[0064] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0065] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments 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 and Figure 2 As shown, an embodiment of the present invention provides a protective tube tooling for an intraoperative ultrasound probe 4, comprising:

[0067] A protective long tube 1 is provided with a first installation channel 100 in the protective long tube 1. The first installation channel 100 is used to install an intraoperative ultrasound probe 4. A first sensor protection tube 2 is fixed in the protective long tube 1. A first sliding channel 200 is established in the first sensor protection tube 2. The first sliding channel 200 is used for the electromagnetic navigation sensor to pass through and accommodate the sensor harness;

[0068] The handle fixing assembly 3 is provided with a second mounting channel 38, and the handle fixing assembly 3 is fixed at 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 intraoperative ultrasound probe 4 to pass through and accommodate and fix the probe handle end 40 of the intraoperative ultrasound probe 4.

[0069] In this embodiment, the protective tube tooling is mainly used to install the intraoperative ultrasound probe 4 and the electromagnetic navigation sensor together. The intraoperative ultrasound probe 4 includes a probe handle end 40, a long strip insertion tube, and an ultrasonic transmitter located at the front end of the insertion tube. The electromagnetic navigation sensor needs to be installed on the back of the ultrasonic transmitter. The electromagnetic navigation sensor and the ultrasonic transmitter can be connected by a specific snap assembly or adhesive, etc., which is not limited in this embodiment.

[0070] In one embodiment, the electromagnetic navigation sensor and the ultrasonic transmitter can be connected through a specific snap assembly, which includes a probe snap, a slot and a clamping member. The probe snap can be sleeved on the ultrasonic transmitter, and the probe snap has an opening to avoid the emission window of the ultrasonic transmitter. The slot is installed on the inner side of the probe snap, and the electromagnetic navigation sensor is installed 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 hold the probe snap tightly on 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 use 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 As shown, in this embodiment, the protection tube tooling 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 tubular structure with a hollow cavity to form a first installation channel 100, and the first installation channel 100 is used for inserting the ultrasound probe 4 during surgery. The handle fixing assembly 3 is fixed to the rear end of the protection long tube 1, and a second installation channel 38 connected to the first installation channel 100 is provided on the handle fixing assembly 3. During installation, as shown in FIG. Figure 2 As shown, the insertion tube of the intraoperative ultrasound probe 4 is inserted from the second installation channel 38 and after passing through the first installation channel 100, the ultrasonic emitting part located at the front end of the insertion tube passes through the front end of the first installation channel 100. At this time, the probe handle end 40 of the intraoperative ultrasound probe 4 is located in the second installation channel 38 of the handle fixing assembly 3, and the probe handle end 40 of the intraoperative ultrasound probe 4 is fixed by the handle fixing assembly 3. In one fixing method, it can be fixed by buckle fixing or screw fixing, etc., which is not limited in this embodiment.

[0072] After the ultrasound probe 4 is installed on the protection tube fixture during the operation, the electromagnetic navigation sensor needs to be installed on the protection tube fixture. Figure 1As shown, in this embodiment, a first sensor protection tube 2 is disposed in the protection long tube 1. The first sensor protection tube 2 is a long tubular structure with a hollow cavity to form a first sliding channel 200. Both ends of the first sliding channel 200 are open structures. The sensor harness of the electromagnetic navigation sensor can penetrate from 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 in the first sliding channel 200.

[0073] On one hand, the present invention establishes an installation channel for the intraoperative ultrasound 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 protective tube 2, so as to facilitate the installation and combination of the intraoperative ultrasound probe 4 and the electromagnetic navigation sensor, thereby solving the problem of inconvenient installation and combination of the navigation device and the intraoperative ultrasound probe 4 in the related art;

[0074] On the other hand, after installation, the protective long tube 1 can protect the intraoperative ultrasound probe 4, and the first sensor protection tube 2 can also protect the sensor harness, thereby avoiding damage during use and improving safety of use.

[0075] In one embodiment of the intraoperative ultrasound probe 4, the ultrasound transmitting part can be bent relative to the insertion tube, and the bending process is controlled by a wrench on the probe handle end 40. Since the electromagnetic navigation sensor is fixed to the ultrasound transmitting part, the electromagnetic navigation sensor also moves with the ultrasound transmitting part, so the sensor harness connected to the electromagnetic navigation sensor needs to be able to slide in the first sliding channel 200.

[0076] For this reason, Figure 1 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 from the rear end of the first sliding channel 200, and the sensor harness is inserted in the first sliding channel 200. When the electromagnetic navigation sensor is installed to the set position (i.e., the length extending out of the first sliding channel 200 meets the design value), the sensor harness is installed in the slide groove 34, and the sensor harness is fixed on the slider 35, and the end of the sensor harness extends backward to connect with the device. In the process of the electromagnetic navigation sensor moving with the ultrasonic transmitter, the sensor harness drives the slider 35 to slide in the slide groove 34, and the slider 35 cooperates with the slide groove 34 to provide support for the movement of the electromagnetic navigation sensor while constraining the sensor harness. In addition, in this embodiment, after the sensor harness is set in the handle fixing assembly 3 of the tooling, the sensor harness is hidden in the tooling as a whole, and the tooling can protect the sensor harness to avoid damage during use. In the present invention, the sensor harness may only include a harness connected to the electromagnetic navigation sensor, or may include a harness connected to the electromagnetic navigation sensor and a protective sleeve or protective tube sleeved outside the harness.

[0078] The handle fixing assembly 3 is used by doctors to hold and operate the intraoperative ultrasound probe 4, so it has a length and shape that meet the operation requirements. Since the movement of the electromagnetic navigation sensor is only to follow the bending and deformation of the ultrasonic emitting part relative to the intraoperative ultrasound probe within a certain angle, the sliding stroke of the moving 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, such as Figure 5 As shown, in this embodiment, a second sliding channel 36 is provided on the handle fixing assembly 3 , and two ends of the second sliding channel 36 are respectively connected to the first sliding channel 200 and the sliding groove 34 .

[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, and the slide groove 34 needs to provide a sliding track for the slider 35. Figure 5 As shown, in this embodiment, the slide 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 slide 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-on and fixed to the handle fixing assembly 3, and the snap-on cover 37 can cover the slide groove 34, thereby playing a protective role. The snap-on cover 37 can be set as a flip-top structure, one side of which is hinged to the handle fixing assembly 3, and the other side is snap-connected or screw-fixed to the handle fixing assembly 3. Of course, the snap-on cover 37 can also be set as a separate cover-like structure, with snaps set at the edge of the snap-on cover 37, and snap-connected to the handle fixing assembly 3 through the snaps.

