[0052] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0053] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0054] In the embodiment of the utility model, at least part of the connection lines of the laparoscopic probe device 100 of the laparoscopic system adopt a normalized design, which can reduce the number of cables in the operating room, alleviate the problem of difficult cable handling in the operating room, and facilitate the doctor's operation. In addition, the laparoscopic probe has a built-in magnetic navigation sensor 125, which can locate the spatial position of the sound head, which is conducive to the doctor's accurate operation of the probe device and improves the efficiency of the operation.

[0055] The "proximal end" and "distal end" that appear in this article are conventional terms in the medical field. For a device to be operated, the proximal end is the end close to the device operator, and the distal end is the end away from the device operator. Figure 1 The proximal and distal ends are indicated by arrows.

[0056] Embodiments of the laparoscopic system of the present invention:

[0057] In one embodiment, please refer to Figure 1 The laparoscopic system includes a laparoscopic probe device 100 and a host. The laparoscopic probe device 100 is connected to the host via a connecting line. The host includes an ultrasound host 210 and a magnetic navigation control host 220.

[0058] The laparoscopic probe device 100 includes a handle part 110 for the doctor to hold and operate, and an insertion part 120 for inserting into a living body. In a specific embodiment, the insertion part 120 includes an ultrasonic head 124 and a magnetic navigation sensor 125. The insertion part 120 can respectively rely on the ultrasonic head 124 and the magnetic navigation sensor 125 to achieve ultrasonic detection and ultrasonic head positioning. In order to achieve the ultrasonic detection function, the ultrasonic head 124 needs to be connected to the ultrasonic host 210; in order to achieve the ultrasonic head positioning function, the magnetic navigation sensor 125 needs to be connected to the corresponding magnetic navigation control host 220. The ultrasonic host 210 and the magnetic navigation control host 220 can be arranged separately, such as Figure 1 In some other embodiments, the ultrasound host 210 and the magnetic navigation control host 220 may also be integrated, that is, arranged on the same device.

[0059] It should be noted that the magnetic navigation sensor 125 can adopt an existing structure in the relevant field, such as a coil. When in use, the magnetic navigation sensor 125 can cooperate with a magnetic field generator located outside the object under examination and a magnetic navigation control host 220 to detect the spatial position of the ultrasound head 124 by relying on electromagnetic signals.

[0060] The number of the magnetic navigation sensors 125 may be more than two, including a first sensor 126 and a second sensor 127 .

[0061] Please refer to Figures 2 to 7 In a specific embodiment, the number of the magnetic navigation sensors 125 may be two, namely a first sensor 126 and a second sensor 127. The two magnetic navigation sensors 125 may be located on two different planes parallel to the axis of the insertion component 120, such as Figures 4 to 7 The first sensor 126 and the second sensor 127 may also be located on a plane parallel to the axis of the insertion member 120, such as Figure 2 and Figure 3 In some other embodiments, the number of the magnetic navigation sensors 125 may be greater than two, and the relative position relationship of each magnetic navigation sensor 125 may also be determined as required.

[0062] In order to facilitate position detection, in one embodiment, the two magnetic navigation sensors 125 have an angle θ, 0°≤θ≤90°. For example, the angle between the first sensor 126 and the second sensor 127 can be 60°, or 15°, 30°, 45°, 75°, etc., or any other angle value between 0 and 90 degrees. The angle between the two magnetic navigation sensors 125 is the angle between the axes of the two magnetic navigation sensors 125. Taking the magnetic navigation sensor 125 in the form of a coil as an example, the angle between the axes of the two coils is the angle between the magnetic navigation sensors 125.

[0063] An insertion component 120 of a related laparoscopic probe device 100 may include a sound head section 121, a bending section 122, and a main body section 123. The sound head section 121 is provided with an ultrasonic head 124, which can realize ultrasonic detection. The bending section 122 can realize the bending of the distal end of the insertion component 120. The main body section 123 is mainly used to achieve the required insertion depth. The bending of the bending section 122 can be achieved by relying on the control of the handle component 110. Specifically, a pair of traction ropes can be arranged in the bending section 122. The pair of traction ropes are located on opposite sides of the bending section 122. The proximal ends of the two pairs of traction ropes are connected to the driving mechanism in the handle component 110. By tightening one of the traction ropes and loosening the other traction rope, the bending section 122 can be bent toward the side where the traction rope is tightened. In the case where two pairs of traction ropes are arranged in the bending section 122, the bending section 122 can realize bidirectional bending in a first plane through one pair of traction ropes, and can also realize bidirectional bending in a second plane through another pair of traction ropes. The first plane is perpendicular to the second plane. In addition, the driving mechanism in the handle component 110 can be driven by an operating lever or a dial outside the handle component 110, or can be electrically controlled by a button, or can be remotely electrically controlled by a host.

