Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to a puncture device for treating kidney diseases. Background Art

[0002] The puncture device used in the treatment of kidney disease is a key medical device that uses a special puncture needle to percutaneously penetrate a specific part of the kidney to obtain tissue samples or perform local treatment. The device is widely used in scenarios such as pathological diagnosis of glomerulonephritis, sclerotherapy of renal cysts, drainage of renal abscesses, and percutaneous nephrolithotomy. When used clinically, it is necessary to strictly follow the principles of aseptic operation and select the appropriate type of puncture needle based on the patient's renal function status and coagulation function assessment. After the operation, blood pressure and hemoglobin changes must be closely monitored and possible complications such as hematuria, infection, or adjacent organ damage must be dealt with in a timely manner.

[0003] Since the abdominal wall thickness of obese patients or patients with abdominal adhesions increases significantly, and the intra-abdominal pressure fluctuates violently, traditional cannulas rely only on friction for fixation, and are prone to slippage when instruments frequently enter and exit or the patient's position changes during surgery, resulting in pneumoperitoneum collapse or accidental organ damage. In addition, when establishing pneumoperitoneum or entering the abdominal cavity, the sharp front end of the conventional sharp puncture tip is prone to penetrate the mesentery, blood vessels or adjacent organs, especially in the lack of an effective buffering mechanism between the thickened abdominal wall layers of obese patients, resulting in an increased incidence of vasovagal reflexes. For this reason, we propose a puncture device for the treatment of kidney disease. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, by providing an adsorption mechanism in the fixing plate and fixing the device by negative pressure adsorption, the pressure bearing capacity per unit area and the anti-shearing force performance are significantly improved. And by providing a multi-stage buffer mechanism, the puncture head can freely expand and contract through the buffer member, preventing accidental injury to internal organs and providing safety guarantee for the operation.

[0017] 2. In the present invention, an adjusting member and a locking member for precisely adjusting the position of the puncture head are arranged in the buffer mechanism. Through the cooperation of the adjusting member and the locking member, the sheath tube body can only move vertically within the support ring, so as to achieve the effect of adjusting the accuracy of the puncture head.

[0018] 3. In the present invention, in order to avoid damage to internal organs, a barrier ring is slidably connected to the outer wall of the sheath tube body. The barrier ring is a silica gel damping ring, which significantly reduces the axial penetration force while maintaining the puncture resistance. The puncture head can freely expand and contract through the silica gel damping ring, preventing accidental injury to internal organs.

[0019] 4. In the present invention, the adsorption mechanism and the buffer mechanism cooperate with each other. When the adsorption mechanism is locked, it drives the auxiliary ring to move upward, driving the locking block to abut against the top end surface of the inner wall of the pressing plate. Therefore, only by squeezing the inserted member inward to make the inserted member cooperate with the locking member, the position of the horizontal plate can be locked. In this way, not only the operation is convenient, but also the installation space is saved.

[0020] 5. In the present invention, when unlocking the horizontal plate, only need to reverse the annular part to make the auxiliary ring on the movable rod move downward. At this time, the supporting force received by the locking block disappears. Under the action of gravity, the first locking part and the second locking part on the locking block move downward. In this way, the locking state of the first clamping joint and the second clamping joint is released, thus realizing the rapid unlocking of the horizontal plate, which has a better effect on the actual operation.

Detailed implementation manners

[0032] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0033] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0035] Embodiment 1 further describes a puncture device for treating kidney disease proposed by the present invention, including a handheld portion 100, a mounting portion 101 is integrally formed at the bottom end of the handheld portion 100, an annular hole 102 is arranged in the mounting portion 101, a notch 103 is arranged in a circumference on the upper end surface of the mounting portion 101, the notch 103 separates the annular hole 102, a fixing plate 104 is fixedly connected to the bottom end of the mounting portion 101, an adsorption mechanism 200 fixed to the patient's body is arranged in the fixing plate 104, a buffer mechanism 300 is arranged at the bottom end of the fixing plate 104, and the adsorption mechanism 200 and the buffer mechanism 300 cooperate with each other;