[0083] The handle fixing assembly 3 is used as a structure for fixing the probe handle end 40 of the ultrasound probe 4 during surgery. Figure 1 and Figure 2 As shown, in one embodiment, the handle fixing assembly 3 is fixed by holding the probe handle end 40 of the intraoperative 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 fixing member 32 and the second clamping fixing member 33 are arranged relatively to each other. The first clamping fixing member 32 and the second clamping fixing member 33 are used to clamp and fix the probe handle end 40 of the ultrasonic probe 4 during surgery;

[0085] The sliding groove 34 is disposed 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 intraoperative ultrasound 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 intraoperative ultrasound probe 4 is installed in place, the first clamping fixture 32 and the second clamping fixture 33 are adjusted to hold the probe handle end 40 of the intraoperative ultrasound 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 may be hinged to the connecting member 31, so that they can be opened or clamped in a rotating manner. In another embodiment, the first clamping fixture 32 and the second clamping fixture 33 may be slidably connected to the connecting member 31, and the sliding direction is radial, so that they can be opened or clamped in a linear sliding manner.

[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 embodiment does not limit this. On this basis, in order to improve the degree of the two clamping fixtures to hold the probe handle end 40 of the intraoperative ultrasound probe 4 tightly, the inner side profiles of the first clamping fixture 32 and the second clamping fixture 33 in this embodiment have a surface profile that matches the probe handle end 40 of the intraoperative 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 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 holding. Figure 1 As shown, in this embodiment, the first clamping fixture 32 is divided into two sections, which can be specifically divided into 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 connecting member 31 (when the connecting member 31 is a ring structure, the upper side here refers to the upper area of ​​the end face of the connecting member 31), and the rear end is movably connected to the movable section 321. After the fixed section 320 and the connecting member 31 are fixedly connected, the two can be integrally formed or end-face welded, so that the connection position of the fixed section 320 and the connecting member 31 is relatively smooth, so that it is easy to operate when the fixed section 320 is used as the doctor's gripping section.

[0090] In addition, it should be noted that the length of the fixed section 320 should be selected based on the structure of the probe handle end 40 of the intraoperative ultrasound probe 4 in addition to the doctor's gripping area. In one embodiment, the probe handle end 40 of the intraoperative ultrasound probe 4 has a protrusion in the middle. Since the fixed section 320 is a fixed structure, considering the installation of the probe handle end 40, the rear end of the fixed section 320 cannot exceed the apex of the protrusion on the probe handle end 40. When the probe handle end 40 of the intraoperative ultrasound probe 4 has other structures, the fixed section 320 also needs to be adjusted according to the structural characteristics of the probe handle end 40, which will not be described 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 ultrasound probe 4 during surgery, a rotational motion is adopted in this embodiment. Figure 1 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 intraoperative ultrasound 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 intraoperative ultrasound 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, in order to facilitate the gripping of the probe handle end 40, in this embodiment, the second end of the movable section 321 and the second end of the second clamping fixture 33 are detachably fixedly connected by a locking member 6. The locking member 6 in this embodiment serves to connect the second end of the movable section 321 and the second clamping fixture 33. In one embodiment, the locking member 6 can be a latch, a locking screw or a buckle 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 groove 34 is arranged 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 part of the movable section 321 has a third sliding section 363, and the rear part of the movable section 321 has a slide groove 34, and the slide groove 34 is connected to the third sliding section 363. The end of the first sensor protection tube 2 extends to the third sliding section 363 through the first sliding section 361 and the second sliding section 362, and the end of the first sensor protection tube 2 can selectively extend into the slide groove 34 or not extend into the slide groove 34. Since the end of the first sensor protection tube 2 extends into the movable section 321 through the fixed section 320, when the intraoperative ultrasound probe 4 is installed, the movable section 321 needs to be rotated and opened relative to the fixed section 320. In order to avoid the first sensor protection tube 2 from being bent and damaged due to excessive rotation angle, the maximum rotation angle of the movable section 321 needs to be limited. In one embodiment, when the movable section 321 is at the 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 limit lever is provided on the fixed section 320, and the limit lever is located in the rotation direction of the movable section 321. When the movable section 321 rotates upward to contact with the limit lever, 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 portion of the movable section 321 and the fixed section 320, which will not be described in detail in this embodiment.

[0096] like Figure 8 and Fig. 9 As shown, in order to achieve locking of the first clamping fixture 32 and the second clamping fixture 33, the locking member 6 in this embodiment includes a first buckle 60 and a second buckle 61. The first buckle 60 is fixed to the second end of the movable section 321, and the second buckle 61 is fixed to the second end of the second clamping fixture 33. The first buckle 60 and the second buckle 61 are buckled in connection.

[0097] Specifically, in this embodiment, after the first clamping fixture 32 and the second clamping fixture 33 are rotated and tightly embraced on the probe handle end 40 of the intraoperative ultrasound probe 4, the first buckle 60 and the second buckle 61 can be operated to buckle and connect to achieve 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 configured to have elasticity, and can automatically snap in during the pressing process due to its own elasticity.

[0098] Specifically, buckle grooves are provided on both sides of the first buckle 60, and the second buckle 61 includes a base 611, a torsion spring and a clamping strip 610. The clamping strip 610 is provided in two and is hinged on both sides of the base 611 through a rotating shaft. The torsion spring is sleeved on the rotating shaft. A clamping protrusion is provided at the first end of the clamping strip 610, and a push handle 612 is provided at the second end of the clamping strip 610. The buckle groove and the clamping protrusion are buckled and connected.

[0099] In this embodiment, during the process of buckling 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. As the first clamping fixture 32 and the second clamping fixture 33 are further buckled, the first buckle 60 pushes the clamping strip 610 to rotate outward and compresses the torsion spring. When the buckle groove on the first buckle 60 corresponds to the clamping protrusion on the clamping strip 610, the first clamping fixture 32 and the second clamping fixture 33 are tightly held on the probe handle end 40 of the intraoperative ultrasound probe 4, and at the same time, the clamping strip 610 rotates inward under the elastic force of the torsion spring, so that the buckle groove and the clamping protrusion bite, thereby completing the locking.

