 21 are fixed in guide seats which are fixed on the base 11, and the axis of the guide shaft 21 is parallel to the axis of the ultrasonic probe 4. The guide shaft 21 can guide the linear movement of the moving end 130, and at the same time, the lead screw 190 of the lead screw transmission mechanism can drive the linear movement of the lead screw block 193.

[0165] In one embodiment of the lead screw transmission mechanism, as shown in Figure 11 a The lead screw transmission mechanism includes a lead screw 190, a lead screw block 193, a lead screw mounting seat 192, and a hand crank 191. The lead screw 190 is rotatably connected to the lead screw mounting seat 192, and the lead screw block 193 is threadedly connected to the lead screw 190.

[0166] Specifically, in this embodiment, the lead screw 190 is arranged in a direction parallel to the ultrasonic probe 4, the lead screw mounting seat 192 is fixed on the base 11 and connected to both ends of the lead screw 190 through bearings, so that the lead screw 190 can rotate on the lead screw mounting seat 192. In order to facilitate the rotation of the lead screw 190, the front end of the lead screw 190 in this embodiment extends out of the base 11 and is connected to the hand crank 191. During installation, the hand crank 191 can be operated to rotate the lead screw 190, thereby driving the linear movement of the lead screw block 193 and the moving end 130.

[0167] In order to facilitate the movement of the clamping member 17, the moving end 130 in this embodiment is provided in two groups and symmetrically distributed on both sides of the base 11, the guide shaft 21 is provided in two and respectively connected with the moving end 130 on both sides, the lead screw transmission mechanism is arranged between the two moving ends 130, and the two groups of moving ends 130 are fixedly connected with the lead screw block 193.

[0168] Specifically, in this embodiment, the lead screw 190 is arranged between the two groups of moving ends 130, the lead screw block 193 is threadedly connected to the lead screw 190, and the two sides of the lead screw block 193 are fixedly connected with the two groups of moving ends 130 through connecting plates. One group of pushing ends 131 is arranged on each of the two groups of moving ends 130. During installation, the two groups of pushing ends 131 are respectively located on both sides of the ultrasonic probe 4, and the two groups of pushing ends 131 can be operated to move synchronously towards the ultrasonic probe 4 to be connected with both sides of the clamping member 17. In this embodiment, the two groups of moving ends 130 and the two groups of pushing ends 131 are arranged to balance the force on both sides of the clamping member 17 during installation, thereby avoiding the generation of a bias blockage.

[0169] like Figure 11 a to Figure 15 As shown, in one embodiment of the movable end 130, the movable end 130 includes a movable seat 1300, the pushing end 131 further includes a third spring 1312, and the clamping member includes a push rod 1311 and a clamping ring 1310. The push rod 1311 is slidably disposed in the movable seat 1300 and can be driven to move linearly. The third spring 1312 is sleeved on the push rod 1311.

[0170] The front end of the push rod 1311 extends out of the movable end 130 and is fixedly connected to the clamping ring 1310 . After clamping, the clamping ring 1310 abuts against the rear end surface of the clamping member 17 , and the rear end of the push rod 1311 extends out of the movable seat 1300 .

[0171] Specifically, during installation, the rear end of the push rod 1311 can be pulled outward, causing the clamping ring 1310 at the front end of the push rod 1311 to move backward, freeing space for installing the ultrasonic probe 4. During this process, the push rod 1311 compresses the third spring 1312. The ultrasonic probe 4 is then installed into the probe buckle 16, at which point the clamping member 17 is also engaged with the ultrasonic probe 4. The push rod 1311 is then released, and the clamping ring 1310 at the front end of the push rod 1311, under the action of the third spring 1312, moves toward the ultrasonic probe 4 until it aligns with the rear end surface of the clamping member 17. Finally, the movable base 1300 can be controlled to move. During this movement, the clamping ring 1310 pushes the rear end surface of the clamping member 17, causing the clamping member 17 to move linearly forward on the ultrasonic probe 4 until it engages the probe buckle 16. After the installation is completed, the push rod 1311 can be pulled outward again to separate the clamping ring 1310 from the intraoperative clamping member 17 and the ultrasonic probe 4, so as to facilitate the removal of the ultrasonic probe 4.

[0172] Because the inner diameter of the clamping member 17 is larger than the outer diameter of the ultrasonic probe 4 during installation, the upper end of the clamping member 17 abuts against the upper surface of the ultrasonic probe 4 after the ultrasonic probe 4 passes through the clamping member 17, resulting in an eccentric position between the clamping member 17 and the ultrasonic probe 4, while the ultrasonic probe 4 and the probe buckle 16 are concentric. Therefore, the connection between the clamping member 17 and the probe buckle 16 is easily blocked during the process of pushing the clamping member 17 to move. In addition, because the clamping member 17 is relatively thin, the clamping ring 1310 can easily slip off the clamping member 17 when the clamping member 17 is pushed only by contact with the rear end surface of the clamping member 17, resulting in assembly failure.

