Abstract
Description
Technical Field
[0001] The invention relates to the technical field of suturing, in particular to an intelligent positioning suturing device for gastrointestinal anastomosis. Background Art
[0002] In gastrointestinal surgery, gastrointestinal anastomosis is a critical step, with the quality and precision of suturing directly impacting patients' postoperative recovery and quality of life. Traditional gastrointestinal anastomosis procedures rely primarily on manual labor, which not only requires exceptional skill and experience, but also takes a long time, causes significant pain for the patient, and carries a relatively high risk of postoperative complications. With the continuous advancement of medical technology, intelligent positioning and suturing devices for gastrointestinal anastomosis have emerged, revolutionizing gastrointestinal anastomosis surgery. Currently, intelligent positioning and suturing devices for gastrointestinal anastomosis are gradually incorporating intelligent sensing technology into the anastomotic tip to enhance positioning accuracy and improve surgical outcomes. Some advanced devices cleverly integrate pressure sensors, such as resistive strain gauge sensors, into the clamping mechanism of the anastomotic tip. These sensors monitor the clamping pressure applied to the gastrointestinal tissue in real time and transmit the pressure signal to a microcontroller. The microcontroller automatically adjusts the output force of the drive mechanism according to a pre-set program to maintain the clamping pressure within a preset safety range. Their operating principle is similar to that of an "intelligent constant-force clamp." Through this pressure feedback control mechanism, compared with the traditional manual adjustment method, the accuracy and stability of force control during the positioning process are significantly improved, effectively avoiding damage to gastrointestinal tissue due to improper clamping force, and providing a certain guarantee for the safety and effectiveness of the operation.
[0003] However, although the pressure sensor can monitor the stress of gastrointestinal tissue in real time, gastrointestinal tissue has its own special physiological characteristics. During the operation, the gastrointestinal tissue will produce periodic displacement due to the patient's own respiratory movement. At the same time, various touches during the surgical operation can easily cause the gastrointestinal tissue to shift. This displacement phenomenon will cause the clamping position to deviate from the pre-set target area, thereby affecting the accuracy of the anastomosis. More importantly, the pressure feedback mechanism of existing devices is mostly based on static threshold adjustment. This means that when the gastrointestinal tissue is displaced, the pressure change monitored by the pressure sensor only reflects the change in tissue stress, and the device lacks the ability to actively compensate for the dynamic displacement of the tissue. In this case, the doctor needs to frequently manually adjust the position of the intestinal tissue to ensure that the intestinal tissue is realigned with the limiting structure, making the entire operation process cumbersome and complicated, which not only increases the doctor's workload, but also affects the continuity and efficiency of intelligent positioning suture. Summary of the Invention
[0004] In response to the problems in the prior art, the present invention provides an intelligent positioning and suturing device for gastrointestinal anastomosis. In order to solve the above-mentioned problems, the present invention proposes an intelligent positioning and suturing device for gastrointestinal anastomosis, which solves the problem that during the existing operation, the gastrointestinal tissue will produce periodic displacement due to the patient's own respiratory movement. At the same time, various touches during the surgical operation can easily cause the gastrointestinal tissue to be displaced. This displacement phenomenon will cause the clamping position to deviate from the pre-set target area, thereby affecting the accuracy of the anastomosis. More importantly, the pressure feedback mechanism of the existing device is mostly based on static threshold adjustment. This means that when the gastrointestinal tissue is displaced, the pressure change monitored by the pressure sensor only reflects the change in tissue force, and the device lacks the ability to actively compensate for the dynamic displacement of the tissue. In this case, the doctor needs to frequently manually adjust the position of the intestinal tissue to ensure that the intestinal tissue is realigned with the limiting structure, making the entire operation process cumbersome and complicated, which not only increases the doctor's workload, but also affects the continuity and efficiency of the intelligent positioning suturing.