[0100] When disassembly is required, the clamping strip 610 can be rotated to disengage the clamping protrusion from the clamping groove. In order to facilitate the first clamping strip 60 to push the clamping strip 610 to rotate during the locking process, in this embodiment, the surface at the lower end of the first clamping strip 60 for contacting the clamping strip 610 is set as an inclined surface, and the surface at the upper end of the clamping strip 610 for contacting the first clamping strip 60 is set as an inclined surface, and the force transmission is achieved through the cooperation of the two inclined surfaces.

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

[0102] After the sensor harness is fixedly connected to the slider 35, it also needs to pass through the through hole at the rear end of the first clamping fixture 32. During the bending of the ultrasonic emitting portion of the ultrasound probe 4 during the operation, the electromagnetic navigation sensor moves synchronously, so that the sensor harness drives the slider 35 to slide in the slide groove 34, and pulls the rear end of the sensor harness to move. Since the harness at the rear end of the first clamping fixture 32 is inevitably bent during use, it is easily damaged during the pulling process. Therefore, in order to avoid damage, the sensor harness can have a certain margin in the slide groove 34. During the movement of the electromagnetic navigation sensor, only the sensor harness in the slide groove 34 moves, and the harness at the rear end of the first clamping fixture 32 remains stationary.

[0103] To achieve this goal, Figures 3 to 5 As shown, in this embodiment, a winding spring 7 is also provided on the first clamping fixture 32. The winding spring 7 is located at the rear end of the slider 35. The front end of the winding spring 7 is fixedly connected to the slider 35. The rear end of the winding spring 7 is fixed to the handle fixing assembly 3. The winding spring 7 is used for winding the sensor harness.

[0104] The handle fixing assembly 3 is provided with a fixing portion, which is located at the rear end of the winding spring 7 and is used to fix the sensor harness;

[0105] The maximum stretching amount of the winding spring 7 is greater than the maximum sliding stroke of the slider 35 in the sliding groove 34 .

[0106] Specifically, the winding spring 7 is a spring, and the sensor harness can be wound on the winding spring 7 according to the spiral direction of the winding spring 7 after passing through the slider 35. After winding, the sensor harness passes through the first clamping fixture 32 and is pressed and fixed on the first clamping fixture 32 by a pressure plate and other structures. The front end of the winding spring 7 is fixedly connected to the slider 35, and the rear end is fixed on the first clamping fixture 32. The slider 35 stretches the winding spring 7 during the linear movement in the slide groove 34.

[0107] First, when the ultrasonic emitting part at the front end bends, the slider 35 slides in the slide groove 34 in a linked manner, and at the same time, the slider 35 pulls the winding spring 7 to deform and obtain elastic potential energy. When the ultrasonic emitting part recovers, the winding spring 7 can pull the slider 35 to reset. Secondly, since the sensor harness is wound on the winding spring 7, when the winding spring 7 is stretched, the sensor harness wound on the winding spring 7 is deformed. Since the maximum stretching amount of the winding spring 7 is greater than the maximum sliding stroke of the slider 35 in the slide groove 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.

[0108] like Figure 5 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.

[0109] Specifically, in this embodiment, the rear end of the sensor harness is spirally wound on the winding spring 7 and then extends out of the first clamping fixture 32 through the fixed card slot. The portion of the sensor harness on the fixed card slot is pressed and fixed by the fixing plate. During the movement of the electromagnetic navigation sensor, the portion of the sensor harness extending out of the first clamping fixture 32 remains stationary, and only the portion wound on the winding spring 7 stretches as the winding spring 7 stretches, thereby achieving follow-up with the electromagnetic navigation sensor and completely avoiding pulling on the external sensor harness.

[0110] 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 wire harness to pass through.

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

[0112] In one embodiment, in order to facilitate the fixing of the rear end of the winding spring 7, a spring hole is provided on the fixing seat 8, and the spring hole is located below the wire slot 80. The rear end of the winding spring 7 is inserted into the spring hole and locked and fixed. Specifically, in this embodiment, a threaded hole is provided on the fixing seat 8 along the radial direction of the spring hole, and a locking screw is threadedly connected in the threaded hole. The locking screw can press the rear end of the winding spring 7 into the spring hole. Of course, those skilled in the art can also adopt other methods for fixing, and the above description is not restrictive.

[0113] like Figure 4 As shown, in order to control the stretching and contraction movement of the winding spring 7 within a set range, a guide column 81 is provided at the front end of the fixing seat 8 in this embodiment, and the spiral portion of the winding spring 7 is sleeved on the guide column 81. The stretching and contraction movement of the winding spring 7 are both performed along the guide column 81, and the guide column 81 can prevent the winding spring 7 from being deviated during the movement.

[0114] On the basis of the above embodiment, in order to reduce the inner diameter of the first sensor protection tube 2, the sensor wire harness can be stripped. Specifically, the portion of the sensor wire harness corresponding to the first sensor protection tube 2 can be stripped, thereby reducing the diameter of the portion of the sensor wire harness, thereby reducing the diameter requirement of the first sensor protection tube 2. Similarly, the portion of the sensor wire harness located on the second sliding channel 36, the slide groove 34, the slider 35 and the winding spring 7 can also be stripped. The portion of the sensor wire harness fixed to the rear end of the first clamping fixture 32 can retain the wire skin, thereby improving the structural strength.

[0115] In one embodiment, the sensor harness is directly arranged in the first sliding channel 200 and the second sliding channel 36. Since the sensor harness will slide relative to the sliding channel, in order to better protect the harness, in another embodiment, as shown in FIG. Figure 7 As shown, the protection tube tooling also includes a second sensor protection tube 10, which is slidably arranged in the first sliding channel 200. A third installation channel is arranged in the second sensor protection tube 10, and the third installation channel is used to install the electromagnetic navigation sensor.

[0116] In this embodiment, during installation, the electromagnetic navigation sensor can be inserted into the third installation channel of the second sensor protection tube 10 in advance, and the front end of the electromagnetic navigation sensor can extend out of the second sensor protection tube 10. The sensor harness after peeling is accommodated in the third installation channel, and the sensor harness can be fixed with the second sensor protection tube 10 by glue. 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 together. When the electromagnetic navigation sensor moves with the ultrasonic transmitter, the second sensor protection tube 10 will slide linearly in the first installation channel 100, and the second sensor protection tube 10 plays a role in protecting the sensor harness.