[0173] For this reason, Figure 11 b As shown, in this embodiment, a positioning protrusion 13100 is provided on one end of the clamping ring 1310 close to the clamping member 17. The positioning protrusion 13100 is used to be clamped into and fit onto the inner side of the clamping member 17 before pushing the clamping member 17 to locate the radial position of the clamping member 17.

[0174] Specifically, in this embodiment, after the front end of the ultrasonic probe 4 passes through the clamping member 17 and is inserted into the probe buckle 16, the clamping member 17, due to its own weight, causes the upper end to fit the upper surface of the ultrasonic probe 4, and the two are in an eccentric state. At this time, the movable end 130 drives the clamping ring 1310 to move toward the clamping member 17 so that the positioning protrusion 13100 is clamped into the clamping member 17. Under the action of the positioning protrusions 13100 on both sides, the clamping member 17 moves upward and is positioned to a position concentric with the ultrasonic probe 4. At this time, pushing the clamping member 17 forward again can determine the precise connection between the clamping member 17 and the probe buckle 16. In addition, because the positioning protrusion 13100 is clamped into the inner side of the clamping member 17, the clamping ring 1310 and the clamping member 17 are not easy to slip during the process of pushing the clamping member 17 to move, thereby improving the stability of the connection process. Figure 14 As shown, in one embodiment, a locking structure 22 is provided in the movable seat 1300 , and the locking structure 22 is used to lock the push rod 1311 in the first position, where the first position is the open position of the clamp ring 1310 ;

[0175] like Figure 11 a and Figure 14 As shown, a linkage structure 20 is provided on the base 11, and the linkage structure 20 is located in the moving direction of the movable seat 1300. The linkage structure 20 is configured to be able to link with the locking structure 22. When the movable seat 1300 moves to the second position, the linkage structure 20 triggers the locking structure 22 to release the clamping ring 1310. The second position is the position where the clamping ring 1310 is close to the rear end face of the clamping member 17.

[0176] Specifically, before installation, movable base 1300 is in its initial position. Push rod 1311 can be manually pulled outward. When push rod 1311 is pulled to the first position, locking mechanism 22 is triggered, locking push rod 1311 in the first position. In this embodiment, the first position of push rod 1311 corresponds to the open position of clamping ring 1310. That is, when clamping ring 1310 is in this position, the intraoperative probe can be installed. Once push rod 1311 is locked in the first position, the intraoperative ultrasound system can be installed in the probe clip 16, and movable base 1300 can then be controlled to move forward.

[0177] When the movable base 1300 moves forward to the second position, the linkage structure 20 on the base 11 triggers the locking structure 22 within the movable base 1300. At this time, the locking structure 22 releases the push rod 1311 under the action of the linkage structure 20. The push rod 1311 moves inward under the action of the third spring 1312, causing the clamping ring 1310 to move toward the ultrasonic probe 4. Because the clamping ring 1310 needs to abut against the rear end surface of the clamping member 17 to push the clamping member 17 to move, the second position in this embodiment refers to the position of the movable base 1300 when the projection of the clamping ring 1310 on the ultrasonic probe 4 is close to the rear end surface of the clamping member 17.

[0178] In this embodiment, the locking structure 22 and the linkage structure 20 can be configured in various forms, and can be triggered by a mechanical structure. Figure 14 and Figure 16 As shown, a locking groove 1313 can be provided on the push rod 1311. The locking structure 22 includes a locking rod 220 and a fourth spring 221 provided in the movable seat 1300. The locking rod 220 is hinged in the base 11. The fourth spring 221 is connected to the locking rod 220. The first end of the locking rod 220 is engaged with the locking groove 1313.

[0179] The second end of the card rod 220 extends out of the lower end of the movable seat 1300 and corresponds to the linkage structure 20. When the movable seat 1300 moves to the second position, the linkage structure 20 pushes the second end of the card rod 220 to rotate the card rod 220 so that the first end of the card rod 220 disengages from the slot 1313.

[0180] When the movable seat 1300 is in the initial position, the push rod 1311 can be pulled outward. When the push rod 1311 is pulled to the first position, the slot 1313 corresponds to the first end of the latch rod 220. Under the action of the fourth spring 221, the first end of the latch rod 220 is locked in the slot 1313 to lock the push rod 1311. At this time, the second end of the latch rod 220 extends out of the lower end of the movable seat 1300.