[0036] The present invention further improves the prior art by providing a buffer mechanism 300, which significantly reduces the axial penetration force while maintaining the puncture resistance. The buffer member 302 allows the puncture head 302i to freely extend and retract, thereby preventing accidental injury to organs, providing safety protection for surgery, and having a better effect on protecting organs. In addition, an adsorption mechanism 200 is provided in the fixing plate 104, which can lock the puncture head 302i to prevent the puncture head 302i from sliding, thereby providing stable support for precise surgical operations.

[0037] The adsorption mechanism 200 includes an annular member 201 disposed on the handheld portion 100, a rotating member 202 matching the annular member 201 is disposed in the mounting portion 101, a movable member 203 is disposed in the fixed plate 104, and a resisting member 204 is disposed in the rotating member 202. The movable member 203 and the resisting member 204 cooperate to position the device;

[0038] Since the abdominal wall thickness of obese patients or patients with abdominal adhesions increases significantly, and the intra-abdominal pressure fluctuates violently, the traditional sleeve only relies on friction to fix it. It is easy to slip when the instruments are frequently in and out or the patient's body position changes during the operation, resulting in pneumoperitoneum collapse or accidental organ damage. The present invention provides an adsorption mechanism 200 in the fixing plate 104, fixes the device by negative pressure adsorption, and significantly improves the pressure bearing capacity and shear resistance performance per unit area. It can meet various clinical needs such as abdominal surgical incision protection, abdominal drainage tube fixation, and postoperative rehabilitation posture maintenance. In addition, it adopts zoned pressure control to disperse local stress concentration while ensuring adsorption force. This not only simplifies the surgical operation process, reduces anesthesia time and the risk of incision exposure, but also provides convenient conditions for early activities of postoperative patients, which helps to accelerate the rehabilitation process.

[0039] The buffer mechanism 300 includes an auxiliary member 301 disposed on the movable member 203, a buffer member 302 is disposed at the bottom end of the fixed plate 104, an adjusting member 303 matching the buffer member 302 is disposed in the mounting portion 101, a locking member 304 is disposed on the adjusting member 303, an inserting member 305 is disposed in the adjusting member 303, and the locking member 304 and the inserting member 305 cooperate with each other;

[0040] When the conventional sharp puncture head 302i is used to establish pneumoperitoneum or enter the abdominal cavity, its sharp front end is easy to penetrate the mesentery, blood vessels or adjacent organs, especially in the lack of effective buffering mechanism between the thickened abdominal wall layers of obese patients, resulting in an increased incidence of vascular vagal reflexes and even delayed visceral injury. To address this pain point, the present invention significantly reduces the axial penetration force while maintaining the puncture resistance by setting a multi-level buffer mechanism 300. The buffer member 302 allows the puncture head 302i to freely extend and retract to prevent accidental injury to organs, provide safety protection for surgery, and have a better effect on the protection of organs. In addition, an adsorption mechanism 200 is provided in the fixing plate 104, which can lock the puncture head 302i to prevent the puncture head 302i from sliding, and provide stable support for precise surgical operations. The invention is simple to operate, has complete functions, is non-toxic and sterile, and has a better scope of application than traditional puncture instruments:

[0041] Working principle: When using this device, an adsorption mechanism 200 is provided in the fixing plate 104, and the device is fixed by negative pressure adsorption, which significantly improves the pressure bearing capacity and shear resistance performance per unit area. It can adapt to various clinical needs such as abdominal surgical incision protection, abdominal drainage tube fixation, and postoperative recovery period posture maintenance. By setting up a multi-level buffer mechanism 300, the axial penetration force is significantly reduced while maintaining the puncture resistance. The buffer member 302 allows the puncture head 302i to retract freely to prevent accidental injury to the organs, provide safety protection for the operation, and have a better effect on the protection of the organs.

