Description

Technical Field

[0001] The invention relates to the medical field, and in particular to a laparoscopic minimally invasive port protection slide. Background Art

[0002] When using a laparoscope, it is often necessary to establish a protective slide as a channel at the wound site. Traditional sliding sleeves are placed in place after direct puncture and passed through the laparoscope inside for operation. However, when using this method, it is often necessary to inject protective gas into the abdominal cavity to inflate the abdomen and bulge it, so as to establish a relatively open surgical space and operating field of view. However, the puncture needle used in this method is very likely to have a pressure difference from the inside to the outside due to the injection of gas into the abdomen after being placed in place. Combined with the continuous movement of the needle during the operation, the puncture needle retention sleeve is very likely to shift, or a small amount of body fluid exudates, which needs to be cleaned, affecting the progress of the operation. Summary of the invention

[0003] The purpose of the present invention is to solve the problem of potential safety hazards in the traditional puncture needle retention, and to propose a laparoscopic minimally invasive port protection slide.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a laparoscopic minimally invasive port protection slide, comprising a puncture sleeve and a puncture needle axially penetrating therein, and a sealing assembly that cooperates and seals between the puncture sleeve and the puncture needle, and also comprising a protection boss arranged on the surface of the puncture sleeve;

[0005] The puncture cannula includes a pressurized chamber and an integrally formed puncture tube body, the puncture needle includes an integrally formed head and needle body, and the needle body penetrates and slides in the pressurized chamber and the puncture tube body, the sealing assembly includes a sealing disk and an adapter seat respectively attached to the opposite sides of the head and the pressurized chamber, and the inner walls of the adapter seat and the sealing disk jointly press the positioning ring, the pressure ring and the sealing rubber;

[0006] The protective boss comprises a clamp for fitting to the surface of the puncture tube body and locking it, a retaining disk is fixed on one side of the clamp, and a film is fitted on the surface of the retaining disk.

[0007] As a further description of the above technical solution: the fixture includes a left half ear and a right half ear symmetrically arranged on both sides of the puncture tube body, one end of the left half ear and the right half ear are movably connected, the other end of the left half ear is fixed with a sliding nail, the sliding nail slides through the other end of the right half ear, the inner wall of the right half ear is movably connected with a seesaw through a pin shaft, one end of the seesaw is fixed with a top block for squeezing the sliding nail, and a pressing sleeve is jointly arranged in the left half ear and the right half ear.

[0008] As a further description of the above technical solution: two films are attached to the exposed part of the film beyond the retaining plate, and the retaining plate is fixed on one side of the left half ear.

[0009] As a further description of the above technical solution: the puncture sleeve also includes a sealing pressure ring arranged in the pressurized chamber, the adapter seat is threadedly fitted on one side of the pressurized chamber and tightly fits the inner wall of the sealing pressure ring, and one side of the positioning ring penetrates and fits on the inner wall of the adapter seat.

[0010] As a further description of the above technical solution: the sealing disk is threadedly engaged with one side of the adapter, and the sealing disk is pressed against the surface of the sealing rubber, and the sealing rubber and the positioning ring are pressed toward each other to deform in a ring shape.

[0011] As a further description of the above technical solution: the sealing rubber is arranged in a cone shape with openings at both ends.

[0012] As a further description of the above technical solution: the puncture cannula also includes a valve connected to the pressurizing chamber, and two finger pressure platforms are symmetrically arranged on the surface of the pressurizing chamber.

[0013] As a further description of the above technical solution: a scraping groove for scraping off dirt is provided at the junction of the puncture tube body and the pressurizing chamber, and an annular texture is provided on the surface of the puncture tube body.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] In this solution, the puncture needle is directly pulled out after puncture, and the puncture cannula is kept in the wound. Then the laparoscope is inserted and passed through the sealing component. At this time, the connection can be maintained by opening the valve. After air is injected, the laparoscope can continue to go deeper. In this way, the interior can be relatively sealed and the gas injected into the abdominal cavity can be prevented from flowing back out, which is convenient for operation.

