Referring to fig. 1, a schematic overall structure of a multifunctional surgical needle set according to the present embodiment is shown.
The tube sheath 1 of the multifunctional surgical needle group is used as a basic structure, and a puncture needle 2, a cryoablation needle 3, a thermal ablation needle 4, an irreversible electroporation needle 5 and an injection needle 6 are selected to perform corresponding surgical treatment in a minimally invasive surgical process according to clinical use requirements. Specifically, surgical needles with different functions can be sequentially selected to pass through the sheath 1 and be inserted into the treatment part to implement different treatment operations, so that the aim of completing a composite treatment scheme by one operation is fulfilled.
For better adapting to the environmental requirements of surgical needles with different functions, the sheath 1 can be further optimized, please refer to fig. 2, which is a schematic structural view of the sheath shown in fig. 1.
As shown in the figure, the sheath 1 includes a vacuum base housing 11 and a double-layer tube 12 in communication with vacuum. The insertion opening 131 for each surgical needle is located at the upper end of the vacuum base cover 11, and each surgical needle is inserted from the vacuum base cover 11 when in use. Wherein, a vacuum interlayer is formed between the inner tube sheath 121 and the outer tube sheath 122 of the double-layer tube body 12, the upper end of the inner tube sheath 121 is inserted into the vacuum matrix cover 11 and is communicated with the insertion opening 131 of the surgical needle, and the upper end of the outer tube sheath 122 is communicated with the vacuum matrix cover 11; and the inner tube sheath 121 is sealed with the lower end of the outer tube sheath 122. Thereby, a vacuum space is established between the vacuum base cover 11 and the double-layer tube 12. The vacuum base cover 11 provides a vacuum structure setting position, and can be used as a holding operation part in operation, so that the medical staff can conveniently perform operation.
Wherein, the penetration of the inner tube sheath 121 and the insertion opening 131 of the surgical needle means that the inner tube sheath 121 and the insertion opening 131 of the surgical needle are communicated with the outside in a sealing way, the surgical needle holder 13 inserted in the vacuum matrix cover 11 is preferably adopted in the scheme, the surgical needle holder 13 is connected with the upper end of the inner tube sheath 121 in a sealing way, the insertion opening 131 of the surgical needle is positioned at the upper end of the surgical needle holder 13, the inner cavity of the surgical needle holder 13 is provided with a surgical needle limiting step 132, and the needle body of each surgical needle is provided with an outer convex large-diameter section matched with the limiting step 132 so as to limit the working position of the surgical needle relative to the longest extension length of the tube sheath 1.
The lower end sealing of the inner tube sheath 121 and the outer tube sheath 122 may be achieved by different processes, for example, welding the ends of the two or integrally forming the two. The lower ends of the inner tube sheath body 121 and the outer tube sheath body 122 are sealed by adopting the connecting tube head 123, as shown in the figure, the inner wall surface and the outer wall surface of the connecting end of the connecting tube head 123 are respectively provided with an adapting step, the inner tube sheath body 121 and the outer tube sheath body 122 are attached to corresponding steps and welded to form a tube sheath end with better rigidity, and the inner surface and the outer surface are smoothly transited after welding; in addition, the lower end of the connector 123 has a guiding chamfer for easy intraoperative manipulation.
Further, a vacuum nozzle 14 for drawing vacuum, which communicates with the vacuum interlayer, may be provided on the vacuum base cover 11 for establishing vacuum insulation of the sheath. As shown, the vacuum nozzle 14 is preferably a deformable metal tube, such as an oxygen-free copper tube. And then cold pressure welding sealing is carried out after air extraction is completed, so that a complete sealing space is formed. Of course, the vacuum nozzle 14 of the needle assembly 1 can also be sealed by a vacuum plug after vacuumizing, so that a vacuum state can be formed in a cavity between the outer wall of the surgical needle seat 13 and the inner wall of the vacuum matrix cover 11, and the vacuum cavity is communicated with a vacuum interlayer formed between the inner tube sheath 121 and the outer tube sheath 122 of the double-layer tube body 12, so as to achieve the purposes of heat insulation or cold insulation.
