特别地，本公开涉及拴系式腹腔镜探针，该拴系式腹腔镜探针经由套管针(trocar)插入，在此之后另一腹腔镜工具可以插入套管针中以操纵该探针。
PCT/GB2019/050305, filed Feb. 13, 2019; which claims priority from GB Patent Application No. 1801926.5, filed Feb. 6, 2018, the entire contents of which are hereby incorporated by reference in their entirety for all purposes.
本文所描述的腹腔镜探针适合用于探测在手术前对受试者施用的放射性药物发出的辐射。
BACKGROUND OF THE INVENTION
腹腔镜外科手术，也称为微创外科手术(minimally-invasive surgery)或锁孔外科手术(keyhole surgery)，是一种在受试者身体中使用小切口(通常0.5-1.5cm)执行操作的外科手术技术。
Laparoscopic surgery, also called minimally-invasive surgery or keyhole surgery, is a surgical technique in which operations are performed using a small incision (usually 0.5-1.5 cm) in the body of a subject.
腹腔镜外科手术相对比于开腔(open)外科手术提供了许多临床益处，例如，由于切口更小，使得疼痛降低和出血减少，并且患者的恢复时间减少。
Laparoscopic surgery provides a host of clinical benefits over open surgery, for example pain and hemorrhaging are reduced due to smaller incisions, and recovery times for the patient are reduced.
为了对受试者进行腹腔镜外科手术，在受试者身体上开一个小切口，并将套管针放入切口中。
In order to perform laparoscopic surgery on a subject, a small incision is made in the body of the subject and a trocar is placed into the incision.
套管针是一种医疗设备，其作为入口，用于后续将用于外科手术的其他器械放置到受试者的体腔中。
A trocar is a medical device that acts as a portal for the subsequent placement of other instruments into a cavity of the subject for use in the surgery.
套管针的尺寸，例如套管针的直径，提供了对可用于腹腔镜外科手术的器械的尺寸的限制，因为这些器械需要能够穿过套管针进入受试者体内。
The size of the trocar, for example the diameter of the trocar, provides a limit on the size of the instrument(s) that can be used in the laparoscopic surgery, as the instruments need to be able to pass through the trocar into the subject.
对于某些类型的腹腔镜外科手术，可能需要多种器械——如果同时需要这些器械并且每种器械占用一个端口，则可能需要多个切口，导致患者不适和患者恢复时间变慢。
For some types of laparoscopic surgeries, multiple instruments may be required—if these instruments are required at the same time and each take up a port, then multiple incisions may be required, leading to patient discomfort and slower patient recovery times.
有时，腹腔镜伽马(gamma)探针可用于放射性引导的腹腔镜手术。
Sometimes, a laparoscopic gamma probe may be used for radioguided laparoscopic procedures.
受试者可以在外科手术前接收放射性药物，该放射性药物被设计用于定位受试者体内的异常组织(如肿瘤)，并发射可被探针探测到的辐射。
A subject may receive a radiopharmaceutical in advance of surgery, the radiopharmaceutical designed to locate abnormal tissue such as tumors in the subject and to emit radiation detectable by a probe.
放射性药物是一种可用于诊断或治疗目的且包括被结合到分子的放射性同位素的药物。
A radiopharmaceutical is a drug that can be used for diagnostic or therapeutic purposes and comprises a radioisotope bonded to a molecule.
放射性药物将同位素(isotope)输送到具体的器官、组织或细胞，并根据其特性和用途进行选择。
The radiopharmaceutical conveys the isotope to specific organs, tissues or cells, and is selected for its properties and purpose.
许多放射性药物在本领域中是已知的，并且用于放射性引导的外科手术和其他手术。
Many radiopharmaceuticals are known in the art and are used for radioguided surgery and other procedures.
典型地包括由刚性杆支撑的伽马辐射探测器的腹腔镜伽马探测器可以通过套管针插入到受试者的体腔中，以试图定位辐射源，并从而定位任何异常组织。
A laparoscopic gamma probe, which typically comprises a gamma radiation detector supported by a rigid rod, may be inserted through a trocar into a cavity of the subject in an attempt to locate the source of the radiation and thereby locate any abnormal tissue.
然而，由于刚性杆在套管针内的移动受到限制，这种探针在体腔内的机动性有限。
However, such probes have limited maneuverability within the cavity due to the restriction of movement of the rigid rod within the trocar.