[0064] In order to realize the installation of the magnetic navigation sensor 125, in one embodiment, the magnetic navigation sensor 125 can also be arranged at the far end of the bending section 122, for example Figures 2 to 5 shown.

[0065] In some other embodiments, please refer to Figure 6 , Figure 7 The inserting component 120 includes a sound head section 121, a transition section 128, a bend section 122, and a main body section 123 arranged in sequence from the distal end to the proximal end. The magnetic navigation sensor 125 is arranged on the transition section 128, and the transition section 128 includes a shell, and the distal end and the proximal end of the shell are respectively fixedly connected to the sound head section 121 and the bend section 122, and the connection method is not limited, for example, it can be bonding, welding, threaded connection, etc. The provision of the transition section 128 facilitates the integration of the magnetic navigation sensor 125 on the inserting component 120. In some other embodiments, the magnetic navigation sensor 125 can also be arranged on the sound head section 121.

[0066] In order to realize the connection between the ultrasound head 124 and the ultrasound host 210 and the connection between the magnetic navigation sensor 125 and the magnetic navigation control host 220, the laparoscope system further includes a handle connecting line 130 connected to the handle component 110, a probe connector 140 connected to the handle connecting line 130, and a branch connecting line 150 connected to the probe connector 140. The probe connector 140 is provided with a plug-in portion 141 for connecting to an adapter device, and is also provided with at least one branch lead-out portion 142, and the branch lead-out portion 142 is connected to the branch connecting line 150. By providing the probe connector 140 and the branch connecting line 150, the handle component 110 of the laparoscopic probe device 100 can only lead out one normalized connecting line, that is, more than two wires used to connect different functional modules are aggregated into a bundle of connecting lines, and then the corresponding other connection requirements are realized through the branch connecting line 150 after reaching the probe connector 140, thereby reducing the number of connecting lines directly led out from the handle component 110, which is conducive to avoiding the influence of complicated cables on the doctor's operation.

[0067] In a specific embodiment, there is one handle connection line 130 connected to the handle component 110, and the handle connection line 130 includes an outer skin 131, a first wire 132 and a second wire 133, and the first wire 132 and the second wire 133 are both arranged in the outer skin 131. The first wire 132 and the second wire 133 are respectively connected to different functional modules of the laparoscopic probe device 100 for realizing current conduction, for example, they can be respectively connected to the above-mentioned ultrasonic head 124 and the magnetic navigation sensor 125. In some other embodiments, more than two handle connection lines 130 connected to the handle component 110 can be provided, but at least one of the handle connection lines 130 adopts the above-mentioned normalized connection line.

[0068] The number of wires included in the first wire 132 and the second wire 133 is not limited and can be designed according to the working requirements of the corresponding functional module. In addition, at least one of the first wire 132 and the second wire 133 can be integrated into a bundle and have its own outer skin. For example, the first wire 132 has a first outer skin, which wraps a plurality of wires, and the second wire 133 has a second outer skin, which wraps a plurality of wires. The first wire 132 and the second wire 133 are wrapped in the outer skin 131 of the handle connecting wire 130. Of course, the first wire 132 and the second wire 133 can also be dispersed in the outer skin 131 of the handle connecting wire 130 in a manner of multiple wires in parallel.

[0069] Please refer to Figure 1In one embodiment, the handle connecting wire 130 is connected to the proximal end of the handle component 110 and is located in the same straight line as the insertion component 120, and the distal ends of the first wire 132 and the second wire 133 are both connected to the corresponding functional modules at the distal end of the insertion component 120, the middle parts of the first wire 132 and the second wire 133 pass through the handle component 110, and the proximal parts of the first wire 132 and the second wire 133 are connected to the probe connector 140.

[0070] It should be noted that, in some other embodiments, the handle connection line 130 may also be connected to other parts of the handle component 110, such as the radially outer side of the handle component 110. In addition, the functional modules such as the ultrasonic head 124 and the magnetic navigation sensor 125 at the distal end of the insertion component 120 may be first connected to the circuit board or adapter in the handle component 110 through a corresponding wire, and the ends of the first wire 132 and the second wire 133 away from the probe connector 140 may be connected to the above-mentioned circuit board or adapter in the handle component 110.

[0071] In one embodiment, the plug-in portion 141 on the probe connector 140 is used to connect to the adapter device, the ultrasound host 210. The plug-in portion 141 can be in the form of a male connector or a female connector. Correspondingly, an adapter female connector or male connector is correspondingly provided on the ultrasound host 210. According to the connection requirements, the number of contacts in the probe connector 140 can be arranged as required, and the contacts can adopt existing structures in the field, for example, a pin-and-socket form, or a leaf spring form.

