Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a tissue forceps with all-round flexible control and an operating method. Background Art

[0002] In the modern medical field, laparoscopic surgery has become a common surgical method for the treatment of many abdominal diseases due to its many advantages such as small incisions and fast postoperative recovery. With the continuous advancement of medical technology and the increasing requirements of patients for surgical trauma and recovery effects, the scope of application of laparoscopic surgery is also continuing to expand. However, laparoscopic surgery also faces a series of unique challenges. One of the more prominent and urgent problems to be solved is that in the narrow abdominal operating space, due to the small surgical incision, various operating instruments need to enter the abdominal cavity through limited puncture channels at the same time for operation. This makes it very easy for the operating instruments to interfere with each other, and "fighting" often occurs. For example, when performing routine operations such as tissue grabbing and separation, when the existing tissue forceps are used together with other instruments such as electrocoagulation hooks and scissors, they will collide and block each other due to the cramped space, making it difficult for the surgical operation to proceed smoothly, increasing the difficulty and duration of the operation.

[0003] This mutual interference between instruments not only places extremely high demands on the surgeon's operating accuracy and proficiency, but may also delay key steps due to operational obstructions, affecting the smoothness of the operation and may even indirectly cause some surgical risks. Currently, most of the traditional tissue forceps on the market are designed based on conventional open surgical environments, and do not fully consider the spatial coordination issues between instruments in the special surgical scenario of laparoscopic surgery. Therefore, they expose obvious limitations in laparoscopic surgery applications.

[0004] In view of the above situation, in order to further improve the operational efficiency and safety of laparoscopic surgery and optimize the surgical process, it is urgently necessary to develop a tissue forceps with all-round flexible control, so that it can effectively avoid "fighting" with other operating instruments in the tiny incision environment of laparoscopic surgery, better assist doctors to complete various surgical operations, and promote laparoscopic surgery technology to develop in a more efficient and safe direction.

The end of the paddle located in the main rod is fixedly installed with a gear, the gear is rotatably set between rack 1 and rack 2, and meshes with rack 1 and rack 2. The ball plunger 1 is installed on the side wall of the paddle located in the hole for fixing it at any position.

[0010] As a further solution of the present invention: the pliers head comprises an upper pliers head, a lower pliers head and a pliers head rotating pin, and the pliers head is connected to the front rod via the pliers head rotating pin.

[0011] As a further solution of the present invention: the movement mechanism includes a pull rod 1, a pliers head reset spring, a steel belt, a fixed pin, a pull rod 2, a buffer spring, a trigger, a pull rod 3, a pin shaft and a handle.

[0013] A method for operating a tissue forceps with all-round flexible control, characterized in that the specific steps are as follows:

[0014] S1. According to the surgical operation requirements, adjust the angle of the flexible tube through the knob mechanism, use the paddle to drive the gear to rotate, combine with the ball plunger to fix the flexible tube at the required angle, and send the tissue forceps into the appropriate position in the abdominal cavity through the puncture channel;

[0015] S2. If the rotation angle of the forceps head needs to be adjusted, the rotating mechanism can be operated. Through the cooperation of the impeller and other components, the ball plunger is limited and the bearing is lubricated, so that the forceps head can be rotated to a suitable direction to facilitate alignment with the target tissue;

[0016] S3. The doctor holds the handle and pulls the trigger according to the actual grasping force required. Through the linkage of various components in the motion mechanism, the pull rod drives the forceps head to close with the cooperation of the forceps head reset spring, etc., to grasp the target tissue;

[0017] S4. After the grasping is completed, release the trigger. Under the reset action of the springs and components, the forceps head automatically opens, and the next operation can be carried out or the position of the tissue clamp can be adjusted according to the progress of the operation.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The head of the tissue forceps adopts a non-damaging tooth design. This unique design can significantly reduce unnecessary damage to normal tissue during tissue clamping, greatly improving the safety and accuracy of the operation. In the middle part of the tissue forceps, a flexible tube structure is carefully constructed. The special structure of the flexible tube enables it to bend flexibly in the left and right directions, which is convenient for adapting to different angles and position requirements during surgical operations, avoiding instrument interference, and expanding operational flexibility, so that the tissue forceps can be operated more freely in narrow surgical incisions. In addition, the position of the snake bone tube is also intimately covered with a highly flexible plastic protective film (outer tube). This protective film, on the basis of ensuring that it does not affect the transmission efficiency, successfully realizes that the rotary cutting tube can be rotated freely in both directions without hindrance, effectively avoiding the occurrence of jamming problems, and further ensuring the smoothness and stability of surgical operations. The flexible The rear end of the tube is connected to a hollow main rod, which is divided into two parts, an upper and a lower part. A rack is precisely placed inside the main rod, and the rack is tightly connected to the steel wire of the snake tube. The specially designed rotating mechanism drives the rack to move in the front-to-back direction, thereby cleverly achieving the precise bending of the snake tube, allowing the tissue forceps to flexibly adjust the angle according to surgical needs. The rear end of the main rod is equipped with a wave wheel, and the existence of this wave wheel enables the entire instrument to rotate 360° in all directions, thereby achieving omnidirectional bending of the forceps head, providing an extremely wide operating space and angle selection for surgical operations. It is worth mentioning that the closing action of the forceps head is driven by the steel belt, and even when the flexible tube is in a bent state, the clamping action can still be completed stably and reliably, ensuring the integrity and effectiveness of the tissue forceps function during the operation, and effectively promoting the smooth development and technical improvement of laparoscopic surgery.