此外，这种腹腔镜探针会占尽整个套管针，因此如果外科手术需要另外的外科手术工具，则需要在受试者身体上的另外的切口。
Furthermore, such laparoscopic probes would use up an entire trocar, and so further incisions in the subject would be required if further surgical tools are required for the surgery.
本申请提供了克服如上所述的问题的解决方案。
The present application provides solutions to overcome problems such as those described above.
根据本发明的方面，提供了一种拴系式腹腔镜探针。
According to an aspect of the invention, a tethered laparoscopic probe is provided.
该拴系式腹腔镜探针用于通过套管针部署(deployment)到受试者的体腔中，以探测来自被施用给受试者的放射性药物的伽马辐射。
The tethered laparoscopic probe is for deployment through a trocar into a cavity of a subject to detect gamma radiation from a radiopharmaceutical administered to the subject.
腹腔镜探针包括探针头，该探针头被成形为用于通过套管针插入并被构造成可在体腔内自由移动。
The laparoscopic probe comprises a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity.
探针头包括细长壳体，该细长壳体包括用于抑制伽马辐射穿过探针头的辐射屏蔽，该辐射屏蔽具有用于允许伽马辐射通过的探测孔。
The probe head comprises an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation.
探针头还包括被布置在壳体内的伽马辐射探测器，该伽马辐射探测器被构造成探测通过壳体的探测孔的伽马辐射。
The probe head further comprises a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing.
探针头还包括用于在使用中促进对来自体腔内放射性药物的辐射源进行定位的装置。
The probe head further comprises means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity.
腹腔镜探针还包括拴系件(tether)，该拴系件被联接到探针头并用于在使用中拴系探针头通过套管针。
The laparoscopic probe further comprises a tether coupled to the probe head and for, in use, tethering the probe head through the trocar.
通过提供这种拴系式腹腔镜探针，腹腔镜探针可以通过套管针的端口部署，并且在使用中，不会占据端口的整个容量。
By providing such a tethered laparoscopic probe, the laparoscopic probe may be deployed through a port of a trocar and, in use, not take up the entire capacity of the port.
相应地，当腹腔镜探针被部署时，另外的器械可以用相同的套管针端口来使用。
Accordingly, further instrument(s) may be used with the same trocar port while the laparoscopic probe is deployed.
更有利的是，与包括将对探测器头的控制限制在四个自由度的刚性杆状结构的传统腹腔镜探针相比，本文描述的拴系式腹腔镜探针在使用中可以具有六个自由度。
Further advantageously, in comparison to traditional laparoscopic probes which comprise a rigid rod like structure limiting control of a detector head to four degrees of freedom, a tethered laparoscopic probe as described herein may, in use, have six degrees of freedom.
由于腹腔镜探针用于部署到体腔中，探针头必须足够小以穿过套管针的端口，该端口的直径可以是例如12mm。
As the laparoscopic probe is for deployment into a cavity, it is necessary that the probe head is small enough to pass through a port of a trocar, which may be, for example, 12 mm in diameter.
对探针头尺寸的这种限制意味着，一旦被部署，即使有辐射屏蔽，伽马辐射可以穿过探针头的侧面或后部，并触发伽马辐射探测器。
Such a restriction on the size of the probe head means that, once deployed, gamma radiation may pass through the side or rear of the probe head and setting off the gamma radiation detector, even with radiation shielding.
因此，在使用中，提供用于促进对来自体腔内放射性药物的辐射源定位的装置是有利的，因为它允许用户定位伽马辐射源。
To provide means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical in the cavity, is therefore advantageous as it allows a user to locate the source of gamma radiation.
如下文将进一步描述的，这样的装置可以由此向用户提供更大的保证，即，探测到的结果是穿过腹腔镜探针的探测孔而不是穿过侧面或后部的辐射。
As will be described further below, such means may thereby provide a greater assurance to the user that detections are the result of radiation passing through the detection aperture of the laparoscopic probe as opposed to through the side or rear.
在使用中，通过提供用于促进对来自体腔内放射性药物的辐射源定位的装置，探针的用户能够有效地定位受影响的组织。
By providing means for, in use, facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity, a user of the probe is able to locate the affected tissue efficiently.
伽马辐射探测器可以包括闪烁体，该闪烁体被构造成在使用中响应于接收到的伽马辐射而闪烁。
The gamma radiation detector may comprise a scintillator configured to scintillate, in use, in response to received gamma radiation.
