Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a laparoscopic surgical perforator. Background Art

[0002] The placement and removal of the incision protection cover are very important steps in the surgical process, which are directly related to the protection of the surgical incision and the surgical effect. Figure 1 As shown, the incision protection sleeve includes a membrane channel 100, an outer ring 101, and an insertion ring 102 connected to both ends of the membrane channel 100. The outer ring 101 and the insertion ring 102 have elastic deformation and rebound properties. Currently, when inserting the incision protection sleeve into the patient's body, medical staff usually manually flatten the hard elastic ring and then insert it into the patient along the surgical incision while pinching it. This method usually requires a larger surgical incision and is prone to squeezing the patient's surgical incision during the insertion process, causing increased pain for the patient. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the existing technology, the purpose of the present invention is to provide a laparoscopic surgical perforator, which solves the technical problems that the existing incision protection cover will squeeze the surgical incision during insertion, increasing pain for the patient, and the incision protection cover is inconvenient to operate.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A laparoscopic surgery perforator inserter comprises: a sleeve having a channel; a through incision formed on the side wall of the sleeve along its length, and the incision is connected to all the channels; a protective plate arranged at one end of the sleeve, and the incision extends to the protective plate.

[0006] The incision protection cover of the present invention utilizes a cannula during insertion, thereby reducing the size of the surgical incision on the patient. Furthermore, the incision protection cover does not squeeze the surgical incision during insertion, thereby minimizing pain for the patient. Furthermore, by providing an incision in the sidewall of the cannula, the incision protection cover can be inserted more easily, improving insertion efficiency. When the incision protection cover needs to be removed, the surgical incision can be removed with minimal squeezing, facilitating separation of the incision protection cover from the access port.

The trumpet-shaped ring body and protective disc facilitate the insertion of the ring and the pushing component into the sleeve channel, making operation more convenient and rapid.

[0009] Optionally, the inner side of the protective plate is chamfered.

[0010] Optionally, the left and right ends of the sleeve are in arc or semicircular structures, the front and rear sides of the sleeve are in straight structures, and the incision is provided on the straight section of one side.

[0011] Optionally, the left and right ends of the protective plate have arc-shaped portions, the front and rear sides of the protective plate have straight portions, and the cutout extends to one of the straight portions.

[0012] Optionally, the perforator further includes a pushing component, which is movably disposed in the channel and is used to push the incision protection sleeve to move along the channel.

[0013] Optionally, the pushing component includes: a rod; a push plate disposed at one end of the rod; and a limit plate disposed at the other end of the rod; wherein the push plate is adapted to fit within the channel and moves along the channel under the action of a thrust force. The cooperation between the pushing component and the sleeve further facilitates the insertion of the incision protection sleeve.

[0014] Optionally, one end of the ring body gradually increases in diameter from the outer wall of the sleeve toward the top, and the lower end of the ring body and the top of the sleeve form a step, and the bottom of the limiting plate can rest on the step.

[0015] Optionally, the height H of the limiting plate is greater than the height h of the ring body and the protective plate.

[0016] Optionally, a slider is provided on the outer wall of one side of the push plate, and the slider is adapted to the incision. When the push plate is placed in the channel, the incision becomes a movement channel for the slider.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The incision protection sleeve of this invention utilizes a cannula for insertion, thereby minimizing the surgical incision on the patient. Furthermore, the incision protection sleeve does not squeeze the surgical incision during insertion, thereby minimizing pain for the patient. Furthermore, the incisions created in the sidewalls of the cannula facilitate insertion of the incision protection sleeve, improving insertion efficiency.

[0035] The disclosure below provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figures 2 to 6 As shown, the embodiment of the present invention provides a laparoscopic surgical perforator, primarily used for single-port laparoscopic surgery. The perforator comprises a cannula 1 having a hollow elliptical channel 11 formed therein. The cannula 1 is provided with a cutout 12 along its length, the cutout 12 being connected to the channel 11. A protective plate 2 is provided at the top end of the cannula 1. The inner side of the protective plate 2 forms a portion of the channel 11, and the cutout 12 extends onto the protective plate 2.

