Description

Technical Field

[0001] This invention relates to the field of laparoscopic instrument support technology, and specifically to a laparoscopic fixation device for minimally invasive laparoscopic surgery. Background Technology

[0002] Laparoscopic surgery is the mainstream minimally invasive abdominal surgery procedure in clinical practice. Due to its advantages such as being minimally invasive and allowing for rapid postoperative recovery, it is widely used in the diagnosis and treatment of abdominal diseases. The laparoscopic fixation device, as an important auxiliary instrument in minimally invasive abdominal surgery, is mainly used to support and fix the laparoscope and adjust its position in multiple dimensions during the operation. It is a key supporting device for ensuring the stable positioning of the laparoscope and providing the surgeon with a clear surgical field.

[0003] Existing technology discloses a laparoscopic fixation device for minimally invasive laparoscopic surgery, application number CN202110561126.6, comprising: a lifting adjustment component for adjusting the vertical positioning height of the laparoscope; a horizontal adjustment component connected to the lifting adjustment component for adjusting the lateral positioning position of the laparoscope; an angle adjustment component connected to the horizontal adjustment component for adjusting the insertion and positioning angle of the laparoscope; and a feed component connected to the angle adjustment component for feeding and inserting the laparoscope. The horizontal adjustment component includes a cantilever frame and a large gear assembled on a coaxial axis, wherein the cantilever frame and the large gear do not rotate simultaneously. In summary, the present invention, through the mutually cooperating lifting adjustment component, horizontal adjustment component, and angle adjustment component, can effectively realize multi-angle operation and adjustment of the laparoscope, thereby making minimally invasive laparoscopic surgery more convenient.

[0004] However, existing technologies, especially this particular solution, still have the following problems: The vertical and horizontal positions are adjusted separately, making it impossible to achieve simultaneous unlocking and linkage adjustment with one hand. The operation steps are cumbersome and the operation is not convenient. The locking mechanism relies on gears and cantilever frame to achieve positioning. The locking force is prone to radial torque transmission. When adjusting the locking, it is easy to cause the laparoscope to shift, resulting in shaking of the surgical field. The axial feed of the laparoscopy is only achieved through the mechanical feed component, without a sensor-based intelligent locking logic. It does not form a safe control mode of holding and unlocking and releasing and locking, which is prone to intraoperative misadjustment and free movement of the laparoscope. It only achieves radial clamping of the laparoscope and does not set up an axial limit locking structure, which makes the laparoscope prone to axial movement and slippage, and the positioning stability is insufficient. The adjustment and control parts lack a protective structure to prevent accidental touch, making it easy for accidental touches during surgery to trigger adjustment movements and disrupt the stable positioning of the laparoscope. Summary of the Invention

[0005] The purpose of this invention is to provide a technical solution to address the problems in the prior art mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A laparoscopic fixation device for minimally invasive laparoscopic surgery includes: a movable base, a vertical support column, and a horizontal adjustment arm; The vertical support column is fitted with a sliding mounting seat that can slide along the column axis. The horizontal adjustment arm is slidably mounted on the sliding mounting seat, and the end of the horizontal adjustment arm is connected to an elastic support arm. The sliding mounting base is equipped with two sets of one-handed clutch locking mechanisms, which are used for sliding adjustment of the sliding mounting base on the vertical support column and sliding adjustment of the sliding mounting base on the horizontal adjustment arm, respectively. The one-handed clutch locking mechanism is configured as follows: It unlocks when pressed with one hand and automatically locks when released, with the locking force released axially and no radial torque transmission; when unlocked by pressing with one finger, the positions of the sliding mounting base and the lateral adjustment arm can be adjusted simultaneously. The end of the elastic support arm is equipped with a locking claw via a clamping bracket. The locking claw is used to lock and clamp the laparoscopic assembly. An adjusting rod is connected to the locking jaws. An electromagnetic locking assembly is provided on the adjusting rod, which can be slidably adjusted and locked in place.

The laparoscopic instrument has a sensor switch inside the handle's grip hole. This sensor switch is electrically connected to the electromagnetic locking assembly and is configured as follows: When the sensor switch detects a finger grip signal, it controls the electromagnetic locking component to unlock, allowing the electromagnetic locking component to move and adjust on the adjustment rod; when the sensor switch does not detect a finger grip signal, it controls the electromagnetic locking component to lock, restricting the movement and adjustment of the electromagnetic locking component on the adjustment rod.