[0042] Embodiment 2

[0043] The following technical features are added on the basis of the first embodiment: the adsorption mechanism 200 includes an annular member 201 arranged on the handheld part 100, a rotating member 202 matching the annular member 201 is arranged in the mounting part 101, a movable member 203 is arranged in the fixed plate 104, a resisting member 204 is arranged in the rotating member 202, the movable member 203 and the resisting member 204 cooperate to position the device, the annular member 201 includes an annular sleeve 201a threadedly connected to the handheld part 100, the upper end of the annular sleeve 201a protrudes outward to form an annular portion 201b, the bottom end of the annular sleeve 201a is symmetrically fixedly connected with a positioning rod 201c, and the rotating member 202 It includes a sliding hole 202b arranged on the upper end surface of the annular hole 102, an annular strip 202c is rotatably connected in the annular hole 102, a connecting block 202d is fixedly connected to the upper end surface of the annular strip 202c in a circumferential manner, a rotating ring 202e is fixedly connected to the upper end surface of multiple groups of connecting blocks 202d, the rotating ring 202e protrudes inward to form a protruding portion 202f, two groups of positioning rods 201c cooperate with the protruding portion 202f, and the protruding portion 202f is arranged in the middle of the two groups of positioning rods 201c, when the annular sleeve 201a rotates forward or reversely, the positioning rod 201c conflicts with the protruding portion 202f, thereby driving the rotating ring 202e to rotate forward or reversely;

[0044] It is provided with an adsorption mechanism 200 inside the fixing plate 104, and the device is positioned and fixed through the cooperation of the movable member 203 and the abutting member 204, significantly improving the pressure bearing capacity per unit area and the shear resistance performance, and can meet various clinical needs such as abdominal surgical incision protection, abdominal drainage tube fixation, and body position maintenance during the postoperative rehabilitation period;

[0045] It can be seen from Figures 1 to 10 that its annular sleeve 201a is threadedly connected to the handheld part 100, and annular parts 201b protrude from the inner and outer walls of the annular sleeve 201a. By rotating the annular part 201b, the annular sleeve 201a is driven to rotate. The annular sleeve 201a moves downward in a rotating manner on the handheld part 100. An annular strip 202c is rotatably connected inside the mounting part 101. The annular strip 202c is provided with a rotating ring 202e through a connecting block 202d, and a protruding part 202f protrudes inward from the rotating ring 202e. Due to the rotation of the annular sleeve 201a, the positioning rod 201c at the bottom end of the annular sleeve 201a cooperates with the protruding part 202f, thereby driving the rotating ring 202e to rotate;

[0046] The movable member 203 includes an annular cavity 203a provided inside the fixing plate 104. A piston plate 203b is slidably connected inside the annular cavity 203a. An opening 203c is provided around the bottom end of the annular cavity 203a, and suction cups 203d are installed corresponding to the outside of the opening 203c. An activity rod 203e is fixedly installed in a circular pattern on the upper end surface of the piston plate 203b. The activity rod 203e passes through the fixing plate 104 and is provided in the notch 103. An activity groove 203f is provided on the outer wall of the activity rod 203e. The activity groove 203f is composed of an inclined surface 203g and an inclined surface 203h. The activity groove 203f is greater than the height of the annular strip 202c in the vertical direction;

[0047] It can be seen from Figures 1 to 5 that an annular cavity 203a is formed inside the fixing plate 104. An annular piston plate 203b is slidably connected inside the annular cavity 203a. The piston plate 203b is driven to move in the vertical direction through the activity rod 203e. When the suction cup 203d on the fixing plate 104 comes into contact with the patient's body, due to the movement of the piston plate 203b inside the annular cavity 203a, the fixing plate 104 is adsorbed on the patient's body through the formation of negative pressure. An activity groove 203f is provided on the outer wall of the activity rod 203e. The activity groove 203f is of a V-shaped structure. The activity groove 203f is composed of an inclined surface 203g and an inclined surface 203h. The activity groove 203f is greater than the height of the annular strip 202c in the vertical direction. In this way, when the annular strip 202c rotates, the abutting member 204 is driven to rotate synchronously. At this time, the abutting member 204 comes into contact with the movable member 203;