[0181] As the movable base 1300 moves to the second position, the second end of the latching rod 220 gradually approaches the linkage structure 20. After the second end of the latching rod 220 contacts the linkage structure 20, as the movable base 1300 moves further, the latching rod 220 rotates about the hinge point, causing the first end of the latching rod 220 to gradually disengage the latching slot 1313. When the movable base 1300 reaches the second position, the first end of the latching rod 220 completely disengages the latching slot 1313. At this time, the push rod 1311, under the action of the third spring 1312, pushes the clamping ring 1310 forward until it aligns with the rear end surface of the clamping member 17.

[0182] like Figure 14 As shown, in one embodiment, the latching rod 220 may include two vertical portions and a horizontal portion, with the two vertical portions fixed to the ends of the horizontal portion. The middle portion of the horizontal portion is hinged to the movable base 1300 via a rotating shaft. The vertical portion at the front end of the horizontal portion is configured to engage with the latching slot 1313. The vertical portion at the rear end of the horizontal portion can extend beyond the lower end of the movable base 1300 and engage with the linkage structure 20. The lower end of the fourth spring 221 is connected to the horizontal portion.

[0183] In order to enable the first end of the locking rod 220 to automatically fit into the locking slot 1313 when the push rod 1311 is pulled to the first position, in this embodiment, inclined surfaces can be set at the first end of the locking rod 220 and the position at the rear end of the locking slot 1313 on the push rod 1311, and automatic locking is achieved through the cooperation of the two inclined surfaces.

[0184] Based on the above implementation, Figure 11 a As shown, the linkage structure 20 includes a linkage block fixed on the base 11 , on which a linkage slope 201 and a linkage plane 202 are provided. The linkage slope 201 and the linkage plane 202 are arranged in sequence along the moving direction of the moving seat 1300 toward the mounting seat 12 .

[0185] Specifically, in this embodiment, the linkage blocks are arranged on both sides of the base 11 and correspond to the movable seat 1300. The upper surface of the linkage block includes a linkage inclined surface 201 and a linkage plane 202. When the push rod 1311 is locked by the locking rod 220, as the movable seat 1300 moves forward, the second end of the locking rod 220 gradually approaches the linkage inclined surface 201. When the second end of the locking rod 220 contacts the linkage inclined surface 201, as the movable seat 1300 moves further, the locking rod 220 will rotate about the hinge point, causing the first end of the locking rod 220 to gradually fall off the locking groove 1313 on the push rod 1311. When the second end of the clamping rod 220 moves to the linkage plane 202, the first end of the clamping rod 220 will completely disengage from the clamping slot 1313 to release the clamping ring 1310, and the clamping ring 1310 will move to correspond to the rear end surface of the clamping member 7. As the movable seat 1300 moves further, the second end of the clamping rod 220 will move on the linkage plane 202. During this process, the clamping ring 1310 pushes the clamping member 17 toward the probe buckle 16 and is sleeved on the probe buckle 16.

[0186] To reduce friction between the second end of the latching rod 220 and the linkage block, a second rolling element 222 is provided at the second end of the latching rod 220 in this embodiment. The second rolling element 222 is configured to cooperate with the linkage inclined surface 201 and the linkage flat surface 202. The second rolling element 222 can be a ball bearing or a bearing, etc., and is not limited to this embodiment.

[0187] It is understood that in addition to mechanical linkage, the locking structure 22 and the linkage structure 20 of the present invention can also be electrically linked. Specifically, the locking structure 22 can electrically lock and release the push rod 1311, for example, the locking structure 22 is an electromagnetic lock. During the movement of the movable base 1300, the position of the movable base 1300 can be detected by a corresponding displacement sensor. When the movable base 1300 moves to the second position, a corresponding electrical signal is triggered, and the locking structure 22 is controlled to release the push rod 1311.

[0188] In order to better push the clamping member 17, as Figure 14As shown, the clamp ring 1310 in this embodiment is configured as a semicircle, and the upper and lower ends of the clamp ring 1310 on both sides are provided with a first plug-in portion and a second plug-in portion that fit in with the plug-in.

[0189] Since the ultrasonic probe 4 has a long insertion tube, the ultrasonic probe 4 can be connected to the probe buckle 16 horizontally, as shown in FIG. Figure 10 As shown, in this embodiment, a plurality of support seats 14 are further provided on the base 11 . The support seats 14 are provided with support grooves for supporting the ultrasonic probe 4 . The support grooves correspond to the assembly entrance in front and back.

[0190] 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.
