Fig. 1 is a schematic perspective view of an adjustment device for endoscopic surgery according to an embodiment of the present application. As shown in fig. 1, the adjusting apparatus 100 for endoscopic surgery includes a fixing member 110, a slide rail 120, and at least two slide tables 130. The fixing member 110 is provided with a connecting portion 111 for connecting to the puncture instrument 400 for endoscopic surgery. The slide rail 120 is disposed on the fixing member 110. At least two sliding tables 130 are provided with through holes 132 for connecting pipes 200 to pass through. The connection tube 200 is used to connect an endoscope 500 or a surgical actuator 600 for endoscopic surgery. The two or more sliding tables 130 are slidably disposed on the sliding rail 120, and the two or more sliding tables 130 can be locked with respect to the sliding rail 120.

The connecting portion 111 and the fixing member 110 may be an integral structure, the connecting portion 111 may also be fixedly connected to the fixing member 110 by welding, bonding, or the like, and the connecting portion 111 may also be connected to the fixing member 110 by screwing, snapping, or the like. The connection mode between the connection portion 111 and the puncture instrument 400 may be a fixed connection or a detachable connection, and the connection between the connection portion 111 and the puncture instrument 400 is specifically referred to in the following. The shape of the fixing member 110 may be a flat plate (e.g., a square plate, a rectangular plate, a fan-shaped plate, or other irregular-shaped plate), and the shape of the fixing member 110 may also be a rectangular parallelepiped, a cylinder, or other irregular-shaped plate. The slide rail 120 can be connected to the fixing member 110 by a fixed connection (e.g., bonding, welding, etc.) or a detachable connection (e.g., screwing, clipping, etc.).

The number of the slide table 130 may be two, three, five, etc. The number of the sliding table 130 may be determined according to the number of the connection tubes 200, and the number of the connection tubes 200 may be specifically set according to the number of surgical instruments (such as the surgical actuator 600 and the endoscope 500) required for one operation. In some embodiments, the sliding rail 120 may be provided with a sliding groove 121, and the sliding table 130 may be provided with a sliding block that can be snapped into the sliding groove 121, and the sliding block can slide along the sliding groove 121, so that the sliding table 130 can slide along the sliding rail 120. Fig. 2 is a schematic connection diagram of a sliding rail and a sliding table of an adjusting device according to some embodiments of the present application. As shown in fig. 2, in order to enable the sliding table 130 to slide on the sliding rail 120 more smoothly, a pulley 131 may be disposed on the sliding table 130, and the pulley 131 is disposed in the sliding groove 121 and can slide along the sliding groove 121. In some embodiments, a groove may be disposed on the sliding table 130, the sliding rail 120 is accommodated in the groove, and the pulley 131 on the sliding table 130 can cooperate with the sliding groove 121 on the sliding rail 120.

In some embodiments, the inner diameter of the through hole of the sliding table 130 may be slightly larger than the outer diameter of the connection pipe 200. The connection tube 200 can move back and forth in the through hole 132 in the axial direction of the through hole 132 (i.e., the length direction of the connection tube 200), so that the position of the endoscope 500 or the surgical effector 600 on the connection tube 200 can be adjusted. In some embodiments, as shown in fig. 2, the vias 132 may be elongated, for example, the vias may be kidney-shaped holes. By providing the through-hole 132 in an elongated shape, the connection tube 200 can be made more easily movable.

In some embodiments, the endoscope 500 can include a camera and a light source, and the endoscope 500 can enter the body, illuminate the site to be treated, and photograph the site to be treated. The picture taken by the endoscope 500 can be transmitted to the external display screen in real time so that the operator can observe the region to be treated. The surgical implement 600 may be understood to be a device capable of performing endoscopic surgical procedures, such as tumor resection, wound closure, and the like. The surgical implement 600 may also be advanced into the body to perform a surgical procedure on a site to be treated.

