The puncture mechanism includes a puncture needle, a pressure cap, and an outer tube. During the insertion of the instrument into the skin tissue, two pressure sensors monitor the tissue resistance of the outer tube in real time.

Description

Technical Field

[0001] This invention relates to the field of sealing puncture device technology, specifically a snap-on sealing puncture device with an outer sheath. Background Technology

[0002] In minimally invasive human medical surgery, once a disease is found in the human body that requires surgery or removal, the first thing to be used during the operation is a puncture device, which is a surgical instrument that punctures the abdominal wall and provides a channel for other surgical instruments to enter the body cavity.

[0003] During laparoscopic surgery, the cold endoscope, once inserted into the warm body cavity, will condense on its surface due to the temperature difference, causing momentary blurring of the vision. To solve this problem, the surgeon must frequently withdraw the endoscope and wipe it with iodine-soaked gauze or a special anti-fogging agent, or rely on additional, non-standard flushing tubing to inject warm saline for endoscope flushing. This process not only severely disrupts the continuity of the surgery and increases the operation time, but also repeatedly compromises the airtightness between the endoscope and the external tubing during the repeated insertion and removal, causing fluctuations in pneumoperitoneum pressure and affecting the stability of the surgical space. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted in this invention is as follows:

[0006] A snap-fit ​​sealing puncture device with an outer tube includes a puncture mechanism, an auxiliary mechanism, and an injection mechanism. The puncture mechanism includes a puncture needle, a pressure cap, and an outer tube. The pressure cap and the outer tube are slidably sleeved on the outside of the puncture needle. The pressure cap is fastened to the top of the outer tube. The auxiliary mechanism includes a capsule embedded on the outside of the outer tube, a spacer ring fixed to the inside of the capsule, a cleaning chamber and a lubrication chamber formed inside the capsule, two flushing tubes penetrating the bottom of the capsule and communicating with the cleaning chamber, two solenoid valves respectively installed on the two flushing tubes, and a penetrating... The device comprises four lubrication pipes at the top of the bladder and connected to the lubrication cavity, four solenoid valves II respectively installed on the four lubrication pipes, and an injection mechanism. The injection mechanism includes a water pipe and a liquid pipe passing through the top of the bladder, a connecting sleeve connecting the water pipe and the liquid pipe, an inlet pipe passing through the front side of the connecting sleeve, a rotatable adjusting box embedded inside the connecting sleeve, a through hole opened on the adjusting box, two tactile switches fixedly connected to the top of the connecting sleeve, two solenoid valves I connected in series, and four solenoid valves II connected in series. The solenoid valves I and II are electrically connected to the two tactile switches respectively.

[0007] By adopting the above technical solution, after the instrument is inserted into the tissue, the directional box is rotated to align the through hole with the liquid tube, and lubricating grease is injected through the inlet tube. The lubricating grease enters the lubrication chamber through the liquid tube and is diverted to the gap between the puncture needle and the outer tube through four lubrication tubes to form a "wet seal," providing conditions for the movement of the puncture needle. The directional box is rotated again to align the through hole with the water tube, and warm physiological saline is injected. The physiological saline enters the cleaning chamber and is diverted by two flushing tubes to flush the lens in a directional manner, achieving rapid defogging and maintaining a clear field of vision. This integrated process avoids the repeated removal of the puncture needle, which not only improves the smoothness and comfort of the operation, but also eliminates the decrease in air tightness caused by dry friction, effectively maintaining stable pneumoperitoneum pressure and enhancing surgical safety.

[0008] In a preferred embodiment, the present invention may be further configured such that the lubrication chamber is located outside the cleaning chamber, and the volume of the cleaning chamber is equal to the volume of the lubrication chamber.

[0009] In a preferred embodiment, the present invention can be further configured as follows: two flushing pipes are vertically symmetrical, and four lubrication pipes are equally spaced and arranged in a ring, wherein the flushing pipes and lubrication pipes are both embedded in the inner wall of the outer pipe.

[0010] In a preferred embodiment, the present invention can be further configured such that the inner wall of the outer tube has a plurality of cavities suitable for the installation of solenoid valve one and solenoid valve two.

[0011] In a preferred embodiment, the present invention can be further configured such that the bodies of the water pipe and the liquid pipe are both embedded inside the outer pipe, and the top ends of both extend to the front side of the outer pipe.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the directional box consists of two discs and an arc plate, the arc plate is vertically fixed between the two discs, an inlet is provided between the two discs, the inlet is located on the front side of the arc plate, and the through hole is located on the arc plate.

[0013] In a preferred embodiment, the present invention can be further configured such that a pointer is fixedly connected to the top of the directional box, and the pointer is concentrically positioned with the disk.

[0014] In a preferred embodiment, the present invention may be further configured such that: a locking assembly is provided on the outer side of the outer tube, the locking assembly including a locking ring and a soft pad movably sleeved on the outer side of the outer tube, two locking plates slidably penetrating through the inner sidewall of the locking ring, a U-shaped rod slidably penetrating through the outer side of the locking ring and fixedly connected to the locking plates, and two springs movably sleeved at both ends of the U-shaped rod and fixedly connected to the outer wall of the locking plates, wherein the top of the soft pad is fixedly connected to the bottom of the locking ring.