[0048] The resisting member 204 includes a connecting portion 204a fixed in a circumferential manner inside the annular strip 202c, a blocking block 204b is fixedly connected to the upper end surface of the connecting portion 204a, a blocking block 204c is fixedly connected to the lower end surface of the connecting portion 204a, the blocking block 204b cooperates with the inclined surface 203g, and the blocking block 204c cooperates with the inclined surface 203h, the auxiliary member 301 includes an auxiliary ring 301a fixedly connected to the movable rod 203e, a compression spring 301b is symmetrically fixedly connected to the upper end surface of the auxiliary ring 301a, the compression spring 301b is a carbon spring with high strength and convenient for daily use, one end of the compression spring 301b is fixedly connected to the lower end surface of the mounting portion 101, and an arc hole 301c is correspondingly provided on the upper end surface of the auxiliary ring 301a;

[0049] Depend on Figures 1 to 10 It can be seen that four groups of joints 204a are fixedly connected in a circumference in the annular strip 202c, and the joints 204a are respectively formed with a blocking block 1 204b and a blocking block 2 204c, which are respectively arranged at the two ends of the joint 204a, and the joint 204a is larger than the length of the movable groove 203f. When the annular strip 202c rotates, the blocking block 1 204b and the blocking block 204c on the joint 204a are driven to move synchronously. When moving clockwise, the blocking block 204c cooperates with the inclined surface 203h, thereby driving the movable rod 203e to move downward. When rotating counterclockwise, the blocking block 1 204b cooperates with the inclined surface 1 203g, thereby driving the movable rod 203e to move upward. Therefore, when the movable rod 203e moves in the vertical direction, its compression spring 301b is deformed;

[0050] Working principle: As can be seen from Embodiment 1, during use, the suction cup 203d on the fixed plate 104 adheres to the patient's body. By rotating the annular portion 201b, the annular sleeve 201a is driven to rotate. The annular sleeve 201a makes a rotational downward movement on the handheld portion 100. Due to the rotation of the annular sleeve 201a, the positioning rod 201c at the bottom of the annular sleeve 201a cooperates with the protruding portion 202f, thereby driving the rotating ring 202e to rotate. When the rotating ring 202e rotates, it drives the engaging portion 204a in the annular strip 202c to rotate. The blocking block one 204b cooperates with the inclined surface one 203g, thereby driving the movable rod 203e to move upward. At this time, the compression spring 301b deforms. When the movable rod 203e moves upward, it drives the piston plate 203b to move in the vertical direction. When the suction cup 203d on the fixed plate 104 comes into contact with the patient's body, since the piston plate 203b moves in the annular cavity 203a, the fixed plate 104 is adsorbed on the patient's body through the formation of negative pressure. In this way, the pressure bearing capacity per unit area and the anti-shearing force performance are improved, and it can meet various clinical needs such as abdominal surgical incision protection, abdominal drainage tube fixation, and body position maintenance during the postoperative rehabilitation period. Moreover, multiple groups of suction cups 203d are used for partition pressure regulation to disperse local stress concentration while ensuring the adsorption force.