[0007] Preferably, the single-handed clutch locking mechanism includes a telescopic push rod and a toothed pressure block. The toothed pressure block is installed at the telescopic end of the telescopic push rod. A support spring is provided between the telescopic rod and the toothed pressure block.

[0008] Preferably, the telescopic push rod is in the extended state in the initial state, and the telescopic push rod is in the retracted state when the single-handed clutch locking mechanism is triggered, thereby realizing the vertical and horizontal position adjustment of the locking claw with one hand.

[0009] Preferably, the single-handed clutch locking mechanism includes an adjustment handle, which is located on the lateral adjustment arm near the locking jaw. The adjustment handle is equipped with an adjustment button, which is used to simultaneously trigger the telescopic push rods of the two sets of single-handed clutch locking mechanisms for adjustment.

[0010] Preferably, the adjustment handle is also provided with an anti-accidental touch button, which is offset from the adjustment button. The anti-accidental touch button has an on / off mode.

[0011] Preferably, the adjustment button is configured as a resettable mechanical push switch, and the adjustment handle is connected to two sets of single-handed clutch locking mechanisms via clutch cables. The clutch cables are used to synchronously transmit the pressing action of the adjustment button to the two sets of telescopic push rods, so as to realize the synchronous unlocking of the two sets of clutch locking mechanisms.

When the electromagnetic coil is de-energized, the return spring pushes the locking pin into the locking slot, thus axially locking the electromagnetic locking assembly on the adjusting rod.

[0014] Preferably, the distal retaining ring is detachably sleeved on the endoscope tube of the laparoscopic instrument, and the distal retaining ring is supported on the handle of the laparoscopic instrument. The inductive switch is a capacitive touch sensor switch.

Two sets of single-handed clutch locking mechanisms can be pressed to unlock and released automatically to lock with one hand. The locking force is released axially without radial torque transmission, and the positions of the sliding mounting seat and the lateral adjustment arm can be adjusted simultaneously.

Detailed Implementation

[0020] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0021] The invention provides, for example Figures 1 to 6 As shown, a laparoscopic fixation device for minimally invasive laparoscopic surgery includes: The mobile base 11, the vertical support column 12, and the horizontal adjustment arm 14; The vertical support column 12 is fitted with a sliding mounting seat 13 that can slide along the column axis. The horizontal adjustment arm 14 is slidably mounted on the sliding mounting seat 13. The end of the horizontal adjustment arm 14 is connected to an elastic support arm 16. The sliding mounting base 13 is provided with two sets of one-handed clutch locking mechanisms 15, which are used for sliding adjustment of the sliding mounting base 13 on the vertical support column 12 and sliding adjustment of the sliding mounting base 13 on the horizontal adjustment arm 14, respectively. The one-handed clutch locking mechanism 15 is configured as follows: It unlocks when pressed with one hand and automatically locks when released, with the locking force released axially and no radial torque transmission; when unlocked by pressing with one finger, the positions of the sliding mounting base 13 and the lateral adjusting arm 14 can be adjusted simultaneously. The end of the elastic support arm 16 is equipped with a locking claw 18 via a clamping bracket 17. The locking claw 18 is used to lock and clamp the laparoscopic assembly. An adjusting rod 21 is connected to the locking jaw 18. An electromagnetic locking assembly 22 that can be slidably adjusted and locked is provided on the adjusting rod 21. A distal retaining ring 23 is connected to the electromagnetic locking assembly 22. The distal retaining ring 23 is used to achieve axial limiting and locking of the laparoscopic instruments. The handle of the laparoscopic instrument has a hand-held hole equipped with a sensor switch 24, which is electrically connected to the electromagnetic locking assembly 22 and is configured as follows: When the inductive switch 24 senses a finger grip signal, it controls the electromagnetic locking component 22 to unlock, allowing the electromagnetic locking component 22 to move and adjust on the adjusting rod 21; when the inductive switch 24 does not sense a finger grip signal, it controls the electromagnetic locking component 22 to lock, restricting the movement and adjustment of the electromagnetic locking component 22 on the adjusting rod 21.