In addition, a getter accommodating chamber 111 is provided at the lower end of the vacuum base cover 11, in which a getter is provided for absorbing gas in the heat-insulating vacuum interlayer of the double-layered pipe body 12, thereby allowing the vacuum degree of the vacuum interlayer to be maintained for a long time. As shown in the figure, the inner tube sheath 121 is inserted out of the getter housing 111, and then is connected to the surgical needle holder 13 in a sealed manner, and further penetrates the surgical needle insertion port 131. In this embodiment, the getter is an evaporable getter, a non-evaporable getter or a compound getter, and a commercially available product can be selected as needed.
Further, the heat insulation layer of the double-layer tube body 12 in the scheme is used for isolating the cold energy or heat of the cryoablation needle 3 or the thermal ablation needle 4 and preventing the cryoablation needle 3 or the thermal ablation needle 4 from frostbite or scalding normal tissues of the puncture path; the needle tip part of the cryoablation needle 3 or the thermal ablation needle 4 is exposed out of the sheath, the precise targeted cryoablation operation or the thermal ablation operation is carried out on the treatment part, and the shape and the range of the treatment area can be controlled by adjusting the length of the needle tip part of the cryoablation needle 3 or the thermal ablation needle 4 exposed out of the sheath 1. Meanwhile, the double-layered tube body 12 further includes an electromagnetic field shielding layer (not shown) for shielding the electric field or electromagnetic field of the thermal ablation needle 4 and the electric field of the irreversible electroporation needle 6, so that the shape and extent of the treatment area can be controlled by controlling the length of the thermal ablation needle 4 or the needle tip portion of the irreversible electroporation needle 5 exposed out of the sheath 1.
Referring to fig. 3, a schematic view of the lancet shown in fig. 1 is shown.
The puncture needle 2 is used for minimally invasive surgery and functions to puncture tissue to open a path for minimally invasive surgery so that the sheath 1 reaches the surgical treatment site. In operation, the puncture needle 2 is matched to enable the tube sheath 1 to reach the operation treatment position, and then the puncture needle 2 is pulled out from the tube sheath 1, so that a channel leading to the treatment position can be formed. It should be appreciated that the puncture needle 2 is generally lightweight and flexible, and is used in combination with a CT scanning device, and is more easily operated in the sheath 1, so as to be inserted into focal tissue efficiently and quickly; in contrast, other needles such as the cryoablation needle 3 or the thermal ablation needle 4 have relatively heavy needle bodies, are easily inclined in the sheath 1, and are not convenient to manually operate until reaching the focus part once without assistance.
As shown, the upper part of the needle body of the puncture needle 2 has a convex large diameter section 21 for adapting to the limit step 132 of the surgical needle holder 13 of the sheath 1, the end face of which large diameter section can be abutted against the limit step 132 of the surgical needle holder 13 so as to define the relative working position of the puncture needle 2 with respect to the longest extension of the sheath 1.
Referring to fig. 4, a schematic view of the cryoablation needle of fig. 1 is shown.

As a preferred scheme, the needle tube of the cryoablation needle 3 can be provided with no heat insulation layer, a refrigerant working cycle is established, and the needle tube is matched with the tube sheath 1 with the double-layer tube 12 vacuum interlayer for use (when in use, the part of the cryoablation needle 3, which extends out of the tube sheath 1 at the needle tip, is a treatment section contacted with tumor tissues), so that the normal tissues of the puncture path can be prevented from being frostbitten by the cryoablation needle 3. During operation, the cryoablation needle 3 can enter the treatment part through the path opened by the puncture needle 2, or the combination of the cryoablation needle 3 and the tube sheath 1 can be punctured into the treatment part, and the accurate targeted cryoablation operation is implemented on focal tissues.
In addition, the outer periphery of the holding section 31 above the cryoablation needle 3 is provided with a heat insulation layer 311 so as to facilitate the holding operation of medical staff. As shown, the outer diameter of the hand-held section 31 is greater than the outer diameter of the needle body 32, and the end surface of the large diameter section can abut against the limit step 132 of the surgical needle holder 13 of the sheath 1 to define the relative working position of the cryoablation needle 3 relative to the longest extension of the sheath 1.
Referring to fig. 5, a schematic view of the thermal ablation needle of fig. 1 is shown.