[0117] like Figure 5 As shown, in one embodiment, the rear end of the first sensor protection tube 2 extends to the vicinity of the middle of the third sliding section 363, the rear end of the second sensor protection tube 10 extends out of the rear end of the first sensor protection tube 2 and extends into the slide groove 34 through the third sliding section 363, and is finally fixed on the slider 35. The rear of the stripped wire harness on the sensor harness extends out of the rear end of the second sensor protection tube 10 and passes through the slider 35 before being wound around the winding spring 7, and the part of the sensor harness with the wire skin passes through the first clamping fixture 32 and is fixed on the first clamping fixture 32.

[0118] To facilitate the installation of the sensor harness on the slider 35, Figure 4 As shown, in this embodiment, a mounting groove 350 is provided on the slider 35 , and the mounting groove 350 penetrates the slider 35 along the sliding direction of the slider 35 , and 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 body 3501 and is wound around the winding spring 7, parts of the sensor harness located on the second slot body 3501 and the winding spring 7 are partially removed from the wire sheath.

[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 1aAs 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. The transition section 202 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 out of the front end of the first sensor protection tube 2. A spiral transition section 202 is provided on the extension section 201 of the first sensor protection tube 2 extending out of the protection long tube 1, and the position of the transition section 202 is the bending position of the second sensor protection tube 10. In this embodiment, the transition section 202 can be formed by cutting the extension section 201, and the transition section 202 can be bent at any angle without being broken, so that the extension section 201 of the first sensor protection tube 2 can be prevented from being broken while protecting the second sensor protection tube 10.

[0123] like Figure 6 As shown, in order to further protect the first sensor protection tube 2, the protection tube tooling in this embodiment also includes a coated stent 9, which is sleeved and fixed on the front end of the protection long tube 1, and the first sensor protection tube 2 is inserted into the coated stent 9. When the ultrasonic emission part is bent back, the coated stent 9 can prevent the first sensor protection tube 2 from separating from the bent part, causing damage such as breaking of the first sensor protection tube 2. In this embodiment, the coated stent 9 can adopt a cardiovascular stent in the relevant technology, and its specific structure is not limited in this embodiment.

[0124] In this embodiment, the length of the stent graft 9 should satisfy the following conditions: the front end of the stent graft 9 is sleeved on the curved portion of the intraoperative ultrasound probe, and the front end of the stent graft 9 is bent during the bending of the curved portion. By sleeved the front end of the stent graft 9 on the curved portion, the first sensor protection tube 2 can be fitted to the curved portion of the intraoperative ultrasound probe as much as possible, thereby avoiding the first sensor protection tube from breaking during the bending process. In this embodiment, the transition section 202 of the first sensor protection tube 2 extends out of the front end of the stent graft 9. The transition section 202 of the first sensor protection tube 2 extends out of the front end of the stent graft 9.

[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 coated stent 9 in this embodiment includes a large diameter section 90 and a small diameter section 91 , the large diameter section 90 is sleeved and fixed on the front end of the protective long tube 1 , the small diameter section 91 is extended from the front end of the extension section, and the transition section 202 is extended from the small diameter section 91 .

[0126] In another embodiment, in order to protect the first sensor protection tube 2, the membrane support 9 can be replaced by a heat shrink tube or other tubular structures that have a certain supporting capacity and can shrink.

[0127] In one embodiment, the long protection tube 1 , the first sensor protection tube 2 , and the second sensor protection tube 10 are all made of biocompatible materials, such as nickel-titanium.

[0128] 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 coated stent 9 in this embodiment includes a large diameter section 90 and a small diameter section 91 , the large diameter section 90 is sleeved and fixed on the front end of the protective long tube 1 , the small diameter section 91 is extended from the front end of the extension section, and the transition section 202 is extended from the small diameter section 91 .

[0129] In one embodiment, the long protection tube 1 , the first sensor protection tube 2 , and the second sensor protection tube 10 are all made of biocompatible materials, such as nickel-titanium.

[0130] like Fig.10 and Fig.11 As shown, an embodiment of the present invention provides an installation tool for an intraoperative ultrasound probe 4, which can be used in conjunction with the protection tube tool in the above embodiment to complete the assembly of the intraoperative ultrasound probe and the electromagnetic navigation sensor. The installation tool includes:

[0131] Base 11;

[0132] A mounting seat 12, the mounting seat 12 is fixed on the base 11, an assembly channel 18 is provided in the mounting seat 12, an assembly entrance 15 connected to the assembly channel 18 is provided on the mounting seat 12, and the assembly channel 18 is configured to accommodate the probe buckle 16;

[0133] 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 in a straight line along the axis of the intraoperative ultrasound probe 4. The pushing end 131 is configured to be able to connect with the clamping piece 17 and, under the action of the movable end 131, push the clamping piece 17 sleeved on the intraoperative ultrasound probe 4 to move toward the mounting seat 12, and sleeve the clamping piece 17 tightly on the probe buckle 16.

[0134] 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 intraoperative ultrasound probe 4, and then the navigation sensor installed on the probe buckle 16, such as the electromagnetic navigation sensor, can maintain a relatively fixed position relationship with the ultrasonic emitting part. Before using the installation tool, the navigation sensor and the probe buckle 16 need to be pre-assembled, and the pre-assembly process varies according to different probe buckle 16 structures. In one embodiment, Figures 17 to 19As shown, a slot 23 is provided in the probe buckle 16, and the navigation sensor is fixed on the slot 23. During installation, the clamping member 17 needs to be sleeved on the first protective tube 2, located between the probe buckle 16 and the film support 9, and then the front end of the intraoperative ultrasound probe 4 is inserted into the probe buckle 16 from the rear end of the probe buckle 16, and finally the clamping member 17 is pushed to be clamped on the rear end of the probe buckle 16, so that the probe buckle 16 is tightly clamped on the intraoperative ultrasound probe 4. The clamping member 17 and the rear end of the probe buckle 16 can be connected by a buckle, for example, a plurality of slots are provided at the rear end of the probe buckle 16, and a plurality of buckles are provided on the inner side of the clamping member 17, and after the clamping member 17 is sleeved on the rear end of the probe buckle 16, the buckle is clamped into the corresponding slot, so that the rear end of the probe buckle 16 is tightly clamped on the intraoperative ultrasound probe 4.

