Furthermore, any single feature described or implicit in an embodiment herein or any single feature shown or implicit in the drawings or shown or implicit in the drawings may still allow any combination or permutation to continue between the features (or their equivalents) without any technical impediment, and thus further embodiments according to the present invention should be considered within the scope of this disclosure. In addition, for simplicity of the drawings, identical or similar parts and features may be indicated in the same drawing only in one or several places.

First, the basic configuration of an embodiment of a subcutaneous space creation device for surgery according to the present invention is generally illustrated in fig. 1 and 2 in a schematic manner. In this embodiment, the subcutaneous space creation apparatus 100 may include a body 10 and a combined platform 12, and the present invention will be described in detail by this example.

Referring to fig. 1 and 2 in combination, in the subcutaneous space creation device 100, the body 10 may be made of any suitable material, such as a flexible material, so that it can be folded for delivering at least a portion thereof to the skin during surgery or expanded for creating a subcutaneous space for surgery.

In particular, the body 10 may be provided with an inflatable chamber 11 and may constitute the whole or a part of the body 10, for example, in the embodiment shown in fig. 1, the tapered conical part of the body 10 is the inflatable chamber 11, and the inflatable chamber 11 is connected to other components 11' which are connected to the inflatable chamber 11 and constitute the body 10. In alternative cases, the inflatable chamber 11 may be formed by an inner and an outer layer or more layers to form the inflatable space, while the portion 11' may be formed by a single layer directly and may be configured in any suitable shape according to different application requirements. Of course, the present invention also allows to eliminate the above-mentioned portion 11', and to form the body 10 as a whole by the inflatable chamber 11, for example, the whole body 10 can be directly formed by the inflatable chamber 11 having a cone shape in fig. 1. Further, as an alternative, the height of the inflatable chamber 11 may be set to be in the range of 2-30cm or any other suitable range.

When not inflated, the inflatable chamber 11 is in a contracted configuration, in which the body 10 is collapsed to a small volume, thereby occupying a limited space for delivery subcutaneously through a surgical incision. When the inflatable chamber 11 is inflated, it will expand and form an expanded configuration, in which the body 10 will form a first port 101, a second port 102 and a hollow channel 103. When the inflatable chamber 11 has been brought into an expanded configuration and is ready for surgery, the first port 101 and the second port 102 will be distributed subcutaneously and outside the surgical incision, and the hollow channel 103 communicating with the above two ports will support the surgical incision, thereby creating a space providing the desired surgical operation for many types of medical instruments or tools, such as endoscopes, laparoscopes, graspers, snares, separation scissors, electrocoagulation hooks, airway tubes, etc., to perform the corresponding operations via the hollow channel 103.

In the subcutaneous space creation device 100, the body 10 may be configured such that at least a part of the cross section of the above-described first port 101 has a circular arc shape, and/or at least a part of the cross section of the above-described second port 102 has a circular arc shape. By adopting the above structural designs, it is particularly advantageous when performing surgical operations (e.g., minimally invasive kidney surgery, minimally invasive hepatobiliary surgery, thyroidectomy, prostatectomy, etc.) on some organs.

For example, as shown in fig. 1 and 2, the first port 101 and the second port 102 may be configured such that their respective cross-sections are circular or elliptical, and also such that the cross-sectional area of the former is not greater than that of the latter. Furthermore, an overall smooth transition may be formed from the first port 101 to the second port 102, for example, such that the inflatable chamber 11, which is now part of the body 10, forms a hollow conical shape (or may be other shapes such as a cylindrical shape) in the expanded configuration, which is exemplarily shown in fig. 1 and 2. Thus, when for example, a minimally invasive surgery is used to perform a surgical operation on a plurality of organs such as kidney and thyroid, the subcutaneous space creating device according to the present invention can be used very conveniently and efficiently to create a stable and reliable surgical space, and can safely and reliably protect internal organs and tissues during the operation, and also avoid the adverse effect on patients due to the use of gas such as carbon dioxide in the operation, thereby facilitating the safe, reliable and efficient implementation of these surgical operations.

Further, in an alternative case, the body 10 may be provided with a hydrophilic layer on a part of or the entire outer surface thereof in order to reduce resistance when passing through a surgical incision into the subcutaneous space. For example, the entire outer face of the inflatable chamber 11 described above may be provided with a hydrophilic layer. In practical applications, such a hydrophilic layer may be one of polyvinylpyrrolidone, polyethylene oxide, polyethylene glycol, polypropylene glycol, polyacrylamide, polyacrylic acid, or a composite thereof.