In this embodiment, before the connecting tube 200 is inserted into the through hole 132 of the sliding table 130, the sliding table 130 can be moved to a position (e.g., a position where the through hole 132 is opposite to the puncture instrument 400) for facilitating the insertion of the connecting tube 200. Meanwhile, after the connecting tube 200 passes through the through hole 132 of the sliding table 130, the sliding table 130 can slide on the sliding rail 120 to adjust the position of the sliding table 130, and the position of the connecting tube 200 (e.g., the position of the other end of the connecting control assembly 300 of the connecting tube 200) can be adjusted by adjusting the position of the sliding table 130, so that subsequent surgical operations (e.g., the operation of the control assembly 300) are facilitated.

In some embodiments, the adjustment device 100 of the present application may include a locking mechanism capable of locking the slide table 130 on the slide rail 120. In some embodiments, the locking mechanism may include a first connecting hole and a latch provided on the sliding table 130, and a plurality of second connecting holes provided on the sliding rail 120 and arranged at intervals along the length direction of the sliding rail 120. When the sliding table 130 slides to a specific position, the latch can be inserted into the first connecting hole and the second connecting hole corresponding to the specific position, so as to prevent the sliding table 130 from sliding relative to the sliding rail 120. In other embodiments, the locking mechanism may include a dial rotatably connected to the sliding table 130, and a plurality of slots disposed on the sliding rail 120 and spaced along the length of the sliding rail 120, wherein the dial can be engaged with or disengaged from the slots when the dial rotates relative to the sliding table 130. When the poking sheet is in a state of being separated from the slot, the sliding table 130 can slide along the sliding rail 120, and when the sliding table 130 slides to a specific position, the poking sheet can be rotated to be clamped into the slot, so that the sliding table 130 is prevented from sliding relative to the sliding rail 120.

In some embodiments, the adjustment device 100 further comprises at least two flexible tubes 140. The flexible tube 140 is for the connection tube 200 to pass through. One end of flexible tube 140 communicates with through hole 132 of slide table 130, and the other end thereof is connected to connecting portion 111 and can communicate with puncture instrument 400 (e.g., puncture cannula 410 of puncture instrument 400). In some embodiments, the number of the flexible tubes 140 may be the same as the number of the sliding tables 130, so that the sliding tables 130 are connected with the flexible tubes 140 in a one-to-one correspondence. In other embodiments, the number of flexible tubes 140 may be more or less than the number of slipways 130. For example, one sliding table 130 may be connected to a plurality of flexible tubes 140, a plurality of connecting tubes 200 may be inserted into one sliding table 130, and a plurality of connecting tubes 200 may be inserted into different flexible tubes 140 on the same sliding table 130. After passing through the through hole 132 of the sliding table 130, the connection tube 200 can further pass through the flexible tube 140, and then the connection tube 200 passes through the puncture instrument 400 (e.g., passes through the puncture cannula 410 of the puncture instrument 400) and enters the human body, so that the endoscope 500 and/or the surgical actuator 600 connected to the connection tube 200 can enter the human body and reach the site to be treated. In one aspect, flexible tube 140 may serve as a guide for connecting tube 200 inserted therein to allow connecting tube 200 to be more easily inserted into puncture instrument 400. On the other hand, the flexible tube 140 can prevent the different connection tubes 200 from interfering with each other during the endoscopic surgery.

In some embodiments, the slide rail 120 may be linear. Further, when the slide rail 120 has a linear shape, the distance from the connection portion 111 of the flexible tube 140 to the two ends of the slide rail 120 may be equal. Fig. 3 is a schematic structural diagram of a fixing member and a slide rail of an adjusting device according to some embodiments of the present application. In other embodiments, as shown in fig. 3, the sliding rail 120 may have a circular arc shape, and the inner arc surface of the circular arc shape faces the connecting portion 111. By designing the slide rail 120 into a circular arc shape, the length difference of each flexible tube 140 can be shortened, the bending degree of the flexible tube 140 in the sliding process of the sliding table 130 is reduced, and the sliding of the sliding table 130 is prevented from being influenced by the mutual interference between different flexible tubes 140. In the present embodiment, as shown in fig. 3, the fixing portion 311 may be provided in a shape of a fan, the connecting portion 111 may be provided at an end of the fan near a center of the fan, and the slide rail 120 may be provided at an end of the fan near a circular arc. Further, the shape of the slide rail 120 may conform to the shape of a circular arc of a sector.