[0051] Embodiment Three

[0052] On the basis of Embodiment Two, the following technical features are added: The buffer mechanism 300 includes an auxiliary member 301 provided on the movable member 203. A buffer member 302 is provided at the bottom end of the fixed plate 104. An adjusting member 303 cooperating with the buffer member 302 is provided in the mounting portion 101. A locking member 304 is provided on the adjusting member 303. An inserting member 305 is provided in the adjusting member 303. The locking member 304 and the inserting member 305 cooperate with each other. The buffer member 302 includes a support ring 302a fixedly connected to the bottom of the fixed plate 104. An activity ring 302b is rotatably connected in the fixed plate 104. A sheath tube main body 302c moves vertically in the activity ring 302b. A limiting groove 302d is provided on the inner wall of the support ring 302a. A limiting block 302e is slidably connected in the limiting groove 302d. The limiting block 302e is fixedly connected to the outer wall of the sheath tube main body 302c. An arc groove 302f is provided on the outer wall of the sheath tube main body 302c. A positioning portion 302g is integrally formed on the inner wall of the activity ring 302b. The positioning portion 302g is slidably connected to the arc groove 302f correspondingly. A blocking ring 302h is slidably connected to the outer wall of the sheath tube main body 302c. One end of the blocking ring 302h is fixedly connected with a puncture head 302i;

[0053] From Figures 1 to 8It can be seen that a movable ring 302b is rotatably connected inside the fixing plate 104. When the movable ring 302b rotates, the positioning part 302g inside the movable ring 302b is correspondingly slidably connected in the arc-shaped groove 302f. And because a limiting block 302e is fixed on the side wall of the sheath tube body 302c and the limiting block 302e is slidably connected in the limiting groove 302d, the sheath tube body 302c can only move vertically in the support ring 302a, so as to achieve the effect of adjusting the puncture head 302i. And in order to prevent accidental injury to organs, a blocking ring 302h is slidably connected to the outer wall of the sheath tube body 302c, and one end of the blocking ring 302h is fixedly connected to the puncture head 302i. Thus, by setting the buffer mechanism 300, while maintaining the puncture resistance, the axial penetration force is significantly reduced. It enables the puncture head 302i to freely expand and contract through the buffer member 302, preventing accidental injury to organs, providing safety guarantee for the operation, and having a better effect on the protection of organs;

[0054] The adjusting member 303 includes a sector-shaped hole 303a provided in the installation part 101. A rotating ring 202e is fixedly connected to the position of the installation part 101 with a cross plate 303b. The cross plate 303b is correspondingly arranged in the sector-shaped hole 303a. The locking member 304 includes a telescopic rod 304a fixedly connected to the upper end face of the cross plate 303b. The telescopic rod 304a is correspondingly arranged in the arc-shaped hole 301c. The extending end of the telescopic rod 304a is arranged above the arc-shaped hole 301c. The extending end of the telescopic rod 304a is fixedly connected to a locking block 304b. The locking block 304b is larger than the width of the arc-shaped hole 301c. The upper end face of the locking block 304b is symmetrically and fixedly connected with a first locking part 304c and a second locking part 304d;

[0055] It can be seen from Figures 3 to 10 that a cross plate 303b is fixedly connected to the rotating ring 202e. By driving the movable ring 302b to rotate through the cross plate 303b, the effect of accurately adjusting the length of the puncture head 302i is achieved. A locking member 304 is fixedly installed on the cross plate 303b, and the locking member 304 is inside the arc-shaped hole 301c of the auxiliary ring 301a. When the cross plate 303b rotates, it drives the locking member 304 to rotate in the arc-shaped hole 301c. Since the extending end of the telescopic rod 304a is arranged above the arc-shaped hole 301c and the locking block 304b is larger than the width of the arc-shaped hole 301c, when the movable rod 203e drives the auxiliary ring 301a to move upward, the locking block 304b moves upward synchronously;

[0056] The inserting member 305 includes a pressing plate 305a integrally formed on the upper end surface of the horizontal plate 303b. The pressing plate 305a is slidably connected to an inserting plate 305b in the horizontal direction. On both sides of the inserting plate 305b, a first clamping block 305c and a second clamping block 305d are integrally formed respectively. The first clamping block 305c and the second clamping block 305d are fixedly connected to both sides of the pressing plate 305a respectively. One end of the pressing plate 305a extends to form a first clamping joint 305e and a second clamping joint 305f. The first clamping joint 305e and the second clamping joint 305f are made of soft rubber material. A compression space 305h is formed between the first clamping joint 305e and the second clamping joint 305f. The first clamping joint 305e cooperates with the first locking part 304c, and the second clamping joint 305f cooperates with the second locking part 304d;