[0039] The sleeve 1 is a hollow elliptical structure, that is, the front and rear sides of the sleeve 1 are straight structures, the cutout 12 is provided on the straight section of one side, and the left and right ends of the sleeve 1 are arc-shaped or semicircular structures.

[0040] When the incision protection cover needs to be inserted into the surgical incision and / or removed from the surgical incision, the incision protection cover is flattened into a narrow oval shape and sent into the incision or removed from the incision through the channel 11. By opening the incision 12 on the side wall of the sleeve 1, the insertion operation of the incision protection cover and the separation of the incision protection cover from the channel 11 can be facilitated.

[0041] As an implementation scenario, in this scenario, when the incision protection cover needs to be placed in the surgical incision, the ring of the incision protection cover is flattened into a narrow oval shape and placed in the channel 11, and then the incision protection cover is pushed out of the cannula 1 by the pushing component. During operation, the incision protection cover can be inserted into the cannula 1 first, and then one end of the cannula 1 is inserted into the patient's body along the surgical incision, and finally the incision protection cover is pushed out of the cannula 1 by the pushing component.

[0042] As another implementation scenario, in this scenario, during operation, the puncture component can be inserted into the channel 11 of the sleeve 1, and then the puncture component pierces the patient's abdomen to make an incision. The puncture component can smoothly pass through the sleeve and pierce the abdominal wall using the puncture component. Then the puncture component is pulled out, leaving the puncture sleeve in the abdominal cavity, and then the incision protection sleeve is inserted into the sleeve 1 from one end of the sleeve 1. Finally, the incision protection sleeve is pushed out of the sleeve 1 by the pushing component. Through the channel formed by the puncture sleeve 1 and the incision protection sleeve, the doctor can insert various surgical instruments to perform surgical operations.

[0043] The incision protection sleeve of the present invention utilizes a cannula for insertion, thereby reducing the surgical incision on the patient. Furthermore, the incision protection sleeve does not squeeze the surgical incision during insertion, thereby minimizing pain for the patient. Furthermore, by providing an incision 12 on the sidewall of the cannula 1, the insertion ring of the incision protection sleeve can be placed within the channel 11 during insertion. The membrane channel then passes through the incision 12, allowing the outer ring to be inserted into the channel 11. The incision 12 facilitates insertion of the incision protection sleeve, improving insertion efficiency.

[0044] In other embodiments, when removing the incision protection cover, the doctor will select an appropriate tool (such as pliers), enter through the channel 11, gently grasp a part of the incision protection cover (such as the inner side of the outer ring), and then slowly pull it outward. During this process, the membrane channel and the incision wall gradually loosen and separate. As the membrane channel and the incision wall gradually separate, the medical staff will continue to pull outward. The membrane channel passes through the incision 12. At this time, the insertion ring can also be placed in the channel 11. The medical staff will continue to pull outward until it is completely removed from the incision. In this way, the incision protection cover will not squeeze the surgical incision as much as possible when it is removed, and the removal operation can be facilitated.

[0045] Example 2

[0046] Based on Example 1, the left and right ends of the protective plate 2 have arc-shaped portions 21, and the front and rear sides of the protective plate 2 have straight portions 22. The cutout 12 extends to one of the straight portions 22, that is, the straight portions of the protective plate 2 corresponding to the cutouts of the sleeve 1 are also provided with cutouts that are connected to the cutouts of the sleeve 1.

[0047] As an implementation scenario, in this scenario, for example, reference Figure 7As shown, the puncture component includes a puncture rod 41 and a top cover 42 provided on one end of the puncture rod 41 away from the tip of the puncture rod 41. When in use, the medical staff first inserts the puncture rod 41 into the channel 11, then inserts the puncture rod 41 into the patient's abdomen to make an incision, and can simultaneously insert the cannula 1 into the incision so that the cannula 1 enters the patient's abdomen, and then inserts the incision protection cover into the cannula 1 from one end of the cannula 1, and finally pushes the incision protection cover out of the cannula 1 through the pushing component. In this embodiment, through the provision of the straight portion 22, when the puncture component passes through the channel 11, there is a certain gap between the outer side of the straight portion 22 and the bottom of the top cover of the puncture component, which makes it convenient to hold the top cover to take and place the puncture component, and also improves the smoothness of the edge of the protective plate 2, making it easier to operate.