伽马辐射探测器还可以包括光电探测器，以探测来自闪烁体的闪烁光。
The gamma radiation detector may further comprise a photodetector to detect the scintillated light from the scintillator.

The photodetector may comprise a silicon photomultiplier (“SiPM”).
光电探测器可以包括雪崩光电二极管(“APD”)。
The photodetector may comprise an avalanche photodiode (“APD”).
闪烁体可以包括铊活化碘化铯(Thallium activated Caesium Iodide)CsI:TI。
The scintillator may comprise Thallium activated Cesium Iodide, CsI:TI.
辐射屏蔽可以具有厚度，并且闪烁体可以具有半径，且辐射屏蔽的厚度和闪烁体的半径可以被选择为使得在使用中由伽马探测装置探测到的穿透辐射屏蔽的伽马辐射与入射到辐射屏蔽上的伽马辐射的比率小于或等于1∶1000，并且使得在使用中，伽马探测装置对通过探测孔入射的伽马辐射的灵敏度被最大化。
The radiation shielding may have a thickness, and the scintillator may have a radius, and the thickness of the radiation shielding and the radius of the scintillator may be selected such that, in use, the ratio of the gamma radiation permeating through the radiation shielding that is detected by the gamma detection means to the gamma radiation incident on the radiation shielding is less than or equal to 1:1000, and such that, in use, the sensitivity of the gamma detection means to gamma radiation incident through the detection aperture is maximized.
通过提供这种辐射屏蔽和闪烁体，探针定位辐射源的能力大大提高，因为这种比率适合于向用户保证，与辐射穿过探针头102的任何其他部分的可能性相比，任何探测到的辐射穿过腹腔镜探针的探测孔的可能性是高的。
By providing such radiation shielding and scintillator, the ability of the probe to locate the source of radiation is greatly improved as such a ratio is suitable to assure a user that the likelihood that any detected radiation passed through the detection aperture of the laparoscopic probe is high compared to the likelihood that the radiation passed through any other part of the probe head 102.
伽马辐射探测器可以包括半导体伽马辐射探测器。
The gamma radiation detector may comprise a semiconductor gamma radiation detector.
半导体辐射探测器可以包括碲镉锌(CZT)。
The semiconductor radiation detector may comprise Cadmium Zinc Telluride, CZT.

The means for facilitating the localization of a source of radiation from the radiopharmaceutical within the cavity may comprise a beta radiation detector arranged within the casing, between the detection aperture and the gamma radiation detector, and configured to detect beta radiation through the detection aperture of the radiation shielding.
也就是说，腹腔镜探针可以包括探针头，该探针头被成形为用于通过套管针插入，并且被构造成可在体腔内自由移动，该探针头包括：细长壳体，该细长壳体包括用于抑制伽马辐射穿过探针头的辐射屏蔽，该辐射屏蔽具有用于允许伽马辐射通过的探测孔；布置在壳体内的伽马辐射探测器，该伽马辐射探测器被构造成探测通过壳体的探测孔的伽马辐射；以及布置在壳体内的贝塔辐射探测器，该贝塔辐射探测器在探测孔和伽马辐射探测器之间，并且被构造成探测通过辐射屏蔽的探测孔的贝塔辐射。
That is, the laparoscopic probe may comprise a probe head shaped for insertion through the trocar and configured to be freely moveable within the cavity, the probe head comprising: an elongate casing comprising radiation shielding for inhibiting gamma radiation from passing through the probe head, the radiation shielding having a detection aperture for admitting gamma radiation; a gamma radiation detector arranged within the casing, the gamma radiation detector configured to detect gamma radiation through the detection aperture of the casing; and a beta radiation detector arranged within the casing, between the detection aperture and the gamma radiation detector, and configured to detect beta radiation through the detection aperture of the radiation shielding.

如图14所示，作业员P能够从装配支架30的上方通过窥视孔31c目视到第一固定部32a。
FIG. 15 illustrates a state that the operator P is viewing the insertion hole h2 of the first fixing portion 32a through the viewing hole 31c.
图15中表示了作业员P通过窥视孔31c目视到第一固定部32a的插孔h2的状态。
In FIG. 15, the first fixing portion 32a (the insertion hole h2) to be viewed is indicated by a hatched portion.
此外，该图15中以带影线的部分来表示了所目视到的第一固定部32a(插孔h2)。
As illustrated in FIG. 15, the operator P can easily perform an operation of fastening the fastening bolt 40 with respect to the first fixing portion 32a, in other words, an operation of inserting the fastening bolt 40 into the insertion hole h2 of the first fixing portion 32a and screwing the fastening bolt 40 in the mounting hole 12a.