[0135] When the protective tube fixture in the above embodiment is used, the pre-assembly process includes: inserting the electromagnetic navigation sensor into the second sensor protective tube 10, and the electromagnetic navigation sensor extends a certain length from the front end of the second sensor protection tube, the sensor harness is located in the second sensor protection tube 10 and fixed to the second sensor protection tube 10, and the rear end of the sensor harness extends from the rear end of the second sensor protection tube 10. Then, the electromagnetic navigation sensor and the second sensor protection tube 10 are inserted into the first sensor protection tube 2 in the protective tube fixture, the front ends of the electromagnetic navigation sensor and the second sensor protection tube 10 extend a certain distance from the front end of the first sensor protection tube 2, and the rear end of the second sensor protection tube 10 extends into the sliding channel and the slide groove 34 in the first clamping fixture 32, and the rear end of the sensor harness extends from the second sensor protection tube, passes through the slider 35 and is wound around the winding spring 7, and then passes through the fixing seat 8 and passes through the rear end of the first clamping fixture 32. Then, the clamping member 17 is sleeved on the first sensor protection tube 2, and the clamping member 17 is located in front of the protective long 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.

[0136] To realize the above assembly process, Fig.10 and Fig.11 As shown, the installation tool in this embodiment mainly includes a base 11, a mounting seat 12 and a propulsion mechanism 13. Among them, the base 11 serves as a basic mounting structure, and the base 11 can be set as a long strip plate-like structure. Of course, it can also be other structural forms, which is not limited in this embodiment. The mounting seat 12 can be installed at the first end of the base 11 as a structure for accommodating the probe buckle 16. The mounting seat 12 is provided with an assembly channel 18 extending in the horizontal direction, and an assembly entrance 15 connected to the assembly channel 18 is provided at the rear end (right end) of the mounting seat 12.

[0137] After the pre-assembly is completed, the probe buckle 16 equipped with the navigation sensor can be first installed into the assembly channel 18, and then the clamping member 17 can be sleeved on the intraoperative ultrasound probe 4, and the front end of the intraoperative ultrasound probe 4 can be inserted into the probe buckle 16. At this time, the clamping member 17 is located behind the probe buckle 16 (such as Fig.11 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). Fig.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 under the action of the moving end 130.

[0138] Specifically, when assembling with the above-mentioned protection tube tooling, after completing the above-mentioned pre-assembly, the probe buckle 16 can be installed into the assembly channel 18, and the protection long tube 1 is placed on the base 11. The base 11 is provided with a corresponding support structure to support the protection long tube 1. The handle fixing assembly 3 at the rear end of the protection long tube 1 is located behind the base 11, and then the handle fixing assembly 3 is adjusted to install the intraoperative ultrasound probe 4 from the second installation channel 38 of the handle fixing assembly 3. The front end of the intraoperative ultrasound probe 4 is inserted into the probe buckle 16 through the protection long tube 1 and the clamping piece 17. Finally, the clamping piece 17 is pushed by the propulsion mechanism 13 to move on the intraoperative ultrasound probe 4 and sleeved on the probe buckle 16. The entire assembled device is as follows Fig.19 shown.

[0139] In one embodiment, the mobile end 130 can be arranged on the base 11 and driven by a corresponding driving mechanism to move linearly. Of course, the mobile end 130 may not be arranged on the base 11, and it can be assembled and used as an independent component during installation. The pushing end 131 is connected to the mobile end 130. In one embodiment, the pushing end 131 can move linearly along the radial direction of the intraoperative ultrasonic probe 4. During installation, the pushing end 131 can move linearly close to the intraoperative ultrasonic probe 4 and be located at the rear end of the clamping member 17. At this time, the front end face of the pushing end 131 is close to or fits the rear end face 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 mobile end 130. After the installation is completed, the pushing end 131 can move in the opposite direction to facilitate the removal of the intraoperative 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. In this embodiment, there is no limitation on the specific structure of the pushing end 131, and those skilled in the art can design it according to actual needs.

[0140] In summary, during assembly, the navigation sensor can be first installed on the probe buckle 16, and then the probe buckle 16 can be installed into the assembly channel 18 of the mounting seat 12 from the assembly entrance 15, and the clamping member 17 can be sleeved on the intraoperative ultrasound probe 4, and then the front end of the intraoperative ultrasound probe 4 can be inserted into the probe buckle 16 from the rear end of the probe buckle 16, and finally the propulsion mechanism 13 can move the moving end 130 toward the mounting seat 12, and at the same time, the pushing end 131 is connected to the clamping member 17, and when the moving end 130 moves During the process, 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 clamped on the intraoperative ultrasound probe 4, thereby achieving the technical effect of being able to conveniently and firmly sleeve the clamping piece 17 on the probe buckle 16 to stably clamp the probe buckle 16 on the intraoperative ultrasound probe 4, thereby solving the problem of lack of tooling that can firmly sleeve the clamping piece 17 on the probe buckle 16 in the related technology.

[0141] According to the structural characteristics of the ultrasonic emitting part of the intraoperative ultrasonic probe 4, there is an ultrasonic emitting window 41 on the ultrasonic emitting part, and the probe buckle 16 needs to have a notch to avoid the ultrasonic emitting window 41. In order to avoid the interference of the probe buckle 16 with the ultrasonic emission, it is necessary to open a launch avoidance groove 160 matching the ultrasonic emitting window 41 on the probe opening. Since in the above-mentioned installation process, the probe buckle 16 is pre-installed into the assembly channel 18, and then the ultrasonic emitting part is inserted into the probe buckle 16, it is necessary to avoid relative deflection between the ultrasonic emitting window 41 on the ultrasonic emitting part and the launch avoidance groove 160 on the probe buckle 16, that is, the relative position of the launch avoidance groove 160 and the ultrasonic emitting window 41 needs to be calibrated during the installation process.

[0142] To achieve this object, in one embodiment, Fig.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, and an assembly entrance 15 is provided on the fixed vertical plate 120;

[0143] The calibration mechanism 121 is provided with an assembly channel 18, such as Fig.13 As shown, the calibration mechanism 121 includes a fixing member 1211, and the fixing member 1211 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 the calibration mechanism 121;

[0144] 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 intraoperative ultrasound probe 4 to calibrate the relative position of the probe buckle 16 and the ultrasound emission window 41 of the intraoperative ultrasound probe 4 .