In some embodiments, the distance from each point of the arc to the junction of the connection 111 and the flexible tube 140 is equal. In the present embodiment, the length of the flexible tube 140 may be substantially equal to the distance from each point of the circular arc to the connection point of the connection part 111 and the flexible tube 140. With this arrangement, the lengths of the respective flexible tubes 140 can be set to be the same, the flexible tubes 140 are hardly bent during the sliding of the slide table 130, and interference between different flexible tubes 140 does not occur during the sliding of the slide table 130.

The control assembly 300 is connected to the other end of the connection pipe 200. The control assembly 300 can push or pull the connection pipe 200 in the length direction of the connection pipe 200 (i.e., the axial direction of the through hole 132 of the slide table 130) to control the connection pipe 200 to move in the length direction of the connection pipe 200. Puncture instrument 400(Trocar) is a device used in endoscopic procedures (e.g., laparoscopic procedures) to penetrate body tissues (e.g., the entire abdominal wall) and establish a passageway between the exterior and the body (e.g., the abdominal cavity). Puncture instrument 400 may be configured to allow passage of a surgical instrument (e.g., connecting tube 200, endoscope 500, surgical effector 600, etc.) therethrough to allow access of the surgical instrument into a body (e.g., an abdominal cavity). In some embodiments, control assembly 300 can also be used to control the bending of the front end of connecting tube 200 and to control the performance of surgical procedures by surgical effector 600, as described in more detail below.

In some embodiments, the endoscopic surgical device includes at least two control assemblies 300. For example, an endoscopic surgical device can include two, three, or five, etc. control assemblies 300. Specifically, the number of the control assemblies 300 may be determined according to the number of the connection pipes 200. The number of the control assemblies 300, the number of the connecting pipes 200, and the number of the sliding tables 130 may be the same, the connecting pipes 200 and the control assemblies 300 may be connected in a one-to-one correspondence, and the connecting pipes 200 and the sliding tables 130 may be disposed in a one-to-one correspondence. With such an arrangement, one sliding table 130 can be correspondingly inserted into one connecting pipe 200, and one control assembly 300 can also correspondingly control the movement of one connecting pipe 200, so that the operation of an operator can be facilitated. In other embodiments, the number of the connection pipes 200 may be greater than the number of the sliding table 130. The number of connection tubes 200 may also be greater than the number of control assemblies 300. For example, one control assembly 300 may be used to control the movement of a plurality of connecting tubes 200.

Through the arrangement, the occupied space of the endoscopic surgery equipment is reduced as much as possible, and meanwhile, the operator can be ensured to better observe the part to be treated when performing endoscopic surgery. Meanwhile, the two surgical actuators 600 can be matched with each other, so that the implementation of surgical operations (such as tumor resection or suture and the like) can be facilitated, and the surgical efficiency is improved. In some preferred embodiments, connecting tube 200 connecting endoscope 500 may be located between two connecting tubes 200 connecting surgical implements 600. In other embodiments, the number of connectors 200 may be other, for example, the endoscopic surgical device may include four, five, seven, etc. connectors 200. By way of example only, when the endoscopic surgical device includes five connecting tubes 200, four of the connecting tubes 200 each have one end for connection to a surgical actuator 600 and another connecting tube 200 has one end for connection to an endoscope 500.

In some embodiments, one end of the connection tube 200 can be bent, and the control assembly 300 includes a bending control mechanism 310 for controlling the bending of the one end of the connection tube 200. The bending of the connection pipe 200 may be achieved by various structures. For example, the connection pipe 200 may include a spring pipe; for another example, the connection tube 200 may include a snake bone structure. Controlling the one end of the bending tube to be bent by the bending control mechanism 310 can facilitate adjustment of the irradiation and photographing positions of the endoscope 500 when the connection tube 200 is connected to the endoscope 500, and can facilitate adjustment of the operation position of the surgical actuator when the connection tube 200 is connected to the surgical actuator 600.