[0016] At the same time, this solution uses the design of a protective boss to cover the wound around the retaining plate and attach the film to the skin. Since the retaining plate film cannot be attached to the area close to the wound, and a positioning function is provided for the retaining plate, when the puncture cannula moves to an appropriate depth, it can be locked by a clamp, and the subsequent removal of the puncture needle, replacement of the laparoscope, and even the introduction of protective gas can ensure the positioning of the puncture tube body to prevent displacement. In addition, this method can seal the wound to prevent leakage of body fluids from affecting the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1 - Fig. 9 As shown, the present invention provides: a laparoscopic minimally invasive port protection slide, comprising a puncture sleeve 1 and a puncture needle 3 axially penetrating therein, and a sealing assembly 2 that cooperates and seals between the puncture sleeve 1 and the puncture needle 3, and also comprises a protection boss 4 disposed on the surface of the puncture sleeve 1;

[0033] The puncture cannula 1 includes a pressurized chamber 11 and an integrally formed puncture tube body 12, the puncture needle 3 includes an integrally formed head 31 and a needle body 32, and the needle body 32 penetrates and slides in the pressurized chamber 11 and the puncture tube body 12, the sealing assembly 2 includes a sealing disk 22 and an adapter 21 respectively attached to the opposite sides of the head 31 and the pressurized chamber 11, and the inner walls of the adapter 21 and the sealing disk 22 are jointly pressed to hold a positioning ring 23, a pressure ring 24 and a sealing rubber 25;

[0034] The protection boss 4 includes a clamp 41 for fitting and locking the surface of the puncture tube body 12 . A retaining plate 42 is fixed to one side of the clamp 41 . A film 43 is fitted on the surface of the retaining plate 42 .

[0035] Specifically, Figure 4 As shown: the fixture 41 includes a left half ear 411 and a right half ear 412 symmetrically arranged on both sides of the puncture tube body 12, one end of the left half ear 411 and the right half ear 412 are movably connected, the other end of the left half ear 411 is fixed with a slide nail 413, the slide nail 413 slides through the other end of the right half ear 412, the inner wall of the right half ear 412 is movably connected with a seesaw 414 through a pin shaft, one end of the seesaw 414 is fixed with a top block 415 for squeezing the slide nail 413, and a pressing sleeve 416 is jointly provided in the left half ear 411 and the right half ear 412.

[0036] When the clamp 41 is in use, the seesaw 414 can be rotated, and the seesaw 414 can be rotated through the small axis through the top block 415 to squeeze the sliding nail 413, so that the left half ear 411 and the right half ear 412 are close to each other and squeeze the pressing sleeve 416, so that the pressing sleeve 416 shrinks and fits on the annular texture on the surface of the puncture tube body 12 to achieve fixation.

[0037] Specifically, Figure 3 As shown, two films 44 are attached to the exposed portion of the film 43 beyond the retaining plate 42 , and the retaining plate 42 is fixed on one side of the left half ear 411 .

[0038] By providing the film 44, the sticking area of ​​the sticking film 43 can be protected and kept in a sterile state.

[0039] The retaining plate 42 is made of a soft rubber material, which can fit on the wound surface and can meet the requirements of downward pressure at different angles during the operation. At the same time, it protects the wound and prevents the wound from being pulled.

[0040] Specifically, Figure 6 As shown: the puncture sleeve 1 also includes a sealing pressure ring 14 arranged in the pressurized chamber 11, the adapter seat 21 is threadedly fitted on one side of the pressurized chamber 11 and tightly fits the inner wall of the sealing pressure ring 14, and one side of the positioning ring 23 penetrates and fits on the inner wall of the adapter seat 21.

[0041] When the adapter seat 21 is threadedly engaged in the pressurized chamber 11 , the adapter seat 21 can maintain the seal of the connection by fitting with the sealing pressure ring 14 , thereby achieving sealed connection and docking between the adapter seat 21 and the pressurized chamber 11 .