[0022] Working principle: Based on the movable base 11, the vertical and horizontal positions of the laparoscope are adjusted by relying on the sliding mounting seat 13 and the horizontal adjustment arm 14. Two sets of single-handed clutch locking mechanisms 15 can be pressed to unlock and released to automatically lock with one hand. The locking force is released axially and there is no radial torque transmission. The positions of the sliding mounting seat 13 and the horizontal adjustment arm 14 can be adjusted simultaneously. The elastic support arm 16 adapts to the surgical posture, the locking claw 18 clamps and fixes the laparoscope, and the induction switch 24 at the handle detects the grip signal and controls the electromagnetic locking component 22 to unlock, slide or lock on the adjustment rod 21. With the help of the distal retaining ring 23, the axial limit locking of the laparoscope is completed.

[0023] The single-handed clutch locking mechanism 15 enables simultaneous single-handed position adjustment, which is easy to operate and locks without radial torque, thus preventing the laparoscope lens from shifting. The induction-controlled electromagnetic locking component 22, together with the distal retaining ring 23, enables automatic axial locking and precise adjustment of the laparoscope, ensuring stable fixation. The entire device can quickly adjust and stably fix the laparoscope, replacing manual support and improving the stability and convenience of surgical operations.

[0024] Regarding the core components of the single-handed clutch locking mechanism 15, it relies on the telescopic push rod 151, the toothed pressure block 152, and the support spring 153, and cooperates with the locking teeth 19 of the vertical support column 12 to achieve the locking operation. The single-handed clutch locking mechanism 15 includes a telescopic push rod 151 and a toothed pressure block 152. The toothed pressure block 152 is installed at the telescopic end of the telescopic push rod 151. A support spring 153 is provided between the telescopic rod of the telescopic push rod 151 and the toothed pressure block 152. The side of the support column is provided with locking teeth 19. The telescopic push rod 151 supports the toothed pressure block 152 to cooperate with the locking teeth 19 to achieve the locking function.

[0025] It should be noted that the extension and retraction state of the telescopic push rod 151 directly determines the locking effect. Initially, it extends to lock, and when triggered, it retracts to unlock, thereby achieving vertical and horizontal position adjustment of the locking jaw 18. In the initial state, the telescopic push rod 151 is in the extended state. When the one-handed clutch locking mechanism 15 is triggered, the telescopic push rod 151 is in the retracted state, thus achieving one-handed vertical and horizontal position adjustment of the locking jaw 18.

[0026] To achieve synchronous operation of the two locking mechanisms, an adjustment handle 155 is provided at the end of the lateral adjustment arm 14 near the locking jaw 18. The two sets of telescopic push rods 151 are triggered by the adjustment button 156. The single-handed clutch locking mechanism 15 includes the adjustment handle 155, which is located on the lateral adjustment arm 14 near the locking jaw 18. The adjustment handle 155 is equipped with an adjustment button 156, which is used to simultaneously trigger the telescopic push rods 151 of the two sets of single-handed clutch locking mechanisms 15.

[0027] To address the safety hazard of accidental unlocking during surgery, an anti-accidental touch button 157 is installed on the adjustment handle 155, staggered from the adjustment button 156, to control the triggering permission of the unlocking operation. The adjustment handle 155 also features an anti-accidental touch button 157, which is offset from the adjustment button 156. The anti-accidental touch button 157 has an on / off mode; when the anti-accidental touch button 157 is in the off mode, the adjustment button 156 cannot trigger the unlocking operation.

[0028] To ensure synchronized transmission of the unlocking action, a resettable adjustment button 156 is used in conjunction with a clutch cable 158 to synchronously transmit the pressing action to the two sets of telescopic push rods 151. The adjustment button 156 is configured as a resettable mechanical push switch, and the adjustment handle 155 is connected to two sets of single-handed clutch locking mechanisms 15 via the clutch cable 158. The clutch cable 158 is used to synchronously transmit the pressing action of the adjustment button 156 to the two sets of telescopic push rods 151, thereby achieving synchronous unlocking of the two sets of clutch locking mechanisms.

[0029] Regarding the assembly and fixing of the single-handed clutch locking mechanism 15, the telescopic push rod 151 is installed and positioned with the column and adjusting arm through a plug-in seat with an assembly hole 154 and a locking through hole 159. The single-handed clutch locking mechanism 15 includes a plug-in seat with an assembly hole 154 and a locking through hole 159; the sliding mounting base 13 is provided with two sets of plug-in seats, and the two sets of locking through holes 159 are respectively used for the plug-in installation of the vertical support column 12 and the horizontal adjusting arm 14, while the assembly hole 154 is used for the fixed installation of the telescopic push rod 151.