With continued reference to fig. 1 and 2, the composite platform 12 is provided as an optional part that may be removably mounted to the body 10. In actual use, the combining platform 12 may be configured in any suitable shape for combined assembly with the second port 102 of the body 10. Depending on the requirements of a specific application, one, two or more channel nozzles 13 may be disposed on the combination platform 12 so as to selectively feed various medical instruments or tools, such as endoscopes, electronic laparoscopes, snares, electrocoagulation hooks, ventilation tubes 14, exhaust tubes 15, placeholder replacement rods 40, etc., into or through the hollow channel 103 via the channel nozzles 13 to reach their respective target locations, which is beneficial for preventing interference with the performance of the operation due to interference between the medical instruments or tools, etc., during the operation. It should also be understood that the present invention is not intended to be limited to the actual shape and size, number of arrangements, placement, materials used, etc. of the passage orifices 13, which all allow for flexible settings according to different application requirements.

It should be noted that in some embodiments, by selecting suitable materials, structural optimization, etc., the body 10 may have sufficient mechanical properties such as strength, rigidity, etc. when the inflatable cavity 11 is in the expanded configuration, thereby ensuring that the subcutaneous space created is sufficient to meet the surgical requirements. As an alternative, the present invention allows to provide one, two or more reinforcing supports 18 on the inner and/or outer wall of the inflatable chamber 11, in order to act as structural reinforcement or the like for the body 10 in the expanded configuration. In a specific application, the reinforcing support 18 may be disposed around the circumference of the inflatable cavity 11, along the axial direction of the inflatable cavity 11, or a combination thereof. In addition, the structural shape, size, etc. of the reinforcing support 18 itself are also allowed to be flexibly set according to actual needs.

Furthermore, in alternative cases, it is contemplated that one, two or more attachment portions 19 may be provided on the inner and/or outer walls of the inflatable cavity 11 to provide attachment functions for some surgical instruments, such as endoscopes, electro-laparoscopes, ventilation tubes 14, exhaust tubes 15, placeholder rods 40, etc., depending on the requirements of the application. This is exemplarily illustrated in fig. 2, and it is understood that the specific configuration, size, number of arrangement, arrangement position, etc. of such attachment portion 19 can be flexibly designed and adjusted according to the actual application requirement.

In the embodiments discussed above, the subcutaneous space creation device 100 may also be configured with one or more vent tubes 14, one or more vent tubes 15, and one or more control valves 16. The vent tube 14 has one end connected to the corresponding opening 110 of the inflatable chamber 11 and the other end extending to the outside of the body 10 for connecting to a member, device or apparatus (such as a manually or electrically operated pump, inflation needle, etc.) for inflating and deflating the inflatable chamber 11. The exhaust tube 15 may be disposed at one end thereof on the body 10 (e.g., disposed within the inflatable chamber 11 and extending to or near the first port 101) and at the other end thereof extending to the exterior of the body 10, so as to be connected to any suitable component, device or apparatus, such as a suction pump, for sucking smoke and/or gases from the patient's skin (e.g., generated by the operation of a medical instrument, such as an electrocoagulation hook, during a surgical procedure) and exhausting the smoke and gases to the exterior of the body, so as to improve the visibility of the surgical procedure and substantially ensure the safety of the surgical procedure.

Alternatively, in order to better control the above-mentioned inflation/deflation operation or the ventilation operation, the ventilation tube 14 and/or the ventilation tube 15 may be provided with a control valve 16 (such as a one-way valve, a three-way valve, etc.), for example, such a control valve 16 may be detachably mounted on the respective ends of the ventilation tube 14 and the ventilation tube 15 outside the body 10 to facilitate the control operation, for example, the control valve 16 may be manipulated to release the gas filled in the inflatable cavity 11 after the operation is completed, so as to recover or substantially recover the gas to the previous contracted configuration and then withdraw the gas from the body.

Furthermore, in an alternative case, the subcutaneous space creation device may also be directly provided with an inflation operation member 17 (such as a manually operable inflation bladder or the like as shown in FIG. 3) for communicating with the vent tube 14 for a very convenient and efficient on-site inflation operation of the inflatable chamber 11.

In addition, a placeholder replacement bar 40 is schematically illustrated in fig. 2, which is attached inside the inflatable cavity 11 in the contracted configuration for performing a pre-space occupation, so that when a surgical operation is to be performed, a corresponding surgical instrument (such as an endoscope, an electronic laparoscope, etc.) can be very easily inserted to replace it and accurately reach a desired site, thereby effectively saving time and improving efficiency, and avoiding the possible risk of surgical safety due to improper placement of the surgical instrument, time consumption, etc.