[0015] In a preferred embodiment, the present invention can be further configured such that: the outer wall of the outer tube is provided with a plurality of annular grooves, the plurality of annular grooves are equally spaced and arranged in a row, and the annular grooves are suitable for clamping.

[0016] In a preferred embodiment, the present invention can be further configured such that: pressure sensors are embedded in both the front and rear side walls of the outer tube, the pressure sensors are located at the top of the bladder, and the pressure sensors are electrically connected to an external PLC.

[0017] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0018] 1. In this invention, after the instrument is inserted into the tissue, the aligning box is rotated to align the through hole with the liquid tube, and lubricating grease is injected through the inlet tube; the lubricating grease enters the lubrication chamber through the liquid tube, and is diverted to the gap between the puncture needle and the outer tube through four lubrication tubes to form a "wet seal", providing conditions for the movement of the puncture needle. The aligning box is rotated again to align the through hole with the water tube, and warm physiological saline is injected; the physiological saline enters the cleaning chamber, and is diverted by two flushing tubes to flush the lens in a directional manner, achieving rapid defogging and maintaining a clear field of vision. This integrated process avoids the repeated operation of pulling out the puncture needle, which not only improves the smoothness of the operation and the comfort of operation, but also eliminates the decrease in air tightness caused by dry friction, effectively maintains stable pneumoperitoneum pressure, and enhances the safety of the operation.

[0019] 2. In this invention, when the lens on the puncture needle is repeatedly atomized, the surgeon can cut off the supply of mild saline to the irrigation tube by pressing a light-touch switch connected to a solenoid valve, thus avoiding waste of saline and making the surgical process smoother.

[0020] 3. In this invention, during the insertion of the instrument into the skin tissue, two pressure sensors monitor the tissue resistance experienced by the outer tube in real time. When the sensor data drops sharply, it indicates that the outer tube has successfully broken through the tissue barrier and entered the body cavity. Then, grease is injected to deform the capsule and seal the puncture site. At the same time, it also prevents subcutaneous emphysema. Then, the sliding locking ring slides down to make the soft pad fit the body surface. This double clamping inside and outside the body improves the stability of the outer tube and makes the puncture needle operation more stable. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0036] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0037] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a snap-fit ​​sealing puncture device with an outer sleeve.

[0038] Example 1:

[0039] Combination Figure 1-7 As shown, the present invention provides a snap-on sealing puncture device with an outer tube, including a puncture mechanism 100, an auxiliary mechanism 200 and an injection mechanism 300. The puncture mechanism 100 includes a puncture needle 110, a pressure cap 120 and an outer tube 130. The pressure cap 120 and the outer tube 130 are slidably sleeved on the outside of the puncture needle 110, and the pressure cap 120 is fastened to the top of the outer tube 130.

[0040] The auxiliary mechanism 200 includes a bladder 210 embedded on the outside of the outer tube 130, a spacer ring 220 fixed inside the bladder 210, a cleaning chamber 230 and a lubrication chamber 240 formed inside the bladder 210, two flushing pipes 250 passing through the bottom of the bladder 210 and communicating with the cleaning chamber 230, two solenoid valves 260 respectively installed on the two flushing pipes 250, four lubrication pipes 270 passing through the top of the bladder 210 and communicating with the lubrication chamber 240, and four solenoid valves 280 respectively installed on the four lubrication pipes 270.

[0041] The injection mechanism 300 includes a water pipe 310 and a liquid pipe 320 passing through the top of the bladder 210, a connecting sleeve 330 connecting the water pipe 310 and the liquid pipe 320, an inlet pipe 340 passing through the front side of the connecting sleeve 330, a rotatable adjustment box 350 embedded inside the connecting sleeve 330, a through hole 360 ​​opened on the adjustment box 350, and two tactile switches 370 fixedly connected to the top of the connecting sleeve 330.

[0042] Two solenoid valves 1 (260) are connected in series, and four solenoid valves 2 (280) are connected in series. Solenoid valves 1 (260) and 2 (280) are electrically connected to two tactile switches 370 respectively.

[0043] Furthermore, the lubrication chamber 240 is located outside the cleaning chamber 230, and the volume of the cleaning chamber 230 is equal to the volume of the lubrication chamber 240. This structural design allows the cleaning chamber and the lubrication chamber to be rationally distributed inside the capsule, ensuring that the cleaning and lubrication functions can be carried out independently, while making full use of the internal space of the capsule.

[0044] Furthermore, the two flushing tubes 250 are vertically symmetrical, and the four lubrication tubes 270 are equally spaced and arranged in a ring. Both the flushing tubes 250 and the lubrication tubes 270 are embedded in the inner wall of the outer tube 130. The inner wall of the outer tube 130 has multiple cavities suitable for the installation of solenoid valve 1 260 and solenoid valve 280. The layout design of the flushing tubes 250 allows the two flushing tubes 250 to fully flush the lens when atomization occurs at the puncture needle 110 lens position, simply by rotating the puncture needle 110. The layout design of the lubrication tubes 270 provides conditions for uniform lubrication of the outer wall surface of the puncture needle 110.