[0145] Specifically, the fixed vertical plate 120 is provided with two parts 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 slot 160 and the ultrasonic emission window 41, it is necessary to adjust the position of the other one based on one of them. 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 positions of the ultrasonic emission window 41 and the emission avoidance slot 160 are adjusted by rotating the ultrasonic probe 4 during the operation. 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 not moved during the operation, and the relative positions of the two are adjusted by rotating the probe buckle 16. Since the ultrasonic probe 4 during the operation has a certain length, it is inconvenient to rotate it. In the present invention, it is preferred to calibrate the position by rotating the probe buckle 16.

[0146] Therefore, the calibration mechanism 121 in this embodiment includes a fixing member 1211, which is provided in two groups and 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 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 it so as to calibrate the position of the probe buckle 16.

[0147] After the position of the probe buckle 16 is calibrated, the probe buckle 16 is fixed in the assembly channel 18. After the intraoperative ultrasound probe 4 is inserted, the relative position of the probe buckle 16 and the ultrasound emission window 41 needs to be calibrated. In this embodiment, the relative position of the probe buckle 16 and the ultrasound emission window 41 is calibrated by rotating the probe buckle 16 by the rotating seat 1210.

[0148] On the basis of the above-mentioned embodiment, in order to realize automatic calibration, it is expected that during the process of inserting the ultrasound probe 4 into the probe buckle 16 during the operation, the calibration mechanism 121 can drive the probe buckle 16 to rotate based on the ultrasound emission window 41 to calibrate the relative position of the two. Fig.13 and Fig.13b As shown, the calibration mechanism 121 in this embodiment further includes a rotating seat 1210 and an elastic pressing member, and the end of the rotating seat 1210 is rotatably connected to the fixed vertical plate 120 through a bearing;

[0149] An assembly channel 18 is provided in the rotating seat 1210 , and a fixing member 1211 is provided on the rotating seat 1210 , and one end of the fixing member 1211 extends into the assembly channel 18 to compress and fix the probe buckle 16 ;

[0150] The elastic pressing member is disposed on the rotating seat 1210 , and the elastic pressing member includes a first elastic portion 1213 and a first pressing portion 1212 . Under the action of the first elastic portion 1213 , the first pressing portion 1212 at least partially extends into the assembly channel 18 and is located on the assembly path of the ultrasonic emitting window 41 .

[0151] Specifically, in this embodiment, the rotating seat 1210 can rotate around the axis of the assembly channel 18 in the horizontal direction, and the fixing member 1211 is installed on the rotating seat 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 part 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 has a tendency to completely fit on 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 to the first pressing portion 1212 by the first elastic portion 1213 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 portion 1212 is completely attached to the ultrasonic emission window 41. At this time, the relative positions of the ultrasonic emission window 41 and the emission avoidance groove 160 meet the requirements.

[0152] In this embodiment, the emission avoidance slot 160 on the probe buckle 16 is not necessarily in a horizontal state after installation, and 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 sheet, etc., which is not limited in this embodiment.

[0153] like Fig.13a As shown, in one implementation of the fixing member 1211, in order to enable the fixing member 1211 to apply a certain pressure to the probe buckle 16 to calibrate the position of the probe buckle 16 during the installation of the probe buckle 16, the fixing member 1211 in this embodiment includes a second elastic portion and a second pressing portion arranged in the rotating seat 1210, and the second pressing portion at least partially extends into the assembly channel 18 under the action of the second elastic portion and is located on the assembly path of the probe buckle 16.

[0154] Specifically, in this embodiment, when the probe buckle 16 is installed into the assembly channel 18 at a certain deflection angle, the upper end of the side wall of one side of the launch avoidance groove 160 is higher than the upper end of the side wall of the other side, so the higher side will compress the second elastic part connected to the second pressing part to a greater extent after contacting the corresponding second pressing part, and similarly, the lower side will compress the second elastic part connected to the second pressing part to a relatively smaller extent after contacting the corresponding second pressing part. Therefore, the second elastic part with a greater compression amplitude will apply greater pressure to the corresponding second pressing part, thereby pushing the probe buckle 16 to rotate a certain angle in the assembly channel 18 until the compression amplitudes of the second elastic parts on both sides are close to or consistent, at which time the probe buckle 16 is in the correct position in the assembly channel 18, that is, the launch avoidance groove 160 is in a horizontal position.

[0155] In one embodiment of the second elastic portion and the second pressing portion, the second elastic portion includes a second spring, the second pressing portion 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 launch avoidance groove 160 on the probe buckle 16.

[0156] Specifically, in this embodiment, when the probe buckle 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 buckle 16, there is sliding friction between the lower end of the pressure column and the upper end surface of the side wall of the launch avoidance groove 160. In order to reduce the friction, a ball bearing can be provided at the lower end of the pressure column.

[0157] like Fig.13 and Fig.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 ;

[0158] 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 emitting window 41 .

[0159] In this embodiment, during the process of inserting the ultrasonic probe 4 into the probe buckle 16 during the operation, the second end of the pressing block 12120 abuts against the surface of the ultrasonic emission window 41 and compresses the first spring 12130. When the ultrasonic emission window 41 deflects, the force applied by the first spring 12130 to the pressing block 12120 will react to the rotating seat 1210, thereby driving the probe buckle 16 to rotate, and then calibrating the relative position of the emission avoidance groove 160 on the probe buckle 16 and the ultrasonic emission window 41.

[0160] 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 member 1214 is provided on the end of the pressure block 12120 away from the rotating shaft. The first rolling member 1214 can extend into the assembly channel 18 under the action of the first spring 12130 and against the ultrasonic emitting window 41.

[0161] Specifically, in this embodiment, the rear end of the pressing block 12120 is hinged to the inner side of the rotating seat 1210 through a rotating shaft, the first spring 12130 is arranged in the rotating seat 1210, and the lower end of the first spring 12130 abuts against the upper end surface of the front end of the pressing block 12120. The lower end surface of the front end of the pressing block 12120 is provided with a first rolling member 1214, which can be a ball or a bearing, and the friction force is reduced by the first rolling member 1214.

[0162] 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, Fig.10 As shown, a linear drive mechanism 19 is disposed on the base 11 in this embodiment, and the linear drive mechanism 19 is transmission-connected with the moving end 130 for driving the moving end 130 to move linearly.

[0163] In this embodiment, the linear drive mechanism 19 can be a screw transmission mechanism, a cylinder, a hydraulic cylinder, etc., which is not limited 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 moving end 130, and the screw 190 of the screw transmission mechanism rotates to drive the screw slider to move linearly, thereby driving the moving 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 intraoperative ultrasonic probe 4. During installation, the clamping member is controlled to move toward the intraoperative 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 moving end 130 to be fixed on the probe buckle 16.