[0030] To clearly define the locking principle of the electromagnetic locking assembly 22, it incorporates an electromagnetic coil, a locking pin, and a return spring, which, in conjunction with the locking slot of the adjusting rod 21, enable energized sliding and de-energized locking. The electromagnetic locking assembly 22 includes a locking housing, an electromagnetic coil, a locking pin, and a return spring. The side wall of the adjusting rod 21 has several locking slots evenly distributed axially. The electromagnetic coil is electrically connected to the inductive switch 24. When the electromagnetic coil is energized, it attracts the locking pin, disengaging it from the locking slot of the adjusting rod 21, allowing the electromagnetic locking assembly 22 to slide freely on the adjusting rod 21. When the electromagnetic coil is de-energized, the return spring pushes the locking pin into the locking slot, achieving axial locking and fixation of the electromagnetic locking assembly 22 on the adjusting rod 21.

[0031] It should be noted that the distal retaining ring 23 is detachably fitted onto the laparoscope tube and supports the handle. It also employs a capacitive touch-sensitive switch 24 that can be encased in a sterile sleeve, balancing aseptic operation with sensing performance. The distal retaining ring 23 is detachably fitted onto the laparoscope tube and supported on the laparoscope handle. The touch-sensitive switch 24 is a capacitive touch-sensitive switch, embedded in the inner wall of the handle's grip hole and can be encased in a sterile sleeve without affecting its sensing function. To achieve radial clamping and multi-angle posture adaptation of the laparoscope, the locking jaws 18 limit the tube position via locking screws, and the elastic support arm 16 adopts a flexible, bendable, serpentine arm structure. The locking claw 18 is provided with a locking screw on its side, which is used to achieve radial clamping and limiting of the laparoscopic instrument tube; the elastic support arm 16 is a flexible serpentine arm structure that can be repeatedly bent and shaped, which can achieve multi-angle posture adjustment and remain fixed to adapt to different surgical field requirements.

[0032] In summary, the present invention also has the following combined effects: This device achieves rapid adjustment and locking of the overall position through a single-handed clutch locking mechanism 15. In the initial state, the telescopic push rod 151 extends, and the toothed pressure block 152 engages with the locking teeth 19 under the action of the support spring 153, thus fixing the sliding mounting base 13 and the lateral adjustment arm 14. After activating the anti-accidental touch button 157, pressing the adjustment button 156 with one hand simultaneously drives the two sets of telescopic push rods 151 to retract via the clutch cable 158, and the toothed pressure block 152 disengages to unlock, allowing for simultaneous adjustment of the vertical and lateral positions. After releasing the button, the device automatically resets and locks, with the locking force released axially without radial torque.

[0033] The axial adjustment of the laparoscopy is accomplished by the electromagnetic locking assembly 22 and the inductive switch 24. When the inductive switch 24 detects a grip signal, the electromagnetic coil is energized and attracts the locking pin to disengage from the slot of the adjusting rod 21. The electromagnetic locking assembly 22 can drive the distal retaining ring 23 to slide. When there is no grip signal, the electromagnetic coil is de-energized, and the reset spring pushes the locking pin into the slot to achieve axial locking. The locking jaw 18 fixes the laparoscopic tube with locking screws, the distal retaining ring 23 limits the laparoscopic handle, and the elastic support arm 16 can be bent and shaped to adapt to the surgical field of view.

[0034] The dual-group single-handed clutch locking mechanism 15 allows for simultaneous single-handed unlocking and adjustment of vertical and horizontal positions, providing convenient operation and eliminating radial torque during locking to prevent lens displacement. The misaligned design of the anti-accidental touch button 157 and adjustment button 156 prevents accidental unlocking during surgery, enhancing surgical safety. The inductive switch 24, in conjunction with the electromagnetic locking component 22, enables intelligent axial adjustment through grip unlocking and release locking, eliminating the need for manual operation of the locking components. The locking claw 18, in conjunction with the distal retaining ring 23, achieves radial and axial dual limiting of the laparoscope, ensuring stable fixation without movement. The inductive switch 24 can be encased in a sterile sleeve, and the elastic support arm 16 can be bent and shaped to adapt to surgical aseptic requirements and multi-field needs. The entire device replaces manual scope holding, reducing surgical manpower and improving the accuracy and stability of laparoscopic fixation and adjustment.

[0035] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
