Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of directional words such as "upper, lower, left and right" is defined according to the directions indicated in the respective drawings, and "inner" and "outer" refer to the inner and outer of the contours of the respective parts themselves. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

The invention provides a push-away device for a transvaginal single-hole laparoscope, which mainly has the effect that in the process of gynecological operation, a push-away device 1 pushes away an intestinal canal through a vagina 3 to expose a pelvic cavity 2. As shown in fig. 1 and 2, the transvaginal single-hole laparoscopic push-aside apparatus 1 includes an outer tube 11 extending in a U-shape and a core tube 12 fitted around the inside of the outer tube 11, and the core tube 12 is disposed so as to be movable along the extending direction of the outer tube 11. The push-away device 1 further comprises a driving member 13 and a push-away member 14, the driving member 13 is arranged on the push-away device 1 and is connected with one end of the core tube 12 to drive the core tube 12 to move, and the push-away member 14 is arranged at the other end of the core tube 12. The push-away piece 14 has a retracted state in which the push-away piece 14 is retracted inside the outer sleeve 11 and a pushed-away state in which the push-away piece 14 extends out of the outer sleeve 11 and pushes away the intestinal tract to expose the pelvic cavity.

Through the above technical solution, that is, the outer casing 11 is extended in a U-shape, so that the operating site (driving member) can be kept away from the operator, specifically, the direction of the operator operating the driving member 13 to pull the movable core tube 12 is changed, so as to achieve the purpose of giving way to the operating area in front of the operator and facilitating the operation of the operation. As illustrated in figures 1 and 2, during the operation, the operator is positioned between the patient's legs (to the right in the figures), and the drive member 13 is positioned above the patient's abdomen, and no longer in front of the operator as in a straight tube laparoscope, due to the U-shaped extension of the outer cannula 11. In addition, the core tube 12 is pulled and moved by operating the driving piece 13 so that the pushing piece 14 retracts or extends out of the outer sleeve 11, and the intestinal tube can be pushed away when the outer sleeve 11 extends, so that the pelvic cavity operation area can be fully exposed under the condition that pneumoperitoneum is not established, and adverse effects on a patient caused by the establishment of the pneumoperitoneum are avoided.

According to an embodiment of the present disclosure, with continued reference to fig. 1 and 2, the push-away member 14 may include a mounting plate 141 and a plurality of push rods 142, the mounting plate 141 is fixedly connected to one end (the end for extending into the patient) of the core tube 12, and the push rods 142 are configured to be elastically mounted on the mounting plate 141 to be outwardly expandable. The push rod 142 is configured to elastically expand outwardly in a natural state, and to inwardly converge due to the constraint of the tube wall of the outer sleeve 11 when in a retracted state, and to re-expand outwardly due to the absence of the constraint of the outer sleeve 11 when in a pushed-away state, so as to achieve the purpose of pushing away the intestinal tube to expose the pelvic cavity.

Further, the end of the push rod 142 may be formed with a contact end 143 for increasing a contact area. The contact end 143 may be integrally formed with the push rod, i.e., both may be integrally formed by injection molding. The contact terminal 143 may be bowl-shaped or disc-shaped for the purpose of increasing the contact area. It should be noted that the increased contact area means that the contact area between the contact end 143 and the wall of the intestinal canal is increased to improve the stability of pushing the intestinal canal open.

In addition to the above-mentioned form of the push-away piece 14 configured to elastically expand outward, in other embodiments, for example, in the embodiment shown in fig. 3, the push-away piece 14 may also include a mounting disc 141 ' and a push rod 142 ', wherein the mounting disc 141 ' is connected to the core tube 12, unlike the above-mentioned embodiment, in this embodiment, the push rod 142 ' is petal-shaped, and one end of the push rod 142 ' is movably hinged on the outer sleeve 11. The mounting plate 141 'can force the petal-shaped push rods 142' to open along with the movement of the core tube 12.

According to an embodiment of the present disclosure, with continued reference to fig. 1 and 2, the driving member 13 may be a handle formed of a movable arm 131 and a stationary arm 132 hinged to each other, through which the core tube 12 passes, and such that the core tube 12 is driven to move when the movable arm 131 rotates about the hinge point. The movable arm 131 is pulled, and the movable arm 131 further pulls the core tube 12 to move. Furthermore, the movable arm 131 and the stationary arm 132 "of the" lever "can be designed reasonably by setting the position of the hinge point of the movable arm 131 and the stationary arm 132 reasonably to achieve the movement of the core tube 12 with the least effort.

Further, an elastic member 15, such as a compression spring, may be provided between the movable arm 131 and the stationary arm 132, and the elastic member 15 is provided with an elastic force that drives the movable arm 131 in a natural state to extend the push-away member 14 out of the outer tube 11. Here, as an example of the push rod having the push-away piece 14 elastically expanded outward, the movable arm 131 is pulled, the core tube 12 pulls the push-away piece 14 to retract the outer tube 11, and after releasing the hand, the movable arm 131 returns to the original position by the elastic restoring force of the elastic piece 15, and the core tube 12 pulls the push-away piece 14 to extend out of the outer tube 11. The advantage of this design is that the resilient member 15 maintains the pushed-open state of the ejector 14 without the operator having to hold the manually pushed-open state all the time, freeing manual effort.

Due to the presence of the spring element 15, the push-open element 14 is always in the pushed-open state extending out of the outer sleeve 11 without intervention of external forces, which makes it problematic how the pushed-open device 1 maintains the retracted state of the push-open element 14 in the non-use state. Still further, the push-away device 1 further includes a locking member 16 for fixing the relative positions of the movable arm 131 and the static arm 132 when the movable arm 131 and the static arm 132 approach each other and compress the elastic member 15, wherein the locking member 16 may be a lasso, or may be configured as a structure common in the locking field such as a buckle.

In other embodiments, it is also possible to use a simpler way of driving the movement of the core tube 12, for example, the driving member 13 is constructed as a structurally simpler push-pull rod, which, because the core tube 12 is located inside the outer jacket tube 11, needs to be arranged outside the outer jacket tube 11 for easy operation. The movement of the core tube 12 can be achieved by pushing and pulling.

As shown in fig. 1 and 2, the outer tube 11 has a flushing hole 17 at an end thereof adjacent to the driving member 13, through which the cleaning liquid is introduced into the outer tube 11. The push-away piece 14 can be made of metal material, such as stainless steel, and can be cleaned or sterilized at high temperature, so that the utilization rate of the push-away device 1 is improved.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, various possible combinations will not be separately described in this disclosure.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