[0164] In one embodiment of the linear drive mechanism 19, Fig.11As shown, the linear drive mechanism 19 includes a screw transmission mechanism and a guide shaft 21, and the screw transmission mechanism and the guide shaft 21 are both arranged on the base 11;

[0165] The movable end 130 is fixedly connected to the lead screw slider 193 of the lead screw transmission mechanism, and the movable end 130 is slidably sleeved on the guide shaft 21 .

[0166] In this embodiment, the guide shaft 21 is mounted on the base 11, and both ends of the guide shaft 21 can be fixed in the guide seat, and the guide seat is fixed on the base 11. The axis of the guide shaft 21 is parallel to the axis of the intraoperative ultrasound probe 4. The guide shaft 21 can guide the linear movement of the mobile end 130, and at the same time, the lead screw 190 of the lead screw transmission mechanism can drive the lead screw slider 193 to move linearly.

[0167] In one embodiment of the screw drive mechanism, Fig.11 As shown, the screw transmission mechanism includes a screw 190, a screw slider 193, a screw mounting seat 12 and a rocker wheel 191. The screw is rotatably connected to the screw mounting seat 192, and the screw slider 193 is threadedly connected to the screw 190.

[0168] Specifically, in this embodiment, the lead screw 190 is arranged in a direction parallel to the intraoperative ultrasound probe 4, and 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 a fixed axis 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 rocking wheel 191. When installed, the rocking wheel 191 can be operated to rotate to drive the lead screw 190 to rotate, thereby driving the lead screw slider 193 and the moving end 130 to move linearly.

[0169] To facilitate the movement of the clamping member 17, the movable ends 130 in this embodiment are arranged into two groups and are symmetrically distributed on both sides of the base 11, the guide shafts 21 are arranged into two and are respectively slidably connected to the movable ends 130 on both sides, the screw transmission mechanism is arranged between the two movable ends 130, and the two groups of movable ends 130 are fixedly connected to the screw slider 193.

[0170] Specifically, in this embodiment, the lead screw 190 is arranged between the two groups of moving ends 130, the lead screw slider 193 is threadedly connected to the lead screw 190, and the two sides of the lead screw slider 193 are fixedly connected to the two groups of moving ends 130 through a connecting plate. A group of pushing ends 131 are respectively arranged on the two groups of moving ends 130, and the two groups of pushing ends 131 are respectively located on the two sides of the intraoperative ultrasound probe 4 during installation, and the two groups of pushing ends 131 can be operated to synchronously move toward the intraoperative ultrasound probe 4 to connect with the two sides of the clamping member 17. In this embodiment, by providing two groups of moving ends 130 and two groups of pushing ends 131, the forces on the two sides of the clamping member 17 are balanced during installation to avoid offset blockage.

[0171] like Figures 11 to 15 As shown, in one embodiment of the moving end 130, the moving end 130 includes a moving seat 1300, the pushing end 131 also includes a third spring 1312, the clamping member includes a push rod 1311 and a clamping ring 1310, the push rod 1311 is slidably disposed in the moving seat 1300 and can be driven to move linearly, and the third spring 1312 is sleeved on the push rod 1311;

[0172] The front end of the push rod 1311 extends out of the movable end 130 and is fixedly connected to the clamp ring 1310 . The clamp ring 1310 is used to clamp on the intraoperative ultrasound probe 4 and abut against the rear end surface of the clamping member 17 . The rear end of the push rod 1311 extends out of the movable seat 1300 .

[0173] Specifically, during installation, the rear end of the push rod 1311 can be pulled outward to make the clamp ring 1310 located at the front end of the push rod 1311 move backward to make room for the installation of the intraoperative ultrasound probe 4. During this process, the push rod 1311 will compress the third spring 1312. Then the intraoperative ultrasound probe 4 is installed in the probe buckle 16, and the clamping member 17 is also sleeved on the intraoperative ultrasound probe 4. Then the push rod 1311 is released, and the clamp ring 1310 at the front end of the push rod 1311 moves toward the intraoperative ultrasound probe 4 under the action of the third spring 1312 and is clamped on the intraoperative ultrasound probe 4. At this time, the clamp ring 1310 is located at the rear end of the clamping member 17. Finally, the movable seat 1300 can be controlled to move. During the movement, the clamp ring 1310 pushes the rear end surface of the clamping member 17 to make the clamping member 17 move forward linearly on the intraoperative ultrasound probe 4 until it is sleeved on the probe buckle 16. After the installation is completed, the push rod 1311 can be pulled outward again to separate the clamp ring 1310 from the intraoperative clamping piece 17 and the intraoperative ultrasonic probe 4, so as to facilitate the removal of the intraoperative ultrasonic probe 4.

[0174] Since the inner diameter of the clamping member 17 is larger than the outer diameter of the intraoperative ultrasonic probe 4 during installation, the upper end of the clamping member 17 fits with the upper surface of the intraoperative ultrasonic probe 4 after the intraoperative ultrasonic probe 4 passes through the clamping member 17, so that the clamping member 17 and the intraoperative ultrasonic probe 4 are in an eccentric state, while the intraoperative ultrasonic probe 4 and the probe buckle 16 are in a concentric state. Therefore, in the process of pushing the clamping member 17 to move, the connection between the clamping member 17 and the probe buckle 16 is easily blocked. In addition, since the clamping member 17 is relatively thin, the clamping ring 1310 is easily slipped off the clamping member 17 in the process of pushing the clamping member 17 to move only by contacting the rear end surface of the clamping member 17, resulting in assembly failure.

[0175] For this reason, Fig.11aAs shown, in this embodiment, a positioning protrusion 13100 is provided on one end of the clamp ring 1310 close to the clamping member 17. The positioning protrusion 13100 is used to be clamped into and fit on the inner side of the clamping member 17 before pushing the clamping member 17 to locate the radial position of the clamping member 17.