[0045] Furthermore, the bodies of water pipe 310 and liquid pipe 320 are both embedded inside the outer pipe 130, and the tops of both extend to the front of the outer pipe 130. This structural design can improve the installation firmness of water pipe 310 and liquid pipe 320, and also allows for the injection of mild saline or lubricating grease.

[0046] Furthermore, the directional box 350 consists of two discs 351 and an arc plate 352. The arc plate 352 is vertically fixed between the two discs 351. An inlet 353 is provided between the two discs 351. The inlet 353 is located on the front side of the arc plate 352. A through hole 360 ​​is located on the arc plate 352. With this structural design, mild saline or lubricating grease can be injected into the water pipe 310 or liquid pipe 320 in a targeted manner.

[0047] Furthermore, a pointer 600 is fixed to the top of the directional box 350. The pointer 600 is concentrically set with the disc 351. The pointer 600 is set so that the doctor can connect the through hole 360 ​​on the directional box 350 to the water pipe 310 or the liquid pipe 320.

[0048] Example 2:

[0049] Combination Figure 1 and Figure 7 As shown, based on Embodiment 1, a locking assembly 400 is provided on the outer side of the outer tube 130. The locking assembly 400 includes a locking ring 410 and a soft pad 420 movably sleeved on the outer side of the outer tube 130, two clamping plates 430 slidingly penetrating the inner wall of the locking ring 410, a U-shaped rod 440 slidingly penetrating the outer side of the locking ring 410 and fixedly connected to the clamping plates 430, and two springs 450 movably sleeved on both ends of the U-shaped rod 440 and fixedly connected to the outer wall of the clamping plates 430. The top of the soft pad 420 is fixedly connected to the bottom of the locking ring 410. After the bladder 210 seals the puncture site from the body, the two U-shaped rods 440 are pulled outward, and then the clamping plates 430 separate from the annular groove, so that the locking ring 410 can slide downward until the soft pad 420 is in contact with the body surface, thereby achieving double clamping from the inside and outside of the body, thereby improving the installation firmness of the outer tube 130.

[0050] Specifically, the outer wall of the outer tube 130 is provided with multiple annular grooves. The multiple annular grooves are equally spaced and arranged in a row. The annular grooves are suitable for the clamping plate 430 to clamp. The annular grooves provide conditions for the clamping plate 430 to lock the outer tube 130.

[0051] Example 3:

[0052] Combination Figure 1 As shown, in the above embodiment, pressure sensors 500 are embedded in both the front and rear side walls of the outer tube 130. The pressure sensors 500 are located at the top of the bladder 210 and are electrically connected to an external PLC. The setting of the pressure sensors 500 makes it convenient for medical personnel to operate the device.

[0053] Working principle and usage process of this invention:

[0054] In actual operation, the puncture needle 110, pressure cap 120 and outer tube 130 are first assembled into one unit and inserted into the patient's body surface tissue through the puncture point. During this process, two pressure sensors 500 monitor the tissue resistance encountered by the outer tube 130 in real time. When the sensor data drops sharply, it indicates that the outer tube 130 has successfully broken through the tissue barrier and entered the body cavity.

[0055] Subsequently, the operator rotates the adjustment box 350 so that its through hole 360 ​​is aligned with the liquid tube 320, and injects grease through the inlet tube 340. The grease enters the lubrication chamber 240 along the liquid tube 320, and is diverted through the four lubrication tubes 270 to the gap between the puncture needle 110 and the outer tube 130 to achieve a "wet seal". After lubrication is completed, the operator presses the light touch switch 370 connected to the solenoid valve 280 to cut off the grease supply. At this time, the lubrication chamber 240 pushes the cyst body 210 to deform under the residual pressure, tightly fitting the puncture path. This deformation result achieves dynamic sealing of the puncture point on the one hand, and prevents subcutaneous emphysema on the other hand.

[0056] Next, rotate the adjustment box 350 again to connect the through hole 360 ​​with the water pipe 310. Warm saline solution is injected through the inlet pipe 340. The saline solution is injected into the cleaning chamber 230 along the water pipe 310. In the initial state, the solenoid valve 260 is kept closed and the irrigation fluid is temporarily stored in the chamber. When the lens at the tip of the puncture needle 110 fogs up and affects the field of vision, the operator presses the touch switch 370 connected to the solenoid valve 260 to open the valve. The saline solution then directionally rinses the lens surface, quickly eliminates fog, and ensures a clear surgical field of vision.

[0057] This integrated procedure avoids the need to repeatedly remove the puncture needle 110 during surgery for wiping or resealing, which improves the smoothness of the operation and the comfort of the surgeon. It also eliminates the wear and tear on the seals and the decrease in airtightness caused by dry friction, effectively maintains stable pneumoperitoneum pressure, and enhances the safety of the surgical procedure.

[0058] This method effectively avoids situations where the doctor removes the puncture needle, improving surgical comfort and preventing damage to the airtightness caused by dry friction, thus avoiding fluctuations in pneumoperitoneum pressure and making the surgery safer.

[0059] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