[0042] Specifically, Figure 5 and Figure 6 As shown, the sealing disk 22 is threadedly engaged with one side of the adapter 21, and the sealing disk 22 is pressed against the surface of the sealing rubber 25, and the sealing rubber 25 and the positioning ring 23 press the pressure ring 24 toward each other to deform.

[0043] The cooperation between the sub-disc and the adapter 21 enables the sealing rubber 25 and the positioning ring 23 to apply extrusion force from both sides under the threaded fixation between them, and maintain an elastic reaction force on the pressure ring 24 under the deformation to maintain the sealing performance.

[0044] Specifically, Figure 6 As shown: the sealing rubber 25 is arranged in a cone shape with openings at both ends.

[0045] The sealing rubber 25 is set in a cone shape so that gas can be passed into it. The sealing rubber 25 is consistent with the principle of the heart valve. The pressure of the internal gas keeps the sealing rubber 25 in a sealed state. The laparoscope from the outside punctures and enters, and it fits tightly to the surface of the laparoscope under pressure to maintain a sealed fit.

[0046] Specifically, Figure 8 As shown, the puncture cannula 1 further comprises a valve 13 connected to the pressurizing chamber 11 , and two finger pressure platforms 15 are symmetrically arranged on the surface of the pressurizing chamber 11 .

[0047] The setting of the finger pressure platform 15 can be conveniently held by the surgeon during the puncture operation, which is convenient for force application. At the same time, the valve 13 can facilitate the on-off control of the gas.

[0048] Specifically, Figure 7 As shown: a scraping groove 16 for scraping off dirt is provided at the junction of the puncture tube body 12 and the pressurizing chamber 11, and the surface of the puncture tube body 12 is provided with an annular texture.

[0049] By providing the scraping groove 16, when the puncture needle 3 is pulled out, the body fluid on its surface will be partially retained on the inner wall of the puncture cannula 1. At this time, if the laparoscope is inserted, it may re-enter the body with the laparoscope. By providing the scraping groove 16, the dirt on its surface can be scraped off and retained in the pressurized chamber 11;

[0050] At the same time, the annular texture can cooperate with the clamp 41 to lock, and will not shift after being locked, thereby improving the clamping tightness.

[0051] like Fig. 9 As shown, by locating the film 43 between the retaining disk 42 and the fixture 41, the retaining disk fixes the film 43, and the film 43 fixes the fixture 1, and the film 43 covers the inner wall of the puncture tube body 12, thereby achieving a higher sealing performance.

[0052] When the present solution is in use, the puncture needle 3 is inserted into the puncture sleeve 1, and the sealing head 31 is kept tightly fitted on one side of the sealing disk 22. At this time, the end of the needle body 32 is exposed to the puncture tube body 12. After puncture, the puncture angle is determined and the film 44 can be torn off, and the film 43 is attached to the wound. At this time, the film 43 keeps the disk 42 attached to one side of the wound. When the puncture tube body 12 reaches a suitable depth, the seesaw 414 is rotated so that the seesaw 414 squeezes the sliding nail 413 through the top block 415, so that the left half ear 411 and the right half ear 412 are clamped to each other under the action of the sliding nail 413, and the pressing sleeve 416 is pressed on the surface of the puncture tube body 12 to keep it fixed, and then the puncture needle 3 is pulled out, and the valve 13 is opened to inject gas. At this time, the sealing component 2 keeps the gas from being discharged, and the laparoscope is inserted. After the laparoscope passes through the sealing component 2, it is exposed from the end of the puncture tube body 12, completing the establishment of the protective boss of the laparoscope.

[0053] This solution is relatively simple and convenient to use, and its structure is also relatively simple. It adopts a one-way anti-reverse structure inside, which can prevent the internal gas from leaking out and avoid the leakage of body fluids, providing safer operation guarantees for minimally invasive surgery.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