DETAILED DESCRIPTION
[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0016] like Figures 1-6 As shown, the present invention provides the following technical solutions: Embodiment 1: Gastrointestinal anastomosis intelligent positioning suturing device, including an intelligent stapler 1, one end of the intelligent stapler 1 is fixedly connected to an operating rod 2, one end of the operating rod 2 is fixedly connected to an anastomotic end 3, the upper and lower ends of the operating rod 2 are fixedly connected to guide rails 12, the outer movable sleeve of the operating rod 2 is provided with a movable ring 11, the movable ring 11 is slidably connected to the two guide rails 12 through two guide grooves 14, the bottom end of the movable ring 11 is fixedly connected to a bottom block 15, a positioning component 9 is provided on one side of the upper end of the movable ring 11, the positioning component 9 corresponds to the positioning groove 13 provided on the outer wall of the operating rod 2, and both sides of the bottom end of the movable ring 11 are fixedly connected to protrusions 10; Support rods 4 are provided on both sides of the anastomotic end 3, one end of the two support rods 4 is fixedly connected to the limit rod 5, and the other ends of the two support rods 4 are respectively fixedly sleeved with the two protrusions 10, and the ends of the two support rods 4 away from the limit rod 5 are provided with a negative pressure assembly 7; the negative pressure assembly 7 includes a connecting rod 71, both ends of the connecting rod 71 are fixedly connected to the mounting rod 74, one end of the two mounting rods 74 is respectively inserted into the inside of the two support rods 4 and fixedly connected to the piston 75, a screw rod 72 is threadedly connected to the center position of the connecting rod 71, one end of the screw rod 72 is rotatably connected to one side of the bottom block 15, and the other end of the screw rod 72 is fixedly connected to the turning handle 73; The positioning assembly 9 includes a pulling block 91, a pulling ring 92 is fixedly connected to the center position of the upper end of the pulling block 91, and a second spring 93 is fixedly connected between the two sides of the bottom end of the pulling block 91 and the movable ring 11. The bottom end of the pulling block 91 is fixedly connected to a positioning block 94, and the bottom end of the positioning block 94 passes through the movable ring 11 and is movably inserted into the corresponding positioning groove 13.

The negative pressure then flows through the second through holes 8 to make the gastrointestinal tissue tightly adhere to the inner sides of the limiting rods 5, thereby further ensuring the stability of the gastrointestinal tissue. The ends of the two limiting rods 5 and the tops of the two fixing rods 61 are both spherical, and the arc centers of the two limiting rods 5 are both horizontally consistent with the angles of the anastomotic ends 3 to ensure the limiting effect on the gastrointestinal tissue.
[0017] When in use, the gastrointestinal tissue is first clamped at the junction of the limit rod 5 and the support rod 4, and then the pulling block 91 is pulled up by the pulling ring 92. The pulling block 91 drives the positioning block 94 to move up and stretches the second spring 93. When the positioning block 94 is completely separated from the positioning groove 13, the movable ring 11 can be slid along the operating rod 2.

[0018] Embodiment 2: The technical solution of this embodiment is different from that of embodiment 1 and includes: a clamping assembly 6 is further provided on one side of the two limit rods 5, each clamping assembly 6 includes a fixing rod 61, the fixing rod 61 is fixed to the outside of the support rod 4, the top of the fixing rod 61 is set to be spherical, the fixed rod 61 is set to be arc-shaped, and a plurality of first through holes 65 are provided on the inner side of the fixing rod 61, and the side of the fixing rod 61 close to the limit rod 5 is fixedly connected with a clamping block 63 through a telescopic rod 62, and a first spring 64 is fixedly connected between the clamping block 63 and the fixed section of the telescopic rod 62, and the first spring 64 is sleeved on the outer periphery of the telescopic section of the telescopic rod 62, and the telescopic rod 62 and the clamping block 63 are both set to be hollow, and the clamping block 63 cooperates with the limit rod 5 to stably clamp the gastrointestinal tissue, thereby greatly improving the stability of the gastrointestinal tissue, thereby improving the positioning accuracy and operation efficiency.
[0019] When in use, before the gastrointestinal tissue is clamped at the junction of the support rod 4 and the limit rod 5, the clamp block 63 is pushed. When the clamp block 63 is close to the fixed rod 61, the first spring 64 is squeezed. When the gastrointestinal tissue is clamped at the junction of the support rod 4 and the limit rod 5, the clamp block 63 is released.