[0048] Example 3

[0049] In addition to Example 1 or Example 2, an annular body 3 is disposed between the sleeve 1 and the protective disc 2. The annular body 3 extends outward from one end of the sleeve 1 in a trumpet-shaped structure. The protective disc 2 is molded outside the annular body 3, i.e., the protective disc 2 is molded radially outward from the annular body 3. The notch 12 extends through the annular body 3 and the protective disc 2, i.e., the notch 12 extends toward the annular body 3 and the protective disc 2 to form a continuous notch.

[0050] Optionally, the inner side of the protective plate 2 is chamfered.

[0051] Optionally, the sleeve 1, the ring body 3 and the protective disk 2 are integrally formed.

[0052] In this embodiment, the trumpet-shaped ring body 3 and the protective plate 2 are provided, so that the ring and the pushing component can be easily placed into the channel of the sleeve, which is convenient for operation.

[0053] Example 4

[0054] The present invention provides a laparoscopic perforator inserter, Figure 8 and Figure 9 As shown, the perforator further includes a pushing component 5 , which is movably disposed in the channel 11 and is used to push the incision protection cover to move along the channel 11 .

[0055] The pushing component 5 includes a rod body 51 and a pushing plate 52 and a limiting plate 53 respectively provided at two ends of the rod body.

[0056] The push plate 52 is adapted to fit within the channel 11 and can slide freely within it. Preferably, the push plate 52 is slightly smaller than the channel 11, which facilitates better stability when the push plate 52 pushes the incision protection sleeve. The outer diameter of the limiting plate 53 is larger than the inner diameter of the channel 11, and the height H of the limiting plate 53 is greater than the height h of the ring body 3 and the protective plate 2.

[0057] Optionally, the rod body 51 may also adopt the same structure as the push plate 52 .

[0058] Optionally, one end of the ring body 3 gradually increases in diameter from the outer tube wall of the sleeve 1 toward the top, and the lower end of the ring body 3 and the top of the sleeve 1 form a step 13. The limit plate 53 is adapted to the step 13, and the limit plate 53 can rest on the step 13, that is: the structure of the limit plate 53 is the same as the cross-section of the sleeve 1, and its front and rear sides are flat structures, and the left and right ends are arc-shaped or semicircular structures.

[0059] Optionally, a slider 54 is provided on the outer wall of one side of the push plate 52. The slider 54 fits within the notch 12. When the push plate 52 is placed within the channel 11, the slider 54 fits within the notch 12, thereby forming a movement channel for the slider 54. Specifically, the push plate 52 has arc-shaped or semicircular structures on its left and right ends and flat structures on its front and back ends, with the slider 54 disposed on the sidewall of one of the flat structures. During use, when the push plate 52 is in motion, the slider 54 moves along the notch 12, making the movement of the rod body 51 within the sleeve 1 more stable.

[0060] As an implementation scenario, in this scenario, when inserting, the insertion ring of the incision protection sleeve can be placed in the channel 11 first. At this time, the membrane channel will pass through the incision 12, and then continue to insert the outer ring into the channel 11. When the incision protection sleeve is completely inserted into the channel 11, the push plate 52 is inserted from the push plate 52 into the channel 11, and then the limit plate 53 is pushed until the incision protection sleeve is pushed to the specified position.

[0061] In other embodiments, the sleeve can also be used in conjunction with an operating platform, such as connecting the sleeve to a multi-channel operating platform.

[0062] When in use, the insertion ring and the outer ring of the incision protection sleeve can have the same diameter, that is, the diameter of the insertion ring is larger than the diameter of the outer ring.

[0063] Parts not described in detail in this embodiment are well-known technologies in the art.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention.