[0176] Specifically, in the present embodiment, after the front end of the intraoperative ultrasound probe 4 passes through the clamping piece 17 and is inserted into the probe buckle 16, the clamping piece 17, due to its own weight, causes the upper end to fit with the upper surface of the intraoperative ultrasound 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 piece 17 so that the positioning protrusion 13100 is clamped into the clamping piece 17. Under the action of the positioning protrusions 13100 on both sides, the clamping piece 17 moves upward and is positioned to a position concentric with the intraoperative ultrasound probe 4. At this time, pushing the clamping piece 17 forward again can determine the precise connection between the clamping piece 17 and the probe buckle 16. In addition, because the positioning protrusion 13100 is clamped into the inner side of the clamping piece 17, the clamping ring 1310 and the clamping piece 17 are not easy to slip during the process of pushing the clamping piece 17 to move, thereby improving the stability of the connection process. Fig.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 a first position, and the first position is an open position of the clamp ring 1310;

[0177] like Fig.11 and Fig.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 of the clamping ring 1310 close to the rear end face of the clamping member 17.

[0178] Specifically, before installation, the movable seat 1300 is in the initial position, at which time the push rod 1311 can be manually pulled outward, and when the push rod 1311 is pulled to the first position, the locking structure 22 is triggered, and the push rod 1311 is locked in the first position by the locking structure 22. In this embodiment, the first position of the push rod 1311 corresponds to the open position of the clamp ring 1310, that is, when the clamp ring 1310 is in this position, the intraoperative probe can be installed. After the push rod 1311 is locked in the first position, the intraoperative ultrasound can be installed in the probe buckle 16, and then the movable seat 1300 can be controlled to move forward.

[0179] When the movable seat 1300 moves forward to the second position, the linkage structure 20 on the base 11 triggers the locking structure 22 in the movable seat 1300. At this time, the locking structure 22 releases the push rod 1311 under the action of the linkage structure 20, and the push rod 1311 moves inward under the action of the third spring 1312, so that the clamping ring 1310 moves toward the intraoperative ultrasound probe 4. Since the clamping ring 1310 needs to abut against the rear end face 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 seat 1300 when the projection of the clamping ring 1310 on the intraoperative ultrasound probe 4 is close to the rear end face of the clamping member 17.

[0180] 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. Fig.14 and Fig.16 As shown, a slot 1313 may be provided on the push rod 1311, and the locking structure 22 includes a latch rod 220 and a fourth spring 221 provided in the movable seat 1300, the latch rod 220 is hinged in the base 11, the fourth spring 221 is connected to the latch rod 220, and the first end of the latch rod 220 is engaged with the slot 1313;

[0181] The second end of the card rod 220 extends out of the lower end of the moving seat 1300 and corresponds to the linkage structure 20. When the moving 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.

[0182] 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 locking rod 220. Under the action of the fourth spring 221, the first end of the locking rod 220 is inserted into the slot 1313 to lock the push rod 1311. At this time, the second end of the locking rod 220 extends out of the lower end of the movable seat 1300.

[0183] During the movement of the moving seat 1300 to the second position, the second end of the clamping rod 220 gradually approaches the linkage structure 20. After the second end of the clamping rod 220 contacts the linkage structure 20, as the moving seat 1300 moves further, the clamping rod 220 rotates around the hinge point so that the first end of the clamping rod 220 gradually disengages from the clamping groove 1313. When the moving seat 1300 reaches the second position, the first end of the clamping rod 220 completely disengages from the clamping groove 1313. At this time, the push rod 1311 pushes the clamping ring 1310 forward under the action of the third spring 1312 and clamps on the intraoperative ultrasound probe 4.

[0184] like Fig.14As shown, in one embodiment, the clamping rod 220 may include two vertical parts and one horizontal part, and the two vertical parts are respectively fixed at the two ends of the horizontal part. The middle part of the horizontal part is hinged to the moving seat 1300 through a rotating shaft, the vertical part located at the front end of the horizontal part is used to be clamped and matched with the clamping groove 1313, and the vertical part located at the rear end of the horizontal part can extend out of the lower end of the moving seat 1300 and cooperate with the linkage structure 20, and the lower end of the fourth spring 221 is connected to the horizontal part.

[0185] In order to enable the first end of the locking rod 220 to automatically snap 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 on the push rod 1311 at the rear end of the locking slot 1313, and automatic locking can be achieved through the cooperation of the two inclined surfaces.

[0186] Based on the above implementation, Fig.11 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 .

[0187] Specifically, in this embodiment, the linkage blocks are arranged on both sides of the base 11 and correspond to the moving seat 1300. The upper surface of the linkage block includes a linkage slope 201 and a linkage plane 202. When the push rod 1311 is locked by the clamping rod 220, as the moving seat 1300 moves forward, the second end of the clamping rod 220 gradually approaches the linkage slope 201. When the second end of the clamping rod 220 contacts the linkage slope 201, as the moving seat 1300 moves further, the clamping rod 220 will rotate around the hinge point, so that the first end of the clamping rod 220 gradually falls off the clamping 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 completely disengages from the clamping groove 1313 to release the clamping ring 1310, and the clamping ring 1310 will be clamped on the intraoperative ultrasound probe 4 and located at the rear end of the clamping member 17. 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 to move toward the probe buckle 16 and is sleeved on the probe buckle 16 .

[0188] In order to reduce the friction between the second end of the clamping rod 220 and the linkage block, a second rolling member 222 is provided at the second end of the clamping rod 220 in this embodiment, and the second rolling member 222 is used to cooperate with the linkage inclined surface 201 and the linkage plane 202. The second rolling member 222 can be a ball or a bearing, etc., which is not limited in this embodiment.

[0189] It is understandable that the locking structure 22 and the linkage structure 20 in the present invention can be linked electrically in addition to mechanical linkage. Specifically, the locking structure 22 can lock the push rod 1311 and release the push rod 1311 in an electrically powered manner, for example, the locking structure 22 is an electromagnetic lock, etc. During the movement of the moving seat 1300, the position of the moving seat 1300 can be detected by a corresponding displacement sensor, and when the moving seat 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.

[0190] In order to better push the clamping member 17, as Fig.14 As 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 cooperate with the plug-in.

[0191] Since the intraoperative ultrasound probe 4 has a longer insertion tube, the intraoperative ultrasound probe 4 can be horizontally connected to the probe buckle 16, such as Fig.10 As shown, in this embodiment, a plurality of support seats 14 are further provided on the base 11 , and support grooves are provided on the support seats 14 , and the support grooves are used to support the intraoperative ultrasound probe 4 .

[0192] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Within the spirit and principle of the present invention, any modification, equivalent replacement, improvement, etc. made shall be included in the protection scope of the present invention.