The thermal ablation needle 4 is used for minimally invasive thermal ablation surgery, and as in the prior art, uses the thermogenic biological effect to directly cause irreversible damage or coagulative necrosis of tumor cells in focal tissues. The thermal ablation needle 4 comprises a microwave thermal ablation needle and a radio frequency thermal ablation needle. As a preferable scheme, the needle tube of the thermal ablation needle 4 can be provided with no heat insulation layer, and only has the function of realizing thermal ablation, and is matched with the tube sheath 1 with the double-layer tube body 12 (the interlayer of the double-layer tube body 12 is an electromagnetic field shielding layer at the moment), and when the needle tube is used, the part of the thermal ablation needle 4, which extends out of the tube sheath 1 at the needle tip, is a treatment section which contacts tumor tissues. During operation, the thermal ablation needle 4 enters the treatment part through the path opened by the puncture needle 2, or the combination of the thermal ablation needle 4 and the tube sheath 1 is punctured into the treatment part, and the precise targeted thermal ablation operation is implemented on focal tissues.
As shown, the outer diameter of the hand-held section 41 is greater than the outer diameter of the needle body 42, and the end surface of the large diameter section can abut against the stop step 132 of the surgical needle hub 13 of the sheath 1 to define the relative working position of the thermal ablation needle 4 relative to the longest extension of the sheath 1.
Referring to FIG. 6, a schematic diagram of the structure of the irreversible electroporation needle shown in FIG. 1 is shown.
The irreversible electroporation needle 5 is used for minimally invasive surgery, and as in the prior art, is percutaneously pierced into focal tissue using an electrode needle. By means of ultrashort electric pulse, powerful electric field is generated to kill tissue cells. In operation, the irreversible electroporation needle 5 enters the treatment part through the open path of the puncture needle 2, or the irreversible electroporation needle 5 and the tube sheath 1 are combined and then puncture into the treatment part, so that accurate targeted operation is performed on focal tissues.

The injection needle 6 is used for minimally invasive surgery, and is used for entering a treatment part, and during surgery, the injection needle 6 can enter the treatment part through a path opened by the puncture needle 2, or the injection needle 6 and the tube sheath 1 can be combined and then puncture into the treatment part, so that medicament is injected into focus tissues for treatment. Treatment is performed by injecting a medicament into the focal tissue.
Preferably, the upper part of the needle body of the injection needle 6 has a convex large diameter section 61 for adapting to the limit step 132 of the surgical needle holder 13 of the sheath 1, the end face of which large diameter section can abut against the limit step 132 of the surgical needle holder 13 as shown in the figure, so as to define the relative working position of the injection needle 6 with respect to the longest extension of the sheath 1. In addition, the needle wall of the needle tip of the injection needle 6 has a plurality of openings therein, which facilitates the adequate contact of the therapeutic liquid with the focal tissue during injection.
It should be noted that the functional principle of each surgical needle in the needle set in this embodiment is the same as that of the prior art, so that other functional structures are not described herein. The materials of the sheath 1, the puncture needle 2, the cryoablation needle 3, the thermal ablation needle 4, the irreversible electroporation needle 5 and the injection needle 6 can be metal, inorganic nonmetallic materials, high polymer materials and combinations thereof.
The device for minimally invasive composite treatment and the multifunctional surgical needle group thereof provided by the invention can be matched with the sheath by utilizing a plurality of surgical needles, and can be combined according to a clinical composite treatment scheme, such as a puncture needle, a cryoablation needle, a thermal ablation needle, an irreversible electroporation needle or an injection needle, so that in the process of minimally invasive surgery, surgical needles with different functions can be sequentially selected to pass through the sheath and be inserted into a treatment part to implement different minimally invasive surgeries, the purpose of disposable composite treatment is achieved, and the treatment effect is improved. Compared with the prior art, on the premise of not increasing the operation wounds, different minimally invasive treatment methods can be used in the same minimally invasive operation, a plurality of operation wounds are not generated for a patient who makes a composite treatment scheme, on the basis of effectively reducing the operation pain of the patient, the repeated cost of a plurality of operation rooms can be reduced, and the treatment period is greatly shortened; in addition, because during treatment, a doctor can control the length of the needle tip extending out of the sheath end, the length of the needle tip extending out of the sheath end can be flexibly adjusted according to the shape of focus tissues, and the shape and the range of a treatment area can be controlled. For example, if the focal tissue is approximately elongate, the tip of the needle can be controlled to extend further out of the sheath end; so that the treatment is more sufficient.
In addition to the foregoing multi-functional surgical needle set, the present embodiment also provides an apparatus (not shown in the figures) for minimally invasive compound treatment, including the multi-functional surgical needle set as described above, and a functional module interface therapeutic apparatus having correspondence with the corresponding treatment in the surgical needle set.