[0057] As can be seen from Figures 4 to 10 it, an L-shaped pressing plate 305a is formed on the upper end surface of the horizontal plate 303b. A rectangular inserting plate 305b is slidably connected inside the pressing plate 305a. A first clamping block 305c and a second clamping block 305d are formed on both sides of the inserting plate 305b respectively. The position of the inserting plate 305b is limited by the first clamping block 305c and the second clamping block 305d. Therefore, the staff can move the inserting plate 305b to its position in the pressing plate 305a, so as to lock the device. Before locking the fixing plate 104, the inserting plate 305b is pulled outwards. When locking the fixing plate 104, its auxiliary ring 301a moves upwards, driving the locking block 304b to abut against the top end surface of the inner wall of the pressing plate 305a. At this time, the inserting plate 305b is squeezed inwards, so that the first clamping joint 305e cooperates with the first locking part 304c, and the second clamping joint 305f cooperates with the second locking part 304d. Since the first clamping joint 305e and the second clamping joint 305f are made of soft rubber material, the compression space 305h decreases at this time. Then, the first locking part 304c and the second locking part 304d limit the inserting plate 305b, so as to lock the position of the horizontal plate 303b. In this way, the length of the puncture head 302i can be adjusted as needed;

[0058] Moreover, in order to avoid damage to the internal organs, a blocking ring 302h is slidably connected to the outer wall of the sheath body 302c. The blocking ring 302h is a silica gel damping ring. One end of the blocking ring 302h is fixedly connected to a puncture head 302i, which significantly reduces the axial penetration force while maintaining the puncture resistance. The puncture head 302i can freely expand and contract through the silica gel damping ring, preventing accidental injury to the internal organs;

[0059] Working principle: As can be seen from Embodiment 2, before the fixing plate 104 is positioned, the plug plate 305b is first pulled outwards. When the positioning of the fixing plate 104 is completed and the position of the puncture head 302i needs to be adjusted, only the cross plate 303b needs to be rotated. The cross plate 303b drives the movable ring 302b to rotate. Since the positioning part 302g inside the movable ring 302b is slidably connected to the arc-shaped groove 302f correspondingly, and since the limiting block 302e is fixed on the side wall of the sheath tube main body 302c and the limiting block 302e is slidably connected to the limiting groove 302d, the sheath tube main body 302c can only move vertically within the support ring 302a, thereby achieving the effect of adjusting the accuracy of the puncture head 302i. Moreover, a barrier ring 302h is slidably connected to the outer wall of the sheath tube main body 302c, and the barrier ring 302h is a silicone damping ring. The silicone damping ring enables the puncture head 302i to freely expand and contract, preventing accidental injury to organs and providing safety guarantee for the operation;

[0060] After the adjustment is completed, due to the positioned fixing plate 104, the auxiliary ring 301a is driven to move upwards, driving the locking block 304b to abut against the top end surface of the inner wall of the pressing plate 305a. Only by pressing the plug plate 305b inwards, the first card joint 305e is matched with the first locking part 304c, and the second card joint 305f is matched with the second locking part 304d. Since the first card joint 305e and the second card joint 305f are made of soft rubber material, the compression space 305h decreases at this time. Then, the first locking part 304c and the second locking part 304d limit the plug plate 305b, thereby locking the position of the cross plate 303b and achieving the result of precisely adjusting the puncture head 302i;

[0061] When unlocking is required, only the annular part 201b needs to be reversed to make the auxiliary ring 301a on the movable rod 203e move downwards. At this time, the supporting force received by the locking block 304b disappears. Under the action of gravity, the first locking part 304c and the second locking part 304d on the locking block 304b move downwards. In this way, the locking states of the first card joint 305e and the second card joint 305f are released, thereby realizing the unlocking of the cross plate 303b.

[0062] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