[0072] In one embodiment, a branch line plug structure 143 is provided on the probe connector 140, and the branch line lead-out portion 142 is formed by the branch line plug structure 143. The branch connection line 150 can be connected to the probe connector 140 through the branch line plug structure 143. When in use, the branch connection line 150 can be selectively connected or omitted according to needs, which is not only convenient for use, but also convenient for storage and cable arrangement. Of course, when the branch connection line 150 is omitted, the functional module corresponding to the branch connection line 150 will not work. For example, in the illustrated embodiment, the branch connection line 150 is connected to the second wire 133, and the second wire 133 is connected to the magnetic navigation sensor 125. If the branch connection line 150 is omitted, the magnetic navigation sensor 125 will not work, but the ultrasound head 124 can still work normally.

[0073] It should be noted that the functional modules connected to the first wire 132 and the second wire 133 are not limited. For example, the functional modules connected to the two can be swapped. At the same time, the structures of the plug-in part 141 and the branch lead-out part 142 can be adaptively adjusted as needed to meet the electrical connection requirements of the corresponding functional modules.

[0074] In order to further facilitate the use of the branch connection line 150, the end of the branch connection line 150 away from the probe connector 140 is connected to a branch line connector 151, and the branch line connector 151 can be plugged into an adapter device. For example, when the branch connection line 150 is used to connect the magnetic navigation sensor 125, the end of the branch connection line 150 away from the probe connector 140 can be plugged into the magnetic navigation control host 220.

[0075] In some other embodiments, the branch connection line 150 may also be fixed to the probe connector 140, for example, so that the corresponding second wire 133 only passes through the probe connector 140 and is directly led out from the housing of the probe connector 140. For another example, the second wire 133 may be connected to a circuit board or an adapter in the probe connector 140, and the branch connection line 150 is connected to the circuit board or the adapter in the probe connector 140, and then is led out from the housing of the probe connector 140. Figure 8 shown.

[0076] In one embodiment, the branch line lead-out portion 142 and the plug-in portion 141 are arranged on opposite sides of the probe connector 140, which can form a larger connector arrangement space and facilitate the plugging of the branch connection line 150. Of course, in some other embodiments, the branch line lead-out portion 142 can also be arranged at other parts of the probe connector 140, such as a side of the probe connector 140 away from the handle connection line 130, such as Fig. 9 shown.

[0077] An embodiment of a probe device in the utility model:

[0078] In an embodiment of a probe device, the probe device includes a handle component 110, an insertion component 120, a handle connection line 130, a probe connector 140, and a branch connection line 150. The handle component 110, the insertion component 120, the handle connection line 130, the probe connector 140, and the branch connection line 150 may be the same as the laparoscopic probe device 100 described above.

[0079] In the above embodiment of the laparoscopic probe device 100, the normalized handle connecting line 130 is used for the laparoscopic probe device 100, and the functional modules connected to the first wire 132 and the second wire 133 in the handle connecting line 130 are respectively the ultrasonic head 124 and the magnetic navigation sensor 125. An embodiment of a probe device may have at least one of the following differences from the above laparoscopic probe device 100: First, the normalized handle connecting line 130 may also be used for other probe devices other than the laparoscopic probe device 100, such as for a thoracoscope, a hysteroscope, etc. Second, the functional modules connected to the first wire 132 and the second wire 133 in the handle connecting line 130 may also be other modules, for example, the first wire 132 and the second wire 133 may be connected to the lighting module and the camera module, respectively, and for another example, the first wire 132 and the second wire 133 may be connected to the camera module and the magnetic navigation sensor, respectively. In addition, in some other embodiments of a probe device, the branch connecting line 150 can also be fixed on the adapter device. For example, the branch connecting line 150 can be fixed on the magnetic navigation control device, and the end of the branch connecting line 150 used for connecting to the probe connector 140 is provided with a branch plug 152, and the branch plug 152 can be connected to the probe connector 140 in a plug-in manner.

[0080] In some other embodiments, regardless of the type of probe device, the number of handle connecting wires 130 on the handle component 110 may be more than two, wherein at least one handle connecting wire 130 includes an outer skin 131 and the first wire 132 and the second wire 133, which can also reduce the number of cables.

[0081] By providing a probe connector 140 and a normalized handle connecting line 130, and providing a branch connecting line 150 connected to the probe connector 140, the number of cables directly connected to the handle component 110 of the probe device can be reduced, but the normalized handle connecting line 130 can still be used to connect different functional modules to the host, which can provide a more suitable environment for doctors' operations and help prevent the cables from being pulled and loosened or damaged, thereby avoiding unexpected effects on patients.

[0082] An embodiment of a laparoscopic probe device in the utility model:

[0083] The structure of the laparoscopic probe device is the same as that of the laparoscopic probe device 100 in the above-mentioned embodiment of the laparoscopic system, and will not be described in detail here.

[0084] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