如该图所示，作业员P利用窥视孔31c能够容易地进行针对第一固定部32a的紧固螺栓40的紧固作业，亦即将紧固螺栓40插入到第一固定部32a的插孔h2且螺合于安装孔12a的作业。
Further, during maintenance and the like of the vehicle, connection of the power train PT and the mounting bracket 30 by the fastening bolts 40 may be disconnected.
此外，在进行车辆的维修等时，有时会解除基于紧固螺栓40而连结的动力系PT和装配支架30之间的连结，该连结解除的作业可以在通过窥视孔31c来视觉认识与第一固定部32a相对应的紧固螺栓40的情况下来进行。
The operator can perform the disconnecting operation, while visually recognizing the fastening bolt 40 associated with the first fixing portion 32a through the viewing hole 31c.
基于紧固螺栓40而连接的动力系PT和装配支架30的组装体此后被安装于左右一对前纵梁4A、4B。
An assembly of the power train PT and the mounting bracket 30 connected by the fastening bolts 40 is, thereafter, mounted on the paired left and right front side frames 4A and 4B.
此外，紧固螺栓40进行的连结较为理想的是在动力系PT和装配支架30的组装体搭载到前纵梁4A、4B之前的状态下进行暂定紧固，在该组装体搭载在前纵梁4A、4B上之后进行正式紧固。
Fixation by the fastening bolts 40 is preferably performed by performing provisional fixation in a state before the assembly of the power train PT and the mounting bracket 30 is installed on the front side frames 4A and 4B, and performing final fixation after the assembly is installed on the front side frames 4A and 4B.
此处，在图3所示的俯视下，如前所述，符号α1表示左侧的装配构件22的位移起点。
In a plan view of FIG. 3, as already described, the reference sign α1 indicates the displacement starting point of the left mounting member 22.
此外，符号α2表示装配支架30的第一固定部32a和变速驱动桥12的连结部位。
Further, the reference sign α2 indicates a connecting portion between the first fixing portion 32a of the mounting bracket 30, and the transaxle 12.
上述的位移起点α1和连结部位α2是与发生前碰撞时的动力系PT的动作较大地相关联的部位。
The displacement starting point α1 and the connecting portion α2 are portions that are greatly related to movement of the power train PT in the event of collision from the front side.
此处，假定发生了车辆的前碰撞更详细而言发生了碰撞负荷从右斜前方输入到车身前侧面中相对于宽度中心偏靠于右侧(与动力系PT相同一侧)的位置的斜向碰撞(或SOL碰撞)。
Let us assume a case that vehicular collision from the front side, more specifically, oblique collision (or SOL collision), in which a collision load is input obliquely from the front right side to a position offset to the right side (to the same side as the power train PT) with respect to a center of the width of the front surface of the vehicle body, has occurred.
图4中，以符号F表示了在发生这样的斜向碰撞时所输入的来自右斜前方的碰撞负荷。
In FIG. 4, the reference sign F indicates a collision load, which is supposed to be input obliquely from the front right side in the event of such oblique collision.
碰撞负荷F被输入动力系PT后，装配支架30的连结于变速驱动桥12的连结部(固定部)中，强度相对较弱的第二至第四固定部32b至32d较早期被破坏，仅上侧且前侧的第一固定部32a还能够处于将变速驱动桥12和装配支架30连接着的状态。
When the collision load F is input to the power train PT, the second to fourth fixing portions 32b to 32d having a relatively small strength among the connecting portions (fixing portions) of the mounting bracket 30 with respect to the transaxle 12 are broken at an early stage, and a state that the transaxle 12 and the mounting bracket 30 are connected only by the fixing portion 32a on the upper front side is acquired.
由此，来自装配支架30的对抗动力系PT的对抗力(对顶力)便主要从与第一固定部32a相对应的装配支架30的前部(连结部位α2)进行作用。
Then, a reaction force (a pushing force) of the mounting bracket 30 against the power train PT mainly acts from a front portion (the connecting portion α2) of the mounting bracket 30, which corresponds to the first fixing portion 32a.
由此，在图4所示的俯视下，动力系PT便在以装配构件22的位移起点α1附近为中心进行横摆运动的情况下后退。
Thus, in a plan view of FIG. 4, the power train PT retracts, while performing yaw motion around the vicinity of the displacement starting point α1 of the mounting member 22.
基于在前碰撞时发生上述那样的横摆运动，动力系PT作为一个整体一边向车宽中央侧位移一边后退，从而被诱导到驾驶席和助手席之间。
When yaw motion as described above is generated in the event of collision from the front side, the power train PT as a whole retracts, while displacing toward the vehicle width center, and is guided to a position between the driver seat and the passenger seat.
换言之，上述横摆运动起到了防止或抑制动力系PT径直后退(朝向驾驶席或助手席的移动)的作用。
In other words, the yaw motion plays a role of preventing or suppressing the power train PT from linearly retracting (moving toward the driver seat or the passenger seat).
此外，动力系PT除了伴随上述那样的横摆运动的后退之外还会向下方位移。
Further, in addition to retraction accompanying the yaw motion as described above, the power train PT displaces downwardly.
如上所述，本实施方式中，装配支架30的顶壁部31以越接近动力系PT(越往右侧)高度越低的方式倾斜。
As described above, in the present embodiment, the top wall 31 of the mounting bracket 30 is inclined in such a way that a height of the top wall 31 decreases toward the power train PT (toward the right side).
这样的装配支架30的形状是在发生前碰撞时使动力系PT朝下方位移而较为理想的形状。
The above-described shape of the mounting bracket 30 is preferable in terms of displacing the power train PT downwardly in the event of collision from the front side.
发生前碰撞时动力系PT向上述那样的方向位移意味着动力系PT朝着位于前围板1的下端中央的隧道部7的前端的开口部7a移动。
Displacing the power train PT in the above-described direction in the event of collision from the front side means that the power train PT moves toward the opening portion 7a in the front end of the tunnel portion 7, which is located in the middle of the lower end of the dashboard panel 1.
因此，即使在动力系PT的后退量相当大的情况下，包含处于相对较高位置的变换器13在内的动力系PT也会以进入开口部7a的方式移动。
Therefore, even when a retraction amount of the power train PT is considerably large, the power train PT including the inverter 13, which is located at a relatively high position, moves in such a way as to enter the opening portion 7a.
由此，能够防止或者抑制动力系PT进入到车室3内的情况。
This prevents or suppresses the power train PT from entering the passenger compartment 3.
虽然图4中所假定的是碰撞负荷F从右斜前方输入到车身前面的右侧部分的情形，但是，上述那样的动力系PT的位移(朝向隧道部7的前端的开口部7a的位移)即使在碰撞负荷从径直前方输入到车身前面的右侧部分(相当于动力系PT的正前方的位置)的情况下也同样能观察到。
The above-described displacement of the power train PT (a displacement toward the opening portion 7a formed in the front end of the tunnel portion 7) is also observed in a case that a collision load is input linearly from the front side to the right portion of the front surface of the vehicle body (a position immediately in front of the power train PT).
此处，本实施方式的车辆的车身具有能够通用于不具备发动机的电动汽车和具备发电专用的发动机的增程器式电动汽车的结构。
The vehicle body of the vehicle according to the present embodiment has a structure sharable between an electric vehicle without an engine, and a range extended electric vehicle including an engine exclusively used for power generation.
但是，在增程器式电动汽车的情况下，不使用装配支架30。
However, in the case of a range extended electric vehicle, the mounting bracket 30 is not provided.
图16表示了动力系PT2搭载在增程器式电动汽车中的例子。
FIG. 16 illustrates an installation example of a power train PT 2 for use in a range extended electric vehicle.
该图16的例子中，在变速驱动桥12和装配构件22之间取代装配支架30而设置发动机15及通过该发动机15而进行发电的发电机16。
In the example of FIG. 16, in place of a mounting bracket 30, an engine 15, and a power generator 16 to be powered by the engine 15 are disposed between a transaxle 12 and a mounting member 22.
即，动力系PT2具有将马达11、变速驱动桥1、发动机15以及发电机16直列地连结而成的结构。
Specifically, the power train PT2 has a structure in which a motor 11, the transaxle 12, the engine 15, and the power generator 16 are connected in series.
图17至图19表示了本发明的第二实施方式。
FIGS. 17 to 19 illustrate a second embodiment according to the present invention.
本实施方式是为了在发生前碰撞时更切实地实现动力系PT一边进行横摆运动一边后退这一动作，而增加了以下的对策亦即使碰撞负荷输入到动力系PT的位置位于极力地离开装配构件22的位置的对策的实施方式。
